    Background Climacteric fruit exhibit high ethylene and respiration levels during ripening but these levels are limited in non-climacteric fruit. Even though capsicum is in the same family as the well-characterised climacteric tomato (Solanaceae), it is non-climacteric and does not ripen normally in response to ethylene or if harvested when mature green. However, ripening progresses normally in capsicum fruit when they are harvested during or after what is called the ‘Breaker stage’. Whether e...

    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 mutant 'Sweet Miriam' (SM) displayed a non-climacteric ripening pattern. SM fruit displayed a delayed ripening that lasted 120 days longer than that of the climacteric fruit. At the full-ripe stage, both cultivars reached similar final size and weight but the non-climacteric fruits were firmer than the climacteric fruits. Fully ripe non-climacteric plum fruits, showed an accumulation of sorbitol that was 2.5 times higher than that of climacteric fruits, and the increase in sorbitol were also paralleled to an increase in sucrose catabolism. These changes were highly correlated with decreased activity and expression of NAD(+)-dependent sorbitol dehydrogenase and sorbitol oxidase and increased sorbitol-6-phosphate dehydrogenase activity, suggesting an enhanced sorbitol synthesis in non-climacteric fruits.

    Full Text Available Background: In Western countries hormone replacement therapy (HT is widely used in the treatment of climacteric women who are affected with hot flashes and night sweats. Besides, long-term HT was frequently used to manage the higher risks for osteoporosis and heart attack in postmenopause. Estrogens alone or combined with progestin feature most frequently in HT. Objectives: This HTA report addresses the questions on medical efficacy and cost-effectiveness of HT as a treatment of hot flashes and night sweats as well as in the primary prevention of osteoporosis and cardiovascular disease in postmenopause in general healthy women. Methods: The literature search for articles published after 1998 was conducted in March 2004 in standard medical and economic databases. The analysis included randomised controlled trials, systematic reviews, meta-analysis and economic evaluations considering relevant clinical endpoints in English or German language. The quality of the studies was assessed using checklists corresponding to the study type. Results: HT is highly effective in treating hot flashes in climacteric women. The question of economical efficiency cannot be answered due to the scarce database. As the positive effects (lower risk for fractures and endometrial cancer do not outweigh the negative effects (higher risk for breast cancer and general cardiovascular risk estrogen-progestin combination HT cannot be recommended for primary prevention of osteoporosis and cardiovascular disease in postmenopausal women. Discussion: The observation period of most of the studies regarding therapy of hot flashes and night sweats were too short to evaluate possible risks of long-term HT. The economic publications assessing HT for this indication varied vastly in terms of applied methods and were not carried out with respect to the German health care system. Conclusions: HT can be recommended in the short-term treatment of hot flashes and night sweats in climacteric

The purpose of the present study was to assess the symmetric involvement of the cheeks in this stage of the aging process.Methods: Skin viscoelasticity was compared on both cheeks in premenopausal and post-menopausal women with indoor occupational activities somewhat limiting the influence of chronic sun exposure. Eighty-four healthy women comprising 36 premenopausal women and 48 early post-menopausal women off hormone replacement therapy were enrolled in two groups. The tensile characteristics of both cheeks were tested and compared in each group. A computerized suction device equipped with a 2 mm diameter hollow probe was used to derive viscoelasticity parameters during a five-cycle procedure of 2 seconds each. Skin unfolding, intrinsic distensibility, biological elasticity, and creep extension were measured.Results: Both biological elasticity and creep extension were asymmetric on the cheeks of the post-menopausal women. In contrast, these differences were more discrete in the premenopausal women.Conclusion: Facial skin viscoelasticity appeared to be asymmetric following menopause. The possibility of asymmetry should be taken into account in future studies of the effects of hormone replacement therapy and any antiaging procedure on the face in menopausal women.Keywords: climacteric aging, biomechanics, photoaging, skin unfolding, biological elasticity, skin tensile properties

    Fruit ripening is a complex and highly coordinated developmental process involving the expression of many ripening-related genes under the control of a network of signalling pathways. The hormonal control of climacteric fruit ripening, especially ethylene perception and signalling transduction in tomato has been well characterized. Additionally, great strides have been made in understanding some of the major regulatory switches (transcription factors such as RIPENING-INHIBITOR and other transcriptional regulators such as COLOURLESS NON-RIPENING, TOMATO AGAMOUS-LIKE1 and ETHYLENE RESPONSE FACTORs), that are involved in tomato fruit ripening. In contrast, the regulatory network related to non-climacteric fruit ripening remains poorly understood. However, some of the most recent breakthrough research data have provided several lines of evidences for abscisic acid- and sucrose-mediated ripening of strawberry, a non-climacteric fruit model. In this review, we discuss the most recent research findings concerning the hormonal regulation of fleshy fruit ripening and their cross-talk and the future challenges taking tomato as a climacteric fruit model and strawberry as a non-climacteric fruit model. We also highlight the possible contribution of epigenetic changes including the role of plant microRNAs, which is opening new avenues and great possibilities in the fields of fruit-ripening research and postharvest biology.

    Full Text Available ABSTRACT: Every woman who lives beyond 50 years goes through a period of transition from reproductive to non-reproductive stages of life. Meno pause is considered as a clinical marker of declining ovarian function. The common climacteric symptoms experienced by women during this period can be group into: vasomotor, somatic, psy chological and sexual complaints. The aim of the study was to compare the climacteric symptoms among rural women who attained menopause and those who did not attaine d menopause in the age group of 43-55 years. METHODS AND MATERIALS: A cross-sectional study design was conducted in a r ural area in Kerala. Data were collected from 320 women by interviewing with the help of a structured questionnaire consisting of a socio-demo graphic data, and the Greene’s Climacteric Scale. The Statistical Package for the Social Scien ces software Version 16.0 was used for statistical analyses. Mann Whitney U test was used to compare the total score of climacteric symptoms and each sub-scale symptom scores (psycholo gical, somatic, and sexual scores among women who attained and not attained menopause. The X² test was applied to compare the proportion of the different grades of symptoms bet ween the different menopausal statuses.

    The menopause is universal, but what about the climacteric? In an attempt to answer this question, a study was conducted in seven south-east Asian countries, namely, Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore and Taiwan. Samples of approximately 400 women in each country were questioned about a number of climacteric complaints, incontinence and dyspareunia, consultation of a physician, menopausal status and several background characteristics. Special care was taken to overcome linguistic and cultural problems, and the data collected were kept as objective as possible. From the results obtained we were able to show that the climacteric was indeed experienced in south-east Asian countries, although in a mild form. The prevalence of hot flushes and of sweating was lower than in western countries, but was nevertheless not negligible. The percentages of women who reported the more psychological types of complaint were similar to those in western countries. The occurrence of climacteric complaints affected perceived health status. A physician was consulted for climacteric complaints by 20% of the respondents, although this was most frequently associated with the occurrence of psychological complaints and less so with that of hot flushes and sweating. The median age at menopause (51.09) appeared to be within the ranges observed in western countries. Ethnic background and age at menarche were found to have a significant influence on age at menopause. The study clearly demonstrated that climacteric complaints occur in south-east Asia. The findings suggest, however, that vasomotor-complaint-related distress might be 'translated' into psychological complaints, which are more frequently considered to warrant consulting a physician.

  10. Involvement of wound and climacteric ethylene in ripening avocado discs.

    1991-10-01

    Avocado (Persea americana Mill. cv Hass) discs (3 mm thick) ripened in approximately 72 hours when maintained in a flow of moist air and resembled ripe fruit in texture and taste. Ethylene evolution by discs of early and midseason fruit was characterized by two distinct components, viz. wound ethylene, peaking at approximately 18 hours, and climacteric ethylene, rising to a peak at approximately 72 hours. A commensurate respiratory stimulation accompanied each ethylene peak. Aminoethoxyvinyl glycine (AVG) given consecutively, at once and at 24 hours following disc preparation, prevented wound and climacteric respiration peaks, virtually all ethylene production, and ripening. When AVG was administered for the first 24 hours only, respiratory stimulation and softening (ripening) were retarded by at least a day. When AVG was added solely after the first 24 hours, ripening proceeded as in untreated discs, although climacteric ethylene and respiration were diminished. Propylene given together with AVG led to ripening under all circumstances. 2,5-Norbornadiene given continuously stimulated wound ethylene production, and it inhibited climacteric ethylene evolution, the augmentation of ethylene-forming enzyme activity normally associated with climacteric ethylene, and ripening. 2,5-Norbornadiene given at 24 hours fully inhibited ripening. When intact fruit were pulsed with ethylene for 24 hours before discs were prepared therefrom, the respiration rate, ethylene-forming enzyme activity buildup, and rate of ethylene production were all subsequently enhanced. The evidence suggests that ethylene is involved in all phases of disc ripening. In this view, wound ethylene in discs accelerates events that normally take place over an extended period throughout the lag phase in intact fruit, and climacteric ethylene serves the same ripening function in discs and intact fruit alike.

    Full Text Available Observation of climacteric-like behavior in citrus leaves depends on the detection of ethylene. However, such detection requires a gas chromatographer and complex sample preparation procedures. In this work, fluorescence spectroscopy was investigated as a diagnostic technique for climacteric-like behavior in citrus leaves. Our results indicate that the chlorophyll fluorescence presents a time evolution consistent with the ethylene evolution. Therefore, fluorescence spectroscopy may be used to observe the climacteric-like behavior in citrus leaves.

    Full Text Available MADS-box genes have been reported to play a major role in the molecular circuit of developmental regulation. Especially, SEPALLATA (SEP group genes play a central role in the developmental regulation of ripening in both climacteric and non-climacteric fruits. However, the mechanisms underlying the regulation of SEP genes to non-climacteric fruits ripening are still unclear. Here a SEP gene of pepper, CaMADS-RIN, has been cloned and exhibited elevated expression at the onset of ripening of pepper. To further explore the function of CaMADS-RIN, an overexpressed construct was created and transformed into ripening inhibitor (rin mutant tomato plants. Broad ripening phenotypes were observed in CaMADS-RIN overexpressed rin fruits. The accumulation of carotenoid and expression of PDS and ZDS were enhanced in overexpressed fruits compared with rin mutant. The transcripts of cell wall metabolism genes (PG, EXP1 and TBG4 and lipoxygenase genes (TomloxB and TomloxC accumulated more abundant compared to rin mutant. Besides, both ethylene-dependent genes including ACS2, ACO1, E4 and E8 and ethylene-independent genes such as HDC and Nor were also up-regulated in transgenic fruits at different levels. Moreover, transgenic fruits showed approximately 1-3 times increase in ethylene production compared with rin mutant fruits. Yeast two-hybrid screen results indicated that CaMADS-RIN could interact with TAGL1, FUL1 and itself respectively as SlMADS-RIN did in vitro. These results suggest that CaMADS-RIN affects fruit ripening of tomato both in ethylene-dependent and ethylene-independent aspects, which will provide a set of significant data to explore the role of SEP genes in ripening of non-climacteric fruits.

    Objective:To observe the effect of Angeng Formula on climacteric syndrome in rats. Methods:The ovaries of female SD rats were removed for the establishment of menopausal syndrome rat models. After drug delivery for 30 d, serum sex hormone levels and indexes of uterus, adrenal gland and pituitary were detected. Meanwhile, the effects of drugs on the histopathology of uterus, adrenal gland and pituitary in rats were observed. Results:Angeng Formula could increase the level of estradiol (E2) in castrated rat (P<0.01) and had a tendency to increase the level of progestin (P), lower the level of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) as well as increase the indexes of the uterus and adrenal gland. Moreover, Angeng Formula could improve the pathologic condition of the uterus, adrenal gland and pituitary in castrated rats. Conclusion:Angeng Formula has a therapeutic effect on climacteric syndrome, the mechanism of which might be related with the function of regulating sex hormone.

    Melon (Cucumis melo L.) is an important horticultural crop worldwide. Ethylene regulates the ripening process and affects the ripening rate. To screen genes that are differentially expressed at the burst of ethylene climacteric in melon fruit, we performed suppression subtractive hybridization (SSH) to generate forward and reverse libraries, for which we sequenced 439 and 445 clones, respectively. Our BLAST analysis showed that the genes from the 2 libraries were involved in metabolism, signal transduction, cell structure, transcription, translation, and defense. Six genes were analyzed by qRT-PCR during the differential developmental stage of melon fruit. Our results provide new insight into the understanding of climacteric ripening of melon fruit.

    Hot flushes in climacteric age can cause noticeable discomfort to those who have them. This functional disturbance confirms the strong relationship between the gonadic steroids and the central neurotransmitters. These complex mechanisms which control reproductive functions limit our knowledge of the pathogenesis of hot flushes. The possible intervention of prostaglandins in the rising of this disturbance and their participation in dismenorrhea have raised the hypothesis that the prostaglandins may be the common denominator in the development of dysmenorrhea in fertile age women and of hot flushes in climacteric age women. Under this context, we examined a number of women in menopause to determine if they suffered with dysmenorrhea in fertile age.

    It has been generally thought that in ethylene-sensitive plants such as carnations, senescence proceeds irreversibly once the tissues have entered the climacteric phase. While pre-climacteric petal tissues have a lower sensitivity to ethylene, these tissues are converted to the climacteric phase at a critical point during flower development. In this study, it is demonstrated that the senescence process initiated by exogenous ethylene is reversible in carnation petals. Petals treated with ethylene for 12h showed sustained inrolling and senescence, while petals treated with ethylene for 10h showed inrolling followed by recovery from inrolling. Reverse transcription-PCR analysis revealed differential expression of genes involved in ethylene biosynthesis and ethylene signalling between 10h and 12h ethylene treatment. Ethylene treatment at or beyond 12h (threshold time) decreased the mRNA levels of the receptor genes (DcETR1, DcERS1, and DcERS2) and DcCTR genes, and increased the ethylene biosynthesis genes DcACS1 and DcACO1. In contrast, ethylene treatment under the threshold time caused a transient decrease in the receptor genes and DcCTR genes, and a transient increase in DcACS1 and DcACO1. Sustained DcACS1 accumulation is correlated with decreases in DcCTR genes and increase in DcEIL3 and indicates that tissues have entered the climacteric phase and that senescence proceeds irreversibly. Inhibition of ACS (1-aminocyclopropane-1-carboxylic acid synthase) prior to 12h ethylene exposure was not able to prevent reduction in transcripts of DcCTR genes, yet suppressed transcript of DcACS1 and DcACO1. This leads to the recovery from inrolling of the petals, indicating that DcACS1 may act as a signalling molecule in senescence of flowers.

    Climacteric syndrome refers to recurring symptoms such as hot flashes, chills, headache, irritability and depression. This is usually experienced by menopausal women and can be related to a hormonal reorganization in the hypothalamic-pituitary-gonadal axis. In Traditional Chinese Medicine, originating 1000s of years ago, above-mentioned symptoms can be interpreted on the basis of the philosophic diagnostic concepts, such as the imbalance of Yin and Yang, the Zang-Fu and Basic substances (e.g. Qi, Blood and Essence). These concepts postulate balance and harmonization as the principle aim of a treatment. In this context, it is not astounding that one of the most prominent ancient textbooks dating back to 500-200 BC, Huang di Neijing: The Yellow Emperor's Classic of Internal Medicine gives already first instructions for diagnosis and therapy of climacteric symptoms. For therapy, traditional Chinese medicine comprises five treatment principles: Chinese herbal medicine, TuiNa (a Chinese form of manual therapy), nutrition, activity (e.g. QiGong) and acupuncture (being the most widespread form of treatment used in Europe). This review provides an easy access to the concepts of traditional Chinese medicine particularly regarding to climacteric syndrome and also focuses on current scientific evidence. PMID:27040419

Methods: A total of 190 cases of climacteric syndrome participants were randomly divided into auricular plus body acupuncture group (treatment group, n = 96) and simple body acupuncture group (control group, n = 94). Serum sexual hormone (FSH, LH and E2) and blood lipid (TC, LDL-C, HDL-C and TG) levels were detected before and after treatment. Results: After 30sessions of treatment, the total effective rates of treatment and control groups were 82.29% and 76.02% respectively, with the former being significantly higher than the later ( P < 0.01 ). In comparison with pre-treatment of each group, serum follicle-stimulating hormone (FSH) and luterotropic hormone (LH) levels lowered significantly; serum estradiol (E2) increased remarkably ( P < 0.05 - 0.01 ); serum high-density l ipoprotein-cholesterol (HDL-C) of two groups raised significantly ( P< 0.05- 0.01 ), and Iow-density lipoprotein (LDL)-C of treatment group decreased evidently (P< 0.05). In addition, the improvement of complaints of hot flushes, sweating, paresthesia, insomnia and emotional irritability in treatment group is significantly better than that of control group. Conclusion: Auricular acupuncture combined with body acupuncture has a better therapeutic effect than that of simple body acupuncture in the treatment of climacteric syndrome.

    The authors evaluated the diagnostic effectiveness of a triple specimen technique (cyto-histologic) performed by the Perma device. The incidence of endometrial hyperplasia (according to Dallenbach-Hellweg's classification) was estimated in 254 climacteric women selected from outpatients who come spontaneously to the Menopause Clinic of the Obstetrics and Gynecology Department (Bologna University). The selection criterion was the evidence of risk factors for endometrial carcinoma, climacteric bleedings (obesity, late menopause, high blood pressure, diabetes), or endometriotropic estrogen therapy in the postmenopause. Results showed that the cyto-histologic sampling is most useful for diagnosing endometrial hyperplasia and early carcinoma (diagnostic effectiveness: 89.0-93.8%). Also, endometrial hyperplasia was found to have a significant incidence in the group we examined. This incidence was highest in women with climacteric bleedings, secondly in women using high-dose estrogens, and thirdly in women with risk factors for endometrial carcinoma. When evaluating the different kinds of endometrial hyperplasia, we never found adenomatous hyperplasia in women on estrogen therapy. Affinity between histologic and cytologic classes was around 50% in endometrial hyperplasia and 100% in early carcinoma. This emphasizes that both samplings are needed to perform an accurate diagnosis.

    Full Text Available 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 gynecology clinics of Shiraz University of Medical Sciences (January - November 2012. The participants were randomly divided into two groups through sortition. Demographic characteristics, Goldberg's general health questionnaire (GHQ, Greene Climacteric Scale and level of Follicle Stimulating Hormone (FSH were determined for both groups before the intervention. The intervention group received one 3mg melatonin tablet each night for 3 months and the control group received the placebo in the same period. Changes of climacteric symptoms and drug complications were measured 1, 2 and 3 months after the intervention.We analyzed the data of 99 postmenopausal women in the intervention group and 101 postmenopausal women in the control group. In the melatonin group, the climacteric symptoms score decreased from 35.73+11.6 to 17.09+10.22 during the 3-month study period and regardless of time, a significant difference was observed between the two groups (P<0.001. In addition, a significant difference was found between the two groups regarding various dimensions of the climacteric symptoms over time (P<0.001. No significant difference was found regarding side effects between the two groups (P= 0.135.The study findings showed that using melatonin improved the climacteric symptoms.

The hormonal replacement was given during a period of 6 months at four different cyclic doses to mimic the normal ovary secretory pattern.Design: An open, randomized, comparative, between-patient trial conducted over 6 months in 29 menopausal women with climacteric symptoms assessed with the Kupperman index at baseline and during treatments. Saliva and serum values of 17β-estradiol and progesterone were quantitated before treatment and after 3 and 6 months. Pharmacokinetic data following transdermal administration of 17β-estradiol (0.3 mg, daily and progesterone (100 mg, daily were calculated from saliva levels using high-performance liquid chromatography analysis.Results: Improvement in climacteric symptoms was reported in 93% of women evaluated before and after 3 and 6 months of treatment. Values of saliva 17β-estradiol increased after 6 months from 0.6 ± 0.3 pg/mL to 14.1 ± 3.3 pg/mL, and the values of serum 17β-estradiol increased from 3.3 ± 2.8 pg/mL to 80.6 ± 21.9 pg/mL. Of responders, 88% characterized symptom relief as complete. No adverse health-related events were attributed to the bioidentical hormone therapy. Time to maximum saliva concentrations (Tmax, in all experimental cases, was observed after 6 hours. Baseline values were reached within 24 hours, indicating a diurnal rhythm of 17β-estradiol seen in normally cyclic women over the 24-hour period, ie, its daily biological rhythm.Conclusion: Percutaneous absorption of 17β-estradiol, as well as the absorption of progesterone, was associated with relief of climacteric symptoms. The cyclical transdermal delivery of combined bioidentical hormones may be

    After preparation on self-generated Percoll gradients, avocado (Persea americana Mill, var. Fuerte and Hass) mitochondria retain a high proportion of cyanide-insensitive respiration, especially with alpha-ketoglutarate and malate as substrates. Whereas alpha-ketoglutarate oxidation remains unchanged, the rate of malate oxidation increases as ripening advances through the climacteric. An enhancement of mitochondrial malic enzyme activity, measured by the accumulation of pyruvate, closely parallels the increase of malate oxidation. The capacity for cyanide-insensitive respiration is also considerably enhanced while respiratory control decreases (from 3.3 to 1.7), leading to high state 4 rates.Both malate dehydrogenase and malic enzyme are functional in state 3, but malic enzyme appears to predominate before the addition of ADP and after its depletion. In the presence of cyanide, a membrane potential is generated when the alterntive pathway is operating. Cyanide-insensitive malate oxidation can be either coupled to the first phosphorylation site, sensitive to rotenone, or by-pass this site. In the absence of phosphate acceptor, malate oxidation is mainly carried out via malic enzyme and the alternative pathway. Experimental modification of the external mitochondrial environment in vitro (pH, NAD(+), glutamade) results in changes in malate dehydrogenase and malic enzyme activities, which also modify cyanide resistance. It appears that a functional connection exists between malic enzyme and the alternative pathway via a rotenone-insensitive NADH dehydrogenase and that this pathway is responsible, in part, for nonphosphorylating respiratory activity during the climacteric.

    Climacteric and non-climacteric fruits have traditionally been viewed as representing two distinct programmes of ripening associated with differential respiration and ethylene hormone effects. In climacteric fruits, such as tomato and banana, the ripening process is marked by increased respiration and is induced and co-ordinated by ethylene, while in non-climacteric fruits, such as strawberry and grape, it is controlled by an ethylene-independent process with little change in respiration rate. The two contrasting mechanisms, however, both lead to texture, colour, and flavour changes that probably reflect some common programmes of regulatory control. It has been shown that a SEPALLATA(SEP)4-like gene is necessary for normal ripening in tomato. It has been demonstrated here that silencing a fruit-related SEP1/2-like (FaMADS9) gene in strawberry leads to the inhibition of normal development and ripening in the petal, achene, and receptacle tissues. In addition, analysis of transcriptome profiles reveals pleiotropic effects of FaMADS9 on fruit development and ripening-related gene expression. It is concluded that SEP genes play a central role in the developmental regulation of ripening in both climacteric and non-climacteric fruits. These findings provide important information to extend the molecular control of ripening in a non-climacteric fruit beyond the limited genetic and cultural options currently available.

    Full Text Available Keishibukuryogan (KBG; Guizhi-Fuling-Wan in Chinese is one of the Kampo (Japanese traditional medicines used to treat patients with climacteric syndrome. KBG can be used by patients who cannot undergo hormone replacement therapy due to a history of breast cancer. We evaluated whether cytosine-adenine (CA repeat polymorphism of the estrogen receptor β gene can be a predictor of the beneficial effect of KBG on climacteric syndrome. We also investigated the relationship between CA repeat polymorphism, the patients’ profiles, and the therapeutic effect. We found that CA was an SS, SL, or LL genotype according to the number of repeats. We studied 39 consecutive patients with climacteric disorders who took KBG for 12 weeks. The diagnosis of climacteric disorders was made on the basis of the Kupperman index. KBG significantly improved the patients’ climacteric symptoms (i.e., vasomotor symptoms in the patients with the LL genotype and melancholia in the patients with the SL genotype. No relationship between the patients’ profiles and CA repeat polymorphism was recognized. CA repeat polymorphism could thus be a potential biomarker to predict the efficacy of KBG in climacteric syndrome, and its use will help to reduce the cost of treating this syndrome by focusing the administration of KBG on those most likely to benefit from it.

    In postmenopausal women estrogens in combination with progestins have beneficial effects on climacteric complaints and on osteoporosis but this hormone replacement therapy (HRT) bears the risk of increased mammary carcinomas and cardiovascular diseases. Phytoestrogens at low doses have little or no effects on climacteric complaints, at high doses they mimic the effects of estrogens. Therefore other plant derived substances are currently intensively investigated. Extracts of the rhizome of black cohosh (Cimicifuga racemosa=CR) did not bind to estrogen receptors and were shown to be devoid of estrogenic effects on mammary cancer cells in vitro and on mammary gland and uterine histology in ovariectomized rats. In addition in this rat model the special extract CR BNO 1055 inhibited the occurrence of hot flushes and development of osteoporosis. In postmenopausal women CR BNO 1055 reduced major climacteric complaints as effectively as conjugated estrogens and significantly more than placebo. Similar data were published for other European CR preparations whereas 2 US American preparations were ineffective. This was most likely due to the too high doses or due to the adulteration with Asian Cimicifuga preparations. In all European studies neither effects in the uterus nor in mammary glands were observed. The effective compounds in CR are most likely neurotransmitter-mimetic in nature: dopaminergic, noradrenergic, serotoninergic and GABAergic effects were demonstrated and some have been structurally identified. We conclude that CR extracts at low doses are effective to ameliorate climacteric complaints but are devoid of adverse estrogenic effects. These finding strengthens the role of CR extracts as substitutes for HRT. This article is part of a special issue entitled: Special Issue on Phytoestrogens.

    Full Text Available Past reviews on Cimicifuga racemosa (CR without differentiation between extracts, quality, and indication altogether led to inconsistent data. Therefore, for the first time, we meet the requirements of the system's logic of evidence-based phytotherapy by taking into consideration extracts, pharmaceutical quality (reflected in a regulatory status as medicinal product, and indication. A literature search for clinical studies examining CR's efficacy and safety for menopausal complaints was conducted. The results were sorted by type of extract, regulatory status, and indication. Accordingly, Oxford Levels of Evidence (LOE and Grades of Recommendation (GR were determined. CR extracts demonstrated a good to very good safety in general, on estrogen-sensitive organs and the liver. However, only registered CR medicinal products were able to prove their efficacy. Best evidence was provided by the isopropanolic CR extract (iCR: the multitude of studies including more than 11,000 patients demonstrated consistent confirmatory evidence of LOE 1b (LOE 1a for safety leading to GR A. The studies on the ethanolic extract BNO 1055 including more than 500 patients showed exploratory evidence of LOE 2b resulting in GR B.

    Objective: To compare the therapeutic effect of Compound Recipe Gengniankang (更年康,GNK) with that of hormone replacement treatment (HRT) on climacteric female rats with osteoporosis, and to investigate the roles of estrogen and estrogen receptors in the mechanism of osteoporosis. Methods: Climac-teric female rats with osteoporosis were chosen and divided into three groups (GNK group, HRT group and control group). Apoptosis of ovarian granulose cells was measured by terminal-deoxynucleotidyl transferae mediated nick end labeling (TUNEL) assay. Serum level of estrdiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH) were determined by the method of radioimmunoassay (RIA). Reverse transcriptase polymerase chain reaction (RT-PCT) technology was used to evaluate the expression of estrogen receptor (ER) in bone. Bone mineral density (BMD) was measured by double energy X-ray absorption (DEXA). Results: In the climacteric rats, BMD, serum E2, ER mRNA expression in bone decreased remarkably, and serum FSH, LH and apoptosis of ovarian granulose cells increased obviously. After treating with GNK, all the indexes were reversed except serum E2. The increase of E2 was not significant. Conclusion:GNK is effective on climacteric osteoporosis female rats. Its role is performed not by increasing serum E2 but by enhancing ER in the bone and inhibiting apoptosis of ovarian granulose cells. GNK can deter further exhaustion of ovarian function.

    Full Text Available Climacteric fruit ripening, as it occurs in many fruit crops, depends on a rapid, autocatalytic increase in ethylene production. This agriculturally important process has been studied extensively, with tomato simultaneously acting both as a model species and target crop for modification. In tomato, the ethylene biosynthetic genes ACC SYNTHASE2 (ACS2 and ACS4 are highly expressed during fruit ripening, with a combined loss of both ACS2 and ACS4 activity preventing generation of the ethylene burst necessary for fruit ripening. However, the individual roles and importance of ACS2 and ACS4 have not been determined. In this study, we examined specifically the role of ACS4 by comparing the phenotype of an acs4 mutant firstly with that of the wild-type, and secondly with two novel ripening-inhibitor (rin mutants. Ethylene production during ripening was significantly reduced in both acs4-1, and rin lines, with rin genotypes showing the weaker ethylene burst. Also i the time between anthesis and the start of fruit ripening and ii the time required to progress through ripening were significantly longer in acs4-1 than in the wild type, but shorter than in the strongest rin mutant. The delay in ripening was reflected in the lower expression of ripening-related transcripts during the mature green and light red ripening stages. Furthermore, expression of ACS2 and ACS4 was strongly dependent on a functional RIN gene, while ACS2 expression was largely independent of ACS4. Altogether, we show that ACS4 is necessary for normal progression of tomato fruit ripening and that mutation of this gene may provide a useful means for altering ripening traits.

    This study aimed to ascertain the optimal range of red clover dry extracts (RC) and dried pomegranate concentrate powder (PCP) to induce anti-climacteric effects. Thus, the dose ranges showing protective effect of mixed formulae consisting of RC and PCP were examined in ovariectomized mice. At 28 days after bilateral ovariectomy (OVX), mixed herbal compositions (RC:PCP = 1:1, 1:2, 1:4, 1:8, 2:1, 4:1, and 8:1) were administered orally, at 120 mg/kg once daily for 84 days. We evaluated that RC and PCP mixture attenuate OVX-caused obesity, hyperlipidemia, hepatic steatosis, and osteoporosis. Compared to OVX-induced control mice, body weight and abdominal fat weight in OVX-induced mice were significantly decreased, concomitantly with increase of uterus weight by RC:PCP mixture. Additionally, significant increases in serum estradiol levels were observed in all RC:PCP-treated mice. RC:PCP mixture also showed protective effect against OVX-induced hyperlipidemia, hepatic steatosis. Total body and femur mean bone mineral density (BMD), osteocalcin, bALP contents were effectively increased by RC:PCP mixture. Taken together, RC:PCP mixture (2:1, 1:1, and 4:1) has remarkable protective effects against the changes induced by OVX. In particular, RC:PCP mixture (2:1) shows the strongest effect and may be considered as a potential protective agent against climacteric symptoms. PMID:27455321

    Full Text Available O climatério é um período abrangente da vida feminina, caracterizado por alterações metabólicas e hormonais que trazem mudanças envolvendo o contexto psicossocial. Tendo como referência as alterações de sexualidade vivenciadas no climatério, este trabalho tem por objetivo refletir sobre desejo sexual, beleza e feminilidade da mulher nessa fase. A metodologia adotada consistiu em estudo bibliográfico, em livros e artigos publicados, entre 1999 e 2009. A exigência exacerbada pela beleza eterna e jovialidade é agravada no climatério, no qual o corpo feminino não tem o mesmo vigor físico pelas alterações decorrentes do envelhecimento. A mulher climatérica vive o mito da perda do desejo sexual, todavia, continua a sentir prazer, não devendo deixar de manifestar amor e sexualidade. A visão social estereotipada sobre o papel da mulher (esposa e mãe pode interferir negativamente na visão das mulheres sobre si mesmas e no seu relacionamento com as pessoas e o mundo. Nesse sentido, é importante que as mulheres tenham acesso à informação em saúde para a compreensão das mudanças do período de climatério/menopausa, contemplando e ressignificando tal fase como integrante de seus ciclos de vida e não como sinônimo de velhice, improdutividade e fim da sexualidade.The climacteric is a long period of a woman's life, characterized by metabolic and hormonal alterations that bring changes involving the psychosocial context.

    S-adenosyl-L-methionine (SAM) is the major methyl donor in cells and it is also used for the biosynthesis of polyamines and the plant hormone ethylene. During climacteric ripening of tomato (Solanum lycopersicum 'Bonaparte'), ethylene production rises considerably which makes it an ideal object to study SAM involvement. We examined in ripening fruit how a 1-MCP treatment affects SAM usage by the three major SAM-associated pathways. The 1-MCP treatment inhibited autocatalytic ethylene production but did not affect SAM levels. We also observed that 1-(malonylamino)cyclopropane-1-carboxylic acid formation during ripening is ethylene dependent. SAM decarboxylase expression was also found to be upregulated by ethylene. Nonetheless polyamine content was higher in 1-MCP-treated fruit. This leads to the conclusion that the ethylene and polyamine pathway can operate simultaneously. We also observed a higher methylation capacity in 1-MCP-treated fruit. During fruit ripening substantial methylation reactions occur which are gradually inhibited by the methylation product S-adenosyl-L-homocysteine (SAH). SAH accumulation is caused by a drop in adenosine kinase expression, which is not observed in 1-MCP-treated fruit. We can conclude that tomato fruit possesses the capability to simultaneously consume SAM during ripening to ensure a high rate of ethylene and polyamine production and transmethylation reactions. SAM usage during ripening requires a complex cellular regulation mechanism in order to control SAM levels.

    Full Text Available Extracts from Cimicifuga racemosa (CR, synonym Actaea racemosa have shown efficacy in trials in women with menopausal symptoms. Yet, dose dependency remains unclear. Therefore, 180 female outpatients with climacteric complaints were treated for 12 weeks in a randomized, double-blind, placebo-controlled, 3-armed trial (CR extract Ze 450 in 6.5 mg or 13.0 mg, or placebo. Primary outcome was the difference in menopausal symptoms (vasomotor, psychological, and somatic, assessed by the Kupperman Menopausal Index between baseline and week 12. Secondary efficacy variables were patients’ self-assessments of general quality of life (QoL, responder rates, and safety. Compared to placebo, patients receiving Ze 450 showed a significant reduction in the severity of menopausal symptoms in a dose-dependent manner from baseline to endpoint (mean absolute differences 17.0 (95% CI 14.65–19.35 score points, P<0.0001 for 13.0 mg; mean absolute differences 8.47 (95% CI 5.55–11.39 score points, P=0.0003 for 6.5 mg. QoL and responder rates corresponded with the main endpoint. Changes in menopausal symptoms and QoL were inversely correlated. Reported adverse events and clinical laboratory testing did not raise safety concerns. The CR extract Ze 450 is an effective and well-tolerated nonhormonal alternative to hormone treatment for symptom relief in menopausal women.

