What Role Does Striatal Dopamine Play in Goal-directed Action?

Evidence suggests that dopamine activity provides a US-related prediction error for Pavlovian conditioning and the reinforcement signal supporting the acquisition of habits. However, its role in goal-directed action is less clear. There are currently few studies that have assessed dopamine release as animals acquire and perform self-paced instrumental actions.

Stimulus-outcome associations are required for the expression of specific Pavlovian-instrumental transfer.

A series of experiments employed a specific Pavlovian-instrumental transfer (PIT) task in rats to determine the capacity of various treatments to undermine two outcome-specific stimulus-outcome (S-O) associations. Experiment 1 tested a random treatment, which involved uncorrelated presentations of the two stimuli and their predicted outcomes. This treatment disrupted the capacity of the outcome-specific S-O associations to drive specific PIT.

Fatal sepsis from appendicitis caused by an impacted tooth.

Acute appendicitis is one of the most common causes of acute abdominal pain globally. The pathophysiology of acute appendicitis is due to occlusion of the appendiceal lumen commonly from a faecolith. Obstruction of the appendiceal lumen by ingested foreign bodies is possible albeit rare.

What does dopamine release reveal about latent inhibition?

A recent paper by Kutlu et al. (2022) argues that changes in dopamine release during stimulus pre-exposure reflect non-associative changes in attention to the conditioned stimulus that are causally related to latent inhibition effects. Associative accounts of pre-exposure-induced changes in associability suggest, however, that such conclusions may be premature.

The positive valence system, adaptive behaviour and the origins of reward.

Although the hey-day of motivation as an area of study is long past, the issues with which motivational theorists grappled have not grown less important: i.e. the development of deterministic explanations for the particular tuning of the nervous system to specific changes in the internal and external environment and the organisation of adaptive behavioural responses to those changes.

Response-independent outcome presentations weaken the instrumental response-outcome association.

The present article explored the fate of previously formed response-outcome associations when the relation between R and O was disrupted by arranging for O to occur independently of R. In each of three experiments response independent outcome delivery selectively reduced the R earning that O. Nevertheless, in Experiments 1 and 2, the R continued to show sensitivity to outcome devaluation, suggesting that the strength of the R-O association was undiminished by this treatment.

Beware the pancreatic incidentaloma in colorectal tumours: pancreatic adenocarcinoma with metastases to the colon and rectum.

Colorectal cancer (CRC) is the third most diagnosed malignancy in the Western world. Routine staging of CRC often identifies incidental lesions on cross-sectional imaging. Appropriate treatment is dependent on a correct histological diagnosis.

Skill decay following Basic Life Support training: a systematic review protocol.

Introduction: Survival from out of hospital cardiac arrest (OHCA) is lower in the UK than in several developed nations. Bystander cardiopulmonary resuscitation (CPR) is associated with increased rates of survival to hospital discharge following OHCA, prompting the introduction of several initiatives by the UK government to increase rates of bystander CPR, including the inclusion of Basic Life Support (BLS) teaching within the English national curriculum. While there is clear benefit in this, increasing evidence suggests poor retention of skills following BLS teaching.

Applications of Deep Mutational Scanning in Virology.

Several recently developed high-throughput techniques have changed the field of molecular virology. For example, proteomics studies reveal complete interactomes of a viral protein, genome-wide CRISPR knockout and activation screens probe the importance of every single human gene in aiding or fighting a virus, and ChIP-seq experiments reveal genome-wide epigenetic changes in response to infection. Deep mutational scanning is a relatively novel form of protein science which allows the in-depth functional analysis of every nucleotide within a viral gene or genome, revealing regions of importance, flexibility, and mutational potential.

PUblications Metadata Augmentation (PUMA) pipeline.

Cohort studies collect, generate and distribute data over long periods of time - often over the lifecourse of their participants. It is common for these studies to host a list of publications (which can number many thousands) on their website to demonstrate the impact of the study and facilitate the search of existing research to which the study data has contributed. The ability to search and explore these publication lists varies greatly between studies.

