Finasteride can cause sexual problems and depression in young men.

Different sPLA2 enzymes affect immunity, skin and hair health, reproduction, and may be potential targets for therapy.

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

Amenorrhea, or the absence of periods, should be evaluated by age 15 or within five years of early breast development, and is most commonly caused by conditions like polycystic ovary syndrome and hypothalamic amenorrhea.

Mesenchymal stromal cells may help treat severe COVID-19, but more research is needed to confirm their effectiveness.

The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.

Estrogen increases blood vessel growth factor production, while testosterone blocks this increase.

The Notch signaling pathway helps in mouse hair development through a noncanonical mechanism that does not rely on RBPj or transcription.

COVID-19 and hypopituitarism (reduced pituitary gland function) are linked, with the latter's related health issues potentially worsening COVID-19 outcomes, and COVID-19 possibly increasing risk for pituitary complications.

Blocking 5α-reductase can harm memory and brain structure, and increase harmful brain changes in male mice used for Alzheimer's disease research.

Estazolam reduces anxiety-like behavior in PTSD by increasing allopregnanolone levels.

Drugs for hormone-related conditions might help treat mental disorders but could have serious side effects.

Bioengineered salivary glands in mice can produce saliva when tasting sour or bitter, but have different protein levels and nerve signals compared to natural glands.

LEF1 is essential for the development of airway glands and is regulated by the Wnt/ß-catenin pathway.

Exosomes from umbilical cord cells fix hearing loss and damaged ear hair cells in mice.

Healthcare claims databases can help monitor drug safety, but may report adverse events differently than direct surveillance.

The document concludes that stem cell inactivity is actively controlled and important for tissue repair and balance.

KLF4 is important for maintaining stem cells and has potential in cancer treatment and wound healing.

PNKP is essential for keeping adult mouse progenitor cells healthy and growing normally.

Different proteins are linked to the varying thickness of sheep and goat hair types.

Hairless mammals have genetic changes in both their protein-coding and regulatory sequences related to hair.

Hormones control reproduction and are crucial for body balance.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

Humans have limited regenerative abilities, but new evidence shows the adult brain and heart can regenerate, and future treatments may improve this by mimicking stem cell environments.

Traditional Chinese medicinal foods may help manage long-term post-COVID symptoms.

Neuroactive steroids may affect the risk and treatment of alcohol use disorders.

The conference presented findings on how vitamin D levels, genetic factors, and lifestyle choices like smoking and yoga affect various health conditions and diseases.

Nanostructured lipid carriers are effective for treating hyperpigmentation in women aged 30-40.
