Early Origins of Divergent Patterns of Morphological Evolution on the Mammal and Reptile Stem-Lineages

Abstract The origin of amniotes 320 million years ago signaled independence from water in vertebrates and was closely followed by divergences within the mammal and reptile stem lineages (Synapsida and Reptilia). Early members of both groups had highly similar morphologies, being superficially “lizard-like” forms with many plesiomorphies. However, the extent to which they might have exhibited divergent patterns of evolutionary change, with the potential to explain the large biological differences between their living members, is unresolved. We use a new, comprehensive phylogenetic dataset to quantify variation in rates and constraints of morphological evolution among Carboniferous–early Permian amniotes. We find evidence for an early burst of evolutionary rates, resulting in the early origins of morphologically distinctive subgroups that mostly persisted through the Cisuralian. Rates declined substantially through time, especially in reptiles. Early reptile evolution was also more constrained compared with early synapsids, exploring a more limited character state space. Postcranial innovation in particular was important in early synapsids, potentially related to their early origins of large body size. In contrast, early reptiles predominantly varied the temporal region, suggesting disparity in skull and jaw kinematics, and foreshadowing the variability of cranial biomechanics seen in reptiles today. Our results demonstrate that synapsids and reptiles underwent an early divergence of macroevolutionary patterns. This laid the foundation for subsequent evolutionary events and may be critical in understanding the substantial differences between mammals and reptiles today. Potential explanations include an early divergence of developmental processes or of ecological factors, warranting cross-disciplinary investigation.

Association Between Body Mass Index and Morbidity and Mortality During Hospitalization After Trauma

BACKGROUND: Literature suggests that unhealthy body mass index is a risk factor for adverse clinical outcomes. OBJECTIVES: To study the association between unhealthy body mass index and morbidity and mortality after trauma using the 2016 American College of Surgeons Trauma Quality Improvement Program database. METHODS: A retrospective review was conducted comparing the normal weight control group to the underweight, overweight, obese, severely obese, and morbidly obese groups for differences in demographic factors, injury severity score, comorbidities, length of stay, and complications. RESULTS: Underweight, overweight, obese, severely obese, and morbidly obese body mass indexes, in comparison to normal weight body mass index, were associated with a higher probability of developing at least one complication after trauma. Additionally, we observed a J-shaped curve when analyzing body mass index and mortality, suggesting that both high and low body mass indexes are positively associated with mortality. In fact, morbidly obese patients had the highest mortality rate, followed by underweight patients (p < .001). Interestingly, however, multivariate logistic regression demonstrated that, compared with normal weight body mass index, overweight and obese body mass indexes were independently associated with 9.6% and 10.5% lower odds of mortality, respectively (p < .001 and p = .001). CONCLUSION: Irrespective of preexisting comorbidities, injury severity score, and mechanism of injury, underweight, overweight, obese, severely obese, and morbidly obese body mass indexes were independently associated with higher risks of morbidity, whereas overweight and obese body mass indexes were associated with lower mortality risks. These findings emphasize the complex relationship between body mass index and clinical outcomes for trauma patients.
The regulatory role of CARBON STARVED ANTHER-mediated photoperiod-dependent male fertility in rice

Abstract Environmental signals, especially daylength, play important roles in determining fertility in photoperiod-sensitive genic male sterile (PGMS) lines that are critical to sustain production of high-yielding hybrid rice (Oryza sativa) varieties. However, the mechanisms by which PGMS lines perceive changes in photoperiod and transmit those signals to elicit downstream effects are not well understood. In this study, we compared the transcriptomes from the leaves and anthers of carbon starved anther (csa), a PGMS line, to wild-type (WT) tissues under different photoperiods. Components of circadian clock in the leaves, including Circadian Clock-Associated 1 and Pseudo-Response Regulator (PRR95), played vital roles in sensing the photoperiod signals. Photoperiod signals were weakly transduced to anthers, where gene expression was mainly controlled by the CSA allele. CSA played a critical role in regulating sugar metabolism and cell wall synthesis in anthers under short-day conditions, and transcription of key genes inducing csa-directed sterility was upregulated under long-day (LD) conditions though not to WT levels, revealing a mechanism to explain the partial restoration of fertility in rice under LD conditions. Eight direct targets of CSA regulation were identified, all of which were genes involved in sugar metabolism and transport (cell wall invertases, SWEETs, and monosaccharide transporters) expressed only in reproductive tissues. Several hub genes coordinating the effects of CSA regulation were identified as critical elements determining WT male fertility and further analysis of these and related genes will reveal insights into how CSA coordinates sugar metabolism, cell wall biosynthesis, and photoperiod sensing in rice anther development.
Evaluation of the human hazard of the liver and lung tumors in mice treated with permethrin based on mode of action

