Influence of Storage Temperature on Radiochemical Purity of 99mTc-Radiopharmaceuticals
The influence of effective room temperature on the radiochemical purity of
99mTc-radiopharmaceuticals was reported. This study was born from the observation that in
the isolators used for the preparation of the 99mTc-radiopharmaceuticals the temperatures can
be higher than those reported in the commercial illustrative leaflets of the kits. This is due,
in particular, to the small size of the work area, the presence of instruments for heating, the continuous
activation of air filtration, in addition to the fact that the environment of the isolator used for the
99mTc-radiopharmaceuticals preparation and storage is completely isolated and not conditioned.
A total of 244 99mTc-radiopharmaceutical preparations (seven different types) have been tested
and the radiochemical purity was checked at the end of preparation and until the expiry time.
Moreover, we found that the mean temperature into the isolator was significantly higher than 25 C,
the temperature, in general, required for the preparation and storage of 99mTc-radiopharmaceuticals.
Results confirmed the radiochemical stability of radiopharmaceutical products. However, as required
in the field of quality assurance, the impact that different conditions than those required by the
manufacturer on the radiopharmaceuticals quality have to be verified before human administration
Medical students, spirituality and religiosity-results from the multicenter study SBRAME
Background: To evaluate the relationship between spirituality/religiosity (S/R) and the attitudes, beliefs and experiences of medical students in Brazil with respect to S/R in their undergraduate training and clinical practice.Methods: SBRAME (Spirituality and Brazilian Medical Education) is a multicenter study involving 12 Brazilian medical schools with 5950 medical students (MS). Participants completed a questionnaire that collected information on socio-demographic data and S/R in their undergraduate training and practice.Results: of all MS, 3630 participated in the survey (61.0%). the sample was 53.8% women and the mean age was 22.5 years. the majority of MS believed that spirituality has an impact on patients' health (71.2%) and that this impact was positive (68.2%). the majority also wanted to address S/R in their clinical practice (58.0%) and considered it relevant (75.3%), although nearly one-half (48.7%) felt unprepared to do so. Concerning their training, most MS reported that they had never participated in a spirituality and health activity (81.0%) and that their medical instructors had never or rarely addressed this issue (78.3%). the majority also believed that they should be prepared to address spiritual issues related to the health of their patients (61.6%) and that this content should be included in the medical curriculum (62.6%).Conclusion: There is a large gap between MS attitudes and expectations and the S/R training that they are receiving during their undergraduate training. the majority of MS surveyed believe that patients should have their beliefs addressed and that these beliefs could have important effects on their health and the doctor-patient relationship. These results should stimulate discussion about the place that S/R training should have in the medical curriculum.Univ Fed Juiz de Fora, Juiz de Fora, BrazilBrazilian Med Spiritist Assoc, São Paulo, BrazilUniversidade Federal de São Paulo, São Paulo, BrazilDuke Univ, Med Ctr, Durham, NC USAKing Abdulaziz Univ, Jeddah 21413, Saudi ArabiaUniversidade Federal de São Paulo, São Paulo, BrazilWeb of Scienc
Toward an Epigenetic View of Our Musical Mind
We are transient beings, in a world of constantly changing culture. At home in the fields of Art and Science, seemingly capable of magnificent abstractions, humans have an intense need to externalize their insights. Music is an art and a highly transmissible cultural product, but we still have an incomplete understanding of how our musical experience shapes and is vividly retained within our brain, and how it affects our behavior. However, the developing field of social epigenetics is now helping us to describe how communication and emotion, prime hallmarks of music, can be linked to a transmissible, biochemical change
L’adenocarcinoma dell’appendice ileo-ciecale: presentazione di un caso clinico e revisione della letteratura
L’adenocarcinoma dell’appendice ileo-ciecale è una neoplasia di rara osservazione rappresentando meno dello 0,5% di tutti i tumori dell’apparato gastrointestinale. Nella maggior parte dei casi viene diagnosticato all’esame istologico definitivo di un’appendice asportata per
flogosi, talora invece rappresenta un reperto del tutto inatteso, documentato da biopsie estemporanee, in corso di intervento chirurgico eseguito per sospetta appendicite acuta o altra patologia non appendicolare. La storia naturale di tale neoplasia è fortemente condizionata
dalle peculiari caratteristiche anatomiche del viscere che ne favoriscono la precoce diffusione e una notevole tendenza alla perforazione. Si
associa frequentemente ad altre neoplasie primitive, sincrone o metacrone, a localizzazione colo-rettale o extraintestinale.
Il trattamento chirurgico oncologicamente corretto è l’emicolectomia destra che può essere eseguita come prima procedura, nei casi in
cui la neoplasia venga diagnosticata pre- o intraoperatoriamente, o come seconda procedura, due-tre settimane dopo l’appendicectomia, qualora soltanto l’esame istologico dell’appendice asportata riveli la presenza dell’adenocarcinoma. L’emicolectomia destra è il trattamento chirurgico più idoneo in tutti gli istotipi (colico, mucinoso, adenocarcinoide), in presenza di perforazione ed anche nelle neoplasie allo stadio
A di Dukes. Durante l’atto operatorio è necessario effettuare un’accurata esplorazione della cavità addominale per la ricerca di neoplasie
sincrone, mentre dopo l’intervento i pazienti dovranno essere sottoposti ad un follow-up regolare e prolungato nel tempo onde diagnosticare precocemente eventuali neoplasie metacrone.
Riportiamo il caso di una donna di 78 anni con adenocarcinoma dell’appendice scoperto casualmente in corso di intervento chirurgico eseguito per un quadro di occlusione intestinale da sospetta neoplasia

Fruit wastes as a valuable source of value-added compounds: a collaborative perspective
The by-products/wastes from agro-food and in particular the fruit industry represents from one side an issue since they cannot be disposed as such for their impact on the environment but they need to be treated as a waste. However, on the other side, they are a source of bioactive healthy useful compounds which can be recovered and be the starting material for other products in the view of sustainability and a circular economy addressing the global goal of zero waste in the environment. An updated view of the state of art of the research on fruit wastes is here given under this perspective. The topic is defined as follows: (i) literature quantitative analysis of fruit waste/by-products, with particular regards to linkage with health; (ii) an updated view of conventional and innovative extraction procedures; (iii) high-value added compounds obtained from fruit waste and associated biological properties; (iv) fruit wastes presence and relevance in updated databases. Nowadays, the investigation of the main components and related bioactivities of fruit wastes is being continuously explored throughout integrated and multidisciplinary approaches towards the exploitation of emerging fields of application which may allow to create economic, environmental, and social value in the design of an eco-friendly approach of the fruit wastes.info:eu-repo/semantics/publishedVersio
