The return to pasture use as an alternative to intensive livestock farming implies some risks with the lack or the excessive presence of potentially toxic elements; in this regard, wild animals have been used as bioindicators for decades. Thus, the purpose of this study is quantifying Cu, Cr, Mn, Zn, Se, As, Cd, Ni, Pb, Al, Fe, and Mg in fur from r...

Honey is a natural food substance considered among functional foods due to its positive effect on human health. Quality of honey is significantly influenced by environmental conditions and botanical origin. This study aimed to determine the element content in honey from Kars, Turkey, as well as the bioactive compounds and certain physicochemical an...

Özet: Elektrokemoterapi, doksanlı yılların başından itibaren beşeri hekimlikte kullanılmaya başlanan, son yıllarda da veteriner hekimlikte kullanılan önemli ve yeni bir lokal antitümöral tedavi yöntemidir. Elektroporasyon ile kemoterapinin birleşimi, hem kemoterapinin yüksek düzeydeki yan etkilerini minimuma indirmiş hem de elektroporasyon sayesind...

Changes in the osmolality of the extracellular medium (ECM) affect cell volume and cellular processes such as cell migration and proliferation. Not only may high concentrations of zinc (Zn) lead to cell death by apoptosis, but Zn is also a physiological suppressor of apoptosis. The aim of our study was to examine whether Zn and regulation of extrac...

Intermittent hypobaric hypoxia is defined as to be below the normal values of partial oxygen pressure at tissue due to hypoxia periods. It can lead to increased reactive oxygen species which causes oxidative damage to DNA, lipids and proteins. The effect of antioxidant defense mechanism varies from tissue to tissue under hypoxic conditions. The aim...

Introduction The aim of the study was to demonstrate a link between uncomplicated Babesia canis infection in dogs and blood concentrations of zinc and copper and erythrocytic antioxidant defence – activities of glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). Material and Methods The study was based on 15 naturally occurring cases...

The aim of this study was to demonstrate a relationship between the occurrence of clinical signs of brain involvement in dogs with babesiosis and the concentration of manganese (Mn) in their serum. The study included seven dogs with early babesiosis (Group 1), seven dogs with cerebral babesiosis (Group 2) and seven healthy dogs (Group 3). Haematolo...

Honey is a natural animal product. The elemental composition of honey varies greatly depending on the source of nectar, honeydew, pollen and environmental conditions. The aim of the present study was to determine the levels of chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), selenium (Se), zinc (Zn), cadmium (Cd), lead (Pb) an...

Trace elements are crucial for vital enzymatic reactions in all metabolic processes. Zinc (Zn) acts as a co-factor for many enzymes. Copper (Cu) and iron (Fe) have pro-atherogenic effects resulting in atherosclerosis. Aorta exposing high pulsatile pressure is sensitive for atherosclerosis because of its fast metabolism and poor nutrition by diffusi...

Background: Cutaneous papillomas are benign proliferative neoplasms. The aetiology and pathogenesis of the disease are very complex. Papillomatosis lesions can be detected anywhere on the body, frequently appearing on the surface of the head, neck, teats, udder, external genital mucosa and upper part of the gastrointestinal tract. The disease is no...

Abstract In this study, mineral element and heavy metal levels in bee pollen produced in various regions of Turkey (20 samples) and imported bee pollen (4 samples), were determined using an Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) device. Mineral and heavy metal levels of bee pollens produced in Turkey were determined to b...

Metabolic diseases such as enzootic ataxia, white muscle disease, and white liver disease are among the most important problems of livestock for sheep. The aim of this study was to analyze whether tears can be used as an alternative diagnostic method in determination of diseases that result from lack or excess of copper, selenium, and cobalt. Sampl...
