Exhaled breath barbotage: a new method for pulmonary surfactant dysfunction assessment [PDF]

open access: yes, 2017
Exhaled air contains aerosol of submicron droplets of the alveolar lining fluid (ALF), which are generated in the small airways of a human lung. Since the exhaled particles are micro-samples of the ALF, their trapping opens up an opportunity to collect non-invasively a native material from respiratory tract.

Selective parenchymal clamping in open partial nephrectomy: Early experience with a low cost, reusable novel parenchymal clamp

open access: yesBJUI Compass, Volume 4, Issue 1, Page 88-95, January 2023., 2023
Abstract Objectives The objective of this study is to present our initial experience with a novel parenchymal clamp (NPC) developed to allow partial nephrectomies (PN) to be performed without whole kidney ischaemia. We compare patients who underwent PN with the NPC with those undergoing standard PNs. Methods The NPC applies pressure only to the portion

A Multiscale Framework for Defining Homeostasis in Distal Vascular Trees: Applications to the Pulmonary Circulation [PDF]

open access: yesarXiv, 2020
Coupling hemodynamics with vessel wall growth and remodeling (G&R) is crucial for understanding pathology at distal vasculature to study progression of incurable vascular diseases, such as pulmonary arterial hypertension. The present study is the first modeling attempt that focuses on defining homeostatic baseline values in distal pulmonary vascular ...

Comparison of outcomes following lobectomy, segmentectomy, and wedge resection based on pathological subtyping in patients with pN0 invasive lung adenocarcinoma ≤1 cm

open access: yesCancer Medicine, Volume 11, Issue 24, Page 4784-4795, December 2022., 2022
For patients with invasive adenocarcinoma 1cm in whom anatomical resection is not feasible, wedge resection could provide similar oncological effect when tumor is lepidic predominant or acinar predominant. Abstract Purpose We sought to analyze the prognostic significance of lung adenocarcinoma classification for patients with pathological N0 (pN0) lung
