Formy ťažkých kovov a ich vplyv na kvalitu vody v rieke Hornád Problém nahromadenia ťažkých kovov v životnom prostredí je jedným z najväčších problémov súčastnosti. Najviac ťažkých kovov pochádzajúcich z antropogénnej činnosti sa hromadí vo vodnom systéme, vďaka tomu sa ťažké kovy dostávajú cez potravinový reťazec do ľudského organizmu, pre ktorý sú vo zvýšených koncentráciách toxické. Z hľadis...

Rinderpest virus causes a highly contagious and often fatal disease in domestic and wild ruminants. The surface glycoproteins, hemagglutinin (H) and fusion (F) proteins of this enveloped virus are known to confer protective immunity in cattle. We have reported the generation of a recombinant baculovirus expressing H protein and studied its protective properties in cattle. In this report, we dem...

We report results of resistivity sounding of eight locations in the Cerro Chasc on science preserve area. The soil resistivity near the surface was found to be 1000 m at the ve locations in the Pampa La Bola area. The values at the three locations in the Llano de Chajnantor area were much higher, exceeding 3500 m. This di erence probably re ects di erences in water content in the upper soil lay...

Celiac disease (CD) is a malabsorptive disorder precipitated in genetically susceptible individuals by ingestion ofgluten . A significant part of the disease predisposition maps to the HLA class II region, but the primary HLA association is not known (1) . DR3 seems to be a susceptibility allele together with any other DR allele while DR7 is associated to CD almost only in combination with DR3 ...

The autoimmune dermatologic disease pemphigus vulgaris (PV) is associated with the serotypes HLA-DR4 and HLA-DRw6. Based on nucleotide sequence and oligonucleotide probe analysis of enzymatically amplified DNA encoding HLA-DR beta chain (HLA-DRB) and HLA-DQ beta chain (HLA-DQB; henceforth HLA is omitted from designations), we showed previously that the DR4 susceptibility was associated with the...

We previously reported the partial characterization of two cottontail rabbit papillomavirus (CRPV) subtypes with strikingly divergent E6 and E7 oncoproteins. We report now the complete nucleotide sequences of these subtypes, referred to as CRPVa4 (7,868 nucleotides) and CRPVb (7,867 nucleotides). The CRPVa4 and CRPVb genomes differed at 238 (3%) nucleotide positions, whereas CRPVa4 and the prot...

Phylogenetic analyses of closely related species should use information from multiple, independent genes with relatively high rates of sequence evolution. To investigate species for which there are few prior sequence data for single-copy nuclear (scnDNA) genes, primers for gene amplification can be designed to highly conserved regions of exons in order to amplify both coding (exons) and noncodi...
