Mammary metabolism and colostrogenesis in sows during late gestation and the colostral period.

The aims of this study were to investigate 1) the effect of high dietary fiber (DF; 19.3% to 21.7%) supplemented to late gestating sows on mammary uptake and metabolism of energy substrates as well as colostrum production and 2) the ontogeny of colostral fat and lactose synthesis using mammary carbon balance, and colostral protein using IgG as a biomarker.

Effect of maternal or post-weaning methyl donor supplementation on growth performance, carcass traits, and meat quality of pig offspring.

Background: Limited studies have examined links between maternal methyl donor (MET) supplementation and the growth-development characteristics of offspring, and possible underlying mechanisms for such links. This study investigated the effect of maternal or post-weaning MET-supplementation on growth performance, carcass characteristics, and meat quality of the finishing (d 180) offspring. Twenty-four sows were placed on a control (C) or MET-supplemented diet during pregnancy and lactation.

Retinoic Acid Receptor α Knockdown Suppresses the Tumorigenicity of Esophageal Carcinoma via Wnt/β-catenin Pathway.

Background: Aberrant expression of retinoic acid receptor α (RARα) was correlated with diverse carcinomas such as acute promyelocytic leukemia and colorectal carcinoma. Nevertheless, the function and mechanism of RARα in esophageal carcinoma (EC) remain unclear.

Aim: To investigate the expression of RARα in EC and its effect in the tumorigenesis of EC.

Methyl donors dietary supplementation to gestating sows diet improves the growth rate of offspring and is associating with changes in expression and DNA methylation of insulin-like growth factor-1 gene.

The study aimed to investigate the effects of maternal dietary methyl donors on the performance of sows and their offspring, and the associated hepatic insulin-like growth factor-1 (IGF-1) expression of the offspring. A total of 24 multiparous sows were randomly fed the control (CON) or the CON diet supplemented with methyl donors (MD) at 3 g/kg betaine, 15 mg/kg folic acid, 400 mg/kg choline and 150 μg/kg VB , from mating until delivery. After farrowing, sows were fed a common lactation diet through a 28-days lactation period and six litters per treatment were selected to be fed until at approximately 110 kg BW.

[Effects of phosphorus application rates and depths on P utilization and loss risk in a maize-soybean intercropping system].

In order to explore the advantage of intercropping on phosphorus (P) efficient utilization and the reduction of soil P loss, a field experiment in a maize-soybean intercropping system, which included three P application (PO) rates (CP: 168 kg·hm; RP: 135 kg·hm; RP: 101 kg·hm) and three P application depths (D: applied in 5 cm depth; D: applied in 15 cm depth; D: 1/2 of P fertilizer applied in 5 cm depth and another 1/2 in 15 cm depth) was carried out to analyze the effects of P application rates and depth on crop aboveground biomass, grain yield, crop P uptake, soil total and available P contents, and soil P adsorption-desorption characteristics. Compared with control treatment, the aboveground biomass, grain yield, crop P uptake, soil total P, and available P content were increased significantly by P application, regardless of P rate and application depth. Under the same application depth, RP had similar grain yield but higher crop P uptake compared with CP, and thus higher P apparent utilization efficiency.

One-stage Pelnac Reconstruction in Full-thickness Skin Defects with Bone or Tendon Exposure.

Dermal regeneration template, such as Integra and Pelnac, was originally designed for treating large area burn injury by inducing regeneration of dermis. To date, it has been widely applied in various acute and chronic wound sites. The present study demonstrated that application of artificial dermis alone induced 1-stage wound healing for wounds with bone or tendon exposure that should usually be repaired by flap surgery.

Inflammation-restricted anti-inflammatory activities of a N-acylethanolamine acid amidase (NAAA) inhibitor F215.

N-Acylethanolamine acid amidase (NAAA) is a cysteine enzyme that catalyzes the hydrolysis of palmitoylethanolamide (PEA). Pharmacological blockage of NAAA elevates PEA levels and exerts powerful anti-inflammatory activities. We have recently identified a highly potent NAAA inhibitor F215.

Effects of mono-component xylanase supplementation on nutrient digestibility and performance of lactating sows fed a coarsely ground diet.

