The lateral accessory lobes (LALs), paired structures that are homologous among all insect species, have been well studied for their role in pheromone tracking in silkmoths and phonotaxis in crickets, where their outputs have been shown to correlate with observed motor activity. Further studies have shown more generally that the LALs are crucial both for an insect's ability to steer correctly and
Sex pheromones facilitate species-specific sex communication within the Lepidoptera. They are detected by specialised pheromone receptors (PRs), most of which to date fall into a single monophyletic receptor lineage (frequently referred to as "the PR clade") within the odorant receptor (OR) family. Here we investigated PRs of the invasive horticultural pest, Epiphyas postvittana, commonly known as
Background: eHealth solutions have often been considered favourable for improved effectiveness and quality in healthcare services for wound management. Staff engagement related to organisational changes is a key factor for successful development and implementation of a new eHealth solution, like a digital decision support systems (DDSS). It is essential to understand the engagement process in term
Primary HPV screening for cervical cancer by HPV mRNA testing (Aptima)was implemented in January 2017, for women ≥30 through 70 years, in the Region of Skåne, Sweden. HPV positive samples underwent cytology assessment, and women with any degree of abnormal cytology were referred for colposcopy. The aim was to audit the primary HPV screening program, by comparing the cytology results to those of co
The aim of this follow-up study has been to assess retinopathy and change of treatment to insulin therapy as risk factors for mortality in diabetic patients participating in a control and screening programme for retinopathy. A total of 3220 diabetic patients, 483 with an age at diagnosis <30 years, and 2737 with an age at diagnosis ≤30 years, were included. Retinopathy was graded on fundus photogr
Control of crop pests by shifting host plant availability and natural enemy activity at landscape scales has great potential to enhance the sustainability of agriculture. However, mainstreaming natural pest control requires improved understanding of how its benefits can be realized across a variety of agroecologies. Empirical studies suggest significant but highly variable responses of natural pes
The Furongian Słowińska Formation in Poland yielded minute three-dimensionally preserved, phosphatic fossils. Based on shape and structure, two distinct types are identified. The first type comprises sinuously folded, coiled, or spiral string-shaped specimens, interpreted as faecal material, coprolites. The specimens measure between less than one and two mm, the strings being long and against thei
OBJECTIVE: The objective was to examine the outcomes of cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) during pregnancy and compare these outcomes with those in nonpregnant women of fertile age. SUMMARY BACKGROUND DATA: Although both laparoscopic cholecystectomy and ERCP are considered safe and feasible in pregnant patients, there is still concern and uncertainty regardi
Molecular blood biomarkers are lacking for high-grade (HG) gastroenteropancreatic (GEP) neuroendocrine neoplasms (NEN). To histologically distinguish between neuroendocrine carcinoma (NEC), neuroendocrine tumors G3 (NET G3), adenocarcinoma and MINEN is often challenging. The mRNA-based NETest has diagnostic, prognostic and predictive value in neuroendocrine tumors G1-2 but has not been studied in
Background: Up-to-date estimates of stroke burden and attributable risks and their trends at global, regional, and national levels are essential for evidence-based health care, prevention, and resource allocation planning. We aimed to provide such estimates for the period 1990–2021. Methods: We estimated incidence, prevalence, death, and disability-adjusted life-year (DALY) counts and age-standard
Accelerated deterioration of the constituting materials is important for the long-term performance of bridges or any other load-bearing structure with several-decades-long service life. In addition to the economic consequences due to increased maintenance and repair needs, severe deterioration can lead to catastrophic collapses with possible injuries, life losses, and impairments to infrastructure
Bacteria have a remarkable ability to adapt to different environments. When bacteria encounter stress that causes macromolecular damage in the cell, leading to a suboptimal performance of cell metabolism, they can elicit an adaptive response. In this thesis Bacillus subtilis is used as the primary model organism to study bacterial adaptation to oxygen limitation, reactive nitrogen species and disu
OBJECTIVE: To investigate the association between long term residential exposure to road traffic and railway noise and risk of incident dementia.DESIGN: Nationwide prospective register based cohort study.SETTING: Denmark.PARTICIPANTS: 1 938 994 adults aged ≥60 years living in Denmark between 1 January 2004 and 31 December 2017.MAIN OUTCOME MEASURES: Incident cases of all cause dementia and dementi
BACKGROUND: Hypertension is a significant risk factor for several neurological disorders, including stroke and dementia, yet the molecular mechanisms underlying these risks remain poorly understood. In this study, we investigated temporal proteomic remodeling of the cerebrovasculature in male spontaneously hypertensive rats and normotensive Wistar-Kyoto controls at 30 and 40 weeks of age, represen
Gonyostomum semen (Raphidophyceae) is today one of the most common flagellates in humic lakes ill Sweden and appears regularly in 30% of these lakes. The first mass development of this alga was recorded in 1948 in Lake Helgasjon, South Sweden. In this paper the life cycle of Gonyostomum is described for the first time. During the winter Gonyostomum survived as resting cysts on the surface of the b
We report here the identification of a gene associated with the hyperparathyroidism-jaw tumor (HPT-JT) syndrome. A single locus associated with HPT-JT (HRPT2) was previously mapped to chromosomal region 1q25-q32. We refined this region to a critical interval of 12 cM by genotyping in 26 affected kindreds. Using a positional candidate approach, we identified thirteen different heterozygous, germlin
An efficient method for increasing the dilution rate of brine water discharged into the sea is an inclined negatively buoyant jet from a single port or a multi-diffuser system. Such jets typically arise when brine is discharged from desalination plants. Two small-scale experimental studies were conducted to investigate the behaviour of a dense jet discharged into lighter ambient water. The first e
Popular Abstract in Swedish I denna studie har de grundläggande aspekterna på mass- och värmetransport i membrantekniken pervaporation studerats. Speciell tonvikt har lagts vid pervaporations användbarhet i samband med aromämnesåtervinning. Masstransporten i pervaporation påverkas av ett yttre masstransport- motstånd kallat koncentrationpolarisation. Detta fenomen kan orsaka att fluxen av de seleIn this study, the fundamental mass and heat transfer properties of the membrane separation process called pervaporation were investigated. The suitability of pervaporation for aroma compound recovery was especially evaluated. The mass transfer in pervaporation is affected by an external mass transfer resistance in the liquid feed boundary layer, i.e. the concentration polarization phenomenon. Th
The Garden Warbler is a classic subject for the study of Palaearctic-African bird migration strategies. Most studies have considered the situation close to the breeding areas, while the African and especially the sub-Saharan part of the species' migration have received comparatively little attention. Here we use autumn and spring ringing data from Nigeria and The Gambia to study the movements and
This paper contains a joint ESHG/ASHG position document with recommendations regarding responsible innovation in prenatal screening with non-invasive prenatal testing (NIPT). By virtue of its greater accuracy and safety with respect to prenatal screening for common autosomal aneuploidies, NIPT has the potential of helping the practice better achieve its aim of facilitating autonomous reproductive
