Mild traumatic brain injury (mTBI) causes postural control deficits and accordingly comparison of aberrant postural control against normal postural control may help diagnose mTBI. However, in the current literature, little is known regarding the normal pattern of postural control in young children. This study was therefore conducted as an effort to fill this knowledge gap. Eight normal school-aged children participated. Posture assessment was conducted before (7-8 a.m. in the morning) and after (4-7 p.m. in the after-noon) school on regular school days using the Balance Master? evaluation system composed of 3 static tests and 2 dynamic balance tests. A significant difference in the weight-bearing squats was detected between morning hours and afternoon hours (P ly on the left side with the knee fully extended and at various degrees of knee flexion. A significantly better directional control of the lateral rhythmic weight shifts was observed at the end of the afternoon than at morning hours (P lts from previous studies in adults, sug-gesting age-related differences in posture control in humans. On a regular school day, the capacity of postural control and laterality or medio-lateral balance in children varies between morning and afternoon hours. We suggest that posturographic assessment in children, either in normal (e.g., physical education and sports training) or in abnormal conditions (e.g., mTBI-associated balance disorders), be better performed late in the afternoon.

The cytotoxic effect of extract of camellia ptilophyllachang(ECPC) and extract of camellia sinensis(ECS) onHela cell line, poorly differentiated nasopharyngealcarcinoma cell line(CNE2) and gastric cancer cell line(MGC-803 ) in vitro was studied using MIT assay *** results showed that ECPC and ECS possessed significantcytotoxic effect on above three cell lines. The anticancer testin mice showed that ECPC had marked inhibitory effectagainst Ehrlich solid carcinoma(ESC) with inhibition ratesof 17. 8 48. 3% and with inhibition rates of 28. 3-54. 5% against reticular cell sarcoma(l2), and that ECShad inhibition rates of 31 . 5 -49. 4 % against ESC and 35. 8- 50% against l2. These two extracts had only marginalinhibitory effect against sarcoma- 180. The unknottingactivity of DNA topoisomerase II was inhibited completelyby ECPC and ECS at the concentration of 50 μg/ mlsuggesting that DNA topoisomerase II might be a targetenzyme of these two extracts.

本试验采用不同基因型玉米自交系和杂交种对玉米单叶水分利用效率（WUE）的研究表明以下5点。（1）高水分利用效率的玉米基因型其光合速率（PH），蒸腾速率（TR）也较高，而气孔阻力（RS）较低。WUE与PH，TR和RS存在显著的线性关系，YWUE＝2．3613＋0．051SXPH＝0．1093XTR＝0．399ZXRS，R＝0．934。逐步回归的结果，也可用PH预测WUE，YWUE＝0．7211＋0041SXPH，R＝0．897.（2）直立、平展、中间三类株型玉米基因型间的WUE差异不显著。（3）随着叶片的衰老，玉米叶片的RS值显著增高，而PH较TR下降的更快，因此WUE逐渐降低。（4）WUE与RS在本试验各种条件下多表现为弱的负相关，进一步证实提高WUE应首先从提高单叶PH入手。（5）叶片叶绿素含量可作为鉴定、筛选玉米WUE品种资源及高WUE育种的参考指标。

Hydric properties evolution during drying differs from one product to another and has been the subject of various studies due to its crucial importance in modeling the drying process. The variation of these parameters in the solid matrix and in time during the drying of Spirulina platensis has not known an advanced understanding. The objective of this study was to evaluate the evolution of the water content profile, the mass flow, the concentration gradient and the diffusion coefficient during the drying of Spirulina platensis taking into account the shrinkage. Modeling and experimental analysis (at 50°C and HR = 6%) by the cutting method a cylinder 20 mm in diameter and 40 mm thick were carried. The water content profiles of two different products grown in semi-industrial farms from Burkina Faso and France with initial water contents respectively of the range from 2.73 kgw/kgdb and 3.12 kgw/kgdb were determined. These profiles have been adjusted by a polynomial function. Identical water behavior is observed regardless of the origin of the samples. Water distribution is heterogeneous. Mass flow and concentration gradient are greater at the edge than inside the product. The water transport coefficient, ranging from 1.70 × 10?10 to 94 × 10?10 m2/s, is determined from a linear approach.

Background:Given that epidemiological evidence suggests a potential protective role for Bacille-Calmette-Guerin against COVID-19,we aimed to explore whether pre-exposure of human monocyte-derived macrophages and dendritic cells to BCG could modulate their response to SARS-CoV-2 ***:Dual THP-1 cells containing 2 reporter plasmids for transcription factors NF-κB,and IRF were differ-entiated into macrophages over 3 days using phorbol 12-myristate 13-acetate,or into dendritic cells over 6 days using commercial monocyte-dencritic cell differentiation media and matured with recombinant tumor necrosis factor-α.Cells were exposed to BCG for 24 h and then stimulated with SARS-CoV-2 S-glycoprotein for 24 ***:Pre-exposure of human macrophages and DCs to BCG increased IRF and NF-kb activation in response to the SARS-CoV-2 ***:Our results showed that pre-exposure of both types of cells to BCG exhibited an increase in inflam-matory transcription factors upon stimulation with ***-induced trained immunity may be an important tool for reducing susceptibility to SARS-CoV-2 infection and severity of *** findings help in the design of future BCG-based therapeutic approaches in the treatment of diseases caused by viral infections.