A total of 30 cross-bred (Danish Landrace × Yorkshire) multiparous sows (parity 2 to 5) were used. Sows were fed a standard gestation diet from mating until day 108 of gestation, and then stratified for BW (295.

Microbial Mechanistic Insight into the Role of Inulin in Improving Maternal Health in a Pregnant Sow Model.

General consumption of "western diet" characterized by high refined carbohydrates, fat and energy intake has resulted in a global obesity epidemics and related metabolic disturbance even for pregnant women. Pregnancy process is accompanied by substantial hormonal, metabolic and immunological changes during which gut microbiota is also remarkably remodeled. Dietary fiber has been demonstrated to have a striking role in shifting the microbial composition so as to improve host metabolism and health in non-pregnant individuals.

Mn(OAc)-Promoted Oxidative C-P Bond Formation through C-C and P-H Bond Cleavage: Access to β-Ketophosphonates.

The Mn(OAc)-promoted oxidative phosphonylation of N,N-dimethylenaminones with H-phosphonates, involving a chemo- and regioselective C-C bond cleavage and C-P bond formation in one step, provided successfully functionalized β-ketophosphonates under mild reaction conditions. Oxidative C-H/P-H cross-coupling reactions via C-C(C═O) bond cleavage and mechanistic studies are conducted preliminarily, and a possible mechanism is proposed. This novel method proceeds in good to excellent yields, shows operational simplicity, broad substrate scope, and large-scale preparation.

Programmed Nanococktail Based on pH-Responsive Function Switch for Self-Synergistic Tumor-Targeting Therapy.

Tumor-targeting combination chemotherapy is an important way to improve the therapeutic index and reduce the side effects as compared to traditional cancer treatments. However, one of the major challenges in surface functionalization of nanoparticle (NP) is accomplishing multiple purposes through one single ligand. Upon such consideration, methotrexate (MTX), an anticancer drug with a targeting moiety inspired by the similar structure of folate, could be used to covalently link with lipid-polymer conjugate (DSPE-PEG) via a pH-sensitive dynamic covalent imine (CH═N) bond to synthesize the acid-induced function "targeting-anticancer" switching DSPE-PEG-CH═N-MTX.

Tensor Factorization for Low-Rank Tensor Completion.

Recently, a tensor nuclear norm (TNN) based method was proposed to solve the tensor completion problem, which has achieved state-of-the-art performance on image and video inpainting tasks. However, it requires computing tensor singular value decomposition (t-SVD), which costs much computation and thus cannot efficiently handle tensor data, due to its natural large scale. Motivated by TNN, we propose a novel low-rank tensor factorization method for efficiently solving the 3-way tensor completion problem.

Beneficial effects of dietary soluble fiber supplementation in replacement gilts: Pubertal onset and subsequent performance.

The aim of this study was to examine the effects of soluble fiber supplementation prior to puberty on age at puberty and subsequent reproductive performance of gilts. A total of 136 gilts of similar body weight (BW, 60.59±7.

Dually folate/CD44 receptor-targeted self-assembled hyaluronic acid nanoparticles for dual-drug delivery and combination cancer therapy.

Nanoparticles (NPs) functionalized with targeting ligands have shown promise, but are still limited by their nonspecific uptake by certain healthy tissues and cells that express low or even comparable levels of receptors. To increase their accumulation at tumor sites while decreasing the unintended toxicity, a possible solution is the involvement of two separate tumor-specific ligands in the localization. In this study, a dual tumor-targeting drug-loaded NP system was self-assembled by the amphiphilic conjugate of methotrexate-hyaluronic acid-octadecylamine (MTX-HA-OCA) with curcumin (CUR) encapsulated within the hydrophobic core (designated as MTX-HA-OCA/CUR NPs).

The novel autophagy inhibitor elaiophylin exerts antitumor activity against multiple myeloma with mutant TP53 in part through endoplasmic reticulum stress-induced apoptosis.

