Normal calcium oxalate crystal growth inhibition in severe calcium oxalate nephrolithiasis. [PDF]

Journal of the American Society of Nephrology, 1996
Urine from mammalian kidneys is regularly supersaturated with respect to calcium oxalate monohydrate, the most common solid phase in human nephrolithiasis, and also inhibits the nucleation, growth, and aggregation of calcium oxalate crystals. Nephrolithiasis is often associated with increased supersaturation, and it is assumed that this increase ...

Extraction of calcium, oxalate and calcium oxalate crystals from sesame seeds.

BUNSEKI KAGAKU, 1994
ごまを粉砕し,粉砕ごまから沸騰水中に遊離のカルシウム及びシュウ酸を抽出した.又0.1M塩酸中にカルシウム及び全シュウ酸を抽出した.抽出液中のカルシウム及びシュウ酸をAAS及びイオンクロマトグラフィーで測定した.一方,ごまを水と共にミキサーで摩砕し,混合物をビーカーに移し,静置した.沈降したシュウ酸カルシウム結晶をデカンテーション法で上澄み液を注意深く流し出して集めた.ごまの種類によるが,洗いごま100gにつき,遊離のカルシウム70mg,遊離のシュウ酸350mg,全シュウ酸1750mg,シュウ酸カルシウム-水和物2320mgとなり,全カルシウムを1200mgとすればシュウ酸カルシウム以外のカルシウムは565mgとなった.結晶はシュウ酸カルシウム-水和物であり,球形の凝集体をしていた.

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.

An Oxalyl-CoA Dependent Pathway of Oxalate Catabolism Plays a Role in Regulating Calcium Oxalate Crystal Accumulation and Defending against Oxalate-Secreting Phytopathogens in Medicago truncatula

PLoS ONE, 2016
Considering the widespread occurrence of oxalate in nature and its broad impact on a host of organisms, it is surprising that so little is known about the turnover of this important acid. In plants, oxalate oxidase is the most well studied enzyme capable

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 ...

Effect of citrate on the urinary excretion of calcium and oxalate: relevance to calcium oxalate nephrolithiasis.

Clinical Chemistry, 1989
Abstract Studies in 24 recurrent oxalate stone-formers have shown that values for urinary calcium excretion for this group on at-home diets vary significantly (P less than 0.001) more than values for creatinine excretions. By placing stone-formers on controlled in-hospital diets and measuring their calcium excretions, we were able to ...

Electrochemical Degradation of Plastic Waste Coupled with Hydrogen Evolution in Seawater Using Rosette‐Like High‐Entropy Oxides

Advanced Science, EarlyView.
Rosette‐like high‐entropy NiCoFeMnAlOx enable the electrochemical degradation of PGA plastic waste in seawater, coupling glycolic acid oxidation with hydrogen evolution. Abundant OH* species lower energy barriers for C─C and C─H bond activation, while in situ and theoretical studies reveal the catalytic mechanism.

Toward Complete CO2 Electroconversion: Status, Challenges, and Perspectives

Advanced Energy Materials, EarlyView.
Electrocatalytic CO2 reduction and CO2 batteries face challenges in achieving complete CO2 conversion with high conversion rates and Faradaic efficiency simultaneously. Existing systems compromise one for the other with incomplete CO2 conversion and inefficiencies, hindering practical applications. This perspective highlights state‐of‐the‐art progress,

A Case of Chronic Calcium Oxalate Nephropathy due to Short Bowel Syndrome and Cholecystectomy

Case Reports in Nephrology and Dialysis, 2018
Background: Oxalate nephropathy is a rare disease. Especially chronic oxalate nephropathy still has many unknown aspects as compared to acute oxalate nephropathy with relatively well-known causality. Case Presentation: The patient was a 70-year-old woman
