In the top four subplots, 20% randomly selected genes have been artificially up-regulated by 2.5-fold in Array Q, R, S and T. The differentiated genes are marked red, and undifferentiated genes are marked black. The trimming fractions in the subplots are: A, 50%; B, 30%; C, 20%; D, 10%.

Table_1_Effects of whole maize high-grain diet feeding on colonic fermentation and bacterial community in weaned lambs.DOCX
High-grain diet is commonly used in intensive production to boost yield in short term, which may cause adverse effects such as rumen and colonic acidosis in ruminants. Maize is one of the key components of high-grain diet, and different processing methods of maize affect the digestive absorption and gastrointestinal development of ruminants. To investigate the effects of maize form in high-grain diets on colonic fermentation and bacterial community of weaned lambs, twenty-two 2.5-month-old healthy Hu lambs were fed separately a maize meal low-grain diet (19.2% grain; CON), a maize meal high-grain diet (50.4% grain; CM), and a whole maize high-grain diet (50.4% grain; CG). After 7 weeks of feeding, the total volatile fatty acid concentration (P = 0.035) were significantly higher in lambs from CM than that from CON. The sequencing results of colonic content microbial composition revealed that the relative abundance of genera Parasutterella (P = 0.028), Comamonas (P = 0.031), Butyricicoccus (P = 0.049), and Olsenella (P = 0.010) were higher in CM than those in CON; compared with CM, the CG diet had the higher relative abundance of genera Bacteroides (P = 0.024) and Angelakisella (P = 0.020), while the lower relative abundance of genera Olsenella (P = 0.031) and Paraprevotella (P = 0.006). For colonic mucosal microbiota, the relative abundance of genera Duncaniella (P = 0.024), Succiniclasticum (P = 0.044), and Comamonas (P = 0.012) were significantly higher in CM than those in CON. In comparison, the relative abundance of genera Alistipes (P = 0.020) and Campylobacter (P = 0.017) were significantly lower. And the relative abundance of genera Colidextribacter (P = 0.005), Duncaniella (P = 0.032), Christensenella (P = 0.042), and Lawsonibacter (P = 0.018) were increased in the CG than those in the CM. Furthermore, the CG downregulated the relative abundance of genes encoding infectious-disease-parasitic (P = 0.049), cancer-specific-types (P = 0.049), and neurodegenerative-disease (P = 0.037) in colonic microbiota than those in the CM. Overall, these results indicated that maize with different grain sizes might influence the colonic health of weaned lambs by altering the composition of the colonic bacterial community.</p
Solubility and Preferential Solvation of Carbazochrome in Solvent Mixtures of <i>N</i>,<i>N</i>‑Dimethylformamide Plus Methanol/Ethanol/<i>n</i>‑Propanol and Dimethyl Sulfoxide Plus Water
The carbazochrome (3) solubility
in solvent mixtures of DMF (<i>N</i>,<i>N</i>-dimethylformamide,
1) + methanol (2),
DMF (1) + ethanol (2), DMF (1) + <i>n</i>-propanol (2),
and dimethyl sulfoxide (DMSO, 1) + water (2) was measured by the static
method within the temperature range from (278.15 to 318.15) K under
atmospheric pressure, <i>p</i> = 101.0 kPa. The solubility
of carbazochrome increased with rising mass fraction of DMF or DMSO
and temperature. The Jouyban–Acree, van’t Hoff–Jouyban–Acree,
and Apelblat–Jouyban–Acree models were used to correlate
the obtained solubility, and the Apelblat–Jouyban–Acree
model provided better correlation results. The parameters of preferential
solvation (<i>δx</i><sub>1,3</sub>) were acquired
from the mixture properties with the method of inverse Kirkwood–Buff
integrals. The values of <i>δx</i><sub>1,3</sub> changed
nonlinearly with the DMF/DMSO (1) proportion in the studied mixed
solvents. The carbazochrome was solvated preferentially by alcohol
or water in alcohol or water-rich solutions and preferentially solvated
by DMF/DMSO in DMF/DMSO-rich mixtures. It could be speculated that
in DMF/DMSO-rich mixtures the interaction by acidic hydrogen bonding
with the basic sites of carbazochrome played a significant role in
carbazochrome solvation
