The sensilla type, number and distribution in male and female adults of Carabus elysii Thomson, 1856 (Coleoptera: Carabidae) were studied using scanning electron microscopy. The results showed that there are seven categories and 12 types of sensilla in C. elysii adults: three types of S.Ch, three types of S.T, two types of S.B and one each of B.B, S.Co, S.Ca and S.Cam. There is no difference between male and female in the types of sensilla. Apart from the significant difference in the number and distribution of S.B.2, S.Co and S.Ca between male dorsal and ventral surfaces, there are no significant differences between male and female antennae. In general, the number of sensilla in females is larger than that in males. The results provide a basic reference for future ultrastructure, electrophysiological, and comparative behavioral studies of Carabus species.

MiRNAs regulate the expression of target genes in diverse cellular processes and hence play important roles in different physiological processes, yet little is known about the stomach microRNAome (miRNAome) of the Tibetan pig. The objective of this experiment was to investigate differentially expressed stomach miRNAs participating in digestion. Firstly, we isolated total RNA by Trizol reagent from three Tibetan and three Yorkshire purebred pigs stomach samples at 90-day-old. Secondly, a comprehensive analysis of Tibetan and Yorkshire pig stomach miRNAomes was performed by small RNA sequencing in the Illumina HiSeq 2000 system. Finally, SYBR Green Real-time RT-PCR was performed to validate the differentially expressed miRNAs. We identified 318 unique miRNAs, 260 were co-expressed in both libraries, 17 and 31 miRNAs were specifically expressed in Tibetan and Yorkshire pigs respectively. Fifty six differentially expressed miRNAs were identified by the identifying differentially expressed genes 6 (IDEG6). Kyoto encyclopedia of genes and genomes analysis revealed that some of the differentially expressed miRNAs were associated with protein and fat digestion. Two differentially expressed miRNAs (miR-214-3p and ssc-un39) participating in the digestion of lipid were identified. Additionally, qRT-PCR results suggested that a higher expression of miR-214-3p in the Tibetan pig stomach could lead to relatively lower expression of calcium-dependent phospholipase A2, which is an enzyme important for the digestion of glycerol phospholipid. This study has delineated the different stomach miRNAs expression patterns of Tibetan and Yorkshire pigs, which would help explain the regulatory mechanisms of miRNAs in digestion of Tibetan pigs, and contribute to utilize a the unique digestion merits of Tibetan pig in future porcine hybridization breeding.

Coordinated multiple points transmission and reception (CoMP) technology is used to mitigate the inter-cell interference, and increase cell average user normalized throughput and cell edge user normalized throughput. There are two kinds of radio resource schedule strategies in LTE-A/5G CoMP system, and they are called centralized scheduling strategy and distributed scheduling strategy. The regional centralized scheduling cannot solve interference of inter-region, and the distributed scheduling leads to worse efficiency in the utilize of resources. In this paper, a novel distributed scheduling scheme named 9-Cell alternate authorization (9-CAA) is proposed. In our scheme, time-domain resources are divided orthogonally by coloring theory for inter-region cooperation in 9-Cell scenario [6]. Then, we provide a formula based on 0-1 integer programming to get chromatic number in 9-CAA. Moreover, a feasible optimal chromatic number search algorithm named CNS-9CAA is proposed. In addition, this scheme is expanded to 3-Cell scenario, and name it 3-Cell alternate authorization (3-CAA). At last, simulation results indicate that 9/3-CAA scheme exceed All CU CoMP, 9/3C CU CoMP and DLC resource scheduling scheme in cell average user normalized throughput. Especially, compared with the non-CoMP scheme as a benchmark, the 9-CAA and 3-CAA have improved the edge user normalized throughput by 17.2% and 13.0% respectively.

