Fleshy fruit ripening is typically regulated by ethylene in climacteric fruits and abscisic acid (ABA) in non-climacteric fruits. Common fig (Ficus carica) shows a dual-ripening mechanism, which is not fully understood. Here, we detected separate peaks of ethylene and ABA in fig fruits at the onset- and on-ripening stages, in conjunction with a sharp rise in glucose and fructose contents. In a newly-designed split-fruit system, exogenous ethylene failed to rescue fluridone-inhibited fruit ripening, whereas exogenous ABA rescued 2-amino-ethoxy-vinyl glycine (AVG)-inhibited fruit ripening. Transcriptome analysis revealed changes in the expression of genes key to both ABA and ethylene biosynthesis and perception during fig fruit ripening. At the de-greening stage, downregulation of FcACO2 or FcPYL8 retarded ripening, but downregulation of FcETR1/2 did not; unexpectedly, downregulation of FcAAO3 promoted ripening, but it inhibited ripening only before the de-greening stage. Furthermore, we detected an increase in ethylene emissions in the FcAAO3-RNAi ripening fruit and a decrease in ABA levels in the FcACO2-RNAi unripening fruit. Importantly, FcPYL8 can bind to ABA, suggesting that it functions as an ABA receptor. Our findings support the hypothesis that ethylene regulates the fig fruit ripening in an ABA-dependent manner. We propose a model for the role of the ABA-ethylene interaction in climacteric/non-climacteric processes.Pulmonary arterial hypertension (PAH) is a progressive cardiovascular disease with high mortality. However, there were no efficient medical drugs for PAH to enormously improve the survival and quality of life measures. The present study aimed to explore the protective effect of baicalin against experimental PAH in vivo and vitro. All the experimental rats received intraperitoneal injection of monocrotaline (MCT) to induce PAH model. Baicalin was given by intragastric administration from 2 days after MCT injection. Forty animals were randomly divided into four groups Control, MCT, saline-, and baicalin-treated groups (n = 10 in each). Post-operation, hemodynamic data, and index of right ventricular hypertrophy (RVHI) were recorded to evaluate the inhibition of baicalin on MCT-induced PAH. Furthermore, pulmonary artery smooth muscle cells (PASMCs) model induced by tumor necrosis factor-α (TNF-α) was used to observe the inhibition of vascular cells proliferation in vitro. The results demonstrated that baicalin significantly attenuated MCT-induced right ventricular systolic pressure (RVSP), the index of right ventricular hypertrophy, and vessel wall thickness; inhibit inflammatory and cell proliferation induced by MCT or TNF-α, respectively. In addition, we found that baicalin might protect against experimental PAH via regulating the TNF-α/BMPR2 signaling pathway.

Lupus nephritis (LN) predicts a 9-fold higher atherosclerosis cardiovascular disease (ASCVD) risk, highlighting the urgent need to target ASCVD prevention. Studies in IgA nephropathy reported that severe renal arteriosclerosis (r-ASCL) in diagnostic biopsies strongly predicted ASCVD risk. We recently found that 50% of LN pathology reports overlooked r-ASCL reporting, which could explain prior negative LN ASCVD risk studies. Therefore, we aimed to examine associations between a composite of reported and over-read r-ASCL and ASCVD events in LN.

Data were abstracted from all LN patients who underwent diagnostic biopsy between 1994-2017 including demographics, ASCVD risk factors, and pathology reports at the time of LN diagnosis. We manually validated all incident ASCVD events. We over-read 25% of the biopsies to grade r-ASCL using Banff criteria. We supplemented the over-read r-ASCL grade, when available, to determine the composite of reported and over-read r-ASCL grade.

Among 189 incident LN patients, 78% were female, 73% white, and the median age was 25. Overall, 31% had any reported r-ASCL, and 7% had moderate-severe r-ASCL. After incorporating systematically re-examined r-ASCL grade, the prevalence of any and moderate-severe r-ASCL increased to 39% and 12%. We found 22 incident ASCVD events over 11 years of follow-up. Using a composite of reported and over-read r-ASCL grade, we found that severe r-ASCL in diagnostic LN biopsies was associated with 9-fold higher odds of ASCVD.

Severe r-ASCL can predict ASCVD in LN, therefore, larger studies are required to systematically report r-ASCL and examine ASCVD associations.

This results in the clonal expansion of myeloid blasts within the bone marrow and peripheral blood. The incidence of AML increases with age, and in childhood, AML accounts for 20% of all leukaemias. Whilst there are many clinical and biological similarities between paediatric and adult AML with continuum across the age range, many characteristics of AML are associated with age of disease onset. These include chromosomal aberrations, gene mutations and differentiation lineage. Following chemotherapy, AML cells that survive and result in disease relapse exist in an altered chemoresistant state. Molecular profiling currently represents a powerful avenue of experimentation to study AML cells from adults and children pre- and postchemotherapy as a means of identifying prognostic biomarkers and targetable molecular vulnerabilities that may be age-specific. This review highlights recent advances in our knowledge of the molecular profiles with a focus on transcriptomes and metabolomes, leukaemia stem cells and chemoresistant cells in adult and paediatric AML and focus on areas that hold promise for future therapies.

