Clear cell hidradenoma is a tumor that originates from a sweat gland and typically involves the dermis and subcutaneous tissue. Malignant clear cell hidradenoma is very rare, and surgical excision is usually performed without imaging. There are few reports of the ultrasonographic findings of malignant clear cell hidradenomas. Herein, we present the ultrasonographic characteristics of a malignant clear cell hidradenoma.

Background: Duchenne muscular dystrophy (DMD) is a prevalent, fatal degenerative muscle disease with no effective treatments. Mdx mouse model of DMD exhibits impaired muscle performance, oxidative stress, and dysfunctional autophagy. Although antioxidant treatments may improve the mdx phenotype, the precise molecular mechanisms remain unclear.

[Biological essence of blood stasis-heat syndrome in ischemic stroke and current research status of traditional Chinese medicine prevention and treatment based on thromboinflammation reaction].

Zhongguo Zhong Yao Za Zhi

December 2024

Institute of Basic Theory on Integrated Traditional Chinese and Western Medicine, College of Integrated Traditional Chinese Medicine and Western Medicine, Hunan University of Chinese Medicine Changsha 410208, China.

Blood stasis-heat syndrome is one of the common syndromes of ischemic stroke, which is manifested as syndromes of blood stasis and heat during the pathological progression of patients with ischemic stroke, but there is a lack of systematic research on its biological essence. Thromboinflammation reaction is a newly proposed pathological mechanism highly associated with thrombosis and inflammatory reaction, and it refers to the fact that under the mediation of von Willebrand factor(vWF) and the kallikrein-kinin system, thrombosis and inflammatory reaction interact with each other. Activation of T cells and neutrophils further aggravates thrombosis and worsens the pathological progression of ischemic stroke.

Design, evaluation, and in vitro-in vivo correlation of self-nanoemulsifying drug delivery systems to improve the oral absorption of exenatide.

J Control Release

January 2025

Department of Pharmacy, University of Copenhagen, Universitetsparken 2, Copenhagen 2100, Denmark; Bioneer A/S, Kogle Allé 2, Hørsholm 2970, Denmark. Electronic address:

The ability to predict the absorption of exenatide (Ex), a GLP-1 analogue, after oral dosing to rats in self-nanoemulsifying drug delivery systems (SNEDDS), using in vitro methods, was assessed. Ex was complexed with soybean phosphatidylcholine (SPC) prior to loading into SNEDDS. A design of experiments (DoE) approach was employed to develop SNEDDS incorporating medium-chain triglycerides (MCT), medium-chain mono- and diglycerides (MGDG), Kolliphor® RH40, and monoacyl phosphatidylcholine.
