Abstract
As human life expectancy increases, the incidence of neurodegenerative diseases in older adults has increased in parallel. Walnuts contain bioactive peptides with demonstrated neuroprotective effects, making them a valuable addition to the diet. We here present a comprehensive review of the various methods used to prepare, isolate, purify, and identify the neuroprotective peptides found in walnuts. We further summarise the different approaches currently used to evaluate the activity of these peptides in experimental settings, highlighting their potential to reduce oxidative stress, neuroinflammation, and promote autophagy, as well as to regulate the gut microflora and balance the cholinergic system. Finally, we offer suggestions for future research concerning bioavailability and improving or masking the bitter taste and sensory properties of final products containing the identified walnut neuroprotective peptides to ensure successful adoption of these peptides as functional food ingredients for neurohealth promotion.

Abstract
A major active constituent of Moringa oleifera Lam. is 4-[(α-L-rhamnose oxy) benzyl] isothiocyanate (MITC). To broaden MITC's application and improve its biological activity, we synthesized a series of MITC quinazolinone derivatives and evaluated their anticancer activity. The anticancer effects and mechanisms of the compound with the most potent anticancer activity were investigated further. Among 16 MITC quinazolinone derivatives which were analyzed, MITC-12 significantly inhibited the growth of U251, A375, A431, HCT-116, HeLa, and MDA-MB-231 cells. MITC-12 significantly inhibited U251 cell proliferation in a time- and dose-dependent manner and decreased the number of EdU-positive cells, but was not toxic to normal human gastric mucosal cells (GES-1). Further, MITC-12 induced apoptosis of U251 cells, and increased caspase-3 expression levels and the Bax:Bcl-2 ratio. In addition, MITC-12 significantly decreased the proportion of U251 cells in the G1 phase and increased it in S and G2 phases. Transcriptome sequencing showed that MITC-12 had a significant regulatory effect on pathways regulating the cell cycle. Further, MITC-12 significantly decreased the expression levels of the cell cycle-related proteins CDK2, cyclinD1, and cyclinE, and increased those of cyclinA2, as well as the p-JNK:JNK ratio. These results indicate that MITC-12 inhibits U251 cell proliferation by inducing apoptosis and cell cycle arrest, activating JNK, and regulating cell cycle-associated proteins. MITC-12 has potential for use in the prevention and treatment of glioma.

Abstract
High-fat diet (HFD)-induced obesity results in bone loss associated with an imbalanced gut microbiota and altered immune status. Probiotics are live microorganisms that are beneficial to the host and are important in maintaining bone health and gut homeostasis. In this study, the probiotic Lactobacillus coryniformis subsp. torquens (T3L) was isolated from traditional yak milk cheese produced in Lhasa and showed distinct acid and bile salt resistance as potential probiotics. Our data indicated that T3L not only reversed HFD-induced gut dysbiosis, as indicated by decreased Firmicutes-to-Bacteroidetes ratios but also reduced bone loss. The anti-obesity, microbiome-modulating, and bone-protective effects were transmissible via horizontal faeces transfer from T3L-treated mice to HFD-fed mice. The protective effects of T3L on bone mass were associated with regulatory T (Treg) cell-mediated inhibition of osteoclast differentiation. Our data indicate that T3L is a regulator of the gut microbiota and bone homeostasis in an animal model.

Abstract
Background Alzheimer's Disease (AD) and Type 2 Diabetes Mellitus (DM) have an increased incidence in modern society. Although more and more evidence has supported that DM is prone to AD, the interrelational mechanisms remain fully elucidated. Purpose The primary purpose of this study is to explore the shared pathophysiological mechanisms of AD and DM. Methods Download the expression matrix of AD and DM from the Gene Expression Omnibus (GEO) database with sequence numbers GSE97760 and GSE95849, respectively. The common differentially expressed genes (DEGs) were identified by limma package analysis. Then we analyzed the six kinds of module analysis: gene functional annotation, protein-protein interaction (PPI) network, potential drug screening, immune cell infiltration, hub genes identification and validation, and prediction of transcription factors (TFs). Results The subsequent analyses included 339 common DEGs, and the importance of immunity, hormone, cytokines, neurotransmitters, and insulin in these diseases was underscored by functional analysis. In addition, serotonergic synapse, ovarian steroidogenesis, estrogen signaling pathway, and regulation of lipolysis are closely related to both. DEGs were input into the CMap database to screen small molecule compounds with the potential to reverse AD and DM pathological functions. L-690488, exemestane, and BMS-345541 ranked top three among the screened small molecule compounds. Finally, 10 essential hub genes were identified using cytoHubba, including PTGS2, RAB10, LRRK2, SOS1, EEA1, NF1, RAB14, ADCY5, RAPGEF3, and PRKACG. For the characteristic Aβ and Tau pathology of AD, RAPGEF3 was associated significantly positively with AD and NF1 significantly negatively with AD. In addition, we also found ADCY5 and NF1 significant correlations with DM phenotypes. Other datasets verified that NF1, RAB14, ADCY5, and RAPGEF3 could be used as key markers of DM complicated with AD. Meanwhile, the immune cell infiltration score reflects the different cellular immune microenvironments of the two diseases. Conclusion The common pathogenesis of AD and DM was revealed in our research. These common pathways and hub genes directions for further exploration of the pathogenesis or treatment of these two diseases.

