Conservative Progress [PDF]

open access: yesThe Boston Medical and Surgical Journal, 1884
The advance of science is hindered not more by obstinacy than by fickleness. The skepticism which uses an honest crucible is a blessing; the skepticism which wields a club, and smashes old things indiscriminately because they are ancient, is a curse. Underneath its destructive malice is often a credulous and craven tenderness for anything which is new.

Insights into a long life without cancer: The case of the bowhead whale

open access: yesMolecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Art and environment as media for ecosustainability, ethics and aesthetics

open access: yesConservation Science in Cultural Heritage, 2012
“Art, both in a strict sense, but also in a broader sense, that is to say environmental and cultural heritage – considering, as it correctly should be, the environment with its individual compartments of air, soil and water – is indissolubly linked to ...

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

SIRT4 positively regulates autophagy via ULK1, but independently of HDAC6 and OPA1

open access: yesFEBS Open Bio, EarlyView.
Cells expressing SIRT4 (H161Y), a catalytically inactive mutant of the sirtuin SIRT4, fail to upregulate LC3B‐II and exhibit a reduced autophagic flux under stress conditions. Interestingly, SIRT4(H161Y) promotes phosphorylation of ULK1 at S638 and S758 that are associated with inhibition of autophagy initiation.

A note from the restoration world: the Raffaello completed?

open access: yesConservation Science in Cultural Heritage, 2002
History of a restoration work that had opened the way to a new, fascinating attribution hypothesis for a drawing that was considered a Giulio Romano’s work and today it is considered a Raffaello’s work, with a subsequently partial intervention of his ...

FGFR Like1 drives esophageal cancer progression via EMT, PI3K/Akt, and notch signalling: insights from clinical data and next‐generation sequencing analysis

open access: yesFEBS Open Bio, EarlyView.
Clinical analysis reveals significant dysregulation of FGFRL1 in esophageal cancer (EC) patients. RNAi‐coupled next‐generation sequencing (NGS) and in vitro study reveal FGFRL1‐mediated EC progression via EMT, PI3K/Akt, and Notch pathways. Functional assays confirm its role in tumor growth, migration, and invasion.

Randomness Conservation over Algorithms [PDF]

open access: yes, 2013
Current discrete randomness and information conservation inequalities are over total recursive functions, i.e. restricted to deterministic processing. This restriction implies that an algorithm can break algorithmic randomness conservation inequalities ...

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

open access: yesFEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...
