[PMID: 37891908 PMCID: PMC10603872 DOI: 10.3390/antiox12101829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/30/2023] [Accepted: 10/03/2023] [Indexed: 10/29/2023] Open
Abstract
An industry listed as one of the largest globally is the cosmetic industry. In recent years, this industry has shown growing interest in the application of natural ingredients providing advanced properties to cosmetic creams such as moisturizing, antioxidant, sun-protecting and antimicrobial effects. In this context, the present study concerns the production of cosmetic emulsions containing hippophae oil obtained via the methods of extraction, hydro-distillation and maceration using sunflower oil as the carrier oil. Firstly, an IR-ATR analysis was performed showing that the oils prepared were close to those commercially obtained. Then, the stability of the emulsions was tested over a time period of four months through measuring their pH and viscosity values with positive outcomes, and their antioxidant ability was also measured using the DPPH method. The latter one showed that hippophae oil greatly improves the antioxidant capacity. Moreover, based on the fact that sea buckthorn contains carotenoids, the SPF value of the emulsions was determined. The results showed that the addition of hippophae oil to the emulsions gave higher absorption in UV-Vis, thus higher SPF values. Py-GC/MS analysis was used to identify decomposition compounds in the produced oils. Among those, valuable compounds such as Ω-6, Ω-7 and Ω-9 fatty acids and many aldehydes were found by the decomposition of the oils.

Protective Effect of Amaranthus cruentus L. Seed Oil on UVA-Radiation-Induced Apoptosis in Human Skin Fibroblasts. Int J Mol Sci 2023; 24:10795. [PMID: 37445970 DOI: 10.3390/ijms241310795] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 06/16/2023] [Accepted: 06/20/2023] [Indexed: 07/15/2023] Open
Abstract
Since the exposure of fibroblasts to prolonged UVA radiation induces oxidative stress and apoptosis, there is a need for effective skin protection compounds with cytoprotective and antioxidant properties. One of their sources is Amaranthus cruentus L. seed oil (AmO), which is rich in unsaturated fatty acids, squalene, vitamin E derivatives and phytosterols. The aim of this study was to evaluate whether AmO evokes a protective effect on the apoptosis induced by UVA radiation in human skin fibroblasts. UVA radiation at an applied dose of 10 J/cm2 caused a significant reduction in the survival of human skin fibroblasts and directed them into the apoptosis pathway. Increased expression of p53, caspase-3, caspase-9 and PARP proteins in UVA-treated fibroblasts suggests the intrinsic mechanism of apoptosis. Application of the oil at 0.1% and 0.15% concentrations to UVA-treated cells decreased the expression of these proteins, which was accompanied by increased cell survival. Similarly, the UVA-dependent decrease in the expression of p-Akt and mTOR proteins was restored under the effect of the studied oil. The molecular mechanism of this phenomenon was related to the stimulation of antioxidant processes through the activation of Nrf2. This suggests that AmO stimulated the antioxidant system in fibroblasts, preventing the effects of UVA-induced oxidative stress, which may lead to pharmaceutical and cosmetological applications as a sun-protective substance.

