The membrane lipids from fast-elongating wild-type cotton （Gossypium hirsutum） fibers at 10 days post- anthesis, wild-type ovules with fiber cells removed, and ovules from the fuzzless-lintless mutant harvested at the same age, were extracted, separated, and quantified. Fiber cells contained significantly higher amounts of phosphatidylinositol （PI） than both ovule samples with PI 34：3 being the most predominant spe- cies. The genes encoding fatty acid desaturases （415GhFAD）, PI synthase （PIS） and PI kinase （PIK） were expressed in a fiber-preferential manner. Further analysis of phosphatidylinositol monophosphate （PIP） indicated that elongating fibers contained four- to five-fold higher amounts of PIP 34：3 than the ovules. Exog- enously applied linolenic acid （C18：3）, soybean L-α-PI, and PIPs containing PIP 34：3 promoted significant fiber growth, whereas a liver PI lacking the C18：3 moiety, linoleic acid, and PIP 36：2 were completely ineffec- tive. The growth inhibitory effects of carbenoxolone, 5-hydroxytryptamine, and wortmannin were reverted by C18：3, PI, or PIP, respectively, suggesting that PIP signaling is essential for fiber cell growth. Furthermore, cotton plants expressing virus-induced gene-silencing constructs that specifically suppressed Gh15FAD, GhPIS, or GhPIK expression, resulted in significantly short-fibered phenotypes. Our data provide the basis for in-depth studies on the roles of PI and PIP in mediating cotton fiber growth.

OBJECTIVE To evaluate core needle biopsy (CNB) as a mini-mally invasive method to examine breast lesions and discuss theclinical significance of subsequent immunohistochemistry (IHC)*** The clinical data and pathological results of 235 pa-tients with breast lesions, who received CNB before surgery, wereanalyzed and compared. Based on the results of CNB done beforesurgery, 87 out of 204 patients diagnosed as invasive carcinomawere subjected to immunodetection for p53, c-erbB-2, ER and *** morphological change of cancer tissues in response to chemo-therapy was also *** In total of 235 cases receiving CNB examination, 204were diagnosed as invasive carcinoma, reaching a 100% consistentrate with the surgical diagnosis. Sixty percent of the cases diag-nosed as non-invasive carcinoma by CNB was identified to havethe presence of invading elements in surgical specimens, and simi-larly, 50% of the cases diagnosed as atypical ductal hyperplasia byCNB was confirmed to be carcinoma by the subsequent result ofexcision biopsy. There was no significant difference between theCNB biopsy and regular surgical samples in positive rate of im-munohistochemistry analysis (p53, c-erbB-2, ER and PR; P >0.05).However, there was significant difference in the expression rate ofp53 and c-erbB-2 between the cases with and without morphologi-cal change in response to chemotherapy (P < 0.05). In most caseswith p53 and c-erbB-2 positive, there was no obvious morphologi-cal change after *** CNB is a cost-effective diagnostic method withminimal invasion for breast lesions, although it still has some limi-tations. Immunodetection on CNB tissue is expected to have greatsignificance in clinical applications.

The 40Ar/39Ar ages indicate that the eclogite facies rocks of the Hasiate slice in the western Tianshan Mountains were formed at the early stage of Devonian （401 Ma） and had been uplifted to the greenschist facies tectonic level in the middle stage of Devonian （381 Ma）. The formation and uplift of the blueschists of the Akesayi slice are constrained to the late stage of Devonian （370-364 Ma）. The different tectonic slices in the high-pressure metamorphic belt have experienced the different uplift history.

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.

航向角误差随时间累积是采用惯性技术实现行人定位系统中影响导航精度的主要因素。通过典型建筑结构和行人行走特征的分析,提出一种室内行人导航航向反馈修正算法。根据行人是否在主方向上直行,区分在两种直行情况下的航向反馈条件,构建航向差值作为状态量进行自适应无迹卡尔曼滤波(AUKF),并运用反馈航向值参与四元数解算,从而减少航向误差的累积。嵌入式消防单兵定位系统平台的实验验证表明:提出的航向反馈修正算法与不反馈时相比,能够精确解算航向的时间增加两倍以上,且导航误差在1%以内,适应环境能力也较强。
