Abattoir surveys and findings from post-mortem meat inspection are commonly used to estimate infection or disease prevalence in farm animal populations. However, the function of an abattoir is to slaughter animals for human consumption, and the collection of information on animal health for research purposes is a secondary objective. This can result in methodological shortcomings leading to biased prevalence estimates. Selection bias can occur when the study population as obtained from the abattoir is not an accurate representation of the target population...

The DGT technique (diffusive gradients in thin films) is widely used for passive sampling of labile trace metals and metalloids in natural waters. Although development of fouling on the protective membranes is frequently observed, its effect on DGT sampling has been barely investigated. This study evaluates the influence of fouling on sampling of trace cationic metals Cd(II), Cu(II), Ni(II) and Pb(II) and oxyanions As(V), Cr(VI), Sb(V) and Se(VI). Fouling was developed in situ on polycarbonate membranes in four diverse natural freshwater environments and sampling alteration was assessed in controlled laboratory experiments...

New stationary phases are continuously developed for achieving higher efficiencies and unique selectivities. The performance of any new phase can only be assessed when the columns are effectively packed under high pressure to achieve a stable bed. The science of packing columns with stationary phases is one of the most crucial steps to achieve consistent and reproducible high-resolution separations. A poorly packed column can produce non-Gaussian peak shapes and lower detection sensitivities. Given the ever larger number of stationary phases, it is impossible to arrive at a single successful approach...

We computed the channels of the 3A4 isoform of the cytochrome P450 3A4 (CYP) on the basis of 24 crystal structures extracted from the Protein Data Bank (PDB). We identified three major conformations (denoted C, O1 and O2) using an enhanced version of the CCCPP software that we developed for the present work, while only two conformations (C and O(2) ) are considered in the literature. We established the flowchart of definition of these three conformations in function of the structural and physicochemical parameters of the ligand...

New Australian and New Zealand Neonatal Resuscitation guidelines reflect recent advances in neonatal resuscitation science, as critically appraised by the International Liaison Committee on Resuscitation. Substantial changes since the 2010 guidelines include: (i) updates to the Newborn Resuscitation Flowchart to include a greater emphasis on maintaining normal body temperature, and to emphasise the importance of beginning assisted ventilation by 1 min in infants who have absent or ineffective spontaneous breathing; (ii) updates to the physiology of the normal perinatal transition that resuscitation is trying to restore; (iii) recommendations for more frequent reinforcement of training, and for structured feedback for resuscitation training instructors; (iv) new guidance in relation to the timing of cord clamping for preterm newborn infants; (v) recommendation to monitor body temperature on admission to newborn units as a resuscitation quality indicator; (vi) suggestion to consider electrocardiographic (ECG) monitoring (as an adjunct to oximetry) to obtain more rapid and accurate estimation of heart rate during resuscitation; (vii) removal of previous suggestions to intubate meconium-exposed, non-vigorous term infants to suction the trachea; and (viii) suggestion to establish vascular access to enable administration of intravenous adrenaline (epinephrine) as soon as chest compressions are deemed to be needed...

The ACR Incidental Findings Committee (IFC) presents recommendations for renal masses that are incidentally detected on CT. These recommendations represent an update from the renal component of the JACR 2010 white paper on managing incidental findings in the adrenal glands, kidneys, liver, and pancreas. The Renal Subcommittee, consisting of six abdominal radiologists and one urologist, developed this algorithm. The recommendations draw from published evidence and expert opinion and were finalized by informal iterative consensus...

Posterior shoulder instability is recognised as being less prevalent than anterior instability, however the diagnosis of this pathology is easily overlooked or missed and this may contribute to an underestimation of prevalence. Recently, there has been increasing recognition of this condition and consequently a greater requirement for knowledge of diagnostic procedures and treatment directions. Currently there is limited research into the conservative management of posterior instability, although it is recommended as first-line treatment prior to surgical review, particularly in those with an atraumatic instability mechanism...

