Antimycobacterial activity of luteolin in resistant Mycobacterium tuberculosis isolates and cytotoxicity on L929 cells.

Mycobacterium tuberculosis (M. tuberculosis) bacteria can cause oxidative stress and the production of inflammatory cytokines, creating an environment that enhances tumour formation, progression and metastasis. Epidemiological studies have found a link between lung cancer and tuberculosis (TB), but the cellular mechanism is still unclear.

The clinical, biochemical, radiological, microbiological, and histopathological data of the patients who underwent diagnostic laparoscopy or laparotomy were analyzed retrospectively.

Development of nucleic acid based lateral flow assays for SARS-CoV-2 detection.

SARS-CoV-2 is still threat for humanity and its detection is crucial.

[Performance of MALDI-TOF MS for the identification of gram-negative bacteria grown on eosin methylene blue (EMB) agar: A simple method for improving the effectiveness of identification].

Matrix Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) is a new method that is increasingly used in microbiology laboratories due to its ability of reliable and rapid identification (ID) of bacteria and fungi. However, some problems emerge in the routine clinical diagnosis since only one gram-negative selective medium has been suggested up to date. Though EMB agar is one of the traditional gram-negative selective media, there is no data in the scientific literature, about the ID performance of MALDI TOF MS with the gram-negative bacteria grown on this medium.
