Increased threat of metals simultaneous to the biota well-being and the environs is continually causing a major apprehension worldwide. The phytoremediation technique is highly advantageous involving the natural processes of plants viz., translocation, evapotranspiration, and bioaccumulation, thus degrading contaminants slowly. In particular, nanophytoremediation is a rapid green alternative as it reduces the ancillary impacts of the environment such as green gas emissions, waste generation, and natural resource consumption to the present scenario as there is a great potential of nanoparticles from plants which can be synthesized. Nanophytoremediation is a current methodology for remediation of pollutants, contaminants by using synthesized nanoparticles from plants. In this, the use of different strategies enhances the selective uptake capabilities of plants. The metal elements in excess are affecting the physiological processes in plants; thus, it is necessary to apply nanophytoremediation technology through transgenic plants. In this review paper, we focused on plant species, which can be used as metal tolerant, hyperaccumulators. Due to the insurmountable pressure of a sustainable cleaner environment, bioremediation can be concurrent with nanoparticles for efficient and effective sustainable measures.

Abstract Although families embrace the opportunity to care for a loved one, caregiving is stressful and takes a toll on the caregiver’s health and well-being. Earlier studies of stress and coping among family caregivers focused on psychological outcomes and emotional well-being. In the last decade, stress researchers have broadened their focus to include biomarkers and health outcomes. Data from two studies of caregivers of persons with memory loss will be used to discuss two new frontiers of caregiving research. First, a daily-diary study will be used to identify the mechanism by which stress disrupts the physiological processes and proliferates into serious psychopathology and pre-clinical and clinical health conditions. Second, a mindfulness-based psychoeducational intervention study will be utilized to identify malleable factors that can be harnessed to lower stress and improve the well-being of family caregivers. Next steps for caregiving research in the context of demographic and technological trends will be discussed.

Silico Analysis

Background Silicon (Si) is categorized as a quasi-essential element for plants thanks to the benefits on growth, development and metabolism in a hormetic manner. Si uptake is cooperatively mediated by Lsi1 and Lsi2. Nevertheless, Lsi channels have not yet been identified and characterized in pepper (Capsicum annuum), while genes involved in major physiological processes in pepper are Si-regulated. Furthermore, Si and phytohormones may act together in regulating plant growth, metabolism and tolerance against stress. Our aim was to identify potential synergies between Si and phytohormones stimulating growth and metabolism in pepper, based on in silico data. Methods We established a hydroponic system to test the effect of Si (0, 60, 125 and 250 mg L−1 Si) on the concentrations of this element in different pepper plant tissues. We also performed an in silico analysis of putative Lsi genes from pepper and other species, including tomato (Solanum lycopersicum), potato (Solanum tuberosum) and Arabidopsis thaliana, to look for cis-acting elements responsive to phytohormones in their promoter regions. With the Lsi1 and Lsi2 protein sequences from various plant species, we performed a phylogenetic analysis. Taking into consideration the Lsi genes retrieved from tomato, potato and Arabidopsis, an expression profiling analysis in different plant tissues was carried out. Expression of Si-regulated genes was also analyzed in response to phytohormones and different plant tissues and developmental stages in Arabidopsis. Results Si concentrations in plant tissues exhibited the following gradient: roots > stems > leaves. We were able to identify 16 Lsi1 and three Lsi2 genes in silico in the pepper genome, while putative Lsi homologs were also found in other plant species. They were mainly expressed in root tissues in the genomes analyzed. Both Lsi and Si-regulated genes displayed cis-acting elements responsive to diverse phytohormones. In Arabidopsis, Si-regulated genes were transcriptionally active in most tissues analyzed, though at different expressed levels. From the set of Si-responsive genes, the NOCS2 gene was highly expressed in germinated seeds, whereas RABH1B, and RBCS-1A, were moderately expressed in developed flowers. All genes analyzed showed responsiveness to phytohormones and phytohormone precursors. Conclusion Pepper root cells are capable of absorbing Si, but small amounts of this element are transported to the upper parts of the plant. We could identify putative Si influx (Lsi1) and efflux (Lsi2) channels that potentially participate in the absorption and transport of Si, since they are mainly expressed in roots. Both Lsi and Si-regulated genes exhibit cis-regulatory elements in their promoter regions, which are involved in phytohormone responses, pointing to a potential connection among Si, phytohormones, plant growth, and other vital physiological processes triggered by Si in pepper.

