Comparison of microRNAs in the intramuscular adipose tissue from Jinhua and Landrace pigs

MicroRNA (miRNA) is critically involved in lipogenesis occurring in various body parts of humans and animals. In this study, to further investigate the role and distribution of miRNA in porcine intramuscular adipose tissue, small RNAs were extracted from Jinhua and Landrace pigs to identify the expression profiles of miRNAs. miRNA expression profiles revealed that 558 miRNAs including 287 known and 271 novel miRNAs were identified, and 220 of them showed differential expression in the pigs. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis suggested that the target genes of the differentially expressed miRNAs were involved in fatty metabolism. In conclusion, the current study reveals the active participation of miRNAs in the regulation of adipogenesis in the intramuscular adipose tissue of Jinhua and Landrace pigs.
The efficacy and safety of first-line therapies for preventing chronic post-surgical pain: a network meta-analysis

Background Due to conflicting evidence regarding first-line therapies for chronic post-surgical pain (CPSP), here we comparatively evaluated the efficacy and safety of first-line therapies for the prevention of CPSP. Materials and Methods MEDLINE, EMBASE, and Cochrane CENTRAL databases were searched for randomized, controlled trials (RCTs) of systemic drugs measuring pain three months or more post-surgery. Pairwise meta-analyses (a frequentist technique directly comparing each intervention against placebo) and network meta-analyses (a Bayesian technique simultaneously comparing several interventions via an evidence network) compared the mean differences for primary efficacy (reduction in all pain), secondary efficacy (reduction in moderate or severe pain), and primary safety (drop-out rate from treatment-related adverse effects). Ranking probabilities from the network meta-analysis were transformed using surface under the cumulative ranking analysis (SUCRA). Sensitivity analyses evaluated the impact of age, gender, surgery type, and outlier studies. Results Twenty-four RCTs were included. Mexiletine and ketamine ranked highest in primary efficacy, while ketamine and nefopam ranked highest in secondary efficacy. Simultaneous SUCRA-based rankings of the interventions according to both efficacy and safety revealed that nefopam and mexiletine ranked highest in preventing CPSP. Through the sensitivity analyses, gabapentin and ketamine remained the most-highly-ranked in terms of efficacy, while nefopam and ketamine remained the most-highly-ranked in terms of safety. Conclusions Nefopam and mexiletine may be considered as first-line therapies for the prevention of CPSP. On account of the paucity of evidence available on nefopam and mexiletine, gabapentin and ketamine may also be considered. Venlafaxine is not recommended for the prevention of CPSP.
Patient and Practice Trends in Total Ankle Replacement and Tibiotalar Arthrodesis in the United States From 2007 to 2013

Introduction: Both total ankle replacement (TAR) and tibiotalar arthrodesis (TTA) are used in the surgical management of ankle arthritis. Over the past decade, TAR instrumentation, techniques, and implants have improved, making the procedure more reliable and reproducible, thus making TAR more common. Methods: The Nationwide Inpatient Sample database from 2007 to 2013 was used to obtain data on patients elder than 50 years who underwent either TAR or TTA. Differences in temporal, demographic, and diagnosis trends between TAR and TTA were analyzed. Results: Between 2007 and 2013, 15,060 patients underwent TAR and 35,096 underwent TTA. Patients undergoing TTA had significantly more comorbidities (2.17 versus 1.55; P < 0.001). The share of TAR performed increased significantly from 2007 (14%) to 2013 (45%) (P < 0.001). From 2007 to 2013, we found a 12-fold increase in the odds of having a TAR for patients with posttraumatic osteoarthritis (P < 0.001), a 4.9-fold increase for those with primary osteoarthritis, and a 3.1-fold increase for patients with rheumatoid arthritis (P < 0.001). Conclusions: Over the past decade, the frequency of TAR has increased, particularly in patients with posttraumatic arthritis and osteoarthritis. Surgeons still perform TAR in healthier patients compared with TTA; however, because surgeons become more experienced with the technique, patients are undergoing TAR at a markedly higher rate. Level of Evidence: Level III: retrospective comparative study
Pilot investigation of a novel white matter imaging technique in Veterans with and without history of mild traumatic brain injury

