A Practical and Modular Method for Direct C-H Functionalization of the BODIPY Core via Thianthrenium Salts.

Direct structural modification of small-molecule fluorophores represents a straightforward and appealing strategy for accessing new fluorescent dyes with desired functionalities. We report herein a general and efficient visible-light-mediated method for the direct C-H functionalization of BODIPY, an important fluorescent chromophore, using readily accessible and bench-stable aryl and alkenylthianthrenium salts. This practical approach operates at room temperature with extraordinary site-selectivity, providing a step-economical means to construct various valuable aryl- and alkenyl-substituted BODIPY dyes. Remarkably, this protocol encompasses a broad substrate scope and excellent functional-group tolerance, and allows for the modular synthesis of sophisticated symmetrical and asymmetrical disubstituted BODIPYs by simply employing different combinations of thianthrenium salts. Moreover, the late-stage BODIPY modification of complex drug molecules further highlights the potential of this novel methodology in the synthesis of fluorophore-drug conjugates.

Enhancing Enzyme Activity and Thermostability of Bacillus amyloliquefaciens Chitosanase BaCsn46A Through Saturation Mutagenesis at Ser196.

Chitosanase plays an important role in chitooligosaccharides (COS) production. We found that the chitosanase (BaCsn46A) of Bacillus amyloliquefacien was a good candidate for chitosan hydrolysis of COS. In order to further improve the enzyme properties of BaCsn46A, the S196 located near the active center was found to be a critical site impacts on enzyme properties by sequence alignment analysis. Herein, saturation mutation was carried out to study role of 196 site on BaCsn46A catalytic function. Compared with WT, the specific enzyme activity of S196A increased by 118.79%, and the thermostability of S196A was much higher than WT. In addition, we found that the enzyme activity of S196P was 2.41% of that of WT, indicating that the type of amino acid in 196 site could significant affect the catalytic activity and thermostability of BaCsn46A. After molecular docking analysis we found that the increase in hydrogen bonds and decrease in unfavorable bonds interacting with the substrate were the main reason for the change of enzyme properties which is valuable for future studies on Bacillus species chitosanase.

Comparative study on inhibitory effects of ferulic acid and p-coumaric acid on Salmonella Enteritidis biofilm formation.

Biofilm cells exhibit higher resistance than their planktonic counterparts to commonly used disinfectants in food industry. Phenolic acids are promising substitute offering less selective pressure than traditional antibiotics. This study aims to evaluate the inhibitory effects of ferulic acid (FA) and p-coumaric acid (p-CA) on Salmonella Enteritidis biofilm formation and explore the underlying inhibitory mechanisms. The minimal inhibitory concentration (MIC) of FA and p-CA were 1.0 and 0.5 mg/ml, respectively. The sub-inhibitory concentration (1/8 MIC) significantly decreased biofilm formation without growth inhibitory effects. The biomass and extracellular polymeric substances (EPS) of S. Enteritidis biofilm as well as the bacterial swimming and chemotaxis abilities were significantly decreased when exposed to sub-MIC concentrations of FA and p-CA. These two phenolic acids showed high affinity to proteins involved in flagella motility and repressed the S. Enteritidis biofilm formation-related gene expressions. Furthermore, these two phenolic acids maintained high antibiofilm efficiency in simulated food processing conditions. This study provided valuable information of multiple phenotypic and molecular responses of S. Enteritidis to these two phenolic acids.

Rapid response to secukinumab in a 5-year-old with deficiency of the interleukin-36 receptor antagonist (DITRA) with severe scalp and nail involvement.

Deficiency of the interleukin-36 receptor antagonist (DITRA) is an autosomal recessive disease caused by mutations of the IL36RN gene. DITRA is characterized by acute generalized pustular psoriasis (GPP), fever, systemic inflammation, and leukocytosis. We report the case of a 5-year-old girl with severe scalp and nail involvement with a rapid response to secukinumab.

A novel SOCS5/miR-18/miR-25 axis promotes tumorigenesis in liver cancer.

