Constructed wetlands (CWs) are an aesthetic and sustainable form to treat wastewater, however, their performance can be increased by improving a number of factors. The pilot-scale hybrid constructed wetland (CW) system was the combination of constructed floating treatment wetlands (CFWs) and horizontal subsurface flow constructed wetlands (HSFCWs); operated for a year and covered all seasons. The research was conducted to investigate the performance of the CW system regarding water depth, spatial, and seasonal removal of pollutants. Nine economical plants species were selected and divided into four groups to grow in CW-I to CW-IV, respectively. Removal increased along the bed and most of the total phosphorus (TP) removal occurred in the second bed, whereas total nitrogen (TN) and ammonium (NH4) removal were associated with the plant root system and biomass. Optimum removal of nutrients with respect to water depth was at 35 cm. TN and NH4 removal patterns were similar in different CWs. TN and NH4 removal were higher during summer compared to winter; only CW-IV showed the opposite trend.

The main purpose of this study was to find out a possible association between ABO blood groups or Rh and diabetes mellitus (DM) in the local population of eight (8) different towns of Karachi, Pakistan. For this purpose a survey was carried out in Karachi to have a practical observation of these towns during the period of 9 months from June 2019 to Feb. 2020. Out of eighteen (18) towns of Karachi, samples (N= 584) were collected from only eight (8) Towns of Karachi and gave a code-number to each town. Diabetic group sample was (n1=432) & pre-diabetes sample was (n2 =152). A standard Abbot Company Glucometer for Random Blood Sugar (RBS) and Fasting Blood Sugar (FBS) tests, standard blood anti sera were used for ABO/Rh blood type. Health assessment techniques were performed ethically by taking informed consent from all registered subjects. Finally data was analyzed by SPSS version 20.0. In our current study, the comparison of ABO blood groups frequencies between diabetic and pre-diabetic individuals were carried out. The percentage values of blood Group-B as given as: (32% in DM vs. 31% in pre-diabetics), followed by blood Group-O as: (18% in DM vs. 11% in pre-diabetics). Contrary to Group-“B” & “O”, blood Group-A and Group-AB were distribution percentage higher pre-diabetic as compared to DM patients, as given as: Group-A (32% in pre-diabetics vs. 26% in DM) & Group-AB (26% in pre-diabetics vs. 24% in diabetic’s patients). In addition, percentage distribution of Rh system was also calculated, in which Rh+ve Group was high and more common in DM patients as compared to pre-diabetics; numerically given as: Rh+ve Group (80% in DM vs. 72% in pre-diabetics). Different views and dimensions of the research topic were studied through literature support, some have found no any association and some established a positive association still some were not clear in making a solid conclusion. It is concluded that DM has a positive correlation with ABO blood groups, and people with Group-B have increased susceptibility to DM disease.

The assessment of the comparative effect of biosal (phytopesticide), deltamethrin, and lambda-cyhalothrin (pyrethroids) were made against two fodder pests, Hermolaus modestus and Hermolaus ocimumi by filter paper impregnation method. The activity of total protein contents, GPT (glutamic-pyruvic transaminase) and GOT (glutamic oxaloacetate transaminase) were affected in Hermolaus modestus and Hermolaus ocimumi against biosal, deltamethrin, and lambda cyhalothrin. The activity of total protein contents in H. modestus was 31.053%, 4.607%, and 24.575%, against biosal, deltamethrin, and lambda-cyhalothrin, respectively. The activity of total protein contents was observed as 24.202%, 15.25%, and 56.036% against deltamethrin, lambda-cyhalothrin, and biosal, respectively in H. ocimumi. The activity of GOT was observed as 98.675% for biosal 33.95% for deltamethrin and 83.619% for lambda-cyhalothrin in H. modestus. The GOT activity was estimated in H. ocimumi as 78.831%, 47.645%, and 71.287% against biosal, deltamethrin, and lambda-cyhalothrin, respectively. The efficacy of GPT enzyme against biosal, deltamethrin, and lambda-cyhalothrin was calculated as 89.26%, 73.07%, and 47.58%, respectively in H. modestus. The H. ocimumi showed GPT activity as 77.58% for biosal, 68.84% for deltamethrin, and 52.67% for lambda-cyhalothrin, respectively.

Binders are the products that are used to bind, glue or hold the various feed ingredients together in order to maintain pellet integrity. For aqua-culturists, feed manufacturing is an expensive exercise due to the high cost of ingredients along with traditional artificial binders. The use of grain starches as aqua feed binders have advantages which include availability of that binder, nutritional contribution, and minimization of feed cost. A research trial was conducted to test physical properties such as palatability, water stability, dustiness, friability, settling velocity and floatation time of locally available starch i.e. wheat gluten, pea starch and guar gum and to assist their incorporation in on-farm aqua feed. Results revealed that among these three starch, the starch from pea source was proved superior over other two (wheat gluten and guar gum) as all physical quality parameters (dustiness, water stability and friability) revealed better performance of pea starch except pelletability in which guar gum performed best. Although not a single diet proved best in case of flotation time (Tf) and settling velocity (Vset) at varying lengths (6mm, 9mm and 12 mm). This finding indicates the significance of suitable binders for optimal water pollution and sustainable aquaculture. The use of these binders i.e. wheat gluten, pea starch and guar gum in fish feed pellets may also reduce dependence on synthetic binders and minimizes cost.

This study determines the associations among serum lipid profiles, risk of cardiovascular disease, and persistent organic pollutants. Using Gas chromatography technique, the intensity of toxic pollutant residues in serum samples of Hypertensive patients were measured. Based on statistical analysis, the effects of different covariates namely pesticides, age, systolic blood pressure, diastolic blood pressure, and lipid profile duration was checked using the logistic regression model. Statistical computation was performed on SPSS 22.0. The P-values of F-Statistic for each lipid profile class are greater than 0.01 (1%), therefore we cannot reject the null hypothesis for all cases. The estimated coefficients, their standard errors, Wald Statistic, and odds ratio of the binary logistic regression model for different lipid profile parameters indicate if pesticides increase then the logit value of different lipid profile parameters changes from -0.46 to -0.246 except LDL which increases by 0.135. The study reports a significantly increased threat of cardiovascular disease with increased concentrations of toxic pollutants.
