Efficacy of Pseudo-Ceramide Absorption Into the Stratum Corneum and Effects on Transepidermal Water Loss and the Ceramide Profile: A Randomized Controlled Trial.

Changes in the level or profile of ceramides are associated with decreased stratum corneum (SC) barrier function. Topical application of a pseudo-ceramide (pCer)-containing moisturizer can improve barrier function. Additionally, pCer that absorbs into the SC may improve ceramide profiles. We investigated the relationship between pCer absorption into the SC and SC properties and determined the efficacyof a pCer-containing spray compared with that of a commercial spray without pCer. Patients with self-perceived dry and sensitive skin and decreased barrier function (transepidermal water loss [TEWL] > 10 g/m2h) were randomized into two groups to topically apply a pCer-containing spray (test group; N = 33) or commercial spray without pCer (control group; N = 19) twice daily as a single-blind study. SC function and ceramide properties were investigated before and after 4 weeks of application. In the test group, the ceramide (NP)/(NS) ratio proportionally increased with the pCer application level after 4 weeks of pCer-containing spray application. In the control group, there were no changes in SC function after topical application of the commercially available spray without pCer; however, the SC water content, TEWL, SC cell area, and scaling score improved in the test group. Furthermore, the changes in TEWL in the test group were significantly negatively correlated with the pCer application level. The efficacy of pCer-containing sprays for those who have sensitive skin with impaired barrier function was demonstrated. Furthermore, the improvement in SC barrier function induced by pCer may contribute to normalizing the SC ceramide profile.

Effectiveness of electrocardiogram interpretation education program using mixed learning methods and webpage

AimThis study was conducted to develop an electrocardiogram education program that incorporates an HTML webpage and blended learning methods to enhance electrocardiogram interpretation skills. Through continual and efficient education, the program aims to assist nurses in providing appropriate care and treatment to patients.DesignPre-post design study.MethodsWe developed an electrocardiogram interpretation HTML webpage based on an electrocardiogram interpretation algorithm and implemented an 18-week (2023.5.15 ~ 2023.9.22) electrocardiogram education program, which included daily 5-minute training sessions. Twenty-seven ward nurses were provided with the URL (https://ecgweb.github.io/ECGwebEN) to the electrocardiogram interpretation HTML webpage and shared one electrocardiogram case daily for self-interpretation. Electrocardiogram interpretation performance and confidence were evaluated through questionnaires at three phases: before the program, after 6 weeks of basic electrocardiogram and arrhythmia education, and after 12 weeks of application of the electrocardiogram interpretation HTML webpage and case-based lecture education. The statistical tests used were repeated-measures ANOVA or the Wilcoxon signed-rank test.ResultsThe average score for electrocardiogram interpretation performance before the electrocardiogram education program was 11.89(SD = 3.50), after 6 weeks of basic electrocardiogram and arrhythmia education it was 14.15(SD = 3.68), and after 12 weeks of application of the electrocardiogram interpretation HTML webpage and case-based lecture education, it was 15.56(SD = 3.04). This shows that electrocardiogram interpretation performance significantly improved over time (p < .001). Additionally, post-hoc analysis revealed significant differences in electrocardiogram interpretation performance at each stage, i.e., before, during, and after the application of an electrocardiogram education program. Furthermore, the electrocardiogram interpretation confidence questionnaire score (pre-Median 18, IQR = 5; post-Median 23, IQR = 3) was improved significantly after the completion of the 18-week education program (p < .001).ConclusionsBased on the results of this study, we believe that an electrocardiogram education program using HTML webpage, and a blended teaching method would be very beneficial for maintaining and improving electrocardiogram interpretation skills of clinical nurses. Such a program can help nurses interpret electrocardiograms more effectively and assist them in making important decisions in patient care.

