OBJECTIVE To investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. METHODS Orchiectomized and ovariectomized rat models are used to investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. A rat vertebral body can be longitudinally divided into central portion, which contain more trabecular bone, and para-endplate port...

Strategies for the use of bio-indicators in the prediction of environmental damage should include mechanistic research. This study involves the relationship between the chemical structure and hemotoxic markers of aniline and its halogenated analogs. Aniline-induced methemoglobinemia, loss of circulating blood cells, blood stability, glutathione depletion and membrane cytoskeletal changes were a...

The object of this paper is to study $(epsilon)$-Lorentzian para-Sasakian manifolds. Some typical identities for the curvature tensor and the Ricci tensor of $(epsilon)$-Lorentzian para-Sasakian manifold are investigated. Further, we study globally $phi$-Ricci symmetric and weakly $phi$-Ricci symmetric $(epsilon)$-Lorentzian para-Sasakian manifolds and obtain interesting results.

As many tools have been created to support linked data consumption and publishing, there is a demand for quality assessment and to verify these data. To make this possible, data about this consumption should be recorded. This paper presents an extension to a framework with the goal to support the recording and publishing of the information about the creation and consumption of linked data, in o...

Objective: The purpose of the present study was to investigate the incidence and risk factors of para-aortic lymph node metastasis in stages IB, IIA and IIB cervical carcinoma and provide the basis for para-aortic lymph node dissection. Method: Four hundred and twenty-three patients with stages IB, IIA and IIB cervical cancer who had undergone radical hysterectomy, pelvic lymphadenectomy, and p...

O método semi-empírico HAM/3, desenvolvido por Lindholm e colaboradores há mais de duas décadas, tem uma deficiência. As energias de excitação calculadas por HAM/3 para estados degenerados são desdobradas. Recentemente foi proposto um método para corrigir esta deficiência. Apresentamos aqui resultados de aplicações deste novo método para algumas moléculas com simetria T d , C 3v e D 3h . O esqu...

ste trabajo presenta una solución para resolver un sistema de ecuaciones lineales por medio del método de Householder, teniendo como base un algoritmo que utiliza en paralelo «n» procesadores, y como medio de comunicación entre los procesadores una interfaz MPI. El Programa que se desarrollo fue escrito para el compilador mpcc (Compilador de C para paso de mensajes de la interfaz MPI), para la ...

PURPOSE Treatment of patients with para-aortic lymph node metastasis from colorectal cancer is controversial. The goal of this study was to investigate the technical feasibility of laparoscopic intrarenal para-aortic lymph node dissection in patients with colorectal cancer and clinically suspected para-aortic lymph node dissection. METHODS The inclusion criteria for the laparoscopic approach ...

Pseudomonas aeruginosa ParA belongs to a large subfamily of Walker-type ATPases acting as partitioning proteins in bacteria. ParA has the ability to both self-associate and interact with its partner ParB. Analysis of the deletion mutants defined the part of the protein involved in dimerization and interactions with ParB. Here, a set of ParA alanine substitution mutants in the region between E67...

A reação bromato-brometo, em meio de ácido perclórico, foi observada numa faixa de acidez até então não estudada. A reação foi acompanhada através da medida da absorvância no ponto isosbéstico para as espécies Br2 e Br3 (λ = 446 nm). Observou-se um comportamento de primeira ordem para o bromato e para o brometo e um comportamento de segunda ordem para o H+, levando à lei de velocidade ν = k[BrO...
