[PMID: 35726457 DOI: 10.1111/ijd.16307] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 04/10/2022] [Accepted: 05/25/2022] [Indexed: 12/01/2022]
Abstract
BACKGROUND F2-isoprostane is one of the members of biologically active prostaglandins. It is considered a reliable marker of oxidative stress. This study aimed at investigating and studying the hypothesis of the possible role of prostaglandin F2-alpha (PGF2α) in the pathogenesis of vitiligo and to know if there is a possibility of using it in therapy. METHODS This case-control study involved 30 patients with nonsegmental vitiligo and 30 healthy sex- and age-matched controls over a period of 7 months. Skin biopsies were taken from lesional and nonlesional vitiliginous skin of patients and from normal skin of controls for measurement of PGF2α in tissue by ELISA. RESULTS The tissue levels of PGF2α in vitiligo patients were significantly higher in both lesional and nonlesional skin than in healthy controls (P < 0.001). The tissue levels of PGF2α in lesional skin were significantly higher than in nonlesional skin (P < 0.001). CONCLUSION Based on the fact that PGF2α is a reliable biomarker of oxidative stress, in addition to our results that revealed higher tissue levels of PGF2α in vitiliginous skin than in healthy skin, we can conclude that PGF2α may be incriminated in the pathogenesis of vitiligo. This finding could help in the treatment of this disease by using anti-PGF2α drugs.

Oxyberberine, a novel HO-1 agonist, effectively ameliorates oxidative stress and inflammatory response in LPS/D-GalN induced acute liver injury mice via coactivating erythrocyte metabolism and Nrf2 signaling pathway. Food Chem Toxicol 2022; 166:113215. [PMID: 35691465 DOI: 10.1016/j.fct.2022.113215] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 06/02/2022] [Accepted: 06/05/2022] [Indexed: 01/22/2023]
Abstract
Oxyberberine (OBB), a main gut-mediated metabolite of Phellodendron chinense Cortex (PC), exhibits prominent protective property against acute liver injury (ALI). Heme oxygenase-1 (HO-1) is a vital molecule in attenuating acute and chronic liver injury for its prominent anti-oxidative injury and anti-inflammation properties. The present study was performed to investigate the hepatoprotective role of OBB through HO-1 signaling pathway in lipopolysaccharide/D-galactosamine (LPS/D-GalN) induced ALI. Our results indicated that PC treatment improved survival rate and its metabolite OBB evidently improved histopathological deteriorations and liver function. Additionally, OBB dramatically ameliorated hepatic oxidative stress and inflammation. Besides, OBB exerted remarkable HO-1 agonistic activity, even be comparable to hemin (a HO-1 inducer), as evidenced by increased HO-1 level, carbon monoxide and bilirubin activities, which are the markers of erythrocyte metabolism. Moreover, OBB modulated the parameters of inflammation and oxidative stress through HO-1 dependent pathway. Beyond this, OBB also notably suppressed the translocation of p65, enhanced antioxidation defense genes expressions, promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nuclear translocation of nuclear factor-erythroid-2-related factor 2 (Nrf2). In conclusion, OBB could be the principle active metabolite substance of PC and exert excellent hepatoprotective effects via inducing HO-1 through coactivation of erythrocyte metabolism and Nrf2/HO-1 pathway.

Abstract
BACKGROUND Skin, as a crucial external defense organ, is more vulnerable to oxidative stress (OS) insult, reactive oxygen species (ROS)-mediated OS in particular. OS results from a redox imbalance caused by various extrinsic stimuli and occurs once the oxidants production overwhelming the antioxidants capacity, through mediating in DNA damage, lipid peroxidation (LPO), protein oxidation and a serial of signaling pathways activation/inactivation, thereby offering favorable conditions for the occurrence and development of numerous diseases especially some dermatoses, e.g. psoriasis, vitiligo, skin photodamage, skin cancer, systemic sclerosis (SSc), chloasma, atopic dermatitis (AD), pemphigus, etc. Targeting OS molecular mechanism, a variety of anti-OS agents emerge, in which flavonoids, natural plant extracts, stand out. OBJECTIVES To discuss the possible mechanisms of OS mediating in dermatoses and summarize the properties of flavonoids as well as their applications in OS-related skin disorders. METHODS Published papers on flavonoids and OS-related skin diseases were collected and reviewed via database searching on PubMed, MEDLINE and Embase, etc. RESULTS It has been confirmed that flavonoids, belonging to polyphenols, are a class of plant secondary metabolites widely distributed in various plants and possess diverse bioactivities especially their potent antioxidant capacity. Moreover, flavonoids benefit to suppress OS via eliminating free radicals and mediating the corresponding signals, further excellently working in the prevention and management of OS-related skin diseases. CONCLUSION Flavonoids have the potential therapeutic effects on oxidative stress-related dermatoses. However, more studies on specific mechanism as well as the dosage of flavonoids are needed in future.

