Ramesh T. Osteogenic differentiation potential of human bone marrow-derived mesenchymal stem cells enhanced by bacoside-A. Cell Biochem Funct 2020; 39:148-158. [PMID: 33137853 DOI: 10.1002/cbf.3596] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Revised: 09/30/2020] [Accepted: 10/07/2020] [Indexed: 01/18/2023]
Abstract
Stem cell therapy is growing rapidly to treat numerous diseases including bone-associated diseases. Mesenchymal stem cells (MSCs) are most commonly preferred to treat bone diseases because it possesses high osteogenic potency. Though, to obtain maximum osteogenic efficiency of MSCs is challenging. Therefore, this study was planned to evaluate the osteogenic efficiency of human bone marrow derived mesenchymal stem cells (hBMSCs) by bacoside-A. This study was investigated the activity of alkaline phosphatase (ALP) and expressions of the genes specific to osteogenic regulation mainly runt-related transcription factor 2 (Runx2), osterix (Osx), osteocalcin (OCN) and collagen type Iα1 (Col I α1) in hBMSCs cultured under osteogenic conditions at different concentrations of bacoside-A for 14 days. The results of this study depicted significant upregulation in the activity of ALP and expressions of osteogenic regulator genes in bacoside-A treated cells when compared with control cells. Besides, expressions of glycogen synthase kinase-3β (GSK-3β) and Wnt/β-catenin were evaluated; these expressions were also significantly increased in bacoside-A treated cells when compared with control cells. This result provides a further supporting evidence of bacoside-A role on osteogenesis in hBMSCs. The present study suggest that bacoside-A will be applied to ameliorate the process of osteogenesis in hBMSCs to repair damaged bone structure during MSC-based therapy; this will be an excellent and auspicious treatment for bone-associated disorders including osteoporosis. Significance of the study Osteoporosis is a bone metabolic disorder characterized by an imbalance between the activity of osteoblastic bone formation and osteoclastic bone resorption that disrupts the bone microarchitecture. Current anti-osteoporotic drugs are inhibiting bone resorption, but they are unable to restore the bone structure due to extreme bone remodelling process and causes numerous side effects. The finding of natural bioactive compounds with osteogenic property is very essential for osteoporosis treatment. This study was reported that bacoside-A ameliorated osteogenic differentiation of hBMSCs through upregulation of osteogenic differentiation genes and Wnt/β-catenin signalling pathway. This result is indicating that bacoside-A may be useful for osteoporosis treatments.

Estradiol treatment improves biological rhythms in a preclinical rat model of menopause. Neurobiol Aging 2019; 83:1-10. [PMID: 31585360 DOI: 10.1016/j.neurobiolaging.2019.08.029] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2019] [Revised: 08/27/2019] [Accepted: 08/30/2019] [Indexed: 01/14/2023]
Abstract
The perimenopausal transition at middle age is often associated with hot flashes and sleep disruptions, metabolic changes, and other symptoms. Whereas the mechanisms for these processes are incompletely understood, both aging (AG) and a loss of ovarian estrogens play contributing roles. Furthermore, the timing of when estradiol (E) treatment should commence and for how long are key clinical questions in the management of symptoms. Using a rat model of surgical menopause, we determined the effects of regimens of E treatment with differing time at onset and duration of treatment on diurnal rhythms of activity and core temperature and on food intake and body weight. Reproductively mature (MAT, ∼4 months) or AG (∼11 months) female rats were ovariectomized, implanted intraperitoneally with a telemetry device, and given either a vehicle (V) or E subcutaneous capsule implantation. Rats were remotely recorded for 10 days per month for 3 (MAT) or 6 (AG) months. To ascertain whether delayed onset of treatment affected rhythms, a subset of AG-V rats had their capsules switched to E at the end of 3 months. Another set of AG-E rats had their capsules removed at 3 months to determine whether beneficial effects of E would persist. Overall, activity and temperature mesor, robustness, and amplitude declined with AG. Compared to V treatment, E-treated rats showed (1) better maintenance of body weight and food intake; (2) higher, more consolidated activity and temperature rhythms; and (3) higher activity and temperature robustness and amplitude. In the AG arm of the study, switching treatment from V to E or E to V quickly reversed these patterns. Thus, the presence of E was the dominant factor in determining stability and amplitude of locomotor activity and temperature rhythms. As a whole, the results show benefits of E treatment, even with a delay, on biological rhythms and physiological functions.

