Kidney Single-Cell Atlas Reveals Myeloid Heterogeneity in Progression and Regression of Kidney Disease.

Background: Little is known about the roles of myeloid cell subsets in kidney injury and in the limited ability of the organ to repair itself. Characterizing these cells based only on surface markers using flow cytometry might not provide a full phenotypic picture. Defining these cells at the single-cell, transcriptomic level could reveal myeloid heterogeneity in the progression and regression of kidney disease.

Discovery of novel liver X receptor inverse agonists as lipogenesis inhibitors.

Based on the co-crystal structures of LXRβ and its agonists (spiro [pyrrolidine-3,3'-oxindole] derivatives) discovered by us previously, we designed and synthesized a compound library to explore the agonistic activities. The library was screened with luciferase reporter assays, interestingly, it resulted in the discovery of 10 LXR inverse agonists besides 5 LXR agonists. To clarify the mechanism of the actions, we conducted molecular dynamics (MD) simulations on the LXR and inverse agonists complexes, and revealed that H3, H11 and H12 configurations are the key to turn on agonism or inverse agonism status for LXR.

Circular RNA circ_0010283 regulates the viability and migration of oxidized low‑density lipoprotein‑induced vascular smooth muscle cells via an miR‑370‑3p/HMGB1 axis in atherosclerosis.

Atherosclerosis is a disease during which the inside of an artery narrows due to the accumulation of plaque, and vascular smooth muscle cells (VSMCs) are involved in the progression of atherosclerosis. Circular RNAs (circRNAs) have been reported to be involved in the progression of atherosclerosis. However, the role of circ_0010283 in atherosclerosis progression remains unclear.

Analysis and identification of novel biomarkers involved in neuroblastoma via integrated bioinformatics.

Neuroblastoma (NB) is the most common extracranial solid tumor in children. Under various treatments, some patients still have a poor prognosis. Hence, it is necessary to find new valid targets for NB therapy.

Effects of the brown algae Sargassum horneri and Saccharina japonica on survival, growth and resistance of small sea urchins Strongylocentrotus intermedius.

Mass mortality of the long line culture of the sea urchin Strongylocentrotus intermedius in summer, which is greatly associated with their disease, energy storage and resistant abilities, is the most serious problem for the development of the aquaculture. Here, a feeding experiment was conducted for ~ 9 weeks to investigate the survival, growth and gonadal development of small S. intermedius (~ 3 cm) fed either brown algae Sargassum horneri or Saccharina japonica.

Domain- and trimester-specific effect of prenatal phthalate exposure on preschooler cognitive development in the Ma'anshan Birth Cohort (MABC) study.

Background: Phthalates are a group of heavily produced endocrine disruptors that are widely used in personal care products, food packaging, building materials, and medical device. Few epidemiological studies have examined the effect of repeated prenatal exposure to multiple phthalates on preschooler cognitive development.

Objectives: This study aimed to examine the association between prenatal phthalate exposure measured at multiple time points and the intelligent quotient (IQ) scores of preschoolers, and to further identify the critical windows and specific intelligence domains in which phthalate exposure would affect preschooler cognitive development.

Evaluation of clinical efficacy of integrated traditional Chinese and Western medicine in the treatment of acute respiratory distress syndrome.

Introduction: Acute respiratory distress syndrome (ARDS) is a common disease in critically ill patients that has a high incidence and mortality rate worldwide. At present, there is no specific treatment for ARDS. Traditional Chinese medicine has been shown to have good potential in preventing and treating ARDS, especially in reducing the dosages of Western medicines and therefore, adverse drug reactions.

Association Between Screen Time, Fast Foods, Sugar-Sweetened Beverages and Depressive Symptoms in Chinese Adolescents.

Objective: Although previous studies have shown that screen time (ST), fast foods (FFs) and sugar-sweetened beverages (SSBs) consumption are associated with depressive symptoms in adolescents, research on these associations in Chinese adolescents is scarce. This study aimed to examine the association between ST, FFs, SSBs and depressive symptoms in Chinese adolescents, and explore the mediating effects of FFs and SSBs in the association between ST and depressive symptoms.

Methods: This school-based nationwide survey was carried out among 14,500 students in four provinces of China.

Europium based coordination polyelectrolytes enable core-shell-corona micelles as luminescent probes.

Core-shell-corona (CSC) micelles have multiple layers, which can serve as separate compartments. This property allows them to combine multiple functionalities in a single nanoparticle, with obvious application potential. Here, we propose a new type of CSC micelles with an apolar core and a polyelectrolyte complex shell incorporating coordination polymers.

Melatonin ameliorates pressure overload-induced cardiac hypertrophy by attenuating Atg5-dependent autophagy and activating the Akt/mTOR pathway.

Cardiac hypertrophy, including hypertension and valvular dysfunction, is a pathological feature of many cardiac diseases that ultimately leads to heart failure. Melatonin confers a protective role against pathological cardiac hypertrophy, but the underlying mechanisms remain elusive. In the present study, we hypothesized that melatonin protects against pressure overload-induced cardiac hypertrophy by attenuating Atg5-dependent autophagy and activating the Akt/mTOR pathway.

Discovery of new LXRβ agonists as glioblastoma inhibitors.