METHOD: This is a cross-sectional study carried out in a gynecological outpatient unit in Rio de Janeiro, Brazil, including 151 climacteric women between 40 and 65 years of age. The CES-D was used to assess depressive symptoms and a structured interview obtained sociodemographic, clinical and gynecological data. A score above 15 points on the CES-D was considered as a cut-point for depressive state. RESULTS: Mean CES-D score was 9.2 points (standard deviation = 9.0. Insomnia, sadness and despondency had the highest scores. There was no significant association between CES-D scores and the climacteric period, sociodemographic, clinical or gynecological characteristics, except for women with psychiatric symptoms, history of depression or on antidepressants (p = 0.000. In 32 women (21% who scored > 15 on the CES-D, 72% had already suffered from a depressive state. Women with no history of depressive disorder scored more frequently above 15 when they were perimenopausal. CONCLUSION: This sample of climacteric women, from a non-specialized mental or menopausal health service, had low mean scores on the CES-D, with the item insomnia being the most highly scored. History of a previous depressive episode, but not the woman's climacteric period, was a risk factor for higher scores on the CES-D. In the group of women with no history of depression, the perimenopausal women had more scores above the cut-point. This fact may suggest that the perimenopause is a period of higher susceptibility to new onset of depressive episodes.

  5. Phytoestrogens for menopausal bone loss and climacteric symptoms.

    2014-01-01

    Women have always looked for non-hormonal options to alleviate menopausal vasomotor symptoms and prevent menopausal bone loss. The use of complementary and alternative medicine for these purposes has particularly increased after the publication of the Women's Health Initiative's results suggesting that there might be more risks than benefits with hormone replacement. Phytoestrogens are plant-derived estrogens that, although less potent than estradiol, bind to the estrogen receptor and can function as estrogen agonists or antagonists. Soy isoflavones extracted from soy are the phytoestrogens most commonly used by menopausal women. Because typical Western diets are low in phytoestrogens and taking into account the general difficulty in changing dietary habits, most clinical trials in Western women have used isoflavone-fortified foods or isoflavone tablets. Although some women might experience a reduction in the frequency or severity of hot flashes, most studies point towards the lack of effectiveness of isoflavones derived from soy or red clover, even in large doses, in the prevention of hot flashes and menopausal bone loss. This article is part of a Special Issue entitled 'Phytoestrogens'. PMID:23246986

  10. [The climacteric and biomedicine: reflections from nursing and the sociology of health and illness disciplines].

    Science.gov (United States)

    Leyva-Moral, Juan Manuel

    2012-03-01

    This article critically examines the biomedical model and how it has influenced the social construction of the meaning of the menopause. This model has been criticized as reductionist since it understands people as entities made of several parts that can be studied separately. Contrarily for nursing, people are formed by several parts in direct relation with the environment and themselves. Therefore, it is not posible to understand people's reality without considering social factors. The menopause has been described in various biomedical texts as a phenomenon similar to a disease, with severe symptoms and negative connotations. However the experiences and meanings that women ascribe to this stage of their life are varied and not always negative. In order to offer appropriate care, it is important for nursing to think about the role of social interaction in constructing the meaning individuals attribute to phenomena.

  11. Effects of gamma radiation on banana 'nanica' (Musa sp., group AAA) irradiated in pre climacteric phase

    International Nuclear Information System (INIS)

    The present work verified the effect of gamma radiation on physical and chemical parameters of banana 'nanica', analyzing possible alterations on the period of conservation and the possibility of commercial irradiation aiming the exportation. The results had demonstrated that the radiations had not produced effect on pH and total acidity. However, the bananas of the 'control group' and those that had received 0,75 kGy, had presented greater maturation degree and, radiated with 0,30 kGy, had presented greater firmness. In accordance with the results of the organoleptic analysis, can be perceived that the bananas most mature, especially of the 'control group', had had greater acceptance. The bananas of treatments 0,30 and 0,60 kGy had had minors notes for presenting minor maturation stadium. Knowing that the irradiation in adequate dose and fruits of good quality brings benefits to the storage and the process of exportation, we conclude that the dose most appropriate for the control of the maturation of the 'nanica' banana is 0,30 kGy.

    Full Text Available Abstract Background Premature menopause is a major concern of younger women undergoing adjuvant therapy for breast cancer. Hormone replacement therapy is contraindicated in women with a history of breast cancer. Non-hormonal medications show a range of bothersome side-effects. There is growing evidence that cognitive behavioral therapy (CBT and physical exercise can have a positive impact on symptoms in naturally occurring menopause. The objective of this study is to investigate the efficacy of these interventions among women with breast cancer experiencing treatment-induced menopause. Methods/design In a randomized, controlled, multicenter trial, we are evaluating the effectiveness of CBT/relaxation, of physical exercise and of these two program elements combined, in reducing menopausal symptoms, improving sexual functioning, reducing emotional distress, and in improving the health-related quality of life of younger breast cancer patients who experience treatment-induced menopause. 325 breast cancer patients (aged Discussion Cognitive behavioral therapy and physical exercise are potentially useful treatments among women with breast cancer undergoing treatment-induced, premature menopause. For these patients, hormonal and non-hormonal therapies are contraindicated or have a range of bothersome side-effects. Hence, research into these interventions is needed, before dissemination and implementation in the current health care system can take place.

    Full Text Available A Doença Arterial Coronária (DAC é uma doença multifatorial e muitos dos fatores de risco para o seu desenvolvimento (ligados aos aspectos biológicos já foram estudados e devidamente mensurados em sua importância. Os determinantes sociais dessa doença, responsável pelo maior número de mortes na cidade de São Paulo, foram pouco estudados e sua importância, negligenciada. No Brasil, as pesquisas sobre o tema são ainda incipientes e a importância da DAC, em mulheres, continua sendo subestimada, mesmo quando os dados estatísticos mostram que ela vem crescendo. As mulheres, hoje, vivem mais e, portanto, têm a possibilidade de enfrentar a doença e ainda de sobreviverem muitos anos após a menopausa, trazendo esse fato um grande impacto social. Nosso objetivo, nessa pesquisa, de caráter descritivo, foi estabelecer uma relação entre o perfil socioeconômico e cultural e os indicadores de exclusão social, encontrados em mulheres após a menopausa e com DAC, em tratamento no ambulatório de Coronariopatias do Instituto Dante Pazzanese de Cardiologia. Os resultados podem nos ajudar a entender melhor a doença e as necessidades das pacientes diante das várias formas de exclusão social que vivenciam em seu cotidiano e apontar medidas mais eficazes para programas de prevenção secundária. O diálogo entre as diferentes áreas de conhecimento, como a Medicina, a História e o Serviço Social, estabelecido para a análise dos resultados, trouxe uma compreensão abrangente dos fenômenos estudados trazendo à luz aspectos da exclusão social e discriminação de gênero, vivenciados pelas pacientes até então desconhecidos e, portanto, não valorizados pela equipe multidisciplinar.Coronary Artery Disease (CAD is a multifactorial disease and many of the risk factors for its development, linked to biological aspects, have been well studied and their importance measured. On the other hand, the study of the social determinants of this disease (that is responsible for the highest number of deaths in the city of São Paulo has been neglected. This is an area of great importance and social impact especially in developing countries. Women, in particular, are living longer now, and they may face the disease and survive many years after menopause. In Brazil, research about this theme is in its early phases and the importance of CAD in women still is underestimated, even when statistical data show that it has been increasing. This descriptive research aimed to establish the relationship between the socio-economic-cultural profile and social exclusion indicators in women after menopause and with CAD in treatment at the Coronary Diseases clinic of Instituto Dante Pazzanese de Cardiologia. The results could help us to better understand the disease and the patients' needs and point out effective actions to guide secondary prevention programs. The dialog between different areas of knowledge, such as Medicine, History, and Social Work, enabled a broad understanding of the studied phenomena, bringing to light social exclusion and gender discrimination aspects experienced by the patients that, till that time, had not been known and valued by the multidisciplinary team.

    Upon initiation of ripening in avocado fruit (Persea americana Mill. cv Hass) with 10 microliters/liter ethylene, polysome prevalence and associated poly(A)(+) mRNA increase approximately 3-fold early in the respiratory climacteric and drop off to preclimacteric levels at the peak of the respiratory climacteric. The increase in poly(A)(+) mRNA on polysomes early in the respiratory climacteric constitutes a generic increase in constitutive mRNAs. New gene expression associated with ripening is minimal but evident after 10 hours of ethylene treatment and continues to increase relative to constitutive gene expression throughout the climacteric. The respiratory climacteric can be temporally separated into two phases. The first phase is associated with a general increase in protein synthesis, whereas the second phase reflects new gene expression and accumulation of corresponding proteins which may be responsible for softening and other ripening characteristics. A major new message on polysomes that arises concomitantly with the respiratory climacteric codes for an in vitro translation product of 53 kilodaltons which is immunoprecipitated by antiserum against avocado fruit cellulase.Cyanide at 500 microliters/liter fails to affect the change in polysome prevalance or new gene expression associated with the ethylene-evoked climacteric in avocado fruit. Treatment of fruit with 500 microliters/liter cyanide alone initiates a respiratory increase within 4 hours, ethylene biosynthesis within 18 hours, and new gene expression akin to that educed by ethylene within 20 hours of exposure to cyanide.

A especificidade dos anticorpos foi demonstrada pela técnica de "Western blot", a partir de extratos protéicos de maçãs e tomates em diferentes estágios de maturação. Verificou-se que o aumento da produção de etileno, quando os frutos passaram do estágio pré-climatérico para o climatérico, está diretamente correlacionada com o aumento da síntese da ACC oxidase. Em estágios de maturação mais avançados houve uma redução da produção de etileno e da atividade ACC oxidase, mas esta proteína continuava presente. Quando o "Western blot" foi realizado com tomates transgênicos, onde a produção de etileno e a síntese da ACC oxidase foram inibidos em mais de 95%, nenhuma reação imunoquímica foi detectada. O conjunto de resultados obtidos indica que os anticorpos detectam especificamente ACC oxidase.Polyclonal antibodies were prepared to characterize the enzyme ACC (1-aminocyclopropane-1-carboxilic acid oxidase from climateric fruits. The antigen was a recombinant protein obtained from an Escherichia coli K38/pGP1,2, which contained the expression vector pT7-7A4 with one ACC oxidase DNA clone inserted. Antibody specificity was demonstrated by the Western blot technique with protein extracts from apples and tomatoes in different maturation stages. It was observed that the increase in ethylene production which happened when the fruits changed from pre-climateric to climateric stage is directly correlated with an increase in ACC oxidase syntesis. In more advanced maturation stages there was a reduction in ethylene production and ACC oxidase activity, however the protein was still present. There was no immunochemical reaction in Western blot performed with transgenic tomatoes, which had a 95% reduction of etylene production and ACC oxidase syntesis. This results suggest that the antibodies detects ACC oxidase specifically.

    2011-07-01

    The aim of this work was to evaluate the effect of 1-methyl cyclopropene (1-MCP) treatment on the development of chilling injury (CI) symptoms in four plum cultivars and to determine the relationship between the climacteric behavior of the cultivar and its sensitivity to this disorder. Significant differences in ripening pattern were found between the cultivars after long-term storage. Among the climacteric cultivars, Royal Zee plums showed a higher ethylene production rate than Linda Rosa and Friar cultivars. On the other hand, the Angeleno cultivar behaved as a suppressed climacteric type. The development of translucency symptoms was higher in Royal Zee than in Linda Rosa and Friar plums, and was almost absent in the suppressed climacteric cultivar. 1-MCP treatment significantly reduced ethylene production and the percentage of fruit affected by translucency in all climacteric cultivars. This treatment also delayed the ripening of the fruit during shelf life. In contrast, 1-MCP treatment did not affect the quality of Angeleno plums. Collectively these results suggest that the development of chilling injury in plums is related to the climacteric behavior of the cultivar and demonstrated the beneficial effects of 1-MCP maintaining plum quality during storage.

  1. Respiratory Contribution of the Alternate Path during Various Stages of Ripening in Avocado and Banana Fruits.

    Theologis, A; Laties, G G

    1978-08-01

    The respiration of fresh slices of preclimacteric avocado (Persea americana Mill. var. Hass) and banana (Musa cavendishii var. Valery) fruits is stimulated by cyanide and antimycin. The respiration is sensitive to m-chlorobenzhydroxamic acid in the presence of cyanide but much less so in the presence of antimycin. In the absence of cyanide the contribution of the cyanide-resistant pathway to the coupled preclimacteric respiration is zero. In uncoupled slices, by contrast, the alternate path is engaged and utilized fully in avocado, and extensively in banana. Midclimacteric and peak climacteric slices are also cyanide-resistant and, in the presence of cyanide, sensitive to m-chlorobenzhydroxamic acid. In the absence of uncoupler there is no contribution by the alternate path in either tissue. In uncoupled midclimacteric avocado slices the alternate path is fully engaged. Midclimacteric banana slices, however, do not respond to uncouplers, and the alternate path is not engaged. Avocado and banana slices at the climacteric peak neither respond to uncouplers nor utilize the alternate path in the presence or absence of uncoupler.The maximal capacities of the cytochrome and alternate paths, V(cyt) and V(alt), respectively, have been estimated in slices from preclimacteric and climacteric avocado fruit and found to remain unchanged. The total respiratory capacity in preclimacteric and climacteric slices exceeds the respiratory rise which attends fruit ripening. In banana V(alt) decreases slightly with ripening.The aging of thin preclimacteric avocado slices in moist air results in ripening with an accompanying climacteric rise. In this case the alternate path is fully engaged at the climacteric peak, and the respiration represents the total potential respiratory capacity present in preclimacteric tissue. The respiratory climacteric in intact avocado and banana fruits is cytochrome path-mediated, whereas the respiratory climacteric of ripened thin avocado slices comprises

    International Nuclear Information System (INIS)

    Compositional changes in fruit pulp and peel during ripening of white-and pink-fleshed guava fruit types were investigated. Fruit tissue firmeness decreased progressively, in a similar manner,in both Guava types. The white and pink guavas exhibited a typical climacteric pattern of respiration, with climacteric peak at 7.6 kilogram-force (kg-f) flesh firmness in both types. Total soluble solids (TTS) and total sugars increased in pulp and peel of both guava types with decrease in flesh firmness, more increase in total sugars ,which was determined using calorimetric method, was observed after the climacteric peak. Reducing sugars and titratable acidity increased up to the climacteric peak and decreased afterwards. Total protein increased up to the full-ripe stage and then decreased. Ascorbic acid and phenolic compounds decreased continuously during ripening of the two types. The peel showed higher values of ascorbic acid and phenolic compounds compared to the pulp. The white-fleshed guavas had higher levels of TTS, total sugars, reducing sugars, titrable acidity and ascorbic acid content compared to the pink-fleshed fruits. Changes in the activities of the cell wall degrading enzymes, pectinesterase (PE), Polygalacturonase (PG) and cellulose were also studied to find out the reason for tissue softening in guava fruit during handling, transportation and storage

    Soy- or red clover- derived products containing isoflavones have been amply studied in climacteric and postmenopausal women, and confusing contradicting results have been published. The beneficial effects on climacteric complaints, cholesterol and the development of osteoporosis are marginally at best and there are no uterine and mammary safety studies. In males, however, isoflavones may protect the prostate to make them less prone to develop cancer. Cell biological and animal experimental data support this notion. Clinical data about possible beneficial effects on cholesterol or in the bone are largely missing. Hence, soy or red clover products containing the mild estrogenic isoflavones with a slightly higher affinity to the estrogen receptor of the beta in comparison to the alpha subtype may prove to have some beneficial effects in males.

    Ripening studies of nontreated and treated papaya (papaya L) are accomplished by monitoring the ethylene and CO2 emission rates of that climacteric fruit, to evaluate its shelf life. The treatments simulate the commercial Phitosanitarian process used to avoid the fly infestation. Ethylene emission was measured using a commercial CO2 laser driven photoacoustic setup and CO2, using a commercial gas analysis also based on the photothermal effect. The results show a marked change in ethylene and CO2 emission rate pattern for treated fruits when compared to the ones obtained for nontreated fruits and a displacement of the climacteric pick shown that the treatment causes a decrease of shelf life of fruit.

    Mitochondria from avocado (Persea americana Mill, var. Fuerte and Hass) can be rapidly prepared at every stage of ripening using differential centrifugation and self-generated Percoll gradients. The procedure results in improved oxidative and phosphorylative properties, especially for mitochondria isolated from preclimacteric fruits.A gradual change in the buoyant density of avocado mitochondria takes place during ripening. Climacteric and postclimacteric avocado mitochondria have the same buoyant density as other plant mitochondria (potato, cauliflower), whereas mitochondria from preclimacteric fruit have a lower density. The transition in buoyant density occurs during the climacteric rise, and two populations of intact mitochondria (p = 1.060 and p = 1.075) can be separated at this stage. Evidence indicates that the difference in mitochondrial buoyant density between preclimacteric and postclimacteric mitochondria is likely due to interactions with soluble cytosolic components.

    Ripening of climacteric fruits is associated with pronounced changes in fruit gas composition caused by a concomitant rise in respiration and ethylene production. There is a discrepancy in the literature since some authors reported that changes in fruit gas compositions differ in attached and detached fruits. This study presents for the first time an overview of pre- and post-harvest factors that lead to variations in the climacteric respiration and ethylene production, and attempts to determine their impacts on fruit composition, i.e., dry matter, total soluble solids content and acidity. The impact of growing conditions such as the fruit position in the canopy and the fruit carbon supply; fruit detachment from the tree, including the maturity stage at harvest; and storage conditions after harvest, i.e., relative humidity and temperature were considered as well as changes in fruit skin resistance to gas diffusion during fruit growth and storage. Results showed that fruit gas composition vary with all pre and post-harvest factors studied. Although all mangoes underwent a respiratory climacteric and an autocatalytic ethylene production, whatever pre and post-harvest factors studied, large differences in ethylene production, climacteric respiration and fruit quality were measured. Results suggested that the ripening capacity is not related to the fruit ability to produce great amount of ethylene. In agreement with precedent studies, this work provided several lines of evidence that gas composition of fruit is related to its water balance. Our measurements indicated that skin resistance to gas diffusion increased after the harvest and during storage. It was so suggested that the faster ripening of detached fruit may be explained in part by changes in fruit water balance and skin resistance to gas diffusion caused by fruit detachment.

    The traditional definition of climacteric and non-climacteric fruits has been put into question. A significant example of this paradox is the climacteric fig fruit. Surprisingly, ripening-related ethylene production increases following pre- or postharvest 1-methylcyclopropene (1-MCP) application in an unexpected auto-inhibitory manner. In this study, ethylene production and the expression of potential ripening-regulator, ethylene-synthesis, and signal-transduction genes are characterized in figs ripening on the tree and following preharvest 1-MCP application. Fig ripening-related gene expression was similar to that in tomato and apple during ripening on the tree, but only in the fig inflorescence-drupelet section. Because the pattern in the receptacle is different for most of the genes, the fig drupelets developed inside the syconium are proposed to function as parthenocarpic true fruit, regulating ripening processes for the whole accessory fruit. Transcription of a potential ripening regulator, FcMADS8, increased during ripening on the tree and was inhibited following 1-MCP treatment. Expression patterns of the ethylene-synthesis genes FcACS2, FcACS4, and FcACO3 could be related to the auto-inhibition reaction of ethylene production in 1-MCP-treated fruit. Along with FcMADS8 suppression, gene expression analysis revealed upregulation of FcEBF1, and downregulation of FcEIL3 and several FcERFs by 1-MCP treatment. This corresponded with the high storability of the treated fruit. One FcERF was overexpressed in the 1-MCP-treated fruit, and did not share the increasing pattern of most FcERFs in the tree-ripened fig. This demonstrates the potential of this downstream ethylene-signal-transduction component as an ethylene-synthesis regulator, responsible for the non-climacteric auto-inhibition of ethylene production in fig.

    Melon (Cucumis melo L.) is a phenotypically diverse eudicot diploid (2n = 2x = 24) has climacteric and non-climacteric morphotypes and show wide variation for fruit firmness, an important trait for transportation and shelf life. We generated 13,789 SNP markers using genotyping-by-sequencing (GBS) and anchored them to chromosomes to understand genome-wide fixation indices (Fst) between various melon morphotypes and genomewide linkage disequilibrium (LD) decay. The FST between accessions of cantalupensis and inodorus was 0.23. The FST between cantalupensis and various agrestis accessions was in a range of 0.19–0.53 and between inodorus and agrestis accessions was in a range of 0.21–0.59 indicating sporadic to wide ranging introgression. The EM (Expectation Maximization) algorithm was used for estimation of 1436 haplotypes. Average genome-wide LD decay for the melon genome was noted to be 9.27 Kb. In the current research, we focused on the genome-wide divergence underlying diverse melon horticultural groups. A high-resolution genetic map with 7153 loci was constructed. Genome-wide segregation distortion and recombination rate across various chromosomes were characterized. Melon has climacteric and non-climacteric morphotypes and wide variation for fruit firmness, a very important trait for transportation and shelf life. Various levels of QTLs were identified with high to moderate stringency and linked to fruit firmness using both genome-wide association study (GWAS) and biparental mapping. Gene annotation revealed some of the SNPs are located in β-D-xylosidase, glyoxysomal malate synthase, chloroplastic anthranilate phosphoribosyltransferase, and histidine kinase, the genes that were previously characterized for fruit ripening and softening in other crops.

    2013-12-01

    Abstract Hormone replacement therapy (HRT) has undisputable positive effects on climacteric complaints, in the bone and on body weight but also several undesired side effects. Therefore, plant-derived alternatives are currently promoted. Phytoestrogens - primarily the isoflavones genistein, daidzein and coumestrol, stemming from soy (Glycine max) or red clover (Trifolium pratense) - were suggested to have the desired but not the undesired effects of estrogens. Most recently published placebo-controlled studies question the beneficial effects. When taken at the time of puberty however, phytoestrogens appear to protect against mammary cancer later in life. Extracts from the rhizome of Cimicifuga racemosa (black cohosh) have no estrogenic effects. In a narrow dose range they have beneficial effects on climacteric complaints, which are due to several compounds with dopaminergic, noradrenergic, serotoninergic and GABAergic actions that act together in the hypothalamus. Ecdysone is produced by several plants, including spinach (Spinacia oleracea) and was very early on shown to increase muscle mass. Later it became apparent that spinach extracts containing ecdysone decreased body fat load, thereby reducing secretion of proinflammatory cytokines by visceral adipocytes and oxidative stress. This had beneficial effects on body weight and serum lipids not only in obese postmenopausal but also in premenopausal women and in men. For the above-described plant extracts, solid placebo-controlled clinical trials are available. For other plant extracts claiming beneficial effects on climacteric complaints or postmenopausal diseases, no solid data are available.

    Although the alternative oxidase (AOX) has been proposed to play a role in fruit development, the function of AOX in fruit ripening is unclear. To gain further insight into the role of AOX in tomato fruit ripening, transgenic tomato plants 35S-AOX1a and 35S-AOX-RNAi were generated. Tomato plants with reduced LeAOX levels exhibited retarded ripening; reduced carotenoids, respiration, and ethylene production; and the down-regulation of ripening-associated genes. Moreover, no apparent respiratory climacteric occurred in the AOX-reduced tomato fruit, indicating that AOX might play an important role in climacteric respiration. In contrast, the fruit that overexpressed LeAOX1a accumulated more lycopene, though they displayed a similar pattern of ripening to wild-type fruit. Ethylene application promoted fruit ripening and anticipated ethylene production and respiration, including the alternative pathway respiration. Interestingly, the transgenic plants with reduced LeAOX levels failed to ripen after 1-methylcyclopropene (1-MCP) treatment, while such inhibition was notably less effective in 35S-AOX1a fruit. These findings indicate that AOX is involved in respiratory climacteric and ethylene-mediated fruit ripening of tomato.

    Harvested fruits of three Chinese bayberry (Myrica rubra Sieb. & Zucc.) varieties, i.e. "Biqi", "Dongkui" and "Zaodamei" which were divided into three maturities (designated as "Immature", "Mature" and "Ripe") according to fruit colour, were investigated for the changes in climacteric pattern and quality at 20 degrees C. Respiration rate and ethylene production rate were underwent 3 h during 48 h storage. Our result showed that both Immature and Mature fruits underwent rises in respiration and ethylene production rate of a climacteric rise, but no such peak was observed in Ripe fruit (Fig.1 and 2). Total soluble solids (TSS) contents increased with maturity and decreased over the 48 h at 20 degrees C (Fig.3); titratable acidity (TA) decreased with the maturity and throughout 48 h storage period (Fig.4). In "Biqi" Chinese bayberry fruit, PAL activities increased in Immature and Mature fruit, but, it decreased in Ripe fruit during the storage period; the change in Cy-3-Glu with fruit ripening was consistent with PAL activities (Table 1); there was significant positive correlation between CIRG (Color Index for Red Grape) values and Cy-3-Glu content (r=0.96**). This study provides important information on the postharvest behaviour of Chinese bayberry fruit, and our result shows that it is climacteric fruit. PMID:16121014

    In contrast to climacteric fruits, in which ethylene is known to be pivotal, the regulation of ripening in non-climacteric fruits is not well understood. The strawberry is a typical example of a non-climacteric fruit, which has been used as a model system of these types of fruit. In this study, the effect of exogenous ethephon on the expression of ethylene biosynthesis and signaling genes, FaERF2 and FaACO1, was analyzed in the Fragaria ananassa cultivar Camino Real by quantitative real-time polymerase chain reaction, and the physicochemical and phytochemical characteristics of fruits were evaluated in field trials and postharvest tests. Transcript accumulation was influenced by exogenous treatment with ethephon, which affected the pattern of gene expression during different stages of growth and fruit development, with the highest expression occurring during postharvest tests. In addition, ethephon significantly influenced the phytochemical profile of sugars, anthocyanins, phenolic compounds, and vitamin C contents both in the field- and postharvest-treated fruits at different stages. These results indicate that ethylene regulates the phenylpropanoid maturation pathway in strawberry fruit. PMID:26662403

    We conducted a survey to elucidate the influence with menopause symptoms and the impact of not only smoking but also using make-up among for Japanese women, included ages above and below the menopausal generation. The subjects of this study were 335 Japanese women from 35 to 59 years of age who were examined for the first time in the specialized women's outpatient clinic of our institution from July 2010 to June 2011 for 1 year period. We used the items of the Menopause-Specific Quality of Life Questionnaire. Similarly, we analysed the scores in relation to menopausal symptoms and whether the subject smoked, whether the subject used make-up depend on women (including foundation, lip rouge, brush one's eyebrows), how frequently she used make-up. The JMP version 9.0 software program was used to statistically analyse the score data. Significant associations were observed in psychosocial (P = 0.0196), tended to be more severe in women before menopause and after climacteric. Furthermore, the frequency of using make-up were negative relations with menopause symptoms (P = 0.0251) after climacteric. Smoking had made worse for physical symptoms (P psychological symptoms. Also, physical conditions were influenced by smoking. Using make-up frequently was often seen after climacteric because of appearance changes by oestrogen dynamic decline.

    Full Text Available Mature fruit from the yellow mombin (Spondias mombin was monitored for its respiration activity. Mature green fruit from the yellow mombin was stored in closed glass chambers and the concentration of oxygen and carbon dioxide at the end of a six hour respiration period was determined. At the same interval of time, the lid of the chamber was opened for air renewal. The increase in carbon dioxide and decrease in oxygen concentration demonstrated that the fruit was climacteric. The maximum liberation of CO2 54.2 mL Kg-1 h-1 and maximum absorption of O2 49.0 mL Kg-1 h-1 occurred 186 hours after the harvest which, obviously, represented the optimum fruit quality after the senescence process started. The respiratory quotient of fruit at a climacteric maximum was 1.11 representing the oxidation of carbohydrates. Total soluble solids increased from 9.1 °Brix (initial to 13.7 °Brix (climacteric maximum during maturation, while the total number of acids in the fruit decreased during maturation i.e. from 1.55% initially to 1.40% at pre-climacteric, 1.0% at climacteric maximum and 0.8% in the post-climacteric stage. A similar behaviour was observed in the case of ascorbic acid. There was a continuous decrease in chlorophyll and a continuous increase in the carotenoid content of fruit during maturation.Cajás verde-maduros foram armazenados em recipientes de vidro fechados e a concentração de oxigênio (O2 e de dióxido de carbono (CO2 foi determinada em intervalos de 6 horas.

    Full Text Available Abstract Background The availability of genetic and genomic resources for melon has increased significantly, but functional genomics resources are still limited for this crop. TILLING is a powerful reverse genetics approach that can be utilized to generate novel mutations in candidate genes. A TILLING resource is available for cantalupensis melons, but not for inodorus melons, the other main commercial group. Results A new ethyl methanesulfonate-mutagenized (EMS melon population was generated for the first time in an andromonoecious non-climacteric inodorus Piel de Sapo genetic background. Diverse mutant phenotypes in seedlings, vines and fruits were observed, some of which were of possible commercial interest. The population was first screened for mutations in three target genes involved in disease resistance and fruit quality (Cm-PDS, Cm-eIF4E and Cm-eIFI(iso4E. The same genes were also tilled in the available monoecious and climacteric cantalupensis EMS melon population. The overall mutation density in this first Piel de Sapo TILLING platform was estimated to be 1 mutation/1.5 Mb by screening four additional genes (Cm-ACO1, Cm-NOR, Cm-DET1 and Cm-DHS. Thirty-three point mutations were found for the seven gene targets, six of which were predicted to have an impact on the function of the protein. The genotype/phenotype correlation was demonstrated for a loss-of-function mutation in the Phytoene desaturase gene, which is involved in carotenoid biosynthesis. Conclusions The TILLING approach was successful at providing new mutations in the genetic background of Piel de Sapo in most of the analyzed genes, even in genes for which natural variation is extremely low. This new resource will facilitate reverse genetics studies in non-climacteric melons, contributing materially to future genomic and breeding studies.

    Background While bio-medically, menopause could be treated as an illness, from a psychosocial and cultural perspective it could be seen as a "natural" process without requiring medication unless severe symptoms are present. Our objective is to explore the perceptions of Turkish women regarding menopause and Hormone Therapy (HT) to provide health care workers with an insight into the needs and expectations of postmenopausal women. Methods A qualitative inquiry through semi-structured, in-depth interviews was used to explore the study questions. We used a purposive sampling and included an equal number of participants who complained about the climacteric symptoms and those who visited the outpatient department for a problem other than climacteric symptoms but when asked declared that they had been experiencing climacteric symptoms. The interview questions focused on two areas; 1) knowledge, experiences, attitudes and beliefs about menopause and; 2) menopause-related experiences and ways to cope with menopause and perception of HT. Results Most of the participants defined menopause as a natural transition process that one should go through. Cleanliness, maturity, comfort of not having a period and positive changes in health behaviour were the concepts positively attributed to menopause, whereas hot flushes, getting old and difficulties in relationships were the negatives. Osteoporosis was an important concern for most of the participants. To deal with the symptoms, the non-pharmacological options were mostly favoured. Conclusion To our knowledge, this is the first qualitative study which focuses on Turkish women's menopausal experiences. Menopause was thought to be a natural process which was characterised by positive and negative features. Understanding these features and their implications in these women's lives may assist healthcare workers in helping their clients with menopause. PMID:19134179

    When early-season avocado fruit (Persea americana Mill. cv Hass) were treated with ethylene or propylene for 24 hours immediately on picking, the time to the onset of the respiratory climacteric, i.e. the lag period, remained unchanged compared with that in untreated fruit. When fruit were pulsed 24 hours after picking, on the other hand, the lag period was shortened. In both cases, however, a 24 hour ethylene or propylene pulse induced a transient increase in respiration, called the pulse-peak, unaccompanied by ethylene production (IL Eaks [1980] Am Soc Hortic Sci 105: 744-747). The pulse also caused a sharp rise in ethylene-forming enzyme activity in both cases, without any increase in the low level of 1-aminocyclopropane-1-carboxylic acid synthase activity. Thus, the shortening of the lag period by an ethylene pulse is not due to an effect of ethylene on either of the two key enzymes in ethylene biosynthesis. A comparison of two-dimensional polyacrylamide gel electrophoresis polypeptide profiles of in vitro translation products of poly(A(+)) mRNA from control and ethylene-pulsed fruit showed both up- and down-regulation in response to ethylene pulsing of a number of genes expressed during the ripening syndrome. It is proposed that the pulse-peak or its underlying events reflect an intrinsic element in the ripening process that in late-season or continuously ethylene-treated fruit may be subsumed in the overall climacteric response. A computerized system that allows continuous readout of multiple samples has established that the continued presentation of exogeneous ethylene or propylene to preclimacteric fruit elicits a dual respiration response comprising the merged pulse-peak and climacteric peak in series. The sequential removal of cores from a single fruit has proven an unsatisfactory sampling procedure inasmuch as coring induces wound ethylene, evokes a positive respiration response, and advances ripening.

    Grapevine (Vitis vinifera L.) is a non-climacteric fruit species used as table fruit, dried raisins, and for vinification (wines) and distillation (liquors). In recent years, our knowledge of the molecular basis of ripening regulation has improved. Water status, light conditions, and temperature may hasten, delay, or enhance ripening. Hormones seem to play a central role, as their concentrations change prior to and during ripening and in response to several environmental cues. The review summarizes recent data related to the molecular and hormonal control of grape berry development and ripening, with special emphasis on secondary metabolism and its response to the environment, and pinpoints some experimental limitations.

    The skin colour changes and ethylene emission rates were monitored during papaya (C. papaya L.) fruit ripening. Two groups of papaya (‘Formosa’ and ‘Solo’) were applied in this study. The total colour difference was used as measured parameter and the corresponding half time of its saturation was used as correlation parameter. A high correlation factor between the saturation half time and corresponding climacteric peak time was found. It was concluded that high ethylene emission rate in ‘Solo’ fruit promotes a quick change of the total colour difference.

