Basic Information of Dextran

Chemical Name: Dextran

Cas No.: 9004-54-0

Molecular Formula: H(C6H10O5)xOH

Chemical Structure:

 

 

Dextran is a complex branched glucan (polysaccharide made of many glucose molecules) composed of chains of varying lengths (from 3 to 2000 kilodaltons). The straight chain consists of α-1,6 glycosidic linkages between glucose molecules, while branches begin from α-1,3 linkages. This characteristic branching distinguishes a dextran from a dextrin, which is a straight chain glucose polymer tethered by α-1,4 or α-1,6 linkages.

Medicinally it is used as an antithrombotic (antiplatelet), to reduce blood viscosity, and as a volume expander in hypovolaemia. Dextran 70 is on the WHO Model List of Essential Medicines, the most important medications needed in a health system.

These agents are used commonly by microsurgeons to decrease vascular thrombosis. The antithrombotic effect of dextran is mediated through its binding of erythrocytes, platelets, and vascular endothelium, increasing their electronegativity and thus reducing erythrocyte aggregation and platelet adhesiveness. Dextrans also reduce factor VIII-Ag Von Willebrand factor, thereby decreasing platelet function. Clots formed after administration of dextrans are more easily lysed due to an altered thrombus structure (more evenly distributed platelets with coarser fibrin. By inhibiting α-2 antiplasmin, dextran serves as a plasminogen activator, so possesses thrombolytic features.

Although relatively few side effects are associated with dextran use, these side effects can be very serious. These include anaphylaxis, volume overload, pulmonary edema, cerebral edema, or platelet dysfunction. An uncommon but significant complication of dextran osmotic effect is acute renal failure. The pathogenesis of this renal failure is the subject of many debates with direct toxic effect on tubules and glomerulus versus intraluminal hyperviscosity being some of the proposed mechanisms. Patients with history of diabetes mellitus, renal insufficiency, or vascular disorders are most at risk. Brooks and others recommend the avoidance of dextran therapy in patients with chronic renal insufficiency.

¿Por qué la tecnología de OPT SHR hair removal sigue siendo popular en el mundo?

Usando la tecnología SHR, el método de eliminación del vello que involucra pigmentos capilares usa solo el 50% de la energía para la depilación permanente. Durante el tratamiento con la técnica SHR, el 50% restante se absorbe en las células madre responsables de producir el vello a través de la piel.

Con la tecnología SHR, no se requiere un solo pulso con alta energía. Use de 6 a 10 masajes de la piel con poca energía pero alta frecuencia. Este proceso se conoce como el llamado método "en movimiento" porque el asa se mueve sobre el área de tratamiento durante el movimiento de deslizamiento. (En contraste, la tecnología IPL se llama "tecnología de sellado").

Usando la tecnología SHR, la piel se calienta suavemente con melanina y células madre a baja energía (48 grados), pero a alta frecuencia. De esta manera, incluso un cabello más claro y fino se puede procesar y eliminar de forma permanente de una mejor manera. Con la tecnología IPL, la piel se puede calentar a 70 grados.

La tecnología SHR es rápida, efectiva y casi indolora.

Una cierta área del cuerpo es sensible al dolor, dependiendo del grado de vellosidad y su sensibilidad.

¿Cuántos tratamientos necesitas?

Si el cabello está en la temporada de crecimiento de la temporada de crecimiento durante el procesamiento, es decir, en la temporada de crecimiento activo, solo se destruye como tecnología de la IPL machine . Sin embargo, las personas solo necesitan entre cuatro y ocho tratamientos para garantizar la eliminación permanente del vello.

Basic Information of Pyriproxyfen

Chemical Name: Pyriproxyfen

Cas No.: 95737-68-1

Molecular Formula: C20H19NO3

Chemical Structure:

 

 

Pyriproxyfen is a pyridine-based pesticide which is found to be effective against a variety of arthropoda. It was introduced to the US in 1996, to protect cotton crops against whitefly. It has also been found useful for protecting other crops. It is also used as a prevention for flea control on household pets, for killing indoor and outdoor ants and roaches. Methods of application include aerosols, bait, carpet powders, foggers, shampoos and pet collars.

Pyriproxyfen is a juvenile hormone analog and an insect growth regulator. It prevents larvae from developing into adulthood and thus rendering them unable to reproduce.

Pyriproxyfen is an insect growth regulator. It mimics natural insect hormones that stop young insects from maturing into adults. Pyriproxyfen can affect an insect if it is touched or eaten. However, pyriproxyfen is rarely toxic to adult insects. Instead, it disturbs egg-laying and egg-hatch and keeps young insects from growing into adult forms. This prevents target insects from multiplying.

 

LEAPChem is continually expanding its scope within the pharmaceutical chemicals industry. Our passion for professional development enables us to accommodate our customers’ chemical requirements, and to distribute chemicals with applications that span several classes and functions.
