Paneth cells (PCs) are located at the base of small intestinal crypts and secrete the α-defensins, human α-defensin 5 (HD-5) and human α-defensin 6 (HD-6) in response to bacterial, cholinergic and other stimuli. The α-defensins are broad-spectrum microbicides that play critical roles in controlling gut microbiota and maintaining intestinal homeostasis. Inflammatory bowel disease, including ulcerative colitis and Crohn's disease (CD), is a complicated autoimmune disorder. The pathogenesis of CD involves genetic factors, environmental factors and microflora. Surprisingly, with regard to genetic factors, many susceptible genes and pathogenic pathways of CD, including nucleotide-binding oligomerization domain 2 (NOD2), autophagy-related 16-like 1 (ATG16L1), immunity-related guanosine triphosphatase family M (IRGM), wingless-related integration site (Wnt), leucine-rich repeat kinase 2 (LRRK2), histone deacetylases (HDACs), caspase-8 (Casp8) and X-box-binding protein-1 (XBP1), are relevant to PCs. As the underlying mechanisms are being unravelled, PCs are identified as the central element of CD pathogenesis, integrating factors among microbiota, intestinal epithelial barrier dysfunction and the immune system. In the present review, we demonstrate how these genes and pathways regulate CD pathogenesis via their action on PCs and what treatment modalities can be applied to deal with these PC-mediated pathogenic processes.
Prostate cancer (PCa) is one of the leading causes, globally, of cancer-related mortality. Previous studies have reported an inverse relationship between some food items or dietary patterns and prostate cancer risk. Polyphenols, as antioxidant and anti-inflammatory dietary components, have been associated with a reduced risk of PCa, whilst dietary indices such as total antioxidant capacity are good predictors of PCa risk.

The purpose of this study was to conduct a case-control study on the association between polyphenol intake and DTAC (dietary total antioxidant capacity) and PCa risk in men.

205 hospital-based controls and 97 newly diagnosed PCa patients were asked about their dietary intakes using a validated questionnaire. The polyphenol contents (flavonoids, lignans, stilbenes and phenolic acids) of foods and beverages were calculated. TAC was obtained using a comprehensive database consisting of the total antioxidant content of more than 3000 food and beverages. Logistic regression was used to determine the odds ratios (OR), with 95% confidence intervals (CI), of PCa according to categories of polyphenol intake and TAC.

When comparing the highest and the lowest tertile of total polyphenol (OR 0.12; 95% CI 0.03-0.41), lignans (OR 0.14; 95% CI 0.04-0.41), phenolic acids (OR 0.18; 95% CI 0.05-0.57) and some flavonoid subgroups intake including flavan-3-ols (OR 0.24; 95% CI 0.08-0.67), flavanones (OR 0.10; 95% CI 0.03-0.31) and flavones (OR 0.33; 95% CI 0.12-0.87), we observed a significant decreasing trend in the risk of PCa (p for trend<0.05).

The results suggest that the consumption of some polyphenols can significantly reduce the risk of PCa.

Sexual minority (SM) people experience significant stress associated with stigma, contributing to a higher rate of adverse health outcomes. Several known factors (eg, smoking) elevate risk of poor bone health, but to date little research has examined disparities in bone health among SM people. To address this, we analyzed sexual orientation differences in an available bone mineral density (BMD) cross-sectional dataset assessed via dual X-ray absorptiometry.

We combined the 2007 to 2008, 2009 to 2010, and 2013 to 2014 cycles of US National Health and Nutrition Examination Survey to examine sexual orientation-based differences in z-scored BMD in the proximal femur (greater trochanter and intertrochanter locations), bone mineral content (BMC) in the femur and spine, and osteoporosis risk among Lesbian/Gay (n = 53), Bisexual (n = 97), Same-Sex Experienced (n = 103), and Heterosexual (n = 2990) adults.

Sexual orientation-based disparities in bone mass were observed across all anatomical sites. This effect was due to differences between heterosexual and gay men and persisted in linear regressions after adjusting for risk factors. We found differences in femoral and femoral neck BMC in heterosexual and gay men (P = .02) and in femoral, femoral neck and spinal BMC between heterosexual and bisexual women (P = .05). Sexual orientation remained significant in BMC regressions.

Our findings suggest that SM men but not women are at greater risk for poor bone health relative to heterosexuals and this disparity is independent of the lifestyle and psychosocial risks included in our models.

The designed biocatalyst trypsiligase enables site-directed linkage of small-sized fluorescence dyes on the N terminus of integral target proteins located in the outer membrane of living cells through a stable native peptide bond. The function of the approach was tested by using the examples of covalent derivatization of the transmembrane proteins CD147 as well as the EGF receptor, both presented on human HeLa cells. Specific trypsiligase recognition of the site of linkage was mediated by the dipeptide sequence Arg-His added to the proteins' native N termini, pointing outside the cell membrane. The labeling procedure takes only about 5 minutes, as demonstrated for couplings of the fluorescence dye tetramethyl rhodamine and the affinity label biotin as well.The aim of this research was to test a novel in-vivo brain MRI analysis method that could be used in clinical cohorts to investigate cortical architecture changes in patients with Alzheimer's Disease (AD). Three cohorts of patients with probable AD and healthy volunteers were used to assess the results of the method. The first group was used as the "Discovery" cohort, the second as the "Test" cohort and the last "ATN" (Amyloid, Tau, Neurodegeneration) cohort was used to test the method in an ADNI 3 cohort, comparing to amyloid and Tau PET. #link# The method can detect altered quality of cortical grey matter in AD patients, providing an additional tool to assess AD, distinguishing between these and healthy controls with an accuracy range between good and excellent. These new measurements could be used within the "ATN" framework as an index of cortical microstructure quality and a marker of Neurodegeneration. Further development may aid diagnosis, patient selection, and quantification of the "Neurodegeneration" component in response to therapies in clinical trials.
