BACKGROUND: Radiotherapy is the most widely used treatment method for treating cancer with or without surgery and chemotherapy. In lung cancer, it is one of the important treatment steps in excising the tumor from the lung tissue; unfortunately, radiation can induce epithelial- mesenchymal transition (EMT), a typical physiological process in which cuboidal shaped epithelial cell loses its phenotype and acquires mesenchymal-like phenotype thus, increases the metastasis progression in the body...

Emerging disease threats like Zika pose a risk to naïve populations. In comparison to chronic diseases, there is scientific uncertainty surrounding emerging diseases because of the lack of medical and public health information available as the threat emerges. Further complicating this are the multiple, diverse channels through which people get information. This article used bivariate and multivariate analysis to first describe the breadth of information sources individuals accessed about the Zika virus, and then describe individuals' primary sources of information for Zika using a nationally representative pooled cross-sectional data set collected at 3 time points in 2016 (N = 3,698)...

The incidence of type-1 Diabetes Mellitus (T1DM) has increased steadily in Kuwait during recent years and it is now considered amongst the high-incidence countries. An interaction between susceptibility genes, immune system mediators and environmental factors predispose susceptible individuals to T1DM. We have determined the prevalence of protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene functional variant (C1858T; R620W, rs2476601), HLA-DQ and DR alleles and three autoantibodies in Kuwaiti children with T1DM to evaluate their impact on genetic predisposition of the disease...

Pericardial diseases are relatively common in clinical practice and encountered in various clinical settings with consequent significant morbidity and mortality. However, the diagnosis as well as management can be complex and challenging, as the clinical presentation is usually non-specific. Therefore, there is an increasing role for cardiac magnetic resonance Imaging (CMR) as an imaging tool to facilitate the diagnosis of pericardial diseases. Herein we describe conventional and unique CMR approaches to provide an increased non-invasive understanding of the pericardium in health and disease including a novel method to diagnose constrictive pericarditis via radio-frequency tissue tagging by defining unique visceral-parietal adherence patterns easily learned by the cardiologist and radiologist...

Fungal polysaccharides are mainly taken orally, so it is very important to study the absorption mechanism of which in vivo for understanding its biological activities. In this work, a polysaccharide fraction (GLP) was purified from G. lucidum by water extraction and alcohol precipitation. Physicochemical characterization indicated that GLP had a molecular weight of 108 kDa and consisted of glucose (35.56%), xylose (40.11%), rhamnose (16.45%) and l-arabinose (7.88%) in a molar radio of 4.51: 5.09: 2.88: 1...

Hereditary leiomyomatosis and renal cell cancer (HLRCC) is a hereditary cancer syndrome characterized by inactivation of the Krebs cycle enzyme fumarate hydratase (FH). HLRCC patients are at a high risk of developing kidney cancer of type 2 papillary morphology that is refractory to current radio-, immuno-, and chemo- therapies. Hence, an effective therapy for this deadly form of cancer is urgently needed. Here we show that FH inactivation (FH-/- ) proves synthetic lethal with inducers of ferroptosis, an iron-dependent and nonapoptotic form of cell death...

OBJECTIVES: The continuous scientific advances against neoplastic diseases affecting all areas of oncology biomedical research. Age is an extremely important factor in cancer development, since the incidence of cancer increases significantly with age. Because of aging of the Italian population, although the incidence is kept constant, the number of cancer diagnosis is inevitably going to increase over time only to increasing age. METHODS: Survival after the diagnosis of cancer is one of the main indicators that allow to evaluate the effectiveness of the health system against the cancer disease...

Intraoperative imaging (IOI) is performed to guide delineation and localization of regions of surgical interest. While oncological surgical planning predominantly utilizes x-ray computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound (US), intraoperative guidance mainly remains on surgeon interpretation and pathology for confirmation. Over the past decades however, intraoperative guidance has evolved significantly with the emergence of several novel imaging technologies, including fluorescence-, Raman, photoacoustic-, and radio-guided approaches...

