The growth of ZnO nanotubes and nanosquids is obtained by conventional thermal chemical vapor deposition (CVD) without the use of catalysts or templates. Characterization of these ZnO nanostructures was conducted by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (FESEM), Raman spectroscopy, and photoluminescence (PL). Results indicate that these ZnO nanostructures m...

to report the association of pulp calcification with that of cardiovascular disease (cvd) using digital panoramic dental radiographs.digital panoramic radiographs of patients referred from the angiography department were included if the patient was under 55 years old and had non-restored or minimally restored molars and canines. an oral and maxillofacial radiologist evaluated the images for pul...

Introduction: Extensive research suggests a common hypothesis regarding the protective role of total high-density lipoprotein-cholesterol (HDL-C) against cardiovascular disease (CVD). This hypothesis indicates an inverse relationship between CVD and high HDL-C levels. Various mechanisms, such as reverse cholesterol transport, besides anti-inflammatory and antioxidant functions, indicate HDL-C a...

Background & Aim: Smoking is an important individual risk factor for cardiovascular disease (CVD), which in combination with other risk factors may also increase the risk of cardiovascular conditions. In this study, the effect of CVD risk factors has been investigated on different levels of smoking. Methods: This cross-sectional analysis was performed using the baseline data of Ravansar Non-Co...

Introduction: Extreme weather or climate, including heat waves and cold waves, is considered a health issue causing adverse effects on health, such as cardiovascular diseases (CVDs), mortality and morbidity. Thus, this systematic review aimed to study the impacts of extreme ambient temperature on cardiovascular outcomes. Material and Methods: This study was carried out based on the Preferred R...

Pathways for homogeneous thermal decomposition of (C2H5)3Ga (TEGa) were followed using in situ Raman spectroscopy measurements in an up-flow, cold-wall CVD reactor. The results of Density Functional Theory (DFT) calculations were used to assign measured Raman bands to the decomposition products (Et)3Ga, (DEGa)2, (Et)GaH–Ga(Et)2 and (Et)GaH–GaH2. The results of this study are consistent with bot...

Background: Every year, eating, exercise, work, and travel patterns change during the holidays and these behavioral changes at a larger scale may cause death due to cardiovascular disease (CVD). Considering the importance of CVD, the present study was conducted for the first time in Iran to determine the differences in the ratio of deaths due to CVD on holidays and working days. Materials an...
