Published: October 2019

The wide utilize of antibiotics has led to spreading of antibiotics resistance among bacterial populations and reducing the effectiveness of antibiotics. However, most of the administrated antibiotics enter the environmental matrixes through direct runoff and excretion of feces or urine as unchanged original drugs, active metabolites and/or degradation products. Amoxicillin is one of the most valuable and highly consumed antibiotics. Thus, amoxicillin removal from pharmaceutical wastes offers many economic and environmental benefits. Therefore, the aim of current study was to characterize an identification method for amoxicillin and to study the effects of different parameter such as order of addition, nature of the complex, temperature and effect of concentration and type of the base. A spectrophotometric, selective and sensitive method has been proposed for the determination of Amoxicillin. The method is based on the oxidation of potassium ferricyanide and coupling of the oxidized product with the reagent, 4- aminoantipyrine, to give intensely colored complex that absorbs light strongly in the spectral region of 509nm at room temperature. The results found that the order of addition, drug (Amoxicillin)- potassium ferricyanide –base-4- aminoantipyrine, gave highest absorbance and sensitivity, the best base was NaOH (0.1N) needful for developing the colored product and increase its stability. That complex, at 25°C, gave a preferable sensitivity and was selected for further use in this study. Under the proposed optimum conditions, Beer’s law was conform in the concentration range of ( 5-100 mg L−1). Good linearity (r2=0.9994). Calculation of standard error, limit of detection (LOD) (signal/noise = 3), accuracy and precision (RSD%) better than 1%. The utilized method seemed simple, rapid, reproducible and accurate. In addition, it is applicable for the assay of the drug under investigation in various dosage forms and the results are in very good concord with those obtained in previous studies.

Published: October 2019

CD38 may play important roles in the pathophysiology of different human diseases, like obesity, diabetes, chronic lymphocyte leukemia and other disease either through the enzymatic or receptorial functions. Also, it has a role in energy homeostasis, signal transduction, and aging. Interestingly, CD38 is a major regulator of intracellular nicotinamide adinin dinucleotide (NAD+) levels. It is the main NADase enzyme, it uses NAD to produce the main calcium mobilizing messengers. On the other hand, NAD is a key molecule that is involved in multiple signaling pathways and metabolic conditions. Thus, it is of highly importance to regulate of CD38 catalytic activity. Therefore, it is of interest to many investigators to find inhibitors of CD38 function to verify CD38 as a new potential therapeutic target. Here we draw attention to the importance of CD38 catalytic function and its involvement in several disease. In addition to the importance of intracellular NAD, the main NAD-consuming enzymes, and biosynthesis enzymes. The main regulators of CD38 activity (inhibitors or activators) are also reported to provide a theoretical basis for further drug design.This review is aimed at giving a brief insight into the progress made to date about CD38/NAD relationship. CD38/NAD link plays important roles in signaling pathways that may contribute to human pathologies, it is a potential target for drug development.

Acute lymphoblastic leukemia (ALL) constitutes a family of genetically heterogeneous lymphoid neoplasms derived from B- and T-lymphoid progenitors. The aim of the study was to assess the oxidative status through measurement of antioxidants levels in patients with ALL and deduce any differences in their concentrations from normal values. The study was included 60 children with acute lymphoid leukemia diagnosed by blood film and bone marrow examination and 30 healthy subjects taken as healthy for the initial laboratory tests. Oxidative stress, blood antioxidants status, and liver enzymes profiles were measured in all groups. Our results showed that Antioxidants levels and Hb were significant decreased (P⩽0.05) in ALL patients. In contrast MDA, liver enzymes, leukocytes and Lymphocytes count were significant increase (P⩽0.05) in ALL patients compared to healthy control subjects. Boys predominance was evident, the fraction of patients living in urban areas was more than those of rural regions. Also, the results from statistical analysis revealed that there was a strong correlation between ABO blood groups and leukemia. The present study concludes that free radicals have been concerned in the pathogenesis of leukemia in childhood, the mechanism of increased MDA is that may be due to lymphocyte cells are source superoxide and other oxygen metabolites which lead to lipid peroxidation.