Abstract
Ulcerative colitis is a chronic inflammatory bowel disease (IBD), but progress in exploring its pathogenesis and finding effective drugs for its prevention and treatment has stalled in recent years. The seeds of Moringa oleifera Lam. are rich in proteins known to have multiple physiological activities. In our earlier work, we had isolated and purified a peptide (MOP) having the sequence KETTTIVR, from M. oleifera seeds; however, its anti-inflammatory activity and mechanism in vivo were unclear. Here we used the dextran sulfate sodium (DSS)-induced colitis model to study the anti-inflammatory activity and mechanism of this MOP. Our results are the first to show that MOP can ameliorate the pathological phenotype, inflammation, and intestinal barrier disruption in mice with colitis. Furthermore, RNA sequencing revealed that MOP inhibits the Janus kinase/signal transducer and activator of transcription (JAK-STAT) pathway activation. Next, by using 16s rRNA gene sequencing, we found that MOP can ameliorate DSS-induced gut microbiota dysbiosis. In addition, an untargeted metabolomics analysis suggested that MOP is able to modulate the level of lipid and amino acid metabolites in IBD-stricken mice. Altogether, these results indicate that MOP ameliorates colitis by remodeling intestinal mucosal barrier by inhibiting JAK-STAT pathway’s activation and regulating gut microbiota and its metabolites, thus providing a basis for further processing and design of bioactive foods from M. oleifera seeds.

Abstract
Ginseng has been widely applied in clinical practice, but the cultivation age cannot be ignored as it influences the quality of ginseng and its products. In this work, different cultivation ages of fresh ginseng (FG) from four to seven years were analysed by UPLC-Q-TOF-MS/MS. Principal component analysis and supervised orthogonal partial least squared discrimination analysis, which belong to the normal method of multivariate statistical analysis, were applied to discover the characteristic components of FG at different cultivation ages. The components of new type of red ginseng (NRG) derived from FG at different cultivation ages were compared by HPLC analysis. The pharmacological anti-inflammatory activity was evaluated by ELISA and qPCR. The result showed that the characteristic components of both 6- and 7-year-old ginseng were ginsenoside Rb1, mal-ginsenoside Rb1, ginsenoside Rc, mal-ginsenoside Rc, mal-ginsenoside Rb1 isomer, and mal-ginsenoside Rb2. Moreover, the characteristic components of both 4- and 5-year-old ginseng were ADP-glucose and 3-hydroxyhexanoyl CoA. In addition, 6-year-old NRG has higher rare ginsenosides than 4-year-old NRG, which possesses great anti-inflammatory activity in vitro. The results reveal the ginsenoside transformation law of NRG processing and suggest that the cultivation age of FG influences the content of ginsenosides in NRG. Therefore, 6-year-old ginseng is more suitable for red ginseng processing and clinical use.

Abstract
BACKGROUND Dorper sheep is an ideal breed for improvement, with higher meat production and increased adaptability. Artificial insemination is an efficient technique for Dorper genetic improvement and reproduction management. However, there is no uniform diluent for Dorper semen dilution. OBJECTIVE To compare the effects of vitamin B12 (VB12) and skimmed milk diluents on sperm motility at different ratios and time points, and the effects on conception rate. MATERIALS AND METHODS We detected the effect of diluents on sperm density, deformity, motility and conception rate of Dorper sheep. RESULTS We found the optimal dilution ratio of skimmed milk is 1:3. Compared to VB12, skimmed milk at 1:3 ratio prolonged semen storage time (48 h vs. 18 h, storage at a low temperature of 4°C) and increased the survival index of sperm (44.7 ± 2.8 vs. 18.5 ± 0.6, P<0.01). CONCLUSION Skimmed milk is more effective, nutritious and convenient than vitamin B12, representing a more advantageous diluent.

