 eMedicine - Cervical Ripening : Article by Jodie Rai, MD
Cervical ripening usually begins prior to the onset of labor contractions and is necessary for cervical dilatation and the passage of the fetus.
Cervical ripening is associated with decreased collagen fiber alignment, decreased collagen fiber strength, and diminished tensile strength of the extracellular cervical matrix.
Cervical ripening is associated with increased activity of matrix metalloproteinases 2 and 9, enzymes that degrade extracellular matrix proteins.

 GEO-PIE Project: Delayed fruit ripening
Delaying the ripening process in fruit is of interest to producers because it allows more time for shipment of fruit from the farmer's fields to the grocer's shelf, and increases the shelf life of the fruit for consumers.
Although ripening makes fruit edible and flavorful, it also begins the gradual decline of the fruit towards softening and rot, causing losses for producers and consumers.
Fruit that are genetically engineered to have delayed ripening can be left to mature on the plant longer, will have longer shelf-life in shipping, and may last longer for consumers.

  International Banana Association
The commercial practice is to ripen bananas artificially by using ethylene gas, a substance produced by fruits that accelerates the normal process of fruit maturation.
The temperature inside the ripening room is initially high and then is lowered according to when and what color stage the fruit needs to be taken out for shipment to the retail stores.
Longer ripening schedules, with a more gradual reduction in temperatures are better for the fruit, but in many situations ripeners allow the fruit to go through as short a cycle as possible before releasing the product to the retail outlets.

The principal biochemical events that occur in cheese during ripening are proteolysis (i.e., the hydrolysis of the caseins to peptides and free amino acids) and lipolysis (the liberation of fatty acids from triacylglycerides) and these processes are essential for the development of flavour in most cheeses.
Research on proteolysis in cheese during ripening is at the molecular level and is focussed on the specific peptide bonds cleaved by proteinases during ripening and the identification of the many hundred peptides found in cheese.
Ripening also involves the softening of cheese texture, as a consequence of the hydrolysis of the casein matrix, changes in the water-binding ability of the curd and changes in pH (which may cause other changes such as the migration and precipitation of calcium phosphate).

Ripening of tomatoes, genus Lycopersicon esculentum, is most frequently marked by an increase in redness within 40 to 60 days from flowering to full ripeness.
During this ripening process, the increased redness in the latter days of tomato maturation is due to the loss of chlorophyll and accumulation of carotenoids, particularly lycopene.
The initial most obvious change in bananas during ripening is the peel change from a green to a yellow and then to a brown color in over ripe or cold shocked bananas.

 Ripening Tomatoes With Ethylene
Ripening is the final stage of the maturation process, when the fruit changes color, softens and develops the flavor, texture and aroma that constitute optimum eating quality.
Ripening is irreversibly initiated when the internal ripening concentration of naturally-produced ethylene reaches 0.1 to 1.0 ppm; prior to this time the natural ripening process can be initiated by exposing fruits to external ethylene sources.
Decreasing the time for ripening initiation by only one day would represent substantial reduction of energy requirement, as ripening room construction and operation are high energy consumers.

 Fruit Ripening
Grape berry development and ripening is a continuous process and there is no single stage of development or point in time that the fruit can be universally considered “ripe”.
But ripening processes continue while fruit is on the vine so as flavors may be developing or changing with extended hang-time, sugars may continue to increase and acidity decrease.
The onset of grape ripening (veraison) begins during the final stage of berry growth when berries begin to soften and size increases due to cell enlargement.

 BioMed Central | Full text | IMOP: randomised placebo controlled trial of outpatient cervical ripening with isosorbide ...
Outpatient cervical ripening with prostaglandins is associated with significantly shorter admission to delivery times [2,3] and/or reduced health care costs [4].
However, there are concerns about the use of prostaglandins, the agents commonly used in hospital settings for this indication, and their use for outpatient cervical ripening has been declared unsafe by many authorities because of the potential for uterine contractions to cause fetal hypoxia which would remain undiagnosed in the outpatient environment [6,7].
A Medline search using the headings "outpatient" and "cervical ripening" and restricted to studies in the English language on human subjects generated 22 publications, of which 17 are relevant to this application [2-4,6,7,13-26].

