An enantioselective Mannich reaction between 3-fluorooxindoles and pyrazolinone ketimines has been developed for the construction of amino-pyrazolone-oxindoles containing stereogenic C-F units. Based on this new protocol that allows for the generation of two adjacent tetrasubstituted stereocenters, a variety of structurally diverse fluorinated amino-pyrazolone-oxindoles were obtained in good to excellent yields with excellent diastereoselectivities and enantioselectivities (up to 98% yield, >20 : 1 dr and >99% ee). What’s more, good yield and high stereoselectivities were obtained in the gram-scale reaction.

Background: The high prevalence of physician burnout, particularly in emergency medicine, has garnered national attention in recent years. Objective means of measuring stress while at work can facilitate research into stress reduction interventions, and wearable photoplethysmography (PPG) technology has been proposed as a potential solution. However, the use of low-burden wearable biosensors to study training and clinical practice among emergency physicians (EP) remains untested. Objective: This pilot study aimed to (1) determine the feasibility of recording on-shift photoplethysmographic data from EP, (2) assess the quality of these data, and (3) calculate standard pulse rate variability (PRV) metrics from the acquired dataset and examine patterns in these variables over the course of an academic year. Methods: A total of 21 EP wore PPG biosensors on their wrists during clinical work in the emergency department during a 9-hour shift. Recordings were collected during the first quarter of the academic year, then again during the fourth quarter of the same year for comparison. The overall rate of usable data collection per time was computed. Standard pulse rate (PR) and PRV metrics from these two time points were calculated and entered into Student t tests. Results: More than 400 hours of data were entered into these analyses. Interpretable data were captured during 8.54% of the total recording time overall. In the fourth quarter of the academic year compared with the first quarter, there was no significant difference in median PR (75.8 vs 76.8; P=.57), mean R-R interval (0.81 vs 0.80; P=.32), SD of R-R interval (0.11 vs 0.11; P=.93), root mean square of successive difference of R-R interval (0.81 vs 0.80; P=.96), low-frequency power (3.5×103 vs 3.4×103; P=.79), high-frequency power (8.5×103 vs 8.3×103; P=.91), or low-frequency to high-frequency ratio (0.42 vs 0.41; P=.43), respectively. Power estimates for each of these tests exceeded .90. A secondary analysis of the resident-only subgroup similarly showed no significant differences over time, despite power estimates greater than .80. Conclusions: Although the use of PPG biosensors to record real-time physiological data from EP while providing clinical care seems operationally feasible, this study fails to support the notion that such an approach can efficiently provide reliable estimates of metrics of interest. No significant differences in PR or PRV metrics were found at the end of the year compared with the beginning. Although these methods may offer useful applications to other domains, it may currently have limited utility in the contexts of physician training and wellness.

Ampelocalamus scandens is native to Guizhou Province, China, and grows at an altitude of 260-320 m. It can be used as a raw material for weaving and papermaking. In the current study, the complete chloroplast (cp) genome of A. scandens was sequenced and is reported for the first time. The complete cp sequence was 139,504 bp, include large single-copy (LSC), small single-copy (SSC), and a pair of invert repeats (IR) region of 83,103 bp, 12,813 bp, and 21,793 bp, respectively. Besides, the plastid genome comprised a total of 132 genes, including protein-coding, tRNA, and rRNA genes as 85, 39, and 8 genes, respectively. Phylogenetic analysis based on 28 cp genomes reveals that A. scandens is closely associated with Ampelocalamus melicoideus in Arundinarodae.