Disruption of Lipid Profile, Glucose Metabolism, and Leptin Levels following Citalopram Administration and High-Carbohydrate and High-Cholesterol Diet in Mice

Introduction: Depression therapy has been linked to negative effects on energy metabolism, which can be attributed to various factors, including an ongoing inflammatory process commonly seen in metabolic disorders. Unhealthy lifestyle choices of patients and the impact of antidepressants on body weight and lipid and glucose metabolism also contribute to these metabolic side effects. Although not as pronounced as other psychopharmaceuticals, the increasing use of antidepressants raises concerns about their potential impact on public health. The study aimed to evaluate the short- and long-term effects of the antidepressant citalopram and its long-term combination with a special diet on metabolic parameters in mice. Methods: Animals were randomly divided into 5 groups – control, control + special diet, citalopram (10 mg/kg for 35 days), citalopram + special diet (10 mg/kg for 35 days), and citalopram (10 mg/kg for 7 days). After a described time of administration, animals were anesthetized, blood and fat and liver tissues were collected. Biochemical parameters of lipid metabolism (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) and glucose were analyzed using spectrophotometry and relevant adipokines and cytokines were evaluated by ELISA. Results: After a week of application of citalopram, we observed dyslipidemia that persisted even at the end of the 5-week experiment. Furthermore, after 5 weeks of citalopram administration, we observed a significant decrease in body weight gain and decreased leptin levels. Changes in lipid metabolism, higher levels of adipokines leptin and PAI-1 were observed due to the special diet after 5 weeks. Conclusions: Our research suggests that the effects of citalopram and a diet on the metabolism of mice can be significant, both in the short term (1 week) and in the long term (5 weeks).

An ionic liquid nanoparticles for dermal targeted delivery and effective anti-wrinkle treatment

BackgroundAging is a natural process that cannot be stopped but retarded. Hydroxypinacolone retinoate (HPR) is a potent anti-wrinkle agent, but with severe irritancy, low stability, and poor water solubility, making it hard to apply in cosmetics. Ionic liquid (IL), as a solvent, displayed improved transdermal efficiency. The role of nano-encapsulation technology in addressing the disadvantages of efficacy application is significant. ObjectiveUsing a combination of ionic liquids and nano-encapsulation technology to obtain HPR-encapsulated ionic liquid nanoparticles (HPR IL-NPs) is an innovative formulation used as a serum, emulsion, and cream in cosmetics for effective anti-wrinkle. MethodsHPR IL-NPs were prepared using matrine coconut oil ionic liquid as a surfactant and permeation enhancer combined with high-pressure homogenization. ResultsThe average particle size in the obtained HPR IL-NPs was 92.8 nm. Applying the HPR IL-NPs increased the content of active substances in the skin by 3.6-fold compared to a traditional HPR-loaded cream. The chick chorioallantois membrane assay showed an RC50 > 100 %, and repeated skin-irritation tests resulted in a mean value of 0.00 points per animal per day. The HPR IL-NPs showed continuous release for 24 h in vitro in the continuous release test. At the same time, the HPR IL-NPs significantly reduced irritation induced by HPR alone. The number and area of facial wrinkles decreased by 25.09 % and 23.65 %, respectively, after one week of application of liquid cream on volunteers. ConclusionIL NPs can significantly improve transdermal absorption efficiency, reduce irritation, and demonstrate high anti-wrinkle efficiency. Supramolecular liquid cream is a promising product in cosmetics for skin care.

Effects of a pH-Regulating Emollient Cream in Mild Atopic Dermatitis Patients with Moderate Localized Lesions

Introduction: Increased skin pH values in patients with atopic dermatitis (AD) contribute to poor antimicrobial and permeability barrier functions of the skin. In practice, the majority of topical preparations available for dry skin conditions do not provide sufficient pH and buffering capacity for maintaining optimum skin surface conditions. To address this issue, we tested a novel zinc lactobionate preparation to determine whether the regular application would lower skin surface pH, and in doing so improve the condition of lesional skin. Methods: The assessment for local severity of AD was done with the Scoring Atopic Dermatitis Index (SCORAD) and skin dryness was assessed by capacitance measurement. Results: The results showed that the test product lowered skin pH and improved AD skin lesions from moderate to mild during 2 weeks of application. In the treated area a lowered pH of about 0.85 units was found. Together with the lowering of pH, the local SCORAD significantly improved from 8.3 on average down to 4.0, while in the untreated area, only a slight improvement (from 8.2 to 6.4) was found. Conclusion: Synergistic effects of the test product’s pH lowering and emollient properties might explain the observed improvements in clinical signs of AD and further research against a comparator would allow the specific contribution of pH modulation to these improvements to be unambiguously isolated.

