During placental development, mononuclear cytotrophoblasts differentiate and fuse to syncytiotrophoblasts (STB) to form syncytia, which secrete human chorionic gonadotropin (hCG). Decreased maternal perfusion of the placenta, which leads to placental dysfunction, induces changes in trophoblast syncytialization. Our previous study showed that calreticulin (CRT), a Ca2+-binding molecular chaperone found in the endoplasmic reticulum, is expressed in the human placenta and is involved in regulating extravillous trophoblast invasion, although its role in villous trophoblasts remains unclear.

Background And Aims: Children with very early onset inflammatory bowel disease represent a unique cohort, often with a severe phenotype that is refractory to conventional medications, and in some cases, have underlying primary immunodeficiencies. Prior work has identified distinct histopathological patterns in the gastrointestinal tract in patients with primary immunodeficiencies. The aim of this study is to characterize the diagnostic histological findings in patients with VEO-IBD as compared to older onset pediatric IBD and determine if there are unique pathological changes that can shed light on the driving forces of the disease, particularly immunodeficiencies.

Different laboratory approaches have been exploited to analyze an effect of vitamin D supplements on T cell cytokine profiles in multiple sclerosis, with poorly reproducible results. We assessed the correlation between intra-cellular flowcytometry analysis of CD4 T cell-enriched CD3CD8 lymphocytes after PMA/ionomycin stimulation directly ex-vivo or after 72 h pre-stimulation with anti-CD3, and cytokine levels excreted in culture supernatants. Pre-stimulation with anti-CD3 resulted in higher proportions of cells positive for IFN-γ, IL-17 A, IL-4, IL-10 and GM-CSF (all P < 0. Read More

A major effort has been focused on the detection of oncogenes' mutations in diverse types of clinical specimens including formalin-fixed and paraffin embedded tissues, presently the gold-standard samples, up to plasma, that constitute a noninvasive alternative source of tumor DNA. The reliable detection of mutations in circulating tumor DNA requires a high analytical sensitivity. Here, we applied three different highly sensitive methodologies (COLD-PCR, a microarray-based approach and the droplet digital PCR, ddPCR) to identify mutations in the plasma of 30 metastatic colorectal cancer patients previously genotyped on tissue biopsy.

We aimed to review the epidemiologic literature examining lifestyle, metabolic risk factors, and blood-based biomarkers including multi-omics (genomics, proteomics, and metabolomics) and to discuss how these predictive markers can inform early diagnosis of pancreatic ductal adenocarcinoma (PDAC). A search of the PubMed database was conducted in June 2018 to review epidemiologic studies of (1) lifestyle and metabolic risk factors for PDAC, genome-wide association studies (GWAS), and risk prediction models incorporating these factors and (2) blood-based biomarkers for PDAC (conventional diagnostic markers, metabolomics, and proteomics). Prospective cohort studies have reported at least twenty possible risk factors for PDAC, including smoking, heavy alcohol drinking, adiposity, diabetes, and pancreatitis, but the relative risks (RR) and population attributable fractions of individual risk factors are small (mostly <10%).

Musculoskeletal injuries are the predominant group of injuries in healthcare professionals due to the physical demands of their work, such as the mobilization and positioning of the dependent patients. The management of this type of problem should take into account direct and indirect costs, such as periods of incapacity for work due to illness, hiring and training of new employees during periods of absence, reduced levels of productivity and the effects on production and quality of work.

Chronic livestock diseases cause large financial loss and affect animal health and welfare. Controlling these diseases mostly requires precise information on both individual animal and population dynamics to inform the farmer's decisions, but even successful control programmes do by no means assure elimination. Mathematical models provide opportunities to test different control and elimination options rather than implementing them in real herds, but these models require robust parameter estimation and validation.
