MONDAY, April 30 (HealthDay News) -- Stress experienced by a mother during the first trimester of pregnancy can lead to iron deficiency in her newborn, putting the infant at risk for physical and mental development delays, a new study says. Iron is important in organ-system development, especially for the brain. Risk f... |

The World of Plants The existence of plants is essential for the survival of living things on the earth. For the importance of this sentence to be fully grasped, we |
must ask: "What are the most important elements for human life?" Of course, basic needs such as oxygen, water, and nourishment come to mind as the answers to this question. |
And green plants are the most important factor in ensuring the balance of these basic needs on the earth. And there are other balances in the world, of great importance |
to all living things, not just human beings, such as temperature control and maintaining the correct proportion of gases in the atmosphere, and again it is green plants which maintain |
the entire equilibrium. And the activities of green plants do not end there. As is known, the main source of energy for life on earth is the Sun. But human |
beings and animals are unable to make direct use of solar energy, because their bodies lack the systems to use this energy as it is. For this reason solar energy |
can reach human beings and animals as usable energy only through the food produced by plants. For example, while sipping tea, we are actually sipping solar energy, and as we |
eat bread, we are munching solar energy. The strength in our muscles is really nothing other than solar energy in a different form. Plants store this form of energy for |
us in the molecules in their bodies by carrying out complicated processes. The position for animals is no different from that of human beings. They are fed by plants, deriving |
solar energy from the plants' energy, which they store in packets. Plants being able to produce their own nutrition and maintain themselves, in contrast to other living things, is due |
to their cell structure, which enables them to employ solar energy directly, unlike human or animal cells. With the help of this structure, plant cells turn energy from the sun |
into energy which people and animals can absorb through nutrition. They store this energy as food through the special procesesses concealed in their structure. These processes are collectively known as |
photosynthesis. The necessary mechanism, or more accurately the miniature factory, by means of which plants are able to carry out photosynthesis, is found in their leaves. The transportation system, with |
its own very special features, for carrying necessary materials such as minerals and water, functions within plants' stems and roots. The reproductive system too has been specially designed in every |
species of plant. There are complex structures within each and every one of these mechanisms. And these mechanisms function in connection with one another. If one is missing, the others |
cannot carry out their tasks. As an example let us take a plant which just lacks a transport system. It is impossible for such a plant to carry out photosynthesis, |
because the vessels necessary to carry the essential water are missing. Even if the plant managed to produce food, it would be unable to transport this to other parts of |
the body, and would eventually die. As in this example, all the systems present in a plant are obliged to function flawlessly. Any flaws or defects in the existing structure |
will mean that the plant cannot carry out its functions, and this will result in the death of the plant and the disappearance of the species. When these structures are |
studied in detail and in depth in the chapters that follow, a most complex and quite flawless design will emerge. When the variety of plants in the world is considered |
and evaluated, these extraordinary structures seem even more striking. There are more than 500,000 types of plant in the world. And each species possesses its own special planning within itself |
and features particular to that species. Together with the same perfect basic systems found in all of them, there is also an unparalleled diversity in terms of reproductive systems, defence |
mechanisms, colour, and design. The only unchanging thing in all this is the reality that the parts of the plants (leaves, roots, stems) and many other mechanisms, must exist at |
once and with no defects so that the general system, the body, can function. Modern scientists attribute to such systems an "irreducible complexity." In the same way that a motor |
will not work if one of its cogs is missing, in plants the absence of just one system, or a single functional failure in any one of the parts of |
the system, will lead to the death of the plant. All of a plant's systems have this feature of irreducible complexity. The complex systems, which must all be present at |
the same time, and this unbelievable variety bring to mind the question: "How did these perfect systems in plants emerge?" Once again, let us ask some questions to find the |
answer to this one. Let us think how the functioning of the most important and best known of the mechanisms in plants, photosynthesis, and the transport systems linked to it, |
