Ultrafast dynamics of fluorene initiated by highly intense laser fields.

We present an investigation of the ultrafast dynamics of the polycyclic aromatic hydrocarbon fluorene initiated by an intense femtosecond near-infrared laser pulse (810 nm) and probed by a weak visible pulse (405 nm). Using a multichannel detection scheme (mass spectra, electron and ion velocity-map imaging), we provide a full disentanglement of the complex dynamics of the vibronically excited parent molecule, its excited ionic states, and fragments. We observed various channels resulting from the strong-field ionization regime. In particular, we observed the formation of the unstable tetracation of fluorene, above-threshold ionization features in the photoelectron spectra, and evidence of ubiquitous secondary fragmentation. We produced a global fit of all observed time-dependent photoelectron and photoion channels. This global fit includes four parent ions extracted from the mass spectra, 15 kinetic-energy-resolved ionic fragments extracted from ion velocity map imaging, and five photoelectron channels obtained from electron velocity map imaging. The fit allowed for the extraction of 60 lifetimes of various metastable photoinduced intermediates.

Pathologic classification of a late-onset peripheral neuropathy in a spontaneous Labrador retriever dog model.

Late-onset peripheral neuropathy (LPN) is a heritable canine neuropathy commonly found in Labrador retrievers and is characterized by laryngeal paralysis and pelvic limb paresis. Our objective was to establish canine LPN as a model for human hereditary peripheral neuropathy by classifying it as either an axonopathy or myelinopathy and evaluating length-dependent degeneration. We conducted a motor nerve conduction study of the sciatic and ulnar nerves, electromyography (EMG) of appendicular and epaxial musculature, and histologic analysis of sciatic and recurrent laryngeal nerves in LPN-affected and control dogs. LPN-affected dogs exhibited significant decreases in compound muscle action potential (CMAP) amplitude, CMAP area, and pelvic limb latencies. However, no differences were found in motor nerve conduction velocity, residual latencies, or CMAP duration. Distal limb musculature showed greater EMG changes in LPN-affected dogs. Histologically, LPN-affected dogs exhibited a reduction in the number of large-diameter axons, especially in distal nerve regions. In conclusion, LPN in Labrador retrievers is a common, spontaneous, length-dependent peripheral axonopathy that is a novel animal model of age-related peripheral neuropathy that could be used for fundamental research and clinical trials.

Pretransplantation coronavirus disease 2019 vaccination requirements: A matched case-control study of factors associated with waitlist inactivation.

Numerous United States transplant centers require solid organ transplantation candidates to be vaccinated against the coronavirus disease of 2019 to be active on the United Network for Organ Sharing waiting list. This study examined characteristics of adult patients on one center's kidney transplantation waiting list whose status was inactivated due to a lack of coronavirus disease 2019 vaccination by July 1, 2022, and who did not subsequently provide proof of vaccination by August 31, 2022 (cases). Patients in the control group were retrospectively matched to patients in the case group in a 4-to-1 fashion according to age, sex, and "active" status on the waiting list. Multivariable logistic regression was performed, with race/ethnicity, primary language, health insurance, education, and Vaccine Equity Metric (VEM, a measure of health equity at the zip code level) quartile as covariates. Results revealed that patients from zip codes in the lowest VEM quartile (odds ratio [OR] 1.89; P = .02) and those insured by governmental payors (Medicare: OR, 2.00; P < .01 and Medicaid: OR, 2.89; P < .01) had higher odds of being inactivated than those from zip codes that make up the highest VEM quartile and those insured by commercial payors, respectively. These findings serve as a cautionary tale regarding universal pretransplantation vaccination requirements, which may raise equity concerns that should be considered upon policy implementation.

Crowdsourcing temporal transcriptomic coronavirus host infection data: Resources, guide, and novel insights.

