Effect of Continuous Positive Airway Pressure on Blood Pressure in Patients with Resistant Hypertension and Obstructive Sleep Apnea: An Updated Meta-analysis.

Purpose Of Review: The effect of continuous positive airway pressure (CPAP) on resistant hypertension in patients at high risk with obstructive sleep apnea (OSA) needs further investigation. We aimed to determine the effect of CPAP on blood pressure in patients with resistant hypertension and OSA. Databases including PubMed, EMBASE, MEDLINE, the Cochrane Library, and CMB were searched.

Efficacy and safety of remifentanil for analgesia in cesarean delivery.

Background: This study aimed to assess the efficacy and safety of remifentanil as a general anesthetic during cesarean delivery.

Material And Methods: Fifty women with singleton pregnancies undergoing cesarean delivery were randomly divided into intervention and control groups, each group containing 25 subjects. Participants in the intervention group received remifentanil (infused at 2 μg/kg/h), whereas subjects in the control group were given dexmedetomidine (infused at 0.

[In vivo interleukin-10 gene transfer down-regulates myocardial matrix metalloproteinase and myocardial collagen expressions in rats with acute myocardial infarction].

Objective: We investigated the in vivo effects of recombinant adenovirus-associated virus type-2 (AAV-2) mediated interleukin-10 (IL-10) gene transfer on the expression of matrix metalloproteinase (MMP)-2, 9, tissue inhibitor of metalloproteinase (TIMP)-1, collagen type I and type III in a rat acute myocardial infarction model.

Method: Male Sprague-Dawley (SD) rats were randomly divided into three groups (each n = 6): sham operation group, MI/AAV2 group, and MI/AAV2-IL-10 group (10(10) vg/ml x 0.1 ml injection at peri-infarct regions immediately post MI).

Molecular cloning, expression profiling, and yeast complementation of 19 beta-tubulin cDNAs from developing cotton ovules.

Microtubules are a major structural component of the cytoskeleton and participate in cell division, intracellular transport, and cell morphogenesis. In the present study, 795 cotton tubulin expressed sequence tags were analysed and 19 beta-tubulin genes (TUB) cloned from a cotton cDNA library. Among the group, 12 cotton TUBs (GhTUBs) are reported for the first time here.

The ascorbate peroxidase regulated by H(2)O(2) and ethylene is involved in cotton fiber cell elongation by modulating ROS homeostasis.

Ascorbate peroxidase (APX) is a reactive oxygen species (ROSs) scavenging enzyme involved in regulation of intracellular ROS levels by reduction of H(2)O(2) to water using ascorbate as an electron donor. In New Phytologist 2007; 175:462-71, we identified a cotton cytosolic APX1 (GhAPX1) that was significantly accumulated during the fast fiber-cell elongation period, through a proteomics approach. Both the transcript levels of GhAPX1 and the total APX activity were highly induced in response to in vitro applied H(2)O(2) or ethylene.

Saturated very-long-chain fatty acids promote cotton fiber and Arabidopsis cell elongation by activating ethylene biosynthesis.

Fatty acids are essential for membrane biosynthesis in all organisms and serve as signaling molecules in many animals. Here, we found that saturated very-long-chain fatty acids (VLCFAs; C20:0 to C30:0) exogenously applied in ovule culture medium significantly promoted cotton (Gossypium hirsutum) fiber cell elongation, whereas acetochlor (2-chloro-N-[ethoxymethyl]-N-[2-ethyl-6-methyl-phenyl]-acetamide; ACE), which inhibits VLCFA biosynthesis, abolished fiber growth. This inhibition was overcome by lignoceric acid (C24:0).

Genetic and biochemical studies in yeast reveal that the cotton fibre-specific GhCER6 gene functions in fatty acid elongation.

3-ketoacyl-CoA synthase catalyses the initial condensation reaction during fatty acid elongation using malonyl-CoA and long-chain acyl-CoA as substrates. Previously, it was reported that several genes encoding putative cotton 3-ketoacyl-CoA synthases were significantly up-regulated during early cotton fibre development. In this study, GhCER6 cDNA that contains an open reading frame of 1479 bp, encoding a protein of 492 amino acid residues homologous to the Arabidopsis condensing enzyme CER6, was isolated and cloned.
