This study was performed to determine effects of 4 plant growth promoting rhizobacteria (Bacillus subtilis OSU - 142, Bacillus megaterium M - 3, Burkholderia cepacia OSU - 7, and Pseudomonas putida BA - 8) alone and in combinations on fruit set of sour cherry trees (Prunus cerasus L., cv. Kütahya), and to investigate their resulting pomological and chemical characteristics as well as vegetative growth. All the tested bacterial strains alone or some of their combinations have a great potential to increase especially fruit set and plant vegetative growth, and indirectly affect fruit pomological and chemical characteristics. Therefore, they may be considered as biofertilizer for fruit, vegetable, and ornamental plant production in sustainable and ecological agricultural systems. © TÜBITAK.

Electroporation is a safe and efficient method to transfect human tooth germ stem cells (hTGSCs), which are mainly mesenchymal stem cells (MSCs). In this study, pluronic F68 (PF68), a nonionic and low-foaming surfactant, was used for the first time to increase the transfection efficiency in electroporation of hTGSCs. Our results revealed that when PF68 was used in the preincubation, electroporation, and recovery medium, it dramatically increased transfection efficiency. Moreover, use of PF68 did not alter the differentiation capacity of hTGSCs, whereas cells electroporated without PF68 had significantly lower expression of Oct-4, pluripotency marker gene, and alkaline phosphatase (ALP) activity upon osteogenic differentiation. We found that PF68 increases transfection efficiency in both electroporation and chemical transfection of cancer cells lines MCF-7 and HeLa. The study suggested that PF68 might be a safe and reliable chemical to use for increasing transfection efficiency during electroporation and chemical transfections.

Stem cell-based applications have become a popular and promising approach for therapy for a number of disorders including neurodegenerative diseases, degenerative muscle diseases, and osteoporosis, as well as trauma, inflammations, burns, and injuries. Human tooth germ stem cells are an adult stem cell source; they have mesenchymal stem cell properties and show high proliferative and differentiation capacity. Melatonin has been demonstrated to regulate differentiation of human and mouse mesenchymal stem cells into various cell lineages in addition to its other functions in the body. In the current study, the effects of melatonin on osteogenic, neurogenic, adipogenic, chondrogenic, myogenic, and odontogenic differentiation of human tooth germ stem cells were investigated. The results showed that melatonin increases the viability of cells. It significantly augments osteogenic, neurogenic, chondrogenic, myogenic, and odontogenic differentiation of the cells, whereas it reduces adipogenic differentiation capability. These results suggest that melatonin has a great potential to increase differentiation capacity of human tooth germ stem cells and might be useful in regenerative therapy applications involving stem cell differentiations in addition to defining potential treatments for obesity because of its suppressor effects on adipogenesis.

Abstract:Antioxidant activity of the methanol and ethyl acetate extracts of Marchantia polymorpha L., which grows naturally in Turkey, was tested by DPPH and ABTS methods. According to the applied methods, both extracts exhibited moderate activity. Some phenolic compounds that could be responsible for the activity were investigated by RP-HPLC, qualitatively and quantitatively, in the methanolic extract of liverwort. While caffeic acid, chlorogenic acid, rutin, myricetin, quercetin, and kaempferol were not found in the extract, luteolin as the liable antioxidant agent was determined as 0.0052 ± 0.0002% among the investigated compounds.

In this study, the population structure and growth properties of Chalcalburnus mossulensis (Heckel, 1843) caught from Aşkale Region of River Karasu betwen February 1996 and January 1997 were examined.
The age composition of population varied between I and VI ages, and the most abundant age group was the third age group (42.13%). The population was composed of 51.74% females and 48.26% males.
The fork length and the body weights of males and females varied between 8.9-18.1 cm, 3.6-67.9 g and 8.5-18.5 cm, 5.1-79.5 g respectively. The specific and relative growth for length and weight were maximum in the second age. The age-length, age-weight (Von Bertalanffy equations) and length- weight relationships of males and females were calculated as Lt= 20.41 (1-e-0.2485(t+1.47)), Lt= 21.59
(1-e-°-1978(t+2-13)), W = 80.77 (i-e-0-2485^-47))2-828, W = 103.63 (1_e-°-1978(t+2.i3))3.082 and LogW= -1.796+2.828LogFL (r=0.943), LogW= -2.097+3.082LogFL (r= 0.946) respectively. The mean condition factor of males and females were found as 1.023 and 1.047 respectively.

