Differentiated nomological networks of internalizing, externalizing, and the general factor of psychopathology (‘p factor’) in emerging adolescence in the ABCD study

Abstract Background Structural models of psychopathology consistently identify internalizing (INT) and externalizing (EXT) specific factors as well as a superordinate factor that captures their shared variance, the p factor. Questions remain, however, about the meaning of these data-driven dimensions and the interpretability and distinguishability of the larger nomological networks in which they are embedded. Methods The sample consisted of 10 645 youth aged 9–10 years participating in the multisite Adolescent Brain and Cognitive Development (ABCD) Study. p, INT, and EXT were modeled using the parent-rated Child Behavior Checklist (CBCL). Patterns of associations were examined with variables drawn from diverse domains including demographics, psychopathology, temperament, family history of substance use and psychopathology, school and family environment, and cognitive ability, using instruments based on youth-, parent-, and teacher-report, and behavioral task performance. Results p exhibited a broad pattern of statistically significant associations with risk variables across all domains assessed, including temperament, neurocognition, and social adversity. The specific factors exhibited more domain-specific patterns of associations, with INT exhibiting greater fear/distress and EXT exhibiting greater impulsivity. Conclusions In this largest study of hierarchical models of psychopathology to date, we found that p, INT, and EXT exhibit well-differentiated nomological networks that are interpretable in terms of neurocognition, impulsivity, fear/distress, and social adversity. These networks were, in contrast, obscured when relying on the a priori Internalizing and Externalizing dimensions of the CBCL scales. Our findings add to the evidence for the validity of p, INT, and EXT as theoretically and empirically meaningful broad psychopathology liabilities.
Noninvasive screening for congenital heart defects using a serum metabolomics approach

Heart anomalies represent nearly one‐third of all congenital anomalies. They are currently diagnosed using ultrasound. However, there is a strong need for a more accurate and less operator‐dependent screening method. Here we report a metabolomics characterization of maternal serum in order to describe a metabolomic fingerprint representative of heart congenital anomalies.
Nuclear Receptors and Development of Marine Invertebrates

Nuclear Receptors (NRs) are a superfamily of transcription factors specific to metazoans that have the unique ability to directly translate the message of a signaling molecule into a transcriptional response. In vertebrates, NRs are pivotal players in countless processes of both embryonic and adult physiology, with embryonic development being one of the most dynamic periods of NR activity. Accumulating evidence suggests that NR signaling is also a major regulator of development in marine invertebrates, although ligands and transactivation dynamics are not necessarily conserved with respect to vertebrates. The explosion of genome sequencing projects and the interpretation of the resulting data in a phylogenetic context allowed significant progress toward an understanding of NR superfamily evolution, both in terms of molecular activities and developmental functions. In this context, marine invertebrates have been crucial for characterizing the ancestral states of NR-ligand interactions, further strengthening the importance of these organisms in the field of evolutionary developmental biology.
Coexistence of Communicating and Noncommunicating Cells in the Filamentous Cyanobacterium Anabaena

