the adaptive response (ar) is a phenomenon by which cells exposure to sublethal doses of dna-damaging agents (non-mutagenic dose of chemical or radiation), known as conditioning treatment (ct), leads to increased resistance to a subsequent exposure to a higher dose of the same or other agents, known as challenge treatment (cr). the adaptive response (ar) induced by radiation in human lymphocyte...

OBJECTIVE To evaluate the analgesic effect of CT-guided microinvasive intervention on refractory carcinous pain. METHODS A total of 23 patients with poor response to drug therapy for carcinous pain were selected: 6 patients underwent CT-guided neurolytic celiac plexus block (NCPB), 5 patients underwent CT-guided(125)I implantation and 12 patients underwent combined CT-guided NCPB and CT-guide...

background: the artificial neural networks (anns) are useful in solving nonlinear processes, without the need for mathematical models of the parameters. since the relationship between the ct numbers and material compositions is not linear, ann can be used for obtaining tissue density and composition. objective: the aim of this study is to utilize ann for determination of the composition and mas...

BACKGROUND Although both cognitive therapy (CT) and interpersonal psychotherapy (IPT) have been shown to be effective treatments for major depressive disorder (MDD), it is not clear yet whether one therapy outperforms the other with regard to severity and course of the disorder. This study examined the clinical effectiveness of CT v. IPT in a large sample of depressed patients seeking treatment...

conclusions an extremely rare condition, a spontaneous intracranial pneumocephalus with skull base defect origin could be considered as a possible diagnosis in patients with sudden and severe headache. we can safely conclude that medical treatment and close follow-up is an effective mode of therapy in this patient. introduction spontaneous pneumocephalus without any pathological condition is ve...

The purpose of this study was to provide an experimental test of the theory of change put forth by A. T. Beck, A. J. Rush, B. F. Shaw, and G. Emery (1979) to explain the efficacy of cognitive-behavioral therapy (CT) for depression. The comparison involved randomly assigning 150 outpatients with major depression to a treatment focused exclusively on the behavioral activation (BA) component of CT...

Pachygyria or incomplete lissencephaly is a developmental condition due to abnormal migration of neurons. The association of seizures in this condition warrants investigation like electroencephalogram (EEG) and magnetic resonance imaging (MRI). 18F-flurodeoxyglucose positron emission topography computed topography (18F-FDG PET/CT) has a potential role in commenting of wide...

communication between subarachnoid and per lymphatic spaces can be due to a deficiency of lamina crib rosa (stapes gusher). recognition of the condition may alter the course of treatment that can avoid perilymph gushing. a five-year-old boy presented with a history of congenital hearing loss and recurrent meningitis. the computed tomography (ct) of the temporal bone showed severe bilateral dysp...

Cognitive therapy (CT) and interoceptive exposure (IE) as treatments of panic disorder without agoraphobia were compared in a sample of 69 patients, randomly allocated to condition. There were no significant differences between treatments as to reductions in panic frequency, daily anxiety levels and a composite questionnaire score, at posttest after the 12-session treatment, and at both follow-...