Unsymmetrical pincers have been shown to be better than the corresponding symmetrical pincers in several catalysis reactions. A new unsymmetrical PNN propincer, 2-(3,5-dimethylpyrazolylmethyl)-5-(diphenylphosphinomethyl)-pyrrole (1), was synthesized from pyrrole through Mannich bases in a good yield. In addition, the new byproduct 2-(3,5-dimethylpyrazolylmethyl)-5-(dimethylaminomethyl)-N-(hydroxymethyl)pyrrole was also isolated. The reaction of 1 with [PdCl2(PhCN)(2)] and Et3N in toluene yielded [PdCl-{C4H2N-2-(CH(2)Me(2)pz)-5-(CH2PPh2)-kappa P-3,N,N}] (2). The analogous reaction between 1 and [NiCl2(DME)] or NiX2 (X = Br, I) in the presence of NEt3 in acetonitrile afforded [NiX{C4H2N-2-(CH(2)Me(2)pz)-5-(CH2PPh2)-kappa P-3,N,N}] (3; X = Cl, Br, I). All complexes were structurally characterized. The norbornene polymerization behaviors of the unsymmetrical pincer complexes 2 and 3 in the presence of MMAO or EtAlCl2 were compared with those of the symmetrical pincer complexes chloro[2,5-bis(3,5-dimethylpyrazolylmethyl)pyrrolido]-palladium(II) (NNN), chloro[2,5-bis(diphenylphosphinomethyl)pyrrolido]palladium(II), and chloro[2,5-bis(diphenylphosphinomethyl)pyrrolido]nickel(II) (PNP) at different temperatures. The PNN and NNN complexes exhibited far greater activity on the order of 10(7) g of PNB/mol/h, with quantitative yields in some cases, in comparison to the PNP pincer palladium and nickel complexes. This trend was also supported by the Pr-i group substituted PNP nickel and palladium pincer complexes. These polymerization behaviors are explained using steric crowding around the metal atom with the support of NMR studies and suggested that the activity increases as the N-pyrazole donor increases. Polymers were characterized by H-1 NMR, IR, TGA, and powder XRD methods.

COA of Formula: C5H8N2. I found the field of Chemistry; Energy & Fuels; Materials Science very interesting. Saw the article Chemical and electrochemical water oxidation mediated by bis(pyrazol-1-ylmethyl)pyridine-ligated Cu(i) complexes published in 2021.0, Reprint Addresses Swarts, AJ (corresponding author), Northwest Univ, Res Focus Area Chem Resource Beneciat, Catalysis & Synth Res Grp, 11 Hoffman St, ZA-2531 Potchefstroom, South Africa.; Swarts, AJ (corresponding author), Univ Witwatersrand, Sch Chem, Mol Sci Inst, ZA-2050 Johannesburg, South Africa.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

Herein a series of novel bis(pyrazol-1-ylmethyl)pyridine-ligated Cu(i) complexes, C1-C4, bearing different donating groups [[H(C1), Me(C2), t-Bu(C3), Ph(C4)])] on the pyrazole rings, were synthesized and investigated as pre-catalysts in chemical and electrocatalytic water oxidation reactions. Ligands, 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine (L1), 2,6-bis((1H-pyrazol-1-yl)methyl)pyridine (L2), 2,6-bis((3,5-di-tert-butyl-1H-pyrazol-1-yl)methyl)pyridine (L3), and 2,6-bis((3,5-diphenyl-1H-pyrazol-1-yl)methyl)pyridine (L4) were reacted with Cu(MeCN)(4)PF6 to form complexes C1-C4 respectively. Cerium ammonium nitrate (CAN), sodium m-periodate, and sodium persulfate were investigated as chemical oxidants in chemical water oxidation. Complexes C1-C4 showed catalytic activity towards chemical water oxidation in the presence of CAN as the primary oxidant at 25 degrees C. Complex C2 was the most active with a turnover number (TON) of 4.6 and a turnover frequency (TOF) of 0.31 s(-1). The least active catalyst was complex C4, with a TON of 2.3 and a TOF of 0.0086 s(-1). This observed difference in catalytic activity between the complexes illustrated the key role that electronic effects play during catalysis. Other oxidants evaluated with C2 were sodium m-periodate (TON, 3.77; TOF 0.14 s(-1)) and sodium persulfate (TON, 4.02; TOF 0.044 s(-1)) however, CAN exhibited the greatest activity. Complexes C1-C4 were investigated in electrocatalytic water oxidation at a neutral pH of 6.5. Complex C2 was the most active in electrocatalytic water oxidation as well, exhibiting an overpotential of 674 mV and TOF of 9.77 s(-1) (at 1.7 V vs. NHE), which is better than most reported copper(ii) complexes. These Cu(i) complexes C1-C4 show potential as efficient chemical and electrocatalytic water oxidation catalysts, which can be achieved by fine-tuning the steric and electronic properties of the catalysts.

