Tang Z, Zhang X, Cheng C, Xu Y, Deng G, Zhou X, Liu S. Correlation between mental status and prevalence of asthenopia in Chinese college students. Graefes Arch Clin Exp Ophthalmol 2024:10.1007/s00417-024-06551-5. [PMID: 38916723 DOI: 10.1007/s00417-024-06551-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 06/02/2024] [Accepted: 06/07/2024] [Indexed: 06/26/2024] Open
Abstract
BACKGROUND The purpose of this study was to identify the possible association between mental status and the risk of self-reported asthenopia among college students in China. METHODS Ten thousand students were randomly assessed in the study using a self-reported asthenopia questionnaire. Their demographic characteristics and mental status were recorded. Univariate analysis was performed to preliminarily select potential risk and protective factors. Then, multivariate logistic regression was used to estimate odds ratios for the selected risk factors of interest. RESULTS Among the 8370 students who completed the survey, the prevalence of asthenopia was 61.0%. Multivariate analysis revealed a significant relationship between asthenopia and depressive symptoms (OR 1.511 95% CI: 1.350-1.691), obsessive-compulsive symptoms (OR 1.477, 95% CI: 1.338-1.632), gender and study load. The place college students spent their off-hours (OR 0.841, 95% CI: 0.784-0.902) was found to be the strongest factor for decreasing the occurrence of asthenopia complaints. CONCLUSION Asthenopia appears common in Chinese college students. In addition to depressive symptoms, we should pay attention to obsessive-compulsive symptoms when considering means of preventing asthenopia. Harmonious social relationships, outdoor off-hour activities and exercising more than three times per week are crucial to relieving visual fatigue. Further study is still needed in this area.

[PMID: 38892763 PMCID: PMC11172682 DOI: 10.3390/jcm13113052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2024] [Revised: 05/13/2024] [Accepted: 05/17/2024] [Indexed: 06/21/2024] Open
Abstract
The most common type of alopecia in women is female androgenetic alopecia (FAGA), characterized by progressive hair loss in a patterned distribution. Many oral therapies, including spironolactone (an aldosterone antagonist), androgen receptor blockers (e.g., flutamide/bicalutamide), 5-alpha-reductase inhibitors (e.g., finasteride/dutasteride), and oral contraceptives, target the mechanism of androgen conversion and binding to its respective receptor and therefore could be administered for the treatment of FAGA. Despite significant advances in the oral treatment of FAGA, its management in patients with a history of gynecological malignancies, the most common cancers in women worldwide, may still be a concern. In this review, we focus on the safety of antiandrogens for the treatment of FAGA patients. For this purpose, a targeted literature review was conducted on PubMed, utilizing the relevant search terms. To sum up, spironolactone seems to be safe for the systemic treatment of FAGA, even in high-risk populations. However, a general uncertainty remains regarding the safety of other medications in patients with a history of gynecologic malignancies, and further studies are needed to evaluate their long-term safety in patients with FAGA and risk factors to establish an optimal risk assessment and treatment selection protocol.

Abstract
BACKGROUND Androgenetic alopecia (AGA), also referred to as male or female pattern hair loss, is the commonest cause of chronic hair loss and affects up to 80% of men by the age of 70. Despite a high prevalence, there are few approved therapies, which show minimal efficacy. OBJECTIVES This systematic review aims to evaluate the efficacy of platelet-rich plasma (PrP) in the treatment of AGA in male patients. METHODS MEDLINE, EMBASE, Cochrane (CENTRAL), CINAHL, clinicaltrials.gov, Google Scholar and the Science Citation Index database were searched to identify eligible studies. All randomized controlled trials (RCTs) and prospective cohort studies related to PrP use in AGA were included. Primary outcomes included changes in hair density and hair count. Methodological quality was assessed using bias assessment tools. RESULTS Eight RCTs and one cohort study were included in the review with a total of 291 participants. Six studies reported a statistically significant increase in hair density in the PrP group versus the control. Five studies reported a statistically significant increase in hair count with PrP. Seven studies showed moderate risk and two showed low risk of bias. CONCLUSION In a methodologically robust review on the effectiveness of PrP on male AGA, PrP demonstrated some potential to be used therapeutically. However, the low quality of evidence, moderate risk of bias, and high heterogeneity of included studies limit inferences and call for more robust designs to investigate this further.

Abstract
Hair follicles, which are connected to sebaceous glands in the skin, undergo cyclic periods of regeneration, degeneration, and rest throughout adult life in mammals. The crucial function of hair follicle stem cells is to maintain these hair growth cycles. Another vital aspect is the activity of melanocyte stem cells, which differentiate into melanin-producing melanocytes, contributing to skin and hair pigmentation. Sebaceous gland stem cells also have a pivotal role in maintaining the skin barrier by regenerating mature sebocytes. These stem cells are maintained in a specialized microenvironment or niche and are regulated by internal and external signals, determining their dynamic behaviors in homeostasis and hair follicle regeneration. The activity of these stem cells is tightly controlled by various factors secreted by the niche components around the hair follicles, as well as immune-mediated damage signals, aging, metabolic status, and stress. In this study, we review these diverse stem cell regulatory and related molecular mechanisms of hair regeneration and disease conditions. Molecular insights would provide new perspectives on the disease mechanisms as well as hair and skin disorder treatment.

Abstract
OBJECTIVES To investigate the effectiveness and safety of combination of 655 nm low level laser helmet device with topical 2 % minoxidil solution at FPHL in Chinese population. MATERIALS AND METHODS Randomized, parallel, controlled, single-blind clinical trial was conducted. FPHL subjects were randomly allocated into 2 % minoxidil group and combination group. The 2 % minoxidil group received 1 ml topical 2 % minoxidil solution twice daily for 24 weeks. The combination group received 1 ml topical 2 % minoxidil solution twice daily together with 20 min 655 nm low-level laser helmet once every other day for 24 weeks. Hair parameters in two scalp areas including midscalp and vertex were evaluated at baseline, 12th week and 24th week. RESULTS In midscalp area, the combination group showed a lower increase in intermediate hair percentage than 2 % minoxidil group, which was statistically significant. Besides, the combination group had statistically significant increase than 2 % minoxidil group in mean hair diameter. Reported relative adverse events included slightly hair loss (27.8 %), desquamation (19.0 %), pruritus (15.2 %), seborrhea (2.5 %) and hypertrichosis (2.5 %). CONCLUSION In our trial, LLLT was demonstrated as a useful supplementary treatment for FPHL and the combination with 2 % minoxidil accomplished better improvement in intermediate hair enlargement and hair diameter of midscalp for FPHL.

