Mycobacterium tuberculosis (Mtb)-induced autophagy of alveolar macrophages has been confirmed to play a central role in the pathogenesis of tuberculosis. Growing evidence indicates that excessive or uncontrolled autophagic activity, which results in type II programmed cell death, can be regulated by many factors, including Wnt/β-catenin signalling. Wnt/β-catenin signalling has been demonstrated to be involved in multiple diseases through the regulation of autophagy; however, its exact role in regulating autophagy induced by Mtb remains unclear...

We explored the pollen foraging behavior of honey bee colonies situated in the corn and soybean dominated agroecosystems of central Ohio over a month-long period using both pollen metabarcoding and waggle dance inference of spatial foraging patterns. For molecular pollen analysis we developed simple and cost-effective laboratory and bioinformatics methods. Targeting four plant barcode loci (ITS2, rbcL, trnL and trnH), we implemented metabarcoding library preparation and dual-indexing protocols designed to minimize amplification biases and index mis-tagging events...

Innate immunity is the first line of defense against invading pathogens and plays an essential role in defending the brain against infection, injury, and disease. It is currently well recognized that central nervous system (CNS) infections can result in long-lasting neurological sequelae and that innate immune and inflammatory reactions are highly implicated in the pathogenesis of neurodegeneration. Due to the conservation of the mechanisms that govern neural development and innate immune activation from flies to mammals, the lack of a classical adaptive immune system and the availability of numerous genetic and genomic tools, the fruit fly Drosophila melanogaster presents opportunities to investigate the cellular and molecular mechanisms associated with immune function in brain tissue and how they relate to infection, injury and neurodegenerative diseases...

BACKGROUND: Paraneoplastic neurological syndromes (PNS) are a group of syndromes that affect the central and peripheral neuromuscular system in association with cancer. Specific antibodies may assist in the diagnosis of PNS. The antibodies tested can be classified into those directed against intracellular neuronal proteins ("well characterized" PNS: Hu, Yo, RI, CV2, amphiphysin, Ma1, Ma2) and those directed against neural surface antigens (autoimmune encephalitis syndromes: NMDA, AMPA, LGI1, CASPR2, GABAR)...

An 86-year-old female with previously diagnosed congenitally absent right internal carotid artery presented for total shoulder arthroplasty. Bedside ultrasonography confirmed the anomaly and identified several arterial collateral vessels. No aberrant vessels were seen traversing the brachial plexus. The patient received brachial plexus blockade and general anesthesia for the procedure. Carotid agenesis is associated with increased prevalence of intracranial aneurysm. Patients are often asymptomatic due to adequate blood supply from collateral vessels...

Circulating antineutrophil cytoplasmic antibodies (ANCAs) are the central pathogenic mechanism for a group of systemic and renal syndromes called the ANCA-associated vasculitis (AAV). The nomenclature has changed from eponymous labeling to granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, and microscopic polyangiitis. These syndromes predominantly affect the pulmonary and renal systems. We also review the molecular pathology behind ANCAs and associated antigens and infections...

BACKGROUND: Glioma is the most prevalent malignant tumor in human central nervous systems. Recently, the development of resistance to radiotherapy in glioma patients markedly vitiates the therapy outcome. MiR-153-3p has been reported to be closely correlated with tumor progression, but its effect and molecular mechanism underlying radioresistance remains unclear in glioma. METHODS: The expression of miR-153-3p was determined in radioresistant glioma clinical specimens as well as glioma cell lines exposed to irradiation (IR) using quantitative real-time PCR...

Recurrent primary central nervous system lymphomas (PCNSL) have a very poor prognosis. For young and fit patients, intensive chemotherapy followed by autologous stem cell transplantation could be proposed at relapse. In the other cases (unfit or elderly patients), therapeutic options are limited with no consensual regimen. The poly-chemotherapy by (R)-GEMOX is associated with anti-tumor activity in systemic lymphomas and a favorable toxicity profile. Our objective was to evaluate the activity and tolerance of (R)-GEMOX in PCNSL patients enrolled in the French nation-wide LOC cohort...

