RESUMEN

In 2014, guns were the second leading cause of death among children and teens in the U.S. and it was previously found that approximately 33% of children live in homes with a firearm (Schuster et al., 2000). Currently, the AAP recommends pediatricians address firearms and firearm safety with patients; however, available research regarding the methods pediatricians use to communicate with patients regarding firearms and the influences on decision making is mixed and in need of more studies. Utilizing concepts from the theory of planned behavior and the health belief model, this paper presents findings from an online survey of medical doctors in several pediatric residency programs and seeks to identify the influences on prioritization of firearm safety in one's anticipatory guidance. Findings indicate that many residents do not counsel on firearm safety during well child visits. Further, prioritization is influenced by comfort, training, and confidence. Gender differences were also found, wherein women are more likely to indicate that firearm safety is as important as other anticipatory guidance messages, but also indicate less confidence in abilities to counsel. Theoretical and practical implications, including possibilities for future research and interventions, are discussed.

RESUMEN

To investigate the protective function of low-level laser irradiation (LLLI) against ionizing irradiation and explore the molecular mechanism of photomodulation of Nrf2 protein, the impact of LLLI (635 nm, 5.7 J/cm2) before 2 Gy gamma ray radiation of radio-sensitive tissue hematopoietic stem cells was evaluated. As a result, reduced levels of reactive oxygen species and increased expression of antioxidant enzymes were detected. Moreover, increased expression of Nrf2 was observed after LLLI, whereas brusatol pretreatment before LLLI abolished this effect. In vivo, transplantation of human umbilical cord mesenchymal stem cells (hUC-MSCs) was employed for therapy of hematopoietic function in an acute radiation sickness (H-ARS) mouse model, which was induced by 6-Gy ionizing irradiation; different hUC-MSC pretreatments including LLLI and Nrf2 RNAi were accounted for during experimental grouping. LLLI treatment of cells significantly increased the erythrocyte count and number of myelopoiesis clones (P < 0.05), but such improvements were reduced by Nrf2 RNAi pretreatment compared with cells transplanted without intervention. Therefore, LLLI may improve the radiation protection effect through molecular mechanisms related to the Nrf2 antioxidant pathway.

RESUMEN

Flatfoot is linked to secondary lower limb joint problems, such as patellofemoral pain. This study aimed to investigate the influence of medial posting insoles on the joint mechanics of the lower extremity in adults with flatfoot. Gait analysis was performed on fifteen young adults with flatfoot under two conditions: walking with shoes and foot orthoses (WSFO), and walking with shoes (WS) in random order. The data collected by a vicon system were used to drive the musculoskeletal model to estimate the hip, patellofemoral, ankle, medial and lateral tibiofemoral joint contact forces. The joint contact forces in WSFO and WS conditions were compared. Compared to the WS group, the second peak patellofemoral contact force (p < 0.05) and the peak ankle contact force (p < 0.05) were significantly lower in the WSFO group by 10.2% and 6.8%, respectively. The foot orthosis significantly reduced the peak ankle eversion angle (p < 0.05) and ankle eversion moment (p < 0.05); however, the peak knee adduction moment increased (p < 0.05). The reduction in the patellofemoral joint force and ankle contact force could potentially inhibit flatfoot-induced lower limb joint problems, despite a greater knee adduction moment.

RESUMEN

As an important edible traditional Chinese medicine, Codonopsis pilosula has good immunomodulation effects. This study focuses on C. pilosula oligosaccharides (CPO), which are the sweetness components of C. pilosula. CPO were obtained through systematic separation and purification (the yield is 14.3%), and the effect of CPO on the immunological activities of immunocompromised mice induced by cyclophosphamide (CTX) was evaluated. The results showed that CPO could increase immune organ indices, phagocytic index and immunoglobulin contents, stimulate the proliferation of splenic lymphocytes (coordinating with ConA and LPS), enhance the earlap swelling of the DTH reaction, promote the production of NO and cytokines (IL-2 and IFN-γ) and upregulate the expression of the corresponding mRNA. In addition, CPO upregulated the protein expression of phosphorylated p38, phosphorylated ERK1/2 and phosphorylated JNK, which indicated that CPO might exert immunomodulatory effects through the MAPK signaling pathway. These findings indicated that CPO are important immunomodulatory components in C. pilosula and could be developed as immunomodulators in medicine or functional food areas.

