Background: In ovo supplementation of nutrients either amino acids or minerals in broiler chicken has been common more often individually or few nutrients with positive results. In view of the above, in ovo supplementation with combination of amino acids and minerals as a complete nutrient capsule for the gut and immune system development was tested for hatchability since the modern commercial broilers are very fragile to any changes in the internal environment. Methods: Four trials were conducted to study the response of in ovo supplementation of combinations of Lys, Met, Arg, Thr, Glu, Zn, Se and Cu on hatchability of broiler eggs. In trial I, the fertile eggs on day 18 were divided into five groups of 32 eggs in each group. Group I served as control without any amino acids and mineral supplementation. Group II, III, IV and V supplemented with Lys, Met, Arg, Thr, Glu, Zn, Se and Cu @ 2.2, 1, 2.5, 1.6, 2.5 mg, 80, 0.3, 16 µg; 4.4, 2, 5, 3.2, 5 mg, 80, 0.3, 16 µg; 11, 5, 12.5, 8, 12.5 mg, 80, 0.3, 16 µg and 22, 10, 25, 16, 25 mg, 80, 0.3, 18 µg respectively. In trial II, seventy fertile eggs were divided into seven groups, Group I served as control. Group II, III, IV, V, VI and VII were supplemented with graded levels (1x to 6x) of amino acids. The 1x consisted of Lys, Met, Arg, Thr and Glu @ 2.2, 1, 2.5, 1.6 and 2.5 mg, respectively. On day 18, 10 eggs per group were supplemented with graded levels of AA combination into the amniotic fluid. In trail III and IV it was similar to trial II but was without Lys and Met, respectively. Result: Results indicated that hatchability (Trial 1) in Group V, IV, III, II and I were 0, 18, 21.8, 71 and 90.6%, respectively. The Combination of five amino acids (Trial II) (Lys, Met, Thr, Arg, Glu) for in ovo supplementation reduced the hatchability, whereas, combination of four amino acids (Trial III) (Met, Thr, Arg, Glu) without Lys at lower doses resulted in good hatchability (86.6%). In ovo supplementation of amino acid or mineral-amino acid combinations in commercial broiler eggs should be restricted to few amino acids.

Amino Acid Label

To investigate whether recycling of a labeled amino acid would occur after 24 h of infusion, two groups of normal volunteers were infused with [3H]leucine and alpha-[14C]-ketoisocaproate for 4 h and [2H3]leucine for either 4 or 24 h (groups I and II, respectively). Entry of [2H3 )leucine at steady state into the plasma space was indistinguishable from its infusion rate for group I but 30% higher (P less than 0.001) than this rate for group II, demonstrating significant recycling of label. After discontinuation of the infusions, isotope disappearance from the plasma space was followed for 2 h. The 3H and 14C decay data for both groups suggest that plasma leucine and alpha-ketoisocaproate are derived from a single intracellular pool in the postabsorptive state. In group I, the 3H and 2H labels decayed identically; whereas, in group II, the decay of [2H3]-leucine and alpha-[2H3]ketoisocaproate was slower (P less than 0.01) than the decay of [3H]leucine and alpha-[3H]ketoisocaproate, confirming re-entry of label after a 24-h infusion. Therefore kinetic values calculated from models assuming no recycling of labeled amino acids are most likely not quantitative and must be interpreted with care when flux does not change or decreases.