Abstract
Objective: Umbilical cord-derived mesenchymal stem cell membrane-loaded minoxidil (MXD) nanoparticles (STCM-MXD-NPs) were prepared to investigate their effects on hair growth in C57BL/6J mice. Methods: STCM-MXD-NPs were obtained by freeze-thawing and differential centrifugation, and their effects on hair growth were evaluated using C57BL/6J mice. The mRNA and protein expression levels of vascular endothelial growth factor (VEGF) and insulin-like growth factor-1 (IGF-1) were detected by real-time polymerase chain reaction and enzyme-linked immunosorbent assays, respectively. Protein expression levels of marker of proliferation Ki-67 (MKI67) and β-catenin (CTNNB) in skin tissue were detected by immunohistochemistry. Results: STCM-MXD-NPs improved MXD solubility. They released the drug slowly, increasing its transdermal properties, accumulation in the skin, and content in the hair bulb tissues with a better efficacy than that of ordinary MXD. Moreover, STCM-MXD-NPs significantly upregulated the mRNA and protein levels of VEGF and IGF-1 and promoted the protein expression of MKI67 and CTNNB in mouse skin tissues, promoting mouse hair growth. Conclusion: Stem cell membrane-loaded MXD nanoparticles with slow-release properties increased MXD accumulation in the skin by improving its transdermal properties, increasing VEGF, IGF-1, MKI67, and CTNNB expression levels and promoting hair growth in C57BL/6J mice.

Abstract
Androgenetic alopecia (AGA) is the most prevalent type of hair loss in women and men. Recently, a European consensus group published guidelines for the diagnostic evaluation of AGA in men, women, and adolescents. This S1 guideline presents expert opinion-based recommendations for gender-dependent steps in the diagnostic procedure, which can easily be implemented in the daily clinical routine. For diagnosing AGA, detailed anamnesis and objective learning are not enough because there are several conditions mimicking this disease. Trichoscopy can be considered an important, non-invasive tool for diagnosing hair and scalp disorders that may have similar clinical signs to AGA.

Abstract
Background The most prevalent cause of hair loss is androgenetic alopecia. Improved therapeutic modalities may result from knowing how stress affects hair growth, incorporating stress-coping methods into the treatment of hair loss disorders, and developing new pharmacotherapeutic approaches. This study aimed to examine the psychosocial burden of androgenetic alopecia in Saudi Arabia. Materials and Methods A cross-sectional online survey study was conducted among patients with androgenetic alopecia in Saudi Arabia in February 2023. A previously developed questionnaire was adapted from a previously published tool and used in this study. This association between patients' characteristics and the level of psychosocial disease was identified using binary logistic regression analysis. Results This study included 1230 patients. The majority of the patients (78.0%) reported that they felt embarrassed by their androgenetic alopecia. The median score of the psychosocial impact of androgenetic alopecia on the patients was 1.00 (0.00-2.00), which is equal to 10.0%, reflecting a low level of psychosocial burden on the patients by their condition. Binary logistic regression analysis identified that patients without a family history of androgenetic alopecia were 36.0% less likely to be affected psychosocially by their condition (P < 0.01). Conclusions A low-level psychosocial effect was seen in our study among individuals with androgenetic alopecia. Further research should be done to determine how the type of alopecia affects patients' psychological results, as well as the influence of the disease's duration on those outcomes. Dermatologists are recommended to raise patients' knowledge of their disease and lessen stigmatization in the meantime.

Abstract
Male-pattern hair loss (MPHL) is common and highly heritable. While genome-wide association studies (GWAS) have generated insights into the contribution of common variants to MPHL etiology, the relevance of rare variants remains unclear. To determine the contribution of rare variants to MPHL etiology, we perform gene-based and single-variant analyses in exome-sequencing data from 72,469 male UK Biobank participants. While our population-level risk prediction suggests that rare variants make only a minor contribution to general MPHL risk, our rare variant collapsing tests identified a total of five significant gene associations. These findings provide additional evidence for previously implicated genes (EDA2R, WNT10A) and highlight novel risk genes at and beyond GWAS loci (HEPH, CEPT1, EIF3F). Furthermore, MPHL-associated genes are enriched for genes considered causal for monogenic trichoses. Together, our findings broaden the MPHL-associated allelic spectrum and provide insights into MPHL pathobiology and a shared basis with monogenic hair loss disorders.

Abstract
Platelet-rich plasma (PRP) contains a variety of growth factors and has been widely used in maxillofacial surgery, orthopedics, plastic surgery, ophthalmology, and other fields. In recent years, with the increasing morbidity of androgenetic alopecia (AGA), the use of PRP has also increased. The objective of this article was to evaluate the efficacy and safety of PRP for AGA. We searched PubMed, Embase, Web of Science, and Cochrane Library, covering the databases from their earliest records until March 2022. We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) to explore the effects of PRP for hair density, hair count, and hair diameter in AGA. Nine trials involving 238 patients were included. The meta-analysis showed that PRP for AGA increased hair density at 3 and 6 months with statistically significant differences compared with the placebo (P < .05). PRP also increased hair count and hair diameter compared with the baseline, but there was no significant difference compared with the placebo (P > .05). Two of the 7 studies reported adverse reactions. No serious adverse reactions were found. In conclusion, PRP is an effective and safe treatment for increasing the hair density in AGA. Trial registration: The systematic review was registered with PROSPERO (CRD42022362432).

Abstract
INTRODUCTION Treatments for AGA have yet to produce satisfactory outcomes and may cause intolerable side effects. Recent studies have reported that adipose tissue-derived stem cell conditioned media (ADSC-CM) could induce hair growth and regeneration. OBJECTIVE To investigate the efficacy of ADSC-CM combined with minoxidil for hair regeneration therapy in male AGA. METHODS This study lasted for 6 weeks. Subjects were divided into two groups: concentrated and non-concentrated ADSC-CM. Scalp was divided vertically in half before intradermal injection was administered from the frontal region of the scalp toward the vertex with a 30G needle, spaced about 1 cm apart. Treatment side received 2 ml of ADSC-CM; the other side was given 2 ml of NaCl 0.9% as placebo. Patients applied 5% minoxidil twice daily post-injection. Improvements were assessed using photographs and trichoscan every 2 weeks. RESULTS Hair count, hair density, and mean thickness increased significantly on both sides after 6 weeks, while vellus rate decreased proportionally with the increase of terminal rate. No statistically significant differences between treatment groups were found. Minimum side effects were reported, and subjects were satisfied with the results. CONCLUSION Combination of ADSC-CM and minoxidil could be a potential agent for hair regrowth. Follow-up research with extensive populations, longer duration, and different study design may be required to confirm the exact mechanisms of ADSC-CM on hair growth.

