BACKGROUND: Although smoking is known to be associated with cardiovascular diseases, the number of large-scale cohort studies on the association between smoking and atrial fibrillation (AF) is limited and the results obtained are also inconsistent, and even fewer studies have addressed the difference between the male and female genders. The present study was intended to clarify and quantify the association between smoking and the risk of AF in men versus women. METHODS: Using AF- and smoking-related keywords, a comprehensive literature search on PubMed, EMbase and Web of Science was conducted with a time limit until December 2016, which was followed by manual screening, quality assessment and data extraction...

Programming of hypothalamic functions regulating energy homeostasis may play a role in intrauterine growth restriction (IUGR)-induced adulthood obesity. The present study investigated the effects of IUGR on the hypothalamus proteome and metabolome of adult rats submitted to 50% protein-energy restriction throughout pregnancy. Proteomic and metabolomic analyzes were performed by data independent acquisition mass spectrometry and multiple reaction monitoring, respectively. At age 4 months, the restricted rats showed elevated adiposity, increased leptin and signs of insulin resistance...

BACKGROUND: Accurate determination of causes of stillbirth is critical to effective prevention. Autopsy remains the gold standard investigation for stillbirth; however, with low autopsy rates many stillbirths are likely to be 'unexplored' rather than 'unexplained'. AIM: To determine factors associated with autopsy following stillbirth. MATERIALS AND METHODS: Routinely collected population-based data on all singleton stillbirths of at least 400 g birthweight or 20 weeks gestation in Queensland between July 2000 and December 2011 were examined...

BACKGROUND: The early diagnosis of acute myocardial infarction (AMI) in patients with mild elevations of high-sensitivity cardiac troponin (hs-cTn) is a challenge. It is unclear whether copeptin, a marker of endogenous stress, or 1h-hs-cTn changes are better suited to address this important unmet clinical need. METHODS: We prospectively enrolled patients presenting with symptoms suggestive of AMI to the emergency department (ED). Two independent cardiologists adjudicated the final diagnosis...

Most HIV prevention for sexual minority men and men who have sex with men targets risk behaviors (e.g., condom use) and helps <50% of participants. Bolstering resilience might increase HIV prevention's effectiveness. This systematic review identified resilience resources (protective factors) in high-risk, HIV-negative, sexual minority men. We reviewed PsycINFO, PsycARTICLES, MEDLINE, references, and Listservs for studies including sexual minority men with 1+ HIV risk factor (syndemics): childhood sexual abuse, partner abuse, substance abuse, or mental health symptoms...

Glutathione reductase (GSR) is an enzyme that catalyzes the biochemical conversion of oxidized glutathione (GSSG) into the reduced form (GSH). Since the ratio between the two forms of glutathione (GSH/GSSG) is important for the optimal function of GSH to act as an antioxidant against H2O2, the contribution of GSR as an enzymatic regulatory agent to maintain the proper ratio is essential. Abalones are marine mollusks that frequently encounter environmental factors that can trigger the overproduction of reactive oxygen species (ROS) such as H2O2...

Three novel series of chalcone derivatives containing an aminoguanidine or acylhydrazone moiety were designed, synthesized and evaluated in terms of their antibacterial, antifungal and anti-inflammatory activities. Most of the synthesized compounds showed potent inhibitory activity towards various bacteria and one fungus with minimum inhibitory concentrations (MICs) ranging from 1 to 8μg/mL. Compared with our previously reported chalcone derivatives (MICs >64μg/mL), these compounds exhibited improved antibacterial activities (MICs=2μg/mL) against Gram-negative bacterial strains (Escherichia coli 1924 and 1356)...

BACKGROUND: Mycobacterium avium subsp. hominissuis is a common intracellular pathogen that infects patients with HIV/AIDS and cause lung infection in patients with underlying lung pathology. M.avium preferably infects macrophages and uses diverse mechanisms to alter phagosome maturation. Once in the macrophage, the pathogen can alter the host cellular defenses by secreting proteins into the cytosol of host cells, but despite considerable research, only a few secreted effector proteins have been identified...

A low power RF amplifier circuit for ion trap applications is presented and described. The amplifier is based on a class-D half-bridge amplifier with a voltage mirror driver. The RF amplifier is composed of an RF class-D amplifier, an envelope modulator to ramp up the RF voltage during the ion analysis stage, a detector or amplitude demodulation circuit for sensing the output signal amplitude, and a feedback amplifier that linearizes the steady state output of the amplifier. The RF frequency is set by a crystal oscillator and the series resonant circuit is tuned to the oscillator frequency...

OBJECTIVE: Uterine sarcomas are rare, highly aggressive tumors with an unfavorable prognosis. The role of lymphadenectomy (LAD) remains controversial for this particular tumor type. To examine whether LAD can assist in prognosis or clinical benefits for uterine sarcoma patients, we performed a meta-analysis based on published studies. METHODS: We initially identified published studies by searching the PubMed database up to 30 November 2015. Study quality was evaluated systematically using the Newcastle-Ottawa Scale for assessing the quality of studies for inclusion in meta-analyses...
