Alkali burn injury is a true ocular emergency of the conjunctiva and cornea that requires immediate precision. Lack of an immediate therapy can lead to a substantial damage in the ocular surface and anterior segment further causing visual impairment and disfigurement. We explored the regenerative capability of dominant negative survivin protein (SurR9-C84A) and histone deacetylase inhibitor tri...
This research aimed to analyze the change in chemical composition of betung bamboo (Dendrocalamus asper) strands after alkali immersion treatment under various times. The culms were converted into with target length, width, and thickness 70, 25, 0.5 mm, respectively. Strands immersion-treated 1% NaOH solution for 1, 2, 3 h. Preparation powder component analysis refers Technical Association Pulp...
Porous NiTi alloys has a series of unique properties such as shape memory effect, superelastic behavior and energy absorbability that make them usable in a wide range of medical and industrial appliances. But the more probability of Ni release from a porous NiTi compare to the nonporous one has restricted it’s uses in implants. In the present research for resolving the problem, performing a cal...
Jerusalem artichoke (Helianthus tuberosus L.) is emerging as one of the energy plants considered for biofuel production. Alkali and alkali-involved pretreatment methods have been widely used bioconversion cellulosic materials due to their high sugar yield low inhibitor release. However, recovery treatment wastewater (black liquor) poorly studied. Here, we present a novel two-stage process desig...
At present, thermal storage is considered as one of the key technologies to alleviate problem instability and intermittence for renewable energy. Due relatively high latent heat, heat by molten salt a potential technology. Because restriction different thermophysical parameters, application has many technical obstacles. So, it an urgent work find better mixed formula with comprehensive properti...
This paper describes the experimental investigation carried out to develop the geopolymer concrete based on alkali-activated rice husk ash (RHA) by sodium hydroxide with sodium silicate. Effect on method of curing and concentration of NaOH on compressive strength as well as the optimum mix proportion of geopolymer mortar was investigated. It is possible to achieve compressive strengths of 31 N/...
BACKGROUND The biorefinery based on an effective and economical process is to fractionate the three primary constituents (cellulose, hemicelluloses, and lignin) from lignocellulosic biomass, in which the constituents can be respectively converted into high-value-added products. In this study, a successive treatment with dilute acid (0.25-1.0 % aqueous H2SO4, 100-150 °C, 0.5-3.0 h) and alkali (1...
this thesis aims at putting together two of the vestest areas of study there is in humanities: bioethics and literature. the two novels in question, oryx and crake and the year of the flood, are considered as some of the most succssful examples of spculative fiction. in these novels the biological and environmental issues raised as looked at from a bioethics point of view.
To understand the corneal regeneration induced by bevacizumab, we investigated the structure changes of stroma and basement membrane regeneration. A Stick soaked in 0.5 N NaOH onto the mouse cornea and 2.5 mg/ml of bevacizumab was delivered into an alkali-burned cornea (2 μl) by subconjunctival injections at 1 hour and 4 days after injury. At 7 days after injury, basement membrane regeneration ...
Four proteoglycans were sequentially extracted from Hypsizygus marmoreus using 0.1 M NaOH (alkali-soluble proteoglycans [F1] and alkali-insoluble proteoglycans [F3]) and 0.1 M HCl (acid-soluble proteoglycans [F2] and acid-insoluble proteoglycans [F4]), and their structures and immunomodulatory activities were investigated. The proteoglycans were found to contain carbohydrates (19.8-82.4%) with ...
