Understanding One Health and Zoonosis: A Systematic Review with a Bibliometric Analysis of Turkish Research and Global Perspectives (1974-2023)
No full textA bibliometric analysis explored the understanding of the "One Health" and "zoonosis" concepts among Turkish researchers and identified existing gaps. The analysis examined trends in research on "One Health," "zoonosis," and "zoonoses," focusing on publications from Tiirkiye and globally. Data from Scopus were analyzed using VOSviewer and RStudio software. The results showed that research interest in these concepts has grown in Tiirkiye since the 2000s. However, the number of articles from Tiirkiye remains low compared to developed countries. The interdisciplinary nature of "One Health" and "zoonosis" research in Tiirkiye reflects contributions from various academic fields. Medical sciences lead in research, followed by immunology and veterinary sciences. In Tiirkiye, "One Health" is predominantly associated with animals, especially felines, and zoonotic pathogens such as Toxoplasma, Anthrax, and Echinococcus. It also relates to epidemiology, infectious diseases, and antibiotic resistance. Globally, "One Health" has a broader perspective, encompassing environmental health, education, veterinary medicine, and food safety. Regarding "zoonosis," Tiirkiye focuses on pathogens such as Anthrax, Echinococcus, Brucella, Leishmania, and Hantavirus. Globally, additional pathogens such as Rickettsia, Taenia solium, and Giardia are included. "Zoonosis" is also linked to climate change, animal welfare, and vector-and food-borne diseases. Despite increased interest, Tiirkiye's scientific production remains limited. Emphasis on interdisciplinary collaboration and broader conceptual frameworks could enhance understanding and research impact

Morpho-Physiological Effects of Salt Stress on Germination and Early Seedling Development in Okra (Abelmoschus esculentus L. cv. Toros Sultanı)
No full text Okra (Abelmoschus esculentus L.) is a vegetable crop known for its high nutritional value and increasing economic importance, particularly due to its adaptability to warm climate conditions. However, salinity - one of the widespread abiotic stress factors affecting agricultural lands - negatively impacts the germination and seedling development of many cultivated species, including okra. This study was conducted in 2024 at the Department of Soil Science and Plant Nutrition, Faculty of Agriculture, Erciyes University, with the objective of evaluating the effects of daily irrigation with water of different salt concentrations (0, 4, 8 and 12 dSm-1) on the germination and early seedling development of the okra cultivar ‘Toros Sultanı’. In the experiment, 50 seeds were used per treatment with five replications. A comprehensive data set consisting of 29 morpho-physiological parameters related to germination and germination matrix was measured. The results revealed that all salt treatments had statistically significant effects (p < 0.001) on all measured germination and seedling parameters. While limited reductions or signs of metabolic adaptation were observed at 4 and 8 dSm-1, the 12 dSm-1 treatment caused marked declines in several critical traits such as germination percentage, germination speed, vigor indices, root-to-shoot ratio, Timson and modified Timson indices, synchronization and emergence indices. The stress tolerance index (STI) calculations showed that the ‘Toros Sultanı’ cultivar exhibited physiological tolerance under moderate salinity but that this tolerance diminished considerably under high salinity conditions like 12 dSm-1. These findings suggest that the ‘Toros Sultanı’ cultivar holds agronomic potential for production in saline environments up to 8 dSm-1, while higher salinity levels may lead to substantial yield and emergence losses. The data generated from this study contribute to the understanding of varietal- and specieslevel adaptation mechanisms to salt stress and offer a scientific basis for future research focused on the management of saline soils.</p
Hydrochemical Characteristics of Groundwater for Drinking Purpose and Health Risk Assessment
