Staphylococcal enterotoxins (SEs) serve as the primary cause of staphylococcal food poisoning and other foodborne intoxications. Among them, staphylococcal enterotoxin C (SEC) has the highest prevalence in dairy products, leading to multiple outbreaks all around the world. Thus, it is of great significance to develop a highly sensitive, highly specific and easy to operate chemiluminescent sandwich enzyme immunoassay (CLEIA) for detecting staphylococcal enterotoxin C (SEC1).

An imbalance in lymphatic fluid, whether it is caused by generation, transport, outflow, or dysfunctional vessels, can lead to lymphedema; however, the exact pathogenesis of this disease remains unclear. To explore the mechanism, we focused on the association among TRPML1, aquaporin-3 (AQP3), and aquaporin-5 (AQP5) in human lymphatic endothelial cells (HLECs). We explored the role of TRPML1 in altering the permeability of HLECs in lymphedema.

Nanocellulose aerogels are usually produced by methods such as freeze-drying or critical point drying, which have the disadvantages of high equipment requirements and high energy consumption. In this study, the Fe-containing ethanol bath was employed to dissolve and replace ice crystals in the prefrozen precursors of cellulose-based aerogels. The method achieved both solvent substitution and metal ion complexation and successfully prepared nanocellulose aerogels with a total solid concentration of 2.

Abnormal lipid accumulation is a fundamental contributor to obesity and metabolic disorders. Lipid droplets (LDs) and mitochondria (MT) serve as organelle chaperones in lipid metabolism and energy balance. LDs play a crucial role in lipid storage and mobilization, working in conjunction with MT to regulate lipid metabolism within the liver, brown adipose tissue, and skeletal muscle, thereby maintaining metabolic homeostasis.

The Qa-1 in mice is homologous to human leukocyte antigen E(HLA-E), and both of them belong to the non-classical major histocompatibility complex I b(MHC-I b) molecules. Qa-1 is capable of presenting self or exogenous antigen peptides to interact with two distinct receptors, namely T cell receptor (TCR) and natural killer cell group 2 member A (or C) (NKG2A/C), thus playing an important role in immune response and regulation. Qa-1-restricted regulatory CD8 T cell (CD8 Treg) is one of the most studied CD8 Treg subgroups, which can maintain immune homeostasis and autoimmune tolerance by exerting immunosuppressive effects.

Article Synopsis
  • Researchers created a new type of catalyst called FeNO/NC using a rapid heating method, which consists of iron, nitrogen, and carbon atoms.
  • The catalyst shows improved performance and durability for the oxygen reduction reaction (ORR) due to the interaction between iron-nitrogen and graphene that forms oxygen species.
  • Computational analysis suggests that this catalyst effectively manages the bonding and release of oxygen-related molecules, making it a strong candidate for developing advanced single-atom electrocatalysts.

Reference-frame-independent (RFI) quantum key distribution (QKD) presents promising advantages, especially for mobile-platform-based implementations, as it eliminates the need for active reference frame calibration. While RFI-QKD has been explored in various studies, limitations in key rate and distance persist due to finite data collection. In this study, we experimentally demonstrate an improved RFI-QKD protocol proposed by Zhu et al.

Rutin (Rut) is a flavonoid with pharmacological activities such as anti-inflammatory and antioxidant. Acrylamide (ACR) is a toxic substance widely found in human life that can induce neurotoxicity. Some studies have confirmed that neurotoxicity caused by ACR induces myelin damage, which in turn causes neurological dysfunction.
