BACKGROUND: The professional standards of international medical graduates have been the subject of controversy, but empirical research on this topic has been limited. OBJECTIVES: This report considers whether international medical graduates are at greater risk than US medical graduates for exclusion by the federal government from federally funded programs, such as Medicare and Medicaid. RESEARCH DESIGN: The list of excluded physicians was merged with data regarding 87,729 family and general practice physicians from the American Medical Association Physician Masterfile, 555 of whom were currently excluded. Logistic regression was used to estimate the effect of international medical graduate status on the probability of exclusion, controlling for board-certification status and other physician characteristics. International medical graduates from high-income Organization for Economic Cooperation and Development (OECD) countries are distinguished from other international medical graduates. RESULTS: The adjusted exclusion rates of international medical graduates from OECD countries were similar to that of US medical graduates. Among board-certified physicians, the relative risk of exclusion of non-OECD international medical graduates was 2.19 (P <0.001) compared with US medical graduates. Board certification had an even stronger association: US medical graduates who had never been board certified had a relative risk of 4.12 (P <0.001) compared with board-certified US medical graduates. The never board-certified relative risk was 1.72 (P <0.001) among non-OECD international medical graduates compared with board-certified graduates. Among physicians who had never been board certified, rates of US and international medical graduates did not differ substantially. CONCLUSIONS: Further investigation is needed regarding the causal determinants of exclusion disparities. It is unclear to what extent these disparities may reflect differences in ethical conduct, quality of care, or prejudicial enforcement practices, and the extent to which board certification can causally reduce actions leading to exclusion.

Zhang, Keke; Yang, Yihang; Zhuang, Jianfeng; Guo, Gengyin; Chao, Xin; Zhang, Zhen published the artcile< Intracranial dissemination of glioblastoma multiforme: a case report and literature review.>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is Glioblastoma; case report; intracranial dissemination; no-touch strategy; prognosis; temozolomide.

Intracranial dissemination is rare among patients with glioblastoma multiforme (GBM). Very few GBM patients develop symptoms from intracranial dissemination, as most do not surviving long enough for intracranial dissemination to become clinically evident. Herein, we report a case of GBM in a 39-year-old woman who underwent surgical resection, concomitant chemoradiotherapy, and seven courses of adjuvant chemotherapy with temozolomide. The patient then complained of an instable gait and hearing loss. Imaging studies demonstrated that although the primary intracranial tumors were well-controlled by treatment, contralateral cerebellopontine angle seeding dissemination was present. The patient died 3 months after the diagnosis of seeding dissemination. In light of a previous report and our current case, heightened awareness could promote surgical strategies that minimize the possibility of dissemination, including avoiding ventricular entry or a no-touch strategy.

Wang, Zijing; Yang, Zhipeng; Jiang, Jianjuan; Shi, Zhifeng; Mao, Ying; Qin, Nan; Tao, Tiger H. published the artcile< Silk Microneedle Patch Capable of On-Demand Multidrug Delivery to the Brain for Glioblastoma Treatment>, HPLC of Formula: 112-63-0, the main research area is drug delivery; glioblastoma; microneedle patches; silk proteins.

Glioblastoma (GBM) is the most common and aggressive primary brain tumor. Surgery followed by chemotherapy and radiotherapy remains the standard treatment strategy for GBM patients. However, challenges still exist when surgery is difficult or impossible to remove the tumor completely. Herein, the design, fabrication and application of a heterogenous silk fibroin microneedle (SMN) patch is reported for circumventing the blood-brain barrier and releasing multiple drugs directly to the tumor site for drug combination treatment. The biocompatible and biodegradable SMN patch can dissolve slowly over time, allowing the sustained release of multiple drugs at different doses. Furthermore, it can be triggered remotely to induce rapid drug delivery at a designated stage after implantation. In the GBM mouse models, two clin. relevant chemotherapeutic agents (thrombin and temozolomide) and targeted drug (bevacizumab) are loaded into the SMN patch with individually controlled release profiles. The drugs are spatiotemporally and sequentially delivered for hemostasis, anti-angiogenesis, and apoptosis of tumor cells. Device application is non-toxic and results in decreased tumor volume and increased survival rate in mice. The SMN patch with on-demand multidrug delivery has potential applications for the combined administration of therapeutic drugs for the clin. treatment of brain tumors when other methods are insufficient.

