December 2017 in “bioRxiv (Cold Spring Harbor Laboratory)” This study found that Endoglin is crucial for proper hair follicle cycling and the activation of hair follicle stem cell niches, based on its role in the feedback crosstalk between Wnt/β-catenin and Bmp/Smad signals.
September 2017 in “The journal of investigative dermatology/Journal of investigative dermatology” This study suggests that the outer root sheath of human hair follicles may act as a "metabolic center," capable of synthesizing glucose from lactate, which supports glycogen metabolism.
June 2017 in “DOAJ (DOAJ: Directory of Open Access Journals)” This study found that finasteride's solubility and bioavailability were improved when using a dimethyl-β-cyclodextrin inclusion complex compared to the drug alone.
April 2017 in “Journal of Investigative Dermatology” This study identified the dermal sheath as a key component of the hair follicle niche, essential for outer root sheath regression during the hair cycle, highlighting its importance in hair follicle support and regulation.
This study found that 6-Gingerol significantly suppressed hair growth in mice by interfering with the hair cycle and altering growth factor concentrations.
April 2016 in “Plastic and reconstructive surgery. Global open” This article lists online educational resources from the American Society of Plastic Surgeons but reports no new research findings.
March 2016 in “Institutional Repositories DataBase (IRDB)” This study discusses the effects of collagen hydrolysates and the dipeptide Pro-Hyp on gene expression related to hair and epidermis development in mouse skin and reports no new clinical results.
January 2015 in “OhioLink ETD Center (Ohio Library and Information Network)” This animal study found that high dietary vitamin A levels altered hair cycling by affecting WNT and BMP signaling pathways in mice, which could be reversed by reducing vitamin A intake.
This study found that in both rodents and humans, knee laxity increased at certain phases of the reproductive cycle due to sex-steroid influence, particularly under high levels of estrogen and progesterone.
November 2013 in “Institutional Repositories DataBase (IRDB)” In this study, γ-ray exposure in mice decreased hair follicle density and pigmentation, suggesting damage to stem cells affecting hair follicle regeneration.
August 2012 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This study found that FGF18 is crucial for regulating hair follicle rest and growth phases, as its absence in mice leads to a shorter resting phase and rapid hair cycling.
July 2012 in “EFSA supporting publications” This technical report from the European Food Safety Authority responds to comments on its previous scientific opinion regarding a health claim about spermidine and hair growth, reporting no new experimental results.
January 2012 in “Else Kröner-Fresenius Symposia” This symposium reported that DNA damage accumulation in aging stem cells affects genome integrity, highlighting novel mechanisms like Bmi1's role in DNA repair and the involvement of BATF in lymphoid differentiation.
October 2011 in “InTech eBooks” This article reviews idiopathic hypogonadotropic hypogonadism (IHH), discussing its genetic and pathophysiological features, and it does not present new clinical results.
August 2011 in “Planta Medica” This study suggests that the hair growth-promoting effects of 4-O-methylhonokiol may be linked to its ability to modulate TGF-β-induced cell cycle arrest and oxidative stress in HaCaT cells.
December 2010 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This entry does not provide an abstract or new research findings, so no specific results are available for summary.
October 2010 in “International journal of radiation oncology, biology, physics” In this randomized study, patients with early favorable Hodgkin lymphoma showed similar complete remission and survival rates whether receiving 2 or 4 cycles of ABVD and 20 Gy or 30 Gy IFRT, though reduced toxicity was associated with fewer cycles and lower radiation doses.
January 2010 in “Bradford Scholars (University of Bradford)” This study found that microRNAs play key roles in regulating gene expression during the hair cycle in mice, impacting follicle growth and skin homeostasis through mechanisms involving major signalling pathways.
This article discusses the roles of retinoic acid in cellular differentiation and its side effects like hair loss, but reports no new clinical findings.
May 2009 in “Hair transplant forum international” This review discusses Dr. Gill Westgate's background in hair growth regulation and industry experience, but reports no new findings or results.
January 2002 in “Europe PMC (PubMed Central)” This study presents a follicular automaton model that simulates human hair cycle dynamics and can reproduce hair patterns similar to diffuse or androgenetic alopecia by incorporating spatially heterogeneous parameters and follicle miniaturization.
January 2001 in “Nishi Nihon hifuka” This review discusses differences in hair cycles and epidermal turnover using electronic evaluation, but it reports no new clinical results.
