 Cerebrovascular disease is one of the leading causes of death in the world, and about one-fourth of cerebrovascular deaths are due to ruptured cerebral aneurysms (CA). Hence it is important to find a way to reduce aneurysm formation and its subsequent morbidity and mortality. Proteolytic activity capable of lysing gelatin has been shown to be increased in aneurysm tissue and expressio...

Viruses have been hypothesized to control blooms of Aureococcus anophagefferens gen. et sp. nov. (Chrysophyceae), a marine phytoplankton that since 1985 has caused devastating summer blooms called "brown tide." By means of ultrafiltration methods, viruses specific to this alga were isolated from both the Great South Bay and Peconic Bay systems of Long Island, New York, during the summer bloom p...

Genetically-modified T cells expressing chimeric antigen receptors (CAR) exert anti-tumor effect by identifying tumor-associated antigen (TAA), independent of major histocompatibility complex. For maximal efficacy and safety of adoptively transferred cells, imaging their biodistribution is critical. This will determine if cells home to the tumor and assist in moderating cell dose. Here, T cells...

LysK, the enzyme lysing cells of Staphylococcus aureus, can be considered as perspective antimicrobial agent. Knowledge of LysK properties and behavior would allow optimizing conditions of its storage as well as formulating strategy towards its stabilization. Reaction of LysK with substrate (suspension of autoclaved Staphylococcus aureus cells) has been found to be adequately described by the t...

A bacteriophage specific for Aggregatibacter actinomycetemcomitans serotype b, able to kill the bacterium within a biofilm, was isolated. Random mutagenesis of this phage rendered a bacteriophage able to kill 99% of the bacteria within a biofilm. This is the first report of a biocontrol experiment against A. actinomycetemcomitans.

Mouse lymphoid cells, sensitized against tumor allografts, can be deprived of the immunoreactive cells by in vitro absorption with specific fibroblast monolayers. Populations of lymphocytes so depleted are less effective in retarding tumor growth in vivo and in lysing tumor cells in vitro. Moreover, the adsorbed immunoreactive cells can be recovered specifically and are subsequently efficient i...

Granular structures containing inorganic polyphosphate were found in Micrococcus lysodeikticus. These structures were isolated by fractionation of the bacterial extract obtained by lysing the organisms with lysozyme. The composition of the fraction which was enriched with these structures was found to be: protein, 24%; lipids, 30%; and polyphosphate, 27%. This fraction also contained small amou...

Abstract There is currently a high level of demand for rapid COVID-19 tests, that can detect the onset disease at point care settings. We have developed an ultra-portable, self-contained, point-of-care nucleic acid amplification test diagnosis active infection, based on principle loop mediated isothermal (LAMP). The LAMP assay 100% sensitive and specific to minimum 300 RNA copies/reaction SARS-...

conclusions this study showed that some properties of antimicrobial substances produced by the ga strain differed from other peptide antibiotics produced by the genus bacillus such as bacitracin, which increases the likelihood of its novelty. results the isolated bacterium was identified as a new strain of bacillus atrophaeus. the antimicrobial substance exhibited heat stability between 25ºc an...