Abstract The non-genotoxic synthetic pyrethroid insecticide permethrin produced hepatocellular adenomas and bronchiolo-alveolar adenomas in female CD-1 mice, but not in male CD-1 mice or in female or male Wistar rats. Studies were performed to evaluate possible modes of action (MOAs) for permethrin-induced female CD-1 mouse liver and lung tumor formation. The MOA for liver tumor formation by permethrin involves activation of the peroxisome proliferator-activated receptor alpha (PPARα), increased hepatocellular proliferation, development of altered hepatic foci, and ultimately liver tumors. This MOA is similar to that established for other PPARα activators and is considered to be qualitatively not plausible for humans. The MOA for lung tumor formation by permethrin involves interaction with Club cells, followed by a mitogenic effect resulting in Club cell proliferation, with prolonged administration producing Club cell hyperplasia and subsequently formation of bronchiolo-alveolar adenomas. Although the possibility that permethrin exposure may potentially result in enhancement of Club cell proliferation in humans cannot be completely excluded, there is sufficient information on differences in basic lung anatomy, physiology, metabolism, and biologic behavior of tumors in the general literature to conclude that humans are quantitatively less sensitive to agents that increase Club cell proliferation and lead to tumor formation in mice. The evidence strongly indicates that Club cell mitogens are not likely to lead to increased susceptibility to lung tumor development in humans. Overall, based on MOA evaluation it is concluded that permethrin does not pose a tumorigenic hazard for humans, this conclusion being supported by negative data from permethrin epidemiological studies.
Expression of serum autophagy-related protein P62 in patients with severe pancreatitis and its correlation with prognosis.

OBJECTIVE This study was designed to investigate the expression of serum autophagy-related protein P62 in patients with severe acute pancreatitis (AP) and its correlation with prognosis. METHODS Eighty patients with AP treated in the First Affiliated Hospital of Gannan Medical University from January 2020 to January 2021 were enrolled as study subjects in this retrospective analysis, and they were placed into the mild AP group (n=52) or the severe AP group (n=28). According to clinical outcomes, these 80 patients were divided into a good prognosis group (GP group, n=51, surviving without serious complications such as organ failure) and a poor prognosis group (PP group, n=29, death or developing organ failure). The differences in C-reactive protein (CRP), P62 and the Acute Physiology and Chronic Health Evaluation II (APACHE-II) were compared upon admission. The changes of CRP, P62 and APACHE-II within 1-7 h after admission were dynamically analyzed in the two groups. Spearman correlation analysis was performed to explore the correlation between P62 and APACHE-II scores, and the receiver operating characteristic (ROC) curve of P62 related to poor AP outcome was plotted. RESULTS CRP, P62 and APACHE-II in the mild AP group were significantly higher than those in the severe AP group, and these in the PP group were also significantly higher than those in the GP group (P<0.05). Dynamic monitoring showed that within 1-7 h after admission, CRP, P62, and APACHE-II in the severe AP group were significantly higher than those in the mild AP group (P<0.05), and these in the PP group were significantly higher than those in the GP group (P<0.05). Spearman correlation analysis showed that P62 level was significantly positively correlated with both CRP and APACHE-II (r=0.9331, r=0.9500, P<0.0001). ROC curve showed that AUC of P62 was 0.9570 in AP patients with poor prognosis (95% CI=0.8939-1.000, P<0.0001). CONCLUSION Serum autophagy-related protein P62 was closely related to the condition and prognosis of AP patients, and P62 could be used as a potential indicator to assess the condition and prognosis of AP patients.
Simultaneous relaxometry and morphometry of human brain structures with 3D magnetic resonance fingerprinting: a multicenter, multiplatform, multifield-strength study

