Clade 2 SS2 strains presented high genetic similarity to SS3 and SS7 and shared common competence and defensive elements with them but were significantly different from Clade 1 SS2 strains. Notably, although the cps loci shared by Clade 1 and 2 SS2 strains were almost identical, a specific region of the cps locus of strain NSUI002 (Clade 2 SS2) could be found in the SS3 cps locus but not in the Clade 1 SS2 strain. These data indicated that the SS2 strains in CC28 and CC29 might have acquired the cps locus through capsule switching, which could explain the distinct genetic lineages within the SS2 population.Bipolar disorder (BD) is a complex illness with variability at the level of symptom presentation, clinical course, cognitive capacity, and everyday function. Cognition is a key predictor of functional disability in BD, however, much remains unknown about the development and presentation of cognitive dysfunction in BD. Studies have shown that 30-50% of affectively stable people with BD are indistinguishable from healthy individuals in terms of cognitive presentation. In contrast, many people with BD have moderate to severe cognitive deficits, in some cases on par with what is typically observed in schizophrenia (SZ). Recent research efforts have aimed to parse this cognitive heterogeneity using unsupervised statistical techniques, resulting in more homogeneous subgroups. This method has provided new insights into the clinical and biological predictors of a potentially - neuroprogressive - declinin - gcognitive course in BD. Future studies that include detailed longitudinal follow-up in large BD cohorts hold promise for guiding the development of novel treatments that reach beyond the primary affective symptoms and target functionally relevant outcomes to promote full recovery.
Atherosclerosis is the most prominent underlying cause of cardiovascular disease (CVD). It is initiated by cholesterol deposition in the arterial intima, which causes macrophage recruitment and proinflammatory responses that promote plaque growth, necrotic core formation, and plaque rupture. Lipin-1 is a phosphatidic acid phosphohydrolase for glycerolipid synthesis. We have shown that lipin-1 phosphatase activity promotes macrophage pro-inflammatory responses when stimulated with modified low-density lipoprotein (modLDL) and accelerates atherosclerosis. Lipin-1 also independently acts as a transcriptional co-regulator where it enhances the expression of genes involved in β-oxidation. In hepatocytes and adipocytes, lipin-1 augments the activity of transcription factors such as peroxisome proliferator-activated receptor (PPARs). PPARs control the expression of anti-inflammatory genes in macrophages and slow or reduce atherosclerotic progression. Therefore, we hypothesize myeloid-derived lipin-1 transcriptional co-regulatory activity reduces atherosclerosis.

We used myeloid-derived lipin-1 knockout (lipin-1mKO) and littermate control mice and AAV8-PCSK9 along with high-fat diet to elicit atherosclerosis.

Lipin-1mKO mice had larger aortic root plaques than littermate control mice after 8 and 12 weeks of a high-fat diet. Lipin-1mKO mice also had increased serum proinflammatory cytokine concentrations, reduced apoptosis in plaques, and larger necrotic cores in the plaques compared to control mice.

Combined, the data suggest lipin-1 transcriptional co-regulatory activity in myeloid cells is atheroprotective.

