ABSTRACT

Objective: To evaluate and compare the effect of semi-rigid ureterorenoscopy on post-procedural sexual function with three different operating room settings. Methods: In this prospective randomized study, consecutive sexually active patients with normal pre-operative sexual function undergoing uncomplicated semi-rigid ureterorenoscopy for distal ureteric stones were randomized into three groups, with three different operating room settings. Procedure-related anxiety and sexual function were assessed pre-operatively using Amsterdam Preoperative Anxiety and Information Scale and Brief Sexual Function Inventory (in males) and Female Sexual Function Index-6 (in females), respectively. All the participants were stented following the procedure, and the stent was removed after 3 weeks. Post-procedural sexual function and general discomfort were assessed and compared between three groups at 1 week, 3 weeks, and 12 weeks. The effect of surgery-related anxiety, preoperative sexual function, age, and general discomfort (including stent-related discomfort) on post-procedural sexual function were analyzed using multiple regression analysis. A p-value of less than 0.05 was considered statistically significant. Results: Totally, 327 eligible patients were randomized into three groups. The group of patients who underwent the procedural with a screen separating the operating area from the patient vision, while the patient could watch the endoscopy through a separate monitor, had better post-procedural sexual function compared to those who had total vision of the operating area as well as to those whose eyes were blocked. This difference was statistically significant. This post-procedural reduction in sexual function could not be attributed to in situ stent alone. Conclusions: Our study showed that semi-rigid ureterorenoscopy can have significant negative effect on sexual function, which can be reduced with proper preoperative counseling and an ideal operating room settings.

ABSTRACT

BACKGROUND: Combined knee valgus and tibial internal rotation (VL + IR) moments have been shown to stress the anterior cruciate ligament (ACL) in several in vitro cadaveric studies. To utilize this knowledge for non-contact ACL injury prevention in sports, it is necessary to elucidate how the ground reaction force (GRF) acting point (center of pressure (CoP)) in the stance foot produces combined knee VL + IR moments in risky maneuvers, such as cuttings. However, the effects of the GRF acting point on the development of the combined knee VL + IR moment in cutting are still unknown. METHODS: We first established the deterministic mechanical condition that the CoP position relative to the tibial rotational axis differentiates the GRF vector's directional probability for developing the combined knee VL + IR moment, and theoretically predicted that when the CoP is posterior to the tibial rotational axis, the GRF vector is more likely to produce the combined knee VL + IR moment than when the CoP is anterior to the tibial rotational axis. Then, we tested a stochastic aspect of our theory in a lab-controlled in vivo experiment. Fourteen females performed 60° cutting under forefoot/rearfoot strike conditions (10 trials each). The positions of lower limb markers and GRF data were measured, and the knee moment due to GRF vector was calculated. The trials were divided into anterior- and posterior-CoP groups depending on the CoP position relative to the tibial rotational axis at each 10 ms interval from 0 to 100 ms after foot strike, and the occurrence rate of the combined knee VL + IR moment was compared between trial groups. RESULTS: The posterior-CoP group showed significantly higher occurrence rates of the combined knee VL + IR moment (maximum of 82.8%) at every time point than those of the anterior-CoP trials, as theoretically predicted by the deterministic mechanical condition. CONCLUSION: The rearfoot strikes inducing the posterior CoP should be avoided to reduce the risk of non-contact ACL injury associated with the combined knee VL + IR stress.

ABSTRACT

The 2-substituted benzoxazole derivatives are known to exhibit a wide spectrum of biological potential. Two series of novel benzoxazole derivatives containing 2-phenyl and 2-N-phenyl groups were synthesized, by following the green chemistry approach. All the newly synthesized derivatives were screened against gram-positive bacteria (Streptococcus pyogenes, Staphylococcus aureus), gram-negative bacteria (Pseudomonas aeruginosa, Escherichia coli) and the fungus (Aspergillus clavatus and Candida albicans). Most of these compounds have demonstrated potent antibacterial activities, especially against E. coli at 25 µg/mL, along with moderate antifungal activity. Among these, two compounds, 21 and 18, showed interesting antibacterial profile. Molecular docking studies suggested that the antibacterial activity can be linked to the inhibition of DNA gyrase. Overall, the study proposes that these biologically potent compounds can be considered for developing the next generation antimicrobial agents.

