Effects of Bentonite Clay on Lacerated Wound: A Single Case Study from Tamil Nadu, India.

To control infection and promote healing, bentonite, a montmorillonite clay, was used topically to treat lacerate wounds. This clay has been used historically for both beauty and burn treatment. This clay possesses anti-inflammatory, antibacterial, and antioxidant qualities. Through the stimulation of collagen production, cell proliferation, and angiogenesis, bentonite clay promotes the healing of lacerations. The production of anti-inflammatory mediators was suppressed when lacerated lesions were treated with bentonite clay. It also has a significant impact on lacerated wound infection management. Bentonite clay's effects on lacerations. In Kulasekharam, Tamil Nadu, India, at the Sree Ramakrishna Medical College of Naturopathy and Yogic Sciences and Hospital, a single case study was carried out. The female participant in this study is 19 years old. Verbal consent was gained following an explanation of the study's objectives. Our research suggests that bentonite clay is an effective treatment for lacerations. It is a natural remedy. This outcome demonstrated that the treatment has a major, non-complicative impact on the healing of lacerations. Future research with bigger sample sizes is advised in order to increase generality.

Facial acupuncture as a way to restore external and internal well-being

Facial acupuncture is non‑invasive and safe, and it can significantly improve skin elasticity by stimulating collagen production and enhancing blood circulation. This leads to reduction in wrinkles, improvement in muscle tone, and skin tightening. Acupuncture can help alleviate inflammatory skin conditions like acne or psoriasis by regulating hormonal function and the immune system. Additionally, it can bring mental health benefits by reducing stress and enhancing overall well‑being, potentially boosting self‑confidence and self‑acceptance. Ultimately, facial acupuncture represents a holistic approach to health and beauty, focusing not only on enhancing external appearance but also on balancing the internal energy of the body, which can have a positive impact on quality of life.

Cellular metabolism of substance P produces neurokinin-1 receptor peptide agonists with diminished cyclic AMP signaling.

Substance P (SP) is released from sensory nerves in the arteries and heart. It activates neurokinin-1 receptors (NK1Rs) causing vasodilation, immune modulation, and adverse cardiac remodeling. The hypothesis was tested: SP and SP metabolites activate different second messenger signaling pathways. Macrophages, endothelial cells, and fibroblasts metabolized SP to N- and C-terminal metabolites to varying extents. SP 5-11 was the most abundant metabolite followed by SP 1-4, SP 7-11, SP 6-11, SP 3-11, and SP 8-11. In NK1R-expressing human embryonic kidney 293 (HEK293) cells, SP and some C-terminal SP metabolites stimulate the NK1R, promoting the dissociation of several Gα proteins, including Gαs and Gαq from their βγ subunits. SP increases intracellular calcium concentrations ([Ca]i) and cyclic 3',5'-adenosine monophosphate (cAMP) accumulation with similar -log EC50 values of 8.5 ± 0.3 and 7.8 ± 0.1 M, respectively. N-terminal metabolism of SP by up to five amino acids and C-terminal deamidation of SP produce peptides that retain activity to increase [Ca]i but not to increase cAMP. C-terminal metabolism results in the loss of both activities. Thus, [Ca]i and cAMP signaling are differentially affected by SP metabolism. To assess the role of N-terminal metabolism, SP and SP 6-11 were compared with cAMP-mediated activities in NK1R-expressing 3T3 fibroblasts. SP inhibits nuclear factor κB (NF-κB) activity, cell proliferation, and wound healing and stimulates collagen production. SP 6-11 had little or no activity. Cyclooxygenase-2 (COX-2) expression is increased by SP but not by SP 6-11. Thus, metabolism may select the cellular response to SP by inhibiting or redirecting the second messenger signaling pathway activated by the NK1R.NEW & NOTEWORTHY Endothelial cells, macrophages, and fibroblasts metabolize substance P (SP) to N- and C-terminal metabolites with SP 5-11 as the most abundant metabolite. SP activates neurokinin-1 receptors to increase intracellular calcium and cyclic AMP. In contrast, SP metabolites of N-terminal metabolism and C-terminal deamidation retain the ability to increase calcium but lose the ability to increase cyclic AMP. These new insights indicate that the metabolism of SP directs cellular functions by regulating specific signaling pathways.

