Geoelectrical imaging for site investigation for urban underground infrastructure : a TRUST-project

Unforeseen ground conditions are risk factors often leading to delays and significant additional costs in conjunction with underground infrastructure construction work. There are two main geological hazards that are important to identify, manage, or possibly avoid, for safe and efficient underground construction. The first is unstable rock and the second is large groundwater inflow. The latter exi

Multiple splicing variants of the estrogen receptor are present in individual human breast tumors

Transcript variants of the estrogen receptor (ER) were investigated in 109 primary breast tumors using reverse transcription-polymerase chain reaction (RT-PCR) and primers allowing analysis of each internal exon. A high incidence of different ER variants was observed, each individual tumor often manifesting multiple variants coexisting with corresponding wildtype (wt) ER. These variants, by sequen

An estrogen receptor mutant with strong hormone-independent activity from a metastatic breast cancer

Thirty tumors from metastatic breast cancer patients were screened for mutations in the estrogen receptor (ER) gene using single-strand conformation polymorphism and sequence analysis. Three missense mutations, Ser47Thr, Lys531Glu, and Tyr537Asn, were identified in these lesions. To investigate these mutated ERs or altered transcriptional activation function, expression vectors containing wild-typ

A hypersensitive estrogen receptor-alpha mutation in premalignant breast lesions

The best current model of breast cancer evolution suggests that most cancers arise from certain premalignant lesions. We have identified a common (34%) somatic mutation in the estrogen receptor (ER)-alpha gene in a series of 59 typical hyperplasias, a type of early premalignant breast lesion. The mutation, which affects the border of the hinge and hormone binding domains of ER-alpha, showed increa

Grundvattendagarna 2013

Den här rapporten innehåller en sammanställning av abstracts som ligger till underlag för de presentationer som presenterades på konferensen Grundvattendagarna i Lund den 16–17 oktober 2013. Konferensen anordnades av SGU i samarbete med Geologiska institutionen på Lunds uni-versitet och Länsstyrelsen Skåne. Ett av konferensens syften var att få till en bred uppslutning från olika organisationer, m

Arsenic Research and Global Sustainability: Proceedings of the Sixth International Congress on Arsenic in the Environment (As2016), June 19-23, 2016, Stockholm, Sweden

The Congress "Arsenic in the Environment" offers an international, multi- and interdisciplinary discussion platform for research and innovation aimed towards a holistic solution to the problem posed by the environmental toxin arsenic, with considerable societal impact. The congress has focused on cutting edge and breakthrough research in physical, chemical, toxicological, medical, agricultural and

Vatten, vatten, bara vanligt vatten?

Vatten är en naturresurs som vi kanske tar lite för mycket för givet i vårt land. Grundvattenforskaren charlotte Sparrenbom menar att skyddet av den kanske viktigaste naturresursen för vår överlevnad är kraftigt eftersatt. hon vill väcka till eftertanke om hur vårt fotavtryck ser ut för kommande generationer, och föreslå sätt att komma igång med bättre skydd av vårt vatten.

From ’big’ to ’much’ : On the grammaticalisation of some gradable adjectives in Swedish

In this paper, I give a short description of a language change that can be viewedas an instance of grammaticalization, namely the transition of the two adjectivesmycken/t and liten/t into quantifiers. Data from the corpus of Swedish drama dialogue reveal that liten/t became a quantifier as early as the 1700s, whereas mycken/t seems to have gone through the same change roughly 150 years later. Inhe

Detecting the True Extent of Introgression during Anthropogenic Hybridization

Hybridization among naturally separate taxa is increasing owing to human impact, and can result in taxon loss. Previous classification of anthropogenic hybridization has largely ignored the case of bimodal hybrid zones, in which hybrids commonly mate with parental species, resulting in many backcrossed individuals with a small proportion of introgressed genome. Genetic markers can be used to detec

Two Orders of Magnitude Variation in the Star Formation Efficiency across the Premerger Galaxy NGC 2276

We present the first spatially resolved (∼0.5 kpc) measurements of the molecular gas depletion time τ depl across the disk of the interacting spiral galaxy NGC 2276, a system with an asymmetric morphology in various star formation rate (SFR) tracers. To estimate τ depl, we use new NOEMA observations of the 12CO(1-0) emission tracing the bulk molecular gas reservoir in NGC 2276, and extinction-corr

Principles of niche expansion

Niche expansion is attained by adaptations in two generalized phenotypical traits - niche position and niche width. This gives room for a wide range of conceptual ways of niche filling. The niche variation hypothesis reduces the range by predicting that expansion occurs by increasing variation in niche position, which has been debated on empirical and theoretical grounds as also other options seem

Scrutinizing the cut-off for “pathological” meniscal body extrusion on knee MRI

Objectives: Medial meniscal body extrusion ≥ 3 mm on MRI is often considered “pathologic.” The aims of this study were to (1) assess the adequacy of 3 mm as cut-off for “pathological” extrusion and (2) find an optimal cut-off for meniscal extrusion cross-sectionally associated with radiographic knee osteoarthritis, bone marrow lesions (BMLs), and cartilage damage. Methods: Nine hundred fifty-eight
