A prospectively maintained database of 415 patients undergoing colectomy was evaluated. We performed a logistic regression analysis to identify factors associated with 1) length of stay (LOS) of 2 days or less and 2) LOS of 10 days or more. Investigated variables included demographics, American Society of Anesthesiology (ASA) score, diagnosis, operative procedure, approach and time, transfusion requirements, and occurrence of any complications. Factors associated with a LOS of two days or less included ASA [odds ratio (OR): 0...

Analysis of the cellular mechanisms of metabolic disorders, including type 2 diabetes mellitus, is complicated by the large number of reactions and interactions in metabolic networks. Metabolic control analysis with appropriate modularization is a powerful method for simplifying and analyzing these networks. To analyze control of cellular energy metabolism in adherent cell cultures of the INS-1832/13 pancreatic β-cell model we adapted our microscopy assay of absolute mitochondrial membrane potential (ΔψM) to a fluorescence microplate reader format, and applied it in conjunction with cell respirometry...

The enzyme horseradish peroxidase and the water-soluble mediator toluidine blue were covalently immobilized to 3-aminopropyl trimethoxy silane precursor through glutaraldehyde crosslinker. A rigid ceramic composite electrode was fabricated from this modified silane along with graphite powder, which resulted in an amperometric biosensor for H2O2. The electrochemical behaviour of the modified biosensor was monitored using cyclic voltammetry in the potential range of 0.2V to -0.4V vs SCE. The biosensor exhibited a stable voltammogram with cathodic peak at -0...

Using time-resolved fluorescence resonance energy transfer (FRET), we have developed and validated the first high-throughput screening (HTS) method to discover compounds that modulate an intracellular Ca(2+) channel, the ryanodine receptor (RyR), for therapeutic applications. Intracellular Ca(2+) regulation is critical for striated muscle function, and RyR is a central player. At resting [Ca(2+)], an increased propensity of channel opening due to RyR dysregulation is associated with severe cardiac and skeletal myopathies, diabetes, and neurological disorders...

Tau pathology propagates within synaptically connected neuronal circuits, but the underlying mechanisms are unclear. BIN1-amphiphysin2 is the second most prevalent genetic risk factor for late-onset Alzheimer's disease. In diseased brains, the BIN1-amphiphysin2 neuronal isoform is downregulated. Here, we show that lowering BIN1-amphiphysin2 levels in neurons promotes Tau pathology propagation whereas overexpression of neuronal BIN1-amphiphysin2 inhibits the process in two in vitro models. Increased Tau propagation is caused by increased endocytosis, given our finding that BIN1-amphiphysin2 negatively regulates endocytic flux...

BACKGROUND: One of the key factors contributing to morbidity associated with salvage radical prostatectomy is a significant vesicourethral anastomosis (VUA) disruption or postoperative tissue dehiscence in the region of the distal bladder neck that causes a large prolonged urinary leak, perineal pain, and delayed catheter removal. OBJECTIVE: To describe our surgical technique using a urinary bladder extracellular matrix (UB-ECM) scaffold incorporated into the base of the VUA and the distal bladder neck during salvage robot-assisted radical prostatectomy (sRARP) and to assess outcomes and safety...

BACKGROUND: We have reported "sandwich technique," via a right ventricular incision, to treat a post-infarction ventricular septal defect (VSD). This technique involves the placement of patches on both the left and right sides of the septum, pinching the VSD sealed with surgical adhesive between the two patches. In this study, we analyzed factors influencing 1-year mortality to determine the pitfalls in our procedure. METHODS: We evaluated 24 consecutive patients with post-infarction VSD who underwent the "sandwich technique" via a right ventricular incision...

CLS involves sudden loss of intravascular fluids into the interstitial spaces. CLS was described as a possible complication after SCT. Few studies report the incidence of CLS in pediatric populations. We aimed to assess CLS incidence, its risk factors, and impact on the survival. The clinical charts of patients <18 years of age transplanted at our institution between 2002 and 2012 were reviewed. CLS was defined by weight gain >3% in 24 hours and positive intake balance despite furosemide administration...

BACKGROUND: Patients with diabetes are considered at increased risk of delayed wound healing and infectious complications, yet the relationship between diabetes and anastomotic leak (AL) remains unclear. Given that glycosylated hemoglobin (HbA1c) is a validated indicator of the long-term glycemic state, we evaluated the relationship between preoperative HbA1c levels and AL after esophagectomy. METHODS: We assessed 300 consecutive patients who underwent esophagectomy reconstructed with cervical esophagogastric anastomosis between 2011 and 2015...

Implication Statement Infrared imager is an efficient tool for detecting gas leaks from process equipment and has been used in the Leak Detection and Repair (LDAR) programs for control of fugitive emissions. However, the information regarding which chemical compounds can be imaged and how sensitive a given infrared imager is for various compounds is limited. A theoretical method is presented in this paper that can answer these questions without conducting resource-intensive experiment. The results of this theoretical method has good agreement with experimental data...