ABSTRACT Objective: The objective of this study is to assess utility of in vivo myelin imaging in combat Veterans with and without history of mild traumatic brain injury (mTBI). We hypothesized that those with history of mTBI would have lower myelin water fraction (MWF), a marker of myelin integrity and content, than those without, and lower MWF would be associated with worse speeded attention/processing speed. Research design: Combat Veterans (N = 70) with (n = 42) and without history of mTBI (n = 28) underwent neuroimaging including a novel myelin-sensitive magnetic resonance imaging technique (multicomponent-driven equilibrium single-pulse observation of T1/T2; mcDESPOT) and comprehensive neuropsychological assessment. Results: There were no group differences in MWF using a region-of-interest approach. An exploratory analysis applying limited spatial constraints, however, revealed significantly more ‘potholes’ (clusters of low MWF) in Veterans with history of mTBI compared to those without. Lower MWF across several ROIs was associated with worse performance on a speeded attention task across groups. Conclusion: Veterans in the post-acute period following mTBI showed limited and spatially heterogeneous MWF changes and myelin integrity was significantly related to processing speed. This preliminary evidence for usefulness of mcDESPOT in combat Veterans with history of mTBI warrants future research to determine mcDESPOT’s relative utility compared to techniques such as diffusion tensor imaging.
Racial/Ethnic Disparities in Tobacco Product Use Among Middle and High School Students — United States, 2014–2017

During the past few decades, wide disparities in tobacco product use have been documented among the largest racial/ethnic groups in the United States (1,2); however, little is known about tobacco product use among youths from racial/ethnic groups other than whites, blacks, and Hispanics. Surveillance reports typically aggregate these racial/ethnic minorities into a single category because of small sample sizes (3). To assess tobacco product use among U.S. middle and high school students from seven racial/ethnic groups (non-Hispanic whites [whites], non-Hispanic blacks [blacks], Hispanics, non-Hispanic Asians [Asians], non-Hispanic American Indian/Alaska natives [AI/ANs], non-Hispanic Native Hawaiians/Other Pacific Islanders [NHOPIs], and non-Hispanic multiracial persons [multiracial]), CDC analyzed pooled data from the 2014–2017 National Youth Tobacco Surveys (NYTS). Prevalence of ever (≥1 time in lifetime) and current (≥1 time in past 30 days) use of seven tobacco products (cigarettes, cigars, smokeless tobacco, electronic cigarettes [e-cigarettes], hookahs, pipes, and bidis) was assessed; any tobacco product use was defined as use of one or more tobacco products, including hand-rolled cigarettes. During 2014–2017, ever-use of any tobacco product among U.S. middle and high school students was as follows: NHOPIs (45.1%), AI/ANs (43.8%), multiracial persons (38.2%), Hispanics (35.1%), blacks (32.3%), whites (32.0%), and Asians (16.3%). Current use of any tobacco product was as follows: NHOPIs (23.4%), AI/ANs (20.6%), multiracial persons (16.5%), whites (15.3%), Hispanics (14.6%), blacks (11.5%), and Asians (5.0%). Among black middle and high school students, cigars were the most common product currently used, whereas e-cigarettes were the most commonly used product for all other racial/ethnic groups. Comprehensive and sustained implementation of evidence-based, population-level tobacco control interventions could reduce prevalence and disparities in tobacco product use among U.S. youths.
Differential biochemical properties of three canonical Dps proteins from the cyanobacterium Nostoc punctiforme suggest distinct cellular functions

DNA-binding proteins from starved cells (Dps, EC: 1.16.3.1) have a variety of different biochemical activities such as DNA-binding, iron sequestration, and H2O2 detoxification. Most bacteria commonly feature one or two Dps enzymes, whereas the cyanobacterium Nostoc punctiforme displays an unusually high number of five Dps proteins (NpDps1–5). Our previous studies have indicated physiological differences, as well as cell-specific expression, among these five proteins. Three of the five NpDps proteins, NpDps1, -2, and -3, were classified as canonical Dps proteins. To further investigate their properties and possible importance for physiological function, here we characterized and compared them in vitro. Nondenaturing PAGE, gel filtration, and dynamic light-scattering experiments disclosed that the three NpDps proteins exist as multimeric protein species in the bacterial cell. We also demonstrate Dps-mediated iron oxidation catalysis in the presence of H2O2. However, no iron oxidation with O2 as the electron acceptor was detected under our experimental conditions. In modeled structures of NpDps1, -2, and -3, protein channels were identified that could serve as the entrance for ferrous iron into the dodecameric structures. Furthermore, we could demonstrate pH-dependent DNA-binding properties for NpDps2 and -3. This study adds critical insights into the functions and stabilities of the three canonical Dps proteins from N. punctiforme and suggests that each of the Dps proteins within this bacterium has a specific biochemical property and function.
Activation Toll-Like Receptor7 (TLR7) Responsiveness Associated with Mitogen- Activated Protein Kinase (MAPK) Activation in HIOEC Cell Line of Oral Squamous Cell Carcinoma

