B‐1 lymphocytes in adipose tissue as innate modulators of inflammation linked to cardiometabolic disease
Authors: Meher Akshaya K. , McNamara Coleen A. 
Published: May 2024

SummaryFat is stored in distinct depots with unique features in both mice and humans and B cells reside in all adipose depots. We have shown that B cells modulate cardiometabolic disease through activities in two of these key adipose depots: visceral adipose tissue (VAT) and perivascular adipose tissue (PVAT). VAT refers to the adipose tissue surrounding organs, within the abdomen and thorax, and is comprised predominantly of white adipocytes. This depot has been implicated in mediating obesity‐related dysmetabolism. PVAT refers to adipose tissue surrounding major arteries. It had long been thought to exist to provide protection and insulation for the vessel, yet recent work demonstrates an important role for PVAT in harboring immune cells, promoting their function and regulating the biology of the underlying vessel. The role of B‐2 cells and adaptive immunity in adipose tissue biology has been nicely reviewed elsewhere. Given that, the predominance of B‐1 cells in adipose tissue at homeostasis, and the emerging role of B‐1 cells in a variety of disease states, we will focus this review on how B‐1 cells function in VAT and PVAT depots to promote homeostasis and limit inflammation linked to cardiometabolic disease and factors that regulate this function.
Allochronic reproductive cycles among colonies of the Caribbean octocoral Antillogorgia americana
Authors: Lasker Howard R. , Calderón Julio 
Published: May 2024

AbstractThe reproductive biology of the branching octocoral Antillogorgia americana was studied at a site on the Caribbean coast of Panama in 1990–1991 by examining the reproductive status of 11 colonies across 14 months. Colonies were gonochoric. The presence of large and mature eggs or spermaries was allochronic across colonies and months, with peak gonad volumes occurring in months ranging from October through May. Reproductive effort varied between branches on a colony, with variation between branches and branchlets accounting for 25% of the random variation between polyps. Branchlets at the tip of the colony had fewer mature eggs than those lower on the branch, and polyps at the tips of the branchlets had fewer still. Although the simultaneous release of eggs and sperm is critical to reproductive success, the lack of synchrony among colonies on the scale of months may reflect less need for all colonies to spawn in a single event among abundant species that release large numbers of gametes. Such a strategy also spreads the risk of reproductive failure due to environmental conditions during any single month. The presence of multiple spawning episodes can also drive the reproductive isolation of populations and may reflect the presence of cryptic species within the taxon. Studies of reproductive timing can be an important adjunct in identifying variation in life history strategies as well as assessing the validity of species boundaries.

Published: May 2024

AbstractNanostructured Y‐TZP samples with Non‐Homogeneous Yttria Distribution (NNHYD) were prepared by mixing co‐precipitated 3Y‐TZP powder (Tosoh TZ‐3Y) with yttria‐free monoclinic powder (Tosoh TZ‐0), yielding an overall yttria content of 2 mol%. The cyclic fatigue behavior of NNHYD was evaluated by Step‐Stress Accelerated Life Testing (SSALT) and mechanical cycling in a biaxial flexural strength test (BFST) setup and compared to Conventional Submicrometric 3Y‐TZP (CS). Physical, structural, microstructural, and mechanical characterizations of all groups were also evaluated and compared before and after artificial aging in autoclave. NNHYD presented a higher capacity for damage accumulation and maintenance of phase transformation potential than CS, associated with elevated resistance to the propagation of Low‐Temperature Degradation (LTD). A nanostructured 3Y‐TZP surface layer introduced in NNHYD by dip coating (DC‐NNHYD) improved resistance to LTD at the cost of reduced reliability under cyclic fatigue by increasing the stability of the tetragonal phase. This surface alteration highlights the impact of surface properties on mechanical performance. The results of this study present practical possibilities to help achieve the ideal balance between strength, toughness, and LTD resistance to improve the lifetime of zirconia‐based biomaterials.

