The aim of this study was to evaluate the effect of nematodes infection on pcv value in Goats, Sheep, Horse, Donkey and Cattle’s. A total of 469 samples of faecal and blood were collected and transported to laboratory for detection of nematodes eggs and determine pcv value. The results obtained revealed that the higher prevalence rate of nematodes in study animals was on donkey when compared with others. The prevalence rate was higher in summer season than other autumn and winter. The effect of nematodes infection on PCV was found significantly lower (P<0.05) in Haemonchus spp, Trichostrongylus spp and Strongyloides spp when compared with Ascaris spp, Strongylus spp and Oxyuris spp.

This paper investigated the validity of Environmental Kuznets Curve (EKC) hypothesis in Nigeria using the Autoregressive Distributed Lag model (ARDL) estimated with the Ordinary Least Square (OLS) technique. The study used annual secondary data obtained from the World Bank indicators and the Central Bank of Nigeria for the period under review (1980-2018). Findings from the study support the validity of the EKC hypothesis for CO2 emissions. The study therefore recommended a harmonious environmental and economic policy mix that would engender greater income but keeping the protection of the environment a priority.

To determine the dangerous blood group ‘O’ donors o reoccurrence at the Federal Teaching Hospital, Abakaliki. One hundred (100) cell grouped and sero-typed blood group ‘0’ donors (94 males and 6 females) aged 18 and 45 years participated in this study between February and September 2007 at the Blood Bank(phlebotomy) section of the Teaching Hospital, Abakaliki after an informed consent. The presence of both the alpha (∝) and beta (β) haemolysin were determined using donors sera for reverse grouping. Haemolysin indicates the presence of haernolysis which is in the sera of the dangerous blood group ‘O’ donors. The study discovered that 36 male donors out of 100 donors studied were positive to haemolysin. This result was statistically analyzed using student’s t- test at 95% confidence interval with P value of 0.05. The numbers of haemolysin positive donors were significantly increased in comparison with the heamolysin negative donors (P< 0.05). This result pattern suggests a relatively high level of blood transfusion reactions in this part of the world. Screening test for dangerous group ‘O’ donors should be carried out routinely in blood transfusion laboratories to order to reduce the occurence of blood transfusion.

It is extraordinary, so the researchers title their article as ‘A Story about Time Travel.’ Anyway, the present researchers selected by random the 15 Chinese characters, named them from 0196 to 0210. The researchers translated the letters through two methods. One is to analyze the letter into several parts and to assemble each pronunciation. The other is to try to find its Korean pronunciation with separated several parts of the letter. It is possible to translate on several viewpoints. For example, 0207-1) Mae (to sell, 매; 買) is consisted of 'Mang'(the net, 망; 四) and 'zogae'(the shells, 조개; 貝). No, it is not. There is no "Mang zoyeo! 망 조여!". Therefore, our trial was not right. 0207-2). Mae (to sell, 매; 買) is consisted of Mang (the net, 망; 四), mog(the eye, 목; 目), yeodeolb(number eight, 여덟; 八). And its pronunciation is 'Mang mog yeodeolb'. And it will be reduced into 'Mang mo yeo', and then the pronunciation will be changed into "Mang moyeo! 망 모여!". Its meaning is "the net is collected!" 0207-3-1) Mae (to sell, 매; 買) is consisted of Mag (the net, 막; 四), mo(모; 目), yeo(여; 八). Here Mang (the net, 망; 四) was changed into 'Mag, 막', mo(目) and yeo(八) was assembled as 'mo yeo, 모여.' 'Mag moyeo!, 막 모여!' means "Come here(moyeo!) all of you!(Mag)" 0207-3-2) Mae(買) = M(四) + o(目) + yeo(八) = M o yeo = Moyeo → Mae, The sound of this Chinese character, Moyeo(모여), means "All of you, come here together!" 0207-4) Mae (to sell, 매; 買) is composed of 'Mag'(thoughtlessly, sufficiently, in any case, in any time; the net, 막; 四) and 'zuge!'(give it to the person!, 주게!; 貝). "Mag zuge! 막 주게!" means "(to the inferior person) Hey! Give it to them sufficiently!" Here, Mang(망) was changed into Mag(막), and 'zoge(조개)' was changed 'zuge!(주게!)' 0207-5) Mae (to sell, 매; 買) is consisted of Mag (막; 四) and zulgge(줄께; 貝). Here, Mang(망; 四) was changed into 'Mag(막)', and zoge(조개; 貝) was changed into 'zulgge(줄께)'. "Mag zulgge! 막 줄께!" means "I will give you something in a sufficient quantity!" (From our translation, this Chinese character of the sale[買] does not show the reality. But it only expresses a kind of apparent advertisement of the selling goods[買]. Because any seller would not give the matter to the buyer in cheap price).

Background and Aim: Pseudomonas aeruginosa is an important cause of opportunistic infections. Infection caused by Pseudomonas aeruginosa is often severe and threatening, and is difficult to treat due to its limited susceptibility to antimicrobial agents and resistance to treatment. Therefore, the aim of this study was to identify the molecular identification of CTX-M-1 genes in the P. aeruginosa strains isolated from urinary tract infections in Zanjan hospitals. Materials and Methods: In this descriptive-analytical study of the study of 289 cases of urinary tract infection in Zanjan medical centers in 2019, 100 isolates of P. aeruginosa were identified by standard bacteriological methods. Antibiotic susceptibility of the isolates was determined by disk diffusion method and ESBL-producing isolates were identified by combined disk method. The bacterial DNA was then extracted and studied by PCR using specific gene primers. Results: The most resistant to ampicillin (73%) and tetracycline (49%) were the most sensitive to amikacin (90%) and nitrofurantoin (89%), respectively. A total of 35 samples were identified as the final ESBL producer. 29 specimens of Pseudomonas bacteria had the CTX-M1 gene. Conclusion: The genes studied in this study were all located on the chromosome of P. aeruginosa bacteria. Therefore, further investigation of ESBL genes such as CTX-M1 gene seems necessary to control this bacterium.
