Myelodysplastic Syndrome With Synchronous Gastric Cancer: When The Symptoms Suggest Something Else.

Although myelodysplastic syndromes have a clear definition in theory, the morphologic dysplasia associated with ineffective hematopoiesis may be subtle and difficult to recognize and can commonly be mimicked by systemic conditions, such as infections, autoimmune disorders, nutritional deficiencies, toxic factors and non-hematological malignancies. However, myelodysplastic syndromes may truly coexist with other systemic diseases, which can be masked when the patient's symptoms are attributed exclusively to myelodysplastic syndromes without further investigation. To better illustrate this, we herein describe two cases associated with synchronous gastric cancers.

Honours students: good marks and what else?

Currently in Portugal academic excellence in higher education is given recognition through merit prizes. Because honours students can be seen as having the potential to achieve imporant levels of professional expertise, especially if they have some personal skills, it is important to know not only the marks of the students but also the personal characteristics that contribute to academic success and which may also be important for career success. Some theoretical models of giftedness and excellence agree with this idea and this work considers the latest contribution of Renzulli (2005) where it is pointed out that excellent achievements result from the combination of motivational, intellectual and creative factors as well as from co-cognitive factors which are most associated with personality functioning in a particular context. The main purpose of this paper is to analyze how honours students differ from their classmates in various psychological dimensions: Cognition-creativity, Motivation and Learning Strategies, Persistence, Social Interaction, Drive for Excellence and Cultural Interest. These dimensions were measured by the Inventory of Psychological Characteristics Associated with Academic Performance (ICPADA), which was constructed taking into consideration the previous study of Scaeger et al. (2012). The sample included 914 Portuguese higher educatoin students from a first cycle degree in the Bologna process. Participants were selected from three different fields of study: Social and Human Sciences; Science and Technology; Arts and Humanities. The data collected through the administration of the ICPADA was presented, and the results revealed a higher self-perception by honours students in all areas analyzed, with the exception of the dimension of social interaction. In addition an interaction effect was revealed for persistence, social interaction, and cultural interest. The field of study and whether the participants were honours students or not were also taken into account. Some implications for future studies are presented here along with possible interventions for honours students.

Dipeptidyl peptidase IV and its inhibitors: therapeutics for type 2 diabetes and what else?

The proline-specific dipeptidyl aminopeptidase IV (DPP IV, DPP-4, CD26), widely expressed in mammalians, releases X-Pro/Ala dipeptides from the N-terminus of peptides. DPP IV is responsible of the degradation of the incretin peptide hormones regulating blood glucose levels. Several families of DPP IV inhibitors have been synthesized and evaluated. Their positive effects on the degradation of the incretins and the control of blood glucose levels have been demonstrated in biological models and in clinical trials. Presently, several DPP IV inhibitors, the "gliptins", are approved for type 2 diabetes or are under clinical evaluation. However, the gliptins may also be of therapeutic interest for other diseases beyond the inhibition of incretin degradation. In this Perspective, the biological functions and potential substrates of DPP IV enzymes are reviewed and the characteristics of the DPP IV inhibitors are discussed in view of type 2 diabetes and further therapeutic interest.

Non-random fertilization in mice correlates with the MHC and something else

One evolutionary explanation for the success of sexual reproduction assumes that sex is an advantage in the coevolutionary arms race between pathogens and hosts. Accordingly, an important criterion in mate choice and maternal selection thereafter could be the allelic specificity at polymorphic loci involved in parasite-host interactions, e.g. the MHC (major histocompatibility complex). The MHC has been found to influence mate choice and selective abortions in mice and humans. However, it could also influence the fertilization process itself, i.e. (i) the oocyte's choice for the fertilizing sperm, and (ii) the outcome of the second meiotic division after the sperm has entered the egg. We tested both hypotheses in an in vitro fertilization experiment with two inbred mouse strains congenic for their MHC. The genotypes of the resulting blastocysts were determined by polymerase chain reaction. We found nonrandom MHC combinations in the blastocysts which may result from both possible choice mechanisms. The outcome changed significantly over time, indicating that a choice for MHC combinations during fertilization may be influenced by one or several external factors.

Crème Noisette. What else?

Segurament us sonarà aquest eslògan: Nespresso, What else? Café, cuerpo y alma. Segurament, si us mencionem a l’actor George Clooney, ja no només l’identifiqueu amb una de les seves pel·lícules, sinó que directament us ve laimatge de l’anunci que protagonitza per Nespresso. I fins i tot, segurament, molts dels que esteu llegint aquest text, no us heu pogut resistir a la temptació i ja disposeu d’una màquina Nespresso a casa vostra. Nespresso s’ha convertiten un fenomen de masses i en una de les empreses que més està creixent en aquests últims anys. Per tots aquests motius, a l’hora de triar quin seria l’eix fonamental del nostre treball, vam decantar-nos per aquesta empresa.El que pretenem amb aquest treball és esbrinar tots els passos que s’han de seguir per a llençar un nou producte al mercat i analitzar la importància que té el marketing per a les empreses d’avui dia. Hem emmarcat aquests dos objectius dins de l’empresa Nespresso, i és per això que portarem a terme el llançament d’una nova càpsula d’un gust original, analitzarem com serà el seu procés productiu i dissenyarem les possibles tècniques de promoció per tal que tingui èxit. Pel que fa al segon objectiu, comprovarem mitjançant un experiment el grau d’influència que té el marketing sobre els clients.Referent a les conclusions que hem extret amb el nostre treball, aquestes són, per una part, la creació de Crème Noisette, una nova càpsula que no us deixarà indiferents; i per l’altra, que Nespresso basa el seu èxit en la qualitat, però sempre acompanyada d’una gran campanya de marketing.Voleu continuar descobrint els secrets que amaga el llançament d’una nova càpsula? Voleu saber si la gent aprecia realment totes les varietats que ofereix Nespresso? Per a descobrir-ho, us convidem a llegir el nostre treball.