ABSTRACT

Background: Precise postural control helps prevent anterior cruciate ligament injury. However, it is unknown whether the anticipated postural stability can be improved during a physically uncertain and cognitively demanding task. Hypothesis: Anticipated postural stability will improve through unanticipated single-leg landing with a rapid foot placement target tracking. Study Design: Controlled laboratory study. Methods: A total of 22 healthy female university-level athletes performed a novel dual-task paradigm: an unanticipated single-leg landing with foot placement target tracking. In the normal condition (60 trials), the participants jumped from a 20 cm-high box onto the landing target with their dominant leg as softly as possible. In the subsequent perturbation condition (PC) (60 trials), the initially assigned landing target was abruptly switched randomly, requiring participants to modify their preplanned foot placement position to the newly assigned position. The center-of-pressure trajectory length within the first 100 ms after foot impact (CoP100) was calculated as a measure of anticipated postural stability for each trial. In addition, the peak vertical ground-reaction force (FzPeak) was quantified to assess landing load, and the degree of postural adaptation during PC was quantified by fitting an exponential function to trial-by-trial changes in CoP100. Participants were divided into 2 groups according to increase or decrease in CoP100, and results were compared between the groups. Results: The direction and magnitude of postural sway alterations of the 22 participants showed a spectrum-like variation during the repeated trials. Twelve participants (sway-decreased group) exhibited a gradual reduction in postural sway (CoP100) during the PC, while the remaining 10 participants (sway-increased group) showed a gradual increase in CoP100. The FzPeak during the PC was significantly less in the sway-decreased group compared with the sway-increased group (P < .05). Conclusion: Variation in the direction and magnitude of postural sway alteration among participants suggested that there was individual variation in an athlete's adaptive ability of the anticipated postural stability. Clinical Relevance: The novel dual-task paradigm described in this study may be useful for rating individual injury risk based on an athlete's postural adaptation ability and may aid in targeted prevention strategies.

ABSTRACT

Aim: To assess the clinical improvement after single dose topical application of 1% clotrimazole cream in otomycosis and follow up for recurrence at the end of first and the third month. Materials and Methods: A prospective observational study was carried out at Government Medical college hospital. Patients with KOH diagnosed fungal infection of external auditory canal were included in the study. After obtaining informed written consent from the participating patients, a detail clinical history was taken. Single topical application of 1% clotrimazole cream in otomycosis. The fungal debris was removed with the help of suction aspiration and dry mopping. A single topical application of 1% clotrimazole cream was applied under all aseptic precautions. On the 3rd day the applied cream was cleaned with help of suction under ear microscope. Patients were advised to follow up after one month and three months. During each follow up patients were assessed clinically and examined for residual fungal debris. Result: Otomycosis was seen predominantly in middle aged females, housewives and laborers by occupation. Earache was most common symptom seen in 65.2%. Unilateral involvement was seen in 89.3% cases. The most common organism isolated in otomycosis was Aspergillus niger. At the end of one month of treatment with a single dose of 1% clotrimazole cream, 102 (91.0%) patients were recovered and 10 (9.0%) patients were with persistence or recurrence of the symptoms. At the end of third month, the recovery rate was 84.8% and recurrence rate was 6.3%. Conclusion: Single topical application of 1% clotrimazole cream is effective in treating otomycosis.