Purpose Sepsis survivors have a higher risk of rehospitalisation and of long-term mortality. We assessed the rate, diagnosis, and independent predictors for rehospitalisation in adult sepsis survivors. Methods We searched for non-randomized studies and randomized clinical trials in MEDLINE, Cochrane Library, Web of Science, and EMBASE (OVID interface, 1992-October 2019). The search strategy used controlled vocabulary terms and text words for sepsis and hospital readmission, limited to humans, and English language. Two authors independently selected studies and extracted data using predefined criteria and data extraction forms. Results The literature search identified 12,544 records. Among 56 studies (36 full and 20 conference abstracts) that met our inclusion criteria, all were non-randomised studies. Studies most often report 30-day rehospitalisation rate (mean 21.4%, 95% confidence interval [CI] 17.6-25.4%; N = 36 studies reporting 6,729,617 patients). The mean (95%CI) rehospitalisation rates increased from 9.3% (8.3-10.3%) by 7 days to 39.0% (22.0-59.4%) by 365 days. Infection was the most common rehospitalisation diagnosis. Risk factors that increased the rehospitalisation risk in sepsis survivors were generic characteristics such as older age, male, comorbidities, non-elective admissions, hospitalisation prior to index sepsis admission, and sepsis characteristics such as infection and illness severity, with hospital characteristics showing inconsistent associations. The overall certainty of evidence was moderate for rehospitalisation rates and low for risk factors. Conclusions Rehospitalisation events are common in sepsis survivors, with one in five rehospitalisation events occurring within 30 days of hospital discharge following an index sepsis admission. The generic and sepsis-specific characteristics at index sepsis admission are commonly reported risk factors for rehospitalisation. Registration PROSPERO CRD 42016039257, registered on 14-06-2016.

In this letter, an efficient one-pot asymmetric sequential reaction is achieved by organo/transition metal relay catalysis in constructing two consecutive C-C bonds, which involves enantioselective amino squaramide catalytic Mannich-type addition of pyrazolones to isatin-derived ketimines and a subsequent palladium catalyzed diastereoselective allylic alkylation of pyrazolones with allylic acetates. An array of novel pyrazolone-aminooxindole-propylene structural motifs are obtained in a high level of yield and with excellent enantio- and diastereoselectivity (up to 95% yield, >20:1 dr, >99% ee). This methodology features the formation of vicinal quarternary carbon-stereocenters, and the second all-carbon tetrasubstituted stereogenic center is induced by joint action of the achiral palladium catalysis and the chiral environment generated from the Mannich step. Moreover, the usefulness of this methodology is highlighted by converting the allylic product into the carbonyl compound.

Quinone based compounds display activation in hypoxia, an environment prevalent in tumours. We have synthesized a bis(pyrazole) based 1,4-quinone compound suitable for metal chelation. The quinone (L2) converted to hydroquinone (H(2)L1) during the complex synthesis leading to [Ru-II(eta(6)-p-cym)(H(2)L1)Cl](PF6) (1). We found from ‘FINMR studies that in the methanolic solution L2 stoichiometrically converted to H(2)L1 while oxidizing the methanol to formaldehyde. L2 crystallized in monoclinic space group I2/a while complex 1 crystallizes in P2(1)/c. Cyclic voltammetry of the redox non-innocent L2 showed quasi-reversible (Delta Ep = 67 mV) redox behaviour with E-1/2 at 0.12 V w.r.t. NHE. Complex 1 is stable at pH 7.4 in presence of 4 mM chloride and does not hydrolyse even up to 24 h. L2 showed IC50, values of 155 and 123 mu M against metastatic breast adenocarcinoma (MDA-MB231) and pancreatic carcinoma (MIA PaCa-2) respectively. L2 gets activated by ca. 2.7-fold in hypoxia against MIA PaCa-2 cells. The mechanistic studies showed ROS accumulation and oxidation of NADH to NAD(+), which may be responsible for the cytotoxicity. The reactivity studies showed that conversion to hydroquinone by reaction with NADH or glutathione is irreversible. Complex 1 is not cytotoxic up to 100 mu M in normoxia or hypoxia. Complex 1 displays irreversible redox behavior in cyclic voltammetry displaying two overlapping oxidation peaks at 1.00 and 1.57 V w.r.t. NHE, which may be assigned to the conversion of hydroquinone to quinone and Ru-II -> Ru-III respectively.
