A Systems View of the Heparan Sulfate Interactome

Heparan sulfate proteoglycans consist of a small family of proteins decorated with one or more covalently attached heparan sulfate glycosaminoglycan chains. These chains have intricate structural patterns based on the position of sulfate groups and uronic acid epimers, which dictate their ability to engage a large repertoire of heparan sulfate-binding proteins, including extracellular matrix prote

In vivo Cross-Linking MS of the Complement System MAC Assembled on Live Gram-Positive Bacteria

Protein-protein interactions are central in many biological processes, but they are challenging to characterize, especially in complex samples. Protein cross-linking combined with mass spectrometry (MS) and computational modeling is gaining increased recognition as a viable tool in protein interaction studies. Here, we provide insights into the structure of the multicomponent human complement syst

Structural determination of Streptococcus pyogenes M1 protein interactions with human immunoglobulin G using integrative structural biology

Streptococcus pyogenes (Group A streptococcus; GAS) is an important human pathogen responsible for mild to severe, life-threatening infections. GAS expresses a wide range of virulence factors, including the M family proteins. The M proteins allow the bacteria to evade parts of the human immune defenses by triggering the formation of a dense coat of plasma proteins surrounding the bacteria, includi

CYP3A7*1C allele : linking premenopausal oestrone and progesterone levels with risk of hormone receptor-positive breast cancers

BACKGROUND: Epidemiological studies provide strong evidence for a role of endogenous sex hormones in the aetiology of breast cancer. The aim of this analysis was to identify genetic variants that are associated with urinary sex-hormone levels and breast cancer risk.METHODS: We carried out a genome-wide association study of urinary oestrone-3-glucuronide and pregnanediol-3-glucuronide levels in 560

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

Breast cancer risk factors and survival by tumor subtype : pooled analyses from the Breast Cancer Association Consortium

BACKGROUND: It is not known if modifiable lifestyle factors that predict survival after invasive breast cancer differ by subtype.METHODS: We analyzed data for 121,435 women diagnosed with breast cancer from 67 studies in the Breast Cancer Association Consortium with 16,890 deaths (8,554 breast cancer-specific) over 10 years. Cox regression was used to estimate associations between risk factors and

The seaweed experience: exploring the potential and value of a marine resource

The article addresses the broader relationships between seaweed and algae as a marine resource, destination development, and sustainability. In many European countries, an industry around seaweed has emerged, ranging from high-end restaurants that provide their customers with local, seasonal and sustainableingredients, to entrepreneurs offering “harvest your own seaweed”-tours. In this explorative

Nasal symptoms increase the risk of snoring and snoring increases the risk of nasal symptoms. A longitudinal population study

Purpose: Humans have a preference for nasal breathing during sleep. This 10-year prospective study aimed to determine if nasal symptoms can predict snoring and also if snoring can predict development of nasal symptoms. The hypothesis proposed is that nasal symptoms affect the risk of snoring 10 years later, whereas snoring does not increase the risk of developing nasal symptoms. Methods: In the co

Higher stand densities can promote soil carbon storage after conversion of temperate mixed natural forests to larch plantations

Soil carbon (C) reservoirs held in forests play a significant role in the global C cycle. However, harvesting natural forests tend to lead to soil C loss, which can be countered by the establishment of plantations after clear cutting. Therefore, there is a need to determine how forest management can affect soil C sequestration. The management of stand density could provide an effective tool to con

Assessing the use of a portable time-geographic diary for detecting patterns of daily occupations

Background: A time-geographic diary approach is of interest in occupational therapy due to the inclusion of the diarist’s subjective experiences. There are several methods for detecting doing in time, but details needed for analysis are still lacking. The smartphone application POrtable Diary Data collector (PODD), a 24-hr diary based on the time-geographic diary has recently been introduced. Aim:

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

From antagonists to allies? Exploring the critical performativity of alternative organization

In this introduction to the special issue on critical performativity and alternative organization we provide a brief historico-theoretical sketch of the key concepts involved and point to ongoing pertinent debates in the field of critical management studies. We also present the articles included in the issue, which all explore aspects of how critical performativity and alternative organization may

Demonstration of two group‐specific TSTAs in adenovirus‐induced tumors

Infection of mice and rats with any one of five tested human adenovirus types belonging to groups A and B (types 3, 7, 12, 18 and 31) induced an immunity to the TSTAs of type 12 tumors as detected by the colony inhibition (CI) test. No immunity was found against an adenovirus type 1 tumor. Two adenovirus types belonging to group C (types 1 and 5) were similarly tested and found to induce a clear‐c

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