ABSTRACT

BACKGROUND: Impulsive compulsive behaviors (ICBs) often disturb patients with Parkinson's Disease (PD), of which impulse control disorder (ICD) and dopamine dysregulation syndrome (DDS) are two major subsets. The nucleus accumbens (NAcc) is involved in ICB; however, it remains unclear how the NAcc affects cortical function and defines the different behavioral characteristics of ICD and DDS. OBJECTIVES: To identify the cortico-striatal network primarily involved in ICB and the differences in these networks between patients with ICD and DDS using structural and resting-state functional magnetic resonance imaging. METHODS: Patients with PD were recruited using data from a previous cohort study and divided into those with ICB (ICB group) and without ICB (non-ICB group) using the Japanese version of the Questionnaire for Impulsive Compulsive Disorders in Parkinson's Disease (J-QUIP). From these two groups, we extracted 37 pairs matched for age, sex, disease duration, and levodopa equivalent daily dose of dopamine agonists. Patients with ICB were further classified as having ICD or DDS based on the J-QUIP subscore. General linear models were used to compare gray matter volume and functional connectivity (FC) of the NAcc, caudate, and putamen between the ICB and non-ICB groups and between patients with ICD and those with DDS. RESULTS: We found no significant differences in gray matter volumebetween the ICB and non-ICB groups or between patients with ICD and those with DDS. Compared with the non-ICB group, the FC of the right NAcc in the ICB group was lower in the bilateral ventromedial prefrontal cortex and higher in the left middle occipital gyrus. Furthermore, patients with DDS showed higher FC between the right putamen and left superior temporal gyrus and higher FC between the left caudate and bilateral middle occipital gyrus than patients with ICD. In contrast, patients with ICD exhibited higher FC between the left NAcc and the right posterior cingulate cortex than patients with DDS. CONCLUSIONS: The functionally altered network between the right NAcc and ventromedial prefrontal cortex was associated with ICB in PD. In addition, the surrounding cortico-striatal networks may differentiate the behavioral characteristics of patients with ICD and those with DDS.

ABSTRACT

Patients with Parkinson's disease (PD) often suffer from sleep disturbances, including excessive daytime sleepiness (EDS) and rapid eye movement sleep behavior disorder (RBD). These symptoms are also experienced by patients with narcolepsy, which is characterized by orexin neuronal loss. In PD, a decrease in orexin neurons is observed pathologically, but the association between sleep disturbance in PD and cerebrospinal fluid (CSF) orexin levels is still unclear. This study aimed to clarify the role of orexin as a biomarker in patients with PD. CSF samples were obtained from a previous cohort study conducted between 2015 and 2020. We cross-sectionally and longitudinally examined the association between CSF orexin levels, sleep, and clinical characteristics. We analyzed 78 CSF samples from 58 patients with PD and 21 samples from controls. CSF orexin levels in patients with PD (median = 272.0 [interquartile range = 221.7-334.5] pg/mL) were lower than those in controls (352.2 [296.2-399.5] pg/mL, p = 0.007). There were no significant differences in CSF orexin levels according to EDS, RBD, or the use of dopamine agonists. Moreover, no significant correlation was observed between CSF orexin levels and clinical characteristics by multiple linear regression analysis. Furthermore, the longitudinal changes in orexin levels were also not correlated with clinical characteristics. This study showed decreased CSF orexin levels in patients with PD, but these levels did not show any correlation with any clinical characteristics. Our results suggest the limited efficacy of CSF orexin levels as a biomarker for PD, and that sleep disturbances may also be affected by dysfunction of the nervous system other than orexin, or by dopaminergic treatments in PD. Understanding the reciprocal role of orexin among other neurotransmitters may provide a better treatment strategy for sleep disturbance in patients with PD.

