تهیه نقشه جنگلها، به‌ویژه در مناطق کوهستانی مشکل و پرهزینه است. برای این منظور استفاده از داده‌های ماهواره‌ای راه ‌حل مناسبی به‌نظر می‌رسد. در این بررسی از داده‌های سنجنده Landsat ETM+ برای تهیه نقشه طبقه‌بندی تراکم تاج‌پوشش جنگل با استفاده از مدل FCD در حوضه شفارود گیلان استفاده شده است. نقشه تراکم جنگل با استفاده از طبقه‌های تراکم تاج‌پوشش 25-5، 50-25، 75-50 و 100-75 درصد و یک طبقه فاقد جنگل ...

PURPOSE Focal cortical dysplasia (FCD) is the most common pathological diagnosis in patients who have undergone surgical treatment for intractable neocortical epilepsy. However, presurgical identification of MRI abnormalities in FCD patients remains difficult, and there are no highly sensitive imaging parameters available that can reliably differentiate among FCD subtypes. The purpose of our st...

BACKGROUND Focal cortical dysplasias (FCD) are local disturbances of neocortical architecture and a common cause of pharmaco-resistant focal epilepsy. Little is known about the pathomechanisms leading to architectural abnormalities associated with FCD. RESULTS In the present study we compared 52 FCD cases originating from the frontal or temporal lobe with or without Ammon's horn sclerosis (AH...

PURPOSE Cortical dysplasia (FCD) is a frequent cause of epilepsy in childhood. Two major pathological variants are distinguished, FCD type I and II. The aim of the study was to characterize differences between FCD type I and II with respect to imaging and EEG findings, clinical and neuropsychological presentations, and surgical outcome. METHODS Forty children with refractory epilepsy and hist...

PURPOSE   Focal cortical dysplasias (FCD) are localized regions of malformed cerebral cortex and are very frequently associated with epilepsy in both children and adults. A broad spectrum of histopathology has been included in the diagnosis of FCD. An ILAE task force proposes an international consensus classification system to better characterize specific clinicopathological FCD entities. MET...

Focal cortical dysplasia (FCD) II and I are major causes for drug-resistant epilepsy. In order to gain insight into the possible correlations between FCD II and FCD I, different clinical characteristics and immunohistochemical expression characteristics in FCD I and II were analyzed. The median age of onset and duration of epilepsy in FCD I and FCD II patients were 2.1 years and 5.3 years vs 2....

PURPOSE To characterize the genetic basis and phenotype of inherited Fuchs corneal dystrophy (FCD). METHODS DNA from blood was used for genome-wide linkage scans with tandem repeat polymorphisms. Mutation detection involved sequencing PCR-amplified exons. Families with FCD were clinically evaluated and graded on the Krachmer severity scale. Confocal specular microscopy visualized the morpholo...

BACKGROUND AND PURPOSE Focal cortical dysplasia (FCD) covers a spectrum of conditions in which the neuropathologic and electroclinic presentations and the surgical outcomes vary. The aim of this study was to identify the MR features of histologic subtypes of FCD that would be useful for differential diagnosis. METHODS We reviewed the MR data of 49 patients treated surgically for intractable p...

OBJECTIVE Alterations in γ-aminobutyric acid (GABA)-ergic cortical neurons have been reported in focal cortical dysplasia (FCD)Ia/IIIa, a malformation of cortical development associated with drug-resistant epilepsy. We compared numbers of neurons containing calcium-binding proteins parvalbumin (PV), calbindin (CB), and calretinin (CR) and densities of respective fibers in lateral temporal lobe ...

PURPOSE To analyze the expansion of CTG18.1 allele associated with Fuchs' corneal dystrophy (FCD) in our large cohort of late-onset FCD cases. METHODS CTG repeats within the CTG18.1 allele were estimated by short tandem repeat (STR) and triplet primed PCR (TP-PCR) assays in our large cohort of 574 late-onset FCD cases and 354 controls and large multigeneration familial cases. The age versus s...