    Mandarin (Citrus reticulata), a non-climacteric fruit, is an economically important fruit worldwide. The mechanism underlying senescence of non-climacteric fruit is poorly understood. In this study, a gel-based proteomic study followed by LC-ESI-MS/MS analysis was carried out to investigate the proteomic changes involved in peel senescence in harvested mandarin "Shatangju" fruit stored for 18 days. Over the course of the storage period, the fruit gradually senesced, accompanied by a decreased respiration rate and increased chlorophyll degradation and disruption of membrane integrity. Sixty-three proteins spots that showed significant differences in abundance were identified. The up-regulated proteins were mainly associated with cell wall degradation, lipid degradation, protein degradation, senescence-related transcription factors, and transcription-related proteins. In contrast, most proteins associated with ATP synthesis and scavenging of reactive oxygen species were significantly down-regulated during peel senescence. Three thioredoxin proteins and three Ca(2+) signaling-related proteins were significantly up-regulated during peel senescence. It is suggested that mandarin peel senescence is associated with energy supply efficiency, decreased antioxidant capability, and increased protein and lipid degradation. In addition, activation of Ca(2+) signaling and transcription factors might be involved in cell wall degradation and primary or secondary metabolism. PMID:27303420

  6. Structural and functional analysis of the GRAS gene family in grapevine indicates a role of GRAS proteins in the control of development and stress responses

    Full Text Available GRAS transcription factors are involved in many processes of plant growth and development (e.g. axillary shoot meristem formation, root radial patterning, nodule morphogenesis, arbuscular development as well as in plant disease resistance and abiotic stress responses. However, little information is available concerning this gene family in grapevine (Vitis vinifera L., an economically important woody crop. We performed a model curation of GRAS genes identified in the latest genome annotation leading to the identification of 52 genes. Gene models were improved and three new genes were identified that could be grapevine- or woody-plant specific. Phylogenetic analysis showed that GRAS genes could be classified into 13 groups that mapped on the 19 Vitis vinifera chromosomes. Five new subfamilies, previously not characterized in other species, were identified. Multiple sequence alignment showed typical GRAS domain in the proteins and new motifs were also described. As observed in other species, both segmental and tandem duplications contributed significantly to the expansion and evolution of the GRAS gene family in grapevine. Expression patterns across a variety of tissues and upon abiotic and biotic conditions revealed possible divergent functions of GRAS genes in grapevine development and stress responses. By comparing the information available for tomato and grapevine GRAS genes, we identified candidate genes that might constitute conserved transcriptional regulators of both climacteric and non-climacteric fruit ripening. Altogether this study provides valuable information and robust candidate genes for future functional analysis aiming at improving the quality of fleshy fruits.

    The concept of system 1 and system 2 ethylene biosynthesis during climacteric fruit ripening was initially described four decades ago. Although much is known about fruit development and climacteric ripening, little information is available about how ethylene biosynthesis is regulated during the postclimacteric phase. A targeted systems biology approach revealed a novel regulatory mechanism of ethylene biosynthesis of tomato (Solanum lycopersicum) when fruit have reached their maximal ethylene production level and which is characterized by a decline in ethylene biosynthesis. Ethylene production is shut down at the level of 1-aminocyclopropane-1-carboxylic acid oxidase. At the same time, 1-aminocyclopropane-1-carboxylic acid synthase activity increases. Analysis of the Yang cycle showed that the Yang cycle genes are regulated in a coordinated way and are highly expressed during postclimacteric ripening. Postclimacteric red tomatoes on the plant showed only a moderate regulation of 1-aminocyclopropane-1-carboxylic acid synthase and Yang cycle genes compared with the regulation in detached fruit. Treatment of red fruit with 1-methylcyclopropane and ethephon revealed that the shut-down mechanism in ethylene biosynthesis is developmentally programmed and only moderately ethylene sensitive. We propose that the termination of autocatalytic ethylene biosynthesis of system 2 in ripe fruit delays senescence and preserves the fruit until seed dispersal.

    Ethylene is the main regulator of climacteric fruit ripening, by contrast the putative role of other phytohormones in this process remains poorly understood. The present study brings auxin signaling components into the mechanism regulating tomato fruit ripening through the functional characterization of Auxin Response Factor2 (SlARF2) which encodes a downstream component of auxin signaling. Two paralogs, SlARF2A and SlARF2B, are found in the tomato genome, both displaying a marked ripening-associated expression but distinct responsiveness to ethylene and auxin. Down-regulation of either SlARF2A or SlARF2B resulted in ripening defects while simultaneous silencing of both genes led to severe ripening inhibition suggesting a functional redundancy among the two ARFs. Tomato fruits under-expressing SlARF2 produced less climacteric ethylene and exhibited a dramatic down-regulation of the key ripening regulators RIN, CNR, NOR and TAGL1. Ethylene treatment failed to reverse the non-ripening phenotype and the expression of ethylene signaling and biosynthesis genes was strongly altered in SlARF2 down-regulated fruits. Although both SlARF proteins are transcriptional repressors the data indicate they work as positive regulators of tomato fruit ripening. Altogether, the study defines SlARF2 as a new component of the regulatory network controlling the ripening process in tomato.

    Full Text Available Tomato is a climacteric fruit, which is characterized by ripening-related increase of respiration and elevated ethylene synthesis. Ethylene is the key hormone in ripening process of climacteric fruits. The objective of this research is to study the expression of three ethylene synthesis genes: LeACO1, LeACS1A, LeACS2, and a housekeeping gene LeGAPDH in ripening tomato fruit. Specific primers have been designed to amplify complementary DNA fragment of LeGAPDH (143 bp, LeACO1 (240 bp, LeACS1A (169 bp, and LeACS2 (148 bp using polymerase chain reaction. Nucleotide BLAST results of the complementary DNA fragments show high similarity with LeGAPDH (NM_001247874.1, LeACO1 (NM_001247095.1, LeACS1A(NM_001246993.1, LeACS2 (NM_001247249.1, respectively. Expression study showed that LeACO1, LeACS1A, LeACS2, and LeGAPDH genes were expressed in ripening tomato fruit. Isolation methods, reference sequences, and primers used in this study can be used in future experiments to study expression of genes responsible for ethylene synthesis using quantitative polymerase chain reaction and to design better strategy for controlling fruit ripening in agroindustry.

    Xyloglucan endotransglycosylase (XET) is thought to be involved in fruit softening throughdisassembly of xyloglucan, which is the predominant hemicellulose of cell wall. To study the relationshipbetween fruit softening and XET during banana (Musa acuminata Colla cv. Grand Nain) fruit ripening, a fulllength cDNA (1 095 bp) encoding an XET, MA-XET1, was isolated from ripening banana fruit using RT-PCRand RACE-PCR (rapid amplification of cDNA ends) methods. Sequence analysis showed that the cDNAcontains 5' untranslated region of 66 bp, 3' untranslated region of 189 bp and ORF of 840 bp, encoding apredicted polypeptide of 280 amino acids, including DE|DFEFL motif, which is a presumptive catalyticdomain conserved in XETs. DNA gel blot analysis demonstrated that MA-XET1 is encoded by a multi-copyfamily in the banana genome. RNA gel blot analysis revealed that the level of MA-XET1 transcript in thepulp was undetectable, increased and decreased slightly at the preclimacteric, climacteric and postclimactericstages, respectively. In the peel, accumulation of MA-XET1 transcript was low, increased dramatically andthen decreased rapidly, at preclimacteric, climacteric and postclimacteric stages, respectively. Treatmentof fruit with propylene, an analog of ethylene, decreased the firmness and enhanced the accumulation ofMA-XET1 transcript in the peel and pulp. These results suggest that MA-XET1 is involved in softening ofthe peel and pulp during banana fruit ripening and its expression is regulated by ethylene at transcriptionallevel.

Twenty sedentary women, nine non-menopausal (RNM and 11 menopausal (RM, performed training for 12 weeks. Meanwhile, 23 controls, 11 not menopausal (CNM and 12 menopausal (CM, remained sedentary. Blood pressure was measured before and after the training period in conditions of rest and after a session of exercise. Training promoted variations in blood pressure at rest from 116±13 to 118±10 mmHg (p=0.73 and from 128±12 mmHg to 120±11mmHg (p=0.12 in RNM and RM, respectively. CNM and CM varied from 115±11 to 116±12 mmHg (p=0.9 and from 115±14 mmHg to 116±13 mmHg (p=0.74. Blood pressure values in one acute session did not differ between groups (p>0.05. Resistance training did not improve blood pressure in women with metabolic syndrome, regardless of climacteric.

    To clarify whether climacteric-like increases in ethylene production of senescing petals are also induced in the absence of the gynoecium in cut carnation (Dianthus caryophyllus cv. Barbara) flowers, we compared ethylene production and expression of ethylene-biosynthesis genes in detached petals and in petals, which remained on flowers (attached petals). No significant difference in longevity was observed between the attached and detached petals when held in distilled water, and both showed the inward rolling typical of senescing flowers. Treatment with silver thiosulfate complex (STS), an ethylene inhibitor, similarly delayed senescence of attached and detached petals. Climacteric-like increases in ethylene production of petals and gynoecium started on the same day, with similar bursts in attached and detached petals. Transcript levels of DcACS1 and DcACO1 were very low at harvest and increased similarly during senescence in both petal groups. Removal of the gynoecium did not significantly delay wilting of attached petals. In flowers with the gynoecium removed, the petals produced most of the ethylene while production by the other floral organs was very low, suggesting that wound-induced ethylene is not the reason for the ineffectiveness of gynoecium-removal in inhibiting flower senescence. These results indicate that ethylene biosynthesis is induced in carnation petals irrespective of the gynoecium.

    Prolyl 4-hydroxylases (P4Hs) catalyze the proline hydroxylation, a major post-translational modification, of hydroxyproline-rich glycoproteins. Two carnation petal P4H cDNAs, (Dianthus caryophyllus prolyl 4-hydroxylase) DcP4H1 and DcP4H2, were identified and characterized at the gene expression and biochemical level in order to investigate their role in flower senescence. Both mRNAs showed similar patterns of expression with stable transcript abundance during senescence progression and differential tissue-specific expression with DcP4H1 and DcP4H2 strongly expressed in ovaries and stems, respectively. Recombinant DcP4H1 and DcP4H2 proteins were produced and their catalytic properties were determined. Pyridine 2,4-dicarboxylate (PDCA) was identified as a potent inhibitor of the in vitro enzyme activity of both P4Hs and used to determine whether inhibition of proline hydroxylation in petals is involved in senescence progression of cut carnation flowers. PDCA suppressed the climacteric ethylene production indicating a strong correlation between the inhibition of DcP4H1 and DcP4H2 activity in vitro by PDCA and the suppression of climacteric ethylene production in cut carnation flowers.

    GRAS transcription factors are involved in many processes of plant growth and development (e.g., axillary shoot meristem formation, root radial patterning, nodule morphogenesis, arbuscular development) as well as in plant disease resistance and abiotic stress responses. However, little information is available concerning this gene family in grapevine (Vitis vinifera L.), an economically important woody crop. We performed a model curation of GRAS genes identified in the latest genome annotation leading to the identification of 52 genes. Gene models were improved and three new genes were identified that could be grapevine- or woody-plant specific. Phylogenetic analysis showed that GRAS genes could be classified into 13 groups that mapped on the 19 V. vinifera chromosomes. Five new subfamilies, previously not characterized in other species, were identified. Multiple sequence alignment showed typical GRAS domain in the proteins and new motifs were also described. As observed in other species, both segmental and tandem duplications contributed significantly to the expansion and evolution of the GRAS gene family in grapevine. Expression patterns across a variety of tissues and upon abiotic and biotic conditions revealed possible divergent functions of GRAS genes in grapevine development and stress responses. By comparing the information available for tomato and grapevine GRAS genes, we identified candidate genes that might constitute conserved transcriptional regulators of both climacteric and non-climacteric fruit ripening. Altogether this study provides valuable information and robust candidate genes for future functional analysis aiming at improving the quality of fleshy fruits. PMID:27065316

    Endogenous ethylene production and alternative oxidase (AOX) protein expression in "Royal Gala" apple fruits were investigated after treatments with cold (0℃ for 1 week) and heat (38℃ for 1 h).A monoclonal antibody to the terminal oxidase of the alternative pathway from Sauromatum guttatum was used to identify the AOX protein in apple fruits.The molecular mass of AOX in "Royal Gala" apple fruits is approximately 38 kDa, similar to those reported in tobacco and tomato.The cold treatment depressed the release of endogenous ethylene production before the climacteric ethylene production and obviously induced the expression of AOX protein expression.The heat treatment had the opposite effects on the ethylene production and AOX protein expression.In addition, the climax of endogenous ethylene production preceded the maximum AOX expression after the cold temperature treatment.It is therefore proposed that in climacteric fruits the production of induced ethylene is not coordinated with the level of AOX protein.

    Full Text Available Taking into account that climacteric constitutes a physiological state in woman’s life, which covers a large stage of her life cycle, it is important that nursery professionals will develop an Action Plan, whose main objective will be health. Covering, then, this stage from a multidisciplinary and holistic field is going to contribute to both: the adoption of healthy life habits and the repercussions that symptoms and physiological processes associated with menopause have on women. Another objective for nurses there must be to provide all our knowledge in a detailed and focused on the individual needs that may come up way. That way, we lay the foundations for facing climacteric with the minimum deterioration of the quality of life and well being.This article is an analysis of the etiology of every one of the most prevalent menopause problems, the predisposing factors to suffer them or to make them get worse, and the habits that are going to prevent larger spill-over effects of those problems. Furthermore, a revision about how nutrition, exercise, toxic substances consumption, etc. have repercussions on musculoskeletal problems, vascular symptoms, urogenital problems, psychological alterations, and gynaecological and breast cancer is made.

  19. Growth and Respiratory Response of Fig (Ficus carica L. cv. Mission) Fruits to Ethylene.

    Growth in diameter of the fig (Ficus carica L. cv. Mission) fruit takes place in three distinct periods; two periods (I and III) of rapid growth are separated by a period (II) of slow growth. With respect to exposure to ethylene, the fruit exhibits a two phase response. Ethylene inhibits fruit growth in phase A (period I), the period of cell division, stimulates growth in early phase B (early period II), and stimulates both growth and ripening during the remainder of phase B (late period II and period III). The adverse effect of exogenous ethylene on fruits during phase A is thought to be due to inhibition of cell division. The gradual transition occurring in the response of fruits during phase B was interpreted in terms of carbohydrate level in the fruits.The onset of period III and a respiratory climacteric rise was preceded by or concomitant with a sudden burst of endogenous ethylene synthesis. This, together with the fact that exogenous ethylene applied at the proper stage of fruit growth triggers both ripening and the climacteric rise, leads to the conclusion that ethylene is the causal agent. In other words, the data support the concept that ethylene is a growth hormone that initiates a chain of metabolic and physiological events leading to fig fruit ripening.

  20. Roles of Abscisic Acid in Fruit Ripening

    Full Text Available Abscisic acid (ABA is a plant growth regulator, and it plays a variety of important roles throughout a plant’s life cycle. These roles include seed development and dormancy, plant response to environmental stresses, and fruit ripening. ABA concentration is very low in unripe fruit, but it increases as a fruit ripens, so it is therefore believed that ABA plays an important role in regulating the rate of fruit ripening. This article reviews the effect of ABA on ripening and quality of climacteric and non-climacteric fruits. The effects of ABA application on fruit ripening are subsequently discussed. Moreover, it is found that during fruit ripening, ABA also contributes to other functions, such as ethylene and respiratory metabolism, pigment and color changes, phenolic metabolism and nutritional contents, cell wall metabolism and fruit softening, and sugar and acid metabolism. These processes are all discussed as part of the relationship between ABA and fruit ripening, and the possibilities for its commercial application and use are highlighted.

    57 women were studied who were GMP patients, whose spontaneous menopause had occurred 6 to 36 months ago and who did not take any sexual hormones. Purpose of the study was to determine psychosocial influences on the time of onset of the menopause and on climacteric complaints. It was found that the overall impairment by hot flushes and pain in the limbs during this phase of life was largely independent of the studied parameters. With regard to the time of onset of the menopause there was a trend to an linear relationship between the factor "social dependence" and the age at which menopause occurred, as well as a link between that age and period intervals 5 years before cessation of menstrual bleeding. An enhanced tendency to exhaustion representing a nonspecific menopause syndrome was found particularly often in women who were highly "socially dependent". There was no relationship between climacteric complaints on the one hand and, on the other hand, experiences of loss, social stress and relief factors, partnership relations, experiences of menarche, menstruation and menopause as well as basic feeling tone; however, a depressive tone, as defined by the Giessen test, was clearly predominant in the examined population. It is concluded from these results that flushes in the early postmenopausal phase are mostly a biological phenomenon, whereas vegetative concomitant complaints are markedly dependent on psychosocial factors that correspond to a typically "feminine" role enactment as postulated by social convention.

Many women also experience bothersome vasomotor and vaginal symptoms during the menopausal transition. Results of systematic reviews and meta-analyses of randomized controlled trials have shown that both systemic estrogen therapy or hormone therapy (estrogen combined with a progestin are useful to prevent bone loss, and they are the most effective treatment for such climacteric symptoms as hot flushes, sweating, vaginal dryness, and dyspareunia. Unfortunately, estrogen therapy and hormone therapy increase the risk of endometrial and breast cancer, respectively. The selective estrogen receptor modulators (SERMs result in positive estrogenic effects on bone, with no negative effects on the endometrium and breast but do not provide relief from postmenopausal symptoms. The combination of a SERM with estrogen as a tissue selective estrogen complex (TSEC is a new strategy for the prevention of bone loss and the treatment of climacteric symptoms. This combination is particularly interesting from a clinical point of view, taking into account that estrogen alone did not increase breast cancer risk by the Women's Health Initiative. TSEC is hypothesized to provide the benefits of estrogen-alone therapy, with an improved tolerability profile because the SERM component can make possible the elimination of progestin. The objective of this review was to critically evaluate the evidence from the reports published to date on the use of bazedoxifene (a third

    Full Text Available The origin of climacteric has been subject of debate. Most opinions agree in that it arises exclusively from natural selection. In this paper the author argues that, besides this reason there is another, even more important; for him, climacteric is the final response to fatigue or the third stage of the general adaptation syndrome, just as in elderly people there is a loss of the capacity of proliferation of fibroblasts and lack of response to insulin. From a genetic point of view, this corresponds to an antagonic pleiotropy: the genetic program that has made the human adrenergic and corticotropic systems hyperactive, has also caused that they do not reach senescence intact. High concentrations of stress hormones during youth and adulthood in humans, as compared to chimpanzees, gorillas and orangutans, and the hormonal cascade reactions elicited by them are meaningfully related to our most conspicuous illnesses, our genotype/phenotype and, in the long term, with climacteric. Se ha conjeturado a menudo sobre las razones del climaterio y la mayoría de los autores sostiene que es un fenómeno que surge exclusivamente de la selección natural. Aquí asumimos que, aunque esa sea parte de la explicación, no es la razón primordial. Así como con la edad se da la pérdida, por ejemplo, de la capacidad proliferativa de los fibroblastos y de la sensibilidad a la insulina, el climaterio podría corresponder no más que a la fatiga o tercera etapa del Síndrome de Adaptación General. En un enfoque genético correspondería, pues, a una pleiotropía antagónica: el programa genético que ha hecho hiperactivos a los sistemas adrenérgico y corticotrópico del ser humano, evitaría también que llegara incólume al punto final de senescencia.

    Tomato (Lycopersicon esculentum cv. 402) was used to investigate the effects of 1-MCP (1-methylcyclopropene) treatment on ethylene production, respiration, vitamin C, chlorophyll, titratable acid,change of fruit color and rot. The results indicated that 1-MCP strongly inhibited ethylene production and respiration of tomato at very low concentration, delayed the incidence of climacteric peak of ethylene production and respiration. 1-MCP also delayed the decrease of vitamin C, chlorophyll and titratable acid during shelf life and storage significantly. Shelf and storage life of fruit treated with 1-MCP were extended at least 10 days at ambient (20 - 22℃ ) and 15 days at storage (9 - 11℃ ) temperature, respectively. Efficacy of 1-MCP on shelf and storage life was improved by increasing its concentration. After treatment of 1-MCP, rots were markedly lower than that of untreated fruit. 1-MCP treatment delayed the fruit color change.

  5. Effect of maleic hydrazide and waxing on quality and shelf life of papaya (carica papaya L.) fruits

    International Nuclear Information System (INIS)

    The effect of post harvest treatment of maleic hydrazide (MH) with and with out waxing on the quality and shelf-life of Baladi and Ekostika I papaya fruits at 18 ±1°C and 85%-90% relative humidity was evaluated. Maleic hydrazide at 250 and 500 ppm significantly delayed fruit ripening by two and three days in both papaya cultivars, respectively, compared with untreated fruits. The higher the concentration, the more was the delay in fruit ripening. The results also showed that waxing addition to MH resulted in a delay of two more days in fruit ripening that treatment with MH alone. The effect of MH and waxing treatments in delaying papaya fruits ripening was manifested in retarded respiratory climacteric, reduced weight loss and delayed fruit softening and increase in total soluble solids and ascorbic acid content.(Author)

    The menopausal transition or "perimenopause" represents a time period of turbulent changes in ovarian hormones as middle-aged women progress into menopause. The purpose of this article is to review the literature to determine the effect of the menopausal transition on migraine headaches and to develop a rational treatment approach to these patients. The menopausal transition is divided into early and stages based upon patterns of menstruation and specific reproductive hormones. Studies would suggest that the prevalence of migraine and other climacteric symptoms tend to peak during the late menopausal transition particularly in those with a past history of premenstrual stress disorder. Treatment approaches vary by stage of the menopausal transition and include conventional daily preventatives, mini-prophylaxis and hormonal therapies.

    Tomato fruit ripening is characterized by an increase in ethylene biosynthesis, a burst in respiration (i.e. the climacteric), fruit softening and pigmentation. As whole tomatoes ripened from mature green to red, there was an increase in the alternative oxidase capacity. Aging pink tomato slices for 24 and 48 hrs also showed an increase of alternative oxidase and cytochrome oxidase capacities. Monoclonal antibodies prepared to the Sauromatum guttatum alternative oxidase were used to follow the appearance of alternative oxidase in tomato fruits. There is a corresponding increase in a 36kDa protein with an increase in alternative oxidase capacity. Effects of ethylene and norbornadiene on alternative oxidase capacity were also studied. We are using an alternative oxidase cDNA clone from potato to study the expression of mRNA in ripening and wounded tomatoes to determine if the gene is transcriptionally regulated.

    The plant hormone ethylene plays a key role in climacteric fruit ripening. Studies on components of ethylene signaling have revealed a linear transduction pathway leading to the activation of ethylene response factors. However, the means by which ethylene selects the ripening-related genes and interacts with other signaling pathways to regulate the ripening process are still to be elucidated. Using tomato (Solanum lycopersicum) as a reference species, the present review aims to revisit the mechanisms by which ethylene regulates fruit ripening by taking advantage of new tools available to perform in silico studies at the genome-wide scale, leading to a global view on the expression pattern of ethylene biosynthesis and response genes throughout ripening. Overall, it provides new insights on the transcriptional network by which this hormone coordinates the ripening process and emphasizes the interplay between ethylene and ripening-associated developmental factors and the link between epigenetic regulation and ethylene during fruit ripening.

It takes 84 days (12 weeks for pequi to develop with the onset of flowering in September and early fruit set in January. Pequi fruit showed a simple sigmoid growth curve, and its growth was characterized based on fresh mass and longitudinal and transverse diameters. The contents of titratable acidity, soluble solids, β-carotene, and vitamin C increased during fruit growth, reaching their maximum values at the 12th week (84 days after anthesis. Pequi is a fruit with an extremely high respiratory activity; its respiratory rate decreased during its development. Pequi fruit has been classified as a non-climacteric fruit due to the decrease of both respiration and ethylene production rates during maturation and ripening.

    Tibolone is a synthetic steroid with estrogenic, androgenic, and progestagenic properties used for the prevention of postmenopausal osteoporosis and treatment of climacteric symptoms. Tibolone shows almost no action on breast and endometrium, which are target-organs for estrogens and progesterone activity. The aim of this work was to investigate the spatial distribution of calcium and zinc minerals in the femoral head of ovariectomized rat in order to evaluate the effects of the long-term administration of tibolone. For that purpose X-ray microfluorescence was used with synchrotron radiation imaging technique which was performed at Brazilian Light Synchrotron Laboratory, Campinas, SP. Minerals were not homogeneously distributed in trabecular bone areas; a higher concentration of calcium in the trabecular regions at femoral heads was found in ovariectomized and tibolone-treated rats compared to ovariectomized and control groups.

    The ability of nonhuman animals to project individual actions into the future is a hotly debated topic. We describe the caching behaviour of tayras ( Eira barbara) based on direct observations in the field, pictures from camera traps and radio telemetry, providing evidence that these mustelids pick and cache unripe fruit for future consumption. This is the first reported case of harvesting of unripe fruits by a nonhuman animal. Ripe fruits are readily taken by a variety of animals, and tayras might benefit by securing a food source before strong competition takes place. Unripe climacteric fruits need to be harvested when mature to ensure that they continue their ripening process, and tayras accurately choose mature stages of these fruits for caching. Tayras cache both native (sapote) and non-native (plantain) fruits that differ in morphology and developmental timeframes, showing sophisticated cognitive ability that might involve highly developed learning abilities and/or prospective thinking.

    Full Text Available The strawberry is as non-climacteric fruit, but has a high post-harvest respiration rate, which leads to a rapid deterioration at room temperature. This study aimed to evaluate the application of biodegradable coating on postharvest conservation of organic strawberries, cv. Camarosa, packed in plastic hinged boxes and stored at 10ºC. The treatments consisted of: a control; b 2% cassava starch; c 1% chitosan; and d 2% cassava starch + 1% chitosan. Physical and chemical characteristics of fruits were evaluated at 3, 6 and 9 days of storage, and microbiological and sensory analyses were carried out at the end of the storage period. The treatments influenced positively the post-harvest quality of organic strawberries. The coating cassava starch + chitosan provided the best results, with less than 6% of loss in fruit mass, lower counts of yeast and psychrophilic microorganisms and the best appearance according to the sensory analysis.

  17. Regulation of Senescence in Carnation (Dianthus caryophyllus): Effect of Abscisic Acid and Carbon Dioxide on Ethylene Production.

    Science.gov (United States)

    Mayak, S; Dilley, D R

    1976-11-01

    Abscisic acid hastened senescence of carnation flowers and this was preceded by stimulation of accelerated ethylene production. Carbon dioxide delayed the onset of autocatalytic ethylene production in flowers regardless of treatment with abscisic acid. Flowers exhibited a low and transient climacteric of ethylene production without wilting while in 4% carbon dioxide and underwent accelerated ethylene production culminating in wilting when removed from carbon dioxide. Hypobaric ventilation, which lowers ethylene to hyponormal levels within tissues, extended flower longevity and largely negated enhancement of senescence by abscisic acid. Supplementing hypobarically ventilated flowers with ethylene hastened senescence irrespective of abscisic acid treatment. Collectively, the data indicate that abscisic acid hastens senescence of carnations largely as a result of advancing the onset of autocatalytic ethylene production.

Citations were searched in the following databases: MEDLINE via PubMed, Web of Science, CENTRAL, CINAHL, and LILACS. A combination of the following keywords was used: breast neoplasm, acupuncture, acupuncture therapy, acupuncture points, placebos, sham treatment, hot flashes, hot flushes, menopause, climacteric, and vasomotor symptoms. Results: a total of 272 studies were identified, five of which were selected and analyzed. Slight superiority of traditional acupuncture compared with sham acupuncture was observed; however, there were no strong statistical associations. Conclusions: the evidence gathered was not sufficient to affirm the effectiveness of traditional acupuncture compared with sham acupuncture. PMID:27533271

    Full Text Available The objectives of this experiment was to examine the influence of polyamine, gibberelline and harvesting times to inhibit ripening process and to maintain postharvest quality on mangosteen. The method applied was randomized block design with two factors and three replications. First factor was harvesting time consisting of 14, 15 and 15 weeks after anthesis. Second factor is chemical concentration consisting of control (aquadest, GA3 (150, 200, 250 mg/l, polyamine (0,3; 1 and 3 mM. The result showed that spermidine application at 1 mM was more effective to maintain the postharvest quality of mangosteen, the fruit remained soft and the climacteric peak was longer than that of control. Gibberelline application showed unsightly result compared to control. Mangosteen fruits with harvesting time of 15 and 16 weeks after anthesis had better perfomance than those of harvesting at 14 weeks after anthesis, the fruit was remained soft and the weight lost was less.

    Postmenopausal osteoporosis affects millions of women, being estrogen deficiency the key factor in the pathogenesis of involutional osteoporosis. Fracture prevention is one of the public health priorities worldwide. Different treatments for osteoporosis are available. The various options are aimed to maintain bone health and decrease the risk of fractures. The majority of these drugs are antiresorptive agents, i.e., drugs that lower bone turnover, inhibiting osteoclastic bone resorption. Dietary sources of calcium intake and vitamin D are ideal, while pharmachological supplements should be used if diet alone cannot provide the recommended daily intake. Bisphosphonates are first-line therapy for patients with established osteoporosis at high risk of fracture. Some serious, but rare, adverse events have been associated with their long-term administration. The monoclonal antibody to RANKL, named denosumab, administered as a 60-mg subcutaneous injection every 6 months, is a valuable option for the treatment of postmenopausal osteoporosis in women at increased or high risk of fractures, who are unable to take other osteoporosis treatments. Teriparatide (PTH 1-34) is the only available osteoanabolic drugs for osteoporosis treatment at present. Its use is limited to severe osteoporosis because of the high cost of the treatment. In climacteric women, in different stages of menopausal transition, and beyond, hormone replacement therapy at different doses (HRT) rapidly normalizes turnover, preventing and/or treating osteoporosis. HRT is able to preserve and even increase BMD at all skeletal sites, leading to a significant reduction in vertebral and non-vertebral fractures. Selective estrogen modulators (SERMs) as raloxifene and bazedoxifene reduce bone turnover and maintains or increases vertebral and femoral BMDs in comparison to placebo and reduces the risk of vertebral and new vertebral fractures, in high risk women. The combination of a SERM with an estrogen has been

    Mesocarp protoplasts were isolated from mature avocado fruits (Persea americana cv. Hass) at varying stages of propylene-induced ripening. Qualitative changes in the pattern of radiolabel incorporation into polypeptides were observed in cells derived from fruit at the different stages. Many of these differences correlate with those observed during radiolabeling of polypeptides from fresh tissue slices prepared from unripe and ripe fruit. Protoplasts isolated from fruit treated with propylene for one day or more were shown to synthesize cellulase (endo-ß-1,4-glucanase) antigen, similar to the intact propylene-treated fruit. These results suggest that the isolated protoplasts retain at least some biochemical characteristics of the parent tissue. The cells may also be used in transient gene expression assays. Protoplasts isolated from preclimacteric and climacteric fruit were equally competent in expressing a chimeric test gene, composed of the CaMV 35S RNA promoter fused to the bacterial chloramphenicol acetyltransferase gene, which was introduced by electroporation.

    The ripeness degree of climacteric fruits, such as avocado ( Persea americana Mill.), can be correlated with rheological properties. However, there remains little information on not only the postharvest changes in texture of avocado fruit from different origins but also the spatial variation within fruit. In addition, the relationship between changes in texture and composition of fatty acids and major nonstructural carbohydrates (NSCs) of fruit tissue during ripening is unknown. The texture of different horizontally cut slices from individual fruits within a consignment was measured during ripening using a previously unreported technique. The composition of fatty acids and NSCs in fruit mesocarp tissue was determined. The composition of fatty acids and oil and dry matter contents varied significantly according to origin. Significant changes in texture, mannoheptulose and perseitol contents, and linoleic acid percentage were found in avocado fruit flesh during ripening. Spatial variation within fruit was detected in both textural and biochemical characteristics.

    The poly(A) (+)RNA populations from avocado fruit (Persea americana Mill cv. Hass) at four stages of ripening were isolated by two cycles of oligo-dT-cellulose chromatography and examined by invitro translation, using the rabbit reticulocyte lysate system, followed by two-dimensional gel electrophoresis (isoelectric focusing followed by sodium dodecyl sulfate polyacrylamide gel electrophoresis) of the resulting translation products. Three mRNAs increased dramatically with the climacteric rise in respiration and ethylene production. The molecular weights of the corresponding translation products from the ripening-related mRNAs are 80,000, 36,000, and 16,500. These results indicate that ripening may be linked to the expression of specific genes.

    Red Raspberry (Rubus idaeus) is traditionally classified as non-climacteric, and the role of ethylene in fruit ripening is not clear. The available information indicates that the receptacle, a modified stem that supports the drupelets, is involved in ethylene production of ripe fruits. In this study, we report receptacle-related ethylene biosynthesis during the ripening of fruits of cv. Heritage. In addition, the expression pattern of ethylene biosynthesis transcripts was evaluated during the ripening process. The major transcript levels of 1-aminocyclopropane-1-carboxylic acid synthase (RiACS1) and 1-aminocyclopropane-1-carboxylic acid oxidase (RiACO1) were concomitant with ethylene production, increased total soluble solids (TSS) and decreased titratable acidity (TA) and fruit firmness. Moreover, ethylene biosynthesis and transcript levels of RiACS1 and RiACO1 were higher in the receptacle, sustaining the receptacle's role as a source of ethylene in regulating the ripening of raspberry.

    Full Text Available Background: The aim of the study was to analyse and present the opinions of women in perimenopause on subjectively perceived symptoms characteristic of the climacteric period, and connected with their professional functioning, as well as to evaluate the effects of selected variables on the incidence and severity of these symptoms and the women’s life satisfaction. Material and Methods: The study included 250 professionally active women in perimenopausal age (40–57 years. The study used the Satisfaction with Life Scale (SWLS to evaluate life satisfaction of women and the Kupperman Index (KI as quantitative and qualitative self-assessment of climacteric symptoms. The authors also used a questionnaire of their own design that contains an index of defined symptoms of perimenopause, which warrants the use of Pareto-Lorenz analysis. Results: The obtained results prove the presence of statistically significant correlations between the occurrence and severity of menopausal symptoms and the place of enployment (p = 0.04912, gynecological care (p = 0.00325, hormone replacement therapy (HRT (p = 0.01523 and assessment of life satisfaction (p = 0.0325. Among the symptoms particularly influencing effective professional functioning, women pointed out hot flashes, irritability, reduced concentration and coordination, sleep disturbances, and increased sweating. Conclusions: There is a statistically significant correlation between the woman’s place of employment, gynecological care, HRT, the evaluation of life satisfaction and the severity of perimenopausal symptoms. A set of symptoms whose presence and severity influence the sense of life satisfaction and evaluation of professional functioning was observed. Among the most frequently reported symptoms that exert an adverse effect on professional functioning of women are: hot flushes, irritability, reduced concentration and coordination, sleep disturbances, and increased sweating.

