Evolutionary analyses of the critical core promoter interval support a selective advantage for expanding the length of certain short tandem repeats (STRs) in humans. We recently reported genome-wide data on human core promoter STRs that are "exceptionally long" (≥6-repeats). Near the top of the list, the neuron-specific gene, RIT2, contains one of the longest GA-STRs at 11-repeats. In the present study, we analyzed the evolutionary implications of this STR across species. We also studied this STR in a sample of 2,143 Iranian human subjects that encompassed a number of neuropsychiatric disorders and controls...

Fiix-prothrombin time (Fiix-PT) differs from traditional PT in being affected by reduced factor (F) II or FX only. In the randomized controlled Fiix-trial, patients on warfarin monitored with Fiix-PT (Fiix-warfarin patients) had fewer thromboembolisms (TE), similar major bleeding (MB) and more stable anticoagulation than patients monitored with PT (PT-warfarin patients). In the current Fiix-trial report we analyzed how reduced anticoagulation variability during Fiix-PT monitoring was reflected in patients with TE or bleeding...

Pregnancy represents a time of rapid bodily change, which includes physical proportions, physiology and responsibility. At this context, maternal vitamin D stores have been the objective of extensive scientific research during the last decades, focusing on their potential effects on maternal an neonatal health. A growing body of observational studies indicated that maternal hypovitaminosis D (as defined by maternal 25-hydroxyvitamin D [25(OH)D] levels <20 ng/ml or <50 nmol/l) is a significant risk factor for adverse neonatal outcomes including asthma, multiple sclerosis and other neurological disorders...

BACKGROUND: Statins can reduce reproductive damage induced by obesity or high-fat diet (HFD), but the specific regulatory mechanisms are largely unknown. Since mTOR/p70s6k sinaling promotes spermatogonia proliferation and spermatogenesis, we hypothesized that this pathway will be involved in the protective effects of statin in HFD-induced reproductive dysfunction. METHODS: Male Sprague Dawley rats (3 weeks old) were randomly divided into a control group (standard diet), HFD group, and a fluvastatin group (HFD + fluvastatin at 6mg/kg, once daily by oral gavage)...

BACKGROUND/AIMS: It is well documented that myocardial hypertrophy is associated with low ambient temperature. Atorvastatin (Atv) has been shown to protect against atherosclerosis, cardiac fibrosis, ischemia/reperfusion injury, etc. In this study, we aim to determine whether atorvastatin is effective in the treatment of myocardial hypertrophy induced by cold exposure and to shed light on underlying mechanism. METHODS: The mice aged 4-week were randomized to Control (Ctl) group (raised at room temperature), Cold group (raised at 3-5ºC) and Atv treatment group (raised at 3-5ºC followed by 10mg/kg/day Atv infusion)...

BACKGROUND: Repetitive transcranial magnetic stimulation (rTMS) has been used to improve cognitive function, but the stimulation protocols are variable and the underlying mechanism is unclear. Therefore, we intend to examine whether 5Hz rTMS with 30% maximum output could improve cognitive functions in senescence-accelerated-prone mouse 8 (SAMP8) through changing synaptic plasticity. METHODS: SAMP8 and senescence-accelerated-prone mouse/resistant 1 (SAMR1) (7-month old male) were randomly divided into 3 groups: SMAP8 rTMS group (P8-rTMS), SMAP8 sham-rTMS group (P8-sham), and SAMR1 sham-rTMS group (R1-sham)...

INTRODUCTION: It is unclear whether intensive lowering of blood pressure (BP) at the acute phase of intracerebral haemorrhage (ICH) is beneficial. We performed a meta-analysis of randomised controlled trials (RCTs) to assess whether intensive BP lowering in patients with acute ICH is safe and effective in improving clinical outcomes. METHODS: We searched PubMed, EMBASE and the Cochrane databases for relevant RCTs and calculated pooled OR for 3-month mortality (safety outcome) and 3-month death or dependency (modified Rankin Scale (mRs) ≥3;efficacy outcome), in patients with acute ICH randomised to either intensive BP-lowering or standard BP-lowering treatment protocols...

This study measured the effect of a wearable camera, SenseCam, on older and younger adults' memories of recently experienced everyday events. Participants used SenseCam to prospectively sample events from a typical week, which they recalled two weeks later. Recall was cued by a self-generated title only (control condition), by the title and forward-order SenseCam images, or by the title and random-order SenseCam images. In the control condition, older and younger adults' memories were comparably episodic, but older adults recalled more semantic details...

BACKGROUND: The role of neoadjuvant chemotherapy (NACT) for locoregionally advanced nasopharyngeal carcinoma (NPC) is unclear. We aimed to evaluate the feasibility and efficacy of NACT followed by concurrent chemoradiotherapy (CCRT) versus CCRT alone in locoregionally advanced NPC. METHODS: Patients with stage III-IVB (excluding T3N0-1) NPC were randomly assigned to receive NACT followed by CCRT (investigational arm) or CCRT alone (control arm). Both arms were treated with 80 mg/m(2) cisplatin every 3 weeks concurrently with radiotherapy...

Prolonged sitting may promote leg fluid retention that redistributes to the neck during sleep and contributes to snoring. This could be attenuated by calf activity while sitting. In 16 healthy non-obese subjects we measured leg fluid volume (LFV) below the knees using bioelectrical impedance while sitting for 4hours, snoring using a portable BresoDx™ device, and Mallampati grade. Using a double cross-over study design, subjects were randomized to one of two arms and crossed-over one week later: control arm - no calf exercise while sitting; intervention arm - calf contraction against a pedal resistance while sitting...

INTRODUCTION: Tobacco advertising can create false beliefs about health harms that are reinforced by product design features. Reduced nicotine content (RNC) cigarettes may reduce harm, but research has not addressed advertising influences. This study examined RNC cigarette advertising effects on false harm beliefs, and how these beliefs - along with initial subjective ratings of RNC cigarettes - affect subsequent smoking behaviors. We further explored whether subjective ratings moderate associations between false beliefs and behavior...

In the last two decades, an enormous expansion of evidence has been produced in upper airway research. When writing the first EPOS document in 2005 only 5 RCT per year were performed in the area of CRS, in 2007 this changed to 25 per year and it became even higher in the recent years. Randomized Controlled Trials (RCTs) are the "gold standard" for evaluating treatment outcomes providing information on treatments "efficacy". To make life easier for clinicians, systematic reviews and meta-analysis further condense the available evidence...
