Patients suffering from Spinal Cord Injury (SCI) still have a dismal prognosis. Despite all the efforts developed in this area, currently there are no effective treatments. Therefore, cell therapies have been proposed as a viable alternative to the current treatments employed. Adipose tissue-derived Stem Cells (ASCs) and Olfactory Ensheathing Cells (OECs) have been used with promising results in different models of SCI, namely due to the regenerative properties of the secretome of the first, and the guidance capability of the second...

INTRODUCTION: Worldwide there is a desire to diversify the physiotherapy workforce. However, limited research indicates that some student characteristics linked to under-representation in pre registration physiotherapy education have lower attainment and greater attrition. This study explored the relationship between individual characteristics and success of students in pre registration physiotherapy education within South East England. DESIGN: A retrospective multi site cohort study including pre registration physiotherapy programmes in the South East of England...

Nicotinic acetylcholine receptor (nAChR) signalling regulates neuronal differentiation and synaptogenesis. Here we test the hypothesis that developmental nicotine exposure (DNE) disrupts the development of GABAergic synaptic transmission to hypoglossal motoneurons (XIIMNs). GABAergic spontaneous and miniature inhibitory postsynaptic currents (sIPSC/mIPSC) were recorded from XIIMNs in brainstem slices from control and DNE rat pups of either sex, 1-5 days old, at baseline and following acute stimulation of nAChRs with nicotine...

This study assessed the initial feasibility, acceptability, and efficacy of an intervention aimed at reducing dating violence and sexual risk behavior in a sample of adolescent girls (ages 14-17) with prior exposure to physical dating violence (DV). One hundred and nine girls were randomly assigned to Date SMART (Skills to Manage Aggression in Relationships for Teens) or a Knowledge-only (KO) comparison group. Both intervention arms consisted of six, weekly 2-h sessions and one "booster" session 6 weeks later...

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent of Kaposi's sarcoma (KS). It is endemic in a number of sub-Saharan African countries with infection rate of >50%. The high prevalence of HIV-1 coupled with late presentation of advanced cancer staging make KS the leading cancer in the region with poor prognosis and high mortality. Disease markers and cellular functions associated with KS tumorigenesis remain ill-defined. Several studies have attempted to investigate changes of the gene profile with in vitro infection of monoculture models, which are not likely to reflect the cellular complexity of the in vivo lesion environment...

Active cysteinyl protease Caspase-6 is associated with early Alzheimer and Huntington diseases. Higher entorhinal cortex and hippocampal Caspase-6 levels correlate with lower cognitive performance in aged humans. Caspase-6 induces axonal degeneration in human primary neuron cultures and causes inflammation and neurodegeneration in mouse hippocampus, and age-dependent memory impairment. To assess whether Caspase-6 causes damage to another neuronal system, a transgenic knock-in mouse overexpressing a self-activated form of Caspase-6 five-fold in the striatum, the area affected in Huntington disease, and 2...

Speech and motor deficits are highly prevalent (>70%) in individuals with the 600 kb BP4-BP5 16p11.2 deletion; however, the mechanisms that drive these deficits are unclear, limiting our ability to target interventions and advance treatment. This study examined fundamental aspects of speech motor control in participants with the 16p11.2 deletion. To assess capacity for control of voice, we examined how accurately and quickly subjects changed the pitch of their voice within a trial to correct for a transient perturbation of the pitch of their auditory feedback...

Recently, studies on the relationship between gut dysbiosis and Parkinson's disease (PD) have increased, but whether a specific gut bacterium may cause PD remains unexplored. Here, we report, for the first time, that a specific gut bacterium directly induces PD symptoms and dopaminergic neuronal damage in the mouse brain. We found that the number of Enterobacteriaceae, particularly Proteus mirabilis, markedly and commonly increased in PD mouse models. Administration of P. mirabilis isolated from PD mice significantly induced motor deficits, selectively caused dopaminergic neuronal damage and inflammation in substantia nigra and striatum, and stimulated α-synuclein aggregation in the brain as well as in the colon...

Subcortical regions have a pivotal role in cognitive, affective, and social functions in humans, and the structural and functional abnormalities of the regions have been associated with various psychiatric disorders. Although previous studies focused on the neurocognitive and socio-functional consequences of prefrontal and tempolo-limbic abnormalities in psychiatric disorders, those of subcortical structures remain largely unknown. Recently, MRI volume alterations in subcortical structures in patients with schizophrenia have been replicated in large-scale meta-analytic studies...

The neural basis of speech processing is still a matter of great debate. Phonotactic knowledge-knowledge of the allowable sound combinations in a language-remains particularly understudied. The purpose of this study was to investigate the brain regions crucial to phonotactic knowledge in left-hemisphere stroke survivors. Results were compared to areas in which gray matter anatomy related to phonotactic knowledge in healthy controls. 44 patients with chronic left-hemisphere stroke, and 32 controls performed an English-likeness rating task on 60 auditory non-words of varying phonotactic regularities...

