The optic nerve diameter (OND) was measured using a high-resolution digital dedicated small-parts real time ultrasound machine (Sonoace 5500; Medicol, Medison, Miami, FL, USA) with a high frequency (10-MHz) linear array transducer. Subjects were in supine position and were asked to keep their eyes closed and still. Coupling gel was placed on the closed eye lid with the transducer softly placed over the upper temporal eyelid in an axial plane. The OND was measured perpendicular to the vertical axis of the scanning plane as a horizontal distance between the two walls of the nerve sheath. The height and weight of the subjects were determined using a meter rule and a weighing scale.Results: The mean optic nerve sheath diameter of males and females was 4.2 ± 0.13 mm. It ranged from 4.0 to 4.45 mm. The optic nerve sheath diameter of males was not significantly different from that of females (p = 0.345). No significant difference between the mean OND of both eyes (p = 0.345). Body mass index and age did not have any association with OND (r = 0.017, 0.034), the data were normally distributed.Conclusion: Optic nerve diameter of apparently normal Nigerian adults ranges from 4.0 to 4.5 mm. Values outside this range may demand further evaluation in the study population.","PeriodicalId":12516,"journal":{"name":"Global Journal of Pure and Applied Sciences","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88916015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some specific physicochemical characteristics, such as temperature, hardness, alkalinity, salinity, TDS, TSS, pH and conductivity which are known to influence the interactions and dynamics of trace metal loads in water bodies were also determined. The result of the analysis indicated significant monthly variation of these parameters for the six months. Monthly summary statistics revealed a few seasonal patterns that echoed the hydrologic regime. During the short dry season in August–September period, all the sampled stream channels had lower levels of Cd, Ni, Zn, Cu Cr, Pb and Fe. Salinity, for instance, correlated strongly (p<0.05) with Cu (0.70); Cr (0.56); Ni (0.72); nitrate (0.61) and Na (0.49).

Development and survival of incubated eggs, larval stages I, II and pupae to adult emergence were highest between 22.2 and 28.8 °C and resistant to temperatures below and above that range. Third larva stage showed a difference, with emergence higher at 15.6 than at 22.2 °C. No adult fly emerged at 36.1 °C. The male and female flies of ages 0, 5, 10, 15 and 20 days were divided into batches (n = 20). Batches of male and female flies was incubated separately for eight hours and further monitored for 72 hours in the laboratory for survival. Adult males and females survived within 15.6 – 28.8 °C than at higher temperatures irrespective of the ages; 36.1 °C had a lethal effect on the flies. There was no significant difference (P>0.05) in the survival of adult flies at incubation and after 72 hours of exposure. The results suggest that the effect of temperature depends upon the stage of development of Chrysomya chloropyga. Temperature is fundamental in the development of C. chloropyga and should be considered during PMI determination and in the formulation of control strategies.","PeriodicalId":12516,"journal":{"name":"Global Journal of Pure and Applied Sciences","volume":"60 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83728899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The crude extracts were dissolved in di-methylsulfoxide. The phytochemical constituents of the crude extracts were accessed and compared. Clinical isolates under aseptic conditions were collected from the Medical Microbiology Laboratory, University of Port Harcourt Teaching Hospital and further morphological and biochemical tests were carried out to identify this clinical isolates as; Staphylococcus sp., Escherichia sp., Pseudomonas sp., Klebsiella sp., Streptococcus sp and Candida sp. Inoculums were prepared and adjusted to 0.5ml Mc Farland standard of each test bacterium. It was spread onto sterile Muller Hinton Agar plates so as to achieve even growth. The plates were allowed to dry and a sterile cork borer (6.0mm diameter) was used to bore wells in the agar plates. Ofloxacine and Fluconazole was used as bacteria and fungi control respectively. The crude yellow extracts exhibited inhibitory activities that were found to be higher than crude white and ivory colored extract on all the test organisms. Despite the crude yellow extract exhibited higher inhibitory activities than the other extracts; the antibacterial activity was low in 10-1 to 10-4 dilutions for some bacteria. The crude extracts revealed the presence of Alkaloids, flavonoids, Cardiac glycosides, saponnin, and carbohydrates. Anthraquinnone and phlobatannin were absent in the extracts. This study also revealed that shea butter has no anti-helminth effect after 24hours exposure of the eggs of Ascaris lumbricoides and Trichuris trichuria in the shea oil sample rather; the DMSO used as control killed the eggs. This calls for further investigation.","PeriodicalId":12516,"journal":{"name":"Global Journal of Pure and Applied Sciences","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79274905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drainage pattern is mainly dendritic type. It is observed that the drainage density value is low which indicates the basin is highly permeable subsoil and thick vegetative cover. The elongation ratio value reveals that the basin is strongly elongated and stream abstraction process constrained by heterogeneous geologic materials.

Descriptive statistics shows that, with the exception of silt and clay other parameters analysed decreased in value after flooding, while the predominant textual class of the soil is clay-loam. The PCA for March and September sampling periods extracted three components each which explained 84.10% and 78.90% respectively of the total variance. Cluster analysis yielded five distinct clusters for March: cluster 1 (K, Ca, EA, and pH); cluster 2 (OM, CEC, TN, Silt content, Clay content, and OC); cluster 3 (Na); cluster 4 (P), and cluster 5 (Mg and Sand content); and five separate clusters for September. From DA, seven variables (pH, OC, OM, TN, P, K and Mg) were the most significant parameters which accounted for the expected spatial/temporal variations in the soil of March, while CEC, Na, Ca, silt, sand and clay become an important discriminator in September. Flood has significant influence on the soil of the study area as level and distribution of the parameters changed from March to September.","PeriodicalId":12516,"journal":{"name":"Global Journal of Pure and Applied Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88574665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