Determination of Chemical Composition and Investigation of Biological Activities of Ocimum basilicum L. Molecules 2023; 28:614. [PMID: 36677672 PMCID: PMC9866482 DOI: 10.3390/molecules28020614] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/08/2022] [Accepted: 10/12/2022] [Indexed: 01/11/2023] Open
Abstract
This study aimed to determine the chemical composition of the essential oils (EOs) of Ocimum basilicum L., as well as to evaluate the antibacterial, antidiabetic, dermatoprotective, and anti-inflammatory properties, and the EOs and aqueous extracts of O. basilicum. The antibacterial activity was evaluated against bacterial strains, Gram-positive and Gram-negative, using the well diffusion and microdilution methods, whereas the antidiabetic activity was assessed in vitro using two enzymes involved in carbohydrate digestion, α-amylase and α-glucosidase. On the other hand, the dermatoprotective and anti-inflammatory activities were studied by testing tyrosinase and lipoxygenase inhibition activity, respectively. The results showed that the chemical composition of O. basilicum EO (OBEO) is dominated by methyl chavicol (86%) and trans-anethol (8%). OBEO exhibited significant antibacterial effects against Gram-negative and Gram-positive strains, demonstrated by considerable diameters of the inhibition zones and lower MIC and MBC values. In addition, OBEO exhibited significant inhibition of α-amylase (IC50 = 50.51 ± 0.32 μg/mL) and α-glucosidase (IC50 = 39.84 ± 1.2 μg/mL). Concerning the anti-inflammatory activity, OBEO significantly inhibited lipoxygenase activity (IC50 = 18.28 ± 0.03 μg/mL) compared to the aqueous extract (IC50 = 24.8 ± 0.01 μg/mL). Moreover, tyrosinase was considerably inhibited by OBEO (IC50 = 68.58 ± 0.03 μg/mL) compared to the aqueous extract (IC50 = 118.37 ± 0.05 μg/mL). The toxicological investigations revealed the safety of O. basilicum in acute and chronic toxicity. The finding of in silico analysis showed that methyl chavicol and trans-anethole (main compounds of OBEO) validate the pharmacokinetics of these compounds and decipher some antibacterial targets.

Skincare in Rosacea from the Cosmetologist's Perspective: A Narrative Review. J Clin Med 2022; 12:jcm12010115. [PMID: 36614915 PMCID: PMC9821000 DOI: 10.3390/jcm12010115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2022] [Revised: 12/17/2022] [Accepted: 12/20/2022] [Indexed: 12/28/2022] Open
Abstract
Rosacea is a common skin disease that affects about 5% of the general population. Its symptoms include telangiectasia, persistent erythema, burning/stinging sensation, dry skin sensation, and pruritus. It is characterized by a chronic course with frequent exacerbation. It often coexists with anxiety and depression, reducing the quality of life of affected patients. The etiopathogenesis of rosacea is complex and not fully elucidated; hence, there is no causative effective treatment. In this review, we highlight the role of a cosmetologist in the treatment of rosacea and the maintenance of remission. As part of medical treatment, patients are advised to introduce lifestyle changes and use proper skin care; a cosmetologist can help educate patients affected with rosacea, create effective home care programs for skin care, and support them with treatments in beauty salons. Proper skin care is essential, including the use of dermocosmetics, cleansing of the skin, and frequent visits to beauty salons for tailored apparatus procedures. A cosmetologist is more accessible to patients and can help implement healthy daily habits, including skin care and eating habits, as well as support and mediate good communication between the patient and the patient's treating physician, thereby improving compliance and ensuring long-term satisfactory outcomes.

Abstract
Nanomaterials (NM) arouse interest in various fields of science and industry due to their composition-tunable properties and the ease of modification. They appear currently as components of many consumer products such as sunscreen, dressings, sports clothes, surface-cleaning agents, computer devices, paints, as well as pharmaceutical and cosmetics formulations. The use of NPs in products for topical applications improves the permeation/penetration of the bioactive compounds into deeper layers of the skin, providing a depot effect with sustained drug release and specific cellular and subcellular targeting. Nanocarriers provide advances in dermatology and systemic treatments. Examples are a non-invasive method of vaccination, advanced diagnostic techniques, and transdermal drug delivery. The mechanism of action of NPs, efficiency of skin penetration, and potential threat to human health are still open and not fully explained. This review gives a brief outline of the latest nanotechnology achievements in products used in topical applications to prevent and treat skin diseases. We highlighted aspects such as the penetration of NPs through the skin (influence of physical-chemical properties of NPs, the experimental models for skin penetration, methods applied to improve the penetration of NPs through the skin, and methods applied to investigate the skin penetration by NPs). The review summarizes various therapies using NPs to diagnose and treat skin diseases (melanoma, acne, alopecia, vitiligo, psoriasis) and anti-aging and UV-protectant nano-cosmetics.

