[Research progress on quantitative evaluation methods of urban ecological carrying capacity].

Quantitative evaluation of urban ecological carrying capacity is a critical foundation for measuring urban sustainable development in the new era. This review would enrich the concept and connotation of urban ecological carrying capacity by sorting out its components and characteristics. We categorized the methods for quantifying urban ecological carrying capacity into static evaluation methods, including ecological footprint method, comprehensive evaluation method, state space method, net primary productivity method, and carbon-oxygen balance method, as well as dynamic simulation prediction methods, including system dynamics models, BP neural network prediction models, and grey prediction models.

Age-adjusted Charlson comorbidity index is associated with the risk of osteoporosis in older fall-prone men: a retrospective cohort study.

Phylogenetic position and morphological polymorphism of the chafer, (Coleoptera: Scarabaeidae: Cetoniinae) from Taiwan.

Three mitochondrial genomes of the cetoniine beetle, (Kano, 1931) were assembled via next-generation sequencing. The newly sequenced mitogenomes all have 37 genes, showing standard gene order and annotation as the other insects. To examine their phylogenetic positions and relationships between their elytral color (red-spot and melanistic forms) and sequence variation, a total of 118 public mitogenomes of Scarabaeidae were used to infer a maximum-likelihood (ML) tree.

Astragalus Polysaccharides Reduce High-glucose-induced Rat Aortic Endothelial Cell Senescence and Inflammasome Activation by Modulating the Mitochondrial Na/Ca Exchanger.

Vascular endothelial cells play a vital role in atherosclerotic changes and the progression of cardiovascular disease in older adults. Previous studies have indicated that Astragalus polysaccharides (APS), a main active component of the traditional Chinese medicine Astragalus, protect mitochondria and exert an antiaging effect in the mouse liver and brain. However, the effect of APS on rat aortic endothelial cell (RAEC) senescence and its underlying mechanism have not been investigated.

Effects of a prolonged diet regimen on autophagic function in rat islets with aging.

The prevalence of type 2 diabetes increases with age-associated increased susceptibility of islet β-cells and altered dietary patterns, in part because of insufficient compensation of β-cell functional mass in the face of increasing insulin resistance. However, the underlying mechanisms have not been fully elucidated. In the present study, we investigated the effects of a long-term calorie-restricted (CR) or high-fat (HF) diet compared to a normal ad libitum diet on β-cell structure-function relationships and autophagy in the islets of 3- and 24-month-old Fischer 344 rats.

Two mitochondrial genomes of Taiwanese rhinoceros beetles, and (Coleoptera: Scarabaeidae).

Two mitochondrial genomes of the dynastine beetles, (Linnaeus, 1758) and (Faldermann, 1835), were assembled high-throughput sequencing (HTS). Each of the mitogenomes has 37 genes, showing standard gene order and annotation as the other insects, except for the transfer genes, presenting tQ-tI-tM order. To examine their phylogenetic positions, 118 public mitogenomes of Scarabaeidae were used to infer a ML tree.

[Relationship between urban atmospheric environment and surrounding two-dimensional and three-dimensional landscape pattern in China.].

Atmospheric environment in urban built-up area is severely influenced by the surrounding landscape pattern. Understanding the relationship between air pollution and surrounding landscape pattern at small scale has great significance for mitigating air pollution from the perspective of urban construction. The annual average concentrations of NO, SO, PM and PM from 266 air pollution monitoring stations in 30 provincial capitals of China in 2017 were chosen as dependent variables.

Identification, expression, and artificial selection of silkworm epigenetic modification enzymes.

Background: Understanding the genetic basis of phenotype variations during domestication and breeding is of great interest. Epigenetics and epigenetic modification enzymes (EMEs) may play a role in phenotypic variations; however, no comprehensive study has been performed to date. Domesticated silkworm (Bombyx mori) may be utilized as a model in determining how EMEs influence domestication traits.

Molecular basis of the silkworm mutant re causing red egg color and embryonic death.

The coloration and hatchability of insect eggs can affect individual and population survival. However, few genetic loci have been documented to affect both traits, and the genes involved in regulating these two traits are unclear. The silkworm recessive mutant re shows both red egg color and embryo mortality.

Estimation of sex based on patella measurements in a contemporary Chinese population using multidetector computed tomography: An automatic measurement method.

Sex estimation is an important part of creating a biological profile, and ultimately assisting in creating a presumptive identification of unidentified skeletal remains. However, manual methods of anthropometric are time-consuming and prone to observer variability. The present study is an attempt to estimation of sex from automatic measurement of patella by multidetector computed tomography (MDCT) in a contemporary Chinese population.

Natural products that target macrophages in treating non-alcoholic steatohepatitis.

Nonalcoholic steatohepatitis (NASH) is the progressive subtype of non-alcoholic fatty liver disease and potentiates risks for both hepatic and metabolic diseases. Although the pathophysiology of NASH is not completely understood, recent studies have revealed that macrophage activation is a major contributing factor for the disease progression. Macrophages integrate the immune response and metabolic process and have become promising targets for NASH therapy.

Downregulation of MiR-218 can alleviate high-glucose-induced renal proximal tubule injury by targeting GPRC5A.

The purpose of this study was to explore the functional implication of microRNA-218 (miR-218) in diabetic nephropathy (DN) through high-glucose-stimulated renal proximal tubule impairment. Biological function experiments showed that miR-218 and inflammatory factors TNF-α and IL-1β were highly expressed in renal proximal tubule under high-glucose conditions. Inhibiting miR-218 alleviated renal tubular cell injury, which was represented by miR-218 inhibitor facilitating renal tubular cell vitality whilst reducing its apoptosis and levels of inflammation factors.

[Research progress on three-dimensional pattern in landscape ecology].

The close interactions between abiotic and biotic components create a variety of three-dimensional (3-D) landscape patterns. Landscape ecology, as a discipline of studying patterns and ecological processes, has made rapid progress in the exploration of 3-D space with the improvement of data acquirement ability, such as lidar technology. The real surface landscape can be described considering 3-D data, which improves the consistency between landscape indices and ecological process, and has overcome the shortage of ecological meanings of traditional researches.

Genome-wide identification and expression profiling of the C2H2-type zinc finger protein genes in the silkworm .

Cys2-His2 zinc finger (C2H2-ZF) proteins comprise the largest class of putative eukaryotic transcription factors. The zinc finger motif array is highly divergent, indicating that most proteins will have distinctive binding sites and perform different functions. However, the binding sites and functions of the majority of C2H2-ZF proteins remain unknown.
