TL;DR: This review focuses on the expanding role of marine collagen (MC)-based scaffolds for biomedical applications, and holds great promise as a biomaterial for developing medical products and therapeutics.
Abstract: This review focuses on the expanding role of marine collagen (MC)-based scaffolds for biomedical applications. A scaffold—a three-dimensional (3D) structure fabricated from biomaterials—is a key supporting element for cell attachment, growth, and maintenance in 3D cell culture and tissue engineering. The mechanical and biological properties of the scaffolds influence cell morphology, behavior, and function. MC, collagen derived from marine organisms, offers advantages over mammalian collagen due to its biocompatibility, biodegradability, easy extractability, water solubility, safety, low immunogenicity, and low production costs. In recent years, the use of MC as an increasingly valuable scaffold biomaterial has drawn considerable attention from biomedical researchers. The characteristics, isolation, physical, and biochemical properties of MC are discussed as an understanding of MC in optimizing the subsequent modification and the chemistries behind important tissue engineering applications. The latest technologies behind scaffold processing are assessed and the biomedical applications of MC and MC-based scaffolds, including tissue engineering and regeneration, wound dressing, drug delivery, and therapeutic approach for diseases, especially those associated with metabolic disturbances such as obesity and diabetes, are discussed. Despite all the challenges, MC holds great promise as a biomaterial for developing medical products and therapeutics.

TL;DR: Results demonstrate that leptin-ObR interactions activate Hh signaling with the latter necessary to promote trans-differentiation and have important implications for liver fibrosis and other leptin-regulated processes involving EMTs, including development, obesity, and cancer metastasis.

TL;DR: Addition of ethanol was found to eliminate the spontaneous mutation of Acetobacter sp.
Abstract: The optimum fermentation conditions for the production of cellulose by a newly isolated Acetobacter sp. A9 were determined by shaken cultures. The strain was able to produce cellulose at 25-30 degrees C with a maximum at 30 degrees C. Cellulose production occurred at pH 4.5-7.5 with a maximum at pH 6.5. The improved medium composition was 4% (w/v) glucose, 0.1% (w/v) yeast extract, 0.7% (w/v) polypeptone and 0.8% (w/v) Na(2)HPO(4).12H(2)O. Under these culture conditions, 3.8 g/l cellulose was produced after 7 days of cultivation, although this strain produced only 2.2 g/l in the standard medium. The addition of ethanol to the improved medium enhanced cellulose production: in an improved medium containing 1.4% (v/v) ethanol, cellulose production was 15.2 g/l, which was about four times higher than that without ethanol. Addition of ethanol was found to eliminate the spontaneous mutation of Acetobacter sp. A9.

TL;DR: In this article, the authors relax the assumption that the cumulative distribution function of the lead time demand is completely known and merely assume that the first two moments of F are known and finte.
Abstract: Stochastic inventory models, such as continuous review models and periodic review models, require information on the lead time demand. However, information about the form of the probability distribution of the lead time demand is often limited in practice. We relax the assumption that the cumulative distribution function, say F, of the lead time demand is completely known and merely assume that the first two moments of F are known and finte. The minmax distribution free approach for the inventory model consists of finding the most unfavourable distribution for each decision variable and then minimizing over the decision variable. We solve both the continuous review model and the periodic review model with a mixture of backorders and lost sales using the minmax distribution free approach.

TL;DR: The production of charged pions, kaons and (anti)protons has been measured at mid-rapidity ($-0.5 10$ GeV/$c$), the particle ratios are consistent with those reported for pp and Pb-Pb collisions at LHC energies as mentioned in this paper.
