Limited information exists on the incidence and characteristics of invasive group A streptococcal (GAS) infections among residents of long-term care facilities (LTCFs). We reviewed cases of invasive GAS infections occurring among persons > or =65 years of age identified through active, population-based surveillance from 1998 through 2003. We identified 1,762 invasive GAS cases among persons > o...

background patients’ escape from hospital imposes a significant cost to patients as well as the health system. besides, for these patients, exposure to adverse events (such as suicide, self-harm, violence and harm to hospital reputation) are more likely to occur compared to others. the present study aimed to determine the characteristics of the absconding patients in a general hospital through ...

The purpose of this paper is to understand the public demand for government information in China and to find out if citizens’ individual characteristics, such as gender, age, education, income, residence and occupation influence their utilization behavior of government information. A survey is conducted to collect data, and total and partial correlation methods are adopted to analyze the data. ...

This paper examines the influence of household membership and area of residence on individual drinking behaviour using a multilevel modelling approach. The effects are investigated using data from the Health Survey for England (HSE) in which multiple interviews were conducted in the same household. With the use of postal address, the data were organised into a hierarchical structure of individu...

Soil and epikarst play an important role in the hydrological cycle in karst regions. This paper focuses on investigating the seasonal recharge and mean residence time (MRT) of soil water and epikarst water in a small karst catchment of southwest China. The deuterium contents in precipitation, creek, soil baseflow (direct recharge of the saturated soil water to the stream), epikarst spring, and ...

The bioequivalence of three chemically equivalent paracetamol generic Mexican products (500 mg tablets) was evaluated in 12 healthy volunteers using the American innovator product (Tylenol, McNeil, Fort Washington, PA), as the reference. Single oral doses of each product were administered at 1-week intervals using a 4 x 4 Latin square design balanced for the first residual effect. The total amo...

The problems of the first-passage time (FPT) [1, 2] and the residence time (RT) [3] are very important issues in random walk theory. Moreover, several properties of diffusion and transport in disordered systems are based in this concepts. Here, we do not want to present a survey of the enormous literature in the field of mean firstpassage time (MFPT) and mean residence time (MRT) of random walk...

In a study of the timing mechanism of the chaperonin nanomachine we show that the hemicycle time (HCT) is determined by the mean residence time (MRT) of GroES on the cis ring of GroEL. In turn, this is governed by allosteric interactions within the trans ring of GroEL. Ligands that enhance the R (relaxed) state (residual ADP, the product of the previous hemicycle, and K(+)) extend the MRT and t...

In this study, an open, double-blind, randomized, two-period, two-group crossover design was conducted in 14 healthy volunteers to study the bioequivalence of a fixed-dose generic product. After administration of test or reference products to each volunteer, both active ingredients were determined simultaneously in plasma samples using a developed and validated HPLC-UV method, and pharmacokinet...
