The influence of fetal sex on antenatal maternal glucose and insulin dynamics.

The 'Developmental Origins of Health and Disease' (DOHaD) hypothesis postulates that exposures during critical periods of development and growth, including maternal hyperglycemia, can have significant consequences for short- and long-term health in offspring. The influence of fetal status on maternal (patho)physiology is less well understood but gaining attention. Fetal sex specifically may be an independent risk factor for a range of adverse pregnancy outcomes, including increased gestational diabetes mellitus (GDM) frequency with male fetuses in multi-ethnic populations.

A methotrexate labelled dual metal oxide nanocomposite for long-lasting anti-cancer theranostics.

We explored the feasibility of a self-assembled chitosan nanocomposite incorporating cerium oxide/nanoceria and superparamagnetic iron oxide nanoparticles (Chit-IOCO NPs), conjugated with methotrexate (MTX) and Cy5 dye, as an integrated cancer theranostic nanosystem (Chit-IOCO-MTX-Cy5). In this system, nanoceria serves as an anti-cancer agent, while the superparamagnetic iron oxide nanoparticles function as a negative contrast agent for MR imaging. This dual metal oxide nanocomposite is conjugated with MTX which is a structural analogue of folate, serving both as a targeting mechanism for folate receptors on cancer cells and as a chemotherapeutic drug.

Experimental Investigation of the Effect of Microstructure on Coalbed Methane Adsorption Characteristics Affected by Chemical Solvents.

Coalbed methane (CBM) reservoir modification based on chemical solvent treatment could change the coal microstructure, which further affects the adsorption capacity and flow characteristics of this clean energy. Coal samples were extracted by tetrahydrofuran (THF), carbon disulfide (CS), and hydrochloric acid (HCl). Low-pressure nitrogen adsorption, carbon dioxide adsorption, Fourier transform infrared spectroscopy, and methane isothermal adsorption test were adopted.

Effect of ultrafine CO2 bubbles on Euglena gracilis Z growth with CO2 gas bubble size and chlorophyll content.

Microalgae have been explored as a viable alternative food source. Among them, Euglena gracilis stands out as a promising single-cell algae. However, the challenge lies in developing more efficient and cost-effective methods for industrial mass production of Euglena gracilis under controlled culture conditions.

Health checks for autistic adults: study protocol for a cluster randomised controlled trial.

Background: Autistic people commonly have physical and mental health conditions. They also frequently experience barriers to accessing healthcare, contributing to problems identifying and treating health conditions. These factors may lead to increased and earlier morbidity and lower average life expectancy for autistic people.

Understanding the coupled relationship between regional longevity and physical geographical environment in Hechi, Guangxi, China.

Healthy ageing plays an important role in ageing societies in many countries, and centenarians are a sign of longevity. Longevity and its determinants have become issues of global concern and also a focus of research. Although many disciplines have conducted out a series of studies on longevity phenomena, few studies have systematically considered the impact of geographical environmental factors.

Environmental exposure and cancer occurrence in dogs: a critical appraisal of evidence.

Cancer is a significant contributor to morbidity and mortality in humans and is also the leading cause of death in dogs. It is estimated that up to 20 % of human cancers can be explained by environmental exposures to carcinogens. It has been hypothesized that companion animals such as dogs could not only be a model for the complex pathogenic processes of human cancers, but also act as sentinels for environmental carcinogens due to their relative shorter longevity, spontaneous occurrence of tumours, and intimate relationship with our everyday environments.

Soil carbon fractionation as a tool to monitor coastal wetland rehabilitation.

Coastal wetland rehabilitation can provide nature-based solutions for climate change mitigation. The high carbon accumulation rate and carbon secured, potentially for several millennia, as soil organic carbon (SOC), is among the reasons. Measuring SOC storage and accrual over time are the main tools to understand rehabilitation success.

