Heparan sulfate (HS) is a linear polysaccharide with high structural and functional diversity. Detection and localization of HS in tissues can be performed using single chain variable fragment (scFv) antibodies. Although several anti-HS antibodies recognizing different sulfation motifs have been identified, little is known about their interaction with HS.

Salinization is one of the leading causes of arable land shrinkage and rice yield decline, recently. Therefore, developing and utilizing salt-tolerant rice varieties have been seen as a crucial and urgent strategy to reduce the effects of saline intrusion and protect food security worldwide. In the current study, the CRISPR/Cas9 system was utilized to induce targeted mutations in the coding sequence of the OsDSG1, a gene involved in the ubiquitination pathway and the regulation of biochemical reactions in rice.

Disease-resistant varieties, which are generated by reducing the impact of susceptibility genes through mutation in host plants, would be an effective approach to protect crops from this disease. The Mildew Locus O (MLO) genes are well-known susceptibility genes for powdery mildew in plant.

Tomato (Solanum lycopersicum) is one of the most popular and consumed vegetable crops in the world. Among important traits for tomato improvement such as yield, biotic and abiotic resistances, appearance, post-harvest shelf life and fruit quality, the last one seems to face more challenges because of its genetic and biochemical complexities.

Here, the relationship between the clinical spectrum and the HLA allele profiles in patients with CBZ-induced hypersensitivity reactions was investigated using next-generation sequence (NGS) data obtained from 65 Vietnamese patients with epilepsy, including 33 with CBZ-tolerance and 32 patients with CBZ-hypersensitivity, in which only 8 with severe cutaneous adverse drug reactions and 24 were mild-hypersensitive patients. Three loci of HLA class I (HLA-A, -B, and -C) and two loci of HLA class II (HLA-DQA1 and -DRB1) were included in our analysis.

The gRNAs for targeted mutations of an exogenous gene and multiple endogenous genes were constructed and transferred into a stably-overexpressed-Cas9 soybean line using -mediated hairy root induction system. The targeted mutations were identified and characterized by the poly-acrylamide gel electrophoresis (PAGE) heteroduplex method and by sequencing.
View Article and Find Full Text PDFTobacco is an important commercial crop and a rich source of alkaloids for pharmaceutical and agricultural applications. However, its yield can be reduced by up to 70% due to virus infections, especially by a potyvirus Potato virus Y (PVY). The replication of PVY relies on host factors, and eukaryotic translation initiation factor 4Es (eIF4Es) have already been identified as recessive resistance genes against potyviruses in many plant species.

Extracellular vesicle (EV) cargos are specific to the source cells, hence they have the potential of being a source of cancer-specific proteins. Methods: The proteins differently expressed in cancer were determined and derived from EVs isolated from the plasma of NSCLC patients at the National Lung Hospital.

Constitutive expression of GA20ox has successfully improved plant growth and biomass in several plant species. However, the constitutive expression of this gene causes side-effects, such as reduced leaf size and stem diameter, etc.

Hence, a major goal is to reduce RFO levels to improve the nutritional quality of soybean. In this study, we utilized a dual gRNAs CRISPR/Cas9 system to induce knockouts in two soybean galactinol synthase (GOLS) genes, and its homeolog .

Heparin-binding proteins (HBPs) play a central role in health and diseases. Therefore, we used heparin affinity proteomics to identify extracellular HBPs in pancreas and plasma of normal mice and in a caerulein mouse model of AP.
View Article and Find Full Text PDFOctreotide is a somatostatin analog known for its role in the treatment of acute variceal bleeding, enterocutaneous fistula and carcinoid syndrome. The reduction of portal pressure from splanchnic vasoconstriction has been attributed to the inhibition of nitric oxide synthesis, guanylate cyclase and release of glucagon. Octreotide has many therapeutic applications as a result of the ubiquitous nature of somatostatin receptors throughout the body.

In particular, the gelatinases MMP-2 and -9 have been revealed to facilitate tumor growth and invasion in patients with colorectal cancer (CRC). However, it is not known whether the gelatinase activity of MMP-2 and -9 is also elevated in Vietnamese patients with CRC.

The number of episodes of diabetic ketoacidosis (DKA) is a significant outcome measure for diabetes care. We ascertained patterns of admission due to DKA over 15 yr to determine whether this indicator of diabetes care had improved in parallel with clinical practices. Between 1 January 1985 and 31 December 1999, 630 admissions were reviewed.