Multicellularity is found in bacteria as well as in eukaryotes, and the filamentous heterocyst-forming (N2-fixing) cyanobacteria represent a simple and ancient paradigm of multicellular organisms. Multicellularity generally involves cell-cell adhesion and communication. ABSTRACT In filamentous heterocyst-forming (N2-fixing) cyanobacteria, septal junctions join adjacent cells, mediating intercellular communication, and are thought to traverse the septal peptidoglycan through nanopores. Fluorescence recovery after photobleaching (FRAP) analysis with the fluorescent marker calcein showed that cultures of Anabaena sp. strain PCC 7120 grown in the presence of combined nitrogen contained a substantial fraction of noncommunicating cells (58% and 80% of the tested vegetative cells in nitrate- and ammonium-grown cultures, respectively), whereas cultures induced for nitrogen fixation contained far fewer noncommunicating cells (16%). A single filament could have communicating and noncommunicating cells. These observations indicate that all (or most of) the septal junctions in a cell can be coordinately regulated and are coherent with the need for intercellular communication, especially under diazotrophic conditions. Consistently, intercellular exchange was observed to increase in response to N deprivation and to decrease rapidly in response to the presence of ammonium in the medium or to nitrate assimilation. Proteins involved in the formation of septal junctions have been identified in Anabaena and include SepJ, FraC, and FraD. Here, we reevaluated rates of intercellular transfer of calcein and the number of nanopores in mutants lacking these proteins and found a strong positive correlation between the two parameters only in cultures induced for nitrogen fixation. Thus, whereas the presence of a substantial number of noncommunicating cells appears to impair the correlation, data obtained in diazotrophic cultures support the idea that the nanopores are the structures that hold the septal junctions. IMPORTANCE Multicellularity is found in bacteria as well as in eukaryotes, and the filamentous heterocyst-forming (N2-fixing) cyanobacteria represent a simple and ancient paradigm of multicellular organisms. Multicellularity generally involves cell-cell adhesion and communication. The cells in the cyanobacterial filaments are joined by proteinaceous septal junctions that mediate molecular diffusion. The septal junctions traverse the septal peptidoglycan, which bears holes termed nanopores. Our results show that the septal junctions can be coordinately regulated in a cell and emphasize the relationship between septal junctions and nanopores to build intercellular communication structures, which are essential for the multicellular behavior of heterocyst-forming cyanobacteria.
Patients with Minimal Hepatic Encephalopathy Show Altered Thermal Sensitivity and Autonomic Function

Cirrhotic patients may experience alterations in the peripheral nervous system and in somatosensory perception. Impairment of the somatosensory system could contribute to cognitive and motor alterations characteristic of minimal hepatic encephalopathy (MHE), which affects up to 40% of cirrhotic patients. We assessed the relationship between MHE and alterations in thermal, vibration, and/or heat pain sensitivity in 58 cirrhotic patients (38 without and 20 with MHE according to Psychometric Hepatic Encephalopathy Score) and 39 controls. All participants underwent attention and coordination tests, a nerve conduction study, autonomic function testing, and evaluation of sensory thresholds (vibration, cooling, and heat pain detection) by electromyography and quantitative sensory testing. The detection thresholds for cold and heat pain on the foot were higher in patients with, than those without MHE. This hyposensitivity was correlated with attention deficits. Reaction times in the foot were longer in patients with, than without MHE. Patients with normal sural nerve amplitude showed altered thermal sensitivity and autonomic function, with stronger alterations in patients with, than in those without MHE. MHE patients show a general decrease in cognitive and sensory abilities. Small fibers of the autonomic nervous system and thermal sensitivity are altered early on in MHE, before large sensory fibers. Quantitative sensory testing could be used as a marker of MHE.
Ultrasound Imaging and Guidance in Common Wrist/Hand Pathologies

Supplemental digital content is available in the text. Abstract Wrist/hand pain is a prevalent musculoskeletal condition with a great spectrum of etiologies (varying from overuse injuries to soft tissue tumors). Although most of the anatomical structures are quite superficial and easily evaluated during physical examination, for several reasons, the use of ultrasound imaging and guidance has gained an intriguing and paramount concern in the prompt management of relevant patients. In this aspect, the present review aims to illustrate detailed cadaveric wrist/hand anatomy to shed light into better understanding the corresponding ultrasonographic examinations/interventions in carpal tunnel syndrome, trigger finger, de Quervain tenosynovitis, rhizarthrosis, and the radiocarpal joint arthritis. In addition, evidence from the literature supporting the rationale why ultrasound guidance is henceforth unconditional in musculoskeletal practice is also exemplified.
Morphology and Particle Size Distribution Controls of Droplet-to-Macroporous/Hollow Particles Formation in Spray Drying Process of Colloidal Mixtures Precursor