RESUMEN

Despite numerous investigations into AgNP-induced toxicity, little has been taken into consideration the potential health impacts of aged AgNPs in comparison to fresh AgNPs. In the current study, we scrutinized the potential effects of aged AgNPs in animals. We first found that AgNPs underwent morphological transformations after natural ageing in aqueous solution upon exposure to air and sunlight for 9 days, as characterized by significant aggregation with increase of particle size approximately by 2 fold. Meanwhile, dissolved Ag ions from aged AgNPs increased by 33% compared to fresh AgNPs. Strikingly, the acute exposure results showed that aged AgNPs induced lower toxicity in mice relative to fresh AgNPs. Aged AgNPs caused milder local inflammation in the peritoneal cavity of mice, as evidenced by 63% reduction of tumor necrosis factor α (TNF-α) than that induced by fresh AgNPs. The deposition mass of aged AgNPs in the liver, spleen, lung and kidney was diminished by 69%, 39%, 83% and 40%, respectively, compared to the distribution profiles in response to fresh AgNPs. Whereby, milder splenic hyperemia was observed, and no significant hepatoxicity was found. Additionally, aged AgNPs provoked milder increase of periphery leukocytes and malondialdehyde (MDA) in mice in comparison to fresh AgNPs. Taken together, this study unraveled that the ageing process elicited remarkable alterations to physicochemical properties and toxic effects as well. This study would provide new insights into the potential health impacts of AgNPs under transformation-determined exposure scenarios.

RESUMEN

Endoscopic techniques have been applied to oral and maxillofacial surgeries. Previous studies have proved their practicability in the treatment of osteomyelitis of the mandible and displaced residual roots in the maxillary sinus. In this report, two patients with dentigerous cysts in the maxillary sinus underwent endoscope-assisted curettage. Both patients were successfully cured without recurrent lesions or any complications. The follow-up found that the bone cavities had shrunk. An endoscope-assisted Caldwell-Luc operation provided clear visibility of the surgical field and preserved the mucosa of the maxillary sinus.

RESUMEN

BACKGROUND: Metastasis-associated lung adenocarcinoma transcript-1 (MALAT1) was aberrantly expressed in diverse diseases. Particularly in ischemic stroke (IS), the abnormal expression of MALAT1 played important roles including promotion of angiogenesis, inhibition of apoptosis and inflammation and regulation of autophagy. However, the effects of genetic variation (single nucleotide polymorphisms, SNPs) of MALAT1 on IS have rarely been explored. This study aimed to investigate whether SNPs in promoter of MALAT1 were associated with the susceptibility to IS. METHODS: A total of 316 IS patients and 320 age-, gender-, and ethnicity-matched controls were enrolled in this study. Four polymorphisms in the promoter of MALAT1 (i.e., rs600231, rs1194338, rs4102217, and rs591291) were genotyped by using a custom-by-design 48-Plex SNPscan kit. RESULTS: The rs1194338 C > A variant in the promoter of MALAT1 was associated with the risk of IS (AC vs. CC: adjusted OR = 0.623, 95% CI, 0.417-0.932, P = 0.021; AA vs. CC: adjusted OR = 0.474, 95% CI, 0.226-0.991, P = 0.047; Dominant model: adjusted OR = 0.596, 95% CI, 0.406-0.874, P = 0.008; A vs. C adjusted OR = 0.658, 95% CI, 0.487-0.890, P = 0.007). The haplotype analysis showed that rs600231-rs1194338-rs4102217-rs591291 (A-C-G-C) had a 1.3-fold increased risk of IS (95% CI, 1.029-1.644, P = 0.027). Logistic regression analysis identified some independent impact factors for IS including rs1194338 AC/AA, TC, TG, HDL-C, LDL-C, Apo-A1, Apo-B and NEFA (P < 0.05). CONCLUSIONS: These results suggest that the rs1194338 AC/AA genotypes may be a protective factor for IS.

