BACKGROUND: Dietary sugar and starch affect plasma glucose and insulin concentrations. Little information is available about the effect of dietary fibre on plasma glucose and insulin concentration. It is hypothesized that different dietary fibre compositions will alter post-prandial glycaemic- and insulinemic index of test meals. The objective was to measure postprandial glucose and insulin concentrations in horses fed meals of different fibre compositions. METHODS: Blood was drawn via jugular vein puncture and the glycaemic and insulinemic index were calculated...

BACKGROUND: Type 1 diabetes mellitus (T1D) is mediated by autoaggressive T effector cells with an underlying regulatory T cell (Treg) defect. Vitamin D (VD) deficiency is highly prevalent in T1D which can aggravate immune dysfunction. High dose VD treatment may enhance Tregs and improve metabolism in T1D patients. METHODS: In a randomized, double-blind, placebo-controlled trial with cross-over design, patients received either for three months cholecalciferol 4000 IU/d, followed by three months placebo or the sequential alternative...

Beauveria bassiana is an entomopathogenic fungus that grows both in vivo and in vitro. In vivo it can colonize live insect hosts, and tissue digestion occurs by secreted hydrolytic exoenzymes. It can also colonize dead insect tissue provided this is free from competing microorganisms. Depending on whether the host is alive or dead the expression (quality/quantity) of the exoenzymes may vary. We have grown several isolates of B. bassiana in shaking flasks for 120 h at 25 °C in order to evaluate the maximal exoenzyme production using two diet regimes...

Adverse reactions of injectable drugs usually occur at first administration and are closely associated with the dosage and speed of injection. This phenomenon is correlated with the anaphylactoid reaction. However, up to now, study methods based on antigen detection have still not gained wide acceptance and single physiological indicators cannot be utilized to differentiate anaphylactoid reactions from allergic reactions and inflammatory reactions. In this study, a reliable method for the evaluation of anaphylactoid reactions caused by injectable drugs was established by using multiple physiological indicators...

OBJECTIVE: In most cases, the 5 first line drugs are recommended for management of hypertension without preference for one or the other. However, it is unclear whether different classes of anti-hypertensive agents have different effect on survival in low risk, uncomplicated hypertension. The aim of this study was to evaluate effects of 4 classes of first line anti-hypertensive agents on improving survival in patients with low risk, uncomplicated hypertension. DESIGN AND METHOD: Adult hypertensive patients without chronic kidney disease, end stage renal disease, diabetes mellitus, acute coronary syndrome, and heart failure in 2002 were selected from Korean National Health Insurance sample cohort consisting of one million subjects...

Beginning with the Veterans Administration (VA) Cooperative Hypertension Study of the 1960 s, blood pressure (BP) lowering with antihypertensive medications has been shown to reduce major cardiovascular (CV) outcomes, including coronary heart disease, stroke, heart failure (HF) and CV and all-cause mortality in randomized controlled CV outcome trials. Multiple drugs were usually required in these trials to lower BP in treated participants. Medication regimens in the early trials, including the VA trial, included a thiazide-type diuretic (TTD) as initial therapy...

Aldosterone's deleterious pathophysiological effects on the cardiovascular system if blocked by mineralcorticord antagonists (MRAs) logically should lead to improvement in heart function and outcomes in heart failure (HF). The first trial to test this hypothesis was tthe RALES trial in 1999 which treated patients with class III-IV HF with spironolactone. It showed significant reduction in mortality and cardiovascular hospitalzation rates. This was confirmed & extended in EMHASIS-HF RCT with classs II-III being treated with ACEIs & BB who received placebo or elperinone (a MRA) with again a statistically significant fall in mortality & hospitalization...

Vascular smooth muscle cell (VSMC) proliferation is a key event in the development of in‑stent restenosis. Evodiamine is an indole alkaloid extracted from the Chinese medicine, evodia, and has been shown to inhibit tumor cell proliferation and protect the cardiovascular system. However, whether evodiamine affects VSMC proliferation remains to be elucidated. Therefore, the present study examined the effects and the mechanisms of action of evodiamine on the proliferation of rat VSMCs. The cells were treated with evodiamine alone or in combination with platelet‑derived growth factor‑BB (PDGF‑BB) stimulation...

BACKGROUND: The development of platelet-rich fibrin (PRF) drastically simplified the preparation procedure of platelet-concentrated biomaterials, such as platelet-rich plasma (PRP), and facilitated their clinical application. PRF's clinical effectiveness has often been demonstrated in pre-clinical and clinical studies; however, it is still controversial whether growth factors are significantly concentrated in PRF preparations to facilitate wound healing and tissue regeneration. To address this matter, we performed a comparative study of growth factor contents in PRP and its derivatives, such as advanced PRF (A-PRF) and concentrated growth factors (CGF)...

BACKGROUND: Platelet-rich fibrin (PRF), a platelet-rich plasma (PRP) derivative mainly composed of fibrin networks, has been increasingly demonstrated to be effective in wound healing in clinical and pre-clinical animal studies. However, there has still been a concern that major growth factors may significantly be loss from PRF during its preparation through the slow clotting process. To address this concern, we compared the angiogenic potential of PRF and PRP by standardization of procedures based on volume ratios...

The percolation problem of irreversibly deposited heteronuclear dimers on square lattices is studied. A dimer is composed of two segments, and it occupies two adjacent adsorption sites. Each segment can be either a conductive segment (segment type A) or a nonconductive segment (segment type B). Three types of dimers are considered: AA, BB, and AB. The connectivity analysis is carried out by accounting only for the conductive segments (segments type A). The model offers a simplified representation of the problem of percolation of defective (nonideal) particles, where the presence of defects in the system is simulated by introducing a mixture of conductive and nonconductive segments...

For the first time, porous organic polymers (POPs) based on the smallest buckybowl, corannulene (BB-POPs) have been synthesized. Three POPs were synthesised via Sonogashira co-polymerization of 1,2,5,6-tetrabromocorannulene and alkyne linkers. BB-POP-3 exhibits the highest surface area (SABET = 560 m(2) g(-1)) and CO2 adsorption of 11.7 wt%, while they retain the redox properties of corannulene.

A preclinical study demonstrated anti-proliferative and apoptotic effect of propranolol on multiple myeloma (MM) cell. Clinical studies suggested that beta blocker (BB) might impact the prognosis of breast, prostate, colorectal, ovarian, lung, and skin cancer. This retrospective study evaluated the effect of BB in MM disease-specific survival (DSS) and overall survival (OS). Among 1971 newly diagnosed MM patients seen at Mayo Clinic between 1995 and 2010, usage of BB and other cardiac (or antihypertensive) medications were abstracted...