The morphology control of droplet-to-macroporous/hollow particles formation using an ultrasonically spray-drying method as well as correlation between the droplet and particle size distribution of generated particles using a precursor of colloidal mixtures of polystyrene latex (PSL) and negatively charged silica nanoparticles were demonstrated. Porous particles were successfully produced by negatively charged PSL colloids. On the other hand, positively charged PSL colloids tended to generate hollow particles. The measured particle size distribution (PSD) of hollow particles agreed well with the calculated PSD using a mass balance principle of droplet to drying particles of silica and PSL composites. However, for porous particle formation, the measured PSD was smaller than the calculated PSD. The effects of PSL and silica colloids concentrations on a starting material as well as process residence time on the final porous particles were also investigated. A high PSL colloid concentration, low silica colloid concentration, and a short residence time of the process led to higher PSD deviation between the measurement and the calculation. The cause of these phenomena was also discussed in this article.
Techniques to select site of insertion for a peripheral intravenous catheter with vessel locating devices using light, sounds or tactile actions (or palpations).

BACKGROUND Approximately 80% of patients admitted to acute hospitals have at least one peripheral intravenous catheter inserted during their admission, for the administration of fluids and medicines, and/or diagnostic tests, so the failure rate is concerning. New technology may decrease these rates even when used by inexperienced inserters. The choice of insertion site for an intravenous catheter is a known predictor of catheter failure. Therefore, the objective for this study was to evaluate the utility of vessel locating devices for novice clinicians to select catheter insertion sites in the forearm. METHODS An inter-subject incomplete counterbalanced research design was employed with healthy volunteers. Novice clinicians used either a vessel locating device using light or sound waves or they used palpation to identify relatively superficial veins in the forearm. This was compared to site selection performed by an expert clinician using palpation method only. Measurements of differences were analysed from photos of chosen sites. Bland-Altman agreement analysis was used to plot novice expert agreement. The STROBE checklist was followed in reporting this study (Techniques to select site of insertion for a peripheral intravenous catheter with vessel locating devices (Supplementary File 1)). RESULTS A total of 32 novice clinicians used three vessel locating devices and a palpation technique. Novice clinicians did not choose more veins for optimum catheter placement when assisted with vessel locating devices compared to palpation techniques. All methods had a similar mean difference between novice and expert measurements and a similar percentage difference in distance from the expert choice. Bland-Altman agreement analysis did not identify any advantage for the novice with vessel locating devices over palpation. CONCLUSION Vessel locating devices do not enhance the ability of novice clinicians any greater than palpation when selecting suitable forearm veins. If vessel locating device approaches are to be adopted in clinical practice to support better insertion outcomes then current PIVC teaching techniques should include structured vessel locating devices theory and practice.

E17241 as a Novel ABCA1 (ATP-Binding Cassette Transporter A1) Upregulator Ameliorates Atherosclerosis in Mice