    Hot flashes are a disorder of thermoregulation due to the lack of estrogens and are the most common and characteristic climacteric complaint. Hormone replacement therapy is the gold standard treatment but now its use is limited due to several side effects. Need therefore arises to search for non-estrogenic alternatives. It is well established that extracts of Cimicifuga racemosa (CR) ease climacteric complaints but solid animal experimental data supporting such effects are not available. The availability of sensitive transponders which record subcutaneous temperature continuously enables nowadays experiments in rats to establish whether they have hot flashes following ovariectomy (Seidlova-Wuttke et al. 2003) and if so, whether they can be influenced by the extract of CR BNO 1055. Intact Sprague-Dawley rats (n=16) were acclimatized and their subcutaneous body temperature was measured in 5 min intervals and mean values from 3h recordings were calculated. Thereafter, the rats were ovx and fed either with soy free (sf) or CR BNO 1055 (25 mg/animal/day) food. Temperature was recorded again after acute and sub-acute application of CR. In individual intact animals temperature was stable over the 3h recording period. Following ovx temperature pulses appeared with peaks occurring every 20-40 min. These fluctuations were not seen in CR BNO 1055 treated animals resulting in significantly higher mean temperatures in ovx in comparison to intact or ovx CR BNO treated rats. This reduction of hot flashes by BNO 1055 outlasted the experimental period of 3 weeks. These results suggest that the ovx rats and the new temperature-sensitive device may be useful for the study of hot flashes. Furthermore the results prove that the CR BNO 1055 exerts hot flash reducing effects.

    Full Text Available Abstract Background Fruit development, maturation and ripening consists of a complex series of biochemical and physiological changes that in climacteric fruits, including apple and tomato, are coordinated by the gaseous hormone ethylene. These changes lead to final fruit quality and understanding of the functional machinery underlying these processes is of both biological and practical importance. To date many reports have been made on the analysis of gene expression in apple. In this study we focused our investigation on the role of ethylene during apple maturation, specifically comparing transcriptomics of normal ripening with changes resulting from application of the hormone receptor competitor 1-Methylcyclopropene. Results To gain insight into the molecular process regulating ripening in apple, and to compare to tomato (model species for ripening studies, we utilized both homologous and heterologous (tomato microarray to profile transcriptome dynamics of genes involved in fruit development and ripening, emphasizing those which are ethylene regulated. The use of both types of microarrays facilitated transcriptome comparison between apple and tomato (for the later using data previously published and available at the TED: tomato expression database and highlighted genes conserved during ripening of both species, which in turn represent a foundation for further comparative genomic studies. The cross-species analysis had the secondary aim of examining the efficiency of heterologous (specifically tomato microarray hybridization for candidate gene identification as related to the ripening process. The resulting transcriptomics data revealed coordinated gene expression during fruit ripening of a subset of ripening-related and ethylene responsive genes, further facilitating the analysis of ethylene response during fruit maturation and ripening. Conclusion Our combined strategy based on microarray hybridization enabled transcriptome characterization

    MA-ACS1 and MA-ACO1 are the two major ripening genes in banana and play crucial role in the regulation of ethylene production during ripening. Here, we report a comparative ripening pattern in five different naturally occurring banana cultivars namely Cavendish (AAA), Rasthali (AAB), Kanthali (AB), Poovan (AAB) and Monthan (ABB), which have distinct genome composition. We found a distinct variation in the climacteric ethylene production and in-vivo ACC oxidase activity level during the ripening stages in the five cultivars. We identified the cDNAs for MA-ACS1 and MA-ACO1 from the five cultivars and studied the transcript accumulation patterns of the two genes, which correlated well with the differential timing in the expression of these two genes during ripening. The GCC-box is one of the ethylene-responsive elements (EREs) found in the promoters of many ethylene-inducible genes. We have identified a GCC-box motif (putative ERE) in the promoters of MA-ACS1 and MA-ACO1 in banana cultivars. DNA-protein interaction studies revealed the presence of a GCC-box-specific DNA-binding activity in the fruit nuclear extract and such DNA-binding activity was enhanced following ethylene treatment. South-Western blotting revealed a 25-kDa nuclear protein that binds specifically to GCC-box DNA in the climacteric banana fruit. Together, these results indicate the probable involvement of the GCC-box motif as the cis-acting ERE in the regulation of MA-ACS1 and MA-ACO1 during ripening in banana fruits via binding of specific ERE-binding protein.

    Improving the quality of the non-climacteric fruit, pineapple, is possible with information on the expression of genes that occur during the process of fruit ripening. This can be made known though the generation of partial mRNA transcript sequences known as expressed sequence tags (ESTs). ESTs are useful not only for gene discovery but also function as a resource for the identification of molecular markers, such as simple sequence repeats (SSRs). This paper reports on firstly, the construction of a normalized library of the mature green pineapple fruit and secondly, the mining of EST-SSRs markers using the newly obtained pineapple ESTs as well as publically available pineapple ESTs deposited in GenBank. Sequencing of the clones from the EST library resulted in 282 good sequences. Assembly of sequences generated 168 unique transcripts (UTs) consisting of 34 contigs and 134 singletons with an average length of ≈500 bp. Annotation of the UTs categorized the known proteins transcripts into the three ontologies as: molecular function (34.88%), biological process (38.43%), and cellular component (26.69%). Approximately 7% (416) of the pineapple ESTs contained SSRs with an abundance of trinucleotide SSRs (48.3%) being identified. This was followed by dinucleotide and tetranucleotide SSRs with frequency of 46 and 57%, respectively. From these EST-containing SSRs, 355 (85.3%) matched to known proteins while 133 contained flanking regions for primer design. Both the ESTs were sequenced and the mined EST-SSRs will be useful in the understanding of non-climacteric ripening and the screening of biomarkers linked to fruit quality traits. PMID:22207174

    Despite a re-evaluation of risks in recent years, hormone replacement therapy is still surrounded by controversy. Almost 30% of women in a recent survey sought a natural approach to combat climacteric symptoms. Nevertheless, a large proportion of patients felt that they wanted a good safety profile and strong evidence base for treatment. This article seeks to review the evidence supporting non-hormonal approaches to treatment. There is only conflicting evidence at best to support alpha-2 agonists, e.g. clonidine and limited evidence for dihydroepiandrosterone and natural progesterones. There is limited randomized controlled trial data for gabapentin, selective norepinephrine re-uptake inhibitors (SNRIs) and selective serotonin re-uptake inhibitors (SSRIs), many of these studies being related to breast cancer patients. Of the herbal medicinal products, the largest evidence base rests with phytoestrogens. A Cochrane Database review looking at all types of phytoestrogens, e.g. red clover extracts, dietary soya and soya extracts concluded that there was no evidence to support improvement in climacteric symptoms and the meta-analysis of a 178 studies on soy products was inconsistent. Nevertheless, other studies disagree. Mammographic density is not affected by soy or phytoestrogen products and recent in vitro work shows only a weakly proliferative effect of soy isoflavone on breast cancer cells and evidence that soy isoflavone blocks the proliferative effect of estradiol on these cells. There are no studies looking at clinical outcome measures for cardiovascular disease but a number of studies looking at biochemical markers including arterial wall stiffness and apolipo protein B. Recent studies have also looked at the effects of red clover isoflavone on mood and depression, using specific depression rating scales. Finally, it is important to note that herbal medicinal products should not be used without caution. Some may produce quite marked side-effects in high doses

  12. Engineering melon plants with improved fruit shelf life using the TILLING approach.

    Full Text Available BACKGROUND: Fruit ripening and softening are key traits that have an effect on food supply, fruit nutritional value and consequently, human health. Since ethylene induces ripening of climacteric fruit, it is one of the main targets to control fruit over ripening that leads to fruit softening and deterioration. The characterization of the ethylene pathway in Arabidopsis and tomato identified key genes that control fruit ripening. METHODOLOGY/PRINCIPAL FINDINGS: To engineer melon fruit with improved shelf-life, we conducted a translational research experiment. We set up a TILLING platform in a monoecious and climacteric melon line, cloned genes that control ethylene production and screened for induced mutations that lead to fruits with enhanced shelf life. Two missense mutations, L124F and G194D, of the ethylene biosynthetic enzyme, ACC oxidase 1, were identified and the mutant plants were characterized with respect to fruit maturation. The L124F mutation is a conservative mutation occurring away from the enzyme active site and thus was predicted to not affect ethylene production and thus fruit ripening. In contrast, G194D modification occurs in a highly conserved amino acid position predicted, by crystallographic analysis, to affect the enzymatic activity. Phenotypic analysis of the G194D mutant fruit showed complete delayed ripening and yellowing with improved shelf life and, as predicted, the L124F mutation did not have an effect. CONCLUSIONS/SIGNIFICANCE: We constructed a mutant collection of 4023 melon M2 families. Based on the TILLING of 11 genes, we calculated the overall mutation rate of one mutation every 573 kb and identified 8 alleles per tilled kilobase. We also identified a TILLING mutant with enhanced fruit shelf life. This work demonstrates the effectiveness of TILLING as a reverse genetics tool to improve crop species. As cucurbits are model species in different areas of plant biology, we anticipate that the developed tool will be

    Carnation (Dianthus caryophyllus) flowers exhibit climacteric ethylene production followed by petal wilting, a senescence symptom. DcACS1, which encodes 1-aminocyclopropane-1-carboxylate synthase (ACS), is a gene involved in this phenomenon. We determined the genomic DNA structure of DcACS1 by genomic PCR. In the genome of 'Light Pink Barbara', we found two distinct nucleotide sequences: one corresponding to the gene previously shown as DcACS1, designated here as DcACS1a, and the other novel one designated as DcACS1b. It was revealed that both DcACS1a and DcACS1b have five exons and four introns. These two genes had almost identical nucleotide sequences in exons, but not in some introns and 3'-UTR. Analysis of transcript accumulation revealed that DcACS1b is expressed in senescing petals as well as DcACS1a. Genomic PCR analysis of 32 carnation cultivars showed that most cultivars have only DcACS1a and some have both DcACS1a and DcACS1b. Moreover, we found two DcACS1 orthologous genes with different nucleotide sequences from D. superbus var. longicalycinus, and designated them as DsuACS1a and DsuACS1b. Petals of D. superbus var. longicalycinus produced ethylene in response to exogenous ethylene, accompanying accumulation of DsuACS1 transcripts. These data suggest that climacteric ethylene production in flowers was genetically established before the cultivation of carnation.

    MicroRNAs (miRNAs) are a class of small, endogenous non-coding RNAs that negatively regulate gene expression, resulting in the silencing of target mRNA transcripts through mRNA cleavage or translational inhibition. MiRNAs play significant roles in various biological and physiological processes in plants. However, the miRNA-mediated gene regulatory network in pineapple, the model tropical non-climacteric fruit, remains largely unexplored. Here, we report a complete list of pineapple mature miRNAs obtained from high-throughput small RNA sequencing and precursor miRNAs (pre-miRNAs) obtained from ESTs. Two small RNA libraries were constructed from pineapple fruits and leaves, respectively, using Illumina's Solexa technology. Sequence similarity analysis using miRBase revealed 579,179 reads homologous to 153 miRNAs from 41 miRNA families. In addition, a pineapple fruit transcriptome library consisting of approximately 30,000 EST contigs constructed using Solexa sequencing was used for the discovery of pre-miRNAs. In all, four pre-miRNAs were identified (MIR156, MIR399, MIR444 and MIR2673). Furthermore, the same pineapple transcriptome was used to dissect the function of the miRNAs in pineapple by predicting their putative targets in conjunction with their regulatory networks. In total, 23 metabolic pathways were found to be regulated by miRNAs in pineapple. The use of high-throughput sequencing in pineapples to unveil the presence of miRNAs and their regulatory pathways provides insight into the repertoire of miRNA regulation used exclusively in this non-climacteric model plant.

    Full Text Available Kiwifruit (Actinidia deliciosa (A. Chev. C.F. Liang et A.R. Ferguson, cv. ‘Hayward’ is classified as climacteric fruit and the initiation of endogenous ethylene production following harvest is induced by exogenous ethylene or chilling exposure. To understand the biological basis of this ‘dilemma’, kiwifruit ripening responses were characterized at 20 oC following treatments with exogenous ethylene (100 μL L-1, 20 oC, 24 h or/and chilling temperature (0 oC, 10 d. All treatments elicited kiwifruit ripening and induced softening and endogenous ethylene biosynthesis, as determined by 1-aminocyclopropane-1-carboxylic acid (ACC content and ACC synthase (ACS and ACC oxidase (ACO enzyme activities after 10 d of ripening at 20 oC. Comparative proteomic analysis using two-dimensional gel electrophoresis (2DE-PAGE and nanoscale liquid chromatography coupled to tandem mass spectrometry (nanoLC-MS/MS revealed 81 kiwifruit proteins associated with ripening. Thirty-one kiwifruit proteins were identified as commonly regulated by the three treatments accompanied by dynamic changes of 10 proteins specific to exogenous ethylene, 2 to chilling treatment and 12 to their combination. Ethylene and/or chilling-responsive proteins were mainly involved in disease/defense, energy, protein destination/storage and cell structure/cell wall. Interactions between the identified proteins were demonstrated by bioinformatics analysis, allowing a more complete insight into biological pathways and molecular functions affected by ripening. The present approach provides a quantitative basis for understanding the ethylene- and chilling-induced kiwifruit ripening and climacteric fruit ripening in general.

    The change in 3',5'-cyclic adenosine monophosphate (c-AMP) concentration was observed in various organs of rats in gonadal cycle in adult group and with aging (30, 70, 100, 120 weeks), and in human ovaries with aging. 1) The average c-AMP concentration of ovaries of rats showed a significant change with estrus cycle and was higher in the following sequence: proestrus, diestrus II, diestrus I and estrus phase. This tendency was also seen in hypothalamus and pituitary, but was not statistically significant, 2) The average c-AMP concentration in tissues began to decline significantly from 70 weeks in cerebral cortex and hypothalamus, and from 80 weeks in ovaries. However, on the other hand the concentrations in pituitary, liver and adrenal declined markedly from 100 weeks. 3) The c-AMP in ovaries of 80 weeks rats by pregnant mare serum (PMS) road increased by 0.5-fold in concentration, and by 0.6-fold in whole tissue relative to that of 30 weeks rats. 4) A significant difference in serum LH and FSH level between ovarian artery and vein was not found in cycling mature group, non-cycling climacteric group and post-menopausal group of women. 5) Both average concentrations and total values of c-AMP in ovaries of non-cycling climacteric and post-menopausal women were lower than those of mature cycling women. This fact may imply a different response by ovarian tissues such as corpus luteum, follicle and other tissues to gonadotropin. From these results of c-AMP in tissues, it is concluded that the decline of ovarian function with aging of rats was relatively earlier than pituitary, although being delayed compared with hypothalamus, and were the ovarian function in humans declined in the premenopausal period.

    Full Text Available Abstract Background After menopause, 10–20% of all women have nearly intolerable hot flushes. Long term use of hormone replacement therapy involves a health risk, and many women seek alternative strategies to relieve climacteric complaints. Acupuncture is one of the most frequently used complementary therapies in Norway. We designed a study to evaluate whether Traditional Chinese Medicine acupuncture-care together with self-care is more effective than self-care alone to relieve climacteric complaints. Methods/Design The study is a multi-centre pragmatic randomised controlled trial with two parallel arms. Participants are postmenopausal women who document ≥7 flushes/24 hours and who are not using hormone replacement therapy or other medication that may influence flushes. According to power calculations 200 women are needed to detect a 50% reduction in flushes, and altogether 286 women will be recruited to allow for a 30% dropout rate. The treatment group receives 10 sessions of Traditional Chinese Medicine acupuncture-care and self-care; the control group will engage in self-care only. A team of experienced Traditional Chinese Medicine acupuncturists give acupuncture treatments. Discussion The study tests acupuncture as a complete treatment package including the therapeutic relationship and expectation. The intervention period lasts for 12 weeks, with follow up at 6 and 12 months. Primary endpoint is change in daily hot flush frequency in the two groups from baseline to 12 weeks; secondary endpoint is health related quality of life, assessed by the Women's Health Questionnaire. We also collect data on Traditional Chinese Medicine diagnoses, and we examine treatment experiences using a qualitative approach. Finally we measure biological variables, to examine potential mechanisms for the effect of acupuncture. The study is funded by The Research Council of Norway.

    Development of fruit flesh texture quality traits may involve the metabolism of phenolic compounds. This study presents molecular and biochemical results on the possible role played by cinnamyl alcohol dehydrogenase (CAD; EC 1.1.1.195) during ripening [S3, S4 I (pre-climacteric) and S4 III (climacteric) stages] of peach [Prunus persica (L.) Batsch] fruit with different flesh firmness [non-melting flesh (NMF) 'Oro A'/melting flesh (MF) 'Springcrest' and 'Sanguinella'] and color (blood-flesh Sanguinella). A total of 24 putative full-length PRUPE_CAD genes were identified (in silico analysis) in the peach genome. The most abundant CAD isoforms, encoded by genes located on scaffolds 8 and 6, were probed by specifically developed anti-PRUPE_CAD sc8 and by anti-FaCAD (PRUPE_CAD sc6) polyclonal antibodies, respectively. PRUPE_CAD sc8 proteins (SDS-PAGE and native-PAGE/western blot) appeared responsible for the CAD activity (in vitro/in-gel assays) that increased with ripening (parallel to PRUPE_ACO1 transcripts accumulation and ethylene evolution) only in the mesocarp of Oro A and blood-flesh Sanguinella. Accumulation of PRUPE_CAD sc8 transcripts (semi-quantitative RT-PCR) occurred in all three cultivars, but in Oro A and Springcrest it was not always accompanied by that of the related proteins, suggesting possible post-transcriptional regulation. Flesh firmness, as well as levels of lignin, total phenolics and, where present (Sanguinella), anthocyanins, declined with ripening, suggesting that, at least in the studied peach cultivars, CAD activity is related to neither lignification nor differences in flesh firmness (NMF/MF). Further studies are necessary to clarify whether the high levels of CAD activity/expression in Sanguinella play a role in determining the characteristics of this blood-flesh fruit. PMID:25534876

    Full Text Available Postharvest disorders and rots can produce important economic losses in fruits stored for long time for exportation. The genetic and physiological basis of some disorders in melon (Cucumis melo L. are unknown and particularly the possible relation with climacteric behavior. A collection of melon near-isogenic lines (NILs (SC3-5 and seven more showing climacteric and two non-climacteric ripening pattern were analyzed to study genetic and physiological aspects of fruit disorders and rots. Two non-climacteric (Nicolás; Inodorus Group; and Shongwan Charmi PI161375, Conomon Group and two climacteric cultivars (Fado, Reticulatus Group; Védrantais, Cantaloupensis Group were used as reference. The field was divided in eight blocks containing one three-plant replication for each NIL, two for the parental cultivar Piel de Sapo and one or two for the reference cultivars. Replications evaluated were more than six in the cultivars studied. Plant problems included aphids, powdery mildew, and leaf wind injury. Preharvest fruit disorders included whole fruit cracking in cultivar Védrantais and NIL 5M2, and stylar-end cracking in cultivar Fado. Climacteric NILs with yellow skin were particularly affected by over-ripening, stylar-end cracking, and sunburn during cultivation. At harvest, two NILs showed slight placental tissue necrosis which was inherited from SC and were also detected after storage. Other uncommon disorders seen at harvest or 30 days after storage at 8ºC included warted skin (scarring, flesh discoloration (light brown or translucent areas, hollow flesh disorder, and deep furrow netting inherited from SC. Less common rots included grey mould, bacterial soft rot, Penicillium rot, cottony leak and internal Cladosporium rot. Stylar-end hardness below 20 N·mm-1 was associated with cracking and softening. The incidence of the disorders and rots was too low to confirm that the genetic component played a role in their development

    Cape gooseberry fruits at the maturity stages 3 (yellow greenish or 5 (yellow orange and with calyx drying for 6 hours at 18 or 24ºC, were stored at the temperature of 18ºC and 85 % relative humidity for 20 days, to evaluate physical-chemical and physiological changes. The cape gooseberry, a climacteric fruit, presented the maximum of respiration between 6 and 8 days of storage. The 6th day of storage seems to be crucial due to the very high metabolism and the maximum contents of sugars and acids on this day. Soluble solids tended to increase and the titratable acids went to diminish. The fruit's sugar content was characterized by a major concentration of sucrose, followed by glucose and fructose. While the citric acid showed its highest level at the sixth storage day that of the tartaric acid increased constantly up to 18 days. The fruit maturity stage 3 is that which best conserved the sugars and organic acids evaluated. The maturity index influenced more than calyx drying the postharvest behavior of cape gooseberry. Calyx drying at 24ºC caused the highest climacteric peak and originated the highest loss of fresh weight in fruits harvested at maturity index 5.

Las enzimas antioxidantes son esenciales para las células aeróbicas, puesto que mantienen en niveles aceptables las concentraciones de especies químicas conocidas como radicales libres. Durante el climaterio o etapa perimenopáusica, el cuerpo y metabolismo de una mujer cambia de forma importante, y los mecanismos que regulan el estrés oxidativo no son la excepción. Los estrógenos, per se, son antioxidantes, y esto ha impulsado recientemente estudios sobre los efectos antioxidativos de los estrógenos, como un posible mecanismo preventivo para algunas enfermedades. En los últimos años se le ha brindado gran importancia al papel del estrés oxidativo en la génesis de algunas enfermedades como la ateroesclerosis y la enfermedad cardiovascular, algunos tipos de cánceres y la enfermedad de Alzheimer. Pareciera que los estrógenos sí modifican el equilibro oxidativo / antioxidativo in vivo, sin embargo aun se requieren más estudios para puntualizar el rol de estos como posibles tratamientos preventivos para la menopáusica.The cell carefully regulates the balance between the production of radical oxygen species and antioxidant enzymes levels. Antioxidant enzymes are critical for aerobic cells to maintain within balance free radical production.

    Full Text Available Although ethylene is well known as an essential regulator of fruit development, little work has examined the role ethylene plays in the development and maturation of mulberry (Morus L. fruit. To study the mechanism of ethylene action during fruit development in this species, we measured the ethylene production, fruit firmness, and soluble solids content (SSC during fruit development and harvest. By comparing the results with those from other climacteric fruit, we concluded that Morus fruit are probably climacteric. Genes associated with the ethylene signal transduction pathway of Morus were characterized from M. notabilis Genome Database, including four ethylene receptor genes, a EIN2-like gene, a CTR1-like gene, four EIN3-like genes, and a RTE1-like gene. The expression patterns of these genes were analyzed in the fruit of M. atropurpurea cv. Jialing No.40. During fruit development, transcript levels of MaETR2, MaERS, MaEIN4, MaRTE, and MaCTR1 were lower at the early stages and higher after 26 days after full bloom (DAF, while MaETR1, MaEIL1, MaEIL2, and MaEIL3 remained constant. In ripening fruit, the transcripts of MaACO1 and MaACS3 increased, while MaACS1 and MaACO2 decreased after harvest. The transcripts of MaACO1, MaACO2, and MaACS3 were inhibited by ethylene, and 1-MCP (1-methylcyclopropene upregulated MaACS3. The transcripts of the MaETR-like genes, MaRTE, and MaCTR1 were inhibited by ethylene and 1-MCP, suggesting that ethylene may accelerate the decline of MaETRs transcripts. No significant changes in the expression of MaEIN2, MaEIL1, and MaEIL3 were observed during ripening or in response to ethylene, while the expressions of MaEIL2 and MaEIL4 increased rapidly after 24 h after harvest (HAH and were upregulated by ethylene. The present study provides insights into ethylene biosynthesis and signal transduction in Morus plants and lays a foundation for the further understanding of the mechanisms underlying Morus fruit development and

    Full Text Available Abstract Background Grapevine (Vitis species is among the most important fruit crops in terms of cultivated area and economic impact. Despite this relevance, little is known about the transcriptional changes and the regulatory circuits underlying the biochemical and physical changes occurring during berry development. Results Fruit ripening in the non-climacteric crop species Vitis vinifera L. has been investigated at the transcriptional level by the use of the Affymetrix Vitis GeneChip® which contains approximately 14,500 unigenes. Gene expression data obtained from berries sampled before and after véraison in three growing years, were analyzed to identify genes specifically involved in fruit ripening and to investigate seasonal influences on the process. From these analyses a core set of 1477 genes was found which was similarly modulated in all seasons. We were able to separate ripening specific isoforms within gene families and to identify ripening related genes which appeared strongly regulated also by the seasonal weather conditions. Transcripts annotation by Gene Ontology vocabulary revealed five overrepresented functional categories of which cell wall organization and biogenesis, carbohydrate and secondary metabolisms and stress response were specifically induced during the ripening phase, while photosynthesis was strongly repressed. About 19% of the core gene set was characterized by genes involved in regulatory processes, such as transcription factors and transcripts related to hormonal metabolism and signal transduction. Auxin, ethylene and light emerged as the main stimuli influencing berry development. In addition, an oxidative burst, previously not detected in grapevine, characterized by rapid accumulation of H2O2 starting from véraison and by the modulation of many ROS scavenging enzymes, was observed. Conclusion The time-course gene expression analysis of grapevine berry development has identified the occurrence of two well

    Low temperature storage is widely applied to maintain citrus postharvest fruit quality.In this study,the transcriptional and metabolic changes in the pulp tissue of Citrus reticulata Blanco cv."Ponkan"were studied for three successive months under cold storage by Affymetrix Citrus GeneChip and gaschromatography,respectively.As many as 2 161 differentially expressed transcripts were identifiedbased on the bayesian hierarchical model.The statistical analysis of gene ontology revealed thatdefenselstress-related genes were induced quickly,while autophagy-related genes were overrepresentedin the late sampling stages,suggesting that the functional shift may coincide with the subsequent stepsof chilling development.We further classified the potential regulatory components and concluded thatethylene may play the crucial role in chilling development in this non-climacteric fruit.To cope withcomplex events,53 upregulated transcription factors represented regulatory candidates.Within these,the AP2-EREBP,C2H2 and AS2 gene family were overrepresented.Cold storage also causes alterationsin various metabolic pathways; a keen interest is paid in deciphering expression changes of solublesugar genes as increased evidence that soluble sugars act as both osmolytes and metabolite signalmolecules.Our results will likely facilitate further studies in this field with promising genetic candidatesduring chilling.

    Objective: To determine the prevalence of sexual problems in Iranian women and association of sexual dysfunction with menopausal symptoms. Materials and methods: In this cross-sectional study, 151 married women with the age of 40-60 yearsold who were referred for treatmentto Department of Gynecology in Vali-e-Asr Hospital (Tehran, Iran) from April to July 2012, were recruited. They were evaluated concerning their sexual function in the domains of desire, arousal, lubrication, orgasm, satisfaction and pain with the female sexual function index (FSFI) questionnaire.Menopause rating scale (MRS) was developed for the diagnosis and quantification of climacteric symptoms. Results: Total frequency of sexual dysfunction was 53% with the domains of lubrication, arusal and desire being commonly affected 62%, 70% and 98.5% of cases respectively. There is a relationship between severity of somatic and urogenital symptoms with sexual dysfunction (p = 0.03, p = 0.00 respectively). Conclusion: A considerable percentage of women experienced sexual dysfunctions in this period. Somatic and urogenital symptoms during the menopausal period could be a factor to maintain or intensity of sexual dysfunctions.

    International Nuclear Information System (INIS)

    A study of the effects of minimal processing treatments, both individually or in combinations, was carried out in order to extend the shelf life and to improve the quality of bananas. Pre climacteric bananas at light full three-quarter grade, were either treated with hot water immersion for 1-30 min at 45-55 degree C, or irradiated with electron beams (2.0 MeV, Van de Graaff accelerator), to a dose of 0.1-1.5 kGy. All fruit was stored at 21 ± 1 degree C and relative humidity of 85-95 %. There was no significant delay in ripening of fruit treated with hot water immersion at the above temperatures. Some damage to fruit particularly peel scalding at ends occurred at the higher temperatures (>50 degree C). The 50 degree C, 5 minutes immersion was selected for further study. Irradiation to 0.1-0.3 kGy delayed the ripening (up to 3 days) without affecting fruit quality. Doses greater than 0.4 kGy resulted in extensive discoloration and fruit splitting. No significant differences could be detected organoleptically between bananas irradiated at 0.15 kGy and the control. Results of the physico-chemical attributes of the bananas were reported for fruits at colour stage 5 and after 10 and 15 days of storage. The combination treatment of hot water immersion and irradiation at the above settings further extended the shelf life of the banana fruits

    Full Text Available Strawberry is a non-climacteric fruit, with a short postharvest life. The loss of fruit quality may be due, among other factors to damage caused by pathogens. Among the most common fungi are causing gray mold (Botrytis cinerea and white rot (Rhizopus stolonifer two phytopathogenic impact on their growth rate which allows you to colonize the surface of these caused major economic losses. An alternative to control damage in fruit postharvest pathogens usingmicrobial antagonists may be present in the plant or fruit, but at low densities. In this study bacteria were isolated from leaf tissue and wild strawberry fruit (Duchesnea indicates Andr. Fock and comercial strawberry. Those isolates that were selected had the highest percentages of inhibition of mycelial growth of both pathogens in vitro. We isolated a total of 32 strains of which 15 came from wild strawberry and 24 commercial strawberry. Only nine strains were obtained with biocontrol potential for one or both pathogens. The highest percentages of mycelial growth inhibition ranged from 67.1% and 81.7% for Botrytis cinerea and 45.5% to 73.2% for Rhizopus stolonifer. These were obtained from four isolates two of them from wild strawberry and the others from commercial strawberry, all with ability to control both pathogens.

    Apple is one of the most economically important horticultural fruit crops worldwide. It is critical to gain insights into fruit ripening and softening to improve apple fruit quality and extend shelf life. In this study, forward and reverse suppression subtractive hybridization libraries were generated from ‘Taishanzaoxia’ apple fruits sampled around the ethylene climacteric to isolate ripening- and softening-related genes. A set of 648 unigenes were derived from sequence alignment and cluster assembly of 918 expressed sequence tags. According to gene ontology functional classification, 390 out of 443 unigenes (88%) were assigned to the biological process category, 356 unigenes (80%) were classified in the molecular function category, and 381 unigenes (86%) were allocated to the cellular component category. A total of 26 unigenes differentially expressed during fruit development period were analyzed by quantitative RT-PCR. These genes were involved in cell wall modification, anthocyanin biosynthesis, aroma production, stress response, metabolism, transcription, or were non-annotated. Some genes associated with cell wall modification, anthocyanin biosynthesis and aroma production were up-regulated and significantly correlated with ethylene production, suggesting that fruit texture, coloration and aroma may be regulated by ethylene in ‘Taishanzaoxia’. Some of the identified unigenes associated with fruit ripening and softening have not been characterized in public databases. The results contribute to an improved characterization of changes in gene expression during apple fruit ripening and softening. PMID:26719904

    Fruit ripening involves a complex interplay between ethylene and ripening-associated transcriptional regulators. Ethylene Response Factors (ERFs) are downstream components of ethylene signaling, known to regulate the expression of ethylene-responsive genes. Although fruit ripening is an ethylene-regulated process, the role of ERFs remains poorly understood. The role of Sl-ERF.B3 in tomato (Solanum lycopersicum) fruit maturation and ripening is addressed here using a chimeric dominant repressor version (ERF.B3-SRDX). Over-expression of ERF.B3-SRDX results in a dramatic delay of the onset of ripening, enhanced climacteric ethylene production and fruit softening, and reduced pigment accumulation. Consistently, genes involved in ethylene biosynthesis and in softening are up-regulated and those of carotenoid biosynthesis are down-regulated. Moreover, the expression of ripening regulators, such as RIN, NOR, CNR and HB-1, is stimulated in ERF.B3-SRDX dominant repressor fruits and the expression pattern of a number of ERFs is severely altered. The data suggest the existence of a complex network enabling interconnection between ERF genes which may account for the pleiotropic alterations in fruit maturation and ripening. Overall, the study sheds new light on the role of Sl-ERF.B3 in the transcriptional network controlling the ripening process and uncovers a means towards uncoupling some of the main ripening-associated processes.

    Certain MADS-box transcription factors play central roles in regulating fruit ripening. RIPENING INHIBITOR (RIN), a tomato MADS-domain protein, acts as a global regulator of ripening, affecting the climacteric rise of ethylene, pigmentation changes, and fruit softening. Previously, we showed that two MADS-domain proteins, the FRUITFULL homologs FUL1 and FUL2, form complexes with RIN. Here, we characterized the FUL1/FUL2 loss-of-function phenotype in co-suppressed plants. The transgenic plants produced ripening-defective fruits accumulating little or no lycopene. Unlike a previous study on FUL1/FUL2 suppressed tomatoes, our transgenic fruits showed very low levels of ethylene production, and this was associated with suppression of the genes for 1-aminocyclopropane-1-carboxylic acid synthase, a rate-limiting enzyme in ethylene synthesis. FUL1/FUL2 suppression also caused the fruit to soften in a manner independent of ripening, possibly due to reduced cuticle thickness in the peel of the suppressed tomatoes.

    Abscisic acid (ABA) has been proven to be involved in the regulation of climacteric fruit ripening, but a comprehensive investigation of its influence on ripening related processes is still lacking. By applying the next generation sequencing technology, we conducted a comparative analysis of the effects of exogenous ABA and NDGA (Nordihydroguaiaretic acid, an inhibitor of ABA biosynthesis) on tomato fruit ripening. The high throughput sequencing results showed that out of the 25728 genes expressed across all three samples, 10388 were identified as significantly differently expressed genes. Exogenous ABA was found to enhance the transcription of genes involved in pigments metabolism, including carotenoids biosynthesis and chlorophyll degradation, whereas NDGA treatment inhibited these processes. The results also revealed the crucial role of ABA in flavonoids synthesis and regulation of antioxidant system. Intriguingly, we also found that an inhibition of endogenous ABA significantly enhanced the transcriptional abundance of genes involved in photosynthesis. Our results highlighted the significance of ABA in regulating tomato ripening, which provided insight into the regulatory mechanism of fruit maturation and senescence process.

    Our knowledge of the factors mediating ethylene-dependent ripening of climacteric fruit remains limited. The transcription of ethylene-regulated genes is mediated by ethylene response factors (ERFs), but mutants providing information on the specific role of the ERFs in fruit ripening are still lacking, likely due to functional redundancy among this large multigene family of transcription factors. We present here a comprehensive expression profiling of tomato (Solanum lycopersicum) ERFs in wild-type and tomato ripening-impaired tomato mutants (Never-ripe [Nr], ripening-inhibitor [rin], and non-ripening [nor]), indicating that out of the 77 ERFs present in the tomato genome, 27 show enhanced expression at the onset of ripening while 28 display a ripening-associated decrease in expression, suggesting that different ERFs may have contrasting roles in fruit ripening. Among the 19 ERFs exhibiting the most consistent up-regulation during ripening, the expression of 11 ERFs is strongly down-regulated in rin, nor, and Nr tomato ripening mutants, while only three are consistently up-regulated. Members of subclass E, SlERF.E1, SlERF.E2, and SlERF.E4, show dramatic down-regulation in the ripening mutants, suggesting that their expression might be instrumental in fruit ripening. This study illustrates the high complexity of the regulatory network connecting RIN and ERFs and identifies subclass E members as the most active ERFs in ethylene- and RIN/NOR-dependent ripening.