In this study, 26 Pseudomonas spp. were isolated from a stream polluted by factory waste and from petroleum-contaminated soil. The surface tension (ST) of the cultures was used as a criterion for the primary isolation of biosurfactant-producing bacteria. Biosurfactant production was quantified by ST reduction, critical micelle concentration (CMC), emulsification capacity (EC), and cell surface hydrophobicity (CSH). Two of the isolates, P. aeruginosa 78 and 99, produced rhamnolipid biosurfactant. The strains started rhamnolipid production in the logarithmic phase. They decreased the ST of the culture from 73 dyne/cm2 to 29 and 33 dyne/cm2, and the CMC of produced rhamnolipids were 115 and 130 mg/L, respectively. P. aeruginosa 78 and 99 strains emulsified benzene and n-hexane at the highest rates, and the surfaces of these strains were 73% and 65% and 62% and 72% more hydrophobic for benzene and toluene, respectively.

Equisetum telmateia bitkisinin topraküstü kısımları Türkiye’de halk arasında mide ağrısı ve peptik ülser dahil olmak üzere çeşitli hastalıkların tedavisinde halk ilacı olarak kullanılmaktadır. E. telmateia’nın iddia edilen antiülserojenik etkisini incelemek için toprak üstü kısımlarının sulu ve metanollü ekstreleri hazırlanmış ve sıçanlarda etanolle oluşturulan gastrik ülser modelinde incelenmiştir. Farmakolojik deneyler materyalin metanollü ve sulu ekstrelerinin her ikisinin de oral yolla uygulandığında bu ülser modeli üzerinde midede anlamlı bir koruma sağladığını (ülser önleme oranı sırasıyla %77,9 ve %100) göstermiştir (P 0,001). Her iki ekstrenin de aktif olması nedeniyle, materyalin %80 etanol ile ekstre edilmesi tercih edilmiş; ardından %80 etanol ekstresi kloroform ve suyla doyurulmuş n-bütanol ile daha ileri bir ayırıma tabi tutularak, kloroform, n-bütanol ve kalan su ekstreleri elde edilmiştir. %80 etanol ekstresi ve sıvı-sıvı ekstraksiyonla elde edilen ekstreler aynı in vivo deneysel ülser modeline uygulanmıştır. Tüm ekstreler bu model üzerinde istatistiksel olarak kuvvetli antiülserojenik etki göstermiş (P 0.001), ancak en belirgin etki kalan sulu ekstrede görülmüştür (ülser önleme oranı %98,2). Sonuç olarak bu çalışmayla E. telmateia’nın halk arasında peptik ülser üzerindeki kullanımı, sıçanlarda etanolle oluşturulan deneysel gastrik ülser modeli kullanılarak doğrulanmıştır. The aerial part of Equisetum telmateia Ehrh. is used against various conditions including stomachache and peptic ulcer in Turkish folk medicine. In order to prove the claimed anti-ulcerogenic potential of the plant, aqueous and methanol extracts were prepared from aerial parts of E. telmateia and investigated for their anti-ulcerogenic effect on ethanol-induced gastric ulcer model in rats. Pharmacological experiments clearly demonstrated that the oral administration of both methanol and aqueous extracts of Equisetum telmateia Ehrh. plant showed significant stomach protection (77.9% and 100% ulcer inhibition, respectively) against the applied model of ulcerogenesis (P < 0.001). Since both extracts were found significantly active, 80% ethanol was preferred for the extraction of the plant material and this crude methanolic extract was further fractionated by successive solvent extractions with chloroform and H2O saturated n-BuOH to obtain the chloroform and n-BuOH extracts as well as the remaining aqueous extract. The 80% ethanol extract and the solvent extracts were then submitted to pharmacological assay using the same in vivo experimental ulcer model. All the extracts statistically showed potent anti-ulcerogenic effect on this model (P < 0.001). However, the remaining aqueous extract was found prominent (98.2% ulcer inhibition). Consequently, folkloric utilization of E. telmateia on peptic ulcer has been confirmed in the present study by using ethanol-induced experimental ulcer model in rats.

