Adopting the Future Consultation response document (MS Word 290 KB)

While for most children the best place to grow up is with their birth parents, others are unable to do so. Under the Children (Northern Ireland) Order 1995, the first duty of Health and Social Services Trusts, where children cannot live with their birth parents, is to seek a home for them with their extended famly. Finding a safe and caring new home for children with their wider family or friends allows them to keep important attachments and connections in their lives, and is therefore the preferred choice where it is possible. Where this is not possible, society has a clear responsibility to provide children with stability and permanence in their lives. Some children are placed in alternative forms of care. Adoption is traditionally a means of providing a permanent family for a small, but significant number of children who are unable to return to their birth parents. Adoption is, however, much wider than just the service provided to children. Adoption affects birth parents, prospective adopters, adoptive parents, siblings, grandparents and other relatives. The Department of Health Social Services and Public Safety believes that more can and should be done to reflect the complex needs of those affected by adoption. åÊ

Altruism across disciplines: one word, multiple meanings

Altruism is a deep and complex phenomenon that is analysed by scholars of various disciplines, including psychology, philosophy, biology, evolutionary anthropology and experimental economics. Much confusion arises in current literature because the term altruism covers variable concepts and processes across disciplines. Here we investigate the sense given to altruism when used in different fields and argumentative contexts. We argue that four distinct but related concepts need to be distinguished: (a) psychological altruism, the genuine motivation to improve others' interests and welfare; (b) reproductive altruism, which involves increasing others' chances of survival and reproduction at the actor's expense; (c) behavioural altruism, which involves bearing some cost in the interest of others; and (d) preference altruism, which is a preference for others' interests. We show how this conceptual clarification permits the identification of overstated claims that stem from an imprecise use of terminology. Distinguishing these four types of altruism will help to solve rhetorical conflicts that currently undermine the interdisciplinary debate about human altruism.

Using flow cytometry for in situ monitoring of antimicrobial compound production in the biocontrol bacterium Pseudomonas fluorescens CHA0.

Pseudomonas fluorescens strain CHA0 is able to protect plants against a variety of pathogens, notably by producing the two antimicrobial compounds 2,4-diacetylphloroglucinol (DAPG) and pyoluteorin (PLT). The regulation of the expression of these compounds is affected by many biotic factors, such as fungal pathogens, rhizosphere bacteria as well as plant species. Therefore, the influence of some plant phenolic compounds on the expression of DAPG and PLT biosynthetic genes has been tested using GFP-based reporter, monitored by standard fluometry and flow cytometry. In situ experiments were also performed with cucumber plants. We found that several plant metabolites such as IAA and umbelliferone are able to modify significantly the expression of DAPG and PLT. The use of flow cytometry with autofluorescents proteins seems to be a promising method to study rhizobacteria-plant interactions.

Targeting aquaporin function: potent inhibition of aquaglyceroporin-3 by a gold-based compound.

Aquaporins (AQPs) are membrane channels that conduct water and small solutes such as glycerol and are involved in many physiological functions. Aquaporin-based modulator drugs are predicted to be of broad potential utility in the treatment of several diseases. Until today few AQP inhibitors have been described as suitable candidates for clinical development. Here we report on the potent inhibition of AQP3 channels by gold(III) complexes screened on human red blood cells (hRBC) and AQP3-transfected PC12 cells by a stopped-flow method. Among the various metal compounds tested, Auphen is the most active on AQP3 (IC(50) = 0.8±0.08 µM in hRBC). Interestingly, the compound poorly affects the water permeability of AQP1. The mechanism of gold inhibition is related to the ability of Au(III) to interact with sulphydryls groups of proteins such as the thiolates of cysteine residues. Additional DFT and modeling studies on possible gold compound/AQP adducts provide a tentative description of the system at a molecular level. The mapping of the periplasmic surface of an homology model of human AQP3 evidenced the thiol group of Cys40 as a likely candidate for binding to gold(III) complexes. Moreover, the investigation of non-covalent binding of Au complexes by docking approaches revealed their preferential binding to AQP3 with respect to AQP1. The high selectivity and low concentration dependent inhibitory effect of Auphen (in the nanomolar range) together with its high water solubility makes the compound a suitable drug lead for future in vivo studies. These results may present novel metal-based scaffolds for AQP drug development.