Prevention of diaper rash in newborns and children under 1 year old: results of a clinical study

Introduction. Modern preventive measures of skin diseases aim to maintain the protective skin barrier. The area that comes in direct contact with the diaper becomes excessively wet, the corneous layer is damaged, which results in a weakened barrier function of the epidermis and the occurrence of an inflammatory process, diaper dermatitis.Aim. To study the clinical efficacy and safety of the use of disposable diapers and pull up pants in full-term and premature infants from birth to 1 year of age to prevent diaper dermatitis.Materials and methods. A total of 45 full-term and premature children under 1 year old with various diseases, including skin eruptions in the area covered by the diaper were included in the study. The proposed care products were used for 14 days on the strict condition that they would be reapplied after defecation and during hygiene procedures in a timely manner. The skin status was assessed visually by a paediatrician from Day 1 to 14 of the study using the M. Odio skin assessment scale.Results. The M. Odio scale evaluation of the skin around waist, buttocks, genitals, anal region, and inguinal folds in all children on Days 1, 7 and 14 showed 0 scores. No adverse events were reported during assessment of the skin status over 14 days of the use of care products.Discussion. The observations were consistent with the previously published data demonstrating that maintenance of the functional characteristics of the skin in the area covered by the diaper and exposed to faecal and urinary enzymes, elevated temperature and humidity prevented the development of diaper dermatitis and skin diseases.Conclusion. No signs of diaper dermatitis were detected in all 45 full-term and premature children under 1 year old, including children with various diseases, during 2 weeks of application of disposable Tanoshi Premium diapers and pull up pants in clinical practice. This fact proves the safety and good tolerance of disposable diapers by children under 1 year old provided that the skin care requirements were met. Tanoshi Premium diapers and pull up pants can be recommended for babies of different ages and body weights, including those with diaper dermatitis.

In vivo effect of recombinant Fsh and Lh administered to meagre (Argyrosomus regius) at the initial stages of sex differentiation

Recombinant gonadotropins, follicle stimulating (rFsh) and luteinizing hormone (rLh), offer the potential to induce gametogenesis in prepubertal fish. This study aimed to determine the in vivo effect of the administration of Argyrosomus regius rFsh and rLh on the reproductive development of prepubertal meagre juveniles at the initial stages of sexual differentiation. Juvenile meagre, 9-months old with mean weight of 219 ± 3.9 g (mean ± SEM) were randomly distributed into nine groups (n = 8 per group). Experimental groups were treated weekly with an acute injection of either rFsh or rLh. Control groups were injected with saline solution. In a 3-week experiment, different groups were administered with different doses 6, 12 or 18 µg kg−1 of rFsh or rLh or saline solution. In a 6-week experiment a group was administered with 12 µg kg−1 of rFsh and a second group with saline solution. The fish were held in a single 10 m3 tank with natural photoperiod (Feb. – March) and temperature 16.1 ± 0.4 °C. At the start of the experiment (n = 8) and at the end of the 3-week experiment, fish were blood sampled and sacrificed. Blood was analysed for 17β-estradiol (E2) and 11-ketotestosterone (11-KT). Gonads and liver were dissected and weighed. Gonads were fixed in Bouińs solution and processed for histological analysis. Juvenile meagre at the start of the experiment were in the initial stages of sexual differentiation, indicated by the presence of the ovarian cavity or testes duct that was surrounded by undifferentiated embryonic germ stem cells and somatic cells. At the end of the 3-week experiment, there was no significant difference in gonadosomatic index (GSI) amongst control (initial and saline treated) and the experimental groups. After three weeks of application of rFsh, rLh or saline all fish presented a similar gonadal structure as at the start of the experiment. However, the incidence of sporadic developing germ cells (principally spermatogonia, spermatocytes, spermatids, but also perinucleolar stage oocytes) generally increased in rGth treated meagre. A mean of 44 % of meagre treated with rFsh or rLh presented sporadic isolated developing germ cells, mainly male cells. Plasma steroid levels of E2 decreased significantly from the start of the experiments to the end. At the end of the experiments there were no differences in plasma E2 amongst Control fish and rGth treated fish. Plasma 11-KT showed no change from the start of the experiment to week 3. However, a significant increase was observed in a proportion of the rFsh group after six weeks of treatment compared to the start of the experiment and the saline control group on week 6. The application of rFsh or rLh to meagre at the initial stages of sex differentiation did not stimulate steroid production until week six (11-KT) and had a limited, but evident effect on the development of sporadic isolated germ cells. However, we conclude that rGth, rFsh or rLh did not stimulate large developmental changes in sexually undifferentiated meagre gonads.

