Identification and assessment of Modifiable and Non-Modifiable risk factors and oxidative stress in pathophysiology of stroke diseases- a review

2021-03-04T09:13:56+00:00

The aim of this review is the identifying the main factors risk factors and manifesting the role of oxidative stress as factors associated with stroke diseases. 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.

An extended distribution of Non-Native Tree species Muntingia calabura L. in Rajshahi, Bangladesh

2021-05-04T08:46:34+00:00

Muntingia calabura 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 Muntingia calabura 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.

Gender Comparison Of Alpha-Fetoprotein, CD4, Albumin and Some Liver Enzymes in Symptomatic HIV Subjects on Antiretroviral Therapy

The emergence of Human Immunodeficiency Virus (HIV) has remained an issue of global discuss till date as it continues to invade and ravage the world’s population despite the efforts been made globally at tackling the impact of the virus. This is a case controlled study designed to comparatively evaluate the alpha-fetoprotein, CD4⁺ T-cell count, albumin and some liver enzymes activities in male and female symptomatic HIV subjects on antiretroviral therapy in NAUTH Nnewi, South Eastern Nigeria. A total of seventy one (71) participants who were aged between 18 and 60 years attending the voluntary counseling and testing unit (VCT) and antiretroviral therapy unit (ART) of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi as well as 25 control subjects were randomly recruited for the study . CD4 count, alpha fetoprotein (AFP), albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase activities were estimated by standard laboratory methods. Results showed no significant differences in the mean values of AFP, CD4 count, albumin, ALT, AST and ALP compared between male and female symptomatic HIV infected individuals on ART and symptomatic HIV infected male and female subjects NOT on ART (p>0.05) respectively. Also, there was no significant difference in ALT and AST activities when compared between male and female HIV seronegative control (p>0.05) although ALP activity was significantly higher in female control subjects than in males (p=0.01). This revealed no gender specific differences in mean values of alpha fetoprotein, albumin, CD4 T-cell count, and liver enzyme activities between male and female HIV infected symptomatic individuals on antiretroviral therapy and symptomatic HIV infected persons NOT on antiretroviral therapy.

Assessment of adsorption kinetics for removal Copper Ions from aqueous solutions using Egg Shells as a Bioabsorbent

2021-08-30T02:00:22+00:00

Adsorption process kinetics study showed the possibility of using egg shell as a natural adsorbent, and this has had a high effectiveness in eliminating ions of Cu ion from water solution. The experiments were conducted in a temperature range of 293 - 323 K, with the initial concentration of Cu ions of 5 mg/L and adsorbent of 5 mg/L. At during in experiments, pH Solution value was set to 6, and the amount of absorbed ions was determined the following time interactions: 10, 30, 40, 60, and 120 minutes. The experiments were conducted in an electric shaker, at 200 rpm speed.

The data the pseudo-second row model depends on the value of the correlation coefficient (R²), The results data suggest that this model describes the adsorption system well when the correlation coefficient R² > 0.900. which indicates that this model is more applicable and better describes the examined adsorption processes in this study and speed of interacting with adsorbent and active places present on the surface of the biosphere.