Abstract Relaxation times and morphological information are fundamental magnetic resonance imaging-derived metrics of the human brain that reflect the status of the underlying tissue. Magnetic resonance fingerprinting (MRF) enables simultaneous acquisition of T1 and T2 maps inherently aligned to the anatomy, allowing whole-brain relaxometry and morphometry in a single scan. In this study, we revealed the feasibility of 3D MRF for simultaneous brain structure-wise morphometry and relaxometry. Comprehensive test–retest scan analyses using five 1.5-T and three 3.0-T systems from a single vendor including different scanner types across 3 institutions demonstrated that 3D MRF-derived morphological information and relaxation times are highly repeatable at both 1.5 T and 3.0 T. Regional cortical thickness and subcortical volume values showed high agreement and low bias across different field strengths. The ability to acquire a set of regional T1, T2, thickness, and volume measurements of neuroanatomical structures with high repeatability and reproducibility facilitates the ability of longitudinal multicenter imaging studies to quantitatively monitor changes associated with underlying pathologies, disease progression, and treatments.
miR-30a-3p can inhibit the proliferation and promote the differentiation of chicken primary myoblasts

ABSTRACT 1. Chicken muscle is an important factor in meat quality and its development is controlled by a complex regulatory network. 2. The following study examined the expression of miR-30a-3p in Gushi chicken breast muscle tissue and found that it was differentially expressed at different embryonic stages, reaching a peak in the 14-day-old embryo (E14). 3. The effect of miR-30a-3p on chicken primary myoblasts (CPMs) was explored. Results from both cell counting kit-8 (CCK-8) and 5-ethynyl-2’-deoxyuridine (EdU) showed that this can inhibit the proliferation of myoblasts, and through cell cycle experiments, the inhibition of myoblast proliferation was found, which may be due to G0/G1 arrest in the cell cycle. 4. The effect of miR-30a-3p on the differentiation of myoblasts was studied. The results showed that miR-30a-3p can promote the expression of MYOD, myogenin (MYOG), and myosin heavy chain (MYHC) genes to promote the differentiation of myoblasts. Through MYHC protein immunofluorescence experiments, it was found that miR-30a-3p can effectively increase the area of myotubes. 5. Finally, mRNA transcriptome data was analysed, which showed that miR-30a-3p has 51 potential target genes. Among them, forkhead box O3 (FOXO3), ankyrin repeat domain 1 (ANKRD1), and insulin-induced 1 (INSIG1) genes were differentially expressed at different developmental stages and were enriched in Gene Ontology (GO) terms, such as cell differentiation and cellular developmental process. The data showed that tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein gamma (YWHAG), BUB1 mitotic checkpoint serine/threonine kinase (BUB1), and growth arrest and DNA damage-inducible 45 (GADD45) genes were enriched in the cell cycle pathway. 6. It can be speculated that miR-30a-3p plays roles through these genes in myoblast development. This research provides information for further improving knowledge of the chicken muscle development regulation network.
Four Questions Nurses Can Ask to Predict PTSD 1 Year After a Motor Vehicle Crash

BACKGROUND: The role of nurses in screening for posttraumatic stress disorder is crucial in trauma units. OBJECTIVES: To create and evaluate an easy and brief tool for nurses to predict chronic posttraumatic stress disorder 1 year after a motor vehicle crash. METHODS: We performed a 1-year follow-up multicenter study from 2007 to 2015, including 274 patients injured in a motor vehicle crash who were hospitalized in an orthopedic trauma unit. Nurses administered the DEPITAC questionnaire. Posttraumatic stress disorder was measured by the Post-Traumatic Stress Disorder Checklist of symptoms during the first year following the crash. A multivariable logistic regression model was implemented to select items significantly associated with posttraumatic stress disorder to improve the DEPITAC questionnaire. Predictive performance to predict posttraumatic stress disorder 1 year after the motor vehicle crash was examined for these different models. RESULTS: Of 274 patients studied, a total of 75.9% completed the questionnaire at 1 year of follow-up. We found that only two questions and two simple elements of the patient's medical record (other injury or a person dying during the crash, perception of vital threat, number of children, and length of stay in trauma) predicted posttraumatic stress disorder 1 year after a motor vehicle crash. CONCLUSIONS: The brevity of this evaluation, simple scoring rules, and screening test performance suggest that this new screening tool can be easily administered in the acute care setting by nurses.
Association between four-limb blood pressure differences and arterial stiffness: a cross-sectional study

