BACKGROUND: Colectomy is one of the most common major abdominal procedures performed in the USA. A better understanding of risk factors and the effect of operative approach on adverse postoperative outcomes may significantly improve quality of care. METHODS: Adult patients with a primary diagnosis of colon cancer undergoing colectomy were selected from the National Surgical Quality Improvement Program 2013-2015 targeted colectomy database. Patients were stratified into five groups based on specific operative approach...

Neoadjuvant chemotherapy (NAC), the systematic chemotherapy given to patients with locally advanced and inoperable breast caner, has been proven to be of great clinical values. Many scientific reports confirmed NAC could effectively eliminate sub-clinical disseminated lesions of tumor, and improve long-term and disease-free survival rate of patients with locally advanced breast cancer (LABC); however, up to now, LABC is still a serious clinical issue given improved screening and early diagnosis. This study, with main focus on inoperable LABC, investigated the values of NAC in converting inoperable LABC into operable status and assessed the prognosis...

ABO-incompatible (ABOi) kidney transplantation has long been considered a contraindication to successful kidney transplantation. During the last 25 years, increasing organ shortage enforced the development of strategies to overcome the ABO antibody barrier. In the meantime, ABOi kidney transplantation has become a routine procedure with death-censored graft survival rates comparable to the rates in compatible transplantations. Desensitization is usually achieved by apheresis and B cell-depleting therapies that are accompanied by powerful immunosuppression...

Robert M Hoffman
We propose here a hypothesis of the cause of cancer that brings together fundamental changes in methyl-group metabolism resulting in global DNA hypomethylation which destabilizes the genome leading to aneuploid karyotypes which evolve and stabilize into autonomous cancer. Experimental support for this hypothesis is that methioine dependence is a general metabolic defect in caner. Methionine dependence is due to excess use of methionene for aberrant transmethylation reactions that apparently divert methyl groups from DNA...

OBJECTIVE: The standard transcatheter ventricular septal defects (VSD) closure procedure is established with arteriovenous (AV) loop and is called as antegrade approach. The directly retrograde transarterial VSD closure without using AV loop might be better option as shortens the procedure time and decreases radiation exposure. METHODS: Our series consist of twelve sequential adult cases with congenital VSDs (seven with perimembranous, four with muscular, one with postoperative residuel VSD)...

Scaffold proteins modulate signaling pathway activity spatially and temporally. In budding yeast, the scaffold Bem1 contributes to polarity axis establishment by regulating the GTPase Cdc42. While different models have been proposed for Bem1 function, there is little direct evidence for an underlying mechanism. Here, we find that Bem1 directly augments the Guanine Exchange Factor (GEF) activity of Cdc24. Bem1 also increases GEF phosphorylation by the p21-activated kinase (PAK), Cla4. Phosphorylation abrogates the scaffold-dependent stimulation of GEF activity, rendering Cdc24 insensitive to additional Bem1...

Human pancreatic α-amylase (HPA) is responsible for degrading starch to malto-oligosaccharides, thence to glucose, and is therefore an attractive therapeutic target for the treatment of diabetes and obesity. Here we report the discovery of a unique lariat nonapeptide, by means of the RaPID (Random non-standard Peptides Integrated Discovery) system, composed of five amino acids in a head-to-side-chain thioether macrocycle and a further four amino acids in a 310 helical C terminus. This is a potent inhibitor of HPA (Ki = 7 nM) yet exhibits selectivity for the target over other glycosidases tested...

Obestatin was shown to alleviate renal, gastrointestinal and haemorrhage-induced brain injury in rats. In order to investigate the neuroprotective effects of obestatin on seizure-induced oxidative brain injury, an epileptic seizure was induced with a single intraperitoneal (i.p.) dose of pentylenetetrazole (PTZ, 45mg/kg) in male Wistar rats. Thirty minutes before the PTZ injection, rats were treated with either saline or obestatin (1μg/kg, i.p.). Seizure was video-taped and then evaluated by using Racine's scoring (0-5)...

AIM: Peripheral artery disease (PAD) is a vascular disease affecting peripheral circulation. Recently, genome-wide association studies revealed a relationship between single nucleotide polymorphisms (SNPs) in ADAMTS7 (a disintegrin and metalloprotease with thrombospondin motif 7) and atherosclerosis. In this study, we aimed to determine ADAMTS7 expression in peripheral blood mononuclear cells (PBMCs) and the frequency of ADAMTS7 rs1994016 and rs3825807 polymorphisms in a sample of Turkish patients with PAD, and to evaluate the association of matrix metalloproteinase (MMP) levels with PAD development...

