Filter by:Studies have reported that tumors with the same immunogenic mutations may induce T cell receptor (TCR) domains with similar antigen recognition functions. By assembling the complementarity-determining region 3 (CDR3) of TCRs from RNA-seq data and correlating them with 9142 samples from TCGA data, an in-depth analysis of the TCR pool in the tumor microenvironment found a strong correlation between the CDR3 sequences of tumor-infiltrating T cells and tumor mutation burden. Fairfax et al. found that in patients responding to tumor immunotherapy, the TCR immune pool of CD8+ T cells produces many clones with extremely high abundance (exceeding 0.5%) . Cader et al. also found significant changes in the TCR immune pool of patients with Hodgkin's lymphoma responding to PD-1 tumor immunotherapy. Based on these theoretical foundations, evaluating the dynamic changes of the TCR immune pool is expected to be used to analyze the immune characteristics and changes in diseases such as malignant tumors.
This study aims to evaluate the sensory processing processes of elderly adults who have undergone fall-related hip fracture surgery in the last 6 months, according to different patterns, and to examine the relationship between physical performance, fall risk, fear of falling, and depression parameters that may be related to sensory processing.
Due to the impracticality of accessing the gold standard test devices, researchers have developed easy-to-use and cost-effective smartphone applications that do not require expert knowledge, and these applications have been used to measure different motor abilities. Smartphone applications such as CODtimer, Stopwatch Movie watch, and Seconds Count are used to evaluate the ability to change direction within these biomotor features. However, the validity and reliability of these applications are the subjects of research.
Interoceptive complex sensations and fear beliefs resulting from cardiac risk factors or cardiovascular disease can further increase one's awareness and attention to bodily situations and cause differences in the interpretation of somatic sensations. These intraceptive somatic sensations may be the underlying factors for participation in exercise and compliance with exercise programs No Turkish questionnaire evaluating unpleasant sensations (Exercise sensitivity) was found. Exercise Sensitivity Questionnaire, which we planned to validate in our study, is a questionnaire developed by Samantha Farris et al. in 2020 to measure anxiety, exercise avoidance behavior and exercise sensitivity, which are frequently observed in individuals with heart disease.
Combining genomics and imageomics to predict the sensitivity of neoadjuvant pemetrexed and cisplatin chemotherapy in patients with lung adenocarcinoma
Composite is one of the common aesthetic restorations used in the dentistry. With the advancements in the biomaterials the application of the composites has broadened. However due to various factors the composites are associated with dental sensitivity. Hence in our study we evaluate and compare the effectiveness of three desensitizing agents in reducing the post-treatment sensitivity for class I composite restoration.
The Amadeo® Manual Robotic System (Tyromotion GmbH, Graz, Austria) is designed for rehabilitative treatment of the hand and fingers providing robot-assisted exercise for the finger flexors and extensors. This system has a controlled position, active, active-assisted and passive exercise mode, it also allows isometric exercises with visual feedback provided during computerized games that emphasize flexion and extension. Another of the functions that this device presents and that differentiates it from other handheld robotic systems is its vibration function. Through sensors that are placed on the fingertips, providing a vibratory proprioceptive stimulus of different frequencies. Currently, there are no published trials on the efficacy of the vibration of this device and its consequent improvement in the sensitivity and functionality of patients with hemiparesis after stroke. Investigations have been conducted in patients with peripheral lesions and in the healthy population. A preliminary study with monkeys demonstrated that the frequency of the vibration presents better results when the muscle stretch receptors are driven by a high frequency vibration, activating the neurons corresponding to the motor cortex and in the 3rd primary sensory area. More recent studies have shown the efficacy of focal vibratory stimulation applied to the wrist and forearm muscles, specifically the application to the tendon of the stimulated muscle. Regarding the most appropriate form of stimulation, the most important determining factors to highlight are the frequency of application, the duration and intensity and the time of application. The mechanism of action of local muscle vibration is to stimulate various receptors. Meissner corpuscles respond best around 40 Hz, while Vater-Pacini corpuscles around 100 Hz. Together, they are also known as rapidly adapting cutaneous receptors. In contrast, Merkel-Ranvier cells and Ruffini corpuscles are called slow-adapting and classically described as sensitive to sustained pressure. That is why authors of different studies have focused on high frequency vibration of 300 Hz, for 30 minutes. 3 times per week. The duration of vibratory stimulation, different studies show the effects of vibration and changes in the cortex after performing the treatment constantly, for about ten days, intensively three to four days a week, observing long-term changes in terms on cortical excitability.
The study applies the Sluggishness, Assistance in walking, Rising from a chair, Climb stairs, Falls (SARC-F) questionnaire in older patients hospitalized in an acute care geriatric unit and aims to determine its performance indicators to screen for sarcopenia according to the revised European Consensus on definition and diagnosis (EWGSOP2) within this population
Stereotactic radiation therapy is an important and common method of treating brain metastases in patients with malignant disease. Today, however, there are no methods available to determine the metastasis' radiation sensitivity in advance and treatment responses can only be seen by changing of the size of the metastasis on conventional X-ray examinations, computed tomography (CT) and magnetic resonance imaging (MRI). Changes in the size of the metastases is something that is often seen weeks / months after treatment is completed. At Lund University Hospital, a new imaging technique, diffusional variance decomposition (DIVIDE), has now been developed. With this technique, the scatter in isotropic and anisotropic diffusion can be measured for each measuring point, which provides significantly more information about the properties of the tissue compared to current methods.
Malaria, schistosomiasis and ancylostomiasis are three parasitic diseases which affect hundreds of millions of people and are an important cause of global mortality and morbidity. For the control of these poverty related parasitic diseases, and to complement chemotherapeutic strategies, accurate and accessible diagnostic procedures play a crucial role. In recent years, innovative smart mobile technologies have been applied for detection and identification of cultured parasite species, which is basically based on sample imaging and parasite morphology identification. Promising advances have been made with this technology and coupled with its small size, low cost and easy to manipulate, makes it suitable for point of care diagnostics in low resource setting. The aim of the proposed explorative study is to further validate sensitivity and specificity of each of the developed devices, using besides microscopy a range of more advanced reference tests.
