The purpose of this study was to assess the effects of cinnamon on body weight gain, food intake, and serum lipid profiles of albino rats. This study was conducted on 30 healthy male albino rats weighing approximately 130 ± 5 g. The study was divided into the following two experiments: experiment (1), wherein rats were fed a laboratory diet; and experiment (2), wherein rats were fed a high-fat diet. In experiment 1, a total of 15 rats were divided into three groups. Group A (<i>n</i> = 5, untreated control) was fed laboratory diet, Group B (<i>n</i> = 5) was fed laboratory diet and cinnamon powder (2 g/kg body weight), and Group C (<i>n</i> = 5) was fed laboratory diet and cinnamon powder (4 g/kg body weight) for 30 days. In experiment (2), a total of 15 rats were similarly divided into three groups. Group D (<i>n</i> = 5, treated control) was fed laboratory diet plus high-fat diet, Group E (<i>n</i> = 5) was fed cinnamon powder (2 g/kg body weight) mixed with laboratory diet plus high-fat diet, and Group F (<i>n</i> = 5) was fed cinnamon powder (4 g/kg body weight) mixed with laboratory diet plus high-fat diet daily for 30 days.

The screening for dyslipidemia in Palestine is not established in primary health care centers for healthy people. Our study aims to determine the prevalence of dyslipidemia among healthy undiagnosed adult men in Palestine in order to assess the need for screening and preventive programs for dyslipidemia. Materials and Methods A cross-sectional observational study was carried out in 10 secondary schools at Nablus municipality (Palestine) from August 2017 to February 2018. The study included 140 teachers based on sample calculations. The age of participants ranged between 24 and 60 years. A questionnaire was used to collect demographic data about the lifestyle, past medical, and family histories. Serum lipid profile, and fasting blood glucose levels for each participant were measured. Lipoprotein levels were categorized based on the adult treatment panel III criteria. Results The overall prevalence of dyslipidemia among Palestinian men was 66.4%. The most prevalent type of dyslipidemia was hypo HDL (X < 40 mg/dl, 59.3%), followed by hypertriglyceridemia (X ≥ 200 mg/dl, 20%). The prevalence of hyper LDL (X ≥ 160 mg/dl), hypercholesterolemia (X ≥ 240 mg/dl) was 8.5%, and 3.6%, respectively. About 15% of participants had glucose intolerance, and 4.3% had hyperglycemia (undiagnosed). Those with glucose intolerance, 13 (9.2%) have hypo HDL, while 9 (6.42%) have hypertriglyceridemia. On the other hand, out of hyperglycemic patients: 5 (3.5%) had hypo HDL, and 1 (0.7%) had hypertriglyceridemia. Conclusion Around two-thirds of undiagnosed participants had at least one lipid abnormality. None of them were aware of having dyslipidemia. The prevalence of undiagnosed dyslipidemia was higher than the prevalence of undiagnosed glucose intolerance, and diabetes. This suggests that dyslipidemia plays a major role in developing diabetes. Hence, profound efforts should be done to manage and treat those with dyslipidemia, in order to prevent progression to type II diabetes mellitus.","PeriodicalId":16274,"journal":{"name":"Journal of Lipids","volume":"21 1","pages":""},"PeriodicalIF":5.3,"publicationDate":"2019-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78263299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knowledge of prognostic biomarkers may help in the establishment of therapeutic intervention, management, and follow-up of patients. There have been scattered reports of low high-density lipoprotein cholesterol (HDL-C) and increased triglyceride (TG) in SCD patients. In addition, TG levels have been suggested to be elevated in patients with increased endothelial activation. An increased TG level has been associated with haemolysis, vascular dysfunction, and increased prevalence of pulmonary hypertension. Gum Arabic (GA) is an edible, dried, gummy exudate from the acacia Senegal tree. Several studies on GA ingestion have shown reduced plasma cholesterol and low-density lipoprotein (LDL) concentrations in both animals and humans. We investigated GA's therapeutic potential to modulate serum lipids in patients with sickle cell anemia. Methods This study recruited and documented secondary outcomes in 47 patients (aged 5–42 years) carrying hemoglobin SS. The patients received 30 g/day of GA for 12 weeks. Total cholesterol, TG, LDL, and HDL were measured before and after GA intake. Cobas C311 (Roche, Germany) automated chemistry analyser was used for direct determination of the values of the lipid profile. Results GA significantly decreased total cholesterol (TC), TG, and LDL (p = 0.006, 0.04, and 0.02, resp.). GA showed no effect on HDL level. Baseline serum TG and LDL correlated significantly with the hydrogen peroxide (H2O2) level, which is known as an oxidative stress marker (p = 0.003 and 0.04, resp.). None of the lipid profile elements correlated with age. Conclusion Our results revealed that dyslipidemia in sickle cell patients is associated with oxidative stress but not associated with age. The findings showed that GA significantly decreased TC, LDL, and TG levels, revealing a novel effect of GA, which is considered a natural dietary fibre that can modulate lipid profile in patients with sickle cell anemia.

Recently, evidence has emerged of alternate pathways for hormone entry into cells that are dependent on hormone binding proteins. Transthyretin and transthyretin bound T4 are endocytosed by placental trophoblasts through the high-density lipoprotein receptor, Scavenger Receptor Class B Type 1 (SR-B1). High density lipoprotein (HDL) affects the expression and function of SR-B1 in trophoblast cells. SR-B1 is also expressed in hepatocytes and we sought to determine if hepatocyte SR-B1 was involved in transthyretin or transthyretin-T4 uptake and whether uptake was affected by HDL. Transthyretin and transthyretin-T4 uptake by hepatocytes is not dependent on SR-B1. HDL treatment reduced SR-B1 expression. However, pretreatment of hepatocytes with HDL increased uptake of transthyretin-T4. Knockdown of SR-B1 expression using siRNA also increased transthyretin-T4 uptake. Coaddition of HDL to transthyretin uptake experiments blocked both transthyretin and transthyretin-T4 uptake. Hepatocyte uptake of transthyretin-T4 uptake is influenced by, but is not dependent on, SR-B1 expression. HDL also decreases transthyretin-T4 uptake and therefore diet or drugs may interfere with this process. This suggests that multiple lipoprotein receptors may be involved in the regulation of uptake of transthyretin-T4 in a cell-type specific manner. Further study is required to understand this important process.","PeriodicalId":16274,"journal":{"name":"Journal of Lipids","volume":"1 1","pages":""},"PeriodicalIF":5.3,"publicationDate":"2019-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75010076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this comparative study, we recruited 1518 participants, derived a new modified Friedewald's LDL-C (M-LDL-C) equation, evaluated LDL-C by Friedewald's formula (F-LDL-C), Martin's formula (N-LDL-C), Anandaraja's formula (A-LDL-C), and compared them to direct measurement of LDL-C (D-LDL-C).
