Apatite Fission‐Track Thermochronology in the Tamusu Area, Bayingobi Basin, NW China, and its Geological Significance
Authors: TONG Qinlong , QIN Mingkuan , YE Fawang 
Published: June 2024

AbstractThe Bayingobi basin is located in the middle of Central Asia Orogenic Belt, at the intersection of Paleo‐Asian Ocean and Tethys Ocean, as well as the junction of multiple tectonic plates. This unique tectonic setting underpins the basin's intricate history of tectonic activity. To unravel the multifaceted tectono‐thermal evolution within the southwestern region of the basin and to elucidate the implications of sandstone‐hosted uranium mineralization, granitic and clastic rock samples were collected from the Zongnai Mts. uplift and Yingejing depression, and apatite fission track (AFT) dating and thermal history simulation analysis were performed. AFT dating findings reveal that the apparent ages of all samples fall within the range of 244 Ma to 112 Ma. In particular, the bedrock of the Zongnai Mts. and Jurassic detrital apatite fission tracks have undergone complete annealing, capturing the uplift‐cooling age. Meanwhile, the AFT ages of Cretaceous detrital rocks are either equivalent to or notably exceed the age of sedimentary strata, signifying the cooling age of the provenance. A comprehensive examination of AFT ages and palaeocurrent direction analyses suggests that the Cretaceous source in the Tamusu area predominantly originated from the central and southern sectors of the Zongnai Mts. uplift. However, at a certain juncture during the Late Early Cretaceous, the Cretaceous provenance expanded to include the northern part of the Zongnai Mts. uplift. Based on the results of thermal history simulations and previous studies, it is considered that the Tamusu area has undergone four distinct tectonic uplift events since the Late Paleozoic. The first is the Late Permian to Early Triassic (260–240 Ma), which is associated with the closure of the Paleo‐Asian Ocean and the accretionary orogeny within the Alxa region. The second uplift event took place in the Early Jurassic (190–175 Ma) and corresponded to intraplate orogeny following the closure of the Paleo‐Asian Ocean. The third uplift event is the Late Jurassic to Early Cretaceous (160–120 Ma), which is linked to the East Asia's position as the convergence center of multiple tectonic plates during this period. The fourth uplift event is linked to the Late Early Cretaceous (112–100 Ma), driven either by the westward subduction of the eastern Pacific plate or the mantle upwelling resulting from the Bangong–Nujiang oceanic lithosphere subduction and slab break‐off. The primary stress orientation for the first three tectonic uplift phases approximated a nearly SN direction, while the fourth stage featured a principal stress direction of NW. The fourth tectonic uplift event of the Late Early Cretaceous and basaltic eruption thermal event during this period likely exerted a significant influence on the formation of the Tamusu sandstone‐hosted uranium deposit.
Fast, accurate and accessible calculations of leaf temperature and its physiological consequences with NicheMapR
Authors: Kearney Michael R. , Leigh Andrea 
Published: June 2024

Abstract

Mechanistic predictions of ecological niches are fundamentally based on energy and mass exchange processes that, to be realistic, must be linked to microclimate and incorporate behaviour and physiology. Estimates of leaf temperature and associated transpiration and net photosynthesis rates are fundamental in ecology, agriculture and global change biology. Equations for calculating leaf energy budgets have been available for over 60 years and complex models of stomatal behaviour have been developed. However, user‐friendly ways of estimating leaf temperature under realistic microclimatic regimes, including soil moisture effects, remain limited.

Here we show that the integrated microclimate and ectotherm functions of the NicheMapR package for the R programming environment can be used to make fast and effective estimates of leaf temperature and associated rates of water loss and photosynthesis for a wide range of leaf functional types, root depths and microhabitats. Stomatal conductance may be constant or simulated to change dynamically (a) as a function of vapour pressure deficit and CO2 concentration, (b) as a function of soil water potential and (c) as a thermoregulatory mechanism to avoid heat stress.

We tested the approach against hourly leaf temperature observations in summer from an arid shrubland in Australia, a temperate woodland in Montana USA, along an elevational gradient in Colorado USA, and at a botanical garden in Florida, USA.

National or global gridded data sets can provide the required forcing data but local observational data or some combination of local and gridded data can be used. The global ERA5 and NCEP datasets allow historical leaf energy budget calculations to be made anywhere in the world and a Shiny app has been developed to facilitate use of the model with these datasets.

Situated leaf energy budget calculations can be used to design informative field programs to collect much needed detailed temporal data on leaf temperature under natural settings, enabling better predictions and interpretations of how plants respond to environmental change.

