Anti-helminthic Activity of Consolida orientalis (Gay) Schröd. on Caenorhabditis elegans Nematodes and Determination of Possible Active Ingredients
2021
Hulya Ozpinar
Helminthiasis is an important parasitic disease, many of which are zoonotic, particularly common in developing countries and, in countries with hot and humid climates. Intestinal parasites can cause significant manifestations at all levels of the gastrointestinal tract, as well as anemia and growth retardation. This study aims to demonstrate the anti-helminthic effect of Consolida orientalis on Caenorhabditis elegans, which is a helminth model, and introduce new chemotherapeutic candidate substances with anti-helminthic effect to the literature by identifying possible active ingredients with GC-MS analysis. In our study, flower, leaf, stem and aerial part plant extracts of Consolida orientalis were used at 40 mg/mL, 20 mg/mL, 10 mg/mL, 5 mg/mL, 2.5 mg/mL, 1.25 mg/mL concentrations. In addition, possible active ingredients found in plant extracts were determined by GC-MS analysis. As a result of the study, it was determined that the aerial part, leaf and stem extract of the first four concentrates (40 mg/mL, 20 mg/mL, 10 mg/mL, 5 mg/mL) of Consolida orientalis were more effective than pyrantel pamoate at a concentration of 5 mg/mL. According to our study findings, chemotherapeutics such as Dihidrocarvone and 2(3H)-Benzoxazolone with new antihelmintic-antiparasitic activity are thought to contribute to further research.

As it is common in tropical and temperate zones, mullet species constitute the most important fish species caught along the coast and estuaries of Turkey. In terms of ecology, tourism and and fish productivity (52 kg/ha), Koycegiz-Dalyan Lagoon Ecosystem (KDLES) is the most important lagoon, with a 5500 ha surface area, is the Mediterranean Coast of Turkey. In the dalyan (barrier fish trap) systems; approximately 225 tons (80-405 tons) of mullets are caught to obtain 5 tons of dried fish eggs per year. Seventy percent of fish production in the lagoon is composed of mullets. The mullet samples were collected monthly between October 1992 and September 1994 from eight stations (one of them is a marine station) by trammel nets. The ages were determined using by scales anda ge composition varied form 0 to 6 ages. Species composition of 1159 sampled individuals were proportionally determined as Mugil cephalus 45%, Liza aurata 35%, Liza saliens 14%, Liza ramada 12%, Chelon labrasus 6%. The growth performance indices calculated from von Bertalanffy growth parameters using by all individuals for the M. cephalus, L. aurata, L. saliens, L. ramada and C. labrasus were determined as 2.957, 2.866, 2.692 and 2.719, respectively. The highest growth performance index was calculated for M. cephalus. The growth performance indeces of mullet species in Köyceğiz-Dalyan Lagoon Ecosystem were found around the world averages.

Can Burak Şişman | Ayşen Köktaş Keskin
Günümüzde artan nüfusun beslenme ihtiyacı birim alandan alınan ürün miktarının yani verimin arttırılması ile mümkündür. Ancak en az verim ve üretimin arttırılması kadar elde edilen ürünlerin uygun şekilde değerlendirilmesi ve tüketime sunuluncaya kadar depolanması da önemli bir konudur. Depolamadaki amaç, ürünün özelliklerini ve tazeliğini korumaktır. Ancak uygun koşullar sağlanmadan yapılan depolamalar büyük miktarda kalitatif ve kantitatif kayıplara neden olmaktadır. Bu kayıplar ürüne uygun depolama koşulları ve depo yönetimiyle azaltılabilir. Bu çalışmada Toprak Mahsulleri Ofisi Hayrabolu Şube Müdürlüğü Bölgesinde önemli bir üretim payına sahip olan buğdayın depolanmasında MAYDÜ kullanımının depolama koşulları ve ürün kalitesi üzerine etkileri incelenmiştir. Çalışma sonuçlarına göre MAYDÜ’ de depolamaya etki eden etmenler ve buğday kalite özellikleri değerlendirildiğinde bu depoların kısa süreli depolamalar da kullanılması tavsiye edilebilir.