    Modelling of metabolic networks is a powerful tool to analyse the behaviour of developing plant organs, including fruits. Guided by our current understanding of heterotrophic metabolism of plant cells, a medium-scale stoichiometric model, including the balance of co-factors and energy, was constructed in order to describe metabolic shifts that occur through the nine sequential stages of Solanum lycopersicum (tomato) fruit development. The measured concentrations of the main biomass components and the accumulated metabolites in the pericarp, determined at each stage, were fitted in order to calculate, by derivation, the corresponding external fluxes. They were used as constraints to solve the model by minimizing the internal fluxes. The distribution of the calculated fluxes of central metabolism were then analysed and compared with known metabolic behaviours. For instance, the partition of the main metabolic pathways (glycolysis, pentose phosphate pathway, etc.) was relevant throughout fruit development. We also predicted a valid import of carbon and nitrogen by the fruit, as well as a consistent CO2 release. Interestingly, the energetic balance indicates that excess ATP is dissipated just before the onset of ripening, supporting the concept of the climacteric crisis. Finally, the apparent contradiction between calculated fluxes with low values compared with measured enzyme capacities suggest a complex reprogramming of the metabolic machinery during fruit development. With a powerful set of experimental data and an accurate definition of the metabolic system, this work provides important insight into the metabolic and physiological requirements of the developing tomato fruits.

    The developmental process of ripening is unique to fleshy fruits and a key factor in fruit quality. The tomato (Solanum lycopersicum) MADS-box transcription factor RIPENING INHIBITOR (RIN), one of the earliest-acting ripening regulators, is required for broad aspects of ripening, including ethylene-dependent and -independent pathways. However, our knowledge of direct RIN target genes has been limited, considering the broad effects of RIN on ripening. In a recent work published in The Plant Cell, we identified 241 direct RIN target genes by chromatin immunoprecipitation coupled with DNA microarray (ChIP-chip) and transcriptome analysis. Functional classification of the targets revealed that RIN participates in the regulation of many biological processes including well-known ripening processes such as climacteric ethylene production and lycopene accumulation. In addition, we found that ethylene is required for the full expression of RIN and several RIN-targeting transcription factor genes at the ripening stage. Here, based on our recently published findings and additional data, we discuss the ripening processes regulated by RIN and the interplay between RIN and ethylene.

    Full Text Available Abstract Background Papaya (Carica papaya L. is a commercially important crop that produces climacteric fruits with a soft and sweet pulp that contain a wide range of health promoting phytochemicals. Despite its importance, little is known about transcriptional modifications during papaya fruit ripening and their control. In this study we report the analysis of ripe papaya transcriptome by using a cross-species (XSpecies microarray technique based on the phylogenetic proximity between papaya and Arabidopsis thaliana. Results Papaya transcriptome analyses resulted in the identification of 414 ripening-related genes with some having their expression validated by qPCR. The transcription profile was compared with that from ripening tomato and grape. There were many similarities between papaya and tomato especially with respect to the expression of genes encoding proteins involved in primary metabolism, regulation of transcription, biotic and abiotic stress and cell wall metabolism. XSpecies microarray data indicated that transcription factors (TFs of the MADS-box, NAC and AP2/ERF gene families were involved in the control of papaya ripening and revealed that cell wall-related gene expression in papaya had similarities to the expression profiles seen in Arabidopsis during hypocotyl development. Conclusion The cross-species array experiment identified a ripening-related set of genes in papaya allowing the comparison of transcription control between papaya and other fruit bearing taxa during the ripening process.

    The gaseous plant hormone ethylene is involved in many physiological processes including climacteric fruit ripening, in which it is a key determinant of fruit quality. A detailed model that describes ethylene biochemistry dynamics is missing. Often, kinetic modeling is used to describe metabolic networks or signaling cascades, mostly ignoring the link with transcriptomic data. We have constructed an elegant kinetic model that describes the transfer of genetic information into abundance and metabolic activity of proteins for the entire ethylene biosynthesis pathway during fruit development and ripening of tomato (Solanum lycopersicum). Our model was calibrated against a vast amount of transcriptomic, proteomic and metabolic data and showed good descriptive qualities. Subsequently it was validated successfully against several ripening mutants previously described in the literature. The model was used as a predictive tool to evaluate novel and existing hypotheses regarding the regulation of ethylene biosynthesis. This bottom-up kinetic network model was used to indicate that a side-branch of the ethylene pathway, the formation of the dead-end product 1-(malonylamino)-1-aminocyclopropane-1-carboxylic acid (MACC), might have a strong effect on eventual ethylene production. Furthermore, our in silico analyses indicated potential (post-) translational regulation of the ethylene-forming enzyme ACC oxidase.

    In banana, ethylene production for ripening is accompanied by a dramatic increase in 1-aminocyclopropane-1-carboxylate (ACC) content, transcript level of Musa acuminata ACC synthase 1 (MA-ACS1) and the enzymatic activity of ACC synthase 1 at the onset of the climacteric period. MA-ACS1 catalyses the conversion of S-adenosyl-L-methionine (SAM) to ACC, the key regulatory step in ethylene biosynthesis. Multiple sequence alignments of 1-aminocyclopropane-1-carboxylate synthase (ACS) amino acid sequences based on database searches have indicated that MA-ACS1 is a highly conserved protein across the plant kingdom. This report describes an in silico analysis to provide the first important insightful information about the sequential, structural and phylogenetic characteristics of MA-ACS1. The three-dimensional structure of MA-ACS1, constructed based on homology modelling, in combination with the available data enabled a comparative mechanistic analysis of MA-ACS1 to explain the catalytic roles of the conserved and non-conserved active site residues. We have further demonstrated that, as in apple and tomato, banana- ACS1 (MA-ACS1) forms a homodimer and a complex with cofactor pyridoxal-5'-phosphate (PLP) and inhibitor aminoethoxyvinylglycine (AVG). We have also predicted that the residues from the PLP-binding pocket, essential for ligand binding, are mostly conserved across the MA-ACS1 structure and the competitive inhibitor AVG binds at a location adjacent to PLP.

    The effects of hot water treatment in alleviating chilling injury and reducing ultrastructural damage of mature-green cherry tomatoes (Lycopersicun esculentum cv. cerasiform Alef) were investigated. Mature-green cherry tomato fruits were treated in water at 40℃ or 45℃ for 5 rain or 15 rain, and then stored at 5℃ for 19 days followed by ripening at 20℃. Water treatment at 40℃ for 15 rain increased tolerance of cherry tomato fruits to chilling stress, indicating as low outbreak of skin lesion, high color a* value, and low electrolyte leakage. Treated fi'uits showed typical climacteric respiration and developed normal red color with chlorophyll degradation and lyeopene accumulation during ripening, while fruits without treatment failed to develop red color and suffered skin lesion. After 19 days of chilling, heated fruits showed the conversion of chloroplast to ehromoplast with the disappearance of thylakoids. Mitochondria and other cell organelles were not adversely affected in treated fruits. However, ultrastruetures in periearp cells in control fruits severely damaged with extensive disorganization of cytoplasm, swelled chloroplasts, distorted and unstacked thylakoids. Chloroplast was the first and most severely impacted organelle by chilling stress. Hot water treatment (40℃ for 15 min) before storage alleviated chilling injury in cherry tomato fruits. The results suggest that chilling injury is related with the damage of cell structure under chilling stress.

    Full Text Available The advent of highly active antiretroviral therapy (HAART has caused a reduction in mortality, thus contributing to an increase in the number of women with HIVࢧAIDS who reach the climacteric period, experience decline in ovarian function, and develop complications of viral infection and HAART, which can accelerate bone loss. The aim of this study was to detect possible alterations in the jaws of HIV-infected women by panoramic radiography. The study comprised a total of 120 women above 40 years of age who were divided into the following two groups: women who are HIV positive (Group I and women with no known HIV infection (Group II. Measurement of the following three radiomorphometric indexes was performed by panoramic radiography: Mental Index (MI, Panoramic Mandibular Index (PMI and Antegonial Depth (AD. A total of 70% of women in the control group and 50% of women in the HIV group were in the postmenopausal period, and the average values of both MI (p = 0.0054 and AD (p < 0.0001 for this period were lower in the HIV group than in the control group. For patients who were in the premenopausal period, the average AD was lower in the HIV group than in the control group (p = 0.0003. Despite the difference in the average age between groups, greater bone resorption in the mandible was found in the group of HIV-positive women.

    Seedless avocado fruit are produced alongside seeded fruit in the cultivar Arad, and both reach maturity at the same time. Using this system, it was possible to show that avocado seed inhibits the ripening process: seedless fruits exhibited higher response to exogenous ethylene already at the fruitlet stage, and also at the immature and mature fruit stages. They produced higher CO₂ levels, and the ethylene peak was apparent at the fruitlet stage of seedless fruit, but not of seeded ones. The expression levels of PaETR, PaERS1 and PaCTR1 on the day of harvest at all developmental stages were very similar between seeded and seedless fruit, except that PaCTR1 was higher in seedless fruit only at very early stages. This expression pattern suggests that the seed does not have an effect on components of the ethylene response pathway when fruits are just picked. The expression of MADS-box genes, PaAG1 and PaAGL9, preceded the increase in ethylene production of mature seeded fruit, but not at earlier stages. However, only PaAGL9 was induced in seedless fruit at early stages of development. Taken together, these data suggest that these genes are perhaps involved in climacteric response in seeded fruit, and the seed is responsible for their induction at normal fruit ripening.

    Tibolone, a synthetic steroid used for the prevention of osteoporosis and the treatment of climacteric symptoms in post-menopausal women, may exert tissue selective estrogenic actions acting on estrogen receptors (ERs). We previously showed that tibolone protects human T98G astroglial cells against glucose deprivation (GD). In this study we have explored whether the protective effect of tibolone on these cells is mediated by ERs. Experimental studies showed that both ERα and ERβ were involved in the protection by tibolone on GD cells, being ERβ preferentially involved on these actions over ERα. Tibolone increased viability of GD cells by a mechanism fully blocked by an ERβ antagonist and partially blocked by an ERα antagonist. Furthermore, ERβ inhibition prevented the effect of tibolone on nuclear fragmentation, ROS and mitochondrial membrane potential in GD cells. The protective effect of tibolone was mediated by neuroglobin. Tibolone upregulated neuroglobin in T98G cells and primary mouse astrocytes by a mechanism involving ERβ and neuroglobin silencing prevented the protective action of tibolone on GD cells. In summary, tibolone protects T98G cells by a mechanism involving ERβ and the upregulation of neuroglobin. PMID:27250720

    Background The climacteric phase of menopausal transition (perimenopause) is marked by reproductive hormone fluctuations and reduced cognitive capacity. Exercise enhances neurocognitive performance. However, auditory perceptual sensitivity has not been examined. Purpose This study aimed to determine the effect of aerobic exercise on the response speed (reaction time) and error rate during auditory processing among perimenopausal women. Methods Three pitches (500, 1000, and 2000 Hz) were used during a simple auditory discrimination task, which was performed before and after exercise. We included 14 perimenopausal women and 17 right-handed young women (aged 46-54 years and 18-22 years, respectively). To achieve similar exercise intensity in both groups, we proposed two types of physical activities for each group. Mixed models statistics were used to analyze the reaction time and error rate before and after training in the two groups. Results Perimenopausal women exhibited a significantly longer reaction time than young women during the baseline auditory discrimination task (p performance differs between the two groups. Aerobic exercise improves auditory discrimination performance specifically for perimenopausal women. These results provide preliminary evidence concerning the acoustic features of middle-aged women, underscoring the importance of exercise for preventing decline in auditory cognitive function in perimenopausal women.

    Full Text Available To learn how the endogenous polyphenols may play a role in fruit ripening and senescence, apple pulp discs were used as a model to study the influences of chlorogenic acid (CHA, a major polyphenol in apple pulp on fruit ripening and senescence. Apple ('Golden Delicious' pulp discs prepared from pre-climacteric fruit were treated with 50 mg L(-1 CHA and incubated in flasks with 10 mM MES buffer (pH 6.0, 11% sorbitol. Compared to the control samples, treatment with CHA significantly reduced ethylene production and respiration rate, and enhanced levels of firmness and soluble solids content of the pulp discs during incubation at 25°C. These results suggested that CHA could retard senescence of the apple pulp discs. Proteomics analysis with sodium dodecyl sulfate-polyacrylamide gel electrophoresis and mass spectrometry (MALDI-TOF/TOF revealed that the expressions of several key proteins correlated to fruit ripening and senescence were affected by the treatment with CHA. Further study showed that treating the pulp discs with CHA remarkably reduced levels of lipoxygenase, β-galactosidase, NADP-malic enzyme, and enzymatic activities of lipoxygenase and UDP-glucose pyrophosphorylase, all of which are known as promoters of fruit ripening and senescence. These results could provide new insights into the functions of endogenous phenolic compounds in fruit ripening and senescence.

    Full Text Available Mango (Mangifera indica L. is an important fruit of the world owing to its pleasant aroma and taste. In this investigation, the influence of gibberellic acid (GA3 at concentrations of 0, 50, 100 and 150 mg∙l-1 water sprayed 20 days before commercial harvest on postharvest behavior and quality of mango cv. ‘Himsagar’ was studied under ambient storage conditions. GA3 (100 and 150 mg∙l-1 delayed the onset of ripening and caused a reduction in respiration rate as compared to the untreated fruits and retained the total chlorophyll content of fruit peel. Pre-harvest spray of GA3 at 100 mg∙l-1 significantly delayed the onset of the climacteric rise of CO2 production, which depicted delayed ripening over control. The treated fruits also remained firmer and maintained the freshness during storage. Treatment with 100 mg∙l-1 GA3 could be a useful method to extend postharvest life and availability of mango with appreciable quality.

    The recent report of a two-fold increase in esophageal cancer in women taking oral bisphosphonates is yet another reason to question current relegation of hormone replacement therapy (HRT) to a minor role in the correction of many problems occurring in the younger postmenopausal woman. Women under the age of 60 years with low bone density, flushes, sweats, vaginal dryness, loss of libido and climacteric depression would be treated with estrogens by gynecologists and most general practitioners. It is regrettable that bone physicians use bisphosphonates as first-line therapy in this age group, in spite of the growing number of serious complications reported. Similarly, psychiatrists have little experience in the use of estrogens for the reproductive depression syndrome of postnatal depression, premenstrual depression and perimenopausal depression, but use antidepressants. The adverse effects reported in the 2002 Women's Health Initiative study are given as justification for not using estrogens, although serious complications did not occur in women starting HRT before the age of 60 years. But, in reality, the objection to estrogens from psychiatrists and bone physicians preceded this study by decades and was a result of their unfamiliarity with this treatment. Regrettably, PROFOX (PROzac + FOsomaX) will become an established treatment for women who really need estrogens. PMID:21105839

    In the last few years more women of climacteric age, living in urban areas, have been seeking medical care. In 1989, on the invitation of 6 women's organizations in Jakarta and other cities, the Indonesian Menopause Society gave talks and held discussions in cooperation with the Department of Obstetrics and Gynaecology, Faculty of Medicine of the University of Indonesia/Dr. Cipto Mangunkusumo Hospital, Jakarta. These occasions were used to accumulate data from women participants of 40 years of age and older. The age of the respondents ranged between 40-59 years. Most were 42 years old (13.9%). Ninety-four percent were still married. Twenty-five percent had three living children. Sixty-three percent of the respondents were high school graduates who worked full time (33%), part time, or were unemployed. The average menarche age was 13 and menopausal age 50-51. Menopausal complaints were rare, hence medical consultations were rare. Tranquilizers were prescribed for those who did seek medical help. This data constitutes the basis of the formulation of a strategy to solve menopause related problems in Indonesia, where female life expectancy, and the contribution of women to society, is on the increase.

    Kamisyoyosan (KSS) and Tokisyakuyakusan (TSS) are widely used herbal formulas in Japanese traditional kampo medicine to relieve the symptoms occurred in climacteric disturbance. Since Japanese physicians frequently prescribe these formulas combined with etizolam, one of benzodiazepine anxiolytics, we evaluated the pharmacokinetic interaction between KSS or TSS and etizolam, and in vitro inhibitory effect of KSS and TSS on rat cytochrome P450 (CYP) 3A activity in rat microsomes, to obtain drug information to prevent from disadvantage or adverse effects by their combined therapy. In in vitro experiment, KSS and TSS inhibited CYP3A activity comparable to grapefruit juice. However in in vivo experiments, oral administration of KSS did not influence the plasma concentration profile of etizolam. The maximum concentration (Cmax) of etizolam was significantly reduced when TSS was co-administered at 20 times amount of human daily dosage. Since the double of human daily dose of TSS did not suppress the absorption of etizolam, TSS would not influence the pharmacokinetics of etizolam at the usual clinical dosage. Since both KSS and TSS did not influence the metabolism of etizolam, the result of in vitro experiment would not reflect to that of in vivo experiment or in clinic. The combination of etizolam with KSS or TSS at usual dosage would not cause drug interaction. PMID:15684484

The changes of body mass, the uterus mass, fine structure of bone, thighbone density and calcium content of groups were observed.Results: Compared with control group, the different indicators of mice improved in a dose-dependent manner after lavage of Gegen. The above indicators in high- and middle-dose groups were similar to those in control group, and the therapeutic effect in high- and middle-dose groups was as good as or superior to that in estradiol group. However, uterus mass in Gegen-treated groups didn’t increase.Conclusion: Gegen, which has anti-osteoporosis effect like estradiol and doesn’t stimulate uterus, is applicable for the prevention and treatment of climacteric osteoporosis.

    Seedless avocado fruit are produced alongside seeded fruit in the cultivar Arad, and both reach maturity at the same time. Using this system, it was possible to show that avocado seed inhibits the ripening process: seedless fruits exhibited higher response to exogenous ethylene already at the fruitlet stage, and also at the immature and mature fruit stages. They produced higher CO₂ levels, and the ethylene peak was apparent at the fruitlet stage of seedless fruit, but not of seeded ones. The expression levels of PaETR, PaERS1 and PaCTR1 on the day of harvest at all developmental stages were very similar between seeded and seedless fruit, except that PaCTR1 was higher in seedless fruit only at very early stages. This expression pattern suggests that the seed does not have an effect on components of the ethylene response pathway when fruits are just picked. The expression of MADS-box genes, PaAG1 and PaAGL9, preceded the increase in ethylene production of mature seeded fruit, but not at earlier stages. However, only PaAGL9 was induced in seedless fruit at early stages of development. Taken together, these data suggest that these genes are perhaps involved in climacteric response in seeded fruit, and the seed is responsible for their induction at normal fruit ripening.

    Full Text Available Minimally processed broccoli are perishable product because it still has some metabolism process during the storage period. One of the metabolism process is respiration. Respiration rate is varied depend on the commodity and storage temperature. The purpose of this research are: to review the respiration pattern of minimally processed broccoli during storage period, to study the effect of storage temperature to respiration rate, and to review the correlation between respiration rate and temperature based on Arrhenius model. Broccoli from farming organization “Agro Segar” was processed minimally and then measure the respiration rate. Closed system method is used to measure O2 and CO2 concentration. Minimally processed broccoli is stored at a temperature of 0oC, 5oC, 10oC and 15oC. The experimental design used was completely randomized design of the factors to analyze the rate of respiration. The result shows that broccoli is a climacteric vegetable. It is indicated by the increasing of O2 consumption and CO2 production during senescence phase. The respiration rate increase as high as the increasing of temperature storage. Models Arrhenius can describe correlation between respiration rate and temperature with R2 = 0.953-0.947. The constant value of activation energy (Eai and pre-exponential factor (Roi from Arrhenius model can be used to predict the respiration rate of minimally processed broccoli in every storage temperature

    A questionnaire-based study was performed in an area of about 16 ha near a main road in Tokyo to elucidate any relations between road traffic noise and the effects of this noise among women living on both sides of the road. Questions concerned annoyance, sleep disturbance, interference with daily activities, health-related symptoms and disease histories. 366 inhabitants were analyzed. Dose-response relationships were found in high reported responses to noisiness, annoyance, dissatisfaction with the nearby environment and interference with listening to TV, conversation and reading. It was also found that the number of high responses to questions increases clearly at noise levels above 70 dB(A),Leq(24h), with regard to interference with thinking and sleep disturbance (waking during the night), fatigue, headache, gastroenteric disorders, loss of appetite, depression and irritation. Furthermore, there was an increase in reports of disease histories with noise above 70 dB(A) for climacteric disturbances, and at noise above 65 dB(A) for deafness, heart disease and hypercholestrolemia. These all suggest that noise may be related to the health status of inhabitants living in areas with heavy road traffic. A noise level of 65 dB(A) or 70 dB(A) inLeq(24h)was the critical point above which respondents indicated increased effects on health and reports of disease increased.

    The aril around the seeds of Gac fruit is rich in fatty acids and carotenoids (lycopene and β-carotene). Understanding how these qualities are affected by fruit maturity at harvest may identify indices for quality assessment. Some physical and chemical properties of Gac fruit were determined for fruit harvested between 8 and 16 weeks after pollination (WAP). Fruit respiration rates and ethylene production rates were assessed after harvest and up to 20 days in storage at 20°C. Fruit harvested at 14 WAP had the highest oil (0.27 ± 0.02 g/g DW), lycopene content (0.45 ± 0.09 mg/g FW), and β-carotene content (0.33 ± 0.05 mg/g FW) which declined by 16 WAP. External skin color and aril TSS were indicative of oil and carotenoid contents in aril. Skin color, TSS and potentially firmness were good indices of fruit quality. Harvesting less mature fruit at 12 WAP would be practical as the fruit were firmer and more capable of transport; however, quality during postharvest ripening may be limited. Fruits continued to ripen after they were harvested and an ethylene peak in the least mature fruit may reflect a climacteric behavior but this needs further investigation. PMID:27004120

    Full Text Available Consistency of fruit quality is extremely important in horticulture. Fruit growth and quality in nectarine are affected by fruit position in the canopy, related to the tree shape. The “open shaped” training systems, such as Tatura Trellis, improve fruit growth and quality. The Index of Absorbance Difference (IAD is a new marker that characterizes climacteric fruit during ripening. A study on fruit ripening was performed by using the IAD on nectarine to monitor fruit maturity stages of two cultivars trained as Tatura Trellis in Victoria, Australia. Fruit of cv “Summer Flare 34” (“SF34” grown in different positions on the tree showed high ripening homogeneity. Fruit harvested at a similar ripening stage showed fruit firmness and soluble solid content homogeneity. Fruits from hand-thinned variety “Summer Flare 26” (“SF26” were larger in size, had advanced ripening, and showed greater homogeneity. For “SF26”, a weak correlation between IAD and SSC was observed. The experiment showed that the Tatura Trellis training system is characterized by high homogeneity of nectarine fruit when coupled with a proper management of fruit density. It also confirmed that the IAD could be used as new nondestructive maturity index for nectarine fruit quality assessment in the field.

    Full Text Available Cocona (Solanum sessiliflorum Dunal is an important genetic resource that has been traditionally used for a variety of purposes, including food, medical and cosmetics applications. The objective of this study was evaluated the quality and the period of postharvest shelf life of cocona 'Mosquet", through the physical, chemical and physiological characterization of fruits stored under the ambient conditions. Physiologically mature fruits were harvested from an orchard, washed with tap water and soaked in a solution of the fungicide Prochloraz (49.5 g/100 L of water for 5 minutes. After air drying, the fruits were packed in plastic containers and stored at 24 ± 2 ºC and relative humidity 60 ± 5% for 15 days. The fruits developed a respiratory climacteric respiratory patern and remained fit for consumption up to day 6 of storage, that is, without visual symptoms of loss of water and firmness. At this stage, the fruits showed firmness of 117,42 kPa, soluble solids of 6.62º Brix and citric acid of 1.22 %.

    Full Text Available Sweet cherry, a non-climacteric fruit, is usually cold-stored during postharvest to prevent over-ripening. The aim of the study was to evaluate the role of abscisic acid (ABA on fruit growth and ripening of this fruit, considering as well its putative implication in over-ripening and effects on quality. We measured the endogenous concentrations of ABA during the ripening of sweet cherries (Prunus avium L. var. Prime Giant collected from orchard trees and in cherries exposed to 4ºC and 23ºC during 10d of postharvest. Furthermore, we examined to what extent endogenous ABA concentrations were related to quality parameters, such as fruit biomass, anthocyanin accumulation and levels of vitamins C and E. Endogenous concentrations of ABA in fruits increased progressively during fruit growth and ripening on the tree, to decrease later during postharvest at 23ºC. Cold treatment, however, increased ABA levels and led to an inhibition of over-ripening. Furthermore, ABA levels positively correlated with anthocyanin and vitamin E levels during preharvest, but not during postharvest. We conclude that ABA plays a major role in sweet cherry development, stimulating its ripening process and positively influencing quality parameters during preharvest. The possible influence of ABA preventing over-ripening in cold-stored sweet cherries is also discussed.

    The changes of physiological and biochemical indices in jujube fruits during the late development were investigated from 6-year-old jujube trees (Zizyphus jujuba Mill. cv. Lingwuchangzao). The results showed that the flesh firmness decreased slowly from white-green stage to full-red stage, being significantly related with the developmental maturity of jujube fruits negatively, the correlation coefficient reached -0.980 3**. The contents of ascorbic acid and titratable acid in jujube fruits were significantly related with the developmental process of jujube fruits negatively or positively, the correlation coef-ficients were -0.973 1** and + 0.974 6** respectively. The contents of soluble solids, total sugar, and sucrose increased with jujube ripening, while the relative sweetness of jujube fruits showed the same variation pattern, the correlation coefficients were 0.996 6** , 0.988 0** , and 0.982 8**, respec-tively. Befcre white-green stage during fruit development,the accumulation d moncsaccharide was predom/nant in jujube fruits, following a fast accumula-tion of sucrose, indicating that the main component of sugars is sucrose at the crisp-ripe stage. Furthermore, the starch content of the flesh reached the peak at about thirty percentage of jujube maturity, being 51.54 mg/100 g · FW. The respiratory rates varied between 10 mg/(kg·h) and CO2 26 mg/(kg·h) after fruit turning red and before softening, indicating a non-climacteric respiratory type.

    Agnus Castus Fruit is defined in the European Pharmacopoeia as the dried ripe fruit of Vitex agnus-castus. In Europe it is used as a medicine targeting premenstrual syndrome and climacteric disorder. In Japan, Agnus Castus Fruit is becoming popular as a raw material for over-the-counter drugs and health food products, though its congenic species, Vitex rotundifolia and Vitex trifolia, have been used as Shrub Chaste Tree Fruit in traditional medicines. Therefore, it is important to discriminate these Vitex plants from the viewpoint of regulatory science. Here we tried to identify putative marker compounds that distinguish between Agnus Castus Fruit and Shrub Chaste Tree Fruit. We analyzed extracts of each crude drug by liquid chromatography-mass spectrometry, and performed differential analysis by comparison of each chromatogram to find one or more peaks characteristic of Agnus Castus Fruit. A peak was isolated and identified as an equilibrium mixture of new compounds named chastol (1) and epichastol (1a). The planar structures of 1 and 1a were determined spectroscopically. Their relative configurations were revealed by nuclear Overhauser effect spectroscopy and differential nuclear Overhauser effect-NMR data. Since avoiding contamination from closely related species is needed for the quality control of natural pharmaceuticals, this information will be valuable to establish a method for the quality control of both, Agnus Castus Fruit and Shrub Chaste Tree Fruit products.

    The roles of reactive oxygen species (ROS) as both toxic by-products and as signaling molecules have been reported in fruit development and ripening. Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) play important roles in balancing the induction and removal of ROS in plants, and are respectively encoded by families of closely homologous genes. In the present study, we investigated the roles of ROS and the above-mentioned antioxidant genes during the development and ripening of peach fruit. The experimental results indicated that O2(-) and H2O2 acted as potential signaling molecules in the middle stage of fruit development, and only H2O2 might function as a main toxic molecule to stimulate lipid peroxidation and oxidative stress in the late stage of fruit ripening. PpaCu/Zn-SODs were the most abundant members in the PpaSOD gene family and they expressed steadily in peach fruit development and ripening. Low temperature (4 °C) postponed and suppressed the climacteric peaks of respiration and ethylene, significantly enhanced the activities of CAT and GPX, and up-regulated the expression of PpaCAT1 and PpaGPX6 in the late stage of fruit ripening. PpaCAT1 and PpaGPX6 were two key genes in alleviating oxidative stress in the late stage of fruit ripening. PMID:27208820

    Full Text Available Intervention group as a resource of Occupational Therapy is the main theme of this study. Herein we present an experience carried out in two universities in the areas of occupational therapy, pharmacy and medicine, more specifically in the field of gynecology regarding the care of climacteric woman. The first intervention occurred in 2004 with trainees of the occupational therapy course and medical school residents. However, the study was restarted in 2010 with expansion to the human resources and knowledge areas. The methodology was based on the transcripts of the remarks made after each group meeting, which was coordinated by the Occupational Therapy. Results showed that the intervention group process has helped participants in the understanding of this stage of life and has interfered in the changing of habits and attitudes, with great improvement in daily life organization. We concluded that the use of intervention group as a resource of Occupational Therapy and the liaison with other areas are of great importance because they enable the construction of a unique treatment plan for the group, given the contribution from each clinical area.

    Genetic solutions to postharvest crop loss can reduce cost and energy inputs while increasing food security, especially for banana (Musa acuminata), which is a significant component of worldwide food commerce. We have functionally characterized two banana E class (SEPALLATA3 [SEP3]) MADS box genes, MaMADS1 and MaMADS2, homologous to the tomato (Solanum lycopersicum) RIN-MADS ripening gene. Transgenic banana plants repressing either gene (via antisense or RNA interference [RNAi]) were created and exhibited specific ripening delay and extended shelf-life phenotypes, including delayed color development and softening. The delay in fruit ripening is associated with a delay in climacteric respiration and reduced synthesis of the ripening hormone ethylene; in the most severe repressed lines, no ethylene was produced and ripening was most delayed. Unlike tomato rin mutants, banana fruits of all transgenic repression lines responded to exogenous ethylene by ripening normally, likely due to incomplete transgene repression and/or compensation by other MADS box genes. Our results show that, although MADS box ripening gene necessity is conserved across diverse taxa (monocots to dicots), unlike tomato, banana ripening requires at least two necessary members of the SEPALLATA MADS box gene group, and either can serve as a target for ripening control. The utility of such genes as tools for ripening control is especially relevant in important parthenocarpic crops such as the vegetatively propagated and widely consumed Cavendish banana, where breeding options for trait improvement are severely limited.

    Zhaohui peaches (Prunus persica Batsch) were treated with 0 (CK), 1, 10 or 100 μmol L-1methyl jasmonate (MeJA) vapor at 20℃ for 24 h before stored at 0℃ for 35 d. The untreated fruits showed chilling injury (CI) symptoms after 4 wk of storage, as indicated by increased fruit firmness and reduced extractable juice, which is referred as leatheriness. Treatment with 1 and 10 μmol L-1 MeJA promoted normal ripening and softening, maintained higher levels of extractable juice, titratable acidity, pectinesterase (PE)and polygalacturonase (PG) activities, inhibited increases in fruit fresh weight loss, decay incidence, electrolyte leakage and MDA content, and improved color development, thereby preventing chilling injury symptoms development and maintaining edible quality. MeJA treatment also delayed the climacteric rise in respiratory rate, but promoted ethylene production during the later period of cold storage, suggesting that ethylene may involve in CI development of peaches. These results indicate that 1 and 10 μmol L-1 MeJA treatments could be used to reduce CI development and decay incidence in peaches.

    Full Text Available Abstract Background With the advent of high throughput genomic tools, it is now possible to undertake detailed molecular studies of individual species outside traditional model organisms. Combined with a good understanding of physiological processes, these tools allow researchers to explore natural diversity, giving a better understanding of biological mechanisms. Here a detailed study of fruit development from anthesis through to fruit senescence is presented for a non-model organism, kiwifruit, Actinidia chinensis ('Hort16A'. Results Consistent with previous studies, it was found that many aspects of fruit morphology, growth and development are similar to those of the model fruit tomato, except for a striking difference in fruit ripening progression. The early stages of fruit ripening occur as the fruit is still growing, and many ripening events are not associated with autocatalytic ethylene production (historically associated with respiratory climacteric. Autocatalytic ethylene is produced late in the ripening process as the fruit begins to senesce. Conclusion By aligning A. chinensis fruit development to a phenological scale, this study provides a reference framework for subsequent physiological and genomic studies, and will allow cross comparison across fruit species, leading to a greater understanding of the diversity of fruits found across the plant kingdom.

    We studied the serum estradiol and estrone levels in 146 peri and postmenopausal women, and in 38 women who had complained of various climacteric disturbance symptoms during daily hormone replacement therapy (HRT) with conjugated equine estrogen (CEE) 0.625 mg and medroxyprogesterone acetate (MPA) 2.5 mg. Serum estradiol and estrone were measured before treatment, and at 6 months, and after one year of the HRT therapy by HPLC-radioimmunoassay. In 146 peri and postmenopausal women, the serum level of estradiol was from 3 to 6pg/ml. The serum level of estradiol in 38 women after HRT significantly increased (p < 0.01) from 3.34 to 23.6 pg/ml at 6 months, and 21.5 pg/ml at 12 months. The serum level of estrone significantly increased (p < 0.01) from 26.6pg/ml to 156.7pg/ml at 6 months, and 137.2pg/ml at 12 month. These results are very useful for deciding on the doses of hormones and the expected serum estradiol level in HRT for Japanese women. PMID:7636337

    1984-09-01

    Fruit of soursop, Annona muricata L., showed increased CO(2) production 2 days after harvest, preceding the respiratory increase that coincided with autocatalytic ethylene evolution and other ripening phenomena. Experiments to alter gas exchange patterns of postharvest fruit parts and tissue cylinders had little success.The respiratory quotient of tissue discs was near unity throughout development. 2,4-Dinitrophenol uncoupled respiration more effectively than carbonylcyanide m-chlorophenylhydrazone; 0.4 millimolar KCN stimulated, 4 millimolar salicylhydroxamic acid slightly inhibited, and their combination strongly inhibited respiration, as did 10 millimolar NaN(3). Tricarboxylic acid cycle members and ascorbate were more effective substrates than sugars, but acetate and glutarate strongly inhibited.Disc respiration showed the same early peak as whole fruit respiration; this peak is thus an inherent characteristic of postharvest development and cannot be ascribed to differences between ovaries of the aggregatetype fruit. The capacity of the respiratory apparatus did not change during this preclimacteric peak, but the contents of rate-limiting malate and citrate increased after harvest.It is concluded that the preclimacteric rise in CO(2) evolution reflects increased mitochondrial respiration because of enhanced supply of carboxylates as a substrate, probably induced by detachment from the tree. The second rise corresponds with the respiration during ripening of other climacteric fruits.

