Maternal consumption of fish oil protected breast-fed piglets against lipopolysaccharide-induced damage through reshaping of intestinal fatty acids profile.

It has been well documented that n-3 polyunsaturated fatty acids (n-3 PUFA) can alleviate inflammation caused by () lipopolysaccharides (LPS), the etiologic agents that causing yellow or white dysentery in young pigs. However, it remains unclear whether the increase in n-3 PUFA availability could enhance the ability of nursery pigs to resist invasion by . LPS.

A Heuristic-Based Adaptive Iterated Greedy Algorithm for Lot-Streaming Hybrid Flow Shop Scheduling Problem with Consistent and Intermingled Sub-Lots.

Owing to the different quantities and processing times of sub-lots, intermingling sub-lots with each other, instead of fixing the production sequence of sub-lots of a lot as in the existing studies, is a more practical approach to lot-streaming flow shops. Hence, a lot-streaming hybrid flow shop scheduling problem with consistent and intermingled sub-lots (LHFSP-CIS) was studied. A mixed integer linear programming (MILP) model was established, and a heuristic-based adaptive iterated greedy algorithm (HAIG) with three modifications was designed to solve the problem.

Maternal VD supplementation during gestation improves intestinal health and microbial composition of weaning piglets.

Vitamin D (VD) has been reported to improve the reproductive performance of sows. This study was conducted to investigate the long-term effect of maternal VD supplementation during gestation on the intestinal health of piglets. Twenty-three Landrace × Yorkshire gilts were randomly allocated into two groups to receive one of the following two diets during gestation: basal diet (CON group, 800 IU VD per kg diet, = 12) and VD supplemented diet (VD group, 2000 IU VD per kg diet, = 11).

Maternal organic selenium supplementation alleviates LPS induced inflammation, autophagy and ER stress in the thymus and spleen of offspring piglets by improving the expression of selenoproteins.

The thymus and spleen are the main reservoir for T lymphocytes, which can regulate the innate immune response and provide protection against pathogens and tissue damage. Oxidative stress, excessive inflammation, abnormal autophagy and endoplasmic reticulum (ER) stress can all lead to dysfunction of the thymus and spleen. This study was conducted to investigate the effect of maternal 2-hydroxy-4-methylselenobutanoic acid (HMSeBA, an organic Se source) supplementation during pregnancy on the selenoprotein expression, inflammation, ER stress and autophagy of their young offspring's thymus and spleen.

Beneficial effects of a decreased meal frequency on nutrient utilization, secretion of luteinizing hormones and ovarian follicular development in gilts.

Background: Replacement gilts are typically fed ad libitum, whereas emerging evidence from human and rodent studies has revealed that time-restricted access to food has health benefits. The objective of this study was to investigate the effect of meal frequency on the metabolic status and ovarian follicular development in gilts.

Methods: A total of 36 gilts (Landrace × Yorkshire) with an age of 150±3 d and a body weight of 77.

Maternal organic selenium supplementation during gestation improves the antioxidant capacity and reduces the inflammation level in the intestine of offspring through the NF-κB and ERK/Beclin-1 pathways.

Selenium (Se) is postulated to protect against inflammation in the gut by attenuating oxidative stress. This study was conducted to investigate the effects of maternal 2-hydroxy-4-methylselenobutanoic acid (HMSeBA), an organic Se source, on the intestinal antioxidant capacity and inflammation level of the offspring and its possible mechanism. Forty-three sows were randomly assigned to receive one of the following three diets during gestation: control diet, sodium selenite (NaSeO) supplemented diet or HMSeBA supplemented diet, respectively.

Experimental Investigation of the Effect of Purge Flow and Main Flow Interaction in a Low-Speed Turbine Cascade Passage.

In order to protect the vulnerable turbine components from extreme high temperature, coolant flow is introduced from the compressor to the disk cavity, inevitably interacting with the main flow. This paper describes an experimental investigation of the interaction between the main flow and the purge flow in a low-speed turbine cascade with three purge flow rates, Cm = 0, Cm = 1%, and Cm = 2%. In order to study the effect of the interaction between the main flow and the purge flow on the secondary flows, a Rortex method developed by Liu Chaoquan is introduced to identify the vortex in the flow field.

Effect of maternal organic selenium supplementation during pregnancy on sow reproductive performance and long-term effect on their progeny.

Selenium (Se) is an essential trace element for animals and exists in nature in both inorganic and organic forms. Although organic Se is more bioavailable than inorganic Se, there are inconsistent reports on the effect of organic Se on the reproductive performance of sows. This study was conducted to investigate the effect of maternal organic Se (2-hydroxy-4-methylselenobutanoic [HMSeBA]) supplementation on reproductive performance and antioxidant capacity of sows, and the long-term effect on the growth performance and antioxidant capacity of their offspring with or without lipopolysaccharide (LPS) challenge.

Highly Resolved Phylogenetic Relationships within Order Acipenseriformes According to Novel Nuclear Markers.

Order Acipenseriformes contains 27 extant species distributed across the northern hemisphere, including so-called "living fossil" species of garfish and sturgeons. Previous studies have focused on their mitochondrial genetics and have rarely used nuclear genetic data, leaving questions as to their phylogenetic relationships. This study aimed to utilize a bioinformatics approach to screen for candidate single-copy nuclear genes, using transcriptomic data from sturgeon species and genomic data from the spotted gar, .

Benzene-1,3,5-tricarb-oxy-lic acid-1,10-bis-(1,2,4-triazol-1-yl)deca-ne-water (1/1/2).

In the title 1:1:2 association, C(14)H(24)N(6)·C(9)H(6)O(6)·2H(2)O, the alkyl chain in the 1,10-bis-(1,2,4-triazol-1-yl)decane mol-ecule adopts an extended conformation and the dihedral angle between the aromatic rings is 10.28 (13)°. The benzene-1,3,5-tricarb-oxy-lic acid mol-ecule is close to being planar (r.

Bis[μ-2,2'-dimethyl-1,1'-(3-oxapentane-1,5-di-yl)di-1H-benzimidazole-κN:N]bis-[bis-(4-meth-oxy-benzoato)-κO;κO,O'-cobalt(II)].

The complete mol-ecule of the title complex, [Co(2)(C(8)H(7)O(3))(4)(C(20)H(22)N(4)O)(2)], is a dimer of the paddle-wheel-type generated by crystallographic inversion symmetry. The Co(II) ion is penta-coordinated by three O atoms from two 4-meth-oxy-benzoate anions (one bidentate and one monodentate) and two N atoms from two 2,2'-bis-(2-methyl-1H-benzimidazole)-ether ligands. This results in a very distorted trigonal-bipyramidal geometry for the metal ion, with both N atoms in equatorial sites.

An S-curve-based approach of identifying biological sequences.

The main idea of S-curve diagram is to assign different angle values (from 0 degrees to 180 degrees ) to different nucleotide acid residues or to different protein amino acids, and then according to cos alpha(j) and sin alpha(j), the values are accumulated to construct an S-curve diagram, which is in strict one-to-one correspondence with the biological sequence. In addition, the S-curve diagram proves to be without the degeneracy phenomenon, so that both the degeneracy problem represented by diagrams and the problem of visualization for biological sequence data are solved. Meanwhile, a new approach to differentiate the similarity of biological sequences--the degree of similarity--is put forward on the basis of the S-curve diagram.