came about. Can the trees and flowers which we see all around us at all times have themselves formed such perfect systems as to bring about a phenomenon such as |
photosynthesis, some parts of which are still not fully understood, in their own bodies? Did plants choose to use carbon dioxide (CO2), of the gases in the air, to produce |
food? Did they themselves determine the amount of CO2 they would use? Could plants have designed those mechanisms which make up the root system and which enable them to take |
the materials necessary for photosynthesis from the soil? Did plants bring about a transport system where different types of tubes are used for transporting nutrients and water? As ever, defenders |
of the theory of evolution searching for an answer to the question of how plants emerged have resorted to "chance" as their only remedy. They have claimed that from one |
species of plant which came about by chance, an infinite variety of plants have emerged, again by chance, and that features such as smell, taste, and colour, particular to each |
species, again came about by chance. But they have been unable to give any scientific proof of these claims. Evolutionists explain moss turning into a strawberry plant, or a poplar, |
or a rose bush, by saying that conditions brought about by chance differentiated them. Whereas when just one plant cell is observed, a system so complex will be seen as |
could not have come about by minute changes over time. This complex system and other mechanisms in plants definitively disprove the coincidence scenarios put forward as evolutionist logic. In this |
situation just one result emerges. Every structure in plants has been specially planned and designed. And this shows us that there is a Superior Intelligence which drew up this flawless |
plan. And the owner of this superior intelligence, God, the Lord of all the worlds, shows proofs of His flawless creation to human beings. God announces His dominion over living |

- slide 1 of 4 Definition of a Mid-Life Crisis or Depression The type of depression that accompanies a mid-life crisis is generally caused by internal factors rather than external influences. In some cases, however, menopause is a contributing factor. |
A typical mid-life depression will manifest differently in men and women with some of the symptoms being as follows: - Affairs with younger women - Anger and irritability - Hostility and conflict - Demands respect - Restless and agitated - |
Afraid of speaking out doubts and fears - Fear of failure - Self treats with TV, alcohol, sport and sex - Loss of libido - Feelings of sadness and worthlessness - Avoids conflict - Feels like a failure - Withdraws |
from social contact - Feelings of guilt and lack of self respect - Self treats with food, friends and love - Sleep problems A mid-life crisis usually lasts for a few years and results in permanent changes in lifestyle. Whether |
these are positive or negative is an individual choice. - slide 2 of 4 Identifying a Mid-Life Crisis Depression in mid-life often arises when a person is in their 40s or 50s. It is at this stage of life that |
men and women realize they are ageing and their physical strength and appearance will be declining gradually. This realization leads to some of the behavior that is often seen during a mid-life depression. Men tend to have affairs and women |
may indulge in plastic surgery and dramatic keep-fit programs. By their 40s, most men and women are financially secure and established in a career. During a mid-life crisis they question if this is all there is to life and may |
feel bored and let down. Others may be disappointed with what they have achieved and frustrated by a loveless marriage. What they do at this point will determine how their lives will look in years to come. - slide 3 |
of 4 How to Overcome Depression and a Mid-Life Crisis There are a number of ways men and women can overcome a mid-life depression: - Visit your doctor for a checkup. This will determine if there are any health issues |
that need addressing. Some people with this type of depression benefit from a short course of antidepressant medication to tide them through difficult patches. Hormone replacement therapy can help women suffering from menopause-related depression. - Join the AA or a |
support group if you are struggling with addictions or are overindulging in food, alcohol, smoking, gambling or sex. It is easier to overcome these problems when sharing how they affect you with people who understand your struggles. - Confiding in |
a friend who you know experienced a mid-life depression can be helpful – especially if they had a positive outcome. Most people are more than willing to share their experiences and offer support to those going through something similar. - |
Regard a mid-life depression as an opportunity to re-evaluate goals, dreams and ambitions in life. Look at job satisfaction, leisure time and relationships, and if necessary, make some changes and plan for positive change. People who lose focus are more |
susceptible to depression and dreams give them something to reach for. - Accept that while ageing is a natural process, it doesn’t mean the end of enjoying life. There is nothing wrong with trying to improve matters by dieting, giving |
