Published: October 2003

[structure: see text] A dyad of eosin and tris(2,2'-bipyridine)Ru(II) was prepared, and its photophysical properties were investigated. The photosensitization of eosin is greatly enhanced by introduction of tris(2,2'-bipyridine)Ru(II), which is verified via photooxygenation of anthracene derivatives. The electron-transfer mechanism of photosensitization is also discussed.

Primary Sjögren's syndrome (pSS) is a systemic autoimmune disease known to affect exocrine glands, leading to symptoms such as dry eyes and mouth. However, pSS can manifest in other systems, including rare genitourinary presentations. Urinary retention, although unusual, has been associated with pSS throughout the disease, particularly when related to neurogenic bladder dysfunction.

Unusual and Persistent Free Radical Intermediate Production from 2-Pyridyl Ketones via UV Irradiation: A Direct ESR Study.

J Phys Chem Lett

November 2024

State Key Laboratory of Environmental Chemistry and Ecotoxicology, Research Center for Eco-Environmental Sciences, University of Chinese Academy of Sciences, Beijing 100085, P. R. China.

Aryl ketones are often used as photosensitizers and photoinitiators. Free radical intermediates have been suggested, but not confirmed, to be generated after photoirradiation. Here we found, unexpectedly, that a persistent radical was produced from di-2-pyridyl ketone after UV irradiation, which was detected by the direct ESR method.

Article Synopsis
  • Kindler syndrome (KS) is a rare skin condition that starts in babies and causes painful blisters, unusual skin color changes, and sensitivity to sunlight as they get older.
  • It happens because of a problem with a protein called kindlin-1, which helps skin cells stick together and move properly.
  • People with KS can have issues with their mouths that are often missed or treated wrong, and having diabetes can make these problems worse, leading to bigger challenges with healing and skin issues.

Article Synopsis
  • Scientists have created special nanofibrous membranes (NFMs) that can clean the air, protect against viruses, and help diagnose respiratory diseases.
  • * They used a smart technique to make these membranes stronger and more effective by mixing different types of materials and adding tiny particles.
  • * The membranes are also good for the environment, as they can break down naturally, and they work well even in humid conditions while also helping to recognize different breathing patterns using advanced technology.

Article Synopsis
  • A young anemic woman developed liver failure and swelling after taking ferrous sulfate, leading to the discovery of her congenital erythropoietic porphyria (CEP) through a skin exam and lab tests.
  • She received treatment that included IV methylprednisolone, blood transfusions, vitamins, and wound care.
  • The report highlights the need for doctors to be aware of CEP, as it can be mistaken for other conditions and reactions due to its rarity.
