Evaluation of the protective properties and genotoxic potential of pyrazolo pyridine derivatives against neutron and gamma radiation using the Ames/ test system.

Purpose: Nuclear applications are being increasingly used in various fields, necessitating studies to protect from radiation hazards and their effects. In this study, five different chemical structures of pyrazolo [3,4-b] pyridine derivatives were synthesized. The gamma and neutron radiation protective abilities of these samples were determined and demonstrated their potential use as ingredients in radioprotective drugs.

Plant beneficial traits of endophytic bacteria associated with fennel ( Mill.).

In this study, we used 16S rRNA gene sequence analysis to describe the diversity of cultivable endophytic bacteria associated with fennel ( Mill.) and determined their plant-beneficial traits. The bacterial isolates from the roots of fennel belonged to four phyla: (BRN1 and BRN3), (BRN5, BRN6, and BRN7), (BRN2), and (BRN4).

Evaluation of molecular typing methods for some scab-causing Streptomyces strains from Turkey.

This study was conducted for identifying phylogenetic relationships between 15 scab-causing Streptomyces species including S. bottropensis, S. europaeiscabiei, S.

In Vitro Genotoxic and Antigenotoxic Effects of Ten Novel Synthesized 4-Thiazolidinone Derivatives.

Heterocyclic compounds are found in a variety of drug molecules, and bioactive natural products. 4-Thiazolidinones (4-TZDs), which represent an important class of heterocyclic compounds, are of great interest today with their diverse bioactivities. In this study, ten novel 4-TZD derivatives (C1-C10) were synthesized, characterized by spectroscopic techniques, and their genotoxic, and antigenotoxic properties were investigated in vitro using the Ames Salmonella/microsome mutagenicity assay in the concentration range of 0.

Determination of toxicity and radioprotective properties of bacterial and fungal eumelanin pigments.

Purpose: Determination of the protective property of melanin, an organic polymer class consisting of phenolic and/or indolic compounds isolated from bacteria and fungi, against fast neutron radiation. To show that these melanin samples, which also have antioxidant and metal chelating properties, can be used as an active ingredient for a drug to be developed against neutrons used in nuclear research and medicine.

Materials And Methods: Bacterial and fungal media were prepared, and melanin pigments were produced and isolated.

Investigation of radiation protective features of azadispiro derivatives and their genotoxic potential with Ames/ test system.

Purpose: Five different types of synthesized azadispiro derivatives have been analyzed for radiation absorption capacity and determined their potential to be exploited as substances for a drug to be developed against radiation has been investigated.

Material And Methods: Fast neutron attenuation parameters like the effective mean free path, half-value layer (HVL), removal cross-sections, and neutron transmission number were found with the Monte Carlo simulation Geometry And Tracking (GEANT4) code. Gamma radiation absorption parameters, such as effective atom number (), mean free path (MFP), mass attenuation coefficient (MAC), and half-value layer (HVL) were theoretically determined with WinXCom software.

Diversity and Plant Growth-Promoting Ability of Endophytic, Halotolerant Bacteria Associated with (Pall.) Kuntze.

The diversity of salt-tolerant cultivable endophytic bacteria associated with the halophyte New Zealand spinach ( (Pall.) Kuntze) was studied, and their plant beneficial properties were evaluated. The bacteria isolated from leaves and roots belonged to , , , , , , , , , and .

Diversity and biological activity of culturable endophytic bacteria associated with marigold ( L.).

Endophytes colonizing plant tissue play an essential role in plant growth, development, stress tolerance and plant protection from soil-borne diseases. In this study, we report the diversity of cultivable endophytic bacteria associated with marigold ( L.) by using 16S rRNA gene analysis and their plant beneficial properties.

Biochar Amendments Improve Licorice ( Fisch.) Growth and Nutrient Uptake under Salt Stress.

Licorice ( Fisch.) is a salt and drought tolerant legume suitable for rehabilitating abandoned saline lands, especially in dry arid regions. We hypothesized that soil amended with maize-derived biochar might alleviate salt stress in licorice by improving its growth, nutrient acquisition, and root system adaptation.

Investigation of neutron and gamma radiation protective characteristics of synthesized quinoline derivatives.

Purpose: Quinoline is formed by various natural compounds, such as alkaloids from the cinchona plant, which exhibit various biological activities, and is an important building material for the development of new drugs. Quinoline can be used in anti-radiation drug development but radiation interaction properties must be determined.

Material And Methods: In this study, six types of synthesized quinoline derivatives were used.

Integration of molecular tools in microbial phosphate solubilization research in agriculture perspective.

Phosphorus (P) is the second most crucial nutrient for plant growth after nitrogen. However, its highly reactive nature causes formation of insoluble derivatives and limits uptake by the plant roots. The wide spread applications of P based chemical fertilizers cause detrimental effects on soil fertility, agricultural product quality and environment.

The Effect of Biochars and Endophytic Bacteria on Growth and Root Rot Disease Incidence of Infested Narrow-Leafed Lupin ( L.).

The effects of biochar on plant growth vary depending on the applied biochar type, study site environmental conditions, microbial species, and plant-microbial interactions. The objectives of the present study were therefore to assess 1) the response of growth parameters of lupin and root disease incidence to the application of three biochar types in a loamy sandy soil, and 2) the role of endophytic bacteria in biological control of root rot disease incidence in lupin after the amendment of soil with different biochar types. As biochar types we tested (i) hydrochar (HTC) from maize silage, (ii) pyrolysis char from maize (MBC), and (iii) pyrolysis char from wood (WBC) at three different concentrations (1%, 2%, and 3% of char as soil amendments).

Rapid Detection of Phosphate-Solubilizing Bacteria from Agricultural Areas in Erzurum.

In this study, the newly designed pqq gene-specific primer sets were used for determination of phosphate-solubilizing capabilities of bacterial isolates from the agricultural regions of Erzurum. The specificity of newly designed primer sets (PqqA2F/PqqA2R, Pqq5F/Pqq5R, PqqF2/PqqF2R) were tested against ten isolates, whose phosphate-solubilizing activities were initially proved by the conventional methods. Non-phosphate-solubilizing bacteria were also chosen as negative control.
