Dataset Information

Complete mitochondrial genome sequence of Glyptothorax annandalei in the Yarlung Zangbo River, Tibet.

ABSTRACT: Glyptothorax annandalei belongs to the family of Sisoridae, Glyptothorax. It is distributed in the Yarlung Zangbo River of southwestern China. In this study, we first published the complete mitochondrial genome sequence of Glyptothorax annandalei, which was 16,541 bp in length. This genome consists of two rRNA genes, 22 tRNA genes, 13 protein-coding genes (PCGs), and a putative control region. The overall base composition was for A(31.25%,) for T(25.67%), for C(27.66%), for G(15.42%). The PCGs start with a traditional ATG except for COX1 start with GTG, respectively, and end with stop codon TAA, TAG, or a single T base. All tRNA have the typical clover-leaf structure. The phylogenetic tree of the whole mitogenome sequence is constructed by maximum likelihood (ML) method and the phylogenetic relationship among the family Sisoridae is further analyzed. We expect to provide the theoretical basis for the further study of the phylogenetic relationship, taxonomic status, conservation and management of genetic resources of Sisoridae catfishes.

Project description:BackgroundDietary intake and nutritional assessing data from a representative sample of adult population living in an agricultural zone on Tibet Plateau are still lacking nowadays. This study aimed to assess the daily dietary intakes and respective food sources in 552 local residents (≥ 18 years old, 277 men and 275 women) living in 14 agricultural counties along the Yarlung Zangbo River on Tibet Plateau.MethodsFood consumption data were collected using a validated cultural-specific food frequency questionnaire that contained all local Tibetan foods and analyzed with three fixed factors: gender, age, and region. Nutrient intakes were calculated using Chinese food composition tables. Nutritional gaps and the percentages of participants who had inadequate and excessive nutrient intakes were calculated by estimated average requirement (EAR) cut-point methods.ResultsCompared with the dietary reference intakes, 68.4% of nutrient intakes were inadequate. Fiber, Ca, I, Zn, Se, and vitamin (Va, Vc, and folic acid) intakes appeared to be particularly deficient. The dietary energy intake was 7838.8 ± 537.1 KJ/d, with 78 and 84% of EAR values for men and women, respectively. The dietary intakes of most nutrients were below the estimated energy requirement/EAR or adequate intake values, while more than 70% of the participants had excessive intake of carbohydrate, especially the elderly (aged ≥ 51 years). The nutritional gap of Cu was more than 300%. Almost 100% of the participants was vulnerable to fiber, Se, and Va shortfalls due to the deficiency in sole food sources. The top five food sources of Se intake were highland barley (34.2%), meat (13%), rice (12.4%), eggs (12.2%), and cultural-specific beverages (7.8%). Eggs (42.1%), tubers (62.2%), vegetables (66.4%), and highland barley (49.7%) were the first contributors of Va, Ve, Vc, and folic acid, respectively.ConclusionThe dietary intake of a large sample of Tibetan adult population living in agricultural counties of Tibetan Autonomous Region is alarmingly insufficient. Gender inequality is common, and regional difference is widespread due to rapid urbanization. Young Tibetan adults aged 18-30 years are particularly vulnerable to micronutrient shortfalls and currently facing the risk of nutrition-insecurity-related dietary inadequacy. The respondents who belong to the elderly category (≥51 years of age) are facing the risk of "double burden of malnutrition" characterized by the coexistence of undernutrition, including micronutrient deficiencies and overweight or obesity.