Sak, Olga (Balikesir Author) Endoparazitoid Pimpla turionellae L. (Hymenoptera: Ichneumonidae) zehiri konak türü üzerinde felç edici, sitotoksik ve sitolitik etkiler gösteren biyolojik olarak aktif bileşenlerin karışımıdır. Bu çalışmada, P. turionellae dişilerinden elde edilen zehir salgısının ve doğal parazitlemenin konak tür, Galleria mellonella L. (Lepidoptera: Pyralidae) hemolenfi toplam protein miktarına etkileri belirlendi. Konak pupa ve larvaları için daha önce tepki verdikleri hesaplanan LD99 dozu altındaki farklı zehir dozları kullanıldı. P. turionellae dişileri doğada sadece konak prepupa ve pupalarını parazitlediğinden doğal parazitleme sadece konak pupalarında çalışıldı. Hemolenf toplam protein miktarı parazitlenen ve zehir enjekte edilen tüm konak pupa ve larvalarında tüm dozlarda ve tüm zamanlarda fazla değişiklik göstermedi. Sadece, larvalarda 24 saat sonunda en yüksek zehir dozunda (0,5 kese eşdeğeri zehir) hiçbir işleme tabi tutulmayan kontrol grubundakilere oranla protein miktarında iki kata varan bir artış görüldü. Protein miktarındaki bu artış eğilimi boş enjeksiyon ve sadece fi zyolojik su enjekte edilen larvalarda da görüldüğünden hedef konak evresi olmayan larva evresinde bu artışın zehir ve/veya yaralanmadan kaynaklanmış olabileceği düşünülmektedir. Ancak, diğer hiçbir uygulamada larva protein miktarının 0,5 kese eşdeğeri zehirdekine benzer derecede artış göstermemesi bu artışın sadece yaralanma ve/veya zehir enjeksiyonundan kaynaklanmadığını göstermektedir. Protein artışına konağa enjeksiyon sonucu salgılanan stres proteinlerinin yol açabileceği olasılığı değerlendirilmektedir. Venom from the endoparasitoid Pimpla turionellae L. (Hymenoptera: Ichneumonidae) contains a mixture of biologically active components, which display potent paralytic, cytotoxic, and cytolytic eff ects towards hosts. Here, we further investigate if parasitism or envenomation by P. turionellae alters total protein of its host Galleria mellonella L. (Lepidoptera: Pyralidae). Various venom concentrations representing doses previously determined to yield host responses yet fall below the calculated LD99 were used for pupae and larvae. Parasitization was only assayed for host pupa since P. turionellae females normally parasitize host prepupae and pupae in nature. Hemolymph total protein concentration remained relatively steady at all doses and at all time points tested in parasitized and venom-injected host pupae and larvae. Th e only exception to this trend was with the highest dose of venom (0.5 VRE) at 24 h for larvae that almost 2 times higher amount of protein were detected with regard to untreated ones. It is likely that the increase in protein concentration in a non-permissive host stage in the present study was induced by venom and/or general injury because the same trend was also observed in null- and PBS-injected larvae. However, neither of the treatments increased the protein concentration of G. mellonella larvae to the same extent that 0.5 VRE injection did, indicating that the increase observed in the latter treatment was not simply the result of wounding or injection of fl uid. Th us, we favor the possibility that stress proteins may play a role in this event.