Correlations of facial soft tissue thicknesses with craniometric dimensions improve craniofacial identification estimates: Fact or fiction?

Linear regression (LR) models that use cranial dimensions to estimate facial soft tissue thicknesses (FSTTs) have been posited by Simpson and Henneberg to assist craniofacial identification. For these regression equations to work well, the independent (craniometrics) and dependent (FSTTs) variables must be tightly correlated; however, such relationships have not been routinely demonstrated for adult humans. To examine the strength of these relationships further, this study employed magnetic resonance (MR) imaging to unambiguously measure cranial dimensions and FSTTs for 38 adult cadavers.

A graphical exploration of the relationship between parasite aggregation indices.

The level of aggregation in parasite populations is frequently incorporated into ecological studies. It is measured in various ways including variance-to-mean ratio, mean crowding, the k parameter of the negative binomial distribution and indices based on the Lorenz curve such as the Gini index (Poulin's D) and the Hoover index. Assuming the frequency distributions follow a negative binomial, we use contour plots to clarify the relationships between aggregation indices, mean abundance and prevalence.

From museum drawer to tree: Historical DNA phylogenomics clarifies the systematics of rare dung beetles (Coleoptera: Scarabaeinae) from museum collections.

Although several methods exist for extracting and sequencing historical DNA originating from dry-preserved insect specimens deposited in natural history museums, no consensus exists as to what is the optimal approach. We demonstrate that a customized, low-cost archival DNA extraction protocol (∼€10 per sample), in combination with Ultraconserved Elements (UCEs), is an effective tool for insect phylogenomic studies. We successfully tested our approach by sequencing DNA from scarab dung beetles preserved in both wet and dry collections, including unique primary type and rare historical specimens from internationally important natural history museums in London, Paris and Helsinki.

Highly Efficient Photocatalytic CO2-to-CO on Ni-Based Cationic Polymer with TiO2-Assisted Exfoliation and Stabilization.

Porous organic polymers have shown great potential in photocatalytic CO2 reduction due to their unique tunable structure favoring gas adsorption and metal sites integration. However, efficient photocatalysis in porous polymers is greatly limited by the low surface reactivity and electron mobility of bulk structure. Herein, we incorporate TiO2 nanoparticles and Ni(II) sites into a layered cationic imidazolium polymer (IP), in which the imidazolium moieties and free anions can stabilize the key intermediates and enhance the reaction kinetics of CO2 reduction.

The Multi-Kinase Inhibitor GZD824 (Olverembatinib) Shows Pre-Clinical Efficacy in Endometrial Cancer.

Objective: Endometrial cancer is one of the few cancers for which mortality is still increasing. A lack of treatment options remains a major challenge, particularly for some subtypes of the disease. GZD824, also known as olverembatinib, is a multi-kinase inhibitor previously investigated in clinical trials for chronic myeloid leukaemia and Ph+ acute lymphoblastic leukaemia as a BCR-ABL inhibitor.

Disrupted callosal connectivity underlies long-lasting sensory-motor deficits in an NMDAreceptor antibody encephalitis mouse model.

NMDA receptor mediated autoimmune encephalitis (NMDAR-AE) frequently results in persistent sensory-motor deficits, especially in children, yet the underlying mechanisms remain unclear. This study investigated the long- term effects of exposure to a patient-derived GluN1-specific monoclonal antibody (mAb) during a critical developmental period (from postnatal day 3 to day 12) in mice. We observed long-lasting sensory-motor deficits characteristic of NMDAR-AE, along with permanent changes in callosal axons within the primary somatosensory cortex (S1) in adulthood, including increased terminal branch complexity.

Coefficients in Taylor's law increase with the time scale of water clarity measurements in a global suite of lakes.

Identifying the scaling rules describing ecological patterns across time and space is a central challenge in ecology. Taylor's law of fluctuation scaling, which states that the variance of a population's size or density is proportional to a positive power of the mean size or density, has been widely observed in population dynamics and characterizes variability in multiple scientific domains. However, it is unclear if this phenomenon accurately describes ecological patterns across many orders of magnitude in time, and therefore links otherwise disparate observations.

