Breast cancer (C50) and neoplasms of female genital organs (C51-C58) represent one of the most frequent cancer groups among females in economically developed countries. The Institute of Public Health of the Osijek-Baranja County in collaboration with different county institutes provide updated information on the cancer occurrence and trends in the Osijek-Baranja County (OBC). The aim of this ar...

The most stable fullerene structures from C20 to C60 are chosen to study the energetics and geometrical consequences of encapsulating the rare gas elements He, Ne, or Ar inside the fullerene cage using dispersion corrected density functional theory. An exponential increase in stability is found with increasing number of carbon atoms. A similar exponential law is found for the volume expansion o...

Strain LT/Sv female mice show a high frequency of spontaneous ovarian teratomas arising from parthenogenetically activated follicular oocytes. LT/Sv oocytes also arrest at metaphase of meiosis I, rather than progressing through to metaphase II, as do almost all fully grown oocytes from most other strains. We investigated a new set of recombinant inbred strains derived from BALB/c and C58 (the p...

Phosphatidylcholine (PC), or lecithin, is the major phospholipid in eukaryotic membranes, whereas only 10% of all bacteria are predicted to synthesize PC. In Rhizobiaceae, including the phytopathogenic bacterium Agrobacterium tumefaciens, PC is essential for the establishment of a successful host-microbe interaction. A. tumefaciens produces PC via two alternative pathways, the methylation pathw...

Meprin, a glycoprotein with potent metalloendopeptidase activity, is an integral component of the brush border membrane of mouse kidney. Previously we reported that genealogically related inbred mouse strains (C3H and CBA) are markedly deficient in the activity of this enzyme. We report here that meprin deficiency is inherited as an autosomal recessive trait and that several other inbred strain...

A new light-chain marker has been detected in normal mouse serum immunoglobulin light chains by gel isoelectric focusing. The marker (Ef2) involves the presence of two major and several minor bands in the normal light-chain IF profiles. Strains expressing the marker IF bands are designated Igk-Ef2a, whereas those lacking the bands are Igk-Ef2b. The majority of inbred strains are Igk-Ef2a. Strai...

During a study of proline utilization by mouse lingual epithelial cells (MACCALLUM, Anat Rec 175: 380, 1973), some temporal aspects of the incorporation of the free amino acid by oral bacteria and the appearance of a proline-containing surface coat on oral epithelial cells were determined. Weanling C58 mice were injected intraperitoneally with 166 microcuries/gm of Lproline-2, 3_3H (> 40 curies...

Prostaglandin E2 (PGE2) is the major primary prostaglandin generated by brain cells. However, the coordination and intracellular localization of the cyclooxygenases (COX) and prostaglandin E synthases (PGES) which convert arachidonic acid to PGE2 in brain tissue is not known. We aimed to determine if microsomal and cytosolic PGES (m-PGES-1 and cPGES) colocalize and coordinate activity with eith...

Probes consisting of T-DNA genes from the Ti plasmid of Agrobacterium tumefaciens were used for determining tumorigenicity of strains. Two P-labeled probes hybridized with 28 of 28 tumorigenic strains of the pathogen but not with 20 of 22 nontumorigenic strains. One probe, pTHE17, consists of all but the far left portion of the T-DNA of strain C58. Probe SmaI7 consists of SmaI fragment 7 of pTi...

Replacing the catalytic serine in trypsin with threonine (S195T variant) leads to a nearly complete loss of catalytic activity, which can be partially restored by eliminating the C42-C58 disulfide bond. The 0.69 μs of combined explicit solvent molecular dynamics (MD) simulations revealed continuous rearrangement of T195 with different conformational preferences between five trypsin variants tes...