RESUMEN

Social hierarchies emerged during evolution, and social rank influences behavior and health of individuals. However, the evolutionary mechanisms of social hierarchy are still unknown in amniotes. Here we developed a new method and performed a genome-wide screening for identifying regions with accelerated evolution in the ancestral lineage of placental mammals, where mammalian social hierarchies might have initially evolved. Then functional analyses were conducted for the most accelerated region designated as placental-accelerated sequence 1 (PAS1, P = 3.15 × 10-18). Multiple pieces of evidence show that PAS1 is an enhancer of the transcription factor gene Lhx2 involved in brain development. PAS1s isolated from various amniotes showed different cis-regulatory activity in vitro, and affected the expression of Lhx2 differently in the nervous system of mouse embryos. PAS1 knock-out mice lack social stratification. PAS1 knock-in mouse models demonstrate that PAS1s determine the social dominance and subordinate of adult mice, and that social ranks could even be turned over by mutated PAS1. All homozygous mutant mice had normal huddled sleeping behavior, motor coordination and strength. Therefore, PAS1-Lhx2 modulates social hierarchies and is essential for establishing social stratification in amniotes, and positive Darwinian selection on PAS1 plays pivotal roles in the occurrence of mammalian social hierarchies.

RESUMEN

Prostate cancer is the second most common cancer in men worldwide1. Over the past decade, large-scale integrative genomics efforts have enhanced our understanding of this disease by characterizing its genetic and epigenetic landscape in thousands of patients2,3. However, most tumours profiled in these studies were obtained from patients from Western populations. Here we produced and analysed whole-genome, whole-transcriptome and DNA methylation data for 208 pairs of tumour tissue samples and matched healthy control tissue from Chinese patients with primary prostate cancer. Systematic comparison with published data from 2,554 prostate tumours revealed that the genomic alteration signatures in Chinese patients were markedly distinct from those of Western cohorts: specifically, 41% of tumours contained mutations in FOXA1 and 18% each had deletions in ZNF292 and CHD1. Alterations of the genome and epigenome were correlated and were predictive of disease phenotype and progression. Coding and noncoding mutations, as well as epimutations, converged on pathways that are important for prostate cancer, providing insights into this devastating disease. These discoveries underscore the importance of including population context in constructing comprehensive genomic maps for disease.

RESUMEN

Efficient utilization of solar energy for water evaporation is an advanced and environment-friendly technology to solve the crisis of global drinking water shortage. Herein, we report an efficient solar vapor generator comprised of a light-absorbing and photothermal hybrid compound [Ni(Phen) 3 ][V 14 O 34 Cl]Cl (NiV 14 ) confined in mesoporous and hydrophilic glass (meso-glass). The generator is floating in water by supporting on domestic melamine-formaldehyde (MF) foam to ensure the evaporation at water-air interface. Porous structures and poor thermal conductivity of the meso-glass together with MF foam contribute to the unfailing water supply, strong solar thermal localization and less heat dissipation, and convection. Associated with strong photothermal role of NiV 14 , these synergistic effects led to a water evaporation rate of 14.38 kg m -2 h -1 with total water evaporation efficiency of 111.4% under 6 suns and a daily solar water purification yield of 42.00 L m -2 under 1 sun irradiation. This solar evaporation system shows great promise for high-efficiency water purification application.