Son yıllarda izole edilen ghrelinin düz kas kasılmaları üzerine düzenleyici etkiye sahip olduğu belirtilmektedir. Bu çalışmada, sıçan uterusundaki spontan kasılmalara ghrelin peptidinin etkileri in vitro olarak araştırıldı. Wistar sıçanların kesilmesini takiben miyometrial stripler izole organ banyosuna yerleştirildi. Spontan kasılmaların başlamasından sonra kontrol kasılmalar 10 dakikalık kayıtlar yapıldı ve izole organ banyosuna kümülatif olarak farklı konsantrasyonda ghrelin uygulamaları yapıldı. İstatistiksel analiz için Wilcoxon signed ranks testi kullanıldı. Kontrol ve 0,01 ?M, 0,1 ?M ve 1 ?M ghrelin uygulanması ile oluşan kasılmaların amplitüdü sırasıyla 2,69 ± 0,32 g (n = 6), 2,71 ± 0,31 g (n = 6), 2,92 ± 0,36 g (n = 6) ve 3,46 ± 0,24 g (n = 6) olarak hesaplandı. Kasılmaların frekansı da sırasıyla 5,17 ± 0,75 (n = 6), 5,17 ± 0,75 (n = 6), 5,33 ± 0,48 (n = 6) ve 8,0 ± 0,77 (n = 6) olarak hesaplandı. Sadece kümülatif 1 ?M ghrelin uygulama grubunda kasılmaların hem amplitüdü hem de frekansı bakımından istatistiksel olarak anlamlı artış gözlendi (P < 0,05). Bu çalışmadaki bilgiler, sıçan miyometriyumundaki spontan kasılmaları ghrelinin indüklediğini kanıtlamıştır. Ghrelin, a recently isolated hormone, has been reported to have modulatory effects on smooth muscle contractility. In this study, we investigated the effects of ghrelin on spontaneous contractions in the rat uterus in vitro. Myometrium strips were removed from Wistar rats following decapitation and placed in a jacketed tissue bath. After initiation of spontaneous contractions, control contractions were recorded for 10 min and various concentrations of ghrelin were added to the tissue bath cumulatively. The Wilcoxon signed ranks test was used for statistical analysis. Application of ghrelin augmented the spontaneous contractions in myometrial strips. The mean peak amplitudes of contractions were 2.69 ± 0.32 g (n = 6), 2.71 ± 0.31 g (n = 6), 2.92 ± 0.36 g (n = 6), and 3.46 ± 0.24 g (n = 6) under control conditions and after application of 0.01 &#956;M, 0.1 &#956;M, and 1 &#956;M ghrelin, respectively. The mean frequencies of contractions were 5.17 ± 0.75 (n = 6), 5.17 ± 0.75 (n = 6), 5.33 ± 0.48 (n = 6), and 8.0 ± 0.77 (n = 6) under control conditions and after application of 0.01 &#956;M, 0.1 &#956;M, and 1 &#956;M ghrelin, respectively. The increase in amplitude and frequency of contractions was significant only after application of 1 &#956;M ghrelin (P < 0.05). Data from this study demonstrated that ghrelin induces spontaneous contractions in a dose-dependent manner in the rat myometrium.

Cell compatibility is one of the prominent requirements for the fabrication of tissue engineering materials. Silk fibroin (SF)
is an excellent material for biomedical applications and shows desirable properties such as good compatibility, minimal tissue reaction,
and tailorable degradability. Poly[(R)-3-hydroxybutyrate] (PHB) has a high percentage of crystallinity and a high melting temperature.
In this study, PHB and SF were blended together to improve the mechanical properties of the SF fibrous structure and the crystallinity
of PHB. Furthermore, the cell–biomaterial interaction on the PHB/SF composite scaffold was expected to be enhanced via the SF. For
this purpose, PHB/SF composite scaffolds were prepared through the use of the electrospinning technique, which is a unique method
for the production of biomaterials on the nanoscale intended for tissue engineering. PHB/SF scaffolds were prepared with different SF
contents and a suitable electrospinning condition was chosen in terms of structure and fiber diameter. The average fiber diameter was 92
± 2.6 nm at a flow rate of 0.4 mL/h, distance of 20 cm, polymer concentration of PHB/SF-0 of 7%:18% (w/w) or 1:1 (v/v), and voltage of
20 kV. Mechanical and crystalline properties of the PHB/SF scaffold were investigated. Adhesion and proliferation of L929 and HaCaT
(mouse fibroblast and immortalized human keratinocyte cell lines) on PHB/SF-0 were examined.

