Changing Development Factor-β1, Arterial Firmness and Vascular Age in People With Unrestrained Arterial Blood pressure.
The phenotype/genotype relationship of patients with transfusion-dependent thalassaemia (TDT) is particularly complex and variable, thus generating different levels of severity and of annual transfusion volume (ATV). In this study, we explored the role and the contribution of several factors potentially involved in determining mean ATV in a cohort of TDT patients which have been followed since long time. We collected data on one-hundred and twenty-seven patients with transfusion-dependent β-thalassaemia followed at Rare Blood Cell Disease Unit, AORN Cardarelli Hospital. Age at first transfusion, genotype, spleen status (splenectomy or not), and mean soluble transferrin receptor (sTfR) were the parameters included in the analysis. At stepwise regression analysis which included all the parameters, only splenectomy and mean sTfR significantly predicted the mean ATV (F = 70.94, P  less then  0.0001, R2 = 0.540). Overall, our data may suggest that in patients with TDT, the measurement of sTfR level together with the spleen status could contribute, more accurately than genotype, to provide a basal evaluation of residual erythropoietic activity and mean ATV.Acute myeloid leukemia (AML) represents the most common indication for allogeneic hematopoietic cell transplantation (HCT). This study aimed to address the implementation status of allogeneic HCT for adults with AML in Japan and to provide a comprehensive overview of post-transplant outcomes. For this purpose, we analyzed data of 15,186 patients undergoing allogeneic HCT between 1992 and 2016 who were consecutively reported to the Japanese nationwide transplantation registry. The constant increase in the annual number of transplantations was clearly attributable to the growth of unrelated transplantation, and umbilical cord blood transplantation currently accounts for one-third of all allogeneic HCTs. The proportion of older patients has increased steadily since 2000, approximately, in parallel with the introduction of reduced-intensity conditioning. The probability of overall survival (OS) was estimated at 41% (95% confidence interval (CI), 40-42%) for the entire cohort, 56% (95% CI, 55-57%) for patients transplanted in complete remission (CR), and 22% (95% CI, 21-23%) for those transplanted in non-CR. Multivariate analysis identified age, sex, performance status, disease status, cytogenetic risk, donor type, graft source, sex mismatch between the donor and the recipient, and year of transplantation as factors significantly associated with OS. These findings represent the real-world data in Japan, showing the changes in transplantation practice and a detailed estimation of post-transplant outcomes.Sickle cell anemia (SCA) is the most severe form of sickle cell disease caused by homozygosity of the βS-gene (S/S or βSβS) and has worldwide distribution. Six polymorphic sites in the β-globin gene cluster were analyzed from a sample of 56 chromosomes of patients with SCA from the state of Maranhão, northeastern Brazil. PCR-RFLP showed that the CAR haplotype was predominant with a frequency of 64.28%, followed by the BEN haplotype (28.57%). Atypical haplotypes were identified at a frequency of 7.15%. Genotypes CAR/CAR, BEN/BEN, and CAR/BEN were present in 46.43%, 10.71%, and 35.71% of patients, respectively. β-Globin haplotype determination is important not only for the monitoring and prognosis of patients with SCA, but it also serves to inform anthropological studies that contribute to elucidating any peculiarities associated with African influences that contributed to the ethnological, economic, cultural, and social formation of Brazil. The high frequency of the CAR/CAR and CAR/BEN haplotypes in this study, which are associated with low levels of fetal hemoglobin, may ultimately reflect a severe clinical course and poor prognosis in patients with SCA in Maranhão.Preclinical evidence on the role of glucagon-like peptide-1 receptor (GLP-1r) agonists in the brain led to an increased interest in repurposing these compounds as a therapy for central nervous system (CNS) disorders and associated comorbidities. We aimed to investigate the neuroprotective effects of acute treatment with exendin (EX)-4, a GLP-1r agonist, in an animal model of inflammation. We evaluated the effect of different doses of EX-4 on inflammatory, neurotrophic, and oxidative stress parameters in the hippocampus and serum of lipopolysaccharide (LPS)-injected animals. Male Wistar rats were injected with LPS (0.25 mg/kg i.p.) and treated with different doses of EX-4 (0.1, 0.3, or 0.5 μg/kg i.p.). Sickness behavior was assessed by locomotor activity and body weight, and depressive-like behavior was also evaluated using forced swim test (FST). Brain-derived neurotrophic factor (BDNF), thiobarbituric acid reactive species (TBARS), and interleukin (IL)-6 were quantified in the serum and hippocampus. Glycemia was also analyzed pre- and post-EX-4 treatment. LPS groups exhibited decreased frequency of crossing and reduced body weight (p  0.05). Our study provides evidence on acute anti-inflammatory effects of EX-4 in the hippocampus of rats injected with LPS, contributing to future studies on repurposing compounds with potential neuroprotective properties.Solute carrier proteins (SLC) are essential membrane transport proteins responsible for transporting lipids, amino acids, sugars, neurotransmitters, and drugs across the biological membranes. Dysfunction of these carrier proteins may lead to an imbalance of biological mechanisms and also in the failure of the transporting pathways of several signaling neurotransmitters. In the present study, a 646 bp of a solute carrier protein (SLC15A4) was cloned and sequenced from the Indian white shrimp, Penaeus indicus. Multiple sequence alignment using ClustalW and phylogenetic analysis of putative SLC15A4 fragment from P. indicus (PiSLC15A4) was performed using Mega X tool. Tissue distribution analysis was carried out using real-time PCR. The differential expressions of PiSLC15A4 were also analyzed in the ovaries and brain tissues of wild-caught female shrimps at different maturation stages and in the brain tissues of captive females subjected to induce maturation by eyestalk ablation.
