BACKGROUND: Methadone maintenance treatment (MMT) is underutilized in correctional settings, and those receiving MMT in the community often undergo withdrawal upon incarceration. Federal and state regulations present barriers to providing methadone in correctional facilities. For this investigation, a community provider administered methadone to inmates who had been receiving methadone prior to incarceration. We hypothesized that inmates continued on MMT would have improved behavior during incarceration and post-release...

This work evaluates the magnetically-guided delivery of DOX-loaded dendritic-Fe3O4 nanoparticles and their tumor regression efficacy in subcutaneous melanoma in C57BL/6 mice. The hematological, biochemical and histopathological parameters were minimally affected. The nanoparticles localized in lungs, liver and spleen suggesting non-specific uptake. However, in tumor-bearing mice, substantially higher localization in magnetically-targeted tumor was observed when compared to passive localization in non-targeted tumor...

Targeted temperature management (TTM, 32°C to 36°C) is one of the most successful achievements in modern resuscitation medicine. It has become standard treatment for survivors of sudden cardiac arrest to minimize secondary brain damage. TTM at 36°C is just as effective as TTM at 33°C and is actually preferred because it reduces adverse TTM-associated effects. TTM also likely has direct neuroprotective effects in ischemic brains in danger of stroke. It remains unclear, however, whether higher temperature TTM is equally effective in protecting the brain from the effects of stroke...

AIM: With increased survival after out-of-hospital cardiac arrest (OHCA), impact of the post-resuscitation course has become important. Among 30-day OHCA survivors, we investigated associations between organ support therapy in the Intensive Care Unit (ICU) and return to work. METHODS: This Danish nationwide cohort-study included 30-day-OHCA-survivors who were employed prior to arrest. We linked OHCA data to information on in-hospital care and return to work. For patients admitted to an ICU and based on renal replacement therapy (RRT), cardiovascular support and mechanical ventilation, we assessed the prognostic value of organ support therapies in multivariable Cox regression models...

Background: With advancing age there is progressive pancreatic atrophy and fibrosis, leading to tissue destruction and chronic pancreatitis that has been found to be protective against post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). However, there are no reports regarding the potential effect of the aging pancreatic changes on the incidence and severity of PEP. Therefore, the aim of the present study was to investigate the impact of senile changes in the pancreas on the incidence and severity of PEP...

BACKGROUND: Postresuscitation myocardial dysfunction (PRMD) can develop after successful resuscitation from cardiac arrest. However, echocardiographic patterns of PRMD remain unknown. This study aimed to investigate PRMD manifestations with serial echocardiography during the post-cardiac arrest period. METHODS: We enrolled non-traumatic out-of-hospital cardiac arrest patients older than 19 years who underwent successful cardiopulmonary resuscitation (CPR). We excluded patients with myocardial infarction or pre-existing cardiac disease, including heart failure or myocardial disease...

Neddylation, a post-translational modification that conjugates an ubiquitin-like protein NEDD8 to substrate proteins, is an important biochemical process that regulates protein function. The best-characterized substrates of neddylation are the cullin subunits of Cullin-RING ligases (CRLs), which, as the largest family of E3 ubiquitin ligases, control many important biological processes, including tumorigenesis, through promoting ubiquitylation and subsequent degradation of a variety of key regulatory proteins...

Cattleyak are interspecific hybrids between cattle and yak, exhibiting the same prominent adaptability as yak and much higher performances than yak. However, male infertility of cattleyak resulted from spermatogenic arrest has greatly restricted their effective utilization in yak breeding. In past decades, much work has been done to investigate the mechanisms of spermatogenic arrest, but little is known about the differences of the post-transcriptional regulators between cattleyak and yak, which may contribute to the impaired spermatogenesis...

Treatment of ischemic heart disease has evolved considerably over time, seeing a technological impetus in recent times. Prompt diagnosis and progressively earlier reperfusion of the infarct artery have become the cornerstone of the early myocardial ischemia management. However, treatment of post-infarction sequelae resulting from ischemic damage sustained within the myocardium remains a considerable challenge. In this setting, stem cell therapy has emerged as an exciting regenerative modality with a promise to arrest or even reverse the pathological myocardial remodeling...

Low survival rate occurs in patients who initially experience a spontaneous return of circulation after cardiac arrest (CA). In this study, we induced asphyxial CA in adult male Sprague-Daley rats, maintained their body temperature at 37 ± 0.5°C, and then observed the survival rate during the post-resuscitation phase. We examined neuronal damage in the hippocampus using cresyl violet (CV) and Fluore-Jade B (F-J B) staining, and pro-inflammatory response using ionized calcium-binding adapter molecule 1 (Iba-1), glial fibrillary acidic protein (GFAP), and tumor necrosis factor-alpha (TNF-α) immunohistochemistry in the hippocampus after asphyxial CA in rats under normothermia...

Cells derived from mice and other rodents exhibit profound blocks to HIV-1 virion production reflecting species-specific incompatibilities between viral Tat and Rev proteins and essential host factors Cyclin T1 (CCNT1) and Exportin-1 (XPO1, also known as CRM1), respectively. To determine if mouse cell blocks other than CCNT1 and XPO1 affect HIV's post-integration stages, we studied HIV-1NL4-3 gene expression in mouse NIH 3T3 cells modified to constitutively express HIV-1 compatible versions of CCNT1 and XPO1 (3T3...

Dinoflagellates of the genus Symbiodinium live in symbiosis with many invertebrates, including reef-building corals. Hosts maintain this symbiosis through continuous regulation of Symbiodinium cell density via expulsion and degradation (post-mitotic) and/or constraining cell growth and division through manipulation of the symbiont cell cycle (pre-mitotic). Importance of pre-mitotic regulation is unknown since little data exists on cell cycles for the immense genetic diversity of Symbiodinium. We therefore examined cell cycle progression for several distinct Symbiodinium ITS2-types (B1, C1, D1a)...

We have recently found that diabetes is associated with the inactivation of the calcium-activated potassium channels (KCa) in endothelial cells, which may contribute to endothelial dysfunction in diabetic patients at baseline. In the current study, we further investigated the effects of diabetes on coronary arteriolar responses to the small (SK) and intermediate (IK) KCa opener NS309 in diabetic and non-diabetic patients and correlated that data with the changes in the SK/IK protein expression/distribution in the setting of cardioplegic ischemia and reperfusion (CP) and cardiopulmonary bypass (CPB)...
