Homeostasis as the Mechanism of Evolution. [PDF]
Homeostasis is conventionally thought of merely as a synchronic (same time) servo-mechanism that maintains the status quo for organismal physiology. However, when seen from the perspective of developmental physiology, homeostasis is a robust, dynamic ...

Hypoxia in the Initiation and Progression of Neuroblastoma Tumours [PDF]
Neuroblastoma is the most frequent extracranial solid tumour in children, causing 10% of all paediatric oncology deaths. It arises in the embryonic neural crest due to an uncontrolled behaviour of sympathetic nervous system progenitors, giving rise to ...

Ultrasound in Women's Health: Mechanisms, Applications, and Emerging Opportunities
As healthcare moves toward decentralization, ultrasound technologies are evolving from strictly imaging tools in clinical settings into versatile diagnostic and therapeutic platforms, with growing roles addressing women's health needs. This review highlights how ultrasound's underlying physical mechanisms can be harnessed to reduce disparities in women'

Aldosterone‐producing adenomas (APAs) develop via two distinct paths: directly from adrenal zona glomerulosa (zG) cells, or stepwise from zG cells through aldosterone‐producing micronodules (APMs) before progressing to APAs. Advanced single‐cell and spatial analyses identified distinct cell states linked to oxidative stress and cell–cell interactions ...

Depression, a prevalent neuropsychiatric disorder with unclear pathogenesis, involves dysfunctional adenylyl cyclase 8 (Adcy8) as a key risk factor. Chronic stress selectively reduces Adcy8 expression in the dorsal CA1 (dCA1) neurons. Depletion of Adcy8 in dCA1 excitatory neurons induces depressive‐like behaviors by impairing neuronal excitability and ...

Heterotopic adrenal gland in undescendent testis – Case report
Heterotopic adrenal cortex is usually found in the kidney, retroperitoneum and spermatic cord. The adrenal gland has a dual embryonic origin: the cortex arises from the mesoderm and the medulla from ectoderm of the neural crest. Adrenal cortex and gonads
