Global, regional, and national epidemiology of ischemic heart disease among individuals aged 55 and above from 1990 to 2021: a cross-sectional study.

Background: The findings of the 2021 Global Burden of Disease (GBD) study can offer valuable insights for the development of screening and prevention strategies targeting ischemic heart disease (IHD). We aim to investigate trends in IHD incidence, mortality, and disability-adjusted life years (DALYs), while exploring associated risk factors for IHD-associated death from 1990 to 2021.

Methods: The cross-sectional study utilized data from the GBD 2021, covering 204 countries and regions.

How does bivalve size influence microplastics accumulation?

Microplastics (wasted plastic particles < 5 mm in diameter) are ubiquitously distributed in the marine environment. Filter-feeding and low trophic level bivalves are vulnerable to microplastics accumulation from the surrounding depositional environment, thereby threatening both ecological health and human food safety. Microplastics had been detected in lots of coastal Bivalvia species.

Extraction, structural characterization, and antioxidant and immunomodulatory activities of a polysaccharide from Notarchus leachii freeri eggs.

The crude polysaccharides (NLCEP) were extracted from Notarchus leachii freeri eggs strings by the saltextractionmethod. The extraction conditions were optimized using the single-factorexperimentmethod and response surface method (RSM). The results showed that the maximum extraction yield of NLCEP was obtained under the following conditions: NaCl solution concentration of 2.

A comprehensive evaluation of the potential of semiterrestrial isopods, Ligia exotica, as a new animal food.

The semiterrestrial isopod, Ligia exotica represents one of the oldest documented species introductions of marine organisms and is known as an intermediate form between marine and strictly terrestrial isopods. In order to explore the potential value of Ligia as an animal food source, this study focused on the growth rate under laboratory rearing conditions and conducted a detailed analysis of the overall nutrient content of the species in comparison to two other marine food media (krill and fish meal). Evaluation of the growth rate of juveniles suggests it is a relatively fast-growing species of the Ligiidae family.

De novo transcriptome sequencing and analysis of the cuttlefish () with different embryonic developmental stages.

In this study, embryos of from eye primordium formation to the larval growing stage were collected and used for RNA-Seq analysis. A total of 183,542,186 clean reads were assembled de novo into 58,054 unigenes consisting of 54,118,228 bp, with the average length at 932 bp and the N50 at 1667 bp. 21,469 (36.

Astragaloside IV exerts angiogenesis and cardioprotection after myocardial infarction via regulating PTEN/PI3K/Akt signaling pathway.

Aims And Methods: Acute myocardial infarction (AMI) is a common cardiovascular disease with high mortality. Astragaloside IV (AS-IV) was reported to have cardioprotective effect after AMI. We hypothesize that the cardioprotective role of AS-IV is exerted by enhancing angiogenesis via regulating PTEN/PI3K/Akt signaling pathway.

A transcriptome resource for pharaoh cuttlefish (Sepia pharaonis) after ink ejection by brief pressing.

Ink ejection is one of the most important defense mechanisms against external stimuli for pharaoh cuttlefish (Sepia pharaonis). The molecular changes during this process remain unknown. To understand the transcriptome changes after ink ejection by brief pressing, two cDNA libraries of pharaoh cuttlefish, from the inkjet group and control group were sequenced using Illumina HiSeq™ 2000.

Effects of chitin and sepia ink hybrid sponge on the healing of burning wound rats and its impact on macrophages in vitro.

Purpose: To detect whether chitin and sepia ink sponge (CS) can promote wound healing and elevate impact of CS on phagocytosis ability of macrophages.

Methods: Forty-eight rats were assigned to four groups: Normal group (Normal), negative control group (Con), chitin and sepia ink sponge group (CS) and positive control Surgicel Gauze(r) group (SG). Deep second-degree burn model was created in rats.

Effects of chitin and sepia ink hybrid hemostatic sponge on the blood parameters of mice.

Chitin and sepia ink hybrid hemostatic sponge (CTSH sponge), a new biomedical material, was extensively studied for its beneficial biological properties of hemostasis and stimulation of healing. However, studies examining the safety of CTSH sponge in the blood system are lacking. This experiment aimed to examine whether CTSH sponge has negative effect on blood systems of mice, which were treated with a dosage of CTSH sponge (135 mg/kg) through a laparotomy.
