Impact of Virus‐Mediated Modifications in Bacterial Communities on the Accumulation of Soil Organic Carbon

Advanced Science, EarlyView.
This study illustrates the impact of viruses on carbon cycling in soils with different availabilities of carbon. In conditions of low carbon availability, viruses adopt a lysogenic lifestyle, integrate into the host genomes and facilitate the degradation of carbon.

Hyperoxaluria leads to dysbiosis and drives selective enrichment of oxalate metabolizing bacterial species in recurrent kidney stone endures

Scientific Reports, 2016
Hyperoxaluria due to endogenously synthesized and exogenously ingested oxalates is a leading cause of recurrent oxalate stone formations. Even though, humans largely rely on gut microbiota for oxalate homeostasis, hyperoxaluria associated gut microbiota ...

Plasma oxalic acid and calcium levels in oxalate poisoning [PDF]

Journal of Clinical Pathology, 1967
Observations are reported on five cases of suicide or attempted suicide by poisoning with oxalic acid or ethylene glycol. Elevated oxalic acid levels were observed in the plasma, stomach contents, and a number of tissues. Raised oxalic acid levels in plasma were associated with reduced total and ultrafilterable calcium levels.

WTAP Mediated m6A Modification Stabilizes PDIA3P1 and Promotes Tumor Progression Driven by Histone Lactylation in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study reveals a new mechanism by which PDIA3P1 regulates the progression of esophageal squamous cell carcinoma (ESCC). PDIA3P1 upregulates the expression of GLUT1 and HK2, promoting glycolysis and lactate production. Lactate upregulates the lactylation level of histone H4K8 and activates the transcription of target gene BMP7, ultimately ...

Histopathologic Perspective of Combined Liver–kidney Transplant: In Primary Hyperoxaluria Type 1 Patient

Indian Journal of Transplantation
Primary hyperoxaluria (PH) type 1 is a rare autosomal recessive disorder of glyoxylate metabolism. Its prevalence is 1–3 cases/million people. Glyoxylate is the precursor of oxalate which is believed to be produced by oxidation in liver peroxisomes ...

No Reported Renal Stones with Intravenous Vitamin C Administration: A Prospective Case Series Study

Antioxidants, 2018
A few cases associating high dose intravenous vitamin C (IVC) administration with renal stone formation have been reported in the literature, however, no long-term studies investigating IVC administration and reported renal stones have been carried out ...

Oxygen Activation by Mononuclear Mn, Co, and Ni Centers in Biology and Synthetic Complexes [PDF]

, 2017
The active sites of metalloenzymes that catalyze O2-dependent reactions generally contain iron or copper ions. However, several enzymes are capable of activating O2 at manganese or nickel centers instead, and a handful of dioxygenases exhibit activity ...

Nitric acid scavenging by mineral and biomass burning aerosols [PDF]

, 1998
The abundance of gas phase nitric acid in the upper troposphere is overestimated by global chemistry-transport models, especially during the spring and summer seasons.

Oxalobacter formigenes-Derived Bioactive Factors Stimulate Oxalate Transport by Intestinal Epithelial Cells.

Journal of the American Society of Nephrology, 2017
Hyperoxaluria is a major risk factor for kidney stones and has no specific therapy, although Oxalobacter formigenes colonization is associated with reduced stone risk. O. formigenes interacts with colonic epithelium and induces colonic oxalate secretion,

Stirring Without Stirrers: Polymer Fouling‐Driven Mass Transport Unlocks Order‐of‐Magnitude Gain in Electrochemiluminescence

Advanced Science, EarlyView.
Strategic electrode fouling enhances mass transport, primarily through electrochemically actuated lateral density gradients. Engineered fouling induces flow velocities up to 0.4 cm s⁻¹ in otherwise quiescent systems. Sub‐millimeter plastic features boost local rates by up to 290%, while micrometer‐scale arrays yield a 30% net electrolysis gain ...