Statement of the Problem: Oral squamous cell carcinoma is the most common oral malignancy. Toll-like receptor (TLR) activation led to alterations in the levels of mRNA encoding the TLR accountable for recognizing the inducing agonist and cross-regulation of other TLR. Purpose: The purpose of this study is determination of mitogen-associated protein kinase (MAPK) activation in human immortalized oral epithelial cell (HIOEC) line via up regulating of TLR7. Materials and Method: expression of TLR7 was measured in HIOEC and normal cells by quantitative real-time polymerase chain reaction (qRT-PCR) and samples were calibrated by β-actin. Results: Western blot analysis discovered high expression of TLR7 and MAPK in HIOEC cell lines. TLR7 was over-expressed in HIOEC cell line. Imiquimod-induced expression of interleukin (IL)-6, IL-8, and vascular endothelial growth factor (VEGF) was inhibited by TLR7 siRNA in HIOEC cells as determined by reverse transcription polymerase chain reaction (RT-PCR). Mean fluorescence intensity of nuclear p38 expression was determined in HIOEC cell lines (p< 0.05). RT-PCR analysis of IL-6, IL-8, and VEGF mRNA expression in HIOEC cells stimulated with imiquimod (1 μg/ml) for indicated time points. Conclusion: TLR7 is functionally over-expressed in HIOEC cell line of oral squamous cell carcinoma and development of resistance to cisplatin in human oral squamous cell carcinoma might occur through the mechanism involving activation of TLR7 and its dependent signaling pathway.
LncRNA WTAPP1 Promotes Migration and Angiogenesis of Endothelial Progenitor Cells via MMP1 Through MicroRNA 3120 and Akt/PI3K/Autophagy Pathways

Efficient recruitment and angiogenesis of endothelial progenitor cells (EPCs) are critical during a thrombus event. However, the details of EPC recruitment and the regulation of angiogenesis have not been fully determined. The aim of this study was to determine the role of the long noncoding (lnc)RNA Wilms tumor 1 associated protein pseudogene 1 (WTAPP1) in regulation of the migration and angiogenesis of EPCs. EPCs were isolated from human peripheral blood and characterized by flow cytometry, after which lentivirus‐mediated lncRNA WTAPP1 overexpression and knockdown were performed. Scratch assay, Transwell assay, and in vitro and in vivo tube formation assays were performed to measure cell migration, invasion, and angiogenic abilities, respectively. Moreover, a microarray screen, bioinformatic prediction, and quantitative PCR and Western blot of miRNAs interacting with lncRNA WTAPP1 were conducted. Western blot was carried out to elucidate the relationship among WTAPP1, miR‐3120‐5P, and MMP‐1 in the autophagy pathway. WTAPP1 positively regulated migration, invasion, and in vitro and in vivo tube formation in EPCs by increasing MMP‐1 expression and activating PI3K/Akt/mTOR signaling. Furthermore, WTAPP1 contains a putative miR‐3120‐5P binding site. Suppression of WTAPP1 by miR‐3120‐5P decreased the level of MMP‐1. In addition, we demonstrated that suppression of the autophagy pathway is involved in the effects of WTAPP1 on EPC migration and angiogenesis. The lncRNA WTAPP1, a molecular decoy for miR‐3120‐5p, regulates MMP‐1 expression via the PI3K/Akt and autophagy pathways, thereby mediating cell migration and angiogenesis in EPCs. Acting as a potential therapeutic target, the lncRNA WTAPP1 may play an important role in the pathogenesis of DVT. Stem Cells 2018;36:1863–12
Racial and Ethnic Differences in the Relationship between Aspirin Use and Non–Small Cell Lung Cancer Risk and Survival