In this study, we combined network pharmacol., chromatog. fingerprinting and multicomponent quant. anal. to evaluate the quality of Moutan Cortex (MC). Specifically, through network pharmacol., we obtained a comprehensive understanding of the active components and pharmacol. activities of MC. In addition, the method of establishing fingerprint and multicomponent quantification by ultra high-performance liquid chromatog. is convenient and comprehensive, and can more fully reflect the overall distribution of various chem. components. Principal component anal. and discriminant least square anal. were used. The results show that MC plays a synergistic role through multiple targets and pathways. The contents of chem. components in MC from different sources were significantly different. Combining network pharmacol. and multicomponent quant. results, gallic acid, benzoyl paeonol, paeonol, Me gallate, benzoic acid and paeonol can be used as quality markers for MC quality control. This study provides a comprehensive and reliable strategy for the quality evaluation of MC and determines its quality indicators to ensure the quality of Chinese herbal medicine.

Concentrations of 2-fluorohistidine (I) [57212-36-9] �0-5 M were bacteriostatic with Escherichia coli, but the inhibition was reversed by the addition of L-histidine [71-00-1]. I also showed antiviral activity in cell cultures. Thyrotropin-releasing-factor (TRF) [24305-27-9] and luteinizing hormone-releasing factor (LHRF) [9034-40-6] were synthesized with I and 4-fluorohistidine [57372-70-0] residues as replacement for the histadine residues; while the 4-fluoro analogs were inactive, those containing I showed 20-30% activity. 4-Fluorohistadine did not show bacterostatic or antiviral activity, but it was a substrate for bacterial histidine decarboxylase [9024-61-7]. Neither 4-fluorourocanic acid [60010-44-8] or 2-fluorourocanic acid [60010-46-0] was a substrate for urocanase [9014-58-8], but the 2-fluoro derivative of urocanic acid was an inhibitor of the enzyme. 2-Fluorohistamine [50581-18-5] had good affinity for H1 histamine receptors in guinea pig ileum.

Bam, Nokwanda E.; Mabunda, Sikhumbuzo A.; Ntsaba, Jafta; Apalata, Teke; Nomatshila, Sibusiso C.; Chitha, Wezile published the artcile< The association between HIV tri-therapy with the development of Type-2 Diabetes Mellitus in a rural South African District: A case-control study>, SDS of cas: 112-63-0, the main research area is HIV infection type2 DM antiretroviral drug stavudine zidovudine lopivavir.

We sought to confirm the association of cARVs with type-2 DM and ascertain the extent of this association in a rural South African setting. Methods: A case-control study of 177 (33.33%) cases with HIV/AIDS and type-2 DM were selected and compared with 354 (66.67%) non-DM HIV/AIDS unmatched controls from a rural district of South Africa’s third most populous province (Eastern Cape). Odds Ratios (OR), together with 95% confidence intervals, were calculated for all the univariable and multivariable logistic analyses. Results: This study found that cARVs significantly increased the occurrence of type-2 DM among HIV patients. Patients on protease inhibitors (PIs) were at least 21 times significantly (p<0.0001) more likely to be diabetic than those on the fixed dose combination (FDC); those on stavudine (D4T) and zidovudine (AZT) were 2.45 times and 9.44 times resp. more likely to be diabetic than those on FDC (p<0.05). The odds of diabetes increased by more than three-folds for those who had been on antiretroviral drugs for more than 6 years (p<0.005). Conclusion: This study has been able to establish the association between cARVs and type-2 DM. It therefore proposes consideration of the usage of AZT, D4T, lopivavir and ritonavir for the treatment of HIV. The study further proposes more prospective research to test these findings further.

