Late side-effects after curative intent radiotherapy: Identification of hypersensitive patients for personalized strategy.

Radiation therapy undeniably enhances local control and thus improves overall survival in cancer patients. However, some long-term cancer survivors (less than 10%) develop severe late radio-induced toxicities altering their quality of life. Therefore, there is a need to identify patients who are sensitive to those toxicities and who could benefit from adapted care. In this review, we address all available techniques aiming to detect patients' hyper-radiosensitivity and present the scientific rationales these techniques are based on.

Strategy selection: An introduction to the modeling challenge

Modeling the mechanisms that determine how humans and other agents choose among different behavioral and cognitive processes-be they strategies, routines, actions, or operators-represents a paramount theoretical stumbling block across disciplines, ranging from the cognitive and decision sciences to economics, biology, and machine learning. By using the cognitive and decision sciences as a case study, we provide an introduction to what is also known as the strategy selection problem. First, we explain why many researchers assume humans and other animals to come equipped with a repertoire of behavioral and cognitive processes. Second, we expose three descriptive, predictive, and prescriptive challenges that are common to all disciplines which aim to model the choice among these processes. Third, we give an overview of different approaches to strategy selection. These include cost‐benefit, ecological, learning, memory, unified, connectionist, sequential sampling, and maximization approaches. We conclude by pointing to opportunities for future research and by stressing that the selection problem is far from being resolved.

Thrombin-sensitive photodynamic agents: a novel strategy for selective synovectomy in rheumatoid arthritis.

Protease-sensitive macromolecular prodrugs have attracted interest for bio-responsive drug delivery to sites with up-regulated proteolytic activities such as inflammatory or cancerous lesions. Here we report the development of a novel polymeric photosensitizer prodrug (T-PS) to target thrombin, a protease up-regulated in synovial tissues of rheumatoid arthritis (RA) patients, for minimally invasive photodynamic synovectomy. In T-PS, multiple photosensitizer units are tethered to a polymeric backbone via short, thrombin-cleavable peptide linkers. Photoactivity of the prodrug is efficiently impaired due to energy transfer between neighbouring photosensitizer units. T-PS activation by exogenous and endogenous thrombin induced an increase in fluorescence emission by a factor of 16 after in vitro digestion and a selective fluorescence enhancement in arthritic lesions in vivo, in a collagen-induced arthritis mouse model. In vitro studies on primary human synoviocytes showed a phototoxic effect only after enzymatic digestion of the prodrug and light irradiation, thus demonstrating the functionality of T-PS induced PDT. The developed photosensitizer prodrugs combine the passive targeting capacity of macromolecular drug delivery systems with site-selective photosensitizer release and activation. They illuminate lesions with pathologically enhanced proteolytic activity and induce cell death, subsequent to irradiation.

Réduction de la consommation de sel: une mesure importante de santé publique en Suisse. [Reducing dietary salt intake: an important public health strategy in Switzerland]

La consommation actuelle de sel (chlorure de sodium) est très supérieure aux besoins physiologiques (1,5 g par jour, soit environ 550 mg par jour de sodium) dans la plupart des pays (> 8 g par jour). Les principales sources de sel sont les pains, les fromages, les produits dérivés de la viande et les plats précuisinés. En moyenne, une consommation élevée de sel est associée à une pression artérielle plus élevée. En Suisse, un adulte sur trois souffre d'hypertension artérielle. La moitié des accidents vasculaires cérébraux et des maladies cardiaques ischémiques sont attribuables à une pression artérielle trop élevée. L'Office fédéral de la santé publique conduit actuellement une stratégie visant à diminuer la consommation de sel dans la population suisse à moins de 5 g par jour sur le long terme (Salz Strategie 2008-2012). [Abstract] Current dietary salt (sodium chloride) intake largely exceeds physiological needs (about 1.5 g salt per day, or 550 mg sodium per day) in most countries (> 8 g salt per day). The main sources of dietar salt intake are breads, cheeses, products derived from meat and ready-to-eat meals. On average, a high-salt diet is associated with higher blood pressure levels. In Switzerland, one out of three adults suffers from arterial hypertension. Half of cerebrovascular events and ischaemic cardiac events are attributable to elevated blood pressure. The Swiss Federal Office of Public Health is currently running a strategy aiming at reducing dietary salt intake in the Swiss population to less than 5 g per day on the long run (Salz Strategie 2008-2012).

