AbstractC4AF is considered the least reactive main clinker phase, but its reactivity may be affected by adding supplementary cementitious materials (SCMs). Pure C4AF was synthesised in a laboratory furnace, and the role of silica fume without gypsum on its early hydration properties was monitored. Burning was carried out in four stages to achieve 99% purity of C4AF. Heat flow development was monitored by isothermal calorimetry over 7 days of hydration at 20°C and 40°C. The role of silica fume on hydrogarnet phase katoite (Ca3Al2(SiO4)3 – x(OH)4x x = 1.5–3) formation during early hydration was studied. Rapid dissolution of C4AF, formation of metastable C‐(A,F)‐H and its conversion to C3(A, F)H6 was evidenced by isothermal calorimetry as a large exotherm. Changes in microstructure during early hydration were documented by SE micrographs, EDS point analyses, X‐ray mapping and line scans by SEM‐EDS. The phase composition was characterised by DTA‐TGA and QXRD after 7 days of hydration. The katoite diffraction pattern is similar for the reference sample and sample with silica fume, but substitution in its structure can be revealed by X‐ray microanalyses. The composition of katoite is variable due to the various extent of substitution of 4OH− by SiO44− due to silica fume.

AbstractNowadays, the use of super‐resolution microscopy (SRM) is increasing globally due to its potential application in several fields of life sciences. However, a detailed and comprehensive guide is necessary for understanding a single‐frame image's resolution limit. This study was performed to provide information about the structural organisation of isolated cellulose fibres from garlic and agave wastes through fluorophore‐based techniques and image analysis algorithms. Confocal microscopy provided overall information on the cellulose fibres’ microstructure, while techniques such as total internal reflection fluorescence microscopy facilitated the study of the plant fibres’ surface structures at a sub‐micrometric scale. Furthermore, SIM and single‐molecule localisation microscopy (SMLM) using the PALM reconstruction wizard can resolve the network of cellulose fibres at the nanometric level. In contrast, the mean shift super‐resolution (MSSR) algorithm successfully determined nanometric structures from confocal microscopy images. Atomic force microscopy was used as a microscopy technique for measuring the size of the fibres. Similar fibre sizes to those evaluated with SIM and SMLM were found using the MSSR algorithm and AFM. However, the MSSR algorithm must be cautiously applied because the selection of thresholding parameters still depends on human visual perception. Therefore, this contribution provides a comparative study of SRM techniques and MSSR algorithm using cellulose fibres as reference material to evaluate the performance of a mathematical algorithm for image processing of bioimages at a nanometric scale. In addition, this work could act as a simple guide for improving the lateral resolution of single‐frame fluorescence bioimages when SRM facilities are unavailable.

AbstractOligodendrocytes are the myelinating cells in the CNS and multiple sclerosis (MS) is a demyelinating disorder that is characterized by progressive loss of myelin. Although oligodendroglial progenitor cells (OPCs) should be differentiated into oligodendrocytes, for multiple reasons, OPCs fail to differentiate into oligodendrocytes in MS. Therefore, increasing the maturation of OPCs to oligodendrocytes may be of therapeutic benefit for MS. The β‐hydroxy β‐methylbutyrate (HMB) is a muscle‐building supplement in humans and this study underlines the importance of HMB in stimulating the maturation of OPCs to oligodendrocytes. HMB treatment upregulated the expression of different maturation markers including PLP, MBP, and MOG in cultured OPCs. Double‐label immunofluorescence followed by immunoblot analyses confirmed the upregulation of OPC maturation by HMB. While investigating mechanisms, we found that HMB increased the maturation of OPCs isolated from peroxisome proliferator‐activated receptor β−/− (PPARβ−/−) mice, but not PPARα−/− mice. Similarly, GW6471 (an antagonist of PPARα), but not GSK0660 (an antagonist of PPARβ), inhibited HMB‐induced maturation of OPCs. GW9662, a specific inhibitor of PPARγ, also could not inhibit HMB‐mediated stimulation of OPC maturation. Furthermore, PPARα agonist GW7647, but neither PPARβ agonist GW0742 nor PPARγ agonist GW1929, alone increased the maturation of OPCs. Finally, HMB treatment of OPCs led to the recruitment of PPARα, but neither PPARβ nor PPARγ, to the PLP gene promoter. These results suggest that HMB stimulates the maturation of OPCs via PPARα and that HMB may have therapeutic prospects in remyelination.image
What to make of a Sultan's tear: Phaticity, praise poetry, and social infrastructures in the Sultanate of Oman
Authors: Garvey Bradford 
Published: February 2024

