The effects of exercise on sleep have been explored from various perspectives, but little is known about how the effects of acute exercise on sleep are produced through physiological functions. We used a protocol of multiple daytime sessions of moderate-intensity aerobic exercise and examined the subsequent effects on sleep structure, core body temperature (CBT), distal-proximal skin temperature gradient (DPG), and subjective parameters. Fourteen healthy men who did not exercise regularly were evaluated under the baseline (no exercise) and exercise conditions on a within-subject crossover basis.

Despite this obvious role, the use of HRT has stagnated in Japan as well as the United States, since the interim report of the HRT trial of Women's Health Initiative study was published in 2002. The Japan Society of Obstetrics and Gynecology and Japan Society for Menopause and Women's Health formulated the Guidelines for Hormone Replacement Therapy in 2009, which was subsequently revised in 2012, with the aim of organizing perceptions about HRT and allowing people to provide or receive HRT with a sense of security.

Case Presentation: We performed uterine cervical dilation surgery in two patients with severe stenosis, followed by insertion of the levonorgestrel-releasing intrauterine system, which is used for dysmenorrhea or endometriosis-related pain because of its strong progesterone activity. Patient 1 was a 34-year-old Japanese woman who was diagnosed with dysmenorrhea caused by recurrent uterine cervical stenosis and hematometra after laser conization.
Objectives: This study investigated the effect of a brief, simple, home-based yoga program on body pain and health status in child-care workers.
Design: This was a randomized, controlled trial comparing a home-based yoga group and a control group.
Participants: The trial comprised 98 healthy female nursery school and kindergarten teachers.

Introduction: The effect of regular gum chewing on psychological status is unknown. The purpose of this study was to examine the effect of gum chewing for fourteen days on psychological status and physical and mental fatigue in healthy young adults.
Methods: We assigned 50 volunteers randomly to an intervention group (n = 26) and a control group (n = 24).
We aimed to clarify which steroid receptor is involved in the inhibitory effect of medroxyprogesterone acetate (MPA) on estrogen-induced endothelial nitric oxide synthase (eNOS) phosphorylation in human umbilical vein endothelial cells (HUVEC). The progesterone/glucocorticoid receptor (GR) antagonist RU-486 and introduction of GR siRNA caused attenuation of the inhibitory effect of MPA on the estrogen-induced eNOS phosphorylation and eNOS activity in HUVEC.

Recently, a novel assay system for TRACP-5b called the fragments absorbed immunocapture enzymatic assay (FAICEA) has been developed. With two unique monoclonal antibodies, one that is highly specific for TRACP-5b and another which absorbs inactive TRACP-5b fragments that interfere with measuring active TRACP-5b, this assay provides correct measurement of TRACP-5b activity in the serum without interference by the inactive fragments of TRACP-5b and other isotypes of TRACP, especially TRACP-5a.

There are, however, few reports on the efficacy of SSRIs for the treatment of natural postmenopausal climacteric symptoms. In this pilot study, we evaluate the SSRI, fluvoxamine, for controlling climacteric symptoms and vasomotor symptoms, in particular.

View Article and Find Full Text PDFBackground: Osteoclastic activity is mainly assessed by measuring urinary markers. To correct for differences in renal clearance, the levels of urinary markers are usually corrected by the urine creatinine concentration. Therefore, alternative serum markers to evaluate osteoclastic activity are required.
View Article and Find Full Text PDFTartrate-resistant acid phosphatase (TRACP) is a well-known marker for bone resorption, but it is not enough for clinical use in specificity of bone and instability in serum. Tartrate-resistant acid phosphatase type 5b (TRACP-5b) is an osteoclast-produced enzyme and was reported the clinical performance of a novel fragments absorbed immunocapture enzyme assay. TRACP-5b have smaller day-to-day and diurnal variation than those of urinary bone resorption markers and show the usefulness as promising markers in monitoring the treatment for osteoporosis.

The hormone replacement therapy (HRT) group received a low dose of conjugated estrogen (CEE) at a dose of 0.31 mg/day +/- medroxyprogesterone acetate (MPA) 2.

The ERN amplitude reflects attentional resource allocated to error detection. The present study examined whether discrete or gradational allocation strategy of attentional resource in error detection using the ERN amplitude.

Although MPA had no effect on basal NO production or basal eNOS phosphorylation or activity, it attenuated the E2-induced NO production and eNOS phosphorylation and activity. Moreover, we examined the mechanism by which MPA attenuated the E2-induced NO production and eNOS phosphorylation.
