A comparative study about antioxidant activity and phenolic composition of cumin (Cuminum cyminum L.) and coriander (Coriandrum sativum L.)

383-393Apiaceae (Umbelliferae) is a large family which involves approximately 455 genus and 3600 species. Coriander (C. sativum L.) and cumin (C. cyminum L.) are two members of Apiaceae family which commonly used for medicinal purpose due to their antioxidant activity. Since the antioxidants are compounds that prevent the oxidation by neutralizing free radicals, researches about their potential utilizations are of great interest for food science and technology. Due to the consumer preference and the worries about synthetic antioxidant compounds, the food industry shows tendency to use natural antioxidant compounds obtained from plant materials. FDA has recognized more than 150 plants as GRAS, without no limitations intake. Coriander, cumin, anise, fennel, thyme and oregano are some plants found in this list. The focus of this research is to contrast the composition of phenolic profile and antioxidant activity of ethanolic and methanolic extracts of these two medicinal herbs belonging to the Apiaceae family. For this purpose, coriander and cumin were analyzed for phenolic compounds and antioxidant assay. Antioxidant assay analyses were performed by applying cupric reducing antioxidant capacity (CUPRAC), 2,2'-azino-bis3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), 1,1-diphenyl-2-picrylhydrazyl methods (DPPH)

Redcell Distribution Width, Mean Platelet Volume, Platelet Distribution Width Parameters and Disease Severity Relationship in Patients with Obstructive Sleep Apnea Syndrome

Objective: To evaluate the relationship between redcell distrubution width (RDW), platelet distribution width (PDW), mean platelet volume (MPV) parameters and the disease severity in Obstructive sleep apnea syndrome (OSAS) patients; to benefit from the biomarkers to take early measures on disease treatment, follow-up and complications (as thromboembolic events and cardiovascular diseases). Materials and Methods: Our study is a retrospective and a cross-sectional study and we planned to asses polysomnography (PSG) records of the patients. Patients who were diagnosed with OSAS by PSG were grouped as 108 mild patients with [Respiratory Disturbance Index (RDI): 5-14.9]; 69 moderate patients (RDI: 15-30); 66 severe patients (RDI>30) and 117 patients were control group (RDI<5). The age range was between 18 and 78. Inclusion criterions were routine blood count, RDW, MPV and PDW. Results: Three hundred and sixty patients were enrolled in the study. 74.2% of them were male; mean age was 46.5. The average patient O2 saturation was 93.2. When moderate OSAS group was compared with the control group, hematocrit (Htc) (p=0.004) and hemoglobin (Hb) (p=0.002) were found to be significantly increased. When severe OSAS group was compared with the control group, MPV (p=0.017) was decreased significantly, Htc (p=0.006) and Hb (p=0.02) were found to be significantly increased. Conclusion: In our study, when the other groups and the control group were compared, we observed significantly increased Hb and Htc values in moderate and severe OSAS groups, however some other studies gives an increase in MPV we observed a decrease in severe group. Having few number of patients in moderate and severe OSAS groups may have led to such results. Therefore, more extensive and prospective studies are needed

Current conduction in Schottky barrier diodes with poly(propylene glycol)-b-polystyrene block copolymer interfacial layer

Polymeric materials have gained great importance in electron devices. There has been considerable number of studies on block copolymers due to enhanced features that appear after co-polymerization. In this study, poly (propylene glycol)-b-polystyrene block copolymer has been synthesized and Schottky barrier diodes (SBDs) have been fabricated with this block copolymer. Current-voltage (I-V) measurements have been conducted at room temperature in order to investigate electrical characteristics and current conductions governing in these SBDs. Series resistance and shunt resistance of the SBDs have been calculated using Ohm’s law. Ideality factor, reverse saturation current and zero-bias barrier height of the SBDs have been extracted from the forward-bias I-V data. Fabricated SBDs exhibited high rectifying ratio of the order 104. Also, current conduction mechanisms and the density of interface states in the SBDs have been investigated. Calculated values of density of interface states in the SBDs are on the order of 1013 which is acceptable for this kind of SBDs having polymeric interfacial layer

A Rare Dermatologic Disease in Pregnancy: Rosacea Fulminans- Case Report and Review of the Literature

