Stone Pine (Pinus pinea L.) High-Added-Value Genetics: An Overview.

Stone pine (Pinus pinea L.) has received limited attention in terms of genetic research. However, genomic techniques hold promise for decoding the stone pine genome and contributing to developing a more resilient bioeconomy. Retrotransposon and specific genetic markers are effective tools for determining population-specific genomic diversity. Studies on the transcriptome and proteome have identified differentially expressed genes PAS1, CLV1, ATAF1, and ACBF involved in shoot bud formation. The stone pine proteome shows variation among populations and shows the industrial potential of the enzyme pinosylvin. Microsatellite studies have revealed low levels of polymorphism and a unique genetic diversity in stone pine, which may contribute to its environmental adaptation. Transcriptomic and proteomic analyses uncover the genetic and molecular responses of stone pine to fungal infections and nematode infestations, elucidating the defense activation, gene regulation, and the potential role of terpenes in pathogen resistance. Transcriptomics associated with carbohydrate metabolism, dehydrins, and transcription factors show promise as targets for improving stone pine's drought stress response and water retention capabilities. Stone pine presents itself as an important model tree for studying climate change adaptation due to its characteristics. While knowledge gaps exist, stone pine's genetic resources hold significant potential, and ongoing advancements in techniques offer prospects for future exploration.

Microbiological Assessment of White Button Mushrooms with an Edible Film Coating.

The development of edible coatings incorporating bioextracts from mushrooms native to Portuguese forests aims to enhance the value of the endogenous forest and mycological resources by harnessing their potential as a source of antimicrobial and antioxidant compounds. Edible coatings represent an important pathway to decreasing food waste and contributing to implementing a circular bioeconomy. The coating should result in product valorization through improved preservation/conservation, increased shelf life, as well as enhancement of its antioxidant and enzymatic properties. To evaluate the effectiveness of an edible coating on fungal food matrices, a 14-day shelf-life study was conducted, wherein both coated and untreated mushrooms were examined under controlled storage temperatures of 4 °C and 9.3 °C. Agaricus bisporus was chosen as the food matrix for its bioeconomy significance, and Pleurotus eryngii was selected for the preparation of the food-based coating due to its profile of bioactive compounds. Microbiological analysis and physicochemical monitoring were conducted on the food matrices and the coating. Coated mushrooms had less mass loss and color change, and had better texture after 14 days. Microbiological analysis revealed that the coating had no antimicrobial activity. Overall, the coating improved the shelf life of the coated mushrooms but had less effect on the microbial community.

Acalculous acute cholecystitis during the course of an enteroviral infection.

Gallbladder diseases are uncommon in children. Acalculous acute cholecystitis, although rare, is the most frequent form of acute cholecystitis in childhood. In acalculous acute cholecystitis, clinical presentation and laboratory findings are unspecific, making the diagnosis challenging. Abdominal ultrasonography is the first-line exam. Most cases of paediatric acalculous acute cholecystitis have been described in critically ill patients, but can occur in previously healthy children, without underlying diseases or severe conditions. The authors present a clinical report of a child with acalculous acute cholecystitis and enteroviral infection. Diagnosis, treatment, clinical course and prognosis are described. Pathophysiology, aetiology, diagnosis and treatment of acalculous acute cholecystitis are also discussed.

[Coronary artery bypass after Kawasaki disease]. / Cirurgia de revascularização coronária após doença de Kawasaki.

Kawasaki disease (KD) is a systemic vasculitis of unknown etiology, which is the main cause of acquired heart disease in children in developed countries. The main complications result from the development of coronary aneurysms which can lead to ischemic heart disease. We present the case of a teenage boy with a diagnosis of KD at the age of seven. He was treated with gammaglobulin and aspirin and echocardiographic evaluation in the acute phase was apparently normal. At the age of eleven, he developed chest pain and exertional dyspnea. Nuclear perfusion scans with exercise revealed hypoperfusion of the left anterior descending (LAD) and right coronary (RC) artery territories. Cardiac catheterization showed occlusion of the proximal segments of both arteries. He underwent coronary artery bypass graft surgery (internal mammary artery bypass graft to the LAD artery and saphenous vein graft to the RC artery), with a good clinical result. This case report highlights the importance of early diagnosis and treatment of KD and regular cardiological follow-up, bearing in mind the potential late complications of this pediatric disease.

[Sickle cell disease and cerebrovascular stroke: a preventable event]. / Anemia de células falciformes e acidente vascular cerebral: uma história evitável.

INTRODUCTION: About 75% of the children presenting with cerebrovascular stroke have an identified cause. For black children, the most common underlying condition is sickle cell disease. This case report describes a preventable natural history, with an unusual presenting feature. CASE PRESENTATION: 27th month black infant without relevant background, presented with an acute focal neurological deficit. Brain computed tomography scan showed extensive acute infarction, and magnetic resonance also revealed previous silent cerebral infarct. Blood sample showed normocytic anemia and spontaneous sickling of the red blood cells, with 87% hemoglobin S. Exchange transfusion was made. CONCLUSION: Stroke, as a sickle cell disease complication, can occur at early ages and being the presenting sign. We consider that it would be worth spread the antenatal hemoglobinopathy screening programme, and evaluating the cost-effectiveness of a neonatal screening programme for sickle cell disease in Portugal.