Int J Trichology 2023; 15:133-143. [PMID: 38765719 PMCID: PMC11098136 DOI: 10.4103/ijt.ijt_39_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 03/09/2022] [Accepted: 06/14/2022] [Indexed: 05/22/2024] Open
Abstract
Objectives Androgenetic alopecia (AGA) is the most common cause of hair loss in men and women, affecting about 30% of men and 15% of women at 30 years and 80% and 48% at 70 years, respectively. This study aims to assess the effectiveness of growth factor cocktail therapy including fibroblast growth factor 9 (FGF9) (Cellcurin) in men and women with AGA. Materials and Methods This is a single-center randomized controlled trial, conducted with 10 men and 10 women with AGA. Eight men participated in the therapeutic group and two men in the control group. Eight women participated in the therapeutic group and two women in the control group. All were classified by sex, age, duration, and degrees of progression of AGA. The study obtained approval from the Research Ethics Committee (REC) of the Federal University of Uberlandia at approval number: 36918620.8.0000.5152. Six microneedling sessions were performed with an electromedical pen with an interval of 15 days between sessions. In the therapeutic group, sterile injectable Cellcurin was used and, in the control group, injectable sterile minoxidil 5 mg/ml 2 ml, both through the drug delivery system. Trichoscopic photos were taken before and after 12 weeks in the frontal and vertex regions. Descriptive statistics were performed using the t-test with the IBM SPSS-25 software. Results Men and women showed an expressive and significant increase in the amount of hair per cm2 after Cellcurin therapy, as well as an increase in the amount of terminal hair, vellus hair, sum of the terminal hair diameters, and mean of the terminal hair diameters in both regions, frontal and vertex. Conclusions In this study, we demonstrated that the use of Cellcurin in the treatment of AGA in men and women is associated with an increase in the amount of hair per cm2, in the amount of terminal hair per cm2, in the amount of vellus hair per cm2, in the number obtained by the sum of the terminal hair diameters per cm2, as well as an increase in the mean diameter of the terminal hairs.

Adipose Mesenchymal Stromal Cell-Derived Exosomes Carrying MiR-122-5p Antagonize the Inhibitory Effect of Dihydrotestosterone on Hair Follicles by Targeting the TGF-β1/SMAD3 Signaling Pathway. Int J Mol Sci 2023; 24:ijms24065703. [PMID: 36982775 PMCID: PMC10059832 DOI: 10.3390/ijms24065703] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Revised: 01/20/2023] [Accepted: 01/31/2023] [Indexed: 03/19/2023] Open
Abstract
Androgenic alopecia (AGA) is the most common type of hair loss, where local high concentrations of dihydrotestosterone (DHT) in the scalp cause progressive shrinkage of the hair follicles, eventually contributing to hair loss. Due to the limitations of existing methods to treat AGA, the use of multi-origin mesenchymal stromal cell-derived exosomes has been proposed. However, the functions and mechanisms of action of exosomes secreted by adipose mesenchymal stromal cells (ADSCs-Exos) in AGA are still unclear. Using Cell Counting Kit-8 (CCK8) analysis, immunofluorescence staining, scratch assays, and Western blotting, it was found that ADSC-Exos contributed to the proliferation, migration, and differentiation of dermal papilla cells (DPCs) and up-regulated the expression of cyclin, β-catenin, versican, and BMP2. ADSC-Exos also mitigated the inhibitory effects of DHT on DPCs and down-regulated transforming growth factor-beta1 (TGF-β1) and its downstream genes. Moreover, high-throughput miRNA sequencing and bioinformatics analysis identified 225 genes that were co-expressed in ADSC-Exos; of these, miR-122-5p was highly enriched and was found by luciferase assays to target SMAD3. ADSC-Exos carrying miR-122-5p antagonized DHT inhibition of hair follicles, up-regulated the expression of β-catenin and versican in vivo and in vitro, restored hair bulb size and dermal thickness, and promoted the normal growth of hair follicles. So, ADSC-Exos enhanced the regeneration of hair follicles in AGA through the action of miR-122-5p and the inhibition of the TGF-β/SMAD3 axis. These results suggest a novel treatment option for the treatment of AGA.

Abstract
While current studies have supported oral minoxidil as a novel, adjunctive therapy in non-scarring forms of alopecia, there continues to be limited data on oral minoxidil for these conditions. To assess oral minoxidil use in the treatment of androgenetic alopecia and telogen effluvium, a multi-center, retrospective analysis was conducted in 105 adult patients treated for androgenetic alopecia and/or telogen effluvium with oral minoxidil (dose range 0.625-2.5 mg) once daily for ≥ 52 weeks, case matched by age (± 5 years) and gender with 105 controls with androgenetic alopecia and/or telogen effluvium who were not treated with oral minoxidil. 80 women (76.2%) with a mean age of 57.5 ± 13.56 (range 24-80) and 25 men (23.8%) with a mean age of 40.4 ± 13.79 (range 19-63) were included. Efficacy was evaluated based on provider assessment of clinical response and clinical photographic evaluation using a 3-point scale (worsening, stabilization, and improvement). 52.4% of patients demonstrated clinical improvement and 42.9% demonstrated stabilization. There was a significant difference in clinical response between the patient and control group, p < 0.001. Retrospective study design. These results suggest that oral minoxidil can be an effective treatment in androgenetic alopecia and telogen effluvium.

Abstract
The barrier function of the skin is mainly assured by its outermost layer, stratum corneum (SC). One key aspect in predicting dermal drug delivery and in safety assessment of skin exposure to chemicals is the need to determine the amount of chemical that is taken up into the SC. We here present a strategy that allows for direct measures of the amount of various solid chemicals that can be dissolved in the SC in any environmental relative humidity (RH). A main advantage of the presented method is that it distinguishes between molecules that are dissolved within the SC and molecules that are not dissolved but might be present at, for example, the skin surface. In addition, the method allows for studies of uptake of hydrophobic chemicals without the need to use organic solvents. The strategy relies on the differences in the molecular properties of the added molecules in the dissolved and the excess states, employing detection methods that act as a dynamic filter to spot only one of the fractions, either the dissolved molecules or the excess solid molecules. By measuring the solubility in SC and delipidized SC at the same RHs, the same method can be used to estimate the distribution of the added chemical between the extracellular lipids and corneocytes at different hydration conditions. The solubility in porcine SC is shown to vary with hydration, which has implications for the molecular uptake and transport across the skin. The findings highlight the importance of assessing the chemical uptake at hydration conditions relevant to the specific applications. The methodology presented in this study can also be generalized to study the solubility and partitioning of chemicals in other heterogeneous materials with complex composition and structure.

Abstract
Cardiometabolic disorders (CMD) is a constellation of metabolic predisposing factors for atherosclerosis such as insulin resistance (IR) or diabetes mellitus (DM), systemic hypertension, central obesity, and dyslipidemia. Cardiometabolic diseases (CMDs) continue to be the leading cause of mortality in both developed and developing nations, accounting for over 32% of all fatalities globally each year. Furthermore, dyslipidemia, angina, arrhythmia, heart failure, myocardial infarction (MI), and diabetes mellitus are the major causes of death, accounting for an estimated 19 million deaths in 2012. CVDs will kill more than 23 million individuals each year by 2030. Nonetheless, new drug development (NDD) in CMDs has been increasingly difficult in recent decades due to increased costs and a lower success rate. Drug repositioning in CMDs looks promising in this scenario for launching current medicines for new therapeutic indications. Repositioning is an ancient method that dates back to the 1960s and is mostly based on coincidental findings during medication trials. One significant advantage of repositioning is that the drug's safety profile is well known, lowering the odds of failure owing to undesirable toxic effects. Furthermore, repositioning takes less time and money than NDD. Given these facts, pharmaceutical corporations are becoming more interested in medication repositioning. In this follow-up, we discussed the notion of repositioning and provided some examples of repositioned medications in cardiometabolic disorders.

