During ripening, fleshy fruits undergo textural changes that lead to loss of tissue firmness and consequent softening. It is a common idea that this process is the consequence of cell wall dismantling carried out by different and orderly expressed enzymes. For this purpose, by using a single enzyme family approach many enzymes and related genes have been characterized in different fruits. In th...

Arabidopsis has been used as a model system to study many aspects of plant growth and development. However, fruit senescence in Arabidopsis has been less investigated and the underlying molecular and hormonal (especially ethylene) regulatory mechanisms are not well understood. It is reported here that the Arabidopsis silique has characteristics of a climacteric fruit, and that AtNAP, a NAC fami...

Muskmelon (Cucumis melo L.) varieties differ in a range of physical and chemical attributes. Aroma is one of the most important factors determining fruit quality and consumer preference. Volatile esters, a major class of compounds contributing to the aroma of muskmelon fruit, are synthesized by alcohol acyl-transferases (AATs). We demonstrate here that volatile aldehydes are most abundant in un...

BACKGROUND The aim of this study is to explore the efficacy of Guizhifulingwan (GFW) in the treatment of climacteric syndrome in women. METHODS/DESIGN This is a single-center, randomized, placebo-controlled, parallel-group design pilot trial. Fifty participants with climacteric syndrome will be randomly allocated to the GFW or placebo group in a 1:1 ratio. The participants will be administere...

A climacteric aromatic near-isogenic line (NIL) of melon (Cucumis melo L.) SC3-5-1 contained an introgression of the non-climacteric Korean cultivar "Shongwan Charmi" accession PI 161375 (SC) in the genetic background of the non-climacteric cultivar "Piel de Sapo" (PS). The aroma production was monitored during ripening at 21 °C in intact fruit using headspace sorptive bar extraction (HSSE). Ba...

The inhibitory effects of the cyclic olefin 2,5-norbornadiene (NBD) on ethylene action were tested in carnation (Dianthus caryophyllus L. cv White Sim) flowers. Treatment of flowers at anthesis with ethylene in the presence of 500 microliters per liter NBD increased the concentration of ethylene required to elicit a response (petal senescence), indicating that NBD behaves as a competitive inhib...

Forty-year-old man was admitted to emergency department with complains of chest pain and dispnea after exposure the pepper gas that sprayed to environment during a social event. Physical examination and electrocardiogram was revealed acute myocardial infarction.

61-year-old woman with a past medical history of dementia and Meniere's disease presents with acutely worsening dizziness and headache. The patient additionally complains of left greater than right upper extremity weakness and paresthesias.

The expression of alternative oxidase (Aox) and uncoupling proteins (Ucp) was investigated during ripening in mango (Mangifera indica) and compared with the expression of peroxisomal thiolase, a previously described ripening marker in mango. The multigene family for the Aox in mango was expressed differentially during ripening. Abundance of Aox message and protein both peaked at the ripe stage....

Hop extract is a long used medicinal product and, regarding hormonal activities, in 1999 a number of prenylflavanones have been identified as its major constituents with 8-prenylnaringenin (8-PN) being the main active estrogenic compound. There have been several in vivo studies performed that demonstrate the potential of hop extract and the single compound 8-PN to alleviate climacteric symptoms...