The role of miRNAs with tumor suppressive activity in liver cancer has been well studied. However, little is known about potential oncomiRs in HCC. In our study, we conducted a systematic evaluation of candidate oncomiRs and found that upregulation of miR-18a and miR-25 in HCC was associated with poor patient survival and promoted proliferation in HCC cell lines. These two miRNAs belong to the polycistronic paralogous miR-17-92 and miR-25-106b clusters respectively. Although the members of both clusters are often upregulated in HCC, the contribution of individual miRNAs in these clusters to HCC tumorigenesis is not fully understood. We validated SOCS5 as a bona fide target of both miRNAs, and established, for the first time, the tumor suppressive role of SOCS5 in liver cancer. We further investigated the mechanism by which SOCS5 contributes to tumorigenesis, demonstrated that this SOCS5/miR-18a/miR-25 axis regulates the tumor suppressor TSC1 and downstream mTOR signaling, and highlighted the potential therapeutic use of miR-18a and miR-25 inhibition in restoring SOCS5 levels in HCC.

Terahertz dispersion using multi-depth phase modulation grating.

We present a multi-depth phase modulation grating (MPMG) in the terahertz range making real-time multichannel Fourier-transform spectroscopy available in a stationary manner. The calculation of the Fraunhofer diffraction field distribution and diffraction efficiency of an MPMG indicates that the zeroth-order diffraction light of an MPMG carries phase information and its diffraction intensity is modulated by the groove depth. A good agreement is found between the measurements of the 0th- and ±1st-order diffraction efficiency at 0.5 and 0.34 THz and the simulation. The frequencies of the terahertz source retrieved from the zeroth-order diffraction intensity at 0.5, 0.4, and 0.34 THz are identical to the actual frequencies.

Resveratrol ameliorates gouty inflammation via upregulation of sirtuin 1 to promote autophagy in gout patients.

BACKGROUND: Resveratrol exerts an anti-inflammatory effect on collagen-induced arthritis and osteoarthritis in rats via activation of sirtuin 1 (SIRT1). Autophagy can be induced by resveratrol and leads to amelioration of interleukin-1 beta (IL-1ß) release in vitro. We aimed to determine the anti-inflammatory mechanisms of resveratrol in patients with gout. METHODS: Blood samples were obtained from patients with acute gout, intercritical gout (IG) and healthy controls (HC). The mRNA and protein levels of SIRT1 and nuclear factor-kappa B (NF-kB) p65 were determined in peripheral blood mononuclear cells (PBMCs) lysate from these patients. In the in vitro experiment, SIRT1, autophagy-related genes (beclin-1 and microtubule-associated protein 1 light-chain 3) and key genes involved in the gouty inflammatory pathway, including NF-κB p65, NLR family pyrin domain containing 3 (NLRP3), caspase-1 and IL-1ß, were determined in PBMCs lysate or plasma from IG patients exposed to monosodium urate (MSU) crystals with or without resveratrol. RESULTS: The mRNA and protein levels of SIRT1 were downregulated in PBMCs from gout patients in comparison with HC. In the in vitro experiment, the protein levels of SIRT1 were downregulated in PBMCs from IG patients exposed to MSU crystals and were restored by resveratrol in a dose-dependent manner. Furthermore, high doses of resveratrol ameliorated the release of the inflammatory cytokine IL-1ß. In addition, the mRNA levels of NLRP3 and NF-κB p65 were regulated by resveratrol, but caspase-1 and IL-1ß were not. Furthermore, resveratrol promoted MSU-induced autophagy in PBMCs from patients with gout. CONCLUSION: These findings suggest that resveratrol ameliorates gouty inflammation via upregulation of SIRT1 to promote autophagy in patients with gout.

Comparison of geometrical uncertainties in the radiotherapy for various treatment sites with two different immobilization marking methods.

