الوصف: Background The codling moth (CM), Cydia pomonella (L). (Lepidoptera: Tortricidae), is an important pest of apple in Turkey and other apple producing countries in the world. Several control methods are available for reducing the pest populations. Entomopathogenic nematode (EPNs), for example, can be used as a potential alternative to chemical insecticides to control codling moth larvae in the soil as eco-friendly management their hosts that can actively find them in cryptic locations. Results Efficacy of 4 EPN isolates, Steinernema carpocapsae (Bakışlı), S. feltiae (ES-3), Heterorhabditis bacteriophora (TOK-20) and H. bacteriophora (11-KG) for controlling the 1st instar larvae of the codling moth ( Cydia pomonella L.) was investigated under controlled laboratory conditions. Codling moth was susceptible to different rates to all the 4 EPN isolates. All nematode trials were more effective than the control (water). The overall mortality caused by S. carpocapsae (Bakışlı 05) was significantly higher than the other EPN species. S. carpocapsae was the most effective with the highest tested concentration (100 IJs/larva), killing 82.63% of codling moth larvae, followed by S. feltilae (ES-3), with a mortality rate of 71.5%. H. bacteriophora (TOK-20) exhibited the least mortality at 25 IJs/larva concentration in all experiments. Conclusion The study proved that these nematodes were very efficient and could be used to control codling moth in biological control programs.

الوصف: The spotted-wing drosophila (SWD), Drosophila suzukii, is a polyphagous invasive pest species native to Asia that is able to attack a wide variety of small-fruit crops. This fly is able to lay eggs in fresh ripening fruits due to the serrated ovipositor of the female. The insertion of the ovipositor produces physical damage to the host fruits, and the feeding larvae cause soft and rot fruits. Resulting damage can be up to 80% crop loss. In this context, the development of IPM programs for the control of D. suzukii is of great importance to reduce the huge economic impact that this fly can potentially exert on European agriculture. The main objectives of the project were: to improve the basic knowledge about the biology of the fly, including the effect of temperature on development, reproduction and population increase and the overwintering behaviour; to develop effective trapping systems for population reduction; to evaluate alternative methods for control, such as insect growth regulators and entomopathogenic microorganisms; and to perform monitoring surveys for early detection and to develop quarantine measures and effective surveys of goods in global trade among countries. ; Report of the Euphresco project 'IPM Strategies against Drosophila suzukii (IPMDROS)'

Winter 2017; 11(1):37-42. AbstractObjectiveThe morphology of anterior cerebral artery (ACA) in patients with hydrocephalus (HCP) was analyzed, and its importance was discussed in maintaining cerebral perfusion.Materials & MethodsA total of 84 cases in 2 groups between 0 and 3 months, followed-up at Firat Universitesi Hastanesi, Beyin Cerrahisi Klinigi, Elazig, Turkiye due to in 2010-2013, were enrolled. Two groups were created for the study. Group 1; patients with HCP and Group 2; as control group without HCP. In both groups, the length of the A2 segment of ACA was measured from its origin to the junction of the genu and body portions of the corpus callosum on T2 mid-sagittal magnetic resonance (MR) scans. For all cases, axial MR imaging scans were used to calculate Evans’ index (EI), and the cases were divided into three groups: Group A, EI ≥50%; Group B, EI of 40-50% and Group C, EI <40%. The two groups (Groups 1 and 2) were compared with respect to ACA length, and the correlation with the EI was quantified. P values below 0.05 were considered statistically significant.ResultsMean length of ACA was 57.3 mm in Group 1 and 37.5 mm in Group 2. EI increased as the length of ACA increased. A statistical comparison of the two groups revealed that the ACA length was significantly greater in Group 1. The relationship between EI and ACA length was statistically significant.ConclusionReducing ventricular size appears to be an important factor in addition to reducing intracranial pressure in an attempt to maintain normal cerebral perfusion(CP).References1.

مصطلحات موضوعية: Intervertebral Disc Degeneration, Intervertebral Disc Displacement, Matrix Metalloproteinase 11, Middle Age

الوصف: WOS: 000372668700017 ; PubMed ID: 26956825 ; AIM: The intervertebral disc starts to degenerate when a human being begins to stand and learn to walk. It is known that many extrinsic, intrinsic and genetic factors play a role in disc degeneration. In this study, we examined whether the matrix metalloproteinase 11 might be associated with intervertebral disc degeneration. MATERIAL and METHODS: Fifty-six patients with lumbar disc herniations who were operated at Gortepe Education and Research Hospital, Neurosurgery Clinic between September 2008 and December 2009 were prospectively reviewed. History and complaints were obtained from the case reports. Neuroradiological evaluation was performed with magnetic resonance imaging. Surgical findings of cases were reported in the operation notes. Microscopic posterior hemipartial laminectomy and discectomy were performed in all cases. Degenerated herniated disc material of all cases extracted during surgery was evaluated with immunohistochemical staining in Marmara University, Institute of Neurological Sciences, Pathology Laboratory. RESULTS: Comparing the immunohistochemical staining of cases who were 50 years or younger and cases who were over 50 years old, statistical significance was determined. CONCLUSION: Matrix metalloproteinase 11 has a role in degenerating intervertebral disc disease, but it is not the only factor. Matrix metalloproteinase 11 might be a genetic factor in young-middle aged patients.

