OBJECTIVES: We designed a pilot study to evaluate safety and feasibility of an inexpensive and simple approach to intracoronary hemodilution during primary angioplasty (PPCI) to reduce reperfusion injury. INTRODUCTION: Early revascularization in acute myocardial infarction decreases infarct size and improves outcomes. However, abrupt restoration of coronary flow results in myocardial reperfusion injury and increased final infarct size. Dilution of coronary blood during revascularization may help reduce this damage...

A 73-year-old man with lower abdominal pain was diagnosed at our hospital with sigmoid colon cancer. He had previously undergone radical cystectomy with Indiana pouch construction and gastrectomy to treat bladder cancer and gastric cancer, respectively. We performed a laparoscopic Hartmann's operation with Japanese D3 lymph node dissection. We observed severe adhesion in the abdominal cavity; adhesions between the urostomy and sigmoid colon were particularly severe. The tumor had invaded to the distal rectum, which had adhered to the pubic bone and the previously reconstructed urinary pouch...

PURPOSE: Genome-wide analyses revealed basal and luminal subtypes of urothelial carcinomas of the bladder. It is unknown if this subtyping can also be applied to upper tract urothelial carcinomas. MATERIALS AND METHODS: Tumor samples from 222 patients with upper tract urothelial carcinomas who were treated with radical nephroureterectomy were analyzed for the expression of seven basal/luminal immunohistochemical markers (CK5, EGFR, CD44, CK20, p63, GATA3, FOXA1)...

BACKGROUND AND PURPOSE: Identification of salvageable penumbra tissue by dynamic susceptibility contrast magnetic resonance imaging is a valuable tool for acute stroke patient stratification for treatment. However, prior studies have not attempted to combine the different perfusion maps into a predictive model. In this study, we established a multiparametric perfusion imaging model and cross-validated it using positron emission tomography perfusion for detection of penumbral flow. METHODS: In a retrospective analysis of 17 subacute stroke patients with consecutive magnetic resonance imaging and H2O15 positron emission tomography scans, perfusion maps of cerebral blood flow, cerebral blood volume, mean transit time, time-to-maximum, and time-to-peak were constructed and combined using a generalized linear model (GLM)...

BACKGROUND: Diabetes mellitus is a major risk factor for prolonged hospital stays, renal failure, and mortality in patients having coronary artery bypass grafting (CABG). Complications pose a serious threat to patients and prolong intensive care and hospital stays. Low glomerular filtration rate (GFR) due to existing renal impairment or volume depletion may exacerbate acute renal impairment/failure in these patients. Preoperative volume replacement therapy (VRT) is reported to increase the GFR and we hypothesize that VRT will reduce renal impairment and related complications in diabetic patients...

Structural and dynamic investigations of unfolded proteins are important for understanding protein-folding mechanisms as well as the interactions of unfolded polypeptide chains with other cell components. In the case of outer-membrane proteins (OMPs), unfolded-state properties are of particular physiological relevance, because these proteins remain unfolded for extended periods of time during their biogenesis and rely on interactions with binding partners to support proper folding. Using a combination of ensemble and single-molecule spectroscopy, we have scrutinized the unfolded state of outer-membrane phospholipase A (OmpLA) to provide a detailed view of its structural dynamics on timescales from nanoseconds to milliseconds...

INTRODUCTION: Intestinal ischemia-reperfusion (I/R) injury may cause cell and tissue damage, reaching also other organs such as the liver. Because of the involvement of free radicals in I/R injury, treatment options with antioxidants have been studied and tested. OBJECTIVE: To evaluate the effect of glutamine (Gln) in the liver of animals with intestinal I/R injury. METHODS: We used 20 male Wistar rats divided into four groups: sham-operated (SO); glutamine + sham-operated (G+SO); intestinal ischemia-reperfusion (I/R); glutamine + intestinal ischemia-reperfusion (G+I/R)...

BACKGROUND: Children's dietary-related diseases and their associated costs have expanded dramatically in many countries, making children's food choice a policy issue of increasing relevance. As children spend a considerable amount of money on energy-dense, nutrient-poor (EDNP) products, a better understanding of the main drivers of children's independent food purchase decisions is crucial to move this behavior toward healthier options. OBJECTIVE: The objective of the study is to investigate the role of branding and price in motivating children to choose healthier snack options...

