Ammonium oxidation from concentrated synthetic wastewater and landfill leachate using partial nitritation in sequencing batch reactor.

Partial nitritation (PN) is a novel treatment for nitrogen removal using aerobic ammonium oxidation with reduced oxygen requirements compared to conventional nitrification. This study evaluated the performance of the PN process and the factors influencing nitrogen removal from landfill leachate. During the reactivation of biomass, the results showed 70% ammonium removal, but only 20% total nitrogen removal. Further analysis showed that low nitrite accumulation and high nitrate production promoted the growth of nitrite-oxidizing bacteria (NOB). The ammonium removal activity after soaking the cultivated biomass in synthetic water and leachate was measured to be 0.57, 0.1, 0.17, and 0.25 g N•g VSS-1•d-1 for synthetic wastewater and leachate soaking for synthetic wastewater, 12 h, 3 days, and 7 days, respectively. The study found abundant ammonium-oxidizing bacteria (AOB) and NOBs in biomass soaked in synthetic wastewater. However, soaking in leachate promoted AOB growth and inhibited NOB growth making leachate suitable for PN. PRACTITIONER POINTS: The study found that with a longer leachate-soaking period for biomass, ammonium removal activity increases, which in turn increases ammonium conversions during the PN process. Ammonium-oxidizing bacteria (AOB) can acclimate to landfill leachate substrate and grow with a longer soaking period. Nitrite-oxidizing bacteria (NOB) were inhibited by landfill leachate substrate, which is beneficial for nitrite accumulation. Anabolized DO can convert nitrite to nitrate rapidly, which results in higher nitrate accumulation compared to nitrite accumulation. Hence, the DO level has to be sufficiently low to prevent nitrite oxidation and nitrate accumulation.

Primary eyecare in paediatrics population (PREPP) - II study: Study of satisfaction of services and barrier for not reporting to the base hospital on referral among pediatric patients treated in six major vision centers of a tertiary eye care facility in Southern India.

PURPOSE: This study was conducted in continuation of Primary Eyecare in Paediatrics Population (PREPP-I) and was aimed to assess parents' satisfaction with pediatric-eye-care services across six vision centers (VCs) of a tertiary eye hospital in Southern India. The barriers among the parents for not attending the base hospital (BH) when referred from these VCs were also evaluated. METHODS: A standard-validated-satisfaction questionnaire (VSQ) was used to assess patient satisfaction. Responses were assessed on a 5-point Likert scale: 0 (very dissatisfied) to 4 (very satisfied) against each response. Responses were expressed as percentages with 0 (very dissatisfied) and 100% (very satisfied). Patients were referred with a form mentioning reasons for referral (urgent/non-urgent). All referrals were evaluated by the principal investigator. In case of failure to report, parents were enquired about the barrier based on the validated barrier questionnaire (VBQ) over a telephonic conversation. RESULTS: All 250 patients of the PREPP-1 study were included in the satisfaction study. Different domains were evaluated using VSQ (accessibility of VC, waiting hours, financial aspects, spectacle dispensing service, and teleophthalmology). The overall satisfaction was 75%. The most common reason for dissatisfaction was the lack of meeting the ophthalmologist in person, followed by waiting time. 58 patients wanted to visit BH to consult a pediatric ophthalmologist in person (23%). For the barrier study, 14 out of 47 referrals did not report and were evaluated using VBQ (knowledge, physical, time, and financial barriers). The majority had a financial barrier (43%), followed by knowledge (28.6%) and time barrier (14%). CONCLUSION: PREPP-II demonstrated that 3/4 th of pediatric patients are happy to be treated at VC with teleophthalmology services. However, a significant percentage want to consult a specialist at BH. One-fourth of total referrals did not report to BH due to financial constraints and a lack of awareness of the child's condition.

The Association Between Oxidative Stress and the Progression of Heart Failure: A Systematic Review.

