BACKGROUND Stereotactic ablative body radiation (SABR) is a novel and sophisticated radiation modality that involves the irradiation of extracranial tumors through precise and very high doses in patients with oligometastatic lung disease and primary lung tumors. CASE PRESENTATION A 52-year-old female with subclinical idiopathic interstitial lung disease (ILD) and oligometastatic lung disease ...

Radiotherapy is commonly planned on the basis of physical dose received by the tumour and surrounding normal tissue, with margins added to address the possibility of geometric miss. However, recent experimental evidence suggests that intercellular signalling results in a given cell's survival also depending on the dose received by neighbouring cells. A model of radiation-induced cell killing an...

the variations of glucose 6-phosphate dehydrogenase (g6pd) activity in different brain regions of normal, hypo- and hyperthyroid rats were investigated. hypo- and hyperthyrodism were experimentaly induced by administration of methimazol and liothyronine, respectively. in normal rats, midbrain had the minimum (70 mu/mg) and cerebral cortex the maximum (349 mu/mg) g6pd activity. hyperthyrodism in...

In this paper we examine the use of hypotheticals as a heuristic device to assist a case-based reasoner test the strengths, weaknesses, and ramifications of an analysis or argument by exploring and augmenting the space of known cases and indirectly, the at tendant spaces of doctrine and argument. Our program, HYPO, works in the task domain of the law, particularly, the area of trade secret prot...

he proportion of survival of out-of-hospital cardiac arrest is improving with increased implementation of prompt bystander cardiopulmonary resuscitation (CPR) and early defibrillation; however, the neurologically intact survival for patients of out-of-hospital cardiac arrest still remains low worldwide. Furthermore, development of support measures such as pharmacological circulatory support for...

OBJECTIVES The aim of this study was to establish a new, dynamic 3-dimensional cardiac magnetic resonance (3D-CMR) perfusion scan technique exploiting data correlation in k-space and time with sensitivity-encoding and to determine its value for the detection of coronary artery disease (CAD) and volumetry of myocardial hypoenhancement (VOLUME(hypo)) before and after percutaneous coronary stentin...

We investigated the effect of thyroid hormone status on renal handing of Ca2+. Further, like kinetics of Ca2+ transport across brush-border membrane (BBM) and basolateral membrane (BLM) of renal epithelial cells was carried out. FE(Ca) was decreased in hyperthyroid (Hyper-T) rats and increased in hypothyroid (Hypo-T) rats as compared to euthyroid (Eu-T) rats. Ca2+ uptake into renal brush-border...

High-throughput RNA sequencing was used to compare expression profiles in two Arctic charr (Salvelinus alpinus) families post-seawater exposure to identify genes and biological processes involved in hypo-osmoregulation and regulation of salinity tolerance. To further understand the genetic architecture of hypo-osmoregulation, the genomic organization of differentially expressed (DE) genes was a...

Radioresistance is still an emerging problem for radiotherapy of oral cancer. Aberrant epigenetic alterations play an important role in cancer development, yet the role of such alterations in radioresistance of oral cancer is not fully explored. Using a methylation microarray, we identified promoter hypermethylation of FHIT (fragile histidine triad) in radioresistant OML1-R cells, established f...

Hypo-fractionated stereotactic body radiation therapy (SBRT) employs precisely-conforming high-level radiation dose delivery to improve tumor control probabilities and sparing of healthy tissue. However, the delivery precision and conformity of SBRT renders dose accumulation particularly susceptible to organ motion, and respiratory-induced motion in the abdomen may result in significant displac...
