OBJECTIVE To evaluate the in vivo and in vitro performance of a China-made dialysis machine (SWS-4000). METHODS This was a multi-center prospective controlled study consisting of both long-term in vitro evaluations and cross-over in vivo tests in 132 patients. The China-made SWS-4000 dialysis machine was compared with a German-made dialysis machine (Fresenius 4008) with regard to Kt/V values,...
BACKGROUND While endovascular stent placement is the standard of care in most percutaneous coronary and peripheral artery intervention, its role in the salvage of thrombosed and stenotic hemodialysis access remains controversial. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS We compared the effects of stent versus angioplasty on primary patency rates in the treatment of stenotic arterioveno...
Human papillomavirus type 6 (HPV-6) is predominantly associated with benign genital warts whereas HPV-16 and HPV-18 are detected predominantly in carcinomas of the lower genital tract; HPV-6 is found rarely in such carcinomas. Experiments were designed to discriminate between two hypotheses concerning the role of HPV-6 in the genesis of a genital tract carcinoma: (i) the HPV-6 in the carcinoma ...
چکیده: هدف: همودیالیز یکی از درمان های اصلی بیماران مبتلا به نارسایی مزمن کلیه می باشد. اگر همودیالیز انجام شده از کفایت لازم برخوردار نباشد، میزان مرگ و میر بیماران افزایش می یابد. یکی از اقدامات مهم در این زمینه جلوگیری از تشکیل لخته می باشد که به وسیله ی روش تجویز مناسب ضدانعقاد(هپارین) میسر می گردد. بنابراین مطالعه حاضر با هدف تعیین تأثیر هپارینه کردن ست همودیالیز بر میزان کفایت دیالیز در ب...
Materials and methods: The study was designed as a quasiexperiment. Twenty-five patients were enrolled in this study. The patients' mean age was 56.5 ± 13.0 years and median time on HD was 63 months. In the first stage of the study, patients were given a standard meal after the first hour of the treatment. The same study group underwent HD without intradialytic food intake 1 week later. Predial...
In this paper we consider the nonlinear wave equation problem utt −B ` ‖u‖0, ‖ur‖0 ́ (urr + 1 r ur) = f(r, t, u, ur), 0 < r < 1, 0 < t < T, ̨̨ lim r→0+ √ rur(r, t) ̨̨ <∞, ur(1, t) + hu(1, t) = 0, u(r, 0) = e u0(r), ut(r, 0) = e u1(r). To this problem, we associate a linear recursive scheme for which the existence of a local and unique weak solution is proved, in weighted Sobolev using standard compa...
Toll-like receptor (TLR) 13 and TLR2 are the major sensors of Gram-positive bacteria in mice. TLR13 recognizes Sa19, a specific 23S ribosomal (r) RNA-derived fragment and bacterial modification of Sa19 ablates binding to TLR13, and to antibiotics such as erythromycin. Similarly, RNase A-treated Staphylococcus aureus activate human peripheral blood mononuclear cells (PBMCs) only via TLR2, implyi...
