Correlation of Two-Minute and Six-Minute Walk Tests With Spirometric Indices in Patients With Severe Chronic Obstructive Pulmonary Disease at a Selected Tertiary Care Hospital in Puducherry.

Background Chronic obstructive pulmonary disease (COPD) is a progressive respiratory condition characterised by airflow limitation and reduced exercise capacity. The Six-Minute Walk Test (6MWT) and Two-Minute Walk Test (2MWT) are commonly used to assess functional exercise capacity in COPD patients. This study aims to evaluate the correlation between the distance covered in the 2MWT and 6MWT with spirometric indices (such as Forced Expiratory Volume in 1 second (FEV₁), Forced Vital Capacity (FVC), and FEV₁/FVC) in COPD patients.

Further evidence of biallelic NAV3 variants associated with recessive neurodevelopmental disorder with dysmorphism, developmental delay, intellectual disability, and behavioral abnormalities.

Neuron navigators (NAVs) are cytoskeleton-associated proteins well known for their role in axonal guidance, neuronal migration, and neurite growth necessary for neurodevelopment. Neuron navigator 3 (NAV3) is one of the three NAV proteins highly expressed in the embryonic and adult brain. However, the role of the NAV3 gene in human disease is not well-studied.

Bi-allelic variants in DAP3 result in reduced assembly of the mitoribosomal small subunit with altered apoptosis and a Perrault-syndrome-spectrum phenotype.

The mitochondrial ribosome (mitoribosome) synthesizes 13 protein subunits of the oxidative phosphorylation system encoded by the mitochondrial genome. The mitoribosome is composed of 12S rRNA, 16S rRNA, and 82 mitoribosomal proteins encoded by nuclear genes. To date, variants in 12 genes encoding mitoribosomal proteins are associated with rare monogenic disorders and frequently show combined oxidative phosphorylation deficiency.

Biallelic Variants in LRRC45 Impair Ciliogenesis and Cause a Severe Neurological Disorder.

Leucine - rich repeat containing 45 protein (LRRC45) protein localizes at the proximal end of centrioles and forms a component of the proteinaceous linker between them, with an important role in centrosome cohesion. In addition, a pool of it localizes at the distal appendages of the modified parent centriole that forms the primary cilium and it has essential functions in the establishment of the transition zone and axonemal extension during early ciliogenesis. Here, we describe three individuals from two unrelated families with severe central nervous system anomalies.

Pretargeted alpha therapy in MUC16-positive high-grade serous ovarian cancer.

Background: Peritoneal metastasis with micrometastatic cell clusters is a common feature of advanced ovarian cancer. Targeted alpha therapy (TAT) is an attractive approach for treating micrometastatic diseases as alpha particles release enormous amounts of energy within a short distance. A pretargeting approach - leveraging the inverse-electron-demand Diels-Alder reaction between tetrazines (Tz) and trans-cyclooctene (TCO) - can minimize off-target toxicity related to TAT, often associated with full-length antibodies.
