A 3-year-old, female Greater Swiss Mountain dog developed a hemoperitoneum following an exploratory laparotomy and ovariohysterectomy. Platelet count, PT, APTT, and plasma von Willebrand factor antigen concentration were within RIs. A buccal mucosal bleeding time (BMBT) was prolonged. Given the probability of a hereditary thrombopathia, the dog was administered desmopressin, fresh platelet transfusions, and aminocaproic acid to control hemorrhage. Subsequently, DNA testing for the P2Y12 receptor gene mutation identified the dog as being a heterozygote (carrier)...

In this work, Raman hyperspectral imaging, in conjunction with independent component analysis, was employed as an analytical methodology to detect an ammonium nitrate fuel oil (ANFO) explosive in banknotes after an ATM explosion experiment. The proposed methodology allows for the identification of the ANFO explosive without sample preparation or destroying the sample, at quantities as small as 70μgcm(-2). The explosive was identified following ICA data decomposition by the characteristic nitrate band at 1044cm(-1)...

The introduction of family-centered care in the neonatal intensive care unit was identified as a high priority to facilitate bonding and attachment with potential positive outcomes for the parents and infants. The aim of the study was, therefore, to develop and implement a quality improvement initiative to foster family-centered care in a tertiary neonatal intensive care unit from birth onward. A pretest posttest intervention design was used using mixed methods over 3 phases to determine the perceived level of family-centered care according to healthcare professionals and parents using self-administered questionnaires; to develop and implement a quality improvement initiative to enhance family-centered care in a neonatal intensive care unit using a nominal group technique, followed by the quality improvement process; and to evaluate the outcomes of the initiative by repeating the self-administered questionnaires to parents and staff...

The emergence of antibiotics and their active metabolites in aquatic ecosystem has motivated the development of sensitive and reliable sensors to monitor traces of antibiotics and metabolites in drinking water sources (i.e. surface water). The surface enhanced Raman scattering (SERS) technique, which is widely recognized as a high sensitivity method for molecular vibrational detection, is potentially a powerful tool for trace environmental contamination analysis. The main goal of this work is to demonstrate pharmaceutical and metabolite multiplexing detection using the SERS approach...

A previously unknown disease which causes severe vein thickening and inward leaf curl was observed in a number of opium poppy (Papaver somniferum L.) plants. The sequence analysis of full-length viral genome and associated betasatellite reveals the occurrence of Ageratum enation virus (AEV) and Ageratum leaf curl betasatellite (ALCB), respectively. Co-infiltration of cloned agroinfectious DNAs of AEV and ALCB induces the leaf curl and vein thickening symptoms as were observed naturally. Infectivity assay confirmed this complex as the cause of disease and also satisfied the Koch's postulates...

Alexandra Maas, Burkhard Madea, Cornelius Hess
Confirmation or exclusion of recent heroin consumption is still one of the major challenges for forensic and clinical toxicologists. A great variety of biomarkers is available for heroin abuse confirmation, including various opium alkaloids (e.g. morphine, codeine), street heroin impurities (e.g. 6-acetylcodeine (6-AC), noscapine, papaverine) as well as associated metabolites (e.g. 6-monoacetylmorphine (6-MAM), morphine glucuronides). Though, the presence of most of these biomarkers cannot solely be attributed to a previous heroin administration but can, among other things, also be due to consumption of poppy seed products ('poppy seed defense'), opium preparations or specific medications, respectively...

Biological oxidations form the basis of life on earth by utilizing organic compounds as electron donors to drive the generation of metabolic energy carriers, such as ATP. Oxidative reactions are also important for the biosynthesis of complex compounds, i.e. natural products such as alkaloids that provide vital benefits for organisms in all kingdoms of life. The vitamin B2-derived cofactors flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) enable an astonishingly diverse array of oxidative reactions that is based on the versatility of the redox-active isoalloxazine ring...