Supplemental Digital Content is available in the text. Objective: Reverse cholesterol transport, removing excess cholesterol from peripheral tissues, is an important therapeutic target for atherosclerosis treatment. In this study, we propose a new small molecule, E17241, that may be used to treat atherosclerosis by promoting reverse cholesterol transport via ABCA1 (ATP-binding cassette transporter A1) upregulation. Approach and Results: E17241 (4-(1,3-dithiolan-2-yl)-N-(3-hydroxypyridin-2-yl)benzamide) was first identified as an ABCA1 upregulator using a cell-based reporter assay. E17241 significantly increases the mRNA and protein expression levels of ABCA1 in both hepatic cells and macrophages. It promotes cholesterol efflux to apo AI in macrophage cells, and this effect depends on ABCA1. It also decreases total cholesterol content in Ox-LDL (oxidized low-density lipoprotein) loading macrophage cells. E17241 treatment increases the content of 3H-labeled cholesterol in the feces of male C57BL/6J mice intraperitoneally injected with 3H-cholesterol-labeled macrophage J774 cells, indicating that it could promote in vivo macrophage reverse cholesterol transport. Compared with the western diet group (western diet–fed male ApoE−/− mice), the E17241 group (western diet+E17241 treatment) shows decreased plasma cholesterol, liver cholesterol, and triglyceride levels, with increased fecal cholesterol content. Importantly, E17241 reduces atherosclerotic lesion areas in the en face aorta and aortic sinus while increasing ABCA1 protein levels in both liver and macrophages. Human proteome microarray, coimmunoprecipitation, and other assays demonstrate that PKCζ (protein kinase C zeta) is a binding target of E17241, and this small molecule increases ABCA1 expression in macrophages via the PKCζ-NR (nuclear receptor) pathway. Conclusions: E17241 may be developed as a new lead or drug candidate for the treatment of atherosclerosis by upregulating ABCA1.
Expression and Possible Role of Nicotinic Acetylcholine Receptor ε Subunit (AChRe) in Mouse Sperm

Simple Summary Numerous neurotransmitters have been reported to affect mammalian sperm function and are thought to play an important role in the phenomenon of fertilization. This study focused on acetylcholine (ACh) and its receptor subunit, the ε subunit (AChRe), and analyzed the effect of ACh and AChRe on mammalian sperm function and fertilization. The present study revealed the localization of AChRe in the murine testes and spermatozoa, and showed that acrosome reaction (AR), an important change in sperm function associated with fertilization, is suppressed by ACh. Furthermore, this suppressing effect was significantly inhibited by an AChRe specific antagonist, suggesting that AChRe play as a regulator of mammalian sperm AR. These results may aid in further elucidating the phenomenon of mammalian sperm function for fertilization by ACh and in the establishment of a new method of superior sperm selection via AChRe. Abstract The nicotinic acetylcholine receptor (nAChR) is one of the receptors of acetylcholine (ACh), and nicotine (NIC) acts as an agonist of this receptor. Among the nAChR subunits, we found that the ε subunit (AChRe) had approximately 10 to 1000 times higher level of mRNA expression in mouse testes than the other subunits. In this study, we aimed to elucidate the expression and localization of AChRe in the testes and spermatozoa of mice and clarify the effect of AChRe on sperm function. Immunocytochemistry showed that AChRe was expressed in the murine testes and spermatozoa. We found that AChRe was localized only in elongated spermatids from step 12 onwards in the testes. In spermatozoa, AChRe was localized in the head, especially in the anterior region of the acrosome, but only approximately 50% of spermatozoa showed this immunoreactivity. Additionally, we analyzed the effects of ACh and NIC on sperm acrosome reaction (AR) and found that both ACh and NIC suppressed the AR rate, which was restored by an AChRe-specific antagonist. These results suggest that AChRe may be a regulator of mammalian sperm AR.
Neurokinin-1 receptor (NK-1R) antagonists: potential targets in the treatment of glioblastoma multiforme.

The current standard of care in glioblastoma multiforme (GBM), as the most morbid brain tumor, is not adequate, despite substantial progress in cancer therapy. Among patients receiving current standard treatments, including surgery, irradiation, and chemotherapy, the overall survival (OS) period with GBM is less than one year. The high mortality frequency of GBM is due to its aggressive nature, including accelerated growth, deregulated apoptosis, and invasion into surrounding tissues. The understanding of the molecular pathogenesis of GBM is, therefore, crucial for identifying, designing, and repurposing potential agents in future therapeutic approaches. In recent decades, it has been apparent that several neurotransmitters, specifically substance P (SP), an undecapeptide in the family of neuropeptides tachykinins, are found in astrocytes. After binding to the neurokinin-1 receptor (NK-1R), the SP controls cancer cell growth, exerts antiapoptotic impacts, stimulates cell invasion/metastasis, and activates vascularization. Since SP/NK-1R signaling pathway is a growth driver in many cancers, this potential mechanism is proposed as an additional target for treating GBM. Following an evaluation of the function of both SP and its NK-1R inhibitors in neoplastic cells, we recommend a unique and promising approach for the treatment of patients with GBM.
Efficacy and safety of domestic and imported gefitinib in patients with advanced non-small cell lung cancer.

