Abstract
Testosterone deficiency has been reported to accelerate nonalcoholic fatty liver disease (NAFLD). However, there are minimal data on the risk of NAFLD in transgender women and the treatment of NAFLD in this population. This study aimed to investigate the treatment effects and the mechanisms of action of genistein and sex hormones in orchiectomized (ORX) rats with nonalcoholic steatohepatitis (NASH) induced by a high fat high fructose diet (HFHF). Seven-week old male Sprague-Dawley rats were randomly divided into 7 groups (n = 6 each group); 1) control group, 2) ORX + standard diet group, 3) HFHF group, 4) ORX + HFHF group, 5) ORX + HFHF diet + testosterone group (50 mg/kg body weight (BW) once weekly), 6) ORX + HFHF diet + estradiol group (1.6 mg/kg BW daily), and 7) ORX + HFHF diet + genistein group (16 mg/kg BW daily). The duration of treatment was 6 weeks. Liver tissue was used for histological examination by hematoxylin and eosin staining and hepatic fat measurement by Oil Red O staining. Protein expression levels of histone deacetylase3 (HDAC3) and peroxisome proliferator-activated receptor delta (PPARδ) were analyzed by immunoblotting. Hepatic nuclear factor (NF)-ĸB expression was evaluated by immunohistochemistry. Rats in the ORX + HFHF group had the highest degree of hepatic steatosis, lobular inflammation, hepatocyte ballooning and the highest percentage of positive Oil Red O staining area among all groups. The expression of HDAC3 and PPARδ was downregulated, while NF-ĸB expression was upregulated in the ORX + HFHF group when compared with control and ORX + standard diet groups. Testosterone, estradiol and genistein treatment improved histological features of NASH together with the reversal of HDAC3, PPARδ and NF-ĸB protein expression comparing with the ORX + HFHF group. In summary, genistein and sex hormone treatment could alleviate NASH through the up-regulation of HDAC3 and PPARδ, and the suppression of NF-ĸB expression.

Abstract
Central Diabetes Insipidus (CDI) is mainly associated with structural pathologies of the hypothalamic-pituitary area. Etiologies underlying CDI are identified in most patients, however idiopathic CDI is reported in 13-17% of cases after excluding other etiologies. The Hypopituitarism ENEA Rare Observational Study (HEROS study) retrospectively collected data of patients with idiopathic CDI from 14 pituitary centers in 9 countries. The cohort included 92 patients (59 females 64%), mean age at diagnosis was 35.4 ± 20.7 years, and a mean follow up of 19.1 ± 13.5 years following CDI diagnosis. In 6 women, diagnosis was related to pregnancy. Of 83 patients with available data on pituitary imaging, 40(48%) had normal sellar imaging, and 43(52%) had pathology of the posterior pituitary or the stalk, including loss of the bright spot, posterior pituitary atrophy or stalk enlargement. Anterior pituitary hormone deficiencies at presentation included hypogonadism in 6 (6.5%) patients (5 females), and hypocortisolism in one; during follow-up new anterior pituitary deficiencies developed in 6 patients. Replacement treatment with desmopressin was given to all patients except one, usually with an oral preparation. During follow up, no underlying disease causing CDI was identified in any patient. Patients with idiopathic CDI following investigation at baseline are stable with no specific etiology depicted during long-term follow-up.

Tibial nerve stimulation increases vaginal blood perfusion and bone mineral density and yield load in ovariectomized rat menopause model. Int Urogynecol J 2022; 33:3543-3553.

Abstract
INTRODUCTION AND HYPOTHESIS Human menopause transition and post-menopausal syndrome, driven by reduced ovarian activity and estrogen levels, are associated with an increased risk for symptoms including but not limited to sexual dysfunction, metabolic disease, and osteoporosis. Current treatments are limited in efficacy and may have adverse consequences, so investigation for additional treatment options is necessary. Previous studies have demonstrated that percutaneous tibial nerve stimulation (PTNS) and electro-acupuncture near the tibial nerve are minimally invasive treatments that increase vaginal blood perfusion or serum estrogen in the rat model. We hypothesized that PTNS would protect against harmful reproductive and systemic changes associated with menopause. METHODS We examined the effects of twice-weekly PTNS (0.2 ms pulse width, 20 Hz, 2× motor threshold) under ketamine-xylazine anesthesia in ovariectomized (OVX) female Sprague-Dawley rats on menopause-associated physiological parameters including serum estradiol, body weight, blood glucose, bone health, and vaginal blood perfusion. Rats were split into three groups (n = 10 per group): (1) intact control (no stimulation), (2) OVX control (no stimulation), and (3) OVX stimulation (treatment group). RESULTS PTNS did not affect serum estradiol levels, body weight, or blood glucose. PTNS transiently increased vaginal blood perfusion during stimulation for up to 5 weeks after OVX and increased areal bone mineral density and yield load of the right femur (side of stimulation) compared to the unstimulated OVX control. CONCLUSIONS PTNS may ameliorate some symptoms associated with menopause. Additional studies to elucidate the full potential of PTNS on menopause-associated symptoms under different experimental conditions are warranted.