The study was conducted on sows (hybrids of wbp × pbz breeds) and their offspring (until day 75 of life) kept on a farm. The aim of the experiment was to compare the effects of different sources of selenium (Se) on the production performance of the animals, Se content in their blood, the level of Se in sow’s colostrum, as well as Gpx, haptoglobin and immunoglobulin levels in the serum of sows and their offspring. Experimental feed mixtures for pregnant sows (LP), lactating sows (LK) and piglets (prestarter and starter) in each treatment had an identical basic composition, differing only in the type of selenium forms. Group I received a mineral form of Se in an amount of 0.2 mg/kg; group II received a mixture of a Se amino acid chelate and the mineral form of Se (0.1 mg/kg of each); group III received a Se amino acid chelate (0.2 mg/kg), and group IV received Se-enriched yeasts (0.2 mg/kg). Beneficial effects of the organic forms of Se were evident already in the lactation period. Sows, especially those from group II receiving 0.2 mg/kg of organic Se, had a higher feed intake, which was related to a higher milk production during lactation. As a result, on the weaning day, piglets from this group were significantly heavier than the other piglets. After weaning, as well, the piglets in this group were significantly heavier. These results were confirmed by parameters of blood serum and whey colostrum. Selenium as a chelate was more available than the mineral and enriched yeast forms. For this reason, the animals receiving the chelate were healthier (fewer inflammations were noted). The animals in this group also showed a better feed conversion compared with the others. The Gpx level in sows’ serum varied depending on the treatment. The highest level of this parameter was determined in sows from group III (receiving 0.2 mg/kg of organic Se), and it differed significantly from its value in the control group. The results showed that the Gpx level was related to the Se concentration in blood serum, which was also confirmed by a higher production of selenocysteine (a part of Gpx). Cells of the animals from this group were better protected against free radicals. Administration of 0.1 mg/kg of organic Se positively affects the performance of animals, but the recommended level in feed is 0.2 mg/kg of a selenium-containing amino acid....

The effect of environmental conditions on hatching indices of poultry eggs is sufficiently important that new methods for their improvement are sought, among others through exposing the eggs during hatching to an artificially generated magnetic field of variable frequency. Hatching eggs in this study came from Pharaoh quail in the 4th month of laying. The flock was kept under optimum microclimate conditions and fed a complete feed mix containing 21% total protein and 11.7 MJ ME. The eggs (n = 150), after weighing, were divided into 3 groups equal in respect of numbers: control (I) and two experimental (II and III). The eggs of group II and III were exposed to the action of variable magnetic field of the same intensity but different times of application. The highest percentage of dead embryos during incubation in relation to fertilised eggs was found in control group (11.36%), while the smallest was from group II (4.17%). The highest value of hatching indices calculated in relation to fertilised eggs was found in group II (91.6%), while the smallest was in group III (83.7%) with 86.3% in control group. The results point to the possibility of increasing egg hatchability indices through the use of additional variable magnetic field. The chicks hatched from eggs exposed to the action of this experimental agent had similar body weight. The average weight of one-day-old chicks ranged from 7.82 g (group II) to 8.05 g (group III). In the last week of rearing, mean body weight in both sexes was similar and ranged from 168 (group I) to 172 g (group III) in males, and from 186 g (group I) to 199 g (group III) in females; these differences were not statistically significant. The females of group III reached sexual maturity at 41 days, this being one and three days (non-significantly) earlier than birds in group I and II.

Abstract Background Oxidative stress may be one of the causes responsible for mental retardation in phenylketonuria (PKU) patients. Phenylalanine (Phe) reduces antioxidant defense and promotes oxidative stress by causing increase in reactive oxygen-nitrogen species. Our study aimed to investigate the effect of different treatments (amino acid mixture/large neutral amino acid [LNAA] supplements) on oxidative stress which are applied to late-diagnosed patients. To the best of our knowledge, this is the first study to investigate the effect of LNAA supplements on oxidative stress. Methods Twenty late-diagnosed classic PKU patients were included in this study. Patients were classified into two groups: patients under Phe-restricted diet and using Phe-free amino acid mixtures (Group I) (mean age: 13.8 ± 2.8), and patients taking LNAA supplements (Group II) (mean age: 14.8 ± 3.8). Healthy controls (mean age: 13.6 ± 4.8) with ages consistent with the ages of the patients in the experimental groups were included. Results Glutathione peroxidase is lower in patients of taking LNAA supplements than the control group (p = 0.022). Coenzyme Q10 is lower in patients of using Phe-free amino acid mixtures than the control group and it is significantly higher in Group II than Group I (p = 0.0001, p = 0.028, respectively). No significant differences were detected in total antioxidant status, total oxidant status, oxidative stress index, paraoxonase 1 and L-carnitine levels. Conclusions Different treatments affect oxidative stress parameters in PKU patients. In this study, although patients were followed up with classic PKU, patient-specific adjuvant antioxidant therapies should be implemented in response to oxidative stress.