Clinical efficacy of intradermal type I collagen injections in treating skin photoaging in patients from high-altitude areas

BACKGROUND Photoaging, a result of chronic sun exposure, leads to skin damage and pigmentation changes. Traditional treatments may have limitations in high-altitude areas like Yunnan Province. Intradermal Col Ι injections stimulate collagen production, potentially improving skin quality. This study aims to assess the efficacy and safety of this treatment for photoaging. AIM To evaluate the efficacy and safety of intradermal type Ι collagen (Col Ι) injection for treating photoaging. METHODS This prospective, self-controlled study investigated the impact of intradermal injections of Col Ι on skin photodamage in 20 patients from the Yunnan Province. Total six treatment sessions were conducted every 4 wk ± 3 d. Before and after each treatment, facial skin characteristics were quantified using a VISIA skin detector. Skin thickness data were assessed using the ultrasound probes of the Dermalab skin detector. The Face-Q scale was used for subjective evaluation of the treatment effect by the patients. RESULTS The skin thickness of the right cheek consistently increased after each treatment session compared with baseline. The skin thickness of the left cheek significantly increased after the third through sixth treatment sessions compared with baseline. The skin thickness of the right zygomatic region increased after the second to sixth treatment sessions, whereas that of the left zygomatic region showed a significant increase after the fourth through sixth treatment sessions. The skin thickness of both temporal regions significantly increased after the fifth and sixth treatment sessions compared with baseline (P < 0.05). These findings were also supported by skin ultrasound images. The feature count for the red areas and wrinkle feature count decreased following the treatment (P < 0.05). VISIA assessments also revealed a decrease in the red areas after treatment. The Face-Q-Satisfaction with Facial Appearance Overall and Face-Q-Satisfaction with Skin scores significantly increased after each treatment session. The overall appearance of the patients improved after treatment. CONCLUSION Intradermal Col Ι injection improves photoaging, with higher patient satisfaction and fewer adverse reactions, and could be an effective treatment method for populations residing in high-altitude areas.

Evaluation of pain level during microfocused ultrasound treatment in the lower eyelid and lateral eye region: an observational study

Microfocused ultrasound is a non-invasive technology widely used for its ability to stimulate collagen production, generate fat lipolysis and provide lifting. Despite its benefits, many patients avoid the procedure due to the associated pain and discomfort. The aim of this study was to quantitatively evaluate the pain perceived during the application of HIPRO microfocused ultrasound to the lower eyelids and sides of the eyes, using the numerical pain scale (NRS). The sample consisted of 10 individuals aged between 30 and 50. The methodology included the application of HIPRO at a frequency of 10Hz and a depth of 1.5mm, with 900 shots per treated area. Pain was measured after 450 and 900 shots. The results showed that the majority of patients rated their pain as mild or non-existent, with an average score of 1.175 out of 10 on the NRS. The variability in pain perception reinforces the importance of personalized approaches. Compared to other devices, HIPRO proved to be an effective and relatively comfortable alternative, especially for pain-sensitive patients. It is concluded that HIPRO microfocused ultrasound is a safe and effective option for facial rejuvenation, with a manageable discomfort profile and good clinical results.

Fractional Ablative Carbon Dioxide Laser versus Fractional Non-Ablative 1410 nm Diode Laser in the Treatment of Acne Scars: A Clinical and Immunohistochemical Study

