Exploring causal correlations between inflammatory cytokines and coronary heart disease: A Mendelian randomization study.

Coronary heart disease (CHD) is a global health concern, with inflammation significantly contributing to its pathogenesis. It is crucial to understand the relationship between inflammatory cytokines and CHD. This study investigates the causal correlations between circulating inflammatory cytokines and CHD using Mendelian randomization (MR), assessing both causative and resultant roles of these cytokines in CHD.

Blood metabolites mediate effects of breakfast skipping on heart failure via Mendelian randomization analysis.

Numerous observational studies have suggested a potential causal relationship between skipping breakfast and cardiovascular diseases, including heart failure (HF). However, these studies are susceptible to inherent confounders and the challenge of reverse causation, and the underlying metabolic factors are not yet clear. Therefore, our aim is to assess the causal impact of breakfast skipping on HF and the role of potential mediating metabolic products from a genetic perspective, by conducting Mendelian Randomization (MR) studies and mediation analysis.

Causal relationship between breakfast skipping and myocardial infarction: Two-sample Mendelian randomization.

While observational studies suggest a connection between skipping breakfast and myocardial infarction (MI), the causal nature of this relationship is unclear. This study aims to investigate the genetic causal relationships between breakfast skipping and MI through Mendelian randomization (MR). Employing genetic data from a public genome-wide association study, this research focuses on genetic variations linked to breakfast skipping and MI.

Effects of Different Feed Additives on Intestinal Metabolite Composition of Weaned Piglets.

To study the effects of different feed additives on the weaning stress of Tibetan piglets, we selected 28 healthy, 30-day-old Tibetan weaned piglets and divided them into four groups, namely, the control group (basal feed without any antibiotic additions) (Nor), the group with the addition of the antibiotic lincomycin (Ant), the group with the addition of fifteen-flavor black pills of Tibetan medicine (Tib), and the group with the addition of fecal bacterial supernatant (Fec). We measured growth performance, blood physiological indexes, and metabolomics. The results showed that the Ant, Tib, and Fec groups significantly reduced the ratio of diarrhea to feed/weight (F/G) and increased the average daily gain (ADG) compared with the Nor group ( < 0.

Effect of maternal dietary supplementation with phytosterol esters on muscle development of broiler offspring.

Recently, embryo muscle development, which is crucial for postnatal skeletal muscle growth, has been investigated widely. Nutrients in ovo were suggested to be critical in embryo muscle development since the chick growth mostly relies on nutrients in eggs at the early developmental stage. Phytosterol esters (PE), which are derived from the reactions between phytosterols and fatty acids, were demonstrated to have important effects on lipid and cholesterol metabolism regulation.

Dietary thymol supplementation promotes skeletal muscle fibre type switch in longissimus dorsi of finishing pigs.

As one of the key points related to meat quality, skeletal muscle fibre type is determined by energy metabolism and genetic factors, but its transformation could be also greatly influenced by many factors. Thymol, the primary effective ingredients of thyme, is well known for its anti-oxidation and anti-inflammatory, while little is known about its effect on skeletal muscle oxidative metabolism and fibre type switch. Therefore, in order to investigate its effects and possibility to be applied in livestock production, 36 150-day-old fattening Pigs were fed with different diet for six-week experiment.

Ca-Calcineurin-NFAT pathway mediates the effect of thymol on oxidative metabolism and fiber-type switch in skeletal muscle.

Thymol is a major component of thyme, and it has been reported that thymol administration reduces body weight, plasma insulin and blood glucose in type-2 diabetes. Skeletal muscle is the most important metabolism organs in the body; however, to date, there is no report on the effect of thymol on skeletal muscle. Our goal was to determine whether thymol has an effect on the different types of skeletal muscle fibers and their metabolism characteristics.

Succinate induces skeletal muscle fiber remodeling via SUNCR1 signaling.

The conversion of skeletal muscle fiber from fast twitch to slow-twitch is important for sustained and tonic contractile events, maintenance of energy homeostasis, and the alleviation of fatigue. Skeletal muscle remodeling is effectively induced by endurance or aerobic exercise, which also generates several tricarboxylic acid (TCA) cycle intermediates, including succinate. However, whether succinate regulates muscle fiber-type transitions remains unclear.

Lauric Acid Accelerates Glycolytic Muscle Fiber Formation through TLR4 Signaling.

Lauric acid (LA), which is the primary fatty acid in coconut oil, was reported to have many metabolic benefits. TLR4 is a common receptor of lipopolysaccharides and involved mainly in inflammation responses. Here, we focused on the effects of LA on skeletal muscle fiber types and metabolism.

Diversity effect of capsaicin on different types of skeletal muscle.

Capsaicin is a major pungent content in green and red peppers which are widely used as spice, and capsaicin may activate different receptors. To determine whether capsaicin has different effects on different types of skeletal muscle, we applied different concentrations (0, 0.01, and 0.

Phytol Promotes the Formation of Slow-Twitch Muscle Fibers through PGC-1α/miRNA but Not Mitochondria Oxidation.

Phytol is a side chain of chlorophyll belonging to the side-chain double terpenoid. When animals consume food rich in chlorophyll, phytol can be broken down to phytanic acid after digestion. It was reported that feeding animals with different varieties and levels of forage could significant improve pH and marbling score of steer and lamb carcasses, but the internal mechanism for this is still not reported.

[In vitro evaluation of cutaneous allergic reaction induced by chemicals using dendritic cells].

Objective: To investigate the use of dendritic cells derived from mice bone marrow to evaluate the cutaneous allergic reaction induced by chemical sensitizers.

Methods: Dendritic cells derived from mice bone marrow were cultured and administrated with 2, 4-dinitrochlorobenzene (DNCB), nickel sulfate (NiSO4), sodium dodecyl sulfate (SDS) and hexyl cinnamic aldehyde (HCA), respectively. Cell membrane molecule CD86 and extracellular IL-1 beta, IL-6 and IL-12 were detected after 0, 1, 6, 12, 24, 36, 48 hour's administration, respectively.