Chronic heart failure (CHF) is a progressive multifactorial condition where the role of oxidative stress may have implications in the pathogenesis of the disease. Despite growing interest among researchers and clinicians, the limited, unorganized, and divergent findings regarding the association between oxidative stress and the progression of heart failure (HF) have prompted us to conduct this study. Drawing upon the evolving nature of this research domain, this study is one of the first of its kind to present a systematic and comprehensive overview of the existing evidence regarding the role of oxidative stress production in the progression of HF. This study systematically reviews peer-reviewed empirical studies published in English, particularly focusing on the association between oxidative stress and the progression of HF. Parameters, such as publication year, study design, population demographics (size, age, and gender), types of HF, and characterization of markers in the existing studies, were reviewed. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) procedure, a thorough search was conducted on PubMed, Cochrane, Embase, and Sage databases, without any restrictions on the publication dates of articles, which yielded a total of 1,808 records on the association of oxidative stress production with clinical outcomes in HF patients. The analysis of the content of 17 articles offered a robust observation of this phenomenon, providing insights into the levels of oxidative stress, antioxidant markers, and the enzymes involved in the production of reactive oxygen species (ROS), and their association with the progression and severity of HF. The findings highlighted various knowledge gaps and future research priorities are recommended in the areas of interest and unexplored areas.

Using landfill leachate to indicate the chemical and biochemical activities in elevated temperature landfills.

Landfill leachate properties contain important information and can be a unique indicator for the chemical and biochemical activities in landfills. In the recent decade, more landfills are experiencing elevated temperature, causing an imbalance in the decomposition of solid waste and affecting the properties of the landfill leachate. This study analyzes the properties of leachate from two landfills that were experiencing elevated temperature (ETLFs), samples were collected from both elevated temperature impacted and non-impacted areas in each landfill. The accumulation of volatile fatty acids (VFA) in leachates from elevated temperature impacted areas of both landfill sites revealed that methanogenesis was inhibited by the elevated temperature, which was further confirmed by the more acidic pH, higher H/C elemental ratio, and lower degree of aromaticity of the elevated temperature impacted leachates. Also, carbohydrates depletion indicated possible enhancement of hydrolysis and acidogenesis by elevated temperature, which was supported by compositional comparison of isolated acidic species by negative-ion electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICRMS) at 21 T derived from both elevated temperature impacted and non-impacted areas in the same landfill site. Furthermore, leachate organics fractionation showed that leachates not impacted by elevated temperature contain less hydrophilic fraction and more humic fraction than elevated temperature-impacted leachates for both ETLFs.

A video-atlas of levodopa-induced dyskinesia in Parkinson's disease: terminology matters.

Dyskinesia is a common complication of long-term levodopa therapy in patients with Parkinson's disease (PD), which often worsens the quality of life. It is usually dose-dependent and emerges possibly due to pulsatile stimulation of dopamine receptors. Delineating the pattern of dyskinesia is crucial for determining the most effective therapeutic approach, a task that often presents challenges for numerous neurologists. This article comprehensively describes various patterns of dyskinesia in PD patients and features video demonstration of some of the common forms of dyskinesia. We have used a real case scenario as an example to lead the discussion on the phenomenology, distinguishing features, and management of various types of dyskinesia. A comprehensive literature search was conducted in PubMed using "dyskinesia" as a keyword. The prototype case with videos highlights the differentiating features of dyskinesia along with the treatment strategies. A wide range of descriptive rubrics have been used for certain dyskinesia which are described in detail in this article. The newer types of dyskinesia associated with continuous dopaminergic stimulation in patients with advanced PD and their implications have been described. As there are distinct ways of managing various types of dyskinesia, understanding the phenomenology and chronology of dyskinesia is vital for the optimal management of dyskinetic PD patients. We suggest that dyskinesia should be classified broadly into peak-dose dyskinesia (PDD), biphasic dyskinesia (BD), and OFF-period dystonia. The occurrence of low-dose dyskinesia and complex dyskinesia of continuous dopaminergic treatments should be known to specialists and will require additional studies.

Zinc-solubilizing Bacillus spp. in conjunction with chemical fertilizers enhance growth, yield, nutrient content, and zinc biofortification in wheat crop.