Iowa Strategy for Homeland Security and Emergency Management 2015-2017, October 1, 2014

Address sustainability in all efforts. Sustainability should be at the core of all levels of homeland security and emergency management effort in Iowa. Capabilities need to be built for the long term, and without a sustainability plan in place, projects can quickly deplete uncertain levels of funding. Utilize an all-hazards methodology. Developing capabilities that are effective during a variety of disaster and emergency scenarios represents sound planning and resource management. Enhance capabilities through joint planning, training and exercise. Effective capabilities developed through coordinated planning efforts and an ongoing joint training and exercising program to ensure substantiate of prepared response. Utilize a collaborative approach to build capability. We will utilize whatever partnerships are necessary to build capability in the most effective manner possible. Regional partnerships have been, and will continue to be, in the forefront of the State of Iowa’s efforts to build and enhance capability. Enhance statewide capabilities. Whenever possible, we will identify and augment existing resources to provide statewide capability during a disaster or terrorist attack. Awareness, outreach and education. Open communication is critical to the success of any initiative. All projects implemented will have awareness, education and outreach components to ensure that all stakeholders are informed as to their responsibilities, capabilities and access. Information sharing and a common operating picture. The timely exchange of critical/actionable information is imperative to the success of every operation. The identification of a common operating picture allows decision makers to make informed decisions based on a unified understanding of the events around them.

Sustained NKG2D engagement induces cross-tolerance of multiple distinct NK cell activation pathways

NKG2D is a multisubunit activation receptor that allows natural killer (NK) cells to detect and eliminate stressed, infected, and transformed host cells. However, the chronic exposure of NK cells to cell-bound NKG2D ligands has been shown to impair NKG2D function both in vitro and in vivo. Here we have tested whether continuous NKG2D engagement selectively impacted NKG2D function or whether heterologous NK cell activation pathways were also affected. We found that sustained NKG2D engagement induced cross-tolerization of several unrelated NK cell activation receptors. We show that receptors that activate NK cells via the DAP12/KARAP and DAP10 signaling adaptors, such as murine NKG2D and Ly49D, cross-tolerize preferentially NK cell activation pathways that function independent of DAP10/12, such as antibody-dependent cell-mediated cytotoxicity and missing-self recognition. Conversely, DAP10/12-independent pathways are unable to cross-tolerize unrelated NK cell activation receptors such as NKG2D or Ly49D. These data define a class of NK cell activation receptors that can tolerize mature NK cells. The reversible suppression of the NK cells' cytolytic function probably reduces the NK cells' efficacy to control endogenous and exogenous stress yet may be needed to limit tissue damage

Management Strategy for Iowa’s Water Resources, December 2007

In Iowa, the Department of Natural Resources (DNR)is responsible for regulating water allocation and use through the issuance of water use permits, but improvements are necessary in this process to assure sustainable supplies into the future. In recent years, there have not been resources dedicated at the state level to properly track and assess water quantity issues. Resources for water use and water quantity monitoring (groundwater level and surface gauges) have continued to decline and have resulted in data becoming outdated and in a format that is difficult to analyze in order to make good decisions.

Endosperm genotyping as a strategy to differentiate the allele source in maize heterozygous progeny

The objective of this work was to distinguish the parental source of alleles in heterozygous progeny using semiquantitative polymerase chain reaction (PCR) in maize endosperm. Endosperms derived from direct and reciprocal single-cross hybrids between maize inbred lines L3 and L1113-01 were genotyped by semiquantitative PCR methodology (SQ-PCR) using fluorescent microsatellite primers. The amplification products were evaluated by the ratios of fluorescence intensity (RFI), calculated between the peaks corresponding to the alleles derived from each parental line. Based on the statistically significant contrast between RFI mean values of direct and reciprocal single-cross hybrids, it was possible to distinguish the number of alleles received from each parental line and, ultimately, to determine the origin of the alleles of each cross. Thus, endosperm genotyping using SQ-PCR is a promising strategy to map QTL in maize outbred populations.
