High-Sensitivity Seismometer Development for Lunar Applications.

Lunar seismology is a critical area of research, providing insights into the Moon's internal structure, composition, and thermal history, as well as informing the design of safe and resilient habitats for future human settlements. This paper presents the development of a state-of-the-art, three-axis broadband seismometer with a low-frequency range of 0.001-1 Hz and a target sensitivity over one order of magnitude greater than previous Apollo-era instruments.

A metastatic colon cancer model using nonoperative transanal rectal injection.

Background: This study aimed to develop a noninvasive orthotopic model for metastasis of colon and rectal cancer using a transanal approach. Currently, the most accurate orthotopic representation of metastatic human colon cancer is via a cecal injection. The transanal model allows for further examination of systemic immune responses, tumor take, and onset of metastasis without prior surgical intervention.

Prospective comparison of laparoscopic vs. open resections for colorectal adenocarcinoma over a ten-year period.

Purpose: The aim of this study was to define the long-term oncologic outcomes of laparoscopic resections for colorectal cancer.

Methods: We analyzed our experience via a prospective, nonrandomized, longitudinal cohort study. The period of study extended from April 1991 to May 2001.
