Biological activities and chemical composition of Xanthoria lichens from Turkey

Ali ASLAN

This study presents the biopharmaceutical potential and bioactive composition of Xanthoria lichens (X. candelaria, X. elegans, X. parietina) that wildly grown and traditionally utilized as medicine in North Eastern Anatolia, Turkey, which has specific microclimatic and ecological zones. Chromatographic findings revealed significant levels of parietin compound (35 to 49 mg/g extract), low levels of various fatty acids and a volatile compound; α-terpinene in the extracts. The extracts exhibited pronounced antioxidant potential through reducing and scavenging mechanisms; FCR: 33-38 mg gallic acid ...Более

Kırgızistan çeltik üretimine genel bir bakış

Bermet KIDIRALİYEVA | Nurcamal ÖMÜRZAKOVA | Yılmaz KAYA

Çeltik, Antarktika hariç tüm kıtalarda yetiştirilen dünyanın en değerli gıda ürünleri arasında yer almaktadır. Küresel ölçekte, ekim alanı açısından değerlendirildiğinde buğdaydan sonra ikinci sırada yer almakla birlikte verimi yaklaşık olarak toplam buğday verimine eşittir. Kırgızistan, çeltik yetiştiriciliği bakımından önde gelen ülkeler arasında yer almamakta, bu bölgede sadece yerel ölçekte üretim yapılmaktadır. Kırgızistan’ın güney bölgesi çeltik tarımına elverişli olduğu için son 10 yılda nispeten çeltik ekim alanları ve tüketimi artmıştır. Çeltiğe ilginin artmasına; nüfus artışı, ekonom ...Более

Investigation of the allelopathic effects of lyophilized ethanol extract of Xanthoparmelia somloensis (Gyelnik) Hale lichen on tomato plant

Ali ASLAN

All organisms in nature interact and compete with each other. Various groups of organisms such as algae, lichens, crops and weeds have been found as allelopathic interaction and it is known that lichens have many potent secondary metabolites. The aim of this study was to determine the allelopathic effects of lyophilized ethanolic extract of Xanthoparmelia somloensis (Gyelnik) Hale lichen (XS) on tomato (Lycopersicum esculentum L.) germination and early development stage. Obtained lyophilized ethanolic extracts of XS lichen at concentrations of 50 ppm (XS-50), 100 ppm (XS-100), 200 ppm (XS-200) ...Более

Lichens as Biomonitors of Air Pollutants Deposition: Strategically Important Element Pollution

Ali ASLAN

Investigation of various species of lichen as biomonitors of air pollutants deposition and evaluation of element pollution were aimed. Maximum accumulation was 43.9±2.1 mg/kg in X. somloensis. Strontium in lichen species was quite high. Percentages of strontium for L.pulmonaria, C.furcata, U.longissima, X.somloensis, and F.caperata were between 58 and 78 indicating the efficient accumulation of strontium. Lichens were also accumulated strategically important elements. Maximum contamination factors in lichens were for strontium and tantalum. Maximum contamination factors of hafnium, niobium, li ...Более

Determination of some trace elements in various lichens as biomonitors of pollution and assessment of pollution status

Ali ASLAN

Some trace elements in various lichens as biomonitors of pollution were investigated. Also, the pollution status was assessed by enrichment factor, contamination factor, and pollution load index. Investigated elements were Ta, Bi, Hf, Nb, Ga, Sc, Li, Y, Ce, and Sr. The lichen species were Rhizoplaca chrysoleuca, Umbilicaria vellea, Aspicilia calcarea, Pseudevernia furfuracea, and Cetraria islandica. According to the results, lichen species accumulate Sr element well. The highest trace element accumulated by Pseudevernia furfuracea (21.7±1.0 mg/kg; 75), Rhizoplaca chrysoleuca (31.9±1.6 mg/kg; 6 ...Более

Influence of Peptide Bioregulators on Indicators of Hemostasis in Blood of Irradiated Experimental Animals at Low Altitude Conditions

Gülbübü KURMANBEKOVA | Nurcamal ÖMÜRZAKOVA | Bermet KIDIRALİYEVA

In modern biology and medicine, much attention is paid to the study of the hemostasis regulation of some cell populations by substances of a peptide nature. They have the ability to regulate the functional and proliferative activity of cells and ensure communication in normal and pathological conditions. Research data showed that significant violations of the hemostatic system also occur with radiation damage to the body. One of the first radiation responses involves the coagulation cascade's activation, which leads to the breakdown of fibrinogen and the formation of fibrin clots. The potentia ...Более

Assessment of Some Nutrient Contents and Heavy Metal Accumulation in Some Wild Edible Mushrooms in Türkiye

Ali ASLAN

In this study, it was aimed to identify mushrooms gathered from two different regions and localities of Türkiye and to determine their heavy metal and nutrient contents. Four of the mushrooms (Coprinus comatus (O.F. Müll.) Pers, Cantharellus cibarius Fr., Pleurotus ostreatus (Jacq.) P. Kumm. and Lactarius glyciosmus (Fr.) Fr.) from nearby settlements, while the others (Hydnum repandum L., Pleurotus eryngii (DC.) Quél and Lactarius delicious (L.) Gray)) were collected from rural areas. All species have known and consume by local peoples. All identified species were given along with their trophi ...Более

Chemical Characteristics and Biotechnological Potentials of Mumio

Yılmaz KAYA

Mumio is a valuable substance that ranges in color from pale brown to blackish-brown and is obtained from rock layers in various mountain ranges worldwide, particularly in the Tien Shan ranges of Kyrgyzstan. It is also a natural chemical found largely in the Himalayas, created over ages by the progressive degradation of particular plants by bacteria. Mumio is essentially a nutraceutical product with considerable human health advantages. To fully appreciate the predicted impact of mumio use in the medical area, particularly in neurological sciences, more research at both the fundamental biology ...Более

Candida albicans’ın Moleküler Olarak Tanımlanması

Zeki SEVEROĞLU | Kadırbay ÇEKİROV

İnvaziv mantar hastalıklarının etkenlerinin tanımlanmasında direkt mikroskobik inceleme ve kültür halen altın standart yöntemleridir fakat mantar türleri açısından zor uygulanabilir olmalarından dolayı daha hassas olan moleküler genetik yöntemler tercih edilmektedir. Bu nedenle çalışmamızda moleküler yöntemler kullanılarak etkenin orijini/fungus genotipini tanımlamak amaçlanmıştır. Bakırköy Dr. Sadi Konuk Eğitim ve Araştırma Hastanesi’nde yatan veya polikliniklere başvuran 0 ile 78 yaş arasındaki hastalardan kan, idrar, balgam, diş, ağız içi ve vajen olmak üzere 150 klinik örnek değerlendirmey ...Более
