Toxico-histological Effects of Sublethal Concentrations of Lead Nitrate on the Gills of the African Catfish, Clarias gariepinus

170-175This study aimed to investigate the effects of subleathal lead doses on the histological architecture of gills in the freshwater African catfish, Clarias gariepinus. Results revealed three stages of changes after exposure to three doses of lead nitrate. The changes were mild in fish exposed to 16.12 mg/L of Pb (NO3)2 (stage I 20% of LC50) and severe in case of 40% of LC50 (stage II, 32.24 mg/L) and 60% of LC50 (stage III 48.37% mg/L) in comparison to control. The histological examination revealed normal architecture of gills in control fish. Normal gills were characterized with primary gill lamellae with a central hyaline cartilage. However, three-stage changes were observed after exposure to the three doses of lead nitrate. In stage I, a cartilaginous matrix appeared along with loosening of the epithelial lining of the cartilaginous core and abundant vascular spaces were observed on the secondary gill lamellae. An extra cartilaginous matrix, loosening of the epithelial lining of the cartilaginous core, de-shaped gill lamellae, and degeneration of the secondary gill lamellae were noted in stage II. Lesions in the gill pattern in stage III were represented by shortening of the tips of secondary gill lamellae, damaged gill lamellae, a cartilaginous matrix, and hyperplasia. This indicated that lead exposure resulted in severe histopathological changes in the gills in a dose-dependent manner

Clinical and microbiological aspect of surgical affections associated with current epidemics in bovine

Egypt is endemic with Lumpy Skin Disease (LSD) and Foot and Mouth Disease (FMD), both impose a drastic effect on the economy. These viral diseases are often complicated with secondary bacterial infections; however, scarce data is available. In this study, utilizing microbiological and molecular procedures, we identified a number of secondary bacterial infections complicating FMDand LSD-infected cases. Moreover, the antimicrobial resistance profile of the bacterial isolates was explored. The data showed that several bacterial pathogens including Serratia odorifera, Enterococcus faecium, Paenibacillus apiaries and Microbacterium hominis could be recovered from LSD-infected cases. On the other hand, FMD cases were found to be complicated with Pseudomonas mosselii, Bacillus cereus and Trueperella pyogens. However, Bacillus licheniformis was isolated from both disease conditions. The antimicrobial testing revealed that all pathogens are resistant to more than three antibiotics of different families, indicating the multi-drug resistant capabilities of these isolates. This baseline investigation confirms the presence of many secondary bacterial infections linked to LSD and FMD as well as the widespread antimicrobial resistance among the isolated pathogens, however, the contribution of these pathogens to the mortality rate in both conditions needs further studie

Avaliação da sorção de lindano sobre carvão ativado derivado de palha de arroz e biomassa fúngica de Phanerochaete chrysosporium

Rice straw was used for preparation of activated carbon using chemical activation by impregnation with concentrated H3 PO4 followed by pyrolysis at 500 º C for 2h. Physicochemical properties were investigated by several procedures; elemental analysis, scan electron microscope and porosity characteristics. Batch experimental mode was applied for adsorption and biosorption studies. A matrix effect analysis is applied to correlate the lindane adsorption or biosorption capacity to the agitation time, initial levels of lindane and carbon dose or biosorbent concentration. The Scanning Electron Microscope images equipped with Energy-dispersive X-ray reflect the enhancement of thermo-chemical activation by H3 PO4 in increasing the porosity of AC. Sorption behavior of Lindane by Activated Carbon (AC) and Phanerochaete chrysosporium, respectively have been studied to compare the obtained results in order to consider cost effective method for agriculture wastewater treatment. The adsorption capacity and distribution coefficients were determined for the adsorption system as a function of sorbate concentration. Under the studied concentrations, the adsorption of lindane by AC and its biosorption by Phanerochaete chrysosporium match to Langmuir as well as Freundlich isotherms. Afterword, adsorption and biosorption behavior was assessed by calculation of constants for each isothermal model. Finally, Biosorption of Lindane by Phanerochaete chrysosporium showed higher and faster removal compared with AC derived from rice straw.Utilizou-se palha de arroz para a preparação de carvão ativado por ativação química por impregnação com H3PO4 concentrado seguido de pirólise a 500 ºC por 2h.