    In banana, ethylene production for ripening is accompanied by a dramatic increase in 1-aminocyclopropane-1-carboxylate (ACC) content, transcript level of Musa acuminata ACC synthase 1 (MA-ACS1) and the enzymatic activity of ACC synthase 1 at the onset of the climacteric period. MA-ACS1 catalyses the conversion of -adenosyl-L-methionine (SAM) to ACC, the key regulatory step in ethylene biosynthesis. Multiple sequence alignments of 1-aminocyclopropane-1-carboxylate synthase (ACS) amino acid sequences based on database searches have indicated that MA-ACS1 is a highly conserved protein across the plant kingdom. This report describes an in silico analysis to provide the first important insightful information about the sequential, structural and phylogenetic characteristics of MA-ACS1. The three-dimensional structure of MA-ACS1, constructed based on homology modelling, in combination with the available data enabled a comparative mechanistic analysis of MA-ACS1 to explain the catalytic roles of the conserved and non-conserved active site residues. We have further demonstrated that, as in apple and tomato, banana-ACS1 (MA-ACS1) forms a homodimer and a complex with cofactor pyridoxal-5′-phosphate (PLP) and inhibitor aminoethoxyvinylglycine (AVG). We have also predicted that the residues from the PLP-binding pocket, essential for ligand binding, are mostly conserved across the MA-ACS1 structure and the competitive inhibitor AVG binds at a location adjacent to PLP.

    Full Text Available Mango (Mangifera indica L. is an important fruit of the world owing to its pleasant aroma and taste. In this investigation, the influence of gibberellic acid (GA3 at concentrations of 0, 50, 100 and 150 mg∙l-1 water sprayed 20 days before commercial harvest on postharvest behavior and quality of mango cv. ‘Himsagar’ was studied under ambient storage conditions. GA3 (100 and 150 mg∙l-1 delayed the onset of ripening and caused a reduction in respiration rate as compared to the untreated fruits and retained the total chlorophyll content of fruit peel. Pre-harvest spray of GA3 at 100 mg∙l-1 significantly delayed the onset of the climacteric rise of CO2 production, which depicted delayed ripening over control. The treated fruits also remained firmer and maintained the freshness during storage. Treatment with 100 mg∙l-1 GA3 could be a useful method to extend postharvest life and availability of mango with appreciable quality.

    Korean Panax ginseng C A Meyer is mainly used to maintain the homeostasis of the body, and the pharmacological efficacy of Korean ginseng identified by modern science includes improved brain function, pain-relieving effects, pre-ventive effects against tumors as well as anti-tumor activity, enhanced immune system function, anti-diabetic effects, enhanced liver function, adjusted blood pressure, anti-fatigue and anti-stress effects, improved climacteric disorder and sexual functions, as well as anti-oxidative and anti-aging effects. Further clini-cal studies of these pharmacological efficacies will continue to be carried out. Korean ginseng is found to have such main properties as ginsenoside, ployacety-lene, acid polysaccharide, anti-oxidative aromatic compound, and insulin-like acid peptides. The number of ginsenoside types contained in Korean ginseng (38 ginsenosides) is substantially more than that of ginsenoside types contained in American ginseng (19 ginsenosides). Furthermore, Korean ginseng has been identified to contain more main non-saponin compounds, phenol compounds, acid polysaccharides and polyethylene compounds than American ginseng and Sanchi ginseng.

    Full Text Available The fig fruit is a unique, climacteric, highly perishable subject to rapid physiological breakdown. Application of 1-methylcyclopropene (1-MCP was tested to delay ripening of black fig (Ficus carica L. cv. ‘Bursa Siyahi’ during storage over two growing seasons. Fruits were pre-cooled to 1 °C for 6 hours and afterwards treated with 500 or 1000 nl l-1 of 1-MCP for 24 hours. Treated fruits were stored for 10 days at 1 °C, 90-95% RH and then evaluated. 1-MCP treatments showed that ethylene production, respiration rate, weight loss and concentrations of glucose, fructose and total soluble solids (TSS were negatively correlated to the 1-MCP doses during cold storage (with the exception of TSS in the first year of experiment and respiration rate in the second year of the experiment. In contrast, pulp firmness and colour (ho during cold storage were positively correlated to the 1-MCP applied doses. Results of this study showed that although 1-methylcyclopropene applications slowed down fruit softening during the 10 days of storage, 1-methylcyclopropene appeared to have a relatively limited effect on slowing ripening of ‘Bursa Siyahi’ figs.

    Fruit ripening involves a series of changes in gene expression regulated by the phytohormone ethylene. AVOe3, a ripening-related gene in avocado fruit (Persea americana Mill. cv Hass), was characterized with regard to its ethylene-regulated expression. The AVOe3 mRNA and immunopositive protein were induced in mature fruit within 12 hours of propylene treatment. The AVOe3 mRNA levels reached a maximum 1 to 2 days before the ethylene climacteric, whereas the immunopositive protein continued to accumulate. RNA selected by the pAVOe3 cDNA clone encoded a polypeptide with molecular mass of 34 kilodaltons, corresponding to the molecular mass of the AVOe3 protein determined by immunoblots. The protein was soluble, remaining in solution at 100,000 gravity and eluted as a monomer on gel filtration. Because of its pattern of induction and relationship to an ethylene-related gene of tomato, the possible involvement of AVOe3 in ethylene biosynthesis is discussed.

    Full Text Available Guava is a fruit with high respiration rates and a very short shelf life. Since information on its respiration pattern is contradictory, the objective was to study the changes occurring in the fruit during ripening and to relate them to the respiration behavior of this fruit. Guavas were picked at the half-ripe stage and stored for 8 days at 22 ± 1 ºC and 78 ± 1% relative humidity. The analyses conducted were: peel and pulp coloration, firmness, total soluble solids (TSS, total titratable acidity (TTA, and ethylene production. According to the results, it was verified that the parameters analyzed apparently do not coincide and are ethylene-independent. There was an accentuated ethylene production during ripening, starting from the 4th day. The ethylene synthesis continued increasing up to the 8th day, when the fruits were already decomposing. It was observed that the firmness decreased sharply in the first three days of ripening, and the skin and pulp color changed during ripening. The TSS, total soluble solids, and the TTA, total titratable acidity, practically did not change during the ripening, even with the increased ethylene production. It can be concluded that guava is a fruit that presents characteristics of climacteric and non-climacteric fruits.A goiaba apresenta altas taxas de respiração e uma vida útil muito curta, e como as informações sobre o padrão respiratório são contraditórias, objetivou-se estudar mudanças ocorridas no fruto durante o amadurecimento e relacioná-las ao comportamento respiratório desses frutos.

    Hypoestrogenism is the primary etiologic factor for osteoporosis and related fractures, as well as for a number of clinical symptoms that can reduce the quality of life in postmenopausal women. Alternative to classical hormone replacement therapy (HRT) are needed for women that cannot or don't want to be treated with hormones. Selective estrogen receptor modulators (SERMs) are compounds that lack the steroid structure of estrogens, but interact with estrogen receptors (ERs) as agonists or antagonists depending on the target tissue. Tamoxifen, the first generation of SERMs, has been used for decades in the primary prevention and treatment of breast cancer. Tamoxifen exerts positive estrogenic effect on bone protecting bone mineral density (BMD). However, tamoxifen acts as agonist also on the endometrium, leading to an increased risk of endometrial hyperplasia and cancer. In addition, tamoxifen administration is associated with significantly increased risks of stroke, venous thromboembolism, including both deep-vein thrombosis and pulmonary emboli. Thus, these actions, in addition to the increased risk of and hot flushes, prevent the use of tamoxifen for the prevention of osteoporosis. Further generations of SERM, Raloxifene and bazedoxifene were developed for the prevention and treatment of postmenopausal osteoporosis and are now licensed for this indication. In addition. Raloxifene is as effective as tamoxifen in reducing the risk of invasive breast cancer. On the other hand, the available data indicate that Bazedoxifene exerts a greater anti-fracture activity than Raloxifene. At variance of tamoxifen, both raloxifene and bazedoxifene reduce the risk of endometrial hyperplasia and cancer. However, they are associated with a significant increase the risks of venous thromboembolic events. Although raloxifene and Bazedoxifene prevent postmenopausal osteoporosis, they have not been associated with reductions in climacteric symptoms, particularly hot flushes. In order

    Full Text Available The objective of this work was to evaluate the effects of KMnO4 on the extension of postharvest life of 'Sunrise Golden' papaya, stored under modified atmosphere and refrigeration. Fruit with up to 10% yellow peel were harvested in a commercial orchard in Linhares, state of Espírito Santo, Brazil. Sets of three fruit (unit mass of 289.9±18.5 g were wrapped in low-density polyethylene films (28 ¼m thick containing sachets of KMnO4 at 0, 0.5, 1, 1.5, and 2 g per bag. The bags were sealed and stored at 10.4±0.9°C and 90±5% relative humidity for 25 days. After this period, the fruit were removed from the bags and maintained at 21±0.8°C and 90±5% relative humidity until complete ripening. Four days after bag sealing, CO2 concentration stabilized in all treatments, and was higher in bags without KMnO4. In all treatments, fruit reached the climacteric respiratory peak on the third day after bag removal, coinciding with peel color index of 3.5. Increasing the KMnO4 dose reduced the losses in fruit fresh matter, consistency and pulp electrolyte leakage. Potassium permanganate was effective in maintaining the fruit at the pre-climacteric stage during the 25-day storage, and did not interfere with normal ripening after bag removal.O objetivo deste trabalho foi avaliar os efeitos do KMnO4 na extensão da vida pós-colheita da cultivar de mamão Sunrise Golden, armazenada em atmosfera modificada e refrigeração.

    Changes in characteristic aroma volatiles, levels of fatty acids as aroma precursors, and expression patterns of related genes, including lipoxygenase (LOX), hydroperoxide lyase (HPL), alcohol dehydrogenase (ADH), alcohol acyltransferase (AAT), and fatty acid desaturase (FAD), were studied in peach ( Prunus persica L. Batsch., cv. Yulu) fruit during postharvest ripening at 20 degrees C. Concentrations of n-hexanal, (E)-2-hexenal, (E)-2-hexenol, and (Z)-3-hexenol decreased, whereas the production of (Z)-3-hexenyl acetate, gamma-hexalactone, gamma-octalactone, gamma-decalactone, and delta-decalactone increased with fruit ripening. Lactones showed a clear pattern concomitant with the climacteric rise in ethylene production, with gamma-decalactone being the principal volatile compound at the late ripening stage. Of the LOX family genes, PpLOX2 and PpLOX3 had relatively high transcript levels initially followed by a decline with fruit ripening, while levels of PpLOX1 and PpLOX4 transcripts were upregulated by accumulated ethylene production. Expression of PpHPL1, PpADH1, PpADH2, and PpADH3 showed similar decreasing patterns during ripening. Expression levels of PpAAT1 showed a rapid increase during the first 2 days of postharvest ripening followed by a gradual decrease. Contents of polyunsaturated linoleic and linolenic acids increased, and saturated palmitic acid levels tended to decline as the fruit ripened. The increased levels of unsaturated fatty acids closely paralleled increasing expression of PpFAD1 and PpFAD2. The significance of gene expression changes in relation to aroma volatile production is discussed. PMID:20415420

    Full Text Available Introduction Olfaction is considered to be the ability to: perceive, conduct and recognize scents and odors. With its numerous connections to the limbic system and reticular formation, the olfactory system affects regulation of numerous vegetative functions, visceral functions and sexual behavior. Since estrogen and progesterone protect the olfactory function, changes in their levels in particular physiological states in women (in pregnancy and postmenopause exert an influence on the ability to feel and recognize smells. It has its role in creating emotions and adjustment of visceral and vegetative response to particular emotional states. Also, it represents the connection between higher cortical functions and the endocrine system. Material and methods Our investigation was performed at the Ear, Nose and Throat Clinic in Novi Sad. The research included 80 healthy women classified into 4 groups; 20 women aged between 20 and 30; 20 women in the first trimester of pregnancy aged between 20 and 30; 20 premenopausal women aged between 41 and 50; and 20 women at least 3 years in postmenopause, aged between 41 and 50. For our research we used an olfactometer and the Fortunato-Niccolini method. Results and discussion In pregnancy the thresholds of perception (TP and identification (TI of examined substances were slightly lower in comparison to nonpregnant women of the same ages, but without any statistical significance (p>0.05. In climacteric-postmenopausal women there was a significant decrease of olfactory ability in comparison to nonmenopausal women of the same ages (p<0.01. Conclusion All changes of the olfactory function in pregnancy are explained by mental changes of pregnant women as well as their hormonal status. Significant decrease of olfactory ability in postmenopause is explained by decline in sexual hormone levels.

    Computational analyses of molecular phenotypes traditionally aim at identifying biochemical components that exhibit differential expression under various scenarios (e.g. environmental and internal perturbations) in a single species. High-throughput metabolomics technologies allow the quantification of (relative) metabolite levels across developmental stages in different tissues, organs, and species. Novel methods for analyzing the resulting multiple data tables could reveal preserved dynamics of metabolic processes across species. The problem we address in this study is 2-fold. (1) We derive a single data table, referred to as a compromise, which captures information common to the investigated set of multiple tables containing data on different fruit development and ripening stages in three climacteric (i.e. peach [Prunus persica] and two tomato [Solanum lycopersicum] cultivars, Ailsa Craig and M82) and two nonclimacteric (i.e. strawberry [Fragaria × ananassa] and pepper [Capsicum chilense]) fruits; in addition, we demonstrate the power of the method to discern similarities and differences between multiple tables by analyzing publicly available metabolomics data from three tomato ripening mutants together with two tomato cultivars. (2) We identify the conserved dynamics of metabolic processes, reflected in the data profiles of the corresponding metabolites that contribute most to the determined compromise. Our analysis is based on an extension to principal component analysis, called STATIS, in combination with pathway overenrichment analysis. Based on publicly available metabolic profiles for the investigated species, we demonstrate that STATIS can be used to identify the metabolic processes whose behavior is similarly affected during fruit development and ripening. These findings ultimately provide insights into the pathways that are essential during fruit development and ripening across species.

    In this study, the effect of melatonin on the postharvest ripening and quality improvement of tomato fruit was carried out. The tomatoes were immersed in exogenous melatonin for 2h, and then the related physiological indicators and the expression of genes during post-harvest life were evaluated. Compared with control check (CK), the 50 µM melatonin treatment significantly increased lycopene levels by 5.8-fold. Meanwhile, the key genes involved in fruit colour development, including phytoene synthase1 (PSY1) and carotenoid isomerase (CRTISO), showed a 2-fold increase in expression levels. The rate of water loss from tomato fruit also increased 8.3%, and the expression of aquaporin genes, such as SlPIP12Q, SlPIPQ, SlPIP21Q, and SlPIP22, was up-regulated 2- to 3-fold under 50 µM melatonin treatment. In addition, 50 µM melatonin treatment enhanced fruit softening, increased water-soluble pectin by 22.5%, and decreased protopectin by 19.5%. The expression of the cell wall modifying proteins polygalacturonase (PG), pectin esterase1 (PE1), β-galactosidase (TBG4), and expansin1 (Exp1) was up-regulated under 50 µM melatonin treatment. Melatonin increased ethylene production by 27.1%, accelerated the climacteric phase, and influenced the ethylene signalling pathway. Alteration of ethylene production correlated with altered 1-aminocyclopropane-1-carboxylic acid (ACC) synthase (ACS4) expression. The expression of ethylene signal transduction-related genes such as NR, SlETR4, SlEIL1, SlEIL3, and SlERF2, was enhanced by 50 µM melatonin. The effect of melatonin on ethylene biosynthesis, ethylene perception, and ethylene signalling may contribute to fruit ripening and quality improvement in tomato. This research may promote the application of melatonin on postharvest ripening and quality improvement of tomato fruit as well as other horticultural productions in the future.

The effects of preservation Of different concentrations of phytic acid in the coating treatment on tomatoes were studied. The results showed that phytic acid could inhabit the peak time of respiratory rate of the climacteric in ripening tomato fruit, reduce the respiration rate and could keep the hardness, soluble solids, titratable acid and vitamin C of tomoto. Meanwhile,it could decrease the water evaporation and weightlessness rate of fruit. The best concentration of phytic acid that coated tomotoes fruit in preservation was 0.10%.

    Although great progress has been made towards understanding the role of abscisic acid (ABA) and sucrose in fruit ripening, the mechanisms underlying the ABA and sucrose signalling pathways remain elusive. In this study, transcription factor ABA-stress-ripening (ASR), which is involved in the transduction of ABA and sucrose signalling pathways, was isolated and analysed in the nonclimacteric fruit, strawberry and the climacteric fruit, tomato. We have identified four ASR isoforms in tomato and one in strawberry. All ASR sequences contained the ABA stress- and ripening-induced proteins and water-deficit stress-induced proteins (ABA/WDS) domain and all ASR transcripts showed increased expression during fruit development. The expression of the ASR gene was influenced not only by sucrose and ABA, but also by jasmonic acid (JA) and indole-3-acetic acid (IAA), and these four factors were correlated with each other during fruit development. ASR bound the hexose transporter (HT) promoter, which contained a sugar box that activated downstream gene expression. Overexpression of the ASR gene promoted fruit softening and ripening, whereas RNA interference delayed fruit ripening, as well as affected fruit physiological changes. Change in ASR gene expression influenced the expression of several ripening-related genes such as CHS, CHI, F3H, DFR, ANS, UFGT, PG, PL, EXP1/2, XET16, Cel1/2 and PME. Taken together, this study may provide new evidence on the important role of ASR in cross-signalling between ABA and sucrose to regulate tomato and strawberry fruit ripening. The findings of this study also provide new insights into the regulatory mechanism underlying fruit development.

    The ripening hormone, ethylene is known to initiate, modulate and co-ordinate the expression of various genes involved in the ripening process. The burst in ethylene production is the key event for the onset of ripening in climacteric fruits, including tomatoes. Therefore ethylene is held accountable for the tons of post-harvest losses due to over-ripening and subsequently resulting in fruit rotting. In the present investigation, delayed ripening tomatoes were generated by silencing three homologs of 1-aminocyclopropane-1-carboxylate (ACC) synthase (ACS) gene during the course of ripening using RNAi technology. The chimeric RNAi-ACS construct designed to target ACS homologs, effectively repressed the ethylene production in tomato fruits. Fruits from such lines exhibited delayed ripening and extended shelf life for ∼45 days, with improved juice quality. The ethylene suppression brought about compositional changes in these fruits by enhancing polyamine (PA) levels. Further, decreased levels of ethylene in RNAi-ACS fruits has led to the altered levels of various ripening-specific transcripts, especially the up-regulation of PA biosynthesis and ascorbic acid (AsA) metabolism genes and down-regulation of cell wall hydrolyzing enzyme genes. These results suggest that the down-regulation of ACS homologs using RNAi can be an effective approach for obtaining delayed ripening with longer shelf life and an enhanced processing quality of tomato fruits. Also, the chimeric gene fusion can be used as an effective design for simultaneous silencing of more than one gene. These observations would be useful in better understanding of the ethylene and PA signaling during fruit ripening and molecular mechanisms underlying the interaction of these two molecules in affecting fruit quality traits.

    Ethylene production by 10 or 20 m2 stands of wheat, soybean, lettuce, potato, and tomato was monitored throughout growth and development in an atmospherically closed plant chamber. Chamber ethylene levels varied among species and rose during periods of canopy expansion and rapid growth for all species. Following this, ethylene levels either declined during seed fill and maturation for wheat and soybean, or remained relatively constant for potato and tomato (during flowering and early fruit development). Lettuce plants were harvested during rapid growth and peak ethylene production. Chamber ethylene levels increased rapidly during tomato ripening, reaching concentrations about 10 times that measured during vegetative growth. The highest ethylene production rates during vegetative growth ranged from 1.6 to 2.5 nmol m-2 d-1 during rapid growth of lettuce and wheat stands, or about 0.3 to 0.5 nmol g-1 fresh weight per hour. Estimates of stand ethylene production during tomato ripening showed that rates reached 43 nmol m-2 d-1 in one study and 93 nmol m-2 d-1 in a second study with higher lighting, or about 50x that of the rate during vegetative growth of tomato. In a related test with potato, the photoperiod was extended from 12 to 24 hours (continuous light) at 58 days after planting (to increase tuber yield), but this change in the environment caused a sharp increase in ethylene production from the basal rate of 0.4 to 6.2 nmol m-2 d-1. Following this, the photoperiod was changed back to 12 h at 61 days and ethylene levels decreased. The results suggest three separate categories of ethylene production were observed with whole stands of plants: 1) production during rapid vegetative growth, 2) production during climacteric fruit ripening, and 3) production from environmental stress.

    The banana (Musa spp.) is a typical climacteric fruit of high economic importance. The development of bananas from maturing to ripening is characterized by increased ethylene production accompanied by a respiration burst. To elucidate the signal transduction pathway involved in the ethylene regulation of banana ripening, a gene homologous to Arabidopsis CTR1 (constitutive triple response 1) was isolated from Musa spp. (Hsien Jin Chiao, AAA group) and designated as MhCTR1. MhCTR1 spans 11.5 kilobases and consists of 15 exons and 14 introns with consensus GT-AG nucleotides situated at their boundaries. MhCTR1 encodes a polypeptide of 805 amino acid residues with a calculated molecular weight of 88.6 kDa. The deduced amino acid sequence of MhCTR1 demonstrates 55%, 56% and 55% homology to AtCTR1, RhCTR1, and LeCTR1, respectively. MhCTR1 is expressed mostly in the mature green pulp and root organs. During fruit development MhCTR1 expression increases just before ethylene production rises. Moreover, MhCTR1 expression was detected mainly in the pulps at ripening stage 3, and correlated with the onset of peel yellowing, while MhCTR1 was constitutively expressed in the peels. MhCTR1 expression could be induced by ethylene treatment (0.01 μL L(-1)), and MhCTR1 expression decreased in both peel and pulp 24 h after treatment. Overall, changes observed in MhCTR1 expression in the pulp closely related to the regulation of the banana ripening process.

    Date palm (Phoenix dactylifera) is an economically important fruit tree in the Middle East and North Africa and is characterized by large cultivar diversity, making it a good model for studies on fruit development and other important traits. Here in gel comparative proteomics combined with tandem mass spectrometry were used to study date fruit development and ripening. Total proteins were extracted using a phenol-based protocol. A total of 189 protein spots were differentially regulated (p≤0.05). The identified proteins were classified into 14 functional categories. The categories with the most proteins were ‘disease and defense’ (16.5%) and ‘metabolism’ (15.4%). Twenty-nine proteins have not previously been identified in other fleshy fruits and 64 showed contrasting expression patterns in other fruits. Abundance of most proteins with a role in abiotic stress responses increased during ripening with the exception of heat shock proteins. Proteins with a role in anthocyanin biosynthesis, glycolysis, tricarboxylic acid cycle and cell wall degradation were upregulated particularly from the onset of ripening and during ripening. In contrast, expression of pentose phosphate- and photosynthesis-related proteins decreased during fruit maturation. Although date palm is considered a climacteric species, the analysis revealed downregulation of two enzymes involved in ethylene biosynthesis, suggesting an ethylene-independent ripening of ‘Barhi’ fruits. In summary, this proteomics study provides insights into physiological processes during date fruit development and ripening at the systems level and offers a reference proteome for the study of regulatory mechanisms that can inform molecular and biotechnological approaches to further improvements of horticultural traits including fruit quality and yield.

    Litchi (Litchi chinensis) is a non-climacteric tropical fruit. The fruit has a short shelf-life making its marketing difficult. Physical, biochemical, microbiological, and organoleptic properties of two major commercially grown Indian cultivars of litchi, 'Shahi' and 'China' were studied. The effect of gamma radiation processing and low temperature storage on the above parameters was evaluated to standardize the optimal process parameters for shelf-life extension of litchi. Physical and biochemical parameters analyzed included weight, moisture, pH, titratable acidity, texture, color, total and reducing sugar, total soluble solids, vitamin C, and flavonoid content. Weight, moisture content, and pH in the fresh fruit ranged between 21-26 g, 74-77%, and 3.7-4.4, respectively, whereas, total and reducing sugar ranged 10-15, and 10-13 g%, respectively. In 'Shahi' vitamin C content was found to be around 17-19 mg%, whereas, in 'China' it was 22-28 mg%. Flavonoid content was in the range of 26-34 {mu}g catechin equivalents/g of fresh fruit. Total surface and internal bacterial load was around 4 and 3 log cfu/g, respectively. Surface yeast-mold count (YMC) was {approx}3 log cfu/g whereas internal YMC was {approx}2 log cfu/g. Radiation treatment reduced microbial load in a dose dependent manner. Treatment at 0.5 kGy did not significantly affect the quality parameters of the fruit. Treated fruits retained the 'good' organoleptic rating during storage. Thus, radiation treatment (0.5 kGy) in combination with low temperature (4 {sup o}C) storage achieved a shelf-life of 28 days for litchi fruit.

    Full Text Available Pitaya (Hylocereus undatus is an exotic non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage. Our objectives were to determine the best combination of storage temperature and use of perforated plastic bags to maintain the postharvest quality of the fruit. Fruits were stored at 5, 7, or 10 ºC with and without a perforated plastic bag for 20 days, followed by five days at 20 ºC without the bag for shelf-life determination. Storage at 5 ºC, followed by 7 ºC maintained better visual appearance of the pitaya fruit after 20 days, by reducing decay incidence and severity, and maintaining greener bracts compared with fruit stored at 10 ºC. Pitaya fruit stored at 5 ºC without a perforated plastic bag showed no decay after storage and shelf-life. In general, higher temperatures and the use of a perforated plastic bag increased decay incidence, as well as decay severity after storage and shelf-life conditions. At all temperatures, fruit stored in a perforated plastic bag had lower weight loss during storage. After shelf-life, weight loss was highest in fruit stored at higher temperatures. Storage of fruits at 5 ºC resulted in minor chilling injury symptoms in the outer flesh tissue, close to the peel. Storage at 5 ºC without a perforated plastic bag was the best condition to maintain the postharvest quality of the pitaya fruit.

    CBF/DREB1 is a group of transcription factors that are mainly involved in abiotic stress tolerance in plants. They belong to the AP2/ERF superfamily of plant-specific transcription factors. A gene encoding a new member of this group was isolated from ripening oil palm fruit and designated as EgCBF3. The oil palm fruit demonstrates the characteristics of a climacteric fruit like tomato, in which ethylene has a major impact on the ripening process. A transgenic approach was used for functional characterization of the EgCBF3, using tomato as the model plant. The effects of ectopic expression of EgCBF3 were analyzed based on expression profiling of the ethylene biosynthesis-related genes, anti-freeze proteins (AFPs), abiotic stress tolerance and plant growth and development. The EgCBF3 tomatoes demonstrated altered phenotypes compared to the wild type tomatoes. Delayed leaf senescence and flowering, increased chlorophyll content and abnormal flowering were the consequences of overexpression of EgCBF3 in the transgenic tomatoes. The EgCBF3 tomatoes demonstrated enhanced abiotic stress tolerance under in vitro conditions. Further, transcript levels of ethylene biosynthesis-related genes, including three SlACSs and two SlACOs, were altered in the transgenic plants' leaves and roots compared to that in the wild type tomato plant. Among the eight AFPs studied in the wounded leaves of the EgCBF3 tomato plants, transcript levels of SlOSM-L, SlNP24, SlPR5L and SlTSRF1 decreased, while expression of the other four, SlCHI3, SlPR1, SlPR-P2 and SlLAP2, were up-regulated. These findings indicate the possible functions of EgCBF3 in plant growth and development as a regulator of ethylene biosynthesis-related and AFP genes, and as a stimulator of abiotic stress tolerance.

    Banana is a highly perishable climacteric fruit. In order to ensure fast and homogeneous ripening that will make its processing and commercialization easier, it is usually treated by climatization. On the other hand, irradiation is an interesting physical process capable of delaying ripening and extending the shelf life of fruits. This work investigated the competing effects of irradiation followed by climatization on the quality of 'Prata' banana (Musa acuminata x Musa balbisiana, AAB). All fruits were harvested in the preclimacteric stage, rinsed and stored at 27 deg C after being submitted to five different treatments. After hygienization, four out of five samples were exposed to gamma-ray at doses of 0.25 and 0.50 kGy. The unirradiated fruits were left for control and half of the irradiated samples were then climatized by exposure to CaC{sub 2}. Measurements of fresh mass loss, total soluble solids, peel coloration and disease index were performed on five different dates for up to nine days in order to monitor quality and the degree of ripening. It was found that high temperatures prevailing during climatization and storage accelerated maturation in all fruits in spite of the use of irradiation, with the control becoming ripe in 3 days only. In addition, based on the consistent results from the experiments performed, it can be concluded that irradiation at the doses tested was unable to overcome the maturation effects produced by climatization. However, the sole use of irradiation with 0.25 kGy yielded the lowest figures for fresh mass loss and disease index in the samples, thus becoming the most attractive among the treatments tested.

    The effects of 1-MCP treatment on postharvest physiological characteristics and storage quality of Fuji apple in the different storage facilities (large constant temperature cold storage, small assembled type constant temperature storage, improved cave and traditional cave) were investigated. The results showed that, Fuji apple was respiration climacteric fruit, under four different storage facilities condition, the treatment of 1 -MCP could obviously reduce the respiration rate and ethylene release rate, keep the fruit firmness and titratable acid content better, and the storage facilities better, the effect of 1-MCP treatment was more obvious. But the fruit soluble solid content reduced, it because of 1-MCP treatment delayed fruit ripening and the relatively maturity was low.%以富士苹果为试材,研究了不同贮藏设施(大型恒温冷库、小型组装式恒温贮藏库、改造土窑洞、传统土窑洞)条件下1-MCP处理对富士苹果采后生理特性和贮藏品质的影响.结果表明,富士苹果属呼吸跃变型果实,在四种不同贮藏设施条件下,1-MCP处理均可明显降低贮藏期间果实的呼吸速率和乙烯释放速率,较好地保持果实硬度和可滴定酸含量,且贮藏设施条件越好,1-MCP的处理效果越明显.但果实的可溶性固形物含量有所降低,可能是1-MCP处理延缓了果实的后熟、成熟度较低的缘故.

    Full Text Available Watermelon [Citrullus lanatus (Thunb. Matsum. & Nakai] is an important vegetable crop world-wide. Watermelon fruit quality is a complex trait determined by various factors such as sugar content, flesh color and flesh texture. Fruit quality and developmental process of cultivated and wild watermelon are highly different. To systematically understand the molecular basis of these differences, we compared transcriptome profiles of fruit tissues of cultivated watermelon 97103 and wild watermelon PI296341-FR. We identified 2,452, 826 and 322 differentially expressed genes in cultivated flesh, cultivated mesocarp and wild flesh, respectively, during fruit development. Gene ontology enrichment analysis of these genes indicated that biological processes and metabolic pathways related to fruit quality such as sweetness and flavor were significantly changed only in the flesh of 97103 during fruit development, while those related to abiotic stress response were changed mainly in the flesh of PI296341-FR. Our comparative transcriptome profiling analysis identified critical genes potentially involved in controlling fruit quality traits including α-galactosidase, invertase, UDP-galactose/glucose pyrophosphorylase and sugar transporter genes involved in the determination of fruit sugar content, phytoene synthase, β-carotene hydroxylase, 9-cis-epoxycarotenoid dioxygenase and carotenoid cleavage dioxygenase genes involved in carotenoid metabolism, and 4-coumarate:coenzyme A ligase, cellulose synthase, pectinesterase, pectinesterase inhibitor, polygalacturonase inhibitor and α-mannosidase genes involved in the regulation of flesh texture. In addition, we found that genes in the ethylene biosynthesis and signaling pathway including ACC oxidase, ethylene receptor and ethylene responsive factor showed highly ripening-associated expression patterns, indicating a possible role of ethylene in fruit development and ripening of watermelon, a non-climacteric fruit.

    Citrus fruits possess unique aromas rarely found in other fruit species. While fruit flavor is composed of complex combinations of soluble and volatile compounds, several low-abundance sesquiterpenes, such as valencene, nootkatone, alpha-sinensal, and beta-sinensal, stand out in citrus as important flavor and aroma compounds. The profile of terpenoid volatiles in various citrus species and their importance as aroma compounds have been studied in detail, but much is still lacking in our understanding of the physiological, biochemical, and genetic regulation of their production. Here, we report on the isolation, functional expression, and developmental regulation of Cstps1, a sesquiterpene synthase-encoding gene, involved in citrus aroma formation. The recombinant enzyme encoded by Cstps1 was shown to convert farnesyl diphosphate to a single sesquiterpene product identified as valencene by gas chromatography-mass spectrometry (GC-MS). Phylogenetic analysis of plant terpene synthase genes localized Cstps1 to the group of angiosperm sesquiterpene synthases. Within this group, Cstps1 belongs to a subgroup of citrus sesquiterpene synthases. Cstps1 was found to be developmentally regulated: transcript was found to accumulate only towards fruit maturation, corresponding well with the timing of valencene accumulation in fruit. Although citrus fruits are non-climacteric, valencene accumulation and Cstps1 expression were found to be responsive to ethylene, providing further evidence for the role of ethylene in the final stages of citrus fruit ripening. Isolation of the gene encoding valencene synthase provides a tool for an in-depth study of the regulation of aroma compound biosynthesis in citrus and for metabolic engineering for fruit flavor characteristics.

