Menopause causes significant changes in the vaginal introitus, but less so in the labia majora, which may lead to symptoms of vaginal atrophy.

New insights into cell communication in psoriasis suggest innovative drug treatments.

Some growth factors, while important for normal body functions, can cause diseases when not regulated properly.

Sex neurosteroids cause different effects on hippocampal synaptic plasticity in males and females.

The research identifies genes linked to wool quality in sheep and provides insights to improve wool production.

The conclusion is that cerebrovascular diseases can cause seizure-like activity in stroke patients, which can be improved with antiepileptic drugs.

Hair follicles in mutant mice self-organize into ordered patterns within a week.

CPK1 helps root hair growth in Arabidopsis by activating channels for calcium signaling.

DrugNet effectively identifies new uses for existing drugs and may save resources in drug development.

Researchers created LabeledIn, a detailed list of drug uses, showing the importance of human input in making such lists.

New single-cell analysis techniques are improving our understanding of stem cells and could help in treating diseases.

Oxidative stress may contribute to hair loss in alopecia areata and antioxidants could potentially help as a treatment.

Three new types of a skin blistering disease were found, caused by specific gene mutations.

Fine wool sheep have more genes for wool quality, while coarse wool sheep have more for skin and muscle traits.

Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.

Certain long non-coding RNAs in cashmere goats affect hair growth when treated with a specific growth factor.

The hair keratin gene KRT81 is found in both normal and breast cancer cells and helps them invade surrounding tissues.

Scientists created stem cells that can grow hair and skin.

The document concludes that understanding hair and feather regeneration can help develop new regenerative medicine strategies.

About 20% of red foxes and jackals in western Iran have at least one type of ectoparasite, with fleas being the most common.

About 19% of foxes and 18% of jackals in southwest Iran have at least one type of ectoparasite, mainly fleas.

The conclusion is that a combination of noninvasive treatments and lifestyle changes can improve skin health during menopause.

Editing the FGF5 gene in sheep increases fine wool growth.

A device was made in 2008 to measure hair loss severity. Other findings include: frizzy mutation in mice isn't related to Fgfr2, C/EBPx marks preadipocytes, Cyclosporin A speeds up hair growth in mice, blocking plasmin and metalloproteinases hinders healing, hyperbaric oxygen helps ischemic wound healing, amniotic membranes heal wounds better than polyurethane foam, rhVEGF165 from a fibrin matrix improves tissue flap viability and induces VEGF-R2 expression, and bFGF enhances wound healing and reduces scarring in rabbits.

Hair follicles in the back of the rosette fancy mouse have reversed orientations due to a gene mutation.

A gene network led by RSL4 is crucial for early root hair growth in response to cold in Arabidopsis thaliana.

Using anabolic-androgenic steroids can harm men's reproductive health and increase the risk of heart problems and death.

Large-scale reconstructions enhance understanding of vibrissal sensory mapping in the brain.

The conclusion is that certain genetic factors and blood types may affect COVID-19 severity, but changes in ACE2 and TMPRSS2 genes are not clearly linked to it.

Using low-dose IL-2 to increase regulatory T cells might be a safe way to treat type 1 diabetes without severe side effects.
