Article Synopsis
  • Archaeal group II chaperonins, or heat shock proteins (HSPs), are crucial for protein folding and protection during thermal stress in Sulfolobales, especially when faced with thermal shock.
  • HSPs maintain structural integrity at neutral pH and varying temperatures but show significant changes at ultra-low pH (pH 2), with HSPα and HSPβ being more thermostable than HSPβ-coh.
  • Molecular dynamics simulations support lab findings, revealing stability differences among HSP subtypes and highlighting limitations in acid tolerance despite their thermal resilience.

Hippocampal dentate gyral dysplasia is well-described in temporal lobe epilepsy and may be a risk factor for sudden, unexpected death in several populations: infants (sudden infant death syndrome [SIDS], sudden unexpected infant death [SUID]), toddlers (sudden unexpected death of a child [SUDC]), and epileptics (sudden unexpected death in epilepsy [SUDEP]). We examined reports and histopathological slides from autopsies performed at our institution from 2008 through 2016 to determine whether the presence or absence of any of the described forms of such dysplasias (duplications, hyperconvolutions, and granule cell dispersion, including bilamination), correlated with the causes of death. From well over 4000 autopsies, we identified 949 autopsies with a neuropathology examination by a neuropathologist.

Background: Organisms frequently experience environmental stresses that occur in predictable patterns and combinations. For wild Saccharomyces cerevisiae yeast growing in natural environments, cells may experience high osmotic stress when they first enter broken fruit, followed by high ethanol levels during fermentation, and then finally high levels of oxidative stress resulting from respiration of ethanol. Yeast have adapted to these patterns by evolving sophisticated "cross protection" mechanisms, where mild 'primary' doses of one stress can enhance tolerance to severe doses of a different 'secondary' stress.

We conducted a randomized controlled trial to determine whether an after-school program paired with a cash transfer (a conditional cash transfer) or a cash transfer alone (an unconditional cash transfer) can help improve health and economic outcomes for young men between the ages of 14 and 17 whose parents have low incomes and who live in neighborhoods with high crime rates. We find that receiving the cash transfer alone was associated with an increase in healthy behaviors (one of our primary outcome composite measures) and that the cash transfer paired with after-school programming was associated with an improvement in the financial health of participants (one of our secondary outcome composite measures). We find no differences in spending on alcohol, marijuana, cigarettes, or other drugs between either the treatment group and the control group.

Article Synopsis
  • Childhood diseases represent significant public health challenges linked to environmental exposures, collectively known as the exposome, impacting various health outcomes in children.
  • A comprehensive analysis reviewed studies on 88 environmental factors, finding that 44 factor-outcome pairs had a "very likely" level of evidence for negative health impacts, while many others showed either limited or no evidence.
  • The most concerning environmental factors included chemicals like HCB, PCBs, and PFOA, which were associated with multiple adverse health outcomes, emphasizing the need for ongoing research and policy action to address these risks.

Nonaccidental head injuries are significant causes of morbidity and mortality among young children. Despite broad agreement among medical experts, controversies remain over diagnostic criteria, including from autopsies, because of opinions expressed by a small group of expert witnesses who testify for defendants in suspected child homicide cases. We reviewed 249 autopsies in children 2 years old and younger from the files of our Medical Examiner office in the University of Missouri School of Medicine done between January 1, 2008 and December, 31, 2016.

B-cell maturation antigen (BCMA) is a prominent tumor-associated target for chimeric antigen receptor (CAR)-T cell therapy in multiple myeloma (MM). Here, we describe the case of a patient with MM who was enrolled in the CARTITUDE-1 trial ( NCT03548207 ) and who developed a progressive movement disorder with features of parkinsonism approximately 3 months after ciltacabtagene autoleucel BCMA-targeted CAR-T cell infusion, associated with CAR-T cell persistence in the blood and cerebrospinal fluid, and basal ganglia lymphocytic infiltration. We show BCMA expression on neurons and astrocytes in the patient's basal ganglia.

A challenge in virology is quantifying relative virulence () between two (or more) viruses that exhibit different replication dynamics in a given susceptible host. Host is often used to mathematically characterize virus-host interactions and to quantify the magnitude of detriment to host due to viral infection. Quantifying using canonical parameters, like maximum specific growth rate (), can fail to provide reliable information regarding virulence.

