- Objectives: At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. Methods: Data were collected in four laboratories with a total of 20 males and 20 females performing a grand total of 1655 exposures. Each touched polished blocks of aluminium, stainless steel, nylon-6 and wood using the distal phalanx of the index finger with a contact force of 1.0, 2.9 and 9.8 N, at surface temperatures from +2 to -40 degrees C for a maximum duration of 120 s. Conditions were selected in order to elicit varying rates of skin cooling upon contact. Contact temperature (T-C) of the fingertip was measured over time using a T-type thermocouple. Results: A database obtained from the experiments was collated and analysed to characterize fingertip contact cooling across a range of materials and surface temperatures. The database was subsequently used to develop a predictive model to describe the contact duration required for skin contact temperature to reach the physiological criteria of onset of pain (15 degrees C), onset of numbness (7 degrees C) and onset of frostbite risk (0 degrees C). Conclusions: The data reflect the strong link between the risk of skin damage and the thermal properties of the material touched. For aluminium and steel, skin temperatures of 0 degrees C occurs within 2-6 s at surface temperatures of -15 degrees C. For non-metallic surfaces, onset of numbness occurs within 15-65 s of contact at -35 degrees C and onset of cold pain occurs within 5 s of contact at -20 degrees C. The predictive model subsequently developed was a non-linear exponential expression also reflecting the effects of material thermal properties and initial temperature. This model provides information for the protection of workers against the risk of cold injury by establishing the temperature limits of cold touchable surfaces for a broad range of materials, and it is now proposed as guidance values in a new international standard.

Statement by Members of the Task Force on Prevention and Public Health of the European Association for the Study of Obesity (EASO)

Tidskriftsartikel (refereegranskat)abstract
- This document is signed by all members of the task force, who will contribute knowledge on the problem of obesity in the various regions of Europe. It is apparent from the wide range of available prevalence estimates that the magnitude of the obesity epidemic varies across Europe. However certain similarities are present, including consistent but varying increases in prevalence in all countries from the end of the 20th century to the present, together with clear inverse socioeconomic gradients. The lack of harmonized surveillance efforts across Europe makes international monitoring and comparative assessments imprecise at best. A particularly worrisome aspect of this epidemic is the recently observed increase in the proportion of European children with overweight and obesity. The Task Force is in agreement that the epidemic reflects changing lifestyles and environments and that prevention can only be achieved by identifying and arresting these trends, a statement that has been repeated by many groups advocating obesity prevention over the years. For instance, in 1999 the Milan Declaration was made on behalf of all members of the EASO, resolving to support the development of coherent national and Europe-wide strategies for the prevention and management of overweight and obesity. Since then, there have been recent steps to develop a public health strategy for obesity prevention across Europe, including most notably the 2006 European Ministerial Conference on Counteracting Obesity in the European Region. At that time, all member states of WHO Europe met in Istanbul and explicitly agreed on an ecological approach to fighting the obesity epidemic, with a charter recognizing that counteracting obesity requires a multidisciplinary effort with a timeline for improvements (www.euro.who.int/ document/E89567.pdf). In this context, the vision of our Task Force is to provide guidance and leadership to researchers, governments, and agencies that are trying to fulfill the charter developed in Istanbul and other recent initiatives. Specifically, we will support and strengthen research and interventions to improve prevention of obesity across Europe, within the framework of the EASO.

Lifetime measurements of the negative-parity 7(-) and 8(-) states in Cd-122

- The Advanced Time-Delayed beta gamma gamma(t) method was used to measure lifetimes of selected high-spin states in Cd-122 populated from beta(-) decay of the J(pi)=(9(-)) isomer in Ag-122. From the gamma gamma coincidences, a new energy level was established at 2616.6 keV with a suggested spin-parity assignment of 8(-). Lifetimes were determined for the high-spin states at 2616.6 and 2502.7 keV as T-1/2=1.35(29) ns and 0.24(6) ns, respectively. The transition rates for gamma rays de-exciting the 7(-) states in the N=74 isotones of Cd-122, Sn-124, and Te-126 were found to be very similar.

VEGF-B is dispensable for blood vessel growth but critical for their survival, and VEGF-B targeting inhibits pathological angiogenesis
- 2009

- VEGF-B, a homolog of VEGF discovered a long time ago, has not been considered an important target in antiangiogenic therapy. Instead, it has received little attention from the field. In this study, using different animal models and multiple types of vascular cells, we revealed that although VEGF-B is dispensable for blood vessel growth, it is critical for their survival. Importantly, the survival effect of VEGF-B is not only on vascular endothelial cells, but also on pericytes, smooth muscle cells, and vascular stem/progenitor cells. In vivo, VEGF-B targeting inhibited both choroidal and retinal neovascularization. Mechanistically, we found that the vascular survival effect of VEGF-B is achieved by regulating the expression of many vascular prosurvival genes via both NP-1 and VEGFR-1. Our work thus indicates that the function of VEGF-B in the vascular system is to act as a "survival," rather than an "angiogenic" factor and that VEGF-B inhibition may offer new therapeutic opportunities to treat neovascular diseases.
