Grid stability is being challenged by the increasing integration of power plants with volatile power generation into the energy system. Power supply fluctuations must be compensated by energy system flexibility. The storability of the energy carrier enables biogas plants to generate power flexibly. In this study, the technical and economic effects of providing positive secondary control energy reserves with an Austrian biogas plant were assessed. The plant's main focus lies in biomethane production with the option of heat and power generation through combined heat and power (CHP) units. A detailed simulation model of the investigated biogas plant was developed, which is presented in this work. Ex-post simulations of one year of flexible plant operation were conducted with this model. The findings show that the installed biogas storage capacity is sufficient to provide control energy reserves while simultaneously producing biomethane. Profitability of providing control energy reserves largely depends on the prices at the control energy market and on CHP unit start-up costs. A cost efficiency analysis demonstrated that investing in a hot water tank with a volume of 5 m(3) for short-term heat storage turned out to be economically viable.

1 Objects and their histories: unraveling the “black box”The history of object is a burgeoning field in contemporary historical studies. An object, like a “black box,” contains rich information that holds the secret code for knowledge construction. Object is a multifaceted being, consisting of aspects like technology, institution, human–object relationship, and human–nature interaction. Medicine and food inform sophisticated questions about society and ideology.

What is the rationale for immunotherapies in Parkinsonian syndromes (PS)? PS are neurodegenerative diseases which are clinically characterized by a hypokinetic phenotype in combination with additional motor and non-motor symptoms. One major pathological hallmark of all PS consists of a non-physiological detrimental accumulation of protein aggregates which appear intracellularly in neurons and glial cells but also in the extracellular space (Wong and Krainc, 2017). Depending on the pathogenic protein, PS can be divided into synucleinopathies, characterized by aggregation of the protein alpha-Synuclein (aSyn), and tauopathies, characterized by aggregation of the protein Tau (Levin et al., 2016;Poewe et al., 2017). Clinical syndromes of synucleinopathies include Parkinson’s disease (PD), multiple system atrophy (MSA) and dementia with Lewy bodies, and tauopathies include progressive supranuclear palsy (PSP) and corticobasal degeneration.

To the Editor: In the last decade, next-generation sequencing(NGS)-based molecular profiling has shed light on the molecular landscape of biliary tract cancer(BTC), revealing the presence of several potentially actionable mutations [1]. According to Clinical ***, there are at least 40 phase I to IV ongoing trials aimed at evaluating the role of targeted treatments in BTC, as monotherapy or in combination with other anticancer agents [2]. Early encouraging results have been observed with therapies targeting IDH mutations, FGFR fusions, HER family and, more recently, BRAF mutations [3].

Mitochondrial Transcription Factor A （TFAM） is a nuclear-encoded factor present in mitochondria from allkinds of animals, even with a homologous form in yeast, which has strongly and progressively gained an eminent relevance in the regulation of mitochondrial DNA （mtDNA） functions. This is due to the various functions performed by the protein, which cover a very wide scenario including： replication, transcription, maintenance and eventually repair of mtDNA molecules. In consideration of so many different roles it plays, it can be understood there is a deep interest in its regulation of expression and activity as well as its eventual involvement in pathologies related to a decreased functionality/presence of the mitochondrial genome and the consequences of TFAM induced overexpression.
