The problem of selection of attractive regions for investment was discussed. Based on empirical analysis, the need for analytical assistance for investors is advocated. Based on assumption on positive relation of social capital and growth, investigation focuses on social capital influence reflected in economic communication activities and intensity. There are considered mailing activities measured by number of circulating packages and indicators describing economic activities for regions. Then, AI tools are employed to generate rules which identify patterns in data. Results of investigation performed on real data describing Polish provinces and districts encourage to expand the approach and include electronic documents or billings of mobile telephones.

The features of economic culture of the Polish society, revealed in the process of deepening contacts with the West, are considered. The guiding hypothesis is that the processes of institutional transformation and the economic changes initiated in 1989 must have been affected by the cultural legacy of state socialism and of the pre-communist past. The article presents a preliminary, pilot phase of research. The core of the study consisted of twenty in-depth interviews with foreign and Polish businessmen and managers, who faced 'the other side' in the course of their business contacts. The results of this research suggest a generally positive appraisal by Poles of western economic culture, combined with a rather limited understanding of its deeper patterns, an ambiguous character of individualistic attitudes, and an uneven pace of cultural adjustment of different groups to the challenges posed by international economic cooperation.

Purpose: An idea of "double-crush syndrome", introduced by Upton and McComas, is a concept considered for cervical disc disease and the carpal tunnel syndrome. Similar hypothesis can be put forward for lumbar disc disease and the tarsal tunnel syndrome, though the occurrence of the latter has not been studied up to date. The aim of this study was to examine the occurrence of the tarsal tunnel syndrome among patients surgically treated for lumbar disc disease. Material and methods: Electroneurographical examination was performed in 53 in-patients of the Department of Neurosurgery, Medical University of Białystok, who were admitted for surgical treatment of lumbar disc herniation. Results: In 9 of 53 patients, (17%) the terminal latency of the response in the tibial nerve was elongated and the amplitude was depressed to exceed the normal reference range of these parameters, thus diagnosing the tarsal tunnel syndrome. The occurrence of the tarsal tunnel syndrome on the side affected by disc disease was much higher than on the unaffected side (13.2% vs. 7.5%, respectively). Conclusions: A significant sub-group of patients with lumbar disc disease subject to surgical treatment suffer also from impairment of the tibial nerve at the level of the tarsal tunnel. This is likely to affect the results of surgical treatment of disc disease: failed back surgery ought to be considered in respect of this finding.

Introduction:S100 calcium-binding protein B (S100B) is a biochemical marker of astroglial damage. Purpose: To assess the pathophysiological implications of S100B concentrations in blood plasma and cerebrospinal fluid of patients with neurodegenerative central nervous system disorders. Materials and Methods: In this study, we determined and compare S100B concentrations in blood plasma and cerebrospinal fluid obtained from subjects diagnosed with Alzheimer's disease (n=20), amyotrophic lateral sclerosis (n=12), multiple sclerosis (n=40) and the reference group (n=20), using enzyme-linked immunosorbent assay. Results: Concentrations of S100B in plasma collected from patients diagnosed with Alzheimer's disease (252,38±183,50 pg/mL) and multiple sclerosis (164,92±250,14 pg/mL) were above laboratory standards, but in patients with amyotrophic lateral sclerosis (53,96±56,92 pg/mL) and the reference group (2,12 pg/mL) were below laboratory norms (N>75 pg/mL). Concentrations of S100B in plasma collected from patients with Alzheimer's disease (252,38±183,50 pg/mL) were significantly higher than in patients with amyotrophic lateral sclerosis (53,96±56,92 pg/mL) (p<0,029). Concentrations of S100B in CSF collected from the reference group (546,96±236,62 pg/mL) and from patients with Alzheimer's disease (587,53±189,57 pg/mL), amyotrophic lateral sclerosis (404,41±179,56 pg/mL), multiple sclerosis (462,03±146,01 pg/mL) were very similar, and none of pairwise comparisons reached statistical significance. Conclusions: Results of our studies indicate the importance of S100B protein concentration assessment in blood in central nervous system disorders differential diagnostics.

Purpose: Cerebral vasospasm occurs frequently after aneurismal subarachnoid haemorrhage (SAH) and is a dangerous complication. Only a few cases of cerebral vasospasm after intracerebral haemorrhage (ICH) have been reported. To determine the incidence of vasospasm, the authors of this study evaluated the participants’ digital subtraction angiographies (DSA) after these patients had experienced ICH. Materials and methods: Sixty patients with ICH (26 women and 34 men between 20 and 69 years of age, mean age 49.6 years ± 13.9 SD) who underwent cerebral arteriography were included in this study. Cerebral vasospasm was graded as mild (up to 25% of vessel narrowing), moderate (26-50% of vessel narrowing), and severe (more than 50% of vessel narrowing). Results: Vasospasm of the ipsilateral middle cerebral artery (MCA) to the ICH was found in 13 patients (21.6%), the ipsilateral anterior cerebral artery (ACA) in 4 patients, and the posterior cerebral artery (PCA) in one patient. Two patients had a spasm of the contralateral MCA. Severe MCA spasm was found in 3 patients, moderate in 5, and mild in 5. All cases of ACA and PCA spasms were assessed as mild. Conclusions: Cerebral vasospasm is a rather frequent finding in patients who have just experienced ICH. Therefore, practitioners need to assess and monitor the status of the cerebral vasculature in these patients.
