#1
Hadar Moran-Lev, Dror Mandel, Yosef Weisman, Amit Ovental, Ronit Lubetzky
BACKGROUND: Israel is a country with a sunny climate; however, vitamin D deficiency and insufficiency are common findings in certain populations whose exposure to sunlight is limited. Medical residency is known for long indoor working hours, thus theoretically limiting the opportunities for sun exposure. OBJECTIVES: To evaluate whether the vitamin D status among residents in a single medical center in Tel Aviv is below the normal range. METHODS: Forty-six residents (28 females, 18 males, average age 33...

Determinants of persistent low-level viraemia [PLLV, a viral load (VL) of between 50 and 500 copies/mL] have not been elucidated. In a case-control study, we evaluated the influence of micronutrients on PLLV in a population of 454 HIV-1 adults having initiated antiretroviral therapy (ART) between January 2007 and December 2011. Plasma levels of retinol (vitamin A), 25-OH vitamin D2 + D3, vitamin E and zinc were measured at ART initiation in cases (PLLV after 6 months of ART) and in controls (VL <50 copies/mL after 6 months)...

BACKGROUND: Vitamin D supplementation is widely recommended for infants, but the optimal dose remains unclear. High intake may result in hypercalcemia. METHODS: We evaluated the incidence of hypercalcemia during the first year of life in a cohort of 987 healthy children who received 10 or 30 μg of vitamin D3 supplementation daily. Ionized calcium (Ca-ion) was analyzed at 6 and 12 months, and serum 25-hydroxyvitamin D (25-OHD) and parathyroid hormone (PTH) concentration at 12 months...

Apolipoprotein E (APOE) is a member of the vertebrate protein family of exchangeable apolipoproteins that is characterized by amphipathic α-helices encoded by multiple nucleotide tandem repeats. Its equivalent in flying insects - apolipophorin-III - shares structural and functional commonalities with APOE, suggesting the possibility of an evolutionary relationship between the proteins. In contrast to all other known species, human APOE is functionally polymorphic and possesses three major allelic variants (ε4, ε3 and ε2)...

OBJECTIVES: Although the biological rationale for the association between folate, vitamin B12, and homocysteine with cognitive function seems plausible, conflicting results have been reported. This study aimed to determine the associations between 1-carbon (1-C) metabolism biomarkers (folate, vitamin B12, and homocysteine), and cognitive impairment at baseline and the rate of cognitive decline over 5 years in the very old. DESIGN: The Newcastle 85+ Study was a prospective longitudinal study of people 85 years old and followed over 5 years in Northeast England...

Phytoestrogens stimulate expression of the uterine estrogen receptor and regulate uterine functions in reproductive tissues. However, comprehensive understanding of the beneficial impacts of phytoestrogens on uterine biology at the molecular level remains unexplored. Interleukin-1β (IL-1β) expression is increased in the inflamed decidua and is associated with first trimester pregnancy loss. AglyMax-Sup has the same composition as that of the phytoestrogen supplement AglyMax but with added vitamins and other components...

BACKGROUND: Non-vitamin K antagonist oral anticoagulant (NOAC) use has significantly reduced intracerebral hemorrhagic (ICH) risk compared with standard anticoagulant treatment. Hematoma expansion (HE) is a known predictor of mortality in warfarin-associated ICH. Little is known about HE in patients using NOACs. METHODS: We conducted a retrospective chart review of patients with ICH admitted to Cedars-Sinai Medical Center from October 2010 to June 2016. We identified patients with concomitant administration of an oral anticoagulant and collected data including evidence of HE on imaging and modified Rankin Scale (mRS) at discharge...

Ischemia/reperfusion (I/R) induces prolongation of QT interval and action potential duration (APD), which is a major cardiac electrical disorder in patients with arrhythmias. However, the mechanism of QT interval prolongation induced by I/R remains unclear. In the present study, we hypothesized that the rapid component of delayed rectifier potassium (IKr) channel plays an important role in I/R-induced QT interval prolongation. We observed a marked attenuation of IKr and a significant prolongation of action potential duration (APD) in a simulated I/R system with sodium dithionite (Na2S2O4) in ventricular myocytes of guinea pigs...

Background • Vitamin K1 and K2 are not typically common in a Western diet because they are found in a variety of fermented foods. Vitamin K2 in particular has been demonstrated to restore mitochondrial function and has a key role in production of mitochondrial adenosine triphosphate. Thus, it is reasonable to speculate that dietary supplementation with vitamin K2 could increase the function of muscle with high mitochondrial content (ie, skeletal and cardiac muscle). Objective • The purpose of this study was to determine if 8 wk of dietary supplementation with Vitamin K2 could alter cardiovascular responses to a graded cycle ergometer test...

BACKGROUND: It is thought that airway inflammation is more common in obese asthmatic patients because inflammation is harder to control and does not respond well to glucocorticoid treatment. OBJECTIVE: This study's aim was to investigate the effect of obesity on airway and systemic inflammation in children with asthma and to identify the biomarkers that play a role in this inflammation. METHODS: The study included patients aged 6-16 years who were diagnosed with asthma in the paediatric allergy outpatient clinic of Bagcilar Training and Research Hospital in Turkey...

Vitamin E (α-tocopherol; VitE) is a lipophilic antioxidant required for normal embryonic development in vertebrates, but the long-term effects of embryonic VitE deficiency, and whether they are ameliorated by feeding VitE-adequate diets, remain unknown. We addressed these questions using a zebrafish (Danio rerio) model of developmental VitE deficiency followed by dietary remediation. Adult zebrafish maintained on VitE-deficient (E-) or sufficient (E+) diets were spawned to obtained E- and E+ embryos, respectively, which we evaluated up to 12 days post-fertilization (dpf)...
