Miniaturización de acopladores utilizando la técnica fractal en banda L.

Telemática, 2018
La amplificación distribuida requiere el uso de acopladores direccionales  tanto de líneas acopladas como híbridos de 90 grados. El trabajo en la banda de frecuencia de 900-1200 MHz requiere dispositivos diseñados a parámetros distribuidos.

Ultrasound in the Diagnosis of Chronic Inflammatory Demyelinating Polyneuropathy in Patients With Diabetic Neuropathy

Clinical Neuroimaging
Introduction The diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP) in patients with diabetic sensorimotor polyneuropathy (DSP) is challenging when both diseases coexist, as patients with DSP may have demyelinating features in nerve ...

Is Fecal Calprotectin an Applicable Biomarker of Gut Immune System Activation in Chronic Inflammatory Demyelinating Polyneuropathy? – A Pilot Study

Frontiers in Human Neuroscience, 2021
Introduction: Chronic inflammatory demyelinating polyneuropathy (CIDP) is a complex autoimmune disease caused by dysregulated response to not fully recognized antigens. Some association between CIDP and inflammatory bowel disease (IBD) has been reported,

Multiparametric Quantitative MRI of Peripheral Nerves to Differentiate Demyelinating From Axonal Polyneuropathies

Journal of Magnetic Resonance Imaging, Volume 64, Issue 4, Page 1077-1088, October 2026.
ABSTRACT Background Differentiating demyelinating from axonal polyneuropathies helps for accurate diagnosis and treatment. However, the current clinical tools lack sensitivity to confirm demyelination in peripheral nerves, particularly for proximal nerves.

Unexpected Conduction Blocks in SORD‐Related Distal Motor Neuropathy: A Case Report

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Distal weakness requires an extensive differential diagnosis. In this case, conduction blocks indicated multifocal motor neuropathy, but immunotherapy proved ineffective. Ultimately, genetic testing revealed a sorbitol dehydrogenase mutation, highlighting the importance of combining electrophysiological findings with molecular studies in cases

Quantitative Analysis of Electrophysiological Characteristics of CIDP and CMT Type 1: Sensory Nerve Research

Korean Journal of Clinical Laboratory Science, 2021
Charcot-Marie-Tooth disease (CMT) is a slowly progressive hereditary degenerative disease and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder characterized by weakness and sensory deficits.

Novel therapies in CIDP

Journal of Neurology, Neurosurgery & Psychiatry
Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a heterogeneous but clinically well-described disease within circumscribed parameters. It is immunologically mediated through several poorly understood mechanisms. First-line therapies with steroids, intravenous immunoglobulin (IVIG) or plasma exchange are each effective in about two ...

The characteristics of chronic inflammatory demyelinating polyneuropathy in patients with and without diabetes--an observational study.

PLoS ONE, 2014
IntroductionWe aimed to determine whether the clinical characteristics and electrodiagnostic classification of nerve injury, and response to treatment differed in patients diagnosed with chronic inflammatory demyelinating polyneuropathy (CIDP) with and ...
