The objective of the study was to compare the effects of essential vs long-chain omega (n)-3 polyunsaturated fatty acids (PUFAs) in polycystic ovary syndrome. In this 6-week, prospective, double-blinded, placebo (soybean oil)-controlled study, 51 completers received 3.5 g n-3 PUFA per day (essential PUFA from flaxseed oil or long-chain PUFA from fish oil).(More)
BACKGROUND Ventilator-associated pneumonia is the leading nosocomial infection in critically ill patients. The frequency of ventilator-associated pneumonia caused by multidrug-resistant bacteria has increased in recent years, and these pathogens cause most of the deaths attributable to pneumonia. The authors, therefore, evaluated factors associated with(More)
α-Cyclodextrin (α-CD) is a soluble fiber derived from corn. It has previously been reported that early intervention with Mirafit fbcx, a trademarked name for α-CD, has beneficial effects on weight management in obese individuals with type 2 diabetes, and that it preferentially reduces blood levels of saturated and trans fats in the LDL receptor knockout(More)
BACKGROUND It has been suggested that perturbations in branched-chain amino acid (BCAA) catabolism are associated with insulin resistance and contribute to elevated systemic BCAAs. Evidence in rodents suggests dietary protein rich in BCAAs can increase BCAA catabolism, but there is limited evidence in humans. OBJECTIVE We hypothesize that a diet rich in(More)
This study was carried out on 18 albino rats. The control group, consisting of six rats, was fed a normal diet and tap water. The other rats were given a zinc-deficient diet and deionized water. Two weeks later the latter group was again divided into two into smaller groups. The first of these groups was given an given an additional 100 ppm of zinc acetate.(More)
Wingless-type MMTV integration site family member (WNT) signaling and WNT-inhibitors have been implicated in regulation of adipogenesis, insulin resistance, pancreatic function, and inflammation. Our goal was to determine serum proteins involved in WNT signaling (WNT5 and WISP2) and WNT inhibition (SFRP4 and SFRP5) as they relate to obesity, serum(More)
BACKGROUND/OBJECTIVES Polycystic ovary syndrome (PCOS) is commonly associated with insulin resistance, dyslipidemia and increased inflammation, which all benefit from dietary intake of monounsaturated and n-3 polyunsaturated fatty acids (MUFA and n-3 PUFA). Our goal was to compare the effects of MUFA-rich almonds vs n-3/n-6 PUFA-rich walnuts on metabolic(More)
BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder that is associated with increased inflammation, insulin resistance, and elevated risk of metabolic complications. hs-CRP is the most reliable marker of inflammation in PCOS patients. When hs-CRP is elevated, it can indicate increased risk of cardiovascular disease. The purpose of the(More)
OBJECTIVE To determine insulin resistance and response in patients with polycystic ovary syndrome (PCOS) and normal glucose tolerance (NGT), impaired fasting glucose (IFG), impaired glucose tolerance, and combined glucose intolerance (CGI). RESEARCH DESIGN AND METHODS In this cross-sectional study, 143 patients with PCOS (diagnosed on the basis of(More)
