Functional and phenotypic changes in natural killer cells expressing immune checkpoint receptors PD-1, CTLA-4, LAG-3, and TIGIT in non-small cell lung cancer: the comparative analysis of tumor microenvironment, peripheral venous blood, and tumor-draining veins.

Natural killer (NK) cells are a cytotoxic subset of innate lymphoid cells and have key roles in antitumoral immunity. This study evaluates the roles of immune checkpoint receptors on NK cell phenotype and functions both before and after circulation through tumor tissue. Twenty non-small cell lung cancer patients undergoing surgery and 21 healthy controls were included.

Determination of 16 European Priority Polycyclic Aromatic Hydrocarbons in Doner Kebab Varieties Cooked Under Different Heating Sources.

Doner kebab is a traditional Turkish meat product produced from lamb, beef or poultry meat seasoned with a blend of spices such as salt, black pepper, cumin, thyme and/or sauces. The aim of this study was to determine 16 EU priority polycyclic aromatic hydrocarbons (PAHs) in doner kebabs cooked under four different heating sources (electricity, open gas, wood and charcoal grilling). For this purpose, 200 meat doner and 200 chicken doner kebab samples were obtained randomly from various buffets and restaurants located in Istanbul and analyzed by means of GC-MS.

Fine tuning for totally endoscopic mitral valve surgery: ERAS applications.

Aim: One of the philosophies of minimally invasive mitral surgery is to enhance recovery after surgery (ERAS). Beyond surgical applications, ERAS applications provide a complementary approach to optimize postoperative course and discharge. In this report, we aim to present institutional protocol for ERAS and its results in patients who underwent totally endoscopic mitral valve surgery (TEMVS).

Macrophage Activation Syndrome in Coinciding Pandemics of Obesity and COVID-19: Worse than Bad.

Epigenetic changes have long-lasting impacts, which influence the epigenome and are maintained during cell division. Thus, human genome changes have required a very long timescale to become a major contributor to the current obesity pandemic. Whereas bidirectional effects of coronavirus disease 2019 (COVID-19) and obesity pandemics have given the opportunity to explore, how the viral microribonucleic acids (miRNAs) use the human's transcriptional machinery that regulate gene expression at a posttranscriptional level.
