Abstract
BACKGROUND Fennel essential oils are fragrance compounds used in food and pharmaceutical sectors. One of the major impediments to expansion of fennel farming in Egypt's reclamation areas is saline water. Titanium dioxide (TiO2) or TiO2 nano particles (TiO2NP) can be utilized to boost the yield of aromatic plants cultivated under saline irrigation water. Saline water, particularly which contains sodium chloride can harm fennel plant; consequently, it was predicted that fennel production would fail in Egypt's reclaimed area, where the primary source of irrigation is groundwater consisting sodium chloride. This study sought to help fennel respond to sodium chloride by applying Ti forms to their leaves in order to reduce the detrimental effects of sodium chloride on them for expanding their production in the newly reclamation areas as a natural source of essential oil. Ti forms were applied as foliar application at 0, 0.1, 0.2 TiO2, 0.1 TiO2NP, and 0.2 TiO2NP, mM under irrigation with fresh water (0.4 dS m-1), or saline water (51.3 mM or 4.7 dS m-1). RESULTS Plants exposed to 0.1 mM TiO2NP under fresh water resulted in the maximum values of morphological characters, estragole, oxygenated monoterpenes and photosynthetic pigments; while those subjected to 0.1 mM TiO2NP under saline water gave the greatest values of essential oil, proline, antioxidant enzymes and phenols. The greatest amounts of soluble sugars were recorded with 0.2 mM TiO2NP irrigated with saline water. Plants subjected to 0 mM TiO2 under saline water produced the greatest values of flavonoids, hydrogen peroxide and malondialdehyde. CONCLUSION To mitigate the negative effects of salty irrigation water on fennel plant production, TiO2NP application is suggested as a potential strategy.

Abstract
Chamomile essential oil is used in the food and medicinal industries. Gallic acid has been identified as one of the most significant biological elicitors. At dosages of 0, 5, 10, 15, and 20 mg/L, Gallic acid was sprayed on chamomile plants. The yield of flowers and essential oils in dry flowers were assessed. The averages of data were examined statistically using one-way analysis of variance. Oxygenated sesquiterpenes were a major chemical group, while α-bisabolol oxide A, α-bisabolol and chamazulene were the three main components of essential oil. When administered 15 mg/L Gallic acid, plants produced their most flowers and had the highest quantities of the essential oil, α-bisabolol oxide A, α-bisabolol and chamazulene. Essential oil extracted from untreated control plants had the highest concentration of oxygenated sesquiterpenes. It can be infer that Gallic acid increases the production of essential oil and alters its chemical constituents which alter its biological activity.

Abstract
Essential oil of geranium (Pelargonium graveolensL) has biological activities that make it used in food and pharmaceutical manufactures. High salinity is one of the factors that lead to lack of expansion in the production of medicinal and aromatic plants, especially in the new reclaimed soil located at arid and semi arid regions. Glutathione is a natural antioxidant that can help plants to withstand unfavorable environmental conditions such as the salinity of irrigation water. This trial aimed to diminish the undesirable effect of exposure to irrigation with salt water on geranium herbs through subjected them to exogenous application of glutathione. Geranium plants were irrigated with various concentrations of salt water with sodium chloride (0.0, 34.2, 51.3, and 68.4 mM) without (0 mg/L) or with glutathione (375 mg/L). Plants exposed to various rates of saline irrigation water with glutathione resulted in higher values of growth criterions (fresh and dry aerial parts), photosynthetic pigments, carbohydrates, protein, proline, essential oil (% or yield), antioxidant enzymes (peroxidase and superoxide dismutase), nitrogen, phosphorous, potassium, calcium, iron, zinc, manganese and copper than those subjected to saline irrigation water without glutathione. Higher amounts were found in sodium and chloride of plant treated with saline irrigation water than those treated saline irrigation water with glutathione. It may be summarized that productivity of geranium plants can be improved with adapting them under saline irrigation conditions by adding glutathione. This trial benefits the producers of geranium to alleviate the hurtful effects of salinity in reclaimed regions with adding glutathione.

Abstract
Sclerostin has emerged as an important regulator of bone mass. We have shown that sclerostin can act by targeting late osteoblasts/osteocytes to inhibit bone mineralization and to upregulate osteocyte expression of catabolic factors, resulting in osteocytic osteolysis. Here we sought to examine the effect of exogenous sclerostin on osteocytes in trabecular bone mechanically loaded ex vivo. Bovine trabecular bone cores, with bone marrow removed, were inserted into individual chambers and subjected to daily episodes of dynamic loading. Cores were perfused with either osteogenic media alone or media containing human recombinant sclerostin (rhSCL) (50 ng/ml). Loaded control bone increased in apparent stiffness over time compared with unloaded bone, and this was abrogated in the presence of rhSCL. Loaded bone showed an increase in calcein uptake as a surrogate of mineral accretion, compared with unloaded bone, in which this was substantially inhibited by rhSCL treatment. Sclerostin treatment induced a significant increase in the ionized calcium concentration in the perfusate and the release of β-CTX at several time points, an increased mean osteocyte lacunar size, indicative of osteocytic osteolysis, and the expression of catabolism-related genes. Human primary osteocyte-like cultures treated with rhSCL also released β-CTX from their matrix. These results suggest that osteocytes contribute directly to bone mineral accretion, and to the mechanical properties of bone. Moreover, it appears that sclerostin, acting on osteocytes, can negate this effect by modulating the dimensions of the lacunocanalicular porosity and the composition of the periosteocyte matrix.

Abstract
This paper chronicled the development of a locally produced bone graft substitute based on calcium phosphate bioceramics called "GranuMaS--from concepts to clinics, and finally to its successful commercialization all within 5-year duration. It was a Prioritized Research (PR) collaborative project of 5 institutions namely SIRIM, ANM, USM, UKM and IIUM, funded by MOSTI to the amount of approximately RM2.5 millions under RM8. This paper also highlighted the requirements needed in terms of technical expertise/manpower, facilities and infrastructure, and government/institutional supports, as well as the challenge faced in developing and commercializing such product.

Abstract
This study is to qualitatively evaluate a locally produced hydroxyapatite (HA), made by AMREC-SIRIM in an experimental animal bone defect using New Zealand White (NZW) rabbits. HA cylindrical blocks measuring 2.5 mm (D) x 1.0 mm (H) were implanted in the rabbits' left tibia. The tibias were harvested within one to three weeks post-implantation. The implantion site was cut into thin undecalcified sections of about 30 microm to 60 microm and stained with Toluidine Blue and Goldner's Masson Trichrome. Microscopic examinations using standard light microscopy of these slides were performed.

Abstract
Hydroxyapatite is a calcium phosphate bioceramic that has been shown by many authors to be biocompatible with bioactive properties. It is widely accepted as the best synthetic material available for surgical use as a bone graft substitute. HA granules produced by AMREC-SIRIM from local materials underwent 5 types of sterilisation techniques with different ageing periods. Samples were tested for chemical and phase composition and microbial contamination before and after being sterilised. From the microbiological tests done, none of the unsterilised positive control yielded a positive culture. Results from X-Ray diffraction studies found that all the sterilisation techniques did not chemically degrade or structurally change the HA granules significantly.
