1. Structural Integrity and Cellular Viability of Cryopreserved Allograft Heart Valves in Right Ventricular Outflow Tract Reconstruction: Correlation of Histopathological Changes with Donor Characteristics and Preservation Times
Abstract Introduction: Cryopreserved allograft heart valves (CAHV) show longer event-free survival compared to other types of protheses. However, all patients develop early and/or late allograft failure. Negative predictors are clinical, and there is a lack of evidence whether they correspond with the microscopic structure of CAHV. We assessed histopatholog

2. Multiple renal tumorectomy in a Von Hipple Lindau patient. Combined retro/transperitoneal approach with intracorporeal hypotermia
ABSTRACT Objective & Introduction: To show the feasibility of a combined transperitoneal (TP) and retroperitoneal (RP) laparoscopic approach in a Von Hipple-Lindau (VHL) patient with multiple kidney tumors. VHL is an autosomal dominant inherited syndrome characterized by a high incidence of benign and malignant tumors and cysts in many organs. Renal cell ca

3. Predicting urine output after kidney transplantation: development and internal validation of a nomogram for clinical use
ABSTRACT Purpose: To analyze pre-transplantation and early postoperative factors affecting post-transplantation urine output and develop a predictive nomogram. Patients and Methods: Retrospective analysis of non-preemptive first transplanted adult patients between 2001-2016. The outcomes were hourly diuresis in mL/Kg in the 1st (UO1) and 8th (UO8) postoper

4. Máquina de perfusão versus armazenamento estático na preservação renal de doadores com morte encefálica: revisão sistemática e metanálise.
RESUMO Com a utilização crescente da máquina de perfusão no transplante renal, tem sido constatado que a isquemia dinâmica correlaciona-se à melhora da preservação orgânica. Nesse contexto, realizamos uma revisão sistemática que procurou avaliar a eficácia do uso de máquina de perfusão portátil (LifePort Kidney Transporter Machine®), utilizad

5. Effect of vaporized perfluorocarbon on oxidative stress during the cold ischemia phase of lung graft preservation
RESUMO O perfluorocarbono (PFC) líquido tem sido estudado experimentalmente como uma substância adjuvante na preservação de enxertos pulmonares durante o período de isquemia fria. O objetivo deste estudo foi avaliar se o PFC vaporizado (e não instilado) também atuaria como protetor de enxertos pulmonares em diferentes tempos de isquemia fria. Realizam

6. Livedo reticularis by hypothermia during anesthesia for dental treatment in Down's syndrome patient
Resumo Justificativa: O livedo reticular representa quadro dermatológico benigno, caracterizado por áreas isquêmicas permeadas por áreas eritematocianóticas em padrão rendilhado, pode ser transitório ou permanente e frequentemente é associado à exposição corporal ao frio. O vasoespasmo arterial cutâneo promove a isquemia e a dilatação venosa d

7. Effects of remote ischemic preconditioning and topical hypothermia in renal ischemia-reperfusion injury in rats
Abstract Purpose: To evaluate whether combining hypothermia and remote ischemic preconditioning (RIPC) results in protection from ischemia-reperfusion (IR). Methods: Thirty-two Wistar rats underwent right nephrectomy and were randomly assigned to four experimental protocols on the left kidney: warm ischemia (group 1), cold ischemia (group 2), RIPC followed

8. Combined effects of melatonin and topical hypothermia on renal ischemia-reperfusion injury in rats
Abstract Purpose: To evaluate whether their combination was more effective than either alone in decreasing renal damage due to ischemia/reperfusion (I/R) injury in rats. Methods: Thirty-two Wistar rats were assigned to four groups. Following right nephrectomy, their left kidneys were subjected to warm ischemia (IR), cold ischemia (TH+IR), intraperitoneal

9. The effects of local ischemic preconditioning and topical hypothermia in renal ischemia/reperfusion injury in rats
Abstract Purpose: Topical hypothermia and local ischemic preconditioning have been shown to reduce renal ischemia-reperfusion (I/R) injury individually. We examined whether combination of both strategies lessens renal I/R injury. Methods: Post right nephrectomy, 40 male Wistar rats were randomly assigned to five experimental protocols performed in the le

10. CIRBP protects H9C2 cells against myocardial ischemia through inhibition of NF-κB pathway
Myocardial ischemia is a major cause of death and remains a disease with extremely deficient clinical therapies and a major problem worldwide. Cold inducible RNA-binding protein (CIRBP) is reported to be involved in multiple pathological processes, including myocardial ischemia. However, the molecular mechanisms of myocardial ischemia remain elusive. Here, w

11. The role of bradykinin in lung ischemia-reperfusion injury in a rat lung transplantation model
ABSTRACT PURPOSE: To investigate the role of bradykinin in a rat lung transplantation (LTx) model and preliminarily discuss the relationship between bradykinin and CD26/DPP-4. METHODS: Rats were randomly divided into four groups: Control (CON), Sham, low potassium dextranglucose (LPD), and AB192 (n=15/group). Orthotopic single LTx was performed in the LPD

12. Tetramethylpyrazine protects Schwann cells from ischemia-like injury and increases cell survival in cold ischemic rat nerves
Tetrametilpirazina (TMP), o principal componente do extrato de Ligusticum wallichi Franchat (erva chinesa), apresenta propriedades neuroprotetoras na isquemia. Nesse estudo, avaliamos seus efeitos protetores nas células de Schwann (SC), cultivando-as na presença de condições de depleção de oxigênio da glicose (OGD) e medindo a sobrevivência dos nervo
