Reproductive Potential of Stone Moroko (, Temminck et Schlegel, 1846) (Teleostei: Cypriniformes: Gobionidae) Inhabiting Central Europe.

Similar to other invasive species, stone moroko is extending its global distribution. The present study aimed to assess the reproductive potential of stone moroko fish in a new habitat in Poland based on analysing the sexual cycle and fecundity. Fish morphometric data, age, and gonadal structures were analysed.

Gas Chromatography-Mass Spectrometry (GC-MS) Analysis of Essential Oils from AgNPs and AuNPs Elicited Lavandula angustifolia in vitro Cultures.

The aim of this study was to determine how the addition of gold and silver nanoparticles to culture media affects the composition of essential oils extracted from Lavandula angustifolia propagated on MS media with the addition of 10 and 50 mg•dm-3 of gold (24.2 ± 2.4 nm) and silver (27.

Concerns of occupational HIV infection among surgical Staff in the light of anti-HIV sero-status and the distribution of Δ32 allele of the CCR5 gene: a cross-sectional study.

Unlabelled: Surgical staff might be considered at most risk of accidental viral infection due to their higher exposure to blood.

Aim: To evaluate surgical staff concerns about occupational HIV infection, to determine contributing factors, to assess their sero-status regarding this pathogen, and the frequency of the Δ32 allele of the CCR5 gene.

Methods: With the use of a self-administered anonymous questionnaire a cross-sectional sero-survey was conducted from February 2009-January 2010 among doctors/nurses from the surgical/ gynaecological wards of 16 randomly selected hospitals in Western Pomerania, Poland.

Molecular connectedness between self and none self-sustainable populations of Chinese mitten crab (Eriocheir sinensis, H. Milne Edwards, 1853) with focus to the Swedish Lake Vänern and the Oder and Vistula River in Poland.

The highly invasive Chinese mitten crabs (Eriocheir sinensis) was studied to reveal the genetic relationship between three none self-sustainable population within the Polish Oder and Vistula River and Lake Vänern in Sweden. Crabs from self-sustainable populations were collected from the Elbe River (Germany), San Francisco Bay (USA) and five Asian river estuaries. Both parsimony and maximum likelihood analysis of the nuclear ITS 1 and ITS 2 regions reveal a similar topological pattern.

Carbon-modified TiO2 for photocatalysis.

Here we present a method to produce TiO2 nanocrystals coated by thin layer of graphitic carbon. The coating process was prepared via chemical vapor deposition (CVD) with acetylene used as a carbon feedstock with TiO2 used as a substrate. Different temperatures (400°C and 500°C) and times (10, 20, and 60 s) of reaction were explored.

Synthesis, dispersion, and cytocompatibility of graphene oxide and reduced graphene oxide.

The synthesis, characterization, and toxicity of graphene oxide and reduced graphene oxide are reported. Prior to the cytocompatibility tests the stability of the suspensions in a wide range of concentrations (3.125-100 μg/mL) of three different dispersants is studied.

Association between polymorphism in bovine PRKAG3 gene and milk production traits.

The aim of the conducted study was to evaluate correlation between genotypes and PRKAG3 compound genotypes and milk production traits (yield of milk, milk fat and milk protein, and protein and fat content in milk). The study covered a herd of 180 Jersey cows. PCR-RFLP method was used for genotyping.

Plasma concentration of calcium, magnesium and phosphorus in chinchilla with and without tooth overgrowth.

The aim of the study was to identify the causes underlying overgrowth of incisors in chinchillas through an analysis of selected plasma electrolyte concentrations, with particular consideration of minerals involved in the formation of osseous tissue, i.e., Ca, Mg, and P.

[Changes of reduction-oxidation balance in pregnant ruminants].

By-products of oxygen metabolism are the element's reactive species and their derivaties. Reactive oxygen species (ROS) and particularly free oxygen radicals (FOR) are characterized by high chemical activity. They can easily react with cell macromolecules (lipids, protein and DNA), leading to change of their structure and function and finally to the cell death and tissue damage.

Study of the genetic structure of dairy cattle based on polymorphism within the aromatase gene.

The study included 1083 Polish Holstein-Friesian strain Black-and-White cows. The genetic structure of the herd was determined on the basis of polymorphism within the aromatase gene (CYP19/Cfr 13I and CYP19/PvuII). Genotypes were identified by the PCR-RFLP method.

Association between leptin gene polymorphisms and growth traits in Limousin cattle.

A total of 129 Limousin calves were used to investigate how leptin gene polymorphisms affect growth traits, such as body weight, average daily gain, wither height, sacrum height and chest girth in beef cattle. Two single nucleotide polymorphisms (SNPs) were genotyped, including the Sau3AI polymorphism in intron 2 and the A59V polymorphism in exon 3. The genotype and allele frequencies for each SNP and the haplotype frequencies for both SNPs were estimated in the studied herd.
