Antioxidant activity of CAPE (Caffeic Acid Phenethyl Ester) in vitro can protect human sperm deoxyribonucleic acid from oxidative damage

Purpose: Sperm processing (e.g., centrifugation) used in preparation for assisted reproduction can result in excessive generation of reactive oxygen species (ROS) and potential sperm damage. The use of antioxidants during sperm processing has been shown to prevent iatrogenic sperm damage, including DNA damage. In this study, we evaluated the effect of caffeic acid phenethyl ester (CAPE) on oxidative stress mediated sperm dysfunction and DNA damage. Methods: Semen samples were obtained to liquefy at room temperature. After centrifugation and washing protocols, spermatozoa were incubated in a single step supplemented medium with either of 10, 50 or 100 µmol/L CAPE for 2 hours at 36 °C. After incubation period, MDA levels of seminal plasma were measured. The fragmentation in sperm DNA was detected by light microscopy via use of an aniline blue assay, while ultrastructural morphology was analyzed by transmission electron microscopy. Results: Significant increase has been observed in percent chromatin condensation (assessed by aniline blue staining) and Malondialdehyde (Mmol/L) in oligoasthenoteratozoospermia group before the centrifugation (0.57 ± 0.15). Incubation of samples with 100 µmol/L CAPE after centrifugation resulted in a significantly lower percent chromatin condensation compared to samples incubated without CAPE (0.42 ± 0.12) (P <0.0033). Incubation of all samples with CAPE (10 µmol/L, 50 µmol/L, 100 µmol/L.) after centrifugation resulted in a significantly lower percentage of Malondialdehyde levels. Conclusions: The data suggests that preincubation of spermatozoa with the antioxidant CAPE offers protection against oxidative DNA damage in vitro.The Ministry of Economic Affairs and Employmen

Predictive value of serum and follicular fluid chemerin concentrations during assisted reproductive cycles in women with polycystic ovary syndrome

Aims To evaluate the effect of serum and follicular fluid (ff) Chemerin levels on Assisted Reproductive Technology (ART) outcomes in lean patients with PCOS. Materials and methods The study included 76 infertile reproductive aged women, between 21-35 years who underwent intracytoplasmic sperm injection (ICSI) procedure. Serum and ff Chemerin levels were evaluated. Fertilization and clinical pregnancy rate were compared between the groups. Results Serum (13.32 ng/ml versus 29.82 ng/ml) and ff chemerin (35.90 ng/ml versus 87.60 ng/ml) levels were significantly higher in lean PCOS patients compared to controls (p < .01). Serum (24.5 ng/ml versus 18.4 ng/ml) and ff chemerin (71.7 ng/ml versus 52.8 ng/ml) levels were higher in subjects without clinical pregnancy compared to the subjects with clinical pregnancy (p < .05). A cutoff value of 36.2 ng/ml in the ff chemerin level was found to estimate clinical pregnancy with 83% sensitivity and 52% specificity (Area under the curve 0.66; 95% confidence interval, 0.53-0.79). A cutoff value of 12.7 ng/ml in the serum chemerin level was found to estimate clinical pregnancy with 91% sensitivity and 49% specificity (Area under the curve 0.65; 95% confidence interval, 0.52-0.78). Clinical pregnancy rates were significantly higher in group with lower serum chemerin levels (80.0% versus 30.4%, p < .001). High serum chemerin levels are associated with failure of assisted reproduction [OR:0.1(95% CI, 0.03-0.4, p < .001)]. Conclusions PCOS is associated with higher serum and ff chemerin levels and high serum chemerin level is a risk factor for failed ART cycle

