Sucralose uses reward pathways to promote acute caloric intake.

Non-nutritive sweeteners (NNSs) are used to reduce caloric intake by replacing sugar with compounds that are sweet but contain little or no calories. In this study, we investigate how non-nutritive sweetener sucralose to promote acute food intake in the fruit fly Drosophila melanogaster. Our results showed that acute exposure to NNSs sweetness induces a robust hyperphagic response in flies.

ABC2A: A Straightforward and Fast Method for the Accurate Backmapping of RNA Coarse-Grained Models to All-Atom Structures.

RNAs play crucial roles in various essential biological functions, including catalysis and gene regulation. Despite the widespread use of coarse-grained (CG) models/simulations to study RNA 3D structures and dynamics, their direct application is challenging due to the lack of atomic detail. Therefore, the reconstruction of full atomic structures is desirable.

Ulinastatin inhibits the metastasis of nasopharyngeal carcinoma by involving uPA/uPAR signaling.

Distant metastasis is the primary reason for treatment failure in patients with nasopharyngeal carcinoma (NPC). In this study, we investigated the effect of ulinastatin (UTI) on NPC metastasis and its underlying mechanism. Highly-metastatic NPC cell lines S18 and 58F were treated with UTI and the effect on cell proliferation, migration, and invasion were determined by MTS and Transwell assays.

Upstream and downstream regulators of Klotho expression in chronic kidney disease.

Klotho is a critical protein that protects the kidney. Klotho is severely downregulated in chronic kidney disease (CKD), and its deficiency is implicated in the pathogenesis and progression of CKD. Conversely, an increase in Klotho levels results in improved kidney function and delays CKD progression, supporting the notion that modulating Klotho levels could represent a possible therapeutic strategy for CKD treatment.

Mediating effects of self-esteem on the relationship between mindful parenting and social anxiety level in Chinese adolescents.

This study aimed to investigate the relationship between mindful parenting and social anxiety level in Chinese adolescents and to explore the mediating roles of self-esteem between mindful parenting and social anxiety level. A total of 302 adolescents and their main caregivers were investigated by using the Chinese version of the Mindful Parenting Scale, Self-Esteem Scale and the Center for Epidemiological Studies Depression Scale and the Social Anxiety Scale. Related analysis was used to investigate the relationship between mindful parenting, self-esteem and social anxiety level.

Protective Effect and Mechanism of Kuntai Capsule on Angiotensin II -Induced Hypertension in Ovariectomized Rats.

Objective: To explore the protective effect and mechanism of Kuntai (KT) Capsule on angiotensin II (Ang II)-induced hypertension in ovariectomized (OVX) rats.

Methods: Fifty-four rats were randomly divided into 6 groups according to a random number table, 9 in each group: control, OVX sham+Ang II, OVX, OVX+Ang II, OVX+Ang II +E, and OVX+Ang II +KT. OVX rats model was constructed by retroperitoneal bilateral ovariectomy.

Programmable mismatch-fueled high-efficiency DNA signal amplifier.

Herein, by introducing mismatches, a high-efficiency mismatch-fueled catalytic multiple-arm DNA junction assembly (M-CMDJA) with high-reactivity and a high-threshold is developed as a programmable DNA signal amplifier for rapid detection and ultrasensitive intracellular imaging of miRNA. Compared with traditional nucleic acid signal amplification (NASA) with a perfect complement, the M-CMDJA possesses larger kinetic and thermodynamic favorability owing to the more negative reaction standard free energy (Δ) as driving force, resulting in much higher efficiency and rates. Once traces of the input initiator react with the mismatched substrate DNA, it could be converted into amounts of output multiple-arm DNA junctions the M-CMDJA as the functional DNA conversion nanodevice.

The controversy of klotho as a potential biomarker in chronic kidney disease.

Klotho is an identified longevity gene with beneficial pleiotropic effects on the kidney. Evidence shows that a decline in serum Klotho level occurs in early chronic kidney disease (CKD) and continues as CKD progresses. Klotho deficiency is associated with poor clinical outcomes and CKD mineral bone disorders (CKD-MBD).

Network pharmacological investigation into the mechanism of Kaixinsan powder for the treatment of depression.

Kaixinsan powder (KXS), a classic prescription of traditional Chinese Medicine (TCM), is widely used in the treatment of depression, but its mechanism remains unclear. The network pharmacology method was used to constructe the "herb-component-target" network, and elucidated KXS potential mechanisms of action in the treatment of depression. Moreover, molecular docking was applied to valid the important interactions between the ingredients and the target protein.

Diosgenin exerts an antihypertensive effect in spontaneously hypertensive rats gut-brain communication.

Gut microbiota is well-established to regulate host blood pressure. Diosgenin is a natural steroid sapogenin with documented anti-inflammatory, antioxidant and antihypertensive properties. We aimed to investigate whether the antihypertensive effects of diosgenin are mediated by the microbiota-gut-brain axis in spontaneously hypertensive rats (SHR).

Predictors of rapid eye movement sleep behavior disorder in patients with Parkinson's disease based on random forest and decision tree.
