Michael addition of 3-tert-butylpyrazole (1) or 3,5-dimethylpyrazole (2) to acrylamide afforded the pyrazolylpropanamide-type ligands 3-(3-tert-pyrazol-1-yl)propanamide (3, = (t)BuPPA) and 3-(3,5-dimethylpyrazol-1-yl)propanamide (4, = Me(2)PPA), respectively, in high isolated yields (3: 80%, 4: 76%). Reactions of 4 with selected first-row transition-metal chlorides (MnCl2 center dot 4H(2)O, CoCl2 center dot 6H(2)O, ZnCl2, CuCl2 center dot 2H(2)O) afforded the new complexes MnCl2(Me(2)PPA)(2) (5), [MCl2(Me(2)PPA)](2) (M = Co (6), Zn (7)), and CuCl2(Me(2)PPA)(2)center dot 2H(2)O (8). Ligand 3 and all four new complexes 58 have been structurally characterized though single-crystal X-ray diffraction. Surprisingly, the crystal structure determinations revealed three different coordination modes for the pyrazole-based ligand in these complexes. Seven-membered kappa N,kappa O-chelate rings are present in the manganese(II) complex 5. In contrast, kappa N: kappa O-bridging coordination of Me(2)PPA in compounds 6 and 7 leads to formation of dimers comprising 14-membered ring systems. Furthermore, unusual kappa N-monodentate coordination of Me2PPA has been found in the structure of the hydrated copper(II) complex Cu(Me(2)PPA)(2)Cl-2 center dot 2H(2)O (8). In the crystalline state, all four complexes 58 form one- or two-dimensional supramolecular structures assembled through different types of hydrogen bonding. (C) 2019 Elsevier Ltd.

Deregulation of the transcriptional repressor BCL6 enables tumorigenesis of germinal center B-cells, and hence BCL6 has been proposed as a therapeutic target for the treatment of diffuse large B-cell lymphoma (DLBCL). Herein we report the discovery of a series of benzimidazolone inhibitors of the protein-protein interaction between BCL6 and its co-repressors. A subset of these inhibitors were found to cause rapid degradation of BCL6, and optimization of pharmacokinetic properties led to the discovery of 5-((5-chloro-2-((3R,SS)-4,4-difluoro-3,5-dimethylpiperi din-1-yl) pyrimidin-4-yl) amino)-3-(3-hydroxy-3-methylbutyl)-1-methyl-1,3-dihydro-2H-benzo[d]imidazol-2-one (CCT369260), which reduces BCL6 levels in a lymphoma xenograft mouse model following oral dosing.

Importance: treatment of dementia in individuals with comorbidities is complex, leading to potentially inappropriate prescribing (PIP). The impact of PIP in this population is unknown. Objective: to estimate the rate of PIP and its effect on adverse health outcomes (AHO). Design: retrospective cohort. Setting: primary care electronic health records linked to hospital discharge data from England. Subjects: 11,175 individuals with dementia aged over 65 years in 2016 and 43,463 age- and sex-matched controls. Methods: Screening Tool of Older Persons’ Prescriptions V2 defined PIP. Logistic regression tested associations with comorbidities at baseline, and survival analyses risk of incident AHO, adjusted for age, gender, deprivation and 14 comorbidities. Results: the dementia group had increased risk of PIP (73% prevalence; odds ratio [OR]: 1.92; confidence interval [CI]: 83-103%; P < 0.01) after adjusting for comorbidities. Most frequent PIP criteria were related to anti-cholinergic drugs and therapeutic duplication. Risk of PIP was higher in patients also diagnosed with coronary-heart disease (odds OR: 2.17; CI: 1.91-2.46; P < 0.01), severe mental illness (OR: 2.09; CI: 1.62-2.70; P < 0.01); and depression (OR: 1.81; CI: 1.62-2.01; P < 0.01). During follow-up (1 year), PIP was associated with increased all-cause mortality (hazard ratio: 1.14; CI: 1.021.26; P < 0.02), skin ulcer and pressure sores (hazard ratio: 1.66; CI: 1.12-2.46; P< 0.01), falls (hazard ratio: 1.37; CI: 1.15-1.63; P < 0.01), anaemia (hazard ratio: 1.61; CI: 1.10-2.38; P < 0.02) and osteoporosis (hazard ratio: 1.62; CI: 1.022.57; P < 0.04). Conclusion: patients with dementia frequently receive PIPs, and those who do are more likely to experience AHO. These results highlight the need to optimise medication in dementia patients, especially those with comorbidities. Product Details of 83-10-3.

