Prognostic potential of circulating cell free mitochondrial DNA levels in COVID-19 patients.

Background: In viral infections, mitochondria act as one of the main hubs of the pathogenesis. Recent findings present new insights into the potential role of circulating cell-free mitochondrial DNA (ccf-mtDNA) in COVID-19 pathogenesis by the induction of immune response and aggressive cytokine storm in SARS-CoV-2 infection.

Methods And Results: The levels of ccf-mtDNA were investigated in 102 hospitalized patients with COVID-19 using the quantitative PCR (q-PCR) method.

Association between leukocyte telomere length and COVID-19 severity.

Background: Inter-individual variations in the clinical manifestations of SARS-CoV-2 infection are among the challenging features of COVID-19. The known role of telomeres in cell proliferation and immune competency highlights their possible function in infectious diseases. Variability in telomere length is an invaluable parameter in the heterogeneity of the clinical presentation of diseases.

The study of rs324420 (C385A) polymorphism of the FAAH gene of the endocannabinoid system in patients with epilepsy and ADHD.

The endocannabinoid (eCB) system regulates many physiological functions in the central nervous system. Fatty acid amide hydrolase (FAAH) is an essential enzyme in the eCB system, degrading anandamide. Single nucleotide polymorphism (SNP) rs324420 is a common genetic polymorphism of the FAAH gene and has been associated with susceptibility to neurological conditions.

A novel mutation in the ALS2 gene in an iranian kurdish family with juvenile amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a rare disorder that affects both upper and lower motor neurons. Mutations in Alsin Rho Guanine Nucleotide Exchange Factor (ALS2) correlates with three similar but distinctive syndromes, including the juvenile form of ALS. An Iranian Kurdish family was involved in this study and all members were evaluated with relevant clinical guidelines.

Exhaled breath condensate efficacy to identify mutations in patients with lung cancer: A pilot study.

Exhaled breath condensate (EBC) is used to investigate the efficacy of EBC to detect the genetic mutations in patients with lung cancer. Samples of 5 patients and 5 healthy volunteers were collected. DNA was extracted and used for amplification of hotspot regions of and genes by using PCR.
