Investigation of Trace and Macro Element Contents in Commercial Cat Foods.

Background: Nutritional profiles and guidelines are determined by various associations to ensure optimum health of cats and provide pet food manufacturers nutritional recommendations to ensure the well-balanced and nutritionally adequate pet food.

Objectives: It was aimed to determine some trace elements and macro minerals in prescription and non-prescription dry cat foods and compare the contents with the suggested guidelines to evaluate the potential in-compliance.

Methods: A total of 96 dry cat foods were evaluated.

Use of Hair as Matrix for Trace Elements Biomonitoring in Cattle and Roe Deer Sharing Pastures in Northern Italy.

Intensive cattle breeding's environmental challenges are prompting shifts to extensive, pasture-based systems, influencing nutrient and pollutant uptake. PTEs are essential and non-essential elements, regularly found in the environment and organisms, and in which unbalances lead to health issues. Hair analysis, a non-invasive method, provides retrospective PTE exposure evaluation.

Age-related changes on physicochemical properties of the artificial vitreous humor: A practical tool for enhancing ex vivo studies.

The vitreous humor (VH) is a hydrophilic, jelly-like ocular fluid, which is located in the posterior chamber of the eye. The rheological, structural, and chemical properties of VH change significantly during aging, which further causes eye-associated diseases and could be a potential indicator for various diseases. In this study, artificial VH (A-VH) samples were created by taking into account different age groups to observe age-related changes in the physicochemical properties of these samples.

Amounts of tissue magnesium and some trace elements in cats with mammary tumors related to various clinicopathological parameters.

Background: Mammary tumors are one of the major malignancies seen in cats. Researchers have indicated the similarity between the epidemiological and clinicopathological patterns of feline mammary tumors and human breast cancer (HBC). In recent years, the investigation of trace elements in cancer tissues becomes prevalent in HBC due to the role of these elements in biochemical and physiological processes.

Roe Deer () Hair as a Bioindicator for the Environmental Presence of Toxic and Trace Elements.

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 roe deer and understanding if it is a valid bioindicator tool. Hair was collected from 39 hunted roe deer and divided by age (<36 months old/≥36 months old), sex (male/female), and area of origin (urbanized/rural area).

Relationships Linking the Element, Bioactive, Hydroxymethylfurfural, Color of Kars Honeys: a Chemometric Approach.

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 and biochemical properties such as hydroxymethylfurfural (HMF) and color in a chemometric approach.

Investigation of extracellular medium osmolality depending on zinc application and incubation time on A549 cancer cells.

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 extracellular osmolality had an effect on the lung cancer cell line (A549) and how to be changed in ECM according to elements and osmolality depending on incubation time and Zn application.

The effects of copper, zinc and bicarbonate in blood, kidney and liver in rats under intermittent hypobaric hypoxia.

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.

Antioxidant Status, and Blood Zinc and Copper Concentrations in Dogs with Uncomplicated Babesiosis due to Infections.

Introduction: The aim of the study was to demonstrate a link between uncomplicated 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 of canine babesiosis with anorexia, pyrexia, depression, pale mucous membrane, splenomegaly and dark red urine. Microscopic examination of Giemsa-stained peripheral blood smears and the results of PCR confirmed infection.

Elevated serum manganese concentration in dogs as a possible predisposing factor of cerebral babesiosis in dogs.

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). Haematological and biochemical blood tests were performed in all dogs, and the results were analysed statistically.

The comparison of zinc, copper and iron levels in serum, aorta and left internal mammarian artery tissues in coronary by-pass graft surgery patients.

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.
