BACKGROUND Little is known about specialist-specific variations in guideline agreement and adoption. OBJECTIVE To assess similarities and differences between allergists and pulmonologists in adherence to cornerstone components of the National Asthma Education and Prevention Program's Third Expert Panel Report (EPR-3). METHODS Self-reported guideline agreement, self-efficacy and adherence were assessed in allergists (n=134) and pulmonologists (n=99) in the 2012 National Asthma Survey of Physicians. Multivariate models were used to assess if physician and practice characteristics explained bivariate associations between specialty and "almost always" adhering to recommendations (i.e., ≥75% of the time). RESULTS Allergists and pulmonologists reported high guideline self-efficacy and moderate guideline agreement. Both groups "almost always" assessed asthma control (66.2%, SE 4.3), assessed school/work asthma triggers (71.3%, SE 3.9), and endorsed inhaled corticosteroids use (95.5%, SE 2.0). Repeated assessment of inhaler technique, use of asthma action/treatment plans and spirometry were lower (39.7%, SE 4.0, 30.6%, SE 3.6, 44.7%, SE 4.1, respectively). Compared to pulmonologists, more allergists almost always performed spirometry (56.6% vs 38.6%, P=.06), asked about nighttime awakening (91.9% vs 76.5%, P=.03) and ED visits (92.2% vs 76.5%, P=0.03), assessed home triggers (70.5% vs 52.6%, P=.06) and performed allergy testing (61.8% vs 21.3%, P less then 0.001). In multivariate analyses, practice-specific characteristics explained differences except for allergy testing. CONCLUSIONS Overall, allergists and pulmonologists adhere to the asthma guidelines with notable exceptions, including asthma action plan use and inhaler technique assessment. Recommendations with low implementation offer opportunities for further exploration and could serve as targets for increasing guideline uptake. BACKGROUND Eosinophilic gastrointestinal diseases (EGID) are defined by marked eosinophilia in the gastrointestinal (GI) tract resulting in a wide variety of GI symptoms. When accompanied by blood hypereosinophilia (HE; AEC≥1500/mm3), EGID can occur as an isolated GI disorder (HES/EGID overlap) or as part of a multisystem hypereosinophilic syndrome (Multisystem HES). OBJECTIVE To describe the gastrointestinal disease of patients categorized as HES/EGID overlap versus those with Multisystem HES. METHODS Consecutively enrolled patients on a natural history protocol to study eosinophilia with biopsy-proven EGID involving the esophagus, stomach, small-bowel and/or colon were evaluated for clinical, histopathologic, and endoscopic features by retrospective chart review. RESULTS Among the 56 patients with EGID and HE, 34 were categorized as HES/EGID overlap and 22 as Multisystem HES. Demographics, GI symptoms and associated comorbidities were similar between the two groups. Multi-segment GI eosinophilia was present in 20/30(67%) patients who underwent tissue sampling of all four GI segments. Tissue eosinophilia in all four GI segments was found in 5/30(17%) patients. Dietary therapy was more common in HES/EGID overlap patients (65% vs. 23%, p=0.0028). Multisystem HES patients were more likely to receive glucocorticoids (100% vs. 79%, p=0.0349) and non-glucocorticoid systemic therapies (77% vs. 38%, p=0.0061). One-third (8/22) of Multisystem HES patients presented with isolated GI symptoms before developing extra-intestinal manifestations at a median of 1 year (range 0.25-15). CONCLUSION There are striking clinical similarities between Multisystem HES and HES/EGID overlap patients, despite differing treatment approaches. Moreover, Multisystem HES can present with isolated GI involvement. Larger prospective studies are needed to confirm these findings. The Neuropilin (Nrp) family of cell surface receptors have key physiological and pathological functions. Nrp2 is of particular interest due to its involvement in tumor metastasis. CTP-656 purchase Currently, peptide and small molecule inhibitors that target Nrp utilize arginine-based molecules which have limitations due to high inherent flexibility and issues related to stability. Further, there are no known small molecule inhibitors specific for Nrp2. Recent molecular insights identify a key ligand binding region in the b1 domain of Nrp2 responsible for binding the C-terminus of its cognate ligand VEGF-C. Based on this, we report the discovery of a novel benzamidine-based inhibitor that functions through competitive inhibition of VEGF-C binding to Nrp2. Further, we have explored inhibitor functionality and selectivity by defining its structure-activity relationship (SAR) providing valuable insights on this benzamidine-based family of Nrp2 inhibitors. This study provides the basis for further development of a potent and specific small molecule inhibitor that competitively targets pathological Nrp2 function. Ganoderma resinaceum is a multi-purpose herbal medicine that is homologous to functional food that has long been used for enhancing health and treating chronic hepatopathy in Traditional Chinese Medicine. In a search program to discover the key bioactive composition of G. resinaceum, sixteen new lanostane-type triterpenoids (1-16), and twenty known analogues (17-36) were isolated from the fruiting bodies of G. resinaceum. Spectroscopic analyses and X-ray crystallography were used to determine the new structures. Furthermore, the spectroscopic properties of 15β-hydroxy-4,4,14α- trimethyl-3,7,11,20-tetraoxo-5α-pregn-8-ene (15) and 15α-hydroxy-4,4,14α-trimethyl- 3,7,11,20-tetraoxo-5α-pregn-8-ene (34) indicated a potential structural misassignment of their analogues, lucidone E and lucidone H, reported previously. To probe this hypothesis, ROESY experiments and single-crystal X-ray diffraction analysis were conducted. These results undoubtedly