In eusocial insect colonies, non-reproductive workers often perform different tasks. Tasks of an individual worker are shifted depending on various factors, e.g., age and colony demography. Although a vitellogenin (Vg) gene play regulatory roles in both reproductive and non-reproductive division of labours in a honeybee, it has been shown that the insect Vg underwent multiple gene duplications and sub-functionalisation, especially in apical ant lineages. The regulatory roles of duplicated Vgs were suggested to change evolutionarily among ants, whereas such roles in phylogenetically basal ants remain unclear. Here, we examined the expression patterns of conventional Vg (CVg), Vg-like A, Vg-like B and Vg-like C, as well as Vg receptor, during the task shift in an age-dependent manner and under experimental manipulation of colony demography in a primitive ant Diacamma sp. Expressions of CVg and Vg-like A in a brain were associated with a nursing task. It is suggested that associations of brain expressions of these Vgs with worker tasks were acquired in the basal ant lineage, and that such Vg functions could have sub-functionalised in the derived ant lineage. 相似文献

BackgroundTo evaluate the ability of peripheral blood inflammatory markers in predicating the typing of COVID‐19, prognosis, and some differences between COVID‐19 and influenza A patients.MethodsClinical data on 285 cases laboratory‐confirmed as SARS‐CoV‐2 infection were obtained from a Wuhan local hospital''s electronic medical records according to previously designed standardized data collection forms. Additional 446 Influenza A outpatients’ hematologic data were enrolled for comparison.ResultsNLR, SII, RLR, PLR, HsCRP, and IL‐6 were significant higher and LMR was lower in severe COVID‐19 patients than in mild COVID‐19 patients (p < .001). PLR and LMR were lower in the individuals with influenza A than those with COVID‐19 (p < .01). COVID‐19 patients with higher levels of NLR, SII, RLR, PLR, HsCRP, and IL‐6 and lower LMR were significantly associated with the severe type. AUC of NLR (0.76) was larger while the specificity of IL‐6 (86%) and sensitivity of HsCRP (89%) were higher than other inflammatory markers in predicating the typing of COVID‐19. PT had obvious correlation with all the inflammatory markers except RPR. NLR showed positive correlations with AST, TP, BUN, CREA, PT, and D‐dimer. Patients with high IL‐6 levels have a relatively worse prognosis (HR = 2.30).ConclusionPeripheral blood inflammatory markers reflected the intensity of inflammation and associated with severity of COVID‐19.NLR was more useful to predict severity as well as IL‐6 to predict prognosis of COVID‐19. PLR and LMR were initially found to be higher in SARS‐CoV‐2 virus‐infected group than in influenza A. 相似文献

ObjectiveWe aimed to establish an objective neurophysiological test protocol that can be used to assess the somatosensory nervous system.MethodsIn order to assess most fiber subtypes of the somatosensory nervous system, repetitive stimuli of seven different modalities (touch, vibration, pinprick, cold, contact heat, laser, and warmth) were synchronized with the electroencephalogram (EEG) and applied on the cheek and dorsum of the hand and dorsum of the foot in 21 healthy subjects and three polyneuropathy (PNP) patients. Latencies and amplitudes of the modalities were assessed and compared. Patients received quantitative sensory testing (QST) as reference.ResultsWe found reproducible evoked potentials recordings for touch, vibration, pinprick, contact-heat, and laser stimuli. The recording of warm-evoked potentials was challenging in young healthy subjects and not applicable in patients. Latencies were shortest within Aβ-fiber-mediated signals and longest within C-fibers. The test protocol detected function loss within the Aβ-fiber and Aδ-fiber-range in PNP patients. This function loss corresponded with QST findings.ConclusionIn this pilot study, we developed a neurophysiological test protocol that can specifically assess most of the somatosensory modalities. Despite technical challenges, initial patient data appear promising regarding a possible future clinical application.SignificanceEstablished and custom-made stimulators were combined to assess different fiber subtypes of the somatosensory nervous system using modality-specific evoked potentials. 相似文献

目的 探讨乳腺原发癌和相应淋巴结转移癌中乙醛脱氢酶1(ALDH1A1)和转化生长因子-β1(TGF-β1)的表达情况及与患者预后的相关性,并探讨ALDH1A1与TGF-β1之间的相关性。方法 收集有淋巴结转移的乳腺非特殊型浸润性癌197例,采用免疫组化方法检测ALDH1A1和TGF-β1在原发癌及相应淋巴结转移癌中的表达情况,并对临床病理参数及预后进行统计学分析。结果 ALDH1A1和TGF-β1在乳腺原发癌和相应淋巴结转移癌中表达的一致率分别为87.82%和86.80%,两者呈明显的正相关(P<0.05);Kaplan-Meier生存曲线结合Log-rank检验显示,在原发癌和淋巴结转移癌中,ALDH1A1和TGF-β1均为不良预后因素(P<0.05);单因素Cox比例风险回归模型分析显示,组织学分级、肿块大小、阳性淋巴结个数、原发癌和转移癌中ALDH1A1和TGF-β1均是患者预后的危险因素(P<0.05),多因素分析结果显示原发癌ALDH1A1、转移癌TGF-β1及阳性淋巴结个数是患者预后的独立危险因素(P<0.05);Spearman相关性分析显示,在乳腺原发癌和相应淋巴结转移癌中,ALDH1A1和TGF-β1均呈明显正相关(P<0.05)。结论 ALDH1A1和TGF-β1的表达在原发癌和相应淋巴结转移癌中呈正相关,且均与预后相关。ALDH1A1和TGF-β1的表达存在正相关,原发癌ALDH1A1和转移癌TGF-β1是判断乳腺癌预后的独立影响因素。 相似文献

目的 研究不同照射方式下核黄素-A波紫外线兔巩膜胶原交联术对兔巩膜成纤维细胞生物力学特性的影响。方法 取健康新西兰大白兔24只,随机将兔平均分为A、B两组,每组选取左眼为实验眼,右眼为对照眼。麻醉后暴露左眼鼻上方巩膜。在该处巩膜滴加5-磷酸核黄素5 min后,用波长为370 nm的紫外线灯照射。A组的照射时间为30 min,能量密度为3.0 mW·cm-2;B组的照射时间为9 min,能量密度为10.0 mW·cm-2。照射期间,每2 min滴加1次5-磷酸核黄素溶液,以保持巩膜的湿润。术后60 d,处死实验兔,培养实验眼交联部位及对照眼相应部位的巩膜成纤维细胞,用细胞微管吸吮实验检测巩膜成纤维细胞的杨氏模量、表观黏性。结果 A、B两组实验眼巩膜细胞的杨氏模量、表观黏性均较各自对照眼显著增强,差异均有统计学意义(均为P<0.05);而A、B两组实验眼间、及对照眼间巩膜细胞的杨氏模量、表观黏性差异无统计学意义(均为P>0.05)。以上结果表明,交联术后巩膜细胞的黏弹性发生了明显的变化,黏弹性显著升高。而两种照射方式之间巩膜细胞的黏弹性无显著差异。结论 两种不同的照射方式,均能使巩膜成纤维细胞的生物力学性能发生显著增强,而两种照射方式之间并未见明显的差别。 相似文献
