Effect of composition of interpenetrating polymer network hydrogels based on poly(acrylic acid) and gelatin on tissue response: a quantitative in vivo study.

The local tissue response of the biomaterial is the most important criteria for determination of its biocompatibility. In the present study, full and semi-interpenetrating polymer networks (IPN) based on polyacrylic acid (AAc) and gelatin (Ge) crosslinked with 0.5 mol % N,N'-methylene bisacrylamide (BAm) and 4% glutaraldehyde (GA), respectively, were evaluated for tissue response in rats.

Protection against acute adriamycin-induced cardiotoxicity by garlic: role of endogenous antioxidants and inhibition of TNF-alpha expression.

Background: Oxidative stress is the major etiopathological factor in adriamycin-induced cardiotoxicity. Relatively low amounts of endogenous antioxidant makes the heart vulnerable to oxidative stress-induced damage. Chronic oral administration of garlic has been reported to enhance the endogenous antioxidants of heart.

Expression of biomarkers modulating prostate cancer angiogenesis: differential expression of annexin II in prostate carcinomas from India and USA.

Background: Prostate cancer (PCa) incidences vary with genetic, geographical and ethnic dietary background of patients while angiogenesis is modulated through exquisite interplay of tumor-stromal interactions of biological macromolecules. We hypothesized that comprehensive analysis of four biomarkers modulating angiogenesis in PCa progression in two diverse populations might explain the variance in the incidence rates.

Results: Immunohistochemical analysis of 42 PCa biopsies reveals that though Anx-II expression is lost in both the Indian and American population with Gleason scores (GS) ranging between 6 and 10, up to 25 % of cells in the entire high grade (GS > 8) PD PCa samples from US show intense focal membrane staining for Anx-II unlike similarly graded specimens from India.

Studies on biodegradation and release of gentamicin sulphate from interpenetrating network hydrogels based on poly(acrylic acid) and gelatin: in vitro and in vivo.

Interpenetrating network hydrogels (IPNs) based on poly(acrylic acid) and gelatin (Ge) were evaluated for in vitro and in vivo biodegradation and in vivo release of gentamicin sulphate. In vitro and in vivo degradation studies demonstrated that with the increase of acrylic acid content in the polymer, the rate of degradation decreases, and a reverse phenomenon was observed with increasing Ge content in the hydrogel. The rate of in vivo degradation was much lower than in vitro degradation.

Autosomal dominant progressive nephropathy with deafness: linkage to a new locus on chromosome 11q24.

Focal segmental glomerulosclerosis (FSGS) and Alport syndrome (AS) are two major causes of end-stage renal disease (ESRD). A few families with autosomal dominant FSGS have been reported with linkage to chromosome 19q13 or 11q22, while AS is usually linked to mutations in type IV collagen (COL4) subunit genes. A phenotype resembling AS may also be seen with myosin heavy chain-9 (MYH9) gene mutations.

Intravenous cyclophosphamide in steroid-resistant nephrotic syndrome.

We prospectively examined the effect of treatment with intravenous cyclophosphamide in patients with steroid-resistant nephrotic syndrome. Twenty-four patients (minimal change disease in 11, focal segmental glomerulosclerosis in 9, and mesangioproliferative glomerulonephritis in 4), who did not show remission of proteinuria despite treatment with 8 weeks of oral prednisolone and six intravenous pulses of dexamethasone, were studied. Cyclophosphamide was administered intravenously, at a dose of 750 mg/m(2) once a month for 6 months; therapy with alternate-day prednisolone was continued.
