Effects of Moringa (Moringa oleifera Lam.) Leaf Meal on Performance, Carcass, Organs, Eggs and Meat of Japanese Quails

There are several reports on the utilisation of Moringa oleifera in poultry diets due to its essential bioactive compounds yet,little is known about its influence on Japanese quail eggs and meat qualities. Hence, the need to examine performance, eggs and meat qualities of Japanese quail hens fed M.oleifera leaf. To achieve this, 240 Japanese quail chicks were allocated to three dietary treatments: D1: control, 0.0% (without M. oleifera leaf meal),D2: (0.5% M. oleifera leaf meal) and D3: (1% M.oleifera leaf meal). Data on performance, carcass, organs, eggs and meat qualities were collected and subjected to ANOVA at 0.05. Results revealed that feed consumption was lowest (2,701g) in D1 and highest (2,800g) in D2, carcass weight varied from 100 - 100.67g, thigh weight (12.66 - 13.58g) and breast weight was highest (40.41g) in D3. Liver weight was lowest (3.25g) in D1, kidney was largest (0.91g) in D3 whereas, the heart, gizzard and spleen weights ranged from 1.00 - 1.16g, 3.08 - 3.50g and 0.04 - 0.08g, respectively. In the eggs, crude protein (10.94%), crude fat (6.71%), ash (1.36%), high-density lipoprotein (96.12mg/100g) and low-density lipoprotein (120.67mg/100g) were highest in D1. Total cholesterol (364.08mg/100g) and triglycerides (147.27mg/100g) were least in D1 and the caloric value varied from 1.46 -1.47kcal/g. In the meat, crude protein (17.14%) and energy value (1.96kcal/g) were best in D2 but, crude fat (12.62%), ash (2.85%) and carbohydrates(1.31%) were superior in D3. In both eggs and meat, no crude fibre (0.0%) was detected. In any case, all the parameter values were within the normal ranges given in healthy Japanese quails at similar age. Consequently,addition of M. oleifera leaf meal at 1.0% to Japanese quail diets might not depress performance, affect carcass quality, cause organs dysfunctions but may improve nutritional quality of the eggs and meat

A Rydberg Quantum Simulator

Following Feynman and as elaborated on by Lloyd, a universal quantum simulator (QS) is a controlled quantum device which reproduces the dynamics of any other many particle quantum system with short range interactions. This dynamics can refer to both coherent Hamiltonian and dissipative open system evolution. We investigate how laser excited Rydberg atoms in large spacing optical or magnetic lattices can provide an efficient implementation of a universal QS for spin models involving (high order) n-body interactions. This includes the simulation of Hamiltonians of exotic spin models involving n-particle constraints such as the Kitaev toric code, color code, and lattice gauge theories with spin liquid phases. In addition, it provides the ingredients for dissipative preparation of entangled states based on engineering n-particle reservoir couplings. The key basic building blocks of our architecture are efficient and high-fidelity n-qubit entangling gates via auxiliary Rydberg atoms, including a possible dissipative time step via optical pumping. This allows to mimic the time evolution of the system by a sequence of fast, parallel and high-fidelity n-particle coherent and dissipative Rydberg gates.Comment: 8 pages, 4 figure

Reversal of isolated unilateral optic nerve edema with concomitant visual impairment following blunt trauma: a case report

<p>Abstract</p> <p>Introduction</p> <p>Serious injury to the optic nerve is an uncommon entity but may result in permanent visual disability. Isolated trauma of the optic nerve is usually associated with blunt skull trauma involving fractures of both skull and optic canal, but may also occur from blunt ocular trauma.</p> <p>Case presentation</p> <p>We report a woman who developed isolated unilateral optic nerve edema with corresponding visual deficits after a rear-end collision accident. She was treated with corticosteroids and had a favourable outcome.</p> <p>Conclusion</p> <p>The approach described here was successful in this case but the current body of evidence still lacks a validated approach to the management of traumatic optic neuropathy and each case needs to be individually assessed.</p

Three-Dimensional, Tomographic Super-Resolution Fluorescence Imaging of Serially Sectioned Thick Samples

