Lactiplantibacillus plantarum Y15 alleviate type 2 diabetes in mice via modulating gut microbiota and regulating NF-κB and insulin signaling pathway.

Probiotics have been used for the treatment of chronic metabolic diseases, including type 2 diabetes (T2D). However, the mechanisms of antidiabetic effects are not well understood. The object of this study is to assess the antidiabetic effect of Lactiplantibacillus plantarum Y15 isolated from Chinese traditional dairy products in vivo. Results revealed that L. plantarum Y15 administration improved the biochemical indexes related to diabetes, reduced pro-inflammatory cytokines, L. plantarum Y15 administration reshaped the structure of gut microbiota, decreased the abundance of LPS-producing, and increased short-chain fatty acids (SCFAs)-producing bacteria, which subsequently reduce the levels of lipopolysaccharide (LPS) and pro-inflammatory cytokines. L. plantarum Y15 administration also regulated the expressions of the inflammation and insulin signaling pathway-related genes. These results suggest that L. plantarum Y15 may serve as a potential probiotic for developing food products to ameliorate T2D.

Graphene quantum dots decorated with imatinib for leukemia treatment.

The use of graphene quantum dots as biomedical device and drug delivery system has been increasing. This nanoplatform of pure carbon has showed unique properties and showed to be safe for human use. The imatinib is a molecule designed to specifically inhibit the tyrosine kinase, used for leukemia treatment. In this study, we successfully decorated the graphene quantum dots (GQDs@imatinb) by a carbodiimide crosslinking reaction. The GQDs@imatinb were characterized by FTIR and AFM. The nanoparticles' in vitro behaviors were evaluated by cellular trafficking (internalization) assay and cell viability and apoptosis assays in various cancer cell lines, including suspension (leukemia) cells and adherent cancer cells. The results showed that the incorporation of the imatinib on the surface of the graphene quantum dots did not change the nanoparticles' morphology and properties. The GQDs@imatinb could be efficiently internalized and kill cancer cells via the induction of apoptosis. The data indicated that the prepared GQDs@imatinb might be a great drug nano-platform for cancer, particularly leukemia treatments.

Anterior scalene plane block at the superior trunk level relieves referred shoulder pain after liver radiofrequency ablation: a technical report.

We report the first case of using an anterior scalene plane block at the superior trunk level achieving phrenic nerve blockade to treat intolerable referred shoulder pain after liver Radiofrequency Ablation (RFA) of a diaphragm-abutting liver tumor despite prevention with a full-dose non-steroidal anti-inflammatory drug. The anterior scalene plane block rapidly alleviated pain without significant complications.

Effect of fermented soybean meal supplementation on some growth performance, blood chemical parameters, and fecal microflora of finishing pigs

This study evaluated the effect of fermented soybean meal (FSBM) supplementation on growth performance, meat quality, blood biochemical parameters, and fecal microflora of finishing pigs. Thirty-two crossbred pigs (Duroc × Landrance × Yorkshire) (66-day-old, 67.95±0.25 kg) were randomly allocated to two treatments and fed diets containing soybean meal and FSBM. The average daily gain (ADG), average daily feed intake (ADFI), feed conversion ratio (FCR), blood biochemical parameters, and meat quality index were measured. At the end of experiment, the fecal microflora of finishing pigs was analyzed with 16S rDNA techniques. Results revealed that pigs fed FSBM had a greater ADG and lower cooking loss relative to control group (basal diets). Compared with the control group, the triglyceride content in the serum of the group fed FSBM increased significantly, and the creatinine content in the serum decreased notably. Fermented soybean meal enhanced the abundance of Bacteroidetes, Prevotellaceae, Bcteroidales, Bacteroidia, but inhibited the growth of Firmicutes, Clostridia, Clostridiales, and Ruminococcaceae in the intestine of pigs. Therefore, we can speculate that FSBM may play an important role in animal production. Dietary FSBM supplementation may be beneficial to some aspects of growth performance and the diversity of fecal microflora in finishing pigs.(AU)

PSORS2 is due to mutations in CARD14.

Psoriasis is a common, immune-mediated genetic disorder of the skin and is associated with arthritis in approximately 30% of cases. Previously, we localized PSORS2 (psoriasis susceptibility locus 2) to chromosomal region 17q25.3-qter after a genome-wide linkage scan in a family of European ancestry with multiple cases of psoriasis and psoriatic arthritis. Linkage to PSORS2 was also observed in a Taiwanese family with multiple psoriasis-affected members. In caspase recruitment domain family, member 14 (CARD14), we identified unique gain-of-function mutations that segregated with psoriasis by using genomic capture and DNA sequencing. The mutations c.349G>A (p.Gly117Ser) (in the family of European descent) and c.349+5G>A (in the Taiwanese family) altered splicing between CARD14 exons 3 and 4. A de novo CARD14 mutation, c.413A>C (p.Glu138Ala), was detected in a child with sporadic, early-onset, generalized pustular psoriasis. CARD14 activates nuclear factor kappa B (NF-kB), and compared with wild-type CARD14, the p.Gly117Ser and p.Glu138Ala substitutions were shown to lead to enhanced NF-kB activation and upregulation of a subset of psoriasis-associated genes in keratinocytes. These genes included chemokine (C-C motif) ligand 20 (CCL20) and interleukin 8 (IL8). CARD14 is localized mainly in the basal and suprabasal layers of healthy skin epidermis, whereas in lesional psoriatic skin, it is reduced in the basal layer and more diffusely upregulated in the suprabasal layers of the epidermis. We propose that, after a triggering event that can include epidermal injury, rare gain-of-function mutations in CARD14 initiate a process that includes inflammatory cell recruitment by keratinocytes. This perpetuates a vicious cycle of epidermal inflammation and regeneration, a cycle which is the hallmark of psoriasis.

A North American study of adapalene-benzoyl peroxide combination gel in the treatment of acne.

A fixed-dose combination gel with adapalene 0.1% and benzoyl peroxide (BPO) 2.5% recently has been developed for the treatment of acne vulgaris. In this multicenter, randomized, double-blind, parallel-group, active- and vehicle-controlled study conducted at 60 centers in the United States, Puerto Rico, and Canada, we assessed the efficacy and safety of adapalene-BPO combination gel in comparison with adapalene and BPO monotherapies as well as the gel vehicle. Participants with moderate facial acne vulgaris (rated 3 on the 5-point investigator global assessment of acne severity scale) were recruited and randomized to receive once-daily treatment with adapalene-BPO combination gel, adapalene monotherapy, BPO monotherapy, or gel vehicle for 12 weeks. They were assessed for success rate (the percentage of participants with investigator global assessment of acne severity rated clear or almost clear) and percentage change in inflammatory lesion (IL), noninflammatory lesion (NIL), and total lesion counts. Of the 1668 participants enrolled, 1429 (85.7%) completed the study. At study end point, adapalene-BPO combination gel showed a significantly higher success rate (P < or = .006) and a greater percentage reduction in all acne lesion counts (P < or = .017) compared with the other treatment groups. A significant early treatment effect of adapalene-BPO combination gel at week 1 compared with adapalene monotherapy and vehicle also was observed for all lesion count reductions (P<.001). The safety of adapalene-BPO combination gel was comparable with adapalene and BPO monotherapies and vehicle. In a large clinical trial, the adapalene-BPO fixed-dose combination gel has shown superiority in efficacy compared with adapalene and BPO monotherapies and vehicle, with an early onset of efficacy and a good safety profile.