up smoking or exercising more, but there must be a realization that ageing does bring limitations and bodily changes. Wrinkles, weight gain and hair loss don’t have to signal the end of a fulfilling life or career. - Joining a |
gym, taking up a new hobby or meeting different people can give a fresh spark to life. Don’t sit at home feeling depressed. Get out and try a number of new activities until you find one that suits you. - |
Take some time out to do something different with your spouse or loved ones. This can be as simple as a day out in the country or a trip overseas. Marital difficulties commonly arise during a mid-life depression and working |
on love and togetherness can protect against this. - A mid-life depression may coincide with and be exacerbated by children leaving home. Use this as a time to do things you have always wanted to do but didn’t have the |
time, money or freedom to enjoy in your younger years. - Go on a mission trip or volunteer at a local soup kitchen or homeless shelter. Giving of yourself and your time can be extremely inspiring and will certainly change |
your perspective on life and your appreciation of your personal situation. There is no need to suffer in silence while experiencing mid-life depression. There is help available and individuals can make adjustments that transform this period of life into a |
Walker-Warburg syndrome is a congenital disorder of the central nervous system involving fatal neurological lesions. Multiple malformations of the brain, eyes, and muscle tissue distinguish WWS from similar malformation syndromes. |
It is also known by the acronym HARD +/- E syndrome (hydroencephalus, agyri, retinal dysplasia, plus or minus "e" for encephalocele). Affected individuals typically show a combination of severe brain, |
eye, and muscle defects. Multiple malformations of the brain include type II lissencephaly, a condition in which the brain lacks normal convolutions and is unusually smooth without folds. Eighty-four percent |
of the babies with WWS have macrocephaly (an enlarged head). In half of these cases, the macrocephaly is apparent at birth, and in a quarter of the cases it develops |
postnatally. Hydrocephalus, or excessive accumulation of cerebrospinal fluid around the brain, occurs in 95% of infants with WWS. This fluid fills abnormally large ventricles or spaces in the brain. Fifty |
percent of affected infants have an encephalocele, or gap in the skull that does not seal. The meninges or membranes that cover the brain may protrude through this gap. The |
formation of an encephalocele may be associated with the failure of the neural tube to close during development of the fetus. A malformed cerebellum characterizes the syndrome as well as |
distinct muscle abnormalities, including congenital muscular dystrophy. Ocular defects occur in 100% of infants with WWS. The most common are abnormally small eyes and retinal abnormalities, which arise from the |
improper development of the light sensitive area at the back of the eye. Cataracts may also be present and more than three quarters of the infants born with WWS have |
a defect in the anterior chamber of the eye. WWS syndrome leads to severely retarded mental development and is often lethal in infancy. WWS is inherited in an autosomal recessive |
pattern. Offspring of parents who have had one affected infant have a 25% chance of having WWS. The locations of the causitive genes remains unknown. WWS is extremely rare. Cases |
described in the literature cite siblings with WWS born to consanguineous (closely related) parents as well as cases in families not known to be at risk. Signs and symptoms Clinical |
signs include a malformed head, small eyes, cataracts, retinal abnormalities, and muscle weakness. An Prenatal ultrasound can reveal some of the brain anomalies associated with WWS, most commonly hydrocephalus and |
encephalocele. Lissencephaly can not be diagnosed prenatally as normal fetal brains appear smooth. After birth, diagnosis is made on the basis of physical features and ultrasound exams. MRI may be |
used to confirm the smooth brain feature or type II lissencephaly typical of WWS. Genetic analysis helps distinguish WWS from Fukuyama-type congenital muscular dystrophy (FCMD), which has numerous similar features. |
WWS can be differentiated from other syndromes that display hydrocephalus or encephalocele by the presence of eye abnormalities including retinal defects, cataracts and anterior chamber defects. Genetic testing for Fukuyama-type |
congenital muscular dystrophy distinguished this from WWS. Treatment and management The severe malformations of the brain defy treatment and many infants with WWS die within the first year of life. |
Supportive care is required to provide comfort and nursing needs. Seizures may be controlled with medication. Shunting may be required to control the hydrocephalus. A shunt or short plastic tube |
can be placed to divert the excess cerebral spinal fluid to another area of the body where it can ultimately be absorbed by the body. Genetic counseling is recommended for |
families at risk. Patients have a very limited life expectancy and the syndrome is generally considered lethal. Most patients die before the age of two. Menkes, John H., and Harvey |