Background: The Islamic Republic of Iran is at high risk of natural disasters. Households are the basic unit of society and they need to be prepared for disasters. Aims: This study assessed disaster preparedness among Iranian households in 2015. Methods: Using multistage cluster sampling, 2968 households in the catchment area of 53 public health departments in all 30 provinces of the Islamic Republic of Iran were surveyed on the disaster preparedness measures they had taken in the past year. The data collection questionnaire included 15 disaster preparedness measures. The mean preparedness score was calculated and its association with residence (urban versus rural), house ownership (owner versus renter) and education level of the head of the household (illiterate, elementary school, middle school, high school, university) was evaluated. Results: The mean score for household disaster preparedness was 9.3 out of 100 (95% confidence interval: 8.3-10.3). Multivariate analysis showed higher preparedness among rural than urban households (P = 0.02). Higher education level was positively associated with a higher preparedness score (P < 0.001), as was house ownership (P < 0.001). Conclusion: The level of household disaster preparedness in the Islamic Republic of Iran in 2015 was low. In line with the first priority for action of the Sendai Framework for Disaster Risk Reduction, the current study provides an overall picture of household disaster preparedness in the Islamic Republic of Iran. This estimation can be used as a baseline value for policy-making, planning, and evaluation of public awareness of disasters in the country.

HPLC of Formula: C12H12N2O3. I found the field of Acoustics; Radiology, Nuclear Medicine & Medical Imaging very interesting. Saw the article A real-time data-based scan conversion method for single element ultrasound transducers published in 2019, Reprint Addresses Csany, G (corresponding author), Pazmany Peter Catholic Univ, Fac Informat Technol & Bion, Budapest, Hungary.. The CAS is 83-10-3. Through research, I have a further understanding and discovery of 1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazole-4-carboxylic acid.

The current work investigates the performance of a real-time scan conversion algorithm for generating a 2-D ultrasound image from a laterally scanned single-element ultrasound transducer, which has applications in point-of-care devices such as for skin imaging. The algorithm employs a fixed calibration curve to update a predefined image grid in real time. Simulations showed that the calibration curve (with a maximum of 1) is robust to changes in scatterer concentration (8.3 x 10(-3) mean absolute error), signal to noise ratio (1.0 x 10(-3) mean absolute error for -5 dB SNR), and can be accurately predicted from a small number (31) of point scatterers (6.9 x 10(-3) mean absolute error). Good agreement was also found between the calibration curves obtained from simulated and experimental data (1.19 x 10(-2) mean absolute error). The scan conversion algorithm was validated by evaluation of the position estimation errors on both simulations and experiments. Clinical images of skin lesions (N = 20) demonstrate the feasibility of the algorithm for real, non-homogeneous tissue. Use of a fixed calibration curve compared to an adaptive calibration curve gave similar accuracies in the scanning step size range of 150-350 mu m (with an average overlap of the accuracy ranges of 92.94% for simulations and 42.83% for experiments), and a 350-fold improvement in computation time.

A new semi-theoretical equation is suggested for correlation of solid-liquid solubility data with temperature. The (solid + liquid) equilibrium for Terephthaldialdehyde, 4-Nitro-o-phennylenediamine, 2,4-dihydro- 5-methyl-2(4-methylphenyl)-3H-pyrazol-3-one (also named 1-(p-toly1)-3-methyl-5pyrazolone (PTMP)), 2-Amino-5-methylthiazole and 5-chloro-1-methyl-4-nitroimidazole in 18 solvents is correlated with semi-empirical models at temperatures T = 273.15 – 318.15 K under a pressure of 101.2 kPa. Moreover, a modified Apelblat model, lambda h model, Wilson model, NRTL model, new flexible equation as Akbari, Dideban and Farhang model (ADF) and for first time the modified Scatchard-Hildebrand equation were utilized to calculate the experiment values. The performance of both ADF and modified Scatchard-Hildebrand equation have been checked by calculating the solubility data with the AARD% of 1.3808% (for 775 data points) and 0.65% (for 100 data points), respectively. The Wilson model is applied to estimate the mixing Gibbs energy, mixing enthalpy, mixing entropy, activity coefficient (ln gamma(infinity)(1)) and reduced excess enthalpy (H-I(E,infinity)) at infinitesimal concentration were calculated.

A number of novel 6-R-isoxazolo[4,3-b]pyridines were synthesized and their reactions with neutral C-nucleophiles (1,3-dicarbonyl compounds, pi-excessive (het)arenes, dienes) were studied. The reaction rate was found to be dependent on the nature of the substituent 6-R. The most reactive 6-nitroisoxazolo[4,3-b]pyridines are able to add C-nucleophiles in the absence of a base under mild conditions. In addition, these compounds readily undergo [4+2]-cycloaddition reactions on aromatic bonds C=C(NO2) of the pyridine ring, thus indicating the superelectrophilic nature of 6-NO2-isoxazolo[4,3-b]pyridines.

The first Pd-catalyzed asymmetric allenylic [4+1] cycloaddition was successfully developed. Alternatively, tuning the Pd catalyst switched the reactivity toward an unprecedented [4+3] cycloaddition/cross-coupling. Ligands play a vital role in controlling the reaction pathway, allowing highly selective access to different products from identical substrates. Biological evaluation of the obtained compounds led to the discovery of new antitumor targets. A possible mechanism is proposed, suggesting two interesting catalytic cycles for the cycloaddition with palladium-butadienyls. This study also demonstrated the potential and utility of allenic esters as 1,4-biselectrophiles and C-4 synthons for participating in cycloaddition reactions.
