Lack of gene flow : Narrow and dispersed differentiation islands in a triplet of Leptidea butterfly species

Genome scans in recently separated species can inform on molecular mechanisms and evolutionary processes driving divergence. Large-scale polymorphism data from multiple species pairs are also key to investigate the repeatability of divergence-whether radiations tend to show parallel responses to similar selection pressures and/or underlying molecular forces. Here, we used whole-genome resequencing

Five Year Results of Off the Shelf Fenestrated Endografts for Elective and Emergency Repair of Juxtarenal Abdominal Aortic Aneurysm

Objective: Fenestrated endovascular aneurysm repair (FEVAR) is a well established treatment for complex abdominal aortic aneurysms (AAAs). FEVAR with custom made devices (CMDs) has limitations in both the emergency and elective settings due to time consuming manufacture. “Off the shelf” (OTS) fenestrated stent grafts are a potential solution. The primary goal was to evaluate the five year outcome

High-resolution macromolecular crystallography at the FemtoMAX beamline with time-over-threshold photon detection

Protein dynamics contribute to protein function on different time scales. Ultrafast X-ray diffraction snapshots can visualize the location and amplitude of atom displacements after perturbation. Since amplitudes of ultrafast motions are small, high-quality X-ray diffraction data is necessary for detection. Diffraction from bovine trypsin crystals using single femtosecond X-ray pulses was recorded

Den obarocka fabeln – eller den barocka? : Några turer kring en genre och ett litteraturhistoriskt begrepp

As a contribution to the discussion on the relevance of the baroque concept in Swedish literary history, the article conducts a case study by testing the concept on the history of a specific genre: the Aesopic fable. The argument takes its starting point in the analysis of German fable history by the pioneering baroque scholar Wolfgang Kayser who asserted a lack of German fable writing during the

Transcatheter Aortic Valve Replacement With the LOTUS Edge System : Early European Experience

Objectives: The aim of this study was to evaluate the short-term safety and efficacy of transcatheter aortic valve replacement (TAVR) with the LOTUS Edge system. Background: The LOTUS Edge system was commercially re-released in April 2019. The authors report the first European experience with this device. Methods: A multicenter, single-arm, retrospective registry was initiated to evaluate short-te

Oral contraceptive use and ovarian cancer risk for BRCA1/2 mutation carriers : an international cohort study

BACKGROUND: Ovarian cancer risk in BRCA1 and BRCA2 mutation carriers has been shown to decrease with longer duration of oral contraceptive preparations (OCPs) use. While the effects of OCPs in the general population are well established (∼50% reduction), the estimated risk reduction in mutation carriers is much less precise due to potential bias and small sample sizes. In addition, only a few stud

Cross-Cancer Genome-Wide Association Study of Endometrial Cancer and Epithelial Ovarian Cancer Identifies Genetic Risk Regions Associated with Risk of Both Cancers

BACKGROUND: Accumulating evidence suggests a relationship between endometrial cancer and ovarian cancer. Independent genome-wide association studies (GWAS) for endometrial cancer and ovarian cancer have identified 16 and 27 risk regions, respectively, four of which overlap between the two cancers. We aimed to identify joint endometrial and ovarian cancer risk loci by performing a meta-analysis of

Generalized Two-Magnitude Check Node Updating with Self Correction for 5G LDPC Codes Decoding

The min-sum (MS) and approximate-min* (a-min*) algorithms are alternatives of the belief propagation (BP) algorithm for decoding low-density parity-check (LDPC) codes. To lower the BP decoding complexity, both algorithms compute two magnitudes at each check node (CN) and pass them to the neighboring variable nodes (VNs).In this work we propose a new algorithm, ga-min*, that generalizes the MS and

PM 2/21 : Methods for assessing the effects of plant protection products on biodiversity

Lunds universitet fick i uppdrag av Kemikalieinspektionen att kartlägga och beskriva ansatser till metoder som bedömer indirekta effekter av växtskyddsmedel på individer och populationer och studier som utvärderar om nuvarande riskbedömningsmetoder är tillräckliga för att bedöma direkta effekter av växtskyddsmedel på biologisk mångfald. Uppdraget utfördes i två delar. För det första inventerade viLund University was commissioned by the Swedish Chemicals Agency to map and describe emerging methodologies that assess the indirect impact of plant protection products on nontarget organism individuals and populations, and studies that evaluates if current risk assessment methodologies are sufficient to assess direct effects of plant protection products on biodiversity. The commission was perform

Effect of BCG and allogeneic tumour cells on adenovirus type 12 tumorigenesis in mice

HAMSTERS and mice inoculated at birth with tumour viruses have been used in studies of the prophylactic effects of various treatments during the latent period. The incidence of primary tumours in hamsters infected at birth with SV40 is reduced if the virus is inoculated during the latent period1-3. Similar administration of adenovirus type 12 also inhibited the induction of tumours by SV404; this

Higher concordance of PD-L1 expression between biopsies and effusions in epithelioid than in nonepithelioid pleural mesothelioma

BACKGROUND: Malignant mesothelioma (MM) is a therapy-resistant tumor, often causing an effusion. Drugs targeting the programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) pathway have shown promising results, but assessment of PD-L1 expression to select patients for therapy has mainly been performed on histologic tissue samples. In a previous study, we showed that MM effusions are