Background: Effectively managing acne scars while minimizing consequences is still a challenging task. The primary determinant in selecting and continuing therapy for a specific device is stimulating collagen production and dermal remodeling with the fewest possible complications. Objective: To evaluate the clinical and immunohistochemical results of ablative fractional carbon dioxide (FCO2) laser versus fractional non-ablative diode laser for treating facial acne scars. Methods and Materials: Thirty patients with atrophic acne scars were included in a split-face comparative study. Right and left facial sides received three sessions of FCO2 and diode laser, respectively, at one-month intervals. One month after the third session, patients were evaluated using photographs, the Goodman and Baron qualitative and quantitative global scarring grading system, the investigator’s global assessment, and patient satisfaction. A sample was collected from the area that had been treated, and the tissue was examined using hematoxylin and eosin (H–E) staining and immunohistochemistry staining for collagen I. Results: Goodman and Baron global scores showed a statistically significant difference compared to baseline on both sides of the face. However, there was no statistically significant difference between the two treatment modalities. Biopsy specimens showed an increased deposition of collagen I by both laser devices, which was validated and described by immunohistochemistry staining. Conclusion: Both FCO2 and fractional non-ablative diode lasers proved their efficacy in treating different types of acne scars. For patients who are interested in no downtime and no complications, fractional non-ablative diode laser is recommended as an efficient alternative modality.

Effect of Helichrysum italicum in Promoting Collagen Deposition and Skin Regeneration in a New Dynamic Model of Skin Wound Healing.

Natural products have many healing effects on the skin with minimal or no adverse effects. In this study, we analyzed the regenerative properties of a waste product (hydrolate) derived from Helichrysum italicum (HH) on scratch-tested skin cell populations seeded on a fluidic culture system. Helichrysum italicum has always been recognized in the traditional medicine of Mediterranean countries for its wide pharmacological activities. We recreated skin physiology with a bioreactor that mimics skin stem cell (SSCs) and fibroblast (HFF1) communication as in vivo skin layers. Dynamic culture models represent an essential instrument for recreating and preserving the complex multicellular organization and interactions of the cellular microenvironment. Both cell types were exposed to two different concentrations of HH after the scratch assay and were compared to untreated control cells. Collagen is the constituent of many wound care products that act directly on the damaged wound environment. We analyzed the role played by HH in stimulating collagen production during tissue repair, both in static and dynamic culture conditions, by a confocal microscopic analysis. In addition, we performed a gene expression analysis that revealed the activation of a molecular program of stemness in treated skin stem cells. Altogether, our results indicate a future translational application of this natural extract to support skin regeneration and define a new protocol to recreate a dynamic process of healing.

Using an intense pulsed light (IPL) module for the treatment of pigmented lesions.

Pigmented lesions are largely benign and may lead to extreme distress. Various light and lasers may be used to treat pigmentation, often Q-switched lasers are considered the method of choice, while intense pulsed light (IPL) devices may offer a less invasive treatment with a shorter downtime. The purpose of this study is to evaluate the safety and efficacy of a narrowband IPL module for the treatment of pigmented lesions. A retrospective study of 20 patients with pigmented lesions underwent treatment with an IPL module. Treatment was assessed by blinded evaluation of clinical photographs using a GAIS scale of 0-10, as well as through patient satisfaction ratings on a scale of 0-10. Throughout the treatment, pain levels and adverse events were monitored. The mean GAIS score was 7.55 ± 1.15 (mean ± SD), and the mean patient satisfaction score was 7.3 ± 1.26 (mean ± SD). There was a strong positive correlation between GAIS and patient satisfaction scores (r = 0.83), and no significant difference between them (p-value = 0.516). The number of treatments did not significantly affect GAIS and patient satisfaction scores (p-values 0.364 and 0.126). Additional positive unexpected outcomes were improved skin firmness and reduced wrinkles. The results of the study indicate that the IPL module is both safe and effective in treating pigmented lesions and may have the potential to stimulate collagen production.

Effect of poly-L-lactic acid and polydioxanone biostimulators on type I and III collagen biosynthesis.

Safe, effective, and biocompatible minimally invasive procedures with the potential to stimulate collagen production have been made to recover dermal thickness and skin quality. The main of this animal model experiment was to observe the effect of poly-L-lactic acid (PLLA) and polydioxanone (PDO) biostimulators in collagen I and III after hypodermal injection. Sixteen adult female rats (Wistar) were randomized into four groups and had dorsal treatment with: G1: hypodermic subcision (HS) only; G2: HS and PLLA hypodermic injection (HI), G3: HS and PDO HI; G4: Control, with no treatment. In histochemical, it was observed hypodermal and dermal tissue in more organized thickness in G3 and in G4 when compared to G1 and G2. There was few difference in G1 compared to G4. The tissue of G2 showed irregularities in the arrangement of collagen fibers, less defined structure and lower distribution of type I collagen compared to the other groups. There is a greater tendency for the proportions of type III collagen among tissues treated with both biostimulators (G2 and G3). PLLA and PDO had relatively similar percentages of collagen when compared to G4. The amount of type I collagen was higher in tissues treated with subcision, while type III collagen was higher in tissues treated with both biostimulators. G3 showed better performance in collagen production, although small, when compared with G2.