Wang, Ruifeng; Zhao, Xiangxin; Yu, Sijia; Chen, Yixuan; Cui, Hengxian; Wu, Tianxiao; Hao, Chenzhou; Zhao, Dongmei; Cheng, Maosheng published the artcile< Discovery of 7H-pyrrolo[2,3-d]pyridine derivatives as potent FAK inhibitors: Design, synthesis, biological evaluation and molecular docking study>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is pyrrolopyrimidine preparation antitumor docking focal adhesion kinase inhibitor SAR; 7H-pyrrolo[2,3-d]pyrimidine; Anticancer; Apoptosis; FAK inhibitor; Migration; Molecular docking.

Focal adhesion kinase (FAK) is an intracellular non-receptor tyrosine kinase responsible for development of various tumor types. Aiming to explore new potent inhibitors, two series of 2,4-disubstituted-7H-pyrrolo[2,3-d]pyrimidine derivatives were designed and synthesized on the base of structure-based design strategy. Biol. evaluation indicated that most of these new compounds could potently inhibit FAK kinase, leading to the promising inhibitors against the proliferation of U-87MG, A-549, and MDA-MB-231 cancer cell lines. Among them, the optimized compound I potently inhibited the enzyme (IC50 = 19.1 nM) and displayed stronger potency than TAE-226 in U-87MG, A-549 and MDA-MB-231 cells, with IC50 values of 0.35, 0.24, and 0.34渭M, resp. Compound I is a multi-target kinase inhibitor. Furthermore, compound I also exhibited relatively less cytotoxicity (IC50 = 3.72渭M) toward a normal human cell line, HK2. According to the flow cytometry and wound healing assay results, compound I effectively induced apoptosis and G0/G1 phase arrest of MDA-MB-231 cells and suppressed the migration of U-87MG, A-549 and MDA-MB-231 cells. The docking study of compound I was performed to elucidate its possible binding modes and to provide a structural basis for the further structural guidance design of FAK inhibitors. Collectively, these data support the further development of compound I as a lead compound for FAK-targeted anticancer drug discovery.

Branco, Luis C.; Afonso, Carlos A. M. published the artcile< Ionic Liquids as a Convenient New Medium for the Catalytic Asymmetric Dihydroxylation of Olefins Using a Recoverable and Reusable Osmium/Ligand>, Quality Control of 112-63-0, the main research area is diol vicinal asym synthesis; alkene Sharpless asym dihydroxylation osmium catalyst ionic liquid solvent; ionic liquid cosolvent osmium catalyzed Sharpless asym dihydroxylation kinetics.

The use of room-temperature ionic liquids (RTILs) in the Sharpless catalytic asym. dihydroxylation (AD) as a cosolvent or replacement of the tert-butanol was studied in detail by screening 11 different RTILs. The AD reaction is faster in 1-n-butyl-3-methylimidazolium hexafluorophosphate [C4mim][PF6] as a cosolvent than in the conventional system of tert-butanol/H2O. For the range of six substrates tested, comparable or even higher yields and enantiomeric excess (ee) were found using [C4mim][PF6] or 1-n-octyl-3-methylimidazolium hexafluorophosphate [C8mim][PF6] compared to the conventional solvent system. Due to high affinity of the catalytic osmium/chiral ligand system to the ionic liquid, the use of ionic liquid/water (biphasic) or ionic liquid/water/tert-butanol (monophasic) solvent systems provides a recoverable, reusable, robust, efficient, and simple system for the AD reaction. On dihydroxylation of 1-hexene using [C4mim][PF6] as RTIL, it was possible to reuse the catalytic system for 9 cycles with only a 5% of yield reduction from the first cycle, allowing an overall yield of 87%, TON = 1566, and with similar ee. Addnl., for each cycle, after extraction of the reaction mixture with di-Et ether, the osmium content in the organic phase (containing the AD product) and in the aqueous phase was in the range of the detection limit (�%, � ppb) and 3-6% of initial amount, resp. In contrast, the ionic liquid phase retained more than 90% of the osmium content of the previous cycle.
