Enteric neurons are highly adaptive in their response to various pathological processes including inflammation, so the aim of this study was to describe the chemical coding of neurons in the ileal intramural ganglia in porcine proliferative enteropathy (PPE). Accordingly, juvenile Large White Polish pigs with clinically diagnosed Lawsonia intracellularis(More)
Each ganglion of the cervical part of the sympathetic trunk in white rat is supplied by several arteries of diameter of 15--30 micrometers. The arteries arise from three sources: 1) large vessels adjacent to the ganglia, 2) vascular net of connective and muscular tissues surrounding the ganglion, 3) vessels of nerves and interganglionic rami. The vascular(More)
The authors discussed the epidemiological and serological evaluation as well as the clinical symptomatology of thick-borne encephalitis in 215 patients from North-East Poland. They found, among other things, that in 94 per cent of cases the infection was percutaneous from the tick bite and caused via the digestive route in 6 per cent of cases by drinking(More)
Asphalt fume condensate is a skin carcinogen in mice, yet this complex mixture contains relatively low levels of known carcinogenic initiators. Consequently, its biological activity has been attributed to the presence of cocarcinogenic or tumor-promoting agents. One of several proposed mechanisms of tumor promotion is inhibition of intercellular(More)
Among the many alterations of cancer cells is the expression of different surface oligosaccharides. In this work, oligosaccharide expression in living cells (cancer and reference ones) was studied with atomic force microscopy by using lectins as probes. The unbinding force obtained for the same lectin type (concanavalin A or Sambucus nigra) suggested(More)
Frequency of pregnancy miscarriage was analized in 52 women with chronic toxoplasmosis treated clinically. The pregnancy miscarriage was found in 78.4% of cases including abortion-48.7%, premature and immature delivery resulting in death-17.1% and newborns with congenital defects-12.6%, of with 78.6% died shortly after the delivery. The percentage of normal(More)
LiFePO₄ is considered to be one of the most promising cathode materials for lithium ion batteries for electric vehicle (EV) application. However, there are still a number of unsolved issues regarding the influence of Li and Fe-site substitution on the physicochemical properties of LiFePO₄. This is a review-type article, presenting results of our group,(More)