Abstract
Acne and skin lesions that appear in its course deteriorate the quality of life of patients, cause depression and the emergence of suicidal thoughts. Cosmetic treatments can have a positive effect on improving skin condition by cleaning up skin eruptions, thus improving the well-being of affected people. Hydrogen purification is a treatment that uses alkaline water generated by a device, which reduces sebum from the surface of the epidermis. This is a novel treatment that has recently been introduced to beauty salons. On the other hand, cosmetic acids have been used for many years for treating people with acne vulgaris and give spectacular results in terms of improving the skin condition. In this study, skin condition was evaluated with a Derma Unit SSC 3 device. The Global Acne Grading System (GAGS) was used to check acne severity. Twenty-four women aged 19-21 years (M = 20.13, SD = 0.80) diagnosed with mild acne vulgaris and a high sebum level participated in the study. Group A underwent a hydrogen purification treatment using an H2jet manipulator, which ejected alkaline water from the manipulator under pressure. Group B underwent a hydrogen purification treatment with the use of a phytic, pyruvic, lactic and ferulic acids at 40% mixture (pH 1.4). A series of four treatments was performed at 14-day intervals in both groups. Skin parameters were measured before and 30 days after the series of treatment. Very good results were obtained in both groups. The skin eruptions in patients were reduced and we also observed lower amounts of sebum on the surface of the epidermis, and an improvement in skin hydration. However, in group B, the results were better than in group A. The study showed that the synergy of the treatments produced much better effects than those obtained by completing the hydrogen purification treatment alone.

Abstract
In the last decade, algae applications have generated considerable interest among research organizations and industrial sectors. Bioactive compounds, such as carotenoids, and Mycosporine-like amino acids (MAAs) derived from microalgae may play a vital role in the bio and non-bio sectors. Currently, commercial sunscreens contain chemicals such as oxybenzone and octinoxate, which have harmful effects on the environment and human health; while microalgae-based sunscreens emerge as an eco-friendly alternative to provide photo protector agents against solar radiation. Algae-based exploration ranges from staple foods to pharmaceuticals, cosmetics, and biomedical applications. This review aims to identify the effects of UV and UV-vis irradiation on the production of microalgae bioactive compounds through the assistance of different techniques and extraction methods for biomass characterization. The efficiency and results focus on the production of a blocking agent that does not damage the aquifer, being beneficial for health and possible biomedical applications.

Abstract
Aims Endoscopic thyroidectomy (ET) using the breast approach and conventional open thyroidectomy (OT) are effective approaches to treating thyroid tumors. This study evaluates the effectiveness of ET and OT regarding safety, cosmetic effects, and feasibility. Subjects and Methods Four hundred and fifty-six patients who underwent thyroidectomy in our department from January 2019 to August 2020 were included in this study. Based on the intraoperative rapid pathology, all patients with papillary thyroid carcinoma underwent unilateral thyroid lobectomy and central neck lymph node dissection. Whereas all benign patients underwent unilateral thyroid lobectomy. Differences in various factors such as clinical characteristics, operation time, postoperative drainage volume, parathyroid hormone (PTH) levels, calcium (Ca) levels, total number of central lymph nodes resected, the number of metastatic central lymph nodes resected, hospital duration, hospitalization costs, and cosmetic effects were compared in each group. Results Baseline characteristics among the four groups were similar, except for patient age and tumor size. Patients in the malignant ET group were younger than those in the malignant OT group with smaller tumors (P < 0.05). There were no significant differences between the OT and ET groups in postoperative Ca levels, PTH levels, the total number of lymph nodes resected, and the number of metastatic central lymph nodes resected. Conclusions Compared with conventional OT, ET is a feasible, practical, and safe procedure with excellent cosmetic benefits.

Abstract
BACKGROUND The lower limbs are an essential element of the structure of our body, bearing the weight and responsible for the correct motor skills. Defects in the functioning of the lower limbs and nails or foot skin can significantly affect the quality of life and limit full mobility. Due to the multitude of causes of podiatry changes, we consider their prevention and treatment interdisciplinary. AIMS This study aimed to examine the patient's awareness of selected podiatry units' prevention and treatment methods. PATIENTS/METHODS The study was an anonymous questionnaire consisting of 23 questions. The survey was carried out from November 4, 2020, to March 3, 2021. 516 questionnaires were collected. RESULTS The results indicate that pain in the area of the feet is common. It was shown that patients do not have enough awareness and knowledge about proper foot care, yet the vast majority, mainly using Internet sources, try to solve the problem independently. In turn, a definite minority uses the services of a professional (eg, podiatrist) in this matter. The most commonly observed biological conditions are corns, cracked heels, ingrown toenails, and calluses. CONCLUSION Patients, despite low awareness of proper care and the risk of complications, rarely decide to seek the help of a specialist in the field of podiatry diseases, even though appropriate care constantly improves foot motor skills. This problem is significant among people chronically ill with somatic diseases that often cause symptoms in the feet and thus reduce the patient's quality of life.

