In the 14th century AD, medieval Europe was severely affected by the Great European Famine as well as repeated bouts of disease, including the Black Death, causing major demographic shifts. This high volatility led to increased mobility and migration due to new labor and economic opportunities, as evidenced by documentary and stable isotope data. This study uses ancient DNA (aDNA) isolated from skeletal remains to examine whether evidence for large-scale population movement can be gleaned from the complete mitochondrial genomes of 264 medieval individuals from England (London) and Denmark.

Understanding the resistance and resilience of foundation plant species to climate change is a critical issue because the loss of these species would fundamentally reshape communities and ecosystem pr...
Asiatic black bears (Ursus thibetanus) have a widespread distribution in mountain landscapes, and are considered vulnerable globally, but are low-priority species for conservation in Nepal. Habitat fr...
The ever-increasing human-mediated wildlife reshuffling is raising concern for the conservation of biodiversity. The loss of biological distinctiveness among regions lessens the genetic diversity and ...
When a black hole forms from collapse in a holographic theory, the information in the black hole interior remains encoded in the boundary. We prove that the area of the black hole's apparent horizon i...
Porcine circovirus type 2 (PCV-2), is linked to PCV-2 associated disease, which has caused considerable economic loss in the swine industry. Here, we report the genetic diversity of PCV-2 in China. A ...
The purpose of the study is to test an experimental method, a text-messaging app called B-RESILIENT, for improving participants' mood. B-RESILIENT is a text messaging app adaptation of a R...
This is a prospective study that will examine psychosocial improvements among CF adolescents and caregivers going through the Stress Management and Resiliency Training - Relaxation Respons...
Sudden cardiac arrest (SCA) is a sudden, unexpected loss of heart function. It is a leading cause of death, and more than 400,000 people in the United States die each year as a result of S...
Black men constitute the demographic group with the greatest burden of premature death and disability from hypertension (HTN) in the United States. But while the disproportionately high ra...
This study is to evaluate the effects of the SMART-3RP (Stress Management and Resiliency Training Relaxation Response Resiliency Program) on physician and academic faculty well-being, perc...
The phenomenon of immense variability characteristic of ANTIBODIES. It enables the IMMUNE SYSTEM to react specifically against the essentially unlimited kinds of ANTIGENS it encounters. Antibody diversity is accounted for by three main theories: (1) the Germ Line Theory, which holds that each antibody-producing cell has genes coding for all possible antibody specificities, but expresses only the one stimulated by antigen; (2) the Somatic Mutation Theory, which holds that antibody-producing cells contain only a few genes, which produce antibody diversity by mutation; and (3) the Gene Rearrangement Theory, which holds that antibody diversity is generated by the rearrangement of IMMUNOGLOBULIN VARIABLE REGION gene segments during the differentiation of the ANTIBODY-PRODUCING CELLS.
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
A conserved protein interaction domain of the death domain superfamily that is structurally similar to the DEATH EFFECTOR DOMAIN and CASPASE RECRUITMENT DOMAIN. Death domains bind each other to form oligomers and occur on DEATH DOMAIN RECEPTORS, where they are required for APOPTOSIS signaling and non-apoptotic functions.
Production of new arrangements of DNA by various mechanisms such as assortment and segregation, CROSSING OVER; GENE CONVERSION; GENETIC TRANSFORMATION; GENETIC CONJUGATION; GENETIC TRANSDUCTION; or mixed infection of viruses.
The death of a FETUS of GESTATIONAL AGE 28 weeks or more, or the death of a live-born INFANT less than 28 days of age.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