OBJECTIVE: The skin marking method (SMM) and bow-form-ruler marking method (BFRM) are two commonly used patient marking methods in mainland China. This study aims to evaluate SMM and BFRM by comparing the inter-fraction setup errors from using these two methods together with vacuum cushion immobilization in patients underwent radiotherapy for different treatment sites. MATERIALS AND METHODS: Eighteen patients diagnosed with pelvic, abdominal and thoracic malignant tumors (with 6 patients per treatment site) were enrolled in this prospective study. All patients were immobilized with vacuum cushion. Each patient was marked by both SMM and BFRM before computed tomography (CT) simulation. Target location was verified by cone beam CT images with displacements assessed prior to each sampled treatment session. The localization errors in three translational and three rotational directions were recorded and analyzed. RESULTS: Images from 108 fractions in 18 patients produced 324 translational and 324 rotational comparisons for SMM and BFRM. The setup errors of all treatment sites showed no difference in two marking methods in any directions (p > 0.05). In subgroups of treatment site analysis, SMM significantly lessened the lateral and yaw setup errors compared to BFRM in the pelvic sites (0.39±1.85 mm vs -1.28±1.13 mm, p < 0.01 and -0.19±0.59° vs -0.61±0.59°, p < 0.05). However, in the abdominal subgroup, BFRM was superior to SMM for reduced vertical errors (0.17±2.73 mm vs 2.28±3.16 mm, p < 0.05). For the underweight or obese patients (with Body Mass Index, BMI < 18.5 or BMI≥24), SMM resulted in less yaw errors compared to BFRM (-0.05±0.38° vs -0.43±0.48°, p < 0.05). No significant difference between SMM and BFRM in setup errors of normal weighted patients (18.5≤BMI < 24) was observed for all three studied treatment sites. CONCLUSIONS: This study shows no significant difference in patient setup errors for various treatment sites between SMM and BFRM in general. SMM may be suitable for the pelvic tumor and patients with BMI < 18.5 or BMI≥24, while BFRM is recommended for the abdominal tumor sites.

Effects of small interfering RNA targeting TLR4 on expressions of adipocytokines in obstructive sleep apnea hyponea syndrome with hypertension in a rat model.

We explored the effects of RNA interference-mediated silencing of TLR4 gene on expressions of adipocytokines in obstructive sleep apnea hyponea syndrome (OSAS) with hypertension in a rat model. Systolic blood pressure of caudal artery and physiological changes were observed when establishing rat models of OSAS with hypertension. Mature rat adipocytes were induced from separated and cultured primary rat adipocytes. To transfect rat mature adipocytes, TLR4 siRNA group and negative control (NC) siRNA group were established. Expressions of TLR4 mRNA of adipocytes were examined after silenced by siRNA by quantitative real-time polymerase chain reaction (qRT-PCR). By enzyme-linked immunosorbent assay (ELISA), expressions of inflammatory cytokines, and adipocytokines of adipocytes were detected. Blood pressure in rat caudal artery was higher in the intermittent hypoxia group than that of the blank control group by 29.87 mmHg, and cardiocytes in the former group showed physiological changes, which indicated successful establishment of rat models of OSAS with hypertension. Red particles could be seen in mature rat adipocytes when stained with Oil Red O. Transfection of TLR4 mRNA was significantly suppressed in the TLR4 siRNA group, which didn't happen in the untransfected control group. Rats in the TLR4 siRNA group had significantly reduced expressions of such inflammatory cytokines as interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) and such adipocytokines as visfatin, adiponectin (ADN), and leptin than those in the untransfected control group. RNA interference-mediated silencing of TLR4 gene could regulate occurrence and development of OSAS with hypertension in rats by downregulating expressions of adipocytokines.

Clinical Drug Response Prediction by Using a Lq Penalized Network-Constrained Logistic Regression Method.

BACKGROUND/AIMS: One of the most important impacts of personalized medicine is the connection between patients' genotypes and their drug responses. Despite a series of studies exploring this relationship, the predictive ability of such analyses still needs to be strengthened. METHODS: Here we present the Lq penalized network-constrained logistic regression (Lq-NLR) method to meet this need, in which the predictors are integrated into the gene expression data and biological network knowledge and are combined with a more aggressive penalty function. Response prediction models for two cancer targeting drugs (erlotinib and sorafenib) were developed from gene expression data and IC50 values from a large panel of cancer cell lines by utilizing the proposed approach. Then the drug responders were tested with the baseline tumor gene expression data, yielding an in vivo drug sensitivity prediction. RESULTS: These results demonstrated the high effectiveness of this approach. One of the best results achieved by our method was a correlation of 0.841 between the cell line in vitro drug response and patient's in vivo drug response. We then applied these two drug prediction models to develop a personalized medicine approach in which the subsequent treatment depends on each patient's gene-expression profile. CONCLUSION: The proposed method is much better than the existing approach and can capture a more accurate reflection of the relationship between genotypes and phenotypes.

