The Indigenous people of Australia face significant health gaps compared with the general population, with lower life expectancies, higher rates of death, and chronic illness occurring more often than in non-indigenous Australians. Cancer is the second largest contributor to the burden of disease with breast cancer being the most common invasive cancer diagnosed for females. Despite a lower breast cancer incidence compared with non-indigenous women, fatalities occur at an elevated rate and breast cancers have an earlier age of onset...

INTRODUCTION: Nigeria which constitutes just one percent of the world population, accounts for 13% of the world maternal and under-five mortality. Utilization of health care services has been an important determinant of maternal and child outcomes. The vast majority of maternal and child deaths could be prevented if women utilize the available life lines. The study objective was to determine utilization of maternal and child health care services among women of child bearing age in Western Nigeria...

Antimicrobial peptides (AMPs) have the ability to penetrate the cell membrane, form pores which eventually lead to cell death. Immobilization of AMP on nanoparticles can play a major role in antimicrobial materials, biosensors for pathogen detection and in food safety. The minimum inhibitory concentration (MIC) of free Cecropin P1 (CP1, sequence SWLSTAKKLENSAKKRLSEGIAIAIQGGPR) and adsorbed on silica nanoparticle against E. coli O157:H7 EDL933 were 0.78μg/ml. This was found to be consistent with preservation of α-helical secondary structure of CP1 upon adsorption as indicated by circular dichroism (CD)...

Cervical cancer is one of the most common female malignancies worldwide. Liquiritin (LT), a major constituent of Glycyrrhiza Radix, possesses a variety of pharmacological activities, including anti-cancer, anti-oxidative, anti-inflammatory and neuro-protective effects. However, its role in human cervical cancer remains to be elusive. In our study, we found that LT suppressed cervical cancer cell migration, invasion and cloning ability with little cytotoxicity to human normal cells. In addition, apoptosis was induced by LT in cervical cancer cells through activation of Caspase-3 and poly ADP-ribose polymerase (PARP) cleavage...

Breast cancer is an important cancer among solid organ transplant recipients. While the incidence of breast cancer in solid organ transplant recipients is comparable to the age matched general population, the outcomes are generally poor. Interventions such as cancer screening which preclude the development of late stage disease through early detection are not well-studied, and clinical practice guidelines for cancer screening rely solely on recommendations from the general population. Among those with a prior breast cancer history, disease recurrence after transplantation is a rare but fearful event...

Endoscopic variceal ligation plus beta-blockers (EVL+BB) is currently recommended for variceal rebleeding prophylaxis, a recommendation that extends to all patients with cirrhosis with previous variceal bleeding irrespective of prognostic stage. Individualizing patient care is relevant and, in published studies on variceal rebleeding prophylaxis, there is a lack of information regarding response to therapy by prognostic stage. This study aimed at comparing EVL plus BB with monotherapy (EVL or BB) on all-source rebleeding and mortality in patients with cirrhosis and previous variceal bleeding stratified by cirrhosis severity (Child A vs...

Oxidative conditions of the eye could contribute to retinal cells loss through activating the Fas-L/Fas pathway. This phenomenon is one of the leading causes of some ocular diseases like age-related macular degeneration (AMD). By targeting proteins at their mRNA level, microRNAs (miRNAs) can regulate gene expression and cell function. The aim of the present study is to investigate Fas targeting by miR-374a and find whether it can inhibit Fas-mediated apoptosis in primary human retinal pigment epithelial (RPE) cells under oxidative stress...

Lysosomal cathepsins were previously found to be involved in tumor necrosis factor-α (TNFα)-induced apoptosis. However, there are opposing views regarding their role as either initiators or amplifiers of the signaling cascade as well as the order of molecular events during this process. In this study, we investigated the role of cathepsin D (catD) in TNFα/cycloheximide-induced apoptosis in U937 human monocytic cells. TNFα-induced apoptosis proceeds through caspase-8 activation, processing of the pro-apoptotic molecule Bid, mitochondrial membrane permeabilization, and caspase-3 activation...

Cardiomyopathy is the most severe outcome of Chagas disease, causing over 12,000 deaths/year. Immune cells participate in cardiomyopathy development either by direct tissue destruction, or by driving inflammation. We have shown that CD4-CD8- (double negative - DN) T cells are major sources of inflammatory and anti-inflammatory cytokines, associated with the cardiac (CARD) and indeterminate (IND) forms of Chagas disease, respectively. Here, we sought to identify Trypanosoma cruzi derived components that lead to activation of DN T cells in Chagas patients...

