Facile Labeling of Gram-Negative Bacteria with NIR-II Fluorescent Nanoprobes for Intestinal Bacteria Imaging.

The gut bacteria not only play a crucial role in maintaining human health but also exhibit close associations with the occurrence of numerous diseases. Understanding the physiological and pathological functions of gut bacteria and enabling early diagnosis of gut diseases heavily relies on accurate knowledge about their in vivo distribution. Consequently, there is a significant demand for noninvasive imaging techniques capable of providing real-time localization information regarding gut bacteria.

Magnetotactic Bacteria AMB-1 with Active Deep Tumor Penetrability for NIR-II Photothermal Tumor Therapy.

The complex tumor structure and microenvironment such as abnormal tumor vasculature, dense tumor matrix, and elevated interstitial fluid pressure greatly hinder the penetration and retention of therapeutic agents in solid tumors. The development of an advanced method for robust penetration and retention of therapeutic agents in tumors is of great significance for efficient tumor treatments. In this work, we demonstrated that magnetotactic bacteria AMB-1 with hypoxic metabolism characteristics can actively penetrate the tumor to selectively colonize deep hypoxic regions, which emerge as a promising intelligent drug carrier.

Ultrasound-Targeted Microbubble Destruction Enhances Inhibitory Effect of Apatinib on Angiogenesis in Triple Negative Breast Carcinoma Xenografts.

Ultrasound-targeted microbubble destruction (UTMD) has been proven as an effective technique to assist drugs to cross the vascular wall and cell membrane. This study was aimed at evaluating the synergistic antiangiogenic and growth-inhibiting effects of apatinib (APA) and UTMD on the triple negative breast cancer (TNBC). The TNBC xenograft model was established in nude mice ( = 40) which were then randomly divided into the APA plus UTMD (APA-U) group, UTMD group, APA group, and model control (M) group ( = 10 per group).

Can Nonfibrotic Nonalcoholic Steatohepatitis Be Effectively Identified by Supersonic Shear Imaging?

Supersonic shear imaging (SSI) is a relatively new technique to measure the elasticity of target tissues based on the shear wave propagation. The aim of this study was to evaluate the value of SSI in discriminating nonfibrotic nonalcoholic steatohepatitis (NASH) from the less severe nonalcoholic fatty liver disease (NAFLD), NASH with fibrosis, and the normal liver, as well as the relationship between various NAFLD pathologic or biochemical findings and SSI liver elasticity. Rabbits with NAFLD of different degrees were subjected to SSI for liver elasticity measurement.

Endovascular Repair of a Large Abdominal Aortic Aneurysm in a Patient Presenting with Lower Extremity Edema as a Result of Inferior Vena Cava Thrombosis.

Purpose: Abdominal aortic aneurysm (AAA) can present with symptoms because of aneurysmal compression of adjacent organ systems. This condition has always been treated by open surgical repair. Here, we report a case of an AAA complicated by inferior vena cava (IVC) thrombosis and deep venous thrombosis (DVT) due to IVC compression by aneurysm successfully treated by endovascular aneurysm repair (EVAR).
