[PMID: 36865530 PMCID: PMC9972869 DOI: 10.1002/hsr2.870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 09/06/2022] [Accepted: 09/20/2022] [Indexed: 03/04/2023] Open
Abstract
Background and Aims Psychological, behavioral, hormonal, surgical, and psychopharmacologic approaches are the only acknowledged treatments for Female Sexual Dysfunction (FSD). The study is conducted to assess the efficacy of hybrid cooperative complexes of high and low molecular weight hyaluronan (hybrid H-HA/L-HA) in treating females with varying of sexual dysfunction and to assess the female genital self-image scale (FGSIS), female sexual function index (FSFI), and dermatology life quality index (DLQI) before and after treatment. Methods Sixty female patients were divided into two groups. The study group enrolled 30 female patients injected with hybrid H-HA/L-HA, while the control group enrolled 30 female patients injected with saline. Patients were recruited from the clinic searching for medical advice. Controls were selected from close associates of the cases who were attending with the patients or healthy escorts of dermatology patients attending the dermatology outpatient clinic. We assessed socio-demographic, clinical evaluation, the (FGSIS), (FSFI), and (DLQI) before and after treatment. The first assessment was conducted at the first visit, and the second assessment was conducted after 1 month of the second injection. Result Significant increase in the frequency of sexual intercourse/week in the study group after the first and second injection sessions compared to the controls was observed (p < 0.05). There was statistically significant amelioration in desire, arousal, lubrication, orgasm, satisfaction domains, and total score of the FSFI (p ≤ 0.05). The study demonstrated significant increasing differences in all domains of the FGSIS (p ≤ 0.05). The symptoms and feelings, leisure, personal relationships, and total scores were significantly higher post first and second injection of (hybrid H-HA/L-HA) sessions compared to the controls (p < 0.05). Conclusion The (hybrid H-HA/L-HA) injection for rejuvenating the genital area appears to be a safe and effective way to enhance female genital self-image, sexuality, and quality of life with high levels of satisfaction as a minimally invasive method.

Abstract
Elastin is the main component of elastic fibers, which provide stretch, recoil, and elasticity to the skin. Normal levels of elastic fiber production, organization, and integration with other cutaneous extracellular matrix proteins, proteoglycans, and glycosaminoglycans are integral to maintaining healthy skin structure, function, and youthful appearance. Although elastin has very low turnover, its production decreases after individuals reach maturity and it is susceptible to damage from many factors. With advancing age and exposure to environmental insults, elastic fibers degrade. This degradation contributes to the loss of the skin's structural integrity; combined with subcutaneous fat loss, this results in looser, sagging skin, causing undesirable changes in appearance. The most dramatic changes occur in chronically sun-exposed skin, which displays sharply altered amounts and arrangements of cutaneous elastic fibers, decreased fine elastic fibers in the superficial dermis connecting to the epidermis, and replacement of the normal collagen-rich superficial dermis with abnormal clumps of solar elastosis material. Disruption of elastic fiber networks also leads to undesirable characteristics in wound healing, and the worsening structure and appearance of scars and stretch marks. Identifying ways to replenish elastin and elastic fibers should improve the skin's appearance, texture, resiliency, and wound-healing capabilities. However, few therapies are capable of repairing elastic fibers or substantially reorganizing the elastin/microfibril network. This review describes the clinical relevance of elastin in the context of the structure and function of healthy and aging skin, wound healing, and scars and introduces new approaches being developed to target elastin production and elastic fiber formation.

Abstract
Purpose The light-emitting diodes (LEDs) have been applied in oral surgery for tissue stimulation and wound healing. Several Authors have highlighted that fibroblasts subjected to phototherapy have an increased viability, proliferation, biomodulation of inflammatory cytokines and genes expression. It remains to be determined which are the best irradiation parameters (energy, wavelength, power) for each type of cell in order to obtain the best bio-stimulation. The aim of this study was to investigate the effects of LED irradiation on primary human gingival fibroblast cells (HGF) on DSP, ELN, HAS1, ELANE, HYAL1, RPL13 genes activation using Real Time PCR. These genes activation is directly connected with elastin protein production and HGF functionality. Materials and methods Human gingival tissue biopsies were obtained from three healthy patients during extraction of teeth. The gingival pieces were fragmented with a scalpel and transferred in culture dishes for allow the cells growth. Human gingival fibroblasts at the second passage were seeded on multiple 6-well plates and were stimulated with three different light-emitting diodes (LEDs) fixture. After irradiation, the cells were trypsinized, harvested and lysed for RNA extraction. Genes expression was quantified using Real Time PCR. Results We didn't found significant differences in genes activation of HGF of the three different LEDs. The LED irradiation seems to be directly correlated with the elastin and hyaluronoglucosaminidase 1 genes activation that are directly connected with proteins production and HGF functionality. Conclusions HGF show an increased deposition of elastin as well as enhanced expression of collagen type I, which is the main protein related to the synthesis and of the collagen-rich matrix.

Abstract
BACKGROUND An injectable medical device containing stable hybrid cooperative complexes of high- and low-molecular-weight hyaluronic acid (HA) has been developed with characteristics suited for a global improvement of facial esthetics. OBJECTIVE To evaluate the HA product performance in improving some key facial esthetic features. The study employed clinical scales, subjective evaluations, and facial skin objective measurements. METHODS A single Italian site treated 64 female subjects aged 38-60 years, with injections at five predetermined points, on each side of the face, with a 4-week time lapse between the first and the second product administration. Subjects were evaluated after 4, 8, 12, and 16 weeks, using validated clinical scales, subjective evaluation, and objective quantitative outcome measures. Assessment of esthetic results included photographic documentation. RESULTS Both the clinical and subjective assessments, and the majority of objective instrumental parameters indicated an improvement throughout the study and were already significant at week 4 or 8 and were still significant at week 16 (3 months after the second treatment). Minor and temporary local skin reactions were observed in 23% of subjects at the site of the injections, and the global judgment on tolerability was good or excellent, both in the investigators' opinion and volunteers' self-evaluation. CONCLUSION Both subjective and objective improvement of the facial parameters was consistent with the bio-remodeling purpose, and persistent and still statistically significant at the end of the study. The tolerability and safety profile of the product were judged good or excellent both by investigators and volunteers. This study supports the claim for bio-remodeling of these stable hybrid cooperative complexes of low- and high-molecular-weight HA.

