[PMID: 33802416 PMCID: PMC7931056 DOI: 10.3390/gels7010026] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Revised: 02/19/2021] [Accepted: 02/24/2021] [Indexed: 01/11/2023] Open
Abstract
Micro- and nanoemulsions are potential drug solubilizers and penetration enhancers through the high surfactant/co-surfactant content. This study aimed to evaluate the influence of minoxidil (MXD) solubilized in the microemulsions (MEs) on drug release by in vitro/ex vivo diffusion through the semi-permeable membrane Spectra/Por® (Spectrum Laboratory, Gardena, CA, USA) and porcine ear skin. Moreover, a residual amount of drug in the skin after ex vivo diffusion was evaluated. The reference MER, lecithin-containing MEL, and gelatin-containing MEG were characterized in terms of their size, polydispersity index, density, viscosity, electrical conductivity and surface tension. Based on the in vitro diffusion, it can be argued that MEL slowed down the drug release, while MER and MEG have no significant effect compared to the sample, in which propylene glycol (PG) was used as a solubilizer. Determination of the residual drug amount in the skin after 6 h of the ex vivo permeation was demonstrated as the most valuable method to evaluate the effectiveness of the ME’s application. The results indicate that the most optimal MXD permeation enhancers in alginate gel were the natural surfactants containing MEs. MXD solubilization in MEG and MEL had caused more than 5% of the drug remaining in the skin, which is almost a 1.5-fold higher amount compared to the reference gel.

Gene expression profile of human follicle dermal papilla cells in response to Camellia japonica phytoplacenta extract. FEBS Open Bio 2021; 11:633-651.

Abstract
Camellia japonica L. is a flowering tree with several medicinal and cosmetic applications. Here, we investigated the efficacy of C. japonica placenta extract (CJPE) as a potential therapeutic agent for promotion of hair growth and scalp health by using various in vitro and in vivo assays. Moreover, we performed transcriptome analysis to examine the relative expression of human follicle dermal papilla cells (HFDPC) in response to CJPE by RNA-sequencing (RNA-seq). In vitro assays revealed upregulation of the expression of hair growth marker genes in HFDPC after CJPE treatment. Moreover, in vivo clinical tests with 42 adult female participants showed that a solution containing 0.5% CJPE increased the moisture content of the scalp and decreased the scalp's sebum content, dead scalp keratin, and erythema. Furthermore, RNA-seq analysis revealed key genes in HFDPC which are associated with CJPE. Interestingly, genes associated with lipid metabolism and cholesterol efflux were upregulated. Genes upregulated by CJPE are associated with several hormones, including parathyroid, adrenocorticotropic hormone, α-melanocyte-stimulating hormone (alpha-MSH), and norepinephrine, which are involved in hair follicle biology. Furthermore, some upregulated genes are associated with the regulation of axon guidance. In contrast, many genes downregulated by CJPE are associated with structural components of the cytoskeleton. In addition, CJPE suppressed genes associated with muscle structure and development. Taken together, this study provides extensive evidence that CJPE may have potential as a therapeutic agent for scalp treatment and hair growth promotion.

Abstract
Ovarian cancer (OC) is the deadliest gynecologic cancer, due to late diagnosis, development of platinum resistance, and inadequate alternative therapy. It has been demonstrated that membrane ion channels play important roles in cancer processes, including cell proliferation, apoptosis, motility, and invasion. Here, we review the contribution of ion channels in the development and progression of OC, evaluating their potential in clinical management. Increased expression of voltage-gated and epithelial sodium channels has been detected in OC cells and tissues and shown to be involved in cancer proliferation and invasion. Potassium and calcium channels have been found to play a critical role in the control of cell cycle and in the resistance to apoptosis, promoting tumor growth and recurrence. Overexpression of chloride and transient receptor potential channels was found both in vitro and in vivo, supporting their contribution to OC. Furthermore, ion channels have been shown to influence the sensitivity of OC cells to neoplastic drugs, suggesting a critical role in chemotherapy resistance. The study of ion channels expression and function in OC can improve our understanding of pathophysiology and pave the way for identifying ion channels as potential targets for tumor diagnosis and treatment.