Privacy preserving data visualizations.

Data visualizations are a valuable tool used during both statistical analysis and the interpretation of results as they graphically reveal useful information about the structure, properties and relationships between variables, which may otherwise be concealed in tabulated data. In disciplines like medicine and the social sciences, where collected data include sensitive information about study participants, the sharing and publication of individual-level records is controlled by data protection laws and ethico-legal norms. Thus, as data visualizations - such as graphs and plots - may be linked to other released information and used to identify study participants and their personal attributes, their creation is often prohibited by the terms of data use.

The role of sodium thiocyanate supplementation during dextran sodium sulphate-stimulated experimental colitis.

Ulcerative colitis is a condition characterised by the infiltration of leukocytes into the gastrointestinal wall. Leukocyte-MPO catalyses hypochlorous acid (HOCl) and hypothiocyanous acid (HOSCN) formation from chloride (Cl) and thiocyanous (SCN) anions, respectively. While HOCl indiscriminately oxidises biomolecules, HOSCN primarily targets low-molecular weight protein thiols.

The gene for the lysosomal protein LAMP3 is a direct target of the transcription factor ATF4.

Autophagy and lysosomal activities play a key role in the cell by initiating and carrying out the degradation of misfolded proteins. Transcription factor EB (TFEB) functions as a master controller of lysosomal biogenesis and function during lysosomal stress, controlling most but, importantly, not all lysosomal genes. Here, we sought to better understand the regulation of lysosomal genes whose expression does not appear to be controlled by TFEB.

Environmental Enrichment From Birth Impacts Parvalbumin Expressing Cells and Wisteria Floribunda Agglutinin Labelled Peri-Neuronal Nets Within the Developing Murine Striatum.

Environmental enrichment can dramatically affect both the development and function of neural circuits. This is accomplished, at least in part, by the regulation of inhibitory cellular networks and related extracellular matrix glycoprotein structures known as perineuronal nets. The degree to which enhanced housing can influence brain areas involved in the planning and execution of actions is not well known.

Direct access surgery for cholecystectomy - can we speed up the process?

Background: In appropriate patients, direct referral from general practitioners to surgery without pre-operative clinic assessment can streamlining the process and allow more efficient use of clinical time. This study aimed to look at the feasibility of a direct access cholecystectomy pathway in patients with symptomatic gallstones and their satisfaction of it.

Methods: In 2012, Bay of Plenty general practitioners (GP) were invited to refer fit patients (ASA 1 or 2, BMI <35 and <60 years old) with symptomatic cholelithiasis directly to a surgical list.

Environmental Enrichment Expedites Acquisition and Improves Flexibility on a Temporal Sequencing Task in Mice.

Environmental enrichment (EE) via increased opportunities for voluntary exercise, sensory stimulation and social interaction, can enhance the function of and behaviours regulated by cognitive circuits. Little is known, however, as to how this intervention affects performance on complex tasks that engage multiple, definable learning and memory systems. Accordingly, we utilised the Olfactory Temporal Order Discrimination (OTOD) task which requires animals to recall and report sequence information about a series of recently encountered olfactory stimuli.

Smart Clothing for Falls Protection and Detection: User-Centred Co-Design and Feasibility Study.

The prevalence and impact of hip fractures on the health and wealth of nations is a global problem and source of health inequalities. This paper reports on the co-design and feasibility testing of a new range of protective, smart clothing. The feasibility of research in a population of older adults in supported living is explored, as are the conceptualisation and measurement of adherence.

α9-nAChR knockout mice exhibit dysregulation of stress responses, affect and reward-related behaviour.

The α9α10-subtype of nicotinic acetylcholine receptor (nAChR) has recently garnered interest in biomedicine and is being pursued as an analgesic target. However, the receptor exhibits diverse tissue distribution, the function of which is known to varying degrees, and targeting this receptor for clinical treatments without a broad understanding of its function may have adverse consequences. The α9α10-nAChR is expressed in the adrenal and pituitary glands, suggesting a potential role in the stress response, but little is known about its function in this tissue.
