Previous studies have revealed that microRNA (miR)-150 can act as an oncomiR or a tumor suppressor in numerous types of hematological malignancy and solid tumor. However, the function of miR-150 in papillary thyroid carcinoma (PTC) remains elusive. The present study aimed to investigate the function of miR-150 in PTC and its underlying molecular mechanism. The expression of miR-150 was identified to be significantly downregulated, whereas that of mucin (MUC)4 was significantly upregulated in PTC tissues and cell lines compared with corresponding controls...

We diagnosed distal cholangiocarcinoma in a 76-year-old woman who was then treated by subtotal stomach-preserving pancreaticoduodenectomy. Histopathological examination revealed a well-differentiated tubular adenocarcinoma on the side of the bile duct, and a neuroendocrine carcinoma in an area outside the bile duct where the tumor had infiltrated. Immunohistochemical staining identified homology between cytokeratins and MUC, indicating a similar origin. This report discusses problems associated with diagnosis and treatment by summarizing 22 patients who underwent curative resection and subsequently had a confirmed prognosis...

Loblolly pine residues have enormous potential to be the raw material for advanced biofuel production due to extensive sources and high cellulose content. Hot water (HW) pretreatment, while being a relatively economical and clean technology for the deconstruction of lignocellulosic biomass, could also inhibit the ensuing enzymatic hydrolysis process because of the production of inhibitors. In this study, we investigated the effect of oligosaccharide fractions purified from HW pre-hydrolyzate of pinewood using centrifugal partition chromatography (CPC) on three recombinant cellulolytic enzymes (E1, CBHI and CBHII), which were expressed in the transgenic corn grain system...

South American Camelids (SAC) have unique reproductive features, one of which is that 98% of the pregnancies develop in the left uterine horn. Furthermore, early pregnancy is an uncharacterized process in these species, especially in regard to the ultrastructural, biochemical and genetic changes that the uterine epithelial surface undergoes to allow embryo implantation. The present study describes the uterine horn luminal surface and the characteristics of the mucinous glycocalyx in non-pregnant and early pregnant (15 days) female alpacas...

Dendritic cells (DCs) are major players for the induction of immune responses. Apart from plasmacytoid DCs (pDCs), human DCs can be categorized into two types of conventional DCs: CD141+ DCs (cDC1) and CD1c+ DCs (cDC2). Defining uniquely expressed surface markers on human immune cells is not only important for the identification of DC subpopulations but also a prerequisite for harnessing the DC subset-specific potential in immunomodulatory approaches, such as antibody-mediated antigen targeting. Although others identified CLEC9A as a specific endocytic receptor for CD141+ DCs, such a receptor for CD1c+ DCs has not been discovered, yet...

PURPOSE: The recurrence of T1 colorectal cancers is relatively rare, and the prognostic factors still remain obscure. This study aimed to clarify the risk factors for recurrence in patients with T1 colorectal cancers treated by endoscopic resection (ER) alone or surgical resection (SR) with lymph node dissection, respectively. METHODS: We reviewed 930 patients with resected T1 colorectal cancers (mean follow-up, 52.3 months). Patients were divided into two groups: those who underwent ER alone (298 cases), and those who underwent initial or additional SR with lymph node dissection (632 cases)...

Colorectal cancer (CRC) is the third most common malignant neoplasm worldwide. In Poland, colorectal cancer ranks second in tumor incidence regardless of sex; moreover, there has been a steady increase in the incidence of CRC. CRC results from complex interactions between inherited susceptibility, clinical conditions and environmental/lifestyle-related risk factors such as physical inactivity, smoking, alcohol consumption, high-fat/low-fiber diet, and obesity/overweight. The activation of pathways associated with insulin resistance and insulin-like growth factors (IGF) appears to be the epidemiological link between the metabolic syndrome and the development of CRC, which is of particular importance...

Asthma is characterized by inflammation and architectural changes in the lungs. A number of immune cells and mediators are recognized as initiators of asthma, although therapeutics based on these are not always effective. The multifaceted nature of this syndrome necessitate continued exploration of immunomodulators that may play a role in pathogenesis. We investigated the role of resistin-like molecule-beta (RELM-β), a gut antibacterial, in the development and pathogenesis of Aspergillus-induced allergic airways disease...

This research aimed to reveal the general morphology and topographic distribution of lingual papillae, epithelial characteristics, mucosal structure, and glands with their mucin content in the sheep tongue, with consideration of species-specific characteristics. The tongues of ten sheep were analyzed for this purpose. Filiform and fungiform papillae existed within the borders of the ventral surface of the lingual apex. The majority of the filiform papillae had multiple secondary projections. Fungiform papillae were also seen on the lingual torus among lenticular papillae, as well as 6 to 10 circumvallate papillae arranged on its caudal border...

A biocomplex of DNA nanotube-peptide, consisting of six concatenated DNA strands, three lock DNA strands and a cell-penetrating peptide was developed herein. The barrel structured DNA nanotube-peptide was successfully applied as a co-drug delivery system for targeting cancer therapy. The mucin 1 proteins (MUC-1) aptamer which is part of DNA nanotube can specially recognize MUC-1 protein on the surface of MCF-7 cells. Cyclo (Arg-Gly-Asp-D-phe-Lys) (cRGD), as a cell-penetrating peptide, facilitates recruitment and uptake of targeting drugs by binding to integrin receptors (αvβ3) of cytomembrane surface...

BACKGROUND/AIMS: Emerging studies have shown that the neutrophil-lymphocyte ratio (NLR) is a potential predictor in various tumors. Our study was conducted to assess the prognostic value of the pretreatment NLR in bladder cancer and metastatic or unresectable urothelial carcinoma (mUC or uUC) patients up to July 2017. The correlation between the pretreatment NLR and pathological characteristics was also evaluated in bladder cancer patients. METHODS: The hazard ratio (HR) and odds ratio (OR) with the 95% confidence interval (CI) were extracted or calculated from the included studies for further pooled analysis...
