In 1994, the Warsaw Royal Castle was honoured with an unequalled artistic and historically valuable art collection in Poland – a donation from the Lanckoroński Family – including two paintings attributed to Rembrandt Harmenszoon van Rijn (1606–1660): Girl in a picture frame and Scholar at his writing table. The most precious of the Polish eighteenth century royal collection pieces were considered lost for about fifty years and that is why Rembrandt’s authorship was put into doubt, mostly as far as the Girl’s portrait is concerned. New research for an up-to-date attribution of both pictures became the main focus for the Warsaw Royal Castle team: between 2004 and 2006 the paintings were examined, treated and reattributed as a result of the cooperation of Polish scientists, conservators and art historians – under guidance of professor Ernst van de Wetering, the head of the Rembrandt Research Project. The two pictures are not typical portraits – they are depictions of unknown persons referred to by the Dutch term tronie. Both models are picturesquely depicted in historical costumes, a frequent Rembrandt feature. Since the 1994 Lanckoroński family donation, Rembrandt’s paintings were on display in the Warsaw Royal Castle, whose museum undertook a project concerning their thorough examination focusing on confirmation of their attribution to Rembrandt. Technical examinations of both paintings were carried out in Cracow and in Warsaw. Experience resulting from the conservation treatment of Rembrandt’s Landscape with the Merciful Samaritan from the Czartoryski Museum in Cracow was helpful to the Warsaw conservation project, as did the support from Martin Bijl, a restorer of Rembrandt’s paintings, a collaborator of the Rembrandt Research Project and former Head of the Conservation Department at the Rijksmuseum. An interpretation of the technical examinations results was consulted with Karin Groen from the Netherlands Institute for Cultural Heritage, another collaborator of the R.R.P. The following types of examinations were carried out: observation in visible (day) light; normal, raking, reflected light and macro photography; IR examination; UV – induced luminescence of paint layers; X-ray examination; identification of wooden panels; stratigraphic analysis and examination of pigments, fillers and binders in samples from the paintings; microscopic and micro chemical analysis; analysis on cross-sections with a LMA 10 laser microspectral analyzer with a ruby laser; microscopic and microchemical analysis realization of scans and spectra images with the SEM-EDS method; examination of paint layer binders with GC-MS and FT-IR as a complementary technique IR absorption spectrophotometry and gas chromatography in connection with gas spectrography.

In the present study a possible hemispheric asymmetry in size evaluation was tested. Subjects were presented with geometrical Vanderplas type figures of various sizes and shapes. The stimuli were exposed in paris, for 100 ms, one after another. The subject's task was to decide (by pressing one of three buttons) whether the second stimulus was the same as, smaller or bigger than the first one. The first stimulus in each pair was exposed unilaterally (randomly in the left or right visual field), and the second in the centre of the screen. Three different interstimulus intervals (ISI) were used: 50 ms, 500 ms, and 2,000 ms. The results showed shorter reaction times for left visual field presentation than for right visual field presentation at the 50 ms and 500 ms interstimulus interval. No laterality effect occured at the 2,000 ms ISI. The results indicate a right hemisphere predominance in stimulus size evaluation. Moreover, the suggest that hemispheric asymmetry is not a stable feature of the brain but is a synamic process that may change in the course of information processing.

Low-level laser therapy is a common physiotherapeutic method used to support rehabilitation of patients with peripheral nervous system diseases, including compression syndromes such as carpal tunnel syndrome. It is believed to have an analgesic, anti-inflammatory and regenerative effect on the treated area. The purpose of this study was to review the literature covering the effectiveness of low-level laser therapy in patients with idiopathic carpal tunnel syndrome. The analysis included reports published between 2002 and 2010 which considered a control group or a reference group. In the studies using low-level laser therapy, the groups differed in terms of the number of patients involved (from 11 to 81 participants), the age - from 26 to 78 and various degrees of carpal tunnel syndrome’s progression. The results were evaluated in relation to a mock treatment or other treatment methods. The following components have been primarily analyzed: clinical symptoms, global grip strength measured using a dynamometer and neurophysiologic parameters. Above all else, the applied low-level laser therapy led to a reduction in pain, an improvement in grip strength, and favourable changes in the terminal latency or nerve conduction velocity

A series of pyrimido[1,2-a]benzimidazole and α-cyanocinnamic acid derivatives have been synthesized in the reactions of Schiff bases 2–7 with selected nitriles containing an active methylene group: malononitrile 8–12, cyanoacetamide 13–16, benzyl cyanide 17–21, benzoylacetonitrile 22–24, cyanoacetate methyl ester 25–28 and benzylacetamide 29. The structures 8–29 were confirmed by the results of elementary analysis and their IR, 1H-, 13C-NMR and MS spectra. The products 8–29 of various chemical structure pyrimido[1,2-a] benzimidazole 8–12, 14–16, 17–21, 23–24, 26 and α-cyanocinnamic acid derivatives 13, 22, 25, 27, 28 were obtained, which are of interest for biological studies or which can be substrates for further synthesis. The selected compounds 10, 13, 14, 17, 19, 21, 23–25 and 28 were screened for their antiproliferative activity in vitro against neoplastic and normal cell lines. The most active two compounds were: 2-(o-bromophenylene)-3-cyano-4-phenyl-1,2-dihydropyrimido[1,2-a]benzimidazole (24) and 3-cyano-4-phenyl-2-(2,4-dimethoxyphenyl)-1,2-dihydropyrimido[1,2-a]benzimidazole (23). However, similarly like cisplatin used as the control, they showed no selectivity towards cancer cells, by inhibiting proliferation of normal mouse fibroblasts in similar manner.