Abstract
OBJECTIVES To compare the effects of a 12-week treatment with Pueraria mirifica (PM) gel or a conjugated estrogen cream on vaginal maturation index, vaginal symptom score, vaginal health assessment score, and vaginal flora in postmenopausal women. METHODS In a prospective, noninferiority, randomized controlled study, 82 postmenopausal women with at least one vulvovaginal symptom, that is, dryness, soreness, irritation, dyspareunia, or discharge, were recruited. Participants were randomly assigned into two groups for treatment with either PM gel or conjugated estrogen cream (CEE). The treatment regimen consisted of application of 0.5 g of product intravaginally daily for 2 weeks, and then decreased to three times per week for 10 weeks. Vaginal maturation index, vaginal symptoms score, and vaginal health assessment score were evaluated before the beginning of the study and at 6 weeks and 12 weeks after treatment with PM or CEE. RESULTS The vaginal maturation index increased significantly in both treatment groups at week 12, from 22.44 ± 22.28 to 47.56 ± 29.00 and from 27.07 ± 26.12 to 66.90 ± 22.42 in the PM and the CEE groups, respectively (P < 0.05). A significantly higher effect was, however, observed in the CEE group (P < 0.05). Vaginal symptom scores decreased significantly after treatment in both groups, from 4.37 ± 2.79 to 0.95 ± 1.88 and from 4.15 ± 2.16 to 0.68 ± 1.64 in the PM and the CEE groups, respectively (P < 0.05), with no statistically significant different between the two groups (P > 0.05). CONCLUSIONS The use of a 12-week treatment regimen with Pueraria mirifica gel was shown to be efficacious and safe for the treatment of vulvovaginal atrophy. Conjugated estrogen cream was found to be more effective compared to Pueraria mirifica gel in improving signs of vaginal atrophy and restoring vaginal epithelium at 6 and 12 weeks.

Abstract
Glycyrrhiza glabra (G. glabra) has been used as a flavoring and sweetener agent, in addition to its therapeutic properties. It is rich in phytoestrogen and may prevent osteoporosis caused by estrogen deficiency; however, there is no evidence for its effects on proliferation and osteogenesis in mesenchymal stem cells. So, we were encouraged to investigate whether the ethyl acetate extract of licorice root as a source of phytoestrogen can act similar to estrogen in cell culture. Furthermore, the analysis of the licorice extract (LE) based on HPLC-DAD-ESI-MS indicated that LE comprises phytoestrogen compounds, such as glabridin and glabrene. In this study, the effects of LE on proliferation of human bone-marrow mesenchymal stem cells (hBM-MSCs) were investigated using MTT assay. In addition, its effects on the osteogenesis were evaluated using alkaline phosphatase activity (ALP), calcium deposition, and bone specific gene expression such as ALP, osteocalcin, Runx2, and BMP-2. The quantitative gene expression was studied by real-time RT-PCR. Our results showed a significant increase in proliferation in presence of LE in concentration 10-50 µg/mL. The differentiation of hBM-MSCs increased in doses of LE (10-25 µg/mL) compared to the control group. The effects of LE were similar to those of 17β-estradiol (E2) (10-8 M) and were abolished by ICI 182,780 an antagonist of estrogen receptor (ER) (10-7), indicating that the stimulatory effects of LE occur through estrogen receptor-mediated mechanism . Taking these into account, LE may be a potential candidate for prevention of osteoporosis in menopausal women.

