OBJECTIVE The aim of this study was to confirm the incidence and implications of a lymphatic spread pattern involving para-aortic lymph node (PAN) metastasis in the absence of pelvic lymph node (PLN) metastasis in patients with endometrial cancer. METHODS We carried out a retrospective chart review of 380 patients with endometrial cancer treated by surgery including PLN dissection and PAN dis...
Protected areas are fundamental to biodiversity conservation, but there is growing recognition of the need to extend beyond protected areas to meet the ecological requirements of species at larger scales. Landscape-scale conservation requires an evaluation of management impact on biodiversity under different land-use strategies; this is challenging and there exist few empirical studies. In a co...
Polyacrylonitrile (PAN) membranes with nano-porous surface and high hydrophilicity were fabricated by addition of polyoxyethylene (40) nonylphenyl ether (IGEPAL) as an additive in the casting solution. The membranes were prepared from PAN/IGEPAL/1-Methyl-2-pyrrolidone (NMP) via phase inversion induced by immersion precipitation technique. Pure water was used as coagulation medium. The effects o...
Abstract Aim We studied differences in stage, treatment modality, morbidity and mortality, two week wait referrals (2WW) rate of 2WW cancer diagnosis. Method All to the NHS trust colorectal department were analysed their diagnosis any cancer. Using data extracted from Somerset Cancer Database, we compared CRC patients diagnosed 6 months prior (Pre-PAN) following (PAN) national lockdown on 23/02...
A transmembrane protein gene, c1orf37-dup, was identified as a young gene specific to humans. It was derived from the conserved c1orf37 gene through retroposition after the divergence of human and chimpanzee. This gene has evolved rapidly driven by positive Darwinian selection as evident from a significantly high ratio of non-synonymous substitution rate to synonymous substitution rate (K(a)/K(...
The impact of catastrophic events on hospitals and communities is huge and continues to hinder progress in developing nations and industrialized countries alike. Over the last 10 years, the UN/ISDR has sponsored a series of global conferences to increase awareness of the importance of risk and vulnerability reduction and the need to build disaster resilient communities. In recognition that hosp...
الیاف کربن، ماده ای با خواص منحصر به فرد (نظیر استحکام ویژه و مدول ویژه بسیار بالا) است که مانند تقویت کننده ای در انواع کامپوزیت ها درصنایع مختلف به خصوص صنایع هوا فضایی و نظامی مورد استفاده قرار می گیرد. این الیاف عمدتا از نوع ویژه ای ازالیاف پلی اکریلونیتریل (pan) تولید می شود. مراحل تولید الیاف کربن شامل پایدارسازی اکسیدی دردمای پایین درمحیط هوا وکربونیزاسیون الیافpan پایدار شده در محیط خنث...