Soluble Egg Antigen Activates M2 Macrophages via the STAT6 and PI3K Pathways, and Schistosoma Japonicum Alternatively Activates Macrophage Polarization to Improve the Survival Rate of Septic Mice.

Sepsis is one of the most challenging health problems worldwide. Our previous study showed that chronic schistosoma japonica (SJ) infection might increase serum anti-inflammatory factors to play a protective role, thus improving the survival rate of septic mice. Further research revealed that SJ infection promoted J774A.1 macrophage differentiation into M2 macrophages; suppressed LPS-induced activation of M1 macrophages; up-regulated CD163, IL-10, and TGF-ß1 expression; inhibited TNF-α and iNOS expression; and blocked the effect of LPS-promoted TNF-α and iNOS expression. Furthermore, adoptive transfer of ex vivo programed M2 macrophages significantly increased the survival rate of septic mice. In vitro studies suggested that soluble egg antigen (SEA) from SJ played the same role as worm infection but had no impact on M1 macrophages. SEA reduced LPS-induced TNF-α and iNOS expression, decreased the inhibitory effect of LPS on IL-10 and TGF-ß1 expression, increased STAT6 phosphorylation, and up-regulated PI3K and Akt expression but inhibited SOCS1 expression. When PI3K inhibitors were added, SEA-induced expression of CD163, IL-10, and arg1 might be reduced. Therefore, worm infection has a protective effect in septic mice in which SEA may play a key role via the STAT6 and PI3K pathways. This finding may provide a favorable solution for the treatment of sepsis, especially early cases. J. Cell. Biochem. 118: 4230-4239, 2017. © 2017 Wiley Periodicals, Inc.

Biodegradation of 5-chloro-2-picolinic acid by novel identified co-metabolizing degrader Achromobacter sp. f1.

Several bacteria have been isolated to degrade 4-chloronitrobenzene. Degradation of 4-chloronitrobenzene by Cupriavidus sp. D4 produces 5-chloro-2-picolinic acid as a dead-end by-product, a potential pollutant. To date, no bacterium that degrades 5-chloro-2-picolinic acid has been reported. Strain f1, isolated from a soil polluted by 4-chloronitrobenzene, was able to co-metabolize 5-chloro-2-picolinic acid in the presence of ethanol or other appropriate carbon sources. The strain was identified as Achromobacter sp. based on its physiological, biochemical characteristics, and 16S rRNA gene sequence analysis. The organism completely degraded 50, 100 and 200 mg L-1 of 5-chloro-2-picolinic acid within 48, 60, and 72 h, respectively. During the degradation of 5-chloro-2-picolinic acid, Cl- was released. The initial metabolic product of 5-chloro-2-picolinic acid was identified as 6-hydroxy-5-chloro-2-picolinic acid by LC-MS and NMR. Using a mixed culture of Achromobacter sp. f1 and Cupriavidus sp. D4 for degradation of 4-chloronitrobenzen, 5-chloro-2-picolinic acid did not accumulate. Results infer that Achromobacter sp. f1 can be used for complete biodegradation of 4-chloronitrobenzene in remedial applications.

Pulmonary rehabilitation after lung transplantation with severe complications: A case report.

This case study describes a 59-year-old male with a body mass index of 14.4 kg/m2 and a diagnosis of interstitial lung disease, pneumoconiosis, and severe pulmonary hypertension who received a bilateral lung transplant in a hospital in mainland China. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) was initiated before the lung transplant; in addition, an emergency thoracotomy was performed three hours afterwards due to uncontrolled bleeding. VA-ECMO was weaned 34 hours later, but weaning from the ventilator failed multiple times due to bilateral pneumothorax, weak neuromuscular drive, and muscle strength. A full, personalized rehabilitation program was initiated with the help of a respiratory therapy team and the physician, drawing on the American Thoracic Society/European Respiratory Society Statement on Pulmonary Rehabilitation. This included nutrition support, draining air from the chest pleural cavity, aggressive bronchial-hygiene therapy, a weaning plan, breathing and physical exercises, and psychological support. Eighty-one days after the tracheotomy, the patient was successfully weaned, decannulated, and discharged. A careful, ongoing evaluation and a personalized program assisted with weaning this difficult patient.

