Microgliosis plays a critical role in diet-induced hypothalamic inflammation. A few hours after a high-fat diet (HFD), hypothalamic microglia shift to an inflammatory phenotype, and prolonged fat consumption leads to the recruitment of bone marrow-derived cells to the hypothalamus. However, the transcriptional signatures and functions of these cells remain unclear.

Background: Students´ assessment should be carried out in an effective and objective manner, which reduces the possibility of different evaluators giving different scores, thus influencing the qualification obtained and the consistency of education. The aim of the present study was to determine the agreement among four evaluators and compare the overall scores awarded when assessing portfolios of endodontic preclinical treatments performed by dental students by using an analytic rubric and a numeric rating scale.

Methods: A random sample of 42 portfolios performed by fourth-year dental students at preclinical endodontic practices were blindly assessed by four evaluators using two different evaluation methods: an analytic rubric specifically designed and a numeric rating scale.

Background: The aim of this study was to determine the influence of the gingival margin position and the adhesive strategy selected to perform deep margin elevation (DME) in marginal sealing of resin composite inlays by a nanoleakage test.

Material And Methods: 12 sound third molars were selected and expulsive MOD cavities for inlays were prepared. Experimental groups were established according to gingival margin location (enamel: 1 mm above cemento-enamel junction (CEJ), dentin: 1 mm below CEJ, or DME, and the adhesive strategy used to lute inlays and elevate the gingival margin.

Aims: To assess the strength and electrical activity of the pelvic floor muscles (PFMs) of male-to-female transgender individuals submitted to gender-affirming surgery (GAS).

Methods: A case series study was conducted from October 2016 to August 2018. Transgender women, who were scheduled for GAS, participated in the study.

Zinc is a key component of several proteins, interacting with the pancreatic hormones insulin and amylin. The role of zinc in insulin oligomerization and crystallinity is well established, although the effects of dietary zinc restriction on both energetic metabolism and β-pancreatic hormonemia and morphology remain unexplored. Here we report the effects of dietary zinc restriction on the endocrine pancreas and metabolic phenotype of mice.

The chromatoid body is a cytoplasmic male germ cell structure that plays a role in the regulation of mRNA transcription during spermatogenesis. A proteomic analysis of this structure has identified the presence of its classic molecular markers (MVH and MIWI), as well as a significant number of transient proteins. Circadian locomotor output cycles protein kaput (CLOCK) and brain and muscle ARNT-like 1 (BMAL1), which are molecular components of the circadian clock, are likely located in the chromatoid body in a transient fashion.

Since the discovery of amylin its use has been discouraged by the inadequacy of the protocol involving multiple injections in addition to insulin. We aimed here to develop a combined fixed-dose formulation of pramlintide with fast-acting insulin. We have investigated the compatibility of regular and fast-acting insulin analogues (Aspart, Asp, and LisPro, LysPro) with the amylin analogue pramlintide by using electrospray ionization - ion mobility spectrometry-mass spectrometry (ESI-IMS-MS), kinetic aggregation assays monitored by thioflavin T, and transmission electron microscopy (TEM) in the evaluation of the aggregation product.

Amylin is a pancreatic peptide hormone co-secreted along with insulin by the β-cells. It is found in amyloid deposits in both type 2 diabetic individuals and elder non-diabetic. The triple proline amylinomimetic compound (25,28,29-Pro-human amylin) named pramlintide was designed aiming to solve the solubility and amyloid characteristics of human amylin.

Article Synopsis
  • A one-year study at Embrapa Beef Cattle in Campo Grande, Brazil, identified various tick species on both wild and domestic animals, collecting a total of 323 ticks from 55 wild hosts.
  • Amblyomma cajennense was the most common tick found, residing on multiple species except capuchin monkeys, while the giant anteater had the highest tick infestation.
  • The findings highlight A. cajennense as a key vector for pathogens between wild and domestic animals in the Cerrado ecosystem.
