Most of the research on DBC1 has focused on metabolism and epigenetics because it is a crucial endogenic inhibitor of deacetylase Sirtuin1 (SIRT1). In this review, we have discussed and summarized the new advances in DBC1 research, mostly focusing on its structure, regulatory function, and significance in cancer and autoimmune diseases. ©2020 Society for Leukocyte Biology.Sinonasal tumors consist of a group of rare heterogeneous malignancies, accounting for 3-5% of all head and neck cancers. While squamous cell carcinomas make up a significant portion of cancers arising in the sinonasal tract there are a variety of aggressive tumor types that can present with a poorly differentiated morphology and continue to pose diagnostic challenges. Accurate classification of these unique malignancies has treatment implications for patients. Recent discoveries have allowed more detailed molecular characterization of subsets of these tumor types, and may lead to individualized treatments. INI-1 (SMARCB1) deficient sinonasal carcinoma is a recently identified subtype of sinonasal malignancy, which is characterized by deletion of the INI-1 tumor suppressor gene. Loss of INI-1 expression has emerged as an important diagnostic feature in several human malignancies including a subset of sinonasal carcinomas. In this article, we present a case of INI-1 (SMARCB1) deficient sinonasal carcinoma, provide an overview of recent advances in histological and molecular classification of sinonasal malignancies, and discuss challenges of caring for patients with these rare malignancies, as well as potential treatment implications. © AlphaMed Press 2020.BACKGROUND Chronic constipation is a gastrointestinal functional disorder which affects patient quality of life. Therefore, many studies were oriented to search herbal laxative agents. In this study, we investigated the effect of Globularia alypum L. leaves aqueous extract (GAAE) against loperamide (LOP)-produced constipation. METHODS Animals were given LOP (3 mg/kg, b.w., i.p.) and GAAE (100, 200, and 400 mg/kg, b.w., p.o.) or yohimbine (2 mg/kg, b.w., i.p.), simultaneously, for 1 week. Gastric-emptying test and intestinal transit were determined. Colon histology was examined, and oxidative status was evaluated using biochemical-colorimetric methods. KEY RESULTS GAAE ameliorates significantly gastric emptying (64% to 76.5%) and intestinal transit (66.65% to 84.73%). LOP negatively influenced defecation parameters and generated a stress situation. GAAE administration in contrast ameliorated those parameters and re-established oxidative balance. CONCLUSION GAAE showed a modest action against oxidative stress and decreased LOP effect and thereby can be considered a pharmacological agent in constipation. © 2020 John Wiley & Sons Ltd.Raman optical activity (ROA) is pursued as a promising method for structural analyses of sugars in aqueous solutions. In the present study, experimental Raman and ROA spectra of glucose and sorbose obtained in an extended range (50 - 4000 cm -1 ) are interpreted using molecular dynamics and density functional theory, with the emphasis on CH stretching modes. A reasonable theoretical basis for spectral interpretation was obtained already at the harmonic level. Anharmonic corrections led to minor shifts of band positions (up to 25 cm -1 ) below 2000 cm -1 , while the CH stretching bands shifted more, by ~180 cm -1 . However, the anharmonicities could be included on a relatively low approximation level only, and did not always improve the harmonic band shapes. The dependence on the structure and conformation shows that the CH stretching ROA spectral pattern is a sensitive marker useful in saccharide structure studies. © 2020 WILEY-VCH Verlag GmbH & Co.

Unfortunately, the humoral concentrations of most biotargets generally vary within rather limited scopes between normal and pathological states, while most literature-reported biosensors can detect large spans of targets concentrations, but are less sensitive to small concentration changes, which consequently make them mostly unsatisfactory or even unreliable in distinguishing positives from negatives. Herein, a novel strategy of precisely quantifying the small concentration changes of a certain biotarget by editing the dynamic ranges and sensitivities of a lanthanide-based metal-organic framework (Eu-ZnMOF) biosensor is reported. Selleck Bufalin By elaborately tailoring the biosensor's structure and surface areas, the tunable Eu-ZnMOF is developed with remarkably enhanced response slope within the "optimized useful detection window," enabling it to serve as a powerful signal amplifier (87.2-fold increase) for discriminating the small concentration variation of urinary vanillylmandelic acid (an early pathological signature of pheochromocytoma) within only three times between healthy and diseased subjects. This study provides a facile approach to edit the biosensors' performances through structure engineering, and exhibits promising perspectives for future clinical application in the non-invasive and accurate diagnosis of severe diseases. © 2020 WILEY-VCH Verlag GmbH & Co.

In this paper new description of this clathrate structure is suggested. Main structural unit in this description is '4-column', the set of four nearest columns of 14-hedral T-cages together with its internal filling by the pillar of mutually orthogonal pairs of T-cages. Comparison based on this new description of clathrate III and clathrate I (CS-I) shows that 4-column is maximal common structural element of these two structures. On this ground it is argued that clathrate III can be considered as a modification of the clathrate I, formed as a result of multiple interruption of clathrate I crystal growth. At the same time, it is shown that due to crucial differences between these two structures there does not exist structural or reconstructive phase transition between them. Integral character of 4-columns as the structural units of clathrate III is confirmed by the analysis of the most studied case of ionic hydrates of tetraalkylammonium salts in which guest molecules occupy simultaneously T-cages in outer columns and inner T-cages.
