The repercussions of the economic crisis have been severe upon the foundations of the Greek economy and society, and the margins for future development are more than ever strict and urgent. Within an economically turbulent period, agriculture's role is reexamined and is called to play an enhanced role, particularly the livestock sector that comprises a key growth element for the economy, bearing in mind the number of people and industries employed in the production and processing of dairy products. ...

Lung well-to-moderately differentiated neuroendocrine tumors (also known as carcinoids) and large cell neuroendocrine lung carcinoma (poorly differentiated neuroendocrine tumor) are rare neuroendocrine neoplasms, which account for less than 4% of all lung neoplasms. Due to their low incidence, their systemic treatment is greatly influenced by therapeutic evidence derived from the more frequent gastroenteropancreatic neuroendocrine neoplasms and/or small cell lung carcinoma leading to significant bias. ...

Transhumance sheep and goat production have been a common and traditional practice in Greece, with its origins dating back to ancient times. Despite the diminishing number of transhumance farms, it remains an essential activity in less-favoured and mountainous areas of the country. This article applies DEA (Data Envelopment Analysis) in a sample of transhumance farms in Greece in order to assess the technical efficiency of sheep and goat transhumance flocks and determine the factors that affect their ...

A non-parametric data envelopment analysis (DEA) technique was applied to investigate the degree of technical and scale efficiency of commercial pig farming in Greece. Mean pure technical efficiency in a DEA model in which all variables were normalized with the number of sows was 0.83, indicating that there is ample potential for more efficient input utilisation in domestic pig farming. The normalized measurement of variables captures the fact that most scale-inefficient farms are operating under ...

In any turbulent economic environment, sectors of economic activity behave and resist differently depending on the causes of the turbulence. Some sectors present a unique resistance in economic aberrations, have a resilient attitude and play the role of the stabilizer, supporting growth and employment. Such sectors are usually related with people basic needs; in the current economic crisis, the agriculture and food sector stand out. The present study endeavours to examine the potentials of agriculture ...

Desmoplastic small round-cell tumour is a very rare neoplasm, which usually arises from the abdominal or pelvic peritoneum of adolescents and young adults. Early diagnosis is difficult, because most tumours present with non-specific gastrointestinal symptoms after a long asymptomatic period. It is generally a very aggressive tumour, which grows rapidly with poor prognosis and an overall five-year survival rate of 15% despite multimodal treatment. Despite multiple treatment strategies, the management ...

Small cell lung cancer (SCLC) remains one of the most lethal malignancies and a major health riddle. The therapeutic options are limited. The combination of etoposide or irinotecan with platinum chemotherapy is the standard of care at any stage. The last decade systemic efforts have been done to reveal specific therapeutic targets for small cell lung carcinomas. In this review, we focus on the new therapeutic strategies of SCLC, including immune-related treatment that may change the prognosis of ...

Low-molecular-weight heparins (LMWHs) and direct oral anticoagulants (DOACs) are among the current treatment options for cancer-associated thrombosis (CAT). We assessed real world data (RWD) regarding treatment patterns of CAT from 1 September 2018 to 31 January 2020. Recent findings RWD showed that LMWHs were the most common initial anticoagulation treatment for CAT. Based ...

We therefore investigated the incidence of latent EBV infection in a group of patients with leukemic low-grade B-NHL, as well as the incidence of viral latent membrane protein 1 (LMP1) oncoprotein expression in the same patient group. Furthermore, in an attempt to elucidate the role of this viral oncoprotein in non-EBV-related lymphomas, we correlated the ...
