Doing science in difficult socioeconomic circumstances.

Doing scientific research can be a challenging, but creative and rewarding career. However, the challenge of doing research is orders of magnitude more difficult for scientists lacking access to the necessary resources. Resource-scarce environments are quite common worldwide and are highly contingent on the financial and social climate of one's location. Through the experiences of four scientists, this Perspective explores the challenges associated with doing research in disadvantaged socioeconomic circums...


Evaluating Mice lacking Serum Carboxylesterase as a Behavioral Model for Nerve Agent Intoxication.

Mice and other rodents are typically utilized for chemical warfare nerve agent research. Rodents have large amounts of carboxylesterase in their blood, while humans do not. Carboxylesterase non-specifically binds to and detoxifies nerve agent. The presence of this natural bioscavenger makes mice and other rodents poor models for studies identifying therapeutics to treat humans exposed to nerve agents. To obviate this problem, a serum carboxylesterase knockout (Es1 KO) mouse was created. In this study, Es1 K...

Comprehensive analysis of hippocampal miRNAomes in humans and mice.

This study aims to explore the similarity and difference of hippocampal miRNAomes between humans and mice.


The role of DNA methylation in epigenetics of aging.

Recent research suggests that epigenetics, especially DNA methylation, plays a mechanistic role in aging. Epigenetic clocks, which measure changes in a few hundred specific CpG sites, can accurately predict chronological age in a variety of species, including humans. These clocks are currently the best biomarkers for predicting mortality in humans. Additionally, several studies have characterized the effects of aging across the methylome in a wide variety of tissues from humans and mice. A small fraction (~...

Climate change and One Health.

The journal The Lancet recently published a countdown on health and climate change. Attention was focused solely on humans. However, animals, including wildlife, livestock and pets, may also be impacted by climate change. Complementary to the high relevance of awareness rising for protecting humans against climate change, here we present a One Health approach, which aims at the simultaneous protection of humans, animals and the environment from climate change impacts (climate change adaptation). We postulat...

Smombie Guardian: We watch for potential obstacles while you are walking and conducting smartphone activities.

With the growing dependence on smartphones for everyday activities, a large number of pedestrians nowadays are constantly fixated on their smartphone screens, and hence are susceptible to walking off pavements or colliding with other pedestrians. Reduced attention and situational awareness can render smartphone-occupied users, or smombies, oblivious to potential risks when using their smartphones while walking or driving. In this paper, we introduce a smartphone application, called Smombie Guardian, that de...

Standardizing protocols dealing with growth hormone receptor gene disruption in mice using the Cre-lox system.

Mice and humans with reduced growth hormone (GH) action before birth are conferred positive health- and life-span advantages. However, little work has been performed to study the effect of conditional disruption of GH action in adult life. With this as our objective, we sought to elucidate a reproducible protocol that allows generation of adult mice with a global disruption of the GH receptor (Ghr) gene, using the tamoxifen (TAM)-inducible Cre-lox system, driven by the ROSA26 enhancer/promoter. Here we repo...

Magel2 Modulates Bone Remodeling and Mass in Prader-Willi Syndrome by Affecting Oleoyl Serine Levels and Activity.

Among a multitude of hormonal and metabolic complications, individuals with Prader-Willi syndrome (PWS) exhibit significant bone abnormalities, including decreased BMD, osteoporosis, and subsequent increased fracture risk. Here we show in mice that loss of Magel2, a maternally imprinted gene in the PWS critical region, results in reduced bone mass, density, and strength, corresponding to that observed in humans with PWS, as well as in individuals suffering from Schaaf-Yang syndrome (SYS), a genetic disorder...

Hydrolysis of di(2-ethylhexyl) phthalate in humans, monkeys, dogs, rats, and mice: An in vitro analysis using liver and intestinal microsomes.

Di(2-ethylhexyl) phthalate (DEHP) is a widely used plasticizer that is rapidly metabolized to mono(2-ethylhexyl) phthalate (MEHP), an active metabolite, in mammals. In the present study, the hydrolysis of DEHP by the liver and intestinal microsomes of humans, monkeys, dogs, rats, and mice was examined. The kinetics of liver microsomes fit the Michaelis-Menten model for humans, monkeys, and rats, and the Hill model for dogs and mice. K or S values were similar among species, whereas V exhibited species diffe...

Applying art to scientific research: reasons for using an original method.

Art, by virtue of its symbolic power, may function as a cognitive instrument and even as an aid in the scientific research process, especially in the phase of hypothesis generation and data analysis given its ability to induce creative and intuitive thinking. In this article, we propose a method to put such concept into practice based on the exposure of scientists to collective artistic activities in protected settings, a methodology developed from the experiences described by renowned artists and scientist...

Rabbits and men: relating their ages.

Rabbit, a member of the Lagomorpha order, is the closest phylogenetic relative to humans, next to primates. It possesses greater acceptability as a laboratory mammal than primates in terms of husbandry, breeding ease, cost effectiveness, and legal ethical conveniences. Moreover, as a laboratory animal, the rabbit also owns its advantages over mice or rats, in terms of phylogenetic resemblance to human, size, blood volume, responsiveness, and other congruences enabling them to better imitate human physiologi...

What Happens with the Circuit in Alzheimer's Disease in Mice and Humans?