Published: May 2024

AbstractUtilizing a high‐entropy strategy, we propose a novel approach for synthesizing (Na0.4K0.1Bi0.5)TiO3 (NKBT)‐based ceramics endowed with exceptional dielectric stability at elevated temperatures. The high‐entropy effect induces a random tilt in the oxygen octahedra of NKBT ceramics, leading to a broad dielectric response characterized by diffuse phase transitions. By weakening the dielectric abnormal peak at Ts of BNT, the dielectric stability of high‐entropy NKBT ceramics is significantly enhanced. Notably, at 100 kHz, the temperature stability range of (Na0.4K0.1Bi0.5)(Ti0.65Zr0.1Sn0.15Hf0.1)O3, synthesized through the traditional solid reaction method, reaches an impressive 311°C, surpassing undoped NKBT by 257%. This significant enhancement underscores the feasibility of our high‐entropy strategy in improving dielectric performance. Our work demonstrates a straightforward and cost‐effective method for significantly improving the dielectric temperature stability of NKBT ceramics.
Evaluation of breeding strategies to reduce the inbreeding rate in the Friesian horse population: Looking back and moving forward

Published: May 2024

AbstractIn the past, small population sizes and unequal ancestor contributions have resulted in high inbreeding rates (ΔF) in the Friesian horse. Two decades ago, the studbook implemented a mating quota and started publishing individual kinships and reduced ΔF below 1% per generation. However, since then, the breeding population size has decreased and this raises the question whether current breeding strategies are sufficient to keep ΔF below desired rates. The aim of this study was to (1) reflect on past inbreeding trends and their main determinants, using pedigree analysis and (2) evaluate the effectiveness of the current and additional breeding strategies using stochastic simulations. We estimated the current ΔF (2013–2022) at 0.72% per generation. While the total contribution of the top 10 sires to the number of offspring per year has decreased from 75% in 1980 to 35% in 2022, this was mainly due to an increased number of approved studbook sires, and not due to more equalized contributions among sires. Of the simulated breeding strategies, selecting only breeding stallions with a below average mean kinship (i.e., “mean kinship selection”) was most effective to decrease ΔF (from 0.66% to 0.33%). Increasing the number of breeding sires only had an effect when also a mating quota was applied. However, its effect remained limited. For example, a ~1.5 fold increase, combined with a mating quota of 80 offspring per sire per year, reduced ΔF from 0.55% to 0.51%. When increasing the number of breeding mares, a practically unfeasible large increase was needed for a meaningful reduction in ΔF (e.g. twice as many mares were needed to reduce ΔF from 0.66% to 0.56%). Stratified mating quotas, a novel approach in which we assigned each sire a mating quota (of 60, 80, 100 or 120 offspring per year) based on its mean kinship to recently born foals, resulted in a lower ΔF (0.43%) than a general mating quota of 90 offspring per sire per year (0.55%). Overall, while the current ΔF is below 1%, we recommend to implement additional strategies to further reduce ΔF below 0.5% in the Friesian horse population. For this breed and similar populations, we recommend to focus on breeding strategies based on kinship levels to effectively reduce ΔF.
Species boundaries of the whiptail catfish Rineloricaria (Siluriformes: Loricariidae) from the Paraíba do Sul River drainage, southeastern Brazil, with species redescriptions and description of a new species
Authors: Mejia Eduardo , Buckup Paulo A. 
Published: May 2024