Abstract
BACKGROUND Though androgenetic alopecia (AGA) is one of the most common diseases affecting both sexes and all races, its pathogenesis is not completely clarified. The aim of this study was to investigate the role of the four major prostaglandins (PGs) (PGE2 , PGD2 , PGF2α , and PI2 or prostacyclin) in the pathogenesis of AGA in males and females. METHODS Human scalp biopsies were obtained from 30 adults (17 males and 13 females) suffering from AGA and from 30 healthy adults (18 males and 12 females). In each subject, two skin biopsies were performed, one from the frontal bald area and another one from the occipital area with normal hair growth. In the healthy group, biopsies were taken from both areas too. In each sample, all four PGs were measured. RESULTS In the patient group, PGD2 and prostacyclin or PGI2 levels were increased in bald compared to haired scalp. On the contrary, measurements of PGE2 and PGF2α showed that they were diminished in bald areas compared to haired areas. PG levels in healthy samples were comparable to the haired areas. CONCLUSION These results support that there is a fine balance between these four proteins in scalp hair follicles, and its maintenance may be crucial for hair growth. Furthermore, their receptors could be potential targets for treatment of AGA.

Sensitization to benzyl salicylate and other allergens in patients with frontal fibrosing alopecia. Contact Dermatitis 2021; 84:423-430.

Abstract
BACKGROUND Contact sensitization is frequent among patients with frontal fibrosing alopecia (FFA) (52%-76%). OBJECTIVE To evaluate the frequency of sensitization/photosensitization in an FFA population. METHODS A population of FFA patients were patch tested (Spanish Contact Dermatitis Research Group [GEIDAC] baseline; cosmetic and fragrance series), and photopatch tested (sunscreen series). RESULTS Thirty-six patients (mean age: 64.6 years; 35/36: women) were studied. A history of dermatitis was recorded in 69.4% (frequently involving the face). Overall, 80.5% patients showed positive patch-test reactions. The most frequently positive allergens were nickel sulfate (25%), benzyl salicylate (22%), gallates (16.6%), propolis (16.6%), and limonene hydroperoxides (13.8%). Benzyl salicylate was likely relevant to the dermatitis (labeled on personal care products and most patients reporting clinical improvement with allergen avoidance). Patch tests with sunscreens showed positive reactions to 11 materials (five patients). Photopatch tests were positive in one case. CONCLUSION We speculate a possible relationship between sensitization to benzyl salicylate and FFA. Hypothetically, the most likely explanation is that sensitization to benzyl salicylate involving FFA patients is a consequence of increased exposure to it. It is unclear whether allergen avoidance may impact the prognosis of alopecia. However, it seems to significantly improve the patients´ quality of life by lessening dermatitis and pruritus.

Abstract
BACKGROUND Androgenetic alopecia (AGA) is the most common form of alopecia in men. Cetirizine, a second-generation H1 blocker, is known for its anti-inflammatory properties and its ability to decrease prostaglandin D2 (PGD2) production. AIM To evaluate the efficacy and tolerability of topical cetirizine in male patients with AGA. METHODS Two groups of 30 patients each (healthy males aged between 22 and 55 years) with different grades of AGA classified according to the Hamilton-Norwood classification were recruited for this study. Group A subjects applied 1 mL of 1% topical cetirizine daily, while group B subjects served as controls and were instructed to apply 1 mL of a placebo solution for 6 months. RESULTS Dermoscopic assessment revealed significantly higher hair regrowth among the cetirizine-treated group (P < .001). The patients' satisfaction was significantly higher among the cetirizine-treated group (P < .001). CONCLUSION The current study highlights a potential role cetirizine might have in treating AGA. It should be noted that studies are lacking in this regard and more randomized and controlled trials are warranted in order to confirm or refute such early findings.

