BACKGROUND:  Although individualized homeopathic treatment is effective for depression in climacteric women, there is a lack of well-designed studies of its efficacy for depression in battered women or in post-traumatic stress disorder. The aim of this study was to assess the association between individualized homeopathic treatment or fluoxetine and response to depression treatment in climacteric women with high levels of domestic violence, sexual abuse or marital dissatisfaction. MATERIALS AND METHODS:  One hundred and thirty-three Mexican climacteric women with moderate-to-severe depression enrolled in the HOMDEP-MENOP Study (a randomized, placebo-controlled, double-blind, double-dummy, three-arm trial, with a 6-week follow-up study) were evaluated...

Fruit ripening is a complex physiological process involving significant external and internal modifications. Classic edible fleshy fruits have been classified as climacteric or non-climacteric according to their dependence on the hormone ethylene; however, data have increasingly confirmed the involvement of the free radical nitric oxide (NO) in this process. Moreover, the exogenous application of NO demonstrates its beneficial effects on fruit quality. This article is protected by copyright. All rights reserved...

Ethylene is instrumental to climacteric fruit ripening and EIN3 BINDING F-BOX (EBF) proteins have been assigned a central role in mediating ethylene responses by regulating EIN3/EIL degradation in Arabidopsis. However, the role and mode of action of tomato EBFs in ethylene-dependent processes like fruit ripening remains unclear. Two novel EBF genes, SlEBF3 and SlEBF4, were identified in the tomato genome and SlEBF3 displayed a ripening-associated expression pattern suggesting its potential involvement in controlling ethylene response during fruit ripening...

The avocado is a climacteric fruit and begins a softening process after harvest. During ripening, the mesocarp changes in texture, and this affects fruit quality and cold storage capacity. Softening is commonly associated with cell wall disassembly in climacteric fruits. However, changes in the cell wall structure and composition during avocado softening are poorly understood. To understand this process, cell wall pectins in "Hass" avocado fruit were studied during ripening at 20 °C after harvest and after cold storage...

Sweet cherry, a non-climacteric and highly perishable fruit, is usually cold-stored during post-harvest period to prevent senescence; therefore, metabolic profiling in response to cold storage in sweet cherry is of economic and scientific interest. In the present work, metabolic analysis was performed in fruit and stem tissues to determine the metabolic dynamics associated with cold storage in response to 1-methylcyclopropene (1-MCP), an ethylene-action inhibitor, and modified atmosphere packaging (MAP). Fruit (cv...

Background Phytoestrogens has been proposed as a replaceable medicine for climacteric hormone replacement therapy, according to EP3138562, WO/2017/019213 and US5516528. However, recent studies showed that phytoestrogens might promote the proliferation of breast cancer cells and that is associated with their estrogenic activity. Acacetin, as one phytoestrogen, has been reported to exhibit estrogenic activity. But the effects of Acacetin on breast cancer cells proliferation have not been explored Objective In this study, we evaluated the effects of acacetin on breast cancer MCF-7 cells proliferation and explored its possible mechanism...

OBJECTIVE: The Menopause Rating Scale (MRS) is one of the most frequently used instruments to evaluate menopausal symptoms; however, no cut-off score is given that would indicate the need for treatment. Our goal was to determine such a cut-off score on the MRS, using as a standard a woman's own perception of her need for treatment in relation to the severity of her symptoms. MATERIAL AND METHODS: The sample comprised 427 healthy women aged 40-59 years who were not taking hormonal treatment...

Physical and psychological changes during menopausal transition may affect various aspects of everyday functioning including women's work ability and work productivity. Presence of menopausal symptoms has been well-acknowledged to negatively affect quality of life (QOL). However, data on factors associated with occupational QOL among women at this period of life are lacking. The authors' purpose in this study was to evaluate factors affecting occupational QOL in a sample of employed mid-life women who are experiencing menopause...

Banana flour has been recognized as functional ingredient, owing to its healthy nutritional pattern. Nevertheless, unripe and ripe banana flours show different characteristics and scarce information is available about changes undergone during banana ripening. This study evaluates the changes on physiochemical (chemical composition, hydration properties, rheological properties and structural characteristic) and nutritional (resistant starch content, phenolic compound and antioxidant activity) characteristics of banana flour at the initial four ripening stages...

Nitric oxide (NO) is involved many physiological plant processes, including germination, growth and development of roots, flower setting and development, senescence, and fruit ripening. In the latter physiological process, NO has been reported to play an opposite role to ethylene. Thus, treatment of fruits with NO may lead to delay ripening independently of whether they are climacteric or nonclimacteric. In many cases different methods have been reported to apply NO to plant systems involving sodium nitroprusside, NONOates, DETANO, or GSNO to investigate physiological and molecular consequences...

Previous studies have shown that estradiol reduces reactive gliosis after a stab wound injury in the cerebral cortex. Since the therapeutic use of estradiol is limited by its peripheral hormonal effects, it is of interest to determine whether synthetic estrogenic compounds with tissue-specific actions regulate reactive gliosis. Tibolone is a synthetic steroid that is widely used for the treatment of climacteric symptoms and/or the prevention of osteoporosis. In this study, we have assessed the effect of tibolone on reactive gliosis in the cerebral cortex after a stab wound brain injury in ovariectomized adult female mice...

The fruit of Chinese jujube (Ziziphus jujuba Mill.) is immensely popular worldwide, while its fleshy fruit has a very short shelf life and suffers serious postharvest damage. The fruit has been controversially classified as non-climacteric, though the mechanisms underlying its ripening behavior, particularly the role of ethylene, have remained unclear. In this study, low and stable ethylene production was detected during ripening of Z. jujuba 'Dongzao' fruit, with production increasing at the full maturity stage...
