Pro-inflammatory IL-1α levels increased during torpor and soluble epidermal growth factor receptor protein levels increased during arousal in BAT. Given their known roles in other model systems, these proteins could regulate processes like adipogenesis, lipid catabolism, or cell motility. Decreased TIMP2 levels combined with maintained MMP2 or MMP3 protein levels suggested that BAT may avoid tissue remodeling until arousal. No changes in WAT inflammatory cytokines or soluble receptors as well as decreased MMP2 levels during torpor and arousal suggested inflammation and modification to the extracellular matrix is likely suppressed in WAT. This study emphasizes the fat-but-fit nature of the hibernating ground squirrel and the ability of its fat stores to suppress inflammation.Coronary heart disease and psychological stress factors such as depression are prevalent and associated with high morbidity/mortality; they are also challenging to manage, especially when treated in isolation of each other. Recent advances support an integrated approach to their management that is built on a foundation of an extensive, multi-component network of neurological structures. In this review, we describe this extensive cardioneural network that encompasses the heart, brain, spinal cord, and ganglia throughout the body, and then discuss ambulatory and laboratory-based non-invasive measures of this network that both measure psychological stress and heart disease severity. Lastly, we discuss their potential transformative clinical and public health applications, and also possible cardioneural interventions such as exercise and biofeedback.Seafood is nutritious and a healthy source of proteins and its regular consumption is highly recommended by medical professionals and dieticians. Owing to this, the global consumption of seafood per capita has been significantly increasing since the 1960s. Consequently, seafood-borne pathogens, including parasites, have also become more widely known and recognised. In Australia, a vast island country, information about such parasites is extremely limited. This study aimed to determine the prevalence and abundance of zoonotic parasites, including anisakid nematodes, in selected Australian edible fish. Four species of fish, namely tiger flathead, Platycephalus richardsoni (n = 43), blue mackerel, Scomber australasicus (n = 117), snapper, Pagrus auratus (n = 11) and school whiting, Sillago flindersi (n = 90) were purchased from a fish market. Although a range of parasites was found, due to their significance for human health, the focus of this study was on nematodes whose infectious stage was found in these fish. The prevalence of nematodes in these fish species was 86.05%, 64.10%, 45.45% and 56.67%, respectively. Among the parasites found, Anisakis spp., Contracaecum spp. and Hysterothylacium spp. in tiger flathead, blue mackerel and school whiting, might be of zoonotic importance. Our findings suggest there is a need to revise current seafood safety protocols and develop educational campaigns for seafood industries stakeholders.Salmonella not only invades host cells, but also replicates intracellularly to cause a range of diseases, including gastroenteritis and systemic infections such as typhoid fever. The body's first line of defense against pathogens is the innate immune response system that can protect against Salmonella invasion and replication. Nuclear factor κB (NF-κB) is an important transcriptional regulator that plays an important role in host inflammatory responses to pathogens. Both the canonical and non-canonical NF-κB signaling pathways are activated by Salmonella in many different ways through its virulence factors, leading to the release of inflammatory factors and the activation of inflammatory responses in mammalian hosts. Equally, Salmonella, as an enteropathogen, has accordingly evolved strategies to disturb NF-κB activation, such as secreting some effector proteins by type III secretion systems as well as inducing host cells to express NF-κB pathway inhibitors, allowing it to colonize and persistently infect the hosts. This review focuses on how Salmonella activates NF-κB signaling pathway and the strategies used by Salmonella to interfere with the NF-κB pathway activation.

For certain vaccines, dosing can be reduced by intradermal (ID) immunization without loss of immunogenicity, as an alternative to standard routes of administration. However, a certain level of dose-sparing might also be achieved by reducing doses of intramuscular (IM) or subcutaneous (SC) vaccines.

We conducted a systematic review comparing identical reduced amounts of antigen delivered by either ID, or IM/SC routes (PROSPERO registration no. GS-9973 mouse CRD42020151725).

Of 6015 articles identified, we included 26 articles, covering eight different vaccines. Equivalent immune responses were demonstrated in 19/26 studies, and 7/26 studies suggested inferior immune responses after IM/SC immunization.

We conclude that fractional dosed IM/SC vaccination is at best as immunogenic, but potentially inferior to ID vaccination. The safety profiles were at large comparable, although minor local adverse events were more common after ID delivery. Future vaccine trials, depending on the platform used, should add a fractional dose IM/SC arm, besides a fractional dose ID arm.

We previously reported that Smad1/5/9 immunoreactivity was observed in astrocytes of various rat brain regions including the hippocampus, suggesting that Smad1/5/9 may be associated with the physiology of astrocytes. However, the Smad1/5/9 expression and activation in the hippocampal astrocytes after global cerebral ischemia has not been yet elucidated. In this study, we examined temporal changes in the expression and phosphorylation of Smad1/5/9 in the hippocampus using a rat model of global cerebral ischemia. Furthermore, we examined the candidate ligand involved in the phosphorylation of Smad1/5/9 in the hippocampus after ischemia. Pyramidal neuronal cell death in the CA1 regions was visible at 3 days, and maximum death occurred within 7 days after ischemia. At 7 days after ischemia, astrocytes that showed strong immunoreactivity for Smad1/5/9 were frequently observed in the CA1 region.