ABSTRACT Objectives Although inter-arm blood pressure difference (IAD) and inter-ankle blood pressure difference (IAND) have been shown to be associated with cardiovascular disease, controversy remains. In this study, we investigated the prevalence of IAD and IAND as well as the correlation with arterial stiffness and systolic blood pressure in a large number of the Chinese population. Methods The four-limb blood pressure, IAD, IAND, brachial-ankle pulse wave velocity (baPWV) and ankle-brachial index (ABI) of 12,176 participants have been measured. Multivariate logistic regression analysis was used to analyze the relationship of the increase in IAD/IAND with arterial stiffness and blood pressure. Reporting adheres to the STROBE guidelines. Results In 12,176 participants, 1832 (15%) subjects had an IAD≥10 mmHg, 663 (5%) had an IAD≥15 mmHg, and 291 (2%) had an IAD≥20 mmHg. Correspondingly, 4548 (37%) had an IAND≥10 mmHg, 2706 (22%) had an IAND≥15 mmHg, and 1706 (14%) had an IAND≥20 mmHg. baPWV was significantly higher in those with an IAD≥10 mmHg (1881 ± 487 cm/s vs. 1943 ± 508 cm/s, P = 0.036) and IAND≥10 mmHg (1850 ± 476 cm/s vs. 1955 ± 509 cm/s, P = 0.000). Compared to others, those with IAD or IAND≥10 mmHg had higher systolic blood pressure (SBP), higher prevalence of hypertension, larger male gender ratio, bigger body mass index, higher pulse rate and lower ABI (P < 0.001 for all). A significant association with baPWV was observed for IAND≥10 mmHg (OR = 1.117; 95%CI: 1.039–1.201; P = 0.003) not for IAD≥10 mmHg (OR = 0.771; 95%CI: 0.699–0.851; P = 0.000) in multivariate logistic regression analysis. Conclusions Limb blood pressure differences were closely related to arterial stiffness and systolic blood pressure, allowing for a more comprehensive assessment of cardiovascular risk.
Suicide Among American Indian and Alaska Native Veterans Who Use Veterans Health Administration Care

Background: American Indian and Alaska Natives (AI/ANs) veterans may be at elevated risk for suicide, but little is known about suicide among this population. Methods: We conducted a retrospective cohort analysis of AI/AN veterans who received health care services provided or paid for by the Veterans Health Administration (VHA) between October 1, 2002, and September 30, 2014, and who were alive as of September 30, 2003. Age-specific and age-adjusted suicide rates through 2018, per 100,000 person-years (PY) at risk and 95% confidence intervals were computed. Results: Age-adjusted suicide rates among AI/AN veterans in this cohort more than doubled (19.1–47.0/100,000 PY) over the 15-year observation period. In the most recent observation period (2014–2018), the age-adjusted suicide rate was 47.0 per 100,000 PY, with the youngest age group (18–39) exhibiting the highest suicide rate (66.0/100,000 PY). The most frequently used lethal means was firearms (58.8%), followed by suffocation (19.3%), poisoning (17.2%), and other (4.7%). Conclusions: Results suggest that: (1) suicide is an increasing problem among AI/AN VHA veterans; and (2) younger AI/AN VHA veterans are at particularly high risk and warrant focused prevention efforts. Findings are similar to those observed in general AI/AN population. There is a compelling need to review and strengthen VHA suicide prevention efforts directed towards AI/AN veterans.
Patients’ Plasma Activity of Heparin, low-Molecular-Weight Heparin or no Anticoagulants on Urine Based DOAC Test Strips

