Hyaluronan synthase assembles chitin oligomers with -GlcNAc({alpha}1->)UDP at the reducing end

01.06.2015 | Paul H Weigel; Christopher M West; Peng Zhao; Lance Wells; Bruce A Baggenstoss; Jennifer L Washburn, Glycobiology , 2015

Class I hyaluronan synthases (HASs) assemble a polysaccharide containing the repeating disaccharide [GlcNAc(β1,4)GlcUA(β1,3)]n-UDP and vertebrate HASs also assemble (GlcNAc-β1,4)n homo-oligomers (chitin) in the absence of GlcUA-UDP. This multi-membrane domain CAZy GT2 family glycosyltransferase, ...


The Synthesis and Photocatalytic Properties of TiO2 Nano‐Tube Array by Starch Modified Anodic Oxidation

23.05.2015 | Fengjun Zhang, Zijian Liu, Wei Lu, Cong Lyu, Chuan Lyu, Xiansheng Wang, Photochemistry and Photobiology, 2015

Abstract In this study, the characterization and photocatalytic activity of TiO2 nanotube arrays prepared by anodization process with starch addition were investigated in detail. The results suggested that the optimum mass fraction of starch added in anodization process was 0.1 %, with which ...


Improvement in thermal stability of soybean oil by blending with camellia oil during deep fat frying

22.05.2015 | Sheng‐nan Wang, Xiao‐nan Sui, Zhong‐jiang Wang, Bao‐kun Qi, Lian‐zhou Jiang, Yang Li, Rui Wang, Xun Wei, European Journal of Lipid Science and Technology, 2015

The degradation occurring in soybean oil, camellia oil and binary blends at five ratios during deep frying of french fries at 180°C for 5 consecutive days was monitored. The decrease in polyunsaturated and increase in saturated fatty acids during the frying operation was more prominent in ...


Development of analytical methods for the determination of free and ester bound 2‐, 3‐MCPD and esterified glycidol in fishery products

22.05.2015 | Horst Karl, Sybille Merkle, Jan Kuhlmann, Jan Fritsche, European Journal of Lipid Science and Technology, 2015

In the present study existing official methods for oils were modified in order to analyse free and bound MCPD and bound glycidol in fish. Free 3‐MCPD was determined in aqueous extracts of fishery products. DGF standard methods C‐VI‐17(10) and C‐VI‐18(10) and the “3 in 1” method were modified ...


Histology of a Woolly Mammoth (Mammuthus primigenius) Preserved in Permafrost, Yamal Peninsula, Northwest Siberia

22.05.2015 | Christina Papageorgopoulou, Karl Link, Frank J. Rühli, The Anatomical Record: Advances in Integrative Anatomy and Evolutionary Biology, 2015

ABSTRACT In 2007, the baby woolly mammoth (Mammuthus primigenius) named Lyuba was found frozen in the Siberian tundra permafrost along the Yuribey River. She was proclaimed the best‐preserved mammoth discovery. As part of the endoscopic examination of Lyuba, tissue samples of hair, muscle, and ...


Application and Limitations of Endoscopy in Anthropological and Archaeological Research

22.05.2015 | Ronald G. Beckett, The Anatomical Record: Advances in Integrative Anatomy and Evolutionary Biology, 2015

ABSTRACT The use of endoscopy in anthropological and archaeological research was been well documented in the literature. This article explores the varied settings in which endoscopy is beneficial in gathering visual data for interpretation related to cultural remains and artifacts. Endoscopic ...


A Critical Look at Mummy CT Scanning

22.05.2015 | Samantha L. Cox, The Anatomical Record: Advances in Integrative Anatomy and Evolutionary Biology, 2015

ABSTRACT Computed tomography scanning of mummies has been conducted for almost 40 years, and has become an increasingly popular method of mummy study in the 21st century. However, most CT scan analyses published today still do little more than praise the technique's non‐destructive, ...


Macrophage takeover and the host–bacilli interplay during tuberculosis

22.05.2015 | Khalid Hussain Bhat; Sangita Mukhopadhyay, Future Microbiology, 2015

ABSTRACT  Macrophages are key type of antigen-presenting cells that arbitrate the first line of defense against various intracellular pathogens. Tuberculosis, both pulmonary and extrapulmonary, is an infectious disease of global concern caused by Mycobacterium tuberculosis. The bacillus is a ...


Synthetic Proteins Potently and Selectively Bind the Oncoprotein Gankyrin, Modulate Its Interaction with S6 ATPase, and Suppress Gankyrin/MDM2-Dependent Ubiquitination of p53

22.05.2015 | Alex M. Chapman; Brian R. McNaughton, ACS Chemical Biology, 2015

Overexpression of the ankyrin repeat oncoprotein gankyrin is directly linked to the onset, proliferation, and/or metastasis of many cancers. The role of gankyrin in multiple disease-relevant biochemical processes is profound. In addition to other cellular processes, gankyrin overexpression leads ...


In vitro exposure: Linear and non‐linear thermodynamic events in Petri dishes

20.05.2015 | Alessandra Paffi, Micaela Liberti, Francesca Apollonio, Asher Sheppard, Quirino Balzano, Bioelectromagnetics, 2015

We conducted an electromagnetic‐thermal analysis of Petri dishes filled with different medium volumes under different radio frequency exposure conditions with the aim of identifying linear and non‐linear parameters that might explain contradictory results of many in vitro bioelectromagnetic ...
