Abstract

The growth of Scenedesmus algae, cultivated in a split-column airlift bioreactor under threedifferent light intensities (94, 187, 468 E /m .s 2  ) and two values of superficial gas velocities (0.3,1 cm/s), was investigated. The physical properties of the culture medium were monitored byvarious analytical methods (optical density, chlorophyll concentration). Samples were taken twice aday (10:00 AM and 5:00 PM) for cell count and optical density measurements. The dynamicgrowth rate of the algae was studied using the integrated three-state fluid dynamics modeldeveloped by Eilers and Peeters (1988). The kinetic parameters for the system under definedlight/dark cycles were evaluated. The obtained results indicate that the growth rate and chlorophyllcontent of the Scenedesmus algae directly proportional to light intensity and superficial gas velocity.

Abstract

Background: Growth hormone is a hormone responsible for the normal body
growth and development by stimulation protein production in muscle cells and
energy release for breakdown of fat. On the other hand leptin is a newly discovered
hormone that is mainly synthesized in adipose tissues it decreases food intake by
causing satiety and promoting energy combustion . Both aging and obesity are
associated with a reduction in growth hormone secretion. In the mean time obese
humans have increased circulating leptin.
Objective: The aim of this paper is to shed light on the contribution of these two
hormones in the mechanism of aging process in an attempt of improving this
process for a better life at old ages.
Subjects and methods: Two hundred and seventy healthy subjects aged 25-64
years old participated in this study. The subjects' were divided into four groups
according to their ages and to three groups according to their weights. Urine
analysis from each subject was carried out to exclude diabetes and renal failure.
Sera from blood samples were used to carry out certain biochemical parameters and
hormone (growth hormone and leptin).
Results: The results obtained show a decrease in the level of growth hormone with
progression of age. In the mean time there is an increase in the level of serum leptin
with the advancement of age. Aging is usually associated with adiposity. Increasing
fat with age is probably multifactorial one potential mechanism for that is reduced
leptin transport across blood-brain barrier..
Conclusion: The increase in leptin level which was observed in elderly age group
and obese group suggest that the associated decrease in growth hormone serum
level is related to obesity in general and in particular to the aging process.

Abstract

Background: Nephrotic syndrome is a chronic disease with frequent relapses and the accumulative dose of steroid play an important role in developing growth retardation.Aims: To detect the degree of growth retardation in long standing nephrotic syndrome and frequent relapsing nephrotic syndrome, and to identify the effect of nephrotic syndrome and steroid therapy on puberty.Patient and methods: A cross sectional study conducted in Child Central Teaching Hospital from the first of January to first of July 2008, on 108 patients with steroid responding nephrotic syndrome, 60 of them were males and 48 were females. All had anthropometric measurement of height and the assessment depend on Tanner growth centile for age and sex, so as the puberty staging according to Tanner staging. The ranges of the patients ages were 2-17y and the mean age was 11.5+4 y. 59.25% (64) were having steroid toxicity; no patient was on cytotoxic drug.Results: The results were shown that 52/ 108 (48.18%) of the patients have got growth retardation (2SD below the mean) Fifty of the patients were at pubertal age, 30 were males and 20 were females. 39 patients had delayed puberty (78%), 36 patients with delayed puberty had steroid toxicity (94.73%). There is a significant relationship between frequency of relapses, duration of illness and steroid toxicity with incidence of delayed puberty and growth retardation.Conclusions: There is a significant correlation between the growth retardation and the development of steroid toxicity. With frequent relapses and long standing nephrosis, there is a chance to develop growth retardation. Delayed puberty is more with steroid toxicity and it is more in males than females.