The emergence of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) reawakened the need to rapidly understand the molecular etiologies, pandemic potential, and prospective treatments of infectious agents. The lack of existing data on SARS-CoV-2 hampered early attempts to treat severe forms of coronavirus disease-2019 (COVID-19) during the pandemic. This study coupled existing transcriptomic data from severe acute respiratory syndrome-related coronavirus 1 (SARS-CoV-1) lung infection animal studies with crowdsourcing statistical approaches to derive temporal meta-signatures of host responses during early viral accumulation and subsequent clearance stages. Unsupervised and supervised machine learning approaches identified top dysregulated genes and potential biomarkers (e.g. CXCL10, BEX2, and ADM). Temporal meta-signatures revealed distinct gene expression programs with biological implications to a series of host responses underlying sustained Cxcl10 expression and Stat signaling. Cell cycle switched from G1/G0 phase genes, early in infection, to a G2/M gene signature during late infection that correlated with the enrichment of DNA damage response and repair genes. The SARS-CoV-1 meta-signatures were shown to closely emulate human SARS-CoV-2 host responses from emerging RNAseq, single cell, and proteomics data with early monocyte-macrophage activation followed by lymphocyte proliferation. The circulatory hormone adrenomedullin was observed as maximally elevated in elderly patients who died from COVID-19. Stage-specific correlations to compounds with potential to treat COVID-19 and future coronavirus infections were in part validated by a subset of twenty-four that are in clinical trials to treat COVID-19. This study represents a roadmap to leverage existing data in the public domain to derive novel molecular and biological insights and potential treatments to emerging human pathogens.

Effective connectivity between deep brain stimulation targets in individuals with treatment-resistant depression.

The therapeutic effect of deep brain stimulation on patients with treatment-resistant depression is strongly dependent on the connectivity of the stimulation region with other regions associated with depression. The aims of this study are to characterize the effective connectivity between the brain regions playing important roles in depression and further investigate the underlying pathophysiological mechanisms of treatment-resistant depression and the mechanisms involving deep brain stimulation. Thirty-three individuals with treatment-resistant depression and 29 healthy control subjects were examined. All subjects underwent resting-state functional MRI scanning. The coupling parameters reflecting the causal interactions among deep brain stimulation targets and medial prefrontal cortex were estimated using spectral dynamic causal modelling. Our results showed that compared to the healthy control subjects, in the left hemisphere of treatment-resistant depression patients, the nucleus accumbens was inhibited by the inferior thalamic peduncle and excited the ventral caudate and the subcallosal cingulate gyrus, which in turn excited the lateral habenula. In the right hemisphere, the lateral habenula inhibited the ventral caudate and the nucleus accumbens, both of which inhibited the inferior thalamic peduncle, which in turn inhibited the cingulate gyrus. The ventral caudate excited the lateral habenula and the cingulate gyrus, which excited the medial prefrontal cortex. Furthermore, these effective connectivity links varied between males and females, and the left and right hemispheres. Our findings suggest that intrinsic excitatory/inhibitory connections between deep brain stimulation targets are impaired in treatment-resistant depression patients, and that these connections are sex dependent and hemispherically lateralized. This knowledge can help to better understand the underlying mechanisms of treatment-resistant depression, and along with tractography, structural imaging, and other relevant clinical information, may assist to determine the appropriate region for deep brain stimulation therapy in each treatment-resistant depression patient.

Predictive approach for post-covid 19 evolution study of the pavement surface deterioration based on visual inspection results.

This study proposes a statistical approach to examine pavement surface deterioration tendencies resulting from the COVID-19 pandemic. The road inspection results, the historical road databases, and the condition analysis make pavement management a major challenge for managers in Morocco as well as around the world. The decrease in traffic, the maintenance stoppages, the difficulties in obtaining field information, all these imperative ingredients are a consequence of the covid-19 pandemic. In this respect, historical analysis, remote monitoring and damage prediction have become increasingly important. In collaboration with the Moroccan National Center for Road Research, this study examines the impact of pandemic-induced lockup on the variation of three important pathologies: pullouts, cracks and potholes, based on the results of a visual inspection and the results of deflection and evenness performed in 2020 on a 50 km long section connecting Meknes and Khemisset cities. First, the reduction of data based on deterioration represented in four levels (A, B, C and D), second, the comparison of the different pathologies before and after the pandemic, the impact of the pandemic on the pavement quality, and finally, a prediction of the progression of the pathology using the linear regression method. This study will help decision makers to take into account pandemics and health failures in their pavement management approaches, and especially to prevent future damage for budget allocation.

[Pilonidal cyst of the scalp following a single minor trauma]. / Kyste pilonidal du scalp secondaire à un traumatisme inaperçu : à propos d'un cas.

