Role of magnetic resonance imaging (MRI) including diffusion weighted images (DWIs) in assessment of parotid gland masses with histopathological correlation

Conclusion Illdefined border, diffuse growth pattern and infiltration of surrounding structures are specific MR signs of parotid mass malignancy. Involvement of both parotid lobes, low T2WIs signal and high degree of contrast enhancement are suggestive signs of malignancy. ADC value had appreciable add value in parotid mass evaluation.

CONCLUSION: This study shows that participants with dyslexia fail to use normal brain regions specialized in language processing, but rather use different areas. PMID: 32086175 [PubMed - as supplied by publisher]

This article reviews the application of an alternative method, functional near-infrared spectroscopy (fNIRS), to the study of cerebral oxygenation changes in MCI and dementia. We synthesized 36 fNIRS studies that examined hemodynamic changes during both the resting state and the execution of tasks of word retrieval, memory, motor control, and visuospatial perception in MCI and dementia. This qualitative review reveals that (amnestic) MCI and AD patients have disrupted frontal and long-range connectivity in the resting state compared to individuals with normal cognition (NC). These patients also exhibit reduced frontal oxyg...

Hereby, a smart tumor environment (TME) responsive theranostic agent based on CuS@mSiO2@MnO2 nanocomposites was fabricated by a facile method. When the nanocomposites entered tumor, the drug release was triggered by multi-model response of NIR i...

Abstract Multiple sclerosis (MS) is a chronic inflammatory and demyelinating disease of the central nervous system. The disease affects more women than men and often is diagnosed during a woman's childbearing years. Typical clinical presentations of the disease are extensive and variable, with symptoms that include dysregulated mood, fatigue, vision problems, weakness, tremor, imbalance, abnormal sensations, bladder dysfunction, and heat sensitivity. If a woman aged 15-50 years experiences these neurologic symptoms in isolation or combination, and the symptoms are not explained by other underlying medical conditio...

Conclusions: This T1w-MRI study demonstrated focused regional CC atrophy and texture alterations limited to the callosal area III (which comprises fibers projecting into the primary motor cortices) in PLS, in comparison to a higher variability in CC size in ALS.

A matched cohort of 25 neurotypical adult males served as controls. Dependent variables were extracted from ...

ConclusionsCardiac effects after severe late-onset PE were small and transient. This indicates that left ventricular hypertrophy after severe late-onset PE may be a secondary physiologic response to increased peripheral resistance in PE. Vascular mechanisms rather than persistent cardiac hypertrophy postpartum may be the culprit for increased long-term cardiovascular risk after PE.
