background: considering the physical, emotional and psychological complications of early or delayed menopause on women`s life, it is necessary to determine associated factors of menopause age. this study designed to determine menopausal age and associated factors in women of gorgan, i.e. the capital of golestan province in the north-east of iran.   methods: in this cross-sectional study, 804 me...

Cantaloupe melons have a typical climacteric behaviour with ethylene playing a major role in the regulation of the ripening process and affecting the ripening rate. Crossing of Cantaloupe Charentais melon with a non-climacteric melon indicated that the climacteric character is genetically dominant and conferred by two duplicated loci only. However, other experiments made by crossing two non-cli...

Fruits can be divided into two groups according to the regulatory mechanisms underlying their ripening process. Climacteric fruit, such as tomato, apple, pear, and melon are characterized by a ripening-associated increase in respiration and in ethylene production, the phytohormone ethylene being the major trigger and coordinator of the ripening process. By contrast, nonclimacteric fruits, such ...

Time is a vehicle that can be used to represent aging-related processes and to index the amount of aging-related resources or burdens individuals have accumulated. Using data on cognitive (memory) performance from two Swedish studies of the elderly (OCTO and OCTO-TWIN), we illustrate how time-as-process and time-as-resources/burdens time metrics can be articulated and incorporated within a grow...

Life changes have been associated with illness onset. The Social Readjustment Rating Scale (SRRS) records numerical perceptions of the meaning of life events while the Schedule of Recent Experience (SRE) records the frequency of occurrence of life events. Data on these two instruments from 19 studies done in this laboratory have been surveyed and analyzed. They reveal significant variability am...

Japanese plums are classified as climacteric; however, some economically important cultivars selected in California produce very little ethylene and require long ripening both "on" and "off" the tree to reach eating-ripe firmness. To unravel the ripening behavior of different Japanese plum cultivars, ripening was examined in the absence (air) or in the presence of ethylene or propylene (an ethy...

During ripening fruits undergo several physiological and biochemical modifications that influence quality-related properties, such as texture, color, aroma and taste. We studied the differences in ethylene and sugar metabolism between two genetically related Japanese plum cultivars with contrasting ripening behaviors. 'Santa Rosa' (SR) behaved as a typical climacteric fruit, while the bud sport...

menopause is one of the most critical periods of woman's life. with reducing of ovarian estrogen; women are more prone to psychological and physical symptoms. the present study aimed to investigate the effect of melatonin on the climacteric symptoms.the present double blind, placebo randomized controlled clinical trial was conducted on 240 menopausal women (40 - 60 years old) referring to the g...

Mitochondria were isolated from ;Fuerte' avocado fruit (Persea americana Mill.) at four different stages of the respiratory climacteric. Preclimacteric fruit had the highest rate of succinate oxidation and the postclimacteric mitochondria the lowest. Subsequently, successive additions of ADP increased the respiratory control ratio.Arrhenius plots of succinate oxidation of intact mitochondria fr...
