November 2024

Department of Microbiology, School of Preclinical Medicine, Air Force Medical University: Fourth Military Medical University, Xi'an, Shaanxi, 710032, China. Electronic address:

Article Synopsis
  • Hantavirus causes severe diseases with high mortality rates, and current treatments are lacking; however, Type I interferon has shown promise when administered early.
  • The study reveals that Hantaan virus (HTNV) increases the expression of the enzyme cholesterol 25-hydroxylase (CH25H), which then helps inhibit HTNV infection through cholesterol regulation.
  • It suggests that 25-hydroxycholesterol (25HC) and cholesterol-lowering statins could be repurposed as effective antiviral treatments against hantavirus infections, highlighting the potential of targeting cholesterol metabolism in developing new therapies.

We sequenced and genotyped severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza, adenovirus, and respiratory syncytial virus, among other pathogens, from residual anterior nasal swabs self-collected for rapid SARS-CoV-2 antigen testing at the US Naval Academy. This is a key proof-of-concept for an acute respiratory infection surveillance approach, which could leverage prevalent SARS-CoV-2 antigen self-testing.

A Baseline Model of PTSD From the ACES Cohort.

Mil Med

August 2024

59th Medical Wing/Science and Technology, Joint Base San Antonio-Lackland Air, Force Base, TX 78236, USA.

Introduction: Post-traumatic stress disorder (PTSD) is a primary military psychiatric condition with complex etiology including strong genetic and/or environmental influences. Environmental influences and demographics can play a role in supporting underlying genetic traits for clinical utility evaluation as risk modifying factors. We are undertaking an IRB approved study to evaluate polygenic scores of PTSD risk in the adverse childhood experience and serotonin (ACES) transporter cohort.

Article Synopsis
  • A total of 95 plasma samples were collected, with 68 from CRC patients and 27 from healthy controls, and high-throughput sequencing along with PCR was used to analyze miRNA expression.
  • The study found that miR-99b-5p and miR-409-3p were significantly elevated in CRC patients, especially in early stages, and a combination of these miRNAs with carcinoembryonic antigen showed improved diagnostic accuracy for early CRC detection.

Background: Academic libraries play a significant role in the student learning process. However, student needs and preferences as well as new paradigms of learning are driving libraries to transition from quiet book repositories to places of collaboration and open information. This descriptive, mixed methods case presentation explores the transition of one library, the United States Air Force School of Aerospace Medicine Franzello Aeromedical Library, in three key areas: collection, capability, and facility.

Efficacy and safety of variceal embolization for primary prophylaxis in cirrhosis patients with challenges in standard treatments: preliminary results.

Front Med (Lausanne)

July 2024

State Key Laboratory of Holistic Integrative Management of Gastrointestinal Cancers, National Clinical Research Center for Digestive Diseases and Xijing Hospital of Digestive Diseases, Air Force Medical University, Xi'an, Shaanxi, China.

Objectives: Nonselective beta blockers (NSBBs) or endoscopic therapies are currently recommended by guidelines for preventing the first variceal bleed in patients with high-risk varices. However, there is a lack of detailed treatment strategies for patients who are intolerant to both NSBBs and endoscopic approaches. Our study aimed to assess the efficacy and safety of variceal embolization as a primary prophylaxis method in cirrhosis patients who are not suitable candidates for NSBBs or endoscopic treatments.

Exposure to microgravity during spaceflight induces the alterations in endothelial cell function associated with post-flight cardiovascular deconditioning. PIEZO1 is a major mechanosensitive ion channel that regulates endothelial cell function. In this study, we used a two-dimensional clinostat to investigate the expression of PIEZO1 and its regulatory mechanism on human umbilical vein endothelial cells (HUVECs) under simulated microgravity.

A Nomogram to Predict Intracranial Hypertension in Moderate Traumatic Brain Injury Patients.

World Neurosurg

November 2024

Department of Neurosurgery, Tangdu Hospital, Air Force Medical University, Xi'an, China. Electronic address:

Objective: Patients with moderate traumatic brain injury (mTBI) are under the threat of intracranial hypertension (IHT). However, it is unclear which mTBI patient will develop IHT and should receive intracranial pressure (ICP)-lowering treatment or invasive ICP monitoring after admission. The purpose of the present study was to develop and validate a prediction model that estimates the risk of IHT in mTBI patients.

Renal cell carcinoma (RCC) is the most common malignant tumor in the urinary system, accounting for 80 % to 90 % for all renal malignancies. Traditional diagnostic methods like magnetic resonance imaging (MRI) and computed tomography (CT) lack the sensitivity and specificity as they lack specific biomarkers. These limitations impede effective monitoring of tumor recurrence.

Antigenic assessments of SARS-CoV-2 variants inform decisions to update COVID-19 vaccines. Primary infection sera are often used for assessments, but such sera are rare due to population immunity from SARS-CoV-2 infections and COVID-19 vaccinations. Here, we show that neutralization titers and breadth of matched human and hamster pre-Omicron variant primary infection sera correlate well and generate similar antigenic maps.

Exercise is usually regarded to have short-term beneficial effects on immune health. Here we show that early-life regular exercise exerts long-term beneficial effects on inflammatory immunity. Swimming training for 3 months in male mice starting from 1-month-old curbs cytokine response and mitigates sepsis when exposed to lipopolysaccharide challenge, even after an 11-month interval of detraining.