AbstractSpecies of the catfish genus Rineloricaria are common in the Paraíba do Sul River basin, in southeastern Brazil; here we present a revision of the taxonomic diversity and geographic distribution of the species of the genus inhabiting the basin, based on novel morphologic and molecular data. Five species delimitation methods based on cytochrome C oxidase subunit 1 nucleotide sequences yielded comparable molecular operational taxonomic units. The automatic barcode gap discovery, assemble species by automatic partitioning, barcode index number, and Bayesian implementation of the Poisson tree process methods supported the recognition of five evolutionary lineages. These taxonomic units were assigned to the previously described Rineloricaria nigricauda, Rineloricaria steindachneri, Rineloricaria zawadzkii, and Rineloricaria nudipectoris, and an additional undescribed species. R. zawadzkii was further divided into two intraspecific geographically structured lineages using the generalized mixed Yule coalescent delimitation method. A maximum likelihood phylogenetic analysis revealed that the five lineages from the Paraíba do Sul have closer relationships to different species from southern and southeastern Brazil (Ribeira de Iguape, Lagoa dos Patos, Uruguay, Paraguay, and Parana river basins) than to each other. Based on the analysis of lectotypes, recently collected material, and specimens from ichthyological collections, the poorly described R. nigricauda and R. steindachneri are redescribed following current descriptive standards. The undescribed species from the middle and upper Paraíba do Sul River basin is formally described. The description of a new species, along with the description of species boundaries in R. nigricauda and R. steindachneri, contributes to the knowledge of the ichthyofauna of the Paraíba do Sul River basin and adjacent coastal drainages of southeastern Brazil. An identification key for the species of Rineloricaria occurring in the Paraíba do Sul River basin is provided.

AbstractThere is an increasing demand for plant‐based burger patties owing to the health and sustainability issues raised from the consumption of meat. This study aimed to develop plant‐based burger patties from pea protein isolates (PPIs) and barnyard millet flour (BMF) through high‐moisture extrusion cooking. The extrudates for plant‐based burger patties were developed with a blend ratio of 90:10 PPIs:BMF with different screw speeds ranging from 40 to 120 rpm. The extrudates produced with different screw speeds were analyzed, followed by the analysis of the plant‐based burger patties. Commercial plant‐based burger patties were used as a control. The optimized plant‐based burger patties were then stored in aerobic or vacuum packaging for 12 days under refrigerated condition and analyzed. The optimized extrudates produced using screw speed of 80 rpm displayed moderate water absorption index (3.33%), high hardness (4143–4390 g), and high adhesion (0.47 mJ). The plant‐based burger patties produced using the optimized extrudates had 2006–2608‐g hardness, 0.17 cohesiveness, and 6.70% cooking loss. In comparison to aerobic packaging, the plant‐based burger patties stored in vacuum packaging demonstrated lower cooking loss (8.46%), moisture content (18.03%), total color difference (3.02), and total plate count (8.65 log10 cfu/g) after 12 days of refrigerated storage. The protein content of plant‐based burger patties was not affected throughout the refrigerated storage. This shows the potential of PPIs and BMF mixtures as meat analogue ingredients and the suitability of vacuum packaging for the storage of plant‐based meat.

AbstractBackground and AimFalse positives (FPs) pose a significant challenge in the application of artificial intelligence (AI) for polyp detection during colonoscopy. The study aimed to quantitatively evaluate the impact of computer‐aided polyp detection (CADe) systems' FPs on endoscopists.MethodsThe model's FPs were categorized into four gradients: 0–5, 5–10, 10–15, and 15–20 FPs per minute (FPPM). Fifty‐six colonoscopy videos were collected for a crossover study involving 10 endoscopists. Polyp missed rate (PMR) was set as primary outcome. Subsequently, to further verify the impact of FPPM on the assistance capability of AI in clinical environments, a secondary analysis was conducted on a prospective randomized controlled trial (RCT) from Renmin Hospital of Wuhan University in China from July 1 to October 15, 2020, with the adenoma detection rate (ADR) as primary outcome.ResultsCompared with routine group, CADe reduced PMR when FPPM was less than 5. However, with the continuous increase of FPPM, the beneficial effect of CADe gradually weakens. For secondary analysis of RCT, a total of 956 patients were enrolled. In AI‐assisted group, ADR is higher when FPPM ≤ 5 compared with FPPM > 5 (CADe group: 27.78% vs 11.90%; P = 0.014; odds ratio [OR], 0.351; 95% confidence interval [CI], 0.152–0.812; COMBO group: 38.40% vs 23.46%, P = 0.029; OR, 0.427; 95% CI, 0.199–0.916). After AI intervention, ADR increased when FPPM ≤ 5 (27.78% vs 14.76%; P = 0.001; OR, 0.399; 95% CI, 0.231–0.690), but no statistically significant difference was found when FPPM > 5 (11.90% vs 14.76%, P = 0.788; OR, 1.111; 95% CI, 0.514–2.403).ConclusionThe level of FPs of CADe does affect its effectiveness as an aid to endoscopists, with its best effect when FPPM is less than 5.

