Pharmacology & Pharmacy 2012年第4期3卷 474-480页

作者： Ausama Ayoob Jaccob Saad abdulrahman Hussain Saad abdulrahman Hussain Department of Pharmacology and Toxicology College of Pharmacy Al-Basra University Basra Iraq Department of Pharmacology and Toxicology College of Pharmacy University of Baghdad Baghdad Iraq.

The risk of pharmacokinetic polyphenols-trace elements interaction may undesirable therapeutic outcomes. We evaluate the long-term use of silibinin, epigallocatechin (ECGC), quercetin and rutin on the absorption and tissue distribution of zinc, copper and iron after single oral doses in rats. Five groups of rats were either with olive oil as control or with one of the polyphenols silibinin, EPGC, quercetin or rutin, administered orally as oily solutions for 30 days. At day 30, a solution contains sulphate salt of zinc, copper and iron was administered orally;3 hrs later blood samples, tissues of brain, kidney and liver were obtained for evaluation of the elements levels. The results showed that the polyphenols increased both serum and tissue levels of these elements compared with controls. This effect was relatively varied according to the structural differences among flavonoids. In conclusion, long-term use of supraphysiological doses of flavonoids increase absorption of Zn, Cu and Fe and their tissue availability in brain, kidney and liver;this effect seems to be different with variations in structural features.

The issue of limited agricultural land and production, rising food demand, and heavy reliance on imported foods in Kuwait have resulted in pressing concerns regarding food security and equity. Currently, Kuwait heavily relies on imports for over 90% of its food supply, which not only impacts the country’s sustainability but also affects other nations. Essential staples like rice, wheat, corn, milk powder, cooking oil, and chicken are particularly vulnerable to recent global price shocks. The consequences of climate change include rising temperatures, warming oceans, increasing incidences of droughts, losses in biodiversity, heightened health risks, and a decline in overall food production. These effects further strain an already stressed ecosystem as Kuwait lacks a comprehensive adaptive strategy that outlines both short-term and long-term action plans/goals to address these challenges. Specifically, within the agricultural, livestock, and fisheries sectors while simultaneously equipping it to handle emergencies or hazardous crises. This paper aims to outline the issues of limited agricultural land and production, rising food demand, and heavy reliance on imported foods, and how Kuwait must prioritize the development and improvement of sustainable agricultural practices and technologies. Furthermore, identifying key stakeholders and their current roles and constraints.

The Effect of the Challawa Industrial Estate on the Physicochemical Properties and Heavy Metal Levels of Portable Water Supply in Kano Metropolis, Nigeria

引用

Journal of Geoscience and Environment Protection 2015年第2期3卷 17-22页

作者： abdulrahman Audu Abdulhakeem Idowu Department of Pure and Industrial Chemistry Bayero University Kano Nigeria

It has been observed that the portable water quality obtained from various locations in Kano Metropolis has shown greater variations in the recent past. Attempts have been made to ascertain the reasons for the variations even though the supplies were from only two treatments plants that obtain their raw water from the same source. A total of 92 water samples comprising of raw (from plants) and treated (from the plants and taps) were collected during rainy and dry seasons between April 2010 and May, 2012 and analyzed using standard analytical techniques. The results of analysis gave the physiochemical properties with range as follows: pH (0.06 ± 6.7 - 6.04 ± 0.02) conductivity (7.23 ±0.04 - 13.33 ± 0.22 S/Cm), turbidity (5.00 ± 0.01 - 449.22 ±1.32 NTU), suspended solids (107.33±3.45 - 712.11 ±5.33 mg/dm3), total dissolved solids (18.50 ± 0.85 -186 .78 ± 2.48 mg/dm3 ), alkalinity (12.53± 0.32 - 80.75 ± 1.23 mg/dm3) and hardness (29.50 ± 1.22 - 58.67 ± 2.34 mg/dm3). The pH values were generally acidic while the turbidity and total solid especially in some locations were higher than the permissible levels set by the World Health Organization for portable water. The concentration of heavy metals (mg/dm3) were found in the following ranges Fe (0.10 ± 0.04 - 0.30 ± 0.02), Cu (0.01 ± 0.001 - 0.03 ± 0.002), Zn (0.13 ± 0.06 - 0.39 ±0.02), Pb (0.03 ± 0.01 - 0.17 ± 0.02), Mn (0.03 ± 0.004 - 0.13 ± 0.003), Cr (0.10 ± 0.04 - 0.31 ± 0.03). The highest values of Fe, Cu and Mn were recorded along the older distribution channel of Challawa. The levels of Pb and Cr were generally high in both routes which are also observed in the raw water used at the two treatments plants. The results obtained from heavy metal concentrations fell within the maximum allowable limit set by the World Health Organization for portable water except in the cases of Pb and Cr. The high Fe, Mn, Cu levels as obtained in the Challawa route were attributed to leaching from rusting in the old galvanized metal pip