[Effect of Modified Danggui Yinzi on Delayed Allergy in Model Mice with Qi-Blood Deficiency Syndrome].

OBJECTIVE: To explore the effect of Danggui Yinzi (DY) on delayed allergy in model mice with qi-blood deficiency syndrome (QBDS). METHODS: QBDS model was established in 48 Kuming mice of SPF grade by using reserpine and acetophenone hydrazine. Forty of them were then randomly divided into the model group, the loratadine group, the high dose DY group, the middle dose DY group, and the low dose DY group, 8 in each group. Another 8 in line with the same standard were recruited as a blank group. Mice in high, middle, and low dose DY groups were administered with DY concentrated solution at 60, 30, 15 g/kg by gastrogavage. Mice in the loratadine group were administered with loratadine solution at 1.66 mg/kg by gastrogavage. Equal volume of normal saline was administered to mice in the model group and the blank group by gastrogavage. All medication was given once per day for 1 successive week. Except those in the blank group, the rest mice were evenly smeared with 1% DNCB solution on the abdomen. Five days after skin allergy, 1% DNCB solution was smeared to right ear of all mice to stimulate allergic reaction. Mice in the blank group were smeared in the same way without allergenic reaction. The auricle swelling and the inhibition ratio were determined at 24 h after attack. Blood was collected from orbit and serum IgE level detected using double-antibody sandwich ELISA. RESULTS: Compared with the blank group, auricle swelling obviously increased and serum IgE level was obviously elevated in the model group (P < 0.01). Compared with the model group, auricle swelling obviously decreased and serum IgE level was obviously reduced in the 3 dose DY groups (P < 0.05, P < 0.01). Meanwhile, the auricle swelling degree was superior in high and middle dose DY groups to that in the loratadine group (P < 0.05). The inhibition ratio of auricle swelling was sequenced from high to low as 67.3% in the high dose DY group, 56.0% in the middle dose DY group, 48.1% in the low dose DY group, 47.3% in the loratadine group. CONCLUSIONS: DY could inhibit auricle swelling and lower serum IgE level. It also could inhibit delayed allergic reaction in model mice with QBDS to some extent.

Infrared and visible image fusion with spectral graph wavelet transform.

Infrared and visible image fusion technique is a popular topic in image analysis because it can integrate complementary information and obtain reliable and accurate description of scenes. Multiscale transform theory as a signal representation method is widely used in image fusion. In this paper, a novel infrared and visible image fusion method is proposed based on spectral graph wavelet transform (SGWT) and bilateral filter. The main novelty of this study is that SGWT is used for image fusion. On the one hand, source images are decomposed by SGWT in its transform domain. The proposed approach not only effectively preserves the details of different source images, but also excellently represents the irregular areas of the source images. On the other hand, a novel weighted average method based on bilateral filter is proposed to fuse low- and high-frequency subbands by taking advantage of spatial consistency of natural images. Experimental results demonstrate that the proposed method outperforms seven recently proposed image fusion methods in terms of both visual effect and objective evaluation metrics.

Micrometam C Protects against Oxidative Stress in Inflammation Models in Zebrafish and RAW264.7 Macrophages.

Micrometam C is a core of novel marine compound isolated from the mangrove associates Micromelum falcatum. In this study, we investigated the protective effects of micrometam C in inflammation models in the transgenic zebrafish line Tg (corola: eGFP) and RAW264.7 macrophages. We found that micrometam C significantly suppressed the migration of immune cells in tail-cutting-induced inflammation in transgenic zebrafish and reduced lipopolysaccharide (LPS)-induced reactive oxygen species (ROS) in both zebrafish and macrophages. In addition, micrometam C also restored LPS-induced reduction of endogenous antioxidants, such as catalase (CAT), glutathione (GSH) and superoxide dismutase (SOD). The protective effects of micrometam C were in parallel to its inhibition of NADPH oxidase and nuclear factor-kappa-binding (NF-κB) activity. Thus, the present results demonstrate that micrometam C protects against LPS-induced inflammation possibly through its antioxidant property.

[Changes in expression of PYCARD gene and its transcript variant mRNA in peripheral blood mononuclear cells of patients with primary gout].