History Of

Aim and Objective:: To determine the mechanisms present in the etiopathogenesis of nasal polyposis. It is not clear whether amino acids contribute in a causal way to the development of the disease. Therefore, the aim of this study was to determine the plasma-free amino acid profile in patients with nasal polyposis and to compare the results with a healthy control group. Materials and Methods:: This was a prospective controlled study that took place in the Otolaryngology Department at the Harran University Faculty of Medicine between April 2017 and April 2018. Plasmafree amino acid profile levels were studied in serum samples taken from a patient group and a healthy control group. Patients who were diagnosed with bilateral diffuse nasal polyposis and were scheduled for surgical interventions were included in this study. Individuals whose age, gender, and body mass index values were compatible with that of the patient group and who did not have any health problems were included in the control group. All the participants whose levels of plasma-free amino acid were thought to be affected by one or more of the following factors were excluded from the study: smoking and alcohol use, allergic rhinitis presence, the presence of acute or chronic sinusitis, a history of endoscopic sinus surgery, unilateral nasal masses, a history of chronic drug use, systemic or topical steroid use in the last three months for any reason, and liver, kidney, hematological, cardiovascular, metabolic, neurological, or psychiatric disorders or malignancies. Results: In patients with nasal polyposis, 3-methyl histidine (3-MHIS: nasal polyposis group (ng) = 3.22 (1.92 – 6.07); control group (cg) = 1.21 (0.77 – 1.68); p = 0.001); arginine (arg: ng = 98.95 (70.81 – 117.75); cg = 75.10 (54.49 – 79.88); p = 0.005); asparagine (asn: ng = 79.84 (57.50 – 101.44); cg = 60.66 (46.39 – 74.62); p = 0.021); citrulline (cit: ng = 51.83 (43.81 – 59.78); cg = 38.33 (27.81 – 53.73); p = 0.038); cystine (cys: ng = 4.29 (2.43 – 6.66); cg = 2.41 (1.51 – 4.16); p = 0.019); glutamic acid (glu: ng = 234.86 (128.75 – 286.66); cg = 152.37 (122.51 – 188.34); p = 0.045); histidine (his: ng = 94.19 (79.34 – 113.99); cg = 74.80 (62.76 – 98.91); p = 0.018); lysine (lys: ng = 297.22 (206.55 – 371.25); cg = 179.50 (151.58 – 238.02); p = 0.001); ornithine (ng = 160.62 (128.36 – 189.32); cg = 115.91 (97.03 – 159.91); p = 0.019); serine (ser: ng = 195.15 (151.58 – 253.07); cg = 83.07 (67.44 – 92.44); p = 0.001); taurine (tau: ng = 74.69 (47.00 – 112.13); cg = 53.14 (33.57 – 67.31); p = 0.006); tryptophan (trp: ng = 52.31 (33.81 – 80.11); cg = 34.44 (25.94 – 43.07); p = 0.005), homocitrulline (ng = 1.75 (1.27 – 2.59); cg = 0.00 (0.00 – 0.53); p = 0.001); norvaline (ng = 6.90 (5.61 – 9.18); cg = 4.93 (3.74 – 7.13); p = 0.021); argininosuccinic acid (ng = 14.33 (10.06 – 25.65); cg = 12.22 (5.77 – 16.87) p = 0.046); and plasma concentrations were significantly higher than in the healthy control group (p <0.05). However, the gamma-aminobutyric acid (gaba: ng = 0.16 (0.10 – 0.24); cg = 0.21 (0.19 – 0.29); p = 0.010) plasma concentration was significantly lower in the nasal polyposis group than in the healthy control group. Conclusion: In this study, plasma levels of 15 free amino acids were significantly higher in the nasal polyposis group than in the healthy control group. A plasma level of 1 free amino acid was found to be significantly lower in the nasal polyposis group compared to the healthy control group. Therefore, it is important to determine the possibility of using the information obtained to prevent the recurrence of the condition and to develop effective treatment strategies. This study may be a milestone for studies of this subject. However, this study needs to be confirmed by further studies conducted in a larger series.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Purpose. To compare the parameters of a light sensitivity (LS) of the central zone of a retina after vitrectomy due to reghmatogenous retinal detachment (RRD) with a silicone oil tamponade (SOT) and gas tamponade (GT). Material and methods. The study included 20 eyes after pars plana vitrectomy due to macula-off rhegmatogenous retinal detachment (RRD) by 25G. All patients were divided in 2 groups depending on the choice of the tamponade. The group I (10 eyes) included cases with the silicone oil tamponade (SOT) (1300 cSt), in the group II (10 eyes) – the gas tamponade (GT) (C2F6). The control group included contralateral eyes without ophthalmic pathology. All patients underwent standard ophthalmological examination and fundus- microperimetry (FMP) on the 30th day after removal of the SOT for the group I, or on the 30th day after the C2F6 tamponade for the group II. Results. According to FMP data, the parameter of average light sensitivity (LS) in the group I was significantly reduced, both in comparison with the group II (p=0.007) and the control group (p=0.003). Differentiation by zones in the group I revealed a decrease in each analyzed parameter in comparison with the control group (p<0.05) and a decrease in the 2nd zone (p=0.031) and the 4th zone (p=0.038) in comparison with the group II. In the 1st zone of the group I the formation of a relative scotoma was revealed in 4 cases out of 10 (40%). The parameters of light sensitivity (LS) in comparison with the control in the group II were significantly reduced when analyzed in each zone (p<0.05). A strong positive correlation was found between the Best Corrected Visual Acuity (BCVA) and the average LS in the group II (r=0.87). Conclusion. There is a decrease in the functional parameters of the retina with SOT compared with GT in the form of a decrease in the LS parameter in the 10° zone according to FMP data. Key words: retinal detachment, photosensitivity, microperimetry, silicone tamponade.

