Spat recruitment of endangered Bivalve Pinna nobilis (Linnaeus, 1758) at two different depths in Izmir Bay, Turkey

WOS: 000455002200001Spat recruitment of a large bivalve species endemic to the Mediterranean Sea and naturally found at Izmir, Turkey (Urla, Karantina Island), the fan mussel Pinna nobilis (Linnaeus, 1758), has been researched. The study was carried out between May and October 2012. The aim of this study was to determine the spat recruitment of the fan mussel. Collector systems were prepared with onion bags and pvc pipes. Collectors were deployed at two different depths (1 m and 8 m). Every month a new collector system was deployed at the study site and previous collectors were recovered. Length and weight of attached spats were recorded. Water temperature, salinity, chlorophyll-a and particulate matter were measured monthly. Surface collectors gathered 60.6 % of total spats. It was observed that, June, July and August were the most appropriate months to deploy fan mussel spat collectors for this site. Our results also showed that the main recruitment period of Pinna nobilis spat at the study site was between July and September.Scientific Research Projects Council of Ege University [13/SUF/005]This research was supported by a project numbered 13/SUF/005 by the Scientific Research Projects Council of Ege University

İzmir (Özbek-Urla) Kıyılarında Yassı İstiridye (Ostrea edulis L. 1758) Büyütme Çalışması

Bu çalışmada Özbek-Urla (İzmir)’de dağılım gösteren Avrupa istiridyesinin (Ostrea edulis L. 1758) büyüme ve yaşama oranlarını belirlemek amacıyla büyütme sistemlerine yerleştirilmiş spatlar incelenmiştir. Yıl boyunca su parametrelerinden sıcaklık, tuzluluk, toplam partikül madde (TPM) (partikül organik-POM ve partikül inorganik-PIM) ve klorofil-a değerleri kaydedilmiştir. Toplam partikül madde en yüksek haziran ayında 34,62 mg/l bulunmuştur. Haziran ayında partikül madde içerisindeki inorganik madde oranı %77,61, organik madde oranı ise %22,39 olarak tespit edilmiştir. Büyütme sistemlerine alınan istiridye yavruları boy ortalamaları çalışmanın başlangıcında 26,39±4,00 mm’den çalışmanın sonunda 60,84 ±10,71 mm’ye ulaşmıştır. İstiridyelerin yaşama oranı % 61,9 olarak bulunmuştur. Yaşama oranı ile Sıcaklık ve PİM arasında anlamlı negatif korelasyon (sırasıyla r2 =-0,654, r2 =-0,644) bulunmuştur (p<0,05). Elde edilen yaşama ve büyüme oranı sonuçları, bu bölgenin Ostrea edulis yetiştiriciliği için uygun olabileceğini göstermektedir

This study examined fecundity, by means of the gonad index of the most common and abundant echinoderm species (Paracentrotus lividus) of the Aegean Sea (western Turkey). Paracentrotus lividus samples were collected monthly at the coast of Cesme for six months and biometric parameters were measured and then the animals’ dissected. Gonad indices were calculated. The mean fecundity (number of eggs) was determined and eggs diameter were measured. Mean egg diameter was 91.14±1.46 µm. There was a peak in fecundity in March (346.582 eggs/female) that correlated with the observed peak in GSI (11.02±0.54 %) and egg size (95.68±01.98 µm). The results presented here show that a significant different was found in egg numbers and egg sizes between months (p&lt;0.05)

Çeşme Körfezi’ndeki Avrupa Deniz Kestanesi gonadının (Paracentrotus lividus, Lamarck 1816) kalitatif ve kantitatif incelenmesi

Bu çalışmada, Ege Denizi'nde (Türkiye'nin batısı) yaygın bulunan echinoderm türlerinden Paracentrotus lividus'un fekondite ve gonad indeksi özetlenmiştir. Çeşme kıyısal alandan aylık olarak Paracentrotus lividus toplanarak biyometrik ölçümleri yapıldıktan sonra kesme işlemi gerçekleştirilmiştir. Gonad indeksleri hesaplanmıştır. Ortalama fekondite (yumurta sayısı) belirlendi ve yumurta çapı ölçülmüştür. Ortalama yumurta çapı 91.14±1.46 µm. Fekondite Mart ayında pik yaptı (346.582 eggs/female) ve ilişkili olarak gonad indeksi (11.02±0.54 %) ve yumurta boyu da (95.68±01.98 µm) bu ayda en yüksekti. Buradaki sonuçlar, aylara göre yumurta sayısı ve yumurta boyunda önemli bir farklılık (p0.05) olduğunu göstermiştirThis study examined fecundity, by means of the gonad index of the most common and abundant echinoderm species (Paracentrotus lividus) of the Aegean Sea (western Turkey).

