Chickpeas are rich sources of highly nutritious protein and dietary fibre; the health benefits of consuming legumes such as antioxidant activity (AoxA) could be effective for the expansion of their food uses. The technological properties and antioxidant potential of five pigmented chickpea cultivars were evaluated. Protein content of the grains varied from 24.9 to 27.4 g/100 g sample (dw). The cooking time (CT) of the whole grains ranged from 90.5 to 218.5 min; the lowest CT corresponded to Black ICC3761 cultivar. The total phenolic content (TPC) and AoxA [oxygen radical absorbance capacity (ORAC) value] varied from 1.23 to 1.51 mg GAE/g sample (dw) and from 5011 to 5756 μmol TE/100 g sample (dw), respectively; Red ICC13124 showed the highest ORAC value. The differences in technological properties and AoxA among cultivars could be used in chickpea breeding programmes. Chickpea cultivars could contribute significantly to the management and/or prevention of degenerative diseases associated with free radical damage.

Maya civilization developed in Mesoamerica and encompassed the Yucatan Peninsula, Guatemala, Belize, part of the Mexican states of Tabasco and Chiapas, and the western parts of Honduras and El Salvador. This civilization persisted approximately 3,000 years and was one of the most advanced of its time, possessing the only known full writing system at the time, as well as art, sophisticated architecture, and mathematical and astronomical systems. This civilization reached the apex of its power and influence during the Preclassic period, from 2000 BCE to 250 CE. Genetic variation in the pre-Hispanic Mayas from archaeological sites in the Mexican states of Yucatan, Chiapas, Quintana Roo, and Tabasco and their relationship with the contemporary communities in these regions have not been previously studied. Consequently, the principal aim of this study was to determine mitochondrial DNA (mtDNA) variation in the pre-Hispanic Maya population and to assess the relationship of these individuals with contemporary Mesoamerican Maya and populations from Asia, Beringia, and North, Central, and South America. Our results revealed interactions and gene flow between populations in the different archaeological sites assessed in this study. The mtDNA haplogroup frequency in the pre-Hispanic Maya population (60.53%, 34.21%, and 5.26% for haplogroups A, C, and D, respectively) was similar to that of most Mexican and Guatemalan Maya populations, with haplogroup A exhibiting the highest frequency. Haplogroup B most likely arrived independently and mixed with populations carrying haplogroups A and C based on its absence in the pre-Hispanic Mexican Maya populations and low frequencies in most Mexican and Guatemalan Maya populations, although this also may be due to drift. Maya and Ciboneys sharing haplotype H10 belonged to haplogroup C1 and haplotype H4 of haplogroup D, suggesting shared regional haplotypes. This may indicate a shared genetic ancestry, suggesting more regional interaction between populations in the circum-Caribbean region than previously demonstrated. Haplotype sharing between the pre-Hispanic Maya and the indigenous populations from Asia, the Aleutian Islands, and North, Maternal Lineage in Pre-Hispanic and Contemporary Mayas ■ 137Central, and South America provides evidence for gene flow from the ancestral Amerindian population of the pre-Hispanic Maya to Central and South America.

The acceptability properties, total phenolic content, and antioxidant potential of four (red, green, brown, cream) desi chickpea (<i>Cicer arietinum</i> L.) cultivars from the World Germplasm Bank were evaluated. Protein content of the grains varied from 20.12% to 28.85% (dw), highest for Cream ICC3421. The water absorption capacity (WAC) and cooking time (CT) of the whole grains ranged from 97.7 to 117.5 g water/100 g seeds (ww) and from 109.5 to 193.5 min, respectively; the highest WAC and lowest CT corresponded to Cream ICC3421 cultivar. The total phenolic content (TPC) and total hydrophilic antioxidant activity (AoxA) [oxygen radical absorbance capacity (ORAC) value] of desi chickpea cultivars varied from 746 to 1.286 µg gallic acid equivalents (GAE)/g sample (dw) and from 43.9 to 53.9 µmol Trolox equivalents (TE)/g sample (dw); Brown ICC3512 showed the highest ORAC value. Chickpea cultivars could contribute significantly to the management and/or prevention of degenerative diseases associated with free radical damage

The Maya civilization developed in Mesoamerica persisted approximately 3,000 years and was one of the most advanced of its time. Mayas had the only known full writing system, as well as highly developed mathematical and astronomical systems. They also developed sophisticated architecture and arts. The Maya area of settlement ranged from the Yucatan Peninsula through Guatemala, Belize, and part of the Mexican states of Tabasco and Chiapas, as well as parts of Honduras and El Salvador. The Maya civilization reached its peak of power and influence in the Preclassic period, from 2000 BCE to 250 CE. Despite the profound impact of the Mayan civilization on Mesoamerica and neighboring populations, studies of genetic variation of ancient Maya populations in pre-European times are scarce. Therefore, this work examines evidence in ancient DNA from archaeological sites in the states of Yucatan, Chiapas, Quintana Roo, and Tabasco. We report data analysis from sequences of the mtDNA hypervariable region I (HV1) from bone remains found in excavations of archaeological sites of the Maya region and their relationship with ancient and contemporary communities in this region, including Central and South America, as well as with Asia and Beringia. We discuss the results in the light of the influence of climate change in the area and relate them to evidence from language change. Gene flow within the Maya area occurred with a directional flow to South America in the Preclassic and Classic eras of the Mesoamerican chronology. This is supported by historical documentation, that has shown that the ancestors of the Maya civilization entered the Yucatan Peninsula after the first movement of people from Northern Asia into the Americas, with later migrations of the Maya ancestors to Mesoamerica, through Central America and the Caribbean, and toward the northern portions of South America.