Abstract
Objective: To investigate the abnormal functional connectivity between sublaterodorsal nucleus (SLD) and the brain motor areas in Parkinson's disease with or without rapid-eye-movement (REM) sleep behavior disorder by resting state functional magnetic resonance imaging (rfMRI). Methods: A total of 64 subjects recruited in the Department of Neurology, the People's Hospital of Zhengzhou University were enrolled in this study from August 2014 to December 2017 according to international diagnosis criteria, 20 cases with PD-RBD (PD-RBD group), 23 cases without PD-nRBD (PD-nRBD group) and 21 age, gender-matched healthy controls (HC group). All subjects were examined by Hoehn-Yahr, UPDRS-Ⅲ and rfMRI. Resluts: UPDRS-Ⅲ scores and Hoehn-Yahr staging were showed significantly different from that in the HC group(KW=-27.35, P<0.001) but showed no significantly difference from that in the PD-nRBD group(KW=6.01, P=0.807). Compared with the control group, the FC analysis showed reduced correlations from the left SLD to the right orbital middle frontal gyrus(T=-4.567 8, P<0.001), the left cingulate gyrus(T=-3.196 0,P<0.001), the left cerebellum(T=-4.267 0,P<0.001) and the right midbrain(T=-4.773 7, P<0.001), from the right SLD to the bilateral cerebellum (T(left)=-5.040 1, T(right)=-4.210 5, P<0.001), the left precuneus(T=-4.468 2,P<0.001) and the left precentral gyrus (T=-4.473 9,P<0.001) in the PD-RBD. The correlations between the left SLD and left cerebellum, right midbrain and between the right SLD and left precuneus, left precentral gyrus were negative correlated with the motor functional tests. Conclusions: There are abnormal functional connectivity from the SLD to the motor areas in PD-RBD patients, leading to clinical PD-RBD motor symptoms and movement disorders.

Abstract
Microglia are glial-immune cells that are essential for the function and survival of the central nervous system. Microglia not only protect neural tissues from immunological insults, but also play a critical role in neural development and repair. However, little is known about the biology of microglia in the cochlea, the auditory portion of the inner ear. In this study, we detected TMEM119+, CD11b+, CD45+ and Iba1+ populations of cells in the rat cochlea, particularly in Rosenthal's canal, inner sulcus and stria vascularis. Next, we isolated and enriched the population of CD11b+ cells from the cochlea and immortalized these cells with the 12S E1A gene of adenovirus in a replication-incompetent retroviral vector to derive a novel microglial cell line, designated Mocha (microglia of the cochlea). The resulting Mocha cells express a number of markers consistent with microglia and respond to lipopolysaccharide (LPS) stimulation by upregulation of genes (Cox2, ICAM-1, Il6r, Ccl2, Il13Ra and Il15Ra) as well as releasing cytokines (IL-1beta, IL-12, IL-13 and RANTES). As evidence of microglial function, Mocha cells phagocytose fluorescent beads at 37°C, but not at 4°C. The expression pattern of microglial markers in Mocha cells suggests that immortalization leads to a more primitive phenotype, a common phenomenon in immortalized cell lines. In summary, Mocha cells display key characteristics of microglia and are now available as a useful model system for the study of cochlear microglial behavior, both in vitro and in vivo.

Abstract
The primary aims of this study were to investigate mitochondrial metabolism during experimental allergic encephalomyelitis (EAE) animal model axonal injury and to determine the correlation among neurological function scores, pathological changes, and the activities of the BB isoenzyme of creatine kinase (CK-BB), catalase (CAT), and calpain in the brain tissues of EAE rats. Another goal was to preliminarily define the mechanism of mitochondrial metabolism resulting from the effect of beta 2 adrenergic agonists in the process of EAE animal model axonal damage. EAE was induced in specific pathogen free Wistar rats by guinea pig spinal cord homogenate, complete Freund's adjuvant, and pertussis vaccine. We recorded the behavioral change in EAE rats, detected pathological changes in central nervous tissue, and observed the changes of the CK-BB, CAT, and calpain in the EAE rat brain and spinal cord. The results indicated that the average neurologic function score increased in the EAE group compared to that of the controls (P < 0.01). In addition, CAT and CK-BB activities significantly decreased and the calpain activity significantly increased compared with those of the control group (P < 0.05). The decrease of the activity of central nervous CK-BB and CAT content, as well as the increase of calpain activity at the highest time point were considered to be the consequences of EAE. Furthermore, the results revealed that use of salbutamol could alleviate disease symptoms and reduce the recurrence of the EAE disease.

