Soluplus® is a graft amphiphilic copolymer that is frequently used as an excipient in solid dosage forms as a dissolution and a solubility enhancer. We discovered that Soluplus® can be dissolved in vitamin E. The result is a tacky and highly adhesive material. Our research objective was to evaluate the rheological, adhesive, and textural properties of the Soluplus® /Vitamin E composites. In this study, Soluplus® was dissolved under heat in vitamin E at increasing concentrations from 0 to 40% (by weight)...

Serum 25-hydroxyvitamin D /25OHD/ levels in humans are determined primarily by environmental factors such as UV-B radiation and diet, including vitamin D intake. Although some genetic determinants of 25OHD levels have been shown, the magnitude of this association has not yet been clarified. The present study evaluates the genetic contribution to total- /t-25OHD/ and free-25OHD /f-25OHD/ in a representative sample of the Hungarian population (n = 462). The study was performed at the end of winter to minimize the effect of sunlight, which is a major determinant of serum vitamin D levels...

So far, liver fibrosis still has no clinically-approved treatment. The loss of stored vitamin-A (VA ) in hepatic stellate cells (HSCs), the main regulators to hepatic fibrosis, can be applied as a mechanism for their targeting. Valsartan is a good candidate for this approach; it is a marketed oral-therapy with inverse- and partial-agonistic activity to the over-expressed angiotensin-II type1 receptor (AT1R) and depleted nuclear peroxisome proliferator-activated receptor-gamma (PPAR-γ), respectively, in activated HSCs...

The antiviral and immunomodulatory role of vitamin D has been shown in various viral infections. However, there is scanty literature available about the effect of vitamin D supplementation in herpes simplex virus-1 (HSV-1) infection. Therefore, the present study aimed to evaluate the role of two different forms of vitamin D: 25-hydroxyvitamin D3 (25D3) and 1,25-dihydroxyvitamin D3 (1,25D3) against HSV-1 in HeLa cells. The HeLa cells were supplemented with either 25D3 or 1,25D3 before HSV-1 infection and were studied after 6, 12, and 24 h postinfection (p...

OBJECTIVES: Vitamin D is an important component of bone metabolism. Skin cells synthesize vitamin D when exposed to the sun. However, prolonged sun exposure damages the skin and increases the risk for skin cancer. The objective is to evaluate and compare the attitudes and recommendations of family doctors, dermatologists, and endocrinologists on exposure to the sun and vitamin D. METHODS: In a cross-sectional study, a questionnaire was completed by personal interview in a study population of 78 family doctors, 21 dermatologists, and 22 endocrinologists...

In Zambia, chronic malnutrition still is one of the most common problem among children. To fight against malnutrition, the easiest short-term solution could be to combine specific types of food with affordable local plants. A large variety of natural food resources grow in Zambia, such as Moringa oleifera (MO), whose leaves are known for their health benefits, but are not consumed much by local populations. We analysed Zambian MO powder obtained from dried leaves and found that it contains large amounts of protein, minerals and vitamins, such as iron, calcium and carotenoids...

Sulfur, most abundantly found in the environment as sulfate (SO4 2- ), is an essential element in metabolites required by all living cells, including amino acids, co-factors and vitamins. However, current understanding of the cellular delivery of SO4 2- at the molecular level is limited. CysZ has been described as a SO4 2- permease, but its sequence family is without known structural precedent. Based on crystallographic structure information, SO4 2- binding and flux experiments, we provide insight into the molecular mechanism of CysZ-mediated translocation of SO4 2- across membranes...

BACKGROUND: Adequate levels of vitamin D are required to ensure bone health and minimize the incidence of multiple extraskeletal diseases. Although total 25-hydroxyvitamin D (25OHD) remains the recommended biomarker for assessing vitamin D status, it has been speculated that free 25OHD correlates better with clinical outcomes. The calculation of free 25OHD depends on the levels of vitamin D binding protein (DBP), the determination of which involves different immunoassays and has led to varying results and conclusions...

BACKGROUND: Fibrinogen prothrombin time derived method (FIBPT-d) with photo-optical coagulometers is easy and economical. However, there are few reports on the behavior of this test on samples from patients anticoagulated with direct oral anticoagulants (DOACs) or low molecular weight heparin (LMWH). OBJECTIVE: To compare fibrinogen results obtained by Clauss method (FIB C) and FIBPT-d with two thromboplastins in anticoagulated patients. POPULATION: 295 consecutive anticoagulated patients: 99 vitamin K antagonist (VKA), 49 unfractionated heparin (UFH), 47 LMWH, 50 rivaroxaban and 50 dabigatran; and 100 healthy controls (NC)...

Atrial fibrillation (AF) is associated with various cardiovascular comorbidities, such as hypertension, heart failure and diabetes mellitus, which increases not only the risk of ischaemic stroke but also of myocardial infarction and mortality. Oral anticoagulation for stroke prevention is the cornerstone of management for people with AF, both with vitamin K antagonists, or with non-vitamin K antagonist oral anticoagulants (NOACs), which show efficacy, safety and convenience compared with vitamin K antagonists [1]...

AIM: Vitamin D (VD) influences genetic expression through its receptor (VDR). VD pathway gene polymorphisms seem to influence antiviral drug pharmacokinetics and therapeutic outcome/toxicity. We investigated the association between daclatasvir (DCV) plasma concentrations and genetic variants (SNPs) associated with the VD pathway. PATIENTS & METHODS: Chronic hepatitis C patients treated with DCV from 2014 to 2016 were included. Genotypes were assessed through real-time PCR and plasma concentrations through liquid chromatography...

The non-vitamin K antagonist oral anticoagulants (NOACs), which include dabigatran, apixaban, edoxaban and rivaroxaban, are preferred over vitamin K antagonists for stoke prevention in most patients with non-valvular atrial fibrillation. The NOACs are contraindicated in atrial fibrillation patients with rheumatic mitral stenosis or mechanical heart valves. There is evidence that bioprosthetic heart valves are less thrombogenic than mechanical heart valves, but it is unknown whether the risk of thromboembolism in atrial fibrillation patients with bioprosthetic valves differs from that in patients without such valves...

BACKGROUND: For many years, the Roux-en-Y Gastric Bypass (RYGB) was considered a good balance of complications and weight loss. According to several short-term studies, single anastomosis duodenal switch or stomach intestinal pylorus sparing surgery (SIPS) offers similar weight loss to RYGB with fewer complications and better diabetes resolution. No one has substantiated mid-term complication and nutritional differences between these two procedures. This paper seeks to compare complication and nutritional outcomes between RYGB and SIPS...
