Central injections of neuropeptide Y (NPY) increase food intake in Syrian hamsters; however, the effect of NPY on sexual behavior in hamsters is not known nor are the receptor subtypes involved in feeding and sexual behaviors. We demonstrate that NPY inhibits lordosis duration in a dose-related fashion after lateral ventricular injection in ovariectomized, steroid-primed Syrian hamsters. Under ...

restoration of the sagittal alignment is one of the fundamental goals in scoliosis correction surgery. having an increase in popularity of segmental spinal instrumentation, thoracic kyphosis (tk) is often sacrificed to achieve frontal and axial plane correction. patients with a lenke type 1 deformity underwent selective thoracic fusion (lowest instrumented vertebra of t12 or l1) using correctiv...

ABSTRACT Objective: Evaluate the influence of most used surgical positioners for lumbar lordosis (LL) in asymptomatic individuals. Methods: Cross-sectional study based on demographic data and radiographic parameters For this study, 16 volunteers, 15 males, one female were selected, average age was 24.6 years. They submitted to lateral radiographs spine orthostasis use following positioners: gel...

ABSTRACT Introduction: Spinopelvic parameters related to sagittal balance have become increasinglyimportantamong spine surgeons due their correlation with patient satisfaction rates. Objective: The goal of this study was evaluate changes in spinal after lumbar surgery using PLIF, the posterior interbody fusion technique. Methods: sample consisted adult patients degenerative disease submitted ar...

The incidence of symptomatic adjacent segment pathology (ASP) after fusion surgery for adult low-grade isthmic spondylolisthesis (IS) has been reported to be relatively low compared with other lumbar disease entities. However, there has been no study of symptomatic ASP incidence using posterior lumbar interbody fusion (PLIF) with pedicle screw instrumentation. We investigated the incidence of s...

It is widely believed that using a pillow that allows appropriate neck support to maintain cervical lordosis during sleep can lead to better quality sleep.Conversely, use of the wrong type of pillow can compromise pain-sensitive structures and produce waking symptoms, such as cervical pain and stiffness, headaches, and arm pain; and this in turn results in reduced sleep quality. Therefore, the ...

BACKGROUND Ovarian steroids regulate sexual receptivity in the female rat by acting on neurons that converge on proopiomelanocortin (POMC) neurons in the arcuate nucleus of the hypothalamus (ARH) that project to the medial preoptic nucleus (MPN). Estradiol rapidly activates these neurons to release β-endorphin that activates MPN μ-opioid receptors (MOP) to inhibit lordosis. Lordosis is facilita...

We have observed that intracerebroventricular (icv) injection of selective N-methyl-D-aspartic acid (NMDA)-type glutamatergic receptor antagonists inhibits lordosis in ovariectomized (OVX), estrogen-primed rats receiving progesterone or luteinizing hormone-releasing hormone (LHRH). When NMDA was injected into OVX estrogen-primed rats, it induced a significant increase in lordosis. The interacti...

Study Design Retrospective analysis. Purpose Our hypothesis is that the surgical correction of adolescent idiopathic scoliosis (AIS) maintains normal sagittal alignment as compared to age-matched normative adolescent population. Overview of Literature Sagittal spino-pelvic alignment in AIS has been reported, however, whether corrective spinal fusion surgery re-establishes normal alignment r...
