Due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. The temperature effect on the swelling properties of commercial polyacrylic acid (PAA) hydrogel beads was investigated as a function of time and temperature. Gel bead size, swelling equilibr...

BACKGROUND Heat therapy is one of the most popular non-pharmacological treatments for osteoarthritis of the hand. OBJECTIVES To investigate the therapeutic and chemical effects of Hévíz mud on patients with hand osteoarthritis. METHODS We randomly assigned 47 patients with mild-to-moderate hand osteoarthritis to two groups. Patients in group 1 (n=23) received Hévíz mud applied directly to b...

BACKGROUND Vitamin D displays immunomodulatory activities and has been proposed as a potential player in the pathogenesis of rheumatoid arthritis (RA). A negative association between serum 25(OH) vitamin D levels and RA activity was demonstrated but longitudinal studies investigating the role of vitamin D levels in predicting RA activity and response to treatment are lacking. Therefore, this st...

Farber disease caused by acid ceramidase deficiency is characterised by a triad of painful and swollen joints, subcutaneous nodules, and laryngeal involvement. A one year old female with overlapping features of the classical and type 5 variants is reported. Sialuria and elevated plasma chitotriosidase were unusual findings. A novel mutation of the ASAH 1 gene was detected from DNA extracted fro...

Hypoxic necrosis of dentate gyrus neurons in primary culture required the activation of an orderly cell death program independent of protein synthesis. Early mitochondrial swelling and loss of the mitochondrial membrane potential were accompanied by release of cytochrome c and followed by caspase-9-dependent activation of caspase-3. Caspase-3 and -9 inhibitors reduced neuronal necrosis. Calcium...

cotton fibres were subjected to cleaning process and then characterized for maturity. decrystallisation and swelling processes with caustic soda, ethanol, propan-2-ol and trichloroethene on the native fibres were carried out. the effects of these on the strength and moisture regain were investigated. the activation energies of the dyeings were also analysed with durazol scarlet red 4 bas. the r...

using controlled drug delivery devices is one of the novel methods of drug delivery which is used to perform drug therapy with the minimum side effects. mucoadhesive polymers are one of these devices. chitosan is a natural polymer which is a suitable candidate for this purpose due to it is biocompatibility, bioadhesion and high capability to adsorb peptide drugs. since gi tract has both acidic ...

introduction: hydatid disease caused by larval stage of echinococcus has been recognized endemically in many countries. liver and lungs are the most commonly affected organs. involvement of the head and neck region is rare and bony erosion due to hydatidosis is even rarer. case report: we report a case of a 17-year-old girl from a poor socio-economic background who presented with a right sided ...

We have investigated here the mechanism of dephosphorylation and activation of death-associated protein kinase (DAPK) and the role of lysosome in neuroblastoma cells (SH-SY5Y) treated with mitochondrial toxins, such as MPP(+) and rotenone. Mitochondrial respiratory chain inhibitors and uncouplers decreased mitochondrial membrane potential leading to DAPK dephosphorylation and activation. The cl...
