Methods: 7,475 CT studies were selected from 17 cohorts containing CT images of untreated cancer patients who underwent follow-up for a period of 2.

Gender representation among speaking and leader roles at European cardio-thoracic surgical annual meetings.

Objectives: Our goal was to evaluate gender representation among session leaders and abstract presenters at European cardio-thoracic surgical annual meetings.

Methods: We did a descriptive study of the gender distribution among session leaders and abstract presenters at 2 European cardio-thoracic international meetings from 2017 to 2022. Data from publicly available programmes were used to generate a list of session leaders and abstract presenters.

Defining Optimal Settings for Lung Cryobiopsy in End-Stage Pulmonary Disease. A Human, Ex Vivo, Diseased Lung Clinical Trial.

Background: To evaluate optimal settings of probe size, freezing time, and distance to the pleura that influence the size and quality of biopsy specimens during transbronchial lung cryobiopsies in ESPD.

Methods: We prospectively recruited 17 patients undergoing lung transplantation. We created a nonperfused ex vivo bronchoscopy setting to perform multiple cryobiopsies with different probe sizes (1.

Effect of reduced water intake on ovarian reserve, leptin immunoexpression and impact of leptin on the in vitro culture of sheep secondary follicles.

This study evaluated the effect of reduced water intake on survival, apoptosis and immunoexpression of leptin in sheep preantral follicles, activation of primordial follicles, serum levels of leptin, estradiol (E2) and progesterone (P4), and in vitro maturation (IVM) of oocytes antral follicles, as well evaluated the effects of leptin on in vitro culture of secondary follicles isolated these animals. Ewes (n = 32) were divided into four groups: water ad libitum (Control - 100%), 80%; 60% and 40% of ad libitum intake. Blood was collected to determine, leptin, E2 and P4, before and after experiment.

Assessment of the developmental defects of the enamel in children and adolescents with sickle cell disease: A comparative study.

Background: Sickle cell disease (SCD) is the most important hemoglobinopathy in terms of frequency and social impact and can affect the stomatognathic system.

Aim: To assess and compare the developmental defects of the enamel (DDE) in children and adolescents with and without SCD.

Design: This was a cross-sectional, analytical, and comparative study of 210 children and adolescents aged 5-18 years, who visited the Hematology and Hemotherapy Hospital of Pernambuco.

Association between adolescents who are victims of bullying and weapon possession.

Objective: To verify the association between victims of bullying and weapon possession among school adolescents.

Methods: This cross-sectional study was carried out with 2,296 high school students aged 14-19 years. An instrument containing questions from the validated Youth Risk Behavior Survey questionnaire and the National School Health Survey was used.

Immunolocalization of melatonin receptor type 1 in the sheep ovary and involvement of the PI3K/Akt/FOXO3a signaling pathway in the effects of melatonin on survival and in vitro activation of primordial follicles.

This study characterized the expression of melatonin receptor type 1 (MT ) protein in sheep ovaries, evaluated melatonin effects on primordial follicle survival and development after in vitro culture of ovarian tissue and verified the possible involvement of the phosphatidylinositol-3-kinase/protein kinase B/forkhead box O3a (PI3K/Akt/FOXO3a) pathway in the melatonin actions. Ovine ovarian fragments were cultured in α-modified minimum essential medium alone (α-MEM ) or supplemented with 100, 500, or 1000 pg/ml melatonin for 7 days. PI3K inhibition was performed through pretreatment of ovarian fragments with LY294002.

Dry Season Transpiration and Soil Water Dynamics in the Central Amazon.

With current observations and future projections of more intense and frequent droughts in the tropics, understanding the impact that extensive dry periods may have on tree and ecosystem-level transpiration and concurrent carbon uptake has become increasingly important. Here, we investigate paired soil and tree water extraction dynamics in an old-growth upland forest in central Amazonia during the 2018 dry season. Tree water use was assessed via radial patterns of sap flow in eight dominant canopy trees, each a different species with a range in diameter, height, and wood density.
