Taurine, derived from the metabolism of methionine and cysteine, is a strong acidic sulfonic acid zwitterionic β-amino acid that contains an acidic sulfonic group, an alkaline amino group, and two carbons in between. It exhibits strong water solubility and poor lipophilicity within the physiological pH range. Due to the absence of carboxyl groups, it does not participate in protein synthesis and is a semi essential amino acid. The physicochemical properties of taurine make it an ideal regulator for various basic physiological processes, with various functions such as maintaining homeostasis, bile acid binding, anti⁃oxidant stress, anti-inflammatory, protecting cardiovascular, protecting central nervous system, and participating in immune regulation. In recent years, with the promotion of low protein diets and the popularization of intensive factory production, the disease resistance of livestock and poultry has been greatly challenged. It is necessary to add taurine reasonably to the diet. Therefore, the research progress of taurine in the fields of animal physiology and animal nutrition were introduced in this article, aiming to provide reference for the majority of livestock practitioners.

This experiment was conducted to study the effects of compound Chinese herbal medicine additives on the production performance, milk quality, and serum immune indicators of lactating cows. Sixty 24-month-old Chinese Holstein dairy cows were randomly divided into 4 groups with 3 replicates in each group and 5 cows in each replicate. Others in the control group were fed a basal diet, and the others in the three experimental groups were fed the basal diet supplemented with 100, 200 g/d and 400 g/d compound Chinese herbal additives, respectively. The experiment lasted for 30 days. The results showed as follows: Compared with the control group, dietary supplementation of 200 g/d and 400 g/d compound Chinese herbal additives significantly increased the average daily milk yield of lactating cows (P<0.05), and significantly decreased the ratio of feed to milk of lactating cows (P<0.05); dietary supplementation of 200 g/d and 400 g/d compound Chinese herbal medicine additive significantly increased the milk protein level of lactating cows (P<0.05), and significantly decreased the somatic cell count of milk (P<0.05). Dietary 200 g/d and 400 g/d compound Chinese herbal medicine additive significantly increased the contents of immunoglobulin A (IgA), immunoglobulin G (IgG) and interleukin-2 (IL-2) in serum of lactating dairy cows (P<0.05). The content of interleukin-1β (IL-1β) in serum of lactating cows was significantly decreased (P<0.05). In conclusion, dietary supplementation of compound Chinese herbal medicine additives can improve the production performance, dairy quality and immune function of lactating dairy cows. Considering the economic cost, the recommended dosage of compound Chinese herbal medicine additives is 200 g/d. [ABSTRACT FROM AUTHOR]

The experiment was to explore the effect of jasmine slag on apparent digestibility of nutrients, rumen fermentation and rumen bacterial flora of goats. Twenty-four healthy four-month-old Nubian rams with similar body weight and no disease were randomly divided into two groups, with 12 replicates in each group and one ram in each replicate. Rams in control group were fed with a basal diet, and those in experimental group were fed with a basal diet supplemented with 100 g/kg jasmine slag to make a full-price granular diet. The pre-test lasted for 7 d and the formal experiment lasted for 45 d. The results showed that compared with control group, the apparent digestibility of crude protein in experimental group was extremely decreased (P<0.01), and the apparent digestibility of acid detergent fiber was extremely increased (P<0.01). The results of microbial sequencing showed that Firmicutes and Bacteroides were the dominant phyla between control group and experimental group at phyla level. At genus level, the relative abundance of Succinobacteria, Prevotella_UCG_001 and Christiania_R_7 groups in experimental group was significantly higher than that in control group (P<0.05), while the relative abundance of unclassified Bacteroides in experimental group was significantly lower than that in control group (P<0.05). The experiment indicates that the addition of jasmine slag to the diet can increase the relative abundance of fiber degrading bacteria and improve the digestion of fiber in goats.

In this paper, the polarization luminescence characteristics of the near-band-edge peak and Fe3 + related emission peaks(4T1 (G)-6A1 (S)) of the non-polar surfaces including a-plane {11 20} and m-plane {1 100} of Fe-doped GaN crystal were studied by low-temperature photoluminescence(PL) measurement. The results show that the optical anisotropy of a-plane and m-plane are similar. When the linearly polarized electric-field vector E is parallel to the c-direction [0001] (E//c), the intensity of GaN near-band-edge peak is the lowest, and the intensity of Fe3+ zero-phonon line (1.299 eV) is the strongest. The degree of polarization of Fe3+ zero-phonon line is greater than that of near-band-edge peak. The degree of polarization of near-band-edge peak of a-plane is 26%, while the degree of polarization of Fe3+ zero-phonon line reaches up to 55% and 58% of a-plane and m-plane GaN, respectively. The polarization characteristics of Fe3+ fine peak and the additional lines are further measured at 5 K. The results show that, except for one weak peak, other peaks are consistent with the polarization characteristics of Fe3+ zero-phonon line. This study is helpful to expand the application of Fe-doped GaN crystal in the field of novel optical and electrical devices. [ABSTRACT FROM AUTHOR]

To explore the cumulative deformation characteristics of pile group foundation under two-way cyclic coad, based on an in, service offshore wind power project in the South China Sea, a refined three-dimensional finite element model was established using ABAQUS, and an improved soil stiffness attenuation model was introduced and embedded into the subrsubrine USDFLD to realize the simulation of seabed soil stiffness attenuation under two-way cyclic coad. At the same time, two-way cyclic sinusoidal load was introduced and subroutine DLOAD was used to realize the composite loading of the model. Based on the numerical results, the evolution lateral cumulative displacement and pile bending moment of pile group foundation under two-way cyclic coad with different amplitudes and cycles was analyzed. The results show as follows. Under two-way cyclic load, the horizontal displacement and bending moment of each pile surface increase with the increase of load cycle times, showing obvious cumulative effect. Under two-way cyclic load, the lateral cumulative displacement and he bending moment of piles in the front row is the largest, followed by piles in the middle row and piles in the back row. When horizontal (vertical) at constant load, the pile foundation with lateral deformation horizontal (vertical) increases with increasing load, and the larger the horizontal (vertical) load is, the more severe the lateral deformation of pile foundation increases, but at the same time, there is a minimum horizontal cyclic load, which leads to the accumulation of lateral displacement of each pile under bidirectional cyclic load is not obvious, and is close to one-way horizontal cyclic loading.

BACKGROUND: Methods of blood transfusions and regular iron removal have been gradually introduced in thalassemia patients since the 1980s. However, this method is limited by the need of a large amount of social resources to be widely used. With the continuous progress of stem cell research in recent years, there is a new hope of using stem cell technology to treat thalassemia. OBJECTIVE: To review the therapeutic effect of stem cell therapy on thalassemia. METHODS: The first author searched relevant articles with PubMed database and CNKI (from 1989 to 2017) using the key words of “thalassemia, hematopoietic cell transplantation, therapy, stem cell” in English and “thalassemia, stem cell therapy, transplantation” in Chinese, respectively. After initial screening, 51 articles were retained. RESULTS AND CONCLUSION: Prior to the use of stem cells to treat patients with thalassemia, a reasonable drug conditioning program and a proper donor source can increase the survival rate, and reduce the incidence of rejection and graft-versus-host disease after transplantation. At the same time, the age of recipients and the level of risk assessment are important reference factors in the transplantation process, which directly affect the effect of stem cell transplantation. In addition, choosing the appropriate type of stem cells, improving the transplantation method, and optimizing drug conditioning can reduce complications and risks of transplantation, and improve the quality of life of thalassemia patients.
