    We determined the antifungal and bioherbicidal properties of essential oils of Salvia absconditiflora. Its plant samples were collected from 10-locations in Kirsehir province, Turkey and dried in shade. Essential oils of dried plant samples were extracted by hydro-distillation method using a Schilcher device and the compounds identified in S. absconditiflora essential oils by GC-MS analysis were: Camphor (10.52-58.64%), Bicyclo [2.2.1] Heptane-2-One, 1.7.7 (21.94-30.16%) and viridiflorol (3.42-25.2%). S. absconditiflora essential oil (a dose of 10 mu l/petri dishes) inhibited the mycelium growth of Sclerotinia sclerotiorum and Alternaria solani pathogens by 9.3 and 54.40 %, respectively. At dose of 20 mu l/petri dish, the essential oil completely inhibited the mycelium growth of both pathogens. The S. absconditiflora essential oil at 20 mu l/petri dish. was 100 % phytotoxic to seed germination and seedling growth of Lepidum sativum and Amaranthus retroflexus. Thus S. absconditiflora essential oil can be used as an alternative to synthetic fungicide and herbicide to control the plant pathogenic fungi and weeds, respectively

    Get PDF
    Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014. Results: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosi) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto’s thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%. Conclusion: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan. © Journal of Clinical Research in Pediatric Endocrinology

    Background Disordered thyroid hormone transport, due to mutations in the SLC16A2 gene encoding monocarboxylate transporter 8 (MCT8), is characterised by intellectual and motor disability resulting from cerebral hypothyroidism and chronic peripheral thyrotoxicosis. We sought to systematically assess the phenotypic characteristics and natural history of patients with MCT8 deficiency. Methods We did an international, multicentre, cohort study, analysing retrospective data from Jan 1, 2003, to Dec 31, 2019, from patients with MCT8 deficiency followed up in 47 hospitals in 22 countries globally. The key inclusion criterion was genetically confirmed MCT8 deficiency. There were no exclusion criteria. Our primary objective was to analyse the overall survival of patients with MCT8 deficiency and document causes of death. We also compared survival between patients who did or did not attain full head control by age 1·5 years and between patients who were or were not underweight by age 1–3 years (defined as a bodyweight-for-age Z score <–2 SDs or <5th percentile according to WHO definition). Other objectives were to assess neurocognitive function and outcomes, and clinical parameters including anthropometric characteristics, biochemical markers, and neuroimaging findings. Findings Between Oct 14, 2014, and Jan 17, 2020, we enrolled 151 patients with 73 different MCT8 (SLC16A2) mutations. Median age at diagnosis was 24·0 months (IQR 12·0-60·0, range 0·0-744·0). 32 (21%) of 151 patients died; the main causes of mortality in these patients were pulmonary infection (six [19%]) and sudden death (six [19%]). Median overall survival was 35·0 years (95% CI 8·3–61·7). Individuals who did not attain head control by age 1·5 years had an increased risk of death compared with patients who did attain head control (hazard ratio [HR] 3·46, 95% CI 1·76–8·34; log-rank test p=0·0041). Patients who were underweight during age 1–3 years had an increased risk for death compared with patients who were of normal bodyweight at this age (HR 4·71, 95% CI 1·26–17·58, p=0·021). The few motor and cognitive abilities of patients did not improve with age, as evidenced by the absence of significant correlations between biological age and scores on the Gross Motor Function Measure-88 and Bayley Scales of Infant Development III. Tri-iodothyronine concentrations were above the age-specific upper limit in 96 (95%) of 101 patients and free thyroxine concentrations were below the age-specific lower limit in 94 (89%) of 106 patients. 59 (71%) of 83 patients were underweight. 25 (53%) of 47 patients had elevated systolic blood pressure above the 90th percentile, 34 (76%) of 45 patients had premature atrial contractions, and 20 (31%) of 64 had resting tachycardia. The most consistent MRI finding was a global delay in myelination, which occurred in 13 (100%) of 13 patients. Interpretation Our description of characteristics of MCT8 deficiency in a large patient cohort reveals poor survival with a high prevalence of treatable underlying risk factors, and provides knowledge that might inform clinical management and future evaluation of therapies