Development of Cosmetic Formulations Containing Olive Extract and Spirulina sp.: Stability and Clinical Efficacy Studies

Cosmetic formulations with natural antioxidants can reduce the oxidative stress caused by solar radiation and pollution. In this context, the aim of this study was to develop and evaluate the clinical efficacy of cosmetic formulations containing olive extract (OE) and Spirulina sp. (SP). For this, rheological behavior, texture, and sensory properties were evaluated. In addition, 31 healthy women with an age of 39 to 60 years, with skin phototypes II and III, and the presence of signs of photoaging on the face were recruited and divided in Group 1 (vehicle formulation) and Group 2 (vehicle with active substances) for this clinical efficacy study. Both groups applied sunscreen daily during the day. The formulations showed non-Newtonian pseudoplastic behaviors and good sensory properties. The clinical evaluation using instrumental measurements showed an increase in skin hydration, an improvement of the skin barrier, and morphological characteristics of the epidermis after 12 weeks of application of the formulations. There was a significant increase in the brightness of the stratum corneum, which suggested a film-forming effect. In addition, both groups had an improvement in the dermis echogenicity, due to the use of sunscreens. Finally, the proposed formulation was effective in protecting the skin and reducing skin changes related to photoaging.

Efficacy and Tolerability of Topical 0.1% Stabilized Bioactive Retinol for Photoaging: A Vehicle-Controlled Integrated Analysis.

Chronic exposure to ultraviolet light photoages skin. Retinol, a precursor molecule to retinoic acid that causes less irritation, is available as a nonprescription, cosmetic retinoid and improves collagen production, skin elasticity, and signs of photoaging. Advances in formulation science have allowed the production of stabilized bioactive retinol formulations. This integrated analysis aims to build on previous studies and further examine the comprehensive efficacy and tolerability of topical 0.1% stabilized bioactive retinol. This analysis included 6 vehicle-controlled studies of 0.1% stabilized bioactive retinol in women with mild-to-moderate signs of photodamage. Across all studies, the same dermatologist investigator assessed overall photodamage; wrinkles on the forehead, cheeks, and undereye area; crow&rsquo;s feet wrinkles and fine lines; lack of even skin tone; and brown spots at baseline and weeks 4, 8, and 12 on a numerical scale. Tolerability was also assessed. Participants (retinol, N=237; vehicle, N=234) had a mean (SD) age of 47.4 (6.6) years. Retinol induced greater improvements from baseline in all signs of photoaging vs vehicle as early as week 4 and through 12 weeks of application. Few participants experienced irritation; all events were mild to moderate and transient. The most common signs of irritation were erythema (n=2) and skin scaling/peeling (n=5). This pooled analysis of 6 vehicle-controlled clinical studies provides new evidence for the efficacy of 0.1% stabilized bioactive retinol in improving signs of photoaging without causing major irritation. Topical 0.1% stabilized bioactive retinol was well tolerated with only a few reported cases of skin irritation. J Drugs Dermatol. 2024;23(4):&nbsp; &nbsp; &nbsp;doi:10.36849/JDD.8124.

Effects of Dental Bleaching Treatment Ingredients and Their Influence on the Hardness of Tooth Enamel

Dental bleaching treatment is currently a trend at the moment. Dental bleaching treatment is not only for aesthetics but a person can become more confident with white teeth. However, it turns out that it has bad effects if it does not comply with correct dental principles, especially in selecting dental bleaching materials. Know the ingredients, effects and methods for whitening teeth, including those that can be used by patients themselves, with or without professional supervision, and products for professional use. This literature study uses the Narrative Review method. References were collected in the form of journals through databases and online websites of BMC Oral Health, PubMed, Wacana and Google Scholar. References are also selected through reference analysis in the form of research, articles and systematic reviews. Carbamide Peroxide can be recommended as a choice of dental bleaching agent because it has a remineralization effect and increases the microhardness of enamel after 8 weeks of application.

