As a result of tragic industrial accident, highly alkaline red mud sludge inundated settlements and agricultural areas near Ajka, Hungary on October 4, 2010. One the major concerns about aftermaths accident is potential health effects vast amounts fugitive dust from sediment. Thus, we studied chemical physical properties particles its respirable dust, performed toxicity measurements. Under unfavorable meteorological conditions dry sediment could emit very high into air. The number size...
Simultaneously evaluating postthaw viability and acrosome integrity of spermatozoa by flow cytometry would provide a valuable testing tool in both research routine work. In the present study, new triple-stain combination was developed for simultaneous evaluation bovine sperm processed egg yolk-based extender cytometer. SYBR-14 propidium iodide (PI) enabled discrimination cells from yolk debris particles, which instrumental cytometric analyses frozen-thawed sperm, because it implied that...
Effects of triclosan (5-chloro-2′-(2,4-dichlorophenoxy)phenol) on mammalian cells were investigated using human peripheral blood mono nuclear (PBMC), keratinocytes (HaCaT), porcine spermatozoa and kidney tubular epithelial (PK-15), murine pancreatic islets (MIN-6) neuroblastoma (MNA) as targets. We show that (1–10 μg ml−1) depolarised the mitochondria, upshifted rate glucose consumption in PMBC, HaCaT, PK-15 MNA, subsequently induced metabolic acidosis. Triclosan a regression insulin...
Abstract. In recognition of the importance inland waters, numerous datasets mapping their extents, types, or changes have been created using sources ranging from historical wetland maps to real-time satellite remote sensing. However, differences in definitions and methods led spatial typological inconsistencies among individual data sources, confounding complementary use integration. The Global Lakes Wetlands Database (GLWD), published 2004, with its globally seamless gridded depiction major...
Contents The aim of this study was to investigate the effect swim up and Percoll methods select frozen–thawed bull spermatozoa with high quality membrane acrosomal integrity final concentration. Semen samples from six Holstein–Friesian bulls were examined. whole experiment repeated three times. Before after both treatments, subjected a double‐staining method evaluated by brightfield light microscope using 40× dry, or 100× oil immersion objectives. concentration haemocytometer 8.8 × 10 7 /ml...
Cattle populations are highly amenable to the genetic mapping of male reproductive traits because longitudinal data on ejaculate quality and dense microarray-derived genotypes available for thousands artificial insemination bulls. Two young Nordic Red bulls delivered sperm with low progressive motility (i.e., asthenospermia) during a semen collection period more than four months. The were related through common ancestor both their paternal maternal ancestry. Thus, recessive mode inheritance...
Male infertility is an increasing problem in all domestic species including man. Localization and identification of genes involved defects causing male provide valuable information specific events sperm development. Correct condensation the head development acrosome are required for fertile sperm. In Finnish Yorkshire pig population a knobbed defect (KAD) has been reported which appears to be genetic origin. previous studies we have shown that large number affected spermatozoa cystic...
Heat stress is one of the most important issues in broiler flocks impairing animal health and productivity. On a cellular level, excess heat exposure can trigger shock response acting for restoration cell homeostasis by several mechanisms, such as affecting protein synthesis, redox pro-inflammatory cytokine production. The major aim this study was to establish novel avian hepatocyte-nonparenchymal co-culture model investigating effects its interaction with inflammation chicken liver. Cell...
The development of a LoRa network based IoT systems from ideation to realization and initial pilot deployment is presented in this study including case an entrepreneurial business aspect. It found that utilization state the art new components such as LoRaWAN industrial gateways individual off shelf sensing nodes can be very beneficial for short studies. A well-defined target project addition fast cycles both technology paths with minimum redundant tasks maintain agility are necessary...
Studies revealed a global loss of genetic resources for local sheep breeds. Therefore, the current study aimed to introduce and highlight progress made on Hungary’s existing gene conservation program (small Gene Bank). Furthermore, we evaluated breed (Tsigai, Cikta, Racka), season, individual variabilities (n = 24) pre-freeze post-thaw semen stored in Bank enhance The samples were cryopreserved manually, spermatozoa analyzed motility (CASA), viability, chromatin structure, morphometry sperm...
There are still concerns over sperm quality when plant-based diluents used instead of animal-based semen extenders. Therefore, in our study we compared the effects one soybean lecithin-based (AndroMed®) and two egg yolk-based (BullXcell® Optidyl®) commercially available extenders on post-thaw vitro quality. Fifty ejaculates collected from ten bulls were aliquoted into three parts diluted with above-mentioned Post-thaw viability, mitochondrial membrane potential (MMP), plasma integrity,...
During routine evaluation of trypan blue-Giemsa stained semen smears, sperm cells can be found with unstained heads and tails. It was hypothesized that these were immotile should not considered as live. Sperm motility determined in isoosmotic, presumably isotonic blue-stained wet preparations. Bull, ram boar smears hypoosmotic to compare the relationship between percentage tails remaining straight under conditions. Actively moving spermatozoa heads, but never observed The correlation...
A novel, objective, and rapid computed motility inhibition (CMI) assay was developed to identify assess sublethal injury in toxin-exposed boar spermatozoa compared with a subjective visual (VMI) assay. The CMI values were calculated from digital micrographic videos using custom MATLAB® script by contrasting the index of each experiment those background control experiments. Following comparison VMI assays results, it determined that their agreement depended on shape dose-response curve....
Spermatozoa from 2 dairy AI (artificial insemination) bulls (A and B), identified by their abnormal spermiogram with cells depicting frequent macrocephaly, double tails nuclear vacuoles, were case-investigated compared to normal spermatozoa a control sire (C). Head sizes measured morphological abnormalities scored using brightfield differential interference contrast microscopy. The degree of sperm maturation resistance acid-induced DNA denaturation in situ determined after uploading acridine...