reassigned the structure of lucidone E and lucidone H. Biological evaluation of the selected compounds disclosed that compounds 3, 4, 7/21, 11, 12, 13/14, 17, 18, 24/25, 27, 30, 31, and 35 had significant hepatoprotective activities, due to their remarkable in vitro inhibitory activities against the increase of ALT and AST levels in HepG2 cells induced by H2O2. Phosphatidylinositol 3-kinase (PI3K) is one of the most attractive therapeutic targets for cancer treatment. In this study, a series of new 2-arylthio- and 2-arylamino-1H-benzo[d]imidazole derivatives of dehydroabietic acid were designed, synthesized and characterized by 1H NMR, 13C NMR, IR and MS spectra analyses. In the in vitro anticancer assay, some title compounds showed significant inhibitory activities against four cancer cell lines (HCT-116, MCF-7, HeLa and HepG2). Among them, compound 9g exhibited the most potent activity with IC50 values of 0.18 ± 0.03, 0.43 ± 0.05, 0.71 ± 0.08 and 0.63 ± 0.09 μM against four cancer cell lines, and considerably lower cytotoxicity to human gastric mucosal cell line Ges-1 (IC50 21.95 ± 0.73 μM). Besides, compound 9g displayed a certain selective activity to PI3Kα (IC50 = 0.012 ± 0.002 μM) over PI3Kβ, γ and δ, and meanwhile, it can remarkably decrease the expression level of p-Akt (Ser473). In addition, compound 9g could increase intracellular reactive oxygen species level, decrease mitochondrial membrane potential, upregulate Bax and cleaved caspase-3/9 levels, downregulate Bcl-2 level and thus induce the apoptosis of HCT-116 cells in a dose-dependent manner. The results suggested that compound 9g could be considered as a promising PI3Kα inhibitor. This manuscript has reported different mutations of β-catenin gene in gallbladder cancer patients which affect GSK-3β phosphorylation site. PURPOSE Gallbladder carcinoma (GBC) is a relatively rare and fatal cancer with poor prognosis. The molecular mechanism of gallbladder carcinogenesis is still not clear. Wnt signaling pathway is a highly conserved pathway that regulates proliferation, differentiation, migration, genetic stability, apoptosis, and stem cell renewal. β-catenin plays major role in Wnt signaling and aberrations in β-catenin has found to be involved in several cancers pathogenesis. This study was carried out to document the mutations of β-catenin gene in gallbladder cancer and to evaluate its possible role in gallbladder carcinogenesis. METHODS PCR-SSCP (Single Stranded Conformation Polymorphism) for ctnnb1 was performed in 50 patients each of gallbladder cancer, cholelithiasis and 50 healthy controls. Samples that showed variation in banding pattern were sequenced. RESULTS Variation in banding pattern was observed in 9 (18%) samples of GBC, 4 (8%) of cholelithiasis and 2 (4%) of control. Sequencing analysis showed 9 novel mutations of ctnnb1 in exon 3 in 18% of gallbladder cancer (χ2 = 5.778; p less then 0.05). Six point mutations, 1 deletion and 1 insertion mutation were found in 9 cases of gallbladder cancer. All point mutations were mis-sense mutation that affected highly conserved serine or threonine region that is important for GSK-3β phosphorylation. CONCLUSION Findings of the study suggests that high frequency of non synonymous mutations of β-catenin gene (ctnnb1) occurs in patients with gallbladder cancer. As these mutations mainly effect GSK 3β phosphorylation, it may be concluded that this might be an important step in gallbladder carcinogenesis. These β-catenin mutations lead to Wnt pathway activation and appear to have a role in progression from inflammation to cancer in gallbladder. Myocardial infarction (MI) injury is a highly lethal syndrome that has, until recently, suffered from a lack of clinically efficient targeted therapeutics. The cardiac troponin I interacting kinase (TNNI3K) exacerbates ischemia-reperfusion (IR) injury via oxidative stress, thereby promoting cardiomyocyte death. In this current study, we designed and synthesized 35 novel TNNI3K inhibitors with a pyrido[4,5]thieno[2,3-d] pyrimidine scaffold. In vitro results indicated that some of the inhibitors exhibited sub-micromolar TNNI3K inhibitory capacity and good kinase selectivity, as well as cytoprotective activity, in an oxygen-glucose deprivation (OGD) injury cardiomyocyte model. Furthermore, investigation of the mechanism of the representative derivative compound 6o suggested it suppresses pyroptosis and apoptosis in cardiomyocytes by interfering with p38MAPK activation, which was further confirmed in a murine myocardial infarction injury model. In vivo results indicate that compound 6o can markedly reduce myocardial infarction size and alleviate cardiac tissue damage in rats. In brief, our results provide the basis for further development of novel TNNI3K inhibitors for targeted MI therapy. Mycoplasma genitalium is one of the sexually transmitted pathogens that cause significant morbidity in the host. The development of effective therapeutic procedures is urgently needed to counter the multi-drug resistant events imposed by this pathogen. In the current version of M. genitalium G37 genome, 512 open reading frames have been identified. The function of 91 proteins encoded by M. genitalium genes was found to be hypothetical and these proteins were termed hypothetical proteins (HPs). This study aims to carry out functional characterization of HPs by a systems biology approach. Functional assignments of 61 HPs were made with high confidence. They belong to different functional groups, such as DNA-binding proteins, helicases and transporters. Approximately 26% of HPs were identified as transporters, suggesting that M. genitalium is likely to rely on the exogenous nutrient supply for survival. A group of 20 proteins was predicted to be virulence factors, indicating the pathogenic characteristics of M. genitalium.