Abstract
This study aimed to develop microemulsions using poloxamer 124 as a surfactant to improve the skin penetration of finasteride and to investigate the skin penetration pathways of these microemulsions by colocalization techniques using confocal laser scanning microscopy (CLSM). The prepared finasteride-loaded microemulsions had average particle sizes ranging from 80.09 to 136.97 nm with particle size distributions within acceptable ranges and exhibited negative surface charges. The obtained microemulsions could significantly increase the skin penetration of finasteride compared to a finasteride solution. According to the skin penetration pathway evaluation conducted with CLSM, the microemulsions were hair follicle-targeted formulations due to penetration via the transfollicular pathway as a major skin penetration pathway. Additionally, this study found that the microemulsions also penetrated via the intercluster pathway more than via the intercellular pathway and transcellular pathway. The intercluster pathway, intercellular pathway, and transcellular pathway were considered only minor pathways.

Abstract
Caffeic acid derivatives containing amide moieties similar to those of finasteride and dutasteride were synthesized. An in vitro inhibitory activity evaluation of caffeic acid (1) and its amide derivatives (2 - 4) against the steroid 5α-reductase type 1 (SRD5A1) produced by human keratinocyte cells coupled with the non-radioactive high-performance thin-layer chromatography detection revealed that caffeic acid N-[3,5-bis(trifluoromethyl)phenyl] amide (4) was a promising non-steroidal suppressor, with a half-maximal inhibitory concentration (IC50) of 1.44 ± 0.13 µM and relatively low cytotoxicity with an IC50 of 29.99 ± 8.69 µM. The regulatory role of compound 4 against SRD5A1 involved both suppression of SRD5A1 expression and mixed mode SRD5A1 inhibition. The Ki value of compound 4 was 2.382 µM based on the whole-cell kinetic studies under specific conditions. Molecular docking and molecular dynamics simulations with AlphaFold generated the human SRD5A1 structure and confirmed the stability of compound 4 at the SRD5A1 catalytic site with greater interactions, including hydrogen bonding of the key M119 amino-acid residue than those of finasteride and dutasteride. Thus, compound 4 shows the potential for further development as an SRD5A1 suppressor for androgenic alopecia treatment.

Abstract
INTRODUCTION Miniaturization of the hair follicles is evident on the balding scalp. Approved medications, topical minoxidil, and oral finasteride for the treatment of alopecia sometimes come with undesirable adverse effects. The study was to examine the bioactivity of medicinal plants for finding the promising source of anti-hair loss application. METHODS Ten ethanolic extracts were prepared from Acacia concina (Willd.) DC., Acanthus ebracteatus Vahl, Bridelia ovata Decne, Cleome viscosa L., Cocos nucifera L., Hibiscus subdariffla L., Oryza sativa L., Terminalia chebula Retz., Tinospora crispa (L.) Hook. f. & Thomson and cytotoxic tested on dermal papilla cells using MTT assay. The effect of the extracts on cell cycle was also determined using flow cytometry technique. Anti-inflammatory activity was examined by determining IL-1β inhibition in RAW 257.4 cells. In vitro study of androgenic and 5α-reductase inhibitory activities were also determined using MTT assay and enzymatic reaction couple with liquid chromatography-mass spectrometry (LC-MS), respectively. RESULTS Our results revealed that only A. ebracteatus promoted dermal papilla cell proliferation and the S and G2/M phases in cell cycle. A. ebracteatus also showed inhibitory activity against 5α-reductase and testosterone in reducing cell viability of the dermal papilla. Moreover, A. ebracteatus extract strongly inhibited LPS-stimulating IL-1β production in RAW 264.7 cells in a dose-dependent manner. CONCLUSION Our finding indicated that the ethanolic extract of A. ebracteatus is a promising candidate for anti-hair loss treatment.

Abstract
BACKGROUND Hair loss is affecting over half of the population worldwide, leading to noticeable psychotic disorders in a considerable proportion of patients. The current treatments remain unpredictable and disappointing. OBJECTIVE This study aimed to evaluate the efficacy and safety of fractional lasers compared with other conventional treatments as either mono or combined therapy in the treatment of alopecia. METHODS We have conducted a thorough literature search in PubMed, Web of Science, Embase, Cochrane library, and China national knowledge infrastructure databases (from inception to February 9, 2022). Relevant clinical trials, mainly randomized controlled trials, were included, regardless of their comparisons. The Cochrane risk of bias assessment was used for quality appraisal. Outcomes were evaluated by efficiency rate, hair density, etc. RESULTS: Thirteen controlled clinical trials, including nine randomized controlled trials, with 606 patients were retrieved. As an individual therapy, the fractional laser is superior to any other therapy in total efficiency (RR = 1.58, 95% CI: 1.16-2.14, p = 0.003). When the fractional laser was applied in combined treatments, the result showed a significant difference (RR = 1.23, 95%CI: 1.02 to 1.49, P = 0.03) compared with other treatments. Although both mono and adjunctive groups were confirmed to be efficient, there were no statistical differences between the two of them (RR = 1.24, 95% CI: 0.87-1.77, p = 0.24). CONCLUSION Our results showed that the fractional laser has a significant efficacy as either mono or adjuvant therapy. Further research and exploration of fractional lasers with larger sample sizes are required to confirm the efficiency and safety of this treatment.

The Hair Growth-Promoting Effect of Gardenia florida Fruit Extract and Its Molecular Regulation. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:8498974. [PMID: 36193135 PMCID: PMC9526658 DOI: 10.1155/2022/8498974] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 08/04/2022] [Accepted: 08/18/2022] [Indexed: 11/18/2022]
Abstract
As a herbal medicine, the extract from the fruits of Gardenia florida has been widely used for its antioxidative, hypoglycemic, and anti-inflammatory properties. However, whether G. florida fruit extract (GFFE) regulates hair growth has been rarely studied. This study was the first application of GFFE on hair growth both in vitro (human dermal papilla cells, hDPCs) and in vivo (C57BL/6 mice). The effects of GFFE on cell proliferation and hair growth-associated gene expression in hDPCs were examined. Moreover, GFFE was applied topically on the hair-shaved skin of male C57BL/6 mice, the hair length was measured, and the skin histological profile was investigated. GFFE promoted the proliferation of hDPCs and significantly stimulated hair growth-promoting genes, including vascular endothelial growth factor (VEGF) and Wnt/β-catenin signals, but suppressed the expression of the hair loss-related gene transforming growth factor-β1 (TGF-β). Furthermore, GFFE treatment resulted in a significant increase in the number, size, and depth of cultured hair follicles and stimulated the growth of hair with local effects in mice. In summary, the results provided the preclinical data to support the much potential use of the natural product GFFE as a promising agent for hair growth.

