They valuable source protein rich vitamins minerals; however, they can also accumulate toxic elements that may pose risks to human health. This study examined mercury concentrations fruiting bodies two edible forest mushroom species: Aureoboletus projectellus Imleria badia. took into account...

In tissue engineering, the possibility of a comprehensive restoration tissue, structure or portion organ is largely determined by type material used. A wide range materials such as graphene and other carbon nanocompounds which have different physical chemical properties can be expected to react differently upon contact with biomolecules, cells tissues. This mini-review describes current knowledge on biocompatibility its derivatives variety mammalian cells, osteoblasts, neuroendocrine...

All animals were divided into groups according gender (males, females) age (calves up one year older than 2 years). Samples mineralized...

This study investigates the effect of graphene scaffold on morphology, viability, cytoskeleton, focal contacts, mitochondrial network morphology and activity in BALB/3T3 fibroblasts provides new data biocompatibility “graphene-family nanomaterials”. We used monolayer applied onto glass cover slide by electrochemical delamination method regular slide, as a reference. The growing was unaltered, cell viability 95% compared to control cells non-coated slide. There no significant difference size...

The aim of this study was to evaluate the concentrations Pb, Cu, Zn, Rb, Cs, Sr and Ba in muscles red deer that were hunted two regions Poland (south-western north-eastern). data obtained evaluated with regards benefits potential risk consumers' health. Samples for investigations collected 2008 2009 from 50 female deer, metal determined by using inductively coupled plasma–mass spectrometric (ICP-MS) method. mean Pb did not differ statistically between equal permitted farm animals. results...

The aim of the study was to evaluate content Cu and Mo in liver, kidneys, skeletal muscles elks from north-eastern Poland. investigation material comprised samples obtained 2010 35 animals. Animals were grouped according age (elks up 2 years over than 3 years). metal concentrations determined using coupled plasma-mass spectrometry (ICP-MS) method. mean 23.08, 5.03, 2.36 mg∙kg(-1) wet weight, respectively. examined as follows: 0.92, 0.42, 0.05 weight (w.w.) muscles. In analysis correlation...

The aim of this study was to analyse the bite forces seven species from three carnivore families: Canidae, Felidae, and Ursidae. material consisted complete, dry crania mandibles. A total 33 measurements were taken on each skull, mandible, temporomandibular joint, teeth. area temporalis masseter muscles calculated, as length arms acting them. Based results, force calculated using a mathematical lever model. This compared estimated areas masticatory bending strength upper canines among...

Zinc is an essential element for maintaining proper functions of animal bodies. It a component many hormones and enzymes participant in the metabolism carbohydrates or synthesis nucleic acids proteins. Animal tissues typically contain 10-200 mg zinc kg–1. Most this amount (98%) can be found inside cells. toxicity associated mainly with secondary copper deficit. The aim present investigation has been to assess contamination environment coats domestic feral cats being indicator. Urban are...

The study aimed at determining the degree of mercury contamination mallards, game waterbirds migrating from regions unknown and establishing whether consumption their meat comprises a hazard to human health in view binding norms concerning content food products. investigations were carried out on 30 mallards shot during duck shooting season which concentrations muscles, liver, kidneys determined using cold vapor atomic absorption spectrometry (CV-AAS) method. mean Hg concentration...

Trivalent chromium is considered an essential element in the nutrition of both animals and humans. Animal studies confirm many beneficial effects organic inorganic compounds on carbohydrate, protein lipid metabolism body. Glucose tolerance factor (GTF) has been demonstrated to involve active form trivalent chromium, which sustains normal glucose metabolism. Cr(III) enzymes ribonucleic acids, accelerate blood clotting increase β-glucuronidase activity. Chromium also participates antioxidant...

The aim of the present investigation is determination zinc content in organism European free-living bison Bialowieza Forest, Poland.  Samples liver, kidney, ribs, muscle and hair were collected winter 2002 during sanitary shots. mineralized a microwave apparatus, contents determined by ICP-OES method.  Comparing least significant differences between groups, higher observed liver males older animals. In kidney found animals rib, level did not differ depending on sex. rib no statistically age observed.

Mercury is a toxic element widely distributed in the natural environment, affecting animals' health. It released into environment from both and anthropogenic sources. The present study analyzed mercury concentrations liver, kidney, heart muscle tissue two species of birds Warsaw area, which were used as bioindicators local environmental pollution with this metal. content examined samples was determined using atomic absorption spectrometry (AAS) utilizing automatic analyzer type AMA 254....

Abstract The objective of the presented study was to compare rubidium concentration in different organs bitches, depending on their health state. Samples muscles, liver, and kidneys collected post mortem from 45 animals, at age 1-8 years, were examined. Chemical analysis conducted using inductively coupled plasma atomic emission spectroscopy method. contents particular varied 2.07 4.52, 1.25 3.81, 1.32 3.78 mg·kg -1 wet weight for muscle, kidney, liver samples, respectively. highest values...

Abstract The aim of the investigations was determination Cu contents in liver, kidneys and skeletal muscles canine females.
