Alzheimer's disease (AD) is the most common cause of dementia in elderly people. Because of the lack of effective treatments for this illness, research focused on identifying compounds that restore cognition and functional impairments in patients with AD is a very active field. Since its discovery in 1993, the serotonin 5-HT6 receptor has received increasing attention, and a growing number of studies supported 5-HT6 receptor antagonism as a target for improving cognitive dysfunction in AD. This article reviews the rationale behind investigations into the targeting of 5-HT6 receptors as a symptomatic treatment for cognitive and/or behavioral symptoms of AD...

The central purpose of this study was to evaluate the fiber type-specific satellite cell and myonuclear responses of endurance-trained cyclists to a block of intensified training, when supplementing with carbohydrate (CHO) vs. carbohydrate-protein (PRO). In a crossover design, endurance-trained cyclists (n = 8) performed two consecutive training periods, once supplementing with CHO (de facto "control" condition) and the other with PRO. Each training period consisted of 10 days of intensified cycle training (ICT-120% increase in average training duration) followed by 10 days of recovery (RVT-reduced volume training; 33% volume reduction vs...

INTRODUCTION: Up to 50% of the infants delivered after radical vaginal trachelectomy (RVT) are born prematurely. An effective strategy to reduce this number could be the closure of the cervical os (CCO). PATIENTS AND METHODS: Fifteen pregnant patients who had a RVT due to early cervical cancer were included in this prospective case control study. All patients were scheduled for CCO early in the second trimester. CCO was performed in 12 patients. Their data were compared to data from 125 pregnancies after a RVT without CCO...

: Rivaroxaban, a selective inhibitor of active factor X belongs to the group of direct-acting oral anticoagulants (DOAC), more and more often replacing vitamin K antagonists (VKA) in venous thromboembolic disease and nonvalvular atrial fibrillation. Attempts are also being made to use DOAC to treat locally formed intracardiac thrombi, mainly in the left atrium and its appendage, in atrial fibrillation and in heart failure. Rarely diagnosed local right ventricular thrombus (RVT) may be a complication of dilated cardiomyopathy (DCM)...

BACKGROUND: Physiological noise is one of the major confounds for fMRI. A common class of correction methods model noise from peripheral measures, such as ECGs or pneumatic belts. However, physiological noise correction has not emerged as a standard preprocessing step for fMRI data yet due to: (1) the varying data quality of physiological recordings, (2) non-standardized peripheral data formats and (3) the lack of full automatization of processing and modeling physiology, required for large-cohort studies...

Renal Vein Thrombosis (RVT) is a rarely encountered condition. It occurs due to a hypercoagulable state in the body, caused by nephrotic syndrome and membranous nephropathy in the adults. Mode of presentation is variable. In chronic form, it may remain silent for a long time and presenting later with symptoms of pedal oedema, varicocele, proteinuria. In acute state, it manifests as flank pain, nausea or haematuria. We present a case of 25-year-old male, with left sided flank pain, haematuria and nausea for 4 days...

Phytochemicals provide environmentally friendly and relatively inexpensive natural products, which could potentially benefit public health by controlling human norovirus (HuNoV) infection. In this study, 18 different phytochemicals were evaluated for antiviral effects against norovirus using murine norovirus (MNV) as a model for norovirus biology. Among these phytochemicals, curcumin (CCM) was the most potent anti-noroviral phytochemical, followed by resveratrol (RVT). In a cell culture infection model, exposure to CCM or RVT for 3 days reduced infectivity of norovirus by 91% and 80%, respectively...

Reactive oxygen species (ROS) decreases bioavailability of nitric oxide (NO) and impairs NO-dependent relaxations. Like NO, hydrogen sulfide (H2S) is an antioxidant and vasodilator; however, the effect of ROS on H2S-induced relaxations is unknown. Here we investigated whether ROS altered the effect of H2S on vascular tone in mouse aorta and determined whether resveratrol (RVT) protects it via H2S. Pyrogallol induced ROS formation. It also decreased H2S formation and relaxation induced by l-cysteine and in mouse aorta...

AIM: Traumatic brain injury (TBI) is a complex process that increasing evidence has demonstrated that reactive oxygen species contribute to brain injury. Revesterol (RVT), which exhibits significant antioxidant properties, is neuroprotective against excitotoxicity, ischemia, and hypoxia. Our aim was to evaluate the neuroprotective effects of RVT on the hippocampus in a rat model of TBI. MATERIAL AND METHODS: Seven rats were divided into four. A moderate degree of head trauma was induced using Feeney's falling weight technique...

Increased mitochondrial content and respiration have both been reported after exercise training. However, no study has directly compared how different training volumes influence mitochondrial respiration and markers of mitochondrial biogenesis. Ten healthy men performed high-intensity interval cycling during 3 consecutive training phases; 4 wk of normal-volume training (NVT; 3/wk), followed by 20 d of high-volume training (HVT; 2/d) and 2 wk of reduced-volume training (RVT; 5 sessions). Resting biopsy samples (vastus lateralis) were obtained at baseline and after each phase...

In the present study, our aim was to investigate whether the novel highly selective 5-hydroxytryptamine6 (5-HT6) receptor antagonist SLV can ameliorate impairments in cognition and social interaction with potential relevance for both schizophrenia and Alzheimer's disease (AD). SLV sub-chronically - treated Wistar rats reared in isolation showed significantly enhanced prepulse inhibition (PPI) and object recognition performance when compared to vehicle - treated rats. In the isolated rats, also a significant reduction in expression of hippocampal neural cell adhesion molecule polysialylation (NCAM-PSA) was found which was ameliorated following treatment with SLV (30mg/kg)...

Resveratrol (RVT), a polyphenolic component in grapes and red wine, has been known for its cytoprotective actions against several diseases. However, beneficial effects of RVT against early exposure to endocrine disrupting chemicals (EDCs) have not been understood. EDCs are linked to several ovarian diseases such as premature ovarian failure, polycystic ovary syndrome, early menopause and infertility in women. Hexavalent chromium (CrVI) is a heavy metal EDC, and widely used in >50 industries. Environmental contamination with CrVI in the US is rapidly increasing, predisposing the human to several illnesses including cancers and still birth...

We report our experience using catheter-directed thrombectomy/thrombolysis (CDT) to treat a patient with acute renal vein thrombosis (RVT) associated with systemic lupus erythematosus (SLE). A 34-year-old woman presented with persistent left flank pain, and a renal ultrasonography examination revealed an enlarged left kidney. Contrast-enhanced computed tomography confirmed the presence of acute left RVT. Because medical treatment failed to relieve her pain and the renal function was deteriorating, we attempted to salvage the occluded left renal vein using an endovascular approach...
