We investigated the effects of PTA on Glu,Asp,Gly andγ-aminobutyric acid（GABA） concentrations and the expression level of cerebral GABA_A receptor in hippocampus.The influence of PTA on epilepsy seizure latency and degree in PNC chronically kindled rats were observed.High performance liquid chromatography（HPLC） was adopted to measure the concentrations of Glu, Asp,Gly and GABA in hippocampus. Reverse transcriptase-polymerase chain reaction （RT-PCR） was used to determine the expression of cerebral GABAA receptor mRNA. Compared with normal rats, the levels of GABA and Gly decreased obviously while the level of Glu and Asp increased significantly in model rats. The cerebral GABAA receptor mRNA level was also decreased at the same time. The difference was statistically different compared to the control group. PTA could prolong the latent period of the penicillin induced seizure and weaken the extent of seizure, compared with the model group without PTA treatment. Moreover, PTA increased the level of GABA and the expression level of GABAA receptor, while decreased the level of Glu significantly. However, it had no obvious effect on the level of Gly and Asp. Pre-treatment of PTA can also increase the GABAA receptor mRNA level. In conclusion, PTA could alleviate the PNC chronically kindled rat seizure. It increased the GABA level and the expression of GABAA receptor, and it decreased the Glu concentration.展开更多

The currently existing algorithms like first come first serve, shortest job first, round-robin, shortest remaining time first, highest response ratio next and varying response ratio priority algorithm have some problems associated with them. Some of them can lead to endless waiting or starvation and some of them like round-robin has problem of too many context switches and high waiting time associated with them. In the proposed algorithm, we have taken care of all such problems. As the novel algorithm is capable of achieving as good results as shortest remaining time first algorithm and also it will never lead to starvation.展开更多

One phenomenon in the care of chronically ill older patients and patients in end of life care is that too much focus is placed on the patient’s disease. This can contribute to anxiety, sadness or sense of isolation. For older people that are chronically ill or in care at the end of life, it is important that the registered nurse can help them to find serenity. Further knowledge is needed about how the concept of serenity is used in relation to the care of older chronically ill patients. Aim: The purpose of this concept analysis was to clarify how serenity is used in nursing and in relation to the care of chronically ill older patients. Method: The study follows Rodgers’ evolutionary method of concept analysis. Findings: Serenity is a state of physical, mental, emotional and spiritual balance when life conditions can be managed or accepted. Through the experience of serenity the chronically ill older patient is able to find or develop the self in order to continue with dignity. The concept is most used at the lowest described levels of the self, including a perception of personal safety. The highest level involves a sense of wholeness and awareness. Conclusion: The concept of serenity is used in relation to chronically ill older patients as a condition where the patient finds balance and thus can manage or accept their situation. Chronically ill older patients will not recover. For that reason it needed a better understanding about what factors to experience serenity are needed. Further research is also needed to examine how registered nurses can support older chronically patients in finding serenity with the help of nursing interventions.展开更多

The objective was to describe and compare the characteristics of resilience in two different age groups of chronically ill oldest older persons living at home and who needed help from home nursing care. Design: Cross-sectional design was used to describe and compare the resilience qualities between the two age groups. Methods: The inclusion criteria were 80 years or older, living at home with chronic disease, receiving help from home nursing care, and with the capacity to be interviewed. A sample of 120 oldest older women (n = 79) and men (n = 41) separated in two age groups, aged 80- 89 and 90+ years, participated in the study. Resilience characteristics were measured by Resilience Scale. Results: The whole group of oldest older people was vulnerable in relation to the characteristics of perseverance, self-reliance, and existential aloneness. Despite reduced physical health they reported a meaningful life, and equanimity. Even if there were no significant differences between the age groups among the oldest older persons in the characteristics of Resilience Scale (RS), in the characteristic of meaning there was a tendency of interaction between age and how much help from home nursing care the participants received. Conclusions: It is important to focus on the individual aging and the risk of developing illness and disabilities rather than focusing on chronologic age. Possessing meaning in life and equanimity may be strengths to meet challenges through illness and growing older.展开更多
