Background: Early diagnosis of patients in the early stages of Alzheimer's, known as mild cognitive impairment, is of great importance in the treatment of this disease. If a patient can be diagnosed at this stage, it is possible to treat or delay Alzheimer's disease. Resting-state functional magnetic resonance imaging (fMRI) is very common in the process of diagnosing Alzheimer's disease. In th...

BACKGROUND There have been many attempts at explaining the underlying neuropathological mechanisms of auditory verbal hallucinations (AVH) in schizophrenia on the basis of regional brain changes, with the most consistent findings being that AVH are associated with functional and structural impairments in auditory and speech-related regions. However, the human brain is a complex network and the ...

A question to be addressed in the present study is how different the eyes-closed (EC) and eyes-open (EO) resting states are across frequency bands in terms of efficiency and centrality of the brain functional network. We investigated both the global and nodal efficiency and betweenness centrality in the EC and EO resting states from 39 volunteers. Mutual information was used to obtain the funct...

BACKGROUND The efficiency of nasal surgeries can be determined by objective or subjective methods. We have assessed the effect of nasal obstruction after different nasal surgeries using Acoustic Rhinometry (AR) and Nasal Obstruction Symptom Evaluation (NOSE) Scale. METHODS Between May 2011 and May 2012, 40 young adult patients and 10 healthy volunteers as control group who referred to ...

Background: Initial studies have shown that low-energy ultrasound stimulates living tissue cells to reduce regeneration or speed up their recovery. The purpose of this study was to examine the effects of various ultrasound parameters on the speed of recovery in injured sciatic nerves. Methods: NMRI mice (n = 200) with injured left paw, caused by crushing their sciatic nerves, were randomly sel...

background: the unified treatment approach (up), an emotion-focused cognitive-behavioral therapy that holds emotional processes as a central target of treatment, is applicable for disorders with strong emotional components. the aim of this study was to examine the effectiveness of emotion regulation intervention derivative from the up on emotional problems and quality of life among patients wit...

background: the impact of work-related musculoskeletal disorders (wrmsds) on functional performance of nigerian welders is unknown. this study investigated the prevalence, pattern and impact of wrmsds on functional efficiency among welders in alimosho local government, lagos state, nigeria.   materials and methods: this cross sectional survey involved 177 welders in a rural-urban area in nigeri...