Polydioxanone (PDO) threads, poly-L-lactic acid (PLLA) threads, and polycaprolactone (PCL) threads have been used for lifting and antiaging purposes. The new PCL threads that have less residual monomer compared to the previous PCL are developed.

The efficacy of threads regarding collagen synthesis and wrinkle improvement was evaluated in vivo model.

In this study, threads were inserted into 30 six-week-old male SKH-1 hairless mice. One of four threads was implanted at either side of the spine of each mouse. Biopsy specimens obtained at 1, 4, and 8weeks were examined using hematoxylin and eosin (H&E) and Herovici's stain. Additionally, immunoblot analysis was performed using primary antibody for collagen type III and transforming growth factor-β (TGF-β) and visualized by chemiluminescence and densitometric quantification. Finally, skin replicas were used to calculate total wrinkle area (mm

).

Neocollagenesis was significantly increased by 50% in the new PCL and pre-existing PCL groups at 8weeks (p value<0.001). Additionally, new-PCL-implanted mice showed a significant increase in collagen type III and TGF-β expressions at 8weeks (p value<0.001). The number of inflammatory cells was also increased in the skin of PCL-implanted mice at 8weeks. Finally, wrinkles were reduced about 20% in the new PCL group at 8weeks.

The new PCL thread exhibited a superior skin rejuvenation effect. This suggests that the material processing technology can be applied not only to the thread but also to various products such as dermal filler and cosmetics.

Type2 diabetes mellitus is a group of metabolism abnormalities in carbohydrates and energy. Our aim was to investigate resting energy expenditure (REE) and blood glucose changes after biliary diversion in mice with diabetes.

Male mice with diabetes were randomly divided into biliary diversion and sham groups. REE was detected by indirect calorimetry, the levels of fasting blood glucose, total bile acids and triiodothyronine were analyzed. After mice were killed, the weight amount of brown adipose tissue (BAT) and gastrocnemius was measured, and the expression level of Gprotein-coupled bile acid receptor and type2 iodothyronine deiodinase in BAT and gastrocnemius were examined.

The two groups of mice were pair-fed, the bodyweights (P<0.001) and the fasting blood glucose level (P<0.001) in the biliary diversion group significantly decreased 24weeks after surgery. The intraperitoneal glucose tolerance test (P=0.035) and oral glucose tolerance test (P=0.027) showed improvement in glucose tolerance after surgery. The REE level significantly increased 24weeks after surgery (P=0.005), the levels of total bile acids (P=0.014) and triiodothyronine (P<0.001) increased at the 24th postoperative week. The weight ratio of BAT (P=0.038) and gastrocnemius (P=0.026) in the biliary diversion group were higher than that in the sham group. The expression of Gprotein-coupled bile acid receptor in BAT (P<0.001) and gastrocnemius (P=0.003) were upregulated after surgery, and the type2 iodothyronine deiodinase expression also increased in BAT (P=0.015) and gastrocnemius (P=0.015).

The REE level increased and the glucose metabolism improved in mice with diabetes after biliary diversion.

Human coagulation factor (F) XI deficiency, a defect of the contact activation system, protects against venous thrombosis, stroke, and heart attack, whereas FXII, plasma prekallikrein, or kininogen deficiencies are asymptomatic. FXI deficiency, inhibition of FXI production, activated FXI (FXIa) inhibitors, and antibodies to FXI that interfere with FXI/FXII interactions reduce experimental thrombosis and inflammation. FXI inhibitors are antithrombotic in patients, and FXI and FXII deficiencies are atheroprotective in apolipoprotein E-deficient mice.

Investigate the effects of pharmacological targeting of FXI in experimental models of atherogenesis and established atherosclerosis.

Low-density lipoprotein receptor-knockout (Ldlr

) mice were administered high-fat diet (HFD) for 8weeks; concomitantly, FXI was targeted with anti-FXI antibody (14E11) or FXI antisense oligonucleotide (ASO). 14E11 and FXI-ASO reduced atherosclerotic lesion area in proximal aortas when compared with controls, and 14E11 also reduced aortic sinus lesions. In an established disease model, in which therapy was given after atherosclerosis had developed, Ldlr

mice were fed HFD for 8weeks and then administered 14E11 or FXI-ASO weekly until 16weeks on HFD. In this established disease model, 14E11 and FXI-ASO reduced atherosclerotic lesion area in proximal aortas, but not in aortic sinus. Selleckchem Eprosartan In cultures of human endothelium, FXIa exposure disrupted VE-Cadherin expression and increased endothelial lipoprotein permeability. Strikingly, we found that 14E11 prevented the disruption of VE-Cadherin expression in aortic sinus lesions observed in the atherogenesis mouse model.

Pharmacological targeting of FXI reduced atherogenesis in Ldlr

mice. Interference with the contact activation system may safely reduce development or progression of atherosclerosis.