AbstractThe distributive political economy of contemporary Arab Oman yields a status‐differentiated social infrastructure composed of elites who distribute and non‐elites who, in many ways, rely on those distributions. The construction of communicative links within social infrastructures via the performance of sung poetry depends on the phaticity of the link being activated. For Omani poets, different linguistic performance genres telescope the vast social distance between elites who listen and non‐elites who sing in different ways and with different results. Omani poets from the rural north of the country conduct cross‐class social contact—conceptually “vertical” social infrastructural movement—by way of two contrasting genres of Arabic praise poetry: a one‐off request or statement, the solo qasida, and a recognitive, addressive choral form that reciprocally establishes and evaluates such vertical relationships, the 'āzī. I argue that the metapragmatic distinctions that Omani poets draw between these two genres reveal a subtle phatic ideology that allows certain modes of communicative contact to index deeper, cross‐class social ties within grand public performances, while simultaneously reinforcing tacit norms of elite avoidance of non‐elites in everyday social intercourse.

Published: February 2024

AbstractAlthough women make up nearly half of the U.S. workforce, gender role stereotypes persist, and gender roles may relate to how men and women manage work–home boundaries. In this study, we explore gender differences in how employee values (tradition, achievement) translate into role identity salience, and in turn, boundary management preferences and behaviour. With data collected in two waves from 200 employees, we examined how the personal values of tradition and achievement relate differently by gender to role identity salience and in turn, boundary management. We found that men who more strongly value tradition have higher levels of work identity salience and both prefer and create an impermeable boundary around work to prevent intrusion from home. Men who valued tradition more also preferred and crafted a permeable home boundary to allow work intrusion. In contrast, women with higher tradition values reported higher home identity salience, which was associated with preferring segmentation in both work‐to‐home and home‐to‐work directions, and to behaviorally protecting home from work. Contrary to expectations, achievement values did not relate to a boundary management process via role identity salience for either gender. We discuss implications for a more nuanced, values‐driven, and gendered perspective on boundary management.

AbstractThe Sui people living in Guizhou province have a unique ethnic culture and population history due to their long‐time isolation from other populations. To investigate the genetic structure of Sui populations in different regions of Guizhou, we genotyped 89 individuals from four Sui populations using genome‐wide single nucleotide polymorphisms arrays. We analyzed the data using principal component analysis, ADMIXTURE analysis, f‐statistics, qpWave/qpAdm, TreeMix analysis, fineSTRUCTURE, and GLOBETROTTER. We found that Sui populations in Guizhou were genetically homogeneous and had a close genetic affinity with Tai‐Kadai‐speaking populations, Hmong‐Mien‐speaking Hmong, and some ancient populations from southern China. The Sui populations could be modeled as an admixture of 33.5%–37.9% of Yellow River Basin farmer‐related ancestry and 62.1%–66.5% of Southeast Asian‐related ancestry, indicating that the southward expansion of northern East Asian‐related ancestry influenced the formation of the Tai‐Kadai‐speaking Sui people. Future publications of more ancient genomics in southern China could effectively provide further insight into the demographic history and population structure of the Sui people.

AbstractThe most significant driver of adaptive radiation in the New World leaf‐nosed bats (Phyllostomidae) is their remarkably diverse feeding habits, yet there remains a notable scarcity of studies addressing the genetic underpinnings of dietary diversification in this family. In this study, we have assembled a new genome for a representative species of phyllostomid bat, the fringe‐lipped bat (Trachops cirrhosis), and integrated it with eight published phyllostomid genomes, along with an additional 10 genomes of other bat species. Comparative genomic analysis across 10 200 orthologus genes has unveiled that those genes subject to divergent selection within the Phyllostomidae clade are notably enriched in metabolism‐related pathways. Furthermore, we identified molecular signatures of divergent selection in the bitter receptor gene Tas2r1, as well as 14 genes involved in digesting key nutrients such as carbohydrates, proteins, and fats. In addition, our cell‐based functional assays conducted on Tas2r1 showed a broader spectrum of perception for bitter compounds in phyllostomids compared to nonphyllostomid bats, suggesting functional diversification of bitter taste in Phyllostomidae. Together, our genomic and functional analyses lead us to propose that divergent selection of genes associated with taste, digestion and absorption, and metabolism assumes a pivotal role in steering the extreme dietary diversification in Phyllostomidae. This study not only illuminates the genetic mechanisms underlying dietary adaptations in Phyllostomidae bats but also enhances our understanding of their extraordinary adaptive radiation.