The pilonidal cyst is an inflammatory disease occurring when a hair follicle penetrates inside a surgical wound. Uncommon in the scalp region, the pilonidal sinus is typically encountered in the sacrococcygeal regions. A single minor trauma of the scalp can be an inductor factor. The surgical treatment includes one-piece excision of the cyst followed by direct closure. We report a case of a 4-year-old child presenting a pilonidal sinus of the scalp following a single minor trauma.

The kinetic energy of PAH dication and trication dissociation determined by recoil-frame covariance map imaging.

We investigated the dissociation of dications and trications of three polycyclic aromatic hydrocarbons (PAHs), fluorene, phenanthrene, and pyrene. PAHs are a family of molecules ubiquitous in space and involved in much of the chemistry of the interstellar medium. In our experiments, ions are formed by interaction with 30.3 nm extreme ultraviolet (XUV) photons, and their velocity map images are recorded using a PImMS2 multi-mass imaging sensor. Application of recoil-frame covariance analysis allows the total kinetic energy release (TKER) associated with multiple fragmentation channels to be determined to high precision, ranging 1.94-2.60 eV and 2.95-5.29 eV for the dications and trications, respectively. Experimental measurements are supported by Born-Oppenheimer molecular dynamics (BOMD) simulations.

X-linked myotubular myopathy is associated with epigenetic alterations and is ameliorated by HDAC inhibition.

X-linked myotubular myopathy (XLMTM) is a fatal neuromuscular disorder caused by loss of function mutations in MTM1. At present, there are no directed therapies for XLMTM, and incomplete understanding of disease pathomechanisms. To address these knowledge gaps, we performed a drug screen in mtm1 mutant zebrafish and identified four positive hits, including valproic acid, which functions as a potent suppressor of the mtm1 zebrafish phenotype via HDAC inhibition. We translated these findings to a mouse XLMTM model, and showed that valproic acid ameliorates the murine phenotype. These observations led us to interrogate the epigenome in Mtm1 knockout mice; we found increased DNA methylation, which is normalized with valproic acid, and likely mediated through aberrant 1-carbon metabolism. Finally, we made the unexpected observation that XLMTM patients share a distinct DNA methylation signature, suggesting that epigenetic alteration is a conserved disease feature amenable to therapeutic intervention.

Discordant expression of maternal SLE in twin pregnancy with a single fetal AV block: A case report.

There are multiple manifestations in the neonatal period for infants born to mothers with systematic lupus erythematosus (SLE), ranging from cardiac, hematologic and dermatologic abnormalities. Cardiac complications may arise in utero in the form of heart block with a resulting increase in fetal mortality. The fetal conduction system is suspected to be affected by transplacental maternal antibodies, however additional environmental and fetal factors appear to play a role. We describe a rare case of a dichorionic-diamniotic twin pregnancy in which only one twin developed a complete heart block progressing to hydrops fetalis and fetal demise.

A phase 1/2 study of ixazomib in place of bortezomib or carfilzomib in a subsequent line of therapy for patients with multiple myeloma refractory to their last bortezomib or carfilzomib combination regimen.

Identifying effective combination regimens is a high priority in multiple myeloma (MM), as most patients eventually become refractory to their current treatments. In this study, we investigated whether the proteasome inhibitor (PI) ixazomib could delay disease progression among patients who failed regimens containing another PI, bortezomib or carfilzomib. This phase 1/2, multicenter, open-label, nonrandomized study enrolled patients who were refractory to a previous regimen containing bortezomib or carfilzomib. Patients continued the other anti-MM drugs in the regimen at the same doses and frequencies. Patients with combination regimens with unknown maximum tolerated dose (MTD) of ixazomib were enrolled in phase 1, with ixazomib starting at 3 mg and then dose escalated to 4 mg. Patients on regimens with a known ixazomib MTD were enrolled in phase 2. Primary endpoints were overall response rate (ORR), clinical benefit rate (CBR), adverse events (AEs), and determination of maximum tolerated dose (MTD). Of the 46 patients enrolled, 39 were evaluable for efficacy. ORR and CBR were 12.8% and 17.9%, respectively. Ixazomib appeared to be well tolerated as a replacement for carfilzomib and bortezomib, with 23.9% of patients experiencing at least one grade ≥3 serious adverse event (SAE) and 37.0% experiencing at least one grade ≥3 AE. The most common grade ≥3 AEs were hyponatremia (8.7%), anemia (8.7%), dyspnea (8.7%), thrombocytopenia (6.5%), dehydration (4.3%), and pneumonia (4.3%). The results indicate that ixazomib is not an effective replacement for bortezomib or carfilzomib for patients with MM who have previously relapsed on other bortezomib/carfilzomib-containing regimens.

