We identified an unusual case of human immunodeficiency virus type 1 (HIV-1) infection in a patient (GM43) who exhibited a persistently low antibody response and undetectable viral load during a 5-year follow-up period. GM43 harbored HIV-1 circulating recombinant form 01_AE with gross deletions in the nef/long terminal repeat (LTR) region. The sizes of the deletions increased progressively from 84 to >400 bp during the 5-year period. GM43 appeared to have acquired defective variants from her husband. The genetic alterations in the nef/LTR region were remarkably similar to those that have been reported in slow progressors (such as the slow progressors in the Sydney Blood Bank Cohort). The present study is the first report of slow disease progression due to gross genetic alterations in the nef/LTR region in a person infected with an HIV-1 non-subtype B strain.

Metabolism is the name given to all of the chemical reactions in the cell involving thousands of proteins, including enzymes, receptors, and transporters. Inborn errors of metabolism (IEM) are caused by defects in the production and breakdown of proteins, fats, and carbohydrates. Micro ribonucleic acids (miRNAs) are short non-coding RNA molecules, ⁓19-25 nucleotides long, hairpin-shaped, produced from DNA.

Background: Cardiac ischemia/reperfusion disrupts plasma membrane integrity and induces various types of programmed cell death. The ESCRT (endosomal sorting complex required for transport) proteins, particularly AAA-ATPase Vps4a (vacuolar protein sorting 4a), play an essential role in the surveillance of membrane integrity. However, the role of ESCRT proteins in the context of cardiac injury remains unclear.

Aim: Immune checkpoint inhibitors improved the survival of advanced non-small cell lung cancer. However, only 20% of patients respond to these treatments and the search for predictive biomarkers of response is still topical. The objective of this work is to analyze the anti-PD-1 monotherapy benefit based on genetic alterations diagnosed by next generation sequencing (NGS), in advanced non-small cell lung cancer.

Essential thrombocythemia (ET) is a type of myeloproliferative neoplasm (MPN) disorder characterized by persistent thrombocytosis and characterized by frequent association with cellular genetic alterations. The 10%-15% of ET that is not associated with genetic abnormalities is known as triple-negative essential thrombocythemia (TNET). A common complication observed in around 20% of ET patients is the development of acquired von Willebrand disease (AvWD).
