Brown rice is a good source of dietary fibre (DF) and contains higher vitamins/minerals than milled rice. The study determined the effect of amylose content (AC) and DF on glucose response (GR) from different varieties of milled and brown rice. Milled and brown rice were used as test foods. They were fed to 9-10 human volunteers containing 50 g available carbohydrate after an overnight fast. GR and the glycemic index (GI) were determined. Results found that Sinandomeng with the lowest AC had a high GI = 75, while PSBRc10 with the highest AC had a low GI = 50. Sinandomeng with a low DF had GI = 75, while its brown rice had GI = 55. Brown rice (IR64) with 23% AC and DF of 2.5 g/100 g had low GI = 51. In conclusion, the GR and GI of the different varieties of cooked milled and brown rice varied depending on its AC and DF contents. © 2012 Informa UK, Ltd.

Introduction: Both cross-sectional and prospective studies have shown that diabetes specifically is associated with a decrease in bone mineral density (BMD) and an increased risk of osteoporotic hip and other fractures. This study was undertaken to assess the bone strength and prevalence of fracture in premenopausal women aged 30-50 years with diabetes as they transition through menopause. Materials and Methods: This study compared the BMD and history of fracture among premenopausal women aged 30-50 years with and without diabetes. Study participants were composed of 33 premenopausal women aged 30-50 years with diabetes and 30 age-matched pre-menopausal women without diabetes, who have under gone BMD assessment as supported by DEXA results. Descriptive characteristics (means + SD) analysis was used to characterize the participant's demographic, lifestyle and metabolic characteristics as well as BMD. T-test was used to compare values (demographic, lifestyle, and metabolic characteristics) between diabetic and non-diabetic participants and to see if differences exist between the BMD of both groups. Results: Statistical results revealed that non-diabetic subjects showed a higher bone mineral density for all three sites identified as lumbar spine, right and left femoral neck compared with diabetic subjects although no significant difference in the BMD between diabetic and non-diabetic subjects was found. Having diabetes increases a patient's risk of developing an osteoporosis-related fracture due to lowering of bone mineral density.

Based on ISO Guide 43-1: 1997 and ILAC G-13: 2000 guidelines three (3) proficiency test (PT) Rounds were organized for moisture, fat, protein, ash, iron, calcium and sodium analyses using wheat flour (Round 1), powdered tonic food drink (Round 2) and dried paste shrimp (Round 3) as PT materials. Fifty-three (53), fifty-two (52) and forty-six (46) local and foreign laboratories participated in PT Rounds 1, 2 and 3, respectively. Results were evaluated using the appropriate statistical procedures based on ISO 13528: 2005 and/or IUPAC Technical Report, 2006. The z-scores used to evaluate the performance of participant laboratories were computed, applying the standard deviation for proficiency test assessment (σp) derived from the CVs/RSDs of previous PTs and the general expression of Horwitz, while the assigned values (robust mean or mode with uncertainty) were obtained from the consensus of PT participants' results. For proximate analyses, 65-90% of PT participant laboratories achieved " satisfactory" (vz-scorev≤2) performance for the three (3) PT Rounds. For iron and calcium analyses, only 50-70% achieved " satisfactory" performance. The PT test materials' given assigned values (X) and range (X±2σp) were used in method validation and as quality control test materials by the local laboratories. The three (3) PT Rounds provided an effective tool in assessing the laboratory performance of proximate and mineral analyses and in conducting the necessary investigative and corrective action on " questionable" (" Q" ) and " unsatisfactory" (" U" ) results. © 2010 Elsevier Inc.
