The combination of lower concentrations of antitumor drugs (carboplatin - CARB, doxorubicin - DOX, and methotrexate - MET) with propolis was investigated against canine osteosarcoma (spOS-2) and mesenchymal stem cells (MSC) in vitro. The mechanism of action in the combinations was analyzed. spOS-2 cells were incubated up to 72 h with propolis (50 μg/ml) alone or in combination with CARB (10-400 μmol/l), DOX (0.5-2 μmol/l) or MET (50-200 μmol/l). Cell viability was assessed by MTT assay, apoptosis/necrosis by flow cytometry, and MSC was incubated with the optimum combination...

Exploring the regulatory mechanism played by endogenous rice miRNAs in defense responses against the blast disease is of great significance in both resistant variety breeding and disease control management. We identified rice defense-related miRNAs by comparing rice miRNA expression patterns before and after Magnaporthe oryzae strain Guy11 infection. We discovered that osa-miR164a expression reduced upon Guy11 infection at both early and late stages, which was perfectly associated with the induced expression of its target gene, OsNAC60...

RATIONALE Obstructive sleep apnea (OSA) patients unable to tolerate standard treatments have few alternatives. They may benefit from weight loss, but the major symptom of daytime performance impairment may remain during weight loss programs. OBJECTIVES We hypothesized that wakefulness-promoter armodafinil would improve driving task performance over placebo in patients undergoing weight loss. METHODS Placebo-controlled, double-blind, randomized trial of Armodafinil vs Placebo daily for 6 months in patients who were also randomized to one of two diets for six months with follow-up at one year in overweight, adult, OSA patients who had rejected standard treatment and suffered daytime sleepiness...

Sung Dong Kim, Kyu Sup Cho
Obstructive sleep apnea (OSA) is a common disorder characterized by intermittent hypoxia and sleep fragmentation. OSA in middle-aged men is often associated with decreased testosterone secretion, together with obesity and aging. Although OSA treatment does not reliably increase testosterone levels in most studies, OSA treatment with testosterone replacement therapy (TRT) may not only improve hypogonadism, but can also alleviate erectile/sexual dysfunction. However, because TRT may exacerbate OSA in some patients, patients should be asked about OSA symptoms before and after starting TRT...

OBJECTIVES: Erectile dysfunction (ED) is highly prevalent in obstructive sleep apnea (OSA), however, the effect of continuous positive airway pressure (CPAP) therapy on erectile function has not yet been thoroughly investigated in these patients. METHODS: Ninety-four men with severe OSA (ie, with an apnea-hypopnea-index ≥ 30/h of sleep) were prospectively evaluated for the presence and severity of ED before and after 6-12 months of CPAP therapy. The abbreviated version of the International Index of Erectile Function, (the IIEF-5) was used to rate erectile function...

Obstructive sleep apnoea (OSA) is common in the general population, particularly in the elderly. This syndrome is frequently responsible for severe cardiovascular complications. However, the indications for its treatment in the elderly remain controversial. We report the case of a 79-year-old man with severe, undiagnosed OSA who inhaled his fixed dental bridge during sleep. The inhaled foreign body came to rest in the lumen of the left main stem bronchus. The association of obesity with a body mass index of 30kg/m2 , snoring with breathing pauses reported by his partner, nocturia, morning headache and an Epworth score of 11 led to polysomnography which confirmed OSA with an apnoea/hypopnoea index of 53 per hour...

Octenyl succinic anhydride (OSA) modified starch is widely used in food industries. In this study, rice starch (RS) was pretreated by dynamic high-pressure microfluidization (DHPM) and subsequently modified by OSA. The influence of DHPM on OSA modification of rice starch was investigated. Results showed that DHPM pretreatment enhanced the degree of substitution by changing the morphology and crystallinity of rice starch. Compared with the rice starch modified by OSA without DHPM pretreatment (OSA-RS), the DHPM-pretreated OSA starch (DHPM-OSA-RS) presented higher peak viscosity and lower pasting temperature...

INTRODUCTION: Recent studies have suggested that there is a strong relationship between obstructive sleep apnea (OSA) and atrial fibrillation (AF). However, they have not identified whether treating OSA with continuous positive airway pressure (CPAP) might reduce rates of recurrent AF. OBJECTIVE: To investigate the recurrent risk of AF after catheter ablation among patients with OSA who did receive or did nor receive CPAP therapy. METHODS: A systematic review of PubMed, Embase, Medline, Cochrane library, China National Knowledge Infrastructure (CNKI) and Wan-fang databases was conducted to obtain relevant cohort studies and randomized controlled trials (RCTs)...

Obstructive sleep apnea syndrome (OSA) is a common respiratory sleep disorder in children that is believed to adversely affect both quality of life and cognition. The purpose of the present systematic review was to obtain evidence of the impact of OSA on children's cognitive/behavioral abilities from primary studies published in MEDLINE/PubMed, LILACS, SciELO, ISI Web of Science, and PsycINFO databases from 2002 to 2016. Of the 649 articles found, only 34 met the eligibility criteria: studies that evaluated cognition, behavior, and/or academic achievement of children meeting clinical criteria for OSA to compare their data to those of healthy controls or normative data, provided that the samples did not present conditions that might affect cognition/behavior irrespective of OSA...

Objective: The aim of this study is to introduce a method in classifying the REM related OSA (RrOSA) and the potential clinical significance. Method: Two hundred and fifty patients (male: 219) with OSAS diagnosed by polysomnographywere recruited in the study. The RrOSAS was defined as the ratio of AHIs in REM and non REM sleep (R) greater than one. In RrOSAS group, patients were divided into RrOSAS Ⅰa (R>2, NREM_AHI<15), RrOSAS Ⅰb (R>2, NREM_AHI>15), and RrOSAS II (2>R>1) three subtypes...

BACKGROUND: Chronic intermittent hypoxia (CIH), an important basis of the pathogenesis of organ damage induced by obstructive sleep apnea syndrome (OSAS), is associated with myocardial injury, such as left ventricular dysfunction, apoptosis, and oxidative stress. Endogenous hydrogen sulfide (H2 S) plays an important role in maintaining cardiovascular functions. Many studies have demonstrated that exogenous H2 S has protective effects against myocardial injury induced by various cardiovascular diseases, and inhibiting the generation of endogenous H2 S has opposite effects...

Obstructive sleep apnea (OSA) can cause sleep fragmentation and intermittent hypoxemia, which are linked to oxidative stress. White matter changes (WMCs) representing cerebrovascular burden and are at risk factor for oxidative ischemic injury. The current study explores the mutual relationships between OSA and WMCs. We performed a systematic review of electronic databases for clinical studies investigating OSA and WMCs. Random-effects models were used for pooled estimates calculation. A total of 22 studies were included in the meta-analysis...

The so-called "metabolic syndrome" (MS), constitutes a cluster of metabolic and cardiovascular abnormalities, including fasting glucose, blood pressure, triglycerides, high density lipoprotein cholesterol (HDL-C), and waist circumference that arise from insulin resistance. Obstructive sleep apnea (OSA) syndrome is characterized by recurrent episodes of partial or complete obstruction of the upper airway, involving cessation or significant decreased airflow, with intermittent hypoxemia, frequent arousals from sleep and recurrent oxyhemoglobin desaturations that interfere with normal sleep patterns generating difficulty falling asleep, unrefreshing sleep and loud snoring...
