Bothrops atrox envenomations in the Brazilian Amazon are responsible for a number of local and systemic effects. Among these, stroke presents the worst prognosis for the patient since it may evolve into disabilities and/or premature death. This complication is caused by coagulation disorders and generates hemorrhagic and thrombotic conditions.

Local effects represent a relevant clinical issue, in which inflammatory signs and symptoms in the bite site represent a potential risk for short and long-term disabilities. Among local complications, secondary infections (SIs) are a common clinical finding during SBE and are described by the appearance of signs such as abscess, cellulitis or necrotizing fasciitis in the affected site.

However, it is associated with aneurysm enlargement and may require secondary interventions. Its role has been widely investigated, but a definitive consensus about its management has still not been obtained.

Objectives: To assess the safety and efficacy of prostatic artery embolization (PAE) to reduce prostate volume (PV) and facilitate intermittent catheterization (IC) in individuals with concurrent benign prostatic hyperplasia (BPH) and spinal cord injury (SCI).
Setting: Italian tertiary referral center for people with SCI.

Introduction: Snakebites in the Brazilian Amazon are caused mostly by snakes from the Bothrops genus and envenomated patients may suffer from tissue complications.
Methods: This study aimed to identify risk factors for severe tissue complications (STC) in patients with Bothrops snakebite in the Amazonas state, Brazil.
Results: Snakebites that were classified as severe and affected female patients with comorbidities presented greater risks of developing STCs.
Background: To assess imaging findings, describe endovascular technical aspects and analyzed procedural outcomes in a population of patients underwent limb arteriovenous malformation (LAVMs).
Methods: From January 2015 to December 2018, all consecutive patients underwent an endovascular procedure for ICD-9-CM codex for arteriovenous malformation problems were retrospective reviewed. Among these, patients with LAVMs were selected.
Purpose: Patient-derived xenograft (PDX) models accurately recapitulate the tumor of origin in terms of histopathology, genomic landscape, and therapeutic response, but some limitations due to costs associated with their maintenance and restricted amenability for large-scale screenings still exist. To overcome these issues, we established a platform of 2D cell lines (xeno-cell lines, XL), derived from PDXs of colorectal cancer with matched patient germline gDNA available.
Experimental Design: Whole-exome and transcriptome sequencing analyses were performed.

: Hemoperitoneum can be a life-threating condition in cirrhotic patients who have a limited compensatory reserve during hemorrhagic shock. We aim to review the literature on the different etiologies associated with non-traumatic hemoperitoneum (NTH), summarizing the most relevant conditions associated with spontaneous and iatrogenic peritoneal and retroperitoneal bleeding that may occur in cirrhotic patients and to illustrate the most relevant diagnostic strategies and optimal management. : This review encompasses the current literature in hemoperitoneum in cirrhotic patients in the absence of abdominal trauma.

Materials And Methods: We retrospectively evaluated 23 patients with a mean age of 39 years (range: 17-74 years) who underwent TEVAR for BTTAI between October 2000 and November 2014. All of the patients underwent computed tomography angiography (CTA) before hospital discharge as a baseline imaging for the subsequent follow-up examinations.
Objective: The present study evaluated the nociceptive response induced by dentin hypersensitivity after dental erosion in rats that were exhibited to unpredictable chronic mild stress (UCMS)-induced depressive-like behavior.
Design: Adult male rats were subjected to UCMS (depression [D] group) or not (no depression [ND] group) for 30days and received either acidic solution to induce dental erosion (E) or water (W), thus forming the WND, END, WD, and ED groups. After the end of treatment, depressive-like parameters (i.
Purpose: To prospectively assess discontinuation of indwelling bladder catheterization (IBC) and relief of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) following prostate artery embolization (PAE) in poor surgical candidates.
Methods: Patients ineligible for surgical intervention were offered PAE after at least 1 month of IBC for management of urinary retention secondary to BPH; exclusion criteria for PAE included eligibility for surgery, active bladder cancer or known prostate cancer. Embolization technical and clinical success were defined as bilateral prostate embolization and removal of IBC, respectively.
Gomesin is an 18-residue cysteine-rich antimicrobial peptide produced by hemocytes of the spider Acanthoscurria gomesiana. In the present study, the antifungal properties of gomesin against Cryptococcus neoformans, the etiologic agent of cryptococcosis, were evaluated. Gomesin bound to the cell surface of cryptococci, which resulted in cell death associated with membrane permeabilization.

GXM receptors have been characterized in phagocytes and endothelial cells, but epithelial molecules recognizing the polysaccharide remain unknown. In the current study, we demonstrate that GXM binds to the CD14 receptor in human type II alveolar epithelial cells, resulting in the production of the proinflammatory chemokine interleukin-8.