ABSTRACT

The present study was undertaken to evaluate lipid profile in tobacco consumers with and without head and neck malignancy and to see whether tobacco consumption causes same degree of alteration in lipid profile. Prospective study of serum lipid profile in 90 patients was done at Govt. Medical College Hospital. Various details of all participants such as age and sex of patients, detailed history of tobacco consumption were taken. Patients were divided into group I, II and III. Serum lipid profile was studied in 30 patients with tobacco addicts for more than 5 years in the form of tobacco chewing and smoking without head-neck malignancy (Group I), 30 patients with tobacco addicts for more than 5 yrs in the form of tobacco chewing and smoking with head-neck malignancy (Group II) and 30 controls i.e., non-smokers and non-tobacco chewers (Group III). Statistical analysis was done to compare the serum lipid profile (Total Cholesterol, HDL, Ratio, Sr. triglyceride, VLDL, LDL) among the tobacco chewers with head and neck malignancy, non-tobacco consumers and tobacco consumers without malignancy and controls i.e., non-smokers and non-tobacco chewers. There was no significant change in total cholesterol, LDL, VLDL, HDL in patients with tobacco addicts and tobacco non-addicts. Serum triglycerides are significantly decreased in tobacco addicts and in malignancy. Total cholesterol, HDL, and LDL are significantly increased in malignancy as compared to tobacco addicts and tobacco non-addicts. There was no significant change in total cholesterol, LDL, VLDL, HDL in patients with tobacco addicts and tobacco non-addicts. Serum triglycerides are significantly decreased in tobacco addicts and in malignancy.

ABSTRACT

The ground reaction force (GRF) is known to produce tibial internal rotation loading associated with the stress in the anterior cruciate ligament (ACL). However, it is unclear whether the friction moment (FM; the moment due to horizontal shoe-floor friction, acting around the vertical axis at the GRF acting point) facilitates or restrains the effect of GRF-driven tibial rotation loading during cutting. The 45° cutting motions with forefoot/rearfoot strikes were captured simultaneously with GRF and FM data from 23 healthy males. The FM- and GRF-driven tibial rotation moments were calculated. Time-series correlation between FM- and GRF-driven tibial rotation moments and the orientation relationship among those moment vectors was investigated. The FM-driven tibial rotation moment negatively correlated with the GRF-driven one within the first 10% of stance phase. The peak regression slope value was -0.34 [SD 0.33] for forefoot and -1.64 [SD 1.76] for rearfoot strikes, showing significant difference from zero (SPM one-sample t-test, p<0.05). The FM-driven tibial "external" rotation moment counteracted the GRF-driven tibial "internal" rotation moment within first 10% of the stance phase in most trials, suggesting that the FM-driven tibial rotation moment potentially diminishes the effect of GRF-driven one and may reduce ACL injury risk during cutting.

ABSTRACT

BACKGROUND: Postpartum pelvic floor dysfunction is known to affect the quality of life of women and the methods to treat it are more complex with majority requiring training under supervision. AIM: To compare the efficacy of sexually induced orgasm along with Kegels exercises versus Kegels exercises alone as a treatment method to enhance postpartum pelvic floor muscle strength and sexual function in primiparous women undergoing uncomplicated vaginal deliveries. METHODS: The prospective randomized two-arm study was conducted on sexually active primiparous women who had undergone uncomplicated vaginal deliveries. Those with risk factors for female sexual dysfunction and pelvic floor muscle dysfunction were excluded. Participants in Group 1 were advised daily Kegel's exercises, whereas, those in Group 2 were advised to initiate self-initiated/partnered sexual activity-induced orgasms along with daily Kegel's exercises. Their pelvic floor muscle strength on voluntary contraction, ability to relax pelvic floor voluntarily, and sexual function (using FSFI-6) were assessed monthly for 6 months and the analysis was done using G* Power software (© 2021 Heinrich-Heine-Universität Düsseldorf, Germany). MAIN OUTCOME MEASURE: Postpartum pelvic floor strength and sexual function in 2 groups of women under study. RESULTS: The study period was from January 2020 to December 2020. The Group 1 had 26 participants (mean age 29.69 ± 2.2 years) and Group 2 had 29 participants (mean age 30.07 ± 2.57 years). The sexual function as well as ability to relax pelvic floor were significantly better in Group 2 compared to Group 1 at each monthly intervals whereas strength of pelvic floor muscles during voluntary contraction was significantly higher in Group 2 compared to Group 1 at the end of 6 months and it was statistically significant at a P value of .05. CLINICAL IMPLICATIONS: Novel method of using naturally occurring sexually induced orgasms for postpartum pelvic floor rehabilitation can revolutionize postpartum pelvic floor training in women, as it can be practiced at home with ease, along with easily performable Kegel's exercises. STRENGTHS AND LIMITATIONS: Use of prospective randomization and minimization of confounding factors is the strength of the study. The small sample size is the limitation of the study. CONCLUSIONS: Postpartum pelvic floor muscle strength and sexual function in primiparous women who have undergone uncomplicated vaginal deliveries can be significantly improved with the addition of sexually induced orgasm as a therapeutic tool along with physical exercises such as Kegels exercises in these women.

