Effects of Nigella sativa on glycemic control, lipid profiles, and biomarkers of inflammatory and oxidative stress: A systematic review and meta-analysis of randomized controlled clinical trials.

The aim of this systematic review and meta-analysis was to evaluate the effects of Nigella sativa (N. sativa) on glycemic control, lipid profiles, and biomarkers of inflammatory and oxidative stress. Two independent authors systematically examined online databases consisting of, EMBASE, Scopus, PubMed, Cochrane Library, and Web of Science from inception until October 30, 2019.

Practical strategies for modulating foam cell formation and behavior.

Although high density lipoprotein (HDL)-mediated reverse cholesterol transport is crucial to the prevention and reversal of atheroma, a recent meta-analysis makes evident that current pharmaceutical strategies for modulating HDL cholesterol levels lower cardiovascular risk only to the extent that they concurrently decrease low density lipoprotein (LDL) cholesterol. This corresponds well with findings of a recent Mendelian randomization analysis, in which genetic polymorphisms associated with HDL cholesterol but no other known cardiovascular risk factors failed to predict risk for myocardial infarction. Although it is still seems appropriate to search for therapies that could improve the efficiency with which HDL particles induce reverse cholesterol transport, targeting HDL cholesterol levels per se with current measures appears to be futile.

Animal models of atherosclerosis.

In this mini-review several commonly used animal models of atherosclerosis have been discussed. Among them, emphasis has been made on mice, rabbits, pigs and non-human primates. Although these animal models have played a significant role in our understanding of induction of atherosclerotic lesions, we still lack a reliable animal model for regression of the disease.

Stress-relieving effects of short-term balneotherapy - a randomized controlled pilot study in healthy adults.

Background: Stress-relieving effects of balneotherapy compared to progressive muscle relaxation (PMR) and to resting were investigated by measuring subjective relaxation and salivary cortisol. It was also examined whether participants with a high versus low stress level would have a different relaxation response.

Methods: A sample of healthy volunteers was randomized to balneotherapy, PMR, or a resting control group, each intervention lasting for 25 min.

Hypothesis: smoking decreases breast feeding duration by suppressing prolactin secretion.

A number of studies, including new data summarized here, conclude that breast feeding duration is lower in smoking mothers. Although some have suggested that this merely reflects poor health motivation in those prone to smoke, several lines of evidence support the view that chronic smoking does indeed compromise breast feeding by suppressing prolactin secretion and thereby lowering breast milk volume. Moreover, a recent clinical trial shows that an effective smoking cessation program can boost breast feeding duration in smokers.

Hydrangenone, a new isoprenoid with an unprecedented skeleton from Salvia hydrangea.

Hydrangenone, a new heptacyclic isoprenoid with a 6/7/6/5/5 membered carbon ring skeleton, was isolated from the aerial parts of Salvia hydrangea. The structure was established by extensive NMR spectroscopic methods. The relative and absolute configuration of 1 was assigned by NOESY and X-ray crystallographic analysis and by comparison of experimental and calculated electronic circular dichroism (ECD) spectra.

Triterpenoids with rare carbon skeletons from Salvia hydrangea: antiprotozoal activity and absolute configurations.

Salvadione C (1) and perovskone B (2), two new triterpenoids with rare carbon skeletons, were isolated from an antiplasmodial n-hexane extract of Salvia hydrangea. The absolute configuration was determined by comparison of experimental and calculated electronic circular dichroism (ECD) spectra. In vitro activity against Plasmodium falciparum K1 strain, Trypanosoma brucei rhodesiense STIB 900 strain, and cytotoxicity in rat myoblast (L6) cells were determined.

Polymorphisms of the hypoxia-inducible factor 1 gene and peripheral artery disease.

Hypoxia-inducible factor 1 (HIF1) is a key regulator of angiogenesis and is involved in inflammation, which are two important features of the pathogenesis of peripheral artery disease (PAD). The gene for the HIF1-alpha subunit (HIF1A) carries two common mis-sense mutations, P582S (C>T, rs11549465) and A588T (G>A, rs11549467), which both have been related to increased trans-activation capacity of HIF1-alpha. The aim of the present study was to analyze the role of these polymorphisms in PAD.

The fibrinogen gamma 10034C>T polymorphism is not associated with Peripheral Arterial Disease.

Conversion of fibrinogen to fibrin plays an essential role in hemostasis and results in stabilization of the fibrin clot. Fibrinogen consists of three pairs of non-identical polypeptide chains, encoded by different genes (fibrinogen alpha [FGA], fibrinogen beta [FGB] and fibrinogen gamma [FGG]). A functional single nucleotide polymorphism (SNP) in the 3' untranslated region of the FGG gene (FGG 10034C>T, rs2066865) has been associated with deep venous thrombosis and myocardial infarction.

omega-3 Fatty acids infusions as adjuvant therapy in rheumatoid arthritis.

Background: The present study investigated the efficacy and safety of parenteral omega-3 fatty acids (omega-3 FA) in patients with active rheumatoid arthritis (RA).

Methods: We performed a double-blind, randomized, placebo-controlled study in 23 patients with moderate to severe RA. Patients received either 0.

A "mini-fast with exercise" protocol for fat loss.

From the standpoint of promoting leanness, exercise is of most value if oxidation of stored fat is maximized during and following the exercise sessions. Bahadori has proposed that this can best be achieved if prolonged exercise of moderate intensity is performed during a 12-14 h "mini-fast" that entails skipping a meal; if subsequent food consumption features low-fat foods, the fat stores expended during and after the exercise will not be fully repleted by dietary fat. Thus, prolonged compliance with such a regimen should lead to steady loss of body fat until a much leaner equilibrium body composition is attained.

Paradoxical effects of fenofibrate and nicotinic acid in apo E-deficient mice.

Atherosclerosis is a complex vascular disease initiated by abnormal accumulation of plasma lipoproteins in the subendothelial space. Elevated levels of plasma triglycerides (TG) and low-density lipoprotein (LDL)-cholesterol as well as low concentrations of high-density lipoprotein (HDL) play a causal role in the development and progression of atherosclerotic lesions. We have shown that apolipoprotein E-deficient (apo E-KO) mice have elevated triglyceride levels plus diminished HDL concentrations.

The L10P polymorphism of the transforming growth factor-beta 1 gene is not associated with breast cancer risk.

Transforming growth factor-beta 1 (TGF-beta1) is a potent inhibitor of proliferation of epithelial, endothelial and hematopoietic cells and acts as a tumor suppressor. The gene for TGF-beta1, TGFB1, carries a common T/C variation of nucleotide 29, resulting in a leucine (L) to proline (P) polymorphism at codon 10 (TGFB1 L10P). The less common 10P allele has repeatedly been linked to higher TGF-beta1 levels and in at least one study to a lower incidence of breast cancer.
