Synthesis, characterization, and investigation of photochemical and in vitro properties of novel Zn(II) phthalocyanine.

A new nonperipheral zinc(II) phthalocyanine bearing octa carboxylic acid ethyl ester derivative substituted triazole attached propylmercaptothiobenzylmercapto derivative was synthesized via the tetramerization reaction of phthalonitrile. The photochemical in vitro photodynamic activity of zinc(II) phthalocyanine (), such as human nonsmall cell lung carcinoma cell lines, was investigated in this study. The singlet oxygen generation property of novel zinc(II) phthalocyanine () was also examined due to the significantly high singlet oxygen quantum yield of (F = 0.

Morphometric evaluation of the left atrioventricular valve complex and its clinical relations.

Background: In this study, it was aimed to evaluate morphometrically and morphologically the left fibrous ring, mitral leaflets, tendinous cords, and papillary muscles, which are the components of the left atrioventricular valve complex (LAVC), and to reveal their clinical relationships.

Materials And Methods: A total of 120 human hearts were examined at the Forensic Medicine Institute. Cases aged 30 years and older, less than 24 hours after their death, were included in the study.

Evaluation of novel cosmetic shampoo formulations against Malassezia species: Preliminary results of anti-dandruff shampoo formulations.

Objectives: Malassezia species are common, clinically relevant, and lipid-dependent yeasts of humans. They are also the leading causes of the dandruff problem of humans, and the azoles are used primarily in their topical and systemic treatment. Resistance to azoles is an emerging problem among Malassezia sp.

[Investigation of Cryptococcus Colonization and Mating Genotype in Environmental Samples].

Cryptococcus species are fungal pathogens that pose a serious threat to human life and can cause meningoencephalitis in immunocompromised and healthy individuals. It was estimated that approximately 112000 people die every year due to cryptococcal-related infections all over the world, especially in immunocompromised individuals. Cryptococcus species can be found in soil, bat dung, pigeon droppings, and various tree species in addition to humans.

Monitoring SARS CoV-2 antibodies positivity in healthcare workers after inactivated CoronaVac vaccine.

Introduction: In this study, we aimed to monitor anti-spike and anti-nucleocapsid antibodies positivity in healthcare workers (HCWs) vaccinated with two doses of inactivated CoronaVac (Sinovac, China) vaccine.

Methods: Overall, 242 volunteer HCWs were included. Of the participants, 193 were HCWs without history of prior documented COVID-19 (Group 1), while 49 had history of prior documented COVID-19 before vaccination (Group 2).
