Documentaci??n geom??trica de un yacimiento arqueol??gico de gran extensi??n. El ejemplo de Contrebia Leukade (La Rioja)

[ES] La investigaci??n hist??rica en yacimientos arqueol??gicos de grandes dimensiones, requiere de un soporte gr??fico con base geom??trica en el que puedan ser referenciados los hallazgos, reflejadas las ??pocas hist??ricas, planificadas las intervenciones, dise??adas las soluciones constructivas o restauradoras, definidas las zonas afectadas de protecci??n, etc. Al mismo tiempo, la medida supone una parte importante de la propia documentaci??n de los restos arqueol??gicos, que aporta informaci??n cuantitativa de la forma, dimensiones y disposici??n espacial del conjunto del yacimiento y de cada uno de sus elementos constitutivos. La investigaci??n se ve enriquecida por el enlace de las bases de datos gr??ficos y alfanum??ricos. La posterior difusi??n de resultados, tanto a nivel t??cnico como popular, se ven beneficiados por un soporte geom??trico consistente y sobre todo planificado.

Suelos de habitación - suelos de corrales: los casos de Atxoste y Los Husos

[ES] La secuencia estratigráfica de un yacimiento arqueológico responde a dos variables relacionables, aportaciones naturales y actividades antrópicas: la conjunción de analíticas propias de la arqueología y la geología permite descifrar los caracteres de dicha sedimentación y reconocer su origen. Se han aplicado exámenes sedimentológicos y químicos a los yacimientos de Atxoste y Los Husos: por sus tipologías son representativos de la dinámica cultural habida a lo largo del Holoceno y sirven en la comprensión de la formación de yacimientos arqueológicos. Ligeros elementos constructivos y la distribución de los items arqueológicos han permitido, además, delomitar una cabaña adosada al abrigo en Atxoste y los cierres de un corral en el covacho de Los Husos.

A short in-frame deletion in NTRK1 tyrosine kinase domain caused by a novel splice site mutation in a patient with congenital insensitivity to pain with anhidrosis

Background: Congenital insensitivity to pain with anhidrosis (CIPA) is a rare autosomal recessive genetic disease characterized by the lack of reaction to noxious stimuli and anhidrosis. It is caused by mutations in the NTRK1 gene, which encodes the high affinity tyrosine kinase receptor I for Neurotrophic Growth Factor (NGF). -- Case Presentation: We present the case of a female patient diagnosed with CIPA at the age of 8 months. The patient is currently 6 years old and her psychomotor development conforms to her age (RMN, SPECT and psychological study are in the range of normality). PCR amplification of DNA, followed by direct sequencing, was used to investigate the presence of NTRK1 gene mutations. Reverse transcriptase (RT)-PCR amplification of RNA, followed by cloning and sequencing of isolated RT-PCR products was used to characterize the effect of the mutations on NTRK1 mRNA splicing. The clinical diagnosis of CIPA was confirmed by the detection of two splice-site mutations in NTRK1, revealing that the patient was a compound heterozygote at this gene. One of these alterations, c.574+1G > A, is located at the splice donor site of intron 5. We also found a second mutation, c.2206-2 A > G, not previously reported in the literature, which is located at the splice acceptor site of intron 16. Each parent was confirmed to be a carrier for one of the mutations by DNA sequencing analysis. It has been proposed that the c.574+1G > A mutation would cause exon 5 skipping during NTRK1 mRNA splicing. We could confirm this prediction and, more importantly, we provide evidence that the novel c.2206-2A > G mutation also disrupts normal NTRK1 splicing, leading to the use of an alternative splice acceptor site within exon 17. As a consequence, this mutation would result in the production of a mutant NTRK1 protein with a seven aminoacid in-frame deletion in its tyrosine kinase domain. --Conclusions: We present the first description of a CIPA-associated NTRK1 mutation causing a short interstitial deletion in the tyrosine kinase domain of the receptor. The possible phenotypical implications of this mutation are discussed.