Performance of fur clips and livestock markers for identifying vaccinated badgers

Marking free-living wild mammals may be desirable during field studies and management interventions; however, doing so presents practical challenges. In the context of disease management interventions, different approaches such as vaccination and culling may be deployed in adjacent areas resulting in a need to identify previously vaccinated individuals to avoid losses of vaccination benefits. Badgers (Meles meles) have been identified as a wildlife reservoir of bovine tuberculosis in several countries. In England, the primary means of controlling disease in badger populations has been culling, although policy also includes the use of badger vaccination. Vaccination and culling can therefore increasingly take place in adjacent areas. The current means of marking vaccinated badgers is to apply a fur clip; however, the performance of this method has not been assessed. In this study, we assessed the field performance of livestock markers not previously trialled on badgers. We also assessed the performance of fur clips in terms of (a) how likely they are to be detected on recapture and (b) their detectability using remote cameras. None of the livestock markers trialled persisted well on badger fur. Detectability of fur clips on re-captured badgers fell to 50% in adult badgers by approximately 3 months from application. In cubs, detectability fell to less than 50% within 3 weeks of application. We suggest it is highly likely that, if vaccination and culling were carried out in adjacent areas and fur clipping was the primary means of determining vaccination status, a proportion of recently vaccinated badgers would be removed, particularly cubs. This has important implications for disease control, and we suggest options for minimising such losses.

Resistance Training in Cardiovascular Diseases: A Review on Its Effectiveness in Controlling Risk Factors.

Cardiovascular Disease (CVD), a term encompassing various disorders affecting the heart and blood vessels, includes coronary artery disease (CAD). CAD is primarily due to the development of atherosclerotic plaques that disrupt blood flow, oxygenation, and nutrient delivery to the myocardium. Risk factors contributing to CAD progression include smoking, hypertension, diabetes mellitus (DM), dyslipidaemia, and obesity. While aerobic exercise (AE) has shown promising results in controlling CVD risk factors, the impact of resistance training (RT) has not been extensively investigated. This review aims to describe the effects of RT on CVD risk factors based on studies retrieved from PubMed and Google Scholar databases. Both isometric and isotonic RT have been found to decrease systolic blood pressure (SBP), diastolic blood pressure, or mean arterial pressure, with SBP showing a more significant reduction. Hypertensive patients engaging in RT alongside a calorie-restricted diet demonstrated significant improvements in blood pressure. RT is associated with increased nitric oxide bioavailability, sympathetic modulation, and enhanced endothelial function. In type-2 DM patients, 8-12 weeks of RT led to improvements in fasting blood glucose levels, insulin secretion, metabolic syndrome risk, and glucose transporter numbers. Combining AE with RT had a more significant impact in reducing insulin resistance and enhancing blood glucose compared to performing exercises separately. It also significantly decreased total cholesterol, triglycerides, and low-density lipoprotein levels while increasing high-density lipoprotein within 12 weeks of application. However, improvements are considered insignificant when lipid levels are already low to normal at baseline. The administration of RT resulted in weight loss and improved body mass index, with more pronounced effects seen when combining AE with RT and a calorie-restricted diet. Considering these results, the administration of RT, either alone or in combination with AE, proves beneficial in rehabilitating CAD patients by improving various risk factors.

Skin lightening properties of zerumbone cream: A placebo-controlled study.

Despite the demonstrated anti-melanogenic and UV protective effects of Zerumbone (ZER) invitro, there is a lack of clinical trials that have been done to assess these properties. The primary objective of this study was to assess the effectiveness of ZER in lightening the skin tone of human participants with a single-blind approach. Twenty-six participants were randomly assigned to two groups to investigate the application location (left or right volar forearm) for the placebo and ZER creams. Both creams were topically administered to the volar forearms twice daily over a duration of 4 weeks. Initial skin irritation was assessed before and 30 min after applying creams. The melanin and erythema levels were quantified with Mexameter MX 18. Twenty participants were included in the analysis. The cream formulation had excellent physical properties and was well-received by the participants. The initial skin irritation study results indicated that neither of the creams elicited an allergic reaction. The administration of ZER cream resulted in a statistically significant reduction in melanin levels (p < 0.05) after 1 week compared to the initial baseline. Furthermore, after 2 weeks of application, ZER cream demonstrated significant differences in melanin levels compared to placebo (p < 0.05). No adverse effects were observed in the group using ZER cream. ZER demonstrated significant potential as a skin-lightening agent.

