A Classic Neurocysticercosis Case with an Unusual Complication.

Unlabelled: Cysticercosis is triggered by infection with the larval form of the tapeworm . The usual sites for the development of cyscticerci are the central nervous system (neurocysticercosis - NCC), subcutaneous tissue, skeletal muscle, heart muscle, and the eye. Ocular cysticercosis is caused by the growth of the larvae within ocular tissues.

Forensic botany and forensic chemistry working together: application of plant DNA barcoding as a complement to forensic chemistry-a case study in Brazil.

Recently, Brazilian Federal Police used forensic chemistry and forensic botany techniques on a case. Two packets containing fragmented plant matter were seized and sent for forensic analysis. Forensic chemistry, the gold standard for evaluating plant material suspected to contain illicit substances, did not find illicit materials.

Recurrent water deficit causes alterations in the profile of redox proteins in citrus plants.

Plant acclimation to recurrent stress involves profound alterations in multiple genetic, metabolic and physiological processes. Stressful conditions usually implicate imbalance in reactive oxygen species (ROS) production and removal rates, which may lead to oxidative stress. However, the primary cellular targets of oxidative stress and their relevance in plant acclimation to abiotic stresses remains poorly characterized.

An Unusual Case of CMV/EBV Ventriculoencephalitis with Evolution to Primary Central Nervous System Lymphoma in HIV-Positive Patient.

Epstein-Barr virus (EBV) is a well-known cause of different types of malignancies particularly Burkitt's lymphoma, nasopharyngeal carcinoma, Hodgkin's lymphomas, and non-Hodgkin's lymphomas including primary central nervous system lymphoma (PCNSL). A higher tendency of malignant transformation associated with EBV has been noticed in immunocompromised patients, such as human immunodeficiency virus (HIV) infected patients. The rapid and effective immune reconstitution is crucial to prevent PCNSL in HIV-positive patients.

[Burden of healthcare-associated infections in outpatient care].

There is little evidence on healthcare-associated infections in outpatient care. The Swiss Federal Office for Public Health commissioned a systematic review to estimate the incidence of healthcare-associated infections in non-institutional settings. A total of 126 papers were eligible for data abstraction.

Individual and interpersonal emotion regulation among adults with substance use disorders and matched controls.

Objectives: Self-report studies show that negative emotional states and ineffective use of emotion regulation strategies are key maintaining factors of substance use disorders (SUD). However, experimental research into emotional processing in adults with SUD is in its infancy. Theoretical conceptualizations of emotion regulation have shifted from a focus on individual (internal) processes to one that encompasses social and interpersonal functions - including the regulation of facial expression of emotion.

Recurrent water deficit causes epigenetic and hormonal changes in citrus plants.

The present study evaluated the physiological, molecular and hormonal parameters from scion/rootstock interaction of citrus plants during recurrent water deficit. Responses of the Valencia (VO) scion variety grafted on two rootstocks with different soil water extraction capacities, Rangpur Lime (RL) and Sunki Maravilha (SM), during three successive periods of water deficit: plants exposed to a single episode of water deficit (WD1) and plants exposed to two (WD2) and three (WD3) recurrent periods of WD were compared. The combinations VO/RL and VO/SM presented polymorphic alterations of epigenetic marks and hormonal (i.

GC-MS quantitative analysis of black market pharmaceutical products containing anabolic androgenic steroids seized by the Brazilian Federal Police.

The use of counterfeit or substandard medicines can have an important health impact, resulting in therapeutic failure, be toxic or even cause death. Anabolic steroids are a frequent target for counterfeiters worldwide, being the second most frequent counterfeited class in Brazil. The aims of this work were to optimize and validate a GC-MS method for the quantitative determination of anabolic steroids in tablet, aqueous suspension and oil solution forms, and to analyze pharmaceutical products sent to Brazilian Federal Police (BFP) for forensic analysis.

Determination of caffeine and identification of undeclared substances in dietary supplements and caffeine dietary exposure assessment.

Caffeine is one of the most consumed stimulants in the world, and is a frequent ingredient of dietary supplements. The aims of this work were to validate a GC-MS method for the quantitation of caffeine and identification of other substances in supplements, mainly weight loss products, and to estimate the caffeine intake by consumers. Sample preparation included extraction with chloroform:water in ultrasonic bath, centrifugation and analysis of the organic layer for caffeine quantitation, and extraction with methanol for identification of other substances.

Expression of the citrus CsTIP2;1 gene improves tobacco plant growth, antioxidant capacity and physiological adaptation under stress conditions.

Overexpression of the citrus CsTIP2;1 improves plant growth and tolerance to salt and drought stresses by enhancing cell expansion, H O detoxification and stomatal conductance. Tonoplast intrinsic proteins (TIPs) are a subfamily of aquaporins, belonging to the major intrinsic protein family. In a previous study, we have shown that a citrus TIP isoform, CsTIP2;1, is highly expressed in leaves and also transcriptionally regulated in leaves and roots by salt and drought stresses and infection by 'Candidatus Liberibacter asiaticus', the causal agent of the Huanglongbing disease, suggesting its involvement in the regulation of the flow of water and nutrients required during both normal growth and stress conditions.

Survival strategies of citrus rootstocks subjected to drought.

Two citrus rootstocks, Rangpur lime (RL) and Sunki Maravilha mandarin (SM), were analyzed either ungrafted or grafted with their reciprocal graft combinations or with shoot scions of two commercial citrus varieties: Valencia orange (VO) and Tahiti acid lime (TAL). All graft combinations were subjected to distinct watering regimes: well-watered, severe drought and rehydration. Growth and water relation parameters, gas exchange as well as sugar and hormone profiles were determined.

Comparative study of the protein profiles of Sunki mandarin and Rangpur lime plants in response to water deficit.

Background: Rootstocks play a major role in the tolerance of citrus plants to water deficit by controlling and adjusting the water supply to meet the transpiration demand of the shoots. Alterations in protein abundance in citrus roots are crucial for plant adaptation to water deficit. We performed two-dimensional electrophoresis (2-DE) separation followed by LC/MS/MS to assess the proteome responses of the roots of two citrus rootstocks, Rangpur lime (Citrus limonia Osbeck) and 'Sunki Maravilha' (Citrus sunki) mandarin, which show contrasting tolerances to water deficits at the physiological and molecular levels.

Bacillary angiomatosis in a HIV-positive patient with poor adherence to antiretroviral therapy.

Bacillary angiomatosis is a systemic disease caused by Bartonella (B.) henselae and B. quintana.

The profile and practice of nuclear medicine technologists in Portugal: findings from a nationwide survey.

Objectives: Nuclear medicine (NM) is a rapidly developing field. In Portugal, no occupational study has been conducted yet that characterizes the professional profile of NM technologists (NMTs). We investigated the clinical tasks performed by NMTs in Portugal, analysing their practices with regard to radiation protection matters and their compliance with established international guidelines for best practice.

Antimony in plasma and skin of patients with cutaneous leishmaniasis--relationship with side effects after treatment with meglumine antimoniate.

Objective: To evaluate the levels of antimony in plasma and skin of patients being treated with pentavalent antimonials (Glucantime) and their relationship with side effects.

Methods: We evaluated 19 patients treated endovenously at the conventional dose (20 mg Sb(v)/kg/day), two at a smaller dose (5 mg Sb(v)/kg/day) and three treated intralesionally (up to 4.0 ml/week).
