Arthroscopic evaluation of the synovial membrane and its relationship with histological changes and biomarkers in equine joint disease. Res Vet Sci 2021; 140:212-220.

Abstract
The synovial membrane (SM) presents itself with distinctive characteristics during arthroscopic procedures in cases of osteoarthritis (OA) as well as osteochondritis dissecans (OCD) in horses. Most of the arthroscopic findings of the SM are limited to a description of a nonspecific inflammation state. In the present study, the macroscopic and histological aspects of the SM in OA and OCD horses were compared to those of healthy horses. The expression of interleukin (IL) in SM was also investigated. Besides, the concentrations of ILs and keratan sulfate (KS) in the synovial fluid (SF), and the molecular weights of the SF hyaluronic acid (HA) were also determined and correlated to the macroscopic and histological aspects of SM. This study included 10 healthy horses (control group), 12 horses with OA, and 12 with OCD. Macroscopic scores of the SM were higher in the OA group in comparison to the control and OCD groups. However, histological scores between OA and OCD were not different, and both were higher than the control group. Only in the OA group, there was a correlation between macroscopic and histological aspects of the SM, especially between volume and quantity of villi with perivascular inflammatory cells and synovial proliferation. The OA group has shown decreased expression of IL-10 in the SM, lower IL-10 and KS, and higher IL-1β and IL-6 in the SF in comparison to the control and OCD groups. There was a significant negative correlation between the macroscopic aspect of the SM and the molecular weights AH in the OA group. There was no correlation between the macroscopic aspect of the SM and all dosages in the OA and OCD group. In the OA joints, the evaluation of the shape of the SM during arthroscopy promotes a better indicator for joint inflammatory or tissue repair processes, while in the osteochondritic joints, investigation of the histological aspects are recommended to rule out an incipient OA development process. Both are helpful and should be considered to guide the postoperative treatment.

Abstract
Desbuquois dysplasia type 1 (DBQD1) is a chondrodysplasia caused by mutations in CANT1 gene encoding an ER/Golgi calcium activated nucleotidase 1 that hydrolyses UDP. Here, using Cant1 knock-in and knock-out mice recapitulating DBQD1 phenotype, we report that CANT1 plays a crucial role in cartilage proteoglycan synthesis and in endochondral ossification. Specifically, the glycosaminoglycan synthesis was decreased in chondrocytes from Cant1 knock-out mice and their hydrodynamic size was reduced, whilst the sulfation was increased and the overall proteoglycan secretion was delayed. Interestingly, knock-out chondrocytes had dilated ER cisternae suggesting delayed protein secretion and cellular stress; however, no canonical ER stress response was detected using microarray analysis, Xbp1 splicing and protein levels of BiP and ATF4. The observed proteoglycan defects caused deregulated chondrocyte proliferation and maturation in the growth plate resulting in the reduced skeletal growth. In conclusion, the pathogenic mechanism of DBQD1 comprises deregulated chondrocyte performance due to defective intracellular proteoglycan synthesis and altered proteoglycan properties in the extracellular matrix. Desbuquois dysplasia type 1 (DBQD1) is a recessive skeletal dysplasia caused by mutations in CANT1 gene, a Calcium activated nucleotidase of the ER/Golgi. The Cant1 knock-out mouse recapitulates human DBQD1. Cant1 is critical for different steps of proteoglycan biosynthesis including glycosaminoglycan chain synthesis, length and sulfation. The intracellular GAG synthesis defects cause delayed proteoglycan secretion with ER enlargement. In Cant1 knock-out chondrocytes ER enlargement is not linked to canonical ER stress. The proteoglycan defects cause deregulated chondrocyte proliferation and maturation in the growth plate resulting in reduced skeletal growth.

Abstract
Fucosylated chondroitin sulfate (FCS) and fucoidan (FUC) are two main bioactive polysaccharides in sea cucumbers. A novel method for quantitation of FCS and FUC was developed by detecting chondroitin disaccharide and fucose produced through acid hydrolysis using HPLC-MS/MS. The present method showed satisfactory performance for both saccharides. It was applied to assay sea cucumbers (Stichopus japonicus) reared in pond grow-out or bottom sowing, and the results were compared with those obtained by traditional HPLC method and 1,9-dimethylmethylene blue test, which could only provide the total sea cucumber polysaccharide (SCP) contents. No difference of total SCP content was observed between sea cucumbers reared through different ways, while a higher ratio of FCS to FUC of sea cucumbers of pond grow-out was revealed by the present method. Thus, this novel method is potential to quantify the two polysaccharides and could be a powerful tool for quality evaluation of sea cucumbers.