A new nonsurgical combination approach for skin tightening and remodeling; Endoskin-A comparative study.

This article introduces a novel nonsurgical skin tightening and remodeling approach termed Endoskin, which combines internal laser therapy (1470 nm Diode laser) with injectable poly-L-lactic acid (PLLA). The internal laser targets the superficial fat layer, stimulating collagen production and cellular rejuvenation, leading to gradual skin tightening and improved elasticity. Simultaneously, PLLA promotes collagen synthesis, strengthening the skin's foundation and restoring volume. This comprehensive exploration delves into Endoskin's mechanisms, clinical applications, and its differentiation from traditional methods. The study encompassed 234 participants, categorized into two groups: Group A received internal laser treatment and Group B received the combined Endoskin treatment. Patient satisfaction, assessed using a Likert scale unveiled significantly higher levels in Group B. Dermatologists, blinded to treatment details, also expressed greater satisfaction with the combination treatment outcomes. The ensuing discussion emphasizes the synergistic effects of internal laser therapy and PLLA, presenting a multifaceted approach to skin rejuvenation. The study results underscore Endoskin's efficacy, safety, and its potential as a nonsurgical option for skin tightening and remodeling. The gradual and harmonious transformation aligns with natural aging, positioning Endoskin as an appealing choice for those seeking subtle yet impactful changes. In conclusion, Endoskin demonstrates notable efficacy, reliability, and safety in achieving skin rejuvenation. Although further research is warranted to assess its long-term effects, the current findings position Endoskin as a promising option with a significantly higher level of overall patient and dermatologist satisfaction compared to internal laser treatment alone.

Advanced Facial Rejuvenation: Synergistic Effects of Lower Blepharoplasty and Ultrasound Guided Mid-Face Lift Using Polydioxanone (PDO) Threads

BackgroundTraditional facial aging surgeries have risks and extended recovery times, leading to a demand for minimally invasive alternatives. PDO (polydioxanone) threads, which are absorbable sutures that stimulate collagen production and tissue contraction, offer improved aesthetic outcomes. This paper evaluates the combined use of PDO thread mid-cheek lift and lower blepharoplasty for facial rejuvenation.MethodsThis retrospective study compared outcomes in patients undergoing lower blepharoplasty combined with a mid-face lift using PDO threads versus those undergoing only lower blepharoplasty. Focused on individuals with baggy lower eyelids and pronounced nasolabial folds, outcome measures included the Modified Fitzpatrick wrinkle scale, Allergan® midface volume deficit scale, Width of inter zygomatic distance, Patient and Observer Scar Assessment Scale, and patient satisfaction questionnaires, assessed at baseline, 3 months, and 1 year postoperatively.ResultsThe combined procedure demonstrated superior aesthetic outcomes and higher patient satisfaction compared to lower blepharoplasty alone. Improvements were more significant in wrinkle reduction, midface volume, and inter-zygomatic distance in the combined procedure group. Although the combined procedure had a longer mean operation time, scar assessment scores were similar between both groups, with no complications reported.ConclusionThe combination of lower blepharoplasty and mid-face lift using PDO threads is a comprehensive and effective approach for facial rejuvenation. It significantly enhances wrinkle reduction, mid-face lifting, and patient satisfaction. Ultrasound-guided thread lifting, a method of assessing and performing mid-face lifting, proves to be safe and efficient. This approach holds promise as a future option in cosmetic anti-aging surgery, presenting a minimally invasive alternative with natural-looking results and reduced downtime.Level of Evidence IIThis journal requires that authors assign a level of evidence to each article.

Liposome Encapsulation of the Palmitoyl-KTTKS Peptide: Structural and Functional Characterization.

