in this study proline content and activity of catalase (cat), and ascorbate peroxidase (apx) and level of lipid peroxidation in terms of malondialdehyde (mda) content were measured in transgenic tobacco (nicotiana tabacum cv. wisconsin), over expressing a δ-1-pyrroline-5-carboxylate synthase (p5cs) gene, and non transgenic plants as control. drought stress was applied using polyethylene glycol ...

the purpose of this study was to identify the anatomic structures of the abdominal region of cat throughcomputed tomography (ct) to be used by veterinary radiologists, clinicians and surgeons. the abdominalregion of four cats were scanned twice, with and without using contrast medium in a same position, usinghigh-resolution imaging protocol. slice intervals were 11 mm and were adjusted so that ...

to improve our understanding of helicobacter  infection in cats and to determine whether they are reservoirs for h. pylori  and sources of zoonotic transmission to humans, we selected cats as an experimental animal model for gastric colonization by h. pylori. sixteen stray cats underwent helicobacter  eradication treatment followed by three consecutive oral inoculations of a cocktail of human h...

background :     feline haemotropic mycoplasma are a group of pleomorphic bacteria causing hemolytic anemia along with anorexia, lethargy, dehydration, weight loss and in many cases sudden death in infected animal. however, there is a limited data on the prevalence of these organisms in iranian cats.   methods :    we investigated the presence of feline haemotropic mycoplasma and probable risk ...

three known feline hemoplasmas are mycoplsama haemofelis, ‘candidatus mycoplasma haemominutum’ and ‘candidatus mycoplasma turicensis’. they are described as cause of feline infectious anemia in domestic and wild felids. other blood parasites or blood-related pathogens like concurrent retroviral infections may deteriorate the clinical condition and severity of anemia. the aims of this study were...

Oxidative stress is significant in numerous types of disease including cancer. To protect cells and organs against reactive oxygen species (ROS), the body has evolved an antioxidant protection system that involved in the detoxification of ROS. Single nucleotide polymorphisms (SNP) of anti-oxidative enzymes may dramatically change the activity of the encoded proteins; therefore, certain alleles ...

introduction: this study evaluated the effects of pretreatments with melatonin (mt), and alpha lipoic acid (ala) on lopinavir/ritonavir (lpv/r) -induced serum levels of creatinine (cr), urea (u), uric acid (ua) and kidney levels of malondialdehyde (mda), superoxide dismutase (sod), glutathione (gsh) and catalase (cat) in male albino rats. effects of treatments with mt and ala were also evaluate...

The levels of cathepsins in malignant and surrounding nonmalignant lung tissue were determined in 17 non-small cell lung cancer specimens. Cathepsin (Cat) D activity was assayed using hemoglobin, whereas Cat B and Cat L activities were assayed using fluorimetric substrates, benzoylcarbonyl-Ala-Arg-Arg-7-amino-4-methylcoumarine and benzoylcarbonyl-Phe-Arg-7-amino-4-methylcoumarine, respectively....
