Formation and control of heterocyclic amines and advanced glycation end products in traditional Chinese braised pork belly: The role of food additives.

For braised pork belly, a popular traditional Chinese dish, we lack a scientific knowledge to reduce the formation of harmful heterocyclic amines (HAs) and advanced glycation end products (AGEs) while maintaining sensory quality. This study aimed to clarify the factors affecting the formation of free and protein-bound HAs and AGEs during the braised pork belly cooking process using UPLC-MS/MS analysis. The results indicated that soy sauce significantly promoted the formation of HAs, with organic soy sauce exhibiting the strongest promoting effect, increasing HAs by 270.

Harnessing β-glucan conjugated quercetin nanocomplex to function as a promising anti-inflammatory agent via macrophage-targeted delivery.

Quercetin, a promising anti-inflammatory agent, faces challenges related to poor bioavailability and limited practical applications. β-glucan, a natural polysaccharide, can be specifically recognized by macrophages, making it an ideal targeting carrier to enhance therapeutic efficacy for macrophage-related dysfunctions. In this study, β-glucan conjugated quercetin nano-complexes (CM-Cur@QT) were developed to target macrophage and alleviate pro-inflammatory response in M1-like macrophages.

Reward history guides focal attention in whisker somatosensory cortex.

Prior reward is a potent cue for attentional capture, but the underlying neurobiology is largely unknown. In a novel whisker touch detection task, we show that mice flexibly shift attention between specific whiskers on a trial-by-trial timescale, guided by the recent history of stimulus-reward association. Two-photon calcium imaging and spike recordings revealed a robust neurobiological correlate of attention in the somatosensory cortex (S1), boosting sensory responses to the attended whisker in L2/3 and L5, but not L4.

Magnetothermal-activated gene editing strategy for enhanced tumor cell apoptosis.

Precise and effective initiation of the apoptotic mechanism in tumor cells is one of the most promising approaches for the treatment of solid tumors. However, current techniques such as high-temperature ablation or gene editing suffer from the risk of damage to adjacent normal tissues. This study proposes a magnetothermal-induced CRISPR-Cas9 gene editing system for the targeted knockout of HSP70 and BCL2 genes, thereby enhancing tumor cell apoptosis.

Multimodal locomotion ultra-thin soft robots for exploration of narrow spaces.

From power plants on land to bridges over the sea, safety-critical built environments require periodic inspections for detecting issues to avoid functional discontinuities of these installations. However, navigation paths in these environments are usually challenging as they often contain difficult-to-access spaces (near-millimetre and submillimetre-high gaps) and multiple domains (solid, liquid and even aerial). In this paper, we address these challenges by developing a class of Thin Soft Robots (TS-Robot: thickness, 1.

An online-predictive model of acute kidney injury after pancreatic surgery.

Objective: Acute kidney injury(AKI) after pancreatic surgery is associated with increased mortality, longer hospital stays and poor prognosis. This study aims to identify the risk factors and establish an easy-to-use prediction calculator by the nomogram to predict the risk of AKI after pancreatic surgery.

Methods: From January 2016 to June 2018, 1504 patients who underwent pancreatic surgery in our center were included in this retrospective analysis and randomly assigned to primary (1054 patients) and validation (450 patients) cohorts.

A review of green methods used in starch-polyphenol interactions: physicochemical and digestion aspects.

The interactions of starch with lipids, proteins, and other major food components during food processing are inevitable. These interactions could result in the formation of V-type or non-V-type complexes of starch. The starch-lipid complexes have been intensively studied for over five decades, however, the complexes of starch and polyphenols are relatively less studied and are the subject of recent interest.

A novel insight into green food preservation: Design of equilibrium modified atmosphere packaging (EMAP) based on gas barrier (GB) - gas conductor (GC) blending materials.

In this work, the design of equilibrium modified atmosphere packaging (EMAP) was achieved by adjusting gas permeability using gas barrier (GB) - gas conductor (GC) blending material. Sulfonated poly ether ether ketone (SPEEK) was used as promoter for gas permeation, i.e.

Polarity Control within One Monolayer at ZnO/GaN Heterointerface: (0001) Plane Inversion Domain Boundary.

In semiconductor heterojunction, polarity critically governs the physical properties, with an impact on electronic or optoelectronic devices through the presence of pyroelectric and piezoelectric fields at the active heteropolar interface. In the present work, the abrupt O-polar ZnO/Ga-polar GaN heterointerface was successfully achieved by using high O/Zn ratio flux during the ZnO nucleation growth. Atomic-resolution high-angle annular dark-field and bright-field transmission electron microscopy observation revealed that this polarity inversion confines within one monolayer by forming the (0001) plane inversion domain boundary (IDB) at the ZnO/GaN heterointerface.
