Effect of carboxymethyl chitosan on the storage stability of rice dough during frozen storage.

In this study, we aimed to determine the effect of carboxymethyl chitosan (CMCh) and carboxymethyl cellulose sodium (CMCNa) on the quality of frozen rice dough. We used a variety of methods to conduct a thorough investigation of frozen rice dough, including nuclear magnetic resonance (NMR), scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, size exclusion high-performance liquid chromatography (SE-HPLC), X-ray diffraction (X-RD), differential scanning calorimetry (DSC), and rapid visco analyzer (RVA). Our findings showed that frozen storage caused significant damage to the texture of rice dough, and this damage was reduced by the inclusion of CMCh, which led to a gradual change in the orderly structure of proteins.

DNA methylation modulates epigenetic regulation in colorectal cancer diagnosis, prognosis and precision medicine.

Colorectal cancer (CRC) is a multifaceted disease influenced by the interplay of genetic and environmental factors. The clinical heterogeneity of CRC cannot be attributed exclusively to genetic diversity and environmental exposures, and epigenetic markers, especially DNA methylation, play a critical role as key molecular markers of cancer. This review compiles a comprehensive body of evidence underscoring the significant involvement of DNA methylation modifications in the pathogenesis of CRC.

Macroscopic on‑site quality evaluation of biopsy specimens to improve the diagnostic accuracy of endoscopic ultrasound‑guided fine needle aspiration using a 22‑gauge needle for solid lesions: A single‑center retrospective study.

The present study aimed to evaluate the clinical value of macroscopic on-site evaluation (MOSE) of solid masses by endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) using a standard 22-gauge needle and to explore the cut-off length of macroscopic visible core (MVC) required to obtain an accurate histopathological diagnosis. In total, 119 patients who satisfied the inclusion and exclusion criteria and underwent EUS-FNA were divided into conventional FNA and FNA combined with MOSE groups. In the MOSE group, the presence of MVC was examined and its total length measured, after which the pathological results of FNA were compared with the final diagnosis.

The enhanced expression of genes encoding diguanylate cyclases under cold stress contributes to the adhesion and biofilm formation of WS13.

is a special spoilage bacterium of seafood during cold storage, which is easy to form biofilm and bring serious hazard to the seafood quality. Life cycle of biofilm starts after bacterial adhesion, which is essential for the formation and development of biofilm. As a ubiquitous second messenger in bacteria, c-di-GMP regulates the conversion between bacterial planktonic state and biofilm state.

Treatment of Infertile Women with Unilateral Tubal Occlusion Diagnosed by Hysterosalpingography: The Role of Intrauterine Insemination.

The optimal assisted reproductive treatment strategy for infertile women with unilateral tubal obstruction remains uncertain. To investigate the role of intrauterine insemination (IUI) in the treatment of infertile women with unilateral tubal occlusion, the data of 148 couples were retrospectively collected and analyzed. Seventy-eight infertile women with unilateral occlusion diagnosed by hysterosalpingography (HSG) were categorized as the study group and 70 others with unexplained infertility as the control group.

Systematic variational method for statistical nonlinear state and parameter estimation.

In statistical data assimilation one evaluates the conditional expected values, conditioned on measurements, of interesting quantities on the path of a model through observation and prediction windows. This often requires working with very high dimensional integrals in the discrete time descriptions of the observations and model dynamics, which become functional integrals in the continuous-time limit. Two familiar methods for performing these integrals include (1) Monte Carlo calculations and (2) variational approximations using the method of Laplace plus perturbative corrections to the dominant contributions.
