Abstract Background Liquid oral pediatric medicines (LOPM) contain sucrose and glucose and can have a low pH; their chronic administration may increase the risk for dental caries and erosion in children. The aim of this study was to determine sucrose and glucose concentrations, and pH of LOPMs of long-term use by children. Methods A cross sectional survey was conducted among 95/381 pharmacies to assess the most commonly prescribed LOPM by pharmacists in North Jordan, yielding 42 medicines which were analyzed for sucrose and glucose concentrations (mg/g) using HPLC-RID, and pH measurement using pH-meter CP-505. Data were analyzed using SPSS version 19.0. Differences were considered significant at P ≤ 0.05. Results The lowest and highest sucrose concentrations were for Ramlac® (0.9%) from the gastrointestinal medicines and Varolex® (79.5%) from the nutritional medicines, respectively. The lowest and highest glucose concentrations were for Adol® (0.0%) from the central nervous medicines and Pediavit-D® (81.1%) from the nutritional medicines, respectively. The pH ranged from 3.2 for Varolex® from the nutritional medicines to 10.0 for Zithromax® from the antibiotics medicines. Conclusions Some of the LOPMs studied had high sucrose or glucose concentrations (or both) and low pH which could increase their potential of causing dental caries and erosion when ingested frequently and chronically.

Myopia Control

Orthokeratology lenses are commonly used for myopia control, especially in children. Tear lipids and proteins are immediately adsorbed when the lens is put on the cornea, and protein deposition may cause discomfort or infection. Therefore, we established an in vitro protein deposition analysis by mimicking the current cleaning methods for orthokeratology lens wearers for both short-term and long-term period. The results showed that the amounts of tear proteins accumulated daily and achieved a balance after 14 days when the lens was rubbed to clean or not. Protein deposition also affected the optical characteristics of the lens regardless of cleaning methods. Our results provided an in vitro analysis for protein deposition on the lens, and they may provide a potential effective method for developing care solutions or methods that can more effectively remove tear components from orthokeratology lenses.

A detailed understanding of the mechanism of protein synthesis will ultimately depend on knowledge of the native structure of the ribosome. Towards this end we have investigated the low resolution structure of the eukaryotic ribosome embedded in frozen buffer, making use of a system in which the ribosomes crystallize naturally.The ribosomes in the cells of early chicken embryos form crystalline arrays when the embryos are cooled at 4°C. We have developed methods to isolate the stable unit of these arrays, the ribosome tetramer, and have determined conditions for the growth of two-dimensional crystals in vitro, Analysis of the proteins in the crystals by 2-D gel electrophoresis demonstrates the presence of all ribosomal proteins normally found in polysomes. There are in addition, four proteins which may facilitate crystallization. The crystals are built from two oppositely facing P4 layers and the predominant crystal form, accounting for >80% of the crystals, has the tetragonal space group P4212, X-ray diffraction of crystal pellets demonstrates that crystalline order extends to ~ 60Å.

SummaryThe variability of the platelet GP Ia/IIa density has been associated with the 807 C/T polymorphism (Phe 224) of the GP Ia gene in American Caucasian population. We have investigated the genotype and allelic frequencies of this polymorphism in Spanish Caucasians. The T allele was found in 35% of the 284 blood donors analyzed. We confirmed in 159 healthy subjects a significant association between the 807 C/T polymorphism and the platelet GP Ia density. The T allele correlated with high number of GP Ia molecules on platelet surface. In addition, we observed a similar association of this polymorphism with the expression of this protein in other blood cell types. The platelet responsiveness to collagen was determined by “in vitro” analysis of the platelet activation and aggregation response. We found no significant differences in these functional platelet parameters according to the 807 C/T genotype. Finally, results from 3 case/control studies involving 302 consecutive patients (101 with coronary heart disease, 104 with cerebrovascular disease and 97 with deep venous thrombosis) determined that the 807 C/T polymorphism of the GP Ia gene does not represent a risk factor for arterial or venous thrombosis.
