Femoral nerve compression secondary to a ganglion cyst arising from a hip joint: a case report and review of the literature
<p>Abstract</p> <p>Introduction</p> <p>Femoral nerve compression due to a cystic lesion around the hip joint is rare and only a few cases have been described in the literature. Among these, true ganglion cysts are even more rare.</p> <p>Case presentation</p> <p>We report the case of a 57-year-old woman with femoral nerve compression caused by a true ganglion cyst of the hip joint.</p> <p>Conclusion</p> <p>A high index of suspicion is required to predict a non-palpable cystic lesion around the hip joint as it may mimic different disorders and should be kept in mind in the differential diagnosis of unusual groin pain, radicular pain and peripheral vascular disorders.</p

Effects of Several Cultivars', Mulch and Fertilizer Applications on Plant Growth and Development Criteria and Plant's Nutrition Elements Uptake in Organic Strawberry Plantation in Nevsehir City
This study was conducted to investigate the effect of different mulch types’ (black plastic, textile and sawdust) and fertilizer applications (Ekoflora, Mog, Bio-one, Ferbanat L and Natural Bioplasma) effect in strawberry (Fragaria vesca L.) cultivars (‘Monterey’, ‘Albion’, ‘Aromas’, ‘Camarosa’ and ‘Sweet Charlie’). The effects of applications on plant nutrient concentrations (N, P, K, Ca, Mg and Fe) and plant growth and development criteria (plant height, steam diameter, number of leaf and root height) were determined. Fertilizer material and cultivars caused significant differences in the plant growth and development of five strawberry cultivars, while mulch materials’ effects found only on number of leaf and root height. Highest values in terms of plant growth and development criteria were found in ‘Camarosa’ cultivar and black plastic and textile mulch. The most superior cultivar in terms of plant's nutrition elements uptake was ‘Camarosa’. Black plastic and textile mulch were found more advantageous compared to sawdust mulch. Differences in the plant growth and development criteria and plant's nutrition elements uptake obtained from fertilizer applications were noted
The etiopathogenetic factors which figure in the development of polycystic ovary syndrome
Amaç: Polikistik Over Sendromunun farklı kriterlere göre tanımlanması ve bu sendromun gelişiminde rol alan etyopatogenetik faktörlerdeki çeşitliliğin araştırılmasıdır. Method: Polikistik Over Sendromu ilk olarak 1935'de Stein ve Leventhal tarafından tanımlanmıştır. Geçmiş yıllarda klinik tanı amenore, hirsutizm, obesite triadından oluşmaktaydı. Ancak son zamanlarda yapılan çalışmalar ise PKOS'nun geniş, heterojen bir klinik tabloya ve multifaktöriyel bir etyolojiye sahip olduğunu göstermiştir. PKOS'da görülen hiperandrojenizm ve anovulasyon endokrinolojik olarak 4 kompartmanda görülen anormallikler sonucu ortaya çıkar; over, adrenal bez, cilt ve yağ dokusu, hipotalamo-hipofizer aks. PKOS'nda etyopatogenez.de hipotalamo-ptuiter-overyen akstaki değişiklikler, intrinsik over patolojisi, peripubertal ekzajere adrenarş ve fizyolojik insülin rezistansının birlikteliği, obezite, patolojik insülin rezistansı ve pankreasla beta hücre disfonksiyonu ve genetik etyolojiye işaret eden ailesel birikimin rolü kesin olarak gösterilmekle beraber bu konuda halen çalışmalar devam etmektedir. Bu derlemede 'PKOS'nun farklı kriterlere göre tanımlanması ve sendromun gelişiminde rol alan çeşitli etyopatogenetik faktörler anlatılmaktadır. Sonuç: PKOS'da etyopatogenetik faktörlerin tam olarak bilinmesi; hastalığın tanısı, izlemi, tedavisi ve uzun dönem komplikasyonların gelişiminin engellenmesi açısından çok büyük bir önem kazanmaktadır.Objective: To define the polycystic ovary syndrome according to different criteria and to investigate the diversity of the etiopathogenetic factors which figure in the development of polycystic ovary syndrome. Method: Polycystic ovary syndrome was first described by Stein and Leventhal in 1935. The clinical diagnosis was based on the triad of amenorrhea, hirsutism and obesity in past years. On the other hand recent studies have shown that PCOS has an extensive, heterogen clinical view and multifactorial etiology. Hyperandrogenism and anovulation seen in PCOS are arised endocrinogically as a consequence of the anomalies of 4 compartments: over, adrenal gland, skin and fat tissue, hypothalamic-pituitary axis. However the alterations of hypothalamic-pituitary-ovarian axis, intrinsic ovary pathology, synergy of peripubertal exagere ad-renarge and physiological insulin resistance, obesity, pathologic insulin resistance and beta cell disfunction of pancreas and the role of familial aggregation indicating the genetic etiology have been definitely revealed in the etiopatho genesis of PCOS, studies are currently carried on this subject. In this review the definition of PCOS according to different criteria and the variable etiopatho genetic factors that figure in the development of this syndrome are explained. Conclusion: Assuming the etiopatho genetic factors entirely become very important for the diagnosis, trial, treatment of the disease and also for the prevention of complications
Switchless bidirectional amplifier for wireless communication systems
A bidirectional amplifier working at 2.4 GHz is presented in this article. The presented amplifier is able to amplify two signals simultaneously. This, since commonly used radio frequency switches are replaced by circulators. The amplifier is designed on a single small-sized printed circuit board. First, the new amplifier circuit is proposed and characterized. Then, its advantages and design problems are analyzed. Finally, design instructions are setup in order to obtain a good performance of the switchless amplifier within the frequency band of interest.TÜBİTA