Discovery and optimization of selective liver X receptor β (LXRβ) agonists are challenging due to the high homology of LXRα and LXRβ in the ligand-binding domain. There is only one different residue (Val versus Ile) at the ligand-binding pocket of LXRs. With machine learning methods, we identified pan LXR agonists with a novel scaffold (spiro[pyrrolidine-3,3'-oxindole]).

Demodulation of a weak fiber Bragg grating array using a fiber delay line.

We demonstrate the use of a fiber delay line (FDL) to demodulate a weak fiber Bragg grating (WFBG) array. The FDL is composed of a fiber-ring cavity, by which the delay time is matched with the interval length of the adjacent WFBGs. Two pulses reflected by the former WFBG with delay and a pulse reflected by the rear WFBG without delay overlap and interfere.

Effects of Superior Laryngeal Nerve Lesion on Kinematics of Swallowing and Airway Protection in an Infant Pig Model.

The superior laryngeal nerve provides detailed sensory information from the mucosal surfaces of laryngeal structures superior to the vocal folds, including the valleculae. Injury to this nerve results in airway penetration and aspiration. Furthermore, such injuries might have an impact on the function of multiple structures involved in intraoral transport and swallowing due to connections within the brainstem.

Sugar-sweetened beverages consumption are associated with behavioral problems among preschoolers: A population based cross-sectional study in China.

Background: Previous researches showed a positive association between sugar-sweetened beverages (SSB) and behavioral problems, but there is a little known in Chinese preschoolers.

Methods: A population based survey was conducted in 109 kindergartens, in 11 cities across China. Children's SSB consumption was assessed by questionnaires completed by caregivers.

Urothelial Carcinoma Detection Based on Copy Number Profiles of Urinary Cell-Free DNA by Shallow Whole-Genome Sequencing.

Background: Current noninvasive assays for urothelial carcinoma (UC) lack clinical sensitivity and specificity. Given the utility of plasma cell-free DNA (cfDNA) biomarkers, the development of urinary cfDNA biomarkers may improve the diagnostic sensitivity.

Methods: We assessed copy number alterations (CNAs) by shallow genome-wide sequencing of urinary cfDNA in 95 cancer-free individuals and 65 patients with UC, 58 with kidney cancer, and 45 with prostate cancer.

Sharp bounds on the relative treatment effect for ordinal outcomes.

For ordinal outcomes, the average treatment effect is often ill-defined and hard to interpret. Echoing Agresti and Kateri, we argue that the relative treatment effect can be a useful measure, especially for ordinal outcomes, which is defined as , with and being the potential outcomes of unit under treatment and control, respectively. Given the marginal distributions of the potential outcomes, we derive the sharp bounds on which are identifiable parameters based on the observed data.

Overexpression of Tripartite Motif-Containing 48 (TRIM48) Inhibits Growth of Human Glioblastoma Cells by Suppressing Extracellular Signal Regulated Kinase 1/2 (ERK1/2) Pathway.

BACKGROUND Herein, we found that tripartite motif-containing 48 (TRIM48) was reduced in human glioblastoma (GBM) cell lines. We investigated whether and how TRIM48 functions in human GBM in vitro. MATERIAL AND METHODS Human GBM cells (U87 MG and U138 MG) were infected with lentivirus to overexpress TRIM48, and 1 human GBM cell line (T98G) was infected with siRNAs to knock down TRIM48 expression.

RstA, a two-component response regulator, plays important roles in multiple virulence-associated processes in enterohemorrhagic O157:H7.

Background: Enterohemorrhagic O157:H7 (EHEC O157) causes bloody diarrhea and hemolytic-uremic syndrome. EHEC O157 encounters varied microenvironments during infection, and can efficiently adapt to these using the two-component system (TCS). Recently, a functional TCS, RstAB, has been implicated in the regulation of virulence of several bacterial pathogens.

Transcriptional Activator OvrA Encoded in O Island 19 Modulates Virulence Gene Expression in Enterohemorrhagic Escherichia coli O157:H7.

The human intestinal pathogen enterohemorrhagic Escherichia coli (EHEC) O157:H7 causes bloody diarrhea, hemorrhagic colitis, and fatal hemolytic uremic syndrome. Its genome contains 177 unique O islands (OIs), which contribute largely to the high virulence and pathogenicity although most OI genes remain uncharacterized. In the current study, we demonstrated that OI-19 is required for EHEC O157:H7 adherence to host cells.

Refocusable Gigapixel Panoramas for Immersive VR Experiences.

There have been significant advances in capturing gigapixel panoramas (GPP). However, solutions for viewing GPPs on head-mounted displays (HMDs) are lagging: an immersive experience requires ultra-fast rendering while directly loading a GPP onto the GPU is infeasible due to limited texture memory capacity. In this paper, we present a novel out-of-core rendering technique that supports not only classic panning, tilting, and zooming but also dynamic refocusing for viewing a GPP on HMD.

Risk evaluation of splenic hilar or splenic artery lymph node metastasis and survival analysis for patients with proximal gastric cancer after curative gastrectomy: a retrospective study.

Background: As splenectomy and spleen-preserving lymphadenectomy are performed only in some proximal gastric cancer patients, it is difficult to identify patients who have undergone radical gastrectomy with or without splenic hilar (No.10) or splenic artery (No.11) lymph node metastases.
