Abstract Reactive oxygen species causes harm to cell membranes and biomolecules, wherefore chronic diseases develop. Antioxidants scavenge such free radicals combating oxidative stress. This research aimed to determine the antioxidant potential of the aqueous stem bark, root and leaf extracts of Rhaphiolepis bibas against standards. DPPH radical scavenging activity was high from th stem bark extract at 72.33% with root extract at 65.85% and leaf extract at 55.91%, while ascorbic acid scavenged 89.53% of DPPH radicals.

Abstract:
After traumatic injuries to the brachial plexus there is a risk that one or more of the spinal roots are torn from the spinal cord, known as avulsion injury. This often leads to paralysis and chronic pain, notoriously difficult to treat with current pharmacotherapy. Surgical treatment may improve motor function but sensory recovery is usually poor as sensory axons fail to establish functional connections inside the spinal cord. The aims of this thesis were to develop a model for dorsal root avulsion in rodents in order to investigate the potentials of stem cell therapy for enhancing sensory re

Abstract:
Spinal root avulsion leads to paralysis and loss of sensory function. Surgical methods can improve motor function and ameliorate pain but sensory recovery in adults is poor. Previous studies have shown that cell transplantation or treatment with trophic factors can improve functional outcome in rodents after dorsal root transection or crush. Here, a dorsal root injury model, more similar to human avulsion injuries, was used. The aims of this thesis were to investigate the behaviour of different stem cells following transplantation to avulsed dorsal roots and asses their potential to serve as p

Continuing root growth is crucial for the ongoing survival of a plant and provides the structure basis for the acquisition of valuable resources such as water and nutrients required for growth and development.

This project focuses on the influence of phytohormone signalling upon the maintenance of the root apical meristem (RAM) in Arabidopsis thaliana.

The formation of neurospheres was important in demonstrating that neurogenesis in the adult brain may be fuelled by a stem cell population. The olfactory mucosa is another site of neurogenesis which, in humans, has been observed to contain a stem cell population through the formation of neurospheres (Murrell et al., 2005). Stem cells can be defined as cells capable of self-renewal and multipotency. The aim of this study was to investigate the potential of rat olfactory stem cells growing as neurospheres.

Abstract:
Representatives of the Seseli genus are recognized for their biological activities. The objective of this study was to analyze the phenolic and flavonoid content, along with the antioxidant effects, of methanol, ethyl acetate, and acetone extracts obtained from the roots, leaves, stems, and fruits of S. rigidum. Through spectrophotometric measurements of phenols and flavonoids, the results revealed that the polar (methanol) solvent extract from the leaves exhibited the highest concentrations of phenols (98.66 ± 2.64 mg GA/g) and flavonoids (20.74 ± 0.55 mg RU/g), surpassing those obtained from

Abstract:
Nasopharyngeal cancer (NPC) is a type of cancer that originates in the nasopharynx, which is the upper part of the throat behind the nasal cavity. Like other cancers, the growth and progression of nasopharyngeal cancer are influenced by various proteins involved in cell signaling, growth regulation, and tumor development such as Epidermal Growth Factor Receptor (EGFR), Vascular Endothelial Growth Factor (VEGF), Fibroblast growth factor receptor (FGFR) and Cyclin D1 (CD1). Megaphone ((1′R,5′R,7R,8S)-7-Hydroxy-3,4,5,5′-methoxy-5′,6′-dihydro-2′H-8,1′-neolign-8′-en-2′-one, MG) is the main componen

Medicinal plants and their different constituents are utilized as therapeutic agents. In present work we report the total phenolics content and screening of ninety five plant extracts for inhibitory activities against Clostridium histolyticum collagenase (ChC) and Bacillus polymyxa metalloprotease (BpM). Total phenolics content from plant methanolic extracts were assessed by using Folin-Ciocalteau assay. Screening of plant extracts for ChC and BpM inhibitory activities was performed by using dot blot assay on X-ray film. G. superba fruit was observed to have the highest phenolics (257.58 ± 0.7

Stinging nettle is a highly nutritious vegetable due to its increased use in different food products and its health-promoting properties. Nettles are highly adaptable occurring in most common areas from unpolluted to highly polluted areas, along stream banks, farmland and also in highly disturbed areas. In hot areas, they prefer sites in partial shade, but accept to grow also in full sun, mostly in moist soils alongside streams or in drains. U. dioica develops ea

Abstract:
Abstract In many additive manufacturing processes, surface roughness is a critical quality concern. Due to the nature of the layer-by-layer manufacturing process, the pattern of surface roughness depends on the location on the surface, i.e., the layer number and the location within each layer. Adequate description of the surface roughness enables us to develop effective post-processing plans, reveal the root causes of the roughness, and generate accurate compensation schemes. In this work, we propose a three-step surface roughness characterization method (SRCM). This method is based on the den

Abstract:
Wide-angle parabolic equations (WAPEs) play an important role in physics. They are derived by an expansion of a square-root pseudo-differential operator in one-way wave equations, and then solved by finite-difference techniques. In the present paper, a different approach is suggested. The starting point is an extra-wide-angle parabolic equation (EWAPE) valid for small variations of the refractive index of a medium. This equation is written in an integral form, solved by a perturbation technique, and transformed to the spectral domain. The resulting split-step spectral algorithm for the EWAPE a

Abstract:
Soilless crop production in protected cultivation requires optimization of many environmental and plant variables. Variables of the root zone (rhizosphere) have always been difficult to characterize but have been studied extensively. In soilless production the opportunity exists to optimize these variables in relation to crop production. The project objectives were to model the relationship between biomass production and the rhizosphere variables: temperature, dissolved oxygen concentration and water availability by characterizing potential growth and how this translates to actual growth.
