Analysis of amino acid in albumen and circular RNAs in ovaries of laying hens by chromatographic analysis and RNA-seq

Abstract In this study, the amino acid analyzer was used to analyze the hydrolyzed content of albumen, and free amino acid in albumen were analyzed by HPLC, besides, circRNAs in ovaries of laying hens during different developmental stages were identified using RNA seq. No significant differences were observed in the amino acid content of albumen at varied developmental stages. Additionally, we explored the potential of microwave digestion, which was shown to be an effective technique for sample pretreatment to analyze the amino acid content of albumen; the optimized reaction conditions were microwave power of 600 W, and temperature of 180 °C for 20 min. A total of 10,355 circRNAs were identified by RNA-seq screening, and 61 differentially expressed circRNAs were initially identified. Our research suggested that HPLC is a better method to analysis the free amino acids in albumen, furthermore, provides important information about the quality of eggs of laying hens at different developmental stages and thereby may be applied in poultry molecular breeding techniques.

INFLUENCE OF ALFALFA SEED OIL SUPPLEMENTATION LEVELS ON GROWTH PERFORMANCE, BLOOD METABOLITES AND MUSCLE FATTY ACIDS IN BROILERS.

he objective of the present study was to investigate the effect of alfalfa seed oil (ASO) supplementation levels on growth performance, some blood metabolites and muscle fatty acids profile in broilers. A total of 600 one-day-old, unsexed Cobb broilers chicks were divided into four equal experimental groups (150 birds), each included three replicates of 50 chicks. The first treatment was control without any additives in feed; however, from second to forth group were supplemented with 250, 500, 100 g/ ton feed of ASO. Body weight, body weight gain and mortality rate were not influenced by alfalfa seed oil supplementation. On the other hand, feed intake was significantly (P=0.05) decreased and thus, feed conversion ratio (FCR) was improved significantly (P=0.03). Supplementation of ASO in broiler diet did not affected the carcass, heart, liver, gizzard and breast and thigh muscle relative weights, while abdominal fat relative weight was decreased significant (P=0.03) by added 1000 g ASO /ton feed. Plasma total protein, albumin, globulin, glucose and the activity of glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were not affected by alfalfa seed oil supplementation levels, while plasma total cholesterol was significantly (p=0.002) decreased. Furthermore, the muscle contents of palmitic, oleic acid and liver MDA were not statistically (P> 0.05) affected by dietary alfalfa seed oil. However, the muscle contents of linolenic acid and vitamin E were significantly increased by increasing ASO supplementation level from 250 to 1000 g /ton feed, compared to the control group. Therefore, it could be concluded that alfalfa seed oil supplementation to broiler diets improved growth performance, modified plasma cholesterols and muscle fatty acids profile in broilers.

Effect of Induced Hyperthyroidism on Pancreas of Adult Female Albino Rats

Introduction: A condition known as hyperthyroidism can lead to a wide range of health issues, including osteoporosis, oxidative liver damage, diabetes mellitus, as well as cardiovascular disease. Objective: To examine the detrimental effects of hyperthyroidism on the pancreatic structure of adult female albino rats. Materials and Methods: twenty-one adult virgin female albino rats were assigned to 2 groups; control and induction of hyperthyroidism. Serological analysis to assess thyroid functions, oxidative stress and lipid peroxidation analysis was carried out. Pancreatic samples were processed for light microscopic examination. Results: Hyperthyroidism caused both biochemical and histological changes on pancreas of adult female albino rats. The biochemical changes in the form of significant decreased in the thyroid stimulating hormone serum level, significant reduction in level of serum superoxide dismutase and the malondialdehyde level was significantly increased in the hyperthyroid rats. The histological changes were loss of its general architecture. The pancreatic acini appeared irregular, vacuolated and had dark nuclei. Some islets of Langerhans appeared shrunken and the acini did not have the normal smooth demarcation from the surface. Conclusion: Hyperthyroidism seriously affected the histological structure of the pancreas with subsequent disturbance in the biochemical markers.
Effects of drying methods and acidic strength on physicochemical properties of potassium caseinate

The aims of the present study were to characterize physicochemical characteristics and chemical structures by Fourier Transform Infrared (FTIR), and mark dissolved protein content, microstructure, and moisture content of potassium caseinate prepared by drying methods and acid strength. The experiment was arranged according to factorial complete randomized design with triplicates, while data from FTIR and microstructure analysis was presented descriptively. The results demonstrated that acids and drying methods for preparing potassium caseinate could increase antioxidant activity, a* score (reddish) and b* score (yellowish). Specifically, freeze-drying method coupled with acid treatments accounted for reducing moisture content but improved viscosity and microstructural properties. Briefly, we could argue that drying techniques and acids established noticeable effects on the quality of potassium caseinate.
LC-ESI-MS/MS analysis, toxicity and anti-anaemic activity of Rubia tinctorum L. aqueous extract

