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.

Exercise and endometriosis-is there a promising future? A narrative review.

Background: Endometriosis is the leading cause of chronic pelvic pain in women of reproductive age with debilitating effects on quality of life, yet no cure exists. Exercise yields the potential in providing women with a non-invasive, non-pharmacological method of symptom control.

Aim(s): Present up-to-date knowledge regarding how exercise may contribute to the management of endometriosis-related symptoms.

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.

Occurrence and characterization of Proteus mirabilis from infected farmed African catfish in Ogun State, Nigeria.

Background: Bacterial pathogens are the causative agents of some of the most serious disease problems in cultured fish causing mortalities and severe economic losses. This study was conducted to determine the occurrence and characterization of Proteus mirabilis from infected farmed African catfish in Ogun State, Nigeria.

Methodology: The bacteria were isolated from diseased farmed African catfish (Clarias gariepinus, n=128) with clinical signs of skin haemorrhages, ulceration, and ascites purposively sampled from farms within three senatorial districts namely Ogun East (OE; n=76), Ogun Central (OC; n=30) and Ogun West (OW; n=22) in Ogun State.