<P>A total of 60 weaned pigs with initial body weight (BW) of 8.51 ± 0.42 kg (28 d of age) were randomly divided into 2 groups of 30 each consisted of 6 pens with 2 gilts and 3 borrows and supplemented (treatment) 5.3×108 cfu/kg Lactobacillus plantarum GB805 in addition to basal diet offered during d 0 to 14 and d 15 to 42 (control). During the total trial period or different phases of trial, pigs fed L. plantarum diet had a higher (P less than 0.05) ADG, ADFI and feed efficiency. At the end of experiment, dietary L. plantarum supplementation improved (P less than 0.05) the apparent total tract digestibility of dry matter, nitrogen and the fecal Lactobacillus populations (P less than 0.05) while the fecal E.coli populations were decreased (P less than 0.05). In conclusion, dietary supplementation of L. plantarum GB805 had positive influence on growth rate, nutrient digestibility and gut microbial balance and its supplementation recommended to weaning pigs.</P>
Molecular functions and therapeutic applications of exosomal noncoding RNAs in cancer
Liu Qin-Wen,He Yan,Xu Wen Wen 생화학분자생물학회 2022 Experimental and molecular medicine Vol.54 No.-
Cancer is one of the most difficult diseases in human society. Therefore, it is urgent for us to understand its pathogenesis and improve the cure rate. Exosomes are nanoscale membrane vesicles formed by a variety of cells through endocytosis. As a new means of intercellular information exchange, exosomes have attracted much attention. Noncoding RNAs exist in various cell compartments and participate in a variety of cellular reactions; in particular, they can be detected in exosomes bound to lipoproteins and free circulating molecules. Increasing evidence has suggested the potential roles of exosomal noncoding RNAs in the progression of tumors. Herein, we present a comprehensive update on the biological functions of exosomal noncoding RNAs in the development of cancer. Specifically, we mainly focus on the effects of exosomal noncoding RNAs, including microRNAs, circular RNAs, long noncoding RNAs, small nuclear RNAs, and small nucleolar RNAs, on tumor growth, metastasis, angiogenesis, and chemoresistance. Moreover, we outline the current clinical implications concerning exosomal noncoding RNAs in cancer treatment.

For the problem that the use effect of food processing information system is poor due to absence of knowledge acquisition measures and knowledge self-updating function, a knowledge acquisition approach based on rough set is put forward. First, the approach establishes a set of predicted samples for the relationship between food processing parameters and product quality; then uses the discretization of continuous attribute, attribute reduction and rule extraction algorithm of rough set to acquire automatically predicted knowledge from a large number of predicted sample sets, and then saves the predicted knowledge in the knowledge base of expert system; finally, realizes the extraction of knowledge of food processing process based on the inference engine, which greatly enhances the effectiveness and practicality of the acquired knowledge in online aided decision system of the food processing quality and safety.

Objective : Shunt infection is a common complication while treating hydrocephalus. The antibiotic-impregnated shunt catheter (AISC) was designed to reduce shunt infection rate. A meta-analysis was conducted to study the effectiveness of AISCs in reduction of shunt infection in terms of age, follow-up time and high-risk patient population. Methods : This study reviewed literature from three databases including PubMed, EMBASE, and Cochrane Library (from 2000 to March 2019). Clinical studies from controlled trials for shunt operation were included in this analysis. A subgroup analysis was performed based on the patient's age, follow-up time and high-risk population. The fixed effect in RevMan 5.3 software (Cochrane Collaboration) was used for this meta-analysis. Results : This study included 19 controlled clinical trials including 10105 operations. The analysis demonstrated that AISC could reduce the infection rate in shunt surgery compared to standard shunt catheter (non-AISC) from 8.13% to 4.09% (odds ratio [OR], 0.48; 95% confidence interval [CI], 0.40-0.58; p=0.01; I2=46%). Subgroup analysis of different age groups showed that AISC had significant antimicrobial effects in all three groups (adult, infant, and adolescent). Follow-up time analysis showed that AISC was effective in preventing early shunt infections (within 6 months after implant). AISC is more effective in high-risk population (OR, 0.24;95% CI, 0.14-0.40; p=0.60; I2=0%) than in general patient population. Conclusion : The results of meta-analysis indicated that AISC is an effective method for reducing shunt infection. We recommend that AISC should be considered for use in infants and high-risk groups. For adult patients, the choice for AISC could be determined based on the treatment cost.
