BACKGROUND The purpose of this study was to assess the feasibility of infrared (IR) spectroscopy for the simultaneous quantification of serum LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) concentrations. METHODS Serum samples (n = 90) were obtained. Duplicate aliquots (5 microL) of the serum specimens were dried onto IR-transparent barium fluoride substrates, and transmission IR spectra...

BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with increased risk of cardiovascular disease. The purpose of this study was to investigate the ef¬fects of omega-3 fatty acids on serum paraoxonase 1 activity and lipids ratios in polycystic ovary syndrome. METHODS This double-blind randomized controlled clinical trial was conducted on 64 PCOS pa¬tients wit...

AIMS The aim of this study is to determine whether influences of drinking alcohol on serum lipid levels are different in smokers and non-smokers. METHODS Subjects were 25,689 healthy male workers aged 40 to 59 years. Serum total and HDL cholesterol and triglyceride concentrations were measured and LDL cholesterol concentrations were estimated by using the Friedewald formula. The subjects were...

It is well known that specific antibody, under appropriate conditions, will prevent viral infections, but thorough knowledge concerning how this is accomplished is incomplete. Andrewes (1929) after working with virus III in tissue cultures suggested the possibility that immune serum acts by preventing the virus from entering the cells; if the serum fails to do this, invasion of cells occurs. Sa...

BACKGROUND Automated electrophoresis combined with enzymatic cholesterol staining might improve routine assessment of LDL- and HDL-cholesterol (LDLC and HDLC), as an alternative to the Friedewald equation and precipitation. A new method (Hydrasys; SEBIA) that adapts the cholesterol esterase/cholesterol oxidase reaction within urea-free gels was evaluated. METHODS Fresh sera from 725 subjects ...

INTRODUCTION A deficiency of 25-hydroxyvitamin D (25(OH)D) (the standard biomarker for vitamin D status) can have multiple impacts on the cardiovascular system. The aim of the study was to assess of the influence of 25(OH)D on severity of coronary atherosclerosis and lipid profile. MATERIAL AND METHODS The study involved prospectively 637 patients subject to coronary catheterization. The stag...

INTRODUCTION AND OBJECTIVE This study aimed at investigating the relationship between the lipid index (WS) in the examined cadets and duration of exposure to +Gz in the human centrifuge. MATERIALS AND METHODS The study involved 19 first-year cadets of the Polish Air Force Academy in Dęblin. Tests in the human centrifuge were repeated twice, i.e. prior to (test I) and 45 days after (test II). ...

Objective: Noise creates alteration in human health in both physical as well as psychological variations. Effect of noise on components of metabolic syndrome (MetS) has been discussed but not well established. The aim of this study was to investigate the MetS in female workers from textile mill. Methods: A total of 65 female workers were recruited for the study from the high noise (>70 dB) area...

OBJECTIVE To evaluate the hypolipemic and antioxidant effects of soy and green tea alone and/or in association in dyslipidemic subjects. METHODS One hundred dyslipidemic individuals were allocated into four groups. The soy group ingested 50 g of soy (kinako) daily, and the green tea group ingested 3 g of green tea in 500 mL of water per day. A third group ingested 50 g of soy and 3 g of green...

In previous experiments by Berenblum and Shubik (4), tumors were induced in mice by a single application of a carcinogenic hydrocar bon, followed by repeated applications of noncarcinogenic croton oil. Friedewald and Rous (7) similarly showed that tumors may be induced in the rabbit by a suboptimal dose of carcinogen fol lowed by wound healing and applications of non specific agents, such as tu...
