Abstract This study was designed to determine the degree and type of bacterial contamination in boar semen (79 ejaculates from Large White Landrace boars) its consequences for sperm quality during storage (27 extended samples, 16°C five days) under practical conditions artificial insemination (AI). The results revealed presence aerobic bacteria 99% (from 80 370 ×10 6 colony-forming units/mL). Most contained two or three contaminants, while Staphylococcus , Streptococcus Pseudomonas genera...

Milk yield and composition are key factors for dairy industry, both determined by multiple genes. This study contains collective analysis of research on chosen candidate genetic markers associated with milk production traits its technological suitability. The results analyzed studies indicate that polymorphisms in the genes GHR, IGF-1, CSN2, CSN3, FASN, SCD1 affect milk, thus However, BLG show variability across researchers, highlighting need further analysis.

The aim of this study was to analyze changes in sperm plasma membrane integrity, mitochondrial activity, and extracellular environment during storage boar semen at 5 °C, 16 25 °C for 10 days. Progressive motility, integrity (SYBR-14/PI-test HOS test), aspartate aminotransferase (AAT), activity (JC-1-test NADH-dependent NBT assay), as well pH osmolality were assessed nine ejaculates Polish Landrace boars. the stored similar that °C; however, an increase AAT revealed disorders early day 2....

Summary The aim of this study was to identify the occurrence polyovular follicles in porcine ovaries. We investigated presence such relation age, and compared intrafollicular concentrations steroid hormones between poly‐ uniovular follicles. Then we measured size, viability vitro fertilizing ability oocytes from Histological examinations documented pigs at various stages follicular growth. Within antral follicles, number higher ovaries gilts than sows ( P < 0.01). noticed differences size...

Studies were performed on boar semen routinely used at the local artificial insemination (AI) centre. The was stored in a Safe Cell Plus commercial extender 17 degrees C for nine days. aim of our research focused changes sperm plasma membrane integrity. integrity and acrosome as well motility decreased after dilution during storage semen. highest percentage live identified by eosin-nigrosin method, lower SYBR-14/PI test, lowest cells discovered hypoosmotic swelling (HOS) test (P < 0.01)....

Recruitment of fatty acids from adipose tissue is increased during fasting. However, the molecular mechanisms behind fasting-induced metabolic regulation in human and potential impact training state this are unknown. Therefore aim present study was to investigate 1) lipolysis glyceroneogenesis as well 2) on basal oxidative capacity tissue. Untrained [maximal oxygen uptake (V̇o2max) < 45 ml·min-1·kg-1] trained subjects (V̇o2max > 55 ml·min-1·kg-1) fasted for 36 h, abdominal subcutaneous...

Abstract A set of macrocyclic oxamides intended to be used as potential ionophores for lead ions in solvent polymeric membrane electrodes was investigated. The influence the structure ligands (number and distribution oxygen donor atoms ring size) on selectivity examined. Pronounced preference over other divalent some monovalent cations observed 21‐membered‐ring oxadiamides (ionophores 1 7). These exhibited a linear response within activity range 10 −5.4 −10 −15 M Pb(NO 3 ) 2 solutions.

The present study aimed at investigating fasting-induced responses in regulators and markers of autophagy vastus lateralis muscle from untrained trained human subjects. Untrained subjects (based on maximum oxygen uptake, citrate synthase activity, oxidative phosphorylation protein level) fasted for 36 h with biopsies obtained 2, 12, 24, after a standardized meal. Fasting reduced ( P < 0.05) skeletal microtubule-associated protein-1A/1B light chain 3 (LC3)I, LC3II, adaptor sequestosome 1/p62...

Abstract Background Ultrasonography is one of the most important techniques that enable detection and monitoring pregnancy. One such study using this technique assessment hemodynamics fetal umbilical blood vessels. However, there little data on flow in placentomes, which basic structural unit sheep’s placenta. Therefore, aim was to determine Doppler parameters arterial vessels caruncles, cotyledons cord as well measuring venous rates during entire gestation period sheep. Additionally,...

α,ω-Diamino aliphatic ethers react under ambient conditions with dimethyl α,ω-dicarboxylates, in methanol as a solvent, to give the cyclic diamides good yields, and their subsequent reduction lithium aluminium hydride affords respective diazacoronands.

Abstract A versatile and efficient route to macrocyclic amides via high-pressure synthesis is described. Application of the technique allows obtaining title compounds under ambient conditions. The scope limitations this reaction are presented. Key Words: High pressuresynthesismacrocyclic diamides.

The objective of the current study was to evaluate whether blood plasma progesterone (P 4 ) measurements with a time-resolved fluorescent antibody test (TR-FAT) kit designed for humans applicable goats. first experiment verify concentrations P measured by TR-FAT can be used monitor estrous and ovarian activity in goats ( n = 14). Blood samples (322) were collected, ovaries scanned using ultrasonography. second carried out on (60 samples) compare radioimmunoassay (RIA). time interval between...

The objective of the study was to determine selenium status and its distribution in organs free living foxes from deficient areas north-western Poland. Samples harvested 40 shot during 2008-2009 hunting seasons served as experimental material. Selenium concentration determined spectrofluorometrically. tissues depends largely on dietary content. Our indicated that concentrations examined followed order: kidney>liver>spleen>lung>heart kidneys were organ with highest retention this element....

Surgicel is an absorbable material for local haemostasis. Its existence at surgical sites troublesome since it interferes with the radiological images of postoperative complications. The aim this study to demonstrate appearances intraabdominal Surgicel. Materials and methods: Twelve guinea pigs were allocated 2 groups. Animals intraperitoneal (n = 6) retroperitoneal pieces scanned postoperatively. Results: density intensity compared adjacent tissues. All haemostats hypointense tissues next...

The aim of this study was to compare the expression levels SOX9 (SRY-box 9) gene in testes 18 White improved male goats (Capra hircus) divided into three age groups (one, 10 and 15 months with seven, eight individuals per group, respectively). Abnormalities testis development were observed from group 10-month-olds. Additionally, differences that may affect process maturation testicular spermatogenic activity investigated among individuals. tissues analysed using qPCR. Maximal 10-month-old...

In vitro fertilization is a common method of in the case both humans and animals. Although this has developed very rapidly, there are still many unanswered questions about optimal characteristics that oocytes should have for performing procedure. The object study was to describe correlation between diameter size swine relation pubescence. research conducted on ovaries piglets (n = 65) adult 69). Each oocyte examined with without zona pellucida. analysis showed average from antral follicles...
