Effects of Ketamine on Penile Tissues in an Experimental Priapism Model in Rats
(Turkish Assoc Trauma Emergency Surgery, 2024) Gevrek, Fikret; Fırat, Fatih; Unsal, Velid; Tapar, Hakan; Karaman, Tugba; Karaman, Serkan; Yalçın, Kenan
BACKGROUND: This study aimed to evaluate the histopathological and biochemical effects of ketamine on penile tissues following ischemia-reperfusion injury induced by priapism. METHODS: Twenty-four male rats were randomized into three groups. Group 1 served as the control group. Group 2 underwent the priapism model to induce ischemia-reperfusion injury. Group 3, the treatment group, experienced a similar ischemia-reperfusion model as Group 2; additionally, 50 mg/kg of ketamine was administered intraperitoneally just before reperfusion. Blood biochemical analyses and penile histopathological evaluations were performed. RESULTS: In Group 3, significant improvements were observed in all histopathological scores, including desquamation, edema, inflammation, and vasocongestion compared to Group 2 (p<0.001). Blood biochemical analyses showed that the malondialdehyde (MDA) levels were recorded as 10 in Group 2, with a significant decrease in Group 3 (p=0.013). Similarly, proinflammatory cytokine levels, including interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α), were found to be suppressed in Group 3 compared to Group 2 (p=0.003, p=0.022, and p=0.028, respectively). Antioxidant enzyme activities, such as glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD), were higher in Group 3 compared to Group 2 (p=0.016 and p=0.024, respec- tively). CONCLUSION: Ketamine is an effective anesthetic agent in alleviating the effects of penile ischemia-reperfusion injury.

Fatty Acid Composition of Root and Shoot Samples of Some Astragalus L. (Fabaceae) Taxa Growing in the East and Southeast of Turkey
(Tubitak Scientific & Technological Research Council Turkey, 2013) Keskin, Cumali; Kacar, Semra
The fatty acid compositions of root and shoot samples of some Astragalus L. (Fabaceae) taxa [A. gossypinus Fisch., A. amblolepis Fisch., A. edmondi (Kuntze) Sheld., A. tigridis Boiss., A. aleppicus Boiss., A. suberosus Banks & Sol. subsp. suberosus Banks & Sol., A. gummifer Labill., A. diphtherites Fenzl var. diphtherites Fenzl, and A. gymnalopecias Rech.f.] growing in the east and southeast of Turkey were determined by gas chromatography. Astragalus species contained palmitic (C 16:0) (20.13%-53.8%), linoleic (C 18:2 omega-6) (13.25%-41.06%), oleic (C 18:1 omega-9) (5.78%-25.7%), linolenic (C 18:3 omega-3) (6.1%-22.89%), and stearic acid (C 18:0) (5.16%-13.1%) in the roots and linolenic (8.9%-51.42%), palmitic (20.16%-44.88%), linoleic (7.34%-27.57%), oleic (2.45%-17.91%), and stearic acid (4.28%-8.31%) in the shoots as major components. In this study the fatty acid composition of Astragalus species showed uniform fatty acid patterns. Palmitic and stearic acids were the major saturated and linoleic and linolenic acids were the major unsaturated fatty acids in the roots and shoots.

Seasonal effect on fatty acid composition in phospholipid classes and triacylglycerols of male Capoeta umbla
(CSIC Consejo Superior de Investigaciones Cientifica, 2023) Kaçar, Semra; Kayhan Kaya, Hacer; Başhan, Mehmet; 09.03. Department of Nutrition and Dietetics/ Beslenme ve Diyetetik Bölümü; 9. Faculty of Health Sciences / Sağlık Bilimleri Fakültesi; 01. Mardin Artuklu University / Mardin Artuklu Üniversitesi
The seasonal changes in muscle tissue, total lipids and fatty acid composition of phospholipids (PL), triacylglycerol (TAG), and phospholipid classes of male Capoeta umbla were investigated in this study. Phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylinositol (PI), and phosphatidylserine (PS) were identified as the major phospholipids (PLs) in the muscle tissue (PS). Triacylglycerols showed high contents of MUFA, 14:0, 16:1n-7, 18:1n-9, 18:2n-6, and 18:3n-3; while phospholipids presented high contents of AA, DHA, and 18:0. Myristic acid, 16:1n-7, 18:1n-9, monounsaturated fatty acids (MUFA), linoleic acid (18:2n-6), and linolenic acid (18:3n-3) were shown to be present in larger concentrations in TAG than in PL classes. In PL classes, 16:0, 18:0, arachidonic acid (20:4n-6) (AA), eicosapentaenoic acid (EPA) (20:5n-3), docosahexaenoic acid (DHA) (22:6n-3) and polyunsaturated fatty acid (ΣPUFA) were higher than the TAG fraction. The fatty acid composition of total lipid and lipid classes (TAG and PL) were affected by the seasonal variations and lipid fraction.

Volatile Compounds, Bioactive Properties and Chlorophylls Contents in Dried Spearmint (Mentha Spicata L.) as Affected by Different Drying Methods
(Galenos Publ House, 2023) Korkmaz, Aziz; Arslan, Erhan; Kosan, Meltem
This study presents a comparison of the quality characteristics of spearmint (Mentha spicata L.) dried by a photovoltaic thermal dryer (PVT), the shade dried spearmint (SDS), and an oven dried spearmint (ODS). The obtained samples were evaluated with respect to volatile compounds (VC), total phenolic content (TPC) and flavonoid content (TFC), antioxidant capacity (AC) and chlorophylls (Chl) contents. PDS had the highest amount of TPC, TFC and AC, while SDS and ODS did not differ significantly from each other in terms of these features. SDS exhibited the highest Chl a and Chl b contents, whereas ODS showed the lowest. The composition of VC in the dried spearmints was significantly affected by the drying methods used. The total amount of terpenoids, especially carvone, responsible for spearmint's characteristic aroma in SDS was higher than those of the others, while the concentrations of most VC were lowest in ODS. According to the results, the PVT can be recommended for drying spearmint.