Abstract
A high performance size exclusion-fluorescence detection (HPSEC-FD) method combined with fluorescein isothiocyanate (FITC) prelabeling was established for the microanalysis of polysaccharide-protein complexes from longan pulp (LPP). FITC-labeled LPP (LPPF) was fractionated by gel filtration chromatography. The weight-average molecular weight and FITC substitution degree of LPPF were 39.01 kDa and 0.20%, respectively. The HPSEC-FD calibration curves linear over the range of 1-200 µg/mL in mouse plasma, spleen and lung samples with correlation coefficients greater than 0.995. The inter-day and intra-day precisions of the method were not more than 6.9%, and the relative recovery ranged from 93.7% to 106.4%. The concentration-time curve of LPPF in plasma following intravenous (i.v.) administration at 40 mg/kg body weight well fitted to a two-compartment model. LPPF rapidly eliminated from plasma according to the short half-lives (t1/2α=2.23 min, t1/2β=39.11 min) and mean retention times (MRT0-t=1.15 h, MRT0-∞=1.39 h). After administration over 5 to 360 min, the concentration of LPPF in spleen homogenate decreased from 7.41 to 3.68 µg/mL; the concentration in lung homogenate decreased from 9.08 to 3.40 µg/mL. On the other hand, the increasing concentration of LPPF fraction with low molecular weight in heart homogenate was observed.

Abstract
We have successfully synthesized a lipid containing the pyranine dye as the hydrophilic headgroup. This lipid was incorporated into liposomes with 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine as the major component. The resultant liposomes displayed differential modulations in fluorescence emission intensity in the presence of nanomolar concentrations of different glycosaminoglycans. Linear discriminant analysis of the fluorescence response data demonstrate that the liposomes are able to distinguish between different GAGs. In addition, we also demonstrate that the liposomes incorporating the pyranine lipid are able to distinguish between dilute serum from healthy individuals and serum containing elevated chondroitin sulfate (simulated serum from an Alzheimer's disease patient).

Abstract
To find whether low-frequency pulsed electromagnetic fields help repair larger cartilage defects with the assistance of tissue-engineered scaffolds, we tested their effect on the behavior of chondrocyte cells cultured on chitosan films. Primary porcine chondrocytes growing on chitosan films were exposed to low-frequency pulsed electromagnetic fields (frequency=75 Hz; impulse width=1.3 ms; strength=1.8-3 mT) 2 hours a day for 3 weeks. The cells that were not exposed to low-frequency pulsed electromagnetic fields served as controls. For 3 weeks, cell proliferation, viability, and expressions of type II collagen and glycosaminoglycan were measured weekly. Cell morphology and histological stains of glycosaminoglycan and type II collagen were performed at the end of the test. The cell proliferation and viability of the low-frequency pulsed electromagnetic fields group and the control were similar each week. By the end of the third week, cells in the low-frequency pulsed electromagnetic fields group deposited 28% more glycosaminoglycan than the control cells. The amounts of type II collagen deposited in the low-frequency pulsed electromagnetic fields group were 24% and 27% higher than those of the control group by week 2 and 3, respectively. Histological and immunohistochemical analyses confirmed the releases of glycosaminoglycan and type II collagen. Cells from both groups grew in aggregates and possessed a spherical shape after 3 weeks. These results suggest that low-frequency pulsed electromagnetic fields can enhance extracellular matrix production on chitosan substrate. Combining tissue engineering and low-frequency pulsed electromagnetic fields could further accelerate cartilage repair.

Abstract
Mucopolysaccharidoses (MPS) diagnosis is often delayed and irreversible organ damage can occur, making possible therapies less effective. This highlights the importance of early and accurate diagnosis. A high-throughput procedure for the simultaneous determination of glucosamine and galactosamine produced from urinary galactosaminoglycans and glucosaminoglycans by capillary electrophoresis (CE) and HPLC has been performed and validated in subjects affected by various MPS including their mild and severe forms, Hurler and Hurler-Scheie, Hunter, Sanfilippo, Morquio, and Maroteaux-Lamy. Contrary to other analytical approaches, the present single analytical procedure, which is able to measure total abnormal amounts of urinary GAGs, high molecular mass, and related fragments, as well as specific hexosamines belonging to a group of GAGs, would be useful for possible application in their early diagnosis. After a rapid urine pretreatment, free hexosamines are generated by acidic hydrolysis, derivatized with 2-aminobenzoic acid and separated by CE/UV in ∼10min and reverse-phase (RP)-HPLC in fluorescence in ∼21min. The total content of hexosamines was found to be indicative of abnormal urinary excretion of GAGs in patients compared to the controls, and the galactosamine/glucosamine ratio was observed to be related to specific MPS syndromes in regard to both their mild and severe forms. As a consequence, important correlations between analytical response and clinical diagnosis and the severity of the disorders were observed. Furthermore, we can assume that the severity of the syndrome may be ascribed to the quantity of total GAGs, as high-molecular-mass polymers and fragments, accumulated in cells and directly excreted in the urine. Finally, due to the high-throughput nature of this approach and to the equipment commonly available in laboratories, this method is suitable for newborn screening in preventive public health programs for early detection of MPS disorders, diagnosis, and their treatment.
