Improving laboratory animal science and welfare requires both new scientific research and insights from research in the humanities and social sciences. Whilst scientific research provides evidence to replace, reduce and refine procedures involving laboratory animals (the '3Rs'), work in the humanities and social sciences can help understand the social, economic and cultural processes that enhance or impede humane ways of knowing and working with laboratory animals. However, communication across these disciplinary perspectives is currently limited, and they design research programmes, generate results, engage users, and seek to influence policy in different ways...

BACKGROUND: The syndrome of transient headache and neurologic deficits with cerebrospinal fluid lymphocytosis (HaNDL) is a self-limited benign disorder of unclear pathogenesis, with diverse clinical manifestations. CASES: We report two unusual presentations of this entity. The first case developed a catastrophic picture, characterized by acute elevation of intracranial pressure, necessitating emergency life support. The second case presented with hyperacute-onset mixed aphasia and facial droop, masquerading as acute ischemia of the middle cerebral artery territory...

PURPOSE: Dalfampridine extended-release (ER) tablets 10 mg BID have been approved for use in improving walking in people with multiple sclerosis (MS). This subgroup analysis evaluated the effects of dalfampridine ER 5 and 10 mg BID on distance walked, as assessed using the 6-minute walk (6MW) test. METHODS: This analysis of data from a randomized, placebo-controlled, double-blind study (N = 430) included only the 153 patients with 6MW data available. Participants (aged 18-70 years) were randomly assigned in a 1:1:1 ratio to receive dalfampridine ER 5 or 10 mg or placebo, BID for 4 weeks...

Low molecular weight glutenin subunits (LMW-GS) play an important role in determining dough properties and breadmaking quality. However, resolution of the currently used methodologies for analyzing LMW-GS is rather low which prevents an efficient use of genetic variations associated with these alleles in wheat breeding. The aim of the current study is to evaluate and develop a rapid, simple, and accurate method to differentiate LMW-GS alleles using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry...

BACKGROUND: Dalfampridine extended-release (ER) tablets, 10 mg twice daily, have been shown to improve walking in people with multiple sclerosis. We evaluated the safety and efficacy of dalfampridine-ER 5 mg compared with 10 mg. METHODS: Patients were randomized to double-blind treatment with twice-daily dalfampridine-ER tablets, 5 mg (n = 144) or 10 mg (n = 143), or placebo (n = 143) for 4 weeks. Primary efficacy endpoint was change from baseline walking speed by the Timed 25-Foot Walk 3 to 4 hours after the last dose...

The fusogenic lipid diacylglycerol is essential for remodeling gamete and zygote nuclear envelopes (NE) during early embryogenesis. It is unclear whether upstream signaling molecules are likewise conserved. Here we demonstrate PLCγ and its activator SFK1, which co-operate during male pronuclear envelope formation, also promote the subsequent male and female pronuclear fusion. PLCγ and SFK1 interact directly at the fusion site leading to PLCγ activation. This is accompanied by a spatially restricted reduction of PtdIns(4,5)P2...

The prevalence of moderate-to-severe sleep problems is significantly higher among people with multiple sclerosis (MS) than in the general population. In 2002, we found a significant relationship between fatigue and disrupted sleep in patients with relapsing-remitting MS (RRMS). The objectives of this study were to determine whether eszopiclone (Lunesta; Sunovion Pharmaceuticals Inc, Marlborough, MA) was superior to placebo in improving sleep among patients with MS-related fatigue and sleep complaints (primary end point); and to assess the impact of improved sleep on daytime fatigue and functioning (secondary end point)...

BACKGROUND: Parasomnia overlap disorder (POD) currently is classified by the International Classification of Sleep Disorders, Second Edition (ICSD-2) as a variant of rapid eye movement (REM) sleep behavior disorder (RBD), and therefore its diagnosis also implies counseling the patients on the increased risk for developing neurodegenerative disorders. POD pathophysiology is not clear to date. METHODS: The authors report 5 cases of POD, review the literature, and analyze previously published cases of POD...

Multiple sclerosis (MS) and migraine headache coexist in many young female patients. Whether this is coincidental or causally linked remains unclear. The presenting symptoms and signs of MS relapse and migraine aura can be similar and should be differentiated by careful history and examination to ensure proper diagnosis and treatment. White matter lesions on magnetic resonance imaging have specific patterns for each entity and also need to be interpreted carefully. Although a clear link has not been established between migraine and MS, numerous studies have been reported assessing risks, prevalence, and causation...

The nuclear envelope (NE) breaks down and reforms during each mitotic cycle. A similar process happens to the sperm NE following fertilisation. The formation of the NE in both these circumstances involves endoplasmic reticulum membranes enveloping the chromatin, but PLCγ-dependent membrane fusion events are also essential. Here we demonstrate the activation of PLCγ by a Src family kinase (SFK1) during NE assembly. We show by time-resolved FRET for the first time the direct in vivo interaction and temporal regulation of PLCγ and SFK1 in sea urchins...

INTRODUCTION: Walking impairment is a clinical hallmark of multiple sclerosis (MS), a chronic neurologic disease characterized by axonal demyelination and dysfunction that results in progressive disability. Until recently, there were no therapies that specifically targeted the axonal dysfunction associated with walking impairment in MS. AREAS COVERED: The purpose of this review is to discuss the unmet need for the treatment of walking impairment in MS patients and to evaluate how a new class of pharmacologic therapies, neurofunctional modifiers, potentially addresses this unmet need...

Herein we measure the effect of four adaptive non-synonymous mutations to the glycerol kinase (glpK) gene on catalytic function and regulation, to identify changes that correlate to increased fitness in glycerol media. The mutations significantly reduce affinity for the allosteric inhibitor fructose-1,6-bisphosphate (FBP) and formation of the tetramer, which are structurally related, in a manner that correlates inversely with imparted fitness during growth on glycerol, which strongly suggests that these enzymatic parameters drive growth improvement...

Helicobacter pylori infection in humans is responsible for the onset of severe gastric disorders and a vaccine would be an improvement over current antibiotic-based treatments. Lipopolysaccharide (LPS; O-chain PS→core→lipid A) is a main H. pylori cell wall component, whose O-chain PS exhibits molecular mimicry and therefore any LPS-based vaccine cannot contain O-chain epitopes. Here, the conjugation of de-lipidated H. pylori O:2 LPS to BSA and its immunogenicity in mice is described. IgG antibodies were observed to recognize the LPSs of representative H...

3-Phosphoinositide-dependent kinase 1 (PDK1) plays a central role in regulating the activity of protein kinases that are essential for signaling; however, how PDK1 itself is regulated is largely unknown. We found that homodimerization of PDK1 is a spatially and temporally regulated mechanism for controlling PDK1 activity. We used Förster resonance energy transfer monitored by fluorescence lifetime imaging microscopy to observe PDK1 homodimerization in live cells. A pleckstrin homology (PH) domain-dependent, basal dimeric association of PDK1 was increased upon cell stimulation with growth factors; this association was prevented by a phosphatidylinositol 3-kinase inhibitor and by a mutation in, or a complete deletion of, the PH domain of PDK1...

A human Campylobacter jejuni infection model provided controlled exposure to assess vaccine efficacy and investigate protective immunity for this important diarrheal pathogen. A well-characterized outbreak strain, C. jejuni 81-176, was investigated using a volunteer experimental infection model to evaluate the dose range and duration of protection. Healthy Campylobacter-seronegative adults received C. jejuni strain 81-176 via oral inoculation of 10(5), 10(7), or 10(9) CFU (5 adults/dose), which was followed by clinical and immunological monitoring...
