NF1-dependent disruption of the blood-nerve-barrier is improved by blockade of P2RY14.

The blood-nerve-barrier (BNB) that regulates peripheral nerve homeostasis is formed by endoneurial capillaries and perineurial cells surrounding the Schwann cell (SC)-rich endoneurium. Barrier dysfunction is common in human tumorigenesis, including in some nerve tumors. We identify barrier disruption in human deficient neurofibromas, which were characterized by reduced perineurial cell glucose transporter 1 (GLUT1) expression and increased endoneurial fibrin(ogen) deposition.

Evaluation of LN34 Pan-Lyssavirus RT-qPCR assay for rabies diagnosis in Brazil.

Rabies, a fatal zoonotic viral disease affecting mammals, including humans, remains a significant global health concern, particularly in low-income countries. The disease, primarily transmitted through infected animal saliva, prompts urgent diagnosis for timely post-exposure prophylaxis (PEP). The gold standard diagnostic test, direct fluorescent antibody test (dFAT), while sensitive, suffers from limitations such as subjective interpretation and high costs.

Rabies Virus-Neutralizing Antibodies in Free-Ranging Invasive Wild Boars () from Brazil.

Rabies, one of the most lethal global zoonoses, affects all mammals. It remains circulating worldwide in sylvatic cycles through terrestrial and airborne reservoirs, and in Brazil, bats are currently the main reservoirs and source of transmission. Wild boars, an important invasive alien species in Brazil, are a proven food source for hematophagous bats and may participate in the Brazilian sylvatic cycle of rabies.

Evaluation of the effect of sample suspension concentration and viral load on the outcome of the rabies tissue culture infection test.

In this study, we examined various brain suspension concentrations and viral loads in Neuro-2a cell cultures using 20 rabies-positive bovine samples. The reproducibility of results varied: 65% showed consistent outcomes across all concentrations, while 35% disagreed in at least one. Viral titers ranged from less than 25 × 10 to 25 × 10 TCID/mL, with 20% below 25 × 10 TCID/mL.

Effect of experimental modulation of mood on exertional dyspnoea in chronic obstructive pulmonary disease.

Background And Objective: Dyspnoea is a debilitating symptom in individuals with chronic obstructive pulmonary disease (COPD) and a range of other chronic cardiopulmonary diseases and is often associated with anxiety and depression. The present study examined the effect of visually-induced mood shifts on exertional dyspnoea in individuals with COPD.

Methods: Following familiarization, 20 participants with mild to severe COPD (age 57-79 years) attended three experimental sessions on separate days, performing two 5-min treadmill exercise tests separated by a 30-min interval on each day.

On some mummy findings from the Semmelweis Museum of Medical History, Hungarian National Museum, Budapest.

The permanent exhibition of the Hungarian National Museum, Semmelweis Museum of Medical History of Budapest, Hungary, displays some human remains believed to originate from ancient Egypt. Within the framework of the Nephthys Project, three objects consisting of two heads and one foot were studied via paleoimaging and archaeometric techniques in order to provide new anthropological and paleopathological data. It is argued here that even partial or fragmentary items are worthy of investigation as they can reveal new information about their owners, as well as their supposed authenticity.

Seroprevalence to Rabies Virus in Wildlife in Brazil.

Serum samples of 638 free-ranging wild mammals from São Paulo state, Brazil, were tested for neutralizing antibodies against rabies virus by the rapid fluorescent focus inhibition test. Overall seroprevalence was 1.7% among 24 species surveyed, with individuals of six species having positive results indicating exposure to rabies virus.

Ventilator versus manual hyperinflation in adults receiving mechanical ventilation: A systematic review.

Introduction: Manual hyperinflation (MHI) or with a mechanical ventilator (VHI) are alternatives in bronchial hygiene therapy, in recent years several studies have emerged with the objective of verifying the effectiveness and safety of the techniques.

Objective: Systematically review and analyze the most recent studies in the literature on MHI and VHI, compare both techniques and demonstrate their effectiveness in bronchial hygiene therapy in mechanically ventilated patients.

Methods: We conducted this systematic review based on the PICO strategy and used the databases Ovid, LILACS, CINAHL, Pubmed and CENTRAL.

Serological Surveillance of Rabies in Free-Range and Captive Common Vampire Bats .

The control of vampire bat rabies (VBR) in Brazil is based on the culling of and the surveillance of outbreaks caused by in cattle and humans in addition to vaccination of susceptible livestock. The detection of anti-rabies antibodies in vampire bats indicates exposure to the rabies virus, and several studies have reported an increase of these antibodies following experimental infection. However, the dynamics of anti-rabies antibodies in natural populations of remains poorly understood.

Detection of rabies virus in cranial cavity lavage of naturally infected bats.

