2. Effects of tadalafil to prevent injury on corpus cavernosum after vascular or nervous peri-prostatic bundle injury. Experimental model in rats
Abstract Purpose: To evaluate the effects of tadalafil (TD) in preventing histological alterations of the corpus cavernosum caused by isolated lesions of cavernous nerve (ILCN) and artery (ILCA) in rats. Methods: Fifty male Wistar rats were randomly assigned in five groups: G1: control; G2: bilateral ILCN; G3: bilateral ILCA; G4: ILCN+TD; G5: ILCA+TD. The

3. Effect of spironolactone on the progression of coronary calcification in peritoneal dialysis patients: a pilot study
RESUMO Introdução: Existem evidências de que a aldosterona exerça um papel na patogênese da calcificação vascular. O objetivo deste estudo foi avaliar o efeito da espironolactona, um antagonista do receptor mineralocorticoide, na progressão da calcificação coronariana (CC) de pacientes em diálise peritoneal, e identificar os fatores envolvidos ne

4. Initial inflammatory response after the pulpotomy of rat molars with MTA or ferric sulfate
Abstract Purpose To compare, both qualitatively and quantitatively, the inflammatory cells, vascular density and IL-6 immunolabeled cells present in the pulp after pulpotomy with white MTA versus 15.5% ferric sulfate (FS). Methodology Forty-eight mandibular first molars from 24 Wistar rats were divided into MTA or FS groups and subdivided according to th

5. Epiphyte-phorophyte relationships: assessing the differences between Seasonal Semideciduous and Swamp Forests in Southeastern Brazil1
RESUMO As epífitas vasculares são responsáveis por uma parcela considerável da biodiversidade tropical; no entanto, suas relações com os forófitos entre diferentes tipos de vegetação em que ocorrem ainda são pouco compreendidas. Neste trabalho, objetivamos avaliar a presença, a abundância, a distribuição vertical e a categoria ecológica (holoe

7. Microcirculation improvement after short-term infusion of vasopressin in septic shock is dependent on noradrenaline
OBJECTIVES: To assess the impact of vasopressin on the microcirculation and to develop a predictive model to estimate the probability of microcirculatory recruitment in patients with septic shock. METHODS: This prospective interventional study included patients with septic shock receiving noradrenaline for less than 48 hours. We infused vasopressin at 0.04

8. Densidad y manejo de ejes en plantas injertadas de tomate indeterminadas en invernadero
ABSTRACT Grafting in tomato is a regular production practice aimed to control vascular diseases. Even though grafted plants are more expensive, when a vigorous rootstock is used the plants can be trained using multiple leading shoots, reducing the number of plants per hectare. Seeking to reduce direct labor cost and the cost of the plants, this experiment te

9. Analysis of various potential prognostic markers and survival data in clear cell renal cell carcinoma
ABSTRACT Purpose Clear cell renal cell cancers frequently harbor Von Hippel-Lindau gene mutations, leading to stabilization of the hypoxia-inducible factors (HIFs) and their target genes. In this study, we investigated the relationship between vascular endothelial growth factor (VEGF), HIF-1α, HIF-2α, p53 positivity, microvessel density, and Ki-67 rates

10. Immunohistochemical angiogenic biomarkers in hepatocellular carcinoma and cirrhosis: correlation with pathological features
OBJECTIVE To investigate immunohistochemical markers of angiogenesis and their association with pathological prognostic features in hepatocellular carcinoma and cirrhotic liver. METHODS Vascular endothelial growth factor, CD105, and cyclooxygenase-2 were immunohistochemically detected in 52 hepatocellular carcinoma tissue samples and 48 cirrhotic liver tis

11. Estrogen deficiency in ovariectomized rats: can resistance training re-establish angiogenesis in visceral adipose tissue?
OBJECTIVE: The purpose of this study was to investigate the effects of resistance training on angiogenesis markers of visceral adipose tissue in ovariectomized rats. METHOD: Adult Sprague-Dawley female rats were divided into four groups (n=6 per group): sham-sedentary, ovariectomized sedentary, sham-resistance training and ovariectomized resistance trainin

12. Inactivated Pseudomonas aeruginosa inhibits hypoxia-induced pulmonary hypertension by preventing TGF-β1/Smad signaling
Pseudomonas aeruginosa is one of the common colonizing bacteria of the human body and is an opportunistic pathogen frequently associated with respiratory infections. Inactivated P. aeruginosa (IPA) have a variety of biological effects against inflammation and allergy. Transforming growth factor-β (TGF-β) signaling plays a critical role in the regulation of