Mushrooms have been used as food and medicinal purposes for centuries. In this study, some edible Ascomycota were collected in 2018 and 2019 from Niğde, Turkey. Molecular identifications of the samples were performed afterward. PCR products were sent for sequence analysis after ITS fragments were amplified with suitable primers concerning DNA isolation of samples. The obtained data were compared with the Genbank database for samples’ determination. The mushroom samples were determined to be Terfezia claveryi Chatin and Morchella esculenta (L.) Pers. Samples were extracted by ethanol and methanol to determine antimicrobial activity using the disc diffusion method. Antimicrobial zones against microorganisms were measured. Then DPPH radical scavenging effects and total phenolic content of T. claveryi and M. esculenta mushroom samples were studied. The highest antimicrobial activity was observed in ethanol extracts of M. esculenta. When the DPPH radical scavenging activities are taken into account, the activity is increased depending on the concentration. The highest DPPH scavenging activity was found in the extract of M. esculenta with 40.86%. It was determined that the total phenolic substances in methanol extracts of mushroom samples varies between 533.28 ± 1,15-537.34 ±2.20 μg GAE / mg extract.

Öznur Cumhur | Aysu Altaş
Türkiye, sahip olduğu klimatolojik özellikler sayesinde üzüm yetiştirilmesine uygun bir ülkedir. Türkiye’nin verimli topraklarında bol miktarda üzüm üretilmesine ve bağ alanı bakımından dünyanın önde gelen ülkelerinden biri olmasına rağmen üretilen üzümlerin ancak %11 kadarının şarap üretiminde değerlendirildiği bilinmektedir. Türkiye’de şarap sektörünün her aşamasında karşılaşılan zorlukların, kısaca şarap bilimi olarak tanımlanan önoloji eğitimine de yansıdığı ve şarap konusunda kalifiye eleman yetiştirilen okulların sayıca az olduğu görülmektedir. Oysaki Türkiye’nin bağ alanı ve üzüm üretim miktarı açısından en yakın rakiplerinin yer aldığı Avrupa kıtasında durum oldukça farklıdır. Söz konusu ülkelerde önoloji eğitimi büyük önem arz etmekte ve önoloji eğitimini tamamlayanlara önolog unvanı verilmektedir. İçerik analizi yöntemiyle hazırlanan bu çalışmanın amacı, Avrupa’da verilen önoloji eğitimi ile Türkiye’de verilen önolojiye yönelik eğitimi mukayese ederek Türkiye’deki önoloji eğitimi için bazı öneriler ortaya koymaktır. Yapılan çalışma neticesinde; Türkiye’de önoloji eğitiminin, farklı pek çok gerekçe ile ihmal edilmiş bir eğitim alanı olduğu, lisans, yüksek lisans ve doktora düzeylerinde önoloji eğitimi verilmediği, önlisans düzeyinde ise sadece bir devlet üniversitesinde şarap üretim teknolojisi eğitimi verildiği sonuçlarına ulaşılmıştır. Çalışmanın alanyazına, sonraki araştırmacılara, şarap sektörüne ve özellikle şarapla ilgili eğitim veren kurumlara katkı sağlayacağı düşünülmektedir.

Evaluation of soil hydro-physical properties is very important in agriculture and for sustainable management of the land resources. This investigation was conducted to assess some hydro-physical properties of soils in different land use types (LUT) selected (i.e., dry upper land (UD), lowland (LL) and residential area (RA)) at 0-15cm and 15-30cm depths in Bade Local Government Area of Northeastern, Nigeria. Soils were randomly sampled at four points in each LUT and analyzed according to standard soil analysis procedures. Results of the analyses of variance showed that LL had recorded significantly higher clay content, larger soil porosities and high-water retention properties than the other LUT. Soil structural stability index (SSI) and organic carbon (OC) were below optimal range and statistically not different across the land uses. The results also indicated non-significant differences in the hydro-physical properties within the sampling depths. The coefficient of variation (CV) revealed that, slight variation (CV
