Background to Study: Lead (Pb) is ubiquitous in the environment and toxic. It has many negative effects on many organs and induces biochemical, physiological, and behavioural alterations on the brain. Monodora myristica is a calabash nutmeg belonging to the family of Annonaceae.It is a rich source of flavonoids which have been shown to exhibit both antioxi-dant and anti-inflammatory properties. We evaluated the protective role of Monodora myristica on lead-induced toxicity in D. melanogaster in this study

The optimal design of heliostat field in solar power generation device is studied Heliostat field generates high temperature by focusing the sunlight reflected from the mirror surface, thus pushing the turbine to generate electricity. In order to improve the efficiency of power generation, this paper optimizes the parameters of heliostat field, establishes a singleobjective optimization model, and uses mixed strategy whale optimization algorithm to solve it. Through geometric optical analysis and ray tracing model, the optical efficiency of heliostat field and the annual average output thermal power per mirror area are calculated. Finally, through the discussion and analysis of the model, the optimization design method is evaluated.

The results obtained from heavy metal pollution assessment of River Ureje using Heavy Pollution Index (HPI) and Contamination Index (Cd ). HPI values at upstream and downstream point of the river, Cd, Pb, Cr had high pollution load that exceeded threshold value of 100 while Mn, Cu, Zn, Ni had low pollution index which are below threshold value. This indicated that high pollution status of Cd, Pb, Cr were observed because they compete with other essential metallic cations for binding sites and inhibits enzyme activity while there is no pollution presence of Zn, Mn, Ni, Cu. Cd value results in both upstream and downstream point revealed that Zn, Cd, Cu, Pb had a low contamination index below <1 contamination value and tends to show no effect on aquatic environment and drinking water quality. However, Cr, Ni had medium contamination compared to (Cd=1-3) Cd value, this indicates slight contamination of these heavy metals and have slight effect on drinking water quality and aquatic life present while Manganese had high Cd value compared to (Cd>3) Cd value which to tends have high effect on drinking water quality and aquatic system. In conclusions, this study revealed that High level of HPI above critical index value was observed for Cd, Cr, Pb while Mn shows high Cd far above contamination index value.

Using kinetic differential equations and the Runge-Kutt algorithm, an analysis of the pathological processes occurring in the course of Alzherimer’s disease was carried out. Thanks to the appropriately selected kinetic equations, the presented model allows to explain the time course of the growth of pathological proteins: beta-amyloid and tau protein and the related loss of nerve cells. The model is based on previous experimental knowledge of Alzherimer’s diseas and is in good agreement with the experimental data.

This study aimed at assessing variability among morphometric traits, deducing components that describe these traits and predicting bodyweight from both original and orthogonal traits using regression models. Bodyweight and fifteen morpho- metric traits namely height-at-whither (HW), body-length (BL), chest-depth (CD), chest-girth (CD), rump-length (RL), rump-height (RH), pelvic-width (PW), shoulder-width (SW), head-width (HdW), head-lengthHdL), cannon-bone-length (CBL), cannon-bone-circumference (CBC), ear-length (EL), horn-length (HL), tail-length (TL), and tail-circumference (TC) were recorded on 600 extensively managed and randomly selected adult sheep.

Purpose: We aimed to create mechanic optic nerve injury model in rats and investigate the neuroprotective effects of ripasudil on retinal ganglion cells. Study Design: Experimental study Methods: Mechanic optic nerve injury model was created in the right eyes of male Wistar rats (n=15). Rats were divided into three groups: glaucoma model with sham treatment (group1) and 20 µM intravitreal ripasudil treatment (group 2) and 50 µM intravitreal ripasudil treatment (group 3). Treatment was applied intravitreally and rats were sacrificed at the end of 4 weeks. Glial fibrillary acidic protein (GFAP), Brn-3a antibody,anti- Iba1 was examined by immunohistochemistry. Results: The number of Brn-3a positive RGC in the mechanical optic nerve injury model was 5.33 ± 2.08 (min: 3, max: 7) in sham group, 10.25 ± 2.63 (min: 8, max: 14) in 20 µM group and 16.75 ± 5.43 (min:9, max: 21) in 50 µM group (p <0.05). GFAP positive RGC counts were recorded as 24.33 ± 2.08 (min: 22, max: 26) in sham group, 16.75 ± 1.70 (min: 15, max: 19) in 20 µM group and 13.00 ± 4.08 (min:10 , max: 19) in 50 µM group (p <0.05). Ripasudil treatment also decreased Iba1 expression in the retina of mechanic optic nerve injury groups. In addition, ripasudil treatment prevented apoptotic cell death by increasing Bcl-xL protein expression and preserved Tfam protein expression in the retina. Conclusions: Our experimental study has shown that ripasudil is neuropreotective in mechanical optic nerve injury model.

The Lord-Shulman theory with one relaxation time and the dual-phase-lag model with two relaxation times of thermoelasticity are used in this article to study the influence rotation micro-elongated thermoelastic layer, when a piezo electric layer is above it. To convert a partial differential equation to an ordinary differential equation, the normal mode method is utilized. Numerical computations are implemented for aluminum epoxy, and the results are charted. A comparison is made among the two theories in the complete absence and the presence of a rotation. The presence of a rotation has a major effect on all physical quantities.

Chronic wounds substantially reduce the quality of life for millions of people worldwide. As a result, researchers have developed various treatments and therapies to reduce the time for a wound to heal. Mathematical models that help better understand and predict the wound healing process have also been developed. This paper presents and validates a mathematical model known as the vibration enhanced wound healing model (VEWH) that includes the effects of vibration treatment in the wound healing process. The model is based on existing models of cutaneous wound healing but includes the effects of vibration on blood flow, macrophages, chemoattractant, and fibroblasts. These parameters were derived from published data on vibration accelerated wound healing of healthy mice. The VEWH model is confirmed with published experimental animal data that show vibration can reduce the wound healing time by 8%. The model reveals that vibration primarily affects healing through the mechanotransduction of vibration by fibroblasts into greater production of extracellular matrix. Model simulations agree with the validation data, with optimal healing predicted to occur with frequencies between 5 Hz and 25 Hz.
