Cancer is increasingly apparent as a systems-level, network happening. The central tendency of malignant alteration can be described as a two-phase procedure, where an initial increase of network plasticity is followed by reducing plasticity at late stages of tumor improvement. Cancer stem cells (CSCs) are cancer cells that take characteristics associated with normal stem cells. Cancer therapy has been based on the concept that most of the cancer cells have a similar ability to separate metastasise and kill the host. In this review, we addressed the use of nanotechnology in the treatment of cancer stem cells.

Background: Establishing cost-effective informal care services for lonely older adults living at home in developing countries can be an innovative approach for improving their well-being. This study investigated the effectiveness of an informal home care support intervention program (HoSIP) reducing the loneliness and improving quality of life of lonely community-dwelling older adults. Methods: This quasi-experimental pre-post study employed a non-randomized control group design with a 12-week intervention period and three follow-up points at the end of the HoSIP. Questionnaires were used to measure feelings of loneliness (20-item UCLA Loneliness Scale), quality of life (Control, Autonomy, Self‐Realization and Pleasure Scale), general health (12-item General Health Questionnaire), social network (six-item Lubben Social Network Scale), social support (12-item Multidimensional Scale of Perceived Social Support), and self-care ability (17-item Self-care Ability Scale for the Elderly). Repeated-measures analysis of variance was used to gauge the effect of the intervention program over time and in comparison to the control group. Data analyses were performed using the IBM SPSS Statistics software (IBM Corp., USA). Results: We found a significant relationship between the outcome variables, including feelings of loneliness (P<0.001) and quality of life (P<0.001), at different stages of measurement. Despite the positive feasibility results, the implementation of the HoSIP faced challenges due to a lack of facilities (e.g., place restriction for holding educational classes, educational facilities like computers, video projector, and whiteboard at daycare center) and the absence of supporting organizations. Conclusion Utilizing the existing capabilities of older adults to provide online and face-to-face care services can be a cost-effective way to improve their quality of life and reduce loneliness. The process of facilitating such informal care services for lonely older adults should be managed by either governmental or non-governmental organizations to reduce the rate of social isolation among this vulnerable population.

Objective To investigate the healing effects of two herbal preparations. Methods For this purpose, 106 wistar rats were divided into 9 groups including a control, eucerine, phenytoin, Urtica dioica (U. dioica) (2%), U. dioica (5%), Sambucus ebulus (S. ebulus) (2%), S. ebulus (5%), combination (2%), and combination (5%) groups. The control group remained untreated, the eucerin and phenytoin groups were considered as the negative and positive controls respectively, and the remaining groups received different concentrations of the ointments. Full thickness wounds were made. The healing process of the wounds was investigated on day 7, 14 and 21 of the experiment. Several factors including the number of fibroblasts, new vessel formation (angiogenesis), thickness of the granulomatous tissues (GT), and the overlying epithelium were analyzed. Results Among the studied groups, all of the treatment groups were significantly different from the control, eucerin, and phenytoin groups in a positive manner with regard to all studied factors (P ≤ 0.05). However, the best results were observed with the S. ebulus (2%) and the combination 2% groups (P ≤ 0.05). Conclusions Topical ointments prepared from the extracts of U. dioica and S. ebulus and their combination possess strong wound healing properties. It is postulated that a synergistic effect may exist between the two extracts since the combination 2% showed better results than the sole extracts.

Introduction: Motivation is important as one of the major factors for incidence of behaviour in all behaviours such as learning, performance, perception, accuracy, recall, forgetting, thinking, creativity and emotions. The interaction of trainers and nursing students plays a significant role in clinical education and achieving educational objectives. Aim: Considering the wide role of nursing trainers in students leaning clinical experience and their motivation, and based on qualitative studies done so far, the present research was performed to investigate the relationship between educational behaviours of clinical trainers and motivation toward science learning among nursing students. Methods: This cross sectional study was performed on 200 nursing students, third-eighth semester, at a nursing faculty from 1 January to 30 July 2019 at Zanjan university of medical sciences, Iran. The students were included though census. Confidence interval of 95% and a significance level of Pvalue less than 0.05 was considered significant. Results and Conclusion The mean age of the students was 22 years. This study showed that the level of educational behaviours of clinical trainers had a direct correlation with the score of learning motivation subscale of students. It also had a direct significant correlation with the total score motivation toward science learning (p=0.01). The behaviours of clinical trainers and understanding of nursing students about the characteristics of trainers are important in creating motivation, facilitating learning, and improving nursing education.
