In conduction, thermal rectification occurs when a material or structure transfers heat asymmetrically. In this work, it is shown that, in the bulk, the necessary condition for thermal rectification is that the thermal conductivity of the material or structure be a function of both space and temperature, and that this function is not separable. Practically, this can be achieved using a composit...

OBJECTIVE To assess the need for emergency care in a tertiary hospital, in the Ophthalmology Emergency Room of the University of the São Paulo Medical School General Hospital. MATERIALS AND METHODS A cross-sectional analytic study of the treatment complexity level was carried out in a readily available sample, n = 574, of patients seen at the Ophthalmology Emergency Room of the University of ...

BACKGROUND Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS) caused by auto-reactive T cells against myelin antigens. T-cell immunoglobulin mucin -3 (TIM-3) is a negative regulator glycoprotein expressed by a range of immune cells, including, Th1 cells, activated CD8+ T cells and in a lower level on Th17 cells. A defect in TIM-3 regulation has been shown in mu...

Delirium deteriorates the quality of life in patients with cancer, but is frequently underdiagnosed and not adequately treated. In this study, we evaluated the occurrence of delirium and its risk factors in patients admitted to the hospital for treatment or palliative care in order to develop a prediction model to identify patients at high risk for delirium. In a period of 1.5 years, we evaluat...

Papillary thyroid carcinoma susceptibility candidate 3 (PTCSC3) is a newly identified non-coding RNA, which is highly thyroid-specific. Dramatic downregulation in thyroid cancers suggests its potential roles in the occurrence and development of thyroid tumors. The present study aimed to investigate the effects of PTCSC3 on the biological features of thyroid cancer cells and to explore its possi...

This December 2010 version of the International AIDS Society-USA (IAS-USA) drug resistance mutations list updates the figures last published in December 2009 (Johnson VA et al, Top HIV Med, 2009;17:138-145). This update includes 9 new mutations- E138G and E138K for etravirine (Haddad M et al, CROI, 2010; Abstract 574, and Vingerhoets J et al, Antivir Ther, 2010;15 [Suppl 2]:A125); E92Q for ralt...
