Genetic differences between Chibcha and Non-Chibcha speaking tribes based on mitochondrial DNA (mtDNA) haplogroups from 21 Amerindian tribes from Colombia [PDF]

Genetics and Molecular Biology, 2013
We analyzed the frequency of four mitochondrial DNA haplogroups in 424 individuals from 21 Colombian Amerindian tribes. Our results showed a high degree of mtDNA diversity and genetic heterogeneity.

Leisure time television watching, computer use and risks of breast, colorectal and prostate cancer: A Mendelian randomisation analysis. [PDF]

Cancer Med
Abstract Background Sedentary behaviours have been associated with increased risks of some common cancers in epidemiological studies; however, it is unclear if these associations are causal. Methods We used univariable and multivariable two‐sample Mendelian randomisation (MR) to examine potential causal relationships between sedentary behaviours and ...

Recurrent Coding Sequence Variation Explains Only A Small Fraction of the Genetic Architecture of Colorectal Cancer. [PDF]

Sci Rep, 2015
Whilst common genetic variation in many non-coding genomic regulatory regions are known to impart risk of colorectal cancer (CRC), much of the heritability of CRC remains unexplained.

Genetic overlap between endometriosis and endometrial cancer: evidence from cross-disease genetic correlation and GWAS meta-analyses. [PDF]

Cancer Med, 2018
Investigating shared biological etiology between endometriosis and endometrial cancer using genomewide genetic data has revealed moderate, significant genetic correlation between them and highlighted 13 genetic loci associated at P ≤ 10−5 with both diseases. One of these SNPs, associated at a genomewide significant level (P = 4.9 × 10−8, OR = 1.11, 95%

Clasificación social entre los habitantes de la lengua Chibcha

Maguaré, 1998
Los principios organizativos del "matrimonio de primos cruzados" parecieron haber orientado, desde tiempos prehispánicos, las relaciones sociales de muchas de las sociedades nativas del país.

Language, Science and Globalization in the Eighteenth Century**

Berichte zur Wissenschaftsgeschichte, Volume 46, Issue 1, Page 38-53, March 2023., 2023
Abstract Asia, America, and Europe have been intellectually intertwined for centuries. Several studies have been published revealing European scholars’ interest in the “exotic” languages of Asia and America, as well as in ethnographic and anthropological aspects.

Phylogenetic revision of Dennstaedtioideae (Dennstaedtiaceae: Polypodiales) with description of Mucura, gen. nov.

TAXON, Volume 72, Issue 1, Page 20-46, February 2023., 2023
Abstract We undertook a molecular phylogenetic revision of hayscented ferns (Dennstaedtiaceae: Dennstaedtioideae) using four plastid markers. Our sampling represents ca. 40% of the extant diversity and includes the type species for each of the relevant segregate genera.

Language classification, language contact and Andean prehistory: The North

Language and Linguistics Compass, Volume 15, Issue 5, May 2021., 2021
Abstract The northern half of the Andes—from Venezuela to Northern Peru—has seen dramatic losses of language diversity since the 16th century. Even so, the region's linguistic fabric is complex and multifaceted, and the impression of relatively low levels of diversity vis‐à‐vis Amazonia is to a perhaps considerable extent the result of different post ...

Circulating adipokine concentrations and risk of five obesity‐related cancers: A Mendelian randomization study

International Journal of Cancer, Volume 148, Issue 7, Page 1625-1636, 1 April 2021., 2021
Abstract Obesity is considered a chronic inflammatory state characterized by continued secretion of adipokines and cytokines. Experimental and epidemiological evidence indicates that circulating adipokines may be associated with the development of obesity‐related cancers, but it is unclear if these associations are causal or confounded.