Contribution of altered corticospinal microstructure to gait impairment in children with cerebral palsy.

OBJECTIVE: Corticospinal tract (CST) injury may lead to motor disorders in children with Cerebral Palsy (CP). However, the precise underlying mechanisms are still ambiguous. We aimed to characterize the CST structure and function in children with CP and determine their contributions to balance and gait impairments. METHOD: Twenty-six children with spastic CP participated. Transcranial magnetic stimulation (TMS) and diffusion tensor imaging (DTI) were utilized to characterize CST structure and function. Common clinical measures were used to assess gait speed, endurance and balance, and mobility. RESULTS: CST structure and function were significantly altered in children with CP. Different abnormal patterns of CST structure were identified as either abnormal appearance of brain hemispheres (Group-1) or semi-normal CST appearance (Group-2). We found significant correlations between the DTI parameters of the more affected CST and gait features only in Group-1. CONCLUSION: CST structure and function are abnormal in children with CP and these abnormalities may contribute to balance and gait impairment in some children with CP. SIGNIFICANCE: Our findings may lead to the development of further investigations on the mechanisms underlying gait impairment in children with CP and on decision-making for more effective rehabilitation.

Effective connectivity between emotional and motor brain regions in people with psychogenic nonepileptic seizures (PNES).

OBJECTIVE: To characterize the effective connectivity (EC) between the emotion and motor brain regions in patients with psychogenic nonepileptic seizures (PNES), based on resting-state spectral dynamic causal modeling (spDCM). METHODS: Twenty-three patients with PNES and twenty-five healthy control (HC) subjects underwent resting-state fMRI scanning. The coupling parameters indicating the causal interactions between eight brain regions associated with emotion, executive control, and motion were estimated for both groups, using resting-state fMRI spDCM. RESULTS: Compared to the HC subjects, in patients with PNES: (i) the left insula (INS) and left and right inferior frontal gyri (IFG) are more inhibited by the amygdala (AMYG), anterior cingulate cortex (ACC), and precentral gyrus (PCG); (ii) the left AMYG has greater inhibitory effects on the INS, IFG, dorsolateral prefrontal cortex (DLPFC), PCG, and supplementary motor area (SMA); (iii) the left ACC has more inhibitory effects on the INS and IFG; (iv) the right ACC is more inhibited by the INS and IFG, and has a less inhibitory effect on the SMA and PCG; and (v) the left caudate (CAU) had increased inhibitory effects on the AMYG and IFG and a more excitatory effect on the SMA. CONCLUSION: Our results suggest that in patients with PNES, the emotion-processing regions have inhibitory effects on the executive control areas and motor regions. Our findings may provide further insight into the influence of emotional arousal on functional movements and the underlying mechanisms of involuntary movements during functional seizures. Furthermore, they may suggest that emotion regulation through cognitive behavioral psychotherapies can be a potentially effective treatment modality.

Characterization of brain functional connectivity in treatment-resistant depression.

OBJECTIVE: To characterize the functional connectivity (FC) of target brain regions for deep brain stimulation (DBS) in patients with treatment-resistant depression (TRD), and to evaluate its gender and brain lateralization dependence. METHODS: Thirty-one TRD patients and twenty-nine healthy control (HC) subjects participated. FC of subcallosal cingulate gyrus (SCG), ventral caudate (VCa), nucleus accumbens (NAc), lateral habenula (LHb), and inferior thalamic peduncle (ITP) were evaluated using resting-state fMRI. FC was characterized by calculating the nodal 'degree', a major feature of the graph theory. RESULTS: The degree measures of the left and right VCa, the left LHb, and the left ITP were significantly greater in the TRD than in the HC group. The degree was greater in females with TRD in all these regions except the right LHb. Finally, the left hemisphere was generally more affected by depression and presented significant degrees in LHb and ITP regions of the patients. CONCLUSION: Our findings demonstrate the ability of degree to characterize brain FC and identify the regions with abnormal activities in TRD patients. This implies that the degree may have the potential to be used as an important graph-theoretical feature to further investigate the mechanisms underlying TRD, and consequently along with other diagnostic markers, to assist in the determination of the appropriate target region for DBS treatment in TRD patients.

