Hormesis was first defined by toxicologists who observed beneficial effects of very low doses of poisonous substances (‘poisons’).
‘Hormesis’ as defined by Southam and Ehrlich (1943) applies to
short- or long-lasting beneficial effects activated in cells after a
‘moderate’ stress (or harmful stimulus).
Hormesis is the idea that short, intermittent bursts of certain stressors can start a cascade of cellular processes that slow aging, improve overall health and make you more resilient, both physically and mentally. https://carolinatotalwellness.com/blog/index.php/2023/03/03/hormesis-the-beneficial-type-of-stress/
the concept of hormesis is about 130 years old, starting with the findings of Hugo Schulz [26,27] concerning the effects of nearly a dozen disinfectants on yeast metabolism. Schulz’s research was significant as it established the biphasic dose response within the framework of a modest overcompensation response to an initial disruption in homeostasis.
Schulz erroneously associated his biphasic dose response with the practice of homeopathy, asserting that he had discovered its explanatory principle [34]. This action of Schulz curtailed his career.

ホルミシスという言葉を最初に用いたのはソーサムとエーリッヒ（1943）だそう。
The term hormesis was first used in the peer-reviewed literature by Southam and Ehrlich [1] in 1943 to describe the effects of extracts of the red cedar tree on the growth of numerous fungal species that had the capacity to rot wood.

The bladder and urethra develop from the endoderm, the innermost of the three primary germ layers in an early embryo.The bladder develops from the upper end of the urogenital sinus, which is lined with endoderm and continuous with the allantois.

The ureters are derived from intermediate mesoderm during embryology.The intermediate mesoderm divides into the nephrogenic ridge, which forms the ureters, and the gonadal ridge, which forms the gonads.The urogenital ridge, a region of intermediate mesoderm, is the source of the embryonic kidney and the gonad, which gives rise to the urinary system.

The renal pelvis is derived from the ureteric bud, which is an outgrowth of the mesonephric duct, which originates from intermediate mesoderm.