Abstract
Nowadays there is a great interest in investigating the effect of particular hyaluronan fragments in the biomedical field and in cosmeceutical applications. Literature has reported that very low molecular weight HA (Mw<5kDa) has an inflammatory effect, whilst HA ranging from 15 to 250 has shown controversial effects. This work aims to give better elucidation on the correlation between the different sized HA fragments and their biological functions. In this respect, a simple and effective degradation strategy is used to obtain several HA fragments. Also, an hydrodynamic and structural characterization was performed in order to obtain samples suitable to evaluate cellular response. In particular an in vitro scratch test in time lapse experiments was used to study the effect of HA fragments, ranging from 1800 to 6kDa on wound dermal reparation based on human keratinocytes. All high and low Mw HA used in this study allowed for faster wound closure compared to the un-treated cells, except for 6kDa that, on the contrary, prevented repair. In addition, TGF-β 1, TNFα and IL-6, representative biomarkers of the inflammation phase occurring in wound healing process, were quantified by RT-PCR. A general up-regulation trend of these biomarkers was found with the HA molecular weight reduction. LHA6kDa was the only treatment that induced a major inflammatory response (over 30 fold increase respect to control) confirming the recent literature outcomes. IL-6 protein level evaluated through ELISA assay corroborated the previous results. Furthermore, activation of key HA receptors, such as CD44, RHAMM, TLR4, with respect to hyaluronan size, was evaluated, at transcriptional level showing selective recognition by HA 1800, 1400, 500 for CD44, whilst the lower Mw fragments activated TLR-4 moderately at 50 and 15kDa. An increase to "alarm" level was found for 6kDa fragments. Immunofluorescence staining confirmed this data. The present research work demonstrated that the diverse pharma grade hyaluronan fragments could modulate cellular processes differently. From 1800kDa down to 50kDa, CD44 was the recognized receptor and pro-inflammatory biomarkers were only slightly up-regulated during wound healing in the presence of HA. Finally our outcomes showed that the lower the fragment size the higher the concern for inflammatory cytokines up-regulation; repair process impairment was highlighted only for 6kDa chains.

Abstract
Mesotherapy/biorevitalization with hyaluronic acid (HA) is a treatment approach currently used for skin rejuvenation. Various products with a wide range of polycomponent formulations are available on the market. Most of these formulations contain noncross-linked HA in combination with a biorevitalization cocktail, formed by various amounts of vitamins, minerals, amino acids, nucleotides, coenzymes, and antioxidants. Although ingredients are very similar among the different products, in vitro and clinical effects may vary substantially. There is a real need for better characterization of these products in terms of their action on human skin or in vitro skin models. In this study, we analyzed the effect of the RRS® (Repairs, Refills, Stimulates) HA injectable medical device on human skin fibroblasts in vitro. Skin fibroblast viability and its capacity to induce the production of key extracellular matrix were evaluated in the presence of different concentrations of RRS HA injectable. Viability was evaluated through colorimetric MTT (3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide) assay, and key extracellular matrix genes, type I collagen and elastin, were quantified by quantitative polymerase chain reaction. Results demonstrated that RRS HA injectable could promote human skin fibroblast viability (+15%) and increase fibroblast gene expression of type I collagen and elastin by 9.7-fold and 14-fold in vitro, respectively. These results demonstrate that mesotherapy/biorevitalization products can, at least in vitro, effectively modulate human skin fibroblasts.

Abstract
BACKGROUND The "non-animal stabilized hyaluronic acid" (NASHA) is a widely used product in bio-revitalization injective procedures in esthetic medicine. The present research aimed to quantitatively evaluate the therapeutic effect of one of the more used bio-revitalization products on cultured dermal fibroblasts. RT-PCR was used for gene expression profiling of some proteins known to be relevant in skin homeostasis. METHODS Human dermal fibroblasts were seeded on a culture medium enriched with a product for dermal bio-revitalization, consisting of stabilized hyaluronic acid gel 20 mg/ml. After 24, 48, and 72 h of exposure, the cDNA was amplified by real-time PCR. Gene expression was quantified with the delta/delta calculation method. RESULTS In this study, the gene of metalloproteinase (MMP)-13 is strongly expressed after NASHA incubation. The MMP-2 encoding gene instead is less expressed, but both evidence the same temporal trend, being progressively up-regulated after 24 and 48 h, thereafter the expression decreases, whereas MMP-3 maintains the same up-regulation at 72 h. Hyaluronan synthase 1 and desmoplakin are progressively up-regulated and increase at 24, 48, and 72 h. Hyaluronidase 1 and neutrophil elastase genes are overexpressed, but at 72 h they both exhibit the same behavior as the other degradative enzymes MMP-13 and MMP-2. CONCLUSIONS Skin bio-revitalization by injecting the tested NASHA gel produces an enhancement in the expression of some genes involved in extracellular matrix degradation and organization. In this study, a time-dependent behavior, different for genes encoding degradative compared to synthesis proteins, was demonstrated.
