Study of fission fragment de-excitation by gamma-ray spectrometry with the EXILL experiment

EPJ Web of Conferences, 2017
A large array of Ge detectors installed at ILL, around a 235U target irradiated with cold neutrons, (EXILL) allowed measurement of prompt gamma-ray cascades occurring in fission fragments with an unambiguous determination of fragments.

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Alpha and spontaneous fission half-lives of /sup 242/Pu [PDF]

, 1977
The alpha and spontaneous fission half-lives of /sup 242/Pu are measured relative to the alpha half-life of /sup 239/Pu. If the alpha half-life of /sup 239/Pu is 24290 +- 70 y, the /sup 242/Pu alpha half-life is (3.736 +- .029) x 10/sup 5/ y and the ...

Genetic risk variants implicate impaired maintenance and repair of periodontal tissues as causal for periodontitis—A synthesis of recent findings

Periodontology 2000, EarlyView.
AbstractPeriodontitis is a complex inflammatory disease in which the host genome, in conjunction with extrinsic factors, determines susceptibility and progression. Genetic predisposition is the strongest risk factor in the first decades of life. As people age, chronic exposure to the periodontal microbiome puts a strain on the proper maintenance of ...

Therapeutic potential of spexin in diabetic neuropathy: Insights from in vitro and in vivo models

Experimental Physiology, EarlyView.
Abstract The present study investigated the therapeutic potential of spexin (SPX) on both in vitro and in vivo models of diabetic neuropathy (DN). A total of 40 male BALB/c mice were randomly allocated into four experimental groups (n = 10 per group): a normoglycaemic control, an untreated DN group and two SPX treatment groups (DN+SPX‐12.5 and DN+SPX ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Investigation of RNA-induced gene silencing in the fission yeast Schizosaccharomyces pombe [PDF]

, 2007
PhDRNA interference (RNAi) is a gene regulating system to which can silence genes at both transcriptional and post-transcriptional levels. In this thesis, a ura4-based RNAi selective assay was developed in the fission yeast Schizosaccharomyces pombe ...

Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Determination of the fast-neutron-induced fission cross-section of 242Pu at nELBE

EPJ Web of Conferences, 2018
The fast-neutron-induced fission cross section of 242Pu was determined in the energy range of 0.5 MeV to 10MeV at the neutron time-of-flight facility nELBE. Using a parallel-plate fission ionization chamber this quantity was measured relative to 235U(n,f)

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

The Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...