AbstractThe canine urinary excretion of florfenicol was evaluated to explore its potential for treating urinary tract infections. Nine healthy male intact purpose‐bred Beagles and four healthy client‐owned dogs each received a single oral dose of florfenicol 20 mg/kg (300 mg/mL parenteral solution) with food. All voluntary urinations were collected for 12 h. Although florfenicol is reportedly bitter tasting, 7/9 Beagles and 4/4 client‐owned dogs completely ingested the florfenicol and were enrolled; salivation (n = 1) and headshaking (n = 3) were observed. The last measured urine florfenicol concentrations were variable: Beagles (0.23–3.19 mcg/mL), Pug (3.01 mcg/mL) English Setter (21.29 mcg/mL), Greyhound (32.68 mcg/mL), and Standard Poodle (13.00 mcg/mL). Urine half‐life was similar for the Beagles and the Pug, 0.75–1.39 h, whereas the half‐life was 1.70–1.82 h for the English Setter, Greyhound, and Standard Poodle. Larger breed dogs exceeded 8 mcg/mL florfenicol (wild‐type cutoff) in their urine at 12 h, whereas the Beagles and Pug had <8 mcg/mL; it is unclear if this is an individual, breed, or size difference. These data suggest oral florfenicol may need to be administered q6‐12h for canine urinary tract infections, but further data are needed (more enrolled dogs, multiple‐dose regimens) before considering clinical trials or breed‐specific differences.

Published: February 2024

SummaryCentral adiposity, which is visceral and subcutaneous adiposity in the abdominal region, is a known risk factor for developing chronic cardiometabolic diseases. Central adiposity can be measured relatively inexpensively using ultrasound. Ultrasound has been shown to be precise and reliable, with measurement accuracy comparable to computed tomography and magnetic resonance. Despite the advantages conferred by ultrasound, widespread adoption has been hindered by lack of reliable standard operating procedures. To consolidate the literature and bring clarity to the use of ultrasound‐derived measures of central adiposity, this review outlines (i) the [patho]physiological importance of central adiposity to cardiometabolic disease risk; (ii) an overview of the history and main technical aspects of ultrasound methodology; (iii) key measurement considerations, including transducer selection, subject preparation, image acquisition, image analysis, and operator training; and (iv) guidelines for standardized ultrasound protocols for measuring central adiposity.

AimThe gut microbiota can influence human behavior. However, due to the massive multiple‐testing problem, research into the relationship between microbiome ecosystems and the human brain faces drawbacks. This problem arises when attempting to correlate thousands of gut bacteria with thousands of brain voxels.MethodsWe performed brain magnetic resonance imaging (MRI) scans on 133 participants and applied machine‐learning algorithms (Ridge regressions) combined with permutation tests. Using this approach, we were able to correlate specific gut bacterial families with brain MRI signals, circumventing the difficulties of massive multiple testing while considering sex, age, and body mass index as confounding factors.ResultsThe relative abundance (RA) of the Selenomonadaceae, Clostridiaceae, and Veillonellaceae families in the gut was associated with altered cerebellar, visual, and frontal T2‐mapping and diffusion tensor imaging measures. Conversely, decreased relative abundance of the Eubacteriaceae family was also linked to T2‐mapping values in the cerebellum. Significantly, the brain regions associated with the gut microbiome were also correlated with depressive symptoms and attentional deficits.ConclusionsOur analytical strategy offers a promising approach for identifying potential brain biomarkers influenced by gut microbiota. By gathering a deeper understanding of the microbiota‐brain connection, we can gain insights into the underlying mechanisms and potentially develop targeted interventions to mitigate the detrimental effects of dysbiosis on brain function and mental health.

Published: February 2024

AbstractBackgroundValganciclovir is approved for cytomegalovirus prophylaxis in pediatrics using the Pescovitz algorithm. There are reports of valganciclovir overdoses in children with low body surface area and overestimated creatinine clearance utilizing this algorithm. This study compared the incidence of neutropenia and cytomegalovirus infection between the Pescovitz and weight‐based dosing algorithms.MethodsA single‐center retrospective chart review from January 2010 to September 2018 was performed on pediatric heart, liver, and kidney transplant recipients, who received valganciclovir. Data were collected from the initiation of valganciclovir prophylaxis to 30 days after discontinuation. The primary objective was the incidence of neutropenia in patients receiving valganciclovir dosed by the Pescovitz versus weight‐based dosing algorithms.ResultsThis study included 187 pediatric transplant recipients who received valganciclovir dosed via the Pescovitz (62 recipients) or weight‐based dosing algorithms (125 recipients). The incidence of neutropenia was higher in the Pescovitz (69.4%) compared to the weight‐based dosing group (53.6%; p = .04) including moderate and severe neutropenia. Cytomegalovirus viremia was not significantly different between the two groups and occurred in 4.8% of the Pescovitz group compared to 2.4% of the weight‐based group (p = .4).ConclusionsThe incidence of neutropenia was greater in recipients receiving valganciclovir dosed via the Pescovitz algorithm compared to the weight‐based dosing. There were no significant differences in regard to cytomegalovirus viremia or disease between the two groups.