Abstract
INTRODUCTION Androgenic alopecia (AGA) occurs due to progressive miniaturization of the dermal papilla (DP). During this process the hair follicle loses nutrition over time and eventually dies, causing the hair to fall out. Recent evidence suggests that hypoxia-inducible factor-1a (HIF-1α) modulation may counteract hair loss. This study aims to evaluate the proliferation of dermal papilla cells (DPCs) under the influence of a selection of commercially available topical hair loss drugs, compared to HIF-1α-stimulating agents. MATERIALS AND METHODS Using the hanging drop method, DPCs self-organized into spheroid shape, mirroring the three-dimensional (3D) structure of the DP in vivo. DP analogs were treated with established substances against AGA (minoxidil and caffeine) compared to HIF-1α-stimulating agents (deferoxamine [DFO] and deferiprone [DFP]), at 10 mM doses. DP analogs were simultaneously stained with 5-bromo-2'-deoxyuridine (BrdU) to evaluate impact of drug compounds on DP daughter cell production. Concurrently, fluorescent microscopy visualization of migration of daughter cells after 48 h in culture was performed. RESULTS DPC proliferation within the spheroid structure was significantly enhanced by caffeine, minoxidil, and the HIF-1α-stimulating agent DFP when compared to control. Highest proliferation was seen in the DFP-treated DP analogs. Migration of peripheral DP daughter cells was highest in control and DFO groups. CONCLUSION Here we demonstrate a significantly enhanced proliferative activity for both established substances against AGA (minoxidil and caffeine) and the HIF-1α-stimulating agent DFP in a 3D DPC spheroid culture model with equal results for DFP and minoxidil. These favorable characteristics make such compounds potential water-soluble alternatives to minoxidil.

Abstract
Male and female pattern hair loss (MPHL and FPHL, respectively), is the most common cause of hair loss affecting nearly 80 million people in the US, yet treatment options remain limited and lacking. As the need for more effective therapeutics remains unmet, this perspective offers a unique angle by directing attention to the inflammatory aspect of MPHL and FPHL. Evidence and implications of inflammation as a characteristic feature of MPHL and FPHL are highlighted through evaluation of clinical and quantitative data. Comparable results suggest the presence of significant perifollicular inflammatory infiltrates, such as lymphocytes and histiocytes, as well as the involvement of inflammatory genes, such as CASP7 and TNF, in the presentation of MPHL and FPHL. Resurfacing of the inflammatory aspect in MPHL and FPHL pathogenesis will advance future developments in MPHL and FPHL therapeutic options.

Abstract
Androgenetic alopecia (AGA) is a global challenge, affecting a large number of people worldwide. Efficacy of the existed treatments can barely meet the demands of patients. Patients who are poorly responding to those treatments are seeking for a more effective and suitable technique to treat their disease. Low-level light therapy (LLLT) is a newly developed technique, which has been proved to stimulate hair growth. Based on the function principle of LLLT in other domains and refer to the published literatures, we write this review to neaten and elucidate the possible mechanism of LLLT in the treatment of AGA. A review of published literature which is associated with keywords LLLT, photobiomodulation, AGA, treatment, hair growth, and mechanism was performed to elucidate the proposed mechanism of LLLT in the treatment of AGA. The present study shows that LLLT can accelerate hair growth in AGA patients. The proposed mechanism of LLLT in treating AGA may vary among different specialists. But we can summarize the consensual mechanisms as follows; low-level light absorbed by chromophores can lead to the production of nitric oxide (NO) and the modulation of reactive oxygen species (ROS). These mobilized molecules subsequently activate redox-related signaling pathways in hair follicle cells and perifollicular cells. Finally, these activated cells participate in the regrowth of hair follicle. Even though the efficacy of LLLT in the treatment of AGA in both men and women has already been confirmed, the present studies focusing on discovering LLLT are still inadequate and unsystematic. More studies are needed to standardize the optimum treatment parameters applied in promoting hair growth and determine the long-term safety and efficacy of LLLT. Current recognitions about the mechanisms of LLLT, mainly focused on the molecules that may take effect, neglected different cellular components that are functional in the hair follicle macro-environment.

Abstract
Although thinning hair and alopecia are not recognized as severe diseases, hair loss has implications for mental health and quality of life; therefore, a large number of studies have been carried out to develop novel hair growth agents. In the present study, we aimed to examine the potential of telomerase reverse transcriptase (TERT), because TERT overexpression in skin activates resting hair follicle bulge stem cells, which triggers initiation of a new hair follicle growth phase and promotes hair synthesis. To this end, we screened polyphenols that activate TERT expression in keratinocytes, and identified resveratrol and fisetin as strong hTERT-augmenting compounds. These polyphenols also regulated the gene expression of cytokines such as IGF-1 and KGF, which activate the β-catenin pathway, and TGF-β1, which plays an important role in maintaining the niche of hair follicle stem cells, thus are thought to play roles in promoting hair growth. We additionally showed that these polyphenols, especially fisetin, promoted hair growth from the shaved dorsal skin of mice, which suggests that these polyphenols activate the transition from telogen to anagen phase. Histological studies indicated that the dorsal skin of mice treated with these polyphenols contained numerous hair follicles and was thickened compared with that in control mice. Furthermore, on the dorsal skin of mice treated with resveratrol and fisetin, a number of proliferating cells (Ki67+ cells) were observed around the hair papilla. These results suggest that resveratrol and fisetin induce a shift from telogen to anagen in the hair follicle by inducing proliferation of hair follicle bulge stem cells, thus promoting hair growth.

