Infliximab improved skin and bowel symptoms in Crohn's disease but caused side effects and the disease returned after stopping treatment.

General surgeons are crucial for handling various emergencies in small hospitals and should balance broad skills with some specialization for effective, economical community care.

A chubby child can still be malnourished.

Herbal remedies can cause adverse effects and need more safety research.

Epithelial stem cells are crucial for tissue renewal and repair, and understanding them could improve treatments for damage and cancer.

Keratins help protect cells, aid in cancer diagnosis, and influence cancer behavior and treatment.

Targeting colon cancer stem cells might lead to better treatment results.

Stem cells help heal wounds by rapidly dividing and migrating to the wound edge.

Hair and nail cells share similar proteins, indicating a common differentiation pathway.

The document concludes that the understanding of scar formation is incomplete and current prevention and treatment for hypertrophic scars and keloids are not fully effective.

Certain proteins, Lgr5 and Lgr6, are important markers of adult stem cells and are involved in tissue repair and cancer development.

Wnt signaling is crucial for pigmented hair regeneration by controlling stem cell activation and differentiation.

TGF-β is crucial for tissue repair and can cause diseases if not properly regulated.

Hoxc13 gene is essential for hair, nail, and papilla development.

Tofacitinib is safe and effective for severe alopecia areata, but hair loss may return 2 months after stopping treatment.

The document concludes that the 5 alpha-reductase enzymes are important in steroid metabolism and related to various human diseases, with inhibitors used to treat conditions like male pattern baldness and prostate issues.

Stem cells help heal skin wounds by moving and changing roles, working with other cells, and needing more research on their activation and behavior.

Epirubicin is as effective as doxorubicin for cancer treatment with less heart damage, but doesn't work on doxorubicin-resistant cancers.

Zinc is crucial for growth and health in rats.

Keratin expression reflects cell organization and differentiation, not causes it.

Lichen planus is a skin condition that can resolve on its own, is linked to hepatitis C, and increases the risk of skin cancer.

New research suggests that skin cell renewal may not require a special type of cell previously thought to be essential.

Cancer cells often have more copies of TERT and TERC genes, which helps them grow and could affect patient outcomes.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

Protoporphyrin IX is useful in cancer treatment but can cause health problems if not properly regulated.

Different types of stem cells and their environments are key to skin repair and maintenance.

Fat-derived stem cells show promise for skin repair and reducing aging signs but need more research for consistent results.

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.

Cepharanthine is a well-tolerated drug with multiple medical uses, including anti-inflammatory and anti-cancer properties.

Asia has made significant progress in tissue engineering and regenerative medicine, but wider clinical use requires more development.