The present study investigated the chemical profile, toxicity, and anti-anaemic activity of Rubia tinctorum root aqueous extract against phenylhydrazine induced hemolytic anaemia. Phenolic compounds were analyzed by LC-ESI-MS/MS; acute toxicity test was evaluated by administering a single dose of 2,000 mg.kg-1 of the extract; anaemia was induced by administration of 40 mg phenylhydrazine by intraperitoneal injection for 2 days. Moreover, the anti-anaemic activity was evaluated by measuring the haematological parameters of rats treated with iron and aqueous extract for 15 days. The LC-ESI-MS/MS analysis results revealed the presence of 31 phytochemical compounds, among them, citric acid was found as the most abundant. No signs of toxicity or death were recorded, indicating that the LD50 of R. tinctorum root extract is higher than 2,000 mg.kg-1. Furthermore, the aqueous extract increased red blood cell levels by 69.82 and 71.67 % in the groups treated with 200 and 400 mg.kg-1 of the extract, respectively. Besides, a significant increase in hemoglobin from 12.05 ± 0.15 to 12.9 ± 0.52 g.dL-1 was noted in rats treated with 400 mg.kg-1 of extract. Thus, the data indicate that the root extract could be considered a natural source for the treatment of anaemia.
MODERN INSTRUMENTAL METHODS FOR QUALITATIVE AND QUANTITATIVE ANALYSIS OF LAPATINIB IN BIOLOGICAL FLUIDS AND DOSAGE FORMS (REVIEW)

Lapatinib is a small molecule, a heterocyclic quinazoline derivative. The drug is used for targeted therapy of patients with breast cancer, in which there is overexpression of the human epidermal growth factor receptors (HER/ErbB). This review is devoted to studying modern instrumental methods of qualitative and quantitative analysis of lapatinib, which can be used both for quality control and standardization (of bulk pharmaceuticals and dosage forms) and pharmacokinetics studies of a drug. Reverse-phase high-performance liquid chromatography (RP-HPLC) is mainly used to identify lapatinib in tablets. Depending on the purpose of the study, various detectors are used (ultraviolet or diode-matrix detector), which makes it possible to determine not only the native compound but also the products of its degradation. Definition of lapatinib in the presence of degraded products is necessary for forced degradation studies to determine drug stability. When a drug is being developed, it is important to define and understand its pharmacokinetics. For such studies, high-performance liquid chromatography (HPLC) coupled with the mass selective detector is often used. It allows determining lapatinib in biological fluids. However, these methods are not applicable for identifying the drug directly in dosage forms and require further development and validation.

EFFECT OF DIFFERENT ENERGY LEVELS WITH OR WITHOUT XYLANASE ENZYME ON PRODUCTIVE PERFORMANCE AND PHYSIOLOGICAL STATUS OF BROILER CHICKS

n experiment was conducted to investigate the effect of xylanase supplemented diet by its role to remove antinutritive effect of non-starch polysaccharide (NSP) is well established and optimizing the ME utilization. A total of 315, one-day-old unsexed Cobb broiler chicks, were randomly assigned into seven experimental groups of 3 replicates each with 15 birds in each replicate. The chicks were offered corn–soybean meal basal mash diets that was prepared to contain 3000 kcal ME/kg and 23% crud protein during starter period till 21 days of age, followed by 3100 kcal ME/kg and 21% crud protein during grower period till 35 days of age, and 3200 kcal ME/kg and 19% crud protein during grower period till 42 days of age. One of the seven experimental groups was fed this diet as such to serve as control while, the remaining six groups were fed the lowered ME levels by 150 or 300 kcal compared basal diet and supplemented with 0,100 and 200 mg xylanase/kg diet during starter, grower, and finisher periods, respectively. The obtained results revealed that the highest (P<0.05) body weight and weight gain recorded of birds fed dietary T3 compared to control group. Birds fed dietary T3 and control group consumed approximately similar amounts of feed and recorded a significantly better feed conversion ratio (FCR) than the control. Relative carcass weight yielded of broilers fed dietary treatment and control basal diet were statically (P< 0.05) similar, expect those fed dietary T4 recorded a significant lower value of carcass yield compared with either control or other treatment groups. Total edible parts were significantly heavier of birds fed xylanase-supplemented diets (T3, and T6) compared with that of the control and other groups. Birds fed dietary T3 recorded the highest (P< 0.05) value of relative thymus and spleen weight compared others. While, insignificant differences were observed of bursa among other treatments. The hematological parameters (Hb, PCV, RBCs and WBCs) were significantly (p≤ 0.01) improved of birds fed dietary T3 compared with counterparty of control. Total protein, albumin and globulin were significantly increased while, the concentration of triglycerides and cholesterol were significantly decreased of birds fed dietary T3 and T2 compared with the control group.
Creating and Sustaining High-Quality Senior Capstone Experiences

The 2011 Outcomes Assessment Model for accreditation by the Association of Technology, Management, and Applied Engineering (ATMAE) requires coursework in both management and technical areas of technology, with a “reasonable balance” between the practical application of “how” and more conceptual application of “why” (ATMAE Outcomes Assessment Model, 2013). One way to meet this requirement is with a senior capstone course. Capstone courses focus on the integration and application of technical skills and knowledge along with consideration of multiple realistic constraints. A high quality capstone experience has many positive outcomes for the student, faculty, and department. However, capstone courses can be challenging for both students and faculty.

