Acute and delayed effects of concentric and eccentric exercise on quantitative muscle MRI.

Conclusions Longitudinal effects of concentric and eccentric exercise can be detected by both T2 and MTR, but T2 is more sensitive to subtle alterations. PMID: 30227725 [PubMed - as supplied by publisher]

The objective of the study was to identify the relationship between subcortical gray matter (GM) volumes and juvenile myoclonic epilepsy (JME).MethodsWe analyzed the brain magnetic resonance imaging (MRI) scans that were performed during the time of the diagnosis of epilepsy by using voxel-based morphometry (VBM) method. The volumetric three-dimensional sequence was used for structural investigation. The volumes of the thalamus, caudate nucleus, pallidum, and putamen were measured in both hemispheres of patients with JME, patients with generalized tonic–clonic seizures alone (GTCS) (as a disease control group) and he...

ConclusionsWe illustrate the neural networks involved in conceptual thought through a unique patient population and argue that PFC supports this function through activation of a widespread network.

Fridjonsson, Michael L. JohnsAbstractForward osmosis (FO) and reverse osmosis (RO) membrane processes differ in their driving forces: osmotic pressure versus hydraulic pressure. Concentration polarization (CP) can adversely affect both performance and lifetime in such membrane systems. In order to mitigate against CP, the extent and severity of it need to be predicted more accurately through advanced online monitoring methodologies. Whilst a varie...

Conclusions“Hypoflexible” CCN may involve in anxiety syndrome. Low flexibility in DMN may be indicative of hysteresis. These suggest an important pathophysiology of depressive manifestation of MDD. The antidepressant-induced normalization of the “hypoflexibility” suggests a selective pathway through which antidepressants may alleviate symptoms in depression.

We report a case in which diffusion-weighted magnetic resonance imaging (DWI) demonstrated renal artery stenosis-related renal ischemia and the therapeutic efficacy of revascularization. The patient was a 73-year-old man, who underwent descending thoracic aortic replacement due to DeBakey IIIb chronic aortic dissection, and who showed progressive renal dysfunction due to right renal artery stenosis caused by false lumen thrombosis. DWI demonstrated a decreased apparent diffusion coefficient (ADC) in the right kidney, indicating renal ischemia. Angioplasty with stenting restored renal perfusion and improved the renal functi...

Although he archived negative sputum culture two months ago, sputum culture tests revealed the newly isolation of Mycobacterium abscessus repeatedly. Chest computed tomography showed newly-appeared extra-pulmonary mass lesion in contact with a cyst at the bottom of his right lung. From the results o...

Conclusions: Our study demonstrated that the rich-club reorganization in functional brain networks is characterized by switching of rich-club nodes between the high-order cognitive and sensory and motor networks during propofol-induced alteration of consciousness and natural sleep. These findings will help understand the common neurological mechanism of pharmacological and physiological unconsciousness.

Authors: Baranowska-Wójcik E, Szwajgier D Abstract Introduction: Alzheimer's Disease (AD) is a progressive neurodegenerative pathology characterised by the presence of neuritic plaques and neurofibrillary tangles. The most important markers in AD pathology include excessive accumulation of amyloid beta (Aβ42) and phosphorylated tau (P-tau) proteins. One of the possible therapeutic strategies entails the elimination of such deposits by inhibiting Aβ aggregation. For years, one of the major problems in the treatment of AD has been the limited ability to deliver drugs to the brain for reasons related to ...

Publication date: Available online 21 January 2020Source: NeuropsychologiaAuthor(s): Lily Tao, Miaomiao Zhu, Qing CaiAbstractVerbal fluency test, a type of word generation task, is a commonly used neuropsychological assessment. Among the healthy population, it has been used to assess verbal ability, but also executive functions. In the clinical field, verbal fluency has been used to support the diagnoses of a number of neuropsychological disorders. However, existing evidence do not allow for clear conclusions on whether such nonlinguistic uses of verbal fluency test are justified. The present study therefore investigated t...

So far, the image data input to classifier mainly focus on 2D or 3D images. Although some functional imaging technologies, such as functional magnetic resonance imaging (fMRI), generate 4D data which contain both spatial and time-varying information of the brain, for the lack of suitable 4D image processing algori...
