PLASMA TRACE ELEMENTS IN MANAGED HUMBOLDT PENGUINS () FROM A SINGLE ZOOLOGICAL COLLECTION IN GERMANY.

Only limited data on concentrations of trace elements in the blood of avian species have been published. This information can play an important role in the conservation of endangered species and their protection from environmental pollutants and can also be clinically relevant in managed individuals. Some elements are essential for the health of the animals in human care, but little is known about expected concentrations for some of these elements.

Capillary Zone Electrophoresis in Humboldt Penguins ().

Electrophoresis is a useful diagnostic tool for detecting inflammation, including inflammation associated with infectious diseases (eg, aspergillosis in penguins). To our knowledge, reference intervals are not available for plasma proteins via electrophoresis in Humboldt penguins (). Therefore, preliminary reference intervals for blood plasma proteins measured by capillary zone electrophoresis were calculated for Humboldt penguins from a single zoological collection, and possible differences between the sexes and the ages of the birds were evaluated.

Validation of the predictive value of BDNF -87 methylation for antidepressant treatment success in severely depressed patients-a randomized rater-blinded trial.

Background: Brain-derived neurotrophic factor (BDNF) is essential for antidepressant treatment of major depressive disorder (MDD). Our repeated studies suggest that DNA methylation of a specific CpG site in the promoter region of exon IV of the BDNF gene (CpG -87) might be predictive of the efficacy of monoaminergic antidepressants such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and others. This trial aims to evaluate whether knowing the biomarker is non-inferior to treatment-as-usual (TAU) regarding remission rates while exhibiting significantly fewer adverse events (AE).

Clinical Chemistry and Haematology Values of a Captive Population of Humboldt Penguins ().

Reference intervals for clinical chemistry and haematology analytes are essential for the interpretation of blood results, but limited data are available for Humboldt penguins () in zoological collections as well as in the wild. The aim of the present study was therefore to establish reference intervals for a series of clinical chemistry and haematology analytes in a single zoological population of Humboldt penguins. Furthermore, possible variations of the analytes influenced by the age and sex of the individuals were investigated.

Nutrient-regulated control of lysosome function by signaling lipid conversion.

Lysosomes serve dual antagonistic functions in cells by mediating anabolic growth signaling and the catabolic turnover of macromolecules. How these janus-faced activities are regulated in response to cellular nutrient status is poorly understood. We show here that lysosome morphology and function are reversibly controlled by a nutrient-regulated signaling lipid switch that triggers the conversion between peripheral motile mTOR complex 1 (mTORC1) signaling-active and static mTORC1-inactive degradative lysosomes clustered at the cell center.

Phosphatidylinositol 3,5-bisphosphate facilitates axonal vesicle transport and presynapse assembly.

Neurons relay information via specialized presynaptic compartments for neurotransmission. Unlike conventional organelles, the specialized apparatus characterizing the neuronal presynapse must form de novo. How the components for presynaptic neurotransmission are transported and assembled is poorly understood.

Using enterprise risk management to strengthen organisational resiliency : One institution's story.

This paper discusses how Carnegie Mellon University launched a cyclical enterprise risk management framework that incorporates both emergency preparedness and response and business continuity into its purview, to deliver greater organisational resiliency. The paper goes on to describe the governance structure that defines roles and responsibilities throughout the organisation, before discussing how faculty, staff and students are engaged and educated to sense risks, and to collaborate with leadership at all levels in prioritising risks for deep-dive assessments and employing feedback loops to support continuous process improvement. As the paper will show, these cyclical practices support organisational resiliency and a greater sense of risk consciousness.

E-Health intervention for subthreshold depression: Reach and two-year effects of a randomized controlled trial.

Background: There is evidence for e-Health interventions for full-blown depression. Little is known regarding commonly untreated subthreshold depression in primary care. This randomized controlled multi-centre trial assessed reach and two-year-effects of a proactive e-Health intervention (ActiLife) for patients with subthreshold depression.

