Predicting Body Weight from Birth to Old Age in Giant Pandas Using Machine Learning.

The giant panda () is one of the animals with the largest body weight differences between its birth and adult stages, where the newborn cub is 0.1% the size of its mother. The rapid growth of panda cubs has been reported previously, but little is known about the growth pattern of their entire lifetime.

Cefotaxime Exposure-Caused Oxidative Stress, Intestinal Damage and Gut Microbial Disruption in .

Cefotaxime (CTX) is an easily detectable antibiotic pollutant in the water environment, but little is known about its toxic effects on aquatic invertebrates, especially on the intestine. Here, we determined the oxidative stress conditions of under CTX exposure with five concentrations (0, 0.001, 0.

Multifunctional metamaterial device based on VO and the equivalent diode.

This paper proposes a switchable multifunctional metamaterial device operating in the terahertz (THz) band. The device is loaded with an equivalent diode and utilizes vanadium dioxide ( ). The middle layer of the whole device, a metal layer, divides the device into the I side and the II side.

Sequence analysis of the ATP synthase of subunits ( and ) genes of mitochondrial DNA genome from .

To explore the effects of the mutations of and genes on energy metabolism and genetic structure, we sequenced the and genes of . Our results showed that is a conserved gene and gene is positively selected during the evolution of the giant panda population with a low genetic diversity. Population expansion was observed in the giant panda group.

Complete mitochondrial genome sequence of (Aves, Gallifoemes, phasianidae) and its phylogenetic analysis.

one of the most important and be cherished uncultivated animals, although, origins of the most remain unknown. Therefore, the complete mitochondrial genome of the (also named seven-colours , one of the oldest wild birds in China known for their preciousness) was obtained for the first time, the mitogenome is 166,786 bp in length, and it harbours 2rRNA genes, 13 protein-coding genes, 22tRNA genes, and a D-loop region. According to the phylogenetic tree, we can assume that and are within the same lineage, and is a different group with Red Jungle.

Analysis of the cytochrome c oxidase subunit 1 (COX1) gene reveals the unique evolution of the giant panda.

As the rate-limiting enzyme of the mitochondrial respiratory chain, cytochrome c oxidase (COX) plays a crucial role in biological metabolism. "Living fossil" giant panda (Ailuropoda melanoleuca) is well-known for its special bamboo diet. In an effort to explore functional variation of COX1 in the energy metabolism behind giant panda's low-energy bamboo diet, we looked at genetic variation of COX1 gene in giant panda, and tested for its selection effect.

Anti-methicillin-resistant Staphylococcus aureus assay of azalomycin F5a and its derivatives.

Aim: To discover anti-methicillin-resistant Staphylococcus aureus (anti-MRSA) microbial natural products or their derivatives.

Method: Azalomycin F5a (1) was prepared through fermentation of Streptomyces hygroscopicus var. azalomyceticus, and its derivatives were synthesized through hydrocarbylation in hydrocarbyl alcoholic-AcOH (4 : 1) and subsequent demalonylation with 2 mol·L(-1) KOH in MeOH-H2O (7 : 3).

Hemolymph juvenile hormone titers in worker honey bees under normal and preswarming conditions.

Swarming is an important mechanism by which honey bee, Apis mellifera L., colonies reproduce, yet very little is known about the physiological changes in workers that are preparing to swarm. In this study, we determined the endocrine status of worker honey bees in preswarming colonies and in normal (nonswarming) colonies.