Abstract

Antimicrobial disk susceptibility tests serve as standard assays for measuring the activity of compounds against pathogenic bacteria. In the current study, some plant-derived proprietary essential oil blends (Olea europaea , Pimpinella anisum L. , Coriandrum sativum , Matricaria chamomilla L. , Borago officinalis , Cimum basilicum L. , Cuminum cyminum , Thymus vulgaris thymol , Menta xpiperita L. , Rosmarinas officinalis comphora) were tested for their antibacterial activity against five common strains of pathogenic bacteria using disk susceptibility tests. A formulation intended for topical use (Essential Oil Formulation 1) (EOF1) inhibited the growth of Escherichia coli, Klebsiella pneumoniae, and Staphylococcus aureus as evidenced by zone inhibition diameter measurements when compared to those reported for standard antibiotics. EOF 1 exhibited no activity against Proteus vulgaris and Staphylococcus epidermidis. The second formulation (Essential Oil Formulation 2) (EOF2), intended for inhalation use, inhibited the growth of all five test bacteria strains with zone inhibition diameters two to three times greater than those reported for standard antibiotics. The growth of all five bacteria strains was inhibited when a cotton swab impregnated with EOF 2 was suspended above the bacterial lawn, indicating a true vapor or fume effect by this formulation.

ان اختبارات الاقراص ضد الجراثيم تعمل كتجارب قياسية لقياس فعالية بعض المركبات ضد البكتريا المرضية. في الدراسة الحالية تم استخلاص الزيوت من بعض النباتات (الزيتون ، اليانسون ، الكزبرة ، بابونك ، الريحان ، كمون ، زعتر البساتين ، نعناع فلفلي و زهرة اكليل الجبل) لاختبار فعاليتهما ضد البكتريا وقد استخدمت خمس انواع من البكتريا المرضية باستخدام أقراص تجارب خصصت لهذا الغرض الطريقة التي تستخدم للاستعمال الموضعي (EOF 1) وهي تستخدم لتثبيط نمو Escherichia coli ، Klebsiella pneumoniae، وStaphylococcus aureus ويستدل على منطقة التثبيط بواسطة قطر منطقة الثبيط حيث تقاس عندما تقارن مع تلك الاقراص المضادات الحيوية القياسية. (EOF 1) توضح بأنه لا يوجد فعالية ضد Staphylococcus epidermidis و Proteus vulgaris . الطريقة الثانية التي استخدمت هي (EOF 2) وهنا تم استخدام الاستنشاق حيث يتم توضيح تثبيط خمسة انواع جميعها من البكتريا بمنطقة تثبيط أقطارها اثنان إلى ثلاثة مرات وهي اكبر من تلك التي تم الاعتماد عليها في أقراص المضادات الحيوية. أن نمو الخمسة أنواع من البكتريا جميعها يتثبط عندما يتم استخدام مسحات القطن التي لحقت بطريقة (EOF 2) وهذا يوضح وجود نمو بكتيري وهذا يشير على وجود بخار أو دخان واضح عند استخدام هذه الطريقة.

Abstract

The pattern of growth and carcass composition of indigenous Iraqi black goats wereassessed through serial slaughter and carcass dissection of 36 kids at six different growthphases. The general linear model procedure and allometric growth ‘equations were used toassess the effects of various factors and differential growth of carcass components, 'respectively. Results showed that kids growth and carcass composition were significantly (P<0-05 to P< O-O01) affected by the growth phase and sex of kids. The effects of growth phaseclearly showed that slower growth of the body and of carcass components were observedduring the third phase (i.e. after weaning). Although there was an effect on fat to lean ratios (P_ < 005), growth phase had no significant effect on dressing out proportion, and lean to boneratios. A significant influence of sex (P < 0-O5) "was observed on lean to bone ratios. Thelog/log regression of weights of dissectible carcass components on hot carcass and emptybody weight showed that the differential growth of bone was declining and that of lean wasisometric relative to the growth of empty body weight. For carcass fat, the allometric growthcoefficients (b) of 1.6 indicated that fat is a late maturing body component. Moreover thegrowth of carcass fat relative to empty body weight in local goat was slower than that reportedfor other goat breeds

