Protoplasts isolated from wild cotton Gossypium davidsonii were cultured in KM8P medium supplemented with different phytohormones. The most effective combination was 0.45 µM 2,4-dichlorophenoxyacetic acid, 2.68 µM α-naphthaleneacetic acid and 0.93 µM kinetin and the division percentage at the 8th day was 30.78 ± 3.04 %. The density of protoplasts at 2–10 ×(More)
Hypocotyls of cotton (Gossypium hirsutum L.) cultivars cv. YZ-1, Coker 312 and Coker 201 were inoculated on Murashige and Skoog callus induction medium. YZ-1 exhibited a very high regeneration potential, with 81.9 % of the explants inoculated differentiated into embryogenic callus within 8–10 weeks. During the process of callus maintenance (subculture for 1(More)
This article investigates whether market competition enhances the incentives of Chinese industrial firms to avoid corporate income tax. We estimate the effects of competition on the relationship between firms reported accounting profits and their imputed profits based on the national income account. To cope with measurement errors and potential endogeneity,(More)
Lipoxins (LXs) are endogenous antiinflammatory and pro-resolving eicosanoids generated during various inflammatory conditions. Recent research has revealed the novel immunomodulatory function of LXs. The aim of this study is to investigate whether LXs modulate the pathogenesis of collagen-induced arthritis (CIA), a typical chronic immune-mediated(More)
Novelty: Malignant peritoneal mesothelioma (MPM) is a rare disease confined to peritoneal cavities in most cases, seldom seen in intraand extra-abdominal invasion. In addition, MPM is easy of misdiagnosis and has a poor prognosis. Here, we report a case of colonic invasion induced by MPM in order to help prevent from misdiagnosis and prolong survival time.(More)
The paper considers studentized tests in time series regressions with nonparametrically autocorrelated errors. The studentization is based on robust standard errors with truncation lagM = bT for some constant b 2 (0; 1] and sample size T: It is shown that the nonstandard …xed-b limit distributions of such nonparametrically studentized tests provide more(More)
Three constructs harbouring novel Bacillus thuringiensis genes (Cry1C, Cry2A, Cry9C) and bar gene were transformed into four upland cotton cultivars, Ekangmian10, Emian22, Coker201 and YZ1 via Agrobacterium-mediated transformation. With the bar gene as a selectable marker, about 84.8 % of resistant calli have been confirmed positive by polymerase chain(More)
Introduction: Coherent phase modulated RF/photonic links have been proposed [1, 2] to realise high dynamic range analogue optical links, which require the use of an optical phase-locked loop (OPLL) as a linear phase demodulator. Through feedback, the OPLL forces the output phase response of a local optical phase modulator to mirror the phase of an incoming(More)
A new family of kernels is suggested for use in long run variance (LRV) estimation and robust regression testing. The kernels are constructed by taking powers of the Bartlett kernel and are intended to be used with no truncation (or bandwidth) parameter. As the power parameter ( ) increases, the kernels become very sharp at the origin and increasingly(More)
