How did investigations into spontaneous human combustion influence alcohol medicine? An examination of the medical and literary discussions that brought the two together.

Background And Aims: The presence of sections or chapters on spontaneous human combustion in more than half of the key texts in English on the action of alcohol on the body and mind in the first half of the nineteenth century demonstrates the seriousness with which it was considered. We aimed to chart discussions about the links between spontaneous human combustion and spirit drinking in medical texts and representations in fiction through three key chronological periods from 1804 to 1900.

Methods: A contextual analysis using eighteenth- and nineteenth-century historical, literary and medical sources to chart and reflect on public and medical discourses.

Syntheses, Structures and Reactivity of Metal Complexes of Trindane, Trindene, Truxene, Decacyclene and Related Ring Systems: Manifestations of Three-Fold Symmetry.

The triple condensation of cyclopentanone or indanone to trindane (CH) or truxene (CH), respectively, provides convenient access to molecular skeletons on which major fragments of the prototypical fullerene C can be assembled. In particular, early approaches (both organic and organometallic) towards sumanene, as well as the final successful synthesis, are described. Organometallic derivatives of trindane have been prepared in which Cr(CO), Mo(CO), [Mn(CO)] or [(CH)Fe(CO)] are η-bonded to the central arene ring.

Annexin A1 Is Required for Efficient Tumor Initiation and Cancer Stem Cell Maintenance in a Model of Human Breast Cancer.

Triple-negative breast cancer (TNBC) has a poor outcome compared to other breast cancer subtypes, and new therapies that target the molecular alterations driving tumor progression are needed. Annexin A1 is an abundant multi-functional Ca binding and membrane-associated protein. Reported roles of Annexin A1 in breast cancer progression and metastasis are contradictory.

A switch in mechanism of action prevents doxorubicin-mediated cardiac damage.

Cancer patients treated with doxorubicin are at risk of congestive heart failure due to doxorubicin-mediated cardiotoxicity via topoisomerase IIβ poisoning. Acute cardiac muscle damage occurs in response to the very first dose of doxorubicin, however, cardioprotection has been reported after co-treatment of doxorubicin with acyloxyalkyl ester prodrugs. The aim of this study was to examine the role played by various forms of acute cardiac damage mediated by doxorubicin and determine a mechanism for the cardioprotective effect of formaldehyde-releasing prodrug AN-9 (pivaloyloxymethyl butyrate).

Novel Bacteriophages Capable of Disrupting Biofilms From Clinical Strains of .

The increase in global warming has favored growth of a range of opportunistic environmental bacteria and allowed some of these to become more pathogenic to humans. is one such organism. Surviving in moist conditions in temperate climates, these bacteria have been associated with a range of diseases in humans, and in systemic infections can cause mortality in up to 46% of cases.

FGF13 promotes metastasis of triple-negative breast cancer.

Triple-negative breast cancer (TNBC) represents 10-20% of all human ductal adenocarcinomas and has a poor prognosis relative to other subtypes, due to the high propensity to develop distant metastases. Hence, new molecular targets for therapeutic intervention are needed for TNBC. We recently conducted a rigorous phenotypic and genomic characterization of four isogenic populations of MDA-MB-231 human triple-negative breast cancer cells that possess a range of intrinsic spontaneous metastatic capacities in vivo, ranging from nonmetastatic (MDA-MB-231_ATCC) to highly metastatic to lung, liver, spleen and spine (MDA-MB-231_HM).

Correction to: Defining the role of cytoskeletal components in the formation of apoptopodia and apoptotic bodies during apoptosis.

The original version of the article unfortunately contained a typo in the fourth author name. The author name was incorrectly listed as Rochelle Tixeria. The correct name should be Rochelle Tixeira.

Defining the role of cytoskeletal components in the formation of apoptopodia and apoptotic bodies during apoptosis.