RESUMEN

Salt is a major abiotic stress that negatively impacts plant growth and development. Research on the mechanisms of plant salt tolerance and the breeding of salt-tolerant plants is becoming an important research field. Transcription factors are master regulators that control the expression of many target genes, helping to regulate the response of plants to adverse conditions. GRAS are plant-specific transcription factors that play various roles in plant development and stress responses. However, the function of a GRAS gene identified in Halostachys caspica, a salt-tolerant plant with important ecological value, has not been determined. In this study, we characterized a novel gene (HcSCL13) encoding a GRAS transcription factor from H. caspica. Quantitative real-time (qRT)-PCR results indicated that HcSCL13 expression was induced by salt, drought and application of stress-related phytohormone abscisic acid (ABA). The HcSCL13 protein was localized in the nucleus with transactivation activity at the N terminus. Heterologous overexpression of HcSCL13 enhanced plant growth and salt tolerance in transgenic Arabidopsis. With HcSCL13 overexpression, plants had enhanced growth, as well as greater chlorophyll content, fresh weight and root elongation compared to the wild type. Transcriptomic analysis revealed that HcSCL13 overexpression affected the response to light/abiotic stimulus/hormone/organic substance, plant hormone signal-related and plant growth and development genes under normal and saline stress conditions. Taken together, these results indicate that HcSCL13 genes can modulate salt stress tolerance in Arabidopsis through the regulation of plant growth and the activation of gene expression.

RESUMEN

BACKGROUND: There has been a paucity of data about the therapeutic efficacy of bronchoalveolar lavage (BAL) for pediatric refractory Mycoplasma pneumonia pneumonia (RMPP) complicated with atelectasis. This study aims to evaluate the clinical effectiveness and safety of BAL in pediatric RMPP inpatients complicated with atelectasis. METHODS: Totally 225 children diagnosed as having RMPP with radiological proven irreversible atelectasis completed this study. According to whether they received BAL treatment, they were divided into BAL-intervention group (n=125) and the control group (n=100). Clinical, laboratory and radiological effects were compared between these two groups. Bronchoscopic imaging features were also comprehensively investigated. RESULTS: Compared with control group, the febrile days after enrollment was significantly shorter in BAL-intervention group (3.0±1.6 d) compared with that in control group (4.1±1.7 d) (P<0.01). The duration of coughing was 3.1±1.7 d in BAL-intervention group and 4.6±1.8 days in the control group (P<0.01). The duration of abnormal lung auscultation was 3.8±1.8 d in intervention group and 5.8±1.6 d in the control group (P<0.01). The length of hospital stays was 5.8±1.6 days and 7.8±1.9 days (P<0.01), respectively. We also found that WBC count (P<0.01) and CRP value (P<0.01) recovered more quickly in BAL-intervention group compared with that in the control group. Seven days after admission, 85.6% of patients in BAL-intervention group showed atelectasis resolution versus 39.0% in control group (P<0.01), and for pleural effusion disappearance 78.4% versus 43.0% (P<0.01). CONCLUSIONS: Our data suggested that BAL intervention combined with regular drug usage and prednisolone is a better treatment for RMPP children complicated with atelectasis than conventional drug therapy alone.

RESUMEN

The remodeling of the left atrial morphology and function caused by atrial fibrillation (AF) can exacerbate thrombosis in the left atrium (LA) even spike up the risk of stroke within AF patients. This study explored the effect of the AF on hemodynamic and thrombosis in LA. We reconstructed the patient-specific anatomical shape of the LA and considered the non-Newtonian property of the blood. The thrombus model was applied in the LA models to simulate thrombosis. Our results indicate that AF can aggravate thrombosis which mainly occurs in the left atrial appendage (LAA). Thrombosis first forms on the LAA wall then expands toward the internal LAA. The proposed computational model also shows the potential application of numerical analyses to help assess the risk of thrombosis in AF patients.

