Bronchiectasis is a sequel to permanent chronic airway inflammation and defined as 'irreversible bronchial dilatation'. It is increasingly being recognized with the wider availability of high-resolution computed tomography. Children with noncystic fibrosis can be seen with improvement in bronchiectasis even resolution, as opposed to adults. We report a case of reversible bronchial dilatation in an adult as evidenced by high-resolution computed tomography, which demonstrates that, although quite rare in adults, spontaneous resolution may occur.

The human placenta exhibits a complex three-dimensional (3D) structure with a interpenetrating vascular tree and large internal interfacial area. In a unique and yet insufficiently explored way, this parenchymal structure enables its multiple functions as a respiratory, renal, and gastrointestinal multiorgan. The histopathological states are highly correlated with complications and health issues of mother, and fetus or newborn.

Background: Sublobar resection is suitable for peripheral stage I lung adenocarcinoma (LUAD). However, if tumor spread through air spaces (STAS) present, the lobectomy will be considered for a survival benefit. Therefore, STAS status guide peripheral stage I LUAD surgical approach.

A longstanding challenge in biology is accurately analyzing images acquired using microscopy. Recently, machine learning (ML) approaches have facilitated detailed quantification of images that were refractile to traditional computation methods. Here, we detail a method for measuring pigments in the complex-mosaic adult eye using high-resolution photographs and the pixel classifier [1].

Currently, the primary imaging methods used in clinical diagnosis are X-ray, computed tomography (CT), ultrasound, magnetic resonance imaging (MRI), PET-CT, etc. The sensitivity and accuracy of these imaging methods bring many difficulties in clinical diagnosis; at the same time, CT, X-ray, PET-CT, etc. can cause radiation to the human body; some invasive operations of the gold standard bring much pain to the patients.

Background: The use of advanced diagnostic methods, such as high-resolution CT or PET-CT scans, are limited in low and middle-income countries (LMICs). In gastric cancer, occult peritoneal disease may be present in up to 20% of cases, limiting the benefits of surgical resection. Accurate staging of gastric cancer is essential to ensure optimal patient management and prevent undue morbidity from unnecessary surgery.
