Homologous recombination deficiency (HRD) diagnostics: underlying mechanisms and new perspectives.

Homologous recombination deficiency (HRD) is considered a universal and effective sign of a tumor's sensitivity to poly(ADP-ribose) polymerase (PARP) inhibitors. HRD diagnostics have undergone several stages of transformations: from detection of point mutations in HR-related genes and large regions with loss of heterozygosity detected using single-nucleotide polymorphism arrays to whole-genome signatures of single-nucleotide variants, large genomic rearrangements (LGRs), and copy number alterations. All these methods have their own advantages and limitations.

A Novel Multiplex LAMP Assay for the Detection of Respiratory Human Adenoviruses.

Human adenoviruses (HAdVs) are common pathogens that are associated with a variety of diseases, including respiratory tract infections (RTIs). Without reliable, fast, and cost-effective detection methods for HAdVs, patients may be misdiagnosed and inappropriately treated. To address this problem, we have developed a multiplex loop-mediated isothermal amplification (LAMP) assay for the detection of the species (HAdV-B), (HAdV-C) and (HAdV-E) that cause RTIs.

Differences in Transcriptomic Profiles of Brain and Thyroid Tumors with NTRK Gene Rearrangement.

For tumors with chimeric NTRK genes, entrectinib and larotrectinib can be prescribed regardless of tumor localization. We compared changes in the transcriptional activity of genes in brain tumors (BT) and thyroid cancer (TC) with rearrangement (NTRK+) and without rearrangement (NTRK-) of the NTRK genes using The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. We revealed an increase in the transcription of the JUN gene in NTRK+ samples in comparison with NTRK- samples: by 1.

[Features of the cell composition of inflammatory infiltrate in different phases of diffuse alveolar lung damage with COVID-19].

Background: Acute respiratory distress syndrome (ARDS) with COVID-19 has a worse prognosis than ARDS with other diseases. Mortality from ARDS with COVID-19 is 26.0 - 61.

Do Sputnik V Vaccine-Induced Antibodies Protect Against Seasonal Coronaviruses? Case Study.

There are hundreds of coronaviruses, most of which circulate among animals, yet there are seven types that infect humans. Three of them can cause severe acute respiratory illness-SARS-CoV, SARS-CoV-2, and MERS-CoV. Other HCoV-229E, HCoV-OC43, HCoV-NL63, and HCoV-HKU1 usually cause only mild to moderate upper respiratory tract infections.