Synthesis, biological evaluation and molecular docking studies of indeno [1, 2-c] pyrazol derivatives as inhibitors of mitochondrial malate dehydrogenase 2 (MDH2).

Hypoxia inducible factor-1 (HIF-1) is a pivotal transcription factor, which is strongly correlated with the induction of angiogenesis, tumor survival, metastasis, and cell proliferation, making it a pivotal therapeutic target for solid tumor therapeutic agents. Herein, a new series of multi-functional chemical probes were designed including principal groups, viz. adamantyl and indene, at various locations of the parent compound LW6. Molecular docking studies were performed on the designed compounds and their relationship with HIF-1α and malate dehydrogenase 2 (MDH2). Inhibition of MDH2 by our compounds was expected to decrease the NADH level. Indeed, treatment of the breast cancer cell line 4T1 led to a strong reduction of the NADH concentration. The greatest reduction in NADH production in mitochondria was observed with (E)-3-(4-((3r, 5r, 7r)-adamantan-1-yl) phenoxy)-N-(5-(piperidine-1-carbonyl)-1, 4-dihydroindeno [1, 2-c] pyrazol-3-yl) acrylamide (18: IC50 = 59 nM), and has the best inhibitory potential under hypoxic conditions (MCF-7: IC50 = 57 nM). This compound also gave one of the highest docking "higher than the score obtained with LW6 in parallel (-31.63 kcal/mol) in the initial docking runs (PDB Code: 4WLO). Other related compounds with good yields were also synthesized from docking results, and all the synthesized compounds (14, 18, 22, 26, 29, 30) were evaluated in vitro on human adenocarcinoma cell lines.

Sleeve gastrectomy prior to liver transplantation is superior to medical weight loss in reducing posttransplant metabolic complications.

Strategies to optimize the management of obesity-related metabolic complications after liver transplantation (LT) are needed. We examined the effect of pre-LT sleeve gastrectomy (SG), as compared to medical weight loss (MWL), on post-LT outcomes. This is a cohort study of adults (≥18 years) with medically complicated obesity who were eligible for pre-LT SG and underwent LT from January 1, 2006 to June 1, 2016. Logistic regression models evaluated the association of SG on post-LT diabetes and hypertension, defined as new-onset or progressive disease post-LT. Cox regression models evaluated the association of SG on recurrent and de novo nonalcoholic fatty liver disease (NAFLD). Among 70 LT recipients who were eligible for pre-LT SG, 14 (20%) underwent SG and 56 (80%) underwent MWL only. Mean follow-up was 5.2 years post-LT. The SG cohort sustained higher % total body weight loss at 3 years post-LT (28.9% vs. 5.4%, p < .001). In multivariable analyses, SG was associated with significantly lower risk of post-LT diabetes (OR 0.04, 95% CI 0.00-0.41, p = .01), hypertension (OR 0.15, 95% CI 0.04-0.67, p = .01), and recurrent and de novo NAFLD (HR 0.19, 95% CI 0.04-0.91, p = .04). When compared to MWL, SG resulted in sustained weight loss and significantly lower risk of diabetes, hypertension, and recurrent and de novo NAFLD post-LT.

Retrospectively assessed trajectories of PTSD symptoms and their subsequent comorbidities.

BACKGROUND: Dynamic trajectories of psychopathology, such as post-traumatic stress disorder (PTSD) provide a key to understanding human adjustment processes after trauma exposure. Recent studies have suggested more heterogeneous mental health outcomes than the initially identified four adjustment trajectories. To explore this heterogeneity, we investigated the after-trauma adjustment patterns of psychopathology based on retrospective lifetime data. This was first carried out on the PTSD symptoms (PTSS, including no symptoms, few symptoms, partial and full PTSD), and secondly together with their post-trauma comorbidities. METHODS: Data of trauma and the post-trauma mental disorders were collected for a large and randomly selected community sample, resulting in a N = 960 trauma-exposed subsample. Pattern recognition as carried out by latent class analysis (LCA) was implemented on this subsample. LCA was first exploited to identify the potential trajectory patterns of PTSS and next to explore the patterns of mental adjustments when additional post-trauma comorbid disorders, such as anxiety, mood and substance use disorders, were assessed. RESULTS: Four PTSS trajectory patterns were found, namely resilient, chronic, recovered, and delayed onset, consistent with findings from longitudinal PTSD studies. When post-trauma comorbidities were evaluated, other than the trajectory pattern of delayed onset which retained a low comorbidity profile, the other three split respectively and paired up with either low, moderate or high comorbidity profile. CONCLUSIONS: Mental health outcomes after trauma exposure were considerably more complex than the four previously established adjustment trajectories. Here, we uncovered additional and more heterogeneous adjustment patterns comprised of PTSS trajectories and post-trauma comorbidity profiles.

