Gender Selection

In theory, with every pregnancy a couple should have a 50/50 chance of having a boy or a girl. And while those odds could dictate a family producing children of predominately one gender, from the standpoint of statistics and probability, the genders should be split equally. And yet, there are many families with children of only one gender, even in larger families with upwards of 3 children or more. It's difficult to say whatever this is due to genetics, the nature of the father's sperm or some other factor, but there are many families who seem to be able to produce one. So it seems that while the genders should be equally split quantitatively, in individual families the numbers might be completely skewed to favor one gender over another.

But the desire to have a child of a particular gender is not the only circumstance in which gender selection comes into play. There are many genetic diseases that are carried on one specific gender and parents wishing to avoid producing a child with that disease may prefer to have children of only one gender.

Regardless of the motivation for wanting a child of a particular gender or the cause of the difficulty in having one, gender selection techniques are available. Backed by years of research, these gender selection techniques are safe and effective. Gender selection can guarantee families the child they always held for. Gender selection can also guarantee a child who gender results it from inheriting a gender-based genetic disorder. Parents should not have to rely on statistics or probability. With gender selection, couples can produce healthy babies of their chosen gender and the family of their dreams.

Using the Ericsson Method

If you want a boy, you select sperm containing the Y chromosome, so that during fertilization, the sperm's Y chromosome will pair up with the egg's X chromosome. If you want a girl, you select sperm containing the X chromosome, so that during fertilization, the sperm's X chromosome will pair up with the egg's X chromosome.

IVF / PGD Technique

After ovarian stimulation, eggs are removed from the mother. These eggs are fertilized in the laboratory using the father's sperm. After cell division, the embryos are checked for their sex. Only the embryos of the chosen gender are transferred back to the mother.

Technological Methods of Baby Sex Selection

The major advantage of using technology in gender selection is that it's generally much, much more accurate in helping you choose the gender than natural techniques are. On the downsides, scientific procedures are much more expensive and often involve methods like in vitro fertilization, which is a turn off for people interested in conceiving naturally.

The most successful method of gender selection is PGD (preimplantation genetic diagnosis). It's effectively a way of choosing the gender of the baby before an embryo is implanted via in vitro fertilization. It's the only way to know for sure you'll be getting a boy or girl, because the gender is known before the embryo is implanted. Other scientific methods generally involve a manipulating sperm count to favor the chances of conception towards a boy or a girl, because it is the X or Y chromosome carried by sperm which determinates the gender of a baby.

Common Skin Pigmentation Disorders

We are all born with clear and flawless skin. But in due course of time, there can be various skin disorders. This is because as we grow and get outside, a number of external factors begin to affect us. Pollution, sun exposure, environmental conditions all take toll on the skin. And because of this your body may lower the production of melanin or the blood vessels will not function properly. Also, there can be a number of other disorders that you may develop due to excessive exposure to sunlight. Tanning and sun burns being the most common, there are plenty of complications after it

Here are some common skin pigmentation disorders:

Albinism
Albinism is a genetic disorder that is caused by the lack or complete absence of pigmentation in the skin. The body contains an abnormal gene that precedes the production of melanin. There may not be a complete cure for albinism but individuals suffering from it should take necessary precautions. They should apply sunscreen all through the day be it indoors or outdoors. This is due due to lack of melanin, the skin becomes extremely vulnerable to sun damage risking them to diseases like skin cancer. Try the all new Nia 24 Sun Damage Prevention SPF 30. It's a duo-action sun damage prevention solution that contains 100% mineral sunscreen in a weightless, oil-free lotion. It is instantly absorbed by the skin.

Melasma
Also known as chloasma, this particular disease shows as brown patches and tan marks across the face. Both men and women are equally intolerable to it though some term it as a 'pregnancy mask.' But the great news is it is not permanent and can be treated very easily. And what's more, you can treat it yourself by using essential skin care products. Obagi Nu-Derm Blender Promotes improvement at the cellular level and gets you an even skin color. You can also use Onagi Nu-derm Clear, a skin bleaching and Corrector Cream with 4% Hydroquinonoe USP that corrects uneven skin tone and cures age spots.

Loss of Pigmentation due to Skin Damage
Whenever there is a skin-damage like burns, boils, blisters etc. it leaves behind a scar after it dries up. And there may be a loss of pigmentation in the affected area. But then again, an easy way to get rid of them is using appropriate cosmetics and skin care products. Obagi C-Clarifying Serum contains 4% hydroquinone + vitamin C serum along with L-ascorbic acid. While vitamin C penetrates the dermis to reduce melanosome activity the solution promotes an even skin tone and provides potent antioxidant therapy.

Vitiligo
This skin disorder happens when melanocytes get destroyed because resulting in the formation of white patches on the skin. Certain diseases are linked to vitiligo like diabetes but there is no sure evidence about it. Sometimes it also happens because of lack of calcium. There is no cure for vitiligo as such but you can undergo several treatments to get rid of the white patches.

Whatever be the disorder, there are several skin care treatments available to rectify the results!

Chromosome instability in cancer development



Dr Ian Hickson explains how understanding chromosomal instability could allow for new targets and drugs that would keep the chromosomes stable by exploiting defects in genes and targeting the instability.

Dr Hickson’s current research involves the genetic disorder Bloom syndrome, a rare condition that has the potential to develop all types of cancers. Interestingly Bloom syndrome is the only genetic disease that is associated with all types of cancer.