Background: African Americans (AA) experience higher incidence and mortality of lung cancer as compared with European Americans (EA). Inflammation is associated with lung cancer, many aspects of which differ between AA and EA. We investigated whether use, frequency, and duration of the anti-inflammatory drug aspirin were associated with lung cancer risk and survival, separately among AA and EA populations. Methods: Using data from the Maryland Non–Small Cell Lung Cancer (NSCLC) Case–Control Study (1,220 cases [404 AA and 816 EA] and 1,634 controls [1,004 EA and 630 AA]), we estimated the adjusted odds ratios (OR) and hazard ratios (HR) with 95% confidence intervals (CI) of the associations between aspirin use and NSCLC risk and survival, respectively. Results: Any aspirin use (OR: 0.66; 95% CI, 0.49–0.89), daily use of ≥ 1 tablet (OR: 0.68; 95% CI, 0.50–0.90), and use for ≥ 3 years (OR: 0.61; 95% CI, 0.44–0.85) was associated with lower NSCLC risk only among men, even after adjustment for covariates including body mass index and global genetic ancestry. These variables were also associated with improved survival, but only among AA (HR: 0.64; 95% CI, 0.46–0.91; HR: 0.61; 95% CI, 0.42–0.90; and HR: 0.60; 95% CI, 0.39–0.92, respectively). Tylenol and other NSAIDs were either associated with elevated or no NSCLC risk. Conclusions: Aspirin use is associated with lower risk of NSCLC among men and improved survival among AA. Impact: Preventive regular aspirin use could be considered among men and AA.
Prevalence and risk factors for upper gastrointestinal diseases in health check-up subjects: a nationwide multicenter study in Korea

Abstract Objectives: The prevalence of upper gastrointestinal disease is expected to change following advances in socioeconomic status and improved hygiene in Korea. The aim of this study was to investigate the recent trends in upper gastrointestinal diseases based on endoscopic findings and Helicobacter pylori (H. pylori) seroprevalence in subjects undergoing health check-up at tertiary centers in Korea. Methods: A multicenter cross-sectional study was conducted at nine healthcare centers between September 2016 and June 2017. The subjects were evaluated using questionnaires, upper endoscopy and H. pylori serology tests. The results were compared with previous data in our study group obtained from eight tertiary healthcare centers in 2011 (n = 4023). Results: In total, we prospectively enrolled 2504 subjects undergoing health check-up. The prevalence of reflux esophagitis (RE) was 9.7%, which showed an increasing but insignificant trend since 2011 (8.8%). The prevalence of active and healing-stage benign gastric ulcer and duodenal ulcer (DU) was 1.6% and 1.2%, respectively, which confirmed a significant decrease since 2011 (4.1%; p < .001 and 2.2%; p = .005, respectively). The prevalence of gastric cancer was 0.5%, representing an increasing trend since 2011 (0.12%; p = .003). H. pylori seroprevalence was 51.3%, which significantly decreased from 2011 (59.8%; p < .001). In multivariate analysis, H. pylori seropositivity was a significant risk factor for DU (p < .001), whereas a significant protective factor against RE (p < .001). Conclusions: The significant decrease of H. pylori seroprevalence in the past five years altered the incidence of upper gastrointestinal disease.
Monotherapy of experimental metabolic syndrome: II. Study of cardiovascular effects

Abstract Metabolic syndrome belongs to the most important risk factors of cardiovascular diseases. The aim of this study was to investigate changes in cardiovascular system induced by high cholesterol and high fat diet (HCHF) in HTG rats and their influence by a pyridoindole antioxidant – SMe1EC2 (S). The effects of S were compared with those of atorvastatin (A). Male HTG rats were fed HCHF (1% cholesterol + 7.5% lard) for 4 weeks. S and A were administered p.o. , 50 mg/kg b.w. Following experimental groups were used: Wistar rats (W), hypertriglyceridemic rats (HTG), HTG rats fed HCHF (CHOL), HTG+S (S-HTG), CHOL+S (S-CHOL), and CHOL+A (A-CHOL). Values of blood pressure (BP) and selected ECG parameters were monitored in conscious animals, functions of the isolated heart and aorta were analyzed ex vivo. At the end of the experiment, systolic (sBP) and diastolic (dBP) blood pressure was increased in HTG and CHOL. S and A decreased BP in all treated groups. Accordingly with BP changes, the aortic endothelial function of CHOL was damaged. Both S and A administration ameliorated the endothelium-dependent relaxation to values of W. PQ and QTc intervals were prolonged in CHOL, while the treatment with S or A improved ECG findings. Prodysrhythmogenic threshold was decreased significantly in CHOL and both treatments returned it to the control values. In conclusion, HCHF increased BP, impaired endothelial relaxation of the aorta and potentiated susceptibility of myocardium to dysrhythmias. The effect of S on the changes induced by HCHF diet was more pronounced than that of A.
A comprehensive evaluation of the genetic architecture of sudden cardiac arrest

