In vivo study showed that lenalidomide inhibited pro-inflammatory cytokines TNF-α and IL-6 while enhanced anti-fibrotic cytokines IFN-γ and IL-10 in bleomycin-induced inflammation model, and attenuated pulmonary fibrosis and collagen deposition in the following fibrosis stage. In conclusion, our results demonstrate that lenalidomide possesses potential anti-fibrotic effects through suppressing NF-κB signaling.

Bronchopulmonary dysplasia (BPD) is a serious respiratory complication in premature infants and moderate-to-severe BPD may affect the long-term quality of life and lack of specific treatment once it happened. Therefore, it is necessary to identify early diagnostic biomarkers for moderate-to-severe BPD.

This retrospective cohort study included all premature infants with birth weight <1500g from March 1, 2015 to June 30, 2017. Patients were categorized into mild BPD, moderate-to-severe BPD and non BPD groups. Data collected included patient characteristics, C-reactive protein (CRP) tested at six time points, including 1d (2h after birth and before the first feeding), 3d, 7d, 2w, 3w, and 4w after birth, and maternal factors. Ordinal regression analysis was used to identify independent predictors of moderate-to-severe BPD and receiver operating characteristic (ROC) curve was used to evaluate the value of CRP as an early diagnostic marker for moderate-to-severe BPD.

A total of 831 patients were recruited. BPD occurred in 156/831 premature infants with birth weight less than 1500g. Lower birth weight (OR=0.998, 95% CI 0.997-0.999, P=0.004), higher CRP level 3days after birth (OR=1.287, 95% CI 1.195-1.384, P=0.000), and hemodynamically significant patent ductus arteriosus (HsPDA) (OR=12.256, 95% CI 3.766-39.845, P=0.000) were independent risk factors for moderate-to-severe BPD. The area under curve of the CRP level 3days after birth for diagnosing moderate-to-severe BPD was 0.867 (95% CI, 0.823-0.912, P=0.000). The sensitivity was 83.0% and the specificity was 78.3% when the cut-off value was set at 4.105mg/L.

The CRP level 3days after birth may be used as an early diagnostic marker for moderate-to-severe BPD in preterm infants who have the risk factors for BPD with birth weight less than 1500g.

While several radiotracers for imaging redox metabolism have been developed, there are no reports of radiotracers for in vivo imaging of protein oxidation. Here we take the first step towards this goal and describe the synthesis and kinetic properties of a new positron emission tomography (PET) [18F]Fluoro-DCP radiotracer for in vivo imaging of protein sulfenylation. Time course biodistribution and PET/CT studies using xenograft animal models of Head and Neck Squamous Cell Cancer (HNSCC) demonstrate its capability to distinguish between tumors with radiation sensitive and resistant phenotypes consistent with previous reports of decreased protein sulfenylation in clinical specimens of radiation resistant HNSCC. We envision further development of this technology to aid research efforts towards improving diagnosis of patients with radiation resistant tumors.Redox regulation of specific cysteines via oxidoreductases of the thioredoxin family is increasingly being recognized as an important signaling pathway. Here, we demonstrate that the cytosolic isoform of the vertebrate-specific oxidoreductase Glutaredoxin 2 (Grx2c) regulates the redox state of the transcription factor SP-1 and thereby its binding affinity to both the promoter and an enhancer region of the CSPG4 gene encoding chondroitin sulfate proteoglycan nerve/glial antigen 2 (NG2). This leads to an increased number of NG2 glia during in vitro oligodendroglial differentiation and promotes migration of these wound healing cells. On the other hand, we found that the same mechanism also leads to increased invasion of glioma tumor cells. Using in vitro (human cell lines), ex vivo (mouse primary cells), and in vivo models (zebrafish), as well as glioblastoma patient tissue samples we provide experimental data highlighting the Yin and Yang of redox signaling in the central nervous system and the enzymatic Taoism of Grx2c.

Sex offenders often use the internet to communicate with children to facilitate in-person sexual abuse or to create and distribute sexual images of children. Mental healthcare providers are a major source of referrals to child welfare authorities and are well-positioned to identify sexual exploitation.

This study investigated the perceived ability of mental healthcare workers to recognize and respond to concerns about online and in-person sexual exploitation of their pediatric clients.

The authors administered a cross-sectional survey to 209 mental healthcare providers within the public health system of Alberta, Canada.

The survey contained four sections related to sexual exploitation two of which can take place online or in-person (grooming and sexual abuse) and two of which require the internet or a digital device (luring and sexual image distribution). Each section asked whether the mental healthcare provider had experience working with clients affected by these concerns, what barriers they encounter, how confident they are in their abilities and whether they have formal training in a topic.

