Dublin City University, Collins Ave Ext, Whitehall, Dublin 9, Ireland. Electronic address:

Decision-making dynamics in Italian paediatric care for Intersex and Variations of Sex Characteristics (VSC) involve a complex interplay between medical practices, parental perspectives, and socio-cultural factors. This article explores how medical professionals and parents make decisions amid cultural debates on gender, the body, and autonomy. It addresses aspects of why surgical intervention, with limited child involvement, is often seen as the 'only option' in the 'conservative' culture of Italy.

Gold nanorods with small dimensions demonstrate better cellular uptake and absorption efficiency. The ability to synthesize gold nanorods while maintaining a tunable high aspect ratio is challenging as it requires careful control of reaction conditions, often employing additional steps such as pH modification or the use of polymeric additives. We demonstrate a seedless approach for the synthesis of mini (width < 10 nm) gold nanorods with tunable longitudinal surface plasmon resonance from ∼700 nm to >1000 nm and aspect ratios ranging from ∼3 to ∼7 without the use of any polymeric additives or pH modification.

The head-to-head oriented pair of melon resistance genes, and , control resistance to races 0 and 2 and papaya ringspot virus (PRSV), respectively. They encode, via several RNA splice variants, TIR-NBS-LRR proteins, and Prv has a C-terminal extra domain with a second NBS homologous sequence. In other systems, paired R-proteins were shown to operate by "labor division," with one protein having an extra integrated domain that directly binds the pathogen's Avr factor, and the second protein executing the defense response.

Empirical evidence suggests fishes meet the criteria for experiencing pain beyond a reasonable doubt and zebrafish are being increasingly used in studies of pain and nociception. Zebrafish are adopted across a wide range of experimental fields and their use is growing particularly in biomedical studies. Many laboratory procedures in zebrafish involve tissue damage and this may give rise to pain.

Delocalization of occupied orbitals impacts the chemical bonding in the simplest known pernitroanions [(NO)C] (1) and [(NO)N] (2) as well as other functionalized organic anions. By quantitatively mapping it onto molecular backbones of 1, 2, [CHNO] (3), [CHNNO] (4) and [C(N)] (6) anions (all modeled by QM calculations), the Weinhold's NBO analysis refines their chemical structure, enabling to explain and even predict their essential chemical behaviour. In detail, the HOMO of 1 and 2 is associated with the central atom to the degree of 70.

The dicentric chromosome assay (DCA), is considered the 'gold standard' for radiation biodosimetry. Yet, DCA, as currently implemented, may be impractical for emergency response applications, especially when time is of the essence, owing to its labor-intensive and time-consuming nature. The growth of a primary lymphocyte culture for 48 h in vitro is required for DCA, and manual scoring of dicentric chromosomes (DCs) requires an additional 24-48 h, resulting in an overall processing time of 72-96 h for dose estimation.

Article Synopsis
  • During the COVID-19 pandemic, different regions experienced panic buying for specific essentials, such as butter in France and pasta in Italy.
  • The phenomenon of panic buying leads to increased demand and price hikes, where retailers set prices for scarce products as manufacturers attempt to regulate costs for consumers.
  • The analysis reveals that despite manufacturers' intentions to subsidize retailers or consumers to control prices, there is a necessary budget threshold for effective subsidization, suggesting that simply putting more money towards subsidies might not solve the problem of rising prices.

Ocean acidification, due to the increase of carbon dioxide (CO) concentration in the atmosphere and its absorption by the oceans, affects many aspects of marine calcifying organisms' biology, including reproduction. Most of the available studies on low pH effects on coral reproduction have been conducted on tropical species under controlled conditions, while little information is reported for either tropical or temperate species in the field. This study describes the influence of decreasing pH on sexual reproduction of the temperate non-zooxanthellate colonial scleractinian , transplanted in four sites along a natural pH gradient at the underwater volcanic crater of Panarea Island (Tyrrhenian Sea, Italy).

The lack of stable electrode materials for water-based electrolytes due to the intercalation and conversion reaction mechanisms encourage scientists to design new or renovate existing materials with better cyclability, capacity, and cost-effectiveness. Ag[Fe(CN)] is a material belonging to the Prussian blue family that can be used, as its other family members, as an electrode material with the intercalation/deintercalation reaction or conversion-type mechanism through Ag oxidation/reduction. However, due to the instability of this material in its dry state, it decomposes to AgCN and a Prussian blue residual complex.

Wastewater reclamation is becoming a top global interest as population growth and rapid industrialization pose a major challenge that requires development of sustainable cost-effective technologies and strategies for wastewater treatment. Carbon nanomembranes (CNMs)-synthetic 2D carbon sheets-can be tailored chemically with specific surface functions and/or physically with nanopores of well-defined size as a strategy for multifunctional membrane design. Here, we explore a bifunctional design for combined secondary wastewater effluent treatment with dual action of membrane separation and advanced oxidation processes (AOP), exploiting dissolved oxygen.

Understanding the structural and mechanistic details of protein-DNA interactions that lead to cellular defence against toxic metal ions in pathogenic bacteria can lead to new ways of combating their virulence. Herein, we examine the Copper Efflux Regulator (CueR) protein, a transcription factor which interacts with DNA to generate proteins that ameliorate excess free Cu(i). We exploit site directed Cu(ii) labeling to measure the conformational changes in DNA as a function of protein and Cu(i) concentration.

We sought to examine new parents' perceptions of their infant during the worldwide spread of COVID-19, exploring the contribution of gender, personal resources (attachment orientation, presence of meaning in life and intolerance of uncertainty) and COVID-19-related anxieties. A convenience sample of 606 Israeli first-time parents (137 fathers and 469 mothers), whose child was 3-12 months old, was recruited through social media during April 2020. Findings indicate that being a woman, younger age, lower education, better physical health, older infant's age, lower attachment anxiety, higher presence of meaning in life and greater COVID-19-related anxiety over the infant's health contributed significantly to a greater perception of infant's warmth; being a father, higher education and economic status, poorer physical health, higher attachment anxiety and intolerance of uncertainty and less presence of meaning in life contributed significantly to a greater perception of infant's invasiveness.

We present a 'top-down' patterning technique based on ion milling performed at low-temperature, for the realization of oxide two-dimensional electron system devices with dimensions down to 160 nm. Using electrical transport and scanning Superconducting QUantum Interference Device measurements we demonstrate that the low-temperature ion milling process does not damage the 2DES properties nor creates oxygen vacancies-related conducting paths in the STO substrate. As opposed to other procedures used to realize oxide 2DES devices, the one we propose gives lateral access to the 2DES along the in-plane directions, finally opening the way to coupling with other materials, including superconductors.