Background: Canine mastocytomas (mast cell tumors) represent a common malignancy among many dog breeds. A typical treatment strategy for canine mastocytomas includes surgery, chemo- and radio-therapy, although in many cases the therapy fails and the disease progression resumes. New treatment approaches are needed. Aims: The goal of this pilot study was to examine safety and efficacy of oncolytic Sendai virus therapy administered to canine patients with cutaneous or subcutaneous mastocytomas. Materials and Methods: Six canine patients, with variable grades and stages of the disease, received virus therapy, either as a monotherapy, or in combination with surgery...

Radiation exposure severely damages the hematopoietic system. Although several radio-protectors have been proposed to prevent radiation-induced damage, most agents have limited efficacy. In the present study, we investigated whether mesenchymal stem cells (MSCs) could contribute to the expansion of hematopoietic cells and mitigate radiation-induced hematopoietic injury in vitro and in vivo. We found that co-culture with MSCs promoted hematopoietic progenitor/stem cell (HPSCs) maintenance by providing a bone marrow-like microenvironment...

Pipes are one of the key elements in the construction of ships, which usually contain between 15,000 and 40,000 of them. This huge number, as well as the variety of processes that may be performed on a pipe, require rigorous identification, quality assessment and traceability. Traditionally, such tasks have been carried out by using manual procedures and following documentation on paper, which slows down the production processes and reduces the output of a pipe workshop. This article presents a system that allows for identifying and tracking the pipes of a ship through their construction cycle...

INTRODUCTION: Closed flexor tendon rupture after a malunited distal radius fracture is rare and usually becomes apparent early after the fracture. Most cases are accompanied by a severe distal radio-ulnar joint capsule injury, wherein bone protrusion (as a spur) directly stresses the tendons. We experienced a nonspecific flexor tendon rupture associated with an old fracture and the presence of collagen disease. PRESENTATION OF CASE: A 63-year-old woman presented with delayed complete rupture of the flexor digitorum profundus (FDP) of the fifth digit...

PURPOSE: The anaerobic metabolism of glucose by cancer cells, even under well oxygenated conditions, has been documented by Otto Warburg as early as 1927. Micro-environmental hypoxia and intracellular pathways activating the hypoxia-related gene response, shift cancer cell metabolism to anaerobic pathways. In the current review we focus on a major enzyme involved in anaerobic transformation of pyruvate to lactate, namely lactate dehydrogenase 5 (LDH5). CONCLUSIONS: The value of LDH5 as a marker of prognosis of cancer patients, as a predictor of response to radiotherapy and chemotherapy and, finally, as a major target for cancer treatment and radio-sensitization is reported and discussed...

Ravi Pant, Siva Shakthi A, Anjali B Yelikar
Wideband excitation and control of Fano resonance and electromagnetically induced transparency (EIT), both of which rely on coherent interaction between two excitation paths, is challenging. It requires precise control and tuning of interacting resonances or coupling between different resonant structures over a wide frequency range. Gain (Stokes) and absorption (anti-Stokes) resonances associated with the stimulated Brillouin scattering (SBS) process can be excited and controlled over a wide frequency range by tuning the pump frequency, its power and profile...

The papillary tumor of the pineal region (PTPR) is a rare grade II-III pineal lesion with peculiar histologic and immunohistochemical features. These tumors mostly occur in adults, rarely in children (19 cases reported up to now). We present a 3-year-old boy who was re-operated for a recurrent PTPR (grade II). The gross total resection of the lesion, through an occipital interhemispheric approach in sitting position, was followed by adjuvant radiochemotherapy. Histological examination revealed tumor progression (grade III), and the MIB-1 proliferation index was higher than 25%...

C Eichler, J R Petta
We realize a superconducting circuit analog of the generic cavity-optomechanical Hamiltonian by longitudinally coupling two superconducting resonators, which are an order of magnitude different in frequency. We achieve longitudinal coupling by embedding a superconducting quantum interference device into a high frequency resonator, making its resonance frequency depend on the zero point current fluctuations of a nearby low frequency LC resonator. By applying sideband drive fields we enhance the intrinsic coupling strength of about 15 kHz up to 280 kHz by controlling the amplitude of the drive field...
