Impact of CA9 expression in the diagnosis of lymph-node metastases in non-small cell lung cancer based on [18F]FDG PET/CT.

Background: Lung cancer is the leading cause of the global cancer incidence and mortality. It is important to obtain an accurate diagnosis of lymph-node metastasis before surgery to select the therapeutic strategy for non-small cell lung cancer (NSCLC) patients. Carbonic anhydrase 9 (CA9) is considered a marker of hypoxia and it has reported that CA9 is associated with tumor invasion and metastasis.

Right Ventricular-Pulmonary Arterial Coupling and Outcome in Heart Failure With Preserved Ejection Fraction.

Background: Right ventricular-pulmonary artery coupling (RVPAC) refers to the relationship between right ventricular systolic force and afterload. The ratio of echocardiograph-derived tricuspid annular plane systolic excursion (TAPSE) to pulmonary artery systolic pressure (PASP) has been proposed as a noninvasive measurement of RVPAC and reported as an independent prognostic parameter of heart failure. However, it has not been adequately in detail evaluated in heart failure with preserved ejection fraction (HFpEF).

Right Lower Sleeve Lobectomy: Detailed Technique and Perioperative Patient Management.

Purpose: This report reviews our experience with right lower sleeve lobectomy and describes our technique and approach to perioperative patient management.

Methods: We retrospectively reviewed 11 patients who underwent right lower sleeve lobectomy for lung cancer. Surgical techniques and perioperative management were also investigated.

[Factors and Mechanisms of Pleural Dissemination in Surgically Treated Cases of Lung Metastasis Originated from Pancreatic Cancer].

Pancreatic cancer with distant metastasis typically results in a poor prognosis, but patients with only pulmonary metastasis are reported to have a relatively good prognosis. In this study, we investigated the clinicopathological data and prognosis of 15 patients who underwent surgery for lung metastasis of pancreatic cancer at our hospital between April 2010 and December 2021. The median disease-free interval after pancreatic cancer treatment was 24.

Tracking Sugar-Elicited Local Searching Behavior in Drosophila.

Foraging behavior is essential for the survival of organisms as it enables them to locate and acquire essential food resources. In Drosophila, hunger triggers a distinct search behavior following the consumption of small quantities of a sugar solution. This report presents a simple experimental setup to study sugar-elicited search behavior with the aim of uncovering the underlying mechanisms.
