Novel time-synchronized immune-guided partial tumor irradiation: Proof of principle trial.

Radiother Oncol

October 2024

KABEG Klinikum Klagenfurt, Institute of Radiation Oncology, Feschnigstraße 11 9020, Klagenfurt am Wörthersee, Austria.

Background And Purpose: Radiotherapy for bulky tumors often results in palliation with suboptimal outcomes. The prognosis is worsened by immunosuppression caused by radio-chemotherapy, negatively impacting on survival. Novel Partial Tumor Irradiation (PTI) was designed to spare the Peritumoral Immune Microenvironment (PIM) and to be delivered synchronously with immune activity peaks, thus enhancing both local and distant tumor control through immunostimulation.

Background: Radiotherapy-induced lymphopenia may be limiting the success of therapy and could also negatively affect the ability of immune system in mediating the bystander (BE) and abscopal effects (AE). A novel SBRT-based PArtial Tumor irradiation of HYpoxic clonogenic cells (SBRT-PATHY) for induction of the tumoricidal BE and AE by sparing the peritumoral immune microenvironment and regional circulating lymphocytes has been developed to enhance the radiotherapy therapeutic ratio of advanced lung cancer. The aim of this retrospective review of prospectively collected mono-institutional phase 2 study was to compare the outcomes between unconventional SBRT-PATHY and standard of care in unresectable stage IIIB/IV bulky NSCLC.

The physics of open systems for the simulation of complex molecular environments in soft matter.

Soft Matter

March 2019

Instituto per le Applicazioni del Calcolo, Consiglio Nazionale delle Ricerche, and Universita' La Sapienza, Rome, Italy.

Molecular dynamics (MD) has become one of the most powerful tools of investigation in soft matter. Despite such success, simulations of large molecular environments are mostly run using the approximation of closed systems without the possibility of exchange of matter. Due to the molecular complexity of soft matter systems, an optimal simulation strategy would require the application of concurrent multiscale resolution approaches such that each part of a large system can be considered as an open subsystem at a high resolution embedded in a large coarser reservoir of energy and particles.

The Challenges of Nutritional Assessment in Cirrhosis.

Curr Nutr Rep

September 2017

Department of Internal Medicine, Division of Gastroenterology and Hepatology, University of California Davis, Sacramento, California.

Purpose Of Review: Nutritional status in patients with cirrhosis is very frequently associated with macro- and micronutrient deficiencies. Cirrhosis itself is the cause of malnutrition and nutritional deficiencies but these conditions have to be identified and addressed properly as they can worsen the prognosis of cirrhosis. The goals of this review are to 1) identify and describe the challenges associated with nutritional assessment in cirrhosis and 2) describe recent advancements when using clinical, laboratory, and instrumental tools in the evaluation of malnourished patients with liver diseases.

Article Synopsis
  • The scalar field responsible for cosmological inflation is linked to Weyl's differential geometry and the concept of parallel displacement in curved space-time.
  • Within this framework, the electroweak theory of leptons is analyzed, revealing connections between elementary particles' properties and dark energy through a Higgs mechanism and an effective cosmological potential.
  • The theory also presents a new approach to the mass of the Higgs boson related to the cosmological constant, and proposes a candidate for dark matter while addressing the "Cosmological Constant Paradox" in quantum field theory.

Genome-wide association studies (GWAS) test hundreds of thousands of single-nucleotide polymorphisms (SNPs) for association to a trait, treating each marker equally and ignoring prior evidence of association to specific regions. Typically, promising regions are selected for further investigation based on p-values obtained from simple tests of association. However, loci that exert only a weak, low-penetrant role on the trait, producing modest evidence of association, are not detectable in the context of a GWAS.

We investigate the collective thermal diffusion of silica charged spheres in Sulpho-Rhodamine B/water solution at different concentrations by measuring time-dependent thermal and Soret lensings. We show a significant concentration-dependence of the thermal diffusion coefficient D(T), not previously reported. Moreover, the results clearly show that both mass diffusion and Soret coefficient are collective quantities being strongly dependent on the particles' packing fraction.

[The renal pathology in light chain deposition disease].

G Ital Nefrol

April 2006

Dipartimento di Medicina Sperimentale e Patologia, Universita' La Sapienza, Roma.

Light Chain Deposition Disease (LCDD) is a relatively frequent renal disease associated with dysproteinemia. Although the light chain deposits can be widespread, the kidney is the most frequently involved organ, and renal involvement can dominate the clinical condition. The morphological features of LCDD can be recognized by light microscopy; however, the diagnosis can be made certain only by immunofluorescence microscopy, using antisera to kappa and lambda chains, and by electron microscopy.
