Abstract: Coping strategies are not necessarily mutually exclusive and can be used simultaneously, a fact which has rarely been examined in coping research. We examined what kinds of coping profiles could be found in data concerning Finnish health care and service employees (n = 2756). We also studied whether role engagement (family-to-work-enrichment, work-to-family-enrichment, emotional energy at work, and work engagement) and subjective well-being (life, parental, and marital satisfaction, and psychological distress) differ between coping profiles. The data were analyzed through latent profile (LPA) and covariance analyses (Ancovas). LPA revealed seven distinct coping profiles: two active groups, one passive group, one low and two high copers’ groups and one moderate group. These results indicate that coping strategies are not mutually exclusive and that people might use different strategies simultaneously. The covariance analyses revealed that the most significant differences concerned role engagement: active copers showed higher role engagement (e.g. enrichment, work engagement) than moderate or low copers. The findings imply that the indicators of role engagement deserve more attention in coping research in healthy working adults. Keywords: Coping profiles, coping strategies, latent profile analysis, person-oriented approach, role engagement, well-being.Download Full Article |

Abstract: To understand the effects of Vitronectin on cell proliferation and migration in the cell line of hepatocellular carcinoma, SMMC 7721, the effects of Vitronectin on cell proliferation rate or on the prevention of the cells from the apoptotic stimuli were appraised with WST-1 assay; and the morphology of b-Tubulin was observed with con-focal microscope. The effect on migration was detected with transwell chamber. The results show that Vitronectin helps the cells adhere to Petri dish as well as the sustaining of the morphology of b-Tubulin. Vitronectin could enhance the proliferation rate of SMMC 7721 with the concentration-effect mode, and could protect the cells from the stimuli of apoptosis inducer. As to cell migration, the results show that Vitronectin enhance cell migration across the membrane of transwell chamber. According the results, the conclusion could be made that Vitronectin might play important roles in the following biological effects, such as sustaining the morphology of the tumor cells, enhancing the proliferation as well as the migration.

Abstract: The aim of this study was to develop micropropagation protocol for Lonicera caerulea L. Clone 44, Clone 46 and Brązowa, three important invasive woody horticultural plants. Actively growing shoots from the shrubs grown in the field were used for initiation of culture. Shoots were surface sterilized with ethanol, then with sodium hypochlorite and mercury sulfate. MS medium supplemented with cytokinin BAP at concentrations of 1.0 - 4.0 mg·dm-3 had no statistically significant effect on the shoot initiation of selected blue honeysuckle genotypes. Multiplication rate varied depending on the genotype and plant growth regulator concentrations. The highest number of microshoots produced per explant of Clone 44 and Clone 46 was obtained at using 2.0 mg·dm-3 BAP, while of cultivar Brązowa – 1.0 mg·dm-3 BAP. Shoots were rooted in vitro in the presence of IBA and IAA. Microshoots have rooted differently depending on the treatment and genotype. In the case of Clone 4458% rooting was achieved at 2.5 mg·dm-3 IBA and MS basal nutrient medium treatment.

Abstract: The present study was conducted to evaluate production performance and egg quality of four different varieties of native Aseel chicken in comparison with naked neck. A total of 105 adult chickens, 21 birds from each of four varieties of Aseel namely Lakha, Mushki, Peshawari and Mianwali, and 21 birds from naked neck, were maintained separately. The data of daily egg production, daily egg weight and weekly egg quality were calculated for up to ten weeks and analyzed under Completely Randomized Design (CRD) through SAS 9.1 software. Comparison among treatment means were made through Duncan’s Multiple Range (DMR) test. The results showed that egg production of Naked-neck (47.42) was significantly higher (P<0.05) than that of Mushki (34.08), Lakha (31.43), Mianwali (29.59) and Pesahwari (28.7). However,egg weight of Naked-neck (57.52) and Peshwari (55.65) was significantly greater (P<0.05) compared with lakha (54.03), Mushki (53.7) and Mianwali (51.62). Regarding egg quality traits, shell % of Peshawari (13.57) and Nakedneck (13.16) was significantly higher (P<0.05) than that of Lakha (11.89), Mushki (10.19) and Mianwali (9.36). Similarly, Haugh Unit Score of Naked-neck (82.76) and Peshawari (81.95) was significantly greater (P<0.05) than other varieties of Aseel. Albumen % was significantly higher in Mushki (61.83) variety (P<0.05) while yolk % was significantly higher in Mianwali (59.36) variety of Aseel (P<0.05) whereas yolk index showed non-significant (P>0.05) difference in Naked-neck and all varieties of Aseel.