Elaiophylin is a natural compound and a novel and potent inhibitor of late stage autophagy with outstanding antitumor activity in human ovarian cancer cells. However, the possible biologic effects and functional linkage between elaiophylin and multiple myeloma (MM) have not been explored. This study aimed to assess the effect of elaiophylin on MM cells with mutant TP53 and the possible molecular mechanism.

Expansion and activation of granulocytic, myeloid-derived suppressor cells in childhood precursor B cell acute lymphoblastic leukemia.

Precursor B cell acute lymphoblastic leukemia (B-ALL) is a B cell-derived, malignant disorder with the highest incidence among children. In addition to the genetic abnormality, a dysregulated immune system also has an important role in the pathogenesis of B-ALL. Myeloid-derived suppressor cells (MDSCs) represent one of the key drivers in immune tolerance against tumor cells, including various solid tumors and hematologic malignancies.

Design of a novel curcumin-soybean phosphatidylcholine complex-based targeted drug delivery systems.

Recently, the global trend in the field of nanomedicine has been toward the design of combination of nature active constituents and phospholipid (PC) to form a therapeutic drug-phospholipid complex. As a particular amphiphilic molecular complex, it can be a unique bridge of traditional dosage-form and novel drug delivery system. In thisarticle, on the basis of drug-phospholipid complex technique and self-assembly technique, we chose a pharmacologically safe and low toxic drug curcumin (CUR) to increase drug-loading ability, achieve controlled/sustained drug release and improve anticancer activity.

Oncogenic retinoic acid receptor γ knockdown reverses multi-drug resistance of human colorectal cancer via Wnt/β-catenin pathway.

Retinoic acid receptor γ (RARγ), a unique member of the nuclear receptor superfamily, plays an important role in the progression of several cancers such as hepatocellular carcinoma, esophageal cancer, and cholangiocarcinoma. However, little is known about the regulatory mechanism of the RARγ expression in colorectal cancer (CRC) progression. In the present study, we found that RARγ was frequently overexpressed in human CRC specimens and CRC cell lines, and it mainly resided in the cytoplasm in CRC specimens.

The role of 5-hydroxymethylcytosine in melanoma.

Malignant melanoma is a highly aggressive neoplasia of melanocytic origin. In part because of the lack of effective treatment methods, the incidence and mortality rates of this disease continue to increase. Rapidly accumulating evidence suggests that dysregulation of epigenetic mechanisms, including DNA methylation/demethylation, chromatin modification, and remodeling, and diverse activities of noncoding RNAs, play a central role in the pathogenesis of melanoma.

Transfer of -hydroxy--methylbutyrate from sows to their offspring and its impact on muscle fiber type transformation and performance in pigs.

Background: Previous studies suggested that supplementation of lactating sows with -hydroxy--methylbutyrate (HMB) could improve the performance of weaning pigs, but there were little information in the muscle fiber type transformation of the offspring and the subsequent performance in pigs from weaning through finishing in response to maternal HMB consumption. The purpose of this study was to determine the effect of supplementing lactating sows with HMB on skeletal muscle fiber type transformation and growth of the offspring during d 28 and 180 after birth. A total of 20 sows according to their body weight were divided into the control (CON,  = 10) or HMB groups (HMB,  = 10).

Positive feedback loop of IL-1β/Akt/RARα/Akt signaling mediates oncogenic property of RARα in gastric carcinoma.

Abnormal expression and function of retinoic acid receptor α (RARα) have been reported to be associated with various cancers including acute promyelocytic leukemia and hepatocellular carcinoma. However, the role and the mechanism of RARα in gastric carcinoma (GC) were unknown. Here, the expression of RARα was frequently elevated in human GC tissues and cell lines, and its overexpression was closely correlated with tumor size, lymph node metastasis and clinical stages in GC patients.

Oncogenic retinoic acid receptor α promotes human colorectal cancer growth through simultaneously regulating p21 transcription and GSK3β/β-catenin signaling.

Retinoic acid receptor α (RARα) plays important roles in the progression of several cancers such as leukemia, breast cancer, and lung cancer. In this study, we demonstrated that RARα protein was frequently overexpressed in human CRC specimens and CRC cell lines. RARα knockdown decreased cell survival, proliferation, and colony formation in vitro and tumorigenic potential in nude mice.