The vast majority of participants (83%) worked with a client impacted by grooming, luring, sexual abuse or sexual image distribution in the last year. Participants reported more training, more confidence and fewer barriers when identifying and responding to sexual abuse as compared to grooming, luring or sexual image distribution.

There is a need to improve mental health providers understanding of how technology is being utilized to exploit children, so that they can respond effectively to protect their clients.

Nevertheless, few have done so while referencing contextual variables, such as ethnoreligious identity. The current study was designed to examine how ethnoreligious identity affects children's disclosure in forensic interviews beyond the contribution of child characteristics and abuse characteristics. In addition, the moderating role of pre-interview disclosure was examined. An analysis of 1054 forensic interviews conducted in Israel indicated a relationship between a child's age, gender, and abuse characteristics (i.e., perpetrator identity and type of abuse) with the likelihood of disclosure during the forensic interview. The results indicated a relationship between ethnoreligious identity and forensic disclosure. Unexpectedly, Muslim Arab children were more likely to disclose than Jewish children. Predictably, pre-interview disclosure moderated the relationship between abuse characteristics and ethnoreligious identity (among Jews) and forensic disclosure. Conversely, it did not moderate the relationship between child characteristics and disclosure during the forensic interview. The findings demonstrate the importance of a context-informed examination of child abuse disclosure and its potential to advance the development of services adapted to children from diverse communities.

Various parental disciplinary strategies may have different impacts on children's wellbeing. Protective factors, such as school attachment and a growth mindset, may mitigate the influence of harsh discipline on a child's wellbeing.

Based on the strengths-based trauma-informed positive education model, the current study investigated the impacts of three types of parental discipline (corporal punishment, psychological aggression, and nonviolent discipline) on primary school students' wellbeing and examined the moderating roles of school attachment and a growth mindset (both disjunctive and conjunctive moderating effects) in the relationship between parental discipline and student wellbeing.

A sample of 854 primary school students (M=9.40) from eight schools in Hong Kong, China, completed the questionnaire survey at two time points (Time 1 and Time 2), one year apart. Hierarchical regression analysis was applied for data analysis.

Parental psychological aggression at Time 1 (T1) was significantly and negwho are more attached to school and have a growth mindset show higher levels of wellbeing. The study provides further evidence of the role of school attachment in moderating the effect of parental psychological aggression on children's wellbeing in the trauma-informed positive education model.[Bmim]FeCl4, or 1‑butyl‑3-methylimidazolium tetrachloroferrate, is a typical ionic liquid (IL). Its recyclable, magnetic, multicomponent, and solvent-free nature makes it a particularly attractive ionic liquid for use in industrial processes. Despite its widespread use, the potential hazards that [Bmim]FeCl4 might pose to the environment, including productive microorganisms, have not been explored. In this study, the dose-response of [Bmim]FeCl4 in anaerobic digestion (AD) was investigated to assess the potential toxification and biochar-dependent detoxification in microbial communities, including enzymatic activity and molecule docking dynamics. Our results showed that methane production (31.52 mLmax/gVS) was sharply inhibited following [Bmim]FeCl4 treatment. Moreover, increasing the dosage of [Bmim]FeCl4 caused more dissolved organic matter (DOM) to be generated. Interestingly, 0.4 g/L of [Bmim]FeCl4 could stimulate the high activity of microbial hydrolase and ATPase. However, a higher concentration of 2.65e findings were consistent with the short-term activity tests and further verified by functional analysis.The formation of anammox-hydroxyapatite (HAP) coupled granules has been shown to be an approach to efficient nitrogen removal and phosphorus recovery in the anammox EGSB reactor. However, the granulation cycle mechanism of anammox-HAP coupled granules for sustainable regeneration and growth is still not well understood. In this study, the microstructure, chemical composition and microbial structure of a total of six different-sized granules, from 0.25 mm to 2.8 mm, was determined. An SEM-EDS analysis indicated that the small granules (0.5 mm) consisted of a three-layer structure a surface anammox biofilm layer, a middle connection layer, and a HAP mineral inner core. The analysis of elemental composition and microbial structure suggested homogenous granular characteristics regardless of granule size. The dominant microorganisms were anammox bacteria of Candidatus Kuenenia stuttgartiensis and heterotrophic denitrifying bacteria. Based on these results, a granulation cycle mechanism for anammox-HAP coupled granules was proposed for the first time. The growth of the small granules with the simultaneous enlargement of anammox biofilms and HAP cores results in the formation of large granules. PX-12 research buy Large granules regenerate new small granules in a two-step procedure. The first step is the separation of embryo HAP crystals from the mother core via heterogeneous growth, and the second step is the separation of the biofilms due to biodegradation and shear stress.
