Combination therapy of multiple drugs through a single system is exhibiting high therapeutic effects. We investigate nanocarrier mediated inhibitory effects of topotecan (TPT) and quercetin (QT) on triple negative breast cancer (TNBC) (MDA-MB-231) and multi drug resistant (MDR) type breast cancer cells (MCF-7) with respect to cellular uptake efficiency and therapeutic mechanisms as in vitro and in vivo. The synthesized mesoporous silica nanoparticle (MSN) pores used for loading TPT; the outer of the nanoparticles was decorated with poly (acrylic acid) (PAA)-Chitosan (CS) as anionic inner-cationic outer layer respectively and conjugated with QT...

OBJECTIVES: To detect post-operative sequelae of sural nerve biopsy. MATERIALS AND METHODS: A questionnaire mailed to type 1 diabetic patients (n = 24; male/female 23/1; reply n = 23) 2 years after biopsy. RESULTS: Type 1 diabetic patients (age 56 [11]; median [interquartile range]) had a long duration of diabetes (DM; 20 [19] years) and all had neuropathy. Three out of 24 patients developed infection (two superficial and one deep) and one had a post-operative bleeding...

BACKGROUND: We have previously shown that insulin is not a major risk factor for CHD. Our data have been re-analysed with longer follow-up and the homeostasis model assessment (HOMA) method. DESIGN: Prospective cohort study of 57- and 67-year-old men. METHODS: Insulin resistance was estimated with the HOMA equation. Standard methods were used to measure risk factors. The endpoint (CHD) was the combination of non-fatal myocardial infarction and fatal CHD during 13 years of follow-up...

We examined 3 groups of elderly men; men with diabetes and previous or present foot ulcers, men with diabetes, and men without diabetes. In the foot diseased group, diabetes duration was longer (18 +/- 11 vs 8 +/- 7 years), insulin treatment was more common (86% vs 7%), fasting blood glucose and HbA1c were significantly higher (10.5 +/- 4.0 mmol/1, 8.4% +/- 1.6%) than in the diabetic control group (8.3 +/- 3.4 mmol/l, 7.4 +/- 1.7%). Men in the foot diseased group were taller than men in the diabetic group and non-diabetic men (1...

The present study was undertaken with the aim of evaluating the effect of multiple insulin injection therapy with an insulin pen in a large population of type 1 and type 2 diabetes patients and to investigate which factors predict a favorable response to the therapy change. We included 100 type 1 and 51 type 2 patients with a minimum diabetes duration of 1 year who were followed for at least 3 years after changing from conventional insulin regimens to multiple insulin injection therapy with the pen. Both type 1 and type 2 patients were significantly improved with respect to metabolic control at 3 months...

The role of the renin angiotensin system for the regulation of kidney function in diabetes mellitus is uncertain. Results from studies in diabetic animals suggest that a reduced activity in this system contributes to the renal hyperperfusion and hyperfiltration in diabetes. The renal sensitivity to angiotensin II in diabetic patients is also unknown. Changes in renal hemodynamics were measured after infusion of two low doses of angiotensin II in ten young type 1 diabetic patients without complications and in ten healthy controls...