Comparison of Plasma Trace Elements Between 2 Captive Humboldt Penguin () Populations.

Environmental pollutants and their effect on wildlife health play an important role in the conservation of endangered species and can be clinically relevant in captive animals too. Data on relevant concentrations of trace elements in captive birds with no known exposures are rare. For this study, silver, arsenic, gold, barium, cadmium, cobalt, chromium, copper, iron, mercury, magnesium, manganese, molybdenum, thallium, selenium, and zinc were measured by inductively coupled plasma mass spectrometry in lithium heparinized plasma samples from 18 Humboldt penguins at 2 zoological collections in Germany.

PLASMA VITAMIN AND MINERAL CONCENTRATIONS IN CAPTIVE GREATER FLAMINGOS () AS INFLUENCED BY DIET CHANGE.

The greater flamingo () is often maintained in managed care. Although values for plasma concentrations of minerals and vitamins have been published for this species, limited studies investigate the effects of diet changes on these values. Plasma concentrations of selected vitamins (A [and the provitamin A carotenoid β-carotene] and E), minerals (Ca, Cu, Fe, K, Mg, Mn, Na, inorganic P, Se, and Zn), and total protein (TP) were measured in a zoo collection of greater flamingos in November 2018 (n = 48) and in November 2019 (n = 52), 30 d after a change from the summer diet, which was the same in both years, to different winter diets.

COMPARISON OF CLINICAL CHEMISTRY ANALYTES IN GREATER FLAMINGOS () AND AMERICAN FLAMINGOS () IN A ZOO IN EUROPE.

Reference intervals for clinical chemistry analytes are important for the interpretation of blood results, but reference intervals available in journal articles for specific flamingo collections are often based on a small number of individuals or are only available for a limited number of analytes. Differences in husbandry and nutritional conditions may impact reference intervals. The goal of this study was to establish reference intervals from a mixed population of greater () and American () flamingos when husbandry parameters are equal and to compare the results between the different species, sexes, and age groups in order to evaluate differences between these factors.

Engineering living and regenerative fungal-bacterial biocomposite structures.

Engineered living materials could have the capacity to self-repair and self-replicate, sense local and distant disturbances in their environment, and respond with functionalities for reporting, actuation or remediation. However, few engineered living materials are capable of both responsivity and use in macroscopic structures. Here we describe the development, characterization and engineering of a fungal-bacterial biocomposite grown on lignocellulosic feedstocks that can form mouldable, foldable and regenerative living structures.

A pilot study on dietary and faecal calcium/phosphorus ratios in different types of captive ruminating herbivores.

Quantitative differences in calcium and phosphorus metabolism between domestic species exist and can be visualised using data on calcium and phosphorus intake and faecal excretion. The parameter for analysing the results was defined as Δ = dietary calcium/phosphorus (Ca/P) ratio - faecal Ca/P ratio. In previous studies, hindgut fermenters had significantly higher Δ values than ruminants (sheep, cattle, goats), which was explained by the high calcium digestibilities in hindgut fermenters in contrast to highly efficient phosphorus recycling in ruminants.

Comparison of Capillary Zone Electrophoresis in Greater Flamingos () and American Flamingos ().

Electrophoresis can be used to aid in the diagnosis of infectious diseases (eg, aspergillosis) in avian species. Reference intervals for blood plasma proteins of 2 different flamingo species ( and ) and their hybrids were calculated by capillary zone electrophoresis (CZE) and differences between these species, sexes, and age groups were evaluated. Lithium-heparinized plasma samples from 111 animals from a zoological collection were analyzed by CZE and statistically evaluated.

Topical treatment of multiple erosive, ulcerative skin lesions in an Indian rhinoceros (Rhinoceros unicornis).

A 30-year-old, intact female Indian rhinoceros () was presented with ongoing erosive, ulcerative skin lesions over a 4-year-period. The lesions appeared to be non-pruritic and non-seasonal. A systemic antibiotic therapy had been unsuccessful.

