Global research hotspots and trends of the vaccines: Based on ESI hot papers.

The aim of this study was to determine the characteristics of the Essential Science Indicators (ESI) hot papers on vaccine research and to provide a summary of the hot spots and development trends in the field. A systematic and comprehensive search for literature on vaccine research was conducted in the Web of Science Core Collection, and 81 ESI hot papers were obtained. A total of 81 ESI Hot Papers from 51 journals were identified in the domain of vaccines, of which 93.

A new insight into the mechanism of cadmium-induced nephrotoxicity and antagonism of selenium nanoparticles: modulation of MTF1-MT axis dependent metal homeostasis.

Cadmium (Cd) is a highly toxic pollutant that causes direct harm to the kidney. Cellular metal homeostasis is one of the key targets of heavy metal toxicity and may represent an alleviation pathway for environmentally-related kidney disease. Selenium nanoparticles (SeNPs) is a antioxidant and is considered to be involved in the regulation of cellular metal transport.

Global vaccine research and application hotspots and trends: a systematic bibliometric analysis based on SCIE highly cited papers.

Objectives: COVID-19, a public health emergency affecting the world in 2019, not only greatly promoted the development and application of vaccines but also effectively shortened the publishing time of scientific papers. In view of these facts, the current situation, status, problems and development trends of vaccine research and application were explored through bibliometric analysis of highly cited papers in the vaccine field within the time frame of 2014-2024, and the countries, institutions, authors, funding agencies and other relevant information that contributed most to vaccine research and application were summarised.

Design: Bibliometric analysis through data analysis and visual mapping.

The relationship between late (≥ 7 days) systemic dexamethasone and functional network connectivity in very preterm infants.

Background: Current evidence shows that systemic dexamethasone administration starting after the first week of age reduces bronchopulmonary dysplasia for very preterm (VPT) infants, but its neurological effects remain obscure. Using resting-state functional magnetic resonance imaging (rs-fMRI), we assessed the changes in functional network connectivity (FNC) in very preterm infants treated with late systemic dexamethasone (7 days of age).

Methods: VPT infants (GA ≤ 32 weeks) who needed to rely on mechanical ventilation for more than 7 days but fewer than 14 days to maintain vital signs were included in the study.

Occlusion as a predisposing factor for peri-implant disease: A review article.

Background: The restoration of dental implants presents a unique challenge due to the intrinsic biomechanical differences between osseointegrated implants and natural teeth, and their subsequent responses to occlusal loading. However, controversy exists regarding the role that occlusion plays in the physiology of the peri-implant complex.

Purpose: To provide an overview of the scientific literature regarding occlusion as it relates to implant dentistry and peri-implant disease.

Study of a Mode Separation Due to Polarization Existing in a Cavity-Enhanced Absorption Spectroscopy.

A special phenomenon of resonance mode separation is observed during the study of a high sensitivity folded-cavity enhanced absorption spectroscopy for the measurement of trace gases. The phenomenon affects the measurement of gas absorption spectrum in the cavity. This resonant mode separation phenomenon of the resonant cavity is different from the resonant modes previously observed in linear-cavity enhanced absorption spectroscopy systems.

Diversity of Extended-Spectrum Cephalosporin-Resistant in Feces from Calves and Cows on Pennsylvania Dairy Farms.

The global incidence of human infections associated with extended-spectrum β-lactamase (ESBL)-producing is increasing. Dairy animals are reservoirs of ESBL-producing , especially, third-generation cephalosporin (3GC)-resistant strains. To further understand the diversity of 3GC-resistant across animals of different age groups (e.

Antimicrobial Resistance Among Escherichia coli Isolated from Veal Calf Operations in Pennsylvania.

Antimicrobial resistance (AR) is a pressing public health concern, and agricultural operations such as dairy and beef cattle production have been implicated as potential sources of resistant bacteria or genetic elements. This study aimed to determine the prevalence of antimicrobial-resistant Escherichia coli from calf pens in 6 auction houses (56 manure composite samples) and 12 veal calf operations (240 fecal samples in 2 visits: after the calves arrived at the farm and shortly before the animals were sent to slaughter) in the Commonwealth of Pennsylvania. A total of 1567 generic E.

Age-Associated Distribution of Antimicrobial-Resistant Salmonella enterica and Escherichia coli Isolated from Dairy Herds in Pennsylvania, 2013-2015.

Antimicrobial resistance has become a major global public health concern, and agricultural operations are often implicated as a source of resistant bacteria. This study characterized the prevalence of antimicrobial-resistant Salmonella enterica and Escherichia coli from a total of 443 manure composite samples from preweaned calves, postweaned calves, dry cows, and lactating cows from 80 dairy operations in Pennsylvania. A total of 1095 S.

Modeling the long-term kinetics of Salmonella survival on dry pet food.

Due to multiple outbreaks and large-scale product recalls, Salmonella has emerged as a priority pathogen in dry pet food and treats. However, little data are available to quantify risks posed by these classes of products to both pets and their owners. Specifically, the kinetics of Salmonella survival on complex pet food matrices are not available.

Dynamics of Escherichia coli Virulence Factors in Dairy Herds and Farm Environments in a Longitudinal Study in the United States.

Pathogenic Escherichia coli or its associated virulence factors have been frequently detected in dairy cow manure, milk, and dairy farm environments. However, it is unclear what the long-term dynamics of E. coli virulence factors are and which farm compartments act as reservoirs.

Enhancement effect of ultrasound-induced microbubble cavitation on branched polyethylenimine-mediated VEGF(165) transfection with varied N/P ratio.

One isoform of the vascular endothelial growth factor, VEGF(165), has been reported to be a dominant mediator and regulator of angiogenic process, which plays an important role in treating cardiovascular diseases and chronically ischemic wounds. Branched polyethylenimine (bPEI) has been widely used as a non-viral delivery vector for gene therapy. Although bPEI-mediated DNA transfection efficiency can be raised by increasing the PEI nitrogen:DNA phosphate (N/P) ratio, cytotoxicity increases as well.

[Efficacy of recombinant hepatitis B vaccine and low-dose hepatitis B immune globulin in preventing mother-infant transmission of hepatitis B virus infection].

Background: To determine the long-term efficacy and persistence of Chinese infants after receiving only active plasma-derived hepatitis B vaccine, and to evaluate if providing booster vaccination after basic hepatitis B immunization is necessary.

Methods: Infants who were born in 1986-1988 in four demonstrative hepatitis B immunization trial areas of Hunan, Guangxi, Hebei and Shanghai after receiving only active plasma-derived hepatitis B vaccination, had been randomly followed up for 15 years. HBsAg,anti-HBs and anti-HBc in 21 680 person-times were tested using commercial SPRIA kits.
