The occurrence of convergent evolution is thought to stem from the three bee-symbiotic groups sharing a similar habitat, i.e., the bee gut. The causative factor underlying genomic reduction was postulated to be mutY, which was absent in all three groups. Here, a novel strain, BHWM-4T, isolated from the gut of Bombus ignites was studied using polyphasic taxonomy and classified as a new member of the L. kunkeei group. The strain was Gram-positive, facultative anaerobic, and rod-shaped. The 16S ribosomal RNA gene sequence and genome analysis revealed that strain BHWM-4T was clustered into the L. kunkeei group, forming a compact cluster with L.

Biochemical, chemotaxonomic, and genotypic data of strain BHWM-4T supports the proposal of a novel species, Lactobacillus bombintestini sp. nov., whose type strain is BHWM-4T (= KACC 19317 = NBRC 113067T).PURPOSE OF REVIEW This review presents the available data regarding efficacy of nutritional therapy, highlighting clinical decision points and a strategy for reintroduction of foods following an elemental diet for treatment of eosinophilic gastrointestinal disorders. RECENT FINDINGS Elemental and empiric elimination diets are highly effective treatments for eosinophilic gastrointestinal diseases. Standardization in the reintroduction phase, after utilizing the diet for disease remission, is lacking. Clinicians are confronted with multiple challenges regarding the best practice for food reintroduction and identification of potential dietary triggers including order of foods being challenged and duration between endoscopic procedures. Individualization is required for preference and adherence to optimize quality of life and treatment success for this burdensome and life altering immune driven gastrointestinal disorder. Age specific concerns for children, teenagers, and adults should be assessed using a patient centric approach.Polydatin, a natural product, is detected in many daily diets, such as grape juices and peanut. Autophagy regulation is recognized as a new potential strategy for cancer therapy, and previous studies demonstrated that polydatin showed remarkable anti-cancer ability. Nevertheless, the capability of polydatin to induce autophagy and its role in anti-osteosarcoma remains obscure. In this study, we investigated the anticancer effect of polydatin on human osteosarcoma cell line MG-63 and its underlying mechanism. Our results indicated that polydatin significantly inhibited proliferation of MG-63 cells in a dose- and time-dependent manner, and increased their apoptosis and autophagic flux. Further experiments showed that polydatin reduced the expression and phosphorylation (Y705) level of STAT3 (Signal transducer and activator of transcription 3), increased the expression of autophagy-related genes (Atg12, Atg14, BECN1, PIC3K3), and therewith triggered autophagic cell death in MG-63 cells. Of note, the cytotoxicity effect of polydatin was rescued by co-treatment with Colivelin (STAT3 activator), suggesting the dependency of MG-63 cells on STAT3 for survival in this process. Moreover, polydatin-triggered autophagy and apoptosis were remarkably reduced following exposure to autophagy inhibitor 3-methyladenine, while cell viability was increased. In conclusion, these data demonstrated that polydatin induced MG-63 cell death through inducing apoptosis, and autophagy which was mediated via the STAT3 signaling. Therefore, polydatin might be a potential clinical drug in the remedy of osteosarcoma.This study aims to investigate the efficacy of lipid induction in Scenedesmus abundans by adding the effluent from dark fermentation of biohydrogen production. Four sets of experiments were conducted control (sufficient nitrogen), nitrogen depletion, low concentration (0.3×) effluent addition, and high concentration (0.5×) effluent addition. The addition of low concentration effluent produced the highest biomass and lipid yields of 2.831&nbsp;g/L and 1.238&nbsp;g/L, corresponding to a lipid abundance of 43.72&nbsp;wt%. Furthermore, S. abundans had high removal efficiencies for volatile fatty acids in the effluent (formic acid 100%, acetic acid 100%, propionic acid 98%, lactic acid 84%, and butyric acid 68%), and this is the first study demonstrating the ability of S. abundans in using formic acid and lactic acid to produce biomass and lipids. These results show that S. abundans have great abilities in simultaneous reducing organic acids in the effluent and producing valuable metabolites.BACKGROUND AND OBJECTIVES The emergence of resistant strains of Cutibacterium acnes can limit the efficacy of currently approved antibiotics for acne. VB-1953 is a next-generation antibiotic that exerts a bactericidal effect on resistant C. acnes. In this study, we investigated the safety, tolerability, and efficacy of VB-1953 topical gel in patients with moderate to severe acne having clindamycin-resistant C. acnes. METHODS An investigator-initiated, open label, single-arm clinical study was conducted in patients with moderate to severe facial acne vulgaris showing poor or no response to previous clindamycin treatment. Nineteen subjects were enrolled in the study based on laboratory screening for the presence of clindamycin-resistant C. acnes in acne swab samples collected from patients. VB-1953 2% gel was applied on the entire face twice daily over 12&nbsp;weeks. The primary efficacy endpoints were absolute changes in inflammatory and noninflammatory lesion counts from baseline at week 12, while the secondary efreduced by (94.3 ± 1%; p  less then  0.05) within 12&nbsp;weeks of treatment with VB-1953. CONCLUSION These results indicate that VB-1953 topical gel can be a safe and effective therapy for moderate to severe acne with underlying resistant C. acnes in subjects who had not responded to previous antibiotic treatments.This study was carried out to investigate the effects of selenium-enriched probiotics (SP) supplementation on growth performance, oocysts shedding, intestinal lesions and antioxidant capacities, and mRNA gene expression of local Chinese yellow male chickens infected with Eimeria tenella. One-day-old 270 chickens were randomly assigned into five groups, each consisting of three replicates with 18 chickens per replicate. Chickens in the negative and positive controls (NC, PC, respectively) received basal diets only (0.11&nbsp;mg&nbsp;Se/kg), whereas the other groups were supplied basal diets with probiotics and designated as (P, 0.11&nbsp;mg&nbsp;Se/kg), sodium selenite (SS, 0.41&nbsp;mg&nbsp;Se/kg), and (SP, 0.41&nbsp;mg&nbsp;Se/kg) groups. At 21&nbsp;days of age, except the NC group, all other groups were infected by oral gavage with 1.5 × 104 sporulated E. tenella oocysts per chicken. Three chickens were randomly selected from each group for serum, liver, and cecal specimen collection. The results showed that P, SS, and SP had significant increase weight gain and feed intake.
