Weak and weathered rocks are well known for their sensitivity to changes in moisture content. Degrading behavior is common weak with moisture-sensitive mineral components present numerous stability problems. The slake durability a measure of the resistance weakening disintegration rock materials which quantitatively distinguishes durable from non-durable materials. Several material parameters i...

Chitosan-pectin, chitosan-alginate and chitosan-pectin-alginate scaffolds were prepared by freeze-drying technique. The physicochemical characteristics of the scaffolds were characterized by FTIR and SEM. The biological activities like antibacterial assessment, swelling behavior, biodegradation and cytotoxicity study of the prepared scaffolds were evaluated. The results show high swelling prope...

Electrophysiologic and morphologic changes during cooling and perfusion with preservation solutions in isolated perfused proximal straight tubules from Swiss white mice were investigated. In standard Ringer-substrate solution, cooling from 37 degrees C to 22 and 4 degrees C depolarized both transepithelial potential and basolateral cell membrane potential. Basolateral k+ transference number and...

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...

In this report, a case of adult onset fatal cerebral oedema as a rare complication of diabetic ketoacidosis (DKA) is described and confirmed at post-mortem pathological examination. The pathogenesis of cerebral oedema due to DKA is still unknown. Potential mechanisms include the administration of sodium bicarbonate leading to intracellular acidosis, excessive fluid infusion causing swelling of ...

Background Context: In the United States, the most prevalent cause of disability of workers under 45 years of age is low back pain. Past research suggests that there is a link between low back pain and intervertebral disc degeneration. One of the earliest known components of disc degeneration is a decrease in proteoglycan content in the nucleus pulposus, which in turn leads to changes in mechan...