During apoptosis, dying cells undergo dynamic morphological changes that ultimately lead to their disassembly into fragments called apoptotic bodies (ApoBDs). Reorganisation of the cytoskeletal structures is key in driving various apoptotic morphologies, including the loss of cell adhesion and membrane bleb formation. However, whether cytoskeletal components are also involved in morphological changes that occur later during apoptosis, such as the recently described generation of thin apoptotic membrane protrusions called apoptopodia and subsequent ApoBD formation, is not well defined.

Extracellular vesicles secreted by are involved in cell wall remodelling.

Extracellular vesicles (EVs) are membranous vesicles that are released by cells. In this study, the role of the Endosomal Sorting Complex Required for Transport (ESCRT) machinery in the biogenesis of yeast EVs was examined. Knockout of components of the ESCRT machinery altered the morphology and size of EVs as well as decreased the abundance of EVs.

Genomic, morphological and functional characterisation of novel bacteriophage FNU1 capable of disrupting Fusobacterium nucleatum biofilms.

Fusobacterium nucleatum is an important oral bacterium that has been linked to the development of chronic diseases such as periodontitis and colorectal cancer. In periodontal disease, F. nucleatum forms the backbone of the polymicrobial biofilm and in colorectal cancer is implicated in aetiology, metastasis and chemotherapy resistance.

Memory regulatory T cells home to the lung and control influenza A virus infection.

Memory regulatory T cells (mTregs) have been demonstrated to persist long-term in hosts after the resolution of primary influenza A virus (IAV) infection. However, whether such IAV infection-experienced (IAV-experienced) mTregs differentiate into a phenotypically and functionally distinct Treg subset and what function they play at the infection site remains poorly defined. In this study, we characterized the phenotype, examined the responsiveness and assessed the suppressive function of IAV-experienced memory Tregs (mTregs).

Anterior maxillary wall and lacrimal duct relationship in Orientals: CT analysis for prelacrimal access to the maxillary sinus.

Background: The pre-lacrimal window approach (PLWA) is a promising technique in approaching lesions of the anterior wall and floor of the maxillary sinus. Simmen et al. previously reported that this approach is feasible in only 2/3 of their patients.

Isolation and characterization of bacteriophage NTR1 infectious for Nocardia transvalensis and other Nocardia species.

We describe here the isolation and characterization of the bacteriophage, NTR1 from activated sludge. This phage is lytic for Nocardia transvalensis, Nocardia brasiliensis and Nocardia farcinica. NTR1 phage has a genome sequence of 65,275 bp in length, and its closest match is to the Skermania piniformis phage SPI1 sharing over 36% of its genome.

Confocal Microscopy Reveals Cell Surface Receptor Aggregation Through Image Correlation Spectroscopy.

Confocal microscopy provides an accessible methodology to capture sub-cellular interactions critical for the characterization and further development of pre-clinical agents labeled with fluorescent probes. With recent advancements in antibody based cytotoxic drug delivery systems, understanding the alterations induced by these agents within the realm of receptor aggregation and internalization is of critical importance. This protocol leverages the well-established methodology of fluorescent immunocytochemistry and the open source FIJI distribution of ImageJ, with its inbuilt autocorrelation and image mathematical functions, to perform spatial image correlation spectroscopy (ICS).

Functional and genomic characterisation of a xenograft model system for the study of metastasis in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) represents 10-20% of all human ductal adenocarcinomas and has a poor prognosis relative to other subtypes. Hence, new molecular targets for therapeutic intervention are necessary. Analyses of panels of human or mouse cancer lines derived from the same individual that differ in their cellular phenotypes but not in genetic background have been instrumental in defining the molecular players that drive the various hallmarks of cancer.

Molecular characterization of the first saltwater crocodilepox virus genome sequences from the world's largest living member of the Crocodylia.

