Scientists create new hydrogel super skin that heals by 90% in just four hours Scientists created a new hydrogel that mimics human skin and rapidly heals: A team of scientists from Aalto University and the University of Bayreuth has developed a revolutionary hydrogel that mimics human skin's dual traits-toughness and self-repair. This new material can heal itself within hours thanks to an intricate network of polymer chains entangled around nanosheets, offering strength without sacrificing flexibility. The breakthrough, published in Nature Materials, could accelerate innovation in artificial skin, wound healing, and soft robotics where materials that can stretch, bend, and recover from damage are critical. The hydrogel forms when a UV lamp triggers the bonding of polymer monomers, creating an elastic solid with up to 10,000 layers of nanosheets per millimeter. Cut the gel, and it begins healing immediately -recovering 90% of its integrity in just four hours and completely within a ...

study about Valerian

-
Image
  Valerian (valeriana officinalis) ·   Part used :    Whole underground parts, including the rhizome surrounded by the roots and stolon’s. Constituents : a)   1-Volatile oils 0.5-2% : NLT 0.5% of volatile oil, and NLT 0.17% of total valerenic acids, calculated on the dried basis. b)  2- Iridoids (valepotriates) : Valerates, didrovaltrates and isovalerates groups. The valepotriates are unstable and decompose on storage or processing. Note : valerian is preferably to be administered as a herb tea or well-preserved pharmaceutical products. c)    3- Alkaloids (Pyridine type): e.g. valerianine and valerine. d)   4- Other constituents : Amino acids (e.g. arginine, y- aminobutyric acid (GABA) which argued if small or substantial amount can pass BBB (R3) , caffeic and chlorogenic acids (polyphenolic).   Active Constituents: The sedative activity attributed to both the volatile oil and iridoid valepotriate (highly unstable)...

Captopril use as ACE inhibitor

-
Image
  Captopril Captopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat high blood pressure, heart failure, and certain kidney conditions. ·   Captopril is a sulfhydryl-containing analogue of proline with antihypertensive activity & antineoplastic activity. ·    Captopril is a specific competitive inhibitor of angiotensin I-converting enzyme (ACE) that enzyme responsible for the conversion of angiotensin I to angiotensin II. Captopril is a white to off-white crystalline powder that may have a slight sulphurous odour; it is soluble in water, methanol, & ethanol and sparingly soluble in chloroform and ethyl acetate.  Discovery of Captopril ·    One of the first drugs marketed for lowering blood pressure was found by studying the venom from Bothrops jararaca, a poisonous snake. Captopril, an analog of the snake venom's ACE-inhibiting peptide, was first synthesized in 1975 by three researchers at the U.S. drug company E.R....