Abstract
OBJECTIVE To estimate long term trends in estrogen-progestin prevalence for the U.S. female population by year and age. METHODS We integrated data on oral estrogen-progestin use from the National Health and Nutrition Examination Survey 1999-2010 with data from the National Prescription Audit 1970-2003. Distributions of estrogen-progestin by age from the National Health and Nutrition Examination Survey were applied to the prescription data, and calibration and interpolation procedures were used to generate estrogen-progestin prevalence estimates by single year of age and single calendar year for 1970-2010. RESULTS Estimated prevalence of oral estrogen-progestin was below 0.5% in the 1970s, began to rise in the early 1980s, and almost tripled between 1990 and the late 1990s. The age-adjusted prevalence for women aged 45-64 years peaked at 13.5% in 1999 with highest use among 57-year-old women (23.2%). Prevalence of estrogen-progestin use declined dramatically in the early 2000s with only 2.7% of women aged 45-64 years using estrogen-progestin in 2010, which is comparable to prevalence levels in the mid-1980s. CONCLUSION The dramatic rise and fall of estrogen-progestin use over the past 40 years provides an illuminating case study of prescription practices before, during, and after the development of evidence regarding benefits and harms. LEVEL OF EVIDENCE : II.

Abstract
Menopause is caused by changes in the function of the hypothalamic-pituitary-gonadal axis that controls reproduction. Hypophysiotropic gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus orchestrate the activity of this axis and are regulated by hormonal feedback loops. The mechanisms by which GnRH responds to the primary regulatory sex steroid hormone, estradiol (E2), are still poorly understood in the context of menopause. Our goal was to determine whether the G protein-coupled estrogen receptor (GPER) is co-expressed in adult primate GnRH neurons and whether this changes with aging and/or E2 treatment. We used immunofluorescence double-labeling to characterize the co-expression of GPER in GnRH perikarya and terminals in the hypothalamus. Young and aged rhesus macaques were ovariectomized and given long-term (~2-year) hormone treatments (E2, E2 + progesterone, or vehicle) selected to mimic currently prescribed hormone replacement therapies used for the alleviation of menopausal symptoms in women. We found that about half of GnRH perikarya co-expressed GPER, while only about 12% of GnRH processes and terminals in the median eminence (ME) were double-labeled. Additionally, many GPER-labeled processes were in direct contact with GnRH neurons, often wrapped around the perikarya and processes and in close proximity in the ME. These results extend prior work by showing robust co-localization of GPER in GnRH in a clinically relevant model, and they support the possibility that GPER-mediated E2 regulation of GnRH occurs both in the soma and terminals in nonhuman primates.

Abstract
Estrogenic hormones (estrone (E1), 17β-estradiol (E2), estriol (E3), 17α-ethinylestradiol (EE2)) are the major contributor to the total estrogenicity in waterways. Presence of these compounds in biosolids is also causing concern in terms of their use as soil amendment. In comparison with wastewater treatment, removal of estrogenic compounds in sewage sludge has received less attention. This paper presents a literature review regarding the source and occurrence of these pollutants in our environment. The removal pathways of estrogenic compounds in engineered systems, such as full-scale wastewater treatment plants (WWTPs), are also discussed. Review of the fate studies revealed that activated sludge system with nutrient removal shows very high (>90%) removal of estrogenic hormones in most of the cases. Although, aerobic digestion showed better attenuation of estrogenic compounds, anaerobic digestion increased the overall estrogenicity of biosolids. Finally, this paper highlights the challenges involved in analytical determination of these compounds in sewage sludge matrix.

Abstract
OBJECTIVE Short-term declines in postmenopausal hormone use were observed after the Women's Health Initiative trial results in 2002. Although concerns about the trial's generalizability have been expressed, long-term trends in hormone use in a nationally representative sample have not been reported. We sought to evaluate national trends in the prevalence of hormone use and to assess variation by type of formulation and patient characteristics. METHODS We examined postmenopausal hormone use during 1999-2010 using cross-sectional data from 10,107 women aged 40 years and older in the National Health and Nutrition Examination Survey. RESULTS In 1999-2000, the prevalence of oral postmenopausal hormone use was 22.4% (95% confidence interval [CI] 19.0-25.8) overall, 13.3% (95% CI 11.0-15.5) for estrogen only, and 8.3% (95% CI 6.2-10.4) for estrogen plus progestin. A sharp decline in use of all formulations occurred in 2003-2004, when the overall prevalence decreased to 11.9% (95% CI 9.6-14.2). This decline was initially limited to non-Hispanic whites; use among non-Hispanic blacks and Hispanics did not decline substantially until 2005-2006. Hormone use continued to decline through 2009-2010 across all patient demographic groups, with the current prevalence now at 4.7% (95% CI 3.3-6.1) overall, 2.7% (95% CI 1.9-3.4) for estrogen only, and 1.7% (95% CI 0.7-2.7) for estrogen plus progestin. Patient characteristics currently associated with hormone use include history of hysterectomy, non-Hispanic white race or ethnicity, and income. CONCLUSION Postmenopausal hormone use in the United States has declined in a sustained fashion to low levels across a wide variety of patient subgroups.