Abstract
Androgenic alopecia (AGA) is the most common alopecia that is heritable, androgen-dependent and occurs in both sexes with defined patterns such as Male pattern hair loss in men and Female pattern hair loss in women. AGA affects at least 50 % of men by the age of 50 years, and up to 70 % of all males in later life.
The aim.The research was aimed to substantiate the optimal concentration of excipients and active pharmaceutical ingredients (APIs) of the emulgel intended for the topical treatment of androgenic alopecia.
Materials and methods. In this study the samples of the emulgel bases containing different carbomer Ultrez10 concentrationsin the range of 0.3–0.6 % and its neutralizers (0.1 % of potassium sorbate and 0 % or 0.2 % of triethanolamine) were used. Colloidal and thermal stability, pH, rheological properties (structural viscosity, mechanical stability, degree of thixotropy) of these samples were determined. The emulgel samples with different percentages of the Serenoa repens dry extract and the Sophora japonica tincture were used in the biopharmaceutical studies. The samples of the emulgel with the antioxidant butylhydroxytoluene different concentrations (0 %, 0.01 %, 0.02 %, 0.03 %) were used to determine acid value during 1 year of the emulgel storage.
Results and discussion. It was experimentally substantiated the optimal ratio of the emulgel ingredients that provide good APIs release and necessary consumer properties of the semi-solid remedy like application compliance, safety and storage stability.
Conclusions. Physicochemical, rheological and biopharmaceutical properties of emulgel bases have been studied. It was found that the base №2 (in which the concentrations of Carbomer Ultraz 10, potassium sorbate and triethanolamine are 0.3 %, 0.1 %, 0.2 % respectively) possessed the optimal properties. Considering the results of the complete range of experimental research it was developed the final formulation of the emulgel intended for AGA treatment which included the concentration of the APIs, neutralizers, preservatives, antioxidant and fragrance.

Abstract
In a healthy female reproductive system, a subtle hormonal and metabolic dance leads to repetitive cyclic changes in the ovaries and uterus, which make an effective ovulation and potential implantation of an embryo possible. However, that is not so in the case of polycystic ovary syndrome (PCOS), in which case the central mechanism responsible for entraining hormonal and metabolic rhythms during the menstrual cycle is notably disrupted. In this review we provide a detailed description of the possible scenario of PCOS pathogenesis. We begin from the analysis of how a set of genetic disorders related to PCOS leads to particular malfunctions at a molecular level (e.g., increased enzyme activities of cytochrome P450 (CYP) type 17A1 (17α-hydroxylase), 3β-HSD type II and CYP type 11A1 (side-chain cleavage enzyme) in theca cells, or changes in the expression of aquaporins in granulosa cells) and discuss further cellular- and tissue-level consequences (e.g., anovulation, elevated levels of the advanced glycation end products in ovaries), which in turn lead to the observed subsequent systemic symptoms. Since gene-editing therapy is currently out of reach, herein special emphasis is placed on discussing what kinds of drug targets and which potentially active substances seem promising for an effective medication, acting on the primary causes of PCOS on a molecular level.

Abstract
BACKGROUND Hair is an essential identity of women. Femininity, sexuality, attractiveness, and personality are symbolically linked to a woman's hair. Female pattern hair loss is found in 20%-30% of patients with polycystic ovary syndrome (PCOS). AIM The aim of the present study was to evaluate the efficacy of QR678® and QR678 Neo® therapy in the treatment of female alopecia with PCOS. METHOD A total of 20 females diagnosed with PCOS in the age 25-50 years, with complaints of female pattern alopecia with Ludwig, grades I, and II were selected for the study. At each visit, 1.5 ml solution of QR678® was injected in the scalp skin of patients. A total of eight sessions were performed at an interval of 3 week each. All the patients were evaluated with standard global photography at baseline, 4th and 8th session, and 2 months after 8th session. RESULT Marked improvement was seen in the global photographic assessment score (mean = 8) which was maintained for over 1 year. In videomicroscopic assessment, after four sessions the patients had 8.07 fewer vellus hair, 6.07 more terminal hair, and average hair shaft diameter was 0.82 μm wider. After eight sessions, they had 11.66 fewer vellus hair, 13.77 more terminal hair, and hair shaft diameter was 2.86 μm wider than at baseline. CONCLUSION Intra-dermal injections of QR 678® hair growth factor formulation is an effective option for female pattern alopecia with PCOS. This is the first of its kind study using QR678® and QR678 Neo® in PCOS patients.

