Introduction. Laparo-endoscopic single-site surgery (LESS) may diminish morbidity of laparoscopic surgery. We prospectively evaluated feasibility and outcomes of LESS-Radical Nephrectomy (LESS-RN) and Partial Nephrectomy (LESS-PN). Methods. 10 patients underwent LESS-RN (6) and LESS-PN (4) between 2/2009-5/2009. LESS-RN included 2 with renal vein thrombectomy, one of which was also cytoreductiv...

To determine the mechanism of the purified protein derivative (PPD)-specific hyporesponsiveness in Mycobacterium bovis BCG-vaccinated human T-cell leukemia virus type 1 (HTLV-1)-infected individuals, we examined cytokine production in response to PPD in the following four groups of individuals: (i) HTLV-negative, PPD nonresponders (n = 11; NN); (ii) HTLV-negative, PPD responders (n = 18; NP); (...

Picralima nitida, aplant of African pharmacopoeia is used in the treatment of diseases such as malaria, typhoid fever and anemia. To promote this herb, we undertook to study its effect on the cardiovascular system and the smooth duodenal muscle.The study of this extract on the electrocardiogram of rabbits at doses of between 2.7×10 g/kg and 3.4×10 g/kg bw, showed that Pn causes an increase of t...

peripheral neuroepitbelioma (pn) is a rare highly malignant tumor, classified in the group of small round cell tumors. we report eight cases of pn, based on histologic appearance and immunohistochemical staining for neuron-specific enolase (nse). electron microscopy was also performed in three cases. the tumors exhibited rapid local growth, leading to limb amputation in five cases. histological...

Zinc finger proteins are associated with hereditary diseases and cancers. To obtain an adequate amount of zinc finger proteins for studying their properties, structure, and functions, many protein expression systems are used. ZNF191(243-368) is a zinc finger protein and can be fused with His-tag to generate fusion proteins such as His6-ZNF191(243-368) and ZNF191(243-368)-His8. The purification ...

The asymmetric unit of the title complex, [Ni(pht)(2)(pn)(2)] (pht is 5,5-diphenyl-hydantoinate and pn is propane-1,2-diamine) or [Ni(C(15)H(11)N(2)O(2))(2)(C(3)H(10)N(2))(2)], contains one-half [Ni(pht)(2)(pn)(2)] mol-ecule. The Ni(II) atom is situated on a crystallographic center of inversion and shows a distorted octa-hedral coordination geometry. A three-dimensional network structure is ass...

BACKGROUND The optimal route of nutrition in severe pancreatitis is controversial. Parenteral nutrition (PN) is preferred, but enteral nutrition (EN) promises to attenuate inflammation and prevent sepsis. We hypothesized that EN was at least equivalent to PN in reducing inflammation, providing effective nutrition and being cost-effective. METHODS We conducted a randomized controlled trial com...

Indirect immunohistochemistry and an androgen receptor antibody. PG-21, was used to characterize rhe onlogeny of cells containing androgen receptor-like immunoreactivity (AR-ir) and the effects of exogenous testosterone administration on AR-ir in the developing Brazilian opossum brain. Cells containing AR-ir were first seen in the anterior pituitary at day 5 of postnatal life (PN). Between 10 a...

Let p be an odd prime, such that pn < p/2 < pn+1, where pn is the n-th prime. We study the following question: with what probability does there exist a prime in the interval (p, 2pn+1)? After the strong definition of the probability with help of the Ramanujan primes ([11], [12])and the introducing pseudo-Ramanujan primes, we show, that if such probability P exists, then P ≥ 0.5. We also study a...
