Natural Sweetener Stevioside‐Based Dissolving Microneedles Solubilize Minoxidil for the Treatment of Androgenic Alopecia

Advanced Healthcare Materials, EarlyView.
This study addresses limitations of minoxidil (MXD) in treating androgenetic alopecia by using stevioside (STV) as a solubilizing agent and microneedle (MN) material. STV enhanced MXD's solubility and skin absorption, leading to improved drug delivery and significant hair regrowth in animal models, demonstrating strong potential for AGA treatment ...

Tailored Core‐Shell Nanocarrier for Therapeutic Drug Delivery via Visible Light Activation

Angewandte Chemie, EarlyView.
A core‐shell nanocarrier activated by visible light, composed of poly(3‐octylthiophene‐2,5‐diyl) (POT), iron oxide (II, III) (Fe3O4), polyvinyl alcohol (PVA), and trazodone tetraphenylborate (TRZ+ TPB−). During POT photooxidation (POT+), TRZ+ is liberated driven by the maintenance of particle's electroneutrality.

Salivary testosterone levels in preadolescent children

BMC Pediatrics, 2002
Background Saliva reflects the plasma free fraction of testosterone which is biologically active, and available for uptake by tissues. Testosterone concentration in saliva, though differing slightly from the concentration of unbound testosterone in serum,

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

Advanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Testosterone increases the virulence traits of uropathogenic Escherichia coli

Frontiers in Microbiology
Uropathogenic Escherichia coli (UPEC) is the most common cause of urinary tract infections (UTIs) in humans. Testosterone negatively impacts UTIs by affecting the immune response, leading to higher susceptibility of chronic cystitis in individuals with ...

p38 mediates T-2 toxin-induced Leydig cell testosterone synthesis disorder

Ecotoxicology and Environmental Safety, 2023
T-2 toxin is an unavoidable food and feed contaminant that seriously threatens human and animal health. Exposure to T-2 toxin can cause testosterone synthesis disorder in male animals, but the molecular mechanism is still not completely clear.

Bisphenol B Exposure Induces Miscarriage by Suppressing Migration/Invasion and Migrasome Formation

Advanced Science, EarlyView.
BPB (Bisphenol B) exposure up‐regulates ER (estrogen receptor) levels, enhances its interactions with the lnc‐HZ04 promoter region, and thus promotes ER‐mediated lnc‐HZ04 transcription. Subsequently, lnc‐HZ04 suppresses TCF4 (transcription factor 4)‐mediated PKCA (protein kinase C alpha) transcription and subsequently suppresses migration/invasion and ...

Disruption of Gut Microbiota‐Mediated De Novo NAD+ Synthesis Contributes to the Development of Polycystic Ovary Syndrome

Advanced Science, EarlyView.
This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

Hepatic KLF9 Deficiency Inhibits Dehydroepiandrosterone (DHEA)‐Induced Polycystic Ovary Syndrome via Liver‐Ovary Axis

Advanced Science, EarlyView.
The study shows that liver is a previously unrecognized extraovarian organ that plays a key role about androgen homeostasis in the development of DHEA‐induced PCOS. DHEA is the most common precursor of active androgen, such as DHT, and KLF9 is required for the conversion of DHEA to DHT and hepatic KLF9 might be a potential therapeutic target for PCOS ...
