It is very difficult to determine the cause of stroke but studies scientists have shown that some characteristics and non-modifiable factors of peoples played a major role in developing strokelike, age, Gender, Race and Heredity. Other modifiable risk factors includehypertension, Heart disease, Diabetes mellitus, Dyslipidemia and Obesity have also been associated with higher stroke incidence. On the other hand, studies support that oxidative stress is directly involved in the genesis and aggressiveness appearance of stroke. However, cerebral dysfunction like Ischaemia would be followed by reperfusion leads to increased production of free radicals which induce also oxidative stress. In conclusion, changing human behavior in life is the first way to prevent stroke disease; on the other hand, we suggest that antioxidants treatment has great benefits in improving patient health and decreasing the vascular complications of stroke.</p> 2021-03-04T09:13:18+00:00 ##submission.copyrightStatement## An extended distribution of Non-Native Tree species Muntingia calabura L. in Rajshahi, Bangladesh 2021-05-04T08:46:34+00:00 Mohammad Tarikul Hasan <p><em>Muntingia calabura</em>&nbsp;is a fast growing evergreen tree ‍and is indigenous to southern Mexico, Central America, tropical South America, the Greater Antilles, St. Vincent and Trinidad. It is now widespread and naturalized in Southeast Asia, Australia, and in islands of the Pacific Ocean due to its ability to disperse by bats and birds. In Bangladesh it is being cultivated in homesteads in some places especially in urban area as a sweet minor edible fruits. During this exploration, three plants of <em>Muntingia calabura</em> found in Rajshahi city. It is reported here as an addition to the Flora of Rajshahi district. This paper also envisages plant description, photographs and Figure of herbarium sheet are provided to facilitate easy identification.</p> 2021-05-04T08:46:34+00:00 ##submission.copyrightStatement##