Valuing a Natura 2000 network site to inform land use options using a discrete choice experiment: An illustration from the Basque Country

One of the main problems that public institutions face in the management of protected areas, such as the European Natura 2000 network, is determining how to design and implement sustainable management plans that account for the wide range of marketed and non-marketed benefits they provide to society. This paper presents an application of a stated preference valuation approach aimed at evaluating the social preferences of the population of the Basque Country, Spain, for the key attributes of a regional Natura 2000 network site. According to our results, individuals’ willingness-to-pay (WTP) is higher for attributes associated with non-use values (native tree species and biodiversity conservation) than for attributes associated with use values (agricultural development and commercial forestry). The paper concludes that management policies related to Natura 2000 network sites should account for both for the importance of non-use values and the heterogeneity of the population's preferences in order to minimize potential land use conflicts.

Nuevos materiales arqueológicos de la cueva de «El Arco B» (Ramales de la Victoria, Cantabria)

[ES] Se presentan un colgante lítico decorado y una placa caliza con pintura localizados en la cueva de El Arco B. Ambas piezas fueron recuperadas en superficie, sin un contexto estratigráfico preciso. La evaluación de la materia prima, de la morfología del soporte y de la decoración del colgante apuntan a considerar, como probable, su pertenencia al Paleolítico superior inicial. La placa decorada no encuentra paralelos claros en el frente cantábrico, por lo cual no es posible precisar más allá de una genérica adscripción al Paleolítico superior. Los materiales arqueológicos y las pinturas rojas ya conocidos, y las nuevas evidencias aquí presentadas, apuntan a considerar el yacimiento de El Arco B como un importante centro de hábitat y de creación artística.

Las industrias prehistóricas del yacimiento de San Juan (Castro Urdiales, Cantabria) y su contextualización cronológica y cultural

[ES] El análisis directo de los ajuares lítico y óseo que se conservan del yacimiento de San juan, nos induce a plantear una hipótesis principal, según la cual la ocupación prehistórica del depósito debió producirse fundamentalmente durante el Aziliense, aunque no puede descartarse un origen anterior, en las últimas fases del Magdaleniense.

Structure-function analysis of USP1: insights into the role of Ser313 phosphorylation site and the effect of cancer-associated mutations on autocleavage

Background: In complex with its cofactor UAF1, the USP1 deubiquitinase plays an important role in cellular processes related to cancer, including the response to DNA damage. The USP1/UAF1 complex is emerging as a novel target in cancer therapy, but several aspects of its function and regulation remain to be further clarified. These include the role of the serine 313 phosphorylation site, the relative contribution of different USP1 sequence motifs to UAF1 binding, and the potential effect of cancer-associated mutations on USP1 regulation by autocleavage. Methods: We have generated a large set of USP1 structural variants, including a catalytically inactive form (C90S), non-phosphorylatable (S313A) and phosphomimetic (S313D) mutants, deletion mutants lacking potential UAF1 binding sites, a mutant (GG/AA) unable to undergo autocleavage at the well-characterized G670/G671 diglycine motif, and four USP1 mutants identified in tumor samples that cluster around this cleavage site (G667A, L669P, K673T and A676T). Using cell-based assays, we have determined the ability of these mutants to bind UAF1, to reverse DNA damage-induced monoubiquitination of PCNA, and to undergo autocleavage. Results: A non-phosphorylatable S313A mutant of USP1 retained the ability to bind UAF1 and to reverse PCNA ubiquitination in cell-based assays. Regardless of the presence of a phosphomimetic S313D mutation, deletion of USP1 fragment 420-520 disrupted UAF1 binding, as determined using a nuclear relocation assay. The UAF1 binding site in a second UAF1-interacting DUB, USP46, was mapped to a region homologous to USP1(420-520). Regarding USP1 autocleavage, co-expression of the C90S and GG/AA mutants did not result in cleavage, while the cancer-associated mutation L669P was found to reduce cleavage efficiency. Conclusions: USP1 phosphorylation at S313 is not critical for PCNA deubiquitination, neither for binding to UAF1 in a cellular environment. In this context, USP1 amino acid motif 420-520 is necessary and sufficient for UAF1 binding. This motif, and a homologous amino acid segment that mediates USP46 binding to UAF1, map to the Fingers sub-domain of these DUBs. On the other hand, our results support the view that USP1 autocleavage may occur in cis, and can be altered by a cancer-associated mutation.
