RESUMEN

The aim and objective of this research study was to compare the nutritional status of Severe Acute Malnourished (SAM) Children between Pre and Post admission in Nutrition Rehabilitation Center (NRC). The exploratory as well as descriptive research design was used. The nutritional status was checked by four test variables as Weight-kg, Height-cm, MUAC (Mid-Upper Arm Circumference). The sample size of this study was 211. The normality test was performed using One-Sample Kolmogorov-Smirnov Test. Since the data of four test variable was not normal, hence non-parametric test (Wilcoxon Signed Ranks Test) was used for the comparative study between pre and post condition. The findings concluded that there was a difference of the weight, height, MUAC, of the children in pre and post medical treatment in the NRC for the SAM children.

RESUMEN

Background: Severe acute malnutrition (SAM) may be major obstacle for India to achieve targeted Infant Mortality Rate and under five mortality rate. Malnutrition and infection form vicious cycle and contributes towards mortality. So, malnutrition prevention is major objective of government. Study of malnourished children helps to know aetiology and their response to treatment. The objective of study is to understand clinic-demographic profile of SAM children.Methods: It is retrospective secondary data analysis study. For the purpose of this analysis, we retrieved the data of all children with SAM admitted from 1 January, 2018 to 31 December, 2018 to NRC. At the NRC, a physician conducted a clinical examination in children to detect the presence/absence of medical complications during their admission and these data were available in case sheet.Results: A total of 162 children, aged 6-59 months were referred to the NRC. Around fourty seven percentage of children were in age group 6–12 months Majority of children were in age group of 7 months to one year of age. Majority of children were admitted based on weight of height criteria (Z score < 3SD). Mean admission weight is lower in female compare to male children.Conclusions: Faulty weaning practises and delay in weaning in some cases predisposes later half of infancy period to undernutrition. So, proper health education and good IYCF practices prevent children from undernutrition.

RESUMEN

Aim: The aims of the present study were to purify and characterize L-glutaminase from Penicillium brevicompactum NRC 829; and to evaluate the antitumor activity of the purified enzyme against different tumor human cell lines. Study Design: Testing of antitumor activity of L-glutaminase, purified from a filamentous fungal strain, against four different tumor human cell lines. Place and Duration of Study: Department of Microbial Chemistry, Genetic Engineering and Biotechnology Division, National Research Centre (NRC), Cairo, Egypt, between January 2011 and February 2012. Methodology: P. brevicompactum NRC 829 was grown and maintained on modified Czapek Dox agar (MCD) medium. Cell-free extract was directly used as the source of crude enzyme. L-glutaminase was purified by heat treatment for 20 min at 50ºC, followed by gel filtration on Sephadex G-100 and G-200 columns. Results: An intracellular L-glutaminase from Penicillium brevicompactum NRC 829 was purified to homogeneity (162.75 fold) with an apparent molecular mass (Mr) of 71 kDa. The purified enzyme showed its maximal activity against L-glutamine when incubated at pH 8.5 at 50ºC for 30 min. The purified enzyme retained about 92 % of its initial activity after incubation at 70ºC for 30 min indicating the thermo-stability nature of this enzyme. The highest activity was reported towards its natural substrate, L-glutamine, with an apparent Km value of 1.66 mM. The purified enzyme inhibited the growth of human cell line hepatocellular carcinoma (Hep-G2), with IC50 value of 63.3μg/ml. Conclusion: L-glutaminase purified from Penicillium brevicompactum NRC 829 is a potential candidate in food and pharmaceutical industries.

RESUMEN

An alkaline protease was purified from a halophilic and thermotolerant potent alkaline protease-producing strain Streptomyces pseudogrisiolus NRC-15 using ammonium sulphate precipitation and Sephadex G-100 column chromatography. The enzyme was purified to 77.24-folds with a yield of 91.8% and the specific activity was 112 U/mg of protein. The protease showed a single band on SDS-PAGE with its molecular mass at 20 kDa and exhibited a maximum relative activity of 100% using casein as a substrate and. The enzyme had an optimum pH of 9.5 and displayed optimum activity at 50°C. The enzyme activity was completely inhibited by the serine protease inhibitor PMSF, suggesting the presence of serine residue in the active site. The enzyme activity was increased by the metal ions Ca2+, Co2+, K+ and Mg2+. The enzyme significantly enhanced the removal of stains when used with wheel detergent, indicating the potential of the enzyme for using as a laundry detergent additive to improve the performance of heavy-duty laundry detergent.

