The self-thinning rule defines a straight upper boundary line on log-log scales for all possible combinations of mean individual biomass and density in plant populations. Recently, the traditional slope of the upper boundary line, -3/2, has been challenged by -4/3 which is deduced from some new mechanical theories, like the metabolic theory. More experimental or field studies should be carried out to identify the more accurate self-thinning exponent. But it＇s hard to obtain the accurate self-thinning exponent by fitting to data points directly because of the intrinsic problem of subjectivity in data selection. The virtual dynamic thinning line is derived from the competition-density （C-D） effect as the initial density tends to be positive infinity, avoiding the data selection process. The purpose of this study was to study the relationship between the virtual dynamic thinning line and the upper boundary line in simulated plant stands. Our research showed that the upper boundary line and the virtual dynamic thinning line were both straight lines on log-log scales. The slopes were almost the same value with only a very little difference of 0.059, and the intercept of the upper boundary line was a little larger than that of the virtual dynamic thinning line. As initial size and spatial distribution patterns became more uniform, the virtual dynamic thinning line was more similar to the upper boundary line. This implies that, given appropriate parameters, the virtual dynamic thinning line may be used as the upper boundary line in simulated plant stands.

Background Connexin43 （Cx43） is the predominant gap junction protein in heart and is involved in the control of cell-to-cell communication to modulate the contractility and the electrical coupling of cardiac myocytes. Left ventricular （LV） hypertrophy is accompanied by changes of Cx43 expression. Recent studies have demonstrated that statins reduced cardiac hypertrophy. However, it is unknown whether statins can affect Cx43 expression in hypertrophied left ventricular myocardium. This study was designed to assess the effects of atorvastatin on LV hypertrophy and Cx43 expression in spontaneously hypertensive rats （SHR）. Methods Nine-week old SHRs were randomly divided into two groups. Some received atorvastatin at 30 mg/kg by oral gavage once daily for 8 weeks （SHR-A）; others received vehicle. Age-matched Wistar-Kyoto rats （WKY） received atorvastatin or vehicle for 8 weeks were used as controls. At the end of the experiment, we investigated LV hypertrophy and the expression of Cx43 in LV myocardium in four groups. Cx43 expression was investigated by the methods of Western blotting, immunohistochemistry, and transmission electron microscope. LV hypertrophy was accessed by pathological analysis and plasma brain natriuretic peptide （BNP） level. Results LV hypertrophy was prominent in untreated SHR. In SHR, LV myocardium Cx43 level was upregulated, and the distribution of Cx43 was displaced from their usual locations to other sites at various distances away from the intercalated disks. After atorvastatin treatment, myocardium Cx43 level was reduced in SHR-A, and the distribution of Cx43 gap junction became much regular and confined to intercalated disk. Statins also prevented LV hypertrophy in SHR. Conclusions These results provide novel in vivo evidence for the key role of Cx43 gap junctions in LV hypertrophy and the possible mechanism in anti-hypertrophic effect of statins. Atorvastatin treatment may have beneficial effects on LV hypertrophy in spontaneously hypertensi

Sequence-activated chemiluminescence(CL) technique offers a unique approach to detecting specific biomolecules or cellular events with high sensitivity and spatial resolution. The fundamental principle behind sequence-activated CL probes involves tailoring highly-controllable CL signals in response to specific sequences or events of interest, thus enabling high-contrast signals under complex physiological conditions. This sequential activation could be triggered by enzymes, reactive oxygen species(ROS), biothiols or changes in the microenvironment. These unique sequence-activated CL probes bestow several advantages, including minimal background, deep-tissue penetration, and the ability of non-invasive or minimally invasive detection. The sequence-activated CL techniques represent a significant advancement in molecular imaging and diagnostics. In this mini-review, we focus on the latest developments in sequential CL probes, addressing the technical challenges and discussing the future trajectory by harnessing CL signaling and molecular recognition.

态度改变过程与思想政治教育过程具有类似性,我们可以运用态度改变理论来诊断大学生思想政治教育中存在的问题。在态度改变理论视阈下,思想政治教育存在以下问题:教育内容的重复性,教育过程的单向性,教育方式的外在性。解决思想政治教育中存在问题的对策:提高教育内容的层次性,实现重复性与新颖性相统一;增强教育过程的对话性,实现主导性与批判性相统一;突显教育价值的本体性,实现引导性与自主性的统一。
