AIM To explore factors associated with persistent hepatitis B virus (HBV) infection in a cohort of hepatocellular carcinoma (HCC)-affected families and then investigate factors that correlate with individual viral load among hepatitis B surface antigen (HBsAg)-positive relatives. METHODS questionnaire. Demographics, relationship to index case, HBsAg status of mothers and index cases were evaluated for association with the HBV persistent infection or viral load by generalized estimating equation analysis. RESULTS Among 729 relatives enrolled, parent generation (P = 0.0076), index generation (P = 0.0044), mothers positive for HBsAg (P = 0.0007), and HBsAg-positive index cases (P = 5.98 x 10(-8)) were associated with persistent HBV infection. Factors associated with HBV viral load were evaluated among 303 HBsAg-positive relatives. Parent generation (P = 0.0359) and sex (P = 0.0007) were independent factors associated with HBV viral load. The intra-family HBV viral load was evaluated in families clustered with HBsAg-positive siblings. An intra-family trend of similar HBV viral load was found for 27 of 46 (58.7%) families. Male offspring of HBsAg-positive mothers (P = 0.024) and older siblings were associated with high viral load. CONCLUSION Sex and generation play important roles on HBV viral load. Maternal birth age and nutritional changes could be the reasons of viral load difference between generations.

Electromagnetic interference (EMI) shielding inhigh-frequency range, especially the rapidly growing terahertz(THz) frequency range, attracts increasing attention due tothe potential application of terahertz in 6G wirelesscommunication, and security inspection. However, traditionalconductive EMI films typically achieve high shieldingeffectiveness through strong reflection, which may causesecondary pollution to other devices. Here, a gradientstructure strategy was proposed to constructTi_(3)C_(2)Tx/hydroxypropyl methyl cellulose (HPMC) film, in whichthe content of Ti_(3)C_(2)Tx gradually increases along the thicknessdirection, resulting in different conductivity of the two surfaces(surface-M and surface-H) for the film. The obtained gradientfilmexhibits an EMI shielding efficiency of over 48.5 dB in theTHz range (0.2-1.6 THz) at a thickness of 40 μm. Especially,as the THz waves incident from the surface-H to the film, the absorption effectiveness reaches 48.2 dB (average absorbedpower loss up to 91.4%), and the reflection effectiveness is only 0.3 dB. In additions, the gradient-film also demonstrates ahigh absorption rate of 95.5% in the infrared band (2.5-16.7 μm). Moreover, the gradient-film exhibits an excellent tensilestress and Young’s modulus value of 173.1 MPa and 2.8 GPa, respectively. Therefore, the gradient-film proposed in thiswork, with excellent electromagnetic absorption in both THz and infrared band, provides a promising candidate for the nextgenerationEMI shielding applications.

作者： Tao Zhou lin Li National Key Laboratory of Crop Genetic Improvement Huazhong Agricultural University HuBei HongShan Laboratory

The dual challenges of global climate change and population growth have increased demand for higher crop yields per unit area. The innovative technology of smart agriculture aims to synergize breeding, cultivation, and production through the application of biological and informatics technologies. Historically, the “Green Revolution” introduced semidwarf varieties of certain key crops by utilizing mutations affecting gibberellin pathways, which significantly increased planting densities and yields.

Background:T helper(Th)cell cytokines modulate inflammation and play a role in biliary atresia(BA).The aim of the study is a cross-sectional assessment of the levels of Th cytokines in the jaundice-free post Kasai procedure ***:There were 40 jaundice-free patients with BA and 28 normal controls *** were divided into 3 groups,including normal liver function,impaired liver function,and portal *** concentration of Th1[interferon-γ(INF-γ),interleukin(IL)-2],Th2(IL-4,IL-10),Th3[transforming growth factor-β1(TGF-β1)],Th17(IL-17)cytokines,and stromal cell-derived factor-1α(SDF-1α)were ***:The IFN-γ level was significantly higher in the BA patients with impaired liver function and portal hypertension than controls(P<0.0001 andP<0.0001,respectively).There was a signifi cantly increase of TGF-β1 in all BA groups compared with controls(P=0.003).The reduction of SDF-1αexpression was found in BA groups(P<0.0001).IL-10 levels significantly correlated with aspartate aminotransferase to platelet ratio index(r=0.496,P=0.001).For the cytokine correlations,there were no correlations of Th1,Th2 and Th17 cytokine with the other measured cytokines,but TGF-β1 was negatively correlated with SDF-1αlevels(r=-0.327,P=0.039).Conclusions:IFN-γand IL-10 are likely to be involved in the disease progression in ***,TGF-β1 is found to be a suppression marker associated with SDF-1αlevels and reduced production of TGF-β1 may be associated with the disease progression.