Randomized observation periods for the compound Poisson risk model: Dividends

In the framework of the classical compound Poisson process in collective risk theory, we study a modification of the horizontal dividend barrier strategy by introducing random observation times at which dividends can be paid and ruin can be observed. This model contains both the continuous-time and the discrete-time risk model as a limit and represents a certain type of bridge between them which still enables the explicit calculation of moments of total discounted dividend payments until ruin. Numerical illustrations for several sets of parameters are given and the effect of random observation times on the performance of the dividend strategy is studied.

Late migration of percutaneous bio-absorbable devices--a word of caution.

BACKGROUND: Closures of atrial septal defects or a patent foramen ovale (PFO) are increasingly performed percutaneously. The experience of late migration of a new bio-absorbable device is presented here, followed by conceptual discussion. METHODS: Six months post PFO closure with a BioSTAR® device a patient presented with chest pain. Echocardiography showed a hyperechogenic structure perforating the aortic wall. RESULTS: Surgical exploration showed a perforation of the ascending aorta by one metallic, non absorbable arm. This is the second case of late (>6 months) dislocation of the residual framework of the occluder. CONCLUSIONS: The overall incidence of perforation of cardiac structures due to secondary dislocation is low. However this complication exists and should kept in mind in symptomatic patients with new onset of chest pain, after percutaneous procedures. The concept of biodegradation, with residual, non absorbable metal braiding, should be reviewed, analyzing in particular long term results and incidence of secondary dislocation.

Identification and Characterization of Natural Anti-Breast Cancer Compound: Costunolide

Breast cancer is the most common cancer among women, 23% (1.3 million) of the total of new cases and the second leading cause of cancer death in women exceeded only by lung cancer. Natural medicines have been proven to be a central source of narrative agents with a pharmaceutical potential. Costunolide is sesquiterpene lactones consisting of diverse plant chemicals that exhibit anti cancer action through cytotoxic effects on various cancer cells. The objectives of present study were to explore the effects of natural compounds on the proliferation of MCF-7 cells and to determine the role of ROS in natural compounds-induced apoptosis in breast cancer cells with a therapeutic potential. Results showed that costunolide screened, possess potent anticancer properties against breast cancer MCF-7 cells, Costunolide was observed as strong anti-proliferative agent with IC50 = 50µM. The anti-proliferative effect of costunolide on MCF cells was confirmed by live/dead assay using fluorescent probes calcein AV/PI. The results demonstrated that treatment of cells with costunolide decreased the viability of MCF-7 cells in a dose-dependent manner. To determine the costunolide-induced apoptosis, flow cytometric analysis was carried out. The results showed that costunolide induced apoptosis in a dose-dependent manner in breast cancer MCF-7cells. ROS are well known mediators of intracellular signaling of cascades. The excessive generation of ROS can induce oxidative stress, loss of cell functioning, and apoptosis. In the present study, we assumed that costunolide might arouse ROS level, which could be involved in induction of apoptosis. Therefore, the intracellular ROS level was measured using the ROS-detecting fluorescence dye 2, 7-dichlorofluorescein diacetate (DCF-DA). Interestingly these effects were significantly abrogated when the cells were pretreated with N-acetyl- cysteine (NAC), a specific ROS inhibitor. Costunolide induces apoptosis through extrinsic pathway in MCF-7 breast cancer cells, In order to examine whether costunolide suppresses cell growth inducing apoptotic cell death, we analyzed DNA contents and apoptosis-related proteins expression level by flow cytometry and western blot, respectively in MCF-7 breast cancer cells we investigated whether costunolide activates extrinsic apoptotic pathway. We examined the expression levels of death receptor signaling-related proteins, caspase-3, and PARP. The results showed that procaspase-3 was cleaved to yield 17 and 20kDa fragments and activation of PARP in treated cells with 25 and 50μM of costunolide. Costunolide induce apoptosis through intrinsic mitochondria pathway in MCF-7 breast cancer Cells. We examined the expression levels of mitochondrial apoptotic pathway related proteins such as anti-apoptotic protein, B-cell lymphoma protein-2 (Bcl2), and pro-apoptotic protein Bax. Costunolide involved in the down regulation of Bcl-2 and up regulation of Bax. These results suggest that costunolide may have beneficial effects for the reduction of breast cancer growth, and new therapeutic strategy for the treatment of human cancers.
