our case was a 48-year-old man with cervical pain radiatingto the upper limbs. imaging showed an intradural tumor with extradural component encasing the vertebral artery.thetumor diagnosed asa neurinomaand had been removed surgically.the post operationmagnetic resonance imagingshowed that the tumor was completely removed andthe vertebral arterywas intact at theentire length.the goal of surgery ...

abstract our patient was a 43-year-old woman with a suboccipital headache and pain in the upper cervical region from 3 years ago with a progressive generalized weakness in the last 3 months. neuroimaging study showed a dumbell shaped lesion with compression of the spinal cord in the cervical region that was identified as a neurinoma. the tumor had been completely removed by surgery but after th...

Aim: This study is aimed to evaluate the importance of collagen fi brils in the adhesion of diff erent self-etching adhesive materials to dentin. Methods: Sixty Class V restorations were prepared on the buccal and lingual surfaces of 30 recently extracted human premolars, with the cervical margins in dentin and the occlusal margins in enamel. These restorations were distributed to three groups ...

Effect of supplementation of ascorbic acid, caffeine and chloroquine diphosphate in the dilutor on post-thaw quality of spermatozoa was studied. Thirty-two semen ejaculates (8 each from 2 Holstein Friesian and 2 crossbred; 50% Friesian x 50% Haryana) were studied. Ascorbic acid, caffeine and chloroquine diphosphate were added in Tris-egg yolk-glycerol (control) extender at the concentration of ...

One of the most valid and efficient models of long rod projectile penetration in homogeneous targets is Tate and Alekseevskii’s (A&t) model. Based on Tate’s model, the present research tries to calculate the optimum speeds to achieve the maximum penetration depth in the homogeneous targets. The proposed collision speed-penetration depth diagrams are developed using Tate’s model. In this way, va...

wc studied the correlation between preoperative cervical cytology, postoperative clinicopathologic findings, and sites of metastasis from so surgically staged patients with endometrial carcinoma tliirty-faur patients (68%), liad normal cervical cytology, ami 16(32%) had malignant preoperative cervical cytology. malignant cervical smears were statistically correlated with surgical stage (p = 0.0...

Ingestion of foreign bodies is a common problem in the otolaryngology practice. Reports of extraluminal migration of the foreign bodies from the upper aerodigestive tract are rare. Penetration and extraluminal migration of ingested foreign bodies may cause severe vascular and suppurative complications, even death. We report a 4-year-old girl who presented with a mass and partial extrusion of a ...

This study aimed to evaluate the effects of the light curing method and resin composite composition on marginal sealing and resin composite adaptation to the cavity wall. Cylindrical cavities were prepared on the buccal or lingual cervical regions. The teeth were restored using Clearfil Liner Bond 2V adhesive system and filled with Clearfil Photo Bright or Palfique Estelite resin composite. The...

The clinical, pathological, and microbiological features of 18 pregnancies complicated by intrauterine infection with Candida sp. are described. Chorioamnionitis with Candida sp. can be recognised macroscopically at birth. Penetration of the umbilical cord and membranes is associated with an intense fetal inflammatory response. The infection characteristically presents in infants of very low bi...

It has been shown that the gestagen component of oral contraceptives changes the composition of the cervical mucus so as to make sperm penetration difficult. Endometrial changes and changes in the normal patterns of tubal and uterine motility have been described. Ovulation is inhibited by inhibition of ovarian response to gonadotrophins or by inhibition of the formation and/or release of endo...
