Unsustainable wildlife trade affects biodiversity and the livelihoods of communities dependent upon those resources. Wildlife farming has often been proposed to promote sustainable trade but characterizing markets and understanding consumer behaviour remain neglected, but essential, steps with important implications for its design and evaluation. We used sea turtle trade in the Cayman Islands as a case study - where turtle meat for consumption has been produced for almost 50 years, to explore consumer preferences towards wild-sourced (illegal) and farmed (legal) products and potential conservation implications...

Chloroquine (CQ) induces histamine-independent itch in human and mice. We recently reported the role of intradermal nitric oxide (NO)/ cyclic guanosine monophosphate (cGMP) pathway in CQ-evoked scratching in mice. Chloroquine stimulates neuronal nitric oxide synthase (nNOS) activity to over-producing NO in the skin. Sumatriptan, a 5-hydroxytryptamine 1b/1d receptors (5-HTR1b/1d) agonist, is involved in pain and used to treat migraine and cluster headaches. According to previous studies, sumatriptan inhibits NOS activity...

BACKGROUND: Impulsive decision making relates to problematic substance use. Specifically, altered delay discounting has been suggested as a behavioral marker for addiction, while other relevant facets of choice impulsivity such as probability discounting or loss aversion are clearly understudied. METHODS: Two studies were performed collecting behavioral data on choice impulsivity with a value-based decision-making battery providing estimates of delay discounting, probability discounting for gains and losses, and loss aversion...

Skin biopsies from patients with neuropathic pain often show changes in epidermal innervation, although it remains to be elucidated to what extent such changes can be linked to a particular subgroup of nerve fibers and how these changes are correlated with pain intensity. Here, we investigated to what extent behavioral signs of hyperalgesia are correlated with immunohistochemical changes of peptidergic and non-peptidergic epidermal nerve fibers in a rat model of nerve injury-induced pain. Rats subjected to unilateral partial ligation of the sciatic nerve developed significant mechanical and thermal hyperalgesia as tested by the withdrawal responses of the ipsilateral footpad to von Frey hairs and hotplate stimulation...

Olfactory sensory neurons (OSNs) are chemoreceptors that establish excitatory synapses within glomeruli of the olfactory bulb. OSNs undergo continuous turnover throughout life, causing the constant replacement of their synaptic contacts. Using Xenopus tadpoles as an experimental system to investigate rewiring of glomerular connectivity, we show that novel OSN synapses can transfer information immediately after formation, mediating an olfactory-guided behavior. Tadpoles recover the ability to detect amino acids four days after bilateral olfactory nerve transection...

BACKGROUND: The impact of untreated syphilis during pregnancy on neonatal health remains a major public health threat worldwide. Given the high prevalence of syphilis during pregnancy in Zambia and Democratic Republic of Congo (DRC), the Preventive Congenital Syphilis Trial (PCS Trial), a cluster randomized trial, was proposed to increase same-day screening and treatment of syphilis during antenatal care visits. To design an accepted and feasible intervention, we conducted a qualitative  formative research...

Neuronal damage in primary auditory cortex (A1) underlies complex manifestations of noise exposure, prevention of which is critical for health maintenance. Acid sphingomyelinase (ASM) catalyzes generation of ceramide (Cer) which if over-activated mediates neuronal disorders in various diseases. Tricyclic antidepressants (TCAs), by restraining ASM/Cer, benefits multiple neuronal anomalies, so we aimed to elucidate the effect of TCA on noise induced hearing loss and auditory cortex derangement, unraveling mechanism involved...

BACKGROUND: The first year of university attendance represents a critical time frame for the development of alcohol use and misuse given changes in autonomy and increased access to alcohol. Prior studies have demonstrated that the establishment of drinking patterns during this period is impacted by an array of demographic, environmental, and familial factors. It is critical to consider such factors jointly, and to understand potentially differential effects on stages of alcohol use/misuse, in order to identify robust predictors that may be targeted in prevention and intervention programming...

In vitro evaluations provide vital information on the ability of tissue engineered scaffolds to support cell life and promote natural physiological behaviors in culture. Such assessments are necessary to conduct before implementation of the scaffolds for tissue healing in vivo. The scaffold extracellular matrix must provide the biochemical and mechanical cues necessary to promote cellular attachment, migration and proliferation before differentiation and new tissue deposition can occur. In this study, an in vitro evaluation was conducted to assess the ability of scaffolds 3D printed with a previously developed alginate-polyvinyl alcohol-hydroxyapatite formulation to promote proliferation of encapsulated MC3T3 cells...

