Lógicas da antropotecnia: mensuração do homem e bio-sociologia (1860-1920)

open access: yesRevista Brasileira de História, 2001
A antropometria é um método estatístico de análise do corpo humano criado por volta de 1850 para precisar o lugar do homem na natureza e definir os caracteres das raças humanas. Ela foi rapidamente utilizada para apreciar os fatores "biossociológicos" na

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

open access: yesFEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Scientific opinion on the pest categorisation of Verticillium dahliae Kleb

open access: yesEFSA Journal, 2014
The European Commission requested the EFSA Panel on Plant Health to perform a pest categorisation of Verticillium dahliae Kleb., the fungal pathogen responsible for many Verticillium wilt diseases. V.

An unexpected alternative viologen electron mediator site in tungsten‐containing formate dehydrogenase

open access: yesFEBS Letters, EarlyView.
An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Políticas del conocimiento: los silencios de los obstetras mexicanos sobre las razas y los sexos, fines del siglo XIX

open access: yesNuevo mundo - Mundos Nuevos, 2011
I have found that in the mid-nineteenth Century Mexico, the notions of race and sex became objects for science and favored the production of medical knowledge, and so it happened with obstetrics.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Race-specific leaf and root resistance of winter oilseed rape (Brassica napus L.) to Xanthomonas campestris pv. campestris

open access: yesSiberian Journal of Life Sciences and Agriculture
Background. Researchers from France, Serbia, and Russia have reported the spread of Black Rot in winter rape crop. The cultivation of resistant varieties and hybrids is considered to be the most effective method of reducing the economic damage caused by ...
