Synthesis and application of gelatin-based controlled-release antibacterial films containing oregano essential oil/β-cyclodextrin microcapsules for chilling preservation of grass carp fillets.

This work aimed to synthesize oregano essential oil/β-cyclodextrin microcapsules (OEO/β-CDs) and then prepare gelatin-based controlled-release antibacterial films with different OEO/β-CDs contents (0%-2%) for chilling preservation of grass carp fillets. The results of FTIR, XRD, DSC and accelerated release ratio showed that OEO was successfully encapsulated in OEO/β-CDs and its thermal stability was effectively improved. Moreover, at 2% of addition amount of OEO/β-CDs, the tensile strength of the films increased from 14.

Seasonal characteristics of groundwater discharge controlled by precipitation and its environmental effects in a coal mining subsidence lake, eastern China.

Many regions have formed subsidence lakes due to underground mining in the world. However, seasonal variations of lacustrine groundwater discharge (LGD) rate and solute fluxes in the coal mining subsidence were rarely reported. In this study, we conducted four seasonal samplings in a coal mining subsidence, during which samples for stable water (δO) and radioactive (Rn) isotopes were collected to quantify the seasonal dynamics of LGD rates.

Geochemical characteristics and migration patterns of rare earth elements in coal mining subsidence lakes under the influence of multiple factors.

Mining activities cause surface subsidence and the formation of subsidence lakes, which dynamically change with the continuous coal mining activities. Under the combined influence of various human activities such as agriculture, aquaculture, and floating photovoltaic (FPV), the lake environment undergoes continuous changes, thereby altering the geochemical characteristics of rare earth elements (REEs) in the sediment. This study focused on the subsidence lakes in the Huainan coalfield in eastern China to examine the REEs content in the sediment, elucidated the temporal variations and geochemical characteristics of REEs distribution, explored the main controlling factors of REEs in the sediment, and revealed the migration and transformation behavior of REEs during dynamic subsidence processes.

Water chemistry and stable isotope characteristics of subsidence lakes in coal mining areas, Eastern China.

Many subsidence lakes have formed in eastern China as a result of underground coal mining. These coal mining-related subsidence lakes vary in their formation time and connectivity with rivers. These factors may influence the water chemistry and hydrogen and oxygen stable isotope characteristics of the lake water.

Metabolic Profiling Revealed Prediction Biomarkers for Infantile Hemangioma in Umbilical Cord Blood Sera: A Prospective Study.

Infantile hemangioma (IH), the most common benign tumor in infancy, mostly arises and has rapid growth before 3 months of age. Because irreversible skin changes occur in the early proliferative stage, early medical treatment is essential to reduce the permanent sequelae caused by IH. Yet there are still no early screening biomarkers for IH before its visible emergence.

Aesthetic outcome of intralesional injection of lauromacrogol as a single-agent treatment for uncomplicated infantile hemangiomas: A long-term follow-up study.

Infantile hemangiomas (IH) are at risk of incomplete regression with remnant permanent sequelae, ranging from passive waiting for spontaneous regression to active systemic administration. The application of traditional therapy involving injection of a sclerosing agent is limited due to the difficulty in achieving cosmetic improvement. This study aimed to explore a new injection method that could not only promote tumor regression but also achieve cosmetic improvement.

Induction of telomere-mediated chromosomal truncation and behavior of truncated chromosomes in Brassica napus.

Engineered minichromosomes could be stably inherited and serve as a platform for simultaneously transferring and stably expressing multiple genes. Chromosomal truncation mediated by repeats of telomeric sequences is a promising approach for the generation of minichromosomes. In the present work, direct repetitive sequences of Arabidopsis telomere were used to study telomere-mediated truncation of chromosomes in Brassica napus.

The pigment epithelium-derived factor (PEDF): an important potential therapeutic agent for infantile hemangioma.

In previous studies, the expression and the role of proangiogenic factors in infantile hemangiomas have been well studied. However, the role of angiogenic inhibitors has been revealed rarely. The expression of PEDF, as the strongest and safe endogenous inhibitor, is still unrecognized until the current study.

Removal of dissolved sulfides in aqueous solution by activated sludge: mechanism and characteristics.

Activated sludge recycling has been developed as a novel technique to directly prevent volatile sulfides emission from wastewater influents. In this study, mechanisms and characteristics of dissolved sulfides removal in aqueous solution by activated sludge were investigated. When DO content in water was 0.

Rapid Identification of Candidate Genes for Seed Weight Using the SLAF-Seq Method in Brassica napus.

Seed weight is a critical and direct trait for oilseed crop seed yield. Understanding its genetic mechanism is of great importance for yield improvement in Brassica napus breeding. Two hundred and fifty doubled haploid lines derived by microspore culture were developed from a cross between a large-seed line G-42 and a small-seed line 7-9.

Inhibition or promotion of biodegradation of nitrate by Paracoccus sp. in the presence of nanoscale zero-valent iron.

To investigate the effect of nanoscale zero-valent iron (nZVI) on the growth of Paracoccus sp. strain and biodenitrification under aerobic conditions, specific factors were studied, pH, concentration of nitrate, Fe (II) and carbon dioxide. Low concentration of nZVI (50mg/L) promoted both cell growth and biodegradation of nitrate which rose from 69.

Angiogenin: a potential serum marker of infantile hemangioma revealed by cDNA microarray analysis.

Background: Hemangiomas are characterized by rapid growth but slow regression. Prognosis and treatment urgently require the identification of serum markers to determine the proliferative potential of hemangiomas.

Methods: Using four pairs of tissue from the proliferative and involution stages of the same hemangiomas, the authors performed cDNA microarray experiments to study differential expression of genes between proliferative hemangiomas and involuting hemangiomas.

Impact of iron-based nanoparticles on microbial denitrification by Paracoccus sp. strain YF1.

This study investigates the effects of Fe and Fe/Ni nanoparticles on biological denitrification when using Paracoccus sp. strain YF1. Results show that adding Fe and Fe/Ni nanoparticles to the cells decreased their growth and denitrification rate.

[Transposition of orbital fat and orbicularis muscle flap over the orbital rim for correction of lower eyelid pouches complicated with lacrimal groove deformity].

Objective: To introduce the experience in the treatment of lower eyelid pouches orbital rim.

Methods: An incision was made along the margin of lower eyelid and dissection was performed under the orbicularis muscle to expose the orbital septum and periosteum of lower orbital rim. The fat released from orbital septum was transposed just below the lower orbital rim and fixed on the periosteum.

Transcriptome profile analysis of young floral buds of fertile and sterile plants from the self-pollinated offspring of the hybrid between novel restorer line NR1 and Nsa CMS line in Brassica napus.

Background: The fertile and sterile plants were derived from the self-pollinated offspring of the F1 hybrid between the novel restorer line NR1 and the Nsa CMS line in Brassica napus. To elucidate gene expression and regulation caused by the A and C subgenomes of B. napus, as well as the alien chromosome and cytoplasm from Sinapis arvensis during the development of young floral buds, we performed a genome-wide high-throughput transcriptomic sequencing for young floral buds of sterile and fertile plants.

A prospective self-controlled phase II study of imiquimod 5% cream in the treatment of infantile hemangioma.

Imiquimod has been reported to be efficacious in the topical treatment of uncomplicated infantile hemangiomas (IH). However, due to the natural tendency of IH to involute spontaneously, prior uncontrolled efficacy and safety studies have been called into question. We conducted a prospective self-controlled phase II study of imiquimod initially applied to uncomplicated, proliferative superficial or mixed IHs treating half of each IH once every other night for 16 weeks, leaving the other half untreated.