Hyperpigmentation in skin of colour: Therapeutical benefits of isobutylamido‐thiazolyl‐resorcinol (Thiamidol®), an effective tyrosinase inhibitor, in phototypes IV–VI

AbstractSkin of colour, defined as Fitzpatrick skin types IV–VI, is especially susceptible to hyperpigmentation concerns such as melasma and postinflammatory hyperpigmentation (PIH). Treating hyperpigmentation in skin of colour is challenging due to increased risk of PIH, which can be induced by the treatments. Isobutylamido‐Thiazolyl‐Resorcinol (ITR), a tyrosinase inhibitor, has previously been identified as an effective and safe solution for hyperpigmentation, inhibiting melanin production without common side effects. This review evaluates available evidence on ITR's efficacy and safety for the management of hyperpigmentation in skin types IV–VI. Three publications reporting four studies were reviewed. Two randomised controlled trials assessed the efficacy and tolerability of ITR for the management of melasma in patients with skin of colour, whereas one randomised clinical trial and one observational real‐world study explored therapeutic benefits for patients with acne‐related PIH. A total of 234 participants completed the four reviewed studies, of which 232 were skin of colour. In a randomised vehicle‐controlled trial, ITR significantly improved Melasma Area and Severity Index scores and quality of life over 24 weeks of application compared to baseline and vehicle. A comparative clinical trial showed ITR, alone or with hyaluronic acid, effectively reduced melasma. A randomised vehicle‐controlled study in patients with acne‐related PIH showed ITR significantly reduced PIH visibility as compared to baseline and vehicle. An observational real‐world study confirmed effective PIH reduction by ITR in a real‐life setting. All studies showed good tolerability of the examined ITR‐containing formulations. The results collectively support ITR as a safe and effective cosmetic solution in skin of colour. ITR emerges as a reliable hyperpigmentation management option for this patients groups, backed by robust methodologies. Future research should include more patients with Fitzpatrick skin type VI and explore potential benefits of combining ITR and laser treatments in skin of colour to reduce PIH risk.

Successful treatment of solar lentigines by topical application of stabilized cysteamine: A vehicle-controlled, double-blind randomized study.

Solar lentigines are common hyperpigmented lesions typically appearing after 50 years of age and associated with negative psychological effects in affected individuals. Topical depigmenting products, such as hydroquinone and even the Kligman's formula, are usually ineffective for treating lentigines. Stabilized cysteamine has been recently shown to be as effective as the modified Kligman's formula for treating melasma. In this study, we evaluated the therapeutic effect of a stabilized cysteamine on solar lentigines. A vehicle-controlled, double-blind, and randomized study was performed on 30 patients with solar lentigines. Stabilized cysteamine or vehicle control creams were applied on solar lentigines on the dorsum of the hands daily for 12 weeks. Clinical measurements with colorimetry and visual analog scale were performed at baseline, 4, 8, and 12 weeks. Statistically significant results were obtained in the cysteamine group versus the vehicle control group. Stabilized cysteamine provided a 40% reduction in colorimetric values (p < 0.002) versus a 2% reduction in the vehicle group (p < 0.405). Cysteamine also provided a 40% reduction in VAS (p < 0.001) versus a 2% reduction in the vehicle group (p < 0.245). Significant improvement of solar lentigines was observed after 12 weeks of application of stabilized cysteamine by all evaluation methods. Stabilized cysteamine represents a highly effective topical treatment for solar lentigines and can be considered as one of the first topical therapies effective on this hyperpigmentary disorder.

