Fast Reflectance Spectral Profile Reconstruction Method for Full-waveform Hyperspectral LiDAR by Hui SHAO, Hulong ZHANG, Hui DAI, Yuwei CHEN, Long SUN, Heng XU, Xingyun LI

“…Hyperspectral LiDAR (HSL) can obtain high precision and resolution spatial data along with the spectral information of the target, which can provide effective and multidimensional data for various research and application fields. However, differences in transmitting signal intensities of HSL at various wavelengths lead to variations in corresponding echo intensities, making it challenging to directly reconstruct accurate optical characteristics (reflectance spectral profile) of the target with echo intensities. …”

Determination of the Band Gap Energy of SnO₂ and ZnO Thin Films with Different Crystalline Qualities and Doping Levels by Cecilia Guillén

“…For the various applications, it is essential to accurately determine the band gap energy, as it controls the optical and electrical behavior of the material. However, there is no single method for its determination; rather, different approximations depend on the crystalline quality and the doping level because these modify the energy band structure of the semiconductor. …”

INFLUENCE OF METHODS OF AUGMENTATION OF THE ALVEOLAR PROCESS DURING TOOTH EXTRACTION OPERATION ON THE STABILITY OF DENTAL IMPLANTS by M.O. Kolisnychenko, K.P. Lokes

“…Patients were enrolled into three clinical groups depending on the method of alveolar process augmentation. Before the surgical stage of dental implantation, which corresponded to the 90th day after the tooth extraction operation, the lowest indicator of the optical density of bone tissue was noted in patients of the control group, where the healing of the socket of the removed tooth took place traditionally under a blood clot. …”

Improvement of modeling methods in rats with diabetic nephropathy and the expression level of IL-10 in kidney tissue by CAO Dong-dong, LI Niu, CAO Zi-yu, HOU Yu-long, NI Wen-juan, LENG Xiao-min, LIU Yun, SHI Jing-jing, Guo Ming-hao, MA Dong-hong

“…Objective To improve the modeling method in diabetic nephropathy rats,and to detect the expression of IL-10 in kidney tissue.Methods Forty-eight male SD rats were randomly classified as normal control group(NC group,n=24)and diabetes group(DM group,n=24).In the DM group intraperitoneal injection of STZ at a dose of 40 mg/kg was performed one time to induce a diabetes model.Blood sugar,urine sugar,urinary microalbumin,urinary creatinine levels were detected at 0,4,8,12 weeks after successfully modeling,respectively.At the same time, the kidney pathology of rats at different time points was observed,and IL-10 expression levels was detected with immunohistochemical method.Results Compared with NC group,the modeling success rate of rats in the DM group was 75%,and the modeled rats showed significantly increased drink,food uptake and urine.By 12 weeks the average weight of rats in the DM group was(478.0±79.1)g,significantly lower than that in NC group(650.0 ±26.9)g.Blood glucose in the DM group(25.6±5.3)mmol/L was significantly higher than that in the NC group(5.2±0.2)mmol/L.Until the end of the experiment,it was found that blood sugar was still maintained at(23.0±5.5)mmol/L.In the DM group rats,urine microalbumin creatinine ratios at 8 weeks and 12 weeks were(39.0 ±18.6)mg/g and(77.0±12.3)mg/g,respectively,significantly higher than those in the control group(15.1±5.4)mg/g,(15.8±7.0)mg/g).Optical microscope observation indicated that DM group rat experienced renal interstitium edema and inflammatory cell infiltration at 0 weeks,and mild thickening of the glomerular base membrane and renal tubular epithelial vacuolar degeneration at 12 weeks.The results of immunohistochemistry showed that the expression of IL-10 in NC group was higher than that in DM group.Conclusions When high sugar and high-fat combined with a small dose of STZ are used to establish a DKD model,at 12 weeks the kidney has mild thickening of renal glomerular base membrane,vacuolar degeneration of renal tubular epithelial cells and other pathological changes.However,Blood glucose ≥16.7 mmol/L in the tail vein ≥16.7 mmol/L cannot be used alone to judge success of the modeling of DKD.The decreased expression of IL-10 in renal tissues further demonstrates that IL-10 is involved in the pathogenesis of DKD and may be the target of DKD treatment.…”
