Phytophthora agathidicida is a highly virulent pathogen of kauri (Agathis australis) and the causal agent dieback disease in New Zealand’s forests. This study aimed to identify microbial isolates isolated from forest soils that inhibited growth P. agathidicida. Three different forms vitro bioassays were used assess inhibition each isolate on mycelial Furthermore, head space (HS) solid-phase mic...

The breast cancer susceptibility gene BRCA2 has been suggested to function as a "caretaker" of the genome. Cells without wild-type BRCA2 are deficient in repairing DNA damage. However, whether BRCA2 can also suppress oncogenesis by regulating cell proliferation remains to be determined. To address this question, the expression of wild-type BRCA2 protein was reconstituted, in an either constitut...

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most common pharmacological group that has three primary therapeutic effects including anti-inflammatory, anti-pyrexia, and analgesia. In this study, seven of NSAIDs were tested against two species of skin pathogenic fungi (dermatophytes). Percentage inhibition was determined for effective agents. Diclofenac, Aspirin and Naproxen showed muc...

Growth inhibition of Aspergillus fumigatus,Aspergillus flavus and Fusarum solani exposed to the essential oils including Thyme, Agastache and Satureja were studied. Disc Diffusion Method was used to evaluate the fungal growth inhibitory effects of the essential oils. Minimal inhibitory concentration (MIC) and minimal fungicidal concentration (MFC) of the oils were determined and compared with ...

Cultured malignant human lymphocytes are highly sensitive to growth inhibition by thymidine (50% inhibitory dose congruent to 10(-5) M). Growth inhibition reflects sustained elevation of the deoxythymidine 5'-triphosphate pool associated with secondary elevation of the deoxyguanosine 5'-triphosphate pool and reduction in the deoxycytidine 5'-triphosphate (dCTP) pool. Deoxycytidine was capable o...

Background: Some fungi have double host attacks for animals and plants, among them Alternaria alternata. Using a local medicinal plant such as Ephedra alanda is one way to fight its spreading. Aim: Evaluate the effect of different extracts against mold Material Methods: This work used solvent by successive extraction (Hexane, Chloroform, Ethyl acetate, Methanol) total alkaloids evaluate Anti- a...

background tyrosinase, as a copper-containing enzyme, is widely distributed in different levels of life span. it is also a key enzyme in melanin biosynthesis, which plays a crucial role in determining the color of mammalian skin and hair. objectives the current study aimed to determine the effect of a palladium complex on cresolase and catecholase reactions of mushroom tyrosinase (mt). material...

The cytotoxic activity of ethanolic extracts of Thymus vulgaris, Thuja orientalis and Achillea millefolium was investigated on various growing tumor cell lines. MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia ...