Ecosystem Knowledge Should Replace Coexistence and Stability Assumptions in Ecological Network Modelling.

Quantitative population modelling is an invaluable tool for identifying the cascading effects of conservation on an ecosystem. When population data from monitoring programs is not available, deterministic ecosystem models have often been calibrated using the theoretical assumption that ecosystems have a stable, coexisting equilibrium. However, a growing body of literature suggests these theoretical assumptions are inappropriate for conservation contexts.

Fates of nutrient elements and heavy metals during thermal conversion of cattle slurry-derived anaerobic digestates.

Thermal processes are emerging as promising solutions to recovering phosphorus and other nutrient elements from anaerobic digestates. The feasibility of nutrient element recovery depends largely on the fates of nutrient elements and heavy metals during thermal processing. This study assesses the partitioning of macronutrients (N, P, K, Na, Ca and Mg) and heavy metals (Zn, Cu, and Mn) between condensed and gaseous phases during thermal conversion of cattle slurry digestates in gas atmospheres of pyrolysis, combustion, and gasification processes.

The perspectives of remote sensing and GIS on military environmental impacts: a systematic review.

Military operations have long been recognized to cause significant environmental consequences. However, research on the environmental impacts of military operations remains fragmented despite the rise of modern technologies, including remote sensing (RS) and geographic information system (GIS). Hence, this study sought to review the literature on using RS and GIS approaches to assess military operations' environmental impacts.

Oxidative potential and persistent free radicals in dust storm particles and their associations with hospitalization.

Sand and dust storms (SDS) can cause adverse health effects, with the oxidative potential (OP) and environmentally persistent free radicals (EPFRs) inducing oxidative stress. We mapped the OP and EPFRs concentrations at 1735 sites in China during SDS periods using experimental data for 2021-2023 and a random forest model. We examined 855,869 hospitalizations during SDS events for 2015-2022 in Beijing, China.

Floristic classifications and bioregionalizations are not predictors of intra-specific evolutionary patterns.

The relationship between intra-specific and inter-specific patterns and processes over evolutionary time is key to ecological investigations. We examine this relationship taking an approach of focussing on the association between vegetation and floristic classifications, summaries of inter-specific processes, and intra-specific genetic structuring. Applying an innovative, multispecies, and standardised population genomic approach, we test the relationship between vegetation mapping schemes and structuring of genetic variation across a large, environmentally heterogenous region in eastern Australia.

Evaluation of the Short-Term Restorative Care program: Effects on physical functioning.

Objective: The Short-Term Restorative Care program is an 8-week multidisciplinary early intervention funded by the Australian Government that aims to reverse or slow the functional decline of older Australians. Despite the large investment of tax-payer money to fund the program, very little peer-reviewed literature exists examining the ability of the program to deliver on its aims.

Methods: This was a retrospective cohort study.

Non-Analog Behaviour of Eastern African Herbivore Communities During the Last Glacial Period.

Modern African ungulates navigate seasonal variation in resource availability through diet-switching (primarily mixed-feeders) and/or migrating (primarily grass grazers). These ecological generalisations are well-documented today, but the extent to which they apply to the non-analog ecosystems of the Pleistocene are unclear. Drawing from serially-sampled stable isotope measurements from 18 Kenyan large herbivore species from the Last Glacial Period (LGP), we evaluate how diet, diet-switching, and migration compare to observations from present-day settings.

Calibrated Ecosystem Models Cannot Predict the Consequences of Conservation Management Decisions.

Ecosystem models are often used to predict the consequences of management interventions in applied ecology and conservation. These models are often high-dimensional and nonlinear, yet limited data are available to calibrate or validate them. Consequently, their utility as decision-support tools is unclear.