Aim: To Compare frequency of sore throat in early post operative period among patients undergoing general anaesthesia and endotracheal intubation for abdominal surgeries who are given dexamethasone and normal saline. Study Design: Randomized controlled study Setting: Department of Anesthesia/ ICU, Sheikh Zayed Hospital, Lahore Duration of study: Six months i.e. 25-09-2009 to 25-03-2010. Methodology: 120 patients undergoing elective general surgery on abdomen were selected. They were divided into two groups. Group I received dexamethasone 8mg (2ml) I/V pre-operatively and group II received 2ml normal saline I/V pre-operatively. Chi square test was used. Visual analogue (VAS) scale was used for recording sore throat. The VAS score ≤4 was considered as no sore throat and VAS scores>4 were considered as the sore throat. Results: Frequency of post-operative sore throat after the first 24 hours following GA and endotracheal intubation was lower in group (I) as compared to the control group (II). Eleven (20%) patients with dexamethasone had post-operative sore throat compared to thirty one (56.3%) patients in control group. (p<0.01). Conclusion: Pre-operative use of dexamethasone was associated with decreased incidence of post-operative sore throat.

The experiment was carried out to clarify the roles of insulin and amino acids on protein synthesis in fed lactating goats (30 days postpartum). Protein synthesis in the liver and various skeletal muscles was assessed after an intravenous injection of a large dose of unlabeled valine containing a tracer dose of L-[2,3,4-3H]valine. The animals were divided into three groups. Group I was infused with insulin (1.7 mumol/min) for 2.5 h under glucose, potassium, and amino acid replacement. Group A was infused with an amino acid mixture to create stable hyperaminoacidemia for 2.5 h. Group C animals were controls. The fractional synthesis rates (FSR) were 31.5 +/- 2.2, 6.5 +/- 0.4, 4.3 +/- 0.8, 4.0 +/- 1.2, 3.9 +/- 1.2, and 3.6 +/- 0.4%/day (SD) in liver, masseter, diaphragm, anconeus, semitendinosus, and longissimus dorsi, respectively, for group C. Neither hyperinsulinemia in group I nor hyperaminoacidemia in group A had not affected by hyperinsulinemia but was stimulated by hyperaminoacidemia (+30%, P < 0.05). In contrast to previous experiments in which a labeled amino acid was constantly infused, this study revealed a stimulating effect of amino acids on protein synthesis in the liver but not in skeletal muscles. As previously observed in studies with the constant-infusion method, insulin had no effect on protein synthesis.
