As primary duodenal adenocarcinoma is rare, the prognostic factors of this disease remain insufficiently explored, especially in China. We identified postoperative duodenal adenocarcinoma patients at a Chinese double-center (from 2006 to 2016) or who were registered with the Surveillance, Epidemiology, and End Results (SEER) database (from 2004 to 2014). Clinicopathological features and significant prognostic factors for cancer-specific survival (CSS) were reviewed and analyzed by using univariate and multivariate Cox proportional hazards regression...

The cardiovascular diseases occupy a leading place in the structure of overall morbidity affecting the population not only of Russia but also of the majority of the developed countries throughout the world; they thus impose the heavy social and economic burden on both the public healthcare services and the modern society in general. At the same time, systemic atherosclerosis is considered to be one of the most common, severe, and life-threatening condition. Despite the presence of a large number of pharmaceutical and surgical methods for the treatment of this pathology, they are not infrequently lacking the desired effectiveness...

While spinal cord deformation is thought to be a predictor of spinal cord injury severity, few researchers have directly investigated the dynamic cord deformation or distribution of the deformation between white and grey matter of the in vivo spinal cord during impact. This knowledge would help to establish correlations among impact parameters, internal spinal cord deformation, and histological and functional outcomes. Relying on surface deformations alone may not be a sufficient representation of spinal cord deformation...

Electrical neuromodulation of spinal networks improves the control of movement of the paralyzed limbs after spinal cord injury (SCI). However, the potential of non-invasive spinal stimulation to facilitate postural trunk control during sitting in humans with SCI has not been investigated. We hypothesized that transcutaneous electrical stimulation of the lumbosacral enlargement can improve trunk posture. Eight participants with non-progressive SCI, C3-T9, AIS A or C, performed different motor tasks during sitting...

Over the last decades, the spin coating (SC) technique has been widely used to prepare thin films of various materials in liquid phase on arbitrary substrates. The technique simply relies on centrifugal force to spread a coating solution radially outwards over the substrate. This mechanism works fairly well for solutions with low surface tension to form thin films of reasonable junctions on smooth substrates. Here, we present a modified SC technique, namely ultrasonic-assisted spin-coating (UASC), to form thin films of coating solution having high surface tension on rough substrates with excellent junctions...

Background: Several medical schools around the world are moving away from isolated, locally developed in-house assessments to the introduction of external examinations into their curriculum. Although the objective varies, it is typically done to evaluate, audit, and compare students' performance to international standards. Similarly, the International Foundations of Medicine-Clinical Sciences Examination (IFOM-CSE) was introduced in the College of Medicine at the University of Sharjah as an external assessment criterion in addition to the existing in-house assessments...

The field of marriage and family therapy has historically focused on dynamics within family systems, and at times the role of social and cultural factors external to the family. To date, however, little scholarship has examined how therapists themselves are embedded within a mental healthcare system. The purpose of this article is to demonstrate how structural components of the mental healthcare system shape the practice of therapy. We draw from the field of medical sociology to illustrate how three dominant structures-managed care, diagnosis, and evidence-based models-are intertwining and mutually reinforcing systems that have significant and long-term implications for systemic therapists and researchers...

In this report, we investigate on a biomimetic model of a H-bonded TyrZ/His190 pair covalently attached to a porphyrin sensitizer. Laser flash photolysis in presence of an external electron acceptor reveals the need of water molecules to unlock the light-induced oxidation of the phenol through an intramolecular pathway. Kinetics monitoring encompasses two fast phases with distinct spectral properties. The first phase is related to one-electron transfer from the phenol to the porphyrin radical cation coupled with a domino two-proton transfer leading to the ejection of a proton from the imidazole-phenol pair...

The purpose of the study was to predict young children's shyness from both internal/biological (i.e., resting respiratory sinus arrhythmia; RSA) and external (i.e., neighborhood quality) factors. Participants were 180 children at 42 (Time 1; T1), 72 (T2), and 84 (T3) months of age. RSA data were obtained at T1 during a neutral film in the laboratory. Mothers reported perceived neighborhood quality at T2 and children's dispositional shyness at T1 and T3. Path analyses indicated that resting RSA interacted with neighborhood quality to predict T3 shyness, even after controlling for earlier family income and T1 shyness...

Halcyon™ is a single-energy (6 MV-FFF), bore-enclosed linear accelerator. Patient setup is performed by first aligning to external lasers mounted to the front of the bore, and then loading to isocenter through pre-defined couch shifts. There is no light field, optical distance indicator or front pointer mechanism, so positioning is verified through MV imaging with kV imaging scheduled to become available in the future. TG-51 reference dosimetry was successfully performed for Halcyon™ in this imaging-based setup paradigm...
