Polyphenols were extracted from Pomegranate peels and then encapsulated by ionic gelation. The aqueous extract and the microbeads were used for the preparation of fortified milk. All beverages were kept in refrigerator and the shelf life of milk in terms of polyphenols content was studied. Results showed that 62.23% of polyphenols remained stable for 11 days in milk fortified with alginate-pectin (2:1) microbeads, while only 38.13% and 5.47% of polyphenols remained stable in milk fortified with sodium alginate microbeads and aqueous extract, respectively. Results also suggest that the formation of milk protein-polyphenol complexes compromises the antioxidant potential of the beverage. © Mattioli 1885.

Nutrition and Cancer | Year: 2017

Cancer remains one of the leading causes of death around the world. Initially it is recognized as a genetic disease, but now it is known to involve epigenetic abnormalities along with genetic alterations. Epigenetics refers to heritable changes that are not encoded in the DNA sequence itself, but play an important role in the control of gene expression. It includes changes in DNA methylation, histone modifications, and RNA interference. Although it is heritable, environmental factors such as diet could directly influence epigenetic mechanisms in humans. This article will focus on the role of dietary patterns and phytochemicals that have been demonstrated to influence the epigenome and more precisely histone and non-histone proteins modulation by acetylation that helps to induce apoptosis and phosphorylation inhibition, which counteracts with cells proliferation. Recent developments discussed here enhance our understanding of how dietary intervention could be beneficial in preventing or treating cancer and improving health outcomes. © 2017 Taylor & Francis Group, LLC.

In this study, finite element analysis (FEA) was used to evaluate nine rigid internal fixation techniques for sagittal split ramus osteotomy. To achieve this, a computed tomography (CT) scan of a healthy patient was obtained and used to generate the geometry of a half-mandible. The geometries of bicortical screws, miniplates, and monocortical screws were designed and combined with the mandible in nine models simulating various techniques. Four models used bicortical screws in various arrangements and four used miniplates of various designs. One model represented a hybrid technique. A load of 500 N was applied to the posterior teeth and FEA was applied. The most stable techniques were the hybrid technique and a single straight miniplate, presenting the least displacement among all models. Bicortical screws, while presenting reasonable stability, showed high strain areas near the anterior ramus ridge, superoposterior to the screws, implying a risk of bone fracture in this area. On the other hand, the T-shaped and double Y-shaped miniplates were associated with high von Mises stresses that would impair their rigidity, especially where angles appeared in their designs. We recommend the use of a single straight miniplate because it provides sufficient stable fixation with minimal risks or disadvantages. © 2015 International Association of Oral and Maxillofacial Surgeons.

This study was conducted to evaluate the use of plasma rich in growth factors (PRGFs) with immediate implant placement in periodontally compromised extraction sites. Fifteen patients with chronic periodontitis were included. Each received two implants placed immediately after extraction in the anterior region of the mandible. One of the two implants was treated with PRGFs (group I), while the other was not and served as a control (group II). Implant survival, plaque index (PI), bleeding index (BI), probing pocket depth (PPD), and marginal bone loss (MBL) were evaluated for both groups. Complete soft tissue healing occurred in all patients and all implants were successfully osseointegrated over 12 months. At 12 months, results showed mean PPD values of 3.8 ± 0.3 mm at the control site (group II) and 3.4 ± 0.4 mm at the test site (group I); the mean MBL values were 1.1 ± 0.1 mm at the control site and 0.6 ± 0.1 mm at the test site. There were no statistically significant differences between the test and control groups regarding PI or BI, while there were statistical differences between the test and control groups regarding PPD and MBL throughout the follow-up period. © 2014 International Association of Oral and Maxillofacial Surgeons.

Large insertions/deletions mutations are frequently found in genes associated with certain diseases such as hereditary cancers. These mutations are mostly overlooked by current classical screening techniques due to their certain limitations. This justifies the need to improve the existing techniques or design novel ones. A modified version of quantitative multiplex PCR short fluorescent fragment (QMPSF), termed universally primed QMPSF (upQMPSF), was developed. The modifications enhance multiplexing capacity, reduce cost, and improve the mutation detection spectrum. upQMPSF was used to screen germline mutations in 88 familial ovarian cancer patients negative for point mutations. upQMPSF successfully detected a 2.8 kb copy number gain spanning exon 15 of BRCA1 gene mediated by Alu–Alu homologous-based recombination. upQMPSF is a cost-efficient, versatile method, and demonstrated efficiency in detecting structural variations as a potential method for genetic testing in clinical and research laboratories. © 2015, Springer Science+Business Media New York.