Crocodilepox virus is a large dsDNA virus belonging to the genus Crocodylidpoxvirus, which infects a wide range of host species in the order Crocodylia worldwide. Here, we present genome sequences for a novel saltwater crocodilepox virus, with two subtypes (SwCRV-1 and -2), isolated from the Australian saltwater crocodile. Affected belly skins of juvenile saltwater crocodiles were used to sequence complete viral genomes, and perform electron microscopic analysis that visualized immature and mature virions.

Aim: To isolate and characterize bacteriophage lytic for the opportunistic pathogen Klebsiella oxytoca and their formulation into a range of solid dosage forms for in-vitro testing.

Methods And Results: We report the isolation, genomic and functional characterization of a novel bacteriophage lytic for Klebsiella oxytoca, which does not infect the closely related Klebsiella pneumoniae. This bacteriophage was formulated into suppositories and troches and shown to be released and lyse underlying Klebsiella oxytoca bacteria in an in-vitro model.

Encapsulation of Mitoxantrone within Cucurbit[8]uril Decreases Toxicity and Enhances Survival in a Mouse Model of Cancer.

Mitoxantrone was efficiently encapsulated within cucurbit[8]uril in a 2:1 complex where the two mitoxantrone molecules were symmetrically located through both portals of a cucurbit[8]uril cage. The novel complex facilitates increased mitoxantrone uptake in mouse breast cancer cells and decreases the toxicity of the drug in healthy mice. In an orthotopic mouse model of metastatic breast cancer the complex still maintains anticancer activity compared to the free drug, yet provides a statistically significant increase in the survival of these mice compared to conventional mitoxantrone treatment.

Dynamic interactions between prophages induce lysis in Propionibacterium acnes.

Progress in next-generation sequencing technologies has facilitated investigations into microbial dynamics. An important bacterium in the dairy industry is Propionibacterium freudenreichii, which is exploited to manufacture Swiss cheeses. A healthy culture of these bacteria ensures a consistent cheese with formed 'eyes' and pleasant flavour profile, and the investigation of prophages and their interactions with these bacteria could assist in the maintenance of the standard of this food product.

Rab1-dependent ER-Golgi transport dysfunction is a common pathogenic mechanism in SOD1, TDP-43 and FUS-associated ALS.

Several diverse proteins are linked genetically/pathologically to neurodegeneration in amyotrophic lateral sclerosis (ALS) including SOD1, TDP-43 and FUS. Using a variety of cellular and biochemical techniques, we demonstrate that ALS-associated mutant TDP-43, FUS and SOD1 inhibit protein transport between the endoplasmic reticulum (ER) and Golgi apparatus in neuronal cells. ER-Golgi transport was also inhibited in embryonic cortical and motor neurons obtained from a widely used animal model (SOD1(G93A) mice), validating this mechanism as an early event in disease.

Loss of Host Type-I IFN Signaling Accelerates Metastasis and Impairs NK-cell Antitumor Function in Multiple Models of Breast Cancer.

Metastatic progression is the major cause of breast cancer-related mortality. By examining multiple syngeneic preclinical breast cancer models in mice lacking a functional type-I interferon receptor (Ifnar1(-/-) mice), we show that host-derived type-I interferon (IFN) signaling is a critical determinant of metastatic spread that is independent of primary tumor growth. In particular, we show that bone metastasis can be accelerated in Balb/c Ifnar1(-/-) mice bearing either 4T1 or 66cl4 orthotopic tumors and, for the first time, present data showing the development of bone metastasis in the C57Bl/6 spontaneous MMTV-PyMT-driven model of tumorigenesis.

Genetic disruption of the sh3pxd2a gene reveals an essential role in mouse development and the existence of a novel isoform of tks5.

Tks5 is a scaffold protein and Src substrate involved in cell migration and matrix degradation through its essential role in invadosome formation and function. We have previously described that Tks5 is fundamental for zebrafish neural crest cell migration in vivo. In the present study, we sought to investigate the function of Tks5 in mammalian development by analyzing mice mutant for sh3pxd2a, the gene encoding Tks5.