ABSTRACT

Chain-length-specific subsets of diacylglycerol (DAG) lipids are proposed to regulate differential physiological responses ranging from signal transduction to modulation of the membrane properties. However, the mechanism or molecular players regulating the subsets of DAG species remain unknown. Here, we uncover the role of a conserved eukaryotic protein family, DISCO-interacting protein 2 (DIP2) as a homeostatic regulator of a chemically distinct subset of DAGs using yeast, fly, and mouse models. Genetic and chemical screens along with lipidomics analysis in yeast reveal that DIP2 prevents the toxic accumulation of specific DAGs in the logarithmic growth phase, which otherwise leads to endoplasmic reticulum stress. We also show that the fatty acyl-AMP ligase-like domains of DIP2 are essential for the redirection of the flux of DAG subspecies to storage lipid, triacylglycerols. DIP2 is associated with vacuoles through mitochondria-vacuole contact sites and such modulation of selective DAG abundance by DIP2 is found to be crucial for optimal vacuole membrane fusion and consequently osmoadaptation in yeast. Thus, the study illuminates an unprecedented DAG metabolism route and provides new insights on how cell fine-tunes DAG subspecies for cellular homeostasis and environmental adaptation.


Lipids, such as fats and hormones, constitute one of the main building blocks of cells. There are thousands of different lipids each with distinctive chemical properties that allow them to carry out specific roles. For example, a group of lipids called diacylglycerols help cells perform a myriad of tasks, like sensing external signals, making membranes, and storing energy. The production and breakdown of diacylglycerols is therefore tightly regulated. However, very little is known about the molecules involved in this metabolic process. One possible candidate is the enzyme DIP2 which is comprised of a protein module known as FAAL (short for fatty acyl-AMP ligase). FAAL belongs to a family of enzymes that synthesize lipid-like molecules in bacteria. In 2021, a group of researchers tracked the evolutionary trajectory of these bacterial proteins and found that most of them were lost in eukaryotes, such as animals and fungi. FAAL-like proteins, however, had been retained through evolution and incorporated in to DIP2. Here, Mondal, Kinatukara et al. ­ including some of the researchers involved in the 2021 study ­ have used a combination of genetic and biochemical experiments to investigate whether and how DIP2 contributes to lipid metabolism in eukaryotes. They found that yeast cells without the gene for DIP2 had higher levels of diacylglycerols which hampered the shape and function of certain cellular compartments. The mutant cells were also unable to convert diacylglycerols in to another group of lipids which are involved in energy storage. This effect was observed in fruit flies and mice lacking DIP2, suggesting that this role for DIP2 is conserved across most eukaryotes. Further experiments in yeast cells revealed that unlike other enzymes that metabolize diacylglycerols, DIP2 only acted on a sub-population of diacylglycerols at specific locations and times. Furthermore, yeast cells lacking DIP2 could still grow under ideal conditions, but could not cope with high or low salt concentrations in their surroundings, suggesting that the enzyme helps cells deal with environmental stresses. Since DIP2 is found in most eukaryotes, understanding how it works could be useful for multiple branches of biology. For example, some pathogenic fungi that cause diseases in crop plants and humans also rely on DIP2. Further studies are needed to better understand the role that DIP2 plays in other eukaryotic species which may shed light on other processes the enzyme is involved in.

