An indispensable role for the brain renin-angiotensin system (RAS) has been documented in most experimental animal models of hypertension. To identify the specific efferent pathway activated by the brain RAS that mediates hypertension, we examined the hypothesis that elevated arginine vasopressin (AVP) release is necessary for hypertension in a double-transgenic model of brain-specific RAS hype...
BACKGROUND Macrophage apoptosis and MMP activity contribute to vulnerability of atherosclerotic plaques to rupture. By employing molecular imaging techniques, we investigated if apoptosis and MMP release are interlinked. METHODS Atherosclerosis was produced in rabbits receiving high-cholesterol diet (HC), who underwent dual radionuclide imaging with (99m)Tc-labeled matrix metalloproteinase in...
We examined the relationship between postoperative dietary intake (DI) of geriatric hip fracture (HF) patients and their functional and clinical course until 6 months after hospital discharge. In eighty-eight HF patients ≥ 75 years, postoperative DI was estimated with plate diagrams of main meals over four postoperative days. DI was stratified as >50, >25-50, ≤ 25 % of meals served. Functional ...
The age and growth of the dusky grouper, Epinephelus marginatus, in the Balearic Islands (western Mediterranean) were studied by otolith analysis from a sample of 358 specimens ranging in total length (LT) from 6 6 to 105 6 cm. The specimens came from commercial artisanal and recreational spear fisheries between 1999 and 2003. Otoliths grew asymmetrically throughout the range of LT studied, sho...
بالشک مرکبات، pulvinaria aurantii cockerell (hem.: coccidae)، یکی از آفات مهم مرکبات در مازندران می¬باشد. در این تحقیق در مطالعات صحرایی در گام اول فراوانی نسبی و تنوع گونه¬ای دشمنان طبیعی بالشک مرکبات در منطقه¬ی تنکابن ارزیابی شد. بر اساس نتایج حاصل کفشدوزک cryptolaemus montrouzieri mulsant بیشترین درصد فراوانی نسبی را در بین دشمنان طبیعی این آفت داشت. در گام دوم، تغییرات جمعیت و توزیع فضایی ب...
BACKGROUND Anxiety in patients with chronic obstructive pulmonary disease (COPD) is associated with self-reported disability. The purpose of this study is to determine whether there is an association between anxiety and functional measures, quality of life and dyspnea. METHODS Data from 1828 patients with moderate to severe emphysema enrolled in the National Emphysema Treatment Trial (NETT), ...
Computer linkage of an obstetric register and a psychiatric case register made it possible to investigate the temporal relationship between childbirth and psychiatric contact in a population of 470 000 people over a 12-year period: 54 087 births resulted in 120 psychiatric admissions within 90 days of parturition [corrected]. The 'relative risk' of admission to a psychiatric hospital with a psy...