Abstract

ABSTRACT: BACKGROUND: Thalassemia is genetic disorder in globin chain production, or it refers to a group of blood disease characterized by decrease synthesis of one of two types of poly peptide chain ( α or ß ) that form a normal adult human hemoglobin molecule ( Hb A- α2 ß2 ) resulting in decrease filling of red cell with hemoglobin and anemia .Growth retardation can occur as a complication of thalassemia as early as the 1st or 2nd year of life but these abnormalities are more prominent after the 6 – 8 years of life . OBJECTIVE: The main objective of the present study was to evaluate the relationship of growth failure and sexual maturity rate (SMR) in children with β-thalassemia major in comparison with controls. MATERIAL AND METHOD : In this case-control study, the growth parameters ( height ,weight ,and sexual maturation ) and S.ferritin of 38 patients aged 8-16 years (24 males 14 females) with β-thalassemia major who were attending thalassemia center in Erbil city Iraqi Kurdistan were compared with those of 38 healthy controls of the same age and gender. RESULTS: Underweight and short stature were found in 23 (61%), 30(79%) of patient group and 3(8%), 3(8%) of control group, the mean age of menarche for female patients was 12.31±2.3 and for control female 11.12±1.31years, The SMR were delayed in 37(97.5%) of patients and in 2 (5.5%) of controls. the level of serum ferritin had no significant relationship with delayed SMR. CONCLUSION: Growth failure (underweight and short stature) and delay SMR significantly occur in thalassemia patients compared to controls, and such growth retardation was more likely to occur after 10 years of duration of the disease

Abstract

This study was carried out in the field of College of Agriculture - University of Salahaddin in Erbil during the season 2009 - 2010 including the evaluation of four hybrids derived from diallel crosses among seven varieties of durum wheat, previously assessed on the basis of combining ability and heterosis of them. The breeding program continued until these hybrids reached the sixth generation, and were compared with three other varieties, two of them cultivated on a large scale. Fifteen traits were studied, including different growth, physiological characters and grain yield and its components. The hybrid (Acsad- 65 × Kosem- N) has been selected to continue its breeding in order to adopt a new variety based on its performance superior in most of the studied traits, especially in the productivity score and grain yield and in traits that are showed positive correlation with the grain yield like leaf area index, net assimilation rate, spike length, 1000-grain weight and spikes/m2, which had the greatest effect in the prediction of grain yield according to the results of multiple regression analysis.

Abstract

background: Human Growth hormone (GH) is 191amino acids protein , gene located on long arm of chromosome 17. its secretion is under control of 2 hypothalamic hormones: growth hormone releasing hormone(GHRH) and somatostatin. Growth hormone is a major promoter of anabolism, its effects on growth are believed to be indirect ,being mediated through peptides called somatomedins or insulin-like growth factors (IGFs) that in turn mediate many of the growth promoting effects of Growth hormone . Recent advances have focused on biological actions of IGFs & their six well defined binding proteins (IGFBPs), the major one is IGF-BP3 which decreased in GH-deficient children. IGFs are GH-dependent serum peptide with potent metabolic & mitogenic activities believed to be responsible for growth effects of GH, they stimulate cellular replication & differentiation . Objective: To evaluate the difference in the response of the children with short stature (of different causes) to a six months treatment with recombinant human GH .Patients And Methods: this is a prospective study in which a total no. of 84 pt (with age ranging from 4-20 years) were included. They were presenting to the endocrine clinic in Al-Mansour teaching hospital for children in 2002 with short stature & growth delay. After the final diagnosis was made, all pt were treated by recombinant GH (in a dose of 0.1-0.2 unit/kg / day) by subcutaneous or intramuscular route at night time (7-8pm) , After completing 6 months of treatment with GH, the patients were evaluated again for height and height velocity, weight, bone age, height age, sexual maturity rate, testicles and phallus in male. Results: There was no significant difference in response to the therapy between male and female ; the mean height velocity in male was 9.37 +/-3.99 cm / year (ranging from 1-19 cm) and the mean height velocity in female was 9.90 +/-4.39 cm / year ranging from 3-20 cm . Conclusion: Growth hormone therapy is effective in increasing the height velocity in most patients with short stature and it should be initiated as early as possible to improve height as much as possible.
