Bulbar urethral ischemic necrosis (BUIN) is an iatrogenic entity resulting from repeated attempts at performing anastomotic urethroplasty for pelvic fracture injuries. Etiologically speaking, BUIN related to a compromised blood supply of the bulbar urethra, which normally relies on anterograde arteries and retrograde recurrent branches dorsal penile arteries, through glans. At each transection ...

The Greater Antilles islands of Cuba, Hispaniola, Puerto Rico and Jamaica plus the Virgin Islands host fragments fossil convergent margin that records Cretaceous subduction (operated for about 90 m.y.) American plates beneath Caribbean plate ensuing arc-continent collision in Late Cretaceous-Eocene time. “soft” between Arc (GAA) Bahamas platform (and Maya Block western Cuba) preserved much marg...

The current surgical approach to the uncomplicated bulbar urethral stricture began in 1993 when El-Kasaby et al . [ 1 ] described the repair of anterior urethral strictures using an oral mucosa graft, including eight patients who underwent bulbar urethroplasty. In 1996, Morey and McAninch [ 2 ] fi rst described ventral onlay oral mucosa urethroplasty, suggesting suturing of the oral graft in th...

It is suggested that the brain response of a food odour sensed retro-nasally is related to satiation. The extent of retro-nasal aroma release during consumption depends on the physical structure of a food, i.e. solid foods generate a longer, more pronounced retro-nasal aroma release than liquid foods. The aim of this study was to investigate if a beverage becomes more satiating when the retro-n...

Retronasal (retro) and/or oral-cavity-only (OeD) smelling of vapor-phase agonists for the trigeminal chemoreceptive ion channel TRPM8 was studied. In a retro and OeD identification experiment. 1 of 6 previously practiced identifications (ID) was selected on a computer display under forced-choice conditions. Analyses of variance (ANOV A) found differences across odorants and retro and OeD. and f...

It is not known whether administration of contrast agent via retro-orbital injection or the tail vein route affects the efficiency of dynamic contrast-enhanced magnetic resonance imaging (MRI). Therefore, we compared the effects of retro-orbital and tail vein injection on the kinetics of the contrast agent used for MRI in mice. The same group of nine healthy female mice received contrast agent ...

This investigation was undertaken to evaluate the functional contribution of the peptide backbone of oxytocin in its interaction with receptor. Corey-Pauling-Koltun models of (Gly-7) deaminooxytocin, deaminotocinamide, and their respective retro-D-analogs built in any specific conformation (e.g., the Walter-Urry model for oxytocin) have a quai-equivalent topochemical arrangement of amino-acid s...

Three analogues of the model peptide of sequence IRGERA corresponding to the COOH-terminal residues 130-135 of histone H3 were synthesized, and their antigenicity, immunogenicity, and resistance to trypsin were compared to those of the natural L-peptide. The three analogues correspond to the D-enantiomer, containing only D-residues, and two retro-peptides containing NH-CO bonds instead of natur...

ACCORDING to the doctrine that the nervous system is organized as a series of levels, that portion of the brain stem lying immediately above the spinal cord, and described as bulbar, has traditionally been regarded as a level contributing excitatory influences to motor outflows. The basis for this view is the observation, f&t made by Sherrington (ll), that decerebration leaving only the bulbar ...

Objectives. To review the available literature describing the three most common approaches for buccal mucosal graft (BMG) augmentation during reconstruction of bulbar urethral strictures. Due to its excellent histological properties, buccal mucosa graft is now routinely used in urethral reconstruction. The best approach for the placement of such a graft remains controversial. Methods.