Published: May 2024

AbstractBackground and AimCenicriviroc (CVC) is a CCR2/CCR5 antagonist that has been shown to be effective in the treatment of inflammatory and fibrotic diseases. Our study evaluated its efficacy in colitis.MethodsMouse models of DSS‐induced acute and chronic colitis were established. The efficacy of CVC in colitis was assessed by disease activity index (DAI) scores, histological assessment of inflammation and fibrosis, and expression assays of key molecules. In in vitro experiments, HT29 cell line was exposed to TNFα to study inflammatory signaling in intestinal epithelial cells. CCD‐18Co colonic myofibroblasts and human primary colonic fibroblasts were activated by TGFβ1 to mimic fibroblast activation.ResultsIn HT29 cells, CVC significantly reduced mRNA expression of CCL5 (P < 0.01) but had no effect on CCL2. Furthermore, CVC reduced downstream CX3CL1 (P < 0.01) and TNFα (P < 0.05) expression, thereby inhibiting inflammatory progression. In acute colitis mice, CVC significantly reduced DAI scores and serum TNFα levels (P < 0.05) and attenuated colonic inflammation as shown by HE staining. Meanwhile, CVC had no adverse effects on the liver, heart, and kidney of mice. On the other hand, in cellular models of chronic colitis, CVC decreased the expression of fibrosis markers, including FN, CTGF, α‐SMA, and MMP9, and inhibited TGFβ1‐induced fibrotic activation (P < 0.01). In addition, CVC attenuated colonic fibrosis in chronic colitis mice. Moreover, CVC significantly promoted autophagy, which contributed to its regulation of inflammation.ConclusionsCVC significantly inhibited inflammation through CCL5/CCR5 signaling without damaging vital organs and suppressed fibrotic activation in chronic colitis, suggesting its great potential to relieve colonic inflammation and fibrosis.

Published: May 2024

AbstractBackgroundAnalysing the literature about the reproductive anatomy on New World Primates, one can see the need of standardisation on the description methods and, more importantly, the lack of detailed information. The problem is aggravated by the difficult access to specimens of the endangered species such as Brachyteles sp. This paper's objective was to extend knowledge on the male reproductive anatomy of these primates. The testis and funiculus spermaticus of Brachyteles are described in detail.MethodsWe utilised one individual of Brachyteles arachnoides, two hybrids (B. arachnoides × Brachyteles hypoxanthus) and photographs of the testis of a third fresh specimen of a hybrid individual.ResultsThe septum formed by tunica dartos adheres to the testis and separates the scrotum in two testicular cavities. Passed the spermatic cord, the external spermatic fascia continues with the tunica dartos, covering the cranial half of the testis. The fascia cremasterica divides itself in bundles of fibres and forms loops around the testicles creating a sac like structure that seems to be unique among Neotropical Primates. The appendix testis is described for the first time in platyrrhini. It is presented as a sessile structure in the extremitas capitata of the testis. Previous literature on the reproductive anatomy of platyrrhini is limited. Despite that, it can be said that the large size and volume of the testis, and complex structure of the cremaster, could consist of a heat loss reduction strategy in cold and humid forest environments.ConclusionsExcept for the larger size of the testicles in hybrid individuals, no other significant morphological differences were found between B. arachnoides and hybrids (B. arachnoides × B. hypoxanthus).
Trajectories of nursing hours over the course of hospitalization and estimated additional nurse staffing requirements to reduce the length of stay
Authors: Kim Shin‐Ae , Cho Sung‐Hyun 
Published: May 2024

