The chicken egg vitelline membrane (CEVM) is an important structure for the transmembrane transport of egg yolk components, protection of the blastodisc, and separation of egg white and egg yolk. In this study, the N-glycoproteome of the CEVM was mapped and analyzed in depth. Total protein of the CEVM was digested, and the glycopeptides were enriched by a hydrophilic interaction liquid chromatography microcolumn and identified by nano liquid chromatography/tandem mass spectrometry. A total of 435 N-glycosylation sites on 208 N-glycoproteins were identified in CEVM. Gene Ontology enrichment analysis showed that CEVM N-glycoproteins are mainly involved in the regulation of proteinases/inhibitors and transmembrane transport of lipids. Mucin-5B is the primary N-glycoprotein in the CEVM. Comparison of the main N-glycoproteins between the CEVM and other egg parts revealed the tissue specificity of N-glycosylation of egg proteins. The results provide insights into protein N-glycosylation in the chicken egg, CEVM functions and underlying mechanisms.This work deals with the submerged cultivation, extraction and antitumor activity of polysaccharides from Lentinus crinitus. The fungus was isolated from a tropical forest (Antioquia, Colombia), cultivated in laboratory conditions, and classified by classical and molecular taxonomy. Then, it was cultivated in a bioreactor of 5 L using a ligninolytic residue as substrate. The fermentation conditions were 30 ± 1 °C, pH 4.5, 300 rpm and 1.5 vvm for 4 days. The yields of fermentation were 20 g/L of biomass. After extraction, 0.65 g/L of water-soluble exopolysaccharide (LEPS) and 3.3 mg/100 g of water-soluble intrapolysaccharide (LIPS) were obtained. In each extract total carbohydrate, glucans and protein contents were determined. Also, scanning electron microscopy (SEM), Fourier transform infrared (FTIR), X-ray diffractometry (XRD), high performance liquid chromatography with refraction index detection (HPLC-RI) and high performance gel permeation chromatography (HPGPC) analysis for characterization were performed. The antitumor activity was evaluated and polysaccharides not only showed anti-proliferative activity in breast cancer cells but also they activate J774 macrophages as evidenced by the increase of nitric oxide and tumor necrosis factor-α (inducers of tumor cell apoptosis). Our findings suggest that polysaccharides can activate macrophages to release nitric oxide (NO) and tumor necrosis factor alpha (TNF-α), which directly blocks cancer cell growth. Puromycin order These findings enhance our knowledge about new sources of fungal metabolites that serve as coadjuvant, cheap and less harmful alternatives to cancer treatment.

We evaluated the efficacy and safety of diet-modulated autologous fecal microbiota transplantation (aFMT) for treatment of weight regain after the weight-loss phase.

In the DIRECT PLUS (Dietary Intervention Randomized Controlled Trial Polyphenols-Unprocessed) weight-loss trial (May 2017 through July 2018), abdominally obese or dyslipidemic participants in Israel were randomly assigned to healthy dietary guidelines, Mediterranean diet, andgreen-Mediterranean diet weight-loss groups. All groupsreceived free gym membership and physical activity guidelines. Both isocaloric Mediterranean groups consumed 28 g/d walnuts (+440 mg/d polyphenols provided). The green-Mediterranean dieters also consumed green tea (3-4 cups/d) and a Wolffia globosa (Mankai strain, 100 g/d) green shake (+800 mg/d polyphenols provided). After 6 months (weight-loss phase), 90 eligible participants (mean age, 52 years; mean weight loss, 8.3 kg) provided a fecal sample that was processed into aFMT by frozen, opaque, and odorless capsules. < .05).

Autologous FMT, collected during the weight-loss phase and administrated in the regain phase, might preserve weight loss and glycemic control, and is associated with specific microbiome signatures. A high-polyphenols, green plant-based or Mankai diet better optimizes the microbiome for an aFMT procedure. ClinicalTrials.gov number, NCT03020186.

Crohn’s disease (CD) is a chronic gastrointestinal disease resulting from the dysfunctional interplay between genetic susceptibility, the immune system, and commensal intestinal microbiota. Emerging evidence suggests that treatment by suppression of the immune response and replacement of the microbiota through fecal microbiota transplantation (FMT) is a promising approach for the treatment of CD.

We obtained stool metagenomes from CD patients in remission and assessed gut microbiome composition before and after FMT at the species and strain levels. Longitudinal follow-up evaluation allowed us to identify the gain, loss, and strain replacement of specific species and link these events to the maintenance of remission in CD.

We found that FMT had a significant long-term effect on patient microbial compositions, although this was primarily driven by the engraftment of donor species, which remained at low abundance. Thirty-eight percent of FMT-driven changes were strain replacements, emphasizing the importanstudies centered around the application of FMT and defined microbial communities as a therapeutic approach for treating CD.

Severe community-acquired pneumonia (SCAP) is a critical disorder with high morbidity and mortality, usually manifested as acute respiratory failure and septic shock generally caused by exaggerated systemic inflammation. Interleukin-32 (IL-32), a pro-inflammatory cytokine, has been reported involved in various infectious diseases. We investigated the efficacy of the plasma IL-32 as a biomarker for evaluating the severity and clinical outcomes in SCAP patients.

A total of 124 adult immunocompetent SCAP patients and 87 healthy controls were enrolled in this observational, prospective cohort study.

We found that PBMCs IL-32 mRNA and plasma IL-32 concentrations on admission of SCAP patients were significantly higher than healthy controls. Plasma IL-32 concentrations closely correlated with increasing severity scores, the need for vasopressor support or invasive mechanical ventilation but not with the etiology. The area under the curve (AUC) for predicting 30-day mortality using IL-32 was 0.812, is superior to WBCs and CRP.