    This study was carried out to determine different forms of the effectiveness of oxalic and formic acid applied against Varroa destructor parasite, which is seen as the main cause of colony losses and low yield in honeybees (Apis mellifera L.) worldwide. Formic acid was tested in two trial groups (FormicPro™; 70% liquid formic acid) and oxalic acid in six trial groups (Dribbling; Spray; Sublimation; Glycerine Shop towel; sunflower Oil Shop Towel; Ultrasonic Fogging). The control group was not exposed to the application during the study. According to the results, the highest effect against varroa was determined in the FormicPro™ group (P<0.001). However, incubation activity of colonies almost completely ceases in formic acid groups. The rate of varroa infestation increased control group and the oxalic acid group treated with an ultrasonic fogging machine (P<0.001). In the autumn, it was concluded that not every application provided effective control against varroa at the location where the study was conducted. © 2022 The authors

    Sekonder Önlem Hastalarında Kardiyovasküler Riski Azaltmada PCSK9 İnhibitör Gereksinimine Özel Vurgu ile Lipit Modifikasyonu: Delphi Panel Yaklaşımına Dayalı Bir Analiz

    Objective: The aim of this study is to analyze the low-density lipoprotein cholesterol-lowering therapies in secondary prevention patients by analyzing their plasma low-density lipoprotein cholesterol levels, current treatment, considering their inadequate response to medications (as defined in current guidelines), and the requirement for a protein convertase subtilisin/kexin type 9 inhibitor. Methods: Delphi panel is used to seek expert consensus of experienced 12 cardiologists. A questionnaire consisting of 6 main questions is used to reflect the opinion of the expert panelists on the practices of low-density lipoprotein cholesterol-lowering therapies of patients with high and very high cardiovascular risk. Patients with atherosclerotic cardiovascular disease are covered in this present analysis. Results: According to expert opinion data, 18.6% of the patient population with atherosclerotic cardiovascular disease is estimated to have experienced recurrent vascular events. The current treatment of the patient population is 39.7% on high dose, 36.9% on low/moderate dose of statin, 13.1% on maximum tolerated dose statin + ezetimibe, and 1.2% on maximum tolerated dose statin + ezetimibe + protein convertase subtilisin/kexin type 9 inhibitor. The percentage of atherosclerotic cardiovascular disease patients with inadequate treatment response is estimated to be 20.2% in those using “maximum tolerated dose statin + ezetimibe.” The proportion of patients who will need to be treated with a protein convertase subtilisin/kexin type 9 inhibitor increases as their low-density lipoprotein cholesterol levels rises from 9.1% in 70-99 mg/dL to 50.8% in ?160 mg/dL for these patients. Conclusion: According to expert opinion, although a substantial proportion of patients with secondary prevention have not achieved low-density lipoprotein cholesterol goals, the use of protein convertase subtilisin/kexin type 9 inhibitors is very low. Since the questionnaire subject to panel discussion did not include any question elaborating the issue, the discrepancy between the recommendation of the related guidelines and Turkish practice needs further studies for the explanation. © 2022 Turkish Society of Cardiology.

    PubMedID: 30132287Background: Studies regarding genetic and clinical characteristics, gender preference, and gonadal malignancy rates for steroid 5-alpha-reductase type 2 deficiency (5?-RD2) are limited and they were conducted on small number of patients. Objective: To present genotype–phenotype correlation, gonadal malignancy risk, gender preference, and diagnostic sensitivity of serum testosterone/dihydrotestosterone (T/DHT) ratio in patients with 5?-RD2. Materials and methods: Patients with variations in the SRD5A2 gene were included in the study. Demographic characteristics, phenotype, gender assignment, hormonal tests, molecular genetic data, and presence of gonadal malignancy were evaluated. Results: A total of 85 patients were included in the study. Abnormality of the external genitalia was the most dominant phenotype (92.9%). Gender assignment was male in 58.8% and female in 29.4% of the patients, while it was uncertain for 11.8%. Fourteen patients underwent bilateral gonadectomy, and no gonadal malignancy was detected. The most frequent pathogenic variants were p.Ala65Pro (30.6%), p.Leu55Gln (16.5%), and p.Gly196Ser (15.3%). The p.Ala65Pro and p.Leu55Gln showed more undervirilization than the p.Gly196Ser. The diagnostic sensitivity of stimulated T/DHT ratio was higher than baseline serum T/DHT ratio, even in pubertal patients. The cut-off values yielding the best sensitivity for stimulated T/DHT ratio were ? 8.5 for minipuberty, ? 10 for prepuberty, and ? 17 for puberty. Conclusion: There is no significant genotype–phenotype correlation in 5?-RD2. Gonadal malignancy risk seems to be low. If genetic analysis is not available at the time of diagnosis, stimulated T/DHT ratio can be useful, especially if different cut-off values are utilized in accordance with the pubertal status. © 2018, Italian Society of Endocrinology (SIE).32015Funding This work was supported financially by the Turkish Pediatric Endocrinology and Diabetes Society (Grant number: 032015)
