Methods: Sixty-seven participants (thirty-three with IPF and thirty-four healthy subjects [control group]) were included.

Revealing the Satellite DNA History in and Characid Fish by Comparative Satellitomics.

Eukaryotic genomes are usually enriched in repetitive DNA sequences, which can be classified as dispersed or tandemly repeated elements. Satellite DNAs are noncoding monomeric sequences organized in a head-to-tail fashion that are generally located on the subtelomeric and/or pericentromeric heterochromatin. In general, a single species incorporates a diverse group of satellite DNA families, which collection is called satellitome.

Analyzing the influence of age and sex in Bothrops pauloensis snake venom.

Considerable heterogeneity and ontogenetic changes in venom composition have already been observed in different species of snakes within the Viperidae family. Since the venom of young and adult can cause distinct pathological effects and because the antivenom may be less effective in neutralizing envenoming by young snakes compared to adults, it is of paramount importance to understand the ontogenetic variation of snake venom. Thus, the present study aimed to analyze and compare the venom of Bothrops pauloensis snakes, searching for possible influences of ontogeny and sex in their biochemical and biological aspects.

Urological Complications Associated With Pyeloureterostomy Without Ipsilateral Nephrectomy in Renal Transplant Recipients.

The implications of ligating the native ureter without ipsilateral nephrectomy after primary kidney transplant pyeloureterostomy (PU) have been described previously. This single-center retrospective cohort study including 4,215 kidney transplants performed between February 2010 and December 2014, analyzed urological complications following primary (P-PU) and secondary (S-PU) pyeloureterostomy used to treat urological leaks (UL-PU) and ureteral stenosis (US-PU) without concomitant ipsilateral nephrectomy, in a large cohort of patients. There were 495 (11.

A Stentless Modified Lich-Gregoir Technique for Safe Early Bladder Catheter Removal in Living and Deceased Kidney Transplants.

Objectives: To describe a stentless modified Lich-Gregoir technique (mLG) for ureteroneocystostomy in renal transplantation (RT), with early bladder catheter (BC) removal (under 48 hours), and compare the postoperative results with those of the traditional technique (LG) with routine bladder catheter removal (4 to 5 days). The modification consists of maintaining a thin layer of detrusor fibers covering the bladder mucosa during dissection, which is incorporated into the anastomosis to reinforce the ureteroneocystostomy.

Materials And Methods: This retrospective cohort study compared the postoperative outcomes of 100 consecutive patients who underwent mLG with early removal of BC between October 2018 to November 2019 with those of a historical cohort of 165 consecutive patients transplanted using stentless LG and routine removal of BC, who underwent surgery between July 2017 and September 2018.

Methods: This is a 5-y follow-up post hoc analysis of a prospective trial including 288 patients who were randomized to receive a single 3-mg/kg dose of rabbit antithymocyte globulin, tacrolimus, everolimus (EVR), and prednisone (rabbit antithymocyte globulin/EVR, n = 85); basiliximab, tacrolimus, everolimus, and prednisone (basiliximab/EVR, n = 102); or basiliximab, tacrolimus, mycophenolate, and prednisone (basiliximab/mycophenolate, n = 101).

Magnitude of the 8.2 ka event freshwater forcing based on stable isotope modelling and comparison to future Greenland melting.

The northern hemisphere experienced an abrupt cold event ~ 8200 years ago (the 8.2 ka event) that was triggered by the release of meltwater into the Labrador Sea, and resulting in a weakening of the poleward oceanic heat transport. Although this event has been considered a possible analogue for future ocean circulation changes due to the projected Greenland Ice Sheet (GIS) melting, large uncertainties in the amount and rate of freshwater released during the 8.

Is There Sufficient Evidence Justifying Limited Access of Jehovah's Witness Patients to Kidney Transplantation?

Background: Jehovah's Witnesses (JWs) refuse blood transfusions due to religious issues. This situation may impact kidney transplantation (KT) outcomes in case of hemorrhagic complications. We evaluated demographic characteristics of this population, hematologic safety, and graft outcomes.

Venom complexity of (common lancehead) siblings.

Background: Variability in snake venoms is a well-studied phenomenon. However, sex-based variation of snake venom using siblings is poorly investigated. is responsible for the majority of snakebite accidents in the Brazilian Amazon region.

Geographic variation of individual venom profile of snakes.

Background: South American rattlesnakes are represented in Brazil by a single species, , which has public health importance due to the severity of its envenomation and to its wide geographical distribution. The species is subdivided into several subspecies, but the current classification is controversial. In Brazil, the venoms of and are used for hyperimmunization of horses for antivenom production, even though the distinction of these two subspecies are mostly by their geographical distribution.

A prospective controlled randomized multicenter study to evaluate the severity of compensatory sweating after one-stage bilateral thoracic sympathectomy versus unilateral thoracic sympathectomy in the dominant side.

Objective: To evaluate the contribution that unilateral thoracic sympathectomy in dominant side or two-stage bilateral thoracic sympathectomy can have as strategies to reduce the incidence of compensatory sweating after sympathectomy for palmar hyperhidrosis.

Methods: This is a prospective, controlled, randomized multicenter trial of 200 participants with palmar hyperhidrosis, which will be randomized into two arms: (a) one-stage bilateral thoracic sympathectomy (control arm); or (b) unilateral thoracic sympathectomy in dominant side (intervention arm). At six months the participants submitted to unilateral procedure can make the contralateral surgery if they wanted it, creating a third group called two-stage bilateral sympathectomy.
