Albumin, the most abundant protein, contributes significantly to various physiological processes, indicating its multifunctional properties. It has drawn the attention of scientists and physicians because of its primary role in maintaining osmotic pressure and involvement in transporting numerous small molecules, including hormones, fatty acids, and drugs. A growing body of evidence has recently illustrated an additional aspect of albumin's antioxidant properties.

Although previous studies have demonstrated that royal jelly (RJ) may have estrogenic properties and prevent postmenopausal bone loss, the underlying mechanisms are not fully understood. This animal study aimed to investigate the effects of specific fatty acids of RJ, 10-hydroxy-2-decenoic acid (10H2DA) and 10-hydroxydecanoic acid (10HDAA), in ovariectomized rats. Ten-week-old female Wistar rats were divided into the Baseline, Sham, Ovx, Ovx + 10H2DA, and Ovx + 10HDAA groups.

The glomerular endothelial glycocalyx, basement membrane, podocytes, and tubules are permeability barriers against albumin excretion. This study aimed to assess the relationship between urinary albumin leakage and injuries of the glomerular endothelial glycocalyx, podocytes, and tubules in patients with PE.

The aim of this study was to elucidate the effects of endogenous estrogen on oxidative stress in women. Thus, we performed a non-interventional observational study of healthy postmenopausal ( = 71) and premenopausal ( = 72) female volunteers.
View Article and Find Full Text PDFAccording to the 2004 Japanese definition, early-onset (EO) preeclampsia (PE) is defined as PE occurring at <32 weeks of gestation. This was based on the presence of "dual peaks" (30-31 and 34-35 weeks) in the prevalence of severe forms of hypertension. In contrast, the international definition adopted a cutoff of 34 weeks based on the consensus.

Objective: This study aimed to verify whether the severity classification of preeclamptic women differed by the presence or absence of proteinuria exceeding 2.0 g/24 h.
Methods: In this retrospective cohort study, data were collected from women with singleton pregnancies who presented with preeclampsia and proteinuria at Aichi Medical University Hospital between April 1, 2008 and September 30, 2021.
Serum albumin levels are inversely related with oxidative stress, but positively related with endothelial function, in pregnant women. However, it is unclear whether hypoalbuminemia in pregnant women with preeclampsia (PE) increases the production of oxygen-derived free radicals and impacts endothelial function. The present study aimed to assess the relationship between serum albumin, oxidative stress, and endothelial dysfunction in pregnant women with PE.

Vascular endothelial cells are covered with glycocalyx comprising heparan sulfate, hyaluronan, chondroitin sulfate, and associated proteins. Glomerular endothelial glycocalyx is involved in protecting against induction of proteinuria and structural damage, but the specific components in glycocalyx that represent therapeutic targets remain unclear. Anti-vascular endothelial growth factor (VEGF) therapy is associated with an increased risk of glomerular endothelial injury.

We investigated the effects of androgenic properties of progestins combined with ethinyl estradiol (EE) on endothelial function, lipids and free radical production in such women.

Purpose: This study aimed to investigate quality of life (QOL) and psychological distress based on patient-reported outcomes (PROs) after surgery among patients with gynecological diseases in Japan.
Methods: We recruited 100 women from patients who underwent gynecological surgery followed by regimens standard for each disease. Subjects completed a questionnaire relating to life interferences, the Hospital Anxiety and Depression Scale (HADS) and the EuroQol 5 Dimension (EQ-5D) questionnaire.

This study aimed to investigate the etiology and pathology of preeclampsia (PE), a two-stage disorder involving uteroplacental dysfunction resulting from abnormal implantation and placentation, and gestational hypertension (GH), for which maternal organic vascular disorder is often an underlying factor. We assessed concentrations of oxygen free radicals (d-ROMs), maternal angiogenic factor (PlGF), and antiangiogenic factor (sFlt-1), placental hypoxic changes, oxidative DNA damage, and maternal organic vascular disorders in 23 women with PE (PE group), 13 with GH (GH group), and 16 with uncomplicated pregnancies (normal group). Intima-media thickness (IMT) of the carotid artery was assessed as a proxy for maternal organ vascular disorder.

