Ariile naturale protejate din regiunea biogeografică panonică, România

Although it only covers 3% of the territory of the European Union, the Pannonian bioregion is home to a high biodiversity with some endemic species. In Romania, the Pannonian bioregion covers 6% of the national territory, and lies on a strip in the Western part of the country. The main purpose of our study is to evaluate the number, surface and distribution of protected natural areas at the level of Pannonian bioregulation in Romania. According to the data processed by specific GIS methods, before the designation of Natura 2000 sites, the area covered by protected areas was 1.59% (22371.86 ha) in the Pannonian bioregion, and now the area coveredby protected areas has increased up to 13, 92% (217409.01 ha). Of the 79 protected bioreales, 2 have management structures, 26 are managed by the custodians and 51 do not have management or custody facilities, and 25 are under an approved management plan

An Artificial Intelligence-Based Environment Quality Analysis System

Part 20: Informatics and Intelligent Systems Applications for Quality of Life information Services (ISQLIS) WorkshopInternational audienceThe paper describes an environment quality analysis system based on a combination of some artificial intelligence techniques, artificial neural networks and rule-based expert systems. Two case studies of the system use are discussed: air pollution analysis and flood forecasting with their impact on the environment and on the population health. The system can be used by an environmental decision support system in order to manage various environmental critical situations (such as floods and environmental pollution), and to inform the population about the state of the environment quality

Investigating Polymorphisms and Expression Profile of Immune, Antioxidant, and Erythritol-Related Genes for Limiting Postparturient Endometritis in Holstein Cattle

This study looked at genetic polymorphisms and transcript levels of immune, antioxidant, and erythritol-related markers for postparturient endometritis prediction and tracking in Holstein dairy cows. One hundred and thirty female dairy cows (65 endometritis affected and 65 apparently healthy) were used. Nucleotide sequence variations between healthy and endometritis-affected cows were revealed using PCR-DNA sequencing for immune (TLR4, TLR7, TNF-α, IL10, NCF4, and LITAF), antioxidant (ATOX1, GST, and OXSR1), and erythritol-related (TKT, RPIA, and AMPD1) genes. Chi-square investigation exposed a noteworthy variance amongst cow groups with and without endometritis in likelihood of dispersal of all distinguished nucleotide variants (p IL10, ATOX1, and GST genes were expressed at substantially lower levels in endometritis-affected cows. Gene expression levels were considerably higher in endometritis-affected cows than in resistant ones for the genes TLR4, TLR7, TNF-α, NCF4, LITAF, OXSR1, TKT, RPIA, and AMPD1. The sort of marker and vulnerability or resistance to endometritis had a significant impact on the transcript levels of the studied indicators. The outcomes might confirm the importance of nucleotide variants along with gene expression patterns as markers of postparturient endometritis susceptibility/resistance and provide a workable control plan for Holstein dairy cows

PATHOLOGICAL TISSUE LESIONS INDUCED BY CHRONIC MERCURY INTOXICATION IN SILVER CRUCIAN CARP CARASSIUS AURATUS GIBELIO

The purpose of this work was to describe the histopathological effects of chronic inorganic mercury intoxication on liver, gills, kidneys, small intestine and skin in silver crucian carp Carassius auratus gibelio. 20 immature 1+-year-old crucian carp were obtained from a private fishfarm and acclimatized to laboratory conditions. After a 3 weeks exposure to a sublethal mercury concentration (0.25 ppm from a HgCl2 stock solution), liver, gills, kidney, small intestine and skin were sampled and processed for histological examination.The main effects observed: numerous interstitial leukocytar infiltrates, followed by glomerulonephritis and tubulonephritis there are at the renal level; fibrosation of peri- and interlobular conjunctive tissue, including ectasiated blood vessel and numerous limphocytar infiltrates enlarged both in perilobular and intralobular conjunctive tissue at the liver level; an disorganization process of gill lamellae by superficial layer alteration, at the gill level; cells of skin epiderma exhibit hiperplazic hypertrophy, epithelial desquamation, intraepithelial edema and citoplasmatic vacuolization; light epithelial distrophic processes and an abundant leukocytar infiltrate both in vilositaire chorion and basal chorion at the small intestine level