Multifaceted role of one-carbon metabolism on immunometabolic control and growth during pregnancy, lactation and the neonatal period in dairy cattle

引用

Journal of Animal Science and Biotechnology 2021年第1期12卷 82-109页

作者： Danielle N.Coleman abdulrahman S.Alharthi Yusheng Liang Matheus Gomes Lopes Vincenzo Lopreiato Mario Vailati-Riboni Juan J.Loor Department of Animal Sciences Division of Nutritional SciencesUniversity of IllinoisUrbanaIL 61801USA .2Department of Animal Production College of Food and Agriculture SciencesKing Saud UniversityRiyadh 11451Saudi Arabia .3Department of Animal Sciences Food and NutritionFaculty of AgricultureFood and Environmental ScienceUniversitàCattolica del Sacro Cuore29122 PiacenzaItaly.

Dairy cattle undergo dramatic metabolic, endocrine, physiologic and immune changes during the peripartal period largely due to combined increases in energy requirements for fetal growth and development, milk production, and decreased dry matter intake. The negative nutrient balance that develops results in body fat mobilization,subsequently leading to triacylglycerol(TAG) accumulation in the liver along with reductions in liver function,immune dysfunction and a state of inflammation and oxidative stress. Mobilization of muscle and gluconeogenesis are also enhanced, while intake of vitamins and minerals is decreased, contributing to metabolic and immune dysfunction and oxidative stress. Enhancing post-ruminal supply of methyl donors is one approach that may improve immunometabolism and production synergistically in peripartal cows. At the cellular level, methyl donors(e.g. methionine, choline, betaine and folic acid) interact through one-carbon metabolism to modulate metabolism,immune responses and epigenetic events. By modulating those pathways, methyl donors may help increase the export of very low-density lipoproteins to reduce liver TAG and contribute to antioxidant synthesis to alleviate oxidative stress. Thus, altering one-carbon metabolism through methyl donor supplementation is a viable option to modulate immunometabolism during the peripartal period. This review explores available data on the regulation of one-carbon metabolism pathways in dairy cows in the context of enzyme regulation, cellular sensors and signaling mechanisms that might respond to increased dietary supply of specific methyl donors. Effects of methyl donors beyond the one-carbon metabolism pathways, including production performance, immune cell function,mechanistic target or rapamycin signaling, and fatty acid oxidation will also be highlighted. Furthermore, the effects of body condition and feeding system(total mixed ration vs. pasture) on one-carbon metabolism pathways are explored. Poten

Design and Analysis of Some Third Order Explicit Almost Runge-Kutta Methods

引用

Applied Mathematics 2016年第1期7卷 13-21页

作者： abdulrahman Ndanusa Khadeejah James Audu Department of Mathematics Federal University of Technology Minna Nigeria

In this paper, we propose two new explicit Almost Runge-Kutta (ARK) methods, ARK3 (a three stage third order method, i.e., s = p = 3) and ARK34 (a four-stage third-order method, i.e., s = 4, p = 3), for the numerical solution of initial value problems (IVPs). The methods are derived through the application of order and stability conditions normally associated with Runge-Kutta methods;the derived methods are further tested for consistency and stability, a necessary requirement for convergence of any numerical scheme;they are shown to satisfy the criteria for both consistency and stability;hence their convergence is guaranteed. Numerical experiments carried out further justified the efficiency of the methods.