Objective To analyze the factors associated with health-related quality of life (HRQoL) in women with cervical cancer (CC) in a single center in Rio de Janeiro, state of Rio de Janeiro, Brazil. Methods A cross-sectional study in women with a diagnosis of CC followed-up in the gynecology outpatient clinic of the Hospital do Câncer II (HCII, in the Portuguese acronym) of the Instituto Nacional de Câncer (INCA, in the Portuguese acronym). The data were collected from March to August 2015. Women with palliative care, communication/cognition difficulty, undergoing simultaneous treatment for other types of cancer, or undergoing chemotherapy and/or radiation therapy were excluded. For the evaluation of the HRQoL, a specific questionnaire for women with CC was used (Functional Assessment of Cancer Therapy – Cervix Cancer [FACT-Cx]). The total score of the questionnaire ranges from 0 to 168, with higher scores indicating a better HRQoL. Results A total of 115 women were included in the present study, with a mean age of 52.64 years old (standard deviation [SD] = 12.13). The domains of emotional (16.61; SD = 4.55) and functional well-being (17.63; SD = 6.15) were those which presented the worst scores. The factors that had an association with better HRQoL in women with CC were having a current occupation, a longer time since the treatment and diagnosis, and women who had undergone hysterectomy. Conclusion Considering the domains of HRQoL of the women treated for cervical cancer, a better score was observed in the domains of physical and social/family well-being. For most domains, better scores were found between those with a current occupation, with a longer time after the diagnosis and treatment, and among those who had undergone a hysterectomy.

AbstractContrary to the bio-medical sciences most philosophers of medicine regard disease as an evaluative concept. C. Boorse’s well- known naturalist attempt to conceptualize disease exclusively on the basis of physiological fact seems highly plausible at first sight, since on this Supposition it is possible to make use of the impressive explanatory knowledge of modern medicine. But critical examination of his meta- physiological notion of “disease” as subnormal functioning shows that it does not conform to licensed medical disease-judgements. Furthermore his doctrine seems unjustified since it’s empirical implementability is highly questionable. This suggests that medicine is a naturalist enterprise that is guided by evaluation. An alternative conception of disease is advanced that tries to make the ‘nexus’ of physiological fact and evaluation intelligible: Disease is (extensionally) the class of physiological processes that (actually or prospectively) undermine the physiological conditions of human well-being.

Purpose The purpose of this paper is to examine the extent to which a systematic review approach is transferable from medicine to multi-disciplinary studies in the built environment research. Design/methodology/approach Primarily a review paper, it focuses on specific steps in the systematic review to clarify and elaborate the elements for adapting an evidence base in the built environment studies particular to the impact of green building on employees’ health, well-being and productivity. Findings While research represents a potentially powerful means of reducing the gap between research and practice by applying tried and tested methods, the methodological rigour is debatable when a traditional systematic review approach is applied in the built environment studies involving multi-disciplinary research. Research limitations/implications The foundational contribution of this paper lies in providing methodological guidance and an alternative framework to advance the longstanding efforts in the built environment to bridge the practitioner and academic divide. Originality/value A systematic review approach in the built environment is rare. The method is unique in multi-disciplinary studies especially in green building studies. This paper adopts the systematic review protocols in this cross-disciplinary study involving health, management and built environment expertise.

The purpose of this study was to explore the potential influence of childhood financial socialization on financial well-being in adulthood. Using a sample (N = 2,213) from De Nederlandsche Bank Household Survey (DHS) we modeled the likelihood of household debt/asset ratio less than or equal to 40%, and the likelihood of a household reporting a current ratio (liquid asset /short-term debt ratio) greater than or equal to 100%. Consistent with predictions of social learning theory, being encouraged to save during childhood had a positive association with meeting the financial planning industry benchmarks for these financial ratios in adulthood. The key implication is that the path to financial well-being does not begin with financial knowledge attained in adulthood, but instead begins with experiential learning and socialization during childhood.
