Gambogenic acid induces apoptosis via upregulation of Noxa in oral squamous cell carcinoma.

Gambogenic acid (GNA), a bioactive compound derived from the resin of Garcinia hanburyi, has demonstrated significant antitumor properties. However, its mechanisms of action in oral squamous cell carcinoma (OSCC) remain largely unclear. This study aimed to elucidate the apoptotic effects of GNA on OSCC cell lines CAL-27 and SCC-15.

MLKL promotes hepatocarcinogenesis through inhibition of AMPK-mediated autophagy.

The pseudokinase mixed lineage kinase domain-like (MLKL) is an essential component of the activation of the necroptotic pathway. Emerging evidence suggests that MLKL plays a key role in liver disease. However, how MLKL contributes to hepatocarcinogenesis has not been fully elucidated.

CoAlO/Kaoline Hybrid Pigment Prepared via Solid-Phase Method for Anticorrosion Application.

In this study, kaoline is incorporated to prepare CoAlO/kaoline hybrid pigments traditional solid-state reaction, and the introduction of kaoline decreases the preparation temperature for formation of spinel CoAlO, and reduces the production cost of cobalt blue as well. More importantly, kaoline may participate in the crystallization of spinel CoAlO during calcining process, and the hybrid pigments prepared using 8.1% CoO and 81.

Formation and Coloring Mechanism of Typical Aluminosilicate Clay Minerals for CoAlO Hybrid Pigment Preparation.

Different kinds of aluminosilicate minerals were employed to fabricate CoAlO hybrid pigment for studying its formation and coloring mechanism. It revealed that the color of the obtained hybrid pigments was determined by the content of AlO and lightness of clay minerals. The higher the AlO content and the lightness of clay minerals, the better the color parameters of hybrid pigments.

Standard metabolic rate predicts growth trajectory of juvenile Chinese crucian carp () under changing food availability.

Phenotypic traits vary greatly within populations and can have a significant influence on aspects of performance. The present study aimed to investigate the effects of individual variation in standard metabolic rate (SMR) on growth rate and tolerance to food deprivation in juvenile Chinese crucian carp () under varying levels of food availability. To address this issue, 19 high and 16 low SMR individuals were randomly assigned to a satiation diet for 3 weeks, whereas another 20 high and 16 low SMR individuals were assigned to a restricted diet (approximately 50% of satiation) for the same period.

Interspecific differences in hypoxia-induced gill remodeling in carp.

The gills of many fish, but in particular those of crucian carp (Carassius carassius) and goldfish (Carassius auratus), are capable of extensive remodeling in response to changes in oxygen (O2), temperature, and exercise. In this study, we investigated the interspecific variation in hypoxia-induced gill modeling and hypoxia tolerance in 10 closely related groups of cyprinids (nine species, with two strains of Cyprinus carpio). There was significant variation in hypoxia tolerance, measured as the O2 tension (P(O2)) at which fish lost equilibrium (LOEcrit), among the 10 groups of carp.

Interspecific variation in hypoxia tolerance, swimming performance and plasticity in cyprinids that prefer different habitats.

This study quantified and compared hypoxia tolerance and swim performance among cyprinid fish species from rapid-, slow- and intermediate-flow habitats (four species per habitat) in China. In addition, we explored the effects of short-term acclimation on swim performance, maximum metabolic rate (M(O2,max)) and gill remodelling to detect habitat-associated patterns of plastic response to hypoxia. Indices of hypoxia tolerance included oxygen threshold for loss of equilibrium (LOE50) and aquatic surface respiration (ASR50), and critical oxygen tension for routine metabolic rate (Pcrit).

Habitat-specific locomotor variation among Chinese hook snout carp (Opsariichthys bidens) along a river.

The Wujiang River is a tributary of the upper Yangtze River that shows great variations in its flow regime and habitat condition. Dams have been built along the Wujiang River and have altered the habitats profoundly enough that they may give rise to reproductive isolation. To test whether the swimming performance and morphology of the Chinese hook snout carp (Opsariichthys bidens), varied among habitats and whether the possible differences had a genetic basis, we measured the steady and unsteady swimming performance, external body shape and genetic distance among fish collected from both the main and tributary streams of the upper, middle and lower reaches along the river.

Study on the adsorption feature of rutin aqueous solution on macroporous adsorption resins.

The adsorption feature of different kinds of polystyrene-based macroporous adsorption resins (MARs) was investigated systemically at constant temperature employing Rutin as the adsorbate. Different from traditional adsorption patterns, Langmuir and Freundlich adsorption, and the results showed interesting aspects: (1) With the increase of the volume of the initial solution, the adsorption capacity increased to the maximum, and then decreased gradually. (2) Experimental results clearly verified the opinion that the adsorption process of MARs could be divided into three stages-macropores, mesopores, and micropores-by the capillary effects occurring at the two intersections, and the adsorption feature for every stage could be described well by the fourth type of Brunauer model.