Effect of Deficiency-adjusted Macronutrients to Cure Brown Bast Syndrome in Rubber Tree (Hevea brasiliensis)

The brown bast (BB) syndrome causes a 15-20% loss of annual rubber (Hevea brasiliensis) production in Malaysia, and no sustainable remedy has been developed yet. Initial investigation showed a macronutrients deficiency in the bark of affected plants compared to non-affected plants. Therefore, this study was undertaken to know the effect of spraying the deficient macronutrients in curing BB syndrome and increasing latex productivity. The treatments were selected by adjusting deficient nutrients, especially in N, K, and S, compared to healthy plants. The treatments consisted of 13 combinations of nutrient concentrations and a control (no application on healthy rubber trees). One liter of individual treatment per tree was applied on the trunk of BB-affected trees once a week for one month. Data on latex production was collected one week after the last application and continued for up to three months. The results showed that the treatment T9 (0.5% N, 0.8 mg/L K, and 0.2% S), in addition to other prescribed nutrients, made a 100% cure of BB syndrome after three weeks of application, and the nutrient contents of the bark of the affected plants appeared to be similar to the healthy plants. Applying these additional nutrients enhanced the latex production at the rate of 51.85 g/tapping/tree after two months of treatment application under the agro-ecosystem of FELCRA, Simpang Renggam, Johor, Malaysia. It is a new finding to 100% cure BB syndrome and to increase the latex productivity in sustaining the rubber industry in Malaysia.

Formulation and Evaluation of O/W Body Cream Containing Patchouli Oil (Pogostemon cablin Benth.) and Drumstick Oil (Moringa oleifera) as Potential Moisturizing Agent

Various compounds and extracts obtained from a wide variety of plants can be employed as natural antioxidants in cosmetics applications. Patchouli oil (Pogostemon cablin Benth.) and drumstick oil (Moringa oleifera) have the ability to fight free radicals and keep skin hydrated, making them excellent candidates for usage as an active component in cosmetic goods like body cream. This research aims to determine the physical quality of a body cream formulation by subjecting it to an accelerated stability test technique for seven cycles. The preparation was evaluated in each cycle, and the results were analyzed using student's t-test. The evaluation results of body cream preparation showed that there was no significant difference (p&gt;0.05) in the preparation during each cycle. As a result, the formulation of the body cream remained stable throughout the storage term of at least six months, which indicates that it can be utilized for an entire year when kept at room temperature. After two weeks of application on dry skin, it was demonstrated that the formulation had the capacity to increase the amount of moisture contained in the skin (from 30% to 60%). In conclusion, the formulation is potentially produced as commercial cosmetic product in the future.

Anti-spot Effects of Developed Brightening Cream Composed of Three Active Ingredients (Resorcinol, Arbutin and Licorice Root Extract) in Comparison with the Hydroquinone Cream

Aims: The aim of this study was to evaluate the brightening effects of a complex composed of Resorcinol, Arbutin, and Licorice root extract (RAL complex) in patients faced with skin spots compared to a potential hydroquinone compound. Background: Skin spots are defined as excessive accumulation of melanin pigment in different layers of the skin caused by extravagant sun exposure, pregnancy, and other hormonal and genetic factors. Therefore, it is necessary to use appropriate products to treat these types of spots. Objective: To evaluate skin brightness after using the RAL complex, this study was designed in a double-blind randomized trial and the removal of melanin pigment and skin spots was evaluated by different methods. Methods: In this study, the brightening cream formulated with actives comprising the RAL complex in 2.1% w/w concentration and a hydroquinone cream was applied in two groups of 20 women with a mean age of 48 years showing the severity scale 3 of skin pigmentation, separately. This study was conducted to evaluate the brightening effect of this complex compared to a hydroquinone compound after 4, 8, and, 12 weeks of application to the entire face. Results: The results showed the highest percentage of skin brightness 12 weeks after applying the cream, reported at 93% and 89% for RAL complex and hydroquinone compound, respectively. Skin pigmentation rate was measured before and after applying the RAL complex cream with a mexameter device. The highest amount of dark spot removal was seen after using this cream in different areas of the skin. Conclusion: The results showed that the RAL complex was more effective than the hydroquinone compound in removing skin blemishes without any side effects compared to products containing hy-droquinone.

In Vitro and In Vivo Anti-Aging Effect of Coffee Berry Nanoliposomes.