BACKGROUND: Evidence suggests that indoor tanning (IT) may have addictive properties. However, many instruments for measuring IT addiction show poor validity and reliability. Recently, a new instrument, the Behavioral Addiction Indoor Tanning Screener (BAITS), has been developed. OBJECTIVES: Our aim was to test validity and reliability of the BAITS by using a multi-method approach. METHODS: We used data of the first wave of the National Cancer Aid Monitoring on Sunbed Use (NCAM), which includes a cognitive pretest (08/2015) and a Germany-wide representative survey (10-12/2015)...

The differential diagnosis of atypical parkinsonian syndromes is challenging. These severe and often rapidly progressive neurodegenerative disorders are clinically heterogeneous and show significant phenotypic overlap. Here we review clinical, imaging, neuropathologic and genetic features of multiple system atrophy (MSA), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and frontotemporal lobar degeneration (FTLD). The terms CBD and FTLD refer to pathologically confirmed cases of corticobasal syndrome (CBS) and frontotemporal dementia (FTD)...

The effects of varying formulation and processing parameters on rheological properties in a model lipid/protein-based emulsion gel were studied. Heat-set model lipoproteic emulsion gels were prepared with varying levels of protein, lipid, and NaCl contents and high pressure homogenization treatments. Small deformation oscillatory rheometry, creep compliance, and pore size analysis experiments were used to characterize intrinsic structural properties, matrix interactions, and microstructure. Creep compliance behavior of the gel system was successfully modeled by a four-component Burgers model...

PURPOSE: The use of liquid ionization chambers can provide useful information to endeavors with radiation dosimetry for highly modulated beams. Liquid ionization chambers may be particularly suitable for computed tomography applications where conventional ionization chambers do not present a high enough sensitivity for the spatial resolution required to characterize common X-ray beams. Due to the sensitivity, which leads to high charge densities, liquid ionization chambers can suffer from large recombination losses leading to degradation in signal to dose rate linearity...

There are about 25.7 million stroke survivors world-wide. Ischemic stroke remains the most common type of stroke. Numerous modifiable risk factors have been identified, including behaviors like cigarette smoking and sedentary lifestyle and treatable medical comorbidities like hypertension, hyperlipidemia and atrial fibrillation. Once considered irreversible, acute ischemic stroke is now amenable to acute medical and endovascular therapies to reduce infarct volume. Many advances are expected in the years to come, particularly in the areas of prevention and recovery...

BACKGROUND: Heavy and chronic ethanol (EtOH) exposure can cause significant structural and functional damage to the adult brain. The most devastating consequence of EtOH exposure is the neurotoxicity associated with the depletion of neurons. Regulation of splice variants in the brain can modulate protein functions, which may ultimately affect behaviors associated with alcohol dependence and EtOH-mediated neurotoxicity. Since alcohol consumption is associated with neurotoxicity, it is possible that altered splicing of survival and pro-survival factors during the development of alcoholism may contribute to the neurotoxicity...

Biofilms are thin layers of bacteria embedded within a slime matrix that live on surfaces. They are ubiquitous in nature and responsible for many medical and dental infections, industrial fouling and are also evident in ancient fossils. A biofilm structure is shaped by growth, detachment and response to mechanical forces acting on them. The main contribution to biofilm versatility in response to physical forces is the matrix that provides a platform for the bacteria to grow. The interaction between biofilm structure and hydrodynamics remains a fundamental question concerning biofilm dynamics...

Correlated motion analysis provides a method for understanding communication between and dynamic similarities of biopolymer residues and domains. The typical equal-time correlation matrices - frequently visualized with pseudo-colorings or heat maps - quickly convey large regions of highly correlated motion but hide more subtle similarities of motion. Here we propose a complementary method for visualizing correlations within proteins (or general biopolymers) that quickly conveys intuition about which residues have a similar dynamic behavior...

BACKGROUND: ARHGEF10, a member of Rho guanine nucleotide exchange factors (GEF) family, stimulates the Rho GTPases. Rho GTPases have been reported to regulate a variety of cellular behaviors such as cell polarity, cytoskeletal organization and gene transcription. ARHGEF10 SNPs are linked with the risk of ischemic stroke. However, the role of ARHGEF10 in platelet function remains unknown. OBJECTIVE: To examine the role of ARHGEF10 in platelet function. METHODS: ARHGEF10 knockout mice were generated...

Protein sequences have evolved to fold into functional structures, resulting in families of diverse protein sequences that all share the same overall fold. One can harness protein family sequence data to infer likely contacts between pairs of residues. In the current study, we combine this kind of inference from coevolutionary information with a coarse-grained protein force field ordinarily used with single sequence input, the Associative memory, Water mediated, Structure and Energy Model (AWSEM), to achieve improved structure prediction...