Abstract
Natural herbal medicines have been developed for the treatment and prevention of women’s menopausal symptoms. In this study, we investigated the anti-menopausal effects of Cornus officinalis (CO) and Ribes fasciculatum (RF) extracts in 3T3-L1 preadipocytes, MC3T3-E1 preosteoblasts, and COV434 granulosa cells in vitro and ovariectomized (OVX) ddY mice in vivo. Combination treatment of CO and RF extract at 7:3 ratio inhibited lipid accumulation via Plin1 and Adipoq downregulation in a cocktail of dexamethasone, 3-isobutyl-1-methylxanthine, and insulin (DMI)-induced differentiated 3T3-L1 cells. In addition, CO + RF treatment significantly enhanced osteoblastic differentiation, with mineralized nodule formation occurring through the upregulation of osteoblast-inducing markers in osteoblastic MC3T3-E1 cells. Increased production of estradiol and mRNA expression of ERα (ESR1) were observed in androstenedione-induced COV434 granulosa cells treated with the CO + RF extract. In CO + RF-treated mice, fatty hepatocyte deposition and abdominal visceral fat tissues reduced with OVX-induced uterine atrophy. Furthermore, bone mineral density and bone mineral content were significantly enhanced by CO + RF in mouse models of ovariectomy-induced femoral bone loss. Taken together, our findings suggested that CO + RF promoted estrogenic activity and had anti-obesity and anti-osteoporotic effects in vitro and in vivo. Thus, a combination of CO and RF extracts may be a good therapeutic strategy for managing women’s menopausal syndromes.

Abstract
BACKGROUND & OBJECTIVES Vaginal atrophy is characterized by thinning of vaginal epithelial layers and decreased local blood flow. We aimed to evaluate the regenerative effects of Adipose derived mesenchymal stem cells (ADMSC) and Bone marrow derived mesenchymal stem cells (BMDSC) on vaginal atrophy in rat menopause model. MATERIALS AND METHODS Rats were randomly divided into 4 (four) groups: sham, control, ADMSC, BMDSC. Vaginal epithelial thickness, structure of the lamina propria, blood vessels in the lamina propria, collagen deposition, and muscle structure were evaluated. Anti ER α, VEGF, VEGFR 1, Bax and bcl-2 antibodies were analyzed. Beta actin gene was used as endogenous control. Genetical differences among the groups were compared by using Kruskal Wallis and Mann Whitney U test. p < 0.05 was regarded as statistically significant. RESULTS Epithelial thickness of ADMSC group was higher than control group, but less than sham group Epithelial thickness of BMDSC group was less than sham group. Lamina propria and muscle tissue of ADMSC and BMDSC groups were found to be similar to sham group. VEGFR-1, VEGF, Bax and ER-α staining levels were higher in ADMSC and BMDSC groups than control group. ADMSC group stained stronger with VEGFR-1 and VEGF than BMDSC group. Bcl-2 staining level was increased in ADMSC applied group. No statistically significant difference was detected in Bax and Bcl-2 genes and Bax-/Bcl-2 ratio. CONCLUSIONS Although genetic expression might have ended and could not be significantly demonstrated, histological and immunohistochemical results favor ADMSC application in vaginal atrophy rather than BMDSC.

Estrogen Replacement Regulates Vaginal Innervations in Ovariectomized Adult Virgin Rats: A Histological Study. BIOMED RESEARCH INTERNATIONAL 2017; 2017:7456853. [PMID: 28401161 PMCID: PMC5376441 DOI: 10.1155/2017/7456853] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/14/2017] [Revised: 02/18/2017] [Accepted: 02/22/2017] [Indexed: 11/17/2022]
Abstract
Background. Our previous Gräfenberg spot findings confirmed that the distal-third areas of the anterior vaginal wall bore a significantly greater number of nerves and sexual hormone may have certain degree of influence on these significant differences. However, the role of estrogen in vaginal innervations remains controversial. Methods. To investigate whether hormonal-neural interactions occur in the vagina, sixty rats were randomly divided into six groups: Sham-operated, ovariectomy, and 4 treatment groups. After 2 weeks of treatment, vaginal biopsies were prepared with hematoxylin and eosin and PGP9.5 using immunohistochemistry. Results. The density of small nerve fibers was significantly higher in the distal-half areas of intact vaginal walls than the proximal-half areas (P = 0.001). In contrast, the overall PGP 9.5-ir fiber innervation density was significantly decreased in the OVX rats subjected to surgical menopause. Sustained estrogen administration for 2 weeks resulted in nerve fiber proliferation, with values reaching normal levels in the low-dose estradiol valerate group. Conclusion. Our findings indicate that systemic hormonal therapy with low-dose estradiol valerate is effective and safe for treating deficient vaginal innervation caused by low level of estrogen activity in menopausal women and may aid studies to identify an optimal estradiol dose to provide relief from vaginal discomfort.