Cryptorchidism or undescended testis (UDT) is a common congenital abnormality associated with increased risk for developing male infertility and testicular cancer. This study elucidated the effects of endogenous ghrelin or growth hormone secretagogue receptor (GHSR) deletion on mouse reproductive performance and evaluated the ability of ghrelin to prevent testicular damage in a surgical cryptorchid mouse model. Reciprocal matings with heterozygous/homozygous ghrelin and GHSR knockout mice were performed. Litter size and germ cell apoptosis were recorded and testicular histological evaluations were performed...

Latin Americans are highly heterogeneous regarding the type of Native American ancestry. Consideration of specific associations with common diseases may lead to substantial advances in unraveling of disease etiology and disease prevention. Here we investigate possible associations between the type of Native American ancestry and leading causes of death. After an aggregate-data study based on genome-wide genotype data from 1805 admixed Chileans and 639,789 deaths, we validate an identified association with gallbladder cancer relying on individual data from 64 gallbladder cancer patients, with and without a family history, and 170 healthy controls...

Pancreatic β-cell death and dysfunction contributes to the pathogenesis of both type 1 and type 2 diabetes. We aimed to examine whether the regulator of G protein signaling protein 2 (RGS2), a multifunctional inhibitor of G protein-coupled receptor (GPCR) signaling, impacts β-cell death and function. Metabolic phenotypes, β-cell secretory function, and glucose and insulin tolerance were measured in RGS2 knockout (RGS2(-/-)) mice and their wild-type (RGS2(+/+)) littermate controls. β-Cell death was evaluated in RGS2-knockdown and -overexpressing β cells and RGS2(-/-) islets by flow cytometry, western blot, ELISA, TUNEL staining, and apoptosis RT(2) profiler PCR array analysis...

Statins are a well-established family of drugs that lower cholesterol levels via the competitive inhibition of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR). In addition, the pleiotropic anti-inflammatory effects of statins on T cells make them attractive as therapeutic drugs in T-cell-driven autoimmune disorders. Since statins do not exclusively target HMGCR and thus might have varying effects on different cell types, we generated a new mouse strain allowing for the tissue-specific deletion of HMGCR...

Each year, the global tobacco epidemic kills an estimated 6 million persons worldwide, including 600,000 who die from secondhand smoke exposure. If current trends continue, it is estimated that by 2030 tobacco use will result in approximately 8 million deaths worldwide annually; an estimated 80% of these preventable deaths will occur in low- and middle-income countries (1).

Tobacco use is the world's leading cause of preventable morbidity and mortality, resulting in nearly 6 million deaths each year (1). Smoked tobacco products, such as cigarettes and cigars, are the most common form of tobacco consumed worldwide (2), and most tobacco smokers begin smoking during adolescence (3). The health benefits of quitting are greater for persons who stop smoking at earlier ages; however, quitting smoking at any age has health benefits (4). CDC used the Global Youth Tobacco Survey (GYTS) data from 61 countries across the six World Health Organization (WHO) regions from 2012 to 2015 to examine the prevalence of current tobacco smoking and desire to quit smoking among students aged 13-15 years...

This study investigates suicide and overdoses in 1119 consecutive patients (64% women), 15 to 34 years of age, presenting at the emergency department after self-poisoning from1994 to 2000 and followed regarding death up to 2006. Regression and Kaplan-Meier survival analyses were performed for suicide and other causes of death. The patients had about a 60 times higher risk (SMR = 61.95) of death due to suicide and 26 times higher (SMR = 26.47) for all-cause mortality. Men had a nearly two times higher risk for suicide than women and half of the suicides occurred during the first two years after admission...

Myocardial infarction (MI) is a major cause of death and disability worldwide. The incidence is not expected to diminish, despite better prevention, diagnosis and treatment, because of the ageing population in industrialized countries and unhealthy lifestyles in developing countries. Nowadays it is highly requested an imaging tool able to evaluate MI and viability. Technology improvements determined an expansion of clinical indications from coronary plaque evaluation to functional applications (perfusion, ischemia and viability after MI) integrating additional phases and information in the mainstream examination...

Tissue-type plasminogen activator (tPA) is the only treatment for ischemic stroke. However, tPA could induce the intracranial hemorrhage (ICH), which is the main cause of death in ischemic stroke patient after tPA treatment. At present, there is no treatment strategy to ameliorate tPA-induced brain injury after ischemia. Therefore, we investigated the effect of pre-treated isoflurane, which is a volatile anesthetic and has beneficial effects on neurological dysfunction, brain edema and infarct volume in ischemic stroke model...