 DOMENICO BRANCATO snc - Post-harvest solutions and technologies - RIPENING OF FRESH CROPS
The post-picking ripening of fruits is a condition of necessity which finds its employment all over the world and can be applied to the product picked in advance or in a normal picking period.
There are several techniques (described below) which, from a practical point of view, allow to reach in a short time a uniform ripening of fruits in order to allow the operators a greater timeliness of offer and therefore obtain economic advantages, a very important characteristic from a commercial point of view.
The consumption ripening - which not always coincides exactly with the physiologic ripening - is obtained in the course of time, i.e.: during the preservation and/or commercial distribution.

 Ostwald ripening
The ones in the middle or the ones you are packing in on top, trying to get them to fit?) Large crystals, with their greater volume to surface area ratio, represent a lower energy state.
Ostwald ripening is not a transition of the protein from one phase (precipitate) to another (crystal).
However, the depletion zones around the growing crystals which are seen here are also seen in Ostwald ripening and until I get some pictures of true Ostwald ripening, this is the closest example I have.

 How Steroids Control Grape Ripening
In spite of their importance, the biochemical mechanisms that control ripening in grapes are something of a mystery.
In climacteric fruit, those that continue to ripen after harvest, such as tomatoes, apples and bananas, ripening is controlled by ethylene.
Climacteric fruits are characterized by a strong increase in ethylene, together with a peak in respiration during ripening.

 Cervical Ripening
Associated with cervical ripening is an increase in the enzyme cyclooxygenase-2 (COX-2), which leads to a local increase of prostaglandin E2 (PGE2) in the cervix.
Cervical ripening is associated with increased activity of metalloproteinases, enzymes that degrade extracellular matrix proteins.
Bishop scores are somewhat subjective, but a score of 5 or less suggests further ripening is needed while a score of 9 or greater suggests that ripening is completed.

Moreover, the double bond index of fatty acids in the polar lipid fraction fell during ripening, reflecting a progressive increase in the saturation of membrane lipids.
This increase in saturation was partly due to a 65% decline in the concentration of linolenic acid.
Collectively, these results provide evidence that ripening of this climacteric fruit is accompanied by a substantial increase in free-radical-mediated peroxidation of membrane lipids, probably as a direct consequence of a progressive decline in the enzymatic systems responsible for catabolism of active oxygen species.

 EncycloWine: Encyclopedia for Wine Enthusiasts - Ripening
Ripening is a process in fruit such as grapes that causes them to become more edible and more suitable to make wine.
An important plant hormone involved with ripening is the chemical ethylene, a gas created by plants from the amino acid methionine.
If too few seeds in a multiseeded fruit are formed (by fertilization of the ovules), the flesh of the fruit may not develop in some areas, and ripening will be retarded or prevented.

 Determinate, delayed-ripening cherry tomato plants - Patent 5763742
The ripening inhibition reported in the tomato line Alcobaca has been shown to be caused by a mutation that is an allele of nor (Lobo et al.
The mutation Nr results in fruit that do not ripen fully (only to a pale orange) and may be the basis for the long shelf life of the variety Longkeeper.
As used herein, the terms "delayed-ripening" or "ripening-delayed" are used to refer to tomato plants which are heterozygous for an allele which inhibits the maturation of fruit of the plant.

 Methods for cervical ripening and induction of labor - Cover Article American Family Physician - Find Articles
The duration of labor is inversely correlated with the Bishop score; a score that exceeds 8 describes the patient most likely to achieve a successful vaginal birth.
The risks and benefits of these agents are still unknown because the quality of evidence is based on a long tradition of use by a certain population (6) and anecdotal case reports.
The only conclusion that can be made at this time is that the role of herbal remedies in cervical ripening or labor induction is still uncertain.
