BACKGROUND: Standard cone-beam computed tomography (CBCT) involves the acquisition of at least 360 projections rotating through 360 degrees. Nevertheless, there are cases in which only a few projections can be taken in a limited angular span, such as during surgery, where rotation of the source-detector pair is limited to less than 180 degrees. Reconstruction of limited data with the conventional method proposed by Feldkamp, Davis and Kress (FDK) results in severe artifacts. Iterative methods may compensate for the lack of data by including additional prior information, although they imply a high computational burden and memory consumption...

Glioblastoma multiforme (GBM) is one of the most aggressive brain tumors. GBM represents >50% of primary tumors of the nervous system and ~20% of intracranial neoplasms. Standard treatment involves surgery, radiation and chemotherapy. However, the prognosis of GBM is usually poor, with a median survival of 15 months. Resistance of GBM to treatment can be explained by the presence of cancer stem cells (CSCs) among the GBM cell population. At present, there are no effective therapeutic strategies for the elimination of CSCs...

According to recent research, nanotechnology based on quantum dots (QDs) has been widely applied in the field of bioimaging, drug delivery, and drug analysis. Therefore, it has become one of the major forces driving basic and applied research. The application of nanotechnology in bioimaging has been of concern. Through in vitro labeling, it was found that luminescent QDs possess many properties such as narrow emission, broad UV excitation, bright fluorescence, and high photostability. The QDs also show great potential in whole-body imaging...

Background: Neurosurgeons are exposed to unavoidable distractions in their natural operating environment. Distractions can affect both the surgeon's concentration and the safety and duration of the surgery. Such distraction can be studied by applying a simultaneous cognitive task during a surgical procedure. Methods: We used a previously described cognitive task: a forward (DF) and backward digit (DB) repetition task to interfere with the surgeon's attention during a training bypass...

During the last two decades, minimally invasive techniques and instruments in spine surgery have undergone serious development in all fields. Specific advantages of these minimally invasive methods have put them forward in spine surgery in recent times. Preservation of important anatomical structures of the spine is a major factor for the evolution of these procedures. The lower prevalence of complications and faster rehabilitation of patients are some of the advantages of minimally invasive spine surgery (MISS)...

Background: Complications frequently occur in patients with spinal cord injury (SCI) during acute care or rehabilitation and have an impact on rehabilitation outcomes. Purpose: The aim of this study was to determine the occurrence and risk factors for complications in recently injured SCI patients. Methods : Two hundred fifty patients with traumatic injuries with and without complications were counted for the following dichotomous parameters: gender (male/female), associated lesions (presence/absence), surgery (yes/no), American Spinal Injury Association Impairment Scale (AIS) grade (A/other categories), lesion level (lumbar/other levels), and lesion-to-admission time (less than/longer than 1 month)...

5-fluorouracil (5-FU) based adjutant chemotherapy (ACT) is widely used for the treatment of colon cancer. Colon cancer with different primary tumor locations are clinically and molecularly distinct, implied the distinction in response to 5-FU-based ACT. In this work, using 69 and 133 samples of patients with stage II-III right-sided and left-side colon cancer (RCC and LCC) treated with post-surgery 5-FU-based ACT, we pre-selected gene pairs whose relative expression orderings (REOs) were significantly correlated with the DFS of patients by univariate Cox proportional hazards model...

Stroke is considered a major cause of global morbidity. Currently, there are no effective treatments for post-stroke cognitive impairment. Enriched environment (EE) has been brought forward as a preconditioning method to induce cerebral tolerance in an ischemic event. However, the subjacent mechanisms involved in this tolerance are not yet clear. Herein we aimed to identify the mechanisms of neuroprotection triggered by EE preconditioning in a murine model of ischemic stroke. In order to do so, C57Bl/6 mice were kept for five weeks either in EE or in standard environment (SC) prior to ischemic injury through bilateral carotid occlusion (BCCAo) or sham surgery...

Colorectal cancer is the third most common malignant tumor among men, and the second most common malignant tumor among women worldwide. As one of the most common malignant tumor, colorectal cancer has a great threat to the health of people. Although the development of radiotherapy and chemotherapy could improve the prognosis of colorectal cancer, surgery, the complete resection of the tumor, remains the only chance for the cure of this disease. Over the past hundred years, surgical oncology went in the direction of protecting organ function and improving quality of life...