Effect of intraoperative esmolol infusion on anesthetic, analgesic requirements and postoperative nausea-vomitting in a group of laparoscopic cholecystectomy patients

PURPOSE: Postoperative pain and nausea/vomitting (PNV) are common in laparoscopic cholecystectomy patients. Sympatholytic agents might decrease requirements for intravenous or inhalation anesthetics and opioids. In this study we aimed to analyze effects of esmolol on intraoperative anesthetic-postoperative analgesic requirements, postoperative pain and PNV. METHODS: Sixty patients have been included. Propofol, remifentanil and vecuronium were used for induction. Study groups were as follows; I - Esmolol infusion was added to maintenance anesthetics (propofol and remifentanil), II - Only propofol and remifentanil was used during maintenance, III - Esmolol infusion was added to maintenance anesthetics (desflurane and remifentanil), IV - Only desflurane and remifentanil was used during maintenance. They have been followed up for 24 h for PNV and analgesic requirements. Visual analog scale (VAS) scores for pain was also been evaluated. RESULTS: VAS scores were significantly lowest in group I (p = 0.001-0.028). PNV incidence was significantly lowest in group I (p = 0.026). PNV incidence was also lower in group III compared to group IV (p = 0.032). Analgesic requirements were significantly lower in group I and was lower in group III compared to group IV (p = 0.005). Heart rates were significantly lower in esmolol groups (group I and III) compared to their controls (p = 0.001) however blood pressures were similar in all groups (p = 0.594). Comparison of esmolol groups with controls revealed that there is a significant decrease in anesthetic and opioid requirements (p = 0.024-0.03). CONCLUSION: Using esmolol during anesthetic maintenance significantly decreases anesthetic-analgesic requirements, postoperative pain and PNV

Seizure due to multiple drugs intoxication: a case report

The mechanism of the antidepressant effect of bupropion is not fully understood. Besides, using it in the treatment of depression, it is found to be effective in reducing withdrawal symptoms due to smoking cessation. A 28-year-old female patient with a history of depression was admitted to emergency department an hour after ingestion of bupropion, quetiapine, and levothyroxine in high doses to commit suicide. While accepting her into the Intensive Care Unit, she was awake, alert, disoriented and agitated. After 2 h, the patient had a generalized tonic–clonic seizure. The necessary treatment was given and 9 h later with hemodynamic improvement, the patients’ mental status improved.Bupropion may cause unusual behaviors such as delusions, paranoia, hallucinations, or confusion. The risk of seizure is strongly dose-dependent. We want to emphasize the importance of early gastric lavage and administration of activated charcoal. Resumo: O mecanismo do efeito antidepressivo de bupropiona ainda não está bem esclarecido. Contudo, seu uso no tratamento de depressão revelou ser eficaz para reduzir os sintomas de abstinência relacionados à cessação do tabagismo. Uma paciente do sexo feminino, 28 anos, com história de depressão, deu entrada no setor de emergência uma hora após a ingestão de bupropiona, quetiapina e levotiroxina em doses elevadas para cometer suicídio. Ao ser internada em unidade de terapia intensiva, estava acordada, alerta, desorientada e agitada. Após duas horas, apresentou uma crise tônico-clônica generalizada. O tratamento necessário foi administrado e nove horas mais tarde, com a estabilização hemodinâmica, o estado mental da paciente melhorou.Bupropiona pode causar comportamentos incomuns, incluindo delírios, paranoia, alucinações ou confusão mental. O risco de convulsão é altamente dependente da dose. Queremos enfatizar a importância da lavagem gástrica precoce e da administração de carvão ativado.