In this study, the amphiphilic N-palmitoyl-KTTKS peptide was integrated in the bilayer of egg-derived phosphatidylcholine (PC) vesicles using two different preparation methods, namely thin-film evaporation (TLE) and reverse-phase evaporation (REV). Both the REV and TLE methods allowed for the formation of homogeneous liposome dispersions (PdI < 0.20) with mean hydrodynamic diameters of <100 nm and <200 nm, respectively, a net negative surface charge and a percentage of structured phospholipids higher than 90%. The inclusion of the amphiphilic N-palmitoyl-KTTKS peptide within phospholipid-based vesicles could improve peptide stability and skin delivery. Therefore, the obtained liposomes were evaluated via experiments assessing the synthesis of collagen and the ECM in 3T3-NIH fibroblasts. The obtained results showed that, when delivered with PC liposomes, pal-KTTKS stimulated collagen production more than free pentapeptide and 1 mM ascorbic acid, used as a positive control.

Subjective evaluation of monopolar radiofrequency treatment by patients in aesthetic rejuvenation.

To assess the subjective experiences of patients following monopolar radiofrequency (RF) treatment for facial rejuvenation and anti-aging purposes. A study involving 50 female patients (aged 30-70years, Fitzpatrick skin type III and IV) who received a single session of RF treatment. Exclusion criteria comprised active infections, skin diseases, pregnancy, or history of recent anti-aging treatments. Thirty-four patients completed a 10-question questionnaire after 3months of treatment. Among the respondents, 82% expressed satisfaction with the RF treatment, reporting significant improvements primarily in the mid and lower face, and eyelids. Mainly, patients noted improvements in skin laxity (52.9%), skin texture (17.6%), and skin tone (11.7%). Notably, 73.5% noticed changes within 1-2months post-treatment, with the peak effect observed at 1-2months. Mild complications (swelling and erythema) were reported, usually resolving within a week. The mean pain score was 1.94 (±0.66), indicating mild to moderate discomfort. Monopolar RF devices, apply high-frequency electric currents generating heat, stimulating collagen production for skin tightening. This study's unique focus on detailed subjective patient experiences provides insights valuable in clinical settings, aiding clinicians in managing patient expectations and achieving optimal results. The satisfaction rates align with previous findings, emphasizing RF treatment's efficacy in addressing facial laxity, especially in the mid and lower face. Positive feedback extended beyond skin tightening, encompassing skin texture and tone improvements. While the study's observation period was 3months post-treatment, longer-term studies are warranted for comprehensive assessments. The study underscores the efficacy of monopolar RF device, as a non-invasive and effective anti-aging treatment. The findings contribute to diversifying the RF market, potentially aiding clinicians in optimizing patient care. Considering the growing complexity of patient demands and treatment responses, this study serves as a valuable reference for clinicians engaging in RF treatments.

Cosmetic application of the stem-bark extract of Bertholletia excelsa H.B.K.

The Amazon has a rich biodiversity where many different plant species can be found. This diversity is an important source of bioactive substances, mainly due to the different structural components of their phytometabolites. Research for natural products is a strategy for the development of new agents in therapeutic applications, especially cosmetic applications, that have better pharmacological potential. Within this perspective, the objective of the study was to investigate the cosmetic application (anti-aging potential) of the stem-bark extract of Bertholletia excelsa H.B.K - (SBEBE), popularly known as the Brazil nut tree, here called SBEBE, a noble plant species of the Amazon that is rich in selenium. Enzymatic, glycation, proliferation, cell-healing, collagen quantification, toxicity and genotoxicity assays were used. Among the enzymes involved in the extracellular matrix of the skin, SBEBE was able to inhibit only elastase (62.67 ± 3.75) when compared to the standard sivelestat (89.04 ± 0.53), and the extract was also able to inhibit both the oxidative and the non-oxidative pathway. When cell toxicity in fibroblasts (MRC-5) and keratinocytes (HACAT) was evaluated, SBEBE did not present toxicity in 24 h of incubation. After this period, the extract showed average cytotoxicity in 48 and 72 h, but not enough to reach the concentration of 50% of MRC-5 fibroblasts. In the trypan blue assay, the extract promoted fibroblast proliferation in 24, 48 and 72 h of incubation, which was evaluated through exponential cell growth, with emphasis mainly on the lowest concentration with results higher than the standard. When the cell healing capacity was evaluated, in 48 h of exposure to fibroblast, SBEBE was able to induce a cell carpet (cell film) in the cell monolayer scratch assay. SBEBE stimulated collagen production at all concentrations tested. In the alkaline comet assay, at the lowest concentration, the extract did not induce DNA damage when compared to the reference drug doxorubicin. This study proved that SBEBE extract can be considered an ally in the treatment of skin anti-ageing as a possible biotechnological, phytocosmetic product.