Myelin loss subsequent to oligodendrocyte death has been reported in a variety of myelin-associated disorders such as multiple sclerosis (MS). Lipopolysaccharide (LPS) has been shown to elicit cellular responses in the central nervous system (CNS) and trigger immune infiltrates and glial cells to release a variety of inflammatory cytokines and mediators. LPS-induced oligodendrocytes toxicity may be chosen as an efficient model to evaluate the role of oligodendrocytes in neuroprotective activities of compounds...

This study assessed the compliance of Belgian home care nurses with good practice recommendations to prevent central line-associated bloodstream infections. The compliance to 3 care bundles was 0% (0 out of 7), 13.3% (2 out of 15), and 22.2% (2 out of 9), respectively. This finding is important given the increasing number of home care patients with an intravascular catheter and underscores the need for quality improvement strategies to prevent central line-associated bloodstream infections in home care.

BACKGROUND: Sustaining healthcare-associated infection (HAI) prevention practices is complex. We examined the use of Kamishibai Cards (K Cards) as a tool to encourage compliance interactions between leaders and staff. METHODS: We explored one unit of a children's hospital to assess acceptability of K Cards. Interactions were recorded (n = 14), and interviews were conducted (n = 22). We used the Health Belief Model (HBM) for analyses. Central line utilization, bundle compliance and rates of HAIs were also examined...

BACKGROUND: Central venous oxygen saturation (ScvO2) is correlated with cardiac output. In most patients, ScvO2 declines during hemodialysis (HD) due to factors such as reduced preload, myocardial stunning, and intermittent arrhythmias. Previous research has shown that low ScvO2 is associated with higher mortality in chronic HD patients. In this research, we tested the hypothesis that ScvO2 variability is associated with all-cause mortality. METHODS: We conducted a retrospective study in 232 chronic HD patients with central venous catheter as vascular access...

Radiotherapy plays a vital role in cancer treatment, for which accurate prognosis is important for guiding sequential treatment and improving the curative effect for patients. An issue of great significance in radiotherapy is to assess tumor radiosensitivity for devising the optimal treatment strategy. Previous studies focused on gene expression in cells closely associated with radiosensitivity, but factors such as the response of a cancer patient to irradiation and the patient survival time are largely ignored...

In the current study, we performed a complete analysis, with four different methods, of all four HER family receptors, in a series of patients with metastatic breast cancer treated with trastuzumab-based regimens and evaluated their prognostic value. Formalin-fixed paraffin-embedded tumor tissue samples were collected from 227 patients, considered to be HER2-positive when assessed at the local laboratories. We evaluated gene amplification, copy number variations (CNVs), mRNA and protein expression of all four HER family members...

OBJECTIVE: Current practice guidelines recommend cefazolin, cefoxitin, cefotetan, or ampicillin-sulbactam as first-line antibiotic prophylaxis in hysterectomy. We undertook this systematic review and meta-analysis of randomized controlled trials (RCTs) to determine whether cefazolin, with limited antianaerobic spectrum, is as effective in preventing surgical site-infection (SSI) as the other first-choice antimicrobials that have more extensive antianaerobic activity. METHODS: We searched PubMed, Scopus, Web of Science, Cochrane Central, and EMBASE for relevant randomized controlled trials (RCT) in any language up to January 23, 2018...

BACKGROUND: Glioblastoma multiforme (GBM) is the most malignant central nervous system tumor. Alkylating agent, temozolomide (TMZ), is currently the first-line chemotherapeutic agent for GBM. However, the sensitivity of GBM cells to TMZ is affected by many factors. And, several clinic trials, including co-administration of TMZ with other drugs, have failed in successful treatment of GBM. We have previously reported that Netrin-4 (NTN4), a laminin-like axon guidance protein, plays a protective role in GBM cell senescence upon TMZ-triggered DNA damage...