The short time of action and systemic toxicity of local anaesthetics limit their clinical application. Bupivacaine is the most frequently used local anaesthetic in surgical procedures worldwide. The discovery that its S(-) enantiomeric form is less toxic than the R(+) form led to the introduction of products with enantiomeric excess (S75:R25 bupivacaine) in the market. Nevertheless, the time of action of bupivacaine is still short; to overcome that, bupivacaine S75:R25 (BVCS75) was encapsulated in nanostructured lipid carriers (NLC)...

Evidence of human use of opium dates back as far as the sixth millennium BCE. Ancient societies through the Renaissance period created a variety of opium products, proliferating its common use and subsequent addiction. Because the active moiety was not known at this time, the potency of these opium concoctions could neither be predicted nor controlled. The first step in identifying opium's active ingredient, morphine, was its chemical isolation in the early 1800s by Wilhelm Sertürner. The subsequent elucidation of morphine's chemical formula and Sir Robert Robinson's derivation of morphine's structural formula, which won him the 1947 Nobel Prize in Chemistry, round out 150 years of the incremental advances in our chemical understanding of morphine...

This paper identifies the principal concerns of indigenous peoples with regard to current international treaties on certain psychoactive substances and policies to control and eradicate their production, trafficking, and sale. Indigenous peoples have a specific interest in the issue since their traditional lands have become integrated over time into the large-scale production of coca, opium poppy, and cannabis crops, in response to high demand from the American and European markets, among others. As a consequence, indigenous peoples are persecuted because of their traditional use of these and other plant-based narcotics and hallucinogens...

BACKGROUND: Mass drug administration of praziquantel is the World Health Organization's endorsed control strategy for schistosomiasis. A decade of annual treatments across sub-Saharan Africa has resulted in significant reductions of infection prevalence and intensity levels, although 'hotspots' remain. Repeated drug treatments place strong selective pressures on parasites, which may affect life-history traits that impact transmission dynamics. Understanding drug treatment responses and the evolution of such traits can help inform on how to minimise the risk of drug resistance developing, maximise sustainable control programme success, and improve diagnostic protocols...

Research interest in Wolbachia is growing as new discoveries and technical advancements reveal the public health importance of both naturally occurring and artificial infections. Improved understanding of the Wolbachia bacteriophages (WOs) WOcauB2 and WOcauB3 [belonging to a sub-group of four WOs encoding serine recombinases group 1 (sr1WOs)], has enhanced the prospect of novel tools for the genetic manipulation of Wolbachia. The basic biology of sr1WOs, including host range and mode of genomic integration is, however, still poorly understood...

BACKGROUND: Profiles of DNA methylation of many tissues relevant in human disease have been obtained from microarrays and are publicly available. These can be used to generate maps of chromatin compartmentalization, demarcating open and closed chromatin across the genome. Additionally, large sets of genome-wide transcription factor binding profiles have been made available thanks to ChIP-seq technology. METHODS: We have identified genomic regions with altered chromatin compartmentalization in prostate adenocarcinoma tissue relative to normal prostate tissue, using DNA methylation microarray data from The Cancer Genome Atlas...

Zoonotic diseases are a major cause of morbidity, and productivity losses in both human and animal populations. Identifying the source of food-borne zoonoses (e.g. an animal reservoir or food product) is crucial for the identification and prioritisation of food safety interventions. For many zoonotic diseases it is difficult to attribute human cases to sources of infection because there is little epidemiological information on the cases. However, microbial strain typing allows zoonotic pathogens to be categorised, and the relative frequencies of the strain types among the sources and in human cases allows inference on the likely source of each infection...

Eating poppy seeds can cause a positive urine drug screen, but it is unknown whether ingesting large quantities can result in opiate intoxication or toxicity. A 54-year-old woman with intractable vomiting was found unresponsive at home and later pronounced dead. At autopsy, a cast-like large bowel obstruction composed of poppy seeds was identified. Postmortem blood morphine level was < 10 ng/mL. Cause of death was determined to be complications of a bowel obstruction secondary to poppy seed ingestion. Deaths related to eating poppy seeds have not been described in the literature...
