Dragon Boat

Dragon boat is an excellent traditional national sport in China, with excellent fitness results. Based on the country’s strong support for traditional national sports, the dragon boat has developed into a traditional national sport with specific influence and popularity among the masses. Eggshell membrane (ESM) has the effect of relieving arthritis, joint pain, and joint stiffness. The supplementary ESM’s preventive effect on sports injuries has attracted people’s attention. Based on this, this article builds a sports injury prediction model under artificial intelligence and big data monitoring to accurately predict the injuries suffered by athletes, provide help to reduce athletes’ injuries during training, and promote the development of dragon boat sports. This article selects 20 members of a dragon boat team from a university and randomly divides them into a control group (supplement of equal amounts of whey protein), a normal group, an ESM low-dose group (26 mg/kg bw/d), and an ESM high-dose group (52 mg/kg bw/d), with 5 people in each group. The subjects were subjected to downhill exercise and immune stimulation experiments. Among them, the subjects in the control group performed downhill exercise for 12 hours, and they were tested for lactic acid (LAC), lactate dehydrogenase (LDH), urea, malondialdehyde (MDA), hemoglobin (Hb), blood creatinine (CRE), and other related physical and chemical indicators. The other three groups of subjects did not take low-dose and high-dose ESM for 7 consecutive days and were injected with lipopolysaccharide on the 8th day for immune stimulation and tested for interferon (IFN-γ), tumor necrosis factor (TNF-α), interleukins (IL-1β, IL-6, and IL-10), and other related cytokines. The results show that oral egg membrane protein (ESM) can reduce subjects’ serum LAC, LDH, urea, MDA, Hb, and CRE concentration. In addition, the ESM can reduce the expression of proinflammatory factors IL-1β and TNF-α, while increasing the expression of anti-inflammatory factor IL-10, which provides clinical data for the clinical use of ESM as a supplement for sports injury or for relieving arthritis symptoms. The study shows that egg membrane protein has a protective effect against sports injury and may be regulated by inflammatory factors.

Hypoxia Reoxygenation

Tumor necrosis factor-alpha (TNF-α) has an important role in hypoxia/reoxygenation (H/R)-induced intestinal damage. It was shown that blocking TNF-α with infliximab has beneficial effects on experimental necrotizing enterocolitis and hypoxic intestinal injury. However, there is no data about the effect of adalimumab on H/R-induced intestinal damage. Therefore, we aimed to determine potential dose-dependent benefits of adalimumab in such damage in neonatal rats. Wistar albino rat pups were assigned to one of the four groups: control group, hypoxia group, low-dose adalimumab (5 mg/kg/day) treated group (LDAT), and high-dose adalimumab (50 mg/kg/day) treated group (HDAT). On the fourth day of the experiment, all rats except for the control group were exposed to H/R followed by euthanasia. Malondialdehyde (MDA), myeloperoxidase (MPO), TNF-α, total antioxidant capacity (TAC), and total oxidant capacity (TOC) were measured in intestinal tissue. TAC and TOC values were used to calculate the oxidative stress index (OSI). Histopathological injury scores (HIS) were also evaluated in the tissue samples. MDA levels were significantly lower in the LDAT and HDAT groups (p < 0.001). TNF-α levels were significantly lower in the LDAT group (p < 0.001). OSI was significantly higher in the H/R group than in the control and LDAT groups (p < 0.001). Mean HIS values in the LDAT group were significantly lower than those in the H/R and HDAT groups (p < 0.001). This experimental study showed that low-dose adalimumab appears to have a beneficial effect on intestinal injury induced with H/R in neonatal rats.

The aim of this study was to investigate the alleviating effect of Lactobacillus paracasei subsp. paracasei LC-01 (LC-01) on the murine model of colitis induced by dextran sulphate sodium (DSS). 50 pathogen-free, 6-week-old male BALB/c mice were divided randomly into 5 groups, including a control group and four DSS-LC-01-treated groups (DSS, DSS-106, DSS-108, and DSS-1010 with 0, 1×106, 1×108 and 1×1010 cfu/ml LC-01, respectively). To test the effectiveness of LC-01 as a prophylactic it was administered for 7 days before the onset of the disease in DSS-LC-01-treated mice. After 7 days, colitis was induced by administration of 2.5% (w/v) DSS in drinking water for a further 7 days. The disease activity index (DAI), histological score, myeloperoxidase (MPO) activity and the level of the pro-inflammatory cytokines interleukin-1β (IL-1β) and tumour necrosis factor α (TNF-α) were measured. DAI, histological scores and MPO activity of mice treated with a medium or high dose of LC-01 were significantly lower compared to a low-dose of LC-01 and DSS treatment alone (P<0.05). Colon length shortening could be prevented with increasing dose of LC-01. In addition, the levels of IL-1β and TNF-α were suppressed significantly by treatment with a medium and high dose of LC-01. However, no significant difference in the indices mentioned above were observed between a low dose of LC-01 and treatment with DSS alone (P≯0.05). An appropriate dose of LC-01 can prevent intestinal damage in mice with DSS-induced colitis. The expression of inflammatory cytokines related to pathogenesis of DSS-induced colitis decreased following treatment with LC-01.

