The use of pedicle screw instrumentation in the spine has evolved over the last two decades. The initial use of pedicle screws began in the lumbar spine. As surgeons have become more comfortable with the complex anatomy required for accurate screw placement, the use of pedicle instrumentation has evolved to include their use in the thoracolumbar and thoracic spine. The impetus behind their incr...

Objective- The aim of this study was to compare the duration of surgery as well as some physiological stress indicators in large breed dogs undergoing open ovariohysterectomy with or without use of uterine hook. Design- Experimental study Animals- Fourteen healthy dogs underwent open OHE with (N=7) or without use of uterine hook (N ...

OBJECTIVES Foreign bodies of the external auditory canal are a relatively common problem in emergency departments. Repeated attempts at removal with standard instrumentation can lead to significant ear injury. Recent case reports of using cyanoacrylate impregnated cotton buds suggest this is less traumatic and well tolerated by patients. No studies on this method have been performed. The object...

background: the purposes of the present study were morphometric characteri-zation of rostellar hooks of taenia multiceps and to investigate the association of hook length variation and the variability within two mitochondrial genes of sheep isolates of the parasite. methods: up to 4500 sheep brains were examined for the presence of c. cerebralis . biometric characters based on the larval rostel...

We introduce a quasisymmetric generalization of Berele and Regev’s hook Schur functions and prove that these new quasisymmetric hook Schur functions decompose the hook Schur functions in a natural way. In this paper we examine the combinatorics of the quasisymmetric hook Schur functions, providing analogues of the RobinsonSchensted-Knuth algorithm and a generalized Cauchy Identity. Résumé. Nous...

INTRODUCTION Despite dating more than 30 years after the first laparoscopic appendectomy, ileocecal appendix resection is still performed by laparotomy in more than 90% of cases, in our country. AIM To describe a technique for laparoscopic removal of the ileocecal appendix with three portals, at low cost and very good aesthetic appearance. TECHNIQUE Three incisions, one umbilical and two su...

The structure of the Gram-positive flagellum is poorly understood, and Bacillus subtilis encodes three proteins homologous to the flagellar hook protein from Salmonella enterica. Here we generated a modified B. subtilis hook protein that could be fluorescently stained using a cysteine-reactive dye. We used the fluorescently labeled hook to demonstrate that FlgE is the hook structural protein an...
