The triglyceride-glucose index as a predictive marker for coronary slow flow phenomenon.

OBJECTIVE: The triglyceride-glucose index (TyG) has been proposed as a marker of insulin resistance (IR) and has shown associations with cardiovascular diseases. This study aimed to investigate the relationship between the TyG and the coronary slow flow phenomenon (CSFP) and explore the index's potential as a predictor of this condition. PATIENTS AND METHODS: A total of 187 patients who underwent coronary angiography were included; of these, 91 patients were diagnosed with CSFP, and 96 patients with normal coronary flow served as a control group. The TyG was calculated using fasting triglyceride and glucose levels. RESULTS: The results showed that the TyG was significantly higher in the CSFP group compared with the control group (p < 0.001). Additionally, the TyG exhibited a moderate positive correlation with the thrombolysis-in-myocardial-infarction frame count in coronary arteries (p < 0.001). A multivariate logistic regression analysis revealed that the TyG, along with gender, ejection fraction, and uric acid, remained significant predictors of CSFP (p < 0.05). CONCLUSIONS: This study's findings suggest that the TyG may serve as a useful marker for identifying individuals at risk of CSFP and provide insights into the potential role of IR in its pathophysiology.

An investigation on systematic history and distribution areas of tarek (Alburnus tarichi (Güldenstädt, 1814)) / Uma investigação sobre a história sistemática e as áreas de distribuição de tarek (Alburnus tarichi (Güldenstädt, 1814))

Abstract This study aimed to determine the distribution area of tarek (Alburnus tarichi (Güldenstädt, 1814)) and to define how it must be called according to the scientific name by evaluating its previous studies made by various systematisers and their reports on its distribution, and by comparing literature knowledge. The taxonomic characteristics of the collected samples were evaluated and several measurements and counts were taken on the samples; analfin origin 0-4 scales behind dorsal fin-base; 72-91 lateral line scales; 21-29 gill rakers; 7½-10 branched dorsal-fin rays and 10-12½ branched anal-fin rays. Body and caudal peduncle was moderately compressed. Body was covered by overlapping scales. Tarek has five different populations in the Basin. They are Van, Erçek, Nazik and Aygır Lakes and Koçköprü Dam Lake populations. The main living area of the tarek population is Lake Van; however, between May and June, mature individuals of tarek enter to tributaries of Van Lake. Some of them are Karasu, Bendimahi, Deliçay, Zilan, Karmuç, Sapur, Yanıkçay, Gevaş, Engil, Kurubaş and Akköprü Streams. At the end of study, it was concluded that tarek should be called as Alburnus tarichi (Güldenstädt, 1814) and it is an endemic fish species distributed only in Van Lake Basin.

Resumo Este estudo teve como objetivo determinar a área de distribuição de tarek (Alburnus tarichi) (Güldenstädt, 1814) e definir como deve ser chamado de acordo com o nome científico, avaliando estudos anteriores feitos por vários sistematizadores e seus relatórios sobre sua distribuição, e comparando o conhecimento da literatura. As características taxonômicas das amostras coletadas foram avaliadas e várias medições e contagens foram realizadas nas amostras, como origem analfin 0-4 escalas atrás da base da barbatana dorsal; 72-91 escalas de linha lateral; 21-29 rakers branquiais; 7½-10 raios da nadadeira dorsal ramificada, e 10-12½ raios da nadadeira anal ramificados. Pedúnculo caudal e corporal foram moderadamente comprimidos. O corpo estava coberto por escamas sobrepostas. Tarek tem cinco populações diferentes na bacia estudada. São as populações dos lagos Van, Erçek, Nazik e Aygır, e Koçköprü barragem. A principal área de presença da população tarek é o Lago Van; no entanto, entre maio e junho, indivíduos maduros de tarek entram nos afluentes do lago Van. Alguns deles são os fluxos Karasu, Bendimahi, Deliçay, Zilan, Karmuç, Sapur, Yanıkçay, Gevaş, Engil, Kurubaş e Akköprü. No final do estudo, concluiu-se que tarek deveria ser chamado Alburnus tarichi (Güldenstädt, 1814) e que é uma espécie de peixe endêmica distribuída apenas na Bacia do Lago Van.
