Injectable GelMA Hydrogel Microspheres with Sustained Release of Platelet-Rich Plasma for the Treatment of Thin Endometrium.

Platelet-rich plasma (PRP) intrauterine infusion has been demonstrated to be effective in treating thin endometrium and achieving pregnancy. However, the rapid release of growth factors limits its effectiveness in clinical applications, and thus, multiple intrauterine infusions are often required to achieve therapeutic efficacy. In this study, a GelMA hydrogel microsphere biomaterial is developed using droplet microfluidics to modify the delivery mode of PRP and thus prolong its duration of action.

Gamma-Glutamyltransferase Activity (GGT) Is a Long-Sought Biomarker of Redox Status in Blood Circulation: A Retrospective Clinical Study of 44 Types of Human Diseases.

Methods: The clinical GGT data from 168,858 patients with 44 diseases and 132,357 healthy control in the clinical laboratory of our hospital over the past five years were retrieved. All data were analyzed with SPSS, RStudio V.1.

Circulating Glycan Monosaccharide Composite-Based Biomarker Diagnoses Colorectal Cancer at Early Stages and Predicts Prognosis.

Introduction: Early diagnosis could lead to a cure of colorectal cancer (CRC). Since CRC is related to aging and lifestyles, we tested if the environmental information-enriched monosaccharide composite (MC) of circulating glycans could serve as an early diagnostic biomarker for CRC. Meanwhile, we evaluated its role in predicting prognosis.

Heparinoids Danaparoid and Sulodexide as clinically used drugs.

Heparin is the first glycosaminoglycan ever identified. All the heparin-like glycosaminoglycans that are also isolated from animal tissues or any polysaccharides that mimic the biological activities of heparin are called heparinoids. Heparin is the mostly sulfated glycosaminoglycan made by mast cells and an essential anticoagulant drug in modern medicine.

Coriolus versicolor polysaccharopeptide as an immunotherapeutic in China.

Coriolus versicoloris is one of the well-known traditional medicinal mushrooms used in China for over 2000 years. Polysaccharopeptide (PSP) is identified as the major bioactive component, which can be obtained from the mycelium or fermentation broth of Coriolus versicolor. The polysaccharide content in PSP is ~60% and the peptide content in PSP is ~10-30%.

Fucosylation in cancer biology and its clinical applications.

Fucosylation is the process of transferring fucose from GDP-fucose to their substrates, which includes certain proteins, N- and O-linked glycans in glycoprotein or glycolipids, by fucosyltransferases in all mammalian cells. Fucosylated glycans play vital role in selectin-mediated leukocyte extravasation, lymphocyte homing, and pathogen-host interactions, whereas fucosylated proteins are essential for signaling transduction in numerous ontogenic events. Aberrant fucosylation due to the availability of high energy donor GDP-fucose, abnormal expression of FUTs and/or α-fucosidase, and the availability of their substrates leads to different fucosylated glycan or protein structures.

CA242 as a biomarker for pancreatic cancer and other diseases.

CA242 is a sialic acid-containing carbohydrate antigen attached to core proteins/lipids detected on the cell surface or in serum. Increased serum levels of CA242 have been used clinically as diagnostic biomarkers for pancreatic, colorectal, and other cancers. Since CA242 is overexpressed in malignant tumor tissues compared to that in normal tissues, it is believed that serum CA242 is a product of cancer cells.

Retrospective analysis of glycan-related biomarkers based on clinical laboratory data in two medical centers during the past 6 years.

Most of clinically used cancer biomarkers are either specific glycan structures or glycoproteins. Although the high serum levels of the cancer biomarkers are also present in certain patients suffering noncancer diseases, systematic measurement and comparison of the serum levels of all cancer biomarkers among cancer and noncancer patients have not been reported. In this study, the serum levels of 17 glucose and glycan-related biomarkers including 10 cancer biomarkers SCCA, CA724, CA50, CA242, CA125, CA199, CA153, AFP, CEA, and PSA were retrospectively investigated based on clinical laboratory data in two medical centers during the past 6 years (2012-2018).

Optimizing microwave-assisted hydrolysis conditions for monosaccharide composition analyses of different polysaccharides.

