Comparative analysis of plasma affinity depletion methods: Impact on protein composition and phosphopeptide abundance in human plasma.

Affinity-based protein depletion and TiO enrichment methods play a crucial role in detection of low-abundant proteins and phosphopeptides enrichment, respectively. Here, we assessed the effectiveness of HSA/IgG (HU2) and Human 7 (HU7) depletion methods and their impact on phosphopeptides coverage through comparative proteome analysis, utilizing in-solution digestion and nano-LC-Orbitrap mass spectrometry (MS). Our results demonstrated that both HU2 and HU7 affinity depletion significantly decreased high-abundant proteins by 1.

Modulation of plant polyamine and ethylene biosynthesis; and brassinosteroid signaling during Bacillus endophyticus J13-mediated salinity tolerance in Arabidopsis thaliana.

Salinity stress adversely impacts plant growth and development. Plant growth-promoting rhizobacteria (PGPR) are known to confer salinity stress tolerance in plants through several mechanisms. Here, we report the role of an abiotic stress-tolerant PGPR strain, Bacillus endophyticus J13, in promoting salinity stress tolerance in Arabidopsis thaliana, by elucidating its impact on physiological responses, polyamine (PA) and ethylene biosynthesis, and brassinosteroid signaling.

Bilateral adrenal cortical rests: An interesting innocuous intruder in the fallopian tubes.

Ectopic adrenal rests refer to the presence of adrenal tissue outside its normal anatomical location and are usually discovered incidentally on microscopic examination. Literature suggests its occurrence in diverse extrarenal sites, like the genitourinary system and pelvis. Our case describes the rare occurrence of ectopic adrenal rests in the walls of bilateral fallopian tubes of a 43-year-old female patient who presented with a complaint of heavy menstrual bleeding.
