Abstract
In the network of reactions present in the Big Bang nucleosynthesis, the 3He(n, p)3H has an important role which impacts the final 7Li abundance. The Trojan Horse Method (THM) has been applied to the 3He(d, pt)H reaction in order to extract the astrophysical S(E)-factor of the 3He(n, p)3H in the Gamow energy range. The experiment will be described in the present work together with the first preliminary results.

Abstract
Suicide rates have increased in Ireland's youth over the past two decades. However, no research report has focussed on suicide rates in those aged under 18--the children of Ireland. We retrieved national disaggregated age and sex-specific suicide mortality data from 1993-1998 and compared it with similar suicide mortality data from 2003-2008. Significant age (older vs younger) and sex effects (boys greater risk than girls) are apparent in both decades Suicide rates in both males and females have increased (males: 9.3-13.5/100,000), (females: 2.4-5.1/100,000. Suicide rates in under 15 year olds boys and girls is extremely rare for both time periods studied (1.6/100,000). Results are discussed in light of the rights of children and the obligation of the nation in this regard, as well as more child-specific and transition to adulthood-specific suicide prevention policy implications.

Abstract
Background The aim of this prospective study was to determine whether a level of positive airway pressure was generated in participants receiving nasal high flow (NHF) delivered by the Optiflow™ system (Fisher and Paykel Healthcare Ltd, Auckland, New Zealand) in a cardiothoracic and vascular intensive care unit (ICU). Methods Nasopharyngeal airway pressure was measured in 15 postoperative cardiac surgery adult patients who received both NHF and standard facemask therapy at a flow rate of 35 litre min−1. Measurements were repeated in the open mouth and closed mouth positions. Mean airway pressure was determined by averaging the pressures at the peak of inspiration of each breath within a 1 min period, allowing the entire pressure profile of each breath to be included within the calculation. Results Low level positive pressure was demonstrated with NHF at 35 litre min−1 with mouth closed when compared with a facemask. NHF generated a mean nasopharyngeal airway pressure of mean (sd) 2.7 (1.04) cm H2O with the mouth closed. Airway pressure was significantly higher when breathing with mouth closed compared with mouth open (P≤0.0001). Conclusions This study demonstrated that a low level of positive pressure was generated with NHF at 35 litre min−1 of gas flow. This is consistent with results obtained in healthy volunteers.

Abstract
This paper is an examination of how research ethics committees have evolved from being advisory committees to more formal regulatory authorities. It is argued that the role of ethics committees should be broader than simple ethical review. Inconsistency in outcome should not be taken to signal failure. Procedural fairness is of the utmost importance. Nor should ethics committees be seen to diminish the ethical responsibilities of researchers themselves.

Abstract
The purpose of this cross-sectional, descriptive study was to describe the relationships between learned helplessness and disease status, functional and social disability, and disease activity in the multiple sclerosis population. Additionally, the relationships between learned helplessness and age, disease duration, education and marital and employment status were evaluated. Self-report instruments with established validity and reliability in the multiple sclerosis population were used to collect the data. Learned helplessness was significantly positively correlated with social and functional disability. Although not significant at the .05 level, disease status and disease activity were also positively correlated with learned helplessness. Additionally, unemployed individuals were more likely to be helpless than employed individuals. Overall, the results suggest that learned helplessness is related to negative health indicators in the multiple sclerosis population. Nursing interventions to decrease or prevent learned helplessness may be appropriate in this population.

Abstract
Studies were performed to determine the mechanism underlying deficient arginine vasopressin (AVP)-stimulated adenylyl cyclase activity in chronic renal failure (CRF). As compared to control, principal cells cultured from the inner medullary collecting tubule of rats previously made uremic by 5/6 nephrectomy fail to accumulate cAMP when stimulated with AVP. CRF cells do respond normally to forskolin or cholera toxin and the defect in AVP responsiveness is not prevented by treatment with pertussis toxin, by cyclooxygenase inhibition, or by inhibition or down-regulation of protein kinase C. In contrast to their lack of responsiveness to AVP, CRF cells respond normally to other agonists of adenylyl cyclase such as isoproterenol or prostaglandin E2. Plasma membranes prepared from the inner medullae of CRF rats exhibit a marked decrease in apparent AVP receptor number but no change in the apparent number of beta adrenergic receptors. Reverse transcriptase PCR of total RNA from the inner medullae of CRF animals reveals virtual absence of V2 receptor mRNA; mRNA for alpha s is present in normal abundance. These studies indicate that AVP resistance in CRF is due, at least in part, to selective down-regulation of the V2 receptor as a consequence of decreased V2 receptor mRNA.

Abstract
Rat kidney slices were produced using a modified version of a mechanical tissue slicer. The slices were incubated with various concentrations of L-cysteine conjugates and mercapturic acids of halogenated alkenes in a submersion incubation system. The slices showed a time- and concentration-dependent toxicity to the nephrotoxic conjugates. The five L-cysteine conjugates tested: S-(1,2-dichlorovinyl)-L-cysteine (1,2-DCVC), S-(1,1,2,2-tetrafluoroethyl)-L-cysteine (TFEC), S-(1-chloro-1,2,2-trifluoroethyl)-L-cysteine (CTFEC), S-(1,1-dichloro-2,2-difluoroethyl)-L-cysteine (DCDFEC) and S-(1,1-dibromo-2,2-difluoroethyl)-L-cysteine (DBDFEC) were more toxic compared to the corresponding mercapturic acids. Comparing the in vitro toxicity data with the in vivo data for the same compounds results in similar ranking for the relative nephrotoxicity of the conjugates.