Abstract
Background: The amount of data available online is constantly increasing, including search behavior and tracking trends in domains such as Google. Analyzing the data helps to predict patient needs and epidemiological events more accurately. Our study aimed to identify dermatology-related terms that occur seasonally and any search anomalies during the SARS-CoV-2 pandemic. Methods: The data were gathered using Google Trends, with 69 entries between January-2010 and December-2020 analyzed. We conducted the Seasonal Mann–Kendal Test to determine the strength of trends. The month with the highest seasonal component (RSV) and the lowest seasonal component (RSV) was indicated for every keyword. Groups of keywords occurring together regularly at specific periods of the year were shown. Results: We found that some topics were seasonally searched in winter (e.g., herpes, scabies, candida) and others in summer (e.g., erythema, warts, urticaria). Conclusions: Interestingly, downward trends in searches on sexually transmitted diseases in comparison with increased infection rates reported officially show a strong need for improved sexual education in Poland. There were no significant differences in trends for coronavirus-related cutaneous symptoms during 2020. We have shown that the seasonality of dermatologically related terms searched in Poland via Google did not differ significantly during SARS-CoV-2 pandemic.

Abstract
Alopecia or hair loss is a widespread issue that has significant effects on personal well-being for both genders nationally and internationally. In addition, alopecia causes extreme emotional stress and negatively impacts the psychological health and self-esteem of cancer patients suffering from chemotherapy-induced alopecia. Unfortunately, available synthetic medications are costly, invasive, or have extreme adverse effects. On the contrary, natural and herbal hair loss products are widely available in the local and international markets in variable pharmaceutical forms with different mechanisms of action, namely, androgen antagonists, nutritional supplements, vasodilators, and 5α-reductase inhibitors or dihydrotestosterone blockers. Thus, it is of great importance to encourage researchers to investigate these natural alternatives that can act as potent therapeutic agents having diverse mechanisms of action as well as limited side effects. Currently, natural remedies are considered a fast-rising pharmaceutical segment with demand from a wide range of consumers. In this study, we present a review of reported herbal remedies and herb combinations recommended for hair loss and their mode of action, along with an overview of available market products and formulations, their composition, and declared effects. In addition, a general outline of the different forms of alopecia, its causes, and recommended treatments are mentioned as well. This was all done with the aim of assisting further studies with developing standardized natural formulations for alopecia as many were found to lack standardization of their bioactive ingredients and efficiency confirmation.

Abstract
The understanding of therapeutic properties is important in drug repositioning and drug discovery. However, chemical or clinical trials are expensive and inefficient to characterize the therapeutic properties of drugs. Recently, artificial intelligence (AI)-assisted algorithms have received extensive attention for discovering the potential therapeutic properties of drugs and speeding up drug development. In this study, we propose a new method based on GraphSAGE and clustering constraints (DRGCC) to investigate the potential therapeutic properties of drugs for drug repositioning. First, the drug structure features and disease symptom features are extracted. Second, the drug–drug interaction network and disease similarity network are constructed according to the drug–gene and disease–gene relationships. Matrix factorization is adopted to extract the clustering features of networks. Then, all the features are fed to the GraphSAGE to predict new associations between existing drugs and diseases. Benchmark comparisons on two different datasets show that our method has reliable predictive performance and outperforms other six competing. We have also conducted case studies on existing drugs and diseases and aimed to predict drugs that may be effective for the novel coronavirus disease 2019 (COVID-19). Among the predicted anti-COVID-19 drug candidates, some drugs are being clinically studied by pharmacologists, and their binding sites to COVID-19-related protein receptors have been found via the molecular docking technology.

Abstract
A decline in quality of life in men with androgenetic alopecia (AGA) is frequently reported, so we aimed to evaluate the psychosocial burden related to AGA in Polish male patients with AGA. We enrolled 75 adult patients with AGA. The study was conducted in an outpatient dermatology clinic in Poland. Each participant answered 23 dedicated questions about demographic data, history of the disease, and a psychosocial condition. Overall, 38.7% of patients did not notice any impact of AGA on their contact with other people or activity in their free time; 50.7% of patients observed little or no effect on their relationship with their partner; 60% of patients often or sometimes felt embarrassed by their baldness (mainly those aged 18–25 years; p=0.002); 66.7% of patients reported a rather large negative impact on their self-esteem; and 81.3% of patients sometimes experienced stress in everyday life. We conclude that AGA impairs the emotional condition and social functioning of men of all ages, but particularly of younger men. Broader interventions should be planned to allow access to a psychological and psychosocial support, starting treatment at an early stage of the disease, and involving family physicians in the treatment of AGA.

Abstract
Platelet-rich plasma (PRP) represents a novel therapy tested and is used more and more frequently in dermatology and cosmetic surgery for a variety of conditions, including androgenic alopecia (AGA), a common condition with a complex pathogenesis involving genetic factors, hormonal status and inflammation. We performed an extensive literature search which retrieved 15 clinical trials concerning the use in AGA of PRP therapy, alone or in combination, in male, female or mixed patient groups. A quantitative statistical meta-analysis of n = 17 trial groups proved significant increases in hair density from 141.9 ± 108.2 to 177.5 ± 129.7 hairs/cm2 (mean ± SD) following PRP (p = 0.0004). To the best of our knowledge, this is the first meta-analysis that proved a statistically significant correlation between the number of PRP treatments per month and the percentage change in hair density (r = 0.5, p = 0.03), as well as a negative correlation between the mean age of treatment group and the percentage change in hair density (r = −0.56, p = 0.016). Other factors considered for analysis were the PRP preparation method, amount used per treatment, hair diameter, terminal hairs and pull test. We conclude that PRP represents a valuable and effective therapy for AGA in both males and females if patients are rigorously selected.

Abstract
Androgenetic alopecia (AGA), also known as male pattern baldness, is associated with androgen and androgen receptor (AR) signaling; however, the pathogenesis of AGA remains largely unknown. Here, we demonstrate that nuclear localization of androgen receptor is elevated in the dermal papilla (DP) of balding scalp from patients with AGA. Transcriptome analysis identifies microvascular abnormalities in the DP of balding scalp compared to non-balding scalp of AGA patients. We provide further evidence that blood vessels regress in the DP of balding scalp at the early stage of hair follicle miniaturization in AGA development. Consistently, we find that microvascular vessels accumulate around the dermal papilla upon anagen initiation, and angiogenesis is required for hair regeneration in mice. Mechanistically, we show that AR-mediated paracrine signaling, mainly TGF-β signaling, from DP cells induces apoptosis of microvascular endothelial cells in the DP of balding scalp of AGA. These findings define a role of AR-mediated regression of blood vessels in DP in AGA and support the notion that early anti-AR treatment is better than late treatment.

Abstract
Pattern hair loss (PHL) is a condition that worsens with time and the only way it can be slowed down is with pharmacological intervention. Pharmacological treatments for PHL, from an evidenced-based perspective with respect to safety and efficacy, are limited to only two drugs, minoxidil and finasteride. However, there are a host of drugs being used, off-label with limited evidence. This article attempts to review the literature on this topic, and the authors add to this, with their experience of over two decades on incorporating pharmacologic treatments along with hair transplantation in their management of PHL.

