Seleção de plantas em lavouras de café conilon no sul do Espírito Santo.
As lavouras de Conilon do Sul do Espírito Santo apresentam grande variabilidade genética, ainda não explorada nos trabalhos de melhoramento da Empresa Capixaba de Pesquisa, Assistência Técnica e Extensão Rural ? EMCAPER. O presente trabalho objetivou identificar plantas de café Conilon, com alta produção e qualidade de grãos na região Sul, para inclusão nos ensaios de competição com vistas a recomendação de novas variedades para os produtores capixabas. No primeiro ano foram selecionadas 391 plantas com bom potencial produtivo, tamanho do grão e uniformidade de maturação
Piezoelectric actuators for bone mechanical stimulation: exploring the concept.
Arthroplasty is liable to cause intense changes on strain levels and distribution in the boné surrounding the implant, namely stress shielding. Several solutions have been proposed for this, namely design variations and development of controlled-stiffness implants. A new approach to this problem, with potential application to other orthopaedic problems and other medical fields, would be the development of smart implants integrating systems for bone mechanical stimulation. Ideally, the implant should presente sensing capability and the ability to maintain physiological levels of strain at the implant interface. Piezoelectric materials’ huge potential as a mean to produce direct mechanical stimulation lies on the possibility of producing stimuli at a high range of frequencies and in multiple combinations. The present in vitro and preliminary in vivo studies were a first step towards the validation of the concept

Non-Small Cell Lung Cancer: Screening, Diagnosis, and Staging
Lung cancer is the leading cause of cancer deaths worldwide. Tobacco consumption is the primary cause of lung cancer, accounting
for more than 85% 90% of all lung cancer deaths. Non-small cell lung cancer accounts for about 85% of all lung cancers.
Several studies have shown that low-dose helical CT of the lung detects more nodules and lung cancers, including early-stage cancers,
than does chest radiography. The National Lung Cancer Screening Trial results show that three annual rounds of low-dose CT screening
reduce mortality from lung cancer. Despite the great debate around lung cancer screening, recently the National Comprehensive Cancer
Network has come out in favor of lung cancer screening in an updated set of guidelines.
All patients who present with suspect lung cancer should have a complete and meticulous history and physical examination performed
to identify symptoms or physical findings suggestive of locally extensive or metastatic disease, assess pulmonary health status, identify
significant comorbidities, and assess overall health status.
Tissue sampling is required to confirm a diagnosis in all patients with suspected lung cancer. Non-surgical approaches, surgical
approaches, or both may be used to obtain a tissue sample. Evaluation of the mediastinal lymph nodes is a key step in the further staging
of the patient. The best way of evaluating mediastinal lymph nodes is still a matter of debate.
The tumor node metastasis (TNM) International Staging System provides useful prognostic information and is used to stage all patients
with non-small cell lung cancer.
Recent trials added new data on screening and diagnostic approach. Those data will be reviewed in this paper