Encapsulation of bioactive compounds in the liposome system provides several advantages, such as enhancing the stability and lowering the toxicity of active compounds. Coffee berry extract (CBE) has previously been established to have in vitro anti-aging properties and to retard the aging of human skin. The purposes of this study were to encapsulate CBE in nanoliposomes and to assess its stability and in vitro anti-aging potential in human dermal fibroblasts (HDF), as well as in healthy human skin. In the HDF model, anti-aging potential was determined by nitric oxide (NO) and collagenase inhibition assays and a superoxide dismutase (SOD) activity assay, whereas in healthy human skin (in vivo), the skin elasticity and brightness were examined. First, liposomal CBE (L-CBE) was created with a particle size of 117.33 ± 2.91 nm, a polydispersity index (PDI) of 0.36 ± 0.03, and a zeta potential of -56.13 ± 1.87 mV. The percentages of encapsulation efficacy (%EE) and loading efficacy (%LE) were 71.26 ± 3.12% and 2.18 ± 0.18%, respectively. After undergoing a 12-week stability test, the L-CBE retained more phenolic content than the free CBE when stored at 4 °C, room temperature, and 45 °C. Compared to free CBE, the L-CBE demonstrated a more consistent, elevated, and prolonged release of phenolics from the lipid system. In human dermal fibroblasts, L-CBE showed lower toxicity, and at its maximum nontoxic concentration (10 mg/mL), it exhibited slightly higher anti-aging effects than CBE, including NO inhibition, enhanced SOD activity, and anti-collagenase activities. In clinical trials (30 volunteer subjects), none of the participants' skin was irritated when the L-CBE, the CBE, or base creams were applied. After 2 weeks of application, the L-CBE and CBE creams both demonstrated an improvement in skin elasticity and a reduction in melanin levels, and after 4 weeks, L-CBE cream showed a significantly greater improvement in skin elasticity and lightening. The results demonstrate that the encapsulation of the CBE in liposomal systems could increase its stability and skin penetration, reduce its toxicity, and maintain its anti-aging effect, which is powerful enough to be exploited in anti-aging and whitening agents for application in cosmetics and cosmeceuticals.

Perioperative Vaginal Estrogen as Adjunct to Native Tissue Vaginal Apical Prolapse Repair

Surgical repairs of apical/uterovaginal prolapse are commonly performed using native tissue pelvic ligaments as the point of attachment for the vaginal cuff after a hysterectomy. Clinicians may recommend vaginal estrogen in an effort to reduce prolapse recurrence, but the effects of intravaginal estrogen on surgical prolapse management are uncertain. To compare the efficacy of perioperative vaginal estrogen vs placebo cream on prolapse recurrence following native tissue surgical prolapse repair. This randomized superiority clinical trial was conducted at 3 tertiary US clinical sites (Texas, Alabama, Rhode Island). Postmenopausal women (N = 206) with bothersome anterior and apical vaginal prolapse interested in surgical repair were enrolled in urogynecology clinics between December 2016 and February 2020. The intervention was 1 g of conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally nightly for 2 weeks and then twice weekly to complete at least 5 weeks of application preoperatively; this continued twice weekly for 12 months postoperatively. Participants underwent a vaginal hysterectomy (if uterus present) and standardized apical fixation (either uterosacral or sacrospinous ligament fixation). The primary outcome was time to failure of prolapse repair by 12 months after surgery defined by at least 1 of the following 3 outcomes: anatomical/objective prolapse of the anterior or posterior walls beyond the hymen or the apex descending more than one-third of the vaginal length, subjective vaginal bulge symptoms, or repeated prolapse treatment. Secondary outcomes included measures of urinary and sexual function, symptoms and signs of urogenital atrophy, and adverse events. Of 206 postmenopausal women, 199 were randomized and 186 underwent surgery. The mean (SD) age of participants was 65 (6.7) years. The primary outcome was not significantly different for women receiving vaginal estrogen vs placebo through 12 months: 12-month failure incidence of 19% (n = 20) for vaginal estrogen vs 9% (n = 10) for placebo (adjusted hazard ratio, 1.97 [95% CI, 0.92-4.22]), with the anatomic recurrence component being most common, rather than vaginal bulge symptoms or prolapse repeated treatment. Masked surgeon assessment of vaginal tissue quality and estrogenization was significantly better in the vaginal estrogen group at the time of the operation. In the subset of participants with at least moderately bothersome vaginal atrophy symptoms at baseline (n = 109), the vaginal atrophy score for most bothersome symptom was significantly better at 12 months with vaginal estrogen. Adjunctive perioperative vaginal estrogen application did not improve surgical success rates after native tissue transvaginal prolapse repair. ClinicalTrials.gov Identifier: NCT02431897.