İzole edilen 78 Aeromonas suşunun siderofor, hemolitik, pirazinamidaz, proteaz aktiviteleri ve antibiyotik direnç durumları incelenmiştir. Siderofor üretimi A. hydrophila, A. caviae suşlarının neredeyse tamamında görülürken A. veronii bv. sobria suşlarının yalnızca ikisinde gözlenmiştir. A. hydrophila and A. veronii bv. sobria suşları hemolizin üretirken A. caviae suşları nonhemolitiktir. A. hydrophila suşlarının % 92’si, A. caviae suşlarının % 91’i pirazinamid’i 48 saatten daha az bir zamanda hidroliz etmiş oysa A. veronii bv. sobria suşları yüzde beş oranında aktivite göstermiştir. Proteaz aktivitesi, A. hydrophila, ve A. veronii bv. sobria izolatlarının tamamında (% 100) bulunurken A. caviae izolatlarının % 81,8’de saptanmıştır. Bunlara ilaveten, tüm Aeromonas suşları ampisilin ve tetrasikline karşı dirençli bulunmuştur. A total of 120 fresh water fish samples were evaluated for the presence of Aeromonas spp. A. hydrophila, A. caviae, and A. veronii bv. sobria were isolated from the gills, intestines, livers, and skins of fish, and 78 isolated Aeromonas spp. strains were further examined for siderophore, hemolytic, protease, and pyrazinamidase activities and antibiotic resistance. Siderophore production was demonstrated in almost all of the A. hydrophila and A. caviae strains except for 2 strains of A. veronii bv. sobria. The strains identified as A. hydrophila and A. veronii bv. sobria were the stronger producers of hemolysin, whereas the A. caviae strains were nonhemolytic. It was found that 92% of A. hydrophila and 91% of A. caviae strains hydrolyzed pyrazinamide in under 48 h, whereas 5% of A. veronii bv. sobria strains hydrolyzed pyrazinamide. Protease activity was found in 100% of isolates of A. hydrophila and A. veronii bv. sobria, but in 81% of A. caviae isolates. In addition, all Aeromonas species were examined for antibiotic resistance patterns and were found to be resistant to ampicillin and tetracycline.

Ankara ilinin Haymana ilçesinde halk arasında tedavi, gıda ve diğer şekillerde yararlanılan yabani bitkilerin kayıt altına alınması amacıyla etnobotanik bir saha çalışması yürütülmüştür. Bilgiler seçilen dokuz yerleşim biriminde 160 kişi ile yüzyüze görüşülerek toplanmıştır. Bilgi alınan kişilerin demografik özellikleri değerlendirilerek sonuçların belirginliği SPSS istatistik programı kullanılarak analiz edilmiştir. Araştırma sonuçlarına göre, bilgi alınan kişilerin % 83,8’ünün yabani bitkilerin gıda ya da ilaç olarak kullanılışları hakkında bilgi sahibi olduğu, % 16,2’sinin ise bu konuda bir bilgisi bulunmadığı tespit edilmiştir. Bitkiler hakkında bilgi sahibi olunması ve kullanım sıklığı kişilerin yaşı arttıkça artış göstermektedir. Ancak kişinin eğitim durumu ile bitkiler hakkında bilgi sahibi olması arasında bir ilişki tespit edilememiştir. Çalışmanın yürütüldüğü alanda 18 familyadan 50 bitki türüne ait 103 kullanılış kaydedilmiştir. Bu kullanımlardan 67’si tedavi amaçlı, 28’i gıda olarak ve 8’i diğer çeşitli kullanım şekllerinde olup, en çok Asteraceae (16 tür) ve Lamiaceae (7 tür) familyası bitkilerinin kullanıldığı görülmektedir. Sonuç olarak, Haymana ilçesinin büyük bir kente yakın bir yerleşim alanı olmasına karşılık, yabani bitkilerin yerel halk tarafından tedavi ve gıda amacıyla sık olarak kullanıldığı tespit edilmiştir. Ancak dikkati çeken bir bulgu olarak, daha önce komşu ilçelerde yürütülen etnobotanik çalışmalarda tespit edilen bitkiler ait yerel adlarda ve kullanılış amaçlarında önemli farklılıklar görülmektedir. Bu durumun en belirgin etkeninin son yıllardaki göçler nedeniyle ilçenin demografik yapısındaki değişim olduğu düşünülmektedir. Dietary, therapeutical, and other ethnobotanical utilizations of the wild plants grown in Haymana district of Ankara were investigated. Information was collected by face-to-face interviews with 160 individuals in 9 selected sites. The demographic characteristics of the informants were evaluated and cross-relationships with the recorded data were also analyzed by SPSS statistical software. Results of the study show that 83.8% of the informants recognize the utilization of wild plants either as foodstuff or as remedy, while only 16.2% was unaware of that. Both the knowledge and the utilization of plants significantly increased with the increasing age of the informants. However, there was no significant correlation between the knowledge on plants and the educational status of the informants. Altogether 103 utilizations, recorded in the surveyed area, were obtained from 50 plant species belonging to 18 different plant families. Among these utilizations, 67 were therapeutical, while 28 as foodstuff, and 8 for various other ethnobotanical purposes. Those with the highest number of utilized species; Asteraceae (16 species) and Lamiaceae (7 species) were employed for various purposes. In conclusion, despite the close proximity of the Haymana district to a metropolitan center, wild plants are still recognized and utilized by the inhabitants in the countryside either therapeutically or as foodstuff. However, local plant names and uses were found to be different to some extend than those previously reported in the neighboring districts of Ankara, which might be due to the evolving demographics of the local population with migrations from neighboring provinces or from eastern parts of Turkey.