Effects of prunus spinosa L. fruits on experimental wound healing

Farelerde oluşturduğumuz deneysel yara modellerinde, Prunus Spinosa L. metanollü meyve ekstresini kullanarak, bu ekstrenin yara iyileşmesindeki etkisini araştırdık. Otuz iki adet C57/Black fare ile 4 deney grubu oluşturuldu. Birinci grup kontrol grubu, 2. grup taşıyıcı (gliserin) grup, 3. grup Prunus spinosa, 4. grup ma- decassol grubu idi ve her bir grupta farelerin sırtında eksizyonel yara modeli oluşturularak Prunus Spinosa L. ve madecassol 10. gün boyunca uygulandı. Onuncu gün sonunda yara bölgeleri his- tolojik takip için alındı, yara dokuları hematoksilen-eosin ve im- munohistokimyasal (TGF-?, COL1A1) boyalarla boyanarak, yara iyileşmesi için epidermal ve dermal rejenerasyon, granülasyon doku oluşumu, anjiogenezis (yeni damar oluşumu), immunohis- tokimyasal boyalarla yeni oluşan kollajen yapılanması ve TGF ? artışı değerlendirilerek skorlandı. Prunus spinosa L’nin yara do- kusunda iyileşme oranlarını, granülasyon dokusunu, epidermal rejenerasyonu ve anjiogenezisi artırarak gösterdiği yine immü- nohistokimyasal boyamalarda kollajen ve TGF ? oranlarında ista- tistiksel olarak anlamlı bir artışın olduğu gözlendi. Yine 4. günün ve 10. günün sonunda yara kontraksiyonunda ve yara yerinin reepitelizasyonunda ilaç ve madecassol grubunda kontrol gru- buna kıyasla anlamlı bir artış gözlenmiştir. Bulgularımız, Prunus spinosa L’nin yara iyileşmesini desteklediğini göstermiştir. Prunus spinosanın antiinflamatuvar, antioksidan ve antibakteriyel etki- si ile, kollajen sentezini artırarak ve inflamatuvar hücre sayısını azaltarak yara iyileşmesinin tedavisinde kullanılabileceğini dü- şündürdü.We investigated the wound healing efficacy of the methanol extracts of Prunus spinosa L. fruits using an excisional cutane- ous wound model in mice. We used 32 C57/Black mice equally divided into four groups. Group 1 Control, Group 2 vehicle (glyce- rine), Group 3 Prunus spinosa L., Group 4 Madecassol. Prunus spinosa L.and Madecassol were applied for 10 days by creating a excisional wound model on the back of each mouse in each group. At the end of the 10th day, samples from wound areas were taken for histologic follow-up, scoring with hematoxylin- eosin and immunohistochemical (TGF-b, COL1A1) staining. Wo- und healing was evaluated and scored by newly formed collagen structure, increase in TGF b and epidermal and dermal regene- ration, granulation tissue thickness, angiogenesis (new vessel formation). Prunus spinosa L. increased wound healing rates by promoting granulation tissue, epidermal regeneration and angi- ogenesis. In addition there was a significant increase in collagen and TGF [beta] ratios in immunohistochemical staining. At the end of the 4 and 10 days after treatment, a significant increase was observed in wound contraction and re-epithelialization in both Prunus spinosa and madecassol treated groups compared to the control and vehicle groups. Our findings support the be- neficial effects of Prunus spinosa for augmenting wound healing. The anti-inflammatory, antioxidant and antibacterial activities of Prunus spinosa by way of increasing collagen synthesis and dec- reasing the number of inflammatory cells during wound healing have suggested that it may be useful for treating skin wounds

Gastrostomy in hospitalized patients with acute stroke: "NoroTek" Turkey point prevalence study subgroup analysis