BACKGROUND: Compliance with a gluten-free diet (GFD) is difficult at all ages but particularly for teenagers due to social, cultural, economic, and practical pressures. The multidisciplinary team responsible for the treatment of patients with celiac disease and give support to their parents plays a special role on strengthening GFD and assessing the nutritional and physical health. METHODS: A cross-sectional and retrospective study including patients under 20 years of age, with biopsy-confirmed CD, followed regularly at the Department of Pediatrics, Division of Gastroenterology, Hospital das Clínicas, University of Sao Paulo, School of Medicine, Sao Paulo, Brazil, were surveyed using a questionnaire and serologic test applied between November 2011 and February 2012...

BACKGROUND: Onyx is important embolic material in the endovascular treatment of intracranial dural arteriovenous fistula (DAVF). However, its impact on DAVF occlusion rates, morbidity, mortality, and complication rates is not fully examined. OBJECTIVE: To improve understanding of safety and effectiveness profiles associated with transarterial endovascular treatment using Onyx for intracranial DAVF. METHODS: We analyzed data from our prospective clinical registry and conducted a systematic review of all previous transarterial embolization studies using Onyx published between January 2005 and December 2015 in MEDLINE and EMBASE...

The role of skeletal muscle in the pathophysiology of knee OA is poorly understood. To date, the majority of literature has focused on the association of muscle strength with OA symptoms, disease onset and progression. However, deficits or improvements in skeletal muscle strength do not fully explain the mechanisms behind outcome measures in knee OA, such as pain, function and structural disease. This review aims to summarize components of skeletal muscle, providing a holistic view of skeletal muscle mechanisms that includes muscle function, quality and composition and their interactions...

The presence and degree of specialization between the anterior temporal lobes (ATLs) is a key issue in debates about the neural architecture of semantic memory. Here, we comprehensively assessed multiple aspects of semantic cognition in a large group of postsurgical temporal lobe epilepsy (TLE) patients with left versus right anterior temporal lobectomy (n = 40). Both subgroups showed deficits in expressive and receptive verbal semantic tasks, word and object recognition, naming and recognition of famous faces and perception of faces and emotions...

BACKGROUND: Environmental stressors that encounter in early-life and cause abnormal fetal and/or neonatal development may increase susceptibility to non-communicable diseases such as diabetes. Maternal exposure to ambient fine particulate matter (PM2.5) is associated with various fetal abnormalities, suggesting that it may program offspring's susceptibility to diabetes. In the present study, we therefore examined whether maternal exposure to diesel exhaust PM2.5 (DEP), one of the major sources of ambient PM2...

2-Arachidonoylglycerol (2-AG) is a major modulator of blood flow and platelet aggregation and a potential neuroprotectant. The present study investigated the effects of 2-AG on cerebral blood flow (CBF) in the first critical hours during middle cerebral artery occlusion (MCAO) and on platelet aggregation for the first time in rats. Adult male Sprague Dawley rats (n=30) underwent permanent MCAO under isoflurane anaesthesia and were randomly assigned to receive either 2-AG (6 mgkg-1, i.v.), monoacylglycerol lipase inhibitor JZL184 (10 mgkg-1, i...

We are developing a novel, noninvasive method for measuring the efficiency of pulmonary gas exchange in patients with lung disease. The patient wears an oximeter, and we measure the partial pressures of oxygen and carbon dioxide in inspired and expired gas using miniature analyzers. The arterial PO2 is then calculated from the oximeter reading and the oxygen dissociation curve, using the end-tidal PCO2 to allow for the Bohr effect. This calculation is only accurate when the oxygen saturation is below 94% and therefore these normal subjects breathed 12...

Inflammatory bowel disease (IBD) has a complex pathophysiology with limited treatments. Structural and functional changes in the intestinal lymphatic system have been associated with the disease, with increased risk of IBD occurrence linked to a history of acute intestinal injury. To examine the potential role of the lymphatic system in inflammation recurrence, we evaluated morphological and functional changes in mouse mucosal and mesenteric lymphatic vessels, and within the mesenteric lymph nodes during acute ileitis caused by a 7-day treatment with dextran sodium sulfate (DSS)...

INTRODUCTION: Low birth weight has been an enigma for science over time. There have been many researches on its causes and its effects. Low birth weight is an indicator that predicts the probability of a child surviving. In fact, there is an exponential relationship between weight deficit, gestational age, and perinatal mortality. Multiple logistic regression is one of the most expressive and versatile statistical instruments available for the analysis of data in both clinical and epidemiology settings, as well as in public health...

BACKGROUND AND PURPOSE: Fall-induced injuries and resulting deaths are a serious health problem among older adults. The most common risk factors for falls in older adults are muscle weakness, gait deficiencies, and balance deficits. Patients with end-stage hip osteoarthritis (OA) also have many hip dysfunctions, and these all have the potential to increase the risk of falls. However, the incidence and risk factors for falls in patients with end-stage hip OA remain unclear. The aim of this study was to determine the incidence of falls in women with end-stage hip OA and to identify risk factors for falls in this patient population...
