Abstract
Royal jelly (RJ) is a highly nutritious natural product with great potential for use in medicine, cosmetics, and as a health-promoting food. This bee product is a mixture of important compounds, such as proteins, vitamins, lipids, minerals, hormones, neurotransmitters, flavonoids, and polyphenols, that underlie the remarkable biological and therapeutic activities of RJ. Various bioactive molecules like 10-hydroxy-2-decenoic acid (10-HDA), antibacterial protein, apisin, the major royal jelly proteins, and specific peptides such as apisimin, royalisin, royalactin, apidaecin, defensin-1, and jelleins are characteristic ingredients of RJ. RJ shows numerous physiological and pharmacological properties, including vasodilatory, hypotensive, antihypercholesterolaemic, antidiabetic, immunomodulatory, anti-inflammatory, antioxidant, anti-aging, neuroprotective, antimicrobial, estrogenic, anti-allergic, anti-osteoporotic, and anti-tumor effects. Moreover, RJ may reduce menopause symptoms and improve the health of the reproductive system, liver, and kidneys, and promote wound healing. This article provides an overview of the molecular mechanisms underlying the beneficial effects of RJ in various diseases, aging, and aging-related complications, with special emphasis on the bioactive components of RJ and their health-promoting properties. The data presented should be an incentive for future clinical studies that hopefully will advance our knowledge about the therapeutic potential of RJ and facilitate the development of novel RJ-based therapeutic opportunities for improving human health and well-being.

Abstract
BACKGROUND Childhood-onset systemic lupus erythematosus (cSLE) is a complex multisystem autoimmune disease often associated with pain, fatigue, and mood-related disturbances. cSLE is associated with increased disease severity and higher rates of mortality as compared to adult onset SLE. Therefore, a multi-faceted approach to care, including the use of non-pharmacologic therapies, is essential to ensure optimal patient outcomes. The use of non-pharmacologic therapies as adjunctive treatments has been shown to be beneficial in adults with SLE, yet, their use and effect is less well understood in cSLE. This is the first systematic review to explore the use and quality of evidence of non-pharmacologic approaches to treat cSLE. METHODS A literature review was performed using PRISMA guidelines. Studies until March 2021 with participants diagnosed with cSLE were included. The quality of the evidence was graded via OCEBM levels of evidence guidelines and bias assessed using Cochrane guidelines. Completed clinical trials (via clinicaltrials.gov) were also searched to identify unpublished results. RESULTS Eleven published studies consisting of 1152 patients met inclusion criteria for this review, as well as three additional studies with unpublished data on clinicaltrial.gov. Of the published trials, four studies used patient education/support, three studies used dietary supplementation, three used forms of psychotherapy (e.g., Cognitive behavioral therapy), and 1 used aerobic exercise to target the following issues: treatment adherence (n = 3), quality of life (n = 3), fatigue (n = 2), pain (n = 2), depressive symptoms (n = 1), anxiety (n = 1), and health-related outcomes including disease severity (n = 3), cardiovascular disease risk (Cardiovascular disease; n = 3), and muscle function (n = 1). Across investigations, the quality of the evidence based on study design was moderate/low. In terms of potential outcomes, dietary supplementation methods were successful in 2 of 3 studies and were associated with improvements in disease activity and fatigue. Aerobic exercise was effective in decreasing resting heart rate and increasing cardiorespiratory capacity. Patient education/support was related to significantly increased treatment adherence and decreased cardiovascular risk markers. Two of the three studies examining the impact of psychotherapy showed improvements (e.g., in treatment adherence, depression and fatigue). CONCLUSION This review identifies several promising non-pharmacologic therapies to use as adjunctive treatments to traditional pharmacologic regimens in health and mental health-related outcomes in patients with cSLE. Future well controlled clinical trials would be beneficial to more rigorously evaluate the effects of non-pharmacologic therapies in pediatric populations.