Published: February 2024

AbstractBackgroundSmall‐for‐size syndrome (SFSS) in pediatric liver transplant recipients, particularly those weighing less than 10 kg, is rare. This report describes a case of a 15‐month‐old whole liver transplant recipient who suffered SFSS, and systematic literature review was performed to identify outcomes of such cases and potential risk factors for SFSS.Case PresentationA 15‐month‐old toddler with a history of biliary atresia underwent a deceased donor whole liver transplant. The graft weighed 160 g, resulting in a graft‐to‐recipient weight ratio (GRWR) of 1.6%. The post‐operative course was complicated by SFSS, characterized by massive ascites causing hemodynamic instability and compromised hepatic artery flow. Pharmacological intervention with octreotide was initiated, and the patient eventually recovered.ConclusionIn small pediatric recipients, especially those weighing less than 10 kg, the native liver body weight ratio (LBWR) is significantly higher. When selecting an appropriately sized graft for these recipients, this higher ratio should be taken into consideration. The literature review suggests that a GRWR of less than 2% is associated with a higher incidence of small‐for‐size syndrome in small pediatric recipients weighing less than 10 kg.
Mono‐MVS: textureless‐aware multi‐view stereo assisted by monocular prediction
Authors: Fu Yuanhao , Zheng Maoteng , Chen Peiyu , Liu Xiuguo 
Published: February 2024

AbstractThe learning‐based multi‐view stereo (MVS) methods have made remarkable progress in recent years. However, these methods exhibit limited robustness when faced with occlusion, weak or repetitive texture regions in the image. These factors often lead to holes in the final point cloud model due to excessive pixel‐matching errors. To address these challenges, we propose a novel MVS network assisted by monocular prediction for 3D reconstruction. Our approach combines the strengths of both monocular and multi‐view branches, leveraging the internal semantic information extracted from a single image through monocular prediction, along with the strict geometric relationships between multiple images. Moreover, we adopt a coarse‐to‐fine strategy to gradually reduce the number of assumed depth planes and minimise the interval between them as the resolution of the input images increases during the network iteration. This strategy can achieve a balance between the computational resource consumption and the effectiveness of the model. Experiments on the DTU, Tanks and Temples, and BlendedMVS datasets demonstrate that our method achieves outstanding results, particularly in textureless regions.

Published: February 2024

AbstractDeveloping multifunctional nanomaterials with distinct photochemical properties, such as high quantum yield, improved photostability, and good biocompatibility is critical for a wide range of biomedical applications. Motivated by this, we designed and synthesized a dansyl‐tagged xanthate‐based capping agent (DX) for the synthesis of fluorescent silver nanoparticles (AgNPs). The capping agent DX was characterized by 1H and 13C‐NMR, LC–MS, and FT‐IR. The synthesized DX‐capped fluorescent AgNPs were thoroughly characterized by UV–visible spectroscopy, fluorescence spectroscopy, field emission scanning electron microscope (FE‐SEM), transmission electron microscope (TEM), dynamic light scattering (DLS), and zeta potential. The fluorescent AgNPs showed distinct surface plasmon resonance absorption at λmax = 414 nm, fluorescence at λmax = 498 nm, quantum yield = 0.24, zeta potential = +18.6 mV, average size = 18.2 nm. Furthermore, the biological activity of the fluorescent AgNPs was validated by its interaction with the most abundant protein in the blood, that is, BSA (Bovine serum albumin) and HSA (Human serum albumin) with binding constant of 2.34 × 104 M−1 and 2.14 × 104 M−1 respectively. Interestingly, fluorescence resonance energy transfer (FRET) was observed between the fluorescent AgNPs and BSA/HSA with a FRET efficiency of 77.23% and 56.36%, respectively, indicating strong interaction between fluorescent AgNPs and BSA/HSA.
