BACKGROUNDThe association between the presence of dyslipidemia and major dietary patterns was examined in an adult Iranian population. STUDY DESIGNA cross-sectional study. METHODSThis cross-sectional ...study was conducted among 4672 adults aged 35-65 yr old based on data from the Mashhad Stroke And Heart Atherosclerotic Disorder (MASHAD) Study initiated in 2010. Anthropometric and blood laboratory measurements were collected for all participants. Dietary intake was assessed using a validated 65-item food frequency questionnaire (FFQ). Dietary patterns were identified using factor analysis. RESULTSThe overall prevalence of dyslipidemia was 88% including elevated total cholesterol (38.9%), triglyceride (35.2%), low-density lipoprotein cholesterol (LDL-C) (35.3%) or decreased level of high-density lipoprotein cholesterol (HDL-C) (68.9%). After adjusting for potential confounding factors, participants with higher scores for a Western pattern with lower physical activity level and educational attainment, and higher current smoking habit, increased the risk of having a raised LDL-C (OR=1.17; 95% CI: 1.02, 1.34; P=0.02). However, there was no significant association between adherence to this dietary pattern and other types of dyslipidemia. There was no significant association between a balanced dietary pattern and dyslipidemia and its components (OR=0.90; 95% CI: 0.68, 1.18; P=0.431). CONCLUSIONDyslipidemia was more prevalent among individuals with higher consumption of a western dietary pattern. A direct association was found between adherence to Western dietary pattern and LDL-C level.

Recently, advances in understanding the etiology of urticaria and updates of diagnostic and therapeutic management guidelines have drawn attention to chronic urticaria (CU) morbidity. The present ...study aimed to evaluate Iranian dermatologists' practice and real life management of CU patients. A total of 35 dermatologists and 443 patients were included in the study. Number of female patients was 321 (72.5%). Mean (standard deviation) age of the study patients was 38 (13) years and the median (inter quartile range) of disease duration was 12 (6–48) months. Severity of patients' symptoms was mild for 32.1%, moderate for 38.7%, severe for 18.8%, and 10.4% of them had no evident signs or symptoms. The most common diagnostic methods were physical examination (96.6%), differential blood count (83.5%), erythrocyte sedimentation rate (77.4%), and C‐reactive protein (62.8%). The number of dermatologists prescribed nonsedating antihistamines (nsAH) in regular dose and high dose mono therapy were 26 (74%) and 6 (17%), respectively. About 66% of dermatologists were familiar with British Association of Dermatologists (BAD) guideline. The most common first‐line treatment for CU by Iranian dermatologists was nonsedating antihistamines in regular or high doses. The real‐life management of patients with CU in Iran was in accordance with the available practice guidelines.
Isothermal titration calorimetry (ITC) was utilized at conditions close to physiological (50 mM HEPES buffer, pH 7.4 and 160 mM NaCl) and at various temperatures of 25, 30, 35 and 40 °C to evaluate ...the thermodynamic parameters, enthalpy and heat capacity changes, and subsequently the unfolding process of apo-human serum tarnsferrin (apo-hTf) in the presence of cetylpyridinium chloride (CPC) as a cationic surfactant. The precise thermograms and heat capacity curves obtained and interpreted in terms of molecular events such as specific and non-specific binding and the unfolding process. The analysis of obtained enthalpograms and heat capacity changes profile showed a distinct extreme region close to CPC/apo-hTf mole ratio of 20 indicated that predominant cooperative unfolding occurs at this mole ratio via a two states mechanism.