Micronutrient deficiency is a serious health issue in resource-poor human populations worldwide, which is responsible for the death of millions of women and underage children in most developing countries. Zinc (Zn) malnutrition in middle- and lower-class families is rampant when daily calorie intake of staple cereals contains extremely low concentrations of micronutrients, especially Zn and Fe. Looking at the importance of the problem, the present investigation aimed to enhance the growth, yield, nutrient status, and biofortification of wheat crop by inoculation of native zinc-solubilizing Bacillus spp. in conjunction with soil-applied fertilizers (NPK) and zinc phosphate in saline soil. In this study, 175 bacterial isolates were recovered from the rhizosphere of wheat grown in the eastern parts of the Indo-Gangetic Plain of India. These isolates were further screened for Zn solubilization potential using sparingly insoluble zinc carbonate (ZnCO3), zinc oxide (ZnO), and zinc phosphate {Zn3(PO4)2} as a source of Zn under in vitro conditions. Of 175 bacterial isolates, 42 were found to solubilize either one or two or all the three insoluble Zn compounds, and subsequently, these isolates were identified based on 16S rRNA gene sequences. Based on zone halo diameter, solubilization efficiency, and amount of solubilized zinc, six potential bacterial strains, i.e., Bacillus altitudinis AJW-3, B. subtilis ABW-30, B. megaterium CHW-22, B. licheniformis MJW-38, Brevibacillus borstelensis CHW-2, and B. xiamenensis BLW-7, were further shortlisted for pot- and field-level evaluation in wheat crop. The results of the present investigation clearly indicated that these inoculants not only increase plant growth but also enhance the yield and yield attributes. Furthermore, bacterial inoculation also enhanced available nutrients and microbial activity in the wheat rhizosphere under pot experiments. It was observed that the application of B. megaterium CHW-22 significantly increased the Zn content in wheat straw and grains along with other nutrients (N, P, K, Fe, Cu, and Mn) followed by B. licheniformis MJW-38 as compared to other inoculants. By and large, similar observations were recorded under field conditions. Interestingly, when comparing the nutrient use efficiency (NUE) of wheat, bacterial inoculants showed their potential in enhancing the NUE in a greater way, which was further confirmed by correlation and principal component analyses. This study apparently provides evidence of Zn biofortification in wheat upon bacterial inoculation in conjunction with chemical fertilizers and zinc phosphate in degraded soil under both nethouse and field conditions.

Acute abducens nerve palsy with acute disseminated encephalomyelitis-like presentation following COVID-19 vaccination.

We report two adult cases of abducens nerve palsy presenting immediately (within weeks) after they received the first dose of Covishield vaccination. Magnetic resonance imaging (MRI) of the brain obtained after the onset of diplopia demonstrated demyelinating changes. The patients had associated systemic symptoms. Post-vaccination demyelination typically known as acute disseminated encephalomyelitis (ADEM) associated with several vaccines is more common in children. Although the mechanism of the nerve palsy remains unclear, it is suspected to be related to the post-vaccine neuroinflammatory syndrome. Cranial nerve palsies and ADEM-like presentations may represent part of the neurologic spectrum following COVID-vaccination in adults, and ophthalmologists should be aware of these sequelae. Although cases of sixth nerve palsy following COVID vaccination are already reported, associated MRI changes have not been reported from India.

Bacterial ACC deaminase: Insights into enzymology, biochemistry, genetics, and potential role in amelioration of environmental stress in crop plants.

Growth and productivity of crop plants worldwide are often adversely affected by anthropogenic and natural stresses. Both biotic and abiotic stresses may impact future food security and sustainability; global climate change will only exacerbate the threat. Nearly all stresses induce ethylene production in plants, which is detrimental to their growth and survival when present at higher concentrations. Consequently, management of ethylene production in plants is becoming an attractive option for countering the stress hormone and its effect on crop yield and productivity. In plants, ACC (1-aminocyclopropane-1-carboxylate) serves as a precursor for ethylene production. Soil microorganisms and root-associated plant growth promoting rhizobacteria (PGPR) that possess ACC deaminase activity regulate growth and development of plants under harsh environmental conditions by limiting ethylene levels in plants; this enzyme is, therefore, often designated as a "stress modulator." TheACC deaminase enzyme, encoded by the AcdS gene, is tightly controlled and regulated depending upon environmental conditions. Gene regulatory components of AcdS are made up of the LRP protein-coding regulatory gene and other regulatory components that are activated via distinct mechanisms under aerobic and anaerobic conditions. ACC deaminase-positive PGPR strains can intensively promote growth and development of crops being cultivated under abiotic stresses including salt stress, water deficit, waterlogging, temperature extremes, and presence of heavy metals, pesticides and other organic contaminants. Strategies for combating environmental stresses in plants, and improving growth by introducing the acdS gene into crop plants via bacteria, have been investigated. In the recent past, some rapid methods and cutting-edge technologies based on molecular biotechnology and omics approaches involving proteomics, transcriptomics, metagenomics, and next generation sequencing (NGS) have been proposed to reveal the variety and potential of ACC deaminase-producing PGPR that thrive under external stresses. Multiple stress-tolerant ACC deaminase-producing PGPR strains have demonstrated great promise in providing plant resistance/tolerance to various stressors and, therefore, it could be advantageous over other soil/plant microbiome that can flourish under stressed environments.

