The prevalence of obesity is rising progressively, even among older age groups. By the year 2030-2035 over 20% of the adult US population and over 25% of the Europeans will be aged 65 years and older. The predicted prevalence of obesity in Americans, 60 years and older was 37% in 2010. The predicted prevalence of obesity in Europe in 2015 varies between 20 and 30% dependent on the model used. This means 20.9 million obese 60+ people in the USA in 2010 and 32 million obese elders in 2015 in the EU. Although cut-off values of BMI, waist circumference and percentages of fat mass have not been defined for the elderly (nor for the elderly of different ethnicity), it is clear from several meta-analyses that mortality and morbidity associated with overweight and obesity only increases at a BMI above 30 kg/m(2). Thus, treatment should only be offered to patients who are obese rather than overweight and who also have functional impairments, metabolic complications or obesity-related diseases, that can benefit from weight loss. The weight loss therapy should aim to minimize muscle and bone loss but also vigilance as regards the development of sarcopenic obesity - a combination of an unhealthy excess of body fat with a detrimental loss of muscle and fat-free mass including bone - is important in the elderly, who are vulnerable to this outcome. Life-style intervention should be the first step and consists of a diet with a 500 kcal (2.1 MJ) energy deficit and an adequate intake of protein of high biological quality together with calcium and vitamin D, behavioural therapy and multi-component exercise. Multi-component exercise includes flexibility training, balance training, aerobic exercise and resistance training. The adherence rate in most studies is around 75%. Knowledge of constraints and modulators of physical inactivity should be of help to engage the elderly in physical activity. The role of pharmacotherapy and bariatric surgery in the elderly is largely unknown as in most studies people aged 65 years and older have been excluded.

BACKGROUND: The reverse transcription quantitative real-time polymerase chain reaction (RT-qPCR) is a widely used, highly sensitive laboratory technique to rapidly and easily detect, identify and quantify gene expression. Reliable RT-qPCR data necessitates accurate normalization with validated control genes (reference genes) whose expression is constant in all studied conditions. This stability has to be demonstrated.We performed a literature search for studies using quantitative or semi-quantitative PCR in the rat spared nerve injury (SNI) model of neuropathic pain to verify whether any reference genes had previously been validated. We then analyzed the stability over time of 7 commonly used reference genes in the nervous system - specifically in the spinal cord dorsal horn and the dorsal root ganglion (DRG). These were: Actin beta (Actb), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ribosomal proteins 18S (18S), L13a (RPL13a) and L29 (RPL29), hypoxanthine phosphoribosyltransferase 1 (HPRT1) and hydroxymethylbilane synthase (HMBS). We compared the candidate genes and established a stability ranking using the geNorm algorithm. Finally, we assessed the number of reference genes necessary for accurate normalization in this neuropathic pain model. RESULTS: We found GAPDH, HMBS, Actb, HPRT1 and 18S cited as reference genes in literature on studies using the SNI model. Only HPRT1 and 18S had been once previously demonstrated as stable in RT-qPCR arrays. All the genes tested in this study, using the geNorm algorithm, presented gene stability values (M-value) acceptable enough for them to qualify as potential reference genes in both DRG and spinal cord. Using the coefficient of variation, 18S failed the 50% cut-off with a value of 61% in the DRG. The two most stable genes in the dorsal horn were RPL29 and RPL13a; in the DRG they were HPRT1 and Actb. Using a 0.15 cut-off for pairwise variations we found that any pair of stable reference gene was sufficient for the normalization process. CONCLUSIONS: In the rat SNI model, we validated and ranked Actb, RPL29, RPL13a, HMBS, GAPDH, HPRT1 and 18S as good reference genes in the spinal cord. In the DRG, 18S did not fulfill stability criteria. The combination of any two stable reference genes was sufficient to provide an accurate normalization.

A 4 de Maio de 1512, D. Manuel I, rei de Portugal, fez mercê do ofício de almoxarife da vila da Ribeira Grande a Álvaro Dias, escudeiro de Sua Casa e morador da ilha de Santiago. A 20 de Fevereiro de 1534, D. João III confirmou a dita carta. 2 Durante o período que medeia entre estas duas datas decorre a vivência administrativa de uma das personagens mais interessantes e representativas da ilha de Santiago na primeira metade do século XVI. Esta figura, que foi ao mesmo tempo oficial régio, armador e mercador, representou como almoxarife os interesses da Fazenda Real na vila da Ribeira Grande. Como morador de Santiago, que armava navios e comerciava com a costa da Guiné, pertencia à camada social dominante da ilha. Pelo facto de colocar os seus negócios acima dos deveres que tinha perante a Coroa, Álvaro Dias foi por várias vezes destituído do ofício. No entanto, aproveitando-se das fraquezas existentes nas estruturas da administração, conseguiu reter, até à sua morte, a carta de almoxarife.