The Hartmann procedure - primarily - was introduced for the treatment of cancerous diseases of sigmoid colon and rectum. In the last few years it was performed in cases with complicated inflammation of the left colon, colon cancers with bowel obstruction or perforation, or in the case of insufficiency of the anastomoses, or in urgent operations after traumatics bowel injuries, when making the anastomosis is at very high risk. Later on the restoration of the continuity of the GI tract can be done traditionally (by laparotomy) or laparoscopically...

Antimicrobial resistance in livestock is a matter of general concern. To develop hygiene measures and methods for resistance prevention and control, epidemiological studies on a population level are needed to detect factors associated with antimicrobial resistance in livestock holdings. In general, regression models are used to describe these relationships between environmental factors and resistance outcome. Besides the study design, the correlation structures of the different outcomes of antibiotic resistance and structural zero measurements on the resistance outcome as well as on the exposure side are challenges for the epidemiological model building process...

Germ cell development involves major reprogramming of the epigenome to prime the zygote for totipotency. Histone 3 lysine 4 (H3K4) methylations are universal epigenetic marks mediated in mammals by six H3K4 methyltransferases related to fly Trithorax, including two yeast Set1 orthologs: Setd1a and Setd1b. Whereas Setd1a plays no role in oogenesis, we report that Setd1b deficiency causes female sterility. Oocyte specific Gdf9iCre conditional knockout (Setd1b(Gdf9) cKO) ovaries develop through all stages however follicular loss accumulated with age and unfertilized metaphase II (MII) oocytes exhibited irregularities of the zona pellucida and meiotic spindle...

The aim of this study was to determine whether dynamic accommodation responds to isolated blur cues without feedback, and without changes in the distance of the object. Nine healthy subjects aged 21 to 40 years were recruited. Four different aberration patterns were used as stimuli to induce blur: (1) the eye's natural, uncorrected, optical aberrations, (2) all aberrations corrected, (3) spherical aberration only, and (4) astigmatism only. The stimulus was a video animation based on computer-generated images of a monochromatic Maltese cross...

Almost all mammals use their mystacial vibrissae (whiskers) as important tactile sensors. There are no sensors along the length of a whisker: all sensing is performed by mechanoreceptors at the whisker base. To use artificial whiskers as a sensing tool in robotics, it is essential to be able to determine the three-dimensional (3D) location at which a whisker has made contact with an object. With the assumption of quasistatic, frictionless, single-point contact, previous work demonstrated that the 3D contact point can be uniquely determined if all six components of force and moment are measured at the whisker base, but these measurements require a six-axis load cell...

Immunotherapy with programmed cell death protein-1 (PD-1) antibodies (pembrolizumab and nivolumab) has been approved in Europe for the first-line treatment of several tumour entities, e. g. malignant melanoma. Following the resounding therapeutic success of these antibodies in different types of tumours, their potential in urological tumours has been investigated in several studies. The approval of the PD-1 antibody nivolumab for the treatment of metastasised renal cell carcinoma has set a new milestone in urooncology...

Phosphaturic mesenchymal tumor (PMT) is a rare neoplasm of uncertain histogenesis that has been linked to tumor-induced osteomalacia (TIO) since 1959. The neoplastic cells produce increased amount of FGF23 which results in TIO via uncontrolled renal loss of phosphate (phosphaturia), and consequently diminished bone mineralization. To date, ∼300 cases have been reported. Although there is increasing evidence that PMT can be diagnosed by reproducible histopathologic features, firm diagnosis has been often restricted to cases associated with TIO and, hence, diagnosis of "nonphosphaturic variants" remained challenging...

Patients suffering from Parkinson's disease (PD) often show impairments in executive function (EF) like decision-making and action control. The right dorsolateral prefrontal cortex (dlPFC) has been strongly implicated in EF in healthy subjects and has repeatedly been reported to show alterations related to EF impairment in PD. Recently, two key regions for cognitive action control have been identified within the right dlPFC by co-activation based parcellation. While the posterior region is engaged in rather basal EF like stimulus integration and working memory, the anterior region has a more abstract, supervisory function...
