The use of height data to measure living standards is now a well-established method in economic history. Moreover, a number of core findings in the literature are widely agreed upon. There are still some populations, places and times, however, for which anthropometric evidence remains thin. One example is 19th century African-Americans in US border-states. This paper introduces a new data set from the Missouri state prison to track the heights of comparable black and white men born between 1820 and 1904. Modern blacks and whites come to comparable terminal statures when brought to maturity under optimal conditions; however, whites were persistently taller than blacks in the Missouri prison sample by two centimetres. Throughout the 19th century, black and white adult statures remained approximately constant, while black youth stature increased during the antebellum period.

G-quadruplex (G4) structure is a nucleic acid secondary structure formed by guanine-rich sequences, playing essential roles in various biological processes such as gene regulation and environmental stress adaptation. Although prokaryotes growing at high temperatures have higher GC contents, the pattern of G4 structure associated with GC content variation in thermal adaptation remains elusive. This study analyzed 681 bacterial genomes to explore the role of G4 structures in thermal adaptation.

Peripartum cardiomyopathy (PPCM) and takotsubo cardiomyopathy (TCM) are cardiac conditions that can occur in the peripartum period. They have distinct characteristics and incidence rates; although rare, both contribute to the second leading cause of all-cause maternal mortality in the state of Missouri. PPCM can lead to heart failure, and TCM can cause acute arrhythmias leading to sudden cardiac death in otherwise healthy individuals.

The neuromuscular junction (NMJ) is the linchpin of nerve-evoked muscle contraction. Broadly, the function of the NMJ is to transduce nerve action potentials into muscle fiber action potentials (MFAPs). Efficient neuromuscular transmission requires both cholinergic signaling, responsible for generation of endplate potentials (EPPs), and excitation, the amplification of the EPP by postsynaptic voltage-gated sodium channels (Nav1.

Background: Intimate partner violence (IPV) poses a significant threat to the well-being of women and girls and is a highly prevalent form of gender-based violence. Evidence regarding the nutritional implications of IPV has focused primarily on intergenerational relationships with child nutrition and growth. There remains a knowledge gap regarding the association with women's own dietary intake.