Abstract
Introduction: Alopecia (hair loss) commonly affects patients and can severely affect one's confidence and self-esteem. In addition to medical therapy, hair filler fibers can improve the gross appearance of thinning hair in a targeted manner by making hair appear fuller and thicker. The objective of this study is to assess patient use, satisfaction, and adverse effects following the application of a commercially available hair fiber filler product. Materials and Methods: This cross-sectional study was conducted at an academic tertiary dermatology center. Alopecia patients were supplied a keratin hair fiber filler, which best matched their natural hair color. Following 90 days of application, patients were asked to complete questionnaires to assess patient satisfaction and record patient-reported adverse events. Results: Twenty women and 20 men with hair loss participated. Patients reported improved hair volume and increased perceptions of confidence and attractiveness after applying fiber. Most subjects (92.5%) reported a high level of satisfaction with the fiber's ability to match hair color and provide sufficient coverage. No serious adverse effects were reported. Conclusion: Alopecia has a negative impact on quality of life and several psychological domains. Topical hair filler fiber can serve as an effective and safe camouflage for patients with alopecia with high user satisfaction.

Abstract
Bee venom (BV) is a typical toxin secreted by stingers of honeybee workers. BV and BV therapy have long been attractive to different cultures, with extensive studies during recent decades. Nowadays, BV is applied to combat several skin diseases, such as atopic dermatitis, acne vulgaris, alopecia, vitiligo, and psoriasis. BV is used extensively in topical preparations as cosmetics and used as dressing for wound healing, as well as in facemasks. Nevertheless, the safety of BV as a therapeutic choice has always been a concern due to the immune system reaction in some people due to BV use. The documented unfavorable impact is explained by the fact that the skin reactions to BV might expand to excessive immunological responses, including anaphylaxis, that typically resolve over numerous days. This review aims to address bee venom therapeutic uses in skin cosmetics.

The aim of the research. To expand the knowledge about immunohistochemical changes in female patients with androgenetic alopecia (AGA) focusing on non-androgenic co-factors of pathogenesis of the disease, as this may serve as a basis for improving therapeutic regimens.
Materials and methods. Scalp biopsies of female patients with androgenetic alopecia were examined by immunohistochemical method. The study included two groups: the main group of 30 female patients aged 22 to 40 years, average age 32,13±5,03 years, and the control group that included 20 skin samples from women aged 25–40 years (average age 34,75±4,19 years) who underwent autopsies.
Results. It was found that AGA in women is characterized by a number of immunomorphological manifestations: the inflammatory infiltrate that consists of immunocompetent T-lymphocytes CD3+, CD4+ and CD8+, macrophages (CD68+); imbalance of growth polypeptides VEGF, TGF-β1, EGFR; accumulation of oxidative stress enzymes eNOS and iNOS; accumulation of pathological fraction of Collagen IV.
Conclusions. The data obtained by this study helps to improve the concept of morphogenesis of AGA, and also can become a base to improve the standards of treatment of the disease. The pathological triade “oxidative stress-microinflammation- fibrosis” should be considered as a possible treatment target, as well as the imbalance of growth peptides.

Lu Q, Gao Y, Fan Z, Xiao X, Chen Y, Si Y, Kong D, Wang S, Liao M, Chen X, Wang X, Chu W. Amphiregulin promotes hair regeneration of skin-derived precursors via the PI3K and MAPK pathways. Cell Prolif 2021; 54:e13106. [PMID: 34382262 PMCID: PMC8450126 DOI: 10.1111/cpr.13106] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 07/16/2021] [Accepted: 07/17/2021] [Indexed: 12/13/2022] Open
Abstract
Objectives There are significant clinical challenges associated with alopecia treatment, including poor efficiency of related drugs and insufficient hair follicles (HFs) for transplantation. Skin‐derived precursors (SKPs) exhibit great potential as stem cell‐based therapies for hair regeneration; however, the proliferation and hair‐inducing capacity of SKPs gradually decrease during culturing. Materials and Methods We describe a 3D co‐culture system accompanied by kyoto encyclopaedia of genes and genomes and gene ontology enrichment analyses to determine the key factors and pathways that enhance SKP stemness and verified using alkaline phosphatase assays, Ki‐67 staining, HF reconstitution, Western blot and immunofluorescence staining. The upregulated genes were confirmed utilizing corresponding recombinant protein or small‐interfering RNA silencing in vitro, as well as the evaluation of telogen‐to‐anagen transition and HF reconstitution in vivo. Results The 3D co‐culture system revealed that epidermal stem cells and adipose‐derived stem cells enhanced SKP proliferation and HF regeneration capacity by amphiregulin (AREG), with the promoted stemness allowing SKPs to gain an earlier telogen‐to‐anagen transition and high‐efficiency HF reconstitution. By contrast, inhibitors of the phosphoinositide 3‐kinase (PI3K) and mitogen‐activated protein kinase (MAPK) pathways downstream of AREG signalling resulted in diametrically opposite activities. Conclusions By exploiting a 3D co‐culture model, we determined that AREG promoted SKP stemness by enhancing both proliferation and hair‐inducing capacity through the PI3K and MAPK pathways. These findings suggest AREG therapy as a potentially promising approach for treating alopecia.

Sulforaphane, L-Menthol, and Dexpanthenol as a Novel Active Cosmetic Ingredient Composition for Relieving Hair Loss Symptoms. COSMETICS 2021.

Abstract
Sulforaphane increases the expression of the dihydrotestosterone (DHT)-degrading enzyme, 3α-hydroxysteroid dehydrogenase (3α-HSD) in the liver, which accelerates DHT degradation, thereby inhibiting hair loss in the animal model. In this study, we elucidated its underlying mechanism and demonstrated that sulforaphane has hair loss inhibitory functions in RAW264.7 macrophage cells and Hepa1c1c7 cells at the cellular and gene levels. The gene expression level of an isoform of 3α-HSD, Akr1c2, increased in a dose-dependent manner when these cells were treated with sulforaphane, but there were no significant differences at the gene levels of Akr1c2 and Dhrs9 for the negative control mixture of biotin, dexpanthenol, and L-menthol. These studies indicated that sulforaphane is involved in regulating the gene expression of Akr1c2. To further determine whether this hair product has effects on alleviating hair loss symptoms, clinical trials were also conducted for 18 weeks. We performed a visual evaluation of the parietal and frontal lines of 23 patients before and after using the product, and then calculated the total number of hairs. This clinical study showed that the parietal lines and bangs visually improved and the number of hairs increased by 6.71% from before using the test product to 18 weeks after using the test product. Taken together, these cellular and clinical studies strongly suggest that sulforaphane may be an active ingredient that significantly alleviates hair loss symptoms.

Abstract
Drug development is a complicated, slow and expensive process with high failure rates. One strategy to mitigate these factors is to recycle existing drugs with viable safety profiles and have gained Food and Drug Administration approval following extensive clinical trials. Cardiovascular and neurodegenerative diseases are difficult to treat, and there exist few effective therapeutics, necessitating the development of new, more efficacious drugs. Recent scientific studies have led to a mechanistic understanding of heart and brain disease progression, which has led researchers to assess myriad drugs for their potential as pharmacological treatments for these ailments. The focus of this review is to survey strategies for the selection of drug repurposing candidates and provide representative case studies where drug repurposing strategies were used to discover therapeutics for cardiovascular and neurodegenerative diseases, with a focus on anti-inflammatory processes where new drug alternatives are needed.