Abstract
Botulinum toxin (BoNT) is a neurotoxin produced by the Clostridium botulinum bacterium with a well-known efficacy and safety profile in the focal idiopathic hyperhidrosis treatment. BoNT comprises seven different neurotoxins; however, only toxins A and B are clinically employed. BoNT is lately practiced in off-label therapies for a variety of skin diseases. Scar prevention, hyperhidrosis, rhytides, eccrine nevus, alopecia, psoriasis, Darier disease, bullous skin disease, pompholyx and Raynaud's phenomenon are some of the novel indications for BoNT in cosmetic and notably non-cosmetic aspects of dermatology. To employ BoNT correctly in clinical practice, we must have a thorough understanding of the functional anatomy of the mimetic muscles. An intensive literature search was conducted to update all dermatology-oriented experiments and clinical trials on the described element of BoNT for this general overview of BoNT use in dermatology. This review aims to analyse the role of BoNT in dermatology and cosmetology.

Abstract
Cellulite is defined as lipodystrophy of the subcutaneous adipose tissue, is a serious problem for about 90% of women. The fight against the symptoms is a challenge for cosmetology and esthetic medicine. The most promising method of skin and subcutaneous tissue imaging appears to be the ultrasound method. The aim of the study was to evaluate the effectiveness of classic and high frequency ultrasonography in monitoring the anti-cellulite treatment. The study involved 144 women at mean age of 40.01 (± 11.90) years. The women were divided into groups: due to age and due to the degree of cellulite. The study was divided into two stages: "before" treatment (stage I) and "after" treatment (stage II), to which patients reported after a monthly anti-cellulite specifics application. In the initial phase, inspection and palpation tests have been executed to determine the severity of cellulite.The Nümberger-Müller cellulite severity assessment scale has been used. All women had a thigh circumference measured at its widest point. Epidermal tests have been performed in all women in order to eliminate allergy to preparation components. Based on the study, it was observed that there was a significant reduction in the thickness of the subcutaneous tissue as a result of therapy. The reduction of thickness of the dermis after treatment may indicate improvement in microcirculation which leads to elimination of edemas. A reduction of thigh circumference, which is one of the main indicative parameters of the therapy effectiveness, has been obtained.

Abstract
The relationship between the skin and the brain is based on their origin from the same ectodermal structure, as well as being affected by similar hormones and neurotransmitters. At this point, psychodermatology forms a common field of study based on the relationship and interaction between psychiatry and dermatology. Cosmetology is a special group within dermatology, and the psychosocial needs of this group differ. In this study, it was aimed to examine the moods such as anxiety, fear and depression experienced by the patients during their application to the cosmetology unit during the COVID‐19 pandemic process and to compare them with the control group. A total of 162 cases, 80 cases from the cosmetology unit meeting the specified conditions and 82 cases as the control group, were retrospectively evaluated. In all participants, the Coronavirus Anxiety Scale (CAS) scores decreased significantly compared to the beginning of the pandemic (P = .001). In the study, while depression (HAM‐D) and general anxiety (HAM‐A) were higher in the cosmetology group compared to the control group (P = .049 and P = .001, respectively), there was no difference in coronavirus anxiety scores (CAS) (P = .24). It should be known that patients who underwent cosmetological procedures during the pandemic period may have anxiety and depression. In this patient group, which requires a special psychodermatological approach, pandemic effects should also be considered. In patients who apply to cosmetology units during the pandemic period, attention should be paid to the relationship between surreal cosmetological process requests and their anxiety and depression state.

