SPP-5 affects larval arrest via insulin signaling pathway in Caenorhabditis elegans.

Diapause is an endocrine-mediated metabolic and growth arrest state in response to unfavorable external environments. The nematode Caenorhabditis elegans can enter diapause/arrest during embryonic, larval, or adult stages when subjected to detrimental external environments. Larval stage 1 (L1) arrest happens when animals hatch without food.

Comparison between hydrodynamic and ultrasound cavitation on the inactivation of lipoxygenase and physicochemical properties of soy milk.

The effects of hydrodynamic cavitation (HC) and ultrasound cavitation (UC) on the lipoxygenase activity and physicochemical properties of soy milk were evaluated. The results revealed that both ultrasound cavitation and hydrodynamic cavitation significantly inactivated the lipoxygenase activity. After the exposure to ultrasound cavitation at 522.

One-day thermal regime extends the lifespan in Caenorhabditis elegans.

Environmental factors, including temperature, can modulate an animal's lifespan. However, their underlying mechanisms remain largely undefined. We observed a profound effect of temperature on the aging of () by performing proteomic analysis at different time points (young adult, middle age, and old age) and temperature conditions (20 °C and 25 °C).

Simultaneous extraction and preliminary purification of polyphenols from grape pomace using an aqueous two-phase system exposed to ultrasound irradiation: Process characterization and simulation.

In this study, an ultrasound-assisted aqueous two-phase (ATP) extraction method was used for the extraction and purification of phenolic compounds from grape pomace. The effect of acoustic energy densities (AED, 41.1, 63.

Effects of Maillard Reaction on Volatile Compounds and Antioxidant Capacity of Cat Food Attractant.

In this study, self-made cat food attractant was prepared by Maillard reaction using hydrolysate of grass carp waste as raw material and glucose and cysteine hydrochloride as substrate. Its volatile compounds, antioxidant capacity, and pet palatability were investigated. The volatile compounds of attractants were analyzed using gas chromatography-mass spectrometry (GC-MS) which showed that alcohols and aldehydes were the most volatile in self-made attractants, accounting for 34.

Comparison between airborne ultrasound and contact ultrasound to intensify air drying of blackberry: Heat and mass transfer simulation, energy consumption and quality evaluation.

This study aimed at investigating the performances of air drying of blackberries assisted by airborne ultrasound and contact ultrasound. The drying experiments were conducted in a self-designed dryer coupled with a 20-kHz ultrasound probe. A numerical model for unsteady heat and mass transfer considering temperature dependent diffusivity, shrinkage pattern and input ultrasonic energies were applied to explore the drying mechanism, while the energy consumption and quality were analyzed experimentally.

Knockdown of adiponectin promotes the adipogenesis of goat intramuscular preadipocytes.

Intramuscular fat (IMF) content determined by the intramuscular preadipocytes differentiation has a huge influence on the sensory quality traits of meats. It was reported that the adiponectin () gene could promote adipocytes differentiation, but the underlying molecular and functional characterization of the for regulating goat IMF deposition remained unknown. Herein, the knockdown of was mediated by siRNAs during goat intramuscular preadipocytes differentiation.

Applications of water blanching, surface contacting ultrasound-assisted air drying, and their combination for dehydration of white cabbage: Drying mechanism, bioactive profile, color and rehydration property.

This work studied the influences of water blanching pretreatment (30 s), surface contacting ultrasound (492.3 and 1131.1 W/m) assisted air drying, and their combination on drying kinetics and quality of white cabbage.

Ultrasound assisted adsorption and desorption of blueberry anthocyanins using macroporous resins.

In this study, the impact of ultrasound on the adsorption and desorption features of blueberry anthocyanins on macroporous resins were studied. Sonication was performed at 106-279 W/L and 20-30 °C in a pulsed mode, respectively. Generally, ultrasound treatments within the selected experimental range enhanced the adsorption/desorption process of anthocyanins on macroporous resins.

[The gene expression patterns of genetic P77PMC epilepsy-prone rats' hippocampus].

Objective: To find out the differentially expressed genes in the hippocampus of the rats with genetic epilepsy so as to lay a foundation for exploring the pathogenesis of epilepsy by means of cDNA array technology.

Methods: Gene expression patterns in the hippocampus of the genetic epilepsy-prone P77PMC rats and normal Wistar rats were established using the alpha-32P-labeled cDNA probes hybridized with the Atlas Rat cDNA Expression Array, and then were analyzed by an image analysis instrument to get the differentially expressed genes.

Results: Fifteen genes were found having differential expression patterns in hippocampus between the P77PMC rats and the Wistar rats, while there may be many other differentially expressed genes left undiscovered due to having no appropriate image analysis software.

[Temporal lobe epilepsy model induced by pilocarpine in rats].

Objective: To characterize the acute and chronic behavioral, electrographic and histological changes of sustained seizures induced by pilocarpine in rats.

Methods: The rats in the study were divided into the experimental group and control group. After status epilepticus (SE) was induced in the experimental rats, the surviving animals were continuously monitored for 6 h-60 days.

Analysis of gene expression in genetic epilepsy-prone rat using a cDNA expression array.

Unlabelled: Our aim is to search the differential expression genes of genetic epilepsy and establish the groundwork of exploring the pathogenesis of epilepsy on the gene level by using cDNA array technology.

Methods: Gene expression profiles of the cerebral cortex of genetic epilepsy-prone P77PMC rats and normal Wistar rats were established using the Atlas Rat cDNA Expression Array. The difference between gene expression profiles was analyzed using an image analysis instrument.
