Opis:
Ulcerative colitis (UC) is a inflammatory disease of large bowel. The amount of people suffering from UC increases from year to year. Pathogenesis of this affection is still not entirely clear. Mechanisms of proliferation and apoptosis in colonocytes in the course of the disease are defectedThe aim of the study was to assess the rate of proliferation and intensity of apoptosis in colonocytes in patients with diagnose UC.Material and methods. Colon pathological samples taken from patients with diagnosed ulceraive colitis were examined. Patients were in both clinical and endoscopic remission and were treated with mesalazin. They were patient of Department of General and Colorectal Surgery. To estimate proliferation index dye with monoclonal antibody against Ki67. To determine apoptosis level immunohistochemistry with antybody against Bax was used.Results. Average Ki-67 in the test group was 42,13%, the largest value amounted to 57% and the lowest of 33%. Average value of Bax was 1.47 and ranged between 0-3. High index of bax appear not only in the bottom of the crypt, but also at their outlet.Conclusions. In ulecerative colitis genetic and immunological disturbances occur despite treatment. Mesalazine acting only on certain routes associated with the UC holds the remission, without, however "the molecular remission". Thus, it appears that the results of our research are another proof of the necessary caution in weaning support treatment.

Opis:
The aim of the study was to investigate the changes in proliferation rate, cell cycle and apoptosis of normal skin fibroblasts during fractionated irradiation with a fraction dose of 2 Gy. Fibroblasts were irradiated 5 days per week for 12 days using gamma irradiation. Twenty four hours after each fraction, and for three days after finishing experiment the cells were harvested, fixed, and BrdUrd labelling index (BrdUrdLI), cell cycle and level of apoptosis and debris were assessed. It was found that fractionated irradiation caused disturbances in the proliferation rate and the cell cycle. Irradiation caused also constant, statistically significant increase in the number of G2M cells and level of apoptosis and debris, which was observed even during 3 days after irradiation. Data indicate non equal biological effect of each fraction dose. Block at G2/M phase suggests accumulation of sublethal damage and increased radiosensitivity, which was manifested by elevated level of cell death (apoptosis and debris).

Opis:
This research aims to predict the direction of democratic education in Indonesia through the influence measurement of tolerance, multicultural sensitivity, and historical awareness of the democratic attitude. The multiple linear regression test, coefficient determination test, and model accuracy test were used to measure the influence of the predictors and the dependent variable. The research participants were 300 students, aged between 17 and 18 years, who were taken proportionally in Senior High School (SHS) 1 Surakarta, SHS 5 Surakarta, and SHS 6 Surakarta. Results showed a simultaneous and partial influence of tolerance, multicultural sensitivity, and historical awareness on the democratic attitude. The authors found that there is no diversion in the proliferation of democratic education in Indonesia, in which tolerance, multicultural sensitivity, and historical awareness have a positive influence on the democratic attitude. However, the authors stated that the association between tolerance and democratic education in Indonesia remains problematic, thus, it should be noticed in future research.

Opis:
The aim of the paper is to present the Pakistani nuclear program in the context of Scott D. Sagan’s models describing the causes of nuclear weapons proliferation. The typology consists of three models: the security, the domestic policy, and the norms. The author claims that the Pakistani program would be the most adequately present using the security model. The program was a response to both conventional and nuclear threat from India, which has been in permanent conflict with Pakistan.

The need to strengthen the NPT regime and the internazionalization of the fuel cycle

Opis:
It is widely believed that civilian nuclear cooperation should not lead to proliferation, because there is no direct link between the construction of nuclear weapons and the development of civilian reactors. However, some types of civilian nuclear cooperation, allow the construction of nuclear weapon. This is because all form of civilian nuclear assistance, whether they include training of researchers, and supply of reactors or building fuel processing plants increase knowledge base and technical capabilities of the country, which may increase the likelihood of the spread of nuclear technologies for purposes other than intended. This article attempts to answer the question of whether the cooperation in the field of civil nuclear power, raises the risk of proliferation of dual-use technology for military purposes and undermines international security? How to strengthen and reform the IAEA and its enhanced nuclear safeguards system? The international community must improve existing mechanisms directed to eliminate the risk of nuclear technologies proliferation for military purposes. Another issue that require further support of all IAEA member countries is the need to increase the Agency control and supervision power.

Opis:
In the present study, four new pegylated drugs were synthesized to investigate the anticancer activity. All the compounds were characterized on the basis of FTIR and 1HNMR. The new compounds were evaluated against HCT116 cell line by CellTiter-Glo® 3D cell viability assay. The sustained release pattern of newly synthesized compounds were also evaluated, slow released lasts for 240 h which was confirmed by in vivo and in vitro drug release profile. The sustained and controlled release behavior of pegylated drugs over the extended period of time showed a linear profile and this release pattern was not limited to diffusion process instead supporting chemically controlled release pattern which was dependent only on how fast the compound hydrolyzed. The newly designed pegylated drugs showed almost same killing effect against the cancer cells as the free drugs. The compounds with lower cLogP value showed more antiproliferative (lower IC50) effect due their higher cell permeability.

Opis:
A novel polypeptide, velvet antler polypeptide (VAPPs), having a stimulary effect on proliferation of some cell was isolated from the velvet antler of sika deer (Cervus nippon Temminck). This polypeptide consists of a single chain of 32 amino-acid residues VLSAT DKTNV LAAWG KVGGN APAFG AEALE RM. VAPPs showed marked stimulary effect on rat epidermal cells and NIH3T3 cell line (dose range from 10-40 mg·L-1 and 5-80 mg·L-1, respectively).
