The effect of Topical Application of Honey Based Gel Containing Zingibar Officinale for Non Surgical Periodontal Maintenance

Introduction: Ginger and honey have shown to be effective against pathogens routinely encountered in periodontal infection. However, none of literature has shown antibacterial effect of ginger and honey on the levels of dental plaque when used as a gel. Aim: To compare the effect of honey with ginger extract on the dental plaque levels and gingival health. Methodology: Fifteen systemically healthy patients were randomly allocated to either the test group [G1(ginger and honey gel = 15 sites)] or the control group [G2 (Chlorhexidine gel = 15 sites]. Full mouth Gingival Index (GI) Full mouth Plaque Index (PI) were evaluated at baseline and on 7th day. Results: The mean PI at baseline was 0.23 ± 0.02 (G1) and 0.29 ± 0.01 (G2) which was increased to 0.36 ± 0.01 (G1) and 0.37 ± 0.01 (G2) on 7th day. However, mean GI at baseline was 0.30 ± 0.04 (G1) and 0.34 ± 0.02 (G2) which was increased to 0.38 ± 0.03 (G1) and 0.43 ± 0.03 (G2) on 7th day. Conclusion: The results of this study suggest that the chlorhexidine gel and Natural gel containing Honey and Zingibar officinale both are effective in controlling plaque during the periodontal maintenance period.

Textile-Based Battery Using a Biodegradable Gel-Electrolyte

Lightweight and flexible batteries with natural gel-electrolyte between textile-based electrodes are presented, demonstrating a discharge capacity of 100 mAh g-1 at 14 mA g-1 with respect to the anode. Aging processes of the gel-matrix are investigated, showing that the device can be refreshed by re-wetting the gel-electrolyte. Due to the textile-based architecture, the batteries can be bent up to 180° with minor influence on the battery voltage.

Research on a Coated Method for Ceramic Proppant

Due to the disadvantage of the traditional proppant, such as the low strength, poor acid corrosion resistance, embedding and flowback and so on, a new coated proppant was developed to deal with these problems. As the coating material, the natural gel was used to coat proppant. Different from the traditional mechanical mixing method, the means to make coated ceramic was the solvent dispersion method through the process of emulsification, cross-linking and dehydration dispersion. The strength of coated proppant was tested in different coated conditions. According to the result of test, the ceramic was coated under the optimum condition. Then the roundness, sphericity, acid solubility, crush resistance and surface structure of coated ceramic were compared with the uncoated ceramic. The experimental results showed that the optimal condition was as follows: 0.08 g/ml of gel concentration, 15/2 of ceramic/gel (g/g), 0.025 g/ml of emulsifier concentration, 20min of emulsifying time, 1/10 of water/oil rate. The coated ceramic prepared at this condition had the best performance, compared with the common ceramic, and its sphericity and acid solubility were greatly improved, bulk density reduced 7%. And the proppant surface was very smooth, the crush resistance was almost zero.

Characterization of mucoadhesive nasal gels containing midazolam hydrochloride prepared from Linum usitatissimum L. mucilage

Nasal drug delivery systems prepared from natural materials are gaining importance in the field of pharmaceutical technology. Mucilage isolated from Linum usitatissimum L. (LUM) seeds was reported to be an effective natural mucoadhesive agent. The present study deals with a comparison of various characteristics of nasal gels containing midazolam hydrochloride (HCl) prepared from mucoadhesive agent extracted from Linum usitatissimum L. seeds and synthetic polymers like HPMC and Carbopol 934P in terms of texture profile analysis, mucoadhesive strength, and in vivo drug absorption profiles. It was observed that gels formulated with the natural mucilage showed better results than the synthetic gels in all aspects like hardness, adhesiveness, cohesiveness and mucoadhesive strength. The absolute bioavailability of midazolam hydrochloride from the natural gel was 97.55% whereas that of synthetic gels was 57.33% and 76.81% respectively.
