A multi-scale time-series dataset with benchmark for machine learning in decarbonized energy grids.

The electric grid is a key enabling infrastructure for the ambitious transition towards carbon neutrality as we grapple with climate change. With deepening penetration of renewable resources, the reliable operation of the electric grid becomes increasingly challenging. In this paper, we present PSML, a first-of-its-kind open-access multi-scale time-series dataset, to aid in the development of data-driven machine learning (ML)-based approaches towards reliable operation of future electric grids.

Low-energy green light alleviates senescence-like phenotypes in a cell model of photoaging.

Background: Ultraviolet B (UVB) affects diverse pathways in skin cells, resulting in skin photoaging. Skin fibroblasts internalize and degrade elastin and collagen, playing prominent roles in photoaging. Green light is used in many fields of dermatology, but few studies have examined its role in photoaging.

Spontaneously Restoring Specific Bioaffinity of RGD in Linear RGD-containing Peptides by Conjugation with Zwitterionic Dendrimers.

Peptides are more versatile than small molecule drugs, but their specific bioaffinities are usually lower than their original native proteins because of the loss of preferred conformations. To overcome this key obstacle, we demonstrated a hydrogen bond-induced conformational constraint method to enhance the specific bioaffinities of peptides to achieve a high success rate by using linear RGD-containing peptides as a model of bioactive peptides. By performing molecular simulation, we found that the chemically immobilized linear CRGDS via cysteine (C) at the N-terminus on zwitterionic PAMAM G-5 can not only spontaneously restore the natural conformation of the RGD segment through the assistance of the dynamic hydrogen bond from serine (S) at the C-terminus of the peptide, but it can also narrow the distribution of all possible conformations.

As results, 33 PPCPs were detected in water and sediment of the lake.

A lineage-specific arginine in POS1 is required for fruit size control in Physaleae (Solanaceae) via gene co-option.

Solanaceae have important economic value mainly due to their edible fruits. Physalis organ size 1/cytokinin response factor 3 (POS1/CRF3), a unique gene in Solanaceae, is involved in fruit size variation in Physalis but not in Solanum. However, the underlying mechanisms remain elusive.

The Relationship Between Feedback Quality, Perceived Organizational Support, and Sense of Belongingness Among Conscientious Teleworkers.

The belongingness literature has largely examined the antecedents of non-teleworkers' sense of belongingness, but little attention has been paid to what job-related factors could affect teleworkers' sense of belongingness. Grounded in organizational support theory, our research focuses on why feedback quality from the direct leader brings sense of belongingness and considers how conscientiousness of teleworkers shapes this effect. Based on data from 329 participants obtained at three different time points from one technology service organization in China, our results indicated that teleworkers' perceived organizational support serves as an essential mediator of the positive relationship between feedback quality from the direct leader and sense of belongingness.

CAR T cells equipped with a fully human scFv targeting Trop2 can be used to treat pancreatic cancer.

Purpose: Chimeric antigen receptor (CAR) T cell therapy has demonstrated clinical success in treating haematologic malignancies but has not been effective against solid tumours thus far. Trop2 is a tumour-related antigen broadly overexpressed on a variety of tumours and has been reported as a promising target for pancreatic cancers. Our study aimed to determine whether CAR T cells designed with a fully human Trop2-specific single-chain fragment variable (scFv) can be used in the treatment of Trop2-positive pancreatic tumours.

Results: A total of 72, 74, 39, 38 CXE genes were identified in Gossypium barbadense, Gossypium hirsutum, Gossypium raimondii and Gossypium arboreum, respectively. The gene structure and expression pattern were analyzed.

Mediator Engineering of To Improve Multidimensional Stress Tolerance.

Saccharomyces cerevisiae is a well-performing workhorse in chemical production, which encounters complex environmental stresses during industrial processes. We constructed a multiple stress tolerance mutant, Med15, that was obtained by engineering the KIX domain of Mediator tail subunit Med15. Med15 interacted with transcription factor Hap5 to improve expression for sterol homeostasis for decreasing membrane fluidity and thereby enhancing acid tolerance.

Chimeric antigen receptors containing the OX40 signalling domain enhance the persistence of T cells even under repeated stimulation with multiple myeloma target cells.

Persistence of CAR-T cell function is associated with relapse rate after CAR-T therapy, while co-stimulatory agents are highly concerned with the persistence of CAR-T cells. In this study, we designed and constructed a series of BCMA-targeting second-generation CAR constructs containing CD28, 41BB, and OX40 molecules, respectively, to identify the costimulatory domains most favorable for persistence. The results of routine in vitro studies showed that OX40-CAR-T and 41BB-CAR-T had similar antitumor effects and were superior to CD28-CAR-T in terms of proliferation and cytotoxicity.