This experiment was conducted determine the effect of dates molasses, ascorbic acid and feeding method on growth performance and carcass characteristics in broiler chickens. A total of 480 one day–old broilers Ross 308 were randomly allotted to 8 experimental groups in a complete randomized design. Basic treatments were divided initially at time of hatching, a- early feeding group which had a free access to water and diet from direct time of post hatching until 6 weeks, this group contained 240 chicks which distributed into 4 subgroups with 4 replicates/subgroups. The 1st subgroup was fed basal diet (control), the 2nd subgroup was fed basal diet plus 1000 ml of dates molasses/l of drinking water. The 3rd subgroup was fed basal diet plus 50 g of L-ascorbic acid/l of drinking water. The 4th subgroup was fed basal diet plus 1000 ml and 50 g of dates molasses and L-ascorbic acid, respectively / l of drinking water, b- late feeding group which had free access to water and diet after 12 hours from their reaching to farm until 6 weeks, this group was also contained 240 chicks which distributed into 4 subgroups and 4 replicates/subgroup with the same feed additives mentioned earlier.All the chickens were reared in the same environmental and management conditions. Growth performance (body weight, weight gain, feed intake, water consumption and feed conversion ratio) were determined on 3 and 6 weeks. Carcass traits (dressing percentage, breast, Thigh and femoral part, abdominal fat), factor of productive efficiency and mortality were assessed on 6 weeks. Growth performance was significantly (P<0.05) improved in the dates molasses and ascorbic acid in both early and late feeding treated broilers compared to the not supplemented control. Dates molasses in water increased the relative weight of dressing percentage, breast and abdominal fat as well as ascorbic acid increased the relative weight of thigh and femoral part. These data suggest that the dates molasses and ascorbic acid may improve growth performance in broiler chickens.

Authors: Golovin P A , Rul N I , Bagraev N T , Klyachkin L E , Malyarenko A M
Published: October 2019

The experimental data of the optical and electric features of the silicon nanosandwiches obtained by silicon planar technology in the frameworks of the Hall geometry are presented. Silicon nanosandwiches represent the ultra-shallow silicon quantum wells of 2nm wide that are confined by δ-barriers heavily doped with boron, which appear to be used as the phase invertors and modulators of optical THz spectra and electric signals. The negative-U dipole boron centers formation, which appear to confine the edge channels, results in the effective mass dropping and corresponding reduction of the electron-electron interaction thereby giving rise to the macroscopic quantum phenomena at high temperatures up to room temperature. The modulation phase shift of the THz electroluminescence spectrum and phase control of the longitudinal conductance are observed by changing either the magnitude of the source-drain current or the voltage applied to the external gates of the silicon nanosandwiches within the quantum Faraday effect.

Published: October 2019

Calibration of measurement systems using well-prepared calibration materials is an important means of making traceability in chemical measurements. Traceability is established through the use of measurement standards (such as certified reference materials) that are appropriate for each parameter. Pure substance certified reference materials such as elemental standard solutions are the most commonly used for calibration, called external calibrations using one, two or multiple standards. In this study, one-point calibration method has been applied for characterizing of Fe, Ni and Pb standard solutions. The results show that the concentration of the Fe, Ni and Pb standard solutions with their relative uncertainties were found to be 997.81 ± 6.34 mg/kg, 997.61 ± 8.10 mg/kg, 1004.29 ± 8.62 mg/kg, respectively.

In this research, sol-gel process was applied to synthesize zeolite-A from rice husk silica and aluminum metal. For preparation of the zeolite, the specified amount of rice husk silica and aluminum metal was separately dissolved in NaOH solution, and both solutions were transfered in to a laboratory mixture for complete mixing and production of gel. The gel was converted into solid zeolite precursor by oven drying of the gel for 24 hours. The precursor was transformed into zeolite by subjecting to different calcination temperatures, and then characterized using different techniques. The zeolites were also tested as catalyst for transesterification of Ricinius communis oil. Development of structure of the zeolite was confirmed using FTIR and XRD techniques analyses, while SEM analysis revealed the characteristic of the samples as porous and multiphasic materials. The zeolites were found to exhibit good catalytic activity as revealed by the results of transesterification of Ricinius communis oil. Appreciable catalytic activities were also demonstrated by the reaction yields achieved which are in the range of 68 to 82%.
