Transcutol P best increases Finasteride absorption for hair loss treatment.
research Motoneuron-Specific PTEN Deletion in Mice Induces Neuronal Hypertrophy and Regeneration After Facial Nerve Injury
Deleting the PTEN gene in mice causes nerve cells to grow larger and heal better after injury, but may cause overgrowth and hair loss in older mice.
research Determination of Estradiol and Progesterone Concentrations in Human Scalp Hair
Hair levels of estradiol and progesterone are higher in premenopausal than postmenopausal women, but the difference isn't statistically significant, indicating the need for a better measurement method.
research Effect of Carbamates on mRNA Encoding Lipid Enzymes in Hamster Flank Organs
Carbamates may help treat androgen-dependent conditions by changing how certain lipid enzymes are produced.
research Boron Deficiency Responses in Maize (Zea Mays L.) Roots
Boron deficiency in maize affects leaf boron levels and nutrient uptake differently depending on root hair presence and soil type.
research Sexually Dimorphic Effect of Progesterone and Its Reduced Metabolites on the Gene Expression of Myelin Proteins in Rat Schwann Cells
Progesterone and its metabolites affect myelin protein expression differently in male and female rat Schwann cells.
research Hair Growth Inhibition by Psychoemotional Stress: A Mouse Model for Neural Mechanisms in Hair Growth Control
Stress can stop hair growth in mice, and treatments can reverse this effect.
research Neuronal Plasticity of the Brain-Skin Connection: Stress-Triggered Up-Regulation of Neuropeptides in Dorsal Root Ganglia and Skin via Nerve Growth Factor-Dependent Pathways
Stress increases certain chemicals in the skin and nerves, which might worsen skin conditions.
research Investigation of Drug Partition Property in Artificial Sebum
The conclusion is that measuring how drugs partition into artificial sebum is important for predicting their delivery into hair and sebaceous follicles, and it provides better information than traditional methods.
