English rivers waters – Substances blocking fertility
English rivers waters – Substances blocking fertility – British scientists claim that in the waters of
the English rivers is a group of substances blocking the male sex hormone testosterone.
Thus reducing fertility in men. After examining fished out of the rivers fishes.
It turned out that these compounds stimulate the development of female characteristics in males.
Threat associated with stress
Threat associated with stress – Stress arising through work or school, can lead to serious health problems. Such as cardiovascular diseases or the development of depression. Engineers from the lab ETH Zurich have developed in connection with this small device that allows you to measure stress levels. The instrument combines the measurement of skin conductance, heart rate and breathing with the measurement of stress hormones in saliva.
Left-handedness two types
Left-handedness two types – Today we distinguish between left-handedness:
- genetic, occurring in patients whose left-handedness is genetically programmed,
According to an earlier theory neuropsychologist Norman Geschwind (1926-1984) the probability of left-handedness is more, if the fetus was exposed to increased concentrations of the male hormone testosterone, which affects the development of the cerebral hemispheres. This theory may explain why in the euro-american society among left-handers are more men (12%) than women (8%).
- pathological, the cause is the dominance of one cerebral hemisphere,
According to another theory, left-handedness is caused by problems during labor, as a result of oxygen deprivation causes damage to the brain. According to statistics among left-handers who have had complications during childbirth, 30% are mentally retarded.
Neurohormones – Produced by the nervous tissue
Neurohormones – Hormones produced by the nervous tissue, for example: Acetylcholine, adrenaline, oxytocin, serotonin, melanotropin, vasopressin. They perform important functions in the body, and some are used in medicine.
Addictive sunbathing – Causes endorphin production
Addictive sunbathing – The need exposure to the Sun, as the most important source of vitamin D, we encoded in the genes. UV radiation causes the body’s production of endorphins. The hormones of happiness, of which we can be quite addictive.
Cardiovascular disease risk – Higher among bald men
Cardiovascular disease risk – Higher among bald men. Up to about 1/3, compared to the other men. Tests on 37 thousand. men carried Japanese scientists. Hair loss depends on the activity of male hormones, which also accelerate hardening of the blood vessels, or the effects of atherosclerosis.
Nucleus-cells brain – Complex nano composite body
Nucleus-cells brain – Complex nano composite body – In fact, every cell in the human body operates as a complex nano composite body. It is assumed nutrients. It produces a new protein. And also uses the nerve pathways and hormonal to maintain constant contact with the “co tribal“. Most of the cells has a nucleus, which is a kind of one’s brain, which are stored genetic information and decisions. There are also “brainless“ cells containing nuclei. These include for example. Red blood cells in mammals.
Impregnates – Substances with incredible properties
Impregnates – These substances have incredible properties – repel water and fat, protect against staining different materials. However, many studies have shown that the trace amounts found in our blood. Most preservatives are perfluorocarbons (PFCs), marked abbreviations PFOS and PFOA. Their molecules are extremely durable, so they can circulate in the environment for years. In animals can disrupt hormone levels and cause cancer. In humans, these substances can lead to thyroid disease and improve cholesterol levels.