Published: June 2024

AbstractBackgroundAccess to the neuraxial space, including lumbar punctures and neuraxial anaesthesia, is an everyday procedure in clinical practice. Traditionally these procedures rely on manual palpation technique, but ultrasound is a useful tool when patients prove challenging. Presently, there is a lack of evidence‐based guidelines for technical skills acquisition, both with and without ultrasound, and likewise, competency assessment approaches vary globally. Accordingly, we aim to assess the current evidence regarding learning and assessment in neuraxial access ultrasound, for future educational recommendations.MethodsThis scoping review will be conducted in accordance with the Preferred Reporting Items for Systematic and Meta‐Analysis (PRISMA) statement, together with the PRISMA Extension for Scoping Reviews. A systematic search strategy will be based on a PICO approach, focusing on physicians, medical students, or nurses being exposed to education, training, or assessment in procedural neuraxial access ultrasound. No comparators are obligated, but outcomes should be assessable using the Kirkpatrick four levels of training evaluation. The search will be performed in Cochrane Library, Embase, Medline, Scopus, PubMed, and CINAHL. Independently, two authors will screen the studies and conflicts will be resolved by a third author. Relevant predefined data will be extracted and analysed using a descriptive approach. The quality of the studies will be assessed using the Medical Education Research Study Quality Instrument.DiscussionThis scoping review will contribute by presenting gathered evidence of an overview of the different approaches to achieving education and training of technical skills in neuraxial access, and how skills are tested, which could guide research and future recommendations for skills development and assessment.

Published: June 2024

AbstractBackgroundNasotracheal intubation is associated with a risk of epistaxis. Several drugs, including cocaine and xylometazoline may be used as decongestants prior to nasotracheal intubation to prevent this. We hypothesized that xylometazoline would prevent epistaxis more effectively than cocaine, demonstrated by a lower proportion of patients with bleeding after nasotracheal intubation.MethodsWe conducted a single‐center, outcome assessor and analyst‐blinded, clinical randomized controlled trial following approval from the local research ethics committee and the national medicine agency. Written informed consent was obtained from all patients. Patients scheduled for surgery under general anesthesia with nasotracheal intubation were randomized to receive either 2 mL 4% cocaine or 2 mL 0.05% xylometazoline prior to nasotracheal intubation. Immediately following intubation, epistaxis was evaluated by the blinded intubating anesthetist on a four‐point scale. We measured heart rate and blood pressure the first 5 min after drug administration. Adverse events were followed up after 24 h.ResultsA total of 53 patients received cocaine and 49 patients received xylometazoline. Bleeding occurred in 32 patients receiving cocaine (60.4%) and in 34 patients receiving xylometazoline (69.4%) (p = .41, Fisher's exact test) with a difference of 9.0% (95% CI: −9.4% to 27%). There was no statistically significant difference between groups regarding the heart rate or blood pressure. No adverse cardiac events were recorded in either group.ConclusionWe found no statistically significant difference between cocaine and xylometazoline in preventing epistaxis after nasotracheal intubation, and the choice of vasoconstrictor should be based on other considerations, such as pricing, availability and medicolegal issues.

AbstractThe rationale for the use of metformin as a treatment to slow aging was largely based on data collected from metabolically unhealthy individuals. For healthspan extension metformin will also be used in periods of good health. To understand the potential context specificity of metformin treatment on skeletal muscle, we used a rat model (high‐capacity runner/low‐capacity runner [HCR/LCR]) with a divide in intrinsic aerobic capacity. Outcomes of metformin treatment differed based on baseline intrinsic mitochondrial function, oxidative capacity of the muscle (gastroc vs soleus), and the mitochondrial population (intermyofibrillar vs. subsarcolemmal). Metformin caused lower ADP‐stimulated respiration in LCRs, with less of a change in HCRs. However, a washout of metformin resulted in an unexpected doubling of respiratory capacity in HCRs. These improvements in respiratory capacity were accompanied by mitochondrial remodeling that included increases in protein synthesis and changes in morphology. Our findings raise questions about whether the positive findings of metformin treatment are broadly applicable.

