Objective: To compare the behavioral improvement to find the best transplantation approach for treating brain injury through transplanting amniotic-derived mesenchymal stem cells into brain injured rats in different ways.
Methods: Eighty brain injured Wista rats were randomly divided into a control group with brain injury alone (n=20) and a treatment group(n=60) which were further evenly divided into Group A (transplanted through the vena caudalis), Group B (transplanted through the ventriculus cerebri lateralis), and Group C (transplanted through the injured brain area). Each group was transplanted with amniotic-derived esenchymal stem cells, and their therapeutic efficacy would be evaluated through the neurological severity score (NSS).
Results: Compared with other groups, the behaviors of Group C had markedly improved. There was statistically significant difference in the 2 groups (P<0.05). Compared with the control group, the behaviors of Group A and Group B had marked improvement. There was statistically significant difference in the 3 groups (P<0.05). However, there was no significant difference between Group A and the control group (P>0.05).
Conclusion: Transplanting the amniotic-derived mesenchymal stem cells into the injured brain area may be effective for brain injury in rats.

Currently, the barrier to successful lung transplantation is ischemia and reperfusion injury, which can lead to the development of bronchiolitis obliterans. Paclitaxel and methotrexate are drugs known to inhibit cell proliferation and have anti-inflammatory effects, and the association of these drugs with cholesterol-rich nanoparticles has been shown to be beneficial in the treatment of other transplanted organs. Thirty-three male Sprague Dawley rats were divided into 3 groups: Basal group, no intervention; Control group, received only nanoparticles; Drug group, paclitaxel and methotrexate treatment.

The 2015-2016 Zika virus (ZIKV) outbreak in the Americas revealed the ability of ZIKV from the Asian lineage to cause birth defects, generically called congenital Zika syndrome (CZS). Notwithstanding the long circulation history of Asian ZIKV, no ZIKV-associated CZS cases were reported prior to the outbreaks in French Polynesia (2013) and Brazil (2015). Whether the sudden emergence of CZS resulted from an evolutionary event of Asian ZIKV has remained unclear.

Introduction: End-stage kidney disease patients face a critical decision regarding kidney replacement therapy options, which include kidney transplantation, hemodialysis, or peritoneal dialysis (PD). This study aims to evaluate the impact of nurse-led education (NE) alone vs. NE combined with peer support on the patients' decision over PD treatment in chronic kidney disease patients.

Background: Enhanced recovery after surgery (ERAS) protocols have gained widespread acceptance as a means to enhance surgical outcomes. However, the intricate care required for kidney transplant recipients has not yet led to the establishment of a universally recognized and dependable ERAS protocol for kidney transplantation.
Objective: We devised a customized ERAS protocol to determine its effectiveness in improving surgical and postoperative outcomes among kidney transplant recipients.