Abstract
During 2005-2008, field studies were conducted at two locations in Chongqing, China, to assess the potential effects of transgenic rice expressing Bacillus thuringiensis (Bt) Cry1Ab protein on the nontarget ground-dwelling collembolan community in three postharvest seasons. Collembolans in non-Bt and Bt rice fields were sampled with pitfall traps during each of two postharvest seasons of 2005/2006 and 2006/2007 and litterbag traps during each of three postharvest seasons of 2005/2006, 2006/2007, and 2007/2008. Ground-dwelling collembolans in rice fields during the postharvest seasons were abundant, whereas community densities varied considerably between the two locations and among the three seasons. A total of 67,310 collembolans, representing three species, Entomobrya griseoolivata, Hypogastrura matura, and Bourletiella christianseni, were captured during the three postharvest seasons. E. griseoolivata was the predominant species, accounting for 87.7% of the total captures, followed by H. matura (10.7%) and B. christianseni (1.6%). In general, there were no significant differences in species compositions and abundances of each species between Bt and non-Bt paddy fields, suggesting no significantly impact of plant residues of Cry1Ab rice on collembolan communities during postharvest seasons.

Abstract
Cotyledons, each with a 1-2 mm petiole at its base, were cut from axenic seedlings and infected with Agrobacterium tumefaciens. After 2-3 days of cocultivation, the cotyledon explants were transferred to MS selection medium containing 15 mg/L kanamycin and 4.5 mg/L 6-BA to induce shoot differentiation. Kanamycin-resistant shoots were subcultured on selection medium with 20-50 mg/L kanamycin for 3-6 months for eliminating escaped non-transformants, and then rooted on MS medium containing 25 mg/L kanamycin and 0.1 mg/L NAA. Whole plants were transplanted into soil and grew in the field. DNA Southern blot hybridization and polymerase chain reaction showed that some of the plants were positive when probed with the insecticidal crystal protein gene. The transgenic plants exhibited tolerant to pest insects such as Laphygma exigua and Pieris rapae in leaf feeding experiments Kanamycin-resistance and insect-resistance were maintained in the progeny. The foreign genes were delivered to the progeny according to Mendelian Law of single gene segregation.

Abstract
Cotyledons cut from axenic seedlings were immersed inAgrobacterium tumefaciens suspension which was treated with acetosyringone and nopaline at low pH overnight. The infected cotyledon explants were cultured on MSB medium (MS salts + B5 Vitamins) containing 6-BA 3mg/1 for 2-3 days, and transferred onto selective medium (MSB with kanamycin 50-100 mg/l). Kanamycin-resistant shoots were selected. More than 60 regenerated plants were obtained. About 60% of the plants showed high NPT II activity. Southern blot hybridization showed that some of the plants gave a positive signal with the insecticidal crystal protein gene (cry IA gene) probe, and exhibited tolerant to insects such asPieris rapae (cabbage caterpillar) in leaf feeding experiments. Kanamycin-resistance and insect-resistance were maintained in the progeny.

Abstract
An insect larval toxin designated CryII is produced by several subspecies of Bacillus thuringiensis and differs from the other major delta-endotoxins in these bacteria in its size, toxicity profile and presence as part of an operon with three open reading frames (ORF). Such an operon from a novel B. thuringiensis isolate has been cloned and differs from one previously characterized in the following ways: (a) the size and number of amino acid repeats in one of the ORFs; (b) the smaller size of the CryII protoxin and the presence of a unique 110-kDa CryII-related antigen; and (c) high larvicidal activity for a particular Lepidopteran but low activity for a Dipteran. Various subclones of this operon were introduced into a plasmid-free B. thuringiensis strain and only the cryII gene was found to be necessary for protoxin accumulation.