RESUMEN

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a major cause of death with an increasing incidence at an epidemic rate. The existing treatments for T2DM lack long-term effective blood glucose control. In this study, the effects of miR-21 antagomir on T2DM and the related mechanism were investigated using streptozotocin (STZ)-induced T2DM rats. METHODS: 30 T2DM rats were randomly divided into 3 groups (n=10): T2DM group, T2DM rats with miR-21 antagomir group, T2DM rats with NC antagomir group. The expression of miR-21 in rats was detected by qRT-PCR. blood glucose, triacylglycerol (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-Cho), insulin, adiponectin, ITT and GTT were detected. The expression of TIMP3 in si-TIMP3 rats and the expression of TIMP3 in T2DM rats with miR-21 antagomir and si-TIMP3 was detected by Western blotting. RESULTS: We found that miR-21 antagomir reduced blood glucose concentration in T2DM rats. MiR21 antagomir improved lipid metabolic disorder by decreasing the levels of triacylglycerol (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-Cho) and increasing the level of high-density lipoprotein cholesterol (HDL-Cho). Also, miR-21 antagomir reduced the value of homeostasis model assessment of insulin resistance (HOMA-IR), hemoglobin A1c (HbAc1), plasma insulin, and up-regulated the plasma adiponectin. These results, combined with insulin tolerance tests (ITT) and glucose tolerance tests (GTT) results, showed that miR-21 improved insulin resistance in STZ-induced T2DM rats. Then the target relationship between miR-21 and tissue inhibitor of metalloproteinases 3 (TIMP3) was proved by luciferase reporter assay. More impressively, miR-21 significantly increased the expression level of TIMP3 in STZ-induced T2DM rats. CONCLUSIONS: Our study taken together has shown that miR-21 antagomir improved insulin resistance and lipid metabolism disorder in STZ-induced T2DM rats by up-regulating the expression level of TIMP3. This study suggested that miR-21 antagomir could be used as an effective therapeutic strategy and the underlying mechanism was revealed.

RESUMEN

The purpose of this study was to investigate the association between refined grains intake and obesity in China. Refined grain intake was considered in relation to energy intake and at varied levels of macronutrient distribution. A cross-sectional study of 6913 participants was conducted using internet-based dietary questionnaire for Chinese (IDQC). The associations and dose-response relationships between refined grains intake and obesity were investigated using multivariable logistic regression analyses and restricted cubic spline (RCS) models. There was a positive association between refined grains intake and abdominal obesity for all participants (forth quartile OR, 1.313; 95% CI, 1.103-1.760; p < .05) and this association persisted in low energy, low carbohydrate, high fat and high protein level subgroups. A range of favourable refined grains intake was 88-116 g/d (3-4 servings/d), which might decrease the likelihood of obesity for Chinese residents. Further prospective studies are needed to confirm these findings.

RESUMEN

Long non-coding RNAs (lncRNAs) is a class of eukaryotic transcripts with length of more than 200 bp. They contribute to the regulation of gene expressions involved in multiple processes including the skin cell proliferation, differentiation, and reconstruction of the secondary hair follicles (SHFs). In this study, firstly, we identified 16 putative lncRNAs from SHFs of cashmere goat based on the EST sequences from NCBI database. Secondly, we investigated their transcriptional pattern in SHFs of cashmere goat, and constructed their ceRNA regulatory networks. The RT-qPCR results showed four lncRNAs (lncRNA-475074, -052149, -052140, and -051789) were significantly up-regulated, and nine lncRNAs (lncRNA-711032, -475083, -475070, -052139, -052127, -052037, -051903, -051847, and -051804) were significantly down-regulatd in anagen SHFs of cashmere goat. CeRNA networks analysis revealed complex interactional relationship among lncRNAs, miRNAs and mRNAs. Further, the KEGG pathway enrichment was performed for the potential target genes of the identified lncRNAs based on bioinformatics technique, and the results indicated that differentially expressed lncRNAs directly or indirectly might regulate potential target genes. Our results from this study will provide a significant information for further exploring the functions and possible mechanisms of the identified lncRNAs in SHFs of cashmere goat.