Aim: Risk factors for cisplatin-induced nephrotoxicity (CIN) vary by population. This study aimed to assess risk factors for CIN in patients with gynecological cancer.
Methods: Patients who underwent cisplatin-based chemotherapy for gynecological cancer between January 2009 and December 2015 at Aichi Medical University School of Medicine were included in this study.
Aims: The present study to address one of the mechanisms in preeclampsia, examined whether levels of oxidative stress, human serum albumin, and endothelial function correlate in pregnant women and whether human serum albumin reduces levels of superoxide produced by NADPH oxidase activation in the human vascular smooth muscle cells.
Materials And Methods: Pregnant women with (Preeclampsia group, n = 33) and without preeclampsia (Normal group, n = 37) were recruited to determine levels of reactive oxygen species (serum diacron-reactive oxygen metabolite [d-ROM]), and the flow-mediated dilation (FMD). Human coronary arterial smooth muscle cells or omental arteries were subjected to evaluate isometric force recordings, levels of superoxide, western immunoblotting, and immunohistochemistry.
Young coconut ( Linn.) juice (YCJ) has traditionally been consumed to alleviate symptoms associated with the menopause. Recently, the authors demonstrated that short-term (6-week) YCJ supplementation to ovariectomized rats resulted in increased bone mass and bone formation parameter, suggesting that YCJ consumption has a positive effect on bone metabolism and may represent an intervention to help slow the bone loss during menopause transition.

Objective: The purpose of this study was to investigate the relationship between placental oxidative stress and maternal endothelial function in pregnant women with normotensive fetal growth restriction (FGR).
Methods: We examined serum concentrations of oxygen free radicals (d-ROMs), maternal angiogenic factor (PlGF), and sFlt-1, placental oxidative DNA damage, and maternal endothelial function in 17 women with early-onset preeclampsia (PE), 18 with late-onset PE, 14 with normotensive FGR, and 21 controls. Flow-mediated vasodilation (FMD) was assessed as a marker of maternal endothelial function.
Hypomagnesemia is one side effect in patients receiving cisplatin. However, there are few reports of cisplatin-induced hypomagnesemia in Japan. We retrospectively investigated the incidence of hypomagnesemia and nephrotoxicity in patients undergoing radiation therapy who were treated with cisplatin alone (dosage: 40 mg/m, administration interval: 1 week) for cervical cancer.

The potential routes for metastasis to the female genital tract from gastric cancer include hematogenous spread, lymphatic spread and surface implantation. The rate of lymphatic metastasis to the ovary from gastric cancer has been reported to be higher compared with that from colorectal cancer.

We recently identified SH3P2 as a negative regulator of cell motility whose function is inhibited by p90 ribosomal S6 kinase (RSK)-mediated phosphorylation downstream of ERK. We here show that myosin 1E (Myo1E) is a binding partner of SH3P2 and that the interaction of the two proteins in the cytosol prevents the localization of Myo1E to the plasma membrane.

Background: Meigs syndrome is a rare complication associated with ovarian fibromas. Although ovarian fibromas are rare in children, they are common in women with Gorlin syndrome after puberty.
Case: A 14-year-old girl with Gorlin syndrome was admitted to our hospital for ablation of basal cell carcinoma.
Aim: We aimed to assess whether the efficacy of pre-hydration with 15 mEq magnesium prevents cisplatin-induced nephrotoxicity in cisplatin regimens (dosage: 50 mg/m(2)or more) for gynecological cancer.
Patients And Methods: This historical, prospective cohort study compared nephrotoxicity in patients who received pre-hydration with or without magnesium sulfate (Mg-hydration group, n=37; non-Mg-hydration group, n=37). We used serum creatinine (Scr), creatinine clearance (Ccr) and Risk, Injury, Failure, Loss of kidney function and End-stage kidney disease (RIFLE) criteria.