Objective: Nutritional status assessment, dysphagia evaluation and enteral feeding decision are important determinants of prognosis in acute neurovascular diseases. Materials and Methods: NöroTek is a point prevalence study conducted with the participation of 87 hospitals spread across all health sub regions of Turkey conducted on 10-May-2018 (World Stroke Awareness Day). A total of 972 hospitalized neurovascular patients [female: 53%, age: 69±14; acute ischemic stroke in 845; intracerebral hematoma (ICH) in 119 and post-resuscitation encephalopathy (PRE) in 8] with complete data were included in this sub-study. Results: Gastrostomy was inserted in 10.7% of the patients with ischemic stroke, 10.1% of the patients with ICH and in 50% of the patients with PRE. Independent predictors of percutaneous endoscopic gastrostomy (PEG) administration were The National Institutes of Health Stroke Scale score at admission [exp (β): 1.09 95% confidence interval (CI): 1.05-1.14, per point] in ischemic stroke; and mechanical ventilation in ischemic [exp (β): 6.18 (95% CI: 3.16-12.09)] and hemorrhagic strokes [exp (β): 26.48 (95% CI: 1.36-515.8)]. PEG was found to be a significant negative indicator of favorable (modified Rankin’s scale score 0-2) functional outcome [exp (β): 0.032 (95% CI: 0.004-0.251)] but not of in-hospital mortality [exp (β): 1.731 (95% CI: 0.785-3.829)]. Nutritional and swallowing assessments were performed in approximately two-thirds of patients. Of the nutritional assessments 69% and 76% of dysphagia assessments were completed within the first 2 days. Tube feeding was performed in 39% of the patients. In 83.5% of them, tube was inserted in the first 2 days; 28% of the patients with feeding tube had PEG later. Conclusion: The NöroTek study provided the first reliable and large-scale data on key quality metrics of nutrition practice in acute stroke in Turkey. In terms of being economical and accurate it makes sense to use the point prevalence method.Amaç: Akut nörovasküler hastalıklarda nütrisyonel durum ve disfaji değerlendirmesi ve enteral beslenme kararı önemli prognoz belirleyicilerindendir. Gereç ve Yöntem: NöroTek, 10 Mayıs 2018’de (Dünya İnme Farkındalık Günü) Türkiye’nin tüm sağlık alt bölgelerine yayılmış 87 hastanenin katılımıyla gerçekleştirilen bir nokta prevalans çalışmasıdır. Hastanede yatan ve bu alt çalışma için toplanan verisi tam olan toplam 972 nörovasküler hasta (kadın: %53, yaş: 69±14 yıl; 845’i akut iskemik inme; 119’u intraserebral hematom ve 8’i post-resüsitasyon ensefalopatisi) analiz edildi. Bulgular: Gastrostomi iskemik inmeli hastaların %10,7, intraserebral kanamalıların %10,1 ve post-resusitasyon ensefalopatisi olanların %50’sine uygulanmıştır. Perkütan endoskopik gastrostomi (PEG) gereksiniminin bağımsız belirleyicileri, iskemik inme grubunda kabul NIHSS [exp (β): 1,09, %95 güven aralığı (GA): 1,05-1,14, puan başına] ile hem iskemik hem de hemorajik inmelerde mekanik ventilasyon uygulanmış olmasıdır [iskemik için: exp (β): 6,18, %95 GA: 3,16- 12,09] ve hemorajik inme için: [exp (β): 26,48, 95% GA: 1,36-515,8]. İnme olgularında PEG uygulaması hastane içi mortalite için bağımsız belirleyici değildi [exp (β): 1,731, 95% GA: 0,785-3,829]. Ancak, PEG uygulanmış olması taburculuk esnasında iyi prognoza (modifiye Rankin skoru 0-2) sahip olabilme için anlamlı bir negatif etmen olarak bulundu [exp (β): 0,032, %95 GA: 0,004-0,251]. Hastanede yatan nörovasküler hastaların yaklaşık üçte ikisinde malnütrisyon ve yutma bozukluğu açısından değerlendirme yapılmıştı. Nutrisyonel status değerlendirmesinin %69’u ve disfaji değerlendirmesinin %76’sı ilk 48 saat içinde gerçekleştirilmişti. Tüple enteral nütrisyon uygulama oranı %39’du. Beslenme tüplerinin %83,5’i ilk 2 gün içinde yerleştirilirken beslenme tüpü olan hastaların %28’ine daha sonra PEG açılmıştı. Sonuç: NöroTek çalışması ile Türkiye’de hastanede yatan akut inme hastalarında nutrisyonel uygulamaların temel kalite ölçütlerine ilişkin ilk güvenilir ve büyük ölçekli veri sağlanmıştır. Ekonomik olması ve doğruluğu açısından nokta yaygınlık yönteminin bu tip verilerin temini için daha fazla kullanılması mantıklıdır