Abstract
The in vitro biochemical evaluation of the applicability of polymers carrying active substances (micelles and conjugates) was carried out. Previously designed amphiphilic graft copolymers with retinol or 4-n-butylresorcinol functionalized polymethacrylate backbone and poly(ethylene glycol) (PEG) side chains that included Janus-type heterografted copolymers containing both PEG and poly(ε-caprolactone) (PCL) side chains were applied as micellar carriers. The polymer self-assemblies were convenient to encapsulate arbutin (ARB) as the selected active substances. Moreover, the conjugates of PEG graft copolymers with ferulic acid (FA) or lipoic acid (LA) were also investigated. The permeability of released active substances through a membrane mimicking skin was evaluated by conducting transdermal tests in Franz diffusion cells. The biological response to new carriers with active substances was tested across cell lines, including normal human dermal fibroblasts (NHDF), human epidermal keratinocyte (HaCaT), as well as cancer melanoma (Me45) and metastatic human melanoma (451-Lu), for comparison. These polymer systems were safe and non-cytotoxic at the tested concentrations for healthy skin cell lines according to the MTT test. Cytometric evaluation of cell cycles as well as cell death defined by Annexin-V apoptosis assays and senescence tests showed no significant changes under action of the delivery systems, as compared to the control cells. In vitro tests confirmed the biochemical potential of these antioxidant carriers as beneficial components in cosmetic products, especially applied in the form of masks and eye pads.

Micellar Carriers Based on Amphiphilic PEG/PCL Graft Copolymers for Delivery of Active Substances. Polymers (Basel) 2020; 12:polym12122876. [PMID: 33266207 PMCID: PMC7760728 DOI: 10.3390/polym12122876] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 11/25/2020] [Accepted: 11/29/2020] [Indexed: 12/19/2022] Open
Abstract
Amphiphilic copolymers of alkyne functionalized 2-hydroxyethyl methacrylate (AlHEMA) and poly(ethylene glycol) methyl ether methacrylate (MPEGMA) with graft or V-shaped graft topologies were synthesized. The functionalization of poly(ε-caprolactone) (PCL) with azide group enabled attachment to P(AlHEMA-co-MPEGMA) copolymers via a "click" alkyne-azide reaction. The introduction of PCL as a second side chain type in addition to PEG resulted in heterografted copolymers with modified properties such as biodegradability. "Click" reactions were carried out with efficiencies between 17-70% or 32-50% (for lower molecular weight PCL, 4000 g/mol, or higher molecular weight PCL, 9000 g/mol, respectively) depending on the PEG grafting density. The graft copolymers were self-assembled into micellar superstructures with the ability to encapsulate active substances, such as vitamin C (VitC), arbutin (ARB) or 4-n-butylresorcinol (4nBRE). Drug loading contents (DLC) were obtained in the range of 5-55% (VitC), 39-91% (ARB) and 42-98% (4nBRE). In vitro studies carried out in a phosphate buffer saline (PBS) solution (at pH 7.4 or 5.5) gave the maximum release levels of active substances after 10-240 min depending on the polymer system. Permeation tests in Franz chambers indicated that the bioactive substances after release by micellar systems penetrated through the artificial skin membrane in small amounts, and a majority of the bioactive substances remained inside the membrane, which is satisfactory for most cosmetic applications.

PEG Grafted Polymethacrylates Bearing Antioxidants as a New Class of Polymer Conjugates for Application in Cosmetology. MATERIALS 2020; 13:ma13163455. [PMID: 32764401 PMCID: PMC7475907 DOI: 10.3390/ma13163455] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 07/31/2020] [Accepted: 08/03/2020] [Indexed: 12/19/2022]
Abstract
The amphiphilic copolymers of poly(ethylene glycol) methyl ether methacrylate (MPEGMA) and alkyne functionalized 2-hydroxyethyl methacrylate (AlHEMA) were synthesized by controlled atom transfer radical polymerization (ATRP). The reactions were carried out using the standard ATRP initiator ethyl α-bromoisobutyrate, (EiBBr) and the “bio”initiator bromoester derivative of 4-n-butylresorcinol (4nBREBr2). Two substances with antioxidant activity used in cosmetology, (±)-α-lipoic acid (LA) and ferulic acid (FA), were subjected to esterification reactions to introduce azide groups. The “click” reactions between the alkyne contained copolymers and functionalized acids (LA-N3, FA-N3) were performed to obtain polymer-antioxidant conjugates (P((HEMA-click-FA)-co-MPEGMA) and P((HEMA-click-LA)-co-MPEGMA)). The conjugation was performed with an efficiency of 20–75%. In vitro experiments in a phosphate buffer saline (PBS) solution at neutral conditions demonstrated that the sufficient release was reached after 2.5 h for FA and 1 h for LA. The rapid release kinetics as well as the polymer carriers, which were applied to regulate the delivery of antioxidant substances, are beneficial in cosmetology.