Life cycle cost analysis of a sustainable solar water distillation technique

This paper presents a detailed estimation of the fabrication cost, water production cost (WC), and cost payback period (CPP) using annualized life cycle costing for a tubular solar still (TSS). The operation and maintenance cost (OM) and the number of sunny days in a year (d) have a significant effect on the WC. The WC is raised from 3.1 to 4.4¥/L, if the OM increases from 5 to 18% of the capital cost, respectively. The WC is dropped by 35% (in average) when the d increases from 230 to 350 days. In addition, the CPP is greatly affected by the water selling prices and d. The CPP is dropped from 68 to 45 days due to the increase of d from 230 to 350 days (in average), respectively. The fabrication cost of the TSS ($5) and the WC ($31/m3) are affordable and much lower than the single-sloped passive solar still. Finally, it is revealed that the solar radiation is the most influential parameter on the productivity of TSS and a linear proportional relationship is found between them

Effects of Sub-lethal Lead Nitrate and Copper Sulfate Concentrations on Hematological Parameters During Long-term Exposure in Nile tilapia (Oreochromis niloticus)

437-441Nile tilapia (Oreochromis niloticus) weighing 51.66 ± 2.42 g were exposed to 0%, 20%, 40%, and 60% of LC50 to either lead nitrate (Pb(NO3)2) or copper sulfate (CuSO4) for 30 days. The Pb(NO3)2 and CuSO4 concentrations employed in the treatments of this study were 8.8, 17.6, and 26.4 mg/L and 2.57, 5.14, and 7.71 mg/l, respectively, and multiple hematological variables were evaluated. The red blood cell (RBC) count for the control group was 2.41 ± 0.13 while those of the treatment groups exposed to 8.8, 17.6, and 26.4 mg/L of Pb(NO3)2 were 2.21 ± 0.10, 1.94 ± 0.16, and 1.36 ± 0.10 × 106/µl, respectively, at the end of the study. Similarly, the hemoglobin (Hb), hematocrit (Hct), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC), and platelet (PLT( levels significantly decreased as the Pb(NO3)2 concentration increased (p 4, showed decrease in the levels of RBC, Hb, Hct, WBC, and PLT when the concentration of CuSO4 increased, while the MCHC, MCH, and MCV levels significantly increased

Loneliness among women with rheumatoid arthritis:A cross-cultural study in the Netherlands and Egypt

The objective of this study was to explain loneliness as experienced by women with rheumatoid arthritis (RA) in a cross-cultural context. We studied 36 Egyptian female RA patients and 140 female Dutch RA patients.. Self-report data were collected about loneliness, physical and psychological health status, social support and social network, needs for help, attitudes and feelings of guilt. Loneliness was significantly higher among Egyptian (44.2 ± 32.3) than Dutch (12.9 ± 18.9) female RA patients (F = 54.3, p < 0.001). In Egypt, 36% of the variance of loneliness could be explained by worse affect (anxiety and depression; β = 0.51), fewer children (β = 0.31), and higher negative social support for the patients (β = 0.28) in multiple regression analysis. In the Netherlands, 35% of feeling lonely could be explained by worse affect scores (β = 0.52), less positive social support for the patients (β = 0.24), and a higher degree of disability (β = 0.21). Age of the patients and disease duration only explained 4% and 3% of the loneliness of RA patients in Egypt and the Netherlands, respectively. Female Egyptian RA patients experienced more loneliness than Dutch patients. Affect is the most important and constant variable in explaining loneliness in both countries. The role of the family in perceived loneliness is greater in Egypt than the Netherlands. Low social support received by patients is important in explaining loneliness in the Netherlands but not in Egypt