Rapid and simultaneous screening of pathway designs and chassis organisms, applied to engineered living materials.

Achieving a high product titer through pathway optimization often requires screening many combinations of enzymes and genetic parts. Typically, a library is screened in a single chassis that is a model or production organism. Here, we present a technique where the library is first introduced into B.

Neuronal Autophagy Regulates Presynaptic Neurotransmission by Controlling the Axonal Endoplasmic Reticulum.

Neurons are known to rely on autophagy for removal of defective proteins or organelles to maintain synaptic neurotransmission and counteract neurodegeneration. In spite of its importance for neuronal health, the physiological substrates of neuronal autophagy in the absence of proteotoxic challenge have remained largely elusive. We use knockout mice conditionally lacking the essential autophagy protein ATG5 and quantitative proteomics to demonstrate that loss of neuronal autophagy causes selective accumulation of tubular endoplasmic reticulum (ER) in axons, resulting in increased excitatory neurotransmission and compromised postnatal viability in vivo.

Effect of a 1-year short message service in detoxified alcohol-dependent patients: a multi-center, open-label randomized controlled trial.

Background And Aims: Existing evidence suggests that text message interventions can help people to reduce their alcohol consumption. However, studies with alcohol-dependent patients are lacking. In this study a 1-year automatic mobile phone-based short messaging service (SMS) intervention on alcohol consumption in patients after alcohol detoxification in hospital was compared with treatment as usual.

Toxoplasma gondii in small exotic felids from zoos in Europe and the Middle East: serological prevalence and risk factors.

Background: Toxoplasma gondii infections and cases of clinical toxoplasmosis have been recorded in zoo animals. Wild felids in human care can serve as definitive hosts that shed oocysts, but also as intermediate hosts for the parasite. Some felid species, such as the Pallas's cat (Otocolobus manul) or sand cat (Felis margarita), may suffer from clinically apparent toxoplasmosis.

Evaluation of algorithm development approaches: Development of biomarker panels for early detection of colorectal lesions.

Introduction: Colorectal cancer (CRC) is the third most common cancer in the U.S. Early detection of CRC can substantially increase survival rates.

Feasibility and Acceptability of an Intervention Providing Computer-Generated Tailored Feedback to Target Alcohol Consumption and Depressive Symptoms in Proactively Recruited Health Care Patients and Reactively Recruited Media Volunteers: Results of a Pilot Study.

Background: A pre-post pilot study was conducted to test the feasibility, acceptability, and potential effectiveness of a fully automatized computer-based intervention targeting hazardous drinking and depressiveness in proactively recruited health care patients (HCPs). To address the importance of the sample selection when testing interventions, HCPs were compared to media recruited volunteers (MVs).

Method: In a multicenter screening program 2,773 HCPs were screened for hazardous drinking and depressive symptoms.

Validation of a novel model for the early detection of hepatocellular carcinoma.

Background: The biomarkers alpha-fetoprotein (AFP) and protein induced by vitamin K absence/antagonist-II (PIVKA-II) may be useful for detecting early-stage hepatocellular carcinoma (HCC). We evaluated the performance of AFP and PIVKA-II levels, alone and in combination with clinical factors, for the early detection of HCC.

Methods: In a case-control study, serum AFP and PIVKA-II were measured using the ARCHITECT immunoassay analyzer system in a cohort of 119 patients with HCC, 215 patients with non-malignant liver disease, and 34 healthy subjects.

The inverse link between genetic risk for schizophrenia and migraine through NMDA (N-methyl-D-aspartate) receptor activation via D-serine.

Schizophrenia has a considerable genetic background. Epidemiological studies suggest an inverse clinical association between schizophrenia and migraine. However, it is unclear to what extent this inverse comorbidity can be explained by genetic mechanisms or by schizophrenia-related behavioral factors.
