The purpose of the study was to develop an optimized thermoreversible in situ gelling ophthalmic drug delivery system based on Pluronic F 127, containing moxifloxacin hydrochloride as a model drug. A 3(2) full factorial design was employed with two polymers: Pluronic F 68 and Gelrite as independent variables used in combination with Pluronic F 127. Gelation temperature, gel strength, bioadhesio...

In this paper, polyacrylamide/chromium acetate gel polymer system was prepared as water shut-off system to control water production in one of the Iranian oil reservoirs condition. Effect of various parameters such as temperature (90 °C) and water formation from view point of salinity and divalent cations, was evaluated on the gelation kinetic and gel strength using bottle testing method. Th...

HMB has recently become a popular dietary supplement used to promote exercise performance and skeletal muscle hypertrophy by many exercise enthusiasts. A lot of previous studies have found that HMB supplement is beneficial to reduce muscle damage and decrease protein catabolism, which leads to increased gains in muscle size and strength when associated with resistance exercise. However, it is v...

The pBR322 plasmid contains genes encoding for tetracycline and ampicillin resistance. Escherichia coli DH5α cells with pBR322 plasmid were grown and plated on selective plates containing 1) ampicillin only and 2) tetracycline only with varying antibiotic concentrations of half strength, three-fourth strength and full strength (15 μg/mL tetracycline and 50 μg/mL ampicillin for full strength). C...

OBJECTIVE To evaluate in vitro the effects of tooth whitening using gel with Amorphous Calcium Phosphate (ACP) on the bond strength of metal brackets. METHODS Thirty-six bovine incisors were sectioned at the crown-root interface, and the crowns were then placed in PVC cylinders. The specimens were divided into 3 groups (n = 12) according to whitening treatment and type of gel used, as follows...

Milk was thermally processed by Ultra-High-Temperature (UHT, 132 to 154 C for 0 to 12 sec) and Vat (VAT, 66 C to 88 C for 0 to 30 min) systems. Representative milks were fermented into gels by a traditional yoghurt fermentation procedure. Selected functional properties, i.e. whey protein denaturation, gel strength, and their interrelationship were studied. Denaturation behavior of the five whey...
