An intact blood-brain barrier (BBB) limits entry of pro-inflammatory and neurotoxic blood-derived factors into the brain parenchyma. The BBB is damaged in Alzheimer's disease (AD), which contributes significantly to the progression of AD pathologies and cognitive decline. However, the mechanisms underlying BBB breakdown in AD remain elusive and no interventions are available for treatment or prevention. We and others recently established that inhibition of the mammalian/mechanistic target of rapamycin (mTOR) pathway with rapamycin yields significant neuroprotective effects, improving cerebrovascular and cognitive function in mouse models of AD...

The prevalence of diabetes mellitus (DM) and impaired glucose tolerance (IGT) has increased worldwide, although their prevalence and determinants among Tibetans are currently unknown. We thus aimed to explore the prevalence of and risk factors for DM and IGT among Tibetans in China. In 2011, 1659 Tibetan adults (aged ≥ 18 years) from Changdu, China, were recruited to this cross-sectional study. They completed a questionnaire and underwent physical examinations and laboratory testing to assess risk factors for DM and IGT...

OBJECTIVE: Loss-of-function mutations in APOC3 associate with low remnant cholesterol levels and low risk of ischemic vascular disease (IVD). Because some studies show an additional association with low levels of low-density lipoprotein cholesterol (LDL-C), low LDL-C may explain the low risk of IVD in APOC3 loss-of-function heterozygotes. We tested to what extent the low risk of IVD in APOC3 loss-of-function heterozygotes is mediated by low plasma remnant cholesterol and LDL-C. APPROACH AND RESULTS: In APOC3 loss-of-function heterozygotes versus noncarriers, we first determined remnant cholesterol and LDL-C levels in meta-analyses of 137 895 individuals...

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 (PCSK9), which plays a crucial role in lipoprotein metabolism, has been also regarded as an important marker for atherosclerosis. Available evidence indicated that 2-h postchallenge plasma glucose (2-hPG) could be another biomarker for atherosclerosis. However, currently the association between circulating PCSK9 and 2-hPG remains unclear. Here, we explored this potential link in a Chinese Han population. METHODS: Totally, 600 Chinese Han subjects from Nanjing district, China, were enrolled for the 75-g oral glucose tolerance test (OGTT), and they included normal glucose tolerance (NGT, n = 200), impaired glucose regulation (IGR, n = 200), and type 2 diabetes (T2DM, n = 200)...

The purpose of the study was to evaluate the relationship between arginine-levodopa-induced growth hormone (GH) secretion and nonalcoholic fatty liver disease (NAFLD) in obese children. This study includes a total of 84 obese and 43 normal weight children. The obese subjects are divided into two groups based on the presence or absence of NAFLD. Clinical examination, anthropometric and laboratory examinations, and liver ultrasonography are assessed for all participants. The obese group had significantly lower peak stimulated GH (p<0...

Background: Minimal change disease (MCD) is a kind of nephrotic syndrome (NS). In this study, we aimed to establish a mathematical diagnostic model based on biological parameters to classify MCD. Methods: A total of 798 NS patients were divided into MCD group and control group. The comparison of biological indicators between two groups were performed with t-tests. Logistic regression was used to establish the diagnostic model, and the diagnostic value of the model was estimated using receiver operating characteristic (ROC) analysis...

OBJECTIVE: Individuals with bipolar disorder (BD) frequently suffer from cardiovascular disease (CVD), and it is a leading cause of mortality. Clinicians use routine laboratory tests, including a lipid profile, to predict cardiovascular risk. In addition, a particular lipid ratio, the atherogenic index of plasma (AIP), is a sensitive, new parameter that can be used to assess highrisk groups. To our knowledge, this is the first study evaluating cardiovascular risk via AIP in different stages of BD...

INTRODUCTION: The Kham Tibetans are one of several Tibetan ethnic subgroups living in the Kham area of China. Because studies on the high-altitude adaptation of the Kham people are scant, the main aim of this study is to investigate whether the response to hypoxia, especially polycythemia status, in the Kham Tibetans is different from other Tibetan ethnic subgroups. METHODS: The primary investigation was conducted on 346 native Kham Tibetan adults (268 men and 78 women) from 3 herdsmen villages located in Hongyuan County situated at an altitude of greater than 3600 m...

BACKGROUND: The genome-wide association study has founded hypertension-related single nucleotide polymorphism (SNP) rs11191548 near CYP17A1 encoding a key enzyme involved in steroid metabolism, but the molecular mechanisms are not understood and the associations of the SNP with hypertension-related traits are not fully described, especially in children. The aim of the present study is to investigate the associations between the SNP and two hypertension-related traits, lipids and leptin...

BACKGROUND: Metabolic Syndrome (MetS) is an energy-disturbance disease associated with insulin resistance. Hence, the intake of energy-rich macronutrients might affect some MetS components. The aim of this study was to explore the association of ingested macronutrients with MetS components in older women. METHODS: A cross sectional study was conducted in 245 older women (≥60 years). Whole-body dual-energy X-ray absorptiometry was used to assess total body fat, percentage body fat (absolute and relative), and skeletal muscle mass...

The aim of this study was to evaluate the effect of Irvingia gabonensis on metabolic syndrome (MetS), insulin sensitivity, and insulin secretion. A randomized, double-blind, placebo-controlled clinical trial was performed in 24 patients with MetS in accordance with the International Diabetes Federation criteria. Twelve patients received I. gabonensis (150 mg) twice a day during 90 days, and 12 patients received placebo.

BACKGROUND: Familial hypercholesterolemia (FH) is a genetic disorder that result in abnormally high low-density lipoprotein cholesterol levels, markedly increased risk of coronary heart disease (CHD) and tendon xanthomas (TX). However, the clinical expression is highly variable. TX are present in other metabolic diseases that associate increased sterol concentration. If non-cholesterol sterols are involved in the development of TX in FH has not been analyzed. METHODS: Clinical and biochemical characteristics, non-cholesterol sterols concentrations and Aquilles tendon thickness were determined in subjects with genetic FH with (n = 63) and without (n = 40) TX...

BACKGROUND: Myasthenia gravis (MG) is an autoimmune disorder of the neuromuscular junction in which a clinical diagnosis may be confirmed with serological testing. The most common autoantibodies used to support a diagnosis of MG are anti-acetylcholine receptor antibodies and anti-muscle-specific tyrosine kinase antibodies. In cases in which both of these autoantibodies are negative (termed double-seronegative [dSNMG]), other autoantibodies such as low-density lipoprotein receptor-related protein 4 (LRP4) may be used to aid in diagnosis...

Breast cancer is amongst the most common cancers causing death of women worldwide. Breast cancer occurrence is more prominent in people with diabetes. A recent trend is management of diabetes and cancer has evolved to be natural remedy including single molecule therapy or combination. In this study, we investigated the effect of inotodiol on breast cancer growth in diabetic conditions. Inotodiol is a lanostane triterpenoid found in natural resources like edible mushroom Inonotus obliquus. We established a rat model of diabetic-breast cancer by treating female Sprague-Dawley rats with streptazotocin (STZ) at 35 mg/kg followed by induction of breast cancer by administration of 7,12-dimethylbenz(a)anthracene (DMBA) at 10 mg/kg...

BACKGROUND: Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9is) are an innovative treatment option for patients with familial hypercholesterolemia or clinical atherosclerotic cardiovascular disease who require further lowering of low-density lipoprotein cholesterol. However, the high costs of these agents have spurred payers to implement utilization management policies to ensure appropriate use. We examined prior authorization (PA) requirements for PCSK9is across private and public US payers...
