Information about Anti-Dengue Antibody




Dengue is an infectious disease caused by the Dengue virus, it is belong to Aedes (also called Edith mosquito, Aedes) of white spot mosquito (Aedes albopictus) with Egypt spot mosquito, Aedes aegypti) after the first bite patients, become "vector mosquitoes," other healthy people could be infected by this vector mosquitoes. Likely excessive fatigue and depression symptoms, accidentally the sick will deteriorate to dengue to spill blood heat, and further bleeding, shock, and even death.

The main purpose of the Sodium fluoride



Sodium fluoride: shine colorless crystals or white powder, specific gravity 2.25, melting point 993 ℃ the boiling point of 1695 ℃. Soluble in water (20 ° C solubility 10 ° C 3.66, 4.06, 4.22, 40 °, 30 ° C C 4.4, 60 ° C 4.68, 4.89, 100 °, 80 ° C C5.08), hydrofluoric acid, slightly dissolve into alcohol. Weakly alkaline aqueous solution, but soluble in hydrofluoric acid and hydrogen fluoride sodium, can corrode the glass. Poisonous!
Main application: in coating industry for phosphating accelerator, stability of the phosphating liquid and phosphating refinement, improvement of phosphating film performance. Aluminum and its alloy phosphating damaging, closed a large negative catalysis of Al3 +, phosphating smoothly wood preservative, agricultural pesticides, fungicides, medicine, preservatives, welding flux, alkaline zincate galvanized additive and enamel, paper industry, etc.

Isoflurane anesthesia is a good medicine





Isoflurane can rapid induction of anesthesia, the patient recovered from anesthesia is faster. Isoflurane had mild irritation, which limits its induction rate, but the throat and the trachea bronchial secretion is not much. Throat reflection can alleviate quickly. Isoflurane anesthesia level changes quickly. The drug is a kind of deep breathing inhibitors, therefore must pay close attention to breathing and provide respiratory support when necessary. Anesthesia increase, reduce tidal volume but breathing rate unchanged. Respiratory depression can part by surgical stimulation inside. Sigh isoflurane can stimulate sexual response, similar to that of desflurane anesthesia in the ether and grace to see, but the frequency is far lower than the desflurane.
Anesthesia to blood pressure lowering but operations to stimulate the deflection to the normal direction. Anesthesia level increases with the corresponding drop in blood pressure. N2O reduction in inhaling isoflurane concentration, so the blood pressure lowering effect is weak in the use of isoflurane. Rhythm of the heart no abnormal change. Under the condition of the control of ventilation and PaCO2, cardiac output by increasing heart rate compensation per the decrease of cardiac output and maintain stability. Naturally occurring in the process of ventilation hypercarbia blood disease further stimulate the heart rate increases, the cardiac output is higher than the level of the waking state. Isoflurane can't make the experimental dog myocardial adrenaline increased sensitivity of exogenous. Limited experimental data show that subcutaneous injection of 0.25 mg epinephrine for isoflurane anesthesia patients of ventricular arrhythmias without aggravating tendency.

The principle of Palladium carbon catalyst





Palladium - chemical symbol Pd, it is silvery white metal, soft, good ductility and plasticity, forging, rolling and drawing. Block metal palladium can absorb a large amount of hydrogen gas, make significant swelling volume, brittle or even broken into pieces
Carbon palladium catalyst is formed in the metal palladium load to activated carbon type load hydrofining catalyst, used to deal with the refining terephthalic acid raw material, the production of purified terephthalic acid. Carbon palladium catalyst has the different process of PTA filling quantity, such as Beijing, Shanghai yanshan petrochemical, liaoyang petrochemical, luoyang petrochemical and tianjin petrochemical refining enterprises, the successful industrial application.

What is Nandrolone ?




Nandrolone (19-nortestosterone) is an anabolic steroid. Nandrolone is a lot of frequently awash commercially as its decanoate ester (Deca-Durabolin) and beneath frequently as a phenylpropionate ester (Durabolin). Nandrolone decanoate is acclimated in the analysis of osteoporosis in postmenopausal women (though now not recommended) at a dosage of 50 mg every three weeks. It is aswell acclimated for some aplastic anemias.
