Characterization of the key aroma compounds in the floral honey-like cup aroma of Fenghuang Dancong oolong tea by application of the sensomics approach.

The cup aroma (CA), a lingering scent in the empty cup after tea consumption, is important to sensory evaluation and overall experience; however, the compounds contributing to the distinct floral honey-like CA of Fenghuang Dancong oolong tea (FHDC) remain unknown. CA of FHDC had strong nectar, ginger-like, and floral, while the tea infusion (TA) was characterized by tropical fruit, sweet, and floral notes. OAV and GC-O analyses revealed that esters, aldehydes, and alcohols were major contributors to the CA, with distinct variations in the volatile compound profiles between TA and CA.

Helicobacter pylori modulates macrophage polarization via the glucocorticoid receptor to promote gastric cancer cell proliferation.

Background: Helicobacter pylori (H. pylori) is recognized as a major risk factor for gastric cancer (GC). However, the precise mechanism by which H.

The unique aroma of ripened Pu-erh tea, Liupao tea and Tietban tea: Associated post-fermentation condition and dominant microorganism with key aroma-active compound.

Dark tea with a unique aroma is a particular type of tea. Post-fermentation is the key manufacturing process that forms a unique aroma, distinguishing dark tea from other types of tea. Different post-fermentation conditions may be the reason for forming unique aromas in various dark teas.

Association between nurse-child communication and family caregivers' global ratings to hospital: a retrospective study.

Purpose: Effective nurse-child communication is a fundamental aspect of delivering pediatric nursing care. Family caregivers' global ratings to hospital are considered a proxy-reported measure for assessing a child's inpatient stay experience. We investigate the associations between nurse-child communication and family caregivers' global ratings to hospital.

The function of CD36 in infection.

CD36 is a scavenger receptor that has been reported to function as a signaling receptor that responds to pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) and could integrate metabolic pathways and cell signaling through its dual functions. Thereby influencing activation to regulate the immune response and immune cell differentiation. Recent studies have revealed that CD36 plays critical roles in the process of lipid metabolism, inflammatory response and immune process caused by infection.

An all-in-one magnetic SERS nanosensor for ratiometric detection of Escherichia coli in foods.

An all-in-one nanosensor was developed for the magnetic enrichment and ratiometric surface-enhanced Raman scattering (SERS) detection of Escherichia coli (E. coli). The all-in-one nanosensor was constructed through the chemical integration of four components into a single nanoparticle, which include a manganese ferrite nanoparticle serving as the magnetic core, a thin silver shell as the SERS substrate, a self-assembled layer of 4-mercaptobenzoic acid (MBA) molecules as the SERS internal standard, and a MBA-conjugated layer of aptamer sequences as the capture probe of E.

Use of Genetically Modified Bacteria to Repair Cracks in Concrete.

In this paper, we studied the crack-repair by spraying bacteria-based liquid around the cracks in concrete. To enhance the repair efficiency and speed up the repair process, the transposon mutagenesis method was employed to modify the genes of and create a mutant bacterial strain with higher efficiency of calcium carbonate productivity by catalyzing the combination of carbonate and calcium ion. The efficiency of crack-repairing in concrete by spraying two kinds of bacterial liquid was evaluated via image analysis, X-ray computed tomography (X-CT) scanning technology and the sorptivity test.

A Brief Review of the Shape Memory Phenomena in Polymers and Their Typical Sensor Applications.

In this brief review, an introduction of the underlying mechanisms for the shape memory effect (SME) and various shape memory phenomena in polymers is presented first. After that, a summary of typical applications in sensors based on either heating or wetting activated shape recovery using largely commercial engineering polymers, which are programmed by means of in-plane pre-deformation (load applied in the length/width direction) or out-of-plane pre-deformation (load applied in the thickness direction), is presented. As demonstrated by a number of examples, many low-cost engineering polymers are well suited to, for instance, anti-counterfeit and over-heating/wetting monitoring applications via visual sensation and/or tactual sensation, and many existing technologies and products (e.

H-NS is an activator of exopolysaccharide biosynthesis genes transcription in Vibrio parahaemolyticus.

Vibrio parahaemolyticus is capable of surviving in biofilm communities attached to biotic and abiotic surfaces. The exopolysaccharide (EPS) plays a key role in the maturing of the biofilm. The VPA1403-1412 (cpsA-J) operon is responsible for EPS production in V.