Green synthesis of silver nanoparticles for application in cosmetics. JOURNAL OF ENVIRONMENTAL SCIENCE AND HEALTH. PART A, TOXIC/HAZARDOUS SUBSTANCES & ENVIRONMENTAL ENGINEERING 2020; 55:1304-1320. [PMID: 32715864 DOI: 10.1080/10934529.2020.1790953] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2019] [Revised: 06/12/2020] [Accepted: 06/18/2020] [Indexed: 06/11/2023]
Abstract
In this work, we analyzed the advantages of using silver nanoparticles (AgNPs) synthesized with natural extracts in ultraviolet-visible spectroscopy (UV-Vis) protective cream. The photodegradation properties of the new UV-Vis protective milk show an increase in its absorption band compared to AgNP-free cream. Previous to the study of the AgNPs mixed within the body milk, we studied the optical UV-Vis properties of extracts at different collection times, as they can influence the spectral range of UV-Vis absorption of the hybrid compound (AgNPs + natural extract). Shape and size of the AgNPs differs from the type of reducing agent as well as the concentration of silver nitrate used. We also compared the cytotoxicity in cell lines and the antibacterial effect of the AgNPs without and with organic coating. All these studies showed that we obtained hybrid sun-protective body milk with a high degree of solar protection and with low cytotoxicity at a cellular level, thus improving its protective properties. The synthetized hybrid compound could be a possible cost-affordable alternative for the market.

Abstract
Background Proper nutritional behaviors are one of the most important factors shaping our health, as they influence people's physical and mental state. Good eating habits help prevent many chronic diseases, including cardiovascular disease, type II diabetes, some types of cancer, and osteoporosis. The Polish population aged 20-34 years displays improper nutritional behaviors which may put them at risk of developing diet-dependent diseases in the future. There is a need to assess students' lifestyle, including their eating habits, as it would help adapt already existing education programs. Objective We evaluated and compared eating habits and lifestyle of students studying cosmetology and physiotherapy in association with selected risk factors of civilization diseases. Material and methods We used a standardized dietary questionnaire evaluating respondents' physical activity, smoking and dietary habits. The obtained results were compared with the recommendations from the Polish food-based dietary guidelines. We evaluated respondents' nutritional status based on their anthropometric measurements such as body weight, body height, hips and waist circumferences and then we estimated their body mass index (BMI) and waist hip ratio (WHR). Results Students studying cosmetology and physiotherapy obtained on average 5.3 ±1.5 points based on their compliance with the nutritional recommendations. The academic youth did not meet principles of healthy nutrition according to the given recommendations. There were no significant differences in nutrition status between the faculties, except for products that provide complete protein. Conclusions There is a need to increase nutritional awareness of academic youth, especially students of health-related faculties, because better knowledge on nutrition would help them choose healthier food options.