A method was designed for the determination the amount of nickel in bronze. It was based on the adsorption of nickel on positive ion exchange of strong acid Amberlit CG-120 in form-H. HCl:acetone medium at pH=1 was used in order to separate other positive ions as chloride complexes. The fluids were filtered and the cation exchanger was treated with ammonium buffer solution pH=8-9, then it was treated with an ethanolic solution of Dimethylglyoxime. The determination of Nickel content was carried out using a spectrophotometer. Results indicated a content of 0.29±0.02%, whereas the nickel theoretical content was 0.31%. Using IR spectra, it was found that the adsorption of nickel on Amberlit CG-120 was due to covalent bonds with groups-SO3-, in the form of ammonium complexes. © 2015, SPB Pharma Society.

Objective: The purpose of this review is to discuss the dosage, duration and carrier for simvastatin, and to summarize effects of topical application directly or indirectly for stimulating bone regeneration. Methods: We have searched in Pubmed using keywords, simvastatin, dose response, bone regeneration, controlled-release delivery system. This search was complemented with a manual search of the relevant articles cited among the selected papers. The search was among the articles written in English and published in the last 10 years. The articles were revised in depth, and summarized. Results: High dose of simvastatin increases bone formation and resorption, while low dose of simvastatin decreases bone formation and increases bone resorption, furthermore it is reported that high dose of systemic administration of simvastatin will raise the risk of liver failure, kidney disease, and other side effects. Local administration can bypass hepatic degradation of statins to achieve therapeutic concentrations in bone and avoid the systemic side effects. The choice of appropriate carrier will depend on the release kinetics determined to be the best for osteogenesis. Conclusion: Local delivery of simvastatin from carriers appears to be an attractive solution to the problem of maintaining therapeutic doses to treat severe bone defects and to minimize the undesired side effects. Locally delivered simvastatin can increase the bone formation and accelerate healing process of bony defect. Another advantage of local delivery system is that it can stimulate new bone formation in a dose-dependent manner. Further evidence-based studies will be required to determine local delivery concentrations to promote bone regeneration. © 2015 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

Background: Melanoma is a leading fatal illness responsible for 80% of deaths from skin cancer. It originates in the pigment-producing melanocytes in the basal layer of the epidermis. Melanocytes produce the melanin (the dark pigment), which is responsible for the color of skin. As all cancers, melanoma is caused by damage to the DNA of the cells, which causes the cell to grow out of control, leading to a tumor, which is much more dangerous if it cannot be found or detected early. Only biopsy can determine exact malformation diagnosis, although it can rise metastasizing. When a melanoma is suspected, the usual standard procedure is to perform a biopsy and to subsequently analyze the suspicious tissue under the microscope. Methods: In this paper, we provide a new approach using methods known as 'imaging spectroscopy' or 'spectral imaging' for early detection of melanoma using two different supervised classifier algorithms, maximum likelihood (ML) and spectral angle mapper (SAM). SAM rests on the spectral 'angular distances' and the conventional classifier ML rests on the spectral distance concept. Results and conclusions: The results show that the ML classifier was more efficient for pixel classification than SAM. However, SAM was more suitable for object classification. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In this paper, we propose a practical way to synthesize and filter an ECG signal in the presence of four types of interference signals: (1) those arising from power networks with a fundamental frequency of 50. Hz, (2) those arising from respiration, having a frequency range from 0.05 to 0.5. Hz, (3) muscle signals with a frequency of 25. Hz, and (4) white noise present within the ECG signal band. This was done by implementing a multiband digital filter (seven bands) of type FIR Multiband Least Squares using a digital programmable device (Cyclone II EP2C70F896C6 FPGA, Altera), which was placed on an education and development board (DE2-70, Terasic). This filter was designed using the VHDL language in the Quartus II 9.1 design environment. The proposed method depends on Direct Digital Frequency Synthesizers (DDFS) designed to synthesize the ECG signal and various interference signals. So that the synthetic ECG specifications would be closer to actual ECG signals after filtering, we designed in a single multiband digital filter instead of using three separate digital filters LPF, HPF, BSF. Thus all interference signals were removed with a single digital filter. The multiband digital filter results were studied using a digital oscilloscope to characterize input and output signals in the presence of differing sinusoidal interference signals and white noise. © 2015 Elsevier Ltd.

There are several generics of metformin hydrochloride tablets available within the drug delivery system globally. Numerous brands of Metformin tablets (850mg) are available in the Syrian drug market. The objective of this study is to determine the biopharmaceutical and chemical equivalence of five brands of Metformin tablets marketed in Syria. The physicochemical equivalence of five brands of Metformin hydrochloride tablets were assessed through the evaluation of both official and non-official standards such as weight variation, friability, hardness, content uniformity, and dissolution rate. All the brands complied with the official specifications for weight variation and friability tests. The result indicates that only two (B & E) brands passed the non-official test of crushing strength/hardness while the remaining brands (A, C & D) failed. Three brands had values within the range specified (95-105%) for content uniformity in the USP while brands (A & D) failed the test. Three tested brands released more than 75% drug in 30 minutes except brand A and brand C; therefore, all formulations excluding formulation A, and C passed this acceptance pharmacopeia criterion (USP).
