Towards assembling functional cyanobacterial β-carboxysomes in Oryza sativa chloroplasts.

The major limiting factor of photosynthesis in C3 plants is the enzyme, rubisco which inadequately distinguishes between carbon dioxide and oxygen. To overcome catalytic deficiencies of Rubisco, cyanobacteria utilize advanced protein microcompartments, called the carboxysomes which envelopes the enzymes, Rubisco and Carbonic Anhydrase (CA). These microcompartments facilitate the diffusion of bicarbonate ions which are converted to CO by CA, following in an increase in carbon flux near Rubisco boosting CO fixation process.

Structural analysis of genetic variants of the human tumor suppressor Palb2 coiled-coil domain.

The tumor suppressor PALB2 is a key player in the Homologous Recombination (HR) pathway, functionally connecting BRCA proteins at the DNA damage site. PALB2 forms homodimers via its coiled-coil domain, and during HR, it forms a heterodimeric complex with BRCA1 using the same domain. However, the structural details of the human PALB2 coiled-coil domain are unknown.

Disparities in Medication Prescriptions and Post-Tracheostomy Outcomes in Pediatric Patients.

Background: Granulation tissue formation and tracheitis are common pediatric tracheostomy complications. Ciprofloxacin/dexamethasone is frequently prescribed, but the influence of social determinants on this topic is unexplored.

Methods: This study extends a prior cohort study of pediatric tracheostomy patients at a single academic institution from 2016 to 2020.

The impact of sleep and exercise on brain atrophy in mild cognitive impairment.

Chronic sleep deprivation and lack of physical exercise may have detrimental effects on overall health, particularly in terms of brain health, with significant implications for cognitive function and well-being. This review explores the impact of chronic sleep deprivation and physical exercise on brain atrophy in mild cognitive impairment (MCI) and Alzheimer's disease (AD). Drawing insights from 40 selected studies, the review synthesizes evidence on these lifestyle factors' correlations with neurodegenerative changes.

Converging inputs compete at the lateral parabrachial nuclei to dictate the affective-motivational responses to cold pain.

The neural mechanisms of the affective-motivational symptoms of chronic pain are poorly understood. In chronic pain, our innate coping mechanisms fail to provide relief. Hence, these behaviors are manifested at higher frequencies.
