Purpose: To evaluate the application value of 3D printing modified dental support cyst plug in fenestration of large jaw cystic lesions.
Methods: Forty patients with mandibular cystic disease in Xuzhou Central Hospital from October 2019 to April 2021 were selected. They were randomly divided into experimental group(3D printing group) and control group (traditional plug group), with 20 cases in each group.
The Betta fish displays a remarkable variety of phenotypes selected during domestication. However, the genetic basis underlying these traits remains largely unexplored. Here, we report a high-quality genome assembly and resequencing of 727 individuals representing diverse morphotypes of the Betta fish.

To investigate the regulation of genes of , 1,121-bp and 1,270-bp regions of the and promoters were cloned and analyzed, respectively. The two promoters shared partially conserved features and possessed distinct characteristics such as the number or position of metal response elements (MREs). Further analysis of the and promoters was performed by the reporter assay using the luciferase gene.

It lasted for 36 months and was divided into three main stages: initiation of gonad formation, a stable growth phase, and a reproductive cell development phase. Each reproductive cycle consisted of five stages: proliferative stage (from late January to late February), growth stage (from late February to late March), maturation stage, spawning stage (from early April to late October) and recovery stage (from early November to late January).

The open reading frame of HsMT1 and HsMT2 were 216 and 222 bp, encoding a protein of 71 and 73 amino acid residues. The deduced amino acid sequences showed they contained parts of typical MT characteristics, apart from HsMT2 lacked Cys-Cys motifs.

Here, for the first time we cloned the full-length cDNA sequence of Hyriopsis schlegelii (Hs-BTG1), an economically important freshwater shellfish and potential indicator of environmental heavy metal pollution, for the first time. Using rapid amplification of cDNA ends (RACE) together with splicing the EST sequence from a haemocyte cDNA liary, we found that Hs-BTG1 contains a 525 bp open reading frame (ORF) encoding a 174 amino-acid polypeptide, a 306 bp 5' untranslated region (5' UTR), and a 571 bp 3' UTR with a Poly(A) tail as well as a transcription termination signal (AATAAA).

In the present study, two distinct cDNAs for ferritins in the freshwater pearl mussel Hyriopsis schlegelii were identified (designated as HsFer-1 and HsFer-2) by SMART RACE approach and expressed sequence tag (EST) analysis. The full-length cDNAs of HsFer-1 and HsFer-2 were of 760 and 877 bp, respectively.

Distinct biomaterials have been shown to differentially affect the phenotype of DCs, which suggested that biomaterials may be used to modulate immune response toward the biologic component in combination products. The elucidation of biomaterial property-DC phenotype relationships is expected to inform rational design of immuno-modulatory biomaterials.

Macrophages (Mϕ) and dendritic cells (DCs) are critical antigen presenting cells that play pivotal roles in host responses to biomaterial implants. Although Mϕs have been widely studied for their roles in the inflammatory responses against biomaterials, the roles that DCs play in the host responses toward implanted materials have only recently been explored. DCs are of significant research interest because of the emergence of a large number of combination products that cross-traditional medical device boundaries.

The sensitivity of DCs to foreign stimuli also makes them useful cells to assess the inflammatory response to biomaterials. Elucidating material property-DC phenotype relationships using a well-defined biomaterial system is expected to provide criteria for immunomodulatory biomaterial design.

Background: Fetal alcohol spectrum disorder (FASD) is a challenging public health problem. Previous studies have found an association between FASD and oxidative stress. In the present study, we assessed the role of oxidative stress in ethanol-induced embryonic damage and the effect of (-)-epigallocatechin-3-gallate (EGCG), a powerful antioxidant extracted from green tea, on the development of FASD in a murine model.

View Article and Find Full Text PDFPorous silicon multilayer structures have remarkable optical and morphological properties that can be exploited for biosensing. In particular, a high internal surface area (>100 m(2)/cm(3)) and a linear response profile to changes in the dielectric environment enable fabrication of sensitive devices and a straightforward quantitation of the optical response. These essential operating characteristics are illustrated for p+ mesoporous silicon (pore diameter 15-20 nm) optical microcavities.