BACKGROUND Gefitinib is a first-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI). It was approved by the U.S. Food and Drug Administration (FDA) for clinical use in 2003. However, gefitinib has only come to China in recent years. Previous studies have not compared the efficacy and safety of domestic and imported gefitinib. Therefore, we conducted this study. METHODS This study included 227 patients with advanced non-small cell lung cancer (NSCLC) who received gefitinib treatment in four medical institutions: The First Affiliated Hospital of USTC, Division of life Sciences and Medicine, University of Science and Technology of China, Anhui Provincial Cancer Hospital, Fudan University Shanghai Cancer Center, Shandong Provincial Institute of Cancer Prevention and Jiangsu Cancer Hospital, from January 2017 to July 2018. The patients were divided into a Yiruike group (55 patients treated with domestic gefitinib, Yiruike) and an Iressa group (172 patients treated with imported gefitinib, Iressa). Because gefitinib resistance usually occurs within 8-10 months of gefitinib administration, the patients were followed up for one year to observe their conditions and compare the occurrence of adverse reactions between the two groups. RESULTS The two groups had no significant difference in baseline data. The median progression-free survival (PFS) of Yiruike group and that of Iressa group were 10.270±2.036 and 12.970±1.634 months, respectively. The mean PFS of Yiruike group and that of Iressa group were 12.598±1.083 and 15.958±0.987 months, respectively. The one-year disease control rate (DCR) of Yiruike group and that of Iressa group were 61.8% and 59.3%, respectively. The differences were all insignificant (P>0.05). The incidence of adverse reactions in these two groups were not significantly different. CONCLUSIONS Yiruike was slightly superior to Iressa in terms of DCR. However, comparisons of bioequivalence and DCR were not sufficient for evaluating a drug. Other comparisons require long-term follow-up studies with a large sample size.
Utility of radial endobronchial ultrasonography combined with transbronchial lung cryobiopsy in patients with diffuse parenchymal lung diseases: a multicentre prospective study

Background Radial endobronchial ultrasonography (R-EBUS) has been used in conjunction with transbronchial lung cryobiopsy (TBLC) to diagnose diffuse parenchymal lung disease (DPLD) and to decrease the risk of bleeding complications. The diagnostic utility of different R-EBUS signs, however, remains unknown. Objectives This study aimed to determine whether different R-EBUS signs could be used to more accurately diagnose DPLD and whether bronchial bleeding could be prevented with use of R-EBUS during TBLC. Method Eighty-seven patients with DPLD were included in this multicentre prospective study, with 49 patients undergoing R-EBUS. R-EBUS signals were characterised as displaying either dense or blizzard signs. Pathological confidence of specimens obtained from TBLC was compared between patients with dense versus blizzard signs, and severity of bronchial bleeding was determined based on whether R-EBUS was performed or not. Results All patients with dense signs on R-EBUS showed consolidation on high-resolution CT (HRCT) imaging. Pathological confidence of lung specimens was significantly higher in patients with dense signs versus those with blizzard signs (p<0.01) and versus those who did not undergo R-EBUS (p<0.05). Patients who underwent TBLC with R-EBUS were more likely to experience no or mild bronchial bleeding than patients who did not undergo R-EBUS (p<0.01), with shorter procedure times (p<0.01). Conclusions The dense R-EBUS sign corresponded with consolidation on HRCT. High-quality lung specimens may be obtainable when the dense sign is observed on R-EBUS, and R-EBUS combined with TBLC may reduce risk of bronchial bleeding and shorten procedure times.
