Glycosaminoglycans (GAGs), as animal polysaccharides, are linked to proteins to form various types of proteoglycans. Bacterial GAG lyases are not only essential enzymes that spoilage bacteria use for the degradation of GAGs, but also valuable tools for investigating the biological function and potential therapeutic applications of GAGs. The ongoing discovery and characterization of novel GAG lyases has identified an increasing number of lyases suitable for functional studies and other applications involving GAGs, which include oligosaccharide sequencing, detection and removal of specific glycan chains, clinical drug development and the design of novel biomaterials and sensors, some of which have not yet been comprehensively summarized.

Introduction: The mortality rate for liver cancer is extremely high but clinical treatments have not made much progress, so it is necessary to develop anticancer agents with lower toxicities and more effective liver-targeting drug delivery systems (LTDDSs). At present, LTDDSs mediated by the asialoglycoprotein receptor (ASGPR) show excellent effects at improving the liver-targeting and antitumor effects of drugs. However, the galactosyl ligands are typically prepared by chemical synthesis and have some shortcomings.

Through morphological and molecular studies, the natural life cycle of Dollfus, 1960 (Cestoda: Taeniidae) from Argentine Patagonia is elucidated, involving subterranean rodents (Ctenomyidae) as intermediate hosts, and the Andean fox (Canidae) as definitive host. Metacestodes (mono- and polycephalic fimbriocerci) were found mainly in the peritoneal cavity of , and the strobilate adult in the intestine of . Correspondence between metacestodes and strobilate adults was based primarily on number, size and shape of rostellar hooks: 45-53 hooks alternated in two rows, small hooks 88-180 μm long and large hooks 230-280 μm long, with the characteristic shape described in the two main description of the species, both that of the metacestode (original description) and that of the strobilate adult (obtained experimentally).

Gold-silver synergism has been well documented in many scientific works dealing with luminescent nanostructures that are exploitable in biomedical and environmental application. Frequently, the ratio of Au : Ag in synthetic mixtures was varied to influence the extent of Au-Ag synergism of the resulting luminescent gold-silver nanoclusters (GSNCs). However, in our approach, a new step, maturing under differing conditions using the same Au : Ag ratio (5 : 1), has been investigated systematically for the very first time.

Objective: The objective is to evaluate the effectiveness of two different penetration depths of micro-osteoperforations (MOPs) on the rate of orthodontic tooth movement over 60 days. In addition, the amount of pain and discomfort caused by the MOP was evaluated.
Materials And Methods: A total of 22 patients (18-30 years) who need fixed orthodontic treatment were recruited and randomly assigned into two groups.