ABSTRACT

Premature ejaculation (PE) is considered as a disorder of perceived loss of ejaculatory control. However, we cannot objectively estimate ejaculatory control due to the absence of an objective tool to measure it. Hence, we designed a pilot study to validate holding time (HoT), a novel objective tool, hypothesized by us, to measure ejaculatory control in men. The construct validity of this tool to differentiate premature ejaculators from normal ejaculators was also assessed in our sample. The study sample had 10 healthy, sexually active normal ejaculators, and 10 premature ejaculators, who volunteered to participate in the study conducted from May 2020 to April 2021. The mean HoT in normal ejaculators was 120.2 ± 31.7 s and the same in premature ejaculators was 32.9 ± 12.9 s. Both the normal (r = 0.983) as well as premature ejaculators (r = 0.839) had good test-retest reliability. The construct validity of HoT to diagnose PE was good with 90% sensitivity, 91% specificity, 63.8% positive predictive value, and 98.1% negative predictive value to diagnose PE when compared with diagnosis by a standard tool. It could be concluded that HoT successfully measured ejaculatory control in men and differentiated normal ejaculators from the premature ejaculators in the sample studied.

ABSTRACT

AIM: During the second wave of COVID-19, cases of mucormycosis were increased suddenly over a period of 3 months in Maharashtra, India. An attempt was made to study the clinical profile and risk factors associated with mucormycosis. MATERIALS AND METHODS: A retrospective descriptive study was carried out at a tertiary hospital during May 2021-July 2021. After obtaining informed written consent from the participants, various details of all participants, such as diabetes mellitus, use of steroids in COVID-19 treatment, use of immunosuppressant drugs, oxygen therapy, use of ventilators, complications that occurred during treatment, etc., were noted. All mucormycosis patients were treated with amphotericin B and aggressive surgical treatment. RESULTS: In the present study, 74.7% of mucormycosis patients were male. 77.4% of mucormycosis patients were above 40 years of age. 6.7% of mucormycosis patients were partially vaccinated. Among risk factors, 86.6% had diabetes mellitus, 84% had COVID-19 infection, 44% had received steroids, and 54.7% had received oxygen. 80% of patients were present during and within 1 month of COVID-19 infection. 52% of patients were presented in stage III and 41.3% were presented in stage II. Despite aggressive surgical debridement along with amphotericin B, mortality was 25.33%. 5.3% of patients had brain abscesses, 8% of patients had cavernous sinus thrombosis, 4% of patients had facial nerve palsy and 1.3% of patients had meningitis. CONCLUSION: Mucormycosis was predominantly seen in male above the age of 40 years COVID-19 infection and diabetes mellitus was common risk factor for mucormycosis.

ABSTRACT

Global energy consumption has been increasing in tandem with economic growth motivating researchers to focus on renewable energy sources. Dark fermentative hydrogen synthesis utilizing various biomass resources is a promising, less costly, and less energy-intensive bioprocess relative to other biohydrogen production routes. The generated acidogenic dark fermentative effluent [e.g., volatile fatty acids (VFAs)] has potential as a reliable and sustainable carbon substrate for polyhydroxyalkanoate (PHA) synthesis. PHA, an important alternative to petrochemical based polymers has attracted interest recently, owing to its biodegradability and biocompatibility. This review illustrates methods for the conversion of acidogenic effluents (VFAs), such as acetate, butyrate, propionate, lactate, valerate, and mixtures of VFAs, into the value-added compound PHA. In addition, the review provides a comprehensive update on research progress of VFAs to PHA conversion and related enhancement techniques including optimization of operational parameters, fermentation strategies, and genetic engineering approaches. Finally, potential bottlenecks and future directions for the conversion of VFAs to PHA are outlined. This review offers insights to researchers on an integrated biorefinery route for sustainable and cost-effective bioplastics production.

