coupling

 [kup´ling]
in electrocardiography, precise linkage of an ectopic complex to the preceding beat each time it occurs.

cou·pling

(kŭp'ling),
1. The result of the repeated pairing of a normal sinus beat with a ventricular extrasystole.
2.
3. A condition in which one or more products of a reaction are the subsequent reactants (or substrates) of a second reaction.
4. The covalent bonding of one molecular entity to another.
5. An interaction between different parts of a system, for example, between groups in a molecule.
6. The linking of electron trnasport to oxidative phosphorylation.

coupling

/coup·ling/ (kup´ling)
1. the joining together of two things.
2. in genetics, the occurrence on the same chromosome in a double heterozygote of the two mutant alleles of interest.
3. in cardiology, serial occurrence of a normal heartbeat followed closely by a premature beat.

coupling

(kŭp′lĭng)
n.
The body part of a four-footed animal that connects the hindquarters to the forequarters.

coupling

[kup′ling]
Etymology: L, copula, bonding
1 the act of coming together, joining, or pairing.
2 (in genetics) the situation in linked inheritance in which the nonalleles of two or more mutant genes are located on the same chromosome and are close enough that they are likely to be inherited together.
3 (in radiation therapy) the efficiency of transfer of power from an applicator to the treatment site. Compare repulsion. See also cis configuration.
4 (in cardiology) the regular occurrence of a premature beat.

cou·pling

(kŭp'ling)
1. The repeated pairing of a normal sinus beat with a ventricular extrasystole.
2. A condition in which one or more products of a reaction are the subsequent reactants (or substrates) of a second reaction.

coupling

an arrangement in a double HETEROZYGOTE where WILD TYPE alleles of two genes are located on one chromosome with MUTANT alleles of these two genes on the other HOMOLOGOUS CHROMOSOME. Such an arrangement of linked genes is usually referred to as in coupling (see Fig. 122 ). Such arrangements are important when considering the implications of GENETIC LINKAGE. Compare REPULSION.

coupling

1. in an animal's conformation, the distance between the top of the scapulae to the hip joints.
2. in ultrasonography, the transmission of sounds from the transducer into the tissues being examined. A medium such as a gel or mineral oil is used to exclude air from between the two surfaces.

Patient discussion about coupling

Q. help program for infertil couple MY NAME IS ALEX AND I'M 44 YEARDS OLD AND MY WIFE IS NILDA AND SHE IS 41 YEARS OLD

A. Your infertility treatment plan will depend on the cause or causes behind your infertility. Infertility treatment also depends on whether the problem is from the woman’s side, the man’s side, both sides, or remains unexplained.The good news is that 85% to 90% of couples dealing with infertility are treated with low-tech treatments, like medication or surgery, with less than 3% being treated by Assisted Reproductive Technologies, like IVF. Of those treated for infertility, two-thirds will go onto have a baby. A common cause of infertility in women, ovulation disorders account for about 25% of female factor infertility cases. The first line of treatment for most women with ovulation problems is through medication. Fertility drugs can help a woman ovulate 80% of the time.

Q. what are the must test that a couple need to go through during pregnancy?

A. It depends on many things, including age, ethnicity (e.g. genetic counseling for Ashkenazi Jews), geographical areas, habits etc.

General screening include laboratory tests for blood type (including Rh type), hemoglobin levels, rubella immunity, syphilis, hepatitis B and chlamydia testing (infectious agents that may cause malformations in the fetus),

Ultrasound screening, although not proven to reduce the overall outcome, is usually offered during the first trimester in order to diagnose abnormalities of the fetus. Down syndrome screening is also usually offered to all pregnant women, although the risk is substantially higher mainly in older ages of the mother.

There are many more tests, and you may consult your doctor (e.g. gynecologist) to learn more about this subject.

Q. What are the steps we as a couple go through during pregnancy? any one experienced that?? :)how does it feel

A. Dunno about steps, it just naturally progresses. You have decisions to make about nutritionals that you will take, where you want to birth your baby, if you want to experience an amazing natural drug free birth, or the other, if you want an epesiotomy, or not, who you want to be there, and if you will circumcise if you have a boy, amongst many others. My eldest daughter assumed everything would go well and didn't do her research and ended up having a c-section. She then made up for lost time, and told her sister to go for unassisted childbirth. I was able to support her because of my experience with goats and the difference nutritionals and minerals made in how successful the goats were in kidding. Not only successful, but a totally amazing experience! Even brought healing to me for the trauma I experienced birthing my own 4 babies. The pic is of the uc grandbaby. I highly recommend uc.