PIKfyve is an evolutionarily conserved lipid and protein kinase enzyme that has pleiotropic cellular functions. The aim of the present study was to investigate the effects of phosphatidylinositol-3-phosphate 5-kinase (PIKfyve) inhibitor, YM201636, on nonsmall cell lung cancer (NSCLC) cells growth, tumorigenicity, and claudin (CLDN) expressions. Three NSCLC cell lines (Calu-1, H1299 and HCC827) were used to compare the effects of YM201636. Cytotoxic effects of YM201636 were analysed using XTT assay. Malignancy potential of cells assesses with wound healing and soft agar colony-forming assays. mRNA and protein expressions of claudins were analysed by qRT-PCR and immunofluorescence staining. Our results revealed that YM201636 inhibited the proliferation and malignancy potential of Calu-1, H1299, and HCC827 cells in a dose-dependent manner. After YM201636 treatment CLDN1, -3 and -5 expressions increased significantly in HCC827 cells. CLDN3 and -5 expressions also significantly increased in Calu-1 cell line. YM201636 treatment significantly reduced the CLDN1 and increased the CLDN5 expression in H1299 cells. Immunofluorescence staining of CLDN1, -3 and -5 proteins showed a significant increase after YM201636 treatment. Besides, YM201636 induced EGFR mRNA expression in all NSCLC cell lines. Our results have shown that YM201636 inhibits tumorigenicity of NSCLC cells. Furthermore, estimated glomerular filtration rate (EGFR) pathway is important signalling involved in the regulation of claudins. Understanding the mechanisms of PIKfyve inhibitors may improve cancer treatment particularly for EGFR overactivated NSCLC.

The present work was carried out for the production of dipeptidyl peptidase IV (DPP IV; EC 3.4.14.5) using Aspergillus, Penicillium, and Rhizopus strains under solid state fermentation conditions. Response surface methodology was applied for the optimization of the selected operational variables (corn flour, initial moisture content, and cultivation time) for DPP IV activity as the response. The optimal parameters of DPP IV activity for the independent variables, namely the amount of corn flour (% w/w), initial moisture content (% w/w), and cultivation time (days), were evaluated to be 2.44%, 60.85%, and 4.69 days, respectively, using Aspergillus awamori Tl 16. The response for these results was also shown to be in very close agreement with the experimental data.

The continuous production of ethanol from beet molasses by Ca-alginate immobilized Saccharomyces cerevisiae in a packed-bed bioreactor was investigated. The temperature was maintained at 30°C and the dilution rate was 0.22 h-1. Maximum ethanol (4.62%), theoretical yield (82.9%) and volumetric productivity (10.16 gl-1h-1) were obtained from the beet molasses medium containing 10.90% total sugar with 2.0-2.4 mm diameter beads prepared from 2% (w/v) sodium alginate solution. At higher substrate concentrations, substrate was recirculated through the packed-bed bioreactor to increase yields and to decrease residual sugar content. The bioreactor system was operated at a constant dilution rate of 0.22 h-1 for 25 days without loss of original fermentation capacity. Compared to packed-bed bioreactor, lower ethanol concentration (3.94%), theoretical yield (70.7%) and productivity (8.67 gl-1h-1 ) were obtained in the continuous stirred bioreactor.