A Validated Stability-Indicating HPTLC Assay for Determination of 10-Hydroxy-2-Decenoic Acid Content in Royal Jelly Products Using Robust Regression Methods. J Chromatogr Sci 2020; 58:520-534. [PMID: 32390054 DOI: 10.1093/chromsci/bmaa016] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 02/19/2020] [Accepted: 03/16/2020] [Indexed: 11/13/2022]
Abstract
A new, simple, stability-indicating high-performance thin-layer chromatography method was developed for the quantification of 10-hydroxy-2-decenoic acid (10-HDA) in some royal jelly products marketed in Egypt. The used solvent system was chloroform:acetic acid (10:1, v/v) and the bands were measured densitometrically at 210 nm. First- and second-derivative treatments of the data were performed. The present study shows a comparison between three statistical regression methods for handling data: parametric, nonparametric and weighted regression (WR) methods. The developed methods were validated as per International Conference on Harmonization guidelines. To validate the stability-indicating power of the developed analytical method, the royal jelly standard was subjected to forced degradation studies including the effect of hydrolysis, oxidation, photolysis and dry heat. It was found that derivative treatment of the chromatographic response data gives improved quantitation and sensitivity of the chromatographic signals. Weighted regression of the response data is found to be advantageous over the use of both parametric and nonparametric regression models. This was shown by a great enhancement in the accuracy and precision in the analysis of 10-HDA in royal jelly products. The % recovery in case of WR was 99.92 ± 0.16, while % recovery in case of nonparametric and parametric regressions were 99.56 ± 0.25 and 98.63 ± 0.65, respectively.

Abstract
Royal Jelly (RJ) constitutes one of the most popular beehive products and for this reason the use of inexpensive sweeteners during its production remains an important quality issue. In the present study we report results of metabolic profiling of RJ samples obtained after the application of artificial bee-feeding using different feeding protocols. The hydrophilic content of RJ samples was assessed by applying (HILIC)UPLC-MS/MS. In total 96 crude RJ samples were analysed with the developed method. Multivariate statistical analysis revealed clear differentiation between the RJ samples obtained from control (non-fed) bees and samples obtained after feeding. In total 27 out of 57 detected molecules were statistically found to be significantly altered in the different comparisons. Among them some amino acids (e.g. tryptophan, lysine), amino acid derivatives (pyroglutamic acid), amines (cadaverine, TMAO, etc.), carbohydrates and vitamins were found as potential markers. The results of the study could be further used for the development of an LC-MS based analytical tool for RJ quality control assessment.

Abstract
Due to various pharmacological properties, including antioxidative, anti-inflammatory and antibiotic properties, royal jelly (RJ) has been widely consumed in daily diets in numerous countries. In the present study, the effect of RJ on 4T1-bearing mice was investigated. The study was performed by feeding 4T1-bearing mice with RJ using either the prophylactic-therapeutic (PTRJ) or therapeutic (TRJ) method. The experimental results for the PTRJ group demonstrated that the weight of tumor was significantly reduced (RJ 0.5 and 1.5 g/kg); and in the serum, the levels of interleukin (IL)-2 (RJ 0.5 and 1.5 g/kg), interferon (IFN)-α, superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) were significantly elevated, but the concentrations of IL-4 (RJ 0.5 and 1.5 g/kg) and IL-10 (RJ 1.0 g/kg) were significantly decreased. In addition, the activities of T-AOC and glutathione reductase (GR) were significantly improved in the liver, whereas in the kidney, the activities of T-AOC and GR were significantly increased only under the dose of 0.5 g/kg. For the TRJ group, the antitumor effect of RJ was not significant; the change in IL-2, IFN-α, SOD and T-AOC levels in the serum, and the change in T-AOC and GR in liver were similar to those observed in the PTRJ groups. RJ treatment was demonstrated to reduce the development of breast tumor in mice, and simultaneously improve the antioxidant capacity of the serum, liver and kidney, particularly using the prophylactic-therapeutic method. These results corroborated the efficacy of RJ supplementation in diets. The results of the present study suggest that the antioxidant and immunomodulatory activities of RJ serve an important role on antitumor growth.

