Microelectromechanical System Resonant Devices: A Guide for Design, Modeling and Testing.

Microelectromechanical systems (MEMSs) are attracting increasing interest from the scientific community for the large variety of possible applications and for the continuous request from the market to improve performances, while keeping small dimensions and reduced costs. To be able to simulate a priori and in real time the dynamic response of resonant devices is then crucial to guide the mechanical design and to support the MEMSs industry. In this work, we propose a simplified modeling procedure able to reproduce the nonlinear dynamics of MEMS resonant devices of arbitrary geometry.

Effect of Wine Wastes Extracts on the Viability and Biofilm Formation of and Strains.

In this work, we intended to inhibit the biofilm synthesis and the metabolism of Gram-positive and Gram-negative bacteria using two highly available wastes (stem and marc) obtained after the manufacturing of Torrontes wine at Cafayate, Argentina. Wine wastes contain a significant amount of bioactive compounds, mainly phenolic compounds, which makes them a potential source of compounds with beneficial properties to human health, as they could inhibit the virulence of pathogenic bacteria or protect the tissue against oxidative stress. Marc and stem extracts of Torrontes wine were evaluated for their ability to inhibit the metabolism and biofilm production of and strains.

A cross-sectional study of the forearm bone mineral density in long-term current users of the injectable contraceptive depot medroxyprogesterone acetate.

Background: One of the well-established effects of the use of depot medroxyprogesterone acetate (DMPA) contraception is on bone mineral density (BMD). However, little evidence assesses the skeletal impact of long-term DMPA use. The objective of this study was to assess BMD on a cohort of women who used DMPA uninterruptedly between 1 and 15 years.

Long-term assessment of forearm bone mineral density in postmenopausal former users of depot medroxyprogesterone acetate.

Background: There are many controversies on the association between depot medroxyprogesterone acetate (DMPA) and bone mineral density (BMD). This study reevaluated BMD in postmenopausal women who had used DMPA as a contraceptive until they reached menopause and compared them with non-users. BMD had previously been measured in these women either at 1 year or 2-3 years after menopause and was reassessed in these women 2 years later.

Prevalence of endometrial cancer and hyperplasia in non-symptomatic overweight and obese women.

Background: Obesity is a public health problem and it is necessary to identify if non-symptomatic obese women must be submitted to endometrial evaluation.

Aims: To determine the prevalence of endometrial hyperplasia and cancer in non-symptomatic overweight or obese women.

Methods: A cross-sectional study was carried out in 193 women submitted to an endometrial biopsy using a Pipelle de Cornier.
