The oxygenation constants （Ko2） of cobalt（Ⅱ） hydroxamates （CoL^1 2-CoL^3 2） with benzo-15-crown-5 （B15C5） pendants were measured over the range of -5 to ＋20 ℃, and the values of thermodynamic parameters （ΔH^0 and ΔS^0） were calculated based on these （Ko2） values, Meanwhile, these crowned complexes were employed to the oxidation for p-xylene to p-toluic acid with air at 110Δ under normal atmospheric pressure. The effects of B15C5 pendant and the length of chain bonded to B15C5 in these complexes on the O2-binding capabilities and oxidation for p-xylene were investigated with the comparison of crown-free analogues CoL^4 2.

Nosocomial infection （NI） is one of the most significant complications arising after open heart surgery, and leads to increased mortality, hospitalization time and health resource allocation. This study investigated the morbidity, mortality, and independent risk factors associated with NI following open heart surgery. We retrospectively surveyed the records of 1606 consecutive cardiovascular surgical patients to identify those that developed NI. The NI selection criteria were based on the Centers for Disease Control and Prevention （CDC） guidelines. The term NI encompasses surgical site infection （SSI）, central venous catheter-related infection （CVCRI）, urinary tract infection （UTI）, respiratory tract infection and pneumonia （RTIP）, as well as other types of infections. Of 1606 cardiovascular surgery patients, 125 developed NI （7.8%, 125/1606）. The rates of NI following surgery for congenital malformation, valve replacement, and coronary artery bypass graft were 2.6% （15/587）, 5.5% （26/473） and 13.6% （32/236）, respectively. The NI rate following surgical repair of aortic aneurysm or dissection was 16.8% （52/310）. Increased risk of NI was detected for patients with a prior preoperative stay 〉3 days （OR=2.11, 95% CI=1.39-3.20）, diabetes （OR=2.00, 95%=CI 1.26-3.20）, length of surgery 〉6 h （OR=2.26, 95% CI=1.47-3.47）, or postoperative cerebrovascular accident （OR=4.08, 95% CI=1.79-9.29）. Greater attention should be paid toward compliance with ventilator and catheter regulations in order to decrease NI morbidity and mortality following cardiovascular procedures.

A rare earth coordination system was first investigated as a new type of catalyst for the ring-openingpolymerization of α-amino acid N-carboxyanhydrides (NCAs). The results for the polymerization of γ-stearyl-α,L-glutamate(SLG) NCA using neodymium acetylacetonate (Nd(acac)_3)- or neodymium tris(2-ethylhexylphosphonate) (Nd(P_(204))_3)-triethylaluminum-water as catalysts were compared with those using conventional catalysts. It was found that the helicalpoly(γ-stearyl-L-glutamate) with high molecular weight as well as narrow molecular weight distribution can be obtained inthe presence of Nd(acac)_3/AlEt_3-1/2H_2O. The polymer obtained was characterized by IR and NMR spectroscopy.

The sympathetic nervous system plays a cardinal role in regulating cardiac function through releasing the neurotransmitter norepinephrine (NE). In comparison with ceniral nervous system, the molecular mechanism of NE uptake in myocardium is not clear. In present study we proved that in rat the CNS type of NE transporter (NET) was also expressed in middle cervical-stellate ganglion complex (MC-SG complex) which is considered to control the activity of heart, but not expressed in myocardium. The results also showed that NET expression level in right ganglion was significantly higher than in the left, rendering the greater capacity of NE uptake in right ventricle, a fact which may contribute to the maintenance of right ventricular function under pathologic state.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.
