Introduction: Emerging and re-emerging infectious diseases continue to pose a severe threat to public health in Sub-Saharan Africa (SSA) and globally. Community-related interventions, such as community e-Health literacy, can contribute to the preparedness to respond effectively to emerging and re-emerging infectious diseases. This study investigated the relationship between e-Health literacy and SSA countries' perceptions of the importance of readiness for potential pandemics.

Absence of a Causal Link between Elemental Carbon Exposure and Short-Term Respiratory Toxicity in Human-Derived Organoids and Cellular Models.

Environ Sci Technol

December 2024

Shanghai Key Laboratory of Atmospheric Particle Pollution and Prevention, Department of Environmental Science and Engineering, Fudan University, Shanghai 200433, China.

Black carbon or elemental carbon (EC) in the atmosphere plays an ambiguous role in acute respiratory toxic effects. Here, we evaluate the contribution of EC to the short-term toxicity (including cytotoxicity and oxidative stress potency) of fine particulate matter (PM) on the human respiratory tract using in vitro airway organoids and cell lines. The toxic potency of EC per unit mass, including char and soot, is more than 2 orders of magnitude lower than that of polycyclic aromatic hydrocarbons (PAHs), which are coemitted from incomplete combustion.

Monoclonal gammopathy of undetermined significance (MGUS) is a pre-malignant condition of multiple myeloma (MM). Evidence suggested old age, black race, male gender, and obesity as risk factors for MGUS development; however, whether they are associated with an increased risk of progression to MM among patients with MGUS is unclear. A systematic search of PUBMED and EMBASE for cohort studies investigating the association between age/race/gender/obesity and progression to MM.

Zoological Medicine, Department of Clinical Sciences, Faculté de Médecine Vétérinaire, Université de Montréal, St Hyacinthe, Canada. Electronic address:

Fish represent the most common companion exotic animal in the United States and Canada in number of individuals and hold the third place after dogs and cats in terms of the number of households. Beyond companion animals, fish gastrointestinal diseases are particularly relevant for the aquaculture industry as feeding represents about 50% to 70% of the costs associated with fish production. Thus, nutrient malabsorption may have dramatic consequences both for the fish health and body condition score, but also for farmers.

Update on the connectivity of the paraventricular nucleus of the thalamus and its position within limbic corticostriatal circuits.

Neurosci Biobehav Rev

December 2024

Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, Manitoba, R3E 0W2, Canada. Electronic address:

The paraventricular nucleus of the thalamus (PVT) is generating interest because of evidence establishing a role for this midline thalamic nucleus in behavior. Early tracing studies demonstrated that afferent fibers from the PVT and limbic cortex converge with dopamine fibers within subcompartments of the ventral striatum. Subsequent tracing studies expanded on these observations by establishing that the PVT provides a dense projection to a continuum of striatal-like regions that include the nucleus accumbens and the extended amygdala.

University of Novi Sad, Faculty of Sciences, Department of Chemistry, Biochemistry and Environmental Protection, Trg Dositeja Obradovica 3, 21000 Novi Sad, Serbia.

This study investigates the environmental risks posed by heavy metals in sediment from the Great Bačka Canal using both active and passive sampling methods. The necessity of this research lies in the critical need to address sediment contamination in ecological hotspots and enhance sediment management practices. Active sampling revealed total heavy metal concentrations, while sequential extraction showed bioavailability varied across metal fractions.

Nose-to-brain delivery of lithium via a sprayable in situ-forming hydrogel composed of chelating starch nanoparticles.

J Control Release

December 2024

Department of Chemical Engineering, McMaster University, 1280 Main Street, West Hamilton, ON L8S 4L8, Canada. Electronic address:

While bipolar disorder patients can benefit from lithium therapy, high levels of lithium in the serum can induce undesirable systemic side effects. Intranasal (IN) lithium delivery offers a potential solution to this challenge given its potential to facilitate improved lithium transport to brain when delivered to the olfactory mucosa. Herein, a sprayable, in situ forming nanoparticle network hydrogel (NNH) based on Schiff base interactions between chelator-functionalized oxidized starch nanoparticles (SNPs) and carboxymethyl chitosan (CMCh) is reported that can be deployed within the nasal cavity to release ultra-small penetrative SNPs over time.

Perceived fatigue does not alter effort-based decision making but does undermine confidence in the ability to perform physical actions.

Physiol Behav

December 2024

Cardiff University Brain Research Imaging Centre (CUBRIC), Cardiff University, Cardiff, UK; Department of Neuroscience, Brighton and Sussex Medical School, University of Sussex, UK.

Fatigue may affect the decision to deploy effort (cost) for a given rewarded outcome (benefit). However, it remains unclear whether these fatigue-associated changes can be attributed to simply feeling fatigued. To investigate this question, twenty-two healthy males made a series of choices between two rewarded options: a fixed, no effort option, where no physical effort was required to obtain a set, low reward vs.

Institute of Pharmaceutical Sciences, University of Freiburg, 79104 Freiburg im Breisgau, Germany; Andreas Hettich GmbH & Co. KG, 78532 Tuttlingen, Germany.

Thermosensitive liposomes (TSLs) have great potential for the selective delivery of cytostatic drugs to the tumor site with greatly reduced side effects. Here we report the discovery and characterization of new thermosensitive small multilamellar lipid nanoparticles (tSMLPs) with unusually high temperature selectivity. Furthermore, the temperature-dependent release of the fluorescent marker calcein from tSMLPs is enhanced by human serum albumin.

Exposure to Perinatal Trauma Modifies Nociception and Gene Expression in the Prefrontal Cortex and Hypothalamus of Adolescent Rats.

J Pain

December 2024

Department of Neuroscience, School of Translational Medicine, Monash University, Melbourne, Victoria, Australia. Electronic address:

The perinatal period encompasses a critical window for neurodevelopment that renders the brain highly responsive to experience. Trauma, such as intimate partner violence (IPV) and early life stress/neglect, during this period negatively affects physical and mental health outcomes, including increasing ones risk for chronic pain. Although epigenetic programming likely contributes, the mechanisms that drive the relationship between perinatal trauma and adverse health outcomes, are not fully understood.