Este trabalho mostra que a contabilidade pode não estar a evidenciar o real valor do património das empresas (um dos seus objectivos), constatamos nos últimos tempos, que os relatórios fornecidos pela contabilidade financeira não retratam certas realidades das empresas, visto que o valor contabilístico se distancia cada vez mais do valor de mercado, principalmente nas empresas de alta tecnologia e serviços, assim sendo as demonstrações financeiras podem estar experimentando uma perda de relevância para a tomada de decisões de investimentos, de crédito e de gestão. Dentro deste contexto, ressaltamos a necessidade de a contabilidade evidenciar naquelas demonstrações tais informações para que possa divulgar aos vários utentes da informação o real valor da empresa. Visto que o Capital Intelectual é importante para as empresas, torna-se necessário relatar não só informações financeiras como também não financeiras. Este trabalho apresenta um estudo descritivo/quantitativo da empresa CVTelecom, com o objectivo de avaliar o grau de divulgação do Capital Intelectual na empresa. A principal constatação foi o seguinte: uma participação activa da empresa em divulgar o Capital Intelectual, uma forma não normalizada através da divulgação voluntária do Capital Intelectual cujo veículo de divulgação, é o Relatório de Gestão e o Balanço Social. This work shows that the Accounting cannot be evidencing the Real value of the patrimony of the enterprises (one of their objectives), we verified in the last times, that the reports supplied by the Financial Accounting don't portray certain realities of the enterprises, because the value Accounting of the enterprises go away more and more of his market value, mainly in the companies of high technology and services, soon the financial demonstrations are trying a loss of relevance for socket of decisions of investments, of credit and of administration. Inside of this context, we emphasized the need of the Accounting to evidence in the demonstrations such financial information so that it can publish to the several users of the information the Real value of the company. Because the Intellectual Capital is important for the enterprises, it becomes necessary to tell not only financial information as well as any financial. This work presents a descriptive-quantitative study of the enterprise CVtelecom, with the objective of evaluating the degree of popularization of the Intellectual Capital in the enterprise and the impact in the performance of this enterprise. The main verification was the following: A participation active of the company in publishing the Intellectual Capital in spite of being in a way no normalized but a voluntary popularization of the Intellectual Capital, whose popularization vehicle is the Report of Administration and the Social Swinging.

We analyze the impact of countercyclical capital buffers held by banks on the supplyof credit to firms and their subsequent performance. Spain introduced dynamicprovisioning unrelated to specific bank loan losses in 2000 and modified its formulaparameters in 2005 and 2008. In each case, individual banks were impacteddifferently. The resultant bank-specific shocks to capital buffers, coupled withcomprehensive bank-, firm-, loan-, and loan application-level data, allow us toidentify its impact on the supply of credit and on real activity. Our estimates showthat countercyclical dynamic provisioning smooths cycles in the supply of credit andin bad times upholds firm financing and performance.

In this paper we propose a general technique to develop first and second order closed-form approximation formulas for short-time options withrandom strikes. Our method is based on Malliavin calculus techniques andallows us to obtain simple closed-form approximation formulas dependingon the derivative operator. The numerical analysis shows that these formulas are extremely accurate and improve some previous approaches ontwo-assets and three-assets spread options as Kirk's formula or the decomposition mehod presented in Alòs, Eydeland and Laurence (2011).

In this paper we study the dynamic behavior of the term structureof Interbank interest rates and the pricing of options on interest ratesensitive securities. We posit a generalized single factor model withjumps to take into account external influences in the market. Daily datais used to test for jump effects. Qualitative examination of the linkagebetween Monetary Authorities' interventions and jumps are studied. Pricingresults suggests a systematic underpricing in bonds and call options ifthe jumps component is not included. However, the pricing of put optionson bonds presents indeterminacies.

This note elaborates on a recent article by Chan, Greenbaum and Thakor(1992) who contend that fairly priced deposit insurance is incompatiblewithfree competition in the banking sector, in the presence of adverseselection.We show here that at soon as one introduces a real economic motivationfromprivate banks to manage the deposits from the public, then fairly priceddeposit insurance becomes possible. However, we also show that sucha fairlypriced insurance is never desirable, precisely because of adverseselection.We compute the characteristics of the optimal premium schedule, whichtradesoff between the cost of adverse selection and the cost of ``unfaircompetition ''.

Treatment of status epilepticus (SE) consists in the sequential administration of three lines of drugs. The first is represented by benzodiazepines, and enjoys quite robust scientific evidence. The second one includes (phos-) phenytoin, valproate, phenobarbital, and increasingly levetiracetam, but its rationale is relatively scarce. The third line is pharmacological coma induction with barbiturates, propofol, or midazolam, which lacks the support of prospective, controlled studies and is reserved for refractory SE. Several other drugs are used after failure of this scheme, including newer antiepileptic compounds, other medications, and non-pharmacological approaches; no comparative assessment of their respective role has been conducted. It is important to tailor this relatively simple protocol to each particular situation; the supposed advantages of coma induction should be balanced with the morbidity related to prolonged mechanical ventilation. Awide consensus exists to treat generalized-convulsive SE and SE in coma soon and aggressively, to prevent a dismal outcome. On the other side, it is unclear if complex-partial SE induces permanent neuronal damage, and absence SE has an excellent prognosis: it appears therefore advisable not to proceed automatically to coma induction in these cases. SE related to post-anoxic coma has generally a poor prognosis, but some selected cases seem to be amenable to a better outcome if treated. SE prognosis depends on etiology, the biological background including age and comorbidities, and, possibly, treatment; each of these points deserves to be specifically addressed. A simple prognostic score has been recently validated and, helping to orient early treatment strategies and improve SE management.

The aim of this paper is to examine the pros and cons of book and fair value accounting from the perspective of the theory of banking. We consider the implications of the two accounting methods in an overlapping generations environment. As observed by Allen and Gale(1997), in an overlapping generation model, banks have a role as intergenerational connectors as they allow for intertemporal smoothing. Our main result is that when dividends depend on profits, book value ex ante dominates fair value, as it provides better intertemporal smoothing. This is in contrast with the standard view that states that, fair value yields a better allocation as it reflects the real opportunity cost of assets. Banking regulation play an important role by providing the right incentives for banks to smooth intertemporal consumption whereas market discipline improves intratemporal efficiency.