Malignant neoplasms evolve in response to changes in oncogenic signalling. Cancer cell plasticity in response to evolutionary pressures is fundamental to tumour progression and the development of therapeutic resistance. Here we determine the molecular and cellular mechanisms of cancer cell plasticity in a conditional oncogenic Kras mouse model of pancreatic ductal adenocarcinoma (PDAC), a malignancy that displays considerable phenotypic diversity and morphological heterogeneity. In this model, stochastic extinction of oncogenic Kras signalling and emergence of Kras-independent escaper populations (cells that acquire oncogenic properties) are associated with de-differentiation and aggressive biological behaviour...

Ceramic fragments from the antique city of Aizanoi, Turkey were investigated by micro Raman spectrometry in conjunction with XRPD and SEM-EDX analyses. Some basic physical characteristics of the ceramic samples were also investigated. Illite and muscovite were determined as the main clay types in the ceramic fragments. Clay used in the production of ceramic wares was found to be calcareous in most of the samples. No high temperature clay minerals were detected in the ceramics. All ceramic fragments were found to be rich in iron content...

BACKGROUND: Glioblastoma multiforme (GBM) constitutes nearly half of all malignant brain tumors and has a median survival of 15 months. The standard treatment for these lesions includes maximal resection, radiotherapy, and chemotherapy; however, individual tumors display immense variability in their response to these approaches. Genomic techniques such as whole-exome sequencing (WES) provide an opportunity to understand the molecular basis of this variability. METHODS: Here, we report WES-guided treatment of a patient with a primary GBM and two subsequent recurrences, demonstrating the dynamic nature of treatment-induced molecular changes and their implications for clinical decision-making...

Circulating tumor cells (CTCs) play an important role in estimating the presence and the metastatic relapse of tumor. Despite of their importance, isolation of viable CTCs is still struggling, since chemical or mechanical damages are unavoidable when separating less than 1000 of CTCs out of billions of other blood components. Furthermore, the current CTC isolation devices show low productivity, since they are produced after a series of complicated fabrication processes. Here, we present a low-cost and mass-producible fabric filters for the viable CTC isolation and the further molecular assay for profiling cancer-associated markers...

Immunodeficiency, centromere instability and facial anomalies (ICF) syndrome is a rare, genetically heterogeneous, autosomal recessive disorder. Patients suffer from recurrent infections caused by reduced levels or absence of serum immunoglobulins. Genetically, four subtypes of ICF syndrome have been identified to date: ICF1 (DNMT3B mutations), ICF2 (ZBTB24 mutations), ICF3 (CDCA7 mutations) and ICF4 (HELLS mutations). In this study we describe seven ICF1 patients and six novel missense mutations in DNMT3B, affecting highly conserved residues in the catalytic domain...

Atypical antipsychotic drugs induce hepatic toxicity. Thus, it is of importance to eliminate the side effects of these drugs. Herein we describe the preparation of nanoemulsions with a dietary supplement; wheat germ oil (WGO), to ameliorate the liver damage induced by clozapine and olanzapine. THLE-2 cell line was used as a model to investigate the effects of these nanoemulsions on cell viability as well as antioxidative efficiency after antipsychotic insult. In this context, a conventional cell culture method; MTT was used along with a novel cellular imaging technique called digital holography (DH) to evaluate cell viability...

Many studies have confirmed the role of postmastectomy radiotherapy (PMRT) for breast cancer patients with at least 4 lymph nodes invasion in the postoperative therapy. Recently, the number of negative lymph nodes (NLNs) has been increasingly paid attention to and recognized as a prognostic indicator in different kinds of caners. Therefore, it is very necessary to study the association between the number of NLNs and the prognosis of PMRT in breast cancer patients. In our study, we used Surveillance, Epidemiology, and End Results (SEER) population-based data and identified 16,686 breast cancer patients to explore their correlation...

BACKGROUND/AIM: Breast lesions that are not palpable on physical examination but considered suspicious for malignancy on mammography or ultrasonography should be marked before surgery. Wire-guided localization (WGL) is the most frequently used method for preoperative marking of nonpalpable breast lesions (NPBLs). An alternative is marking by a radioactive agent (radio-guided occult lesion localization; ROLL). The present study aimed to compare WGL and ROLL for preoperative marking. MATERIALS AND METHODS: The study included 25 patients marked by ROLL and 11 patients marked by WGL...
