Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Evaluation of the Effects of Intravenous Ascorbic Acid on Correction of Anemia in Renal Failure Patients Undergoing Hemodialysis

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2006
Introduction: Hemodialysis patients often develop resistance to recombinant human erythropoietin due to functional Iron Deficiency. In these patients iron therapy can be hazardous leading to hemosiderosis.

Innate Immunocompetent hiPSC‐Derived Neurospheroids Capture Early CNS Responses to rAAV

Advanced Science, EarlyView.
Knowledge of human CNS immune responses to AAV‐based gene therapies remains limited due to the lack of immune‐competent human models. Here, a hiPSC‐derived 3D neuroimmune platform integrating neurospheroids and microglia is established using stirred‐tank bioreactors.

Sustainable Fabrication of Tailored Bone Substitutes: From High‐Throughput Scaffold Manufacturing, Scaled‐Up HMSC Expansion to Dynamic Cultivation in a Perfusion Bioreactor

Advanced Science, EarlyView.
ABSTRACT The demand for off‐the‐shelf biocompatible bone substitutes has driven the development of numerous independent in vitro technologies to generate products resembling physiological tissues. Due to technical challenges and overly simplified cultivation approaches/niches, the end‐products are often uniformly shaped and inferior to native bone ...

Successful management of methemoglobinemia with oral ascorbic acid: Dual case reports

MRIMS Journal of Health Sciences
Methemoglobinemia is a rare blood disorder characterized by elevated levels of methemoglobin (MetHb), leading to a reduced capacity of red blood cells to carry oxygen, resulting in functional hypoxia and cyanosis.

Effects of ascorbic acid deficiency on adrenal mitochondrial hydroxylations in guinea pigs.

Journal of Lipid Research, 1978
The effect of ascorbic acid deficiency on adrenal hydroxylation of cholesterol and deoxycorticosterone in guinea pigs was studied by using mitochondria and isolated cytochrome P-450 fractions.

PREPARATION AND CHARACTERIZATION OF TOPICAL FORMULATIONS CONTAINING 6-O-ALKYL DERIVATIVES OF ASCORBIC ACID [PDF]

, 2009
Alkyl vitamin C derivatives (ASCn) are amphiphilic molecules having physicochemical properties that depend on the alkyl chain length. The derivatives with low molecular weight (n < 11) have enough aqueous solubility to produce self-assemblies at room ...

Remote Magnetomechanical Neuromodulation Uncovers Therapeutic Mechanisms for Alleviating Parkinsonian Symptoms in Freely Moving Mice

Advanced Science, EarlyView.
Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Silicon attenuates calcium deficiency by increasing ascorbic acid content, growth and quality of cabbage leaves

Scientific Reports, 2021
Calcium (Ca) deficiency in cabbage plants induces oxidative damage, hampering growth and decreasing quality, however, it is hypothesized that silicon (Si) added to the nutrient solution may alleviate crop losses.