Abstract
Suan-Zao-Ren (SZR) decoction, consisting of Ziziphi Spinosae Semen, Poria, Chuanxiong Rhizoma, Anemarrhenae Rhizoma and Glycyrrhizae Radix Et Rhizoma, is a Traditional Chinese Medicine prescription, clinically used for the treatment of insomnia. The objective of this study was to develop a sensitive and reliable UFLC-MS/MS method for simultaneous quantitation of spinosin, mangiferin and ferulic acid, the main active ingredients in SZR decoction, and to compare the pharmacokinetics of these active ingredients in normal and insomnic rats orally administrated with the prescription. Analytes and IS were separated on a Shim-pack XR-ODS column (75 mm × 3.0 mm, 2.2 µm particles) using gradient elution with the mobile phase consisting of methanol and 0.1% formic acid in water at a flow rate of 0.4 mL/min. The detection of the analytes was performed on 4000Q UFLC-MS/MS system with turbo ion spray source in the negative ion and multiple reaction-monitoring mode. The lower limits of quantification were 1, 6 and 1 ng/mL for spinosin, mangiferin and ferulic acid, respectively. Intra- and inter-day precision and accuracy of analytes were well within acceptance criteria (15%). The mean extraction recoveries of analytes and IS from rats plasma were all more than 85.0%. The validated method has been successfully applied to comparing pharmacokinetic profiles of analytes in rat plasma. The results indicated that no significant difference in pharmacokinetic parameters of ferulic acid was observed between two groups, while absorptions of spinosin and mangiferin in insomnic group were significantly lower than those in normal group.

Abstract
Knowledge of determinants of change in diet quality is needed, but it is relatively limited to date and mostly available from cross-sectional studies. We investigated longitudinal change in diet quality and its associations with period of birth (birth cohort) and socio-demographic and lifestyle characteristics. We used dietary intake data collected by FFQ in 1992, 1996, and 2007 from a population-based random sample of adults comprising 1511 men and women aged 25-75 y at baseline and applied generalized estimating equations to examine determinants of long-term change in diet quality, calculated using a diet quality index reflecting dietary guidelines for Australian adults. Information on socio-demographic and lifestyle factors was derived from self-reported questionnaires. Multivariable models, stratified by sex, were adjusted for confounders. We showed that there was an overall increase in diet quality in both men and women, but scores related to intake of fruit (men only), cereals, and food variety decreased during a 15-y follow-up. Younger age, higher occupational level (men only), and low to medium level of physical activity and hormone replacement therapy use in women were independently associated with greater improvement in diet quality over time (P < 0.05). In conclusion, despite an overall improvement in diet quality over time, this study suggests that efforts to further improve diet quality in Australia should focus on increasing consumption of fruit, cereals, and a greater variety of foods. More evidence from studies that assess change in dietary quality in longitudinal studies is needed to corroborate these findings.

