Pressure ulcers result from immobility and continuous pressure on an area of body. Besides imposing further restriction of movements and thus creating a vicious circle in the healing process, these ulcers are of significant importance in decreasing the life quality and increasing the costs of treatment in these patients. In this study we compared the outcome of treatment of pressure ulcers with...

1. Plasma aluminium concentration and urinary aluminium excretion were monitored for 4.5 h in rats after the administration of 25 micrograms or 800 micrograms of aluminium as an intravenous bolus, either as aluminium chloride or as aluminium citrate (i.e. aluminium chloride together with sodium citrate). 2. Immediately after the bolus aluminium administration, the plasma aluminium concentration...

S x ~ , B i i and Chappelll have reviewed in The Lancet neurochemical aspects of the interaction of aluminium (Al) with physiological ligands, emphasishg the preference of this neurotoxin for association with oxygen donor p u p s , especially cytosolic phosphates. We would add to their argument the potential for Al to interact with nucleic acid polyphosphates. This is of neurotoxological intere...

Sevelamer hydrochloride is the first non-aluminium, non-calcium-based phosphate binder developed for the management of hyperphosphatemia in end stage renal diseases. It is a synthetic ion-exchange polymer which binds and removes phosphate ions due to the high content of cationic charge associated with protonated amine groups on the polymer matrix. This is the first in-depth study investigating ...

Based on the optimal proportion of resin and curing agent, an ultrahigh-temperature inorganic phosphate adhesive was prepared with aluminum dihydric phosphate, aluminium oxide ( α -Al₂O₃), etc. and cured at room temperature (RT). Then, nano-aluminum nitride (nano-AlN), nano-Cupric oxide (nano-CuO), and nano-titanium oxide (nano-TiO₂) were added into the adhesive. Differential scanning calorimet...

Investigation of aluminium uptake by human erythrocytes was the major aim of this study. Packed red blood cells were incubated in Earle's medium (pH 7.4) containing varying concentrations of aluminium (0-160 /lg/J) as AIK(SO.), and aluminium content of the cells were determined using flameless atomic absorption. There was significant increase in aluminium content of the cells. Addition of 5...

Hyperphosphataemia is a frequent and important cardiovascular risk factor in patients with chronic kidney disease (CKD). High phosphate levels may influence vascular calcifications by two separate mechanisms: by worsening secondary hyperparathyroidism, which in turn facilitates calcification, and by promoting calcium phosphate deposition in pre-formed endothelial plaques and in the arterial wal...

The effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male Wistar rats were investigated. Daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations ...
