A cross-validation of the Welsh origence-intelligence keys for the strong vocational interest blank

The purpose of the present study was to cross-validate Welsh's keys for scoring the Strong Vocational Interest Blank for Men. Welsh hypothesizes that the keys will identify and predict a subject's relative standing, high (Hi) or low (Lo), on the dimensions of origence (O), or creativity, and intelligence (I). Independent measures of origence and intelligence were obtained on 117 Ss, and on the basis of these measures Ss were identified as being in one of four quadrant combinations, Lo O, Lo I; Hi O, Lo I; Lo O, Hi I; or Hi O, Hi I. A chi-square analysis of the agreement between the Ss' independent measures (relative standing on O and I) and their placement on the Welsh-Strong keys in one of the four quadrants was significantly different from chance (. 05 level) for the Lo O, Lo I, and Hi O, Lo I combinations. A binomial test also showed significant agreement ( p < . 01) for the Hi O, Hi I combination. No results could be reported for the key which identifies Lo O, Hi I Ss as there were no Ss assigned to that quadrant by the independent measures. Also, it should be noted that an N of 7 for the Hi O, Hi I Ss is too small to determine validity. The results of the present study do indicate, however, that the keys have some concurrent validity and suggest that the study warrants replication

Some aspects of the effects of day care on infants' emotional and personality development

There is general agreement among theorists that the infant-mother relationship, or attachment, significantly affects the emotional and personality development of the young child. Separation of the infant from his mother which interferes with or dilutes this relationship is believed to have serious developmental consequences. There is concern about brief separations which infants today are experiencing in day care settings. It is important to determine if there are differences in emotional and personality development of infants in day care that might be a function of their being separated from their mother for eight to ten hours a day, five days a week, and cared for by a number of caregivers

Changes in characteristics of hospitalized heart failure patients in ten years: a single-center study

SummaryBackgroundProgress in therapy and the ageing patients hospitalized with heart failure may have impacted the characteristics of this patients.AimsWe compared epidemiological data of patients admitted with heart failure during two periods separated by a 10 year interval.MethodsCharacteristics of 353 heart failure patients recruited between 2002 and 2004 with those of 304 heart failure patients recruited between 1992 and 1994 were compared retrospectively.ResultsThere is now a majority of male patients (56.4%) not found ten years ago. The average age is unchanged (75.1±11 then 76.4±11 years) even though the proportion of patients aged over 70 years has increased (75% versus 70%). Hospital length of stay has fallen from 14±9 to 10±7 days. Hospital mortality (8%) are identical. The two main etiologies remain coronary and hypertensive heart disease at 29 and 24% respectively but these proportions are lower than ten years ago (42 and 28% respectively). The ejection fraction is more often preserved (56%) than before (44%). Increased prescription of inhibitors of the renin-angiotensin system and beta-blockers is confirmed. Post-hospital and total mortality has fallen by 50 and 30% from 30 to 16% and 35 to 24% respectively at the expense of a 25% increase in the frequency of hospital readmissions from 29 to 38%.ConclusionEven if mortality has declined, heart failure remains a major public health burden with a significant number of hospital readmissions. Other approaches such as therapeutic education must therefore be developed

Lumbar and ventricular CSF concentrations of extracellular matrix proteins before and after shunt surgery in idiopathic normal pressure hydrocephalus

Background: Idiopathic normal pressure hydrocephalus (iNPH) is a reversible CNS disease characterized by disturbed cerebrospinal fluid (CSF) dynamics. Changes in the extracellular matrix (ECM) composition might be involved in the pathophysiology of iNPH. The aim of this study was to explore possible differences between lumbar and ventricular CSF concentrations of the ECM markers brevican and neurocan, matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinase-1 (TIMP-1) and their relation to clinical symptoms in iNPH patients before and after shunt surgery. Methods: Paired lumbar and ventricular CSF was collected from 31 iNPH patients, before and four months after shunt surgery. CSF was analysed for concentrations of tryptic peptides originating from brevican and neurocan using a mass spectrometry-based panel, and for MMP-1, -2, -9, -10 and TIMP-1 using fluorescent or electrochemiluminescent immunoassays. Results: Brevican and neurocan peptide levels were not influenced by CSF origin, but MMP-1, -2, -10 and TIMP-1 were increased (p ≤ 0.0005), and MMP-9 decreased (p ≤ 0.0003) in lumbar CSF compared with ventricular CSF. There was a general trend of ECM proteins to increase following shunt surgery. Ventricular TIMP-1 was inversely correlated with overall symptoms (rho = − 0.62, p < 0.0001). CSF concentrations of the majority of brevican and neurocan peptides were increased in iNPH patients with a history of cardiovascular disease (p ≤ 0.001, AUC = 0.84–0.94) compared with those without. Conclusion: Levels of the CNS-specific proteins brevican and neurocan did not differ between the lumbar and ventricular CSF, whereas the increase of several CNS-unspecific MMPs and TIMP-1 in lumbar CSF suggests contribution from peripheral tissues. The increase of ECM proteins in CSF following shunt surgery could indicate disturbed ECM dynamics in iNPH that are restored by restitution of CSF dynamics

