Transcriptomic basis of neutrophil ratio variation induced by poly I:C stimulation in porcine peripheral

Haiyan WANG, Qiaoxia ZHANG, Lilin YIN, Xiangdong LIU, Shuhong ZHAO, Mengjin ZHU, Changchun LI

Frontiers of Agricultural Science and Engineering 2017, Volume 4, Issue 3,   Pages 342-352 doi: 10.15302/J-FASE-2017162

Abstract: Neutrophils are vital components of defense mechanisms against invading pathogens and are closely linked with the individual antiviral capacity of pigs and other mammals. Neutrophilia is a well-known clinical characteristic of viral and bacterial infections. Using Affymetrix porcine genome microarrays, we investigated the gene expression profiles associated with neutrophil variation in porcine peripheral blood before and after polyriboinosinic-polyribocytidylic acid stimulation. Transcriptomic analysis showed 796 differentially expressed genes (DEGs) in extreme response (ER) pigs and 192 DEGs in moderate response (MR) pigs. Most DEGs were related to immune responses, included , , , , , , , and . Gene ontology analysis indicated that the DEGs of both ER and MR pigs were involved in common biological processes, such as cell proliferation, growth regulation, immune response, inflammatory response and cell activation. The ER and MR groups also showed differences in DEGs involved in biological processes. DEGs involved in cell division and cell cycle were specifically found in the ER pigs, whereas DEGs involved in cell migration were specifically found in the MR pigs. The study provides a basic understanding of the molecular basis for the antiviral capacity of pigs and other mammals.

Chemical poison and regeneration of SCR catalysts for NO<i>xi>

Junhua LI,Yue PENG,Huazhen CHANG,Xiang LI,John C. CRITTENDEN,Jiming HAO

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 3,   Pages 413-427 doi: 10.1007/s11783-016-0832-3

Abstract: Selective catalytic reduction (SCR) of NO with NH is an effective technique to remove NO from stationary sources, such as coal-fired power plant and industrial boilers. Some of elements in the fly ash deactivate the catalyst due to strong chemisorptions on the active sites. The poisons may act by simply blocking active sites or alter the adsorption behaviors of reactants and products by an electronic interaction. This review is mainly focused on the chemical poisoning on V O -based catalysts, environmental-benign catalysts and low temperature catalysts. Several common poisons including alkali/alkaline earth metals, SO and heavy metals etc. are referred and their poisoning mechanisms on catalysts are discussed. The regeneration methods of poisoned catalysts and the development of poison-resistance catalysts are also compared and analyzed. Finally, future research directions in developing poisoning resistance catalysts and facile efficient regeneration methods for SCR catalysts are proposed.

High <i>Sni>-2 Docosahexaenoic Acid Lipids for Brain Benefits, and Their Enzymatic Syntheses: A Review Review

Jun Jin, Qingzhe Jin, Xingguo Wang, Casimir C. Akoh

Engineering 2020, Volume 6, Issue 4,   Pages 424-431 doi: 10.1016/j.eng.2020.02.009

Abstract:

The normal development and maintenance of central neural functions are highly correlated with the amount of docosahexaenoic acid (DHA; ω-3 fatty acid) accumulated in the brain. DHA incorporated at the sn-2 position of lipids is well absorbed by intestinal mucosa and utilized efficiently in vivo. However, modern consumers have a reduced direct intake of DHA and increased intake of saturated fats or ω-6 fatty acid oils, resulting in behavioral and neurophysiological deficits. To provide an understanding of the integrated beneficial effects of DHA on the human brain, this review introduces the positional difference (sn-2 and sn-1,3 positions) of DHA on a glycerol skeleton in natural fats and oils, and further discusses the possible functional mechanism regarding DHA supplementation and the gut-brain axis. The multiple bidirectional routes in this axis offer a novel insight into the interaction between DHA supplementation, the gut microbiota, and brain health. To achieve high sn-2 DHA in diets, it is suggested that sn-2 DHA lipids be enzymatically produced in more efficient and economical ways by improving the specific activities of lipases and optimizing the purification procedures. These types of diets will benefit individuals with strong needs for sn-2 ω-3 lipids such as infants, children, and pregnant and lactating women.

Lipase-Catalyzed Synthesis of <i>Sni>-2 Palmitate: A Review Review

Wei Wei, Cong Sun, Xiaosan Wang, Qingzhe Jin, Xuebing Xu, Casimir C. Akoh, Xingguo Wang

Engineering 2020, Volume 6, Issue 4,   Pages 406-414 doi: 10.1016/j.eng.2020.02.008

Abstract:

Human milk fat (HMF) is an important source of nutrients and energy for infants. Triacylglycerols (TAGs) account for about 98% of HMF and have a unique molecular structure. HMF is highly enriched in palmitic acid (PA) at the sn-2 position of the glycerol backbone (more than 70%) and in unsaturated fatty acids at the sn-1,3 position. The specific TAG structure in HMF plays a valuable function in infant growth. Sn-2 palmitate (mainly 1,3-dioleoyl-2-palmitoyl-glycerol) is one of the structured TAGs that is commonly supplemented into infant formula in order to enable it to present a similar structure to HMF. In this review, the development of the lipase-catalyzed synthesis of sn-2 palmitate over the last 25 years are summarized, with a focus on reaction schemes in a laboratory setting. Particular attention is also paid to the commercialized sn-1,3 regioselective lipases that are used in structured TAGs synthesis, to general methods of TAG analysis, and to successfully developed sn-2 palmitate products on the market. Prospects for the lipase-catalyzed synthesis of sn-2 palmitate are discussed.