RESUMEN

NH3 emission has become one of the key factors for aerobic composting of animal manure. It has been reported that adding microbial agents during aerobic composting can reduce NH3 emissions. However, environmental factors have a considerable influence on the activity and stability of the microbial agent. Therefore, this study used cornstalk biochar as carriers to find out the better biological immobilization method to examine the mitigation ability and mechanism of NH3 production from laying hen manure composting. The results from different immobilized methods showed that NH3 was reduced by 12.43%, 5.53%, 14.57%, and 22.61% in the cornstalk biochar group, free load bacteria group, mixed load bacteria group, and separate load bacteria group, respectively. Under the simulated composting condition, NH3 production was 46.52, 38.14, 39.08, and 30.81 g in the treatment of the control, mixed bacteria, cornstalk biochar, and cornstalk biochar separate load immobilized mixed bacteria, respectively. The cornstalk biochar separate load immobilized mixed bacteria treatment significantly reduced NH3 emission compared with the other treatments (p < 0.05). Compared with the control, adding cornstalk biochar immobilized mixed bacteria significantly decreased the electrical conductivity, water-soluble carbon, total nitrogen loss, and concentration of ammonium nitrogen (p < 0.05), and significantly increased the seed germination rate, total number of microorganisms, and relative abundance of lactic acid bacteria throughout the composting process (p < 0.05). Therefore, the reason for the low NH3 emission might be due not only to the adsorption of the cornstalk biochar but also because of the role of complex bacteria, which increases the relative abundance of lactic acid bacteria and promotes the acid production of lactic acid bacteria to reduce NH3 emissions. This result revealed the potential of using biological immobilization technology to reduce NH3 emissions during laying hen manure composting.

RESUMEN

Effectively representing Medical Subject Headings (MeSH) headings (terms) such as disease and drug as discriminative vectors could greatly improve the performance of downstream computational prediction models. However, these terms are often abstract and difficult to quantify. In this paper, we converted the MeSH tree structure into a relationship network and applied several graph embedding algorithms on it to represent these terms. Specifically, the relationship network consisting of nodes (MeSH headings) and edges (relationships), which can be constructed by the tree num. Then, five graph embedding algorithms including DeepWalk, LINE, SDNE, LAP and HOPE were implemented on the relationship network to represent MeSH headings as vectors. In order to evaluate the performance of the proposed methods, we carried out the node classification and relationship prediction tasks. The results show that the MeSH headings characterized by graph embedding algorithms can not only be treated as an independent carrier for representation, but also can be utilized as additional information to enhance the representation ability of vectors. Thus, it can serve as an input and continue to play a significant role in any computational models related to disease, drug, microbe, etc. Besides, our method holds great hope to inspire relevant researchers to study the representation of terms in this network perspective.

RESUMEN

The outbreak of COVID-19 in China in December 2019 has been identified as a pandemic and a health emergency of global concern. Our objective was to investigate the prevalence and predictors of posttraumatic stress symptoms (PTSS) in China hardest-hit areas during COVID-19 outbreak, especially exploring the gender difference existing in PTSS. One month after the December 2019 COVID-19 outbreak in Wuhan China, we surveyed PTSS and sleep qualities among 285 residents in Wuhan and surrounding cities using the PTSD Checklist for DSM-5 (PCL-5) and 4 items from the Pittsburgh Sleep Quality Index (PSQI). Hierarchical regression analysis and non-parametric test were used to analyze the data. Results indicated that the prevalence of PTSS in China hardest-hit areas a month after the COVID-19 outbreak was 7%. Women reported significant higher PTSS in the domains of re-experiencing, negative alterations in cognition or mood, and hyper-arousal. Participants with better sleep quality or less frequency of early awakenings reported lower PTSS. Professional and effective mental health services should be designed in order to aid the psychological wellbeing of the population in affected areas, especially those living in hardest-hit areas, females and people with poor sleep quality.
