Label‐Free Dual‐Modal Photoacoustic/Ultrasound Localization Imaging for Studying Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
This work develops a 3D label‐free photoacoustic/super‐resolution ultrasound imaging system as a comprehensive non‐invasive tool for acute kidney injury (AKI) study. This technique visualizes the intricate structure of renal microvessels and provides critical physiological insights, including renal hemodynamics and oxygenation.

Inhibiting the Histone Demethylase Kdm4a Restrains Cardiac Fibrosis After Myocardial Infarction by Promoting Autophagy in Premature Senescent Fibroblasts

open access: yesAdvanced Science, EarlyView.
Kdm4a downregulation restrains excessive cardiac interstitial fibrosis and remodeling by depressing the premature senescence of fibroblasts in the advanced stage after MI but does not affect early ventricular rupture. It verified that Kdm4a downregulation promotes autophagy in premature senescent fibroblasts by increasing the H3K9m3 modification of the

Neuronal C/EBPβ Shortens the Lifespan via Inactivating NAMPT

open access: yesAdvanced Science, EarlyView.
Schematic diagram illustrating the mechanism of shortened lifespan in Thy 1‐C/EBPβ transgenic mice and intervention strategies. Briefly, C/EBPβ/AEP escalation in the aging brain triggers NAMPT fragmentation and NAD+ depletion. Knockout of AEP from Thy 1‐C/EBPβ Tg/Tg mice ameliorates cognitive impairments and elongates the lifespan.

Semaphorin 3E–Plexin D1 Axis Drives Lung Fibrosis through ErbB2‐Mediated Fibroblast Activation

open access: yesAdvanced Science, EarlyView.
TGF‐β1 stimulation in fibroblasts leads to increased Furin expression, Furin‐mediated cleavage of P87‐Sema3E to P61‐Sema3E, which affects fibroblast function through the autocrine pathway, and the P61‐Sema3E‐PlexinD1 axis promotes fibroblast activation, proliferation and migration by affecting ErbB2 phosphorylation, which in turn activates the ErbB2 ...

Orexinergic neurons in the hypothalami of an Asiatic lion, an African lion, and a Southeast African cheetah

open access: yesJournal of Comparative Neurology, Volume 531, Issue 3, Page 366-389, February 2023., 2023
Photomicrograph of orexinergic neurons forming the main orexinergic neuronal cluster in the hypothalamus of a Southeast African cheetah. While showing the standard features of the orexinergic system, the Southeast African cheetah, along with an Asiatic and an African lion, also exhibits specializations in the organization of this system.

Euthanasia and assisted dying: what is the current position and what are the key arguments informing the debate?

open access: yesJournal of the Royal Society of Medicine, 2018
Summary Assisted dying is a highly controversial moral issue incorporating both physician-assisted dying (PAD) and voluntary active euthanasia. End-of-life practices are debated in many countries, with assisted dying receiving different consideration ...

Targeted DNA Nanomachine Enables Specific miRNA‐Responsive Singlet Oxygen Amplification for Precise Cutaneous Squamous Cancer Therapy

open access: yesAdvanced Science, EarlyView.
An intelligent DNA nanomachine based on DNA tetrahedron is proposed, incorporated with aptamer and specific miRNA‐responsive hairpin catalytic assembly (HCA), for precise therapy of cutaneous squamous cell carcinoma (cSCC) in mice, with barely systemic toxicity and inflammation.

High doses of zoledronic acid induce differential effects on femur and jawbone microstructure

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1487-1495, December 2022., 2022
Abstract Objectives The aim of this study is to investigate the long‐term effects on jaw and femur bone induced by oncologic doses of zoledronic acid in a young rat model. Material and Methods Six 12‐week‐old male Wistar rats received zoledronic acid (0.6 mg/kg) and six control rats received saline solution in the same volume.

Silicon Enhances Functional Mitochondrial Transfer to Improve Neurovascularization in Diabetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
These findings reveal that silicon exerts strong protective effects in diabetic bone defect models by selectively promoting Drp1‐Mff activity. Silicon facilitates precise regulation of mitochondrial dynamics to enable functional mitochondrial transfer.