Arbuscular mycorrhizal fungi-mediated activation of plant defense responses in direct seeded rice (Oryza sativa L.) against root-knot nematode Meloidogyne graminicola.

Rhizosphere is the battlefield of beneficial and harmful (so called phytopathogens) microorganisms. Moreover, these microbial communities are struggling for their existence in the soil and playing key roles in plant growth, mineralization, nutrient cycling and ecosystem functioning. In the last few decades, some consistent pattern have been detected so far that link soil community composition and functions with plant growth and development; however, it has not been studied in detail. AM fungi are model organisms, besides potential role in nutrient cycling; they modulate biochemical pathways directly or indirectly which lead to better plant growth under biotic and abiotic stress conditions. In the present investigations, we have elucidated the AM fungi-mediated activation of plant defense responses against Meloidogyne graminicola causing root-knot disease in direct seeded rice (Oryza sativa L.). The study describes the multifarious effects of Funneliformis mosseae, Rhizophagus fasciculatus, and Rhizophagus intraradices inoculated individually or in combination under glasshouse conditions in rice plants. It was found that F. mosseae, R. fasciculatus and R. intraradices when applied individually or in combination modulated the biochemical and molecular mechanisms in the susceptible and resistant inbred lines of rice. AM inoculation significantly increased various plant growth attributes in plants with simultaneous decrease in the root-knot intensity. Among these, the combined application of F. mosseae, R. fasciculatus, and R. intraradices was found to enhance the accumulation and activities of biomolecules and enzymes related to defense priming as well as antioxidation in the susceptible and resistant inbred lines of rice pre-challenged with M. graminicola. The application of F. mosseae, R. fasciculatus and R. intraradices, induced the key genes involved in plant defense and signaling and it has been demonstrated for the first time. Results of the present investigation advocated that the application of F. mosseae, R. fasciculatus and R. intraradices, particularly a combination of all three, not only helped in the control of root-knot nematodes but also increased plant growth as well as enhances the gene expression in rice. Thus, it proved to be an excellent biocontrol as well as plant growth-promoting agent in rice even when the crop is under biotic stress of the root-knot nematode, M. graminicola.

Evaluation of Osmotolerant Potential of Halomonas sulfidaeris MV-19 Isolated from a Mud Volcano.

Salinity is one of the major challenges for cultivation of crops in a sustainable way because it severely affects plant growth and yield. Keeping this challenge in view, in the current study, a salt-tolerant Halomonas MV-19 was isolated from an extreme niche of mud volcano of Andaman Nicobar Island, India and identified on the basis of standard morphological, biochemical, and physiological tests and identified as Halomonas sulfidaeris strain MV-19 by 16S rRNA gene sequencing. The bacterium can grow on nutrient agar and nutrient broth supplemented with 3.5 M (≥ 20%) sodium chloride (NaCl). Sugar utilization assay revealed that H. sulfidaeris MV-19 utilizes only three sugars (dextrose, fructose, and mannose) from among twenty four tested sugars. The best growth of H. sulfidaeris MV-19 was observed in nutrient broth supplemented with 8% NaCl. When the broth was supplemented with dextrose, fructose, and mannose, the H. sulfidaeris MV-19 grew maximally in nutrient broth supplemented with 8% NaCl and 5% fructose. This strain produced exopolysaccharides (EPS) in nutrient broth supplemented with 8% NaCl and sugars (dextrose, fructose, and mannose). The EPS production was increased by 350% (three and half time) after addition of 5% fructose in nutrient broth compare with the EPS production in nutrient broth without supplemented with sugars. H. sulfidaeris MV-19 strain can produce EPS, which can help aggregate soil particle and reduced osmotic potential in soil, thus, be useful in alleviation of salinity stress in different crops cultivated in saline soils. The findings of the current investigation are expected to contribute towards effective abiotic stress management.

