Renal Physiology and Water Homeostasis Modules (Out of Print)

open access: yesMedEdPORTAL, 2006
This resource is a series of eight interactive, animated modules covering renal physiology and water homeostasis. At our institution, target learners were first-year medical students in our integrated human organ systems physiology-histology course.

Formation mechanism of thermally controlled pH gradients

open access: yesCommunications Physics, 2023
Cells use pH gradients to drive the synthesis of adenosine triphosphate (ATP), but the physicochemical mechanisms that can produce pH gradients in non-equilibrium settings are poorly understood.

Influence of pH, Temperature and Impurities on the Solubility of an Active Pharmaceutical Ingredient (API) [PDF]

open access: yes, 2010
Solubility, which defines the liquid /solid equilibrium, is a key parameter to control a crystallization process. This work is focused on the effects of pH, temperature and impurities on the aqueous solubility of an Active Pharmaceutical Ingredient (API).

ESTABLISHING CORRELATION OF pH WITH VARIOUS PHYSIOCHEMICAL AND TRADITIONAL PARAMETERS OF ACID BASE BALANCE: A CROSS-SECTIONAL STUDY

open access: yesKhyber Medical University Journal, 2022
OBJECTIVE: To evaluate the effectiveness of Physiochemical versus traditional approach in diagnosing acid-base disorders (ABD). METHODS: This cross-sectional observational study was conducted on 212 patients, admitted during January to June 2020, in ...

Startup of a reactive distillation process with a decanter [PDF]

open access: yes, 2008
The startup of a reactive distillation process for the production of propyl acetate including a decanter is studied. A simulation model is presented which describes the whole startup from a cold and empty state and takes into account the liquid phase ...

Molecular Characteristics of Water-Insoluble Tin-Porphyrins for Designing the One-Photon-Induced Two-Electron Oxidation of Water in Artificial Photosynthesis

open access: yesMolecules, 2023
Faced with the new stage of water oxidation by molecular catalysts (MCs) in artificial photosynthesis to overcome the bottle neck issue, the “Photon-flux density problem of sunlight,” a two-electron oxidation process forming H2O2 in place of the ...

Zinc Sorption to Three Gram-Negative Bacteria: Combined Titration, Modeling, and EXAFS Study [PDF]

open access: yes, 2006
The acid-base and Zn sorption properties of three bacteria, Cupriavidus metallidurans CH34, Pseudomonas putida ATCC12633, and Escherichia coli K12DH5R, were investigated through an original combination of extended X-ray absorption fine structure (EXAFS ...

Edible insects exert a high potential renal acid load to the human kidneys

open access: yesInternational Journal of Food Properties, 2023
The potential renal acid load (PRAL) describes the capacity of a food to produce acid or base in the human body. The long-term consumption of high-PRAL diets induces a chronic low-grade metabolic acidosis state that has been associated with inflammation ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
