In rat pancreatic islets, β-cell gene expression, survival, and subsequent acute glucose stimulation of insulin secretion (GSIS) are optimally preserved by prolonged culture at 10 mM glucose (G10) and markedly altered by culture at G5 or G30. Here, we tested whether pharmacological glucokinase (GK) activation prevents these alterations during culture or improves GSIS after culture. Rat pancreat...

Dendrimer-based nanotechnology significantly advances the area of targeted cancer imaging and therapy. Herein, we compared the difference of surface acetylated fluorescein isocyanate (FI) and folic acid (FA) modified generation 5 (G5) poly(amidoamine) dendrimers (G5.NHAc-FI-FA), and dendrimer-entrapped gold nanoparticles with similar modifications ([(Au(0))(51.2)-G5.NHAc-FI-FA]) in terms of the...

To analyze outcomes and toxicities of stereotactic body radiotherapy with helical tomotherapy (HT-SBRT) for inoperable lung tumors, the medical records of 30 patients with 31 lung tumors treated with HT-SBRT were reviewed. The 3-year local control, cause-specific survival and overall survival rates (LC, CCS and OS, respectively) were analyzed using the Kaplan-Meier method. Toxicities were grade...

Mice lacking Niemann-Pick C1-Like 1 (NPC1L1) (NPC1L1(-/-)mice) exhibit a defect in intestinal absorption of cholesterol and phytosterols. However, wild-type (WT) mice do not efficiently absorb and accumulate phytosterols either. Cell-based studies show that NPC1L1 is a much weaker transporter for phytosterols than cholesterol. In this study, we examined the role of NPC1L1 in phytosterol and cho...

objective: generation 5 poly (amidoamine) dendrimers are promising multipotent gene delivery vectors that provide favorable dna condensation properties; however, their high toxicity limits their applications. toxicity of pamam dendrimers depends on their type, generation and applied dosage in a way that lower generations (lower than g5 dendrimers) and anionic dendrimers have lower toxicity than...

Tryptase, a protease produced by all mast cells, was evaluated as a clinical marker of systemic mastocytosis. Two sandwich immunoassays were evaluated, one which used the mAb G5 for capture, the other which used B12 for capture. The B12 capture assay measured both recombinant alpha- and beta-tryptase, whereas the G5 capture assay measured primarily recombinant beta-tryptase. G5 binds with low a...

Three soils of different content gypsum and lime were selected, the first soil (G1) second (G3), obtained near fields Faculty Agriculture, Tikrit University. As for third (G5), was taken from AL- alam Village side east city to a depth (0-10)cm. proportions 5%, 15%, 25%, 20%, 10% G1, G3, G5, respectively. Ferrous sulfate added as source iron ions three in following (0,10,25,50,100,150,250,500,75...