ABSTRACT

We are reporting on the impact of air annealing temperatures on the physicochemical properties of electrochemically synthesized cadmium selenium telluride (CdSe0.6Te0.4) samples for their application in a photoelectrochemical (PEC) solar cell. The CdSe0.6Te0.4 samples were characterized with several sophisticated techniques to understand their characteristic properties. The XRD results presented the pure phase formation of the ternary CdSe0.6Te0.4 nanocompound with a hexagonal crystal structure, indicating that the annealing temperature influences the XRD peak intensity. The XPS study confirmed the existence of Cd, Se, and Te elements, indicating the formation of ternary CdSe0.6Te0.4 compounds. The FE-SEM results showed that the morphological engineering of the CdSe0.6Te0.4 samples can be achieved simply by changing the annealing temperatures from 300 to 400 °C with intervals of 50 °C. The efficiencies (ƞ) of the CdSe0.6Te0.4 photoelectrodes were found to be 2.0% for the non-annealed and 3.1, 3.6, and 2.5% for the annealed at 300, 350, and 400 °C, respectively. Most interestingly, the PEC cell analysis indicated that the annealing temperatures played an important role in boosting the performance of the photoelectrochemical properties of the solar cells.

ABSTRACT

'Yips' in golf is a complex spectrum of anxiety and movement-disorder that affects competitive sporting performance. With unclear etiology and high prevalence documented in western literature, the perception and management of this psycho-neuromuscular problem among Japanese elite golfers is unknown. The objective of this study was to explore factors associated with yips, investigate the performance deficits and the strategies implemented to prevent yips. We surveyed approx. 1300 professional golfers on their golfing habits, anxiety and musculoskeletal problems, kinematic deficits, changes in training and their outcomes. Statistical procedures included multiple logistic regression and network analysis. 35% of the respondents had experienced yips in their career, their odds increasing proportionally to their golfing experience. Regardless of musculoskeletal symptoms, about 57% of all yips-golfers attributed their symptoms to psychological causes. Network analysis highlighted characteristic movement patterns, i.e. slowing, forceful or freezing of movement for putting, approach and teeing shots respectively. Golfers' self-administered strategies to relieve yips were mostly inconsequential. Within the limits of our self-reported survey, most golfers perceived yips as a psychological phenomenon despite evidence pointing to a movement-disorder. While self-administered interventions were satisfactory at best, it may be imperative to sensitize golfers from a movement-disorder standpoint for early management of the problem.

ABSTRACT

The precise neural underpinnings of face pareidolia in patients with Parkinson's disease (PD) remain unclear. We aimed to clarify face recognition network abnormalities associated with face pareidolia in such patients. Eighty-three patients with PD and 40 healthy controls were recruited in this study. Patients with PD were classified into pareidolia and nonpareidolia groups. Volumetric analyses revealed no significant differences between the pareidolia (n = 39) and nonpareidolia (n = 44) patient groups. We further observed decreased functional connectivity among regions of interest in the bilateral frontotemporal lobes in patients with pareidolia. Seed-based analysis using bilateral temporal fusiform cortices as seeds revealed significantly decreased connectivity with the bilateral inferior medial prefrontal cortices in the pareidolia group. Post hoc regression analysis further demonstrated that the severity of face pareidolia was negatively correlated with functional connectivity between the bilateral temporal fusiform and medial prefrontal cortices. Our findings suggest that top-down modulation of the face recognition network is impaired in patients with PD experiencing face pareidolia.