Abstract
Hair loss (HL) is a common chronic problem of poorly defined etiology. Herein, we explored the functionality of bone marrow-derived mesenchymal stem cell (BMSC) and conditioned medium (MSC-CM) as regulators of hair follicle proliferation and regeneration, and the mechanistic basis for such activity. BMSC were cultured and identified in vitro through the induction of multilineage differentiation and the use of a CCK-8 kit. The dorsal skin of mice was then injected with BMSC and MSC-CM, and the impact of these injections on hair cycle transition and hair follicle stem cell (HFSC) proliferation was then evaluated via hematoxylin and eosin (H&E) staining and immunofluorescent (IF) staining. We then conducted a tandem mass tags (TMT)-based quantitative proteomic analysis of control mice and mice treated with BMSC or MSC-CM to identify differentially expressed proteins (DEPs) associated with these treatments. Parallel reaction monitoring (PRM) was utilized as a means of verifying our proteomic analysis results. Herein, we found that BMSC and MSC-CM injection resulted in the transition of telogen hair follicles to anagen hair follicles, and we observed the enhanced proliferation of HFSCs positive for Krt15 and Sox9. Our TMT analyses identified 1,060 and 770 DEPs (fold change>1.2 or<0.83 and p < 0.05) when comparing the BMSC vs. control and MSC-CM vs. control groups, respectively. Subsequent PRM validation of 14 selected DEPs confirmed these findings, and led to the identification of Stmn1, Ncapd2, Krt25, and Ctps1 as hub DEPs in a protein-protein interaction network. Together, these data suggest that BMSC and MSC-CM treatment can promote the proliferation of HFSCs, thereby facilitating hair follicle regeneration. Our proteomics analyses further indicate that Krt25, Cpm, Stmn1, and Mb may play central roles in hair follicle transition in this context and may represent viable clinical targets for the treatment of HL.

Abstract
The anti-inflammatory, thrombolytic, and hair growth-promoting activity of the n-hexane fraction from the methanol extract of Leea indica (NFLI) leaves was investigated. NFLI showed significant inhibition of hemolysis and protein denaturation, and exhibited a concentration-dependent thrombolytic activity. When applied topically to mice at concentrations of 10, 1, 0.1%, NFLI demonstrated a significant increase in average hair length (p < 0.001) compared with untreated animals. NFLI (1% concentration) exhibited the highest percentage of hair regrowth on day 7, 14 and 21 (81.24, 65.60, and 62.5%, respectively). An in silico study was further conducted to predict the binding affinity of phytochemicals previously reported in L. indica towards PGD2 synthase (PDB ID: 2VD1), an enzyme that catalyses the isomerisation of prostaglandin H2 to PGD2 which is involved in hair loss. Phthalic acid, farnesol, n-tricosane, n-tetracosane, and n-heptacosane showed the best ligand efficiencies towards PGD2 synthase and their intermolecular interactions were visualised using BIOVIA Discovery Studio Visualizer. Our results indicate that L. indica could represent a promising natural alternative to tackle alopecia.

Abstract
Alopecia is a clinical condition related to hair loss that can significantly affect both male and female adults' quality of life. Despite the high market demand, only few drugs are currently approved for alopecia treatment. Topical formulations still bring drawbacks, such as scalp irritation with frequent use, and low drug absorption to the site of action, which limits the efficacy. The most recent research points out that different formulation technology could circumvent the aforementioned flaws. Such technology includes incorporation of drugs in rigid or deformable nanoparticles, strategies involving physical, energetical and mechanical techniques, such as iontophoresis, sonophoresis, microneedling, and the use of solid effervescent granules to be hydrated at the moment of application in the scalp. In this paper, the progress of current research on topical formulations dedicated to the treatment of alopecia is reviewed and discussed.

Abstract
BACKGROUND Androgenic alopecia (AGA) is the most common type of hair loss, in which dihyrotestosterone (DHT) plays a crucial role via modulating androgen receptors in hair follicles. AIMS The current objective is to search for new therapy of AGA. METHODS In the present study, we investigated the effects of sulforaphane, its precursor glucosinlates and glucosinlates-enriched Brassica oleracea L.var.italic Planch extract (BOE) on the growth of hair follicle and the related matrix cell viability, as well as the possible underlying mechanisms in vitro and ex vivo. RESULTS We observed that BOE, glucosinlates, and sulforaphane can prevent the testosterone-induced inhibition of dermal papilla (DP) cells viability. BOE and sulforaphane can even hinder the testosterone-induced inhibition of HaCaT cells viability. Moreover, BOE, glucosinlates, and sulforaphane can up-regulate the cytokeratin gene expression in HaCaT cells, prevent the increase in Bax gene levels induced by testosterone in DP, and promote the growth of hair follicle of mice. These effects can be linked to the enhancement of DP and HaCaT cells activities and the prevention of the testosterone-induced cell apoptosis of DP cells. CONCLUSIONS Taken together, BOE, glucosinlates, and sulforaphane can promote the growth of hair follicle of mice and can be used as potential treatment agents for androgenic alopecia.

Abstract
Hair loss by excessive stress from work and lifestyle changes has become a growing concern, particularly among young individuals. However, most drugs for alopecia impose a plethora of side effects. We have found the powerful impact of Malva verticillata seed extracts on alleviating hair loss. This study further isolated effective chemicals in M. verticillata seed extracts by liquid silica gel column chromatography. Under the screening for the growth rate (%) of human follicles dermal papilla cells (HFDPCs), we identified linoleic acid (LA) and oleic acid in n-hexane of M. verticillate (MH)2 fraction. LA treatment activated Wnt/β-catenin signaling and induced HFDPCs growth by increasing the expression of cell cycle proteins such as cyclin D1 and cyclin-dependent kinase 2. LA treatment also increased several growth factors, such as vascular endothelial growth factor, insulin-like growth factor-1, hepatocyte growth factor, and keratinocyte growth factor, in a dose-dependent manner. Besides, LA significantly inhibited Dickkopf-related protein expression (DKK-1), a primary alopecia signaling by dihydrotestosterone. Our findings suggest that LA treatment may alleviate a testosterone-induced signaling molecule and induces HFDPCs growth by activating Wnt/β-catenin signaling.

Abstract
BACKGROUND Platelet rich plasma (PRP) has been accepted as a potential therapy for treating androgenetic alopecia (AGA). OBJECTIVE To fully clarify the underling molecular mechanisms of PRP action on hair growth and promote its clinical applications. METHODS In this study, we used mice models and protein biochip to explore the specific mechanisms of PRP regulating hair growth. Then, we performed a randomized, placebo-controlled, double-blind, half-head study of 52 AGA patients to verify the therapeutic efficacy of PRP in Chinese AGA patients. RESULTS The results confirmed that PRP treatment boosted hair regrowth, accelerated hair cycling, and the effect sustained for more than one hair cycle in mice. Protein biochip evaluation confirmed remarkably upregulated β-Catenin, PDGF, and AKT signaling and repressed p53 signaling in PRP injection group. Clinically, mean hair count, density, diameter, and anagen hair ratio in PRP group showed a significant improvement at 6 month comparing to control side. CONCLUSIONS Overall, we elucidated the specific molecular mechanism of PRP action on hair growth and proved the therapeutic efficacy and safety of PRP in Chinese AGA patients.

