Answer:
None of these is true. (Ans e.)
Explanation:
C) Inhaled chemicals can irritate the throat or nose, damage the lungs, and enter through the lung to the bloodstream.
A) Skin is not impermeable in nature.
B) It is not safe to smoke around hazardous chemicals, as long as you wear gloves, because people can carry hazardous chemicals from cigarette smoke then releasing those compounds into non-smoking environments.
D) Alkaline can denature proteins, and they also break down fats in a process which is known as saponification. Burns from alkalines worse than burns from acids.
The laboratories have initiated Phase 1 clinical trials for the use of human pluripotent embryonic stem cells to treat paralyzed patients following spinal cord injury. The first step is to estimate the risks and tolerance of cell transplantation in a man. The fate of stem cells (multipotent or pluripotent) in the body is still poorly understood, and it is not excluded that uncontrolled cell multiplications occur, leading to the appearance of teratomas (tumor developed from pluripotent cells).
Advantages are:
* The safety of the cells also seems to be proven (in short term)
* Rats transplanted seven days after the injury had benefited from reactivation of myelinization of neurons by oligodendrocytes, attenuation of motor neuron loss and improvement of limb motor function.
The disadvantages are:
* Constraints of the ethical and religious order, it is necessary the consent and the approval of the donor and the recipient for the transplant to take place.
* The development of the technique is still new, there is a chance that side effects of the transplant appear years after the operation.
