The brain stem is necessary for the expression of behavioral reactions to noxious visceral inputs. Neurons in raphe magnus (RM) and the adjacent nucleus reticularis magnocellularis (NRMC) respond to visceral stimuli and can facilitate the behavioral reaction to visceral stimulation. To determine which RM and NRMC cells could play a role in generating the reaction to colorectal distension (CRD),...

The main function of Nucleus raphe magnus (NRM) is mostly pain mediation. Our previous study has demonstrated that oxytocin (OXT) regulates antinociception through the central nervous system rather than the peripheral organs, and pain stimulation increases OXT concentration in the NRM. The experiment was designed to investigate OXT in the rat NRM effect on pain modulation. The results showed th...

A physical and genetic map of Finegoldia magna (formerly Peptostreptococcus magnus) ATCC 29328 chromosome was constructed. The order of rare cleavage restriction fragments was determined by double digestion with the restriction enzymes I-CeuI, SgrAI, ApaI and PmeI, cross-hybridization and ApaI-linking clones. The size of the circular chromosome of F. magna was estimated to be 1.9 Mb. This strai...

In two patients with prosthetic valve endocarditis due to Peptostreptococcus magnus, blood cultures in the BacT/Alert and BACTEC 9240 systems were signal negative. The capability of the BacT/Alert system to detect various Peptostreptococcus species was assessed. P. magnus and P. anaerobius could not be detected, and subcultures remained negative. The growth in conventional media of these two sp...

Medullary raphe magnus (RM) on and off cells are thought to modulate spinal nociception by gating withdrawals evoked by noxious stimulation. To test whether withdrawal initiation is the target of RM modulation, we examined the relationship between on and off cell discharge and motor withdrawal evoked by noxious laser heat in halothane-anesthetized rats. The cellular responses of both cell types...

The Neotropical genus Alloraphes Franz belonging to the tribe Cyrtoscydmini is revised. Alloraphes is redefined based on a detailed morphological study, and Parastenichnaphes myrmecophilus (Franz) is transferred back to Alloraphes, where it was originally placed. Alloraphes jamaicae Franz, A. peruanus Franz, A. lenkoi Franz, A. yucatani Franz, A. chiapasensis Franz and A. myrmecophilus Franz, s...

Dux magnus gentis venteris saginati is considered to be a Scottish delicacy; however, depleting wild stocks have resulted in attempts to farm them. Selective breeding has been successful in modifying behaviour, increasing body length, reducing hair coat and improving fank (litter) size. However, there are still significant problems associated with the terrain in which they are farmed. This arti...