Abstract
The aim of this study is to establish the scientific benefit of royal jelly (RJ) on prostatic-specific antigen (PSA), post-void residual (PVR) volume and International Prostate Symptom Score (IPSS) in benign prostatic hyperplasia. For the study, a group of 40 men were administered 38 mg of RJ over a period of three months, their PSA values, prostate volumes and the volumes of their transitory prostate zones, PVR and IPPS values were measured at the end of the first month, and at the end of the third month. The results of this study confirm the potential of RJ in reducing PSA scores and improving IPSS values. Since the use of RJ did not lead to any significant reduction in PVR, prostate volume, or to any involution of the transitory zone, it appears that it may only affect the blood marker of prostatic hyperplasia and to improve quality-of-life (QoL) in those patients. Overall, in comparison to phytotherapy and conventional therapy, RJ had similar positive effects on QoL in patients with BPH, however it exhibited markedly better effects on reducing PSA levels in blood. The therapeutical use of RJ exhibited no side effects.

Abstract
BACKGROUND Cancer-related fatigue (CRF) is experienced by 50% to 90% of cancer patients and can severely affect their quality of life and functional capacity. Several randomized trials have recommended various ways to alleviate the symptoms of CRF with or without recourse to medications. OBJECTIVE The aim of this study is to evaluate the effectiveness of processed honey and royal jelly on the symptoms of CRF in cancer patients who are undergoing hormone therapy, chemotherapy, chemo-radiation, or radiotherapy. METHODS Fifty-two participants from the patients who visited the oncology clinic of Shohada-e-Tajrish hospital in Tehran (Iran) between May 2013 and August 2014 were selected and divided into two groups. The study group (26 patients) received processed honey and royal jelly, while the control group received pure honey. Both groups were instructed to consume their 5mL supplement twice daily for 4 weeks. Both groups were assessed at the beginning of the study, after 2 weeks, and then at the end of 4 weeks of treatment. Fatigue was measured using a visual analogue fatigue scale (VAFS) and fatigue severity scale (FSS). The results were compared between the two arms of study, and equality of probability distributions was assessed using a Kolmogorov-Smirnov test. RESULTS The mean age of the 52 patients was 54.84. After two and four weeks of treatment with processed honey and royal jelly, VAFS and FSS due to treatment was better in the study group than in the control group, and the differences were statistically significant (p<0.001, p<0.001, respectively). CONCLUSION To the best of our knowledge, our study provided support for the use of processed honey and royal jelly to ameliorate CRF. The positive results of this study warrant further studies in this field. CLINICAL TRIAL REGISTRATION The study was registered in the Iranian Clinical Trial Registry Center (http://www.irct.ir) with the registration code: IRCT2015081423426N1. FUNDING The authors received no financial support for the research, authorship, and/or publication of this article.

Abstract
BACKGROUND AND OBJECTIVE To our knowledge, no previous studies have focused on the immunomodulatory effects of fresh royal jelly (RJ) administration on systemic lupus erythematosus (SLE) in humans. Our aim was to study the effect of fresh RJ administration on the disease course in children with SLE with some immunological markers (CD4+ and CD8+ regulatory T cells and T lymphocytes apoptosis). METHODS This was an open-label study in which 20 SLE children received 2 g of freshly prepared RJ daily, for 12 weeks. RESULTS The percentages of CD4+ CD25+high FOXP3+cells (CD4+ regulatory T cells) and CD8+CD25+high FOXP3+cells (CD8+ regulatory T cells) were significantly increased after RJ treatment when compared with baseline values. Apoptotic CD4 T lymphocytes were significantly decreased after RJ therapy when compared with baseline values and the control group. CONCLUSION This is the first human study on the effect of RJ supplementation in children with SLE. Our results showed improvements with 3-month RJ treatment with regard to the clinical severity score and laboratory markers for the disease. At this stage, it is a single study with a small number of patients, and a great deal of additional wide-scale randomized controlled studies are needed to critically validate the efficacy of RJ in SLE.

