Thermal infrared image processing to assess heat generated by magnetic nanoparticles for hyperthermia applications

Magnetic fluid hyperthermia (MFH) is considered a promising therapeutic technique for the treatment of cancer cells, in which magnetic nanoparticles (MNPs) with superparamagnetic behavior generate mild-temperatures under an AC magnetic field to selectively destroy the abnormal cancer cells, in detriment of the healthy ones. However, the poor heating efficiency of most NMPs and the imprecise experimental determination of the temperature field during the treatment, are two of the majors drawbacks for its clinical advance. Thus, in this work, different MNPs were developed and tested under an AC magnetic field (~1.10 kA/m and 200 kHz), and the heat generated by them was assessed by an infrared camera. The resulting thermal images were processed in MATLAB after the thermographic calibration of the infrared camera. The results show the potential to use this thermal technique for the improvement and advance of MFH as a clinical therapy.

The continuing use of complementary and alternative medicine in South Australia: costs and beliefs in 2004

Objective: To survey the use, cost, beliefs and quality of life of users of complementary and alternative medicine (CAM). Design: A representative population survey conducted in 2004 with longitudinal comparison to similar 1993 and 2000 surveys. Participants: 3015 South Australian respondents over the age of 15 years (71.7% participation). Results: In 2004, CAMs were used by 52.2% of the population. Greatest use was in women aged 25-34 years, with higher income and education levels. CAM therapists had been visited by 26.5% of the population. In those with children, 29.9% administered CAMs to them and 17.5% of the children had visited CAM therapists. The total extrapolated cost in Australia of CAMs and CAM therapists in 2004 was AUD$1.8 billion, which was a decrease from AUD$2.3 billion in 2000. CAMs were used mostly to maintain general health. The users of CAM had lower quality-of-life scores than non-users. Among CAM users, 49.7% used conventional medicines on the same day and 57.2% did not report the use of CAMs to their doctor. About half of the respondents assumed that CAMs were independently tested by a government agency; of these, 74.8% believed they were tested for quality and safety, 21.8% for what they claimed, and 17.9% for efficacy. Conclusions: Australians continue to use high levels of CAMs and CAM therapists. The public is often unaware that CAMs are not tested by the Therapeutic Goods Administration for efficacy or safety.

The spatial pattern of discrete beta-amyloid deposits in Alzheimer's disease reflects synaptic disconnection

The spatial pattern of discrete beta-amyloid (A beta) deposits was studied in the superficial laminae of cortical fields of different types and in the hippocampus in 6 cases of Alzheimer's disease (AD). In 41/42 tissues examined, discrete A beta deposits were aggregated into clusters and in 34/41 tissues (25/34 of the cortical tissues), there was evidence for a regular periodicity of the A beta deposit clusters parallel to the tissue boundary. The dimensions of the clusters varied from 400 to > 12,800 microns in different tissues. Although the A beta deposit clusters were larger than predicted, the regular periodicity suggests that they develop in relation to groups of cells associated with specific projections. This would be consistent with the hypothesis that the distribution of discrete A beta deposits in AD could reflect progressive synaptic disconnection along interconnected neuronal pathways. This implies that amyloid deposition could be a response to, rather than a cause of, synaptic disconnection in AD.

A kiskereskedelmi stratégiai szövetségek hatása a kiskereskedelmi marketing tevékenységére és teljesítményére = Effects of the retail strategic alliances to the retailers' marketing activity and performance

A kilencvenes évek második felétől egyre jelentősebb szerepet játszanak a vállalatközi együttműködések, hosszabb távú kooperációk a hazai élelmiszer- és napi cikk kiskereskedelemben. A társulások szintjén a piaci siker egyértelmű, amely jól nyomon követhető az évente megjelenő kiskereskedői rangsorokban. A cikk viszont a tagkereskedők szemszögéből vizsgálja a kérdést, vajon a társuláshoz való csatlakozás ténylegesen javítja-e a kiskereskedő teljesítményét és milyen dimenziókon keresztül. _____________ From the second half of the ’90s the strategic alliances, the long term cooperations have been increasingly role in the domestic food and FMCG retail. On the level of the alliances the market success has been obvious, which has well presented in the annual retail rankings. The article examines the issue from the retailers’ point of view: whether the accession to the alliance has effectively improved the retalier’s performance and which dimensions through.

A társadalmi tőke egyes elemeinek hatása együttműködő dunántúli borászati vállalatok árpolitikájára

Napjainkban a vállalati együttműködések korábbiaknál erőteljesebb piaci jelenléte figyelhető meg a gazdaság számos területén, a stratégiai szövetségektől a beszállítói hálózatokon keresztül a klaszterekig. A piaci szereplők együttműködése versenyelőnyt biztosíthat, megkönnyítheti piaci térnyerésüket, továbbá a vállalati növekedést. Mind a nemzetközi, mind a magyar borágazat dinamikus átalakuláson megy keresztül, sorra jelennek meg a különféle vállalatközi együttműködések, kooperációk. A szerzők tanulmányukban feltárják a társadalmi tőke azon puha (soft) tényezőit, melyek révén a gazdasági szereplők hajlandóak összefogni, továbbá az együttműködés jellege szerint tipizálják és csoportosítják az együttműködésben részt vevő borászatokat. Ez a tipizálás segítséget nyújt a kooperáló borászati vállalatok árképzési politikájának mélyebb megismerésében.

Water temperature reconstructions based on paired Uk'37 and Tex86 records, and paired surface and subsurface Mg/Ca records

This dataset contains the collection of available published paired Uk'37 and Tex86 records spanning multi-millennial to multi-million year time scales, as well as a collection of Mg/Ca-derived temperatures measured in parallel on surface and subsurface dwelling foraminifera, both used in the analyses of Ho and Laepple, Nature Geoscience 2016. As the signal-to-noise ratios of proxy-derived Holocene temperatures are relatively low, we selected records that contain at least the last deglaciation (oldest sample >18kyr BP).

Ações de promoção em saúde bucal: um estudo com o povo indígena Tremembé, CE

Este trabalho aborda ações de promoção em saúde desenvolcidas no Projeto de Saúde Bucal com Povo Indígena Tremembé, Ceará, viabilizadas por uma parceria da Igreja Metodista, Universidade Federal do Rio Grande do Norte (UFRN) e Universidade Metodista de Piracicaba (UNIMEP). Pretendeu contribuir para a melhoria na qualidade da saúde bucal Tremembé valorizando etnoconhecimentos e saúde integral. A atuação priorizou Ações de Educação e Saúde utilizando um Levantamento Epidemiológico para o diagnóstico situacional de cárie e planejamento, e contemplou o Atendimento Odontológico. Nas Ações de Educação em Saúde utilizou-se a pedagogia da problematização através de Oficinas de Preservação em Saúde resultando na produção da Cartilha de Saúde Bucal Tremembé. Os dados epidemiológicos, com 102 indivíduos, obtidos através do índice CPO-D (dentes permanentes cariados, perdidos e obturados) foram organizados pelo programa Epi Info 6.04, em 4 grupos etários (até 24; 25-34; 35-44; 45›) resultando em médias que variaram de 9,5 a 20,9 respectivamente, evidenciando precária situação de saúde bucal. As ações de promoção em saúde contribuíram para consciência sanitária, no sentido da reivindicação dos direitos à saúde representada como um exercício da cidadania, bem como na busca pela autonomia em relação à prevenção de doenças bucais entre os Tremembé.
