Calcium oxalate is a common biomineral in plants, occurring as crystals of various shapes. It can be found in any tissue or organ in plants and is often formed in the vacuoles of specialized cells called crystal idioblasts. Recent work indicates that calcium oxalate formation is generally a mechanism for regulating bulk-free calcium levels in tissues ...

Calcium Oxalate Urolithiasis in Cats
Journal of Endourology, 1999Urolithiasis has long been recognized as a cause of irritative voiding in cats. Before the late 1980s, sterile struvite was the most common urolith; today, however, 40% of feline uroliths are of calcium oxalate. This change may be partly attributable to the change to urine-acidifying, magnesium-restricted diets that were introduced to reduce the ...

Idiopathic Calcium Oxalate Urolithiasis and Endogenous Oxalate Production [PDF]
Journal of Urology, 1996 Despite the great effort that has gone into investigating urolithiasis, this condition still persists as one of the major ailments of the urinary tract. Calcium oxalate urolithiasis is the most common form, accounting for some 60 to 80% of total stones.

Calcium Oxalate Urolithiasis: A Case of Missing Microbes?
Journal of endourology, 2018INTRODUCTION Urinary stone disease (USD) has known associations with the gut microbiota. Approximately 80% of kidney stones contain oxalate as a primary constituent and diverse oxalate-degrading bacteria exist within the human gut, which may protect ...

Oxalate: effect on calcium absorbability
The American Journal of Clinical Nutrition, 1989Absorption of calcium from intrinsically labeled Ca oxalate was measured in 18 normal women and compared with absorption of Ca from milk in these same subjects, both when the test substances were ingested in separate meals and when ingested together. Fractional Ca absorption from oxalate averaged 0.100 +/- 0.043 when ingested alone and 0.140 +/- 0.063 ...

Urologia Internationalis, 1987
Since about 85% of synthesized calcium oxalate dihydrate (COD) crystals proved not to have changed into calcium oxalate monohydrate (COM) crystals at 30 min of incubation time at 37 degrees C when our evaluation method of the COD-to-COM ratio was being used, we made a comparative study of the inhibitory effects of magnesium, one of the well-known ...

Journal of Urology, 1985
According to the theoretical expression for calibration curve as a function of the optical absorption ratio of two peaks and with the analysis of the infrared spectra of the mixture samples of commercial calcium oxalate monohydrate and synthesized calcium oxalate dihydrate, the following quadratic equation was obtained; Y = 1.79 X2 - 30.90 X + 107.04 ...

Calcium oxalate crystal morphology
Trends in Plant Science, 2002Plants invest considerable resources of carbon and calcium in crystal formation, indicating that it is an important basic process in growth and development. The diversity of crystal shapes, as well as their prevalence and spatial distribution, have led to several hypotheses regarding crystal function in plants.