Abstract
OBJECTIVE To present a case of primary menopausal insomnia with hot flashes to introduce recent changes in technology and nomenclature of sleep medicine and to review presentation, diagnosis, and therapies for menopausal insomnia. METHODS Clinical findings and results of sleep evaluation in the menopausal study patient are presented with details about polysomnography performed before and after therapy with pregabalin. RESULTS A 56.5-year-old female athlete with severe hot flashes and insomnia of 12 years' duration was treated with pregabalin, which ameliorated the hot flashes and sweats and improved sleep quality and architecture. Menopause is associated with hormonal and metabolic changes that disrupt sleep. Disruption of sleep can in turn lead to morbidity and metabolic sequelae. Hormonal treatment, although effective, carries risks unacceptable to many patients and physicians. To date, nonhormonal therapies of symptomatic menopause have not been objectively studied for effects on sleep efficiency and architecture. Primary menopausal insomnia is insomnia associated with menopause and not attributable to secondary causes. Polysomnographically, it seems characterized by a high percentage of slow-wave (N3) sleep, decreased rapid eye movement sleep, cyclic alternating pattern, and arousals. CONCLUSIONS Primary menopausal insomnia is probably mediated through a mechanism separate from hot flashes, and one can occur without the other. Thermal dys-regulation and sleep abnormalities of menopause are probably related to more general changes mediated through loss of estrogenic effects on neuronal modulation of energy metabolism, and more clinical direction is expected as this research field develops. Identification of sleep disorders in menopausal women is important, and polysomnographic evaluation is underused in both clinical and research evaluations of metabolic disturbances.

Levels of measured biological risk in the population were reduced in recent years largely because of the expanded use of prescription drugs. The increased use of antihypertensives and, to a lesser extent, lipid-lowering drugs was a likely cause of significant mortality reduction. Blacks and persons with lower educational attainment experience higher levels of biological risk factors, more diseases, and more frailty; these differences are the sources of higher mortality for these groups. Hispanics are less likely to have a higher prevalence of risk factors and diseases than the non-Hispanic population, providing further understanding of the "Hispanic paradox." Almost every examined indicator of biological risk, disease, and frailty is related to higher mortality, indicating how incorporation of this information provides a fuller understanding of the morbidity process.

Abstract
Recent observed feminization of aquatic animals has raised concerns about estrogenic compounds in water supplies and the potential for these chemicals to reach drinking water. Public perception frequently attributes this feminization to oral contraceptives (OCs) in wastewater and raises concerns that exposure to OCs in drinking water may contribute to the recent rise in human reproductive problems. This paper reviews the literature regarding various sources of estrogens, in surface, source and drinking water, with an emphasis on the active molecule that comes from OCs. It includes discussion of the various agricultural, industrial, and municipal sources and outlines the contributions of estrogenic chemicals to the estrogenicity of waterways and estimates that the risk of exposure to synthetic estrogens in drinking water on human health is negligible. This paper also provides recommendations for strategies to better understand all the potential sources of estrogenic compounds in the environment and possibilities to reduce the levels of estrogenic chemicals in the water supply.

Abstract
Many factors have been considered in evaluations of the risk-benefit balance of hormone replacement therapy (HRT), used for treating menopausal symptoms in women, but not its potential risks for the environment We investigated the possible environmental health implications of conjugated equine estrogens (CEEs), the most common components of HRT, including their discharge into the environment, their uptake, potency, and ability to induce biological effects in wildlife. Influents and effluents from four U.K. sewage treatment works (STWs), and bile of effluent-exposed fish, were screened for six equine estrogens. In vitro estrogen receptor (ER) activation assays were applied in humans and fish to compare their potencies, followed by in vivo exposures of fish to equine estrogens and evaluation of bioaccumulation, estrogenic responses, and ER gene expression. The equine estrogen equilenin (Eqn), and its metabolite 17beta-dihydroequilenin (17beta-Eqn), were detected by tandem GC-MSMS in all STW influent samples and 83% of STW effluent samples analyzed, respectively, at low concentrations (0.07-2.6 ng/L) and were taken-up into effluent-exposed fish. As occurs in humans, these estrogens bound to and activated the fish ERs, with potencies at ERalpha 2.4-3490% of thatfor 17beta-estradiol. Exposure of fish for 21 days to Eqn and 17beta-Eqn induced estrogenic responses including hepatic growth and vitellogenin production at concentrations as low as 0.6-4.2 ng/L. Associated with these effects were inductions of hepatic ERalpha and ERbeta1 gene expression, suggesting ER-mediated mechanism(s) of action. These data provide evidence for the discharge of equine estrogens from HRT into the aquatic environment and highlight a strong likelihood that these compounds contribute to feminization in exposed wildlife.