Abstract
BACKGROUND The conditioned media from adipocyte-derived mesenchymal stem cells-conditioned media (ADSC-CM) contains cytokines and growth factors that stimulate hair regeneration. OBJECTIVE We evaluated the efficacy and safety of human ADSC-CM treatment on patients who underwent nonablative fractional laser for the treatment of androgenetic alopecia (AGA). MATERIALS AND METHODS Thirty patients who underwent nonablative fractional laser treatment were topically administered either ADSC-CM or placebo solution. As a primary outcome, phototrichograms were taken to measure changes in hair density at each visit. In addition, global improvement scores (GISs) were compared by clinical digital photographs, which were taken at the initial and final visits, and assessed by 2 independent dermatologists. Finally, the investigator's improvement score was measured by questionnaire response during the final visit. RESULTS Hair density comparisons during the treatment period revealed that the ADSC-CM group had significantly higher final densities compared with the placebo group. The GIS of the ADSC-CM group was also significantly higher than the placebo group. Finally, no adverse effects associated with the application of ADSC-CM were noted during the study. CONCLUSION The application of ADSC-CM after nonablative fractional laser treatment accelerated increases in hair density and volume in AGA patients.

Abstract
Coincidental findings of hypertrichosis in patients on minoxidil led to the development of a topical minoxidil formulation which has been approved by the Food and Drug Administration for the treatment of female pattern hair loss, the most common cause for hair loss in women. The most common side effect of topical minoxidil is irritant contact dermatitis with the typical symptoms of itching and scaling. Most commonly, these symptoms are a result of an allergic reaction to propylene glycol, or less commonly, to minoxidil itself. We present a case of a 27-year-old woman who developed facial swelling following allergic contact dermatitis to minoxidil 5% foam.

Abstract
AIMS Synthesis of 3-(2-amino-6-arylpyrimidin-4-yl)-4-hydroxy-1-methylquinolin-2(1H)-ones and estimation their anticancer activities on HepG2 and KB cancer lines. BACKGROUND Many derivatives of quinoline-2-on have been consider to synthesize and evaluate their biological properties by organic chemists due to their various biological effects, including antibacterial, antioxidant, anti-inflammatory, anticancer activities. Quinolinepyrimidine hybrid compounds exhibited various biological activities, such as antituberculosis, antibacterial, anticancer, antifungal, etc. The connection of 4-hydroxyquinoline-2-one with 2-amino-pyrimidine could initiate the new activities. OBJECTIVE α,β-Unsaturated ketones of 3-acetyl-4-hydroxy-N-methylquinolin-2-one were prepared. Novel 2-amino-6-aryl-4-(4'-hydroxy-Nmethylquinolin- 2'-on-3'-yl)pyrimidines have been synthesized by reaction of these corresponding α,β-unsaturated ketones with guanidine hydrochloride. Human hepatocellular carcinoma HepG2 and squamous cell carcinoma KB cancer lines were used for screening their cytotoxicity. METHOD 3-Acetyl-4-hydroxy-N-methylquinolin-2-one was prepared from N-methylaniline and diethyl malonate. Reaction of (un)substituted benzaldehydes with this 4-hydroxyquinoline-2-one produced corresponding substituted α ,β-unsaturated ketones in the presence of piperidine as catalyst. 2-Amino-6-aryl-4-(4'-hydroxy-N-methylquinolin-2'-on-3'-yl)pyrimidines have been synthesized from these α,β-unsaturated ketones of 3-acetyl-4-hydroxy-N-methylquinolin-2-one by reaction of corresponding α ,β-unsaturated ketones with guanidine hydrochloride. All obtained pyrimidines were screened for anticancer activity using MTT bio-assay method. RESULT Seven substituted (E)-4-hydroxy-3-(3-(aryl)acryloyl)-1-methylquinolin-2(1H)-ones were prepared and converted to corresponding substituted 2-amino-6-aryl-4-(4'-hydroxy-N-methylquinolin-2'-on-3'-yl)pyrimidines with yields of 58-74%. All the synthesized pyrimidines were screened for their in vitro anticancer activity against human hepatocellular carcinoma HepG2 and squamous cell carcinoma KB cancer lines. Compounds 6b and 6e had the best activity in the series, with IC50 values equal to 1.32 and 1.33 μM, respectively. ADMET properties showed that compounds 6b, 6e, and 6f possessed the drug-likeness behavior. Cross-docking results indicated that residues GLN778(A), DT8(C), DT9(D), DA12(F), and DG13(F) in the binding pocket as potential ligand binding hot-spot residues for compounds 6b, 6e, and 6f. CONCLUSION New substituted 2-amino-6-aryl-4-(4'-hydroxy-N-methylquinolin-2'-on-3'-yl)pyrimidines were obtained and displayed significant inhibition against human hepatocellular carcinoma HepG2 and squamous cell carcinoma KB cancer lines.

Abstract
Topical minoxidil 5% are effective in androgenetic alopecia (AGA). Spironolactone acts as an androgen antagonist by competitively blocking androgen receptors. Studying the effect of topical minoxidil 5% gel and spironolactone gel 1% in management of AGA. The study includes 60 patients diagnosed as AGA; (group I): treated with topical minoxidil gel 5%, (group II): with topical spironolactone gel 1% and group (III) treated with combined minoxidil 5% and spironolactone 1% gel. All patients were followed up monthly throughout the treatment period. Scalp biopsy was taken before and after 12 months. In group I, the clinical response was in 90% of patients with variable degrees in improvement, in group II, the clinical response was in 80% of patients, meanwhile, in group III the clinical response was in all patients (100%). Histopathological examination of skin biopsy after treatment revealed significant increase in anagen hair on the other hand, both telogen and vellus hair was significantly decreased meanwhile, the T/V ratio was significantly increased. The results of this work revealed that topical minoxidil gel 5% and topical spironolactone gel 1% were effective in treatment of AGA, while the combination of two agents was better in treatment.

Impairment of autophagy may be associated with follicular miniaturization in androgenetic alopecia by inducing premature catagen. J Dermatol 2020; 48:289-300.

Abstract
Androgenetic alopecia is the most common form of hair loss disorder. The features of this process are shortening of the anagen phase in hair cycling and progressive miniaturization of the hair follicle. However, the mechanisms in androgenetic alopecia are still unclear, and the treatment methods are also limited. Therefore, further study on the pathogenesis and new therapies for androgenetic alopecia are urgently needed. In this study, we found that endogenous autophagy was severely impaired, accompanied by increased apoptosis in early catagen-like miniaturized hair follicles from the balding scalps of androgenetic alopecia patients. Moreover, inhibition of autophagy using 3-methyladenine could induce apoptosis, premature hair follicle regression and slow down the hair growth in organ-cultured hair follicles. Taken together, these results suggest that impairment of autophagy could be a potential mechanism in androgenetic alopecia.