AbstractPurposeThe aims of this study are to examine the trajectories of nursing hours per patient day (NHPPD) over the course of hospitalization according to the patient's length of stay (LOS) and to estimate changes in the total nursing hours during hospitalization, average NHPPD, and the number of nurses additionally required when the LOS was reduced by 1 day.DesignThis retrospective longitudinal study analyzed patient data collected from a tertiary university hospital located in Seoul, South Korea. The study sample included 11,316 inpatients who were discharged between September 1 and October 31, 2022.MethodsNHPPD over the course of each patient's hospitalization was estimated using the total score of the Korean Patient Classification System‐1 (KPCS‐1), which nurses evaluated and recorded every day from admission to discharge. The NHPPD trajectories were examined using linear mixed models to analyze repeated KPCS‐1 measurements and control for the effects of patient characteristics. The changes in the average NHPPD when LOS was reduced by 1 day were estimated using maximum and minimum estimations. The impact of a 1‐day reduction in LOS on staffing requirements was calculated as the number of nurses additionally required to work each shift and to be hired.FindingsThe average LOS was 5.6 days, and the short (1–6 days) and medium (7–14 days) LOS groups accounted for 78.9% and 14.3% of patients, respectively. The NHPPD trajectories showed a “rise‐peak‐decline” pattern. Patients in the short LOS group received the most NHPPD on day 1 (day of admission) or day 2, whereas the NHPPD for patients in the medium LOS group peaked on days 3–6. After peaking, the NHPPD tended to decrease toward the end of hospitalization, with the least NHPPD on the day of discharge, followed by the day before discharge. When LOS was reduced by 1 day, the average NHPPD was estimated to increase by 7.7–50.0% in the maximum estimation, and 0.9–12.5% in the minimum estimation. In response to a 1‐day reduction, 1.10–7.44 nurses were additionally required to care for 100 patients each shift and 5.28–35.70 additional nurses needed to be hired in the maximum estimation. In the minimum estimation, these values were 0.13–1.85 additional nurses per shift and 0.65–8.90 additional nurses to be hired, respectively.ConclusionsSince NHPPD exhibited a “rise‐peak‐decline” trajectory, reducing the LOS by 1 day was estimated to increase the average NHPPD and lead to additional staffing requirements. The additional nurse requirement for a 1‐day reduction was not constant; instead, it increased with each day subtracted from an already shorter LOS.Clinical RelevanceSufficient nurse staffing is necessary to provide increased NHPPD as a result of shortened LOS. Changes in the LOS should be considered when determining nurse staffing requirements.

AbstractBackgroundHypercoagulability has been documented in cats with cardiac disease. However, hemostatic parameters, including viscoelastic coagulation monitoring (VCM) have not been reported in cats with arterial thromboembolism (ATE).Hypothesis/ObjectivesCompare VCM parameters in cats with acute cardiogenic ATE and in control cats.AnimalsSixteen cats with ATE and 30 control cats.MethodsMulticenter university‐based prospective study. Cardiogenic ATE was diagnosed based on physical examination and by ultrasonographically‐diagnosed left atrial enlargement. Viscoelastic coagulation monitor analysis, CBC, serum biochemistry profile and coagulation profile were performed at admission in cats with ATE. Analysis from healthy control cats was performed using blood collected by direct venipuncture. Our objective was comparison of VCM parameters clot time (CT), clot formation time (CFT), alpha angle (Angle), maximum clot formation (MCF), amplitude at 10 and 20 minutes (A10 and A20, respectively) and clot lysis index at 30 and 45 minutes (LI30 and LI45, respectively) between ATE and control cats.ResultsCats with ATE had a decreased angle compared to control cats, with a median (range) of 43° (30‐48°) compared to 47° (14‐59°; P = .01). The parameters A10, A20 and MCF were decreased in ATE cats compared to control cats with a median (range) of 19 units (8–32) compared to 22 units (6–38), 24.5 units (11‐40) compared to 29 units (10‐47) and 29.5 units (13‐44) compared to 33.5 units (14‐53), respectively (P = .01, .01 and .01, respectively). The parameters CT, CFT, LI30 and LI45 were similar between groups (P = .22, .09, .62 and .34, respectively).Conclusions and Clinical ImportanceCats with cardiogenic ATE cats have VCM parameters consistent with hypocoagulability compared with healthy cats.
