Initial respiratory support modality and outcome in preterm infants with less than 32 weeks of gestation in China: A multicentre retrospective cohort study.

Background: For initial respiratory management, continuous positive airway pressure (CPAP) is increasingly used for preterm infants, especially for gestational age less than 32 weeks. However, neonatologists are concerned about the potential risks of CPAP support failure.

Objectives: To examine the association between different initial respiratory support modalities and the outcomes of preterm infants at <32 weeks of gestation across multiple neonatal intensive care units (NICU) in China.

Clustering of Bacterial Growth Dynamics in Response to Growth Media by Dynamic Time Warping.

Bacterial growth curves, representing population dynamics, are still poorly understood. The growth curves are commonly analyzed by model-based theoretical fitting, which is limited to typical S-shape fittings and does not elucidate the dynamics in their entirety. Thus, whether a certain growth condition results in any particular pattern of growth curve remains unclear.

A decay effect of the growth rate associated with genome reduction in Escherichia coli.

Background: Bacterial growth is an important topic in microbiology and of crucial importance to better understand living cells. Bacterial growth dynamics are quantitatively examined using various methods to determine the physical, chemical or biological features of growing populations. Due to methodological differences, the exponential growth rate, which is a parameter that is representative of growth dynamics, should be differentiated.

Kresoxim-methyl Derivatives: Synthesis and Herbicidal Activities of (Pyridinylphenoxymethylene)phenyl Methoxyiminoacetates.

A series of new kresoxim-methyl derivatives, (pyridinylphenoxymethylene)phenyl methoxyiminoacetates, were synthesized and their structures were confirmed by NMR and high-resolution mass spectrometry (HRMS). Although derived from a fungicide, the bioassays indicated that several new compounds had good herbicidal activities. At 37.

Antioxidant flavonoids from the seed of Oroxylum indicum.

Three new flavonoid glycosides (1-3) and nineteen known compounds (4-22) were isolated from the aqueous ethanolic extract of the seed of Oroxylum indicum. The structures of 1-3 were elucidated on the basis of spectroscopic analysis. Antioxidant activities of all the isolated compounds were evaluated using a DPPH and an ORAC assay.
