Genomes of a given bacterial species can show great variation in gene content and thus systematic analysis of the entire gene repertoire, termed the pan-genome, is important for understanding bacterial intra-species diversity, population genetics, and evolution. Here, we analyzed the pan-genome from 30 completely sequenced strains of the human gastric pathogen Helicobacter pylori belonging to v...

BACKGROUND The Eastern experience has reported the safety of laparoscopic assisted gastrectomy (LAG) for gastric cancer. Its use in Western countries is still debated owing to concerns about its oncologic equivalence to open gastrectomy (OG). We sought to review and compare their operative outcomes and oncologic specimen quality (number of harvested lymph nodes and surgical margins) for gastric...

GRAS transcription factors (TFs) play critical roles in plant growth and development such as gibberellin and mycorrhizal signaling. Proteins belonging to this gene family contain a typical GRAS domain in the C-terminal sequence, whereas the N-terminal region is highly variable. Although, GRAS genes have been characterized in a number of plant species, their classification is still not completel...

cycloaddition reaction between c30 and hula-i, 3-diene was studied within the snimework of am i (rhf)level. the reaction involving the double bond between two hexagons and a hexagon and a pentagon, as wellas the cycloaddition products followed by disrotatory ogs s electrocyclic ring openings were considered.thermodynamics parameters and stability energy and innsation state are evaluated in thre...

The atmosphere's carbon dioxide (CO2) content raises global temperatures. OGS, or green open space, has the power to absorb dioxide. OGS of Pinang Masak Campus, Jambi University, too this potential, although number vehicles keeps rising yearly. reduction flora at University's Campus will result in higher emissions. three-month study was carried out University. This directly measured crown and c...

Pectin, the major non-cellulosic component of primary cell wall can be degraded by polygalacturonases (PGs) and pectin methylesterases (PMEs) during pathogen attack on plants. We characterized two novel enzymes, VdPG2 VdPME1, from fungal plant Verticillium dahliae. VdPME1 was most active citrus methylesterified (55–70%) at pH 6 a temperature 40 °C, while polygalacturonic acid 5 50 °C. Using LC-...

Recent discoveries have enhanced our knowledge of the transcriptional control of oligodendrocyte (OG) development. In particular, the transcription factors (TFs) Olig2, Pax6, and Nkx2.2 have been shown to be important in the specification and/or maturation of the OG lineage. Although numerous other TFs are expressed by OGs, little is known regarding their role(s) in oligodendrogenesis. One such...

Overlapping genes (OGs) are a universal phenomenon in all kingdoms, and viruses display a high content of OGs combined with a high rate of evolution. It is believed that the mechanism of gene overlap is based on overprinting of an existing gene. OGs help virus genes compress a maximum amount of information into short sequences, conferring viral proteins with novel features and thereby increasin...

The evolution of online shopping started when big players like Amazon began selling all types merchandise. Customers understood the ease online, so trend grew even stronger. It is therefore essential to conduct a study usage and perception customers during COVID-19, especially in grocery sector. In this study, approximately 28 respondents from 50 specifically targeted groups were surveyed, data...
