The Fading Affect Bias shows healthy coping at the general level, but not the specific level for religious variables across religious and non-religious events.

The research on fading emotions has shown that unpleasant emotions fade more over time than pleasant emotions, which is a phenomenon referred to as the Fading Affect Bias (FAB). Based on the negative relation between the FAB and dysphoria (Walker, Skowronski, Gibbons, Vogl, & Thompson, 2003), some researchers have argued that the FAB is a healthy coping mechanism (Walker, Skowronski, & Thompson, 2003). As religious variables are related to positive emotions and emotional coping (e.

Effects of the opiate antagonist, naltrexone, on binging antecedents and plasma beta-endorphin concentrations.

The effects of the opiate receptor antagonist, naltrexone, were examined on antecedent thoughts of binging and plasma beta-endorphin concentrations in an adolescent girl who was hospitalized with bulimia nervosa. Significant decreases in urge to binge were obtained during naltrexone administration compared with control sessions. Baseline plasma beta-endorphin concentrations for the bulimic adolescent were not different from those of nonbulimic controls, but plasma beta-endorphins increased significantly during naltrexone administration.

Immunomagnetic separation as a final purification step of liver endothelial cells.

We describe a fast and reproducible method that can be used as a final step in obtaining pure populations of liver endothelial cells. This method employs endothelial cell specific lectin covalently bound to magnetic polystyrene beads (Dynabeads). Evonymus europaeus agglutinin (EEA)-coated Dynabeads were used to purify monkey liver endothelium from Percoll gradient separated nonparenchymal cells.

Effect of phorbol ester and cytokines on matrix metalloproteinase and tissue inhibitor of metalloproteinase expression in tumor and normal cell lines.

The effect of the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) and the cytokines interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) on matrix metalloproteinases (MMP) and metalloproteinase inhibitors was studied in a variety of human cell lines. Expression of the mammalian collagenase (MMP-1), 72-kD gelatinase/type IV collagenase (MMP-2), stromelysin (MMP-3), 92-kD gelatinase/type IV collagenase (MMP-9), and tissue inhibitors of metalloproteinases (TIMP-1 and TIMP-2) was assessed by zymography and Northern blot analysis. MMP-2 and TIMP-2 activities were refractory to TPA, IL-1 and TNF-alpha treatment in most of the cell lines.

Ras levels and metalloproteinase activity in normal versus neoplastic rat mammary tissues.

We have previously reported that activated ras oncogenes can simultaneously switch on the metastatic phenotype and increased capability to degrade type IV collagen. Here the relationship between c-H-ras, metalloproteinase expression and metastatic behavior was studied in N-nitrosomethylurea (NMU)-induced rat mammary carcinomas, which are known to possess activated c-H-ras. When comparing normal rat breast tissue to mammary carcinomas there was no direct relationship between ras DNA levels and neoplastic changes.

Studies on the ability of 65-kDa and 92-kDa tumor cell gelatinases to degrade type IV collagen.

Two major gelatinolytic metalloproteinases (gelatinases) of 65 kDa and 92 kDa were purified from a tumor cell line. Analysis of collagen degradation showed that native full-length Engelbreth-Holm-Swarm (EHS) type IV collagen was not cleaved by the purified gelatinases under conditions where native pepsin-extracted human placental type IV and V collagen and heat-denatured collagens were markedly degraded. However, EHS type IV collagen degradation was noted at 37 degrees C, i.

Basement membrane type IV collagen degradation: evidence for the involvement of a proteolytic cascade independent of metalloproteinases.

Current hypotheses suggest that both the plasmin system and metalloproteinases are involved in tumor invasion of basement membrane. In this study, we demonstrate that plasmin can directly degrade native and denatured type IV collagen in solution as well as in tissue sections. Tumor cell lines secreted plasminogen activators into culture supernatants that activated exogenous plasminogen to degrade type IV collagen in zymograms and to remove collagen IV immunoreactivity from tissue sections.

Life care: an industry with unique financial characteristics.

Despite the financial problems the life care industry has had, these communities are providing a valuable service to residents of retirement age. An understanding of the unique characteristics of the industry will help to ensure that both excellence in service and financial strength are achieved. Long-range planning takes on new significance for management, because the planning horizon must consider lifetime obligations to the resident population.

X-ray epilation for the treatment of trichiasis.

.richiasis is a complication of many different disorders of the eyelids. Treatment is difficult and painful when conventional methods of plucking, surgical excision, electrolysis, or cryotherapy are employed.

Neuromotor development in relation to birth weight in rabbits.

The development of neuromotor patterns in relation to birth weight was studied in the rabbit, a perinatal brain developer. In order to induce intrauterine growth retardation and to increase the number of low birth weight rabbits, experimental ischemia to half the fetuses in each doe was achieved by total ligation of approximately 30% of spiral vessels to the placenta, during the last trimester of gestation. Following natural delivery, the rabbit pups were periodically observed for the appearance of eye-opening and righting reflex, and for the cessations of falling, circling and dragging of hind limbs.

Relations between birth weight and learning ability in young rabbits.

Performance on visual discrimination learning was studied in 41 rabbit pups mainly in relation to their birth weight, but also as functions of their neonatal motor development and weight gain between birth and training time. Partial placental vascular ligation was performed on some fetuses to increase the number of small-for-gestational-age pups. No relation was found between learning ability and either birth weight or rate of motor development.
