BACKGROUND: Isoflavones are natural compounds belonging to the class of isoflavonoids, molecules with a chemical structure based on the 3-phenyl chromen-4-one backbone. As a particular element, the isoflavones are called also phytoestrogens, due to the structural similarity with 17-β estradiol, the primary female sex hormone, presenting both estrogen-agonist and estrogen-antagonist properties. This class of secondary plant metabolites has been extensively reported in the literature for a wide range of therapeutic activities including antioxidant, chemopreventive, anti-inflammatory, anti-allergic, antibacterial, cardio preventive effects...

Yuanyuan Cheng, Jianhui Rong
BACKGROUND: Myocardial infarction is characterized by the interruption of blood flow through the heart, directly causing mortality and disability worldwide. Cardiac macrophages exhibit distinct phenotypes (e.g., M1 or M2) and functions (e.g., proinflammatory or anti-inflammatory) in response to the alterations of myocardial microenvironment, and subsequently exacerbate or resolve the inflammation in the infarcted hearts. Regulation of macrophage polarization was implicated in myocardial infarction for the quality and outcome of cardiac healing...

BACKGROUND: Stem cell therapy was established as a promising approach for regenerative medicine applications such as cardiac repair. However, current stem cell-based therapeutic strategies have serious challenges such as low retention and viability of transplanted stem cells in the injured myocardium. This significantly limits efficiency of stem cell therapy. In addition, poor knowledge about the fate and survival of stem cells after transplantation represents a major reason of conflicting results from recent clinical studies...

Nicotine dependence has progressively become a foremost community health interest in the both developed and developing nations due to the economic burden and health-related problem. Smoking was significantly higher among patients with schizophrenia in comparison to the general population. Nicotine dependence is not only associated with public stress, but among patients with schizophrenia, smoking brings major challenges to the management. Nicotine may diminish the therapeutic efficacy of the bioavailability of the psychopharmacological agents in-vivo...

Abdominal aortic aneurysms (AAA) are life-threatening because of the potential for rupture, resulting in death. The current standard treatment for AAA is surgery, comprising laparotomic graft replacement and endovascular repair. However, because surgery carries the risk of major complications and re-intervention, medical therapies are desirable because they may reduce the occurrence of enlargement and rupture. Recent research shows that the progression of AAA is related to inflammatory reactions, especially those in the NF-kB pathway...

Prevention of stroke is a pivotal intervention in the management of patients with atrial fibrillation (AF) at increased risk of systemic embolism. Because of the difficulties of safely implementing Vitamin K Antagonists in all patients, there has been a growing interest in improving the pharmacological management of AF, with newer antithrombotic agents. The new oral anticoagulants (NOACs) have been developed to overcome the limitations and improve the efficacy of the conventional oral anticoagulant drugs. Among the NOACs, apixaban - a very specific antagonist of activated factor Xa - has pharmacokinetic and pharmacodynamic properties that allow significant efficacy in AF management...

Kok-Yong Chin, Wun Fui Mark-Lee
Mitragyna speciosa is a tropical plant with narcotic effects. The antinociceptive effects of its crude extracts, bioactive compounds and structurally modified derivatives have been examined in rodent models. This review aims to summarize the evidence on the antinociceptive effects of M. speciosa and its derivatives and explore whether they can offer an alternative to morphine in pain management. Methanolic and alkaloid extracts of M. speciosa were shown to attenuate the nociceptive response in rodents. Mitragynine and 7-hydroxymitragynine offered better antinociceptive effects than crude extracts...

Abdominal aortic aneurysms (AAA) are a major cause of death. Currently, the mainstay of treatment for AAA is surgical repair and there are no FDA approved medical therapies for AAA. Much research is in progress to discover new medical therapies for AAA. The pathophysiology of AAA is understood to be a complex interplay of inflammatory and proteolytic processes that degenerate the aneurysm wall. Arterial calcification, which is observed in AAA but to a lesser extent than in arterial occlusive disease, occurs in a highly regulated manner in a similar process as mineral deposition in bone...

Nicotine is one of the most abused substances worldwide and can cause several harmful effects on health. One of the harmful effects which is often ignored is osteoporosis. Smoking has been shown to cause a decrease in bone mineral density in humans. Animal studies have proven that nicotine exerts negative effects on bone. The number of people who smoke increases each day. Those who smoke starts at a very young age and they usually smoke for years. This will increase the risk of developing osteoporosis. As the prevalence of osteoporosis increases, the risk of fractures also increases...

Abdominal aortic aneurysm (AAA) is a degenerative disease that cause mortality in people aged > 65 years. Increased reactive oxygen species (ROS) and oxidative stress seems to play a pivotal role in AAA pathogenesis. Several sources of ROS have been identified in aortic tissues using experimental models: inflammation, increased activity of NAD(P)H or NOX, over-expression of inducible nitric oxide synthase (iNOS), uncoupled endothelial nitric oxide synthase (eNOS), platelets activation and iron release from hemoglobin...

Depression is a common psychiatric disorder that decreases the quality of life and increases the mortality of patients. It incurs significant healthcare costs if left untreated. Even though intervention with antidepressants can reduce depressive symptoms, side effects are often an issue and relapse is very common. Vitamin D, commonly known as the sunshine vitamin, is an essential fat-soluble vitamin for the absorption of calcium to prevent rickets (children) and osteomalacia (adults). Evidence on a possible relationship between vitamin D deficiency and depression is growing...

Cognitive function and testosterone level of men decline concurrently with aging. Low testosterone levels are associated with higher risk of Alzheimer's disease and mild cognitive impairment in men. There are continuous debates on whether this relationship is casual or causal. This paper aims to summarize the current evidence on the association between testosterone level and cognitive function in elderly men. The presence of testosterone, androgen receptor and its responsive genes hint that testosterone has biological functions in the central nervous system...

BACKGROUND: Particulate matter directly emitted into the air by sources such as combustion processes and windblown dust, or formed in the atmosphere by transformation of emitted gases are the major contributors to air pollution that triggers a diverse array of human pathologies including lung cancer. The mortality in lung cancer is usually high as the disease is not symptomatic at its early treatable stage. Moreover, available methods for screening are costly and mainly rely on imaging techniques which lack sufficient sensitivity and specificity...

Bacterial resistance to antibiotics is one of the most serious challenge to global public health. The introduction of new antibiotics in clinical settings, i.e. agents that belong to a new class of antibacterials, act on new targets or has a novel mechanisms of action, may not be sufficient to cope with the emergence of multidrug-resistant pathogens such as Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Klebsiella pneumoniae, Acinetobacter baumannii and Escherichia coli, which are increasingly prevalent in healthcare settings in Europe, the USA and Asia...

Heat shock proteins (HSPs) constitute a group of proteins that play crucial role in process of proteins folding. HSPs are also known to modulate number of key apoptotic factors. High expression of these proteins is reported in array of cancers, such as breast, prostate, colorectal, lung, ovarian, gastric, oral and esophageal cancer. Ample amount of investigations carried out on variety of cancers suggests HSPs as a promising hallmark in cancers. Their expression profile in several tumors elucidates that they help in proliferation, invasion, metastasis and death of cancerous cells...

Phytoestrogens has recently been claimed to positively influence menopausal discomforts, including hot flashes. However, little is known about the influence of phytoestrogens on core body temperature during estrogen fluctuation at menopause. With many published findings that phytoestrogens could relieve menopausal complaints, the present review was aimed at assessing the effects of phytoestrogens on thermoregulatory mechanism during menopausal transition. Thephytoestrogens of interest in relation to human health include isoflavones, lignans, coumestans and stilbenes, which are widely distributed within nature...