Rates of Fellow Eye Macular Hole Development During Long Term Follow-Up.

Purpose: Identify the long-term rate of fellow eye full-thickness macular hole (FTMH) development. Patients and Methods: In this single site, single provider retrospective consecutive case series, idiopathic FTMH patients who underwent surgery from 2003 to 2014 who also had at least 5 years of follow-up information within our electronic medical record (EMR) which was started in 2014 were identified. Cases with secondary causes (ie, trauma), high myopia, bilateral FTMH on presentation, previous retinal surgery, retinal breaks, or intraocular inflammation were excluded. Demographics, medical and ocular history, refractive error, phakic status, best corrected visual acuity, follow-up duration, surgical technique, single operation anatomic success, and reoperations were recorded. Results: The rate of fellow eye FTMH was 2.6% (2/77) at 1 year, 5.2% (4/77) at 3 years, 9.1% (6/66) at 6 years, and 9.1% (7/77) as of final follow up. There were 2 cases by year 1, 2 additional cases by year 3, 2 additional cases by year 6, and 1 additional case reported thereafter. The average follow up was 11.1 ± 4.5 years. There was no significant difference in visual outcomes between primary eyes and fellow eyes. There was no significant difference in gender, age, ocular comorbidities, refractive error, phakic status, and visual acuity between the unilateral and bilateral groups. Conclusion: The rate of FTMH in the fellow eye was low but significant, increased during long-term follow up, and may stabilize after 6 years.

Incidental complex repetitive discharges on needle electromyography.

INTRODUCTION/AIMS: Complex repetitive discharges (CRDs) are spontaneous electromyography (EMG) waveforms often associated with chronic neurogenic or myopathic diseases, but incidentally identified CRDs have also been described. In this study we describe the distribution and possible significance of incidentally seen CRDs in otherwise normal electrodiagnostic studies. METHODS: A retrospective chart review was performed of all patients with CRDs incidentally documented on otherwise normal electrodiagnostic studies at Mayo Clinic from January 2013 through December 2020. Each patient's clinical symptoms, referral reason, electrodiagnostic report, and imaging studies were analyzed using descriptive statistics. RESULTS: Ninety-four patients (86 females; mean age, 62 years; range, 20 to 86 years) and 107 CRDs were studied. The most common neuromuscular reasons for electrodiagnostic referrals included radiculopathy, peripheral neuropathy, and myopathy. Mean symptom duration was 43 months (range, 1 to 312 months). Eighty-five patients had a CRD identified in one muscle (range, in all patients, one to five muscles). CRDs were identified most frequently in tensor fasciae latae (n = 21), biceps brachii (n = 16), and gluteus maximus (n = 9). Of the 58 patients in whom imaging was available, 46 (79%) had abnormalities that corresponded to the myotome in which the CRDs were visualized, most commonly L5 (n = 19) and C6 (n = 12). Of these 46 patients, 28 (61%) were referred for radicular or limb pain. DISCUSSION: CRDs can be incidentally noted on otherwise normal electrodiagnostic studies, most commonly in L5 and C6 myotomes. The mechanism of CRDs in the absence of electrodiagnostic features of axon loss or remodeling is unknown.

Obstetric and Maternal Outcomes After B-Lynch Compression Sutures: A Meta-Analysis.

