The Impact of Experience with a Family Member with Alzheimer's Disease on Views about the Disease across Five Countries

The objective of this paper is to understand how the public's beliefs in five countries may change as more families have direct experience with Alzheimer's disease. The data are derived from a questionnaire survey conducted by telephone (landline and cell) with 2678 randomly selected adults in France, Germany, Poland, Spain, and the United States. The paper analyzes the beliefs and anticipated behavior of those in each country who report having had a family member with Alzheimer's disease versus those who do not. In one or more countries, differences were found between the two groups in their concern about getting Alzheimer's disease, knowledge that the disease is fatal, awareness of certain symptoms, and support for increased public spending. The results suggest that as more people have experience with a family member who has Alzheimer's disease, the public will generally become more concerned about Alzheimer's disease and more likely to recognize that Alzheimer's disease is a fatal disease. The findings suggest that other beliefs may only be affected if there are future major educational campaigns about the disease. The publics in individual countries, with differing cultures and health systems, are likely to respond in different ways as more families have experience with Alzheimer's disease

New trends in peptide-based anti-biofilm strategies : a review of recent achievements and bioinformatics approaches

Antimicrobial peptides (AMPs) have a broad spectrum of activity and unspecific mechanisms of action. Therefore, they are seen as valid alternatives to overcome clinically relevant biofilms and reduce the chance of acquired resistance. This paper reviews AMPs and anti-biofilm AMP-based strategies and discusses ongoing and future work. Recent studies report successful AMP-based prophylactic and therapeutic strategies, several databases catalogue AMP information and analysis tools, and novel bioinformatics tools are supporting AMP discovery and design. However, most AMP studies are performed with planktonic cultures, and most studies on sessile cells test AMPs on growing rather than mature biofilms. Promising preliminary synergistic studies have to be consubstantiated and the study of functionalized coatings with AMPs must be further explored. Standardized operating protocols, to enforce the repeatability and reproducibility of AMP anti-biofilm tests, and automated means of screening and processing the ever-expanding literature are still missing.Financial support from IBB-CEB and Fundacao para a Ciencia e Tecnologia (FCT) and European Community fund FEDER, through Program COMPETE, in the ambit of the FCT project 'PTDC/SAU-SAP/113196/2009/ FCOMP-01-0124-FEDER-016012' is gratefully acknowledged

Support for UNRWA's survival

The United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) provides life-saving humanitarian aid for 5·4 million Palestine refugees now entering their eighth decade of statelessness and conflict. About a third of Palestine refugees still live in 58 recognised camps. UNRWA operates 702 schools and 144 health centres, some of which are affected by the ongoing humanitarian disasters in Syria and the Gaza Strip. It has dramatically reduced the prevalence of infectious diseases, mortality, and illiteracy. Its social services include rebuilding infrastructure and homes that have been destroyed by conflict and providing cash assistance and micro-finance loans for Palestinians whose rights are curtailed and who are denied the right of return to their homeland

New technologies for examining neuronal ensembles in drug addiction and fear

Correlational data suggest that learned associations are encoded within neuronal ensembles. However, it has been difficult to prove that neuronal ensembles mediate learned behaviours because traditional pharmacological and lesion methods, and even newer cell type-specific methods, affect both activated and non-activated neurons. Additionally, previous studies on synaptic and molecular alterations induced by learning did not distinguish between behaviourally activated and non-activated neurons. Here, we describe three new approaches—Daun02 inactivation, FACS sorting of activated neurons and c-fos-GFP transgenic rats — that have been used to selectively target and study activated neuronal ensembles in models of conditioned drug effects and relapse. We also describe two new tools — c-fos-tTA mice and inactivation of CREB-overexpressing neurons — that have been used to study the role of neuronal ensembles in conditioned fear

Cue Reactivity in Active Pathological, Abstinent Pathological, and Regular Gamblers

Twenty-one treatment-seeking pathological gamblers, 21 pathological gamblers in recovery, and 21 recreational gamblers watched two video-taped exciting gambling scenarios and an exciting roller-coaster control scenario while their arousal (heart rate and subjective excitement) and urge to gamble were being measured. The gamblers did not differ significantly in cue-elicited heart rate elevations or excitement. However, the active pathological gamblers reported significantly greater urges to gamble across all cues compared to the abstinent pathological gamblers and, with marginal significance (p = 0.06), also compared to the social gamblers. Further exploration of these findings revealed that active pathological gamblers experience urges to gamble in response to exciting situations, whether or not they are gambling related, whereas abstinent and social gamblers only report urges to an exciting gambling-related cue. This suggests that for pathological gamblers excitement itself, irrespective of its source, may become a conditioned stimulus capable of triggering gambling behavior. Implications for treatment and future research are discussed

Effects of morphine and nalorphine upon tooth pulp thresholds of dogs in the alert and drowsy state

The alteration of tooth pulp thresholds of dogs with chronically implanted electrodes was determined in the awake and drowsy states after morphine and nalorphine. The elevation in tooth pulp threshold was significantly greater after morphine than during the alert or drowsy state of the animal. Nalorphine antagonized this effect of morphine.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46329/1/213_2004_Article_BF00441191.pd

Continuing the conversation about public health ethics: education for public health professionals in Europe

An important related question is why we should teach public health ethics. Fundamentally, we must teach public health ethics because ethical practice creates and maintains public trust and public health cannot function without public trust. To serve the public—whether through controlling an outbreak of an infectious disease, preparing for or responding to public health emergencies, or reducing the impact of non-communicable diseases—communities and individuals must trust our decisions and actions. This trust grows in large part from past successes, transparent and participatory decision making, and ethical management of the inevitable moral tensions that arise in our work.S

Self-administration of psychoactive substances by the monkey

A method has been developed which permits monkeys to self-administer drug solutions, at will, through indwelling intravenous catheters. Psychological dependence on the effects of a drug occurs when a naive monkey voluntarily initiates and maintains self-administration of the drug. If, in addition to psychological dependence, the drug also produces psychotoxicity, either directly or upon abrupt withdrawal, it has a potential abuse liability.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46354/1/213_2004_Article_BF00405254.pd
