Using Brassica napus roots we observed statistically significant increase in alternative respiratory pathway in response to exogenous 24-epibrassinolide (EBL) under optimal conditions and salinity. Also we observed activation of phospholipid signaling under the same conditions in response to EBL by measuring levels of lipid second messengers - diacylglycerol (DAG) and phosphatidic acid (PA). We found that brassinosteroids cause closure of stomata in isolated leaf disks while inhibitors of alternative oxidase cancelled these effects...

Translocation renal cell carcinoma and succinate dehydrogenase (SDH)-deficient renal cell carcinoma are now recognized as specific renal tumor types in the World Health Organization (WHO) classification. Both have limited immunohistochemical positivity for epithelial markers, and the spectrum of morphology continues to widen for both of these entities. We identified four renal cell carcinomas with positive TFE3 immunohistochemical staining and negative SDHB staining. The patients (2F, 2M) ranged in age from 19 to 65 years...

BACKGROUND: Treatment of nasopharyngeal carcinoma requires the application of high dosages of radiation, leading to severe long-term complications in the majority of patients. Sensitizing tumor cells to radiation could be a means to increase the therapeutic window of radiation. Nasopharyngeal carcinoma cells display alterations in autophagy and blockade of autophagy has been shown to sensitize them against chemotherapy. METHODS: We investigated the effect of chloroquine, a known inhibitor of autophagy, on sensitization against radiation-induced apoptosis in a panel of five nasopharyngeal carcinoma cell lines and a SV40-transformed nasoepithelial cell line...

BACKGROUND: Standard open surgical management of thoracolumbar infection, trauma and tumor is associated with significant morbidity. Mini-open and less morbid surgical techniques are being introduced. Our objective is to compare perioperative and immediate post-operative morbidity of open and mini-open thoracolumbar corpectomy techniques including direct hospital costs. METHODS: We retrospectively reviewed the medical records of all patients who underwent open or mini-open corpectomy along with their demographics (age, sex, body mass index (BMI), primary diagnosis), operative data (length of surgery, EBL, blood transfusion-BT), surgical level, pre- and post-operative neurologic status (using ASIA scale), immediate peri-operative complications (within 30 days post-op), overall length of stay (LOS-A), length of stay from surgery (LOS-S), and total direct hospital costs were tabulated and analyzed...

INTRODUCTION: 15%-20% of patients presenting for total hip arthroplasty (THA) have bilateral disease. While simultaneous bilateral THA is of interest to patients and surgeons, debate persists regarding its merits. The majority of previous reports on simultaneous bilateral THA involve patients in the lateral decubitus position, which require repositioning, prepping and draping, and exposure of a fresh wound to pressure and manipulation for the contralateral THA. The purpose of this study was to compare complications, component position, and financial parameters for simultaneous versus staged bilateral THAs using the direct anterior approach (DAA)...

Few-layer black phosphorus (BP) attracts much attention owing to its high mobility and thickness-tunable band gap; however, compared with the commonly studied transition metal dichalcogenides (TMDCs), BP has the unfavorable property of degrading in ambient conditions. Here, we propose an inverted dual gates structure of ultrathin BP FET to research the air adsorption on BP. In fabrication process of back-gate BP FET, BP was transferred directly onto a wafer covered with electrodes. Thus, we can exclude the BP degradation during the process of electrodes fabrication, such as electron beam lithography (EBL) and thermal evaporation process...

Renal cell carcinoma with TFEB rearrangement [t(6;11)(p21;q13)] was initially recognized to be composed of dual populations of large cells with clear cytoplasm and small cells forming rosettes around hyaline material. With increasing awareness, however, the spectrum of described morphology has been found to be more heterogeneous. We report a 54 year-old woman who underwent partial nephrectomy for a 2.4 cm renal mass, composed of fibrosis, hyalinization, calcification and ossification, and a smaller component of epithelioid cells...

Cystic nephroma in adults is an uncommon multicystic benign tumor of kidney and, over the last century, only a few small series or case reports have studied it. We analyzed 46 tumors from adults (41 female, median age: 55 y), collecting data on gross, microscopic, and immunohistochemical findings. All of the tumors were composed entirely of cysts separated by septa; the majority were surrounded by a pseudocapsule. Hypocellular fibrous and hypercellular spindle cell stroma were the most common components of the septa...

An experienced surgical team, in general, and the surgeon assistant in particular are believed to play a critical role in the operation's safety and success. We sought to explore whether the assistant's seniority influences perioperative course following robot assisted laparoscopic radical prostatectomy (RALP). We reviewed our prospective registry database of RALP cases performed by a single surgeon who during the study period was beyond his learning curve. The following parameters were documented and analyzed: patient's age, body mass index (BMI), associated comorbidities, previous abdominal surgeries, assistant's identity, total and skin-to-skin operative time (tOT, ssOT, respectively), estimated blood loss (EBL), immediate post-operative complications, length of stay (LOS), and prostate weight per final pathology report...
