The significant accumulation of Pb from anthropogenic activities threatens environmental ecosystems. In the environment, iron oxides are one main carriers Pb. Thus, redox cycling oxides, which is due to biotic and abiotic pathways, leads their dissolution or transformation, controls fate However, a knowledge gap exists on bioreduction in Pb-bearing ferrihydrites, secondary-mineral precipitation...

An attempt has been made to show the difference in the penetrability of coconut oil and mineral oil in human hair. We have used secondary ion mass spectrometry (SIMS) in combination with a time-of-flight (TOF) mass spectrometer. Characteristic ions formed by the pure components when bombarded with gallium ions have been identified with their m/z values. The distribution of the ion, characterist...

Patients with chronic kidney disease-mineral and bone disorder (CKD-MBD) have a high risk of bone fracture because of low bone mineral density and poor bone quality. Osteoporosis also features low bone mass, disarranged microarchitecture, and skeletal fragility, and differentiating between osteoporosis and CKD-MBD in low bone mineral density is a challenge and usually achieved by bone biopsy. B...

There are many unanswered questions about how to manage secondary hyperparathyroidism and associated alterations in mineral metabolism in patients with end-stage renal disease. We provide commentary on an observational study by Komaba et al. that presents interesting new insights into the long-standing controversy related to the impact of parathyroidectomy on survival of hemodialysis patients.

Mineral arsenicals have long been used in traditional medicines for various diseases, yet arsenic can be highly toxic and carcinogenic. Arsenic in traditional medicines typically comes from deliberate addition for therapeutic purposes, mainly in the form of mineral arsenicals, including orpiment (As2S3), realgar (As4S4), and arsenolite (contains arsenic trioxide, As2O3). Inorganic arsenic is no...

BACKGROUND Low back pain (LBP) is chronic disease without a curative therapy. Alternative and complementary therapies are widely used in the management of this condition. OBJECTIVES To evaluate the efficacy of home application of Dead Sea mud compresses to the back of patients with chronic LBP. METHODS Forty-six consecutive patients suffering from chronic LBP were recruited. All patients we...

Laser fluorescence (LF) is thought to be a quantitative technique for the measurement of mineral loss from dental caries. These studies aimed to demonstrate the quantitative nature of LF, by means of transverse microradiography (TMR), in addition to the possible use of LF on small specimens suitable for in situ studies. Studies also aimed to determine the ability of LF to detect caries adjacent...

Ten chromite ores from ophiolite complexes in SE Iran were analyzed mineralogically by XRD, chemically by XRF, and mineral chemistry by EPMA. The identified paragenesis of silicate minerals of chromite ores with the X-ray diffraction is pronounced differently. It consists of secondary phases formed as serpentine, Cr-containing chlorite (kaemmererite), chromic garnet (uarovite) with preserved pa...