OBJECTIVE: To determine the expression level and role of PYCARD [PYRIN-PAAD-DAPIN domain (PYD) and a C-terminal caspase recruitment domain (CARD), PYCARD] gene and its transcript variant mRNA in peripheral blood mononuclear cells (PBMCs) of patients with primary gout (PG). METHODS: PYCARD gene and its transcript variant mRNA were measured using reverse transcription-polymerase chain reaction (RT-PCR) in PBMCs. The expression of PYCARD gene and PYCARD-1,-2 mRNA in PBMCs was compared between the patients with acute phase PG (APPG) (n=44), non-acute phase PG (NAPPG) (n= 51) and healthy controls (HC) (n=87). PYCARD and NF-kappaB (p105/p50) protein expressions were measured using Western blot in the PBMCs of participants in the PG and HC groups. Routine blood tests and blood uric acid test were undertaken in all participants. Differences in the indicators were examined among the three groups. Correlations between the expression of PYCARD gene and PYCARD-1,-2 mRNA and other indicators were analyzed. RESULTS: The expression level of PYCARD gene, PYCARD-1,-2 mRNA was significantly higher in the APPG and NAPPG group than in the HC group (P<0.01). The NAPPG group had significantly higher levels of PYCARD gene transcript variant 2x mRNA and 2y mRNA in the HC and APPG groups (P<0.05). The expression of PYCARD and NF-kappaB (p105/p50) protein was significantly higher in the PG group compared with the HC group [(4.900 +/- 1.324) vs. (3.975 +/- 0.210) and (0.263 +/- 0.106) vs. (0.127 +/- 0.008), respectively P<0.05]. The expression level of PYCARD-2 mRNA and granulocyte were positively correlated in the NAPPG group. CONCLUSION: Abnormal expression of PYCARD gene and its transcript variant and PYCARD protein in PG patients suggests that PYCARD gene and its transcript variant may play an important role in regulating the inflammatory response of PG patients.

Diastereomeric aziridine carbinol catalyzed enantioselective arylation reaction: toward the asymmetric synthesis of both enantiomers of chiral 3-aryl phthalide.

The diastereomeric aziridine carbinols are applied, respectively, as efficient chiral ligand in the catalysis of asymmetric arylation and sequential arylation-lactonization cascade. The two diastereomers, which are facilely synthesized from the same chiral source, function as pseudo enantiomers in arylation of aromatic aldehydes providing the different enantiomers of the diarylmethanols with almost the same excellent enantioselectivities. The arylation method is also carried out in tandem with lactonization process to afford a concise synthetic approach to both enantiomers of optically active 3-aryl phthalide.

Changes in toll-like receptor (TLR)4-NFκB-IL1ß signaling in male gout patients might be involved in the pathogenesis of primary gouty arthritis.

We undertook this study to determine whether the altered toll-like receptor (TLR)4-nuclear factor κB (NFκB)-interleukin1ß (IL1ß) signaling in peripheral blood of gout patients could provide insights into the pathogenesis of primary gouty arthritis (GA). TLR4 mRNA, TLR4 and NFκBp65 proteins expression and IL1ß production were measured in 52 acute GA (AGA) and 34 non-acute GA (NAGA) male patients and 78 male healthy subjects (HC). NFκBp65 transcriptional activity and IL1ß production were measured after TLR4 inhibition with anti-TLR4 antibody in peripheral whole blood from 13 AGA patients. The TLR4, NFκBp65 and IL1ß expression was significantly increased in the AGA group than those in the NAGA or HC group (P < 0.05, respectively), also the levels were higher in the NAGA group comparing with those in the HC group (P < 0.05, respectively). Furthermore, moderate positive correlations were observed between concentration of uric acid and the TLR4 mRNA level, serum IL1ß production (r = 0.649, 0.616), and strong positive correlation was observed between TLR4 mRNA level and serum IL1ß (r = 0.848) in 52 AGA patients. On the other hand, NFκBp65 level and IL1ß production were dramatically reduced after TLR4 blockade with anti-TLR4 antibody in peripheral blood from the AGA patients (P < 0.05, respectively). TLR4-NFκB-IL1ß signaling might play a crucial role in the development of acute inflammation in primary gout patients.
