A 25-year-old man presented with a maxillary transverse discrepancy, posterior cross bite, anterior open bite, molar and canine class III. Treatment included a corticotomy in the upper lateral and posterior teeth, a palatal expansor and a sectional archwire to assist the expansion. The following treatment phase included bonding with Incognito System lingual appliance, interproximal reduction to solve the crowding and bite blocks to control the verticality. Two months after the bonding intermaxillary class III elastics were used to solve the sagittal discrepancy and eight months after the bonding vertical elastics were used in order to solve the anterior open bite until the end of the treatment...

Autologous bone block grafting is an efficient technique to thicken an atrophied residual alveolar ridge. A variable degree of resorption, however, occurs due to graft remodeling. In this study, we hypothesize that under-preparation of implant socket would permit the dental implant to act as a bone expansor and thus compensate for the contraction in the augmented ridge width. For that reason, 10 patients received an autologous bone block graft that was obtained from the ramus of the mandible. Residual alveolar ridge width was measured on CBCT scans obtained before surgery (T0), after 2 months of healing (T1), after 4 months of healing just before implant placement (T2), and after 4 months of implant placement (T3)...

The expansor secundariorum is a smooth muscle of the chicken wing which receives a dense noradrenergic innervation and contains high concentrations of trophic activity for sympathetic neurons. Expansor cells were dissociated in trypsin and grown to confluency in standard nutrient medium. Medium that had been conditioned by expansor cells contained trophic activity for chick sympathetic nerves which differed from the activity which is found within the muscle prior to culture, in that it was effective on a different neuronal subpopulation...

We sought to examine further the regulation of muscarinic receptors in the developing expansor secundariorum, a smooth muscle of the avian wing. [(3)H]Quinuclidinyl benzilate binding was used as a measure of muscarinic receptors present in the muscle, which gradually decline in density from hatch during the following few weeks. Receptor loss can be prevented by denervation of the muscle immediately after hatch, but receptor density is not recovered by denervation in older birds. As the major innervation is provided by sympathetic, noradrenergic fibres with no evidence of a cholinergic input, the action of several pharmacological agents known to affect noradrenergic transmission was examined...

We demonstrate that, by changing the altitude and the azimuth incident angles on the gratings of the conventional grating-pair compressor used in chirped-pulse amplification, an extra degree of freedom is added. This results in a continuous adjustment of second-, third-, and fourth-order dispersions, which allows one to compensate for those dispersions that originated in the expansor or in the amplifier medium as a result of material dispersion or self-phase modulation, even with small out-of-plane tilts of the expansor and compressor...

This article describes, for the first time, the supraperiostic technique used for aesthetic purposes to remedy hemiatrophy, genu valgum, poliomyelitis sequela, and thin legs. For genu valgum and thin legs, a solid prosthesis was used, whereas for severe hemiatrophy a double light prosthesis was used as a tissue expansor, with excellent reports. The advantages of this technique are delineated further in this article.

INTRODUCTION: The suitable cutaneous covering for big defects secondary to the removal of giant pigmented lesions has not been obtained yet. Nevus that affect a corporal surface bigger than 75%, have no curative treatment and in the cases of smaller nevus therapeutical possibilities are complex, take too much time and provide unfavourable aesthetic results. MATERIAL AND METHODS: Nineteen patients suffering giant congenital nevus (GCN) have been treated in the last eight years...

Shock is one of the most difficult problems an obstetrician can face. Hemorrhage is the main reason of shock. A descriptive and retrospective research was conducted at Instituto Nacional de Perinatología, from January 1992 to May 1996, including all patients admitted to the intensive care unit with diagnosis of shock. There were found 90 cases with diagnosis of shock, 82 were hipovolemic, and 8 cases had the septic kind of shock. The average of age was 32.2 years, with a gestational age between 6.2 to 41.4 weeks ...

The functional effects of chronic administration of 60 mg kg-1 chloroquine or quinacrine given as daily intraperitoneal injections for 84 days on normal and denervated expansor secundariorum muscles, a smooth muscle from the wing of chicks wholly innervated by noradrenergic nerves, have been investigated. Administration of quinacrine, but not chloroquine, blocked responses to noradrenergic nerve stimulation. Surgical denervation abolished responses to nerve stimulation. Contraction of the expansor muscle induced by noradrenaline was not changed by chronic administration of chloroquine or quinacrine, and both drugs did not influence denervation supersensitivity of expansor muscles to noradrenaline...

Previous studies from this laboratory have used antisera to aldehyde-conjugated ovalbumin to localize ovalbumin-like immunoreactivity within a subpopulation of sensory neurons. We have now combined retrograde tracing and immunohistochemical procedures to identify the tissues innervated by sensory neurons which are either immunoreactive or non-immunoreactive for ovalbumin. The fluorescent tracer Di-I was administered to feather follicles, flexor ulnar muscle, subdermis, expansor secundariorum, heart and liver and identified seven days later within corresponding dorsal root ganglia...

The effects and mechanisms of action of dopamine on the lower oesophagus and expansor secundariorum muscle (ESM) of chicks and on the bladder of rat have been examined. Dopamine contracted the lower oesophagus in a concentration-related fashion but failed to contract the muscle from chicks pretreated with reserpine or p-chlorophenylalanine. Contraction of the ESM by dopamine was antagonized by prazosin but not by propranolol. Supersensitivity of the ESM to dopamine observed 3 or 28 days after surgical denervation of the muscle was comparable...

Breast augmentations using a transaxillary subpectoral approach are usually performed under general anesthesia. This article describes a technique that uses local infiltrative anesthesia in breast augmentation, adenomastectomies with immediate breast reconstruction, and when placing breast expansors. Large anesthetic solutions with vasoconstrictor and long-acting effects are prepared. The axila, the subpectoral space, and a surrounding area of 3 cm outside the demarcation limits are infiltrated. Minimal bleeding, long-lasting effects, and a considerable postoperative analgesic effect are some of the advantages of this procedure...

1. The effects of some alpha-adrenergic agonists and antagonists on electrically-evoked contractions and tension of chick expansor secundariorum muscle (ESM), and dependence of these events on extracellular calcium was investigated. 2. Both train and continuous electrical stimulation can produce regular contractions in preparations obtained from 40-60 day old chicks. 3. Clonidine had a biphasic action on the contractions produced by train electrical stimulation. In concentrations ranging from 10(-8) to 3 x 10(-7) M, clonidine decreased the contraction amplitude, but in higher concentrations, it caused an increase in both the muscle tension and the contraction amplitude...

A number of 241 patients with meningococcal infection, treated between 1972 and 1978, is analysed. Some new therapeutic patterns are established based on the application of the prognosis score of Stiehm. With these patterns consisting in the use of volume expansors with anti-aggregating properties and low dosage prophylactic heparin administration, authors have considerably improved their results reported in 1972, succeeding in diminishing the global mortality to 3.73%, a figure inferior to that of all known series to date...

The mechanisms by which acetylcholine (ACh) and noradrenaline (NA) induce muscle contraction were examined in the chick expansor secundariorum muscle in early life, because responsiveness to ACh disappeared and responsiveness to NA persisted during development. ACh-induced contractions decreased with lowered temperature, while NA-induced contractions increased between 30 and 20 degrees C. Papaverine depressed and antagonized NA-induced contractions, but did not depress ACh-induced contractions. The second application of ACh in Ca2+-free solution produced a negligible contraction...
