Morphological features of the subplate, the thalamic reticular complex and the ganglionic eminence, which represent three major transient structures of the human fetal forebrain, are summarized with special reference to their functional roles. The subplate harboring various neuronal types is an outstandingly wide zone subjacent to the cortical plate in the human fetal brain. Within the subplate...

Regeneration and functional recovery of the hypothalamoneurohypophysial system (HNS) in neurohypophysectomized rats treated with either saline or vasopressin (VP) were analyzed utilizing specific immunohistochemical and physiological measures. Neural lobe ablation combined with VP administration precipitated a profound diabetes insipidus (following cessation of VP delivery) that persisted for t...

OBJECTIVES The aim of this study was to investigate bone changes in the condyle, articular eminence and glenoid fossa in relation to the position of the articular disc. METHODS 148 temporomandibular joints (TMJs) of 74 symptomatic patients who underwent MRI were evaluated. The position of the disc was classified as either normal (N), disc displacement with reduction (DDwR), disc displacement ...

The role of ovarian hormones in the control of the quantity and activity of tyrosine hydroxylase (TyrOHase) in neurites of the median eminence of the rat was investigated. TyrOHase was quantified by an immunoblot assay using purified rat TyrOHase as the standard. Treatment of ovariectomized animals with progesterone, but not estradiol, resulted in a significant reduction in the amount of TyrOHa...

PURPOSE The objective of this study was to evaluate the computational reconstruction of the articular eminence of the temporomandibular joint (TMJ) based on magnetic resonance imaging (MRI) and semiautomatic volumetric segmentation techniques for morphological classification of the TMJ structure. MATERIALS AND METHODS A total of 36 MRI scans of TMJ individuals were selected and formatted by u...

UNLABELLED Dislocation of the temporomandibular joint occurs when the mandibular condyle exits the glenoidal cavity and remains anteriorly locked to the articular eminence. It is repetitive (recurrent dislocation), usually associated with mandibular hypermobility and inclination of the articular eminence. AIM This study intended to clinically and radiologically assess the technique of eminect...

Little is known of the neural sites of action for the pineal hormone, melatonin. Thus, we developed an in vitro autoradiographic method using 125I-labeled melatonin (I-MEL) to study putative melatonin receptors in rodent brain. We first determined optimal in vitro labeling conditions for autoradiographic detection of I-MEL binding sites in rat median eminence, the most intensely labeled area in...

This study evaluates the initial fixation strength of tibial eminence fracture repair using 1, 2, 3, and 4 sutures to determine the optimal number of sutures required to adequately secure the avulsed fragment to the tibia. Sixteen skeletally immature porcine knees were stripped of all soft tissues, isolating the femur-anterior cruciate ligament (ACL)-tibia complex. Type III tibial eminence frac...

Different treatment modalities are described in literature to treat mandibular recurrent dislocation, including intracapsular esclerosant injections, articular eminence reduction, soft tissues suture to limit condilar movement, and grafts or implants to create mechanical interference, like zygomatic arch down fracture or articular eminence increase by bone plates. In this paper, a patient with ...

STATEMENT OF THE PROBLEM Finding a significant relationship between temporomandibular joint (TMJ) morphology and the incidence of temporomandibular dysfunction (TMD) may help early prediction and prevention of these problems. PURPOSE The purpose of the present study was to determine the morphology of mandibular fossa and the articular eminence inclination in patients with TMD and in control g...