No full textUrbanization and industrialization in many parts of the world contaminate ground and surface water resources. The present study is designed to investigate the hydrochemical characteristics, spatial distribution of major cations/anions, heavy metal pollution and associated health risk assessment of groundwater. In total 30 groundwater samples were taken from different urban localities of Multan, suggesting an elevated level of EC and TDS. Major cations and anions except SO42- and HCO3- in one area were below World Health Organization (WHO) guidelines for drinking purpose. Hydrochemical results also indicates groundwater pollution is attributed to rock-water interaction. Medium to low microbial concentration was also noted in groundwater by seepage of sewage water. Elevated heavy metal concentration (As, Cd, Cr & Fe) was recorded in most of the sampled groundwater. Piper plot indicates mixed water type with Na+/K+ and Na+/HCO3- type. Water Quality Index (WQI) and Heavy metal Pollution Index (HPI) ranked groundwater of Multan from very poor to hazardous posing health hazards. Total hazard quotient value by ingesting groundwater exceeds non-carcinogenic threshold HQ = 1.0 in half of groundwater samples. Potential cancer risk was obtained for children in selected areas. Therefore, an effective management and monitoring system is applied in study area to safeguard the local community from potential illness. Major response action require to restore groundwater quality is to cut off contamination sources such as industrial effluents, fertilizers and pesticides application. Installing water treatment plants in study area to reduce cancer risk for local community is an effective and tangible solution
Effects of Dietary Black Cumin Seed Meal on Growth Performance, Meat Quality, Rumen and Blood Parameters in Lambs
No full textThis study was conducted to investigate the effects of dietary black cumin seed meal on growth performance, meat quality, rumen and blood parameters in lambs. A total of 32 Akkaraman male lambs aged 3 months were allocated individual pens with 8 replicates and fed with experimental diets for 84 days. Experimental groups were as follows: 1: Control (C, no black cumin seed meal, BCSM), 2: BCSM supplementation to concentrate 5% (BCSM5), 3: BCSM supplementation to concentrate 10% (BCSM10), and 4: BCSM supplementation to diets 20% (BCSM20). Although dietary BCSM did not affect growth performance, blood parameters, carcass, and meat traits, BCSM increased meat cooking loss (at 5% level) and meat thawing loss (at 10 % level) compared to control and other treatments (P<0.05). BCSM also did not change rumen volatile fatty acids, except decrease in butyric acids on the 35th day of the experiment. In conclusion, when given the optimal energy: protein ratio, black cumin seed meal can be used as an alternative protein source in animal feeds since it does not negatively affect the growth performance, carcass quality and health status of lambs
Crystal structure and Hirshfeld surface analysis of dimethyl 3-methyl-8-{[4-(trifluoromethyl)phenyl]-sulfonyl}-7,8-dihydro-4H-4,6a-epoxybenzo[b]naphtho[1,8-de]azepine-5,6-dicarboxylate
No full textThe molecular conformation of the title compound, C29H22F3NO7S, is stable due to the intramolecular C—H· · ·O hydrogen bonds. The central seven-membered ring adopts a distorted chair form. In the 7-oxabicyclo[2.2.1]hepta-2,5-diene unit, the five-membered rings adopt envelope conformations. In the crystal, the molecules are linked by C—H· · ·O and C—H· · ·F interactions, forming sheets parallel to the (002) plane. Additionally, S—O· · ·π and π–π interactions [centroid-to-centroid distance = 3.6159 (7) Å ] connect the molecules along the a-axis direction. van der Waals interactions between the molecular sheets reinforce the molecular packing. A Hirshfeld surface analysis was conducted to visualize the various intermolecular interactions, indicating that the largest contribution to the surface contacts is from H· · ·H interactions (37.3%), followed by O· · ·H/H· · ·O (24.1%), F· · ·H/H· · ·F (19.0%), and C· · ·H/H· · ·C (10.3%) interactions

No full textDesign and experimental study of a helicopter seat cushion for vibration isolation
No full textVibration is defined as oscillation away from equilibrium and is a significant problem in aviation. Vibration is transmitted to the flight crew through all contact surfaces, including flight controls, floor and seats. Various effects are known to occur on flight crew exposed to vibration, with fatigue and low back pain being the most common vibration-related health complaints. Studies have shown that prolonged exposure to vibration or accumulated vibration can increase the risk of chronic low back pain and injury by increasing the exposure dose. In particular, there is data that helicopter pilots have more low back pain than fixed wing pilots. This is due to the fact that helicopters have much more vibration-generating factors due to the working principle of helicopters and the posture of helicopter pilots is slightly forward-leaning. In this study, an isolator cushion with a quasi-zero stiffness mechanism was developed, manufactured and tested to reduce the transmission of vibration to the pilot and flight crew during the operation of the Sikorsky UH-60 helicopter. The use of the specially designed cushion led to a noticeable reduction in vibration exposure under various flight conditions
