Cell lines with high passage numbers exhibit alterations in cell morphology and functions. In the present work, C2C12 skeletal muscle cells with either low (< 20) or high (> 60) passage numbers (identified as 1-C2C12 or h-C2C12, respectively) were used to investigate the apoptotic response to H2O2 as a function of culture age h-C2C12. We found that older cultures (h-C2C12 group) were depleted of mitochondrial DNA (mtDNA). When we analyzed the behavior of Bad, Bax, caspase-3 and mitochondrial transmembrane potential, we observed that cells in the h-C2C12 group were resistant to H2O2 induction of apoptosis. We propose serially cultured C2Cl2 cells as a refractory model to H2O2-induced apoptosis. In addition, the data obtained in this work suggest that mtDNA is required for apoptotic cell death in skeletal muscle C2C12 cells.

Soil salinization adversely impacts plant and soil health. While amendment with chemicals is not sustainable, the application of bioinoculants suffers from competition with indigenous microbes. Hence, microbiome-based rhizosphere engineering, focussing on acclimatization of rhizosphere microbiome under selection pressure to facilitate plant growth, exhibits promise.

Purpose Of The Review: Accidental autoerotic death, more commonly known as "autoerotic asphyxia," is an extreme paraphilic behavior wherein individuals induce cerebral hypoxia during self-stimulated sexual activities, often by constricting the neck or obstructing respiratory passages. Data on accidental deaths caused by autoerotic play is very low because of the non-disclosure of the mode/circumstances of death or non-paralleled forensic systems in many countries. There is a high likelihood of coexisting mental disorders with such behavior.

Rhabdomyolysis or Crush syndrome-related AKI (RM/CS-AKI) has high mortality, and there is no effective early on-site treatment method. The critical pathogenic factor of RM/CS-AKI is the excessive free myoglobin (Mb) in blood circulation. Here, based on the concept of creating a "mobile barrier", we develop an anti-Mb rabbit monoclonal antibody (RabMAb) with high specificity, affinity, stability, and broad species reactivity.

Protein aggregation, a major concern in biopharmaceutical quality control, can be accelerated by various stresses during clinical handling. This study investigated potential aggregation risk factors during dilution process with syringe handling for intravenous administration. Using γ-globulin and IgG solutions as surrogate models of antibody therapeutics, we examined the effects of high sliding speeds and piston operations of the syringe on protein aggregation during saline dilution.