The Spindle-shaped Virus (SSV) system has become a model for studying thermophilic virus biology, including archaeal host-virus interactions and biogeography. Several factors make the SSV system amenable to studying archaeal genetic mechanisms (e.g.

We examine whether zoning can increase health equity and population health by assessing a new zoning ordinance in the City of Baltimore that forced 76 liquor stores in residential areas to relocate, close, or convert to an approved use. To do so, we undertake a baseline assessment of neighborhoods with affected liquor stores, and predict the potential impact of the zoning change by estimating the impact of previous closures and openings of liquor stores on neighborhood crime in Baltimore using a spatial Poisson random trend fixed effects model. We find that affected stores are concentrated in high poverty, majority black neighborhoods with high vacancy rates, and that liquor store closings are associated with a statistically significant reduction in violent crime on the block group in question with no negative spillover affects onto the nearby block groups.

Governments and nonprofits routinely partner to launch place-based initiatives in distressed neighborhoods with the goal of stabilizing real estate markets, reclaiming vacant properties, abating public nuisances, and reducing crime. Public health impacts and outcomes are rarely the major policy drivers in the design and implementation of these neighborhood scale initiatives. In this article, we examine recent Health Impact Assessments in Baltimore, Maryland and Memphis, Tennessee to show how public health concepts, principles, and practices can be infused into existing and new programs and policies, and how public health programs can help to improve population health by addressing the upstream social determinants of health.

Introduction: Drowning deaths present a challenge for forensic pathologists, because the autopsy findings may occur in many nondrowning scenarios. Previous studies have attempted to identify patterns in organ weights that may be specific for drowning. The drowning index (DI) has been defined as the weight ratio of the lungs and pleural effusion fluid to the spleen.

Transient global amnesia (TGA) is characterized by sudden, temporary dysfunction of antegrade and recent retrograde memory without other neurologic deficits. Although there is sometimes a precipitating event, the origin of TGA remains controversial. We encountered a patient who developed recurrent TGA when upright, in whom the symptom promptly and regularly resolved when supine.

The western corn rootworm remains one of the most important pests of corn in the United States despite the use of many pest management tools. Cry3A, the first coleopteran-active Bacillus thuringiensis toxin isolated, has not been useful for control of the corn rootworm pest complex. Modification of Cry3A so that it contained a chymotrypsin/cathepsin G protease recognition site in the loop between alpha-helix 3 and alpha-helix 4 of domain I, however, resulted in consistent activity of the toxin ("mCry3A") against neonate western corn rootworm.

Recently, five novel fluorescent proteins have been isolated from non-bioluminescent species of reef-coral organisms and have been made available through ClonTech. They are AmCyan, AsRed, DsRed, ZsGreen and ZsYellow. These proteins are valuable as reporters for transformation because they do not require a substrate or external co-factor to emit fluorescence and can be tested in vivo without destruction of the tissue under study.

Fabry disease results from deficient alpha-galactosidase A (alpha-Gal A) activity and the pathologic accumulation of the globotriaosylceramide (GL-3) and related glycosphingolipids, primarily in vascular endothelial lysosomes. Treatment is currently palliative, and affected patients generally die in their 40s or 50s. Preclinical studies of recombinant human alpha-Gal A (r-halphaGalA) infusions in knockout mice demonstrated reduction of GL-3 in tissues and plasma, providing rationale for a phase 1/2 clinical trial.

Sleep disorders can be intrinsic, as are insomnia or narcolepsy, or can be accounted for by external factors, such as noise, altitude, drug or alcohol abuse, or shift work. The arousal disorders, common in children, are usually benign and disappear by puberty. Sleep-wake transition disorders such as sleep starts are benign as well, and may occur at any age.

The effects of aging and caloric restriction on mean arterial pressure (MAP), heart rate (HR), and baroreflex sensitivity were determined in young (7-9 months) and old (22-24 months) awake, male Fischer 344 rats which had been either ad libitum fed or calorie restricted (60% of the ad libitum calories). The MAP of young rats was higher than that of old rats. The MAP of old ad libitum fed rats was higher than that of old restricted rats with no effect of diet in young rats.
