The distribution and public health significance of Cryptosporidium species and genotypes in humans and bovine differ across geographical areas. Cryptosporidium species causes a disease known as cryptosporidiosis in humans and animals. To characterize the prevalence of cryptosporidiosis in humans in southern Assam, India, stool samples (n = 1119) of diarrhea patients were collected from different hospitals and from the community during the period January 2014 to July 2016. Fecal smears were examined microscopically for Cryptosporidium species using modified acid fast staining and were screened to ascertain the presence of Cryptosporidium antigen by enzyme-linked immunosorbent assay (ELISA)...

Breast cancer ranks first in incidence and mortality in working age women. Cancer initiation and progression relies on accumulation of genetic and epigenetic aberrations that alter cellular processes, among them, epithelial to mesenchymal transition (EMT) denotes particularly aggressive neoplasias given its capacity to invade and metastasize. Several microRNAs (miRNA) have been found able to regulate gene expression at the core of EMT. In this study, the Affymetrix CytoScan HD array was used to analyze three different primary tumor cell isolates from Mexican breast cancer patients...

Antiplatelet therapy reduces the risk of myocardial infarction, stroke, and vascular death in patients who have symptomatic peripheral artery disease. However, a subset of patients who take aspirin continues to have recurrent cardiovascular events. There are few data on cardiovascular outcomes in patients with peripheral artery disease who manifest aspirin resistance. Patients with peripheral artery disease on long-term aspirin therapy (≥4 wk) were tested for aspirin responsiveness by means of the VerifyNow Aspirin Assay...

Although the SLE risk gene loci of HLA-DR and HLA-DQ within the major histocompatibility complex (MHC) region has been gradually revealed by recent Genome-Wide Association studies (GWAS), the association of HLA-DP polymorphisms with SLE was minimally reported. Considering that the variants in rs3077 and rs9277535 in the HLA-DP region could influence the immune response by affecting antigen presentation of HLA class II molecules to CD4(+) T cells, the present study aimed to explore the role of HLA-DP polymorphisms in SLE...

Nalfurafine is a moderately selective kappa opioid receptor (KOR) analgesic with low incidence of dysphoric side effects in clinical development for the treatment of uremic pruritis. The basis for its reduced dysphoric effect compared to other KOR agonists is not clear, but prior studies suggest that the aversive properties of KOR agonists require p38α MAPK activation through an arrestin-dependent mechanism. To determine whether nalfurafine is a functionally selective KOR agonist, we measured its potency to activate the G protein-dependent early phase of Extracellular Signal-Regulated Kinase (ERK1/2) phosphorylation and the arrestin-dependent late phase of p38 MAPK signaling...

BACKGROUND: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) caused by oncogenic human papillomavirus (HPV) is rising worldwide. HPV-OPSCC is commonly diagnosed by RT-qPCR of HPV E6 and E7 oncoproteins or by p16 immunohistochemistry (IHC). Droplet digital PCR (ddPCR) has been recently reported as an ultra-sensitive and highly precise method of nucleic acid quantification for biomarker analysis. To validate the use of a minimally invasive assay for detection of oncogenic HPV based on oropharyngeal swabs using ddPCR...

BACKGROUND AND PURPOSE: Neonatal hypoxic-ischemic encephalopathy (HIE) is one of the leading causes of neurological handicap in developing countries. Human umbilical cord blood (hUCB) CD34-positive (CD34⁺) stem cells exhibit the potential for neural repair. We tested the hypothesis that hUCB CD34⁺ stem cells and other cell types [leukocytes and nucleated red blood cells (NRBCs)] that are up-regulated during the acute stage of perinatal asphyxia (PA) could play a role in the early prediction of the occurrence, severity, and mortality of HIE...

Topical minoxidil is the only US FDA approved drug for the treatment of female pattern hair loss (FPHL). 5% minoxidil foam is only effective at re-growing hair in a minority of women (approximately 40%). Thus, the majority of FPHL patients remain untreated. Previously, we demonstrated that nonresponders to 5% minoxidil have low metabolism of minoxidil in hair follicles. As such, we hypothesized that increasing the dosage of topical minoxidil to low metabolizers would increase the number of responders without increasing the incidence of adverse events...

BACKGROUND: Clinical relevance of nontuberculous mycobacteria (NTM) is increasing worldwide including in Saudi Arabia. A high species diversity of NTM's has been noticed in a recent study. However, the identification in diagnostic laboratories is mostly limited to common species. The impact of NTM species diversity on clinical outcome is so far neglected in most of the clinical settings. METHODOLOGY/PRINCIPAL FINDINGS: During April 2014 to September 2015, a nationwide collection of suspected NTM clinical isolates with clinical and demographical data were carried out...
