Hrdlička’s Aleutian Population‐Replacement Hypothesis

Current Anthropology, 2006
In a 1945 monograph, Hrdlika argued that, at 1,000 BP, PaleoAleut people on Umnak Island were replaced by NeoAleut groups moving west along the island chain. His argument was based on cranial measurements of skeletal remains from Chaluka Midden and mummified remains from Kagamil and Ship Rock burial caves.

Awareness about total knee replacement among Saudi population

Journal of Family Medicine and Primary Care, 2022
Introduction: The purpose of this study is to identify the knowledge of the general population about knee osteoarthritis and its surgical interventions in the management of knee osteoarthritis. Knee osteoarthritis is a prevalent disease.

Inverse Medea as a Novel Gene Drive System for Local Population Replacement: A Theoretical Analysis [PDF]

Journal of Heredity, 2011
One strategy to control mosquito-borne diseases, such as malaria and dengue fever, on a regional scale is to use gene drive systems to spread disease-refractory genes into wild mosquito populations.

Is half the world's population really below 'replacement-rate'?

PLoS ONE, 2019
A perennial activity of demographers is to estimate the percentage of the world's population which is above or below the 'replacement rate of fertility' [RRF].

Replacement of Leishmania (Leishmania) infantum Populations in an Endemic Focus of Visceral Leishmaniasis in Brazil

Frontiers in Cellular and Infection Microbiology, 2022
Visceral leishmaniasis is an important global health problem with an estimated of 50,000 to 90,000 new cases per year. VL is the most serious form of leishmaniasis as it can be fatal in 95% of the cases if it remains untreated. VL is a particularly acute

Threshold dynamics of a stochastic mathematical model for Wolbachia infections

Journal of Biological Dynamics, 2023
A stochastic mathematical model is proposed to study how environmental heterogeneity and the augmentation of mosquitoes with [Formula: see text] bacteria affect the outcomes of dengue disease. The existence and uniqueness of the positive solutions of the

Population replacement gene drive characteristics for malaria elimination in a range of seasonal transmission settings: a modelling study

bioRxiv, 2021
Background Gene drives are a genetic engineering method where a suite of genes is inherited at higher than Mendelian rates and has been proposed as a promising new vector control strategy to reinvigorate the fight against malaria in sub-Saharan Africa ...

Monitoring Needs for Gene Drive Mosquito Projects: Lessons From Vector Control Field Trials and Invasive Species

Frontiers in Genetics, 2022
As gene drive mosquito projects advance from contained laboratory testing to semi-field testing and small-scale field trials, there is a need to assess monitoring requirements to: i) assist with the effective introduction of the gene drive system at ...
