Preoperative integrated oxidative stress score as a prognostic factor for predicting clinical outcomes in breast cancer patients received neoadjuvant chemotherapy: a real-world retrospective study.

The current study aims to investigate the prognostic value of breast cancer integrated oxidative stress score (BCIOSS) in patients with breast cancer who received neoadjuvant chemotherapy (NACT). A retrospective analysis of 104 breast cancer patients who underwent NACT from June 2009 to December 2015 was performed. The differences of BCIOSS of breast cancers in regard to variables were analyzed using Chi-square test and Fisher's exact test.

Kurarinone Attenuates LPS-Induced Pneumonia by Inhibiting MAPK and NF-κB Signaling Pathways.

Kurarinone is a prenylated flavanone isolated from Sophora flavescens Aiton. This investigation aimed to elucidate whether kurarinone could ameliorate lipopolysaccharide (LPS)-induced pneumonia and explore the underlying mechanism. C57BL/6 mice were treated with LPS (50 μg/20 μL) to establish pneumonia models.

A Signal-Harmonizing Hybrid Neural Pathway Enabled by Bipolar-Chemo-Synapse Spiking Interneuron.

To realize human-machine fusion, a hybrid neural pathway operating in the same modality with biological systems becomes imperative, which requires an interneuron unit to encode information in biorecognizable spike sequences and tune the frequency upon excitatory and inhibitory neurotransmitters. Existing artificial interneurons cannot encode information upon different neurotransmitters, and the activation threshold and frequency responsivity do not align with those of biological counterparts, leading to limited success in constructing a signal-harmonizing hybrid neural pathway for neuroprosthetics, neurorehabilitation, and other neuroelectronic applications. Herein, we develop a bipolar-chemosynapse interneuron to encode the spike frequency in a highly bionic paradigm.

Position-dependent resource competition within inflorescences of Sagittaria trifolia.

Resource competition among flowers is expected to influence variation in seed output within inflorescences, but the extent to which flower position affects competitive interactions is still incompletely understood. To investigate position effects on seed output in the perennial, monoecious macrophyte Sagittaria trifolia, we compared components of seed production (fruit set, seed number per fruit, and seed size) in control inflorescences to that in inflorescences from which half of the female flowers were experimentally removed, either from basal positions, from upper positions, or from across the inflorescence. Basal and upper flower removal reduced total seed output per inflorescence, while the throughout removal treatment maintained a seed yield comparable to the control.

Duplicated TLRs Possess Sub- and Neo-Functionalization to Broaden Their Ligand Recognition in Crucian Carp (Carassius auratus).

Toll-like receptors (TLRs) play a crucial role in the immune response to pathogen invasion. The TLR response patterns in teleost are significantly different from those in mammals. In this study, we systematically identified and characterized the TLR family of crucian carp (Carassius auratus).
