Targeted delivery of Saikosaponin A and doxorubicin via hyaluronic acid-modified ZIF-8 nanoparticles for TNBC treatment: Inhibiting metastasis and reducing cardiotoxicity.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by the absence of estrogen receptors, progesterone receptors, and HER2 expression, making traditional hormone and targeted therapies ineffective. Chemotherapy remains the primary treatment for TNBC; however, it has failed to adequately address the high rates of recurrence and metastasis, underscoring the urgent need for new therapeutic strategies. This study investigates Saikosaponin A (SSA), a compound extracted from traditional Chinese medicine, for its potential to enhance the efficacy of doxorubicin (DOX) chemotherapy while reducing TNBC metastasis and mitigating DOX-induced cardiotoxicity.

Two new species of (Agaricales, Strophariaceae) from the southwest of China.

Two new mushroom species from Southwest China, and , are described in this study. is characterized by its dry pileus with slightly recurved and triangular scales, cylindrical basidiospores, and two types of pleurocystidia-leptocystidia and chrysocystidia-as well as its growth on soil. is identified by a brownish-orange pileus with numerous brown fibrillose scales; pale brown lamellae with even edges; a stipe covered with recurved fibrillose scales; elliptical spores with a distinct but small germ pore; and pleurocystidia containing typical amorphous refractive inclusions of chrysocystidia.

Green synthesis of carbon dots from fish scales for selective turn off-on detection of glutathione.

Carbon dots as fluorescent probes were fabricated using readily available grass carp fish scales as the carbon source one-step synthesis based on a pyrolytic reaction. The as-prepared grass carp fish scale carbon dots (GF-CDs) exhibited good biocompatibility and excellent optical properties with a high fluorescence quantum yield of 23.8%.

Serendipitous Ureteral Stone Revealed on 99mTc-MDP Bone Scintigraphy.

A 62-year-old man with esophageal cancer was referred for a Tc-MDP bone scintigraphy for staging. No metastatic lesion in the bone was identified. However, the images showed focally increased activity in the left pelvis, which were confirmed as ureteral stone on the SPECT/CT images.