A major mystery of many types of neurological and psychiatric disorders, such as Alzheimer's disease (AD), remains the underlying, disease-specific neuronal damage. Because of the strong interconnectivity of neurons in the brain, neuronal dysfunction necessarily disrupts neuronal circuits. In this article, we review evidence for the disruption of large-scale networks from imaging studies of humans and relate it to studies of cellular dysfunction in mouse models of AD. The emerging picture is that some forms...

Pharmacodynamics of regulatory T cells in mice and humans treated with low-dose interleukin-2.

We have developed and validated a mathematical model depicting and predicting the effect of low-dose interleukin-2 on Treg expansion in mice and humans. This model should help in the design of optimal therapeutic schemes for the long-term treatment of various chronic autoimmune, inflammatory or allergic diseases.

Monopoiesis in humans and mice.

Monocytes are a widely conserved cell population in vertebrates with important roles in both inflammation and homeostasis. Under both settings, monocytes continuously arise from hematopoietic progenitors in the bone marrow and, on demand, migrate into tissues through the bloodstream. Monocytes are classified into three subsets - classical, intermediate and non-classical - based on their cell-surface expression of CD14 and CD16 in humans and Ly6C, CX3CR1 and CCR2 in mice. In tissues, monocytes differentiate ...

Navigating the path to a biomedical science career.

The number of biomedical PhD scientists undergoing training and graduating far exceeds the number of academic faculty positions and academic research jobs. This trend compels biomedical PhD scientists to increasingly seek career paths outside of academia. Prior studies have used quantitative methodology to determine trends and outcomes of single factors contributing to this shift, but there is a literature gap in studies considering multiple factors and in qualitative work focusing on biomedical PhD scienti...

Scientists on the Spot: Carol Ann Remme on her research and career.

Climate change and skin disease.

Despite commanding essentially universal scientific consensus, climate change remains a divisive and poorly understood topic in the United States. Familiarity with this subject is not just for climate scientists. The impact of climate change on human morbidity and mortality may be considerable; thus, physicians also should be knowledgeable in this realm. Climate change science can seem opaque and inferential, creating fertile ground for political polemics and undoubtedly contributing to confusion among the ...

Contemporary global perspectives of medical students on research during undergraduate medical education: a systematic literature review.

The need for increased expertise in evidence-based medicine and concerns about the decreasing numbers of physician-scientists have underscored the need for promoting and encouraging research in medical education. The critical shortage of physician-scientists has assumed a dimension demanding a coordinated global response. This systematic review examined the perceptions of medical students regarding research during undergraduate medical school from a global perspective.

Researchers' attitudes to the 3Rs-An upturned hierarchy?

Animal use in biomedical research is generally justified by its potential benefits to the health of humans, or other animals, or the environment. However, ethical acceptability also requires scientists to limit harm to animals in their research. Training in laboratory animal science (LAS) helps scientists to do this by promoting best practice and the 3Rs. This study evaluated scientists' awareness and application of the 3Rs, and their approach to other ethical issues in animal research. It was based on an o...

Sex bias in preclinical research and an exploration of how to change the status quo.

There has been a revolution within clinical trials to include females in the research pipeline. However, there has been limited change in the preclinical arena; yet the research here lays the ground work for the subsequent clinical trials. Sex bias has been highlighted as one of the contributing factors to the poor translation and replicability issues undermining preclinical research. There have been multiple calls for action and the funders of biomedical research are actively pushing the inclusion of sex a...

Ultra-rapid near universal TB drug regimen identified via parabolic response surface platform cures mice of both conventional and high susceptibility.

As current treatment of tuberculosis is burdensomely long, provoking non-adherence and drug resistance, effective short-course treatments are needed. Using the output-driven parabolic response surface (PRS) platform, we have identified drug regimens that treat tuberculosis more rapidly in mice than the current Standard Regimen used in humans. We show that PRS Regimen III, comprising clofazimine, SQ109, bedaquiline and pyrazinamide, rapidly sterilizes the lung both in conventionally studied BALB/c mice and i...

Hypercholesterolemia induces T cell expansion in humanized immune mice.

Emerging data suggest that hypercholesterolemia has stimulatory effects on adaptive immunity and that these effects can promote atherosclerosis and perhaps other inflammatory diseases. However, research in this area has relied primarily on inbred strains of mice whose adaptive immune system can differ substantially from that of humans. Moreover, the genetically induced hypercholesterolemia in these models typically results in plasma cholesterol levels that are much higher than those in most humans. To overc...

The clinician-scientist track: an approach addressing Australia's need for a pathway to train its future clinical academic workforce.

Clinician-scientist training represents the epitome of preparation for biomedical scientific discovery. The significance of, and need for, clinician-scientists is universally recognised as essential to progress medical research across what is regarded as the 'translational gap'. Despite a rich history of cutting-edge biomedical research, Australia has no infrastructure or career pathway for training clinician-scientists.

Reduced type III neuregulin 1 expression does not modulate the behavioural sensitivity of mice to acute Δ-tetrahydrocannabinol (D-THC).

Mice with a mutation in the transmembrane domain of the schizophrenia risk gene, neuregulin 1 (Nrg1 TM HET), are more susceptible to the neuro-behavioural effects of Δ-tetrahydrocannabinol (D-THC), the principal psychoactive component in cannabis. However, NRG1 is transcriptionally complex with over 30 different isoforms, most of which carry a transmembrane domain, raising the question which NRG1 isoform(s) may contribute to this phenotype. Type III NRG1/Nrg1 is the most brain abundant isoform and brain st...
