research Red Ginseng (Panax Ginseng Meyer) Oil: A Comprehensive Review of Extraction Technologies, Chemical Composition, Health Benefits, Molecular Mechanisms, and Safety
Red ginseng oil is believed to have various health benefits and is safe, but more research is needed to fully understand how it works.
research Sexual Hormones in Human Skin
Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.
research Recent Progress in the Effect of Ferroptosis of Hepatic Stellate Cells on the Development of Liver Fibrosis
Inducing ferroptosis in hepatic stellate cells is crucial for treating liver fibrosis.
research Targeted Expression of Spermidine/Spermine N1-Acetyltransferase Increases Susceptibility to Chemically Induced Skin Carcinogenesis
The study used transgenic mice with targeted expression of spermidine/spermine N1-acetyltransferase (SSAT) in hair follicle keratinocytes to investigate susceptibility to skin cancer. These K6-SSAT transgenic mice, bred onto a tumor-resistant C57BL/6 background, showed a 10-fold increase in epidermal tumors when exposed to a carcinogenesis protocol involving 7,12-dimethylbenz[a]anthracene and 12-O-tetradecanoylphorbol-13-acetate. The transgenic mice exhibited elevated SSAT activity and protein levels, along with increased putrescine and N1-acetylspermidine, indicating enhanced polyamine catabolism. The study concluded that this activation of polyamine catabolism might play a crucial role in chemically induced skin cancer, as evidenced by the early onset and progression to carcinomas in the transgenic mice.
research News in Brief
Researchers found potential new targets for treating melanoma and nonmelanoma skin cancers, and identified a possible cause and treatment for male pattern baldness and eczema.
research The Stem Cell Niche in Regenerative Medicine
Targeting and modifying the stem cell niche can improve regenerative therapies.
research The Pathobiology of Skin Aging
The document reviewed the pathobiology of skin aging, identifying it as a degenerative process influenced by intrinsic and environmental factors, leading to structural changes such as epidermal thinning, loss of dermal papillae, and decreased collagen and elastin, which contribute to wrinkles and sagging. It highlighted the role of stem cell dysfunction, genetic factors, and immune system decline in skin deterioration, noting increased susceptibility to infections and skin cancer. The review argued for recognizing skin aging as a disease due to its health implications and variability among individuals. It also discussed the psychological impact of skin aging and advocated for public health strategies to mitigate its progression. The document emphasized the complex interplay between skin aging, stem cell function, and immune response, suggesting potential interventions like targeting sirtuins to reverse aging effects.
research 5 Alpha-Reductase Inhibitors: What's New?
A new drug, dutasteride, is at least as effective as the older drug, finasteride, for treating enlarged prostate and may have additional uses.
research From Structural Resilience to Cell Specification: Intermediate Filaments as Regulators of Cell Fate
Intermediate filaments are crucial for cell differentiation and stem cell function.
research Human Regulatory T Cells: Role in Autoimmune Skin Diseases and Post-Transplant Nonmelanoma Skin Cancers
Understanding how Regulatory T Cells work could help create treatments for certain skin diseases and cancers.
research The Challenging Consultation: Management of Melanoma
The conclusion is that managing hair loss conditions like FFA and melanoma requires individualized approaches, considering new findings and balancing treatment benefits with potential risks.
research Replicative Stress, Stem Cells, and Aging
Maintaining DNA health in stem cells is key to preventing aging and tissue breakdown.
research Intractable Diffuse Alopecia Caused by Multifactorial Side-Effects in Treatment of Acute Lymphocytic Leukemia: Connection to Iatrogenic Failure of Estrogen Secretion
The patient's long-term hair loss was caused by leukemia treatments and low estrogen levels, worsened by her genetic tendency for hair loss.
research Phosphatidylinositol 3-Kinase/Akt-Dependent and Independent Protection Against Apoptosis in Normal Human Melanocytes
Normal human melanocytes can avoid cell death through multiple pathways.
research Occult Ovarian Leydig Cell Tumor: When Laboratory Tells More Than Imaging
Blood tests can detect ovarian Leydig cell tumors when scans don't, and surgery can confirm and treat these tumors.
research P21Waf1/Cip1 Is Differentially Expressed in Epidermal Versus Follicular Melanocytes and Melanoma Cells and Is Phenotypically Regulated by UVB-Mediated Apoptosis
The protein p21 is more abundant in normal skin cells than in melanoma cells and may help protect against melanoma, with UVB light affecting its levels.
research Is COVID-19 a Risk Factor for Progression of Benign Prostatic Hyperplasia and Exacerbation of Its Related Symptoms?: A Systematic Review
COVID-19 might worsen symptoms and progression of benign prostatic hyperplasia, possibly due to inflammation and metabolic disturbances in the prostate gland. More research is needed to confirm this.
research Comparative Transcriptome Profiling Provides New Insights Into Mechanisms of Androgenetic Alopecia Progression
