BACKGROUND: The aim of this postmortem study was to compare, in Parkinson's disease subjects with and without bilateral subthalamic nucleus deep brain stimulation (STN-DBS), the loss of pigmented neurons within the substantia nigra and pathological alpha-synuclein density within the SN and other brain regions. METHODS: PD subjects were identified from the Arizona Study of Aging and Neurodegenerative Disorders database (STN-DBS = 11, non-DBS = 156). Pigmented neuron loss scores within the substantia nigra as well as alpha-synuclein density scores within the substantia nigra and 9 other brain regions were compared, the latter individually and in summary as the Lewy body brain load score...

AIM: In this observational study using 3T magnetic resonance imaging (MRI) and diffusion tensor, we investigated the differential effects of pathology, stage of disease, state of consciousness, and aetiology on the modifications of supra- and infra-tentorial white matter tracts and their correlations with clinical scales in paediatric patients with severe non-traumatic brain injury. METHOD: Diffusion tensor magnetic resonance imaging (DT-MRI) was obtained from seven children with unresponsive wakefulness syndrome (UWS; five males, two females; age at event 5y; standard deviation [SD] 2y 1mo), six children in a minimally conscious state (MCS; three males, three females; age at event 5y 10mo; SD 5y), and 10 healthy children as controls(two males, eight females; age at study 10y 10mo; SD 2y 10mo)...

Solithromycin is a novel fluoroketolide developed in both oral and intravenous formulations to address increasing macrolide resistance in pathogens causing community-acquired bacterial pneumonia (CABP). When compared with its macrolide and ketolide predecessors, solithromycin has several structural modifications which increase its ribosomal binding and reduce its propensity to known macrolide resistance mechanisms. Solithromycin, like telithromycin, affects 50S ribosomal subunit formation and function, as well as causing frame-shift errors during translation...

The HIV accessory protein Nef is a major determinant of viral pathogenesis that facilitates viral particle release, prevents viral antigen presentation and increases infectivity of new virus particles. These functions of Nef involve its ability to remove specific host proteins from the surface of infected cells, including the CD4 receptor. Nef binds to the adaptor protein 2 (AP-2) and CD4 in clathrin-coated pits, forcing CD4 internalization and subsequent target to lysosomes. Herein, we report that this lysosomal targeting requires a variant of the AP-1 comprising the isoform 2 of γ-adaptin...

BACKGROUND: The mechanisms involved in the amplification of the mast cell response during anaphylaxis are unclear. Mouse models of anaphylaxis demonstrate the critical involvement of neutrophils. These innate immune cells are highly abundant in peripheral blood and can be rapidly activated to trigger both local and systemic inflammation. OBJECTIVE: To investigate neutrophil activation in peripheral blood during acute human anaphylaxis. METHODS: Patients presenting to the Emergency Department with anaphylaxis underwent blood sampling upon enrolment and at up to three subsequent time points...

Therapeutic approaches to block the progression from acute kidney injury to chronic kidney disease are currently lacking. Endothelin-1 (ET-1) is a powerful vasoconstrictor, induced by hypoxia, and previously implicated in renal ischemia-reperfusion (IR) injury. This study tested the hypothesis that blunting the vascular influence of ET-1, either through endothelin ETA receptor blockade (ABT-627) or vascular endothelial cell deletion of ET-1 (VEET KO), would improve recovery of renal perfusion and repair of injury following a severe ischemic insult in mice (45 min unilateral renal ischemia)...

Vincristine is a chemotherapeutic agent that is a component of many combination regimens for a variety of malignancies, including several common pediatric tumors. Vincristine treatment is limited by a progressive sensorimotor peripheral neuropathy. Vincristine-induced peripheral neuropathy (VIPN) is particularly challenging to detect and monitor in pediatric patients, in whom the side effect can diminish long term quality of life. This review summarizes the current state of knowledge regarding VIPN, focusing on its description, assessment, prediction, prevention, and treatment...

Tissue-resident memory T (TRM) cells, a population of noncirculating memory T cells, are one of the essential components of immunological memory in both mouse and human. Although CD69(+)CD103(+) TRM cells represent a major TRM cell population in barrier tissues including the mucosal surface and the skin, CD69(+)CD103(-) TRM cells dominate most nonbarrier tissues, such as the kidney. TGF-β is required for the differentiation of CD69(+)CD103(+) TRM cells in barrier tissues. However, the developmental control of CD69(+)CD103(-) TRM cells in nonbarrier tissues remains largely unknown and the involvement of TGF-β signaling is less clear...

The presence of multiple primary tumors (MPT) in a single patient has been identified with an increasing frequency. A critical issue is to establish if the second tumor represents an independent primary cancer or a metastasis. Therefore, the assessment of MPT clonal origin might help understand the disease behavior and improve the management/prognosis of the patient.Herein, we report a 73-year-old male smoker who developed 2 primary lung cancers (adenocarcinoma and squamous cell carcinoma) and a malignant peritoneal mesothelioma (PM)...

The superficial dorsal horn, which is the main target for nociceptive and pruritoceptive primary afferents, contains a high density of excitatory interneurons. Our understanding of their roles in somatosensory processing has been restricted by the difficulty of distinguishing functional populations among these cells. We recently defined three non-overlapping populations among the excitatory neurons, based on the expression of neurotensin, neurokinin B (NKB) and gastrin-releasing peptide (GRP). Here we identify and characterise another population: neurons that express the tachykinin peptide substance P...

Emerging antibiotic resistance in the oropharyngeal microbiota, of which Streptococcus salivarius is a prominent species, represents a challenge for treating pediatric populations. In this study, we investigated the role of S. salivarius as a reservoir for antibiotic resistance genes (ARG) in the oral microbiota by analyzing 95 S. salivarius isolates from 22 healthy infants (2 to 16 months of age). Minimum inhibitory concentrations (MIC) of penicillin G, amoxicillin, erythromycin, tetracycline, doxycycline and streptomycin were determined...

Because of the intensive use of pharmaceutical substances in human life, studies on the detection of these chemical compounds and their metabolites as pollutants in water bodies are continuously reported. Some pharmaceutical agents are associated with adverse effects to aquatic life, even at very low concentrations (ng L(-1) to μg L(-1)). For instance, the presence of antibiotics and hormones has been associated with increasing proliferation of antibiotic resistant pathogens and feminization and masculinization of some aquatic organisms...

Maternal milk is the optimal food for newborns. To this end, a number of interventions are used to enhance milk production. However, pharmacological interventions may be associated with a perceived risk of adverse effects and therefore many mothers prefer to rely on natural herbal remedies. Several herbal remedies have been traditionally used to this purpose. However, the level of evidence supporting their use is mixed. Among different currently-employed natural remedies, Galega officinalis has emerged to be one of those sustained by the strongest evidence...
