A Preliminary Study of the Poultry Body Weight Effect of Carvacrol in Litter and Of Carvacrol Residue in Organ Tissue of Exposed Chickens.

Introduction: Carvacrol is an essential oil extracted from oregano which can be used as a natural additive in poultry litter and could have a positive impact not only on production rates but also on the quality of poultry meat. The aim of this study was to evaluate the effect of the addition of carvacrol to litter on weight gain and the occurrence of residues in chicken tissues.

Material And Methods: One-day-old Ross 308 chicks were used for the study and were randomly divided into two experimental groups.

Bee Venom Effect on Glioblastoma Cells Viability and Gelatinase Secretion.

Background: The involvement of MMP-2 and MMP-9 in the pathogenesis of various kinds of cancers including glioblastoma is well documented. The evaluation of the anticancer potential of honey bee () venom (BV) consisting of the inhibition of MMP-2 and MMP-9 secretion in a glioblastoma cell culture model was the aim of the study.

Methods: 8-MG-BA and GAMG human primary glioblastoma cell lines vs.

Multifunctional Silver(I) Complexes with Metronidazole Drug Reveal Antimicrobial Properties and Antitumor Activity against Human Hepatoma and Colorectal Adenocarcinoma Cells.

Silver salts and azole derivatives are well known for their antimicrobial properties. Recent evidence has demonstrated also their cytotoxic and genotoxic potential toward both normal and cancer cells. Still, little is known about the action of complexes of azoles with silver(I) salts.

White-Tailed Eagles' () Exposure to Anticoagulant Rodenticides and Causes of Poisoning in Poland (2018-2020).

The white-tailed eagle () is strictly protected in Poland due to its threat of extinction. This study's main goal was to assess their exposure to indirect poisoning by anticoagulant rodenticides (AR). This study presents the investigation results of 40 white-tailed eagles' suspected poisoning cases in the years 2018-2020 in Poland.

The Markers of Stress in Swine Oral Fluid.

Introduction: The study measured the hormonal and protein markers of acute stress, those of oxidative stress and total antioxidant capacity (TAC) in swine oral fluid, determined which of these parameters would be the most appropriate for future livestock welfare assessment and established the time when the samples should be taken.

Material And Methods: Stress was induced in 7 out of 14 castrated six-week-old Danbred×Duroc pigs by immobilisation on a nasal snare at 8 a.m.
