Scabies –still current medical and social problem. A retrospective analysis of 193 cases.

Introduction: Scabies is a parasitic skin disease caused by Sarcoptes scabiei. About 200 million casesworldwide each year in people of all ages are reported.

Aim Of Study: Retrospective analysis of records of patients hospitalized at the Department with scabies.

Analysis of DNA polymorphism (RAPD-PCR) and reciprocal effects of geese crossbreeds.

Commercial geese breeding in Poland is based on two strains of White Italian geese (W11 and W33). The crossbreeds W33 (paternal line) and W11 (maternal line) are distributed in Poland under the commercial brand of White Kołuda goose. However, there are several breeds which are covered by the animal genetic resources conservation program and kept as conservative flocks.

Interaction of nitrogen nutrition and salinity in Grey poplar (Populus tremula x alba).

Salinity represents an increasing environmental problem in managed ecosystems. Populus spp. is widely used for wood production by short-rotation forestry in fertilized plantations and can be grown on saline soil.

Nitrogen uptake and metabolism in Populus x canescens as affected by salinity.

External salinization can affect different steps of nitrogen (N) metabolism (ion uptake, N assimilation, and amino acid and protein synthesis) depending on the inorganic N source. Here, we assessed the net uptake of N supplied as nitrate or ammonium and N assimilation (combining metabolite analyses with molecular biological approaches) in grey poplar (Populus x canescens) plants grown under saline (75 mM NaCl) and control conditions. The specific (micromol N g(-1) dry weight fine roots h(-1)) and total plant (micromol N per plant h(-1)) N net uptake rates, total plant N content, total plant biomass and total leaf protein concentration were reduced under saline conditions when plants were supplied with ammonium.

Exogenous supply of glutamine and active cytokinin to the roots reduces NO3- uptake rates in poplar.

The present study shows for the first time the influence of exogenously applied amino acids and cytokinin on the physiological and molecular aspects of N metabolism in poplar trees. In a short-term feeding experiment, glutamine or trans-zeatin riboside (tZR) was added directly to the nutrient solution. NO3- net uptake declined significantly in response to both treatments.
