    Cimbex quadrimaculatus (Hymenoptera: Cimbicidae) is one of the serious pests of almonds in Turkey and worldwide. Since there is no effective control application against this pest, it has been a serious problem up to now. Therefore, we aimed to find an effective bacterium that can be utilized as a biocontrol agent against C. quadrimaculatus in pest management. We isolated seven bacteria from dead and live C. quadrimaculatus larvae, and evaluated the larvicidal potency of all isolates on the respective pest. Based on the morphological, physiological, biochemical and molecular properties (partial sequence of 16S rRNA gene), the isolates were identified to be Bacillus safensis (CQ1), Bacillus subtilis (CQ2), Bacillus tequilensis (CQ3), Enterobacter sp. (CQ4), Kurthia gibsonii (CQ5), Staphylococcus sp. (CQ6) and Staphylococcus sciuri (CQ7). The results of the larvicidal activities of these isolates indicated that the mortality value obtained from all treatments changed from 58 to 100 %, and reached 100 % with B. safensis (CQ1) and B. subtilis (CQ2) on the 3rd instar larvae within 10 days of application of 1.89 x 10(9) cfu/mL bacterial concentration at 25 A degrees C under laboratory conditions. Findings from this study indicate that these isolates appear to be a promising biocontrol agent for C. quadrimaculatus.

    Metabolic Dysfunction-Associated Fatty Liver Disease and Fibrosis Status in Patients with Type 2 Diabetes Treated at Internal Medicine Clinics: Türkiye DAHUDER Awareness of Fatty Liver Disease (TR-DAFLD) Study
    (Aves, 2024) Sahinturk, Yasin; Koker, Gokhan; Koca, Nizameddin; Sumbul, Hilmi Erdem; Demir, Ismail; Keskin, Havva; Yaylaci, Selcuk
    Background/Aims: This awareness study aimed to determine the ultrasound (US) examination rates in relation to US-confirmed metabolic dysfunction-associated fatty liver disease (MAFLD) diagnosis in internal medicine outpatients with type 2 diabetes (T2D) across T & uuml;rkiye. Materials and Methods: A total of 6283 T2D patients were included in this multicenter retrospective cohort study conducted at 17 internal medicine clinics across T & uuml;rkiye. The presence and indications for US performed within the last 3 years were recorded along with US-confirmed MAFLD rates, laboratory findings on the day of US, and referral rates. Fibrosis-4 (FIB-4) index was calculated to estimate the risk of advanced liver fibrosis (FIB-4 index >= 1.3). Results: Overall, 1731 (27.6%) of 6283 patients had US examination, which revealed MAFLD diagnosis in 69.9% of cases. In addition, 24.4% of patients with US-confirmed MAFLD were at risk of advanced fibrosis (FIB-4 index >= 1.3), and the referral rate was 15.5%. Conclusion: In conclusion, our findings emphasize an insufficient MAFLD awareness among clinicians and the likelihood of most of T2D patients to be at risk of living with an unknown status regarding their MAFLD and advanced fibrosis risk.