This review article aimed to determine the obstetric and maternal outcomes after B-Lynch compression sutures to control atonic postpartum hemorrhage (PPH). This meta-analysis was performed after registering the protocol in the PROSPERO database with the registration number CRD42022355358. Two independent reviewers systematically searched electronic databases and search engines (PubMed, Cochrane Library, and Google Scholar) to retrieve published articles from inception to July 2022. The obstetric and maternal outcomes after the B-Lynch compression suture were computed using the random-effects model in pooled proportion with a 95% confidence interval (CI). Meta-regression analysis and subgroup analysis were performed to explain any source of possible heterogeneity. Quality assessment of the included studies was done using Joanna Briggs Institute (JBI) tools which are critical appraisal tools for systematic reviews and meta-analyses. This meta-analysis included a total of 30 studies involving 1,270 subjects. The pooled proportion of B-Lynch suture alone was 91% (95% CI = 82-97%). The combined proportion of B-Lynch suture plus another compression suture was 1% (95% CI = 0-3%), and the pooled proportion of B-Lynch suture plus vessel ligation was 3% (95% CI = 1-6%). The pooled proportions of PPH controlled and hysterectomies were 94% (95% CI = 91-97%, I2 = 65.3%) and 7% (95% CI = 4-10%, I2 = 72.13%), respectively. Therefore, B-Lynch suture (either alone or in combination with other techniques) is a simple and effective measure to control atonic PPH.

Endophytic Bacillus subtilis antagonize soil-borne fungal pathogens and suppress wilt complex disease in chickpea plants (Cicer arietinum L.).

The present study aimed to identify potential endophytic bacteria antagonistic against three soil-borne fungal pathogens, Rhizoctonia solani, Sclerotium rolfsii, and Fusarium oxysporum f.sp. ciceri causing root rot, collar rot, and fungal wilt diseases in chickpea plants, respectively. A total of 255 bacterial endophytes were isolated from the leaves, stems, and roots of seven different crop plants (chickpea, tomato, wheat, berseem, mustard, potato, and green pea). The dual culture-based screening for antifungal properties indicated that three endophytic isolates had strong inhibition (>50%) against all three pathogens tested. Based on morphological, biochemical, and molecular characterization, the selected isolates (TRO4, CLO5, and PLO3) were identified as different strains of Bacillus subtilis. The bacterial endophytes (TRO4 and CLO5) were positive for plant growth promoting (PGP) traits viz., ammonia, siderophore, and indole-3-acetic acid (IAA) production. The bio-efficacy of the endophytes (TRO4, CLO5, and PLO3) was tested by an in planta trial in chickpea pre-challenged with R. solani, S. rolfsii, and F. oxysporum f.sp. ciceri. The B. subtilis strains TRO4 and CLO5 were found to be effective in reducing percent disease incidence (p ≤ 0.05) and enhancing plant growth parameters. The different root parameters viz. root length (mm), surface area (cm2), root diameter (mm), and root volume (cm3) were significantly (p ≤ 0.05) increased in TRO4 and CLO5 inoculated chickpea plants. Confocal Scanning Laser Microscopy showed heavy colonization of bacteria in the roots of endophyte-inoculated chickpea plants. The inoculation of endophytic Bacillus subtilis strains TRO4 and CLO5 in chickpea plants through seed biopriming reduced the accumulation of superoxide, enhanced the plant defense enzymes, and induced the expression of Pathogenesis-Related (PR) genes. Semi-quantitative analysis of defense-related genes showed differential activation of PR genes (60srp and IFR) by endophyte inoculation. The results of the present study reveal the antagonistic potential of B. subtilis strains TRO4 and CLO5 against three major soil-borne fungal pathogens and their ability to suppress wilt complex disease in chickpea plants. This is the first report on the simultaneous suppression of three major soil-borne fungal pathogens causing wilt complex in chickpea plants by endophytic B. subtilis strains.

Critical Appraisal of Drug Promotional Literature in Accordance With WHO Guidelines.

Background Drug promotional literature (DPL) is used as a marketing tactic to publicize the introduction of new medications. As drug companies are promoting the literature for their brand products, bias is possible. Various studies have demonstrated that printed DPLs disseminated by pharmaceutical companies are typically skewed. Material and method A prospective, observational study was carried out in the outpatient departments of a tertiary care hospital to analyze the DPL of different pharmaceutical companies using WHO criteria for "Ethical criteria for medicinal drug promotion, 1988". Results Out of 192 DPLs analyzed, information regarding the generic name, brand name, amount of active ingredient, and manufacturer name was found in all the DPLs (100%). Though therapeutic uses were mentioned in 91% of DPLs, dosage schedule (regimen) was mentioned only in 60%. Drug safety information such as the side effects and significant adverse drug reactions, precautions and warnings, contraindications, and major drug interactions were present in 24%, 36%, and 20%, respectively. Address of the manufacturer and reference to scientific literature were present only in 63% and 53% of DPLs, respectively. References mainly were from journals, present in 71% of DPLs. Most of the claims made in DPLs were regarding efficacy (73%), followed by safety (34%).  Conclusion In our study, not a single DPL fulfilled all the nine WHO criteria. A doctor should rigorously evaluate study findings before prescribing because misleading and incorrect information is now frequently found in this literature.