مصطلحات موضوعية: Children, Hydrocephalus, Shunt revision

الوصف: Abdominal pseudocyst is a rare complication developing after ventriculoperitoneal shunt treatment. It is more commonly seen particularly in children. The underlying pathogenesis may be associated with repeat revisions or infections. Morphologically, it has no complete cyst wall, presenting only with a pseudocapsule among the intestinal loops, around the lower shunt tip. The principal problem appears to be the reduced peritoneal absorption capacity. The treatment is complicated and difficult. In this report, we present an 8-year-old abdominal pseudocyst case with a history of many shunt revisions.

الوصف: WHO sınıflaması tümörlerin histolojik özellikleri değerlendirilerek yapılan bir sınıflama olup, onların biyolojik davranışlarının anlaşılmasında yetersiz kalmaktadır. Son zamanlarda tümörlerin biyolojik davranışlarını gösteren ekstrasellüler matriks komponentleri ile ilgili çalışmaların sayısı artmaktadır. MMP-11; MMP ailesi üyesi olan bir metalloproteinaz olup diğer aile üyelerinden etki mekanizması,subtrat yelpazesi,ve ekspresyon paterni bakımından farklılık gösterir. Çalışmamızda; 55 benign meningioma olgusu incelendi.Bunların 29' u transisyonel,16' sı meningotelyamatöz,8' i fibroblastik alttipte idi. Meningotelyamatöz olanlarda MMP-11 ekspresyon katsayısının yüksek(), fibroblastik olanlarda düşük (.5) olduğu tespit edildi. Ki-67 düzeyi MMP-11 ekspresyon katsayısı yüksek olgularda anlamlı derecede yüksek iken diğerlerinde düşük bulundu. Rekurrens gösteren olgularda istatistiksel olarak anlamlı sonuç çıkmasa da, rekurrens gösteren 7 olgunun 5'inde MMP-11 ekpresyon katsayısı yüksekti. Bu çalımaya göre Grade I meningiomalarda MMP-11 eksprese edilmektedir. MMP-11 ekpresyonu meningotelyamatöz tümörlerde daha yüksek iken fibroblastiklerde düşüktür. MMP-11 ekspresyonu yüksek tümörlerde Ki-67 ekspresyonu da yüksektir. ; The WHO categorises tumours based on their histological properties; however, this classification falls short of understanding their biological behaviours. Recently, there has been an increase in the number of studies on extracellular matrix components with the aim of understanding the biological behaviours of tumours. MMP-11 is a metalloproteinase from the MMP family that has a different expression pattern, mechanism of action, and substrate range compared with the other members of this family. Of the 55 benign meningioma cases examined, 29 were transitional, 16 were meningothelial, and 8 were fibroblastic in nature. In the meningotheliomatous cases, the MMP-11 expression score was high (75%), whereas it was low in the fibrous cases (87.5%). The Ki-67 levels in the cases with high MMP-11 expression ...

الوصف: Nocardial brain abscesses remain a clinical challenge. We successfully treated a patient with nocardial brain abscess, mycetoma, pneumonia, and glomerulonephritis. Nocardial soft tissue involvement, mycetoma, is well known. However, the fact that actinomycetoma can metastasize may not be as well appreciated. The association between nocardiosis and glomerulonephritis should be better clarified.

الوصف: AIM: To analyse the effect of MMP-3 (Matrix Metalloproteinase Enzyme-3)-one of the extracellular matrix proteins-on the prognosis and biological behaviour of meningiomas. MATERIAL and METHODS: 79 cases of meningioma that were operated in our clinic between 2005 and 2010 were retrospectively analysed. Age, sex, preoperative peritumoral edema, histological subtype, grade, Ki-67 expression, MMP-3 staining pattern and recurrence rate were analysed. Pathological preparations were graded according to the WHO (World Health Organisation) 2007 grading system. RESULTS: Of the MMP-III positive cases; 24 cases (60%) were grade I, 16 cases were grade II. The MMP-3 staining pattern was significantly positive (80%) in grade II meningioma. 14 of the MMP-3 positive cases were atypical meningiomas. Of the 20 cases with high Ki-67 proliferation index (PI), 12 cases (60%) were MMP-3 positive and 8 cases (40%) were MMP-3 negative. Rates of recurrence and preoperative peritumoral edema were high in cases with MMP-3 positivity. CONCLUSION: In this study it was determined that MMP-3 positivity has a strong relationship with meningiomas having an aggressive character. MMP-3 may be used as a proliferation marker for biological behaviour, recurrence rate and prognosis of meningiomas.