BACKGROUND: Rosacea is a common, chronic disorder that can present with a variety of cutaneous or ocular manifestations. Skin involvement primarily affects the central face, with findings such as persistent centrofacial redness, papules, pustules, flushing, telangiectasia, and phymatous skin changes. The pathways that lead to the development of rosacea are not well understood. The relationship of pyoderma faciale (also known as rosacea fulminans) to rosacea also is uncertain. We aimed to write this article with the aim of showing how a pregnant patient who has been aggravated by the degree of lesions on the face during the first trimester of pregnancy is treated and to show what is in the literature in this issue.CASE REPORT: A 22-year-old woman complained of painful erythema, papules and pustules on the face. She had fever and malaise during the sixth week of her first pregnancy and a history of the mild eruption and seborrhea before her pregnancy with flaring over the preceding 4 weeks. Dermatologic examination revealed red erythema of all involved facial areas; the lesions consisted of papules, pustules and nodules. The case was diagnosed as rosacea fulminans (pyoderma faciale) by these findings. In the literature, there are some effective therapeutic options such as retinoids, tetracyclines, antiandrogenic contraceptives, and dapsone and these were not used because they are contraindicated in pregnancy. Amoxicillin-clavulanic acid 1 gr/day, wet compresses, and a fusidic acid cream were started. After the activity of the disease had been suppressed for 10 days, antibiotic was stopped, and the other treatment options were applied topically for the next month. One month after cessation of treatment, the lesions had disappeared with only mild erythema remaining. There was minimally flushing on the face and no telangiectasia.CONCLUSION: In conclusion, there is no substantial evidence as to the mechanism by which pregnancy may trigger this conditioner whether the gender of the fetus influences the development of rosacea fulminans, but is generally accepted that hormonal changes in pregnancy play an important role. The pathogenesis of rosacea fulminans remains uncertain, but it is obvious that the further basic and clinical research is required to optimise the management of this rare facial dermatosis

Farklı Primerlerin ve Universal Adezivin, Zirkonya ve Self Adeziv Rezin Siman Arasındaki Makaslama Bağlanma Dayanımı Üzerine Etkisi

Amaç: Bu çalışmanın amacı, alüminyum oksit partikülleriyle kumlama sonrası kullanılan farklı primerlerin ve universal adezivin, termal yaşlandırma sonrasında zirkonya ile self adeziv rezin siman arasındaki makaslama bağlanma dayanımı üzerindeki etkisini değerlendirmektir. Gereç ve Yöntem: Çalışmamızda CAD/CAM zirkonya bloklardan boyutları 2 mm x 11 mm x 11 mm olacak şekilde 20 adet dörtgen örnek hazırlanmıştır. Tüm örneklerin yüzeyine 50 µm Al2O3 partikülleri yüzey pürüzlendirme işlemi uygulanmıştır. Hazırlanan örnekler farklı primer ve adeziv uygulamalarına göre 4 alt gruba ayrılmıştır (n=5). Kontrol: Herhangi bir primer veya universal adeziv uygulanmamıştır. Kerr Silane Primer (Negatif Kontrol): MDP içeriği bulunmayan seramik primeri uygulanmıştır. Ceramica-S ve Nova Compo-B Plus: Ceramica-S primer ve Nova Compo-B Plus universal adeziv karıştırılarak uygulanmıştır. Clearfil Ceramic Primer Plus: Clearfil Ceramic Primer Plus uygulanmıştır. Yüzey uygulamalarını takiben self adeziv rezin siman seramik yüzeylerine polimerize edilmiştir. Ardından örnekler 5000 devir termal döngü işlemine tabi tutulmuştur. Örneklere universal test cihazında makaslama bağlanma dayanımı testi uygulanmıştır. Yüzey işlemlerine göre Fmax (N) ve Mpa değerlerinin karşılaştırılmasında Tek Yönlü Varyans Analizi kullanılmıştır. Bulgular: Farklı primer ve adeziv kullanımına göre Fmax (N) ortalama değerleri istatistiksel olarak anlamlı bir farklılık göstermiştir (p&lt;0,001. Ceramica S ve Nova Compo-B Plus ile elde edilen değer diğer tüm primer gruplarından farklılık göstermiştir ve daha yüksektir (p&lt;0,001). Clearfil Ceramic Primer Plus ile elde edilen değer de diğer gruplardan farklılık göstermiştir (p&lt;0,001). Kontrol grubu ve Kerr Silane Primer gruplarında elde edilen Fmax (N) değerleri benzerlik göstermektedir (p&gt;0,001). Sonuç: Mevcut limitasyonlar dahilinde, self adeziv rezin simanın herhangi bir primer uygulaması olmaksızın veya MDP içermeyen bir primer uygulanmasının, zirkonya seramik yüzeyine bağlanma gücünü artırmak için yeterli olmadığı sonucuna varılabilir. MDP içeren ve kumlama sonrası uygulanan primerler veya adezivler, zirkonyaya bağlanma için ideal bir seçenek olarak görünmektedir. Anahtar Kelimeler: Primer, Universal adeziv, Zirkony