EV encapsulate bioactive molecules, and the molecular cargo is determined by the trigger stimulating its release, reflecting its cell origin and biological functions. This review is primarily focused on the latest evidence of the roles of EV, released from cells involved in the different stages of atherothrombosis. The potential translation of this information to the clinical arena is also discussed. EV can have both pro- and anti-atherothrombotic effects depending on several factors, such as the type of vesicle (MV/exosome), its molecular cargo, its cell of origin, and the context in which are generated, i.e., the stimulus triggering its release. In fact, EV actively participate in every step of atherosclerosis onset and progression, and also in thrombus formation leading to a major adverse cardiovascular event. Moreover, EV have a determinant role in fibrous cap stability, thus determining the propensity of the plaque to rupture. On the other hand, and again, conditioned by the context and stimulus instigating its secretion, some EV may have protective biological functions, perhaps as a compensatory mechanism or even with reparative or regenerative potential. Therefore, the study of the implication of EV in atherothrombosis might be of relevance to unveil new therapeutic targets, vectors and biomarkers of cardiovascular disease (CVD).Internet addiction (IA), which can have different development patterns, is considered a serious problem among adolescents. Due to the increasing number of adolescent internet users in Mainland China, professionals are obligated to investigate the prevalence and predictors of IA persistence and incidence. This study investigated the prevalence of IA persistence and incidence among 1301 students in Mainland China across two years using a two-wave longitudinal design. IDO inhibitor Of the 187 students with IA in 7th grade, 40.64% had a persisting addiction by grade 9. Of the 1114 students without an IA in 7th grade, 10.32% had developed an IA by grade 9. Multilevel logistic regression analyses indicated that higher levels of depressive symptoms (odds ratio = 1.04; p = .04) and maternal education (odds ratio = 2.23; p = .01) could increase the likelihood of IA persistence. Significant predictors of IA incidence were being male (odds ratio = 0.59; p = .03), being an only child (odds ratio = 1.91; p = .01), having a low family income (odds ratio = 1.21; p less then .001), and experiencing school maladjustment (odds ratio = 1.01; p less then .01).Alpha1-antitrypsin deficiency (AATD) is caused by mutations in the SERPINA1 gene, coding for alpha1-antitrypsin (AAT). AAT is synthesised mainly in the liver and is released into bloodstream to protect tissues (particularly lung) with its antiprotease activity. The homozygous Pi∗Z mutation (Pi∗ZZ genotype) is the predominant cause of severe AATD. It interferes with AAT secretion thereby leading to AAT accumulation in the liver and lack of AAT in the circulation and the lung. Accordingly, Pi∗ZZ individuals are strongly predisposed to lung and liver injury. The former is treated by a weekly AAT augmentation therapy, but not medicinal products exist for the liver. Our review summarises the current approaches silencing AAT production, improving protein folding and secretion or promoting AAT degradation.Bleomycin (BLM) is used as an anti-cancer drug clinically. However, some cancer cells are resistant to BLM, which limits the usage of BLM in chemotherapy. But the underlying mechanism of such resistance is poorly understood. Here we show that the ATP binding cassette (ABC) transporter ABCC3 is required for the BLM-resistance in Arabidopsis. link2 In a genetic screen for ddrm (DNA damage response mutants), we found that loss of ABCC3 confers the hypersensitivity to BLM. link3 In contrast, overexpression of ABCC3 enhances the resistance to BLM. We further found that the expression of ABCC3 is induced by BLM, which is dependent on the protein kinase ATM and the transcription factor SOG1, two master regulators of DNA damage response. Our study revealed that the ABC transporter contributes to BLM-resistance, indicating that the combination of ABC transporter inhibitors and BLM may enhance the efficacy of BLM in cancer therapy.
In the acute phase of acute myocardial infarction (AMI), reperfusion ventricular arrhythmias such as ventricular tachycardia and ventricular fibrillation (Reperfusion VT/VF) resulting from reperfusion injury are one of the causes of in-hospital death. Predicting Reperfusion VT/VF is clinically important. Previous studies have reported that oxidative stress is the cause of reperfusion injury and reperfusion arrhythmia. There are also reports that xanthine oxidase inhibitors have the effect of preventing reperfusion arrhythmia. We hypothesized that hyperuricemia is a risk factor for reperfusion arrhythmias in AMI. The aim of our study is to investigate whether serum uric acid is associated with Reperfusion VT/VF in acute myocardial infarction.

This is a single-center, retrospective cohort study. We enrolled 612 ST elevation myocardial infarction patients who underwent successful primary percutaneous coronary intervention (PCI). We divided patients into a high serum uric acid group (HUA group) and a low serum uric acid group (LUA group) with a cutoff value of 7.0mg/dl, which is the standard value of serum uric acid. We compared the frequency of Reperfusion VT/VF in both groups.

There were 111 patients in the HUA group and 512 patients in the LUA group. Creatinine tended to be higher in the HUA group than in the LUA group. (1.12±0.41mg/dl VS 0.92±1.10mg/dl P=0.06). The frequency of Reperfusion VT/VF was significantly higher in the HUA group than in the LUA group (17.1% VS 4.0% P<0.001).

Elevated serum uric acid is associated with higher frequency of reperfusion ventricular arrhythmia.

Birthweight is an indicator of fetal growth and environmental-related alterations of birthweight have been linked with multiple disorders and conditions progressing into adulthood. Although a few studies have assessed the association between birthweight and the totality of exogenous exposures and their downstream molecular responses in maternal urine and cord blood; no prior research has considered a) the maternal serum prenatal metabolome, which is enriched for hormones, and b) non-linear and synergistic associations among exposures.

We measured the maternal serum metabolome during pregnancy using an untargeted metabolomics approach and birthweight for gestational age (BWGA) z-score in 410 mother-child dyads enrolled in the PRogramming of Intergenerational Stress Mechanisms (PRISM) cohort. We leveraged a Bayesian factor analysis for interaction to select the most important metabolites associated with BWGA z-score and to evaluate their linear, non-linear and non-additive associations. We also assessed theearly and synergistically to variation in newborn birthweight.An increasing number of studies have linked ambient air pollution to chronic kidney disease (CKD) prevalence. However, its potential effect modification by urbanization has not been investigated. Based on data of 47,204 adults from the China National Survey of Chronic Kidney Disease (CKSCKD) dataset, night light satellite remote sensing data and high-resolution air pollution inversion products, the present cross-sectional study investigated the association between fine particulate matter less then 2.5 mm in diameter (PM2.5), nitrogen dioxide (NO2), night light index (NLI) and CKD prevalence in China, and the effect modification by urbanization characterized by administrative classification and NLI on the pollutant-health associations. Our results showed that a 10-μg/m3 increase in PM2.5 at 3-year moving average, a 10-μg/m3 increase in NO2 at 5-year moving average, and a 10-U increase in NLI at 5-year moving average were significantly associated with increased odds of CKD prevalence [OR = 1.24 (95 %CI1.14, 1.
