Balloon dilation therapy under direct endoscopic vision was performed in three patients with esophageal achalasia. The Rigiflex through-the-scope balloon dilator, with a maximum diameter of 10-25 mm, was used for dilatation, with a 10-min inflation period. In all patients, dysphagia and regurgitation improved, body weight increased, and esophagography revealed a decrease in esophageal diameter. Our approach differs from standard methods used in Europe and America, in that the balloon has a smaller diameter and the duration of inflation is longer. Although our balloon dilator was small caliber, satisfactory results were obtained because of the longer duration of inflation. We conclude that balloon dilatation is the first choice for treatment of esophageal achalasia, and that to increase the safety of this technique, it is necessary to begin such treatment with a small caliber balloon under direct endoscopic vision.

Subglottic stenosis poses a rare but life-threatening risk for difficult tracheal intubation. Here, we report a unique case of undiagnosed subglottic stenosis discovered during emergency intubation of an 80-year-old woman with type 2 respiratory failure from infective exacerbation of asthma. A small calibre size 5.

Synthetic vascular grafts are promising conduits for small caliber arteries. However, due to restenosis caused by intimal hyperplasia, they cannot keep long patency in vivo. In this work, through single cell RNA sequencing, we found that thrombospondin-1 (THBS1) was highly expressed in the regenerated smooth muscle cells (SMCs) in electrospun polycaprolactone (PCL) vascular grafts.

Optimal blood flow through a patent cerebral circulation is critical for supply of oxygen and nutrients for brain function. The integrity of vascular elements within arterial vessels of any calibre can be compromised by various disease processes. Pathological changes in the walls of veins and the venous system may also alter the dynamics of cerebral perfusion.

Patients And Methods: Materials and Methods: Endotheliocytes of the arterial and venous bed of the left and right testes of 60 white male rats, which were divided into two groups, were morphologically studied. The 1 group consisted of 30 intact animals, the 2 - 30 rats, which were daily intragastrically injected with a 30 % ethanol solution at the rate of 2 ml per 100 g of the animal's weight for 28 days.

The corpus callosum (CC) is the most important interhemispheric white matter (WM) structure composed of several anatomically and functionally distinct WM tracts. Resolving these tracts is a challenge since the callosum appears relatively homogenous in conventional structural imaging. Commonly used callosal parcellation methods such as Hofer and Frahm scheme rely on rigid geometric guidelines to separate the substructures that are limited to consider individual variation.