Three-dimensional fluorescence imaging of thick tissue samples with near-molecular resolution remains a fundamental challenge in the life sciences. To tackle this, we developed tomoSTORM, an approach combining single-molecule localization-based super-resolution microscopy with array tomography of structurally intact brain tissue. Consecutive sections organized in a ribbon were serially imaged with a lateral resolution of 28 nm and an axial resolution of 40 nm in tissue volumes of up to 50 µm×50 µm×2.5 µm. Using targeted expression of membrane bound (m)GFP and immunohistochemistry at the calyx of Held, a model synapse for central glutamatergic neurotransmission, we delineated the course of the membrane and fine-structure of mitochondria. This method allows multiplexed super-resolution imaging in large tissue volumes with a resolution three orders of magnitude better than confocal microscopy

Positive psychology of Malaysian students: impacts of engagement, motivation, self-compassion and wellbeing on mental health

Malaysia plays a key role in education of the Asia Pacific, expanding its scholarly output rapidly. However, mental health of Malaysian students is challenging, and their help-seeking is low because of stigma. This study explored the relationships between mental health and positive psychological constructs (academic engagement, motivation, self-compassion, and wellbeing), and evaluated the relative contribution of each positive psychological construct to mental health in Malaysian students. An opportunity sample of 153 students completed the measures regarding these constructs. Correlation, regression, and mediation analyses were conducted. Engagement, amotivation, self-compassion, and wellbeing were associated with, and predicted large variance in mental health. Self-compassion was the strongest independent predictor of mental health among all the positive psychological constructs. Findings can imply the strong links between mental health and positive psychology, especially selfcompassion. Moreover, intervention studies to examine the effects of self-compassion training on mental health of Malaysian students appear to be warranted.N/

Phenoloxidase activity acts as a mosquito innate immune response against infection with semliki forest virus

Several components of the mosquito immune system including the RNA interference (RNAi), JAK/STAT, Toll and IMD pathways have previously been implicated in controlling arbovirus infections. In contrast, the role of the phenoloxidase (PO) cascade in mosquito antiviral immunity is unknown. Here we show that conditioned medium from the Aedes albopictus-derived U4.4 cell line contains a functional PO cascade, which is activated by the bacterium Escherichia coli and the arbovirus Semliki Forest virus (SFV) (Togaviridae; Alphavirus). Production of recombinant SFV expressing the PO cascade inhibitor Egf1.0 blocked PO activity in U4.4 cell- conditioned medium, which resulted in enhanced spread of SFV. Infection of adult female Aedes aegypti by feeding mosquitoes a bloodmeal containing Egf1.0-expressing SFV increased virus replication and mosquito mortality. Collectively, these results suggest the PO cascade of mosquitoes plays an important role in immune defence against arboviruses

Skin-impedance in Fabry Disease: A prospective, controlled, non-randomized clinical study

<p>Abstract</p> <p>Background</p> <p>We previously demonstrated improved sweating after enzyme replacement therapy (ERT) in Fabry disease using the thermo-regularity sweat and quantitative sudomotor axon reflex tests. Skin-impedance, a measure skin-moisture (sweating), has been used in the clinical evaluation of burns and pressure ulcers using the portable dynamic dermal impedance monitor (DDIM) system.</p> <p>Methods</p> <p>We compared skin impedance measurements in hemizygous patients with Fabry disease (22 post 3-years of bi-weekly ERT and 5 ERT naive) and 22 healthy controls. Force compensated skin-moisture values were used for statistical analysis. Outcome measures included 1) moisture reading of the 100^threpetitive reading, 2) rate of change, 3) average of 60–110^threading and 4) overall average of all readings.</p> <p>Results</p> <p>All outcome measures showed a significant difference in skin-moisture between Fabry patients and control subjects (p < 0.0001). There was no difference between Fabry patients on ERT and patients naïve to ERT. Increased skin-impedance values for the four skin-impedance outcome measures were found in a small number of dermatome test-sites two days post-enzyme infusions.</p> <p>Conclusion</p> <p>The instrument portability, ease of its use, a relatively short time required for the assessment, and the fact that DDIM system was able to detect the difference in skin-moisture renders the instrument a useful clinical tool.</p