ABSTRACT

The COVID-19 pandemic has negatively impacted sporting activities across the world. However, practical training strategies for athletes to reduce the risk of infection during the pandemic have not been definitively studied. The purpose of this report was to provide an overview of the challenges we encountered during the reboot of high-performance sporting activities of the Japanese national handball team during the 3rd wave of the COVID-19 pandemic in Tokyo, Japan. Twenty-nine Japanese national women's handball players and 24 staff participated in the study. To initiate the reboot of their first training camp after COVID-19 stay-home social policy, we conducted: web-based health-monitoring, SARS-CoV-2 screening with polymerase chain reaction (PCR) tests, real-time automated quantitative monitoring of social distancing on court using a moving image-based artificial intelligence (AI) algorithm, physical intensity evaluation with wearable heart rate (HR) and acceleration sensors, and a self-reported online questionnaire. The training camp was conducted successfully with no COVID-19 infections. The web-based health monitoring and the frequent PCR testing with short turnaround times contributed remarkably to early detection of athletes' health problems and to risk screening. During handball, AI-based on-court social-distance monitoring revealed key time-dependent spatial metrics to define player-to-player proximity. This information facilitated appropriate on- and off-game distancing behavior for teammates. Athletes regularly achieved around 80% of maximum HR during training, indicating anticipated improvements in achieving their physical intensities. Self-reported questionnaires related to the COVID management in the training camp revealed a sense of security among the athletes that allowed them to focus singularly on their training. The challenges discussed herein provided us considerable knowledge about creating and managing a safe environment for high-performing athletes in the COVID-19 pandemic via the Japan Sports-Cyber Physical System (JS-CPS) of the Sports Research Innovation Project (SRIP, Japan Sports Agency, Tokyo, Japan). This report is envisioned to provide informed decisions to coaches, trainers, policymakers from the sports federations in creating targeted, infection-free, sporting and training environments.

ABSTRACT

Fatty acyl-AMP ligases (FAALs) channelize fatty acids towards biosynthesis of virulent lipids in mycobacteria and other pharmaceutically or ecologically important polyketides and lipopeptides in other microbes. They do so by bypassing the ubiquitous coenzyme A-dependent activation and rely on the acyl carrier protein-tethered 4'-phosphopantetheine (holo-ACP). The molecular basis of how FAALs strictly reject chemically identical and abundant acceptors like coenzyme A (CoA) and accept holo-ACP unlike other members of the ANL superfamily remains elusive. We show that FAALs have plugged the promiscuous canonical CoA-binding pockets and utilize highly selective alternative binding sites. These alternative pockets can distinguish adenosine 3',5'-bisphosphate-containing CoA from holo-ACP and thus FAALs can distinguish between CoA and holo-ACP. These exclusive features helped identify the omnipresence of FAAL-like proteins and their emergence in plants, fungi, and animals with unconventional domain organizations. The universal distribution of FAALs suggests that they are parallelly evolved with FACLs for ensuring a CoA-independent activation and redirection of fatty acids towards lipidic metabolites.

ABSTRACT

INTRODUCTION: The neural underpinnings of health-related quality of life in Parkinson's disease remain unclear. This study was conducted to unravel which motor and non-motor symptoms in Parkinson's disease influence health-related quality of life and reveal neural networks most likely linked to it. METHODS: Comprehensive clinical assessments were conducted for 247 Parkinson's disease patients and image analyses were performed for 181 patients. Clinical scores commonly used to assess various symptoms related to health-related quality of life were investigated. Factor and resting-state functional magnetic resonance imaging analyses were reviewed to reveal health-related quality of life-associated brain networks. RESULTS: The Spearman's rank correlation coefficient for the Parkinson's disease Questionnaire-39 summary index was high in the Activities-specific Balance Confidence Scale, Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale part 2, Freezing of Gait Questionnaire, and Self-reported Autonomic Symptoms in Parkinson's disease. Multiple regression and Random Forest regression analyses indicated that health-related quality of life-associated factors were Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale part 1, Depression Rating Scales, and the above-mentioned scales. The resting-state functional magnetic resonance imaging analysis revealed decreased functional connectivity between the anterior cingulate cortex and right temporo-parietal junction as health-related quality of life worsened. CONCLUSION: Fear of falling, daily living activities, gait freezing, and autonomic dysfunction have notable effects on health-related quality of life in Parkinson's disease. Brain networks consisting of the anterior cingulate cortex and temporo-parietal junction may be associated with the emotion-related and social factors of health-related quality of life in Parkinson's disease.