Brain functional connectivity in individuals with psychogenic nonepileptic seizures (PNES): An application of graph theory.

OBJECTIVE: To determine brain functional connectivity (FC), based on the graph theory, in individuals with psychogenic nonepileptic seizures (PNES), in order to better understand the mechanisms underlying this disease. METHODS: Twenty-three patients with PNES and twenty-five healthy control subjects were examined. Alterations in FC within the whole brain were examined using resting-state functional magnetic resonance imaging (MRI). We calculated measures of the nodal degree, a major feature of the graph theory, for all the cortical and subcortical regions in the brain. Pearson correlation was performed to determine the relationship between nodal degree in abnormal brain regions and patient characteristics. RESULTS: The nodal degrees in the right caudate (CAU), left orbital part of the left inferior frontal gyrus (ORBinf), and right paracentral lobule (PCL) were significantly greater (i.e. hyper-connectivity) in individuals with PNES than in healthy control subjects. On the other hand, a lesser nodal degree (i.e. hypo-connectivity) was detected in several other brain regions including the left and right insula (INS), as well as the right putamen (PUT), and right middle occipital gyrus (MOG). CONCLUSION: Our findings suggest that the FC of several major brain regions can be altered in individuals with PNES. Areas with hypo-connectivity may be involved in emotion processing (e.g., INS) and movement regulation (e.g., PUT), whereas areas with hyper-connectivity may play a role in the inhibition of unwanted movements and cognitive processes (e.g., CAU).

Topology predicts long-term functional outcome in early psychosis.

Early intervention in psychosis is crucial to improving patient response to treatment and the functional deficits that critically affect their long-term quality of life. Stratification tools are needed to personalize functional deficit prevention strategies at an early stage. In the present study, we applied topological tools to analyze symptoms of early psychosis patients, and detected a clear stratification of the cohort into three groups. One of the groups had a significantly better psychosocial outcome than the others after a 3-year clinical follow-up. This group was characterized by a metabolic profile indicative of an activated antioxidant response, while that of the groups with poorer outcome was indicative of oxidative stress. We replicated in a second cohort the finding that the three distinct clinical profiles at baseline were associated with distinct outcomes at follow-up, thus validating the predictive value of this new stratification. This approach could assist in personalizing treatment strategies.

Therapeutic effects of robotic rehabilitation on Neural and Muscular Abnormalities associated with the Spastic Ankle in Stroke Survivors.

Spasticity is a common ailment following stroke, which can cause pain, contracture, abnormal limb posture and functional limitation. Early management of post-stroke spasticity is vital to reduce these complications, and improve function and help patients become independent. We propose a therapeutic program based on applying a series of vibrations to the ankle joints at specific ankle position as well as over the range of motion using a rehabilitation robotic system to reduce the neural and muscular abnormalities associated with spasticity. We provided a 30-minute perturbation training, 3 times a week for 10 sessions for 8 stroke survivor subjects. Ankle stiffness was calculated using the hysteresis curves. Other kinematic and kinetic parameters were also used to evaluate the mechanical abnormalities. We evaluated participants before starting the therapeutic program, immediately after first session of training and after 10 sessions of training.Our results showed that all subjects had substantial improvements in stiffness, max voluntary contraction, energy loss, passive range of motion, and voluntary movement after both short- and long-term therapeutic program. Surprisingly, for most of these measures the maximum improvement obtained at short-term training. Interestingly, these improvements became persistent over the long-term training. These findings suggest that vibration therapy can be considered as an effective rehabilitation intervention to reduce neuromuscular abnormalities associated with the spasticity in stroke.