    Concerns pertaining to the risk of estrogen exposure through HT have prompted an increase in the use of natural alternatives. Phytoestrogens may provide postmenopausal women with a practical alternative and many women have already begun to utilize phytoestrogen supplements. However, research regarding the efficacy of phytoestrogens as a hormone therapy alternative has been previously pessimistic or questionable at best. This review scrutinizes the most current research regarding the efficacy of three types of phytoestrogens, isoflavones, lignans and coumestans, and their specific effect on the reduction of climacteric symptoms, specifically vasomotor symptoms, vaginal atrophy, insomnia and osteoporosis. A discussion of the research pertaining to the relative safety of each phytoestrogen in terms of breast and endometrial health is also included. Overall, current research demonstrates that phytoestrogens are effective in reducing the intensity of hot flushes, and some phytoestrogen combinations result in a decreased frequency. Certain phytoestrogens have also been shown to decrease vaginal atrophy, improve sleep and cognition, and positively affect bone health. Even though initial research was generally unconvincing, the more recent evidence reviewed here is rather positive. In terms of safety and reports of adverse reactions, trials have not shown an increase in breast cancer risk or increase in endometrial hyperplasia following phytoestrogen use, but trials explicitly designed to find neoplasia have not been reported. Moreover, unlike hormone therapy, lignans may not increase clotting risk in postmenopausal women, thus supplements may serve as a treatment option for patients who have contraindications to hormone therapy. Phytoestrogens may provide a safe and partially effective alternative to HT. However, because research regarding phytoestrogens is relatively new, pharmaco-vigilence is still required, as these products are not yet FDA-approved. This article is

    Sweet cherry is a non-climacteric fruit and its ripening is regulated by abscisic acid (ABA) during fruit development. In this study, four cDNAs (PacCYP707A1–4) encoding 8′-hydroxylase, a key enzyme in the oxidative catabolism of ABA, were identified in sweet cherry fruits using tobacco rattle virus-induced gene silencing (VIGS) and particle bombardment approaches. Quantitative real-time PCR confirmed significant down-regulation of target gene transcripts in VIGS-treated cherry fruits. In PacCYP707A2-RNAi-treated fruits, ripening and fruit colouring were promoted relative to control fruits, and both ABA accumulation and PacNCED1 transcript levels were up-regulated by 140%. Silencing of PacCYP707A2 by VIGS significantly altered the transcripts of both ABA-responsive and ripening-related genes, including the ABA metabolism-associated genes NCED and CYP707A, the anthocyanin synthesis genes PacCHS, PacCHI, PacF3H, PacDFR, PacANS, and PacUFGT, the ethylene biosynthesis gene PacACO1, and the transcription factor PacMYBA. The promoter of PacMYBA responded more strongly to PacCYP707A2-RNAi-treated fruits than to PacCYP707A1-RNAi-treated fruits. By contrast, silencing of PacCYP707A1 stimulated a slight increase in fruit colouring and enhanced resistance to dehydration stress compared with control fruits. These results suggest that PacCYP707A2 is a key regulator of ABA catabolism that functions as a negative regulator of fruit ripening, while PacCYP707A1 regulates ABA content in response to dehydration during fruit development.

    Although great progress has been made towards understanding the role of abscisic acid (ABA) and sucrose in fruit ripening, the mechanisms underlying the ABA and sucrose signalling pathways remain elusive. In this study, transcription factor ABA-stress-ripening (ASR), which is involved in the transduction of ABA and sucrose signalling pathways, was isolated and analysed in the nonclimacteric fruit, strawberry and the climacteric fruit, tomato. We have identified four ASR isoforms in tomato and one in strawberry. All ASR sequences contained the ABA stress- and ripening-induced proteins and water-deficit stress-induced proteins (ABA/WDS) domain and all ASR transcripts showed increased expression during fruit development. The expression of the ASR gene was influenced not only by sucrose and ABA, but also by jasmonic acid (JA) and indole-3-acetic acid (IAA), and these four factors were correlated with each other during fruit development. ASR bound the hexose transporter (HT) promoter, which contained a sugar box that activated downstream gene expression. Overexpression of the ASR gene promoted fruit softening and ripening, whereas RNA interference delayed fruit ripening, as well as affected fruit physiological changes. Change in ASR gene expression influenced the expression of several ripening-related genes such as CHS, CHI, F3H, DFR, ANS, UFGT, PG, PL, EXP1/2, XET16, Cel1/2 and PME. Taken together, this study may provide new evidence on the important role of ASR in cross-signalling between ABA and sucrose to regulate tomato and strawberry fruit ripening. The findings of this study also provide new insights into the regulatory mechanism underlying fruit development. PMID:27005823

  5. Chemical aspects of irradiated mangoes

    International Nuclear Information System (INIS)

    Mango is an important and very popular tropical fruit. Because of its short shelf life, however, its use is restricted to the areas of production. Since mango is a climacteric fruit, it is possible to extend its shelf life by delaying the ripening process and senescence by irradiation. The ripening process is very complex: it appears that the radiation-induced delay in ripening may be mediated through the inhibition of the enzyme(s) involved in ethylene production. The dose required for shelf-life extension is ≤1.5 kGy. Higher doses can lead to scalding, flesh darkening and development of hollow pockets. This review focuses on the chemical aspects of radiation-induced shelf-life extension of mangoes. At the low irradiation doses required for this shelf-life extension (≤1.5 kGy), the chemical effects are negligible. Irradiation does not affect the carotenoid levels, and has only a minor effect on the vitamin C level in a few mango varieties. No significant differences in the free and total (hydrolyzed) amino acids, or the protein content of Kent mangoes, have been detected between irradiated and unirradiated samples. During ripening of the mangoes the reducing sugar and the total sugar levels increase, but in the majority of the mango varieties these levels remain very similar in irradiated and unirradiated samples. There are some differences in the volatile compounds between irradiated and unirradiated Kent mangoes; however, these differences have no apparent effect on the taste and flavor of the irradiated mangoes

    Unlike the typical climacteric fruits,persimmons (Diospyros kaki Thunb.) produce higher levels of ethylene when they are detached from trees at a younger stage.In order to obtain detailed information on the role of abscisic acid (ABA) in ripening,we cloned the DKNCED1,DKACS2,and DKAC01 genes from the calyx.Water loss was first noted in the calyx lobe,and DKNCED1 was highly expressed 1 d after the fruits were detached,coinciding with an increase in the ABA content.Then,the DKACS2 and DKAC01 genes were expressed after some delay.In the calyx,the ABA peak was observed 2 d after the fruits were harvested,and this peak preceded the ethylene peak observed on day 3.The fruit firmness rapidly decreased on day 4,and the fruits softened completely 6 d after they were harvested.The increases in the expressions of ABA,ethylene,and the genes in the calyxes occurred earlier than the corresponding increases in the pulp,although the 3 increases occurred on different days.Exogenous ABA treatment increased ABA concentration,induced expression of both ACS and ACO,and promoted ethylene synthesis and young-fruit softening;by contrast,treatment with NDGA inhibited the gene expressions and ethylene synthesis and delayed young-fruit softening.These results indicate that ethylene biosynthesis in the detached young persimmon fruits is initially triggered by ABA,which is induced by water loss in the calyx,through the induction of DKACS2 and DKAC01 expressions.The ethylene produced in the calyx subsequently diffuses into the pulp tissue,where it induces autocatalytic ethylene biosynthesis,resulting in an abrupt increase in ethylene production.

    The arrayan berry (Luma apiculata) is a native fruit from South America that belongs to the Myrtaceae family. To elucidate and characterize the developmental process and the potential health benefits of this edible fruit, quality and physiological parameters, along with antioxidant capacity, were evaluated during four clearly defined developmental stages of the fruit in two seasons. Fruit firmness slowly decreases during fruit development, whereas the solid soluble content/titratable acidity ratio (SSC/TA) increases significantly in the final stages of development. The measurement of low respiration rates and low ethylene production during growth and ripening suggested that the arrayan berry should be classified as a non-climacteric fruit. Arrayan berries show a significant increase in their antioxidant capacity from small green to black ripe fruit. FRAP and TEAC assays showed high correlations with total polyphenolic content (TPC) during ripening and high antioxidant capacity at all fruit stages, showing greater values in ripe fruit (FRAP: 24 ± 2 and 28 ± 3 μM FeSO4/gFW; TEAC: 18 ± 2 and 20 ± 1 Eq. Trolox/gFW for each season, respectively) than those observed in the blueberry (FRAP: 10 ± 2 and 19 ± 3 μM FeSO4/gFW; TEAC: 10 ± 2 and 17 ± 3). In addition, bioactive assays using ripe fruit extracts show presence of flavonol and anthocyanins, a high ORAC value (62,500 ± 7000 μmol/gDW) and a concentration-dependent vascular protection under high glucose conditions. The results obtained show that these endemic berry fruits have a promising potential as functional food.

    Compared to other melon types, oriental sweet melon (Cucumis melo var. makuwa Makino) is quite a different species with a shorter shelf-life due to its typical climacteric behavior and thin pericarp. The purpose of this experiment is to explore the effects of co-treatment of enhanced freshness formulation (EFF) and 1-methylcyclopropene (1-MCP) on physiological changes and the content of aroma volatile compounds introduced by them of two oriental sweet melon cultivars (Yumeiren and Tianbao) during storage. The melons were stored in incubators with temperature of 15°C and a relative humidity of 85%for 24 d during which fruit quality and related physiological index were measured. Compared to the control, both treatments delayed fruit weight loss rate and kept the fruit ifrmness, water content and soluble solids content. Ascorbate peroxidase (APX) and phenylalanine ammonia lyase (PAL) activities showed lfuctuations in treated melons, while lipoxygenase (LOX) activity (P<0.01) and malondialdehyde (MDA) content (P<0.05) decreased compared to control. During the early stage of storage, alcohols and aldehydes were the main volatile compounds, and esters gradually increased during storage. Of all the esters, acetic esters were the main components, followed by oxalic acid esters and other esters. The total content of aroma volatile compounds, esters, alcohols and aldehydes of co-treated melons were all higher than those of 1-MCP treated and control melons. In addition, the aroma volatile peak of co-treated melons occurred later than that of 1-MCP treated and control melons. In summary, co-treatment of EFF and 1-MCP was more beneifcial than 1-MCP treatment to delay ripening and senescence, maintain fruit quality, enhance shelf-life and improve levels of aroma volatile compounds.

To elucidate and characterize the developmental process and the potential health benefits of this edible fruit, quality and physiological parameters, along with antioxidant capacity, were evaluated during four clearly defined developmental stages of the fruit in two seasons. Fruit firmness slowly decreases during fruit development, whereas the solid soluble content/titratable acidity ratio (SSC/TA) increases significantly in the final stages of development. The measurement of low respiration rates and low ethylene production during growth and ripening suggested that the arrayan berry should be classified as a non-climacteric fruit. Arrayan berries show a significant increase in their antioxidant capacity from small green to black ripe fruit. FRAP and TEAC assays showed high correlations with total polyphenolic content (TPC) during ripening and high antioxidant capacity at all fruit stages, showing greater values in ripe fruit (FRAP: 24 ± 2 and 28 ± 3 μM FeSO4/gFW; TEAC: 18 ± 2 and 20 ± 1 Eq. Trolox/gFW for each season, respectively) than those observed in the blueberry (FRAP: 10 ± 2 and 19 ± 3 μM FeSO4/gFW; TEAC: 10 ± 2 and 17 ± 3). In addition, bioactive assays using ripe fruit extracts show presence of flavonol and anthocyanins, a high ORAC value (62,500 ± 7000 μmol/gDW) and a concentration-dependent vascular protection under high glucose conditions. The results obtained show that these endemic berry fruits have a promising potential as functional food. PMID:26593612

    Full Text Available The onset of menopause is unique to every woman with varying symptoms which have implications on health and well-being. This study evaluated the perception, knowledge and beliefs about menopause and the prevalence of climacteric symptoms. The study was a cross-sectional survey of 280 menopausal women aged 45 years and older in the Accra Metropolis of the Greater Accra Region of Ghana. Data on socio-demographic characteristics, knowledge, beliefs and experience of menopausal symptoms were collected using a semi-structured questionnaire. Anthropometric data on weight, height, % body fat and MUAC were also taken. All data were analyzed using SPSS version 16.0 and presented as means and frequencies. Predictors of menopausal symptoms were determined by logistic regression. The mean age of onset of menopause was (48±2.9 years with 98.2% having some knowledge of the signs and symptoms of menopause. The most frequently reported menopausal symptoms by the women were: night sweats (83.2%, hot flashes (76.4%, mood swings (72.5% and vaginal dryness (71.4%. The significant predictors for the occurrence of the most common symptoms reported were: age at onset of menstruation, age of start of menopause, body weight and % body fat. There was a decreased risk of experiencing symptoms such as night sweats, mood swings and vaginal dryness as age at menopause increased. Menopausal transition was determined by both vasomotor and urogenital symptoms. Counseling and support are needed to enable women manage the symptoms better. Most women have heard of and know what menopause is.

  13. Reducing ethylene levels along the food supply chain: a key to reducing food waste?

    Excessive waste along the food supply chain of 71 (UK, Netherlands) to 82 (Germany) kg per head per year sparked widespread criticism of the agricultural food business and provides a great challenge and task for all its players and stakeholders. Origins of this food waste include private households, restaurants and canteens, as well as supermarkets, and indicate that 59-65% of this food waste can be avoided. Since ∼50% of the food waste is fruit and vegetables, monitoring and control of their natural ripening gas - ethylene - is suggested here as one possible key to reducing food waste. Ethylene accelerates ripening of climacteric fruits, and accumulation of ethylene in the supply chain can lead to fruit decay and waste. While ethylene was determined using a stationary gas chromatograph with gas cylinders, the new generation of portable sensor-based instruments now enables continuous in situ determination of ethylene along the food chain, a prerequisite to managing and maintaining the quality and ripeness of fruits and identifying hot spots of ethylene accumulation along the supply chain. Ethylene levels were measured in a first trial, along the supply chain of apple fruit from harvest to the consumer, and ranged from 10 ppb in the CA fruit store with an ethylene scrubber, 70 ppb in the fruit bin, to 500 ppb on the sorting belt in the grading facility, to ppm levels in perforated plastic bags of apples. This paper also takes into account exogenous ethylene originating from sources other than the fruit itself. Countermeasures are discussed, such as the potential of breeding for low-ethylene fruit, applications of ethylene inhibitors (e.g. 1-MCP) and absorber strips (e.g. 'It's Fresh', Ryan'), packages (e.g. 'Peakfresh'), both at the wholesale and retail level, vents and cooling for the supply chain, sale of class II produce ('Wunderlinge'), collection (rather than waste) of produce on the 'sell by' date ('Die Tafel') and whole crop purchase (WCP) to aid reducing

    Strawberry is a non-climacteric fruit with a very short postharvest shelf-life. Loss of quality in this fruit is mostly due to its relatively high metabolic activity and sensitivity to fungal decay, meanly grey mold (Botrytis cinerea). In this study, the ability of gelatin coatings containing cellulose nanocrystals (CNC) to extend the shelf-life of strawberry fruit (Fragaria ananassa) over 8 days were studied. The filmogenic solution was obtained by the hydration of 5 g of gelatin (GEL) in 100 mL of distillated water containing different amounts of CNC dispersion (10 mg CNC/g of GEL or 50 mg of CNC/g of GEL) for 1 hour at room temperature. After this period, the solution was heated to 70 °C and maintained at this temperature for 10 minutes. The plasticizer (glycerol) (10g/100g of the GEL) was then added with constant, gentle stirring in order to avoid forming air bubbles and also to avoid gelatin denaturation until complete homogenization. Strawberries (purchased at the local market) were immersed in the filmogenic solution for 1 minute and after coated were dried at 15 °C by 24 hours. The strawberries were then kept under refrigeration and characterized in terms of their properties (weight loss, ascorbic acid content, titratable acidity, water content). The results have shown that samples covered with GEL/CNC had a significant improvement in its shelf- life. For instance, for the control sample (without coating) the weight loss after 8 days of storage was around 65%, while covered samples loss in the range of 31-36%. Edible coating was also effective in the retention of ascorbic acid (AA) in the strawberries, while control sample presented a fast decay in the AA content, covered samples showed a slow decay in the AA concentration. Moreover, the use of GEL/CNC edible coating had an antimicrobial effect in the fruits.

    CBF/DREB1 is a group of transcription factors that are mainly involved in abiotic stress tolerance in plants. They belong to the AP2/ERF superfamily of plant-specific transcription factors. A gene encoding a new member of this group was isolated from ripening oil palm fruit and designated as EgCBF3. The oil palm fruit demonstrates the characteristics of a climacteric fruit like tomato, in which ethylene has a major impact on the ripening process. A transgenic approach was used for functional characterization of the EgCBF3, using tomato as the model plant. The effects of ectopic expression of EgCBF3 were analyzed based on expression profiling of the ethylene biosynthesis-related genes, anti-freeze proteins (AFPs), abiotic stress tolerance and plant growth and development. The EgCBF3 tomatoes demonstrated altered phenotypes compared to the wild type tomatoes. Delayed leaf senescence and flowering, increased chlorophyll content and abnormal flowering were the consequences of overexpression of EgCBF3 in the transgenic tomatoes. The EgCBF3 tomatoes demonstrated enhanced abiotic stress tolerance under in vitro conditions. Further, transcript levels of ethylene biosynthesis-related genes, including three SlACSs and two SlACOs, were altered in the transgenic plants' leaves and roots compared to that in the wild type tomato plant. Among the eight AFPs studied in the wounded leaves of the EgCBF3 tomato plants, transcript levels of SlOSM-L, SlNP24, SlPR5L and SlTSRF1 decreased, while expression of the other four, SlCHI3, SlPR1, SlPR-P2 and SlLAP2, were up-regulated. These findings indicate the possible functions of EgCBF3 in plant growth and development as a regulator of ethylene biosynthesis-related and AFP genes, and as a stimulator of abiotic stress tolerance.

    The research goal is to determine the pathogenic relationship between the dynamic changes of content of individual fractions of estrogen, progesterone, follicle-stimulating hormone, luteinizing hormone and somatotropic hormone in blood of patients with breast cancer from the stage of neoplasia spread. Methods: The authors have performed comparative evaluation of functional state of hypothalamic — pituitary — gonadal system in 128 patients with infiltrating ductal breast carcinoma (clinically nodular pathology form using enzyme-linked immunosorbent analysis. Results: Examination of hormone profile of peripheral blood of patients with nodular breast cancer has revealed presence of centrogenous hormone influence on peripheral glands supplied by hormones of hypothalamic — pituitary system such as follicle-stimulating hormone and luteinizing hormone, these patients being of reproductive, climacteric and post-menopausal ages. At the same time, progress of initial stages of neoplastic proliferation in patients with breast cancer has been naturally accompanied by increase of estradiol level in blood, decrease of progesterone and estriol levels in blood. These levels have been parallel to the stage of neoplastic process. Hormone disbalance has been also characterized by increase of somatotropic hormone level in blood of patients with breast cancer. Hormone level increasing has been progressed by metastasizing neoplastic cells. Conclusion: The leading role in the pathogenesis of breast cancer in patients of different age groups should be assigned to the development of hormone disbalance. It should be noted that the principle of «feedback» between the central hormone influences and blood levels of hormones of peripheral glands has not been determined.

    Full Text Available The effect of post-harvest application of 1-methylcyclopropene (1-MCP on ethylene emission in early-winter apple (cv. ‘Calville’, winter (‘Gloster’, ‘Golden Delicious’ and ‘Jonagold’, and late-winter cultivars (‘Granny Smith’, ‘Idared’ and ‘Reinette Simirenko’ w as investigated. The fruits were picked at a commercial harvest time and half of them were treated with 1-MCP (‘SmartFresh™’ 0.068 gm-3 for 24 h at 5 °C. Then both groups of apples were placed in a common storage at the temperature of 2 °C. The intensity of fruit ethylene emission (rate of ethylene production was measured and 1 -MCP inhibition index was calculated. During storage, activity of ethylene emission by control apples of ‘Calville’ and ‘Golden Delicious’ showed typical climacteric pattern, while the intensity of ethylene emission of apples of other cultivars only increased gradually. The change of ethylene activity of early-winter apple cv. ‘Calville’ and winter cv. ‘Jonagold’, both treated with 1-MCP after harvest, had exponential character, especially actively increasing after 3 months of storage. At the same time ethylene emission of 1 -MCP treated fruits of other cultivars changed steadily to a low level and was effectively suppressed during the whole 6-month period of storage in normal atmosphere. The value of inhibition index of fruits treated by 1-MCP confirmed the consistent restoration of the ability to ethylene synthesis and thus to post-harvest ripening of some apples cultivars.

    Fruit ripening is a physiological and biochemical process genetically programmed to regulate fruit quality parameters like firmness, flavor, odor and color, as well as production of ethylene in climacteric fruit. In this study, a transcriptomic analysis of mango (Mangifera indica L.) mesocarp cv. "Kent" was done to identify key genes associated with fruit ripening. Using the Illumina sequencing platform, 67,682,269 clean reads were obtained and a transcriptome of 4.8 Gb. A total of 33,142 coding sequences were predicted and after functional annotation, 25,154 protein sequences were assigned with a product according to Swiss-Prot database and 32,560 according to non-redundant database. Differential expression analysis identified 2,306 genes with significant differences in expression between mature-green and ripe mango [1,178 up-regulated and 1,128 down-regulated (FDR ≤ 0.05)]. The expression of 10 genes evaluated by both qRT-PCR and RNA-seq data was highly correlated (R = 0.97), validating the differential expression data from RNA-seq alone. Gene Ontology enrichment analysis, showed significantly represented terms associated to fruit ripening like "cell wall," "carbohydrate catabolic process" and "starch and sucrose metabolic process" among others. Mango genes were assigned to 327 metabolic pathways according to Kyoto Encyclopedia of Genes and Genomes database, among them those involved in fruit ripening such as plant hormone signal transduction, starch and sucrose metabolism, galactose metabolism, terpenoid backbone, and carotenoid biosynthesis. This study provides a mango transcriptome that will be very helpful to identify genes for expression studies in early and late flowering mangos during fruit ripening. PMID:25741352

    Watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is an important vegetable crop world-wide. Watermelon fruit quality is a complex trait determined by various factors such as sugar content, flesh color and flesh texture. Fruit quality and developmental process of cultivated and wild watermelon are highly different. To systematically understand the molecular basis of these differences, we compared transcriptome profiles of fruit tissues of cultivated watermelon 97103 and wild watermelon PI296341-FR. We identified 2,452, 826 and 322 differentially expressed genes in cultivated flesh, cultivated mesocarp and wild flesh, respectively, during fruit development. Gene ontology enrichment analysis of these genes indicated that biological processes and metabolic pathways related to fruit quality such as sweetness and flavor were significantly changed only in the flesh of 97103 during fruit development, while those related to abiotic stress response were changed mainly in the flesh of PI296341-FR. Our comparative transcriptome profiling analysis identified critical genes potentially involved in controlling fruit quality traits including α-galactosidase, invertase, UDP-galactose/glucose pyrophosphorylase and sugar transporter genes involved in the determination of fruit sugar content, phytoene synthase, β-carotene hydroxylase, 9-cis-epoxycarotenoid dioxygenase and carotenoid cleavage dioxygenase genes involved in carotenoid metabolism, and 4-coumarate:coenzyme A ligase, cellulose synthase, pectinesterase, pectinesterase inhibitor, polygalacturonase inhibitor and α-mannosidase genes involved in the regulation of flesh texture. In addition, we found that genes in the ethylene biosynthesis and signaling pathway including ACC oxidase, ethylene receptor and ethylene responsive factor showed highly ripening-associated expression patterns, indicating a possible role of ethylene in fruit development and ripening of watermelon, a non-climacteric fruit. Our analysis provides

    Changes in ethylene production rate, respiration rate, and aroma volatile composition was determined from the immature to mature stage in "Hujingmilu"peach (Prunus presica) fruit. Flesh firmness, fruit size,ground color of skin, and total soluble solids (TSS),titratable acidity (TA) in juice were analyzed, and ACC,ACC synthase and ACC oxidase activities were measured. With the increase of fruit maturity, fruit size, L* value, and TSS and major reducing sugar contents increased, whereas fruit firmness, skin hue angle (h°), and juice TA and organic acid contents decreased. In immature fruits, a C6-aldehydes (trans2-hexenal) and C6-alcohols (cis-3-hexenol) were the major components, corresponding to the low ethylene production and high respiration rates. With increasing of fruit maturity, the C6-C12 lactonic compounds, particularly γ- and δ-lactones became the dominant volatile constituents, which increased significantly at the climacteric stage. These facts suggest that ethylene production may be involved in the regulation of lactones production in maturing peach fruit. The activity of ACC synthase in the mesocarp declined during the climacteric rise of ethylene. ACC level and ACC oxidase activity in mesocarp were consistent with the onset of ethylene production in fruit.Major aroma volatiles are thought to form in conjunction with the initiation of climacteric rises in respiration and ethylene production. Detection of changes in aroma volatile compound synthesis rate in peach may be useful as index of maturity reflecting the current physiological stage of peach fruit development.%以"湖景蜜露"水蜜桃(Prunus persica L.)为试材,检测了果实从未成熟到成熟发育过程中乙烯生成、呼吸速率及挥发性香气性物质的变化;同时对果实大小、果皮色泽、果肉硬度、可溶性固形物、可滴定酸进行了测定;对与果实乙烯产生密切相关的1-氨基环丙烷-1-羧酸(ACC)含量、ACC合成酶活性、ACC氧化酶活

    Full Text Available Abstract Background During ripening, climacteric fruits increase their ethylene level and subsequently undergo various physiological changes, such as softening, pigmentation and development of aroma and flavor. These changes occur simultaneously and are caused by the highly synchronized expression of numerous genes at the onset of ripening. In tomatoes, the MADS-box transcription factor RIN has been regarded as a key regulator responsible for the onset of ripening by acting upstream of both ethylene- and non-ethylene-mediated controls. However, except for LeACS2, direct targets of RIN have not been clarified, and little is known about the transcriptional cascade for ripening. Results Using immunoprecipitated (IPed DNA fragments recovered by chromatin immunoprecipitation (ChIP with anti-RIN antibody from ripening tomato fruit, we analyzed potential binding sites for RIN (CArG-box sites in the promoters of representative ripening-induced genes by quantitative PCR. Results revealed nearly a 5- to 20-fold enrichment of CArG boxes in the promoters of LeACS2, LeACS4, PG, TBG4, LeEXP1, and LeMAN4 and of RIN itself, indicating direct interaction of RIN with their promoters in vivo. Moreover, sequence analysis and genome mapping of 51 cloned IPed DNAs revealed potential RIN binding sites. Quantitative PCR revealed that four of the potential binding sites were enriched 4- to 17-fold in the IPed DNA pools compared with the controls, indicating direct interaction of RIN with these sites in vivo. Near one of the four CArG boxes we found a gene encoding a protein similar to thioredoxin y1. An increase in the transcript level of this gene was observed with ripening in normal fruit but not in the rin mutant, suggesting that RIN possibly induces its expression. Conclusions The presented results suggest that RIN controls fruit softening and ethylene production by the direct transcriptional regulation of cell-wall-modifying genes and ethylene biosynthesis genes

    Full text. Ethylene is an important harmone in plant biology because it activates gene expression with consequences at all phases of plant growth and development spanning seed germination to fruit ripening and senesense of plant organs. In climacteric fruits, the sharp increase in ethylene production at the onset of ripening is throught to trigger the changes in colour, aroma, texture and flavour. The final step in ethylene biosynthesis is catalyzed by ACC oxidase. Biothechnological methods have been used to inhibit ethylene biosynthesis and ripening in tomato by down-regulating ACC synthase and ACC oxidase gene expression using the antisense RNA strategy. A similar goal has been achieved by overexpressing a bacterial ACC deaminase or a viral-S-adenosylmethionine hydrolase gene, which reduces the availability of the ethylene precursors., ACC and S-adenosylmethionine, respectively. C0{sub 2} at concentrations commonly found in the intracellular space of plant tissues is required to active ACC oxidase to produce ethylene and can elevate enzyme activity 20-fold in a concentration dependent manner. Consequently, the intracellular ethylene level is modulated from low inactive levels when C0{sub 2} is not limiting and this may alter gene expression. ACC oxidase undergoes catalytic inactivation as the reaction to make ethylene procedes and this too may involve CO{sub 2}. It has been suggested that CO{sub 2}acts as a modulator of ACC oxidase activity and therby helps regulate ethylene levels in the cell and thus may explain many ethylene related phenomena in plant biology. CO{sub 2} is know to affect O{sub 2} binding in hemoglobin and ribulose bisphosphate carboxylase-oxygenase (Rubisco). Catalytic inactivation is a common phenomena in enzyme turnover, ACC oxidase is a Fe{sup +2}/ascorbate requiring enzyme and this makes it a prime candidate for metal ion oxidation-based inactivation.

The preservation effects of different concentrations of salicylic acid in the coating treatment on tomatoes were studied. The results showed that salicylic acid could inhabit the peak time of respiratory rate of the climacteric in ripening tomato fruit and reduce the respiration rate. It could keep the hardness, soluble solids, titratable acid and vitamin C of tomato. Meanwhile, it could decrease the water evaporation and decrease weightlessness rate of fruit. The better concentration of salicylic acid that coated tomatoes fruit in preservation was 0.5g/L.

    Full Text Available Ethylene regulates a myriad physiological and biochemical processes in ripening fruits and is accepted as the ripening hormone for the climacteric fruits. However, its effects on metabolome and resulting fruit quality are not yet fully understood, particularly when some of the ripening-associated biochemical changes are independent of ethylene action. We have generated a homozygous transgenic tomato genotype (2AS-AS that exhibits reduced ethylene production as a result of impaired expression of 1-aminocyclopropane-1-carboxylate synthase 2 gene by its antisense RNA and had a longer shelf life. Double transgenic hybrid (2AS-AS x 579HO developed through a genetic cross between 2AS-AS and 579HO (Mehta et al., 2002 lines resulted in significantly higher ethylene production than either the WT or 2AS-AS fruit. To determine the effects of reduced ethylene and introgression of higher polyamines’ trait, the metabolic profiles of ripening fruits from WT (556AZ, 2AS-AS, and 2AS-AS x 579HO lines were determined using 1H-NMR spectroscopy. The levels of Glu, Asp, AMP, Adenosine, Nucl1 and Nucl2 increased during ripening of the WT fruit. The increases in Glu, Asp, and AMP levels were attenuated in 2AS-AS fruit but recovered in the double hybrid with higher ethylene and polyamine levels. The ripening-associated decreases in Ala, Tyr, Val, Ile, Phe, malate and myo-inositol levels in the 2AS-AS line were not reversed in the double hybrid line suggesting a developmental/ripening regulated accumulation of these metabolites independent of ethylene. Significant increases in the levels of fumarate, formate, choline, Nucl1 and Nucl2 at most stages of ripening fruit were found in the double transgenic line due to introgression with higher-polyamines trait. Taken together these results show that the ripening-associated metabolic changes are both ethylene dependent and independent, and that the fruit metabolome is under the control of multiple regulators, including

    Full text. Ethylene is an important harmone in plant biology because it activates gene expression with consequences at all phases of plant growth and development spanning seed germination to fruit ripening and senesense of plant organs. In climacteric fruits, the sharp increase in ethylene production at the onset of ripening is throught to trigger the changes in colour, aroma, texture and flavour. The final step in ethylene biosynthesis is catalyzed by ACC oxidase. Biothechnological methods have been used to inhibit ethylene biosynthesis and ripening in tomato by down-regulating ACC synthase and ACC oxidase gene expression using the antisense RNA strategy. A similar goal has been achieved by overexpressing a bacterial ACC deaminase or a viral-S-adenosylmethionine hydrolase gene, which reduces the availability of the ethylene precursors., ACC and S-adenosylmethionine, respectively. C02 at concentrations commonly found in the intracellular space of plant tissues is required to active ACC oxidase to produce ethylene and can elevate enzyme activity 20-fold in a concentration dependent manner. Consequently, the intracellular ethylene level is modulated from low inactive levels when C02 is not limiting and this may alter gene expression. ACC oxidase undergoes catalytic inactivation as the reaction to make ethylene procedes and this too may involve CO2. It has been suggested that CO2acts as a modulator of ACC oxidase activity and therby helps regulate ethylene levels in the cell and thus may explain many ethylene related phenomena in plant biology. CO2 is know to affect O2 binding in hemoglobin and ribulose bisphosphate carboxylase-oxygenase (Rubisco). Catalytic inactivation is a common phenomena in enzyme turnover, ACC oxidase is a Fe+2/ascorbate requiring enzyme and this makes it a prime candidate for metal ion oxidation-based inactivation.

  13. Food irradiation and its role in shelf life extension of horticulture produce: a comprehensive evaluation of studies carried out in India and abroad

    International Nuclear Information System (INIS)

    Food irradiation is the process of treating foods to a controlled source of ionizing radiation, to reduce post-harvest losses and ensure its safety. With respect to horticulture produce, the role of food irradiation has been well established to fulfill the phytosanitary requirement of the importing countries and also to ensure food safety in certain commodities. Still for establishing its relevance in extending the shelf-life of horticulture produce, substantial scientific inputs are required. Our objective was therefore to summarize in brief the research findings where role of radiation processing in shelf-life extension of horticulture produce has been addressed. Low dose (0.1 kGy) of γ-radiation resulted in sprout inhibition in potatoes and onions, thus prolonging their storage life upto 4 months at 11-12℃. Radiation processing also delayed ripening process in the climacteric fruits by a week upto one month depending on the cultivars and stored condition. Shelf-life of button mushroom (Agaricus bisporus) was extended up to 10-15 days by γ-radiation treatment of 2-3 kGy and storage at 10±2℃ . A 5 kGy radiation dose and 10℃ storage temperature increased the shelf life of peeled ginger samples upto 70 days. Irradiation of guava fruits with 0.1 kGy γ-radiation increased its post harvest life by 8 days. Shelf-life of Litchi was increased upto 28 days by radiation treatment at 0.5 kGy and subsequent low temperature storage. Shelf-life of leafy vegetables increased upto 20 days by a combination process including γ-radiation (Khade, et.al., unpublished data). Electron beam irradiation (2 kGy) extended shelf-life of fresh strawberry fruits upto 4 day. Apples irradiated at 0.2-0.4 kGy showed improved quality upto 3 months of storage. Shelled sweet corn kernels treated with combination process including γ-radiation (5 kGy) treatment showed prolonged shelf-life of 30 days at 4℃ (Kumar S. et.al., unpublished data).

