REVIEW
Christina E Bailey, Alexander A Parikh
Angiogenesis plays a critical role in the growth, progression, and metastasis of numerous solid tumor types, and thus, antiangiogenic agents have been studied for many years as potential therapeutic agents. Many different antiangiogenic agents, including monoclonal antibodies and multi-targeted tyrosine kinase inhibitors (TKIs), have been approved for various oncology indications, and promising clinical activity has been demonstrated. However, some of these agents have also been associated with serious safety concerns...

Neutrophilic bronchiolitis is the primary lesion in asthma-affected horses. Neutrophils are key actors in host defense, migrating toward sites of inflammation and infection, where they act as early responder cells toward external insults. However, neutrophils can also mediate tissue damage in various non-infectious inflammatory processes. Within the airways, these cells likely contribute to bronchoconstriction, mucus hypersecretion, and pulmonary remodeling by releasing pro-inflammatory mediators, including the cytokines interleukin (IL)-8 and IL-17, neutrophil elastase, reactive oxygen species (ROS), and neutrophil extracellular traps (NETs)...

Chancroid is a sexually transmitted infection (STI) caused by the Gram-negative bacterium Haemophilus ducreyi The control of chancroid is difficult and the only current available treatment is antibiotic therapy; however, antibiotic resistance has been reported in endemic areas. Owing to recent outbreaks of STIs worldwide, it is important to keep searching for new treatment strategies and preventive measures. Here, we applied reverse vaccinology and subtractive genomic approaches for the in silico prediction of potential vaccine and drug targets against 28 strains of H...

CASE HISTORY: Anal warts were observed in heifers in two unrelated groups of animals. Heifers in one group developed visible warts 4 months after manual rectal examination and heifers in the other group developed warts 5 months after examination using a hand-held rectal ultrasound probe. CLINICAL FINDINGS: Large exophytic proliferative anal masses were observed in 5/15 (33%) heifers in one group and 13/149 (9%) heifers in the second group. Heifers in the second group were also noted to have similar masses on the underside of the tail at sites previously used for venepuncture and some of the heifers had skin warts...

Due to advances in neoadjuvant therapies and preoperative imaging modalities, joint-sparing resections have become appealing in bone tumor surgery. However, the intercalary reconstruction of metadiaphyseal bone defects of the femur and the tibia after juxta-articular tumor resection remains challenging. Both biological and prosthetic reconstructions have been used for joint-sparing resections, but little is known about the long-term outcome of these procedures. The authors reviewed a consecutive series of 64 patients treated with joint-sparing intercalary resection and reconstruction with bone grafts...

The ability of low pathogenic (LP) avian influenza viruses (AIV) of the subtypes H5 and H7 to mutate spontaneously to highly pathogenic (HP) variants is the main reason for their stringent control. On-the-spot evidence from the field of mutations in LPAIV to render the virus into nascent HP variants is scarce. Epidemiological investigations and molecular characterization of two spatiotemporally linked outbreaks caused by LP, and subsequently, HPAIV H7N7 in two-layer farms in Germany yielded such evidence. The outbreaks occurred within 45 days on farms 400 m apart...

The Botrytis cinerea VELVET complex regulates light-dependent development and virulence. The goal of this study was to identify common virulence defects of several VELVET mutants and to reveal their molecular basis. Growth, differentiation, physiology, gene expression and infection of fungal strains were analyzed, and quantitative comparisons of in planta transcriptomes and secretomes were performed. VELVET mutants showed reduced release of citric acid, the major acid secreted by the wild-type, whereas no significant role for oxalic acid was observed...

Tuberculosis is a chronic granulomatous lesion, which primarily has an affinity for the lungs. It can involve other sites like lymph nodes, kidney, oral cavity. Infection of the oral cavity by M. tuberculosis can be as a Primary infection or as a Secondary infection. Primary presentation of oral tuberculosis is in the form of the chronic non healing ulcer. A Primary infection or an Asymptomatic Secondary infection can impose a great diagnostic dilemma, as it may mimic neoplasia. Here we present a case of a 32-year-old asymptomatic female with secondary infection...

With the rapid spreading of resistance among common bacterial pathogens, bacterial infections, especially antibiotic-resistant bacterial infections, have drawn much attention worldwide. In light of this, nanoparticles, including metal and metal oxide nanoparticles, liposomes, polymersomes, and solid lipid nanoparticles, have been increasingly exploited as both efficient antimicrobials themselves or as delivery platforms to enhance the effectiveness of existing antibiotics. In addition to the emergence of widespread antibiotic resistance, of equal concern are implantable device-associated infections, which result from bacterial adhesion and subsequent biofilm formation at the site of implantation...

INTRODUCTION: Treatment of pacemaker (PM) device infections is challenging in pacemaker dependent patients. We propose a novel implantation strategy for this group of patients. METHODS: Patients who were PM dependent and were admitted with a PM infection received a combined procedure of LV epicardial implantation of a PM lead and subsequent extraction of the infected system. No temporary pacing wire was used and the PM generator was placed in the left flank. RESULTS: Between 2012 and 2015 we treated 16 patients who were PM dependent with a PM infection...

Nitrogen-fixing filamentous Frankia colonize the root tissues of its actinorhizal host Discaria trinervis via an exclusively intercellular pathway. Here we present studies aimed at uncovering mechanisms associated with this little-researched mode of root entry, and in particular the extent to which the host plant is an active partner during this process. Detailed characterization of the expression patterns of infection-associated actinorhizal host genes has provided valuable tools to identify intercellular infection sites, thus allowing in vivo confocal microscopic studies of the early stages of Frankia colonization...

REVIEW
Margherita Sisto, Sabrina Lisi, Domenico Ribatti
The link between inflammatory microenvironment and cancer emerged in the last years as a decisive factor in the induction of the pathological epithelial-mesenchymal transition (EMT). The EMT induces changes of cell states converting the epithelial cells to mesenchymal cells when this program is fully executed and EMT has emerged as a central driver of tumor malignancy. Cellular pathways activated by chronic inflammation brought about by chronic infections, by immune-mediated diseases, or by dysregulated wound healing at sites of repetitive tissue injury, constitute risk factors or initial cell transformation and for cancer progression...

A 4-year-old captive ringed seal (Pusa hispida) was treated with subcutaneous antibacterial injections for pus exuding wounds in the skin and associated blubber following a bite attack. Three months after the incident, the animal presented nystagmus and died the following day. At necropsy, there was a 25 × 18 × 25 mm well-delineated, opaque nodular mass in the lung, besides the skin ulcers and localized areas of discoloration in the blubber correlating with the bite wound and injection sites. Histopathology of the pulmonary mass demonstrated severe eosinophilic inflammatory infiltration among numerous intralesional fungal hyphae...

In response to infection, polymorphonuclear neutrophils (PMN) are recruited in the infectious sites, and employ three major strategies to fight against the microbes including phagocytosis, degranulation, and neutrophil extracellular traps (NETs). NETs are a meshwork of chromatin fibers mixed with granule-derived antimicrobial peptides and enzymes, which trap and kill the bacteria extracellularly. In this study, by using a mouse sepsis model, we identified a novel mechanism by which NETs induce macrophage (Mϕ) pyroptosis, a caspase-1-dependent regulated cell death...
