Aims and objectives:This article investigates naturalistic acquisition of a second dialect (D2), comparing the global accent of speakers of Brazilian Portuguese (BP) exposed to European Portuguese (EP), either as children or as adults (early vs late bilectals). The focus is on the predicted advantage of an early age of onset of the D2, as well as possible crosslinguistic influence from the D2 onto
PURPOSE: We studied the relative contributions of total peripheral resistance (TPR), stroke volume (SV) and heart rate (HR) to low blood pressure in classical orthostatic hypotension (cOH) on group and individual levels.METHODS: We retrospectively analyzed tilt test records from cOH patients and age/sex-matched controls. We quantified relative effects of HR, SV and TPR on mean arterial pressure (M
Venomous animals have evolved diverse molecular mechanisms to incapacitate prey and defend against predators. Most venom components disrupt nervous, locomotor, and cardiovascular systems or cause tissue damage. The discovery that certain fish-hunting cone snails use weaponized insulins to induce hypoglycemic shock in prey highlights a unique example of toxins targeting glucose homeostasis. Here, w
Drought and rainfall events will become more frequent and intense with climate change. At the same time, soil moisture is one of the major factors controlling soil microbial processes such as carbon cycling. When challenged with drought there are two main growth responses microorganisms can use: (1) they can maintain growth rates during drought (i.e., resistance) and (2) they can recover growth ra
Poly-ADP-ribose polymerases (PARPs) catalyze transfer of ADP-ribose from NAD(+) to specific residues in their substrate proteins or to growing ADP-ribose chains. PARP activity is involved in processes such as chromatin remodeling, transcription control, and DNA repair. Inhibitors of PARP activity may be useful in cancer therapy. PARP2 is the family member that is most similar to PARP1, and the two
The development of exocrine pancreas function was studied in Swedish Landrace pigs surgically fitted with a chronic pancreatic duct catheter and a duodenal re-entrant cannula. The juice secretion and output of total protein and trypsin activity were followed before (basal secretion) and after feeding (postprandial secretion) during the first 1-13 weeks of life. The results showed that throughout t
What does it mean to do Islamic Studies within Religious Studies? Taking the cue from Thomas A. Tweed's intervention, this article discusses new theoretical and methodological approaches in Religious Studies and their relevance to researching Islam. Such approaches cross geographical, disciplinary, and intellectual boundaries while equally being emplaced in particular socio-cultural contexts that
Interactions between microbiomes and metabolites play crucial roles in the environment, yet how these interactions drive greenhouse gas emissions during ecosystem changes remains unclear. Here we analysed microbial and metabolite composition across a permafrost thaw gradient in Stordalen Mire, Sweden, using paired genome-resolved metagenomics and high-resolution Fourier transform ion cyclotron res
Slight modifications to the manufacturer’s protocol (Qiagen #12966-10, now discontinued and replaced with #12988-10) enabled the successful extraction of high-quality DNA and RNA from permafrost peat samples. Integrating the DNA and RNA purification steps immediately after the extraction process helped streamline the workflow, resulting in consistent quality nucleic acids suitable for downstream s
Permanent ponds represent key landscape components that support biodiversity and supply various ecosystem services. Notably, the export of aquatic subsidies to land via emerging insects, may significantly influence terrestrial food webs. Various factors, including eutrophication, can influence these exports. Polyunsaturated fatty acids (PUFA), which greatly enhance consumer fitness, are among the
Laser-based diagnostic techniques have been utilized to analyse a variety of processes, offering valuable insights on temperature and species concentrations with non-intrusive measurements, while maintaining high temporal and spatial resolution. With the advent of technology and the introduction of lasers with high peak power, such as femto-second (fs) lasers, the full potential of these diagnosti
The European Green Deal recognises the importance of addressing the environmental challenges posed by agriculture to meet the global biodiversity and climate agendas. Environmental policymaking is needed to drive and speed up sustainability transitions in agriculture because the environmental consequences of agricultural activities are not generally reflected in production costs and lead to market
Antimicrobial peptides (AMPs), particularly host defense peptides (HDPs), have gained recognition for their role in host defense mechanisms, but they have also shown potential as a promising anticancer, antiviral, antiparasitic, antifungal and immunomodulatory agent. Research studies in recent years have shown HDPs play a crucial role in endothelial cell function and biology. The function of endot
Arctic tundra ecosystems store a significant proportion of the global soil organic carbon (C). However, warming-induced shrub encroachment and reindeer (Rangifer tarandus L.) grazing regimes promoting graminoid vegetation may strongly influence tundra soil C stability. Here, we studied how reindeer grazing intensity and experimental warming affect soil C stabilization in a tundra ecosystem. We hyp
The daily transition between day and night, known as the diel cycle, is characterised by significant shifts in environmental conditions and biological activity, both of which can affect crucial ecosystem functions like pollination. Despite over six decades of research into whether pollination varies between day and night, consensus remains elusive. We compiled the evidence of diel pollination from
We have previously reported that 4-(3-(tert-butylamino)imidazo[1,2-α]pyridine-2-yl)benzoic acid, a bicyclic N-fused aminoimidazoles derivative (BNFA-D), possesses anticancer potentiality against breast and kidney cancer cells with minimal toxicities to corresponding normal cells. Here, we explored the mechanism of action of BNFA-D in breast cancer cells using multiple cell-based assays such as MTT

Pesticide exposure can be harmful to insect pollinators and the ecosystem services they provide. As many pesticide guidelines warn against applying such products when pollinators are active, it is important to evaluate how pollinator activity changes with time of day to determine the most appropriate time to spray.We walked transects from sunrise to sunset in oilseed rape (Brassica napus L.) field
