background: dietary risk factors constitute some of the leading risk factors for cardiovascular disease in iran. the current study reports the burden of ischemic heart disease (ihd) attributable to a low omega-3 fatty acids intake in iran using the data of the global burden of disease (gbd) study 2010. methods: we used data on iran for the years 1990, 2005, and 2010 derived from the gbd study c...

TOPIC: Lung Cancer TYPE: Medical Student/Resident Case Reports INTRODUCTION: cancer is a common cause of cancer-related death, representing fourth all mortality1. However, initial presentation with parotid gland involvement unusual, particularly tissue diagnosis pulmonary adenocarcinoma2. Review the literature shows small cell lung to be slightly more primary than adenocarcinoma2-4. This case h...

Acute poisoning is a medical emergency situation and requires urgent but adequate medical intervention. The outcome depends on accurate primary care, the correct identification of poison(s) and adequate therapeutic decisions. The present paper reviews the literature concerning the role of analytical toxicology in emergency medicine with particular focus on the last few years. This study is main...

BACKGROUND Policies for timing of cord clamping vary, with early cord clamping generally carried out in the first 60 seconds after birth, whereas later cord clamping usually involves clamping the umbilical cord more than one minute after the birth or when cord pulsation has ceased. The benefits and potential harms of each policy are debated. OBJECTIVES To determine the effects of early cord c...

New ventures that commercialize radical technologies tend to cluster in time. Funding for new ventures also ebbs and flows, often synchronous with significant innovations. We suggest that financial market activity is not purely a response to novel technologies but rather, financial markets drive innovation bubbles. We show that financing risk is inherent to the funding of new ventures, but vari...

We numerically reexamine the scaling behavior of period doublings in fourdimensional volume-preserving maps in order to resolve a discrepancy between numerical results on scaling of the coupling parameter and the approximate renormalization results reported by Mao and Greene [Phys. Rev. A 35, 3911 (1987)]. In order to see the fine structure of period doublings, we extend the simple one-term sca...

This paper aims at showing how the so-called mathematical kinetic theory for active particles can be properly developed to propose a new system biology approach. The investigation begins with an analysis of complexity in biological systems, continues with reviewing a general methodology to reduce complexity and furnishes the mathematical tools to describe the time evolution of such systems by c...

We report five ultra-low viscosity nematic liquid crystal mixtures with birefringence around 0.1, dielectric anisotropy in the range of 3 to 6, and clearing temperature about 80°C. A big advantage of these low viscosity mixtures is low activation energy, which significantly suppresses the rising rate of viscosity at low temperatures. Using our mixture M3 as an example, the response time of a 3-...