Abstract
Drug-based monotherapy provides limited clinical benefits in polygenic disorders, such as androgenetic alopecia. Possible benefits must be measured against non-trivial risks of negative side effects. Several well-controlled, peer-reviewed, basic science studies have demonstrated novel mechanisms of action and potential utility for natural-based phytochemicals in the treatment of androgen-mediated disorders, including androgenetic alopecia. Yet, due to phytochemical instability, volatility, and incompatibility, the bridge from in vitro potential to clinical efficacy remains largely unmet. Recent advances in nanomaterial manipulation provide enhanced platforms, such as cyclodextrins, in which these phytochemicals may be enveloped and delivered without triggering the loss of intended function. Unexpected, positive results of an uncontrolled case series for a cyclodextrin-enabled, natural-based formula containing γ linolenic acid, β-Sitosterol, epigallocatechin gallate, and genistein, administered concomitantly via oral and topical form in two androgenetic alopecia-affected, male subjects over the course of 270 days were found. At baseline, significant baldness in the vertex scalp of both subjects was observed. Subsequent 90-day time points demonstrated marked hair thickening. On treatment day 270 (conclusion), scalp hair loss was no longer evident in either patient. Particularly in the setting of a disorders, such as androgenetic alopecia, nano-complexed, botanically-based compositions may offer beneficial adjunctives or alternatives to traditional drug-based/surgical medical treatments.

Abstract
BACKGROUND Intradermal minoxidil is used as an off-label treatment for patchy non-severe alopecia areata (AA) either alone or in combination with steroids; however, studies estimating its efficacy are still lacking. OBJECTIVES To assess the efficacy of intradermal delivery of minoxidil 5% alone and in combination with intralesional triamcinolone acetonide for treatment of patchy non-severe AA. PATIENTS AND METHODS One hundred patches in twenty patients with patchy non-severe AA, five patches for each patient, were included in this prospective intra-patient comparative controlled clinical study. Four comparative patches per each patient were randomly assigned to receive 4 sessions, at a 4-week interval, of one of the following treatments: intralesional triamcinolone acetonide, intralesional minoxidil 5%, combination treatment, or micro-needling. The fifth patch was observed as the negative control. Treatment outcomes were assessed at baseline, and 1 month after treatment ends. RESULTS Minoxidil intradermal injection was nearly comparable to the micro-needling effect and its combination to steroids had no additive effect. Hair regrowth in response to minoxidil occurred earlier than the spontaneous recovery. CONCLUSION Monotherapy of intralesional minoxidil is of limited efficacy in treating non-severe patchy AA, but it speeds the recovery.

Abstract
BACKGROUND A new propylene glycol (PG)-free 5% minoxidil (Mnx) lotion has been recently commercialized. Aim of this study was to evaluate the acceptability/tolerability and clinical efficacy of 3-month application of this new PG-free Mnx lotion and the penetration of the active compound in a reconstructed human epidermis (RHE/Episkin) model in comparison with a PG Mnx 5% lotion. METHODS Thirty subjects of both sex with a diagnosis of AGA were enrolled in the trial. Cosmetic acceptability and clinical efficacy were evaluated after 4, 8 and 12 weeks of treatment. Global tolerability was evaluated at week 12. Cosmetic acceptability evaluation was assessed using a 7-item questionnaire using a 10-point scale score. Global Tolerability was evaluated with a 4-grade scale. Clinical efficacy was evaluated with a 5-grade scale. Skin absorption of PG-free Mnx was evaluated and compared with a PG Mnx solution using the Episkin model. RESULTS All subjects concluded the study. The 7-item questionnaire mean values were always <2 at each time-point evaluation, demonstrating high cosmetic acceptability/tolerability. No subjects reported burning, itching or redness sensations. Global Tolerability score mean±SD value was 1.7±0.4. Clinical efficacy scores were 0.4, 0.6 and 1.2 at week 4, 8 and 12, respectively. PG-free Mnx showed similar amount of absorbed dose in comparison with PG Mnx. CONCLUSIONS This new PG-free lotion shows a very good cosmetic acceptability/tolerability profile. Clinical efficacy was also documented. The skin penetration of this formulation is comparable to the PG Mnx lotion, supporting the bioequivalence of the two products.