Dynamics of cerebrospinal fluid levels of matrix metalloproteinases in human traumatic brain injury

Matrix metalloproteinases (MMPs) are extracellular enzymes involved in the degradation of extracellular matrix (ECM) proteins. Increased expression of MMPs have been described in traumatic brain injury (TBI) and may contribute to additional tissue injury and blood–brain barrier damage. The objectives of this study were to determine longitudinal changes in cerebrospinal fluid (CSF) concentrations of MMPs after acute TBI and in relation to clinical outcomes, with patients with idiopathic normal pressure hydrocephalus (iNPH) serving as a contrast group. The study included 33 TBI patients with ventricular CSF serially sampled, and 38 iNPH patients in the contrast group. Magnetic bead-based immunoassays were utilized to measure the concentrations of eight MMPs in ventricular human CSF. CSF concentrations of MMP-1, MMP-3 and MMP-10 were increased in TBI patients (at baseline) compared with the iNPH group (p < 0.001), while MMP-2, MMP-9 and MMP-12 did not differ between the groups. MMP-1, MMP-3 and MMP-10 concentrations decreased with time after trauma (p = 0.001–0.04). Increased concentrations of MMP-2 and MMP-10 in CSF at baseline were associated with an unfavourable TBI outcome (p = 0.002–0.02). Observed variable pattern of changes in MMP concentrations indicates that specific MMPs serve different roles in the pathophysiology following TBI, and are in turn associated with clinical outcomes

How clusters create shared value in rural areas: An examination of six case studies

The main aim of this paper is to demonstrate that clusters can support the sustainable development of rural areas through the creation of shared value. This is done via the close examination of six different cases of rural clusters in Greece, Italy, Germany, Poland, Denmark, and Sweden. Qualitative as well as quantitative data were taken from the clusters, which demonstrated that their main business approaches naturally coincided with the creation of economic, social, and environmental benefits for the local communities in which they operated. The case clusters were created in a top-down manner, aimed at boosting regional R&amp;D activities and making the local economy more competitive and more sustainable. However, private initiative took over and al-lowed these clusters to flourish because meeting the regions’ economic, social, and environmental needs successfully coincided with the target of the clusters’ own development and profitability. The results show that clusters, with their potential for shared value creation, can constitute a powerful engine for the revitalisation and development of rural areas, addressing the significant challenges which they are currently facing

Development of fluorescent probes for bioimaging applications

Fluorescent probes, which allow visualization of cations such as Ca2+, Zn2+ etc., small biomolecules such as nitric oxide (NO) or enzyme activities in living cells by means of fluorescence microscopy, have become indispensable tools for clarifying functions in biological systems. This review deals with the general principles for the design of bioimaging fluorescent probes by modulating the fluorescence properties of fluorophores, employing mechanisms such as acceptor-excited Photoinduced electron Transfer (a-PeT), donor-excited Photoinduced electron Transfer (d-PeT), and spirocyclization, which have been established by our group. The a-PeT and d-PeT mechanisms are widely applicable for the design of bioimaging probes based on many fluorophores and the spirocyclization process is also expected to be useful as a fluorescence off/on switching mechanism. Fluorescence modulation mechanisms are essential for the rational design of novel fluorescence probes for target molecules. Based on these mechanisms, we have developed more than fifty bioimaging probes, of which fourteen are commercially available. The review also describes some applications of the probes developed by our group to in vitro and in vivo systems
