The aim of this work was to study the release mechanisms of drugs having different solubility (buflomedil pyridoxalphosphate 65%, sodium diclofenac 3.1%, nitrofutantoin 0.02% w/v,) from hydroxypropyl methylcellulose (HPMC) matrices by concomitantly studying swelling, diffusion and erosion fronts movement and drug delivery. The main goal was to clarify the role played by polymer swelling in drug...

Supramolecular cross-linked porous lignin based poly (acrylic acid) [LBPAA] was lab-synthesized by copolymerizing lignin grafted N, N'-methylene-bisacrylamide (LM) and acrylic acid. LBPAA successfully acted as a water retention agent with salt resistance and biodegradation for agricultural applications. Lignin was found to improve its swelling behaviors with higher water retention, fast swellin...

The effect of carbon black on the mechanical properties of elastomers is of great interest, because the filler is one of principal ingredients for the manufacturing of rubber products. While fillers can be used to enhance the properties of elastomers, including stress-free swelling resistance in solvent, it is widely known that the introduction of fillers yields significant inelastic responses ...

Nude athymic (nu/nu) mice on a BALB/c background and their heterozygous euthymic litter mates (nu/+) were infected with either 10(8) or 10(6) Mycobacterium lepraemurium organisms intravenously or in the left hind footpad (LHF). After LHF infection with 10(8) M. lepraemurium organisms, nu/+ mice slowly developed a response that consisted of LHF swelling and local resistance to Listeria monocytog...

background:  sternocostoclavicular joint (sccj) swelling is an underdiagnosed, albeit important entity in clinical practice. the present study was conducted in order to identify the incidence and common causes of this entity.  methods:  patients presenting to the orthopaedic clinic with a swelling of the sternocostoclavicular joint, during the study period of two years were included, and detail...

cationic copolymer gels of acrylamide and [(methacrylamido) propyl] trimethyl ammonium chloride (maptac) were synthesized by free radical aqueous solution polymerization. the taguchi method, a robust experimental design, was employed for the optimization of the synthesis based on the equilibrium swelling capacity of the hydrogels. based on taguchi method a standard l16 orthogonal array with fiv...

[Purpose] The purpose of this study was to investigate the effects of a strategic strength resistance exercise program on the isokinetic muscular function of the ankle joint. [Subjects] This study included 22 males in their twenties who were diagnosed with functional injury of the ankle joint. [Methods] To strengthen plantar flexion and dorsiflexion of the ankle joint, 8 weeks of weight, resist...
