BACKGROUND AND OBJECTIVE: Preeclampsia is a systemic disorder, affecting 2-10% of pregnancies, characterized by a deregulated pro- and anti-angiogenic balance. Semaphorin 3F is an angiogenesis inhibitor. We aimed to investigate whether semaphorin 3F expression is modulated in preeclampsia. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: We performed two observational single center cohort studies between March 2013 and August 2014. In the first we enrolled 110 consecutive women, undergoing an elective cesarean section; in the second we included 150 consecutive women undergoing amniocentesis for routine clinical indications at 16-18 week of gestation...

In ex-situ washing, HCl, EDTA and H2O2 solutions can effectively extract heavy metals in river sediment. Nevertheless they often target different sediment components, possibly transforming metal species into more bioavailable and hence toxic ones. This study, in batch settings, investigated the influences of different types of washing agents (i.e. HCl, EDTA and H2O2) on metal (i.e. Cu and Zn) removal from contaminated river sediment, destroy or dissolution of sediment components, and transformation of metal fractions during chemical washing treatment...

BACKGROUND: Functional dyspepsia (FD) is a common functional gastrointestinal disease, and abdominal pain is one of the main symptoms. The aim of this study was to explore the effects and mechanisms of auricular electro-acupuncture (AEA) on gastric hypersensitivity in a rodent model of FD. METHODS: Ten-day-old pups were gavaged with 0.2 ml of 0.1% iodoacetamide daily for 6 days. AEA at the "stomach" point with different parameters or sham-EA was performed on 8-week-old animals...

Postural control relies on the integration of inputs from the visual, somatosensory and vestibular systems which are frequently impaired in people with Multiple Sclerosis (PwMS). In this situation, examining the Romberg ratio can be useful. This parameter can be interpreted as a gross indicator of a vestibular and proprioceptive contribution to postural control. Therefore, the primary objective of the current study was to examine whether the Romberg ratio differs between MS fallers, non-fallers and neurological disability levels...

CONTEXT: Traditional medical education is shifting to incorporate learning technologies and online educational activities with traditional face-to-face clinical instruction to engage students, especially at remote clinical training sites. OBJECTIVE: To describe and evaluate the effectiveness of the blended learning format (combining online and face-to-face instruction) for third-year osteopathic medical students during their pediatric rotation. METHODS: Third-year medical students who completed the 4-week clerkship in pediatrics during the 2014-2015 academic year were divided into a standard learning group and a blended learning group with online activities (discussion boards, blogs, virtual patient encounters, narrated video presentations, and online training modules)...

It is suggested that exercisers engage in a process of teleoanticipation and create an exercise template based upon previous experience with the exercise task which guides their perceptions of the amount of effort required for task completion. The present study examined how altering workload intensity during a positive-pressure treadmill task may impact ratings of perceived exertion (RPE). In a counter-balanced design, 15 collegiate cross country runners (7 males, 8 females) performed two 25-min runs at a constant velocity while bodyweight (BW) was either increased from 60% to 100% (INC) or decreased from 100% to 60% (DEC) in 5 min increments...

Lymphangiogenesis is a recognized hallmark of inflammatory processes in tissues and organs as diverse as the skin, heart, bowel, and airways. In clinical and animal models wherein the signaling processes of lymphangiogenesis are manipulated, most studies demonstrate that an expanded lymphatic vasculature is necessary for the resolution of inflammation. The fundamental roles that lymphatics play in fluid clearance and immune cell trafficking from the periphery make these results seemingly obvious as a mechanism of alleviating locally inflamed environments: the lymphatics are simply providing a drain...

Background: Selecting the cut-off point for the fecal immunochemical test (FIT) for colorectal cancer (CRC) screening programs is of prime importance. The balance between the test performance for detecting advanced neoplasia and the available colonoscopy resources should be considered. We aimed to identify the optimal cut-off of FIT for advanced neoplasia in order to minimize colonoscopy burden. Methods: We conducted a multi-center study in 6 hospitals from diverse regions of Thailand. Asymptomatic participants, aged 50-75 years, were tested with one-time quantitative FIT (OC-SENSOR, Eiken Chemical Co...

BACKGROUND: Although most of cow's milk (CM) allergic children will outgrow their allergy, the pathomechanism of the natural development of tolerance remains poorly understood. It has been suggested that the balance between milk specific IgE and IgG4 plays a major role. OBJECTIVE: We aimed to investigate differences in IgE and IgG4 antibody binding to cow's milk (CM) epitopes between patients with persistent CM allergy (CMA) and those that naturally became tolerant...

While activation of BAX is required for initiating mitochondria-mediated apoptosis, the underlying mechanisms remain unsettled. We studied conformations of BAX protein using pressure- and temperature-resolved ESR techniques and obtained the thermodynamic properties of the conformations. We show that inactive BAX is structurally heterogeneous and exists in equilibrium between two major populations of the conformations, UM and UM', of which the former is thermodynamically favored at room temperature. An increase in the population of UM', induced by either pressure or point mutations of BAX, renders BAX susceptible to oligomerization, which leads to cell death...

WT1 is a transcription factor which regulates the epithelial-mesenchymal balance during embryonic development and, if mutated, can lead to the formation of Wilms' tumour, the most common paediatric kidney cancer. Its expression has also been reported in several adult tumour types, including breast cancer, and usually correlates with poor outcome. However, published data is inconsistent and the role of WT1 in this malignancy remains unclear. Here we provide a complete study of WT1 expression across different breast cancer subtypes as well as isoform specific expression analysis...

We model a social-encounter network where linked nodes match for reproduction in a manner depending probabilistically on each node's attractiveness. The developed model reveals that increasing either the network's mean degree or the "choosiness" exercised during pair formation increases the strength of positive assortative mating. That is, we note that attractiveness is correlated among mated nodes. Their total number also increases with mean degree and selectivity during pair formation. By iterating over the model's mapping of parents onto offspring across generations, we study the evolution of attractiveness...

INTRODUCTION: Edentulous patients often hope for stable and retentive prostheses. In very unfavorable anatomophysiological circumstances, the implant-retained removable full denture is a simple and reliable option that considerably optimizes the prosthetic balance. We present the case of one of those patients taken in charge in our department. OBSERVATION: A full edentulous 82 years old male patient was referred for a prosthetic rehabilitation. He presented with a negative mandibular crest and a very tonic peri-prosthetic musculature in the anterior region...

Reports on the efficacy and safety of long-term entecavir treatment in chronic hepatitis B (CHB) predominantly genotype B or C are insufficient. This study presents the efficacy and safety of entecavir maleate in Chinese CHB patients. Patients were randomly assigned to receive 48-week treatment with either 0.5mg/day entecavir (group A) or 0.5mg/day entecavir maleate (group B), then all patients received treatment with 0.5mg/day entecavir maleate from week 49. Two hundred and seventy-five patients with CHB (HBeAg-positive: 218) were analyzed, predominantly (98...

During aging, there is a marked decline in the antioxidant capacity of brain tissue, leading to a gradual loss of the antioxidant/oxidant balance, which causes oxidative damage. The effects of Paullinia cupana Mart. extract, which is described as being rich in caffeine and many polyphenol compounds, on the central nervous system have not been extensively investigated. The aim of this study was to therefore investigate the effect of a commercial guarana extract (CGE) on cognitive function, oxidative stress, and brain homeostasis proteins related to cognitive injury and senescence in middle age, male Wistar rats...