Abstract
Natural products have been used to protect the skin from harmful UV radiation for decades. Due to the ecotoxicological implications of synthetic sunscreen exposure in aquatic ecosystems, there is a greater need to explore alternative sources of UV filters. Recent research has focused on discovering novel UV absorbing photoprotective molecules from nature. In response to the excessive damage caused by UVB rays, plants induce the production of high concentrations of phytoprotective secondary metabolites and anti-oxidative enzymes. Despite promising UV absorbing and photoprotective properties, plant secondary metabolites have been underutilized in topical delivery due to low solubility and high instability. Numerous phytochemicals have been effectively nanosized, incorporated in formulations, and studied for their sustained effects in photoprotection. The present review outlines recent developments in nanosizing and delivering photoprotective crude plant extract and phytochemicals from a phytochemical perspective. We searched for articles using keywords: "UV damage," "skin photoprotection," "photodamage," and "nano delivery" in varied combinations. We identified and reviewed literature from 43 original research articles exploring nanosized phytochemicals and crude plant extracts with photoprotective activity. Nanosized phytochemicals retained higher amounts of bioactive compounds in the skin and acted as depots for their sustained release. Novel approaches in nanosizing considerably improved the photostability, efficacy, and water resistance of plant secondary metabolites. We further discuss the need for broad-spectrum sunscreen products, potential challenges, and future growth in this area.

Abstract
Skin cancer is considered the most prevalent cancer type globally, with a continuously increasing prevalence and mortality growth rate. Additionally, the high risk of recurrence makes skin cancer treatment among the most expensive of all cancers, with average costs estimated to double within 5 years. Although tumor excision is the most effective approach among the available strategies, surgical interventions could be disfiguring, requiring additional skin grafts for covering the defects. In this context, post-surgery management should involve the application of wound dressings for promoting skin regeneration and preventing tumor recurrence and microbial infections, which still represents a considerable clinical challenge. Therefore, this paper aims to provide an up-to-date overview regarding the current status of regenerative wound dressings for skin cancer therapy. Specifically, the recent discoveries in natural biocompounds as anti-cancer agents for skin cancer treatment and the most intensively studied biomaterials for bioactive wound dressing development will be described.

Abstract
Background: According to the side effects of the usual treatment of burns, in improving the patients’ prognosis, there is a need to introduce faster and more effective adjuvant therapies to treat wounds, thus to improve the prognosis of patients. The aim of this study was to investigate the effect of adjuvant treatment with oral silymarin on wound healing process caused by second degree-burns among the patients admitted to Valiasr Hospital of Arak. Methods: This randomized, double-blind clinical trial study was carried out on 80 patients with second-degree burns covering 20 to 30 percent of the body with flame. Patients were randomized into 2 groups with an equal number: The intervention group (treated daily with oral 140-mg silymarin) and control (under the administration of placebo). Patients were treated for 8 weeks and at the end of weeks 1, 2, 3 and 4 according to the degree of wound healing (grade 1, 2 and 3) were followed during 2016-2017. Results: Changes in degrees of burn wound healing in both the intervention and placebo groups during the 4 weeks of treatment, significantly improved grade 3 completely. Based on the results, the complete remission in all four follow-up stages was significantly higher in silymarin group than the placebo group: Week 1 (intervention: 9 (22.5%), control: 0 (0%), (p=0.011), week 2 (intervention group: 18 (45%), placebo: 7 (17.5%), (p=0.000), week 3 (intervention: 24 (60%), placebo: 11 ( 27.5%), (p=0.051); week 4 (intervention: 27 (67.5%), control: 19 (47.5%), (p=0.003). Conclusions: According to our results, the 4-week adjuvant treatment with oral silymarin resulted in the full and faster wound recovery in patients with second degree-burn. So, it is recommended to use adjuvant treatments to obtain effective results.