Aims Sudden cardiac arrest (SCA) accounts for 10% of adult mortality in Western populations. We aim to identify potential loci associated with SCA and to identify risk factors causally associated with SCA. Methods and results We carried out a large genome-wide association study (GWAS) for SCA (n = 3939 cases, 25 989 non-cases) to examine common variation genome-wide and in candidate arrhythmia genes. We also exploited Mendelian randomization (MR) methods using cross-trait multi-variant genetic risk score associations (GRSA) to assess causal relationships of 18 risk factors with SCA. No variants were associated with SCA at genome-wide significance, nor were common variants in candidate arrhythmia genes associated with SCA at nominal significance. Using cross-trait GRSA, we established genetic correlation between SCA and (i) coronary artery disease (CAD) and traditional CAD risk factors (blood pressure, lipids, and diabetes), (ii) height and BMI, and (iii) electrical instability traits (QT and atrial fibrillation), suggesting aetiologic roles for these traits in SCA risk. Conclusions Our findings show that a comprehensive approach to the genetic architecture of SCA can shed light on the determinants of a complex life-threatening condition with multiple influencing factors in the general population. The results of this genetic analysis, both positive and negative findings, have implications for evaluating the genetic architecture of patients with a family history of SCA, and for efforts to prevent SCA in high-risk populations and the general community.
Clinical cosmeceutical repurposing of melatonin in androgenic alopecia using nanostructured lipid carriers prepared with antioxidant oils

ABSTRACT Background: The present work aims to formulate nanostructured lipid carriers (NLCs) exhibiting high skin deposition and high inherent antioxidant potential to repurpose the use of melatonin hormone and some antioxidant oils in the treatment of androgenic alopecia (AGA). Research design and methods: NLCs were characterized for their size, charge, drug entrapment, anti-oxidant potential, physical stability, in vitro release, surface morphology, and ex-vivo skin deposition. Their merits were clinically tested on patients suffering from AGA by calculating the degree of improvement, conduction of hair pull test, histometric assessment, and dermoscopic evaluation. Results: Results revealed that melatonin NLCs showed nanometer size, negatively charged surface, high entrapment efficiency, and high anti-oxidant potential, in addition to sustained release for 6 h. Furthermore, NLCs displayed good storage stability and they were able to increase the skin deposition of melatonin 4.5-folds in stratum corneum, 7-folds in epidermis, and 6.8-folds in the dermis compared to melatonin solution. Melatonin NLCs displayed more clinically desirable results compared to the melatonin solution in AGA patients, manifested by increased hair density and thickness and decreased hair loss. Conclusions: The aforementioned system was shown to be a very promising treatment modality for AGA, which is worthy of futuristic experimentation.
An F-type lectin domain directs the activity of Streptosporangium roseum alpha-L-fucosidase

F-type lectins are phylogenetically widespread but selectively distributed fucose-binding lectins with L-fucose- and calcium-binding sequence motifs and an F-type lectin fold. Bacterial F-type lectin domains frequently occur in tandem with various protein domains in diverse architectures, indicating a possible role in directing enzyme activities or other biological functions to distinct fucosylated niches. Here, we report the biochemical characterization of a Streptosporangium roseum protein containing an F-type lectin domain in tandem with an NPCBM-associated domain and a family GH 29A alpha-l-fucosidase domain. We show that the F-type lectin domain of this protein recognizes fucosylated glycans in both α and β linkages but has high affinity for a Fuc-α-1,2-Gal motif and that the alpha-l-fucosidase domain displays hydrolytic activity on glycan substrates with α1-2 and α1-4 linked fucose. We also show that the F-type lectin domain does not have any effect on the activity of the cis-positioned alpha-l-fucosidase domain with the synthetic substrate, 4-Methylumbelliferyl-alpha-l-fucopyranoside or on inhibition of this activity by l-fucose or deoxyfuconojirimycin hydrochloride. However, the F-type lectin domain together with the NPCBM-associated domain enhances the activity of the cis-positioned alpha-l-fucosidase domain for soluble fucosylated oligosaccharide substrates. While there are many reports of glycoside hydrolase activity towards insoluble and soluble polysaccharides being enhanced by cis-positioned carbohydrate binding modules on the polypeptide, this is the first report, to our knowledge, of enhancement of activity towards aqueous, freely diffusible, small oligosaccharides. We propose a model involving structural stabilization and a bind-and-jump action mediated by the F-type lectin domain to rationalize our findings.
