The integrated intensities of mineral phase (phosphate and carbonate bands at 959 and 1,071 cm(-1), respectively) and organic phase (amide I band at 1,665 cm(-1)) Raman bands were analyzed. The mineral-to-matrix
(phosphate/amide I), carbonate-to-phosphate, and carbonate-to-amide I ratios were analyzed to assess bone quality. The phosphate content on trabecular bone was higher in the CRE group than the OVX group (p < 0.05). No significant changes in mineral or organic phases on cortical bone were observed. A radiographic assessment of bone density was encouraging as the same findings were showed by Raman intensity of phosphate from cortical (r (2) = 0.8037) and trabecular bones (r (2) = 0.915). Severe ovariectomy-induced bone loss was confirmed by FT-Raman spectroscopy. The results suggest that the chemical composition of trabecular bone tissue may be positively influenced by Cr supplementation after ovariectomy.”
“The thin-walled structure of veins leads VX-689 them to stay collapsed during anastomoses, thereby the incidence of technical failures is more common than arterial anastomoses. In order to overcome this ACY-241 problem, we are introducing the use of viscoelastic material based on our experience on rats. Six rats were used in order to study the technical feasibility of the viscoelastic material during microsurgical vein anastomosis. End-to-end anastomoses were
performed on rat jugular veins using 0.5-1 mL of the viscoelastic medium applied to the ends of the veins and surgical field
under X30 operating microscope magnification. Then 1.8% (n:3) and 3.0% (n:3) hyaluronic acid was used as a viscous medium in order to keep the vein lumens open during anastomosis. In conclusion, we have found that 3.0% hyaluronic acid viscoelastic medium facilitates microvenous anastomosis in rat. Studies involving human practice are needed for further evaluation of this technical refinement.”
“While some studies have shown that long-limb gastric bypass with Roux limb length of 150 to 200 cm can attain better weight loss outcomes in super-obese patients (BMI > 50 kg/m(2)) than the standard limb gastric bypass with Roux limb length of 100 to 150 cm, other studies have not shown similar findings. Additionally, no study has demonstrated the optimal length find more of the Roux limb that will result in ideal weight loss. The purpose of this study is to compare the long-term weight loss and weight regain of standard limb length (SLL) and long limb length (LLL) gastric bypass in patients with BMI > 50 kg/m(2).
A total of 120 patients with BMI > 50 kg/m(2) underwent either SLL (total bypass length = 200, biliopancreatic limb = 50-80 cm, Roux limb = 120-150 cm) or LLL (total bypass length = 250 biliopancreatic limb = 50-80 cm, Roux limb = 170-200 cm) RYGB. The excess weight loss (EWL), the weight regain, and the rate of complications were measured at 1-, 2-, and 3-year follow-up. Statistical comparisons were performed using t-test.
