Somatic embryogenesis (SE), by which somatic cells of higher plants can dedifferentiate and reorganize into new plants, is a notable illustration of cell totipotency. However, the precise molecular mechanisms regulating SE remain unclear. To characterize the molecular events of this unique process, transcriptome analysis, in combination with biochemical and(More)
The preparation of neem oil microemulsion and its acaricidal activity in vitro was developed in this study. In these systems, the mixture of Tween-80 and the sodium dodecyl benzene sulfonate (SDBS) (4:1, by weight) was used as compound surfactant; the mixture of compound surfactant and hexyl alcohol (4:1, by weight) was used as emulsifier system; the(More)
As a product of asexual reproduction in plants, the somatic embryo (SE) differentiates into a new plantlet via a zygotic embryogenesis-like process. Here, we present the phenotypic and cellular differences between SEs and zygotic embryos (ZEs) revealed by histological section scanning using three parallel development stages of the two types of embryos of(More)
A bacterium capable of methanethiol (MT) degradation was enriched and isolated by employing activated sewage sludge as the inoculum in a mineral medium containing MT. The isolate was identified as Paenibacillus polymyxa CZ05 through a Biolog test and 16S rDNA sequencing. This strain can utilize both organic and inorganic media and thrives at pH 4 to 9. The(More)
Neem (Azadirachta indica), popularly known as traditional medicine is a native plant in India. Neem oil is a vegetable oil derived from seeds or fruits of the neem tree through pressing or solvent extraction, and largely used in popular medicine to have antifungal, antibacterial, antimalarial, antiparasitic, anti-inflammatory, as well as immunemodulatory(More)
The combined subchronic effects of exposure to lead acetate and cadmium chloride on apoptosis protein expression were detected in the liver and kidney of rats to investigate the hazards of environmentally relevant, low-dose exposure to these compounds. The TUNEL assay showed that there were increased numbers of apoptotic cells. Immunohistochemical tests(More)
This study aims to investigate the effects of low-dose subchronic exposure to lead acetate (Pb(NO₃)₂) and cadmium chloride (CdCl₂·2.5H₂O) on bone in rats. The rats were assigned randomly to a control group and three experimental groups that were given the mixture of Pb(NO₃)₂ and CdCl₂·2.5H₂O by gastric gavage at doses of 0 mg/kg body weight (b.w.) (Group I,(More)
Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease associated with a high rate of mortality, characterised by an accumulation of fibroblasts/myofibroblasts in the fibroblastic foci (FF) and by an excessive deposition of extracellular matrix (ECM) in the lung parenchyma. The pathogenesis of this fatal disorder remains unclear. Previous evidence(More)
This study aimed to determine the effects of administering a mixture of subchronic lead acetate (Pb (NO3)2) and cadmium chloride (CdCl2·2.5H2O) on the bone metabolism of rats. A control group and three experimental groups consisted of randomly selected rats. Rats in each experimental group were orally administered with a mixture of Pb (NO3)2 and(More)
