Synthesis of fluorescent dicyanomethylenevinyl-1,3-dicoumarin compounds with donor-acceptor-π-donor (D-A-π-D) system and investigation of their photophysical, NLO, and chemosensor properties: Part 1.

Coumarin compounds have heterocyclic core with different properties such as high quantum yields, broad Stokes shifts, and superior photophysical and biological activity. It is known that fluorescence properties increase with increased intramolecular charge transfer in systems where electron-withdrawing or donor groups are attached to different positions of the coumarin compound. When these compounds interact with analytes in the environment, the analytes in the environment can be detected by quenching or increasing fluorescence.

EFFECT OF KYPHOPLASTY ON PAIN CONTROL AND VERTEBRAL RESTORATION.

Background And Aim: Numerous studies have been conducted regarding vertebral restoration, development of kyphotic deformity, and pain control following balloon kyphoplasty. However, there is no consensus regarding the ideal time to perform kyphoplasty. Herein, we aimed to compare the results of treatment of different vertebral levels following early or late kyphoplasty.

Investigation of the Effect of Tenoxicam on Neural Tube Defect Using Chick Embryo Model.

Aim: To evaluate tenoxicam's effects on embryonic neural tube formation to identify potential teratogenicity and determine the underlying mechanisms leading to neural tube defects (NTDs).

Material And Methods: This study was conducted at our University's Neuro-embryology Laboratory. A total of 100 fertile chicken eggs were opened using the windowing method after 24 hours of incubation.

Possible Early Examples of Medical Tourism.

Health tourism has hundreds of years of history, most notably in visitors traveling to thermal baths. Medical tourism, a type of health tourism, has rapidly expanded in the last quarter century by patients travelling abroad to health centers for medical treatment. Because of lack of records in ancient times, the history of tourism for actual medical treatment is unknown.

Boosted acceleration of protons by tailored ultra-thin foil targets.

We report on a detailed experimental and numerical study on the boosted acceleration of protons from ultra-thin hemispherical targets utilizing multi-Joule short-pulse laser-systems. For a laser intensity of 1 × 10 W/cm and an on-target energy of only 1.3 J with this setup a proton cut-off energy of 8.