DOAC Dipstick determines specifically the presence and absence of direct oral anticoagulants (DOACs) from patients’ urine samples and handmade test strips performed as well as the commercial version. To compare plasma activity (chromogenic substrate assays) from plasma samples with results from urine samples (DOAC test strips) of patients treated with heparin, low-molecular weight heparin (LMWH) and without anticoagulation. Plasma anti-factor Xa (aXa) activity was determined by Coamatic chromogenic substrate assay and compared to the presence of anticoagulants in urine by DOAC test strips. Patients were treated for least 5 days and samples were taken 4 hrs after administration in comparison to no treatment with an anticoagulant (n = 42). A total of 100 patients were included treated with heparin (n = 29), LMWH nadroparin (n = 29) or no anticoagulants (n = 42). Plasma aXa levels of patients treated with heparin (2 × 7.500 IU daily subcutaneously, 12 male, age 67.4 ± 11.5 years) were 0,18 IU/ml ± 0,15 IU/ml (mean, standard deviation), with LMWH (1 × 3000 IU daily subcutaneously, 15 male, age 64.2 ± 14.1 years) 0,17 IU/ml ± 0,16 IU/l, and with no anticoagulants (28 male, age 64.2 ± 15.6 years) 0,02 IU/ml ± 0.01 IU/ml. All factor Xa and thrombin inhibitor pad results of test strips were negative. We conclude that DOAC Dipstick has a high probability of not detecting heparin and LMWH in patients on treatment as well as in urine samples of patients not treated with an anticoagulant.
EVO+ Implantable Collamer Lens KS-aquaPORT Location, Stability, and Impact on Quality of Vision and Life.

PURPOSE To determine the longitudinal variation in the KS-aquaPORT central hole location of the phakic EVO+I Implantable Collamer Lens (ICL) (STAAR Surgical) and analyze its influence on visual performance, quality of vision (QoV), and quality of life (QoL). METHODS A prospective study was performed including 36 patients who had EVO+ ICL implantation. The KS-aquaPORT central hole location (Cartesian and polar coordinates) was determined with respect to the pupil center and visual axis. The effect of time (6-month follow-up) on central hole location was analyzed using linear mixed models. The effect of the KS-aquaPORT location on visual performance, QoV, and QoL parameters was assessed with multivariate regression models. RESULTS With respect to the visual axis, no significant changes in KS-aquaPORT location were found during follow-up. With respect to the pupil center, the X-coordinate and radius of KS-aquaPORT location showed modest, but significant (P ≤ .05) differences between 1-week and 3-month postoperative visits, and between 1-week and 6-month visits. X-coordinate variation was significant (P = .022) between 1-and 6-month visits. With respect to the visual axis, greater KS-aquaPORT decentration was associated with worse visual acuity (X-coordinate: P = .004; radius: P = .006), and inferior decentration with longer xenon-type glare photostress recovery time (P = .021). With respect to the pupil center, a lower radius was associated with better QoV scores (P ≤ .01) and temporal decentration produced higher ring-shaped dysphotopsia (P = .007). CONCLUSIONS EVO+ ICL KS-aquaPORT location appears to be clinically stable up to 6 months postoperatively. A central location of the EVO+ ICL KS-aquaPORT hole is preferred because it allows reduced perception of dysphotopic phenomena that can result in better QoV. [J Refract Surg. 2022;38(3):177-183. ].
Changes in peripheral blood T lymphocyte subsets predict disease progression in patients with rheumatoid arthritis.

OBJECTIVE To explore the correlation between abnormal changes in peripheral blood T lymphocyte subsets and disease progression in patients with active rheumatoid arthritis (RA). METHODS This is a retrospective study, in which 53 patients with active RA were selected as the study subjects and 50 healthy people were selected as the control group. Lymphocyte subsets were determined in both arms. According to whether CD4/CD8 ratio increased, RA patients were subdivided into an elevated CD4/CD8 group and a non-elevated CD4/CD8 group, and compared to the control group. The risk factors affecting the disease progression of patients with active RA were analyzed. RESULTS CD4+ T lymphocyte subsets in patients with increased CD4/CD8 were significantly higher than those in healthy controls. In addition, the elevated CD4/CD8 group showed significantly CD8+ T lymphocyte subsets than the non-elevated CD4/CD8 group and the control group (P<0.05). The CD4+ T lymphocyte subsets in the elevated CD4/CD8 group were not significantly higher than those in the non-elevated CD4/CD8 group (P>0.05). The CD3+ T lymphocyte subsets as well as CD19+ B and NK lymphocyte subsets showed no significant difference among the three arms (P>0.05). In addition, CD4, CD8 and CD4/CD8 were identified to be the risk factors affecting disease progression in patients with active RA. CONCLUSIONS When an autoimmune disorder occurs in patients with active RA, CD8+ T lymphocyte subsets are significantly suppressed, while CD4+ T lymphocyte subsets show different manifestations, with some patients presenting no obvious increase. In addition, CD4, CD8 and CD4/CD8 can help to indicate the risk of disease progression in patients with active RA.
