Comparative Genomic Analysis of Bacterial Data in BV-BRC: An Example Exploring Antimicrobial Resistance.

As genomic and related data continue to expand, research biologists are often hampered by the computational hurdles required to analyze their data. The National Institute of Allergy and Infectious Diseases (NIAID) established the Bioinformatics Resource Centers (BRC) to assist researchers with their analysis of genome sequence and other omics-related data. Recently, the PAThosystems Resource Integration Center (PATRIC), the Influenza Research Database (IRD), and the Virus Pathogen Database and Analysis Resource (ViPR) BRCs merged to form the Bacterial and Viral Bioinformatics Resource Center (BV-BRC) at https://www.

Introducing the Bacterial and Viral Bioinformatics Resource Center (BV-BRC): a resource combining PATRIC, IRD and ViPR.

The National Institute of Allergy and Infectious Diseases (NIAID) established the Bioinformatics Resource Center (BRC) program to assist researchers with analyzing the growing body of genome sequence and other omics-related data. In this report, we describe the merger of the PAThosystems Resource Integration Center (PATRIC), the Influenza Research Database (IRD) and the Virus Pathogen Database and Analysis Resource (ViPR) BRCs to form the Bacterial and Viral Bioinformatics Resource Center (BV-BRC) https://www.bv-brc.

A genomic data resource for predicting antimicrobial resistance from laboratory-derived antimicrobial susceptibility phenotypes.

Antimicrobial resistance (AMR) is a major global health threat that affects millions of people each year. Funding agencies worldwide and the global research community have expended considerable capital and effort tracking the evolution and spread of AMR by isolating and sequencing bacterial strains and performing antimicrobial susceptibility testing (AST). For the last several years, we have been capturing these efforts by curating data from the literature and data resources and building a set of assembled bacterial genome sequences that are paired with laboratory-derived AST data.

Immunohistochemical Femoral Nerve Study Following Bisphosphonates Administration.

Bisphosphonates represent selective inhibitors of excess osteoblastic bone resorption that characterizes all osteopathies, targeting osteoclasts and their precursors. Their long-term administration in postmenopausal women suffering from osteoporosis has resulted in neural adverse effects. The current study focuses on the research of possible alterations in the femoral nerve, caused by bisphosphonates.

Bisphosphonate's Effect on Tongue Mucosa: An Experimental Electron Microscopy Study.

Background And Objectives: Bisphosphonates (BPs) are selective inhibitors of osteoclasts, used for the treatment of bone disorders. The objective of this study is to investigate the possible effects of BPs on the tongue's mucosa.

Materials And Methods: Specimens of the tongue of 20 female 12-month old Wistar rats were taken.

The PATRIC Bioinformatics Resource Center: expanding data and analysis capabilities.

The PathoSystems Resource Integration Center (PATRIC) is the bacterial Bioinformatics Resource Center funded by the National Institute of Allergy and Infectious Diseases (https://www.patricbrc.org).

Alendronate effect in esophagus, stomach and liver: an animal based pathological study.

Bisphosphonates are commonly used in clinical practice. Their effectiveness is indisputable, however their adverse effects, especially in the GI tract, are still controversial. In our report, we demonstrate pathological findings of the effect of systematic alendronate administration in esophagus, stomach and the liver of an in-vivo animal model of 15 Wistar rats.

Antiseptic negative pressure instillation therapy for the treatment of septic wound healing deficits in oral and maxillofacial surgery.

Introduction: Impaired wound healing, chronic wounds and extended soft tissue defects present a crucial problem in reconstructive surgery of the head and neck region, even more after radiation therapy. In such cases the standard is a prolonged open wound treatment. The negative pressure instillation therapy might present an alternative therapy option.

PATRIC as a unique resource for studying antimicrobial resistance.

The Pathosystems Resource Integration Center (PATRIC, www.patricbrc.org) is designed to provide researchers with the tools and services that they need to perform genomic and other 'omic' data analyses.

Consultation with a specialized pain clinic reduces pain after oral and maxillofacial surgery.

Purpose: Postoperative pain management is important for improved patient care. Our primary objective was to investigate the effect of analgesic treatment adaptation by the pain clinic on postoperative pain relief at an oral and maxillofacial surgery department. Additionally, we aimed to present patients' pain characteristics and the administered analgesic treatment.

Ultrastructural aspects of the effects of L-carnitine administration on epithelial cells in the aging rat tongue.

Background: The investigators hypothesized that degenerative changes accumulate in epithelial cells in the aging rat tongue and that carnitine administration is effective at reversing these alterations.

Material And Methods: To gain insights into the effects of carnitine on epithelial cells of the tongue, the investigators used 15 Wistar rats [3 experimental groups: 5- (A), 12- (B) and 18- (C) month old rats] with 4 rats per group and 1 control group with 1 rat per age group). L-carnitine was administered intraperitoneally to animals of the experimental group for 35 days.

Is copper chelation an effective anti-angiogenic strategy for cancer treatment?

Angiogenesis and the acquisition of an angiogenic phenotype is important for cancer cell proliferation. Copper in an essential trace element that participates in many enzymatic complexes like the cytochrome c, superoxide dismutase and lysyl oxidase and it is involved in processes, like embryogenesis, growth, angiogenesis and carcinogenesis. In particular, its involvement in carcinogenesis was described for the first time in oral submucous fibrosis, where fibroblasts produce large amounts of collagen in the presence of copper.

Molecularly targeted drugs for the treatment of cancer: oral complications and pathophysiology.

Background: Targeted cancer therapy is a new approach for the treatment of cancer. It involves a specific molecular target, mainly a receptor that serves as a target for monoclonal antibodies or tyrosine kinase inhibitors. Side-effects of these new regimens are described to be mild, compared to those of classical chemotherapy.

Bone-vasculature interactions in the mandible: is bone an angiogenic tissue?

Starting from early stages of craniofacial development, the leading role of vasculature, in particular endothelial progenitor cells, becomes apparent. They are probably the cells that synthesize the appropriate bone morphogenetic protein (BMP), that precedes neural crest cell migration and determines their final destination and skeletal development. During postnatal osteosynthesis in the mandible, angiogenesis similarly goes before osteosynthesis, regulates this process with the production of BMP-2 and serves as a scaffold for osteoblasts.

Sublingual-plunging ranula as a complication of supraomohyoid neck dissection.

Ranulas are rare cystic lesions resulting from damage or rupture of one or more of the ducts of the sublingual gland, that lead to mucus extravasation or dilatation of the gland's duct. Extravasation cysts are more common than retention cysts. We present a case of a 45-year-old male with a squamous cell carcinoma of the ventral surface of the tongue that was treated with excision of the oral lesion and bilateral supraomohyoid neck dissection without supplementary radiotherapy.

Odontogenic fibromyxoma of the maxilla: a case report and review of the literature.

Fibromyxoma represents a rare benign neoplasm that mostly affects the posterior region of the mandible. Here, we report the case of a 46-year-old male with a swelling of the right maxilla. After proper diagnosis, he was treated with enucleation and curettage of the tumor.

Leaf palmate venation and vascular redundancy confer tolerance of hydraulic disruption.

Leaf venation is a showcase of plant diversity, ranging from the grid-like network in grasses, to a wide variety of dendritic systems in other angiosperms. A principal function of the venation is to deliver water; however, a hydraulic significance has never been demonstrated for contrasting major venation architectures, including the most basic dichotomy, "pinnate" and "palmate" systems. We hypothesized that vascular redundancy confers tolerance of vein breakage such as would occur during mechanical or insect damage.
