B-cell chronic lymphocytic leukemia-associated nuclear antigens
One- and two-dimensional polyacrylamide gel electrophoresis were used to compare
the composition of nuclear polypeptides from normal and В-cell chronic lymphocytic leukemia mononuclear cells. Against two electrophoretically-specific nuclear proteins with molecular weight
of 38/39 and 44/46 kD a from leukemic cells rabbit sera were obtained. As it was analyzed by Western blot technique the available antisera recognized the 38/39 kDa antigen in 53 of the 56
(94.6%), while the 44/46 kDa in 46 of the 49 (93.9%) of examined В-CLL nuclear fraction
preparations, but not in normal ones. The pi values of described leukaemia-specific antigens were
determined; p38/39 had pi in the range of pH 6.55 -7.00 and p44/46 - in the range of pH 6.2-6.4.Zadanie pt. „Digitalizacja i udostępnienie w Cyfrowym Repozytorium Uniwersytetu Łódzkiego kolekcji czasopism naukowych wydawanych przez Uniwersytet Łódzki” nr 885/P-DUN/2014 dofinansowane zostało ze środków MNiSW w ramach działalności upowszechniającej naukę
Minimalism in consumption
One of the trends in consumer behaviour that has been gradually gaining strength since the beginning of the 21st century is minimalism, also defined as anti-consumerism, voluntary simplicity and deconsumption. These notions are not identical, although, according to research, the conceptual scope is very approximate. Minimalism means deliberately limiting consumption to the rational sizes that result from the natural, individual, physical and mental characteristics of consumers, while emphasising responsible decision-making in this area. The most common expression of processes related to minimalism is mainly the limitations in quantitative and structural consumption. The aim of the article is to present the state of knowledge about minimalism in consumption on the basis of the analysis of the Polish literature on the subject and the results of scientific research. In the case of consumption, minimalism is compared with other concepts and described in terms of the various research fields of consumption. In the case of trends in consumer behaviour, the term is contrasted with deconsumption and voluntary simplicity. It is indicated as part of a lifestyle of sustainable consumption, and occurs when discussing food wastage as well as fashion. It should be noted that the given issues are related to each other, and their separation/separate treatment results from the adaptation of individual principles and rules by different groups of consumers depending on their own needs
Rola Matki Boskiej w świetle nauk o rzeczach ostatecznych Jacka Liberiusza
In this paper I present Jacek Liberiusz’s sermons and his preaching about the last things (death, last judgment, heaven, hell and purgatory) and the cult of St. Mary. I juxtapose them with the Jean Delumeau’s thesis about the common fear caused by wars, plagues and church’s teaching. Tremendal elements can hardly be found in Liberiusz sermon’s. On the contrary – worldly atrocities or God’s wrath are being mitigated by the infinite mercy and goodness of Virgin Mary. She seems to be the central figure of the cult, even more important than Jesus himself which is characteristic for 17th century polish piety. Sermons by Liberiusz may be an example of more complex and diversed reactions to surrounding cruelty. These atrocities were not necessary replicated in religion, but also in the contact with God people looked for a consolation
Towards the Application of Atorvastatin to Intensify Proapoptotic Potential of Conventional Antileukemic Agents In Vitro
It has been previously revealed that statins used at high concentrations display antileukemic potential towards chronic lymphocytic leukemia (CLL) cells. However, their usage alone in clinical practice may be limited due to possible side effects of high doses of these drugs. On the other hand, combined treatment of leukemia with statins and the conventional chemotherapeutics is questionable because of unknown influence of the first on the standard treatment results. This study has revealed that in vitro atorvastatin increases the proapoptotic potential of cladribine and mafosfamide in CLL cells isolated from peripheral blood of patients. Moreover, a preincubation with the above statin sensitizes leukemic cells to CM-induced apoptosis even at small concentrations of the drug. The usage of atorvastatin together with or followed by the conventional chemotherapy should be considered as therapeutic option for the treatment for this leukemia. Interestingly, CM-resistant patients might have the biggest benefits from atorvastatin administration.Grant no. 1407 from the

Serum levels of IL-6 type cytokines and soluble IL-6 receptors in active B-cell chronic lymphocytic leukemia and in cladribine induced remission.
We have investigated the serum concentrations of interleukin-6 (IL-6) and two IL-6 family cytokines-oncostatin M (OSM) and leukemia inhibitory factor (LIF)-in 63 patients with B-cell chronic lymphocytic leukemia (B-CLL) and 17 healthy controls using the enzyme-linked immunosorbent assay (ELISA) method. Simultaneously, we measured the serum levels of the soluble forms of two subunits of the IL-6 receptor complex-ligand binding glycoprotein 80 (sIL-6R) and glycoprotein 130 (sgp130). The cytokines and receptors were evaluated in 25 untreated patients and 38 patients treated with cladribine (2-CdA), as well as in 17 healthy controls. We have correlated the serum levels of these proteins with Rai's clinical stage of the disease, the response to 2-CdA treatment and some hematological parameters. We have also evaluated the correlation of the IL-6 serum level with the concentration of OSM and IL-6 soluble receptors. IL-6 was measurable in 62/63 (98.4%), OSM in 20/25 (80%) of untreated and 14/38 (37.8%) of the treated patients. sIL-6R and sgp130 were detectable in all 63 patients and LIF in none of the CLL patients. IL-6 serum level in untreated patients was not significantly different as compared to its concentration in the control group (P>0.05). However, in the patients treated with 2-CdA the IL-6 level was significantly lower (P<0.02), and the lowest concentration was found in the patients with complete remission (CR; median 1.4pg/ml; P<0.02). The concentration of sIL-6R was significantly higher in untreated (median 61.8 ng/ml) and treated (median 50.1 ng/ml) CLL patients when compared to normal persons (median 41.2 ng/ml; P=0.04; P<0.001, respectively). There was no difference between the sIL-6R levels in the patients with CR and the healthy controls. In non-responders sIL-6R concentration was the highest and similar to its level in the untreated patients. OSM level was higher in the untreated patients (median 1.8pg/ml) than in the normal controls (median 0.0pg/ml; P<0.001) and in the CR patients (median 0.0pg/ml; P<0.03). The serum concentration of sgp130 was similar in the untreated (median 480 pg/ml) and treated (median 470 pg/ml) patients, as well as in the healthy persons (median 420 pg/ml; P>0.05). We have found significant positive correlation between the levels of sIL-6R and the lymphocytes count in CLL patients (p=0.423; P<0.001). In addition, sIL-6R and OSM serum concentrations correlated also with CLL Rai stage. In conclusion, the serum level of IL-6, OSM and sIL-6R, but not LIF and sgp130, are useful indicators of CLL activity
The body constitution of patients and intubation scales as predictors of difficult intubation considered in relation to the experience of the intubator
The aims of the study were to identify factors that may result in difficulties in
intubation, and to compare the results obtained when an experienced and
when a less experienced anaesthesiologist was involved. The 96 patients included
in the study were evaluated for difficult intubation according to the
following scales: Mallampati, upper lip bite test (ULBT) and Patil. The mobility
of the cervical segments of the vertebral column, the distance between the
jugular notch of the sternum and the chin and the anatomical constitution of
the body were other factors that were taken into consideration. Statistical analysis
was performed in order to identify factors that may result in difficulties in intubation
for an experienced and for a less experienced anaesthesiologist
