How does sleep affect brain performance?
Researchers from the Bar-Ilan University of Israel learned that sleep deprivation has a negative impact on aging and leads to the development of brain disorders. In reference to animal behavior observation, sleep also significantly affects brain performance among humans. In a study published in the Nature Communications journal, the researchers used 3D time-lapse imaging techniques to measure the effects of sleep deprivation. The results of the study showed that neurons require sleep for them to function properly and coherently. The results also showed that sleep deprivation results in DNA damage, such as oxidative stress, and adversely affects the brain’s ability to function.  The lead researchers concluded that the loopholes of brain activity are remedied when we sleep at night, such as in the case of the zebrafish they observed, according to Science Daily. Using a high-resolution microscope and applying controlled body tests, they also found that one of the main functions of sleep is to maintain the nuclear makeup of brain cells that’s responsible for constant neuron activity. In analyzing the fish, they found that animals sleep in order to preserve their DNA composition. Hence, the researchers said that sleep deprivation could really affect aging and lead to brain disorders. Furthermore, the study found that constant sleep deprivation could lead to the production of cancer cells, making the body unable to detoxify itself from DNA damage. The researchers noted that brain chromosomes are surprisingly more active during the night especially when the body is at rest. Thus, they concluded that the damage repair is also directly associated with physiological relevance to the entire body. On the other hand, Daily Mail pointed out the causes of sleep deprivation which could hinder the DNA repair process. When a person is stressed, they feel anxious and this prevents the body from acquiring enough sleep required to improve cognitive abilities. The outlet also stressed that establishing a frequent sleep routine could help improve the ability of a person to spend more time sleeping than just lying around. Listening to calming music and visualizing happy pleasant thoughts also promote a healthy sleep, thereby preventing aging and brain disorders from developing. Source: Medical Daily/MSN AH

Nazim Uddin still can’t sleep at night due to pain from splinters
Although more than a decade is over but the verdict of August 21 grenade attack case is yet to be implemented. Nazim Uddin from Bhairab is the eyewitness and victim of that gruesome attack. He is living with pains from numbers of splinters in his whole body. It is known that, Nazim Uddin, son of Mofiz Uddin from Akbar Nagar village of Bhairab upazila went to the rally of August 21, 2004 in response to the call of the then women’s affairs secretary of Awami League and wife of late president Zillur Rahman, Ivy Rahman. He joined the anti terrorism rally organized on that day. At one stage Ivy Rahman wanted to take some water. So he stepped towards a shop to buy a bottle of water and then he stunned by the huge bursting sound of grenades. Smoke was everywhere. After sometimes he was hit and became unconscious. Nazim Uddin was seriously wounded by the grenade attack. Later he was taken to Dhaka Medical College Hospital. There while primary treatment the physicians thought that he was dead. But he became conscious at one stage. Immediately he was shifted to Renal Hospital. As his condition deteriorated he was shifted to India for better treatment by incumbent Prime Minister Sheikh Hasina. After getting treatment for long period Nazim Uddin returned to the country. He was undergone four major surgeries in his chest and legs. But he was not fully recovered and lost his ability to work. Still there are numbers of splinters in his chest and both legs which need to remove on emergency basis. He cannot sleep at night due to pain. The pain increases during the winter. On the other hand he cannot move under sunlight. Itching sometimes create bleeding. Nazim Uddin is passing a painful life due to scarcity of money. Victim and eyewitness of August 21 grenade attack case, Nazim Uddin said, many died in the gruesome attack and some are passing their lives with pains. Most of the injured people cannot avail treatment due to financial support. They are going to the path of death slowly. So he wants proper treatment and rehabilitation for the injured and also wants to see capital punishment for the involved in the attack. AH