Published: June 2024

AbstractBackground and aimsPreviously identified national drinking patterns in Europe lack comparability and might be no longer be valid due to changes in economic conditions and policy frameworks. We aimed to identify the most recent alcohol drinking patterns in Europe based on comparable alcohol exposure indicators using a data‐driven approach, as well as identifying temporal changes and establishing empirical links between these patterns and indicators of alcohol‐related harm.DesignData from the World Health Organization's monitoring system on alcohol exposure indicators were used. Repeated cross‐sectional hierarchical cluster analyses were applied. Differences in alcohol‐attributable harm between clusters of countries were analyzed via linear regression.SettingEuropean Union countries, plus Iceland, Norway and Ukraine, for 2000, 2010, 2015 and 2019.Participants/CasesObservations consisted of annual country data, at four different time points for alcohol exposure. Harm indicators were only included for 2019.MeasurementsAlcohol exposure indicators included alcohol per capita consumption (APC), beverage‐specific consumption and prevalence of drinking status indicators (lifetime abstainers, current drinkers, former drinkers and heavy episodic drinking). Alcohol‐attributable harm was measured using age‐standardized alcohol‐attributable Disability‐Adjusted Life Years (DALYs) lost and deaths per 100 000 people.FindingsThe same six clusters were identified in 2019, 2015 and 2010, mainly characterized by type of alcoholic beverage and prevalence drinking status indicators, with geographical interpretation. Two‐thirds of the countries remained in the same cluster over time, with one additional cluster identified in 2000, characterized by low APC. The most recent drinking patterns were shown to be significantly associated with alcohol‐attributable deaths and DALY rates. Compared with wine‐drinking countries, the mortality rate per 100 000 people was significantly higher in Eastern Europe with high spirits and ‘other’ beverage consumption [
= 90, 95% confidence interval (CI) = 55–126], and in Eastern Europe with high lifetime abstainers and high spirits consumption (
= 42, 95% CI = 4–78).ConclusionsEuropean drinking patterns appear to be clustered by level of beverage‐specific consumption, with heavy episodic drinkers, current drinkers and lifetime abstainers being distinguishing factors between clusters. Despite the overall stability of the clusters over time, some countries shifted between drinking patterns from 2000 to 2019. Overall, patterns of drinking in the European Union seem to be stable and partly determined by geographical proximity.
Unburnt areas in subtropical woodlands contain distinct reptile communities after extensive wildfire

Published: June 2024

AbstractExtensive wildfires can have profound impacts on fauna communities by altering the vegetation structure and resource availability. However, unburnt areas within a fire mosaic may be important habitat for wildlife while the surrounding area recovers after fire. To understand the importance of unburnt vegetation for reptiles, we studied community assemblages at 15 burnt and 15 unburnt sites in a subtropical woodland 12 months after a 25 000 ha wildfire. We tested the relative importance of unburnt areas and structural attributes on reptile abundance, richness, and community composition across this landscape. Unburnt areas had higher species richness and diversity, but not overall abundance. Reptile community composition differed significantly between burnt and unburnt areas. Woody debris, which was retained in unburnt areas but depleted in burnt areas, was positively associated with increased reptile diversity and richness. Our results suggest that unburnt areas are vital for maintaining reptile diversity and richness within a woodland landscape after wildfire. These findings demonstrate the importance of ensuring fire management programs retain unburnt patches of vegetation in fire‐prone landscapes to sustain reptile communities.

AbstractBackgroundPeyronie's disease is characterized by the formation of fibrotic plaques in the penile tunica albuginea. Effective treatments are limited, warranting the investigation of new promising therapies, such as the application of microRNAs that regulate fibrosis‐related genes.ObjectiveWe aimed to investigate the therapeutic potential of mimicking microRNA‐29b in a fibrin‐induced rat model of Peyronie's disease.Material/methodsThe study was designed in two phases. To establish an optimal Peyronie's disease model, rats received either human fibrin and thrombin or saline solutions into the tunica albuginea on days 0 and 5. The animal model validation was done through expression and histopathological analyses, the latest by an experienced uropathologist. After validation, we performed microRNA‐29b treatment on days 14, 21, and 28 of the study. This phase had control (normal saline) and scramble (microRNA scramble) groups. The mid‐penile shaft was removed on day 30 for histological examination and molecular analyses in both study stages.ResultsThe control group displayed typical tunica albuginea histologic architecture in the animal model validation. In Peyronie's disease group, the Hematoxylin and eosin and Masson Trichrome staining methods demonstrated an interstitial inflammatory process with concomitant dense fibrotic plaques as well as disarrangement of collagen fibers. Additionally, we found out that reduced microRNA‐29b (p = 0.05) was associated with significantly increased COL1A1 and transforming growth factor β1 genes and proteins (p > 0.05) in the Peyronie's disease group. After treatment with mimic microRNA‐29b stimulation, the Hematoxylin & eosin and Masson Trichrome staining revealed a discrete and less dense fibrotic plaque. This result was associated with significantly decreasing expression of COL1A1, COL3A1, and transforming growth factor β1 genes and proteins (p < 0.05).DiscussionThe fibrin‐induced animal model showed significant histopathological and molecular changes compared to the Control group, suggesting that our model was appropriate. Previous findings have shown that increased expression of microRNA‐29b was associated with decreased pathological fibrosis. In the present study, treatment with microRNA‐29b decreased the gene and protein expression of collagens and transforming growth factor β1. This study reveals the therapeutic potential for Peyronie's disease involving molecular targets.ConclusionMicroRNA‐29b application on the rat's tunica albuginea attenuated fibrosis, arising as a novel potential strategy for Peyronie's disease management.

