Male DBA/2J mice are approximately 20-fold more susceptible than male C57BL/6J mice to hepatocarcinogenesis induced by perinatal treatment with N,N-diethylnitrosamine (DEN). In order to elucidate the genetic control of hepatocarcinogenesis in DBA/2J mice, male BXD recombinant inbred, D2B6F1 x B6 backcross, and D2B6F2 intercross mice were treated at 12 days of age with DEN and liver tumors were ...

dentin bonding agents (dba) have been used as root-end filling materials. present study evaluated the effects of polymerized dba on secretion of pro-inflammatory cytokines by normal human monocytes. in this study, monocytes were directly isolated from human peripheral blood, and exposed to cured scotch bond 1 (single bond) and prime and bond for 36 and 72 hours. secretion of il-1β and tnf-α in ...

Purpose: Photon counting (PC) computed tomography (CT) can provide material selective CT imaging at lowest patient dose but it suffers from suboptimal count rate. A dynamic beam attenuator (DBA) can help with count rate by modulating x-ray beam intensity such that the low attenuating areas of the patient receive lower exposure, and detector behind these areas is not overexposed. However, DBA ma...

Normal-hearing subjects show improved speech understanding when they wear conventional passive hearing protectors in noisy surroundings. In contrast, hearing-impaired subjects are at a disadvantage. Sound attenuation exacerbates the handicap from hearing loss (Abel et al., 1982). Level-dependent (active) hearing protectors which provide limited amplification of sounds below 85 dBA have the oppo...

Fiber wireless access (FiWi) network is a category of hybrid network, which cumulates the advantages of optical network and wireless network at frontend and backend respectively. FiWi is one of those networks which are capable of providing high bandwidth as well as great flexibility. In today’s world of high speed applications demand of spectrum is increasing rapidly, hence it becomes criticall...

Environmental noise has reached an alarming level and is affecting the exposed population. The levels are elevated during festival season. This study aims to explore influence of prime festivals on in urban area. 18 locations Raipur city Chhattisgarh, India, were selected for conducting Ganesh Utsav, Dussehra, Diwali festivals. Study equivalent (Leq) other parameters Traffic index (TNI), Noise ...

Murine typhus rickettsiae injected intraperitoneally in mice of the dba strain caused a uniformly fatal rickettsial peritonitis if the animals were kept at a room temperature ranging from 65-73 degrees F. or from 70-80 degrees F. With an environmental temperature range of 85-98 degrees F., a mortality of less than 25 per cent was observed. By utilizing different strains of mice and controlling ...

Diamond-Blackfan anemia (DBA; OMIM:105650) attracts much attention, because symptoms are associated with mutations in RPS19 and RPS24 in 25% and 2% of DBA patients, respectively, indicating a possible relationship between the ribosomal function, translation levels and erythropoiesis. Indeed, in our recent study we showed that translational efficiency was lowered in most DBA patients, and leucin...

The behavioural and electrocortical effects of two monobactam derivatives were studied after intraperitoneal (ip) administration in DBA/2 mice, a strain genetically susceptible to sound-induced seizures, and in C57 and Swiss mice, two strains not prone to seizure. DBA/2 mice were more susceptible than Swiss and C57 mice to seizures induced by aztreonam or carumonam. No significant differences w...
