: Ameloblastoma is the most common benign odontogenic tumor of the jaw, and expansional growth of a huge untreated ameloblastoma can result in disturbances in facial aesthetics and function, such as difficulty with mouth opening, swallowing, chewing, breathing, neurologic deficits, and pathologic fractures. Radical wide resection with safety margins and subsequent reconstruction is generally recommended. A fibular free flap (FFF) is commonly used to reconstruct the mandible in order to adequately restore both aesthetic appearance and function...

The photophysical properties of a push-pull dye and the dynamics of electron transfer across a dye and ZnO quantum dot (QD) interface have been studied using a combination of steady-state, time-resolved fluorescence and femtosecond transient absorption (TA) spectroscopies. Spectroscopic measurements, along with quantum chemical calculations, provide evidence for the photoinduced intramolecular charge transfer (ICT) in a donor-π-acceptor dye. Wavelength dependent fluorescence decay of the dye infers the solvent relaxation of the ICT state...

This study investigated the feasibility of predicting intrinsically caused trips (ICTs) in individuals with stroke. Gait kinematics collected from twelve individuals with chronic stroke, who demonstrated ICTs in treadmill walking, were analyzed. A prediction algorithm based on the outlier principle was employed. Sequential forward selection (SFS) and minimum-redundancy- maximum-relevance (mRMR) were used separately to identify the precursors for accurate ICT prediction. The results showed that it was feasible to predict ICTs around 50- 260ms before ICTs occurred in the swing phase by monitoring lower limb kinematics during the preceding stance phase...

BACKGROUND: Hyperthermic isolated limb perfusion is used to treat irresectable extremity malignancies. It is based on the following principle - the perfusion of the extremity is isolated from systemic circulation and connected to an extra-corporal circuit via which a very high concentration of a chemotherapeutic agent is administered into the blood compartment of the extremity. In some cases, treatment efficiency can be improved using tasonermin (a TNF-α agent). By itself, tasonermin can cause severe health complications in patients if leakage into systemic circulation results in a level that exceeds the maximally tolerated dose...

BACKGROUND: Malignant melanoma is one of the most aggressive types of cancers. Melanoma is derived from pigment-producing cells, melanocytes, which are characterized by a specific survival mechanism. Microphthalmia-associated transcription factor (MITF-M) plays a role in the metabolism of melanoma and is involved in the regulation of the expression of multiple genes mediating processes such as melanogenesis, proliferation, differentiation, and melanocyte survival. The expression of this transcription factor in melanocytes is activated by several signaling pathways, and reduced expression or function of MITF-M can cause the dysregulation of anti-apoptotic mechanisms...

High-dose chemotherapy with autologous stem cell transplantation remains the current standard of treatment for young patients with Hodgkin lymphoma in first relapse or in those who are refractory to first-line treatment. The most important prognostic factors in relapses are clinical stage IV, poor performance status, bulky mass, and less than partial remission after salvage chemotherapy. Standard salvage chemotherapy in relapse before autologous transplantation has not been defined; however, DHAP and ICE are most frequently used in this setting...

BACKGROUND: Prostate cancer (PC) constitutes a heterogeneous group of diseases with high prevalence rates that are still increasing, particularly in western countries. Since 1980, prostate specific antigen (PSA) and other diagnostic approaches have been used for PC screening; however, some of these approaches are often deemed painful and cause invasive damage of tissue. Therefore, molecular approaches to PC diagnosis are attracting increasing attention, potentially providing patients with less stressful situations and providing better diagnoses and even prognostic information...

Over the past couple of decades, coordination-driven self-assembly has evolved as a broad multidisciplinary domain that not only covers the syntheses of aesthetically pleasing supramolecular architectures but also emerges as a method to form new optical materials, chemical sensors, theranostic agents, and compounds with light-harvesting and emissive properties. The majority of these applications depend upon investigations that reveal the photophysical nature and electronic structure of supramolecular coordination complexes (SCCs), including two-dimensional (2D) metallacycles and three-dimensional (3D) metallacages...

Based on the demographic changes and the rapid increase of older population in Europe, major challenges are expected to rise, both in the economy as well as the society, whether the dominant care model for supporting elderly in living independently at home continues to rely on informal and formal caregivers' assistance. To respond to the above challenges, assistive technologies are called to develop Information and Communication Technology (ICT) services for supporting seniors to remain active and independent, for as long as possible, in their chosen home environment...

For centuries, healthcare has been a basic service provided by many governments to their citizens. Over the past few decades, we have witnessed a significant transformation in the quality of healthcare services provided by healthcare organizations and professionals. Recent advances have led to the emergence of Electronic Health (E-health), largely made possible by the massive deployment and adoption of information and communication technologies (ICTs). However, cybercriminals and attackers are exploiting vulnerabilities associated primarily with ICTs, causing data breaches of patients' confidential digital health information records...

Since the mid-2000s, the immunochromatographic card test (ICT), a point-of-care test for detecting Wuchereria bancrofti circulating filarial antigens (CFAs), has been the backbone for mapping and monitoring lymphatic filariasis (LF) worldwide. Recently, there have been instances in which CFA positivity has been associated with Loa loa microfilaremia. Here, we examined the association, at both the community and individual levels, between L. loa and CFA using additional diagnostic tools (quantitative polymerase chain reaction [qPCR], Og4C3 enzyme-linked immunosorbent assay, and IgG4 antibodies to Wb123 assays) to demonstrate the relationship between L...
