Kinetic Characterisation of the R and R2 Quaternary Structures of Oxyhemoglobins Arising from Different Effects of Inositol Hexakisphosphate on Their Reactions with Ellman's Reagent.

In a previously reported equilibrium study of the reaction of 5,5'-dithiobis(2-nitrobenzoate), DTNB, with various carbonmonoxyhemoglobins over the pH range 5.6 to 9, we obtained contradictory results on the influence of the allosteric effector inositol hexakisphosphate (inositol-P) on the DTNB reaction. For this reason, we replaced the carbonmonoxyhemoglobins with oxyhemoglobins and investigated the effect of inositol-P on the equilibrium and of their reactions with DTNB over the same pH range.

Microglial senescence in neurodegeneration: Insights, implications, and therapeutic opportunities.

The existing literature on neurodegenerative diseases (NDDs) reveals a common pathological feature: the accumulation of misfolded proteins. However, the heterogeneity in disease onset mechanisms and the specific brain regions affected complicates the understanding of the diverse clinical manifestations of individual NDDs. Dementia, a hallmark symptom across various NDDs, serves as a multifaceted denominator, contributing to the clinical manifestations of these disorders.

Chemical composition and digestible and metabolizable energy contents in cold-pressed canola expellers fed to growing pigs.

Cold-pressed canola expellers () are a byproduct of canola oil production obtained using the pressing method without thermal and chemical treatment. While CPCE is a valuable source of dietary energy and protein in swine nutrition, the discrepancy in processing conditions leads to variability in the nutritional quality of CPCE from different sources. This study aimed to determine the chemical composition, and digestible energy () and metabolizable energy () values of CPCE when fed to growing pigs.

Target capture sequencing for the first Nigerian genotype I ASFV genome.

African swine fever (ASF) is a contagious viral disease that affects domestic pigs and wild boars, causing significant economic losses globally. After the first Nigerian outbreak in 1997, there have been frequent reports of ASF in pig-producing regions in the country. To facilitate control, it is important to understand the genotype and phylogenetic relationship of ASF viruses (ASFVs).

Necroptosis in the developing brain: role in neurodevelopmental disorders.

Cell death is vital to various organismal developmental processes including brain development. Apoptosis, the most recognized programmed cell death, has been linked to several developmental processes and implicated in pruning cells to provide the ultimate tissue integrity. However, more recently, other forms of non-apoptotic programmed cell death have been identified, of which necroptosis is of predominant interest.