4- n-Butylresorcinol-Based Linear and Graft Polymethacrylates for Arbutin and Vitamins Delivery by Micellar Systems. Polymers (Basel) 2020; 12:polym12020330. [PMID: 32033296 PMCID: PMC7077416 DOI: 10.3390/polym12020330] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Revised: 01/27/2020] [Accepted: 02/01/2020] [Indexed: 12/17/2022] Open
Abstract
A novel initiator, bromoester modified 4-n-butylresorcinol (4nBREBr2), was prepared and utilized in controlled atom transfer radical polymerization (ATRP) to obtain three series of amphiphilic copolymers. The V-shaped copolymers of methyl methacrylate (MMA), 2-hydroxyethyl methacrylate (HEMA), and poly(ethylene glycol) methyl ether methacrylate (MPEGMA), abbreviated to P(HEMA-co-MMA), P(HEMA-co-MPEGMA), and P(MMA-co-MPEGMA), were synthesized. Moreover, P((HEMA-graft-PEG)-co-MMA) graft copolymers were prepared by combining the pre-polymerization modification of HEMA and a "click" reaction using a "grafting onto" approach. All copolymers could form micelles with encapsulated active substances (vitamin C (VitC), vitamin E (VitE), arbutin (ARB)), which are used in cosmetology. In vitro studies carried out in a PBS solution (pH 7.4) demonstrates that in most cases the maximum release of active substance was after 1 h. The polymeric systems presenting satisfactory encapsulation characteristics and release profiles are attractive micellar carriers of cosmetic substances, which show a positive effect on the skin condition.

Abstract
Astaxanthin is a naturally occurring ketocarotenoid which has been found to have numerous biological functions, with its strong antioxidant property being the prominent feature. The compound has attracted a great amount of interest with respect to its potential utilization in the betterment of human health. In the recent past, astaxanthin has been extensively studied with respect to its possible effect on skin health, with positive results. Astaxanthin has also shown to have anti-inflammatory, immune-modulating, and DNA repair properties, which have further encouraged its usage to maintain skin health and tackle skin damage. In this review article, we highlight the pharmacokinetic profile of the antioxidant in brief and describe the findings of various recent published research articles which studied the effect of astaxanthin in improvement of skin health. We also mention the possible mechanisms which form the basis of the positive dermatological effects of astaxanthin and the potential indications of the antioxidant molecule in cosmetology and dermatology.

Abstract
Fish oil has been broadly reported as a potential supplement to ameliorate the severity of some skin disorders such as photoaging, skin cancer, allergy, dermatitis, cutaneous wounds, and melanogenesis. There has been increasing interest in the relationship of fish oil with skin protection and homeostasis, especially with respect to the omega-3 polyunsaturated fatty acids (PUFAs), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA). The other PUFAs, such as α-linolenic acid (ALA) and linoleic acid (LA), also show a beneficial effect on the skin. The major mechanisms of PUFAs for attenuating cutaneous inflammation are the competition with the inflammatory arachidonic acid and the inhibition of proinflammatory eicosanoid production. On the other hand, PUFAs in fish oil can be the regulators that affect the synthesis and activity of cytokines for promoting wound healing. A systemic review was conducted to demonstrate the association between fish oil supplementation and the benefits to the skin. The following describes the different cosmetic and therapeutic approaches using fatty acids derived from fish oil, especially ALA, LA, DHA, and EPA. This review summarizes the cutaneous application of fish oil and the related fatty acids in the cell-based, animal-based, and clinical models. The research data relating to fish oil treatment of skin disorders suggest a way forward for generating advances in cosmetic and dermatological uses.

Periareolar incision for the management of benign breast tumors. Oncol Lett 2016; 12:3259-3263. [PMID: 27899991 PMCID: PMC5103926 DOI: 10.3892/ol.2016.5117] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2015] [Accepted: 06/27/2016] [Indexed: 12/27/2022] Open
Abstract
Benign breast tumors (BBTs) are common in women. The traditional surgical resection method for the various types of BBT leaves obvious scars and affects the appearance of the breast. The present study introduces the experience of a single institution in the treatment of BBT by periareolar incision. The clinical data of 153 patients (182 breasts) with BBT who had undergone a resection via a periareolar incision between January 2010 and December 2012 in Qilu Hospital, Shandong University (Jinan, Shandong, China), was retrospectively analyzed. All incisions were primary healing. Of the 153 patients, 1 (0.7%) developed a hematoma and 2 (1.3%) developed slight nipple ischemia. No infections or other complications were observed. During 1 month to 3 years of follow-up, the cosmetic effects were assessed. Periareolar incision is not only suitable for all types of breast surgery for benign tumor resection, but also has the advantage of a hidden incision, a small scar, no ischemic necrosis of the nipple areola, high patient satisfaction and good post-operative cosmetic effect. The technique is therefore a good surgical incision choice that is worthy of note.