Wheat landraces could be unique sources of favorable genes for agronomic traits like yield and insect, pest, and disease resistances, as well as quality characteristics that are important for breeding programs. Molecular marker systems off er great opportunities to characterize wheat accessions, which in particular are not morphologically identifi able. In this study, 20 bread wheat landraces collected from different regions of Turkey were characterized by using microsatellite markers (SSRs) and morphological characters. Seventeen morphological characters were used. Fift een SSR primers were prescreened and the 7 most polymorphic primers were employed in characterization. The most polymorphic SSR loci were Xgwm 95 and 295 with 11 alleles, followed by Xgwm 261 and 325 with 9 alleles. The total number of alleles was 63, with an average number of 9 alleles. The dendrogram showed that the bread wheat landraces can be divided into 2 major groups. Based on matrix values, the closest genotypes of landraces were TR 63445 and TR 63886 for molecular data, and TR 37179 and TR 46797 for morphological data. On the other hand, the most genetically different genotypes were TR 37179 and TR 3608 in the SSR analysis, and TR 14851 and TR 3608 in the morphological characterization. These results showed that SSR markers and morphological characters could be successfully used in genetic characterization and genetic diversity in bread wheat landraces that may be useful for wheat breeding programs as genetic resources.

Hot spring sediment and soil samples from West Anatolia in Turkey were investigated for the occurrence of thermophilic Actinomycetes. Isolation was done using Actinomycetes isolation agar (AIA), starch casein agar and glycerol yeast extract agar at 55 degrees C. Extracellular protease activity of the isolates were screened by using AIA plus 1% casein according to the hydrolysis zones surrounding the colonies. Antimicrobial activities of the isolates were also screened by using streaked plate method against a panel of test bacteria. Identification of the isolates was made by cultural, physiological characteristics and 16S rDNA sequence similarity. Sixty-seven thermophilic Actinomyceres isolates were classified in Thermoactinomyces thalpophilus and T. sacchari species. Among these, 62 isolates (92.5%) were found to be extracellular protease producers and 38 isolates (56.7%) were found active against methicillin resistant Staphylococcus aureus and Enterococcus faecalis. Based on these results, we suggest that the thermophilic actinomycetes, which are a part of the biodiversity of the hot springs and soils from West Anatolia in Turkey, are promising sources for novel enzymes and antimicrobial compounds.

The conjugation of glutathione with herbicides and insecticides is considered to be one of the major detoxification mechanisms of plants. This conjugation is catalysed by a family of multifunctional proteins known as glutathione-s-transferases. Treatment of wheat (Triticum aestivum L. cv. Cumhuriyet-75), barley (Hordeum vulgare L. cv. Kaya), chickpea (Cicer arietinum L. cv. Ispanyol), and lentil (Lens culinaris Medik. cv. Kışlık-kırmızı-51) with the selective herbicides 2,4-D (2,4-Dichloro phenoxyacetic acid) and linuron (N-(3,4-dichlorophenyl)-N´-methoxy-N´-methyl urea), and insecticides parathion methyl (O,O-dimethyl O-(4-nitrophenyl) phosphorothioate) and malathion (S-1,2-bis(ethoxycarbonyl)ethyl O,O-dimethyl phosphorodithioate) caused a progressive increase in glutathione-s-transferase activity in roots and shoots. the maximum increase in enzyme activity was observed in parathion methyl treated wheat roots: 485% of control with a parathion methyl concentration of 1.37 mM. A similar but lower increase i n glutathione (GSH) levels was observed for roots and shoots, differing according to the origin and the type of pesticide.

There is no consensus on the properties of an ideal dressing for treating wounds. the aim of this study was to investigate the efficacy of dressings using topically administered bitter melon extract with olive oil, pure olive oil, nitrofurazone, and saline in the healing of ischemic wounds. A sample group of 48 rats was used in the trial. Their wounds were treated with bitter melon extract, pure olive oil, nitrofurazone, and saline. Data were collected between October 2014 and April 2015. the highest percentage (94.7%) of wound healing was observed in the bitter melon extract group and the lowest percentage (86.3%) in the nitrofurazone group. At the end of the 21st day, macroscopic reepithelialization was observed in 9 wounds in the bitter melon extract group (75%), in 6 wounds in the pure olive oil group (50%), and in only 3 wounds in the nitrofurazone and saline groups (25%). It can be concluded that dressing with a bitter melon extract is more efficient in the treatment of wounds than using nitrofurazone or saline, and that dressing with olive oil accelerates wound healing, although not as much as dressing with bitter melon extract.