    The risk of cardiovascular disease and atherosclerosis progression is significantly increased after menopause, probably due to the decrease of estrogen levels. The use of hormone replacement therapy (HRT) for prevention of cardiovascular disease in older postmenopausal failed to meet expectations. Phytoestrogens may induce some improvements in climacteric symptoms, but their effect on the progression of atherosclerosis remains unclear. The reduction of cholesterol accumulation at the cellular level should lead to inhibition of the atherosclerotic process in the arterial wall. The inhibition of intracellular lipid deposition with isoflavonoids was suggested as the effective way for the prevention of plaque formation in the arterial wall. The aim of this double-blind, placebo-controlled clinical study was to investigate the effect of an isoflavonoid-rich herbal preparation on atherosclerosis progression in postmenopausal women free of overt cardiovascular disease. One hundred fifty-seven healthy postmenopausal women (age 65 ± 6) were randomized to a 500 mg isoflavonoid-rich herbal preparation containing tannins from grape seeds, green tea leaves, hop cone powder, and garlic powder, or placebo. Conventional cardiovascular risk factors and intima-media thickness of common carotid arteries (cIMT) were evaluated at the baseline and after 12 months of treatment. After 12-months follow-up, total cholesterol decreased by 6.3% in isoflavonoid-rich herbal preparation recipients (p = 0.011) and by 5.2% in placebo recipients (p = 0.020); low density lipoprotein (LDL) cholesterol decreased by 7.6% in isoflavonoid-rich herbal preparation recipients (p = 0.040) and by 5.2% in placebo recipients (non-significant, NS); high density lipoprotein (HDL) cholesterol decreased by 3.4% in isoflavonoid-rich herbal preparation recipients (NS) and by 4.5% in placebo recipients (p = 0.038); triglycerides decreased by 6.0% in isoflavonoid-rich herbal preparation recipients (NS) and by 7.1% in

    Full Text Available Abstract Background Assumptions underlying placebo controlled trials include that the placebo effect impacts on all study arms equally, and that treatment effects are additional to the placebo effect. However, these assumptions have recently been challenged, and different mechanisms may potentially be operating in the placebo and treatment arms. The objective of the current study was to explore the nature of placebo versus pharmacological effects by comparing predictors of the placebo response with predictors of the treatment response in a randomised, placebo-controlled trial of a phytotherapeutic combination for the treatment of menopausal symptoms. A substantial placebo response was observed but no significant difference in efficacy between the two arms. Methods A post hoc analysis was conducted on data from 93 participants who completed this previously published study. Variables at baseline were investigated as potential predictors of the response on any of the endpoints of flushing, overall menopausal symptoms and depression. Focused tests were conducted using hierarchical linear regression analyses. Based on these findings, analyses were conducted for both groups separately. These findings are discussed in relation to existing literature on placebo effects. Results Distinct differences in predictors were observed between the placebo and active groups. A significant difference was found for study entry anxiety, and Greene Climacteric Scale (GCS scores, on all three endpoints. Attitude to menopause was found to differ significantly between the two groups for GCS scores. Examination of the individual arms found anxiety at study entry to predict placebo response on all three outcome measures individually. In contrast, low anxiety was significantly associated with improvement in the active treatment group. None of the variables found to predict the placebo response was relevant to the treatment arm. Conclusion This study was a post hoc analysis

    genotype with a similar phenotype, i.e. seeded, bright red flesh, dark green rind, etc., determined that ethylene levels were highest during the green fruit stage followed by a decrease during the white and pink fruit stages. Additionally, quantitative Real-Time PCR was used to validate modulation of 127 ESTs that were differentially expressed in developing and ripening fruits based on array analysis. Conclusion This study identified numerous ESTs with putative involvement in the watermelon fruit developmental and ripening process, in particular the involvement of the vascular system and ethylene. The production of ethylene during fruit development in watermelon gives further support to the role of ethylene in fruit development in non-climacteric fruits.

    Xyloglucan endotransglycosylase (XET) is thought to be involved in fruit softening through disassembly of xyloglucan, which is the predominant hemicellulose of cell wall. To study the relationship between fruit softening and XET during banana (Musa acuminata Colla cv. Grand Nain) fruit ripening, a full length cDNA (1 095 bp) encoding an XET, MA-XET1, was isolated from ripening banana fruit using RT-PCR and RACE-PCR (rapid amplification of cDNA ends) methods. Sequence analysis showed that the cDNA contains 5' untranslated region of 66 bp, 3' untranslated region of 189 bp and ORF of 840 bp, encoding a predicted polypeptide of 280 amino acids, including DEIDFEFL motif, which is a presumptive catalytic domain conserved in XETs. DNA gel blot analysis demonstrated that MA-XET1 is encoded by a multi-copyfamily in the banana genome. RNA gel blot analysis revealed that the level of MA-XET1 transcript in the pulp was undetectable, increased and decreased slightly at the preclimacteric, climacteric and postclimactericstages, respectively. In the peel, accumulation of MA-XET1 transcript was low, increased dramatically andthen decreased rapidly, at preclimacteric, climacteric and postclimacteric stages, respectively. Treatment of fruit with propylene, an analog of ethylene, decreased the firmness and enhanced the accumulation of MA-XET1 transcript in the peel and pulp. These results suggest that MA-XET1 is involved in softening of the peel and pulp during banana fruit ripening and its expression is regulated by ethylene at transcriptional level.%木葡聚糖内糖基转移酶(Xyloglucan endotransglycosylase,XET)通过分解细胞壁半纤维素多糖的主要成分--木葡聚糖而参与果实软化.为了阐明香蕉(Musa acuminata.Colla cv.GrandNain)果实成熟过程中的软化与细胞壁代谢酶XET基因表达模式的关系,采用RT-PCR和RACE-PCR方法,首次从成熟香蕉果实果肉中分离了编码XT基因的全长cDNA(MA-XET1,全长1 095 bp

    Pineapple belongs to the genusAnanas in the familyBromeliaceae, which is one of important tropical fruits in China and has the unique flavor people love. Pineapple industry has become an important industry in the development of agricultural economy in the tropical and subtropical regions, and about 60% of them are consumed in the form of fresh fruit in the producing area. However, ripe pineapples are not able to be kept for a long time, and easily suffer softening and blackheart. 1-methylcyclopropene (1-MCP) is a commonly used inhibitor of ethylene receptor, which is specifically and irreversibly bound to ethylene receptors to delay fruit ripening and senescence. Previous research results showed that 1-MCP postponed the softening of climacteric fruits, kept the quality of fruits in storage and extended the shelf life of fruits. Some research reported that 1-MCP inhibited the softening of non-climacteric fruits. Pineapple is a typical non-climacteric fruit and the effect of 1-MCP on pineapple fruit is rarely reported. The purpose of this study was to investigate the effects of 1-MCP treatment on postharvest physiology and quality of pineapple, and provide a theoretical basis for the storage of fresh pineapple. The tested variety was ‘Bali’ pineapple. Harvested mature fruits were transported to the laboratory immediately, and then the fruits with the same size and being healthy were selected, washed and dried in natural air ventilation for test. Tested pineapple fruits were put into airtight boxes with different 1-MCP concentrations for 12 h at room temperature (25℃), then the fruits were placed in an incubator with about 85% humidity. Fruits treated by air were used as the control. Physiological indices related to fruit quality were evaluated, such as fruit firmness, malondialdehyde (MDA), total soluble solids (TSS), titratable acid (TA), vitamin C (VC) content and ethylene production. Activities of lipoxygenase (LOX), catalase (CAT) and peroxidase (POD) were

    Full Text Available The fatty acid composition of medlar (Mespilus germanica L. varied significantly among the ripening stages sampled at 157, 172 and 187 DAFs (days after full bloom. Twenty-one different fatty acids were detected in preclimacteric fruit and 17 when the climacteric began. Principal fatty acids, determined in medlar fruit harvested from October (157 and 172 DAFs to November (187 DAF were mainly palmitic acid (16:0, linoleic acid (18:2n-6, and a-linolenic acid (18:3n-3. While the content of saturated fatty acids [palmitic acid (16:0 and stearic acid (18:0] increased, the content of the essential polyunsaturated fatty acids [linoleic acid (18:2n-6 and linolenic acid (18:3n-3] decreased through ripening, in parallel with pulp darkening. The percentage of linoleic acid and a-linolenic acid in ripe, hard fruits was 60.0 and 13.5 % of dry wt at 157 DAF which decreased throughout ripening, remaining at 28.7 and 5.6 % of dry wt, respectively, in the fully softened and darkened pulp. A marked decreases in the double bond index, percentage of unsaturation and the ratio of unsaturation/saturation were also seen throughout the medlar ripening. The contribution of unsaturated fatty acid to the total fatty acid content decreased markedly as the medlar fruit became progressively softer and darkened.La composición en ácidos grasos del níspero (Mespilus germanica L. varió significativamente entre los estados de maduración muestreados a los 157, 172 y 187 DAFs (días después de la floración.

    Background: the life of women, being extended to 30 years after menopause, undergoes an environmental impact that overlaps the clinical expression of the cessation of reproductive function. This increases the need to provide, at this stage, a comprehensive care. Objective: To identify some biological and social factors related to women's health during climateric. Methods: Descriptive and cross sectional study conducted in 307 women from 40 to 59 years old in the Area III Polyclinic of Cienfuegos, from January to December 2006. Through household interviews, a form that allowed collecting general, clinical and medical support information was filled. Results: 56.3% of women experienced mild climacteric syndrome, circulatory (77.2% and psychological (60% symptoms being the most referred ones. The average age of menopause onset was between 47 and 51 years old. It appeared earlier in smokers. The age of menarche, the number of pregnancies and births and menstrual patterns were not related to the age of menopause onset. 44% of women were hypertensive, 41.4% were pre-obese and 100% were sedentary. 81.8% of them did not seek for medical support. Hormonal therapy was prescribed for 32.1% of patients. Conclusions: Despite the risk factors and the chronic diseases that were detected, women interviewed did not seek for medical support, even when they presented discomfort to some extent. This was caused by the lack of information on this stage of life and the inexistence of specialized multidisciplinary consultations in Primary Health Care.

    [Objective]This study aimed at investigating the effecf of dehydration treatment on postharvest physiology of Actinidia arguta Sieb. et Zucc. [Method] The fruits were stored at room temperature(20± 0.5)℃ after dehydration treatment, and the dehydration rate was 2%, 4% and 6%, respectively. The effect of dehydration treatment on postharvest physiology of Actinidia arguta was discussed. [Result]The results demonstrated that appropriate dehydration could both restrain the respiration intensity of Actinidia arguta and postpone the peak time, and also could inhibite the release of ethylene, postpone the peak of ethylene and the arrival of climacteric. The peak valume was reduced by this treatment. Proper dehydration could reduce pectinase activity, and inhibit decomposition of pectin during the whole storage. This treatment maintained the fruit firmness and flavor, and therefore, the fruit maturation and aging process were delayed. Among the three dehydration rates, 4% of fruit dehydration had a significant performance. When the fruits treated with dehydration of 4% stored 10 days, the decay rate was 37.23%, which was significantly lower than that of the other treatment groups(P<0.05). [Conclusion]Thus the experiment indicated that dehydration rate of 4% had fairly good effects on the storage and fresh-keeping of Actinidia arguta.%[目的]为了探讨失永处理对采后软枣猕猴桃生理生化变化的影响,[方法]以软枣猕猴桃为试验材料,研究了失水率分别为0、2%、4%、6%的软枣猕猴桃,在温度(20±0.5)℃条件下贮藏过程中生理生化变化.[结果]结果表明,适当失水处理可有效抑制软枣猕猴桃果实的呼吸作用,降低呼吸强度和推迟呼吸高峰出现;同时也抑制乙烯的释放量,推迟乙烯高峰和呼吸跃变的到来,并降低其峰值;适当失水处理也明显降低了软枣猕猴桃的果胶酶活性,抑制了果胶的降解,保持了果实硬度和风味,从而延缓软枣猕猴

    40 and 65 years of age, with 11 years or more of formal education. Some women added spontaneous comments to the end of the questionnaire on sexuality handed out by research assistants and self-responded anonymously. There were those who provided comments at the end of the questionnaire and those who did not. The groups were compared with respect to sociodemographic and reproductive characteristics using Pearson's chi-square test. Comments were transcribed in their entirety to a computerized file for thematic content analysis, and units of meaning were identified and classified. RESULTS: Approximately one-third of the women (114/378 provided comments. Significantly more women with lower income levels provided comments as compared to those with higher income levels. The principal identified categories of analysis were: a uncertainty and/or confusion, mainly with regard to anguish, stress and doubts about menopause; b symptoms that lead to negative feelings, such as hot flushes, vaginal dryness and mood changes; and c hormone replacement therapy, fears and perception of a lack of conviction in the physicians who prescribe it. CONCLUSION: The comments indicate that more attention must be given to the problems perceived in climacteric women with a special emphasis on those of the lower incomes levels.

    The climacteric is not an illness, but the menopause is an event that troubles a woman's present life and puts her future life at risk. One would like to think that, for the woman of the new millennium, the menopause has simply become what it is: a feminine milestone that marks the transition and path to another period of life. She appears younger than her mother was at her age, she has given birth when she decided to, she has had the number of children she wanted, and her social and professional roles are well defined. Nevertheless, none of this makes much difference--the 'change of life' is still something difficult to live through, a bend to negotiate, each woman going at her own pace, using her own means, with the cards that life has already dealt her. Where do we gynecologists come in, what part have we to play in our patients' lives? Sometimes, we need to be less discreet and ask some of those questions women may have trouble voicing aloud. Let us try to help them to talk about their mood changes, the changes in their body, and their anxiety about osteoporosis and aging. Shame or fear of ridicule are still often among the ideas on the menopause and, by preventing honest answers from being given, often modify the scientific statistics on menopausal women--especially as women are often at a loss to know which of the different opinions to believe. The media air their news, the medical community offers its dissent, while friends recount frightening stories. Between the danger of offending Mother Nature and the risk of missing out on the progress of science, what is the right modus operandi that helps to add quality to the quantity of life still there to be enjoyed after the menopause? The doctor-patient relationship is of the utmost importance here, since an atmosphere of confidence and trust is the basis of mutual comprehension. By understanding the patient's needs, her desires, and her ways of coping with the situation, the physician will enable her to accept

    Full Text Available Abstract. Fruit consumption is increasing around the world, just as its population. The World Health Organization recommends a minimum consumption of fruit 120 kg/person - year. Fruits such as soursop provide nutrients, phytochemicals and antioxidants which are vital to human health, as well as bioactive substances such as vitamin C, flavonoids, anthocyanins and carotenoids, among others. In this research, soursop (Annona muricata L. cv. Elita fruits were collected at physiological maturity in two production seasons for their physiological (respiration rate, ethylene production and physiological loss of weight and physico-chemical characterization (pulp, seeds and skin yield, total soluble solids (TSS, total acidity, pH and firmness. We found that ethylene production peaked at day 6 after-harvest, scoring 133.2 mL kg-1 h-1. This parameter was found to increase during postharvest, with peaks on days 4 and 6, coinciding with the climacteric peaks of biphasic respiration, the largest of which reached a value of 186.9 mg CO2 kg-1 h-1. This is probably the starter for the cascade of events that feature the ripening process, among which changes in TSS, acidity and fruit firmness were outstandingly visible.Resumen.

    . vinifera fruits suffered chilling injury when stored at 8 ºC and the damaged fruits failed to ripen upon return to 25ºC storage. Subjected to low water loss in high humidity chambers M. vinifera fruit-storage life tripled when compared to less humid storage environment (65 to 85%, also at 25 ºC. The hard M. vinifera fruit peel became more gas permeable as it loses firmness and tight scale arrangement during ripening and also during storage at stressful chilled temperatures. Intercellular gaseous volume was low in M. vinifera fruits, a fact that may increase susceptibility to impact injury caused by a tendency of the hard peel scales to split or unglue. As it ripens the fruit pulp became soft, as recorded by a penetrometer, thus reducing transport resistance, the fruit becoming susceptible to even modest compression. M. vinifera had typical climacteric ripening behavior with the CO2 peak occurring two days after the ethylene peak. The internal CO2 and O2 curves were different from those of previously described fruits because there was a great reduction in peel diffusion resistance caused by the formation of openings between the hard peel scales during ripening.

    Full Text Available There is some controversy regarding the respiratory pattern of loquat (Eriobotrya japonica [Thunb.] Lindl.. Thus in order to provide information on this aspect of loquat, fruit of 50-70 g, from cv. Golden Nugget were harvested in four stages of maturity: green (BBCH 709, color break (BBCH 801, yellow (BBCH 807, and orange (BBCH 809. The parameters evaluated in each stage were: soluble solids, titratable acidity, respiration, ethylene generation, and activity of the enzymes pectin methyl esterase (PME, peroxidase, polyphenoloxidase (PPO, polygalacturonase (PG, and cellulose, and the soluble solids:acidity ratio was calculated. The results show that ethylene concentration increased at the time of color break, which was not the case for the change in the respiratory rate. The activity of the peroxidase enzyme increased from the green stage to color break, while the enzymes PME, cellulase, and PG showed a constant reduction from the green to the orange stage, and PPO showed no change over the four stages studied. With regards to quality, from color break onwards soluble solids increased to 11.8 °Brix and titratable acidity dropped from 0.67 to 0.28 g L-1 malic acid. Based on these results, the conclusion is that towards the end of its development loquat cv. Golden Nugget evidence enzymatic and ethylene behavior similar to that of climacteric fruits.Existe controversia sobre el patrón respiratorio del níspero (Eriobotrya japonica [Thunb.] Lindl..

    different periods of storage. After storage for 120 d, walnut shell color, endotesta color, kernel flavour of total fresh walnut fruit were evaluated, respectively. Then, the appearance of fresh walnut husk, shell and kernel were taken photo.[Result]The results showed that the fresh walnut fruit with green husk is respiration climacteric fruit and fresh walnut without green husk is non-respiration climacteric fruit. The content of moisture, lipid, and oil iodine value presented a reduced trend, but the acid value, peroxide value, LOX activity, and MDA content of fresh walnut kernel showed a increased trend and SOD activity, CAT activity, reducing sugar content, protein content showed no visible change. The contrast treatment showed the worst preservation effect and green husk browning index reached 0.27 after storage for 40 d. However, the green husk browning index of vacuum-package with plastic bag storage was only 0.18 after storage for 120 d. The result also showed that the treatment of vacuum-package with plastic bag could effectively prevent browning of green husk, maintain the moisture of kernel, slow down the change rate of oil acid value, iodine value and peroxide value, keep the activities of SOD and CAT at a high level, inhibit the generation of MDA. By evaluating the sensory quality after storage for 120 d, the treatment of vacuum-package with plastic bag gained the highest score in every single project. [Conclusion] The lower the concentration of O2 in storage circumstances, the better the effect of conservation. After plucked with carpopodium in walnut commercial mature period, pre-cooled at 4.0℃ for 3 d, and vacuumed with LDPE plastic bag using vacuum pack machine, the storage life of walnut could reach 120 d at (1.0±0.5)℃ and RH 90%-95%. Its pericarp browning index of fresh walnut was low, and the color, aroma, taste and shape remained good.

METHODS: This was a cross-sectional study of 52 women undergoing follow-up at a university hospital in southeastern Brazil from February 4th, 2009 to January 5th, 2011. Twenty-four of these women were 35 years old or older and had undergone liver transplantation at least one year before study entry. The remaining 28 women had no liver disease and were matched by age and menstrual patterns to the patients with transplants. The abbreviated version of the World Health Organization (WHOQOL-BREF questionnaire was used to assess quality of life. Menopausal symptoms were assessed using the Menopause Rating Scale (MRS. Statistical analysis was carried out by Student's t-test, Mann-Whitney test and analysis of variance. Correlations between MRS and the WHOQOL-BREF were established by correlation coefficients. RESULTS: The mean age of the women included in the study was 52.2 (±10.4 years and the mean time since transplantation was 6.1 (±3.3 years. Women with liver transplants had better quality of life scores in the environment domain (p=0.01. No difference was noted between the two groups in any domain of the MRS.

    of jelly palm fruits. The fruits were harvested at three maturity stages (green, yellow-green, and yellow and stored at 0 2°C and 20 2°C. Fruits stored at 0 2°C showed better retention of firmness, green color of the skin, total titratable acidity (TTA, and total soluble solids (TSS than fruits stored at 20 2°C. Fruits harvested at the green maturity stage showed the best benefit from cold storage for postharvest preservation, despite of its poorest sensorial quality, characterized by the higher values of TTA and lower values of TSS than fruits harvested at yellow-green and yellow maturity stages. Fruits stored at 0 2°C did not show any symptom of chilling injury. Along the entire storage period, the fruits did not exhibit a climacteric respiratory pattern. Fruits harvested at different maturity stages did not show significant difference in terms of respiration rates. Thee increment of storage temperature from 0 to 30°C significantly increased the respiration rates from 50.26 to 658.35nmol CO2 kg-1 s-1. This respiratory increase followed a sigmoid model, with a rapid increase between 0 and 10°C, and a more modest increase towards the temperature of 30°C. There was a positive effect of immediate cooling after harvest on fruit retention of firmness, skin green color, and TTA, but not on TSS. Since jelly palm fruit is highly perishable, it should be harvested at the yellow-green maturity stage and then immediately stored at 0°C to preserve its postharvest quality.

    The consumption of strawberries is preferable because of its nutritional value and special flavor. The ripe strawberry has an extremely short postharvest life because it is highly susceptible to mechanical injury, microbiological decay, and physiological deterioration. On the other hand, the strawberry is non-climacteric and will not ripen after harvest, therefore it has to be picked when fully ripened for the best eating quality. Current methods used for preventing undesirable changes of fruit attributes during storage have a detrimental effect on nutritional properties. Therefore, it’s necessary to find appropriate methods to extend the shelf life and maintain the quality of the strawberry. The investigations of ultrasound and slightly acidic electrolyzed water (SAEW) used in postharvest fruits and vegetables have gained much attention in recent years. Ultrasound is one of the newest nonthermal methods to extend the shelf life of fruits during storage. Slightly acidic electrolyzed water (SAEW) is regarded as a novel and promising alternative method of disinfection in fresh products. It is hoped that ultrasound and SAEW could play a role in the preservation of the strawberry. This study was performed to investigate the effect of ultrasound and SAEW on the quality of an immature strawberry. The impact of SAEW and ultrasound, separately or in combination, on total aerobic bacteria and yeast and mold was studied. Quality attributes including firmness, total soluble solids (TSS), total titratable acidity (TA), vitamin C (VC), and anthocyanin content were also investigated. Results showed that ultrasound and SAEW alone or combined significantly removed about 0.52, 1.07, 1.29 lg CFU/g for total aerobic bacteria and 0.30, 0.93, 1.18 lg CFU/g for yeast and mold, respectively. And the treated samples also maintained relatively low microbial loads during storage. It was observed that the three treatments changed the respiratory characteristic of strawberries and a

    Objective:To investigate the influence of preventive acupuncture and preventive moxibustion at Guanyuan (CV4) point on the expression of insulin receptor in hypothalamus and abdominal fat of natural climacteric model rats. Methods: A total of 60 female SD rats were randomized into 10th, 12th, 14th, 16th month control groups, 12th, 14th, 16th month preventive moxibustion groups and 12th, 14th, 16th month preventive acupuncture groups with 6 rats in each group. In addition, other 6 female SD rats aged 3.5th month were used as young control group. In preventive acupuncture and preventive moxibustion groups, Guanyuan was punctured with the needle retained for 20 min, and given with moxibustion for one moxa-cone respectively from aged 10th month. The treatment was conducted twice every week, 8 weeks altogether. The expression of insulin receptor in hypothalamus and abdominal fat was observed by immunohistochemical method. Results: As the growing of month, the expression of insulin receptor in hypothalamus during early menopause increased and then decreased, the expression of insulin receptor in abdominal adipose tissues of meopausal rats decreased at the beginning, increased in the middle stage and decreased in the end. With preventive acupuncture and preventive moxibustion at Guanyuan point, the expression of insulin receptor in hypothalamus and abdominal fat presented an adverse trend compared to the same month control groups in most of the groups.Conclusion: Preventive acupuncture and preventive moxibustion at Guan-Yuan point had an benign regulation on the expression of insulin receptor in hypothalamus and abdominal adipose tissues, which might be one of the mechanism of preventing effectively dyslipidosis.%目的:观察逆针灸关元穴对自然更年期大鼠胰岛素受体表达的影响.方法:经阴道筛查出动情周期紊乱的10月龄SD雌性大鼠60只,随机分为自然10、12、14、16月龄组、逆灸12、14、16月龄组和逆针12、14、16

    from March 1993 to August 2001, and the risk factors for CHD were studied. During examination the pressures, at the aortic root, and coronary obstructions were visually assessed by 2 interventional cardiologists, and those stenosis over 70% were considered severe. RESULTS: Eight-one per cent of the population was white and 18.3% was black. Mean age was 59.2±11.2 years, and it was significantly higher in patients with severe coronary lesions: 61.9 ± 10.8 years versus 56.4 ± 10.8 years; smoking, diabetes mellitus and climacteric were more frequent in patients with CHD. The average mean arterial pressure and mean systolic blood pressure was the same in both groups, however, average left ventricle diastolic pressure (17.6 ± 8.7 x 15.1 ± 8.1, p=0.001, and aortic pulse pressure were significantly greater in patients with CHD (75.5 ± 22 x 70 ± 19, p=0.002, while average aortic diastolic pressure was significantly greater in patients without CHD (79.8 ± 16 x 75.3 ± 17.5, p=0.003. In the multivariated analysis, pulse pressure > 80 mmHg and systolic blood pressure > 165 were independently associated with severe CHD with odds ratio of 2.12 and 2.09, p 80 mmHg and systolic blood pressure > 165 mmHG determined risk two times greater of severe coronary disease.

    Full Text Available Background: Osteoporosis is one of the most important public health problems involving a high percentage of costs in the medical care system. Reliable diagnostic techniques for an early detection of bone deterioration and studies of factors that influence its development in menopausal women are crucial. The aim of the study was to determine the relationship between bone microarchitecture and anthropometry in climacteric women. Methods: Women were recruited at the Menopause Clinic, University Hospital of FMRP/USP, and submitted to anthropometry and to the evaluation of bone quality (Ultrasound Bone Profile Index, UBPI and quantity (Amplitudedependent Speed of Sound, AD-SoS- by phalangeal quantitative osteosonography (DBM Sonic BP. Descriptive analysis of the data was reported and a multiple linear regression was performed using the software SAS® 9.0. Results: 71 patients aged 58 ± 7 y were studied: 28% had BMI 18.5-24.9 kg/m², 35% BMI 24.9-29.9 and 37% BMI > 30. Mean AD-SoS was 2059 ± 79 m/s and mean UBPI was 0.67 ± 0.13. Considering AD-SoS the dependent variable, there was no statistically significant relationship between age (p = 0.20, BMI (p = 0.76, fat mass by bioelectrical impedance (p = 0.42 and by anthropometry (p = 0.95. The variables had very low effect on the UBPI when it was considered the dependent variable. Conclusions: The relation between bone microarchitecture and the anthropometry of the women studied shows that, the greater the bone quantity, the better the anthropometric parameters, without statistically significance. This work was a cross-sectional study on a small sample that needs to be validated in a prospective design.Introducción y objetivo: La osteoporosis es uno de los problemas más importantes de la Salud Pública e involucra un elevado porcentaje de los costos del Sistema de Salud.

    Objective To observe the effect of preventive-electroacupuncture (PEA) at "Guanyuan" (CV 4) and "San-yinjiao"(SP 6)on hypothalamus-pituitary-ovary (HPO)activities in ovariectomized (OVX) rats, and to compare the specificity of efficacy of acupoints. Methods Sixty-two female SD rats were randomly divided into normal group (n = 6), sham-operation (sham) group (n = 6), model group (n = 6), PEA-Guanyuan (CV4, PEA-CV4) group (n=11), PEA-Sanyinjiao (SP6, PEA-SP 6) group (n=11), complementary (C)-PEA-CV 4 (n=11) and C-PEA-SP 6 group (n = 11). Climacterium model was duplicated by removing the bilateral ovaries. Before OVX, electroacupuncture (EA, 2 Hz/100 Hz, ) was applied to bilateral SP 6, CV 4 for 20 min, once every other day for 15 times. For rats of the C-PEA-CV 4 and C-PEA-SP 6 groups and 12 days after the OVX, PEA was applied to CV 4 and SP 6 again, once every other day for 5 times. For rats of the sham group, a little of fat nearby the ovary was removed. Enzyme-linked immunosorbent assay was used to measure the contents of gonadotropin releasing hormone (GnRH) in the hypothalamus, follicule-stimulating hormone (FSH) and luteinizing hormone (LH) in the hypophysis, and estrogen (E2) in the uterus. Results In comparison with the normal group, uterus E2 content was decreased significantly (P0. 05). Conclusion Preventive EA of "Guanyuan" (CV 4) and "Sa-nyinjiao"(SP 6) can function in up-regulating uterus E2 level, and down-regulating pituitary FSH and LH contents and hypothalamic GnRH level in OVX rats, which may contribute to its efficacy in relieving climacteric syndrome in clinic.%目的:观察逆针“关元”“三阴交”穴对去卵巢大鼠下丘脑-垂体-卵巢(HPO)轴的调节作用,探讨腧穴主治作用的特异性.方法:选取3月龄SD大鼠,设正常对照组(6只)、假手术组(6只)、模型组(6只)、逆针关元组(11只)、逆针三阴交组(11只)、逆针关元续针组(11只)、逆针三阴交续针组(11只),共7组.4

    A decreased from (1.8±0.3)mg/dl to (1.7±0. 3) mg/dl significantly (P<0.05), fasting glucose decreased from (5. 6±0.8)mmol/L to (3.9±1.1) mmol/L significantly (P<0.01) and no significant differences in BMI,FSH, LH, E2, tPA, hs-CRP, NO, TG, HDL-C, LDL-C, apoB were found after treatment. In group B, there were no significant differences in other parameters found after treatment except Kupperman score and PAI-1.Conclusions: 1.25 mg/d tibolone short-term therapy was associated with improved fibrinolytic factors and decreased Kupperman score, blood pressure, total cholesterol and fasting blood glucose level. 0. 625 mg/d tibolone therapy resulted in decrease Kupperman score and improvement of fibrinolytic factors. These changes relieve climacteric symptoms and may have some benefits on preventing the development of cardiovascular disease. An increased testosterone and free testosterone levels in 1.25 mg dose of tibolone therapy may increase energy level, general wellbeing and sexual desire in postmenopausal women. Low dose tibolone replacement therapy is a convenient effective HRT for postmenopausal women

    chambers at 18.1±0.7°C and 90±3% RH, for 24h. After the treatment, the fruits were kept under the same conditions of temperature and RH, and were evaluated at 0, 1, 3, 6, 9, 12 and 15 days of storage. Ethylene and CaC2 increased mass loss of the fruits. Mangoes treated with CaC2 showed the respiratory climacteric peak at 3, 6, 9, 9 and 12 days of storage for the concentrations 160, 80, 40, 20 and 0g m-3, respectively. Fruits treated with ethylene showed the peak at 3, 3, 6, 6 and 12 days of storage for the concentrations 400, 200, 100, 50 and 0mL m-3, respectively. All concentrations of CaC2 and ethylene accelerated the loss of firmness, the increase of soluble solids and carotenoids, the reduction of acidity and the change in color of skin and pulp. However, these products also increased electrolyte leakage and decreased ascorbic acid content. Fruits treated with ethylene showed sharper firmness loss compared with fruits treated with CaC2. On the other hand, solute leakage was higher in fruits treated with CaC2. Soluble solids content increased with increasing concentrations of CaC2 and ethylene. The concentrations of 20g of CaC2 and 50mL of ethylene per chamber m³ were sufficient to accelerate and uniformize ripening of 'Ubá' mango.

    involved 90 postmenopausal patients aged 45-60 years old attended at the Outpatient Menopause Clinic. All patients had been experiencing hot flashes accompanied or not by other hypo-estrogenic symptoms. Patients were randomized to receive either two soy capsules containing 50 mg of soy-derived isoflavone or two identical placebo capsules, twice a day for 12 weeks in a double-blind fashion. Each patient was observed for 12 weeks, with two evaluations being made, one at baseline and the other at the end of the study. At each time point, the patients were given a diary to record the severity of the climacteric symptoms experienced, assessed with a modified Kupperman index, using a 100 mm Visual Analogue Scale (VAS. The intensity of hot flashes was also assessed separately. The patients were also submitted to a transvaginal echography for the measurement of endometrial thickness. Yates chi2, ANOVA or t de Student and Mann-Whitney were used for statistical analysis. RESULTS: no significant difference was detected in the Kupperman index (64 versus 82, p>0,05 or in the hot flashes (20 versus 20, p>0,05 between the isoflavone and placebo groups. No significant difference was either detected concerning the Kupperman index and hot flashes before and after treatment, when the two groups were analyzed separately. No difference was detected in the endometrial thickness either in the isoflavone or the placebo group (0.28 versus 0.26 mm, respectively, p>0.05. CONCLUSIONS: our results indicate that 100 mg of isoflavone are not more effective than placebo in reducing hot flashes and hypo-estrogenic symptoms in postmenopausal women and present no effect on the endometrium thickness.

    quais era retirada uma amostra para monitorização da produção de etileno. Estudou-se ainda a evolução, da textura, da acidez, e do SSC (teor dos sólidos solúveis dos frutos durante a sua conservação frigorífica. Dos resultados obtidos verificou-se que a conservação dos frutos a 7 ºC não influencia significativamente a produção de etileno, 0,3 nl/g/h, quando comparado com os frutos não sujeitos ao frio. Os frutos conservados à temperatura de 1 ºC durante 14 dias produziram menores quantidades de etileno quando comparados com os restantes grupos. Um período de conservação de 2 dias a 7 ºC induziu nos frutos um aumento na produção de etileno quando comparados com os frutos não sujeitos ao frio. Em ambas as temperaturas de conservação, verificou-se uma antecipação no pico do climatérico, quando se comparam frutos com e sem conservação frigorífica.Low temperatures interacts with ethylene biosynthesis and ripening in many species. Exposure fruits to low temperatures promotes ethylene biosynthesis in a number of apple and pears cultivars because low temperatures stimulates ACC synthase activity after fruits being warmed up.. Some pears and apples varieties required a cold treatment to achieve good colour, acceptable texture and flavour. In ‘Prunus domestica’ plums cv ‘Raínha Claudia verde’, a climacteric fruit, there is little information about ripening process but we observed after a cold storage period a decrease in ethylene production upon rewarming. The longer the storage period the stronger the depress in ethylene biosynthesis. This cultivar is usually stored at 0-2 ºC, it has small commercial period because of its short postharvest life. In cold chambers fruits became soft very quickly and improper to commercialise. The aim of this study was to compare the effect of two different storage temperatures (1 ºC and 7 ºC ±1º during 0, 2, 5, 8, and 14 days in ethylene production upon rewarming of ‘Raínha Claudia Verde
