BackgroundNon-sputum-based triage tests for tuberculosis are a priority ending tuberculosis. We aimed to evaluate the diagnostic accuracy of late-prototype Xpert MTB Host Response (Xpert HR) blood-based assay.MethodsWe conducted prospective study among outpatients with presumed in outpatient clinics Viet Nam, India, Philippines, Uganda, and South Africa. Eligible participants were aged 18 years or older reported cough lasting at least 2 weeks. excluded those receiving treatment preceding 12...

Elevated LDL-C, lipoprotein(a) [Lp(a)], and inflammation are associated with greater risk for atherosclerotic cardiovascular events. Consumption of individual nut types decreases these factors but knowledge about the effect mixed nuts on Lp(a) is limited. The objective this study was to determine effects consuming 42.5 g/day Lp(a), inflammatory markers in individuals overweight or obesity.In a 16-week randomized control trial, 29 participants obesity (BMI 25-40 kg/m2) consumed either...

Diagnosing childhood pulmonary tuberculosis (TB) is a challenge. This led the Uganda National Tuberculosis and Leprosy Program (NTLP) to develop clinical treatment decision algorithm (TDA) for children. However, there limited data on its accuracy, how it compares new World Health Organization (WHO) TB TDAs study aimed evaluate compare accuracy of 2017 NTLP diagnostic with 2022 WHO among We analyzed four years from children <15 old in Kampala, Uganda.

Preterm rabbits from 14 litters were delivered at 27 d gestation, anesthetized, and treated with surfactant birth, 15 min, or 30 min after the onset of mechanical ventilation. Doses ranging 0 to 100 mg/kg body weight given intratracheally ventilated for 45 birth. Pressure-volume curves dynamic compliances demonstrated that dose response progressively decreased delayed treatment. Following treatments 50 peak lung volumes 35 cm H2O increased by 49, 30, 8.4%, respectively over those untreated...

Studies were conducted to quantify ovine fetal and adult atrial natriuretic factor (ANF) metabolism. A total of 14 pregnant ewes with singleton fetuses prepared vascular catheters. In protocol 1, six (mean gestation, 131 +/- 1 days) received intravenous infusions synthetic human ANF (hANF, 100 ng.min-1.kg-1) for 60 min. Mean basal plasma levels increased from 180 44 pg/ml a steady-state level 1,233 192 pg/ml. 2, five 130 successive 40-min hANF at 5, 25, ng.min-1.kg-1. Although (522 135...

Pregnant women may be exposed to exercise, thermal, or gastrointestinal (hyperemesis) water loss, all of which commonly induce a greater than 10 mosmol increase in plasma osmolality. Although fetal osmolality is dependent on maternal osmolality, the impact dehydration and subsequent rehydration fetus has not been explored. Five pregnant ewes with singleton fetuses (136 +/- 1 day) were deprived for 36 h resulting significant (298 3.4 313 5.0 mosmol). In response dehydration, (297.0 4.1 309.3...

Abstract A major mechanism for Na + transport across epithelia occurs through epithelial channels (ENaC). ENaC is a multimeric channel consisting of three subunits (α, β, and γ). The α‐subunit critical function. In specific culture conditions, the rat submandibular gland cell line (SMG‐C6) demonstrates minimal properties exposure to dibutyryl cAMP (DbcAMP) up 48 h caused an elevation α‐ENaC mRNA protein expression amiloride‐sensitive short‐circuit current (I SC ). Here we examined early...

Abstract α‐ENaC expression and activity is regulated by a variety of hormones including β‐adrenergic agonists via the second messenger cAMP. We evaluated early intermediate pathways involved in up‐regulation SGK1 DbcAMP whether prerequisite for induction expression.

Heart disease, caused by atherosclerosis, is the leading cause of death. Maintaining vascular integrity crucial to reducing atherosclerosis risk. Mangos are rich in fiber, vitamins, minerals, and phytochemicals that may offer cardioprotective immune-boosting benefits. However, their effects on vasculature immune system adults with overweight obesity remain unclear. The objective this study was investigate mango consumption health function obesity.