Physicochemical Characteristics, Fatty Acid Profile, and In Vitro Antioxidant Activity Evaluation of Sacha Inchi Seed Oil from Indonesia

Free radicals can cause damage to the structure of the dermis layer, which makes skin lose its elasticity and leads to the formation of wrinkles. A strategy to prevent this problem is by using antioxidants. A plant that has been reported to contain good antioxidant activity is sacha inchi seed (Plukenetia volubilis L.); apart from that, its oil has quite a high omega-3 content and potentially can act as an anti-aging agent stimulating the skin-cell-regeneration process, maintaining skin moisture and elasticity and stimulating collagen production. This research aims to analyze the physicochemical characteristics and determine the fatty acid profile, the levels of vitamins A, D, and E, and the antioxidant activity of sacha inchi seed oil. This research was conducted through eight main stages: sacha inchi seed extraction, quality parameters checking, phytochemical screening, determining fatty acid profiles, vitamin analysis, antioxidant activity tests, microbiological contamination tests, and heavy-metal contamination tests. In this study, quality inspection results were obtained: organoleptic form (liquid), color (yellow), odor (typical), relative density value (0.91 g/cm3), acid number (0.38 ± 0.02 mg/g), peroxide value (11.01 mEq/Kg), iodine value (179.32 g/100 g), and refractive index (1.479). The phytochemical screening results of sacha inchi seed oil were positive for containing flavonoids, triterpenoids, and steroids. The results of the fatty acid profile were omega-3 (48.5%), omega-6 (34.8%), and omega-9 (7.7%). The results of the vitamin contents analysis were vitamin A (123.42 mg/100 g), vitamin D (899.46 mg/100 g), and vitamin E (145.06 mg/100 g). The antioxidant activity test showed an IC50 value of 8.859 ppm (very strong), and the microbial and heavy-metal contamination tests were negative.

Assessing the Anti-Aging and Wound Healing Capabilities of Etlingera elatior Inflorescence Extract: A Comparison of Three Inflorescence Color Varieties.

Torch ginger, Etlingera elatior, is a Zingiberaceae plant with various red, pink, and white inflorescence. The wound healing potential and anti-aging effects of freeze-dried torch ginger inflorescence extracts (FTIEs) from three varieties were compared. The red FTIE had the highest content of phenolic, flavonoid, caffeoylquinic acid, and chlorogenic acid, followed by the white and pink FTIE. Consistent with the chemical constituents, the red FTIE demonstrated the greatest capacities for free radical scavenging, anti-tyrosinase, and anti-collagenase activity, followed by the white and pink FTIE. In cell-based studies, FTIEs displayed cytotoxicity to B16F10 melanoma cells, with the red FTIE showing the greatest activity (LC50 of 115.5 μg/mL). In contrast, the pink and the white FTIEs had less cytotoxicity impact. Nonetheless, at 1000 μg/mL, all three FTIE variants were safe on L929 fibroblasts or RAW 264.7 monocyte cells. White FTIE (500 μg/mL) exhibited the highest activity in stimulating collagen production and the greatest impact on cell migration, whereas the pink and red FTIE had a lesser effect. All FTIEs slightly suppressed the pro-inflammatory cytokines produced by lipopolysaccharide-stimulated monocytes, with no significant variation between FTIE variants. In conclusion, all FTIEs revealed promising potential for anti-aging cosmeceuticals and wound care products at specific concentrations.

