Premature ejaculation (PE) is considered the most common male sexual disorder, affecting up to 75% of men at some point in their lives. While medical management is the mainstay of therapy, surgical options such as dorsal nerve neurectomy (DNN), hyaluronic acid (HA) gel glans penis augmentation, and circumcision have been studied as alternative forms of treatment. Preliminary studies have sugges...

Smart polymeric systems represent promising means of delivering the drugs; these polymers undergo sol-gel transition, once administered. In-situ gel structure occurs due to one or combination of different stimuli like pH change, temperature modulation and ionic exchange. The formation of gels depends on factors like temperature modulation, pH change, presence of ions and ultra violet irradiatio...

We describe swelling-driven curving in originally straight and non-homogeneous beams. We present and verify a structural model of swollen beams, based on a new point of view adopted to describe swelling-induced deformation processes in bilayered gel beams, that is based on the split of the swelling-induced deformation of the beam at equilibrium into two components, both depending on the elastic...

Raman spectroscopy are used to characterize the chemical changes in normoxic polyhydroxyethylacrylate gel dosimeter (PHEA) induced by radiation. Irradiations in the low dose region are performed and the polymerizations of PHEA gels are monitored by the observing the changes of Raman shift intensity of the carbon covalent bond of PHEA originated from both monomer and the cross-linker. The variat...

Research on the characteristics of seaweed Gelidium sp from Lampung waters and its agar has been done. This study aims to look at harvested by collectors produced. Seaweed is wild main producing area in Lampung, Krui. The quality parameters observed were moisture content, impurities clean anhydrous weed (CAW) as well yield. While gel strength, gelling point melting point. results showed that an...

Following the recent demonstration of differences in mRNA species in the Novikoff hepatoma and normal rat liver (2), a search was made for differences in the abun dant cytosol proteins of these tissues as well as of several Morris hepatomas and other rat tissues. With the aid of 2dimensional electrophoresis, it was found that each of the nontumorous tissues had a distinctive pattern of abundant...

Porphobilinogen deaminase has been purified and crystallized from an overproducing recombinant strain of Escherichia coli harbouring a hemC-containing plasmid which has permitted the purification of milligram quantities of the enzyme. Determination of the Mr of the enzyme by SDS/polyacrylamide-gel electrophoresis (35,000) and gel filtration (32,000) agrees with the gene-derived Mr of 33,857. Th...

Two-dimensional (2D) gel electrophoresis allows separation of complex mixtures of proteins based on isoelectric points and relative mobility. This method has not changed much fundamentally since their original description in the late 1970s. Despite several limitations, such as solubilization of membrane proteins and separation of highly basic proteins, this method has been used successfully in ...

The properties (e.g., viscosity, sol-gel transition, and mechanical characteristics) of polysaccharides are crucial for their food applications. This work discloses how xanthan gum (XG) incorporation tailors the performance an agar/konjac glucomannan (KGM) system. As reflected by rheological thermal analyses, increasing content XG added could strengthen chain entanglement in resulting ternary s...