Abstract
Minoxidil is a strong arterial vasodilator, first introduced as an antihypertensive medication. In dermatology, topical minoxidil (TMX) has been used for many types of alopecia. TMX is not FDA-approved in patients under 18 years old and there are no guidelines for its pediatric use. Low-dose oral minoxidil (OMX) has been used off-label for hair loss treatment in adults expecting to achieve better therapeutic compliance and greater clinical efficacy. However, little is known about TMX and OMX in pediatric population. the literature presented on TMX and OMX in children to date was reviewed. The terms "minoxidil", "child", "children", "childhood", and "infant" were used to perform a literature search in MEDLINE through PubMed. The search was limited to articles about humans and available in English. While 25 relevant articles were selected, duplicate titles were excluded. This article pointed out the use of minoxidil in several pediatric hair diseases. Even when used topically, dermatologists should be aware of potential risks of systemic absorption. In particular situations, OMX in very low doses may be considered. To date, there are no guidelines regarding the ideal dose or minimum age for using the drug topically or systemically.

Abstract
Background: Androgenetic alopecia (AGA) is a frequently encountered dermatological concern that impacts a patient's self-esteem and quality of life. Finasteride is a selective 5-alpha reductase inhibitor that has been approved for the treatment of male AGA and the off-label use in female pattern hair loss (FPHL); however, its adverse effects may limit its use. Topical finasteride is a new formulation that aims to decrease complications caused by oral administration.Objective: This review assesses the pharmacology, current therapeutic use, and safety of topical finasteride for the treatment of AGA and FPHL.Methods: A PubMed search was conducted to include all English language articles on topical finasteride from January 1992 to January 2020.Results: A total of 33 articles including 28 topical finasteride related articles and five AGA related articles were included in this review. Multiple studies on topical finasteride as the treatment for male AGA and FPHL showed positive results with a favorable safety profile.Conclusions: Topical finasteride is a promising therapeutic option. We emphasize the importance of continued research for the establishment of a novel therapeutic agent.

Abstract
Introduction: To date no standardized hormonal treatment protocols for non-binary transgender individuals have been described in the literature and there is a lack of data regarding their efficacy and safety. Objectives: To suggest possible treatment strategies for non-binary transgender individuals with non-standardized requests and to emphasize the importance of a personalized clinical approach. Methods: A narrative review of pertinent literature on gender-affirming hormonal treatment in transgender persons was performed using PubMed. Results: New hormonal treatment regimens outside those reported in current guidelines should be considered for non-binary transgender individuals, in order to improve psychological well-being and quality of life. In the present review we suggested the use of hormonal and non-hormonal compounds, which—based on their mechanism of action—could be used in these cases depending on clients’ requests. Conclusion: Requests for an individualized hormonal treatment in non-binary transgender individuals represent a future challenge for professionals managing transgender health care. For each case, clinicians should balance the benefits and risks of a personalized non-standardized treatment, actively involving the person in decisions regarding hormonal treatment.

Abstract
Androgenic alopecia (AGA) is the most common type of progressive hair loss in man. The search for reliable predictors of the conservative treatment’s effectiveness is an urgent problem today. Forty-eight patients with AGA, stages I–IV by the Norwood–Hamilton scale, were treated for 4 months with 5% topical minoxidil joints with corrections for trace element and vitamin imbalances. In most cases, the positive therapy’s effect was shown in the parietal but not in the occipital area, whereas that effect was observed in others. The attempts to associate the therapy’s effectiveness with initially defined genetic, hormonal, and metabolic parameters showed the absence of differences between groups with positive and negative outcomes. Among the studied nutrient parameters (Zn, Cu, Mg, Ca, Fe, and Se, as well as vitamins B12, E, D, and folic acid), differences between these groups was shown in zinc content only. The starting point from a zinc plasma level above 10 µmol/L likely provides the success of the subsequent conservative therapy and correlates with an increase in the hair density and diameter in the parietal area. The integral predictive value of the Zn plasma level was assessed as 72.3% (positive predictive value: −88%; and negative predictive value: −55%).