Efficiency of Humic Acid and Three Commercial Biocides Against Meloidogyne incognita and Tylenchulus semipenetrans Associated with Olive Plants

In comparison to a chemical nematicide (Oxamyl), humic acid and three commercial bioagents namely Abamectin (Streptomyces avermitilis), Clean Root (Bacillus subtilis) and Nemastrol (chitinase, glycosynolates, Glucanase, cytokinins and flavonoids) were tested in a greenhouse and field to see how they affect the population density of root-knot and citrus nematodes and, as a result, the effects on plant growth parameters. In greenhouse test, humic acid gave the highest results in terms of increasing total plant fresh weight (403.8 %) and shoot dry weight (400%) compared to untreated plants. Regardless chemical nematicide used, Abamectin showed the best results in suppressing Meloidogyne incognita reproduction with a reduction percentage of (85.4%), while Nemastrol resulted the best reduction percentage of Tylenchulus semipenetrans population (84.4%). Six months after treatment, Nemastrol showed the highest decrease percentage of root-knot nematode (82.4%) and citrus nematode (75.6%) in a field experiment. On the other hand, Oxamyl and humic acid outperformed other treatments in terms of improving the percentage of fruit weight (166.84 and 145.87 %), respectively. Furthermore, all treatments had an impact on the fatty acid composition of olive oil. At the same time, compared to untreated trees, such treatments resulted in lower peroxidase and polyphenoloxidase activities. In terms of phenol content, it was clear that Nemastrol, followed by humic acid improved total phenol content. However, Clean Root gained the highest overall protein concentration. Furthermore, humic acid increased the total carbohydrate level.
Noise Scaling and Community Noise Metrics for the Hybrid Wing Body Aircraft

An aircraft system noise assessment was performed for the hybrid wing body aircraft concept, known as the N2A-EXTE. This assessment is a result of an effort by NASA to explore a realistic HWB design that has the potential to substantially reduce noise and fuel burn. Under contract to NASA, Boeing designed the aircraft using practical aircraft design princip0les with incorporation of noise technologies projected to be available in the 2020 timeframe. NASA tested 5.8% scale-mode of the design in the NASA Langley 14- by 22-Foot Subsonic Tunnel to provide source noise directivity and installation effects for aircraft engine and airframe configurations. Analysis permitted direct scaling of the model-scale jet, airframe, and engine shielding effect measurements to full-scale. Use of these in combination with ANOPP predictions enabled computations of the cumulative (CUM) noise margins relative to FAA Stage 4 limits. The CUM margins were computed for a baseline N2A-EXTE configuration and for configurations with added noise reduction strategies. The strategies include reduced approach speed, over-the-rotor line and soft-vane fan technologies, vertical tail placement and orientation, and modified landing gear designs with fairings. Combining the inherent HWB engine shielding by the airframe with added noise technologies, the cumulative noise was assessed at 38.7 dB below FAA Stage 4 certification level, just 3.3 dB short of the NASA N+2 goal of 42 dB. This new result shows that the NASA N+2 goal is approachable and that significant reduction in overall aircraft noise is possible through configurations with noise reduction technologies and operational changes.
A Light at the End of the Tunnel: How the Right Workplace Structure Can Help Disrupt the Negative Impact of Abusive Supervision

ABSTRACT Abusive supervision is costly for organizations because it promotes employee deviance. In this paper, we argue that workplace structure plays a critical role in determining the strength of the relationship between abuse and interpersonal deviance on part of victims. However, theory offers contrasting views of this effect. One view suggests that formalized structures provide clear direction and strict guidance on subordinates’ work behaviors, thereby mitigating deviant reactions to abusive supervision. In contrast, a second perspective postulates that formalized structures further burden employees, thereby heightening aggressive reactions to abuse. Results from Study 1 support the mitigating effect of structure. Study 2 replicates and extends these findings by showing that role ambiguity is the underlying psychological mechanism through which formalization lessens employee deviant responses to abuse.
The Impact of Geometric Imperfections on Metallic Stiffened Panels with Skin Bay Buckling Containment Features

The impact of geometric imperfections on the stability of conventional metallic stiffened panels is well developed. For novel panel configurations which incorporate skin buckling containment features equivalent knowledge is unavailable. The objective of this paper is thus to develop an initial understanding of the impact of geometric imperfections on panel design which employ skin bay prismatic buckling containment features. To achieve this compression test data for a conventional and a novel panel design is used to validate nonlinear buckling and collapse Finite Element simulations. The validated simulations are then used to examine the impact of geometric imperfections on static strength performance, and to benchmark the sensitivity of novel panel design against conventional panel design.
