introduction: striae distensae (sd) are a frequent skin condition for which treatment remains a challenge. the 1540-nm non-ablative fractional laser (star lux 500) has been shown to improve atrophic scars by increasing the amount of dermal collagen. to assess the safety and efficacy of the star lux 500 laser in the treatment of mature hypopigmented striae in persian people (striae alba). method...

this case is a 19-year-old soldier who suffered a combined elbow dislocation and posterior monteggia fracture and dislocation (type ii). the ulna fracture was managed by orif. the elbow dislocation was managed by closed reduction and immobilization in 900 flexion. the posteriorly dislocated radial head was kept reduced by a transarticular pin. after 6 months elbow and forearm motion was restric...

The hypothalamus has historically been subdivided into nuclei, agglomerations of cell bodies that are visually distinct in histological sections. Regulatory functions of metabolism have been assigned to the various hypothalamic nuclei principally by analysis of animals with lesions of individual nuclei but also via various means of stimulation, such as cooling or heating probes. Biochemical and...

To test the hypothesis that glucokinase is a critical regulator of neuronal glucosensing, glucokinase activity was increased, using a glucokinase activator drug, or decreased, using RNA interference combined with calcium imaging in freshly dissociated ventromedial hypothalamic nucleus (VMN) neurons or primary ventromedial hypothalamus (VMH; VMN plus arcuate nucleus) cultures. To assess the vali...

21 Vibrissa motoneurons (vMNs) generate rhythmic firing that controls whisker movements, even 22 without cortical, cerebellar or sensory inputs. vMNs receive serotonergic modulation from brainstem 23 areas, that mainly increases their persistent sodium conductance (gNaP), and, possibly, phasic input 24 from a putative central pattern generator (CPG). In response to serotonergic modulation or ju...

The ovarian hormones, estradiol (E) and progesterone (P) facilitate the expression of sexual behavior in female rats. E and P mediate many of these behavioral effects by binding to their respective intracellular receptors in specific brain regions. Nuclear receptor coactivators, including Steroid Receptor Coactivator-1 (SRC-1) and CREB Binding Protein (CBP), dramatically enhance ligand-dependen...

Understanding sex differences in stress regulation has important implications for understanding basic physiological differences in the male and female brain and their impact on vulnerability to sex differences in chronic medical disorders associated with stress response circuitry. In this functional magnetic resonance imaging study, we demonstrated that significant sex differences in brain acti...

tumefactive fibroinflammatory lesions (tfls) are rare idiopathic benign fibrosclerosing lesions that clinically simulate a malignancy. tfls are seen more frequently in males between 10 and 74 years of age. the usual site of involvement is the head and neck region, but rarely the extremities may be involved. coexisting fibrosclerotic processes have been reported including retroperitoneal fibrosi...

statement of problem: failure of endodontic treatment is determined on the basis of radiographic findings and clinical signs and/ or symptoms of the treated teeth. purpose: the purpose of this study was to determine endodontic treatment failure in relation to various factors influencing it in teeth with periapical lesions (clinically and radiographically). materials and methods: teeth which had...

introduction: chronic sclerosing sialadenitis is a relatively uncommon disorder of the salivary gland. because of its clinical similarity to a salivary gland neoplasm, this condition has been known as kuttner tumor and is classified as a tumorlike lesion. case report: this is the first reported case of bilateral kuttner tumor of the submandibular glands in iran. it was initially diagnosed as a ...
