The anti-hyperlipidemic effects of crude crabapple extracts derived from Malus 'Red jade', Malus hupehensis (Pamp.) Rehd. and Malus prunifolia (Willd.) Borkh. were evaluated on high-fat diet induced obese (HF DIO) mice. The results revealed that some of these extracts could lower serum cholesterol levels in HF DIO mice. The same extracts were also parallelly analyzed by LC-MS in both positive and negative ionization modes. Based on the pharmacological results, 22 LC-MS variables were identified to be correlated with the anti-hyperlipidemic effects using partial least square discriminant analysis (PLS-DA) and independent samples t-test...

Exercise training reduces renin-angiotensin system (RAS) activation, decreases plasma and tissue oxidative stress and inflammation in hypertension. However, the temporal nature of these phenomena in response to exercise is unknown. We sought to determine in spontaneously hypertensive rats (SHR) and age-matched WKY controls the weekly effects of training on blood pressure (BP), plasma and left ventricle (LV) Ang II and Ang-(1-7) content (HPLC), LV oxidative stress (DHE staining), gene and protein expression (qPCR and WB) of pro-inflammatory cytokines, antioxidant enzymes and their consequence on hypertension-induced cardiac remodeling...

INTRODUCTION: microRNAs (miRNAs) destabilize mRNA transcripts and inhibit protein translation. miR-145 is of particular interest in cystic fibrosis (CF) as it has a direct binding site in the 3'-untranslated region of CFTR and is upregulated by the CF genetic modifier TGF-β. HYPOTHESIS: miR-145 mediates TGF-β inhibition of CFTR synthesis and function in airway epithelia. METHODS: Primary human CF (F508del homozygous) and non-CF airway epithelial cells (AECs) were grown to terminal differentiation at air-liquid interface on permeable supports...

Selective covalent inhibition of kinases by targeting poorly conserved cysteines has proven highly fruitful to date in the development of chemical probes and approved drugs. However, this approach is limited to ~200 kinases possessing such a cysteine near the ATP-binding pocket. Herein, we report a novel approach to achieve selective, irreversible kinase inhibition, by targeting the conserved catalytic lysine residue. We have illustrated our approach by developing selective, covalent PI3Kδ inhibitors that exhibit nanomolar potency in cellular assays, and a duration of action >48 h in CD4+ T cells...

The prevalence of obesity is increasing among children nationally. Native American children from Zuni Pueblo appear to be at increased risk for obesity, which also increases the risk for the metabolic syndrome, diabetes, and cardiovascular disease. While exercise and physical fitness can prevent or forestall these developments, predictors of physical fitness in this population are unknown. Forty-seven Native American adolescents completed four aspects of the Presidential Fitness Challenge (push-ups, sit-ups, step-ups, and timed walking) during screening for another study, and fitness was empirically summarized with a Presidential Fitness Index...

Cerebral autoregulation (CA) maintains cerebral blood flow (CBF) in the presence of systemic blood pressure changes. Brain injury can cause loss of CA and resulting dysregulation of CBF, and the degree of CA impairment is a functional indicator of cerebral tissue health. Here, we demonstrate a new approach to noninvasively estimate cerebral autoregulation in healthy adult volunteers. The approach employs pulsatile CBF measurements obtained using high-speed diffuse correlation spectroscopy (DCS). Rapid thigh-cuff deflation initiates a chain of responses that permits estimation of rates of dynamic autoregulation in the cerebral microvasculature...