AbstractBackgroundThe WHO manual for basic semen analysis and ISO 23162 describe sperm morphology assessment as a standard part of semen analysis. Older studies showed a correlation between morphology results and (artificial) conception. In more recent studies this relationship was less apparent and there is more emphasis on sperm morphology as a marker for healthy spermatogenesis (and general male health). Meantime, many laboratories ceased morphology assessment, probably due to unfamiliarity with this paradigmatic shift and to technical difficulties in the assessment, like the interpretation of morphological criteria.ObjectivesThe aim of this study was to identify morphological criteria with high variability in results in the Dutch External Quality Control (EQC) program.Material and methodsOver the period 2015–2020, a total of 72 photos of sperm cells along with dichotomous propositions based on 14 criteria as defined in WHO5 (2010) were distributed in the Dutch EQC program for semen analysis. The EQC results were evaluated for variability per criterion and for trends in time.ResultsBetween 2015 and 2020, 40 to 60 laboratories assessed the photos. Criteria with low variability between participants were related to acrosomal vacuoles, excessive residual cytoplasm, and tail metrics. In contrast, head ovality, regularity of head and midpiece contours, and alignment of the major axis of the midpiece and head led to the highest variability in outcomes. In general, there was a slightly positive trend (lower variability) in time, except for the criteria with the highest variability (stable or declining trend).Discussion and conclusionThis study indicates that there are (high) variabilities in the interpretation of the morphological criteria, leading to inconsistent outcomes of morphology assessment. The results are discussed from the perspective of imperfections in definitions and examples of the criteria as given in the WHO manuals.

AbstractIntroductionThis study aimed to report the screening performance of cell‐free DNA (cfDNA) testing for chromosomal abnormalities in twins, triplets, and vanishing twin pregnancies.Material and MethodsData were obtained from pregnant women with a multiple pregnancy or a vanishing twin pregnancy at ≥10 weeks’ gestation who requested self‐financed cfDNA testing between May 2015 and December 2021. Those that had positive screening results had diagnostic confirmatory procedures after counseling and consent. The performance of screening of the cfDNA test was determined by calculating confirmation rate and combined false‐positive rate (cFPR).ResultsData from 292 women were included after exclusion of those lost to follow‐up, with no‐result on cfDNA testing, or had reductions. Of the 292 pregnancies, 10 (3.4%) were triplets, including no cases of trisomy 21 and trisomy 18; 249 (85.3%) were twins, including 3 cases of trisomy 21 and no cases of trisomy 18 and 13; and 33 (11.3%) were vanishing twins, including 3 cases of trisomy 21 and 1 case of trisomy 18. The median (IQR) maternal age was 34 years (31–37). For triplet pregnancies, the initial no‐result rate was 10.3% (95% confidence interval [CI] 3.6–26.4), all with results after redraw. For twin pregnancies, the initial no‐result rate was 12.9% (95% CI 9.6–17.0), and the no‐result rate after redraw was 1.6% (95% CI 0.7–3.6). For vanishing twins, there were no cases with no‐result. All triplets had low‐risk cfDNA results. The confirmation rate for trisomy 21 was 100% with a FPR at 0% due to the small number of positive cases for twins. For vanishing twins, one high‐risk case for trisomy 21 and the only high‐risk case for trisomy 18 were confirmed with a cFPR of 8.3% (n = 2/24; 95% CI 2.3–25.9).ConclusionscfDNA testing in twin pregnancies has sufficient screening performance for trisomy 21 but the number of affected cases for other conditions is limited to draw any meaningful conclusion. The use of cfDNA testing in triplet pregnancies and vanishing twins remains an area for further research.
