Ambient temperature plays a large role in insect growth, development and even their distribution. The elucidation of the associated molecular mechanism that underlies the effect of constant high temperature will enables us to further understand the stress responses. We constructed four digital gene expression libraries from the fat body of female and male(More)
Motion control of gun barrels is an ongoing topic for the development of gun control equipments possessing excellent performances. In this paper, a typical fractional order PID control strategy is employed for the gun control system. To obtain optimal parameters of the controller, a multiobjective optimization scheme is developed from the loop-shaping(More)
Elevated extracellular free fatty acids (FFAs) can induce pancreatic beta cell apoptosis, thereby contributing to the pathogenesis of type 2 diabetes mellitus (T2D). Mitochondrial dysfunction has been implicated in FFA-induced beta cell apoptosis. However, molecular mechanisms linking mitochondrial dysfunction and FFA-induced beta cell apoptosis are not(More)
Environmental exposure to lead during developmental stages has been established as a potential cause of intellectual deficits. The high susceptibility of rapidly developing fetal and infant brains to external factors suggests that impairment of later cognitive functions may arise from relatively minor prenatal exposure to environmental lead levels. In this(More)
Chronic exposure to free fatty acids (FFAs) may induce β cell apoptosis in type 2 diabetes. However, the precise mechanism by which FFAs trigger β cell apoptosis is still unclear. Tribbles homolog 3 (TRB3) is a pseudokinase inhibiting Akt, a key mediator of insulin signaling, and contributes to insulin resistance in insulin target tissues. This paper(More)
The glycosylation of UDP-glucosyltransferases (UGTs) is of great importance in the control and elimination of both endogenous and exogenous toxins. Bm-UGT10286 (UGT86) is the sole provider of UGT activity against the 5-O position of quercetin and directly influences the formation of green pigment in the Bombyx cocoon. To evaluate whether cocoon coloration(More)
Umbelliferones have gained significant attention due to their tumor-inhibitory effects in vitro. This study was undertaken to examine the impact of umbelliferones in an invertebrate model organism, Bombyx mori, to assess the underlying antimicrobial activities via antioxidation in vivo. Oral administration of 4 mM 4-methylumbelliferone (4-MU), a model(More)
Chitin synthase is the key regulatory enzyme for chitin synthesis and excretion in insects, as well as a specific target of insecticides. The chitin synthase A gene (BmChsA) cloned from Bombyx mori, the model species of lepidopteran, is an epidermis-specific expressed gene during the molting stage. Knockdown BmChsA gene in 3rd instar larvae increased the(More)
The silk gland of Bombyx mori (BmSG) has gained significant attention by dint of superior synthesis and secretion of proteins. However, the application of BmSG bioreactor is still a controversial issue because of low yields of recombinant proteins. Here, a 3057 bp full-length coding sequence of Hpl was designed and transformed into the silkworm genome, and(More)
Organic molecules and polymers with extended π-conjugation are appealing as advanced electronic materials, and have already found practical applications in thin-film transistors, light emitting diodes, and chemical sensors. Transition metal (TM)-catalyzed cross-coupling methodologies have evolved over the past four decades into one of the most powerful and(More)