RESUMEN

Aim: The aims of this study were to attempt to extract, purify and characterize of Lasparaginase, an antitumor agent, from Penicillium brevicompactum NRC 829. Study Design: Testing of antitumor activity of L-asparaginase against four different tumor human cell lines. Place and Duration of Study: Department of Microbial Chemistry, Genetic Engineering and Biotechnology Division, National Research Centre (NRC), Cairo, Egypt, between June 2010 and November 2011. Methodology: Penicillium brevicompactum NRC 829, a local isolated strain from Culture Collection of the National Research Centre of Egypt, was grown and maintained on modified Czapek Dox medium. The fresh fungal biomass was thoroughly ground with washed cold sand. The cell contents were extracted with cold 0.1M Tris-HCl pH 8.0, thereafter, the slurry obtained was centrifuged at 5500 rpm for 15 min and the supernatant was directly used as the source of enzyme. The purification of L-asparaginase from crudeenzyme extracts of P. brevicompactum was achieved by a sequential multi-steps process starting by heat treatment for 20 min at 50ºC, followed by gel filtration on Sephadex G-100 column, and the most active fractions of L-asparaginase were dialyzed out, lyophilized and then loaded on a Sephadex G-200 column. Results: An intracellular glutaminase-free-L-asparaginase from Penicillium brevicompactum NRC 829 was purified to homogeneity with an apparent molecular mass (Mr) of 94 kDa. The purified enzyme was 151.12 fold with a final specific activity of 574.24 IU/mg protein and about 40% yield recovery. The purified L-asparaginase showed its maximal activity against L-asparagine when incubated at pH 8.0 at 37ºC for 30 min. The enzyme was more stable at alkaline pH than the acidic one and thermally stable up to 60 min at 50-60ºC. L-asparaginase was highly specific for its natural substrate, L-asparagine with a Km value of 1.05 mM. The activity of L-asparaginase is activated by mono cations and various effectors including K+, Na+, 2-mercaptoethanol (2-ME), and reduced glutathione (r-GSH), whereas it is moderately inhibited by various divalent ions including Hg2+, Cu2+, and Ag+. Results indicated the involvement of sulfhydryl group(s) in the enzyme active site(s). The purified enzyme inhibited the growth of human cell line hepatocellular carcinoma (Hep-G2), with IC50 value of 43.3μg/ml. Conclusion: L-asparaginase purified from Penicillium brevicompactum NRC 829 is a potential candidate for medical applications.

RESUMEN

El objetivo del presente estudio fue evaluar el modelo NRC (1996) nivel I para la predicción de la ganancia diaria de peso en novillas suplementadas bajo condiciones tropicales. Para tal fin, se realizaron dos experimentos. En el experimento 1 se evaluaron 30 novillas divididas en dos grupos de 15 animales cada uno, el grupo suplementado (GS) presentó un peso inicial de 365,27 ± 24,40 kg, recibió concentrado a razón de 1% del peso vivo (5,5% PC, 2,85 Mcal ED) y el no suplementado (GNS) con un peso inicial de 367,47 ± 31,65 kg. En el experimento 2 se utilizaron 45 novillas divididas en dos grupos, el GSb con 22 animales, teniendo un peso inicial de 342,23 ± 36,04 kg se les proporcionó alimento a razón del 1% del peso vivo (13% PC; 3,15 Mcal ED) y el GNSb se constituyó por 23 animales teniendo un peso inicial promedio de 326,30 ± 31,53 kg. En ambos experimentos los animales fueron suplementados a lo largo de 45 días, y estuvieron pastoreando praderas de Estrella Africana (Cynodon nlemfuensis), Candelario (Pennisteum purpureum) y Ratana (Ischaemum indicum). En ambos experimentos no se observaron diferencias (P > 0,05) para los cambios de peso. El GS obtuvo ganancias diarias de peso (GDP) de 0,27 kg/d, mientras que el GNS mostró pérdidas de -0,05 kg/d; en el experimento 2 el GSb presentó GDP de 0,90 kg/d y el GNSb de 0,60 kg/d. La GDP predicha en el experimento 1 fue similar a la ganancia observada para el grupo suplementado (P > 0,05) en contraste con la presentada en el grupo no suplementado en el que la ganancia de peso fue sobrestimada (P < 0,05). En el segundo experimento, la predicción de la GDP tanto para el grupo suplementado como el no suplementado fue subestimada (P < 0,05). El nivel 1 del modelo de simulación NRC no fue apropiado para la predicción de los cambios de peso en novillas bajo condiciones tropicales.


The aim of this study was to evaluate the model NRC level 1 to predict the daily weight gain in heifers supplemented under tropical conditions. For this purpose, two experiments were done, in the first experiment 30 heifers were divided into two groups of fifteen animals each, the supplemented group (GS) showed an initial weight of 365.27 ± 24.40 kg, received commercial concentrate to the ratio of 1% of live weight (5.5% PC 2.85 Mcal ED) and the control group which was not supplemented (GNS) with an initial weight of 367.47 ± 31.65 kg. In the second study 45 heifers were divided in two groups, the GSb with 22 animals having an initial weight of 342.23 ± 36.4 kg and given concentrate to the rate of 1% of live weight (13% PC 3.5 Mcal ED) and the GNSb were made up of 23 animals having an initial average weight of 326.0 ± 31.3 kg. In both trials the animals were supplemented throughout for forty-five days and let them grazed on African Star grass (Cynodon nlemfuensis), Candelario grass (Pennisteum purpureum) and Ratana grass (Ischaemum indicum). In both experiments no differences were observed (P > 0.05) in weight change .The GS had daily weight gains (GDP) of 0.27 kg/d while the GNS showed losses of -0.05 kg/d. In the second trial the GSb showed a GDP of 0.90 kg/d and the GNSb of 0.60 kg/d. The predicted GDP of the first experiment was similar in comparison with the observed value for the supplemented group (P > 0.05), in contrast with that presented in the GNS group in which the daily weight gain was over estimated (P < 0.05). In the second trial the GDP predicted for both groups was under estimated (P < 0.05). The level 1 of the NRC simulation model does not seem to be appropriate for predicting changes in weight in heifers under tropical conditions.