Mesenchymal Stem/Stromal Cell-Derived Exosomes for Immunomodulatory Therapeutics and Skin Regeneration. Cells 2020; 9:E1157. [PMID: 32392899 PMCID: PMC7290908 DOI: 10.3390/cells9051157] [Citation(s) in RCA: 244] [Impact Index Per Article: 61.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 04/25/2020] [Accepted: 05/04/2020] [Indexed: 12/12/2022] Open
Abstract
Exosomes are nano-sized vesicles that serve as mediators for cell-to-cell communication. With their unique nucleic acids, proteins, and lipids cargo compositions that reflect the characteristics of producer cells, exosomes can be utilized as cell-free therapeutics. Among exosomes derived from various cellular origins, mesenchymal stem cell-derived exosomes (MSC-exosomes) have gained great attention due to their immunomodulatory and regenerative functions. Indeed, many studies have shown anti-inflammatory, anti-aging and wound healing effects of MSC-exosomes in various in vitro and in vivo models. In addition, recent advances in the field of exosome biology have enabled development of specific guidelines and quality control methods, which will ultimately lead to clinical application of exosomes. This review highlights recent studies that investigate therapeutic potential of MSC-exosomes and relevant mode of actions for skin diseases, as well as quality control measures required for development of exosome-derived therapeutics.

Abstract
Androgenetic alopecia (AGA) is a multifactorial and age-related condition characterized by substantial hair loss affecting both men and women. Conventional treatments include the use of topical minoxidil (MNX) formulations to stimulate hair growth and restore hair condition. However, those treatments are associated with limited performance and a lack of tolerability and compliance due to the emergence of adverse effects. Considering that the development of nanotechnology-based formulations as hair loss therapeutic strategies has been clearly growing, topical MNX delivery by means of these innovative formulations is known to enhance MNX skin permeation and depot formation into hair follicles, allowing for MNX-controlled release, increased MNX skin bioavailability and enhanced therapeutic efficacy with minimal adverse effects. This review highlights the potential of nanotechnology-based MNX delivery formulations for improved hair loss therapeutics, including a thorough assessment of their in vitro and in vivo performances, as well as regulatory and nanosafety considerations.

Abstract
The currently approved treatment for female pattern hair loss (FPHL) includes topical minoxidil administration; however, this treatment fails to achieve hair regrowth in some patients. Finasteride, a selective 5α-reductase inhibitor (5-ARI), may be considered as an alternative treatment. However, because of its potential teratogenic effects, clinical studies and use of finasteride for FPHL are limited. In this review, we aim to summarize the literature regarding the pharmacology, clinical efficacy, and adverse effects of oral finasteride for the treatment of FPHL and to provide novel therapeutic options including topical finasteride and dutasteride, a new generation 5-ARI, for the treatment of FPHL.

Suchonwanit P, Thammarucha S. Eyebrow growth pattern analysis in patients with eyebrow hypotrichosis after receiving topical treatment: A retrospective study. J Cosmet Dermatol 2019; 19:1404-1408. [PMID: 31541563 DOI: 10.1111/jocd.13167] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Revised: 09/04/2019] [Accepted: 09/05/2019] [Indexed: 12/25/2022]
Abstract
BACKGROUND Differences in growth patterns among the various parts of the eyebrow have been observed. AIMS We aimed to investigate changes in the hair density and diameter and analyze the eyebrow growth pattern of each eyebrow part (head, body, and tail) in patients with eyebrow hypotrichosis over a 24-week course of topical treatment. PATIENTS/METHODS A retrospective study of 48 patients who received treatment with bimatoprost 0.01% was conducted. Patient demographic data were collected; measurements of hair density and diameter in the different parts of the eyebrow were collected and statistically evaluated. RESULTS The tail of the eyebrow revealed the lowest baseline eyebrow density and diameter. Significant changes in eyebrow density (P = .01) and diameter (P = .01) were first detected in the tail at 4 and 16 weeks of treatment, respectively. The head and body showed a comparable growth pattern. CONCLUSIONS This study confirms the previous observations that hair density, diameter, pattern of growth, and hair growth cycle vary according to their anatomical location within the eyebrow. A better understanding of eyebrow growth pattern could provide the precise pathomechanism of eyebrow hypotrichosis leading to a standardized treatment protocol.
