Promoter trapping in Magnaporthe grisea   总被引:1,自引:0,他引:1  
INTRODUCTION Magnaporthe grisea is a filamentous ascomy- cete that parasitizes economically important crops, such as barley, wheat, and rice (Talbot, 2003). It is also a good experimental model for studying fungal pathogenesis by both classical and molecular genetics (Dean, 1997). In recent years, many techniques have been developed to identify functional genes in M. grisea (Kamakura et al., 1999; Rauyaree et al., 2001; Takano et al., 2003; Irie et al., 2003; Lu et al., 2005). Of these…  相似文献

Restaurant emissions removal by a biofilter with immobilized bacteria   总被引:2,自引:0,他引:2  
INTRODUCTION Restaurant emission is a pollutant to atmosphereand human body. Polycyclic aromatic hydrocarboncontained in oil smoke directly induces lung andbladder cancer (Chen and Ye, 1991; Gupta et al.,2001; Lutz, 1982). According to former researches(Kleinerman et al., 1999; Liu et al., 1987), oil smokecontains many harmful substances that can induce notonly general diseases but also gene mutation, DNAdamage and immune function impairment, and manyingredients such as fatty ac…  相似文献

Poisoning is often characterized by the acute onset,rapid progress,or specific manifestations of pathological symptoms,such as pulmonary fibrosis due to paraquat poisoning or high mortality arising from dinitrophenol intoxication (Jiang et al.,2016;Wang et al.,2017;Feng et al.,2018;Lu,2018;Xu and Lu,2019).Unlike general poisoning,however,the manifestation of n-hexane intoxication is subacute,and its clinical symptoms are dormant,and thus the provision of a timely and correct diagnosis is often difficult.  相似文献

INTRODUCTION Homoharringtonine (HHT) is a cephalotoxin alkaloid with anti-leukemic activity and had been used successfully in the treatment of acute and chronic myeloid leukemias (O払rien et al., 1995; 1999; Feldman et al., 1992). The principal mecha-nism of action by HHT is the inhibition of protein synthesis in a dose- and time-dependent manner by binding to ribosome and inhibiting polypeptide chain elongation (Tujebajeva et al., 1989; Zhou et al., 1995). HHT had been shown to indu…  相似文献

INTRODUCTION Green gram (Vigna radiata) is an important short duration pulse crop. Due to its high nutritive value, it is grown throughout the tropical countries of South and Southeast Asia, particularly in India (Vavilov, 1951). Among various pests and diseases, nematodes-fungus disease complex particularly of Meloidogyne incognita and Fusarium oxysporum poses a great problem to the cultivation of pulse crops by inflicting severe yield losses (Perveen et al., 1999; De et al., 2000; …  相似文献

INTRODUCTION Gemcitabine (2′,2′-difluorodeoxycytidine) is asynthetic pyrimidine nucleoside analogue with cyto-toxic activity in non-small-cell lung cancer (NSCLC)(Anderson et al., 1994; Abratt et al., 1994; Lund et al.,1994). Gemcitabine is a prodrug which, through de-oxycytidine kinase and other nucleotide kinases, ex-erts its cytotoxic effects through its active intracellu-lar metabolites, gemcitabine diphosphate andtriphosphate (Guchelaar et al., 1996;…  相似文献

INTRODUCTION Lipase (EC 3.1.1.3) is an important hydrolysis enzyme (Jaeger et al., 1994) excreted to the envi-ronment by plant roots and microorganisms. Many pollutants such as organophosphorus pesticides and synthetic polyesters and polyamides can be degraded by lipase (Monroy-Noyola et al., 1999; Marten et al., 2003). In soil, enzymatic reactions occur in a het-erogeneous rather than homogeneous environment (Huang et al., 1998). Catalytic function of lipase, an extracelluar enzyme, …  相似文献

正Staphylococcal enterotoxin A (SEA) synthesized by Staphylococcus aureus is a foodborne and heatstable toxin, which is a great threat to human health (Pexara et al., 2010). Highly sensitive antibodies are a key factor in the immunological detection of SEA,which is one of the most effective ways to detect SEA because of its accuracy, agility, and efficiency (Nouri et al., 2018).  相似文献

INTRODUCTION Piezoelectric symmetric structures always play an important role in the use of piezoelectric materials (Olesiak and Pyryev, 1995; Ding et al., 2003; Wu et al., 2003). To improve the durability of this kind of piezoelectric structures, functionally gradient piezo- electric materials (FGPM) have been developed and used to produce these devices such as sensors and actuators (Hauke et al., 2000; Zhu et al., 1995). For the case when a rectangular plate made of function- ally gr…  相似文献

INTRODUCTION Barley (Hordeum vulgare L.) is widely used as food and feed, but its most economically important use is for malting and brewing. Many barley charac- ters are involved in malt quality, of which protein content is the most important, as it has been observed to be related to malt qualities, such as extract and diastatic power (Weston et al., 1993; Eagles et al., 1995).Barley suitable for malting should have low grain protein content, as high protein content will not only reduce…  相似文献

BRAIN NATRIURETIC PEPTIDE Several studies demonstrated that the heart is an endocrine organ (Henry and Pearce, 1956; Kisch, 1956; de Bold, 1985; de Bold et al., 1981; 1996; 2001). Atrial natriuretic peptide (ANP) was the first cardiac hormone identified in 1984 (Kangawa et al., 1984; de Bold et al., 1981). Later on, a new com- pound from pig brain was found, which had similar natriuretic and diuretic effects as ANP (Sudoh et al., 1988). This peptide was named brain (B-type) natr…  相似文献