Abstract
BACKGROUND Royal Jelly (RJ), a food item secreted by worker honeybees, is a mixture that contains protein, glucose, lipid, vitamins, and minerals; it is widely used as a commercial medical product. Previous studies have shown that RJ has a number of physiological effects, such as anti-inflammatory, antitumor, antiallergic and antioxidant activities. OBJECTIVES In the present study, the anti-inflammatory properties of RJ were investigated in formalin-induced rat paw edema. MATERIALS AND METHODS In this study, 30 male Wistar albino rats were divided into five equal groups (n = 6) as follows: test groups received different doses (25, 50 and 100 mg/kg, ip) of RJ and a negative control group received normal saline (5 mL/kg) and a positive control group received aspirin (300 mg/kg, i.p). Edema was induced on the right hind paw of the rat by a subplantar injection of 100 µL of formalin (2.5%) after 30 minutes. Paw edema was measured in the rats received the drugs, saline and aspirin before and after the formalin injection during 5 hours, using a plethysmometer. RESULTS The results showed that RJ has a dose-dependent anti-inflammatory effect and the highest anti-inflammatory effect was observed in the doses of 50 and 100 mg/kg. CONCLUSIONS Royal jelly has potent anti-inflammatory effects compared to aspirin and it could be used in the treatment of inflammation. However, further studies are required to determine the active components in RJ responsible for this effect and its mechanism of action.

Royal Jelly-Mediated Prolongevity and Stress Resistance in Caenorhabditis elegans Is Possibly Modulated by the Interplays of DAF-16, SIR-2.1, HCF-1, and 14-3-3 Proteins.

Abstract
Recent studies suggest that royal jelly (RJ) and its related substances may have antiaging properties. However, the molecular mechanisms underlying the beneficial effects remain elusive. We report that the effects of RJ and enzyme-treated RJ (eRJ) on life span and health span in Caenorhabditis elegans (C elegans) are modulated by the sophisticated interplays of DAF-16, SIR-2.1, HCF-1, and 14-3-3 proteins. Dietary supplementation with RJ or eRJ increased C. elegans life span in a dose-dependent manner. The RJ and eRJ consumption increased the tolerance of C elegans to oxidative stress, ultraviolet irradiation, and heat shock stress. Our genetic analyses showed that RJ/eRJ-mediated life-span extension requires insulin/IGF-1 signaling and the activities of DAF-16, SIR-2.1, HCF-1, and FTT-2, a 14-3-3 protein. Earlier studies reported that DAF-16/FOXO, SIR-2.1/SIRT1, FTT-2, and HCF-1 have extensive interplays in worms and mammals. Our present findings suggest that RJ/eRJ-mediated promotion of longevity and stress resistance in C elegans is dependent on these conserved interplays. From an evolutionary point of view, this study not only provides new insights into the molecular mechanisms of RJ's action on health span promotion in C elegans, but also has imperative implications in using RJ/eRJ as nutraceuticals to delay aging and age-related disorders.

Abstract
Background One of the most important challenges in the study of aging is to discover compounds with longevity-promoting activities and to unravel their underlying mechanisms. Royal jelly (RJ) has been reported to possess diverse beneficial properties. Furthermore, protease-treated RJ (pRJ) has additional pharmacological activities. Exactly how RJ and pRJ exert these effects and which of their components are responsible for these effects are largely unknown. The evolutionarily conserved mechanisms that control longevity have been indicated. The purpose of the present study was to determine whether RJ and its related substances exert a lifespan-extending function in the nematode Caenorhabditis elegans and to gain insights into the active agents in RJ and their mechanism of action. Principal Findings We found that both RJ and pRJ extended the lifespan of C. elegans. The lifespan-extending activity of pRJ was enhanced by Octadecyl-silica column chromatography (pRJ-Fraction 5). pRJ-Fr.5 increased the animals' lifespan in part by acting through the FOXO transcription factor DAF-16, the activation of which is known to promote longevity in C. elegans by reducing insulin/IGF-1 signaling (IIS). pRJ-Fr.5 reduced the expression of ins-9, one of the insulin-like peptide genes. Moreover, pRJ-Fr.5 and reduced IIS shared some common features in terms of their effects on gene expression, such as the up-regulation of dod-3 and the down-regulation of dod-19, dao-4 and fkb-4. 10-Hydroxy-2-decenoic acid (10-HDA), which was present at high concentrations in pRJ-Fr.5, increased lifespan independently of DAF-16 activity. Conclusions/Significance These results demonstrate that RJ and its related substances extend lifespan in C. elegans, suggesting that RJ may contain longevity-promoting factors. Further analysis and characterization of the lifespan-extending agents in RJ and pRJ may broaden our understanding of the gene network involved in longevity regulation in diverse species and may lead to the development of nutraceutical interventions in the aging process.
