Abstract Background One hundred days after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Vietnam on 23 January, 270 cases were confirmed, with no deaths. We describe the control measures used by government and their relationship imported domestically acquired case numbers, aim of identifying associated successful SARS-CoV-2 control. Methods Clinical demographic data infected timing nature measures, including numbers tests quarantined individuals,...
Heavy metal contamination and related risks for the environment human health are matters of increasing concern.The levels 4 heavy metals (Cr, Cd, Pb, As) were evaluated in 2 water types (surface well), seafood (tiger shrimp, stuffed snail, snake-head fish, catfish), 27 vegetables (12 leafy vegetables, pea plants, tuber 7 herbs) that commonly consumed northern coastal communes located Vietnam. Atomic absorption spectrometry was employed quantification.The mean concentrations detected water,...
Chondrosarcoma has a high propensity to metastasize and responds poorly chemotherapy radiation treatment. The enzymatic activity of matrix metalloproteinases (MMPs) is very important in chondrosarcoma metastasis. Melatonin exhibits anticarcinogenic many types cancers by suppressing the expression certain MMP family members, but this not yet been clearly determined chondrosarcoma. Our study demonstrates that MMP7 plays an essential role cell proliferation, migration, anoikis resistance. We...
Hydrogen anneal is used during FinFET processing to round off the corners of silicon fins prior gate oxidation and smooth surface fin sidewalls. This procedure greatly improves leakage and, in addition, reduces width fins, resulting a lower threshold voltage improved drain-induced barrier lowering (DIBL) characteristics. Reduction current by up four orders magnitude obtained after edge rounding hydrogen annealing. In 50% decrease DIBL observed, due reduction.
Chondrosarcoma is a rare type of bone cancer that develops in cartilage cells. In recent years, the incidence chondrosarcomas has steadily increased worldwide. During advanced stages, chondrosarcoma carries significant risk metastasis and exhibits resistance to both chemotherapy radiation therapy. Hence, development potent treatments for an urgent requirement. Ugonin V flavonoid compound been extracted from plant Helminthostachys zeylanica (L.) Hook. This study examined molecular therapeutic...

Abstract The first nationwide outbreak of COVID-19 in Vietnam started late April 2021 and was caused almost exclusively by a single Delta lineage, AY.57. In early 2022, multiple Omicron variants co-circulated with quickly became dominant. co-circulation happened leading to possibility co-infection recombination events which can be revealed viral genomic data. From January October total 1028 RNA samples out 4852 positive (Ct < 30) were sequenced the long pooled amplicons method on Illumina...
Chondrosarcoma is the second most common type of bone cancer. At present, effective clinical course action surgical resection. Cisplatin chemotherapeutic medication widely used for treatment chondrosarcoma; however, its effectiveness severely hampered by drug resistance.

Our analysis revealed that glutamine metabolism highly activated in resistant but glucose not....
We report here for the first time formation of an amorphous oxide layer between polysilicon gate and hafnium (HfO/sub 2/) dielectric due to a lateral oxidation mechanism at edge. Using polySi reoxidation-free CMOS process, well behaved 80 nm MOSFETs were fabricated with no evidence oxidation.
