Sleeve lobectomy (SL) makes it possible to resect centrally located lung carcinoma oncological correct while protecting healthy lung tissue. However, this procedure is often limited with conventional video-assisted thoracoscopic surgery, due to the limited mobility of the rigid and long instruments and the limited visualization. Therefore, these interventions are often still performed in the open conventional technique with the well-known disadvantages. Particularly in the reconstruction of the respiratory tract, precise sewing must be performed in a small space to avoid stenosis of the different diameter of the lumina...

OBJECTIVES: The serological diagnosis of human infection with Angiostrongylus cantonensis remains problematic because there are no commercially available validated tests. Most laboratories use domestically prepared tests such as the enzyme-linked immunosorbent assay (ELISA) or immunoblotting. Since laboratory facilities are not always available in endemic areas, we developed and assessed a rapid lateral flow immunochromatographic assay (AcQuickDx Test) to detect anti-A. cantonensis antibodies in human serum...

Recent studies on face processing and its hemispheric lateralization suggest that inconsistencies in earlier findings might be partially explained by sex differences, as findings from event-related potential studies indicated a more asymmetric functioning of the visual cortex during face encoding in men, whereas women seemed to display a more bilateral activation pattern. The aim of this study was to further investigate the role of sex differences in hemispheric specialization during face recognition. Fifty-four healthy participants (27 females and 27 males) engaged in a familiarity decision task in which famous and unfamiliar faces were presented in a lateralized tachistoscopic fashion with unilateral und bilateral presentation modes and measurement of event-related potentials and behavioral responses...

Every day, people are exposed to images of appetizing foods that can lead to high-calorie intake and contribute to overweight and obesity. Research has documented that manipulating the visual perspective from which eating is viewed helps resist temptation by altering the appraisal of unhealthy foods. However, the neural basis of this effect has not yet been examined using neuroimaging methods. Moreover, it is not known whether the benefits of this strategy can be observed when people, especially overweight, are not explicitly asked to imagine themselves eating...

Attentional bias (sensitization) for negative information was estimated using event-related brain potentials (ERPs). We used a three-stimulus visual oddball paradigm that comprised a small diamond standard stimulus (66.7%), a large diamond target stimulus (16.7%), and deviant word stimuli (16.7%) written in Kanji. Furthermore, half the deviant words were negative emotional words (e.g., destruction or scream) and the others half were neutral words (e.g., structure or range). Healthy participants (N = 26) were instructed to press a button after the target appeared while ignoring the other stimuli...

Binocular depth perception (BDP) is one of the most demanding visual function that involves both dorsal and ventral visual information streams. Substantial research has been conducted on the disruption of BDP in patients with schizophrenia. However, research on first-episode and drug-naive patients with schizophrenia (FEDN) is limited. To assess the BDP of schizophrenia patients while controlling for the effects of antipsychotics and the duration of illness. We investigated BDP in patients with schizophrenia via the Titmus Stereopsis Test in this study, by matching the patients into three groups: FEDN ( n = 17), long duration of illness and medicine treatment (LDMT) ( n = 31) and the healthy control group ( n = 40)...

BACKGROUND AND OBJECTIVES: In periodontitis, the Wnt/β-catenin signaling pathway is related to the metabolism of the alveolar bone; further, extracellular matrix metalloproteinase inducer (EMMPRIN) expression is correlated with matrix metalloproteinases (MMPs) expression and inflammation severity. The aim of this study was to perform a preliminary investigation of the interaction between the Wnt/β-catenin signaling pathway and the EMMPRIN/MMPs route in periodontitis. MATERIAL AND METHODS: Chronic periodontitis and healthy gingival tissues were obtained to detect the expression of Wnt3a, β-catenin, EMMPRIN and MMP-2, 9 by using immunohistochemical analysis...

Background: Severe diminished foot somatosensation, for example, caused by neuropathies and advanced aging, contributes to balance deficits and increased fall risk. However, little is known about somatosensory impairment and functional and subjective balance problems in relatively healthy elderly. Method: Vibration perception thresholds (VPTs) were assessed with a biothesiometer and tactile pressure sensation thresholds (TPSTs) with 20 monofilaments in 34 relatively healthy community-dwelling older adults ( M = 69...

Background: Using conventional visual evoked potentials (VEPs), migraine patients were found to be hyperresponsive to visual stimulus. Considering that a significant portion of neuronal activity is lost for analysis in the averaging process of conventional VEPs, in this study we investigated visual evoked responses of migraine patients and healthy volunteers using a different approach: single trial analysis. This method permits to preserve all stimulus-induced neuronal activations, whether they are synchronized or not...

The role of the hippocampus in spatial navigation and the presence of vestibular responsive neurons in limbic areas are well established from animal experiments. However, hippocampal spatial processing in humans is not fully understood. Here we employed real whole body and head-on-trunk rotations to investigate how vestibular signals, either alone or in combination with neck-proprioceptive stimulation, shape the spatial frame of reference in patients with unilateral hippocampal sclerosis (HS). Patients were asked to point in darkness with a light spot, moved on a cylindrical screen by means of a joystick, into their visual straight ahead direction (VSA), to remember this direction in space and to revert back to this point after the rotations...

Traditional quantitative and qualitative research methods inadequately capture the complexity of patients' daily self-management. Contextual inquiry methodology, using home visits, allows a more in-depth understanding of how patients integrate immunosuppressive medication intake, physical activity and healthy eating in their daily lives, and which difficulties they experience when doing so. This mixed-method study comprised two home visits in 19 purposively selected adult heart, lung, liver and kidney transplant patients, asking them to demonstrate how they implement the aforementioned health behaviours...

As Quantitative Susceptibility Mapping (QSM) is maturing, more clinical applications are being explored. With this comes the question whether QSM is sufficiently robust and reproducible to be directly used in a clinical setting where patients are possibly not cooperative and/or unable to suppress involuntary movements sufficiently.
 Subjects and Methods: Twenty-nine patients with Alzheimer's Disease (AD), 31 patients with Mild Cognitive Impairment (MCI) and 41 healthy controls (HC) were scanned on a 3T scanner, including a multi-echo gradient-echo sequence for QSM and an inversion-prepared segmented gradient-echo sequence (T1-TFE, MPRAGE)...