This is the second of two papers reporting the results of a major study considering 'operator models' for municipal solid waste management (MSWM) in emerging and developing countries. Part A documents the evidence base, while Part B presents a four-step decision support system for selecting an appropriate operator model in a particular local situation. Step 1 focuses on understanding local problems and framework conditions; Step 2 on formulating and prioritising local objectives; and Step 3 on assessing capacities and conditions, and thus identifying strengths and weaknesses, which underpin selection of the operator model...

RATIONALE: Species identification of hair is routinely done by microscopic analysis. Following previous studies that used protein analysis to characterize species markers in hair and wool, the present work aims at covering a larger number of species and to ultimately offer a method for rapid hair identification in forensics and archaeology. METHODS: Hair is mostly made of alpha-keratins; these proteins have only been sequenced in a handful of species and most animal families are under-represented...

REVIEW
Peter Vock
Imaging during pregnancy has increased in frequency. Radiation protection is extremely important although tissue reactions of the conceptus, requiring a threshold dose of around 100mGy, are unlikely in the diagnostic use of X-rays and stochastic effects of cancerogenesis have a rather low risk (around 10(-4)/mGy for childhood cancer due to in utero exposure). This article will review the risk depending on dose and phase of pregnancy and the exposure by frequent examinations; it will then concentrate on the duties of an imaging department: screening for pregnancy, examination justification, planning and optimization, patient information, counseling, involving the patient in the decisions, and managing the situation of pregnant staff members...

BACKGROUND: The number of hemodialysis patients has been progressively increasing in our country. On the other hand, chronic hip arthropathy associated with long-term hemodialysis is a devastating problems affecting patients' quality of life. In our previous study, we proposed a classification system for radiological abnormalities seen in hemodialysis-related hip lesions. The purpose of the study was to propose the surgical strategy for hip disorders caused by long-term hemodialysis. METHODS: Patients with a history of hemodialysis for more than 10 years, 191 hip lesions in 165 consecutive patients who visited our institute due to hip symptoms...

BACKGROUND: Multimorbidity results in complex polypharmacy which may bear a risk of drug interactions. A better understanding of opioid analgesics combination therapy used for pain management could help warrant medication safety, efficacy, and economic relevance. Until now there has been no review summarizing the opioid analgesics-related pharmacokinetic drug interactions from the perspective of evidence based on randomized controlled trials (RCTs). METHOD: A literature search was performed using PubMed, MEDLINE, and the Cochrane Library, using a PRISMA flowchart...

A particular approach to the task of energy conversion of a residual waste material was properly experienced during the implementation of the national funded Enerpoll project. This project is a case study developed in the estate of a poultry farm that is located in a rural area of central Italy (Umbria Region); such a farm was chosen for the research project since it is almost representative of many similar small-sized breeding realties of the Italian regional context. The purpose of the case study was the disposal of a waste material (i...

This study focuses on the correlation investigation between rheological and physical parameters and how it can contribute to optimize the topical formulations development. A gel and an emulgel containing pinhão derivatives, and their respective controls, were analyzed along six months of storage. A flowchart of analyses was proposed to use in topical formulation development when a benchmark is the goal or when it is necessary to change some raw material. All formulations were stable over the storage time and the formulations containing pinhão starch and coat extract presented similar properties to those of the control formulations...

The determination of the post-mortem interval (PMI) of skeletal remains is a challenging aspect in the forensic field. Previous studies focused their attention on different macroscopic and morphological aspects but a thorough and complete evaluation of the potential of chemical and physical analyses in this field of research has not been performed. In addition to luminol test and Oxford histology index (OHI) reported in a recent paper, widely spread and accessible methods based on physical aspect and chemical characteristics of skeletal remains have been investigated as potential alternatives to dating by determination of (14)C...

PURPOSE: To describe a standard approach to manage tear dysfunction (TD), in order to obtain a clinically favourable outcome. TD is a highly prevalent, yet largely underdiagnosed, condition that affects from 5 to 30% of the population above 50 years old. Left untreated, TD is associated with eye discomfort and ocular surface disease, substantially affecting quality of life. Although the prevalence of this problem is increasing significantly, a standard approach to its prevention and treatment is not available yet...
