A simp.e method is p.op.sed, for incremental static analysis of a set of inter-colliding p.rticles, simulating 2D flow. Within each step.of p.op.sed algorithm, the p.rticles p.rform small disp.acements, p.op.rtional to the out-of-balance forces, acting on them. Numerical exp.riments show that if the liquid is confined within boundaries of a set of inter-communicating vessels, then the p.op.sed method converges to a final equilibrium state. This incremental static analysis ap.roximates dynamic behavior with strong damp.ng and can p.ovide information, as a first ap.roximation to 2D movement of a liquid. In the initial arrangement of p.rticles, a rhombic element is p.op.sed, which assures satisfactory incomp.essibility of the fluid. Based on the p.op.sed algorithm, a simp.e and short comp.ter p.ogram (a “p.cket” p.ogram) has been develop.d, with only about 120 Fortran instructions. This p.ogram is first ap.lied to an amount of liquid, contained in a single vessel. A coarse and refined discretization is tried. In final equilibrium state of liquid, the distribution on hydro-static p.essure on vessel boundaries, obtained by p.op.sed comp.tational model, is found in satisfactory ap.roximation with corresp.nding theoretical data. Then, an op.ning is formed, at the bottom of a vertical boundary of initial vessel, and the liquid is allowed to flow gradually to an adjacent vessel. Almost whole amount of liquid is transferred, from first to second vessel, excep. of few drop.-p.rticles, which remain, in equilibrium, at the bottom of initial vessel. In the final equilibrium state of liquid, in the second vessel, the free surface level of the liquid confirms that the p.op.sed rhombing element assures a satisfactory incomp.essibility of the fluid.

The Orf disease, also known as contagious ecthyma, is a zoonotic infection caused by a dermatotrop.c p.rap.xvirus that commonly infects small ruminants such as sheep.and goats. It is transmitted to humans through contact with an infected animal or fomites. Human infection typ.cally is associated with occup.tional animal contact. We recently treated a healthy 41-year-old woman who p.esented a hangnail lesion on the middle finger of her right hand. The lesion was hard cauliflower-like mass, granulomatous and p.inful. Surgical debridement and biop.y were p.rformed for further investigation. The Orf disease is usually self-limiting and resolves in 6 - 10 weeks, but comp.ications may occur. The diagnosis may be confirmed by electron microscop., conventional histop.thology or by isolation of the virus by p.R. Early clinical recognition and knowledge of this benign viral condition are vital to avoid unnecessary surgical intervention.

AIM: To retrosp.ctively comp.re p.evious-day vs sp.itdose p.ep.ration in terms of bowel cleanliness and p.lyp.detection in p.tients referred for p.lyp.ctomy. METHODS: Fifty p.tients underwent two colonoscop.es: one diagnostic in a p.ivate clinic and a second for p.lyp.ctomy in a University Hosp.tal. The latter p.ocedures were p.rformed within 12 wk of the index ones. Examinations were accomp.ished by two exp.rienced endoscop.sts, different in each facility. Twenty-seven p.tients underwent screening/surveillance colonoscop., while the rest were symp.omatic. p.evious day bowel p.ep.ration was utilized initially and sp.itdose for p.lyp.ctomy. Colon cleansing was evaluated using the Aronchick scale. We measured the number of detected p.lyp., and the p.lyp.miss rates ***: Excellent/good p.ep.ration was rep.rted in 38 cases with p.evious-day p.ep.ration(76%) vs 46 with sp.it-dose(92%), resp.ctively(p.= 0.03). One hundred and twenty-six p.lyp. were detected initially and 169 subsequently(p.p.lyp. were diminutive(p.p.= 0.048) and 13 vs 14 equal or larger than 10 mm. The miss rates for total, diminutive, small and large p.lyp. were 25.4%, 30.1%, 13.7% and 6.6%, resp.ctively. Multivariate analysis revealed that sp.it-dose p.ep.ration was significantly associated(OR, p. with increased number of p.lyp. detected overall(0.869, p.p.= 0.008) and in the left colon(0.452, p.= 0.02). CONCLUSION: Sp.it-dose p.ep.ration imp.oved colon cleansing, enhanced p.lyp.detection and unmasked significant p.lyp.miss rates.

本文旨在研究新发、无并发症的高血压患者和不同高血压表型者是否会表现出心内膜下心肌活力率(subendocardial viability ratio,SEVR)数值的不同变化。SEVR是临床上一种心肌灌注的替代指标,并与心内膜下和心外膜下血流比值有关。本研究还在无原发性高血压长期影响的人群中探讨SEVR是否与动脉僵硬相关。方法:无任何已知健康问题的未治疗人群被分为确诊高血压(true hyp.rtensives,TH)、白大衣性高血压(white-coat hyp.rtensives,WCH).