EXPLORING THE MEDICINAL MARVEL: THE POTENTIAL OFYARSAGUMBA AS REGENERATIVE MEDICINE AND IN WOUND HEALING

Yarsagumba(Cordyceps mushroom) a valued herbal medicine, is a fungus that grows on ghost moth larvae. It belongs to the Ophiocordycipitaceae family and has been used in traditional Chinese medicine for centuries. It has various applications in the pharmaceutical and health industries. In Nepal, Yarsagumba has been recognized for thousands of years and is considered one of the most promising medicinal mushrooms. Scientists have been studying its unique life cycle and medical uses for the past 30 years.However, once correctly identified, these enigmatic organisms hold great promise in the prevention and treatment of numerous ailments such as cancer,woundhealing, antidiabetic, alleviating fatigue, respiratoryproblems, and erectile dysfunction in men.Cordyceps fungi possess significant phytochemicals, namely cordycepin and adenosine, which function by suppressing the adenosine A2 receptor and consequently inhibiting various neuroinflammatory markers such as NF-κB, NLRP3 inflammasome, IL-1β, iNOS, COX-2, TNF-α, and HMGB1. Yarsagumbas wound healing properties are multifaceted, with its anti-inflammatory and antioxidant compounds reducing inflammation and preventing tissue damage. Its immunomodulatory effects enhance the bodys immune response and inhibit the growth of harmful microorganisms, reducing the risk of infection. Yarsagumbas regenerative capabilities stimulate collagen production and promote angiogenesis, resulting in improved wound healing outcomes and minimized scarring. This review examines how Yarsagumbas bioactive compounds can enhance wound healing, reduce scarring, and improve tissue repair. It also explores the plants regenerative properties, such as its ability to stimulate stem cell growth and differentiation. Our findings indicate that the activation of adenosine receptors by adenosine and cordycepin effectively triggers the Wnt/β-catenin signaling, which can potentially facilitate tissue remodeling and serve as a therapeutic approach for skin wound treatment.

Beta-Sitosterol Alters Collagen Distribution in Prostate Fibroblasts

Herbal supplements containing several types of plant sterols, vitamins, and minerals, are marketed for prostate health. In the majority of these supplements, the most abundant plant sterol is saw palmetto extract or its’ principal component, beta-sitosterol. In terms of prostate health, previous work almost exclusively focused on the effects of beta-sitosterol on prostatic epithelium, with little attention paid to the effects on prostatic stroma. This omission is a concern, as the abnormal accumulation of collagen, or fibrosis, of the prostatic stroma has been identified as a factor contributing to lower urinary tract symptoms and dysfunction in aging men. To address whether beta-sitosterol may be promoting prostatic fibrosis, immortalized and primary prostate stromal fibroblasts were subjected to immunoblotting, immunofluorescence, qRT-PCR, ELISA, and image quantitation and analysis techniques to elucidate the effects of beta-sitosterol on cell viability and collagen expression and cellular localization. The results of these studies show that beta-sitosterol is nontoxic to prostatic fibroblasts and does not stimulate collagen production by these cells. However, beta-sitosterol alters collagen distribution and sequesters collagen within prostatic fibroblasts, likely in an age-dependent manner. This is a significant finding as prostate health supplements are used predominantly by middle aged and older men who may, then, be affected disproportionately by these effects.

Chlamydial YAP activation in host endocervical epithelial cells mediates pro-fibrotic paracrine stimulation of fibroblasts.

Chronic or repeated infection of the female upper genital tract by C. trachomatis can lead to severe fibrotic sequelae, including tubal factor infertility and ectopic pregnancy. However, the molecular mechanisms underlying this effect are unclear. In this report, we define a transcriptional program specific to C. trachomatis infection of the upper genital tract, identifying tissue-specific induction of host YAP-a pro-fibrotic transcriptional cofactor-as a potential driver of infection-mediated fibrotic gene expression. Furthermore, we show that infected endocervical epithelial cells stimulate collagen production by fibroblasts and implicate chlamydial induction of YAP in this effect. Our results define a mechanism by which infection mediates tissue-level fibrotic pathology via paracrine signaling and identify YAP as a potential therapeutic target for the prevention of Chlamydia-associated scarring of the female genital tract.