The rabies virus (RABV) has been isolated in several bats species in the world, and among them, hematophagous, frugivorous and insectivorous species. Bats found in Brazil are small, which can lead to situations in which there are limitations in the collection of the central nervous system (CNS) and the amount of material may be insufficient to carry out laboratory diagnostic techniques for rabies. The objective of this work was to evaluate an alternative sample collection for the diagnosis of rabies in bats.

[Uncomplicated urinary tract infections : Use of mustard oils].

Background: Increasing rates of multidrug resistant bacteria demand a change in managing infectious diseases. New ways of antibiotic-free treatment in uncomplicated urinary tract infections (UTI) saving antibiotics for severe infections should be chosen.

Objectives: Beside analgesics for purely symptomatic treatment, herbal medicine can be used for uncomplicated UTI instead of antibiotics.

Comparison of five different laboratory techniques for the rabies diagnosis in clinically suspected cattle in Brazil.

The direct-fluorescent antibody test (dFAT) is considered the "gold standard" assay to diagnose rabies. However, it is crucial to develop molecular techniques, such as RT-PCR and RT-qPCR, since many laboratories lack the needed supplies for performing complementary methods (viral isolation, for example). For this purpose, diagnostic techniques must be specific and sensitive to guarantee accuracy.

Tetraspanin CD9 affects HPV16 infection by modulating ADAM17 activity and the ERK signalling pathway.

Human papillomaviruses (HPV) are causative agents of various tumours such as cervical cancer. HPV binding to the cell surface of keratinocytes leads to virus endocytosis at tetraspanin enriched microdomains. Complex interactions of the capsid proteins with host proteins as well as ADAM17-dependent ERK1/2 signal transduction enable the entry platform assembly of the oncogenic HPV type 16.

Evaluation of polyclonal anti-RNP IgG antibody for rabies diagnosis by indirect rapid immunohistochemistry test.

Rabies still represents a major public health threat and estimated to cause 60,000 human deaths annually, particularly in developing countries. Thus, adequate surveillance based on rapid and reliable rabies diagnosis for both humans and animals is essential. The WHO and OIE recommended gold standard diagnostic technique for rabies is the direct immunofluorescence assay (dFAT).

Effects of Skin-to-Skin Care During Cesareans: A Quasiexperimental Feasibility/Pilot Study.

: Our aim was to describe feasibility and outcomes of skin-to-skin care (SSC) that began during cesarean surgery and continued, uninterrupted, for about 5 hours. We described maternal/newborn measures of physiologic stability and stress; maternal measures of comfort; maternal satisfaction with surgery and SSC; and exclusive breast milk feeding at discharge. We used a quasiexperimental, time-interrupted design and randomly assigned women to receive SSC that began during surgery (Group 1, intervention;  = 20) or after surgery, before transfer to recovery (Group 2, standard care;  = 20).

Large protein as a potential target for use in rabies diagnostics.

Rabies is a zoonotic viral disease that remains a serious threat to public health worldwide. The rabies lyssavirus (RABV) genome encodes five structural proteins, multifunctional and significant for pathogenicity. The large protein (L) presents well-conserved genomic regions, which may be a good alternative to generate informative datasets for development of new methods for rabies diagnosis.

A rabies virus vampire bat variant shows increased neuroinvasiveness in mice when compared to a carnivore variant.

Rabies is one of the most important zoonotic diseases and is caused by several rabies virus (RABV) variants. These variants can exhibit differences in neurovirulence, and few studies have attempted to evaluate the neuroinvasiveness of variants derived from vampire bats and wild carnivores. The aim of this study was to evaluate the neuropathogenesis of infection with two Brazilian RABV street variants (variant 3 and crab-eating fox) in mice.

The CD63-Syntenin-1 Complex Controls Post-Endocytic Trafficking of Oncogenic Human Papillomaviruses.

Human papillomaviruses enter host cells via a clathrin-independent endocytic pathway involving tetraspanin proteins. However, post-endocytic trafficking required for virus capsid disassembly remains unclear. Here we demonstrate that the early trafficking pathway of internalised HPV particles involves tetraspanin CD63, syntenin-1 and ESCRT-associated adaptor protein ALIX.

Group A rotavirus in Brazilian bats: description of novel T15 and H15 genotypes.

This study aimed to survey for group A rotaviruses (RVA) in bats from Brazil and to perform phylogenetic inferences for VP4, VP7, NSP3, NSP4 and NSP5 genes. RVA was found in 9.18 % (28/305) of tested samples.

Alphacoronavirus in urban Molossidae and Phyllostomidae bats, Brazil.

Background: Bats have been implicated as the main reservoir of coronavirus (CoV). Thus the role of these hosts on the evolution and spread of CoVs currently deserve the attention of emerging diseases surveillance programs. On the view of the interest on and importance of CoVs in bats the occurrence and molecular characterization of CoV were conducted in bats from Brazil.