Releasing all monosaccharides during acid hydrolysis for composition analysis of polysaccharides has been a time consuming process. In current study, an efficient (10 μL sample + 10 μL acid), sensitive, and quick monosaccharide composition analysis of polysaccharides was accomplished by using microwave-assisted HCl hydrolysis (10 min) of the polysaccharides followed by high-performance anion-exchange chromatography (HPAEC) combined with pulsed amperometric detection (PAD) analysis. Compared to the conventional hydrolysis procedure, this method is an efficient approach for monosaccharide composition analysis of acidic, basic, and neutral polysaccharides and particularly suited to polysaccharides that are difficult to hydrolyse fully such as chitosan, heparin and chondroitin sulfates.

Scallop genome reveals molecular adaptations to semi-sessile life and neurotoxins.

Bivalve molluscs are descendants of an early-Cambrian lineage superbly adapted to benthic filter feeding. Adaptations in form and behavior are well recognized, but the underlying molecular mechanisms are largely unknown. Here, we investigate the genome, various transcriptomes, and proteomes of the scallop Chlamys farreri, a semi-sessile bivalve with well-developed adductor muscle, sophisticated eyes, and remarkable neurotoxin resistance.

Scallop genome provides insights into evolution of bilaterian karyotype and development.

Reconstructing the genomes of bilaterian ancestors is central to our understanding of animal evolution, where knowledge from ancient and/or slow-evolving bilaterian lineages is critical. Here we report a high-quality, chromosome-anchored reference genome for the scallop Patinopecten yessoensis, a bivalve mollusc that has a slow-evolving genome with many ancestral features. Chromosome-based macrosynteny analysis reveals a striking correspondence between the 19 scallop chromosomes and the 17 presumed ancestral bilaterian linkage groups at a level of conservation previously unseen, suggesting that the scallop may have a karyotype close to that of the bilaterian ancestor.

Whole-Genome Restriction Mapping by "Subhaploid"-Based RAD Sequencing: An Efficient and Flexible Approach for Physical Mapping and Genome Scaffolding.

Assembly of complex genomes using short reads remains a major challenge, which usually yields highly fragmented assemblies. Generation of ultradense linkage maps is promising for anchoring such assemblies, but traditional linkage mapping methods are hindered by the infrequency and unevenness of meiotic recombination that limit attainable map resolution. Here we develop a sequencing-based "" linkage mapping approach (called RadMap), where chromosome breakage and segregation are realized by generating hundreds of "subhaploid" fosmid/bacterial-artificial-chromosome clone pools, and by restriction site-associated DNA sequencing of these clone pools to produce an ultradense whole-genome restriction map to facilitate genome scaffolding.

Genome-wide identification, characterization and expression analyses of two TNFRs in Yesso scallop (Patinopecten yessoensis) provide insight into the disparity of responses to bacterial infections and heat stress in bivalves.

Tumor necrosis factors receptors (TNFRs) comprise a superfamily of proteins characterized by a unique cysteine-rich domain (CRD) and play important roles in diverse physiological and pathological processes in the innate immune system, including inflammation, apoptosis, autoimmunity and organogenesis. Although significant effects of TNFRs on immunity have been reported in most vertebrates as well as some invertebrates, the complete TNFR superfamily has not been systematically characterized in scallops. In this study, two different types of TNFR-like genes, including PyTNFR1 and PyTNFR2 genes were identified from Yesso scallop (Patinopecten yessoensis, Jay, 1857) through whole-genome scanning.

MethylRAD: a simple and scalable method for genome-wide DNA methylation profiling using methylation-dependent restriction enzymes.

Characterization of dynamic DNA methylomes in diverse phylogenetic groups has attracted growing interest for a better understanding of the evolution of DNA methylation as well as its function and biological significance in eukaryotes. Sequencing-based methods are promising in fulfilling this task. However, none of the currently available methods offers the 'perfect solution', and they have limitations that prevent their application in the less studied phylogenetic groups.

Characterizations and expression analyses of NF-κB and Rel genes in the Yesso scallop (Patinopecten yessoensis) suggest specific response patterns against Gram-negative infection in bivalves.

Rel/NF-κB (nuclear factor kappa-light-chain-enhancer of activated B cells) genes are evolutionarily conserved and play a pivotal role in several physiological events. They have been extensively studied from various species, including both vertebrates and invertebrates. However, the Rel/NF-κB genes have not been systematically characterized in bivalves.
