https://www.readbyqxmd.com/read/28527263/-racemose-neurocysticercosis-neuroimaging-guides-the-diagnosis
#1
Carlos Hugo Zapata, Sergio Alberto Vargas, Carlos Santiago Uribe
Neurocysticercosis is the leading cause of parasitosis of the central nervous system and acquired epilepsy in developing countries. The clinical manifestations of neurocysticercosis, especially its racemose variant, are pleomorphic and unspecific, characteristics that hinder the diagnosis and make it a challenge for the clinician.The objective of this report was to describe two cases of racemose neurocysticercosis in which neuroimaging led to the definitive diagnosis. The first case involved a patient with persistent headache and focal neurological signs...

In this study, we investigated the effects of age and of mild cognitive impairment (MCI) on decision making under risk by adopting a task representing real-life health-related situations and involving complex numerical information. Moreover, we assessed the relationship of real-life decision making to other cognitive functions such as number processing, executive functions, language, memory, and attention. For this reason, we compared the performance of 19 healthy, relatively younger adults with that of 18 healthy older adults as well as the performance of the 18 healthy older adults with that of 17 patients with MCI...

Mycobacterium chelonae is a nontuberculous mycobacterium, classified as a Runyon type IV mycobacterium. In relation to humans, it is most commonly associated with tissue trauma or pulmonary infections. The majority of medical reports describe finding M. chelonae in the surgical setting, attributing infection to inadequate sterilization of surgical equipment. Symptoms are often nonspecific and include pain, erythema, and draining subcutaneous nodules and skin lesions. Therefore, the diagnosis of M. chelonae is often difficult to establish without prior suspicion of the disease, but can be confirmed with culture...

BACKGROUND: A split-thickness skin graft (STSG) is performed to cover a large full-thickness skin defect. Esthetic and functional deficits can result, and many studies have sought to overcome them. This study compared the effectiveness of the acellular dermal matrix (ADM) graft and STSG concerning esthetic and functional effectiveness of ADM on scar quality. METHODS: Of the patients who underwent anterolateral thigh free flap from 2011 to 2015, patients who received skin graft only (n = 10) or skin graft with ADM (n = 20) for coverage of the donor site were enrolled...

R-type tailocins are high molecular weight bacteriocins that resemble bacteriophage tails and are encoded within the genomes of many Pseudomonas species. In this study, analysis of the P. chlororaphis 30-84 R-tailocin gene cluster revealed that it encodes the structural components to produce two R-tailocins of different ancestral origin. Two distinct R-tailocin populations differing in length were observed in UV induced lysates of P. chlororaphis 30-84 via transmission electron microscopy. Mutants defective in the production of one or both R-tailocins demonstrated that the killing spectrum of each tailocin is limited to Pseudomonas species...

Nitramines are key constituents of most of the explosives in current use and consequently contaminate soil and groundwater at many military facilities around the world. Toxicity from nitramine contamination poses a health risk to plants and animals, thus understanding how nitramines are biodegraded is critical to environmental remediation. The biodegradation of synthetic nitramine compounds such as hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) has been studied for decades, but little is known about the catabolism of naturally produced nitramine compounds...

Sleep is an evolutionarily conserved process required for human health and functioning. Insufficient sleep causes impairments across cognitive domains, and sleep deprivation can have rapid antidepressive effects in mood disorders. However, the neurobiological effects of waking and sleep are not well understood. Recently, animal studies indicated that waking and sleep are associated with substantial cortical structural plasticity. Here, we hypothesized that structural plasticity can be observed after a day of waking and sleep deprivation in the human cerebral cortex...

Several lines of evidence indicate that adverse experience in early life may be a triggering factor for disturbances in the brain mitochondrial proteins and lead to the development of depression in adulthood. On the other hand, little is known about the impact of chronic administration of various antidepressant drugs on the brain mitochondria, as a target for the pharmacotherapy of depression. The purpose of our study was to compare the impact of chronic treatment with two antidepressant drugs with different mechanisms of action, a tricyclic antidepressant (TCA), imipramine, and an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class, fluoxetine, on the mitochondria-enriched subproteome profile in the hippocampus of 3-month-old male rats following a prenatal stress procedure (an animal model of depression)...