Novel Insights into Understanding the Molecular Dialogues between Bipolaroxin and the Gα and Gß Subunits of the Wheat Heterotrimeric G-Protein during Host-Pathogen Interaction.

Spot blotch disease of wheat, caused by the fungus Bipolaris sorokiniana (Sacc.) Shoem., produces several toxins which interact with the plants and thereby increase the blightening of the wheat leaves, and Bipolaroxin is one of them. There is an urgent need to decipher the molecular interaction between wheat and the toxin Bipolaroxin for in-depth understanding of host-pathogen interactions. In the present study, we have developed the three-dimensional structure of G-protein alpha subunit from Triticum aestivum. Molecular docking studies were performed using the active site of the modeled G-protein alpha and cryo-EM structure of beta subunit from T. aestivum and 'Bipolaroxin'. The study of protein-ligand interactions revealed that six H-bonds are mainly formed by Glu29, Ser30, Lys32, and Ala177 of G-alpha with Bipolaroxin. In the beta subunit, the residues of the core beta strand domain participate in the ligand interaction where Lys256, Phe306, and Leu352 formed seven H-bonds with the ligand Bipolaroxin. All-atoms molecular dynamics (MD) simulation studies were conducted for G-alpha and -beta subunit and Bipolaroxin complexes to explore the stability, conformational flexibility, and dynamic behavior of the complex system. In planta studies clearly indicated that application of Bipolaroxin significantly impacted the physio-biochemical pathways in wheat and led to the blightening of leaves in susceptible cultivars as compared to resistant ones. Further, it interacted with the Gα and Gß subunits of G-protein, phenylpropanoid, and MAPK pathways, which is clearly supported by the qPCR results. This study gives deeper insights into understanding the molecular dialogues between Bipolaroxin and the Gα and Gß subunits of the wheat heterotrimeric G-protein during host-pathogen interaction.

Evaluation of the Antinociceptive Action of Simvastatin in Mice.

INTRODUCTION: Statins are well-established agents for dyslipidemia and have successfully been used for the prevention of coronary artery diseases for a long time; this is attributed not only to their lipid-lowering action but also to their pleiotropic actions. Recently many pleiotropic actions of statins have been explored, but very few studies were done to explore statins' antinociceptive action; therefore, the current study was planned to evaluate the antinociceptive activity of Simvastatin in different pain models in mice. MATERIALS AND METHODS: Antinociceptive activity of Simvastatin was evaluated by using Eddy's hot plate method (central analgesic model), acetic acid-induced writhing method (peripheral analgesic model), and biphasic formalin-induced paw licking method. Twenty-four mice were divided into four groups (n = 6 in each): Vehicle control group, simvastatin 5mg/kg, simvastatin 20mg/kg, and positive control group. RESULTS: In the hot plate method, as compared to the vehicle control group, Simvastatin 20mg/kg group showed a significant rise in the reaction time to the corresponding time interval (p<0.001). While the simvastatin 5mg/kg group did not show any significant analgesic activity in the hot plate test. In the acetic acid writhing method, both test groups show a significant delay in the onset of writhing and a decrease in the number of writhes as compared to the vehicle control group (P<0.001). While in the formalin test, both groups show dose-dependent analgesic activity in both the early and late phases. CONCLUSION: Simvastatin exhibits analgesic activity in both central as well as peripheral models of analgesia, but central analgesia shows only at higher concentrations. Similarly, it inhibits inflammatory pain more predominantly than neurogenic, and hence simvastatin can be used in inflammatory conditions like rheumatoid arthritis and osteoarthritis particularly when there is coexisting dyslipidemia.