BACKGROUND: The CXCR4-CXCL12 axis plays an important role in the chronic lymphocytic leukemia (CLL)-microenvironment interaction. Overexpression of CXCR4 has been reported in different hematological malignancies including CLL. Binding of the pro-survival chemokine CXCL12 with its cognate receptor CXCR4 induces cell migration. CXCL12/CXCR4 signaling axis promotes cell survival and proliferation and may contribute to the tropism of leukemia cells towards lymphoid tissues and bone marrow...

BACKGROUND: Hyperexcitability of neuronal networks can lead to excessive release of the excitatory neurotransmitter glutamate, which in turn can cause neuronal damage by overactivating NMDA-type glutamate receptors and related signaling pathways. This process (excitotoxicity) has been implicated in the pathogenesis of many neurological conditions, ranging from childhood epilepsies to stroke and neurodegenerative disorders such as Alzheimer's disease (AD). Reducing neuronal levels of the microtubule-associated protein tau counteracts network hyperexcitability of diverse causes, but whether this strategy can also diminish downstream excitotoxicity is less clear...

Evidence shows that there are individual differences in the extent to which people attend to and integrate information into their decisions about the predictive contingencies between events and outcomes. In particular, information about the absence of events or outcomes, presented outside the current task frame, is often neglected. This trend is particularly evident in depression, as well as other psychopathologies, though reasons for information neglect remain unclear. We investigated this phenomenon across two experiments (Experiment 1: N=157; Experiment 2: N=150) in which participants, scoring low and high in the Beck Depression Inventory, were asked to learn a simple predictive relationship between a visual cue and an auditory outcome...

Background and Aims: Preliminary evidence suggests fermentable carbohydrate restriction might ameliorate functional gastrointestinal symptoms (FGS) in quiescent inflammatory bowel disease (IBD). Our aim was to determine whether fermentable carbohydrates exacerbate FGS in quiescent IBD using a randomised, double-blinded, placebo-controlled, cross-over, re-challenge trial. Methods: Patients with quiescent IBD and FGS responsive to a low FODMAP diet were allocated to a series of 3-day fermentable carbohydrate challenges in random order (fructan, 12 g/d; galacto-oligosaccharides, GOS, 6 g/d; sorbitol, 6 g/d; and glucose placebo, 12 g/d), each separated by a standardised washout period...

Fungicides should be used to the extent required to minimize economic costs of disease in a given field in a given season. The maximum number of treatments and maximum dose per treatment are set by fungicide manufacturers and regulators at a level that provides effective control under high disease pressure. Lower doses are economically optimal under low or moderate disease pressure, or where other control measures such as resistant cultivars constrain epidemics. Farmers in many countries often apply reduced doses, although they may still apply higher doses than the optimum to insure against losses in high disease seasons...

Ryuji Kato, Jack Uetrecht
There is increasing evidence that most idiosyncratic drug-induced liver injury (IDILI) is immune mediated, and in most cases reactive metabolites appear to be responsible for induction of this immune response. Reactive metabolites can cause cell damage with the release of damage-associated molecular patterns (DAMPs), which is thought to be involved in immune activation. Presumably the reason that the liver is a common target of idiosyncratic drug reactions is because it is the major site of drug metabolism and reactive metabolite formation...

To identify the house mice collected in Pokhara and Lumbini of Nepal at the subspecies level, morphological and molecular analyses were carried out. Morphologically, two populations collected in Pokhara and Lumbini were distinguished by fur colour, but there was no significant difference in external measurements (p > .05). The phylogenetic analysis results revealed that the haplotypes sequences of mitochondrial DNA (mtDNA) Cytochrome B (CytB) gene distinguished into two distinct clades on a phylogenetic tree representing two subspecies, Mus musculus bactrianus and M...

Should we continue to refer to autism as a 'disease' or 'disorder', or is the framework of 'neurodiversity' a more humane and accurate lens through which to view people with autism? Evidence at the genetic, neural, behavioural and cognitive levels reveals people with autism show both differences, and signs of disability, but not disorder. Disability requires societal support, acceptance of difference and diversity, and societal "reasonable adjustment", whilst disorder is usually taken to require cure or treatment...

BACKGROUND/AIM: Determination of fitness-to-drive after illness or injury is a complex process typically requiring a comprehensive driving assessment, including off-road and on-road assessment components. The competency standards for occupational therapy driver assessors (Victoria, Australia) define the requirements for performance of a comprehensive driving assessment, and we are currently revising these. Assessment of cognitive and perceptual skills forms an important part of the off-road assessment...