Exposure to drugs and toxic chemicals, during late pregnancy, is a common occurrence in childbearing women. Some studies have reported that more than 90% of pregnant women use at least 1 prescription; of this, 60% used more than one. Another study indicated that 80% of the consumed drugs were not prescribed, and of this figure, 95% were “over-the-counter” drugs. Acetaminophen, the safest of all over-the-counter drugs, has been reported to induce fetal liver necrosis in man and animals and to have abortifacient and embryocidal action in mice. This study examines the degree to which acetaminophen affects the neonatal liver and kidney, when a fatty diet is simultaneously fed to the mother during late pregnancy.Timed Swiss Webster female mice were gavaged during late pregnancy (days 16-19) with fat suspended acetaminophen at a high dose, HD = 84.50 mg/kg, and a low dose, LD = 42.25 mg/kg; a control group received fat alone.

Background Evidence begin to accumulate that high-dose sub-lingual immunotherapy (SLIT) is as effective as subcutaneousimmunotherapy (SIT) in the treatment of childhood asthma.Since the capacity of sublingual area is similar whether the doseis high or low, the efficacy of low dose may be important to bestudied.Objective To investigate the efficacy of low-dose sublingual im-munotherapy in the treatment of childhood asthma.Methods Parents signed informed consent prior to enrollment,after having received information about the study. Patients weremoderate asthma aged 6-14 years with disease onset of lessthan 2 years before the commencement of the study and peakexpiratory flow rate (PEFR) variability of more than 15%. Pa-tients were randomly allocated into group A, B, and C whoreceived subcutaneous immunotherapy, low-dose sublingualimmunotherapy, and conventional asthma therapy, respectively.Randomization was stratified into two strata according to agei.e., 6-11 years or 11-14 years. Patients of each stratum wererandomized in block of three for each group. At the end of threemonths, lung function tests were repeated. The primary outcomewas PEFR variability at the end of the study. The study wasapproved by the Ethics Committee of Soetomo HospitalSurabaya.Results Distribution of variants as represented by sex, age,eosinophil count, and total IgE concentration were normal inthe three groups. PEFR variability decreased significantly from16.97+0.81 to 8.50+5.08 and 17.0+0.87 to 8.40+4.72 in groupreceiving SIT and SLIT, respectively (p<0.05), but decreasednot significantly from 17.00+0.83 to 10.82+0.5.41 in control group(p>0.05).Conclusion Low-dose SLIT is as efficacious as SIT in the treat-ment of moderate asthma in children

(1) Background: The endothelial glycocalyx is a primary target during the early phase of sepsis. We previously reported a newly developed recombinant non-fucosylated antithrombin has protective effects in vitro. We further evaluated the effects of this recombinant antithrombin on the glycocalyx damage in an animal model of sepsis. (2) Methods: Following endotoxin injection, in Wistar rats, circulating levels of hyaluronan, syndecan-1 and other biomarkers were evaluated in low-dose or high-dose recombinant antithrombin-treated animals and a control group (n = 7 per group). Leukocyte adhesion and blood flow were evaluated with intravital microscopy. The glycocalyx was also examined using side-stream dark-field imaging. (3) Results: The activation of coagulation was inhibited by recombinant antithrombin, leukocyte adhesion was significantly decreased, and flow was better maintained in the high-dose group (both p < 0.05). Circulating levels of syndecan-1 (p < 0.01, high-dose group) and hyaluronan (p < 0.05, low-dose group; p < 0.01, high-dose group) were significantly reduced by recombinant antithrombin treatment. Increases in lactate and decreases in albumin levels were significantly attenuated in the high-dose group (p < 0.05, respectively). The glycocalyx thickness was reduced over time in control animals, but the derangement was attenuated and microvascular perfusion was better maintained in the high-dose group recombinant antithrombin group (p < 0.05). (4) Conclusions: Recombinant antithrombin maintained vascular integrity and the microcirculation by preserving the glycocalyx in this sepsis model, effects that were more prominent with high-dose therapy.

Background and Aim: Thyroid is one of the endocrine glands, (T3 and T4) play a significant role in the development of prenatal brain and the following stages. The study aimed to evaluate the effect of hypothyroidism on the amount of expression of NT4, NT3, nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in brain of one-day rat neonates with hypothyroidism.Materials and Methods: In total, 25 mature mice of Albino NMRI race were selected after mating, divided into three group, control, as well as low-dose and high-dose intervention groups. Samples of the control group received pure water during pregnancy, whereas subjects of the intervention group with low and high doses of the medication were administered with 20 mg and 100 mg methimazole powder (dissolved in 100 cc water), respectively. After child delivery, blood samples were obtained from mother mice to determine the level of T3 and T4 in blood serum. Following that, the brain of one-day mice were removed by surgery and assessed to determine the amount of expression of NT4, NT3, NGF and BDNF using the complete kit of RT-PCR.Results: Levels of T4 and T3 in the control group were 28 ug/dl and 1.59 ug/dl, respectively. In the low-dose intervention group, the amounts of the mentioned hormones were 8 ug/dl and 0.85 ug/dl, significantly, indicating a significant reduction in the expression of NT4, NT3, NGF and BDNF genes, compared to the control group. Moreover, T4 and T3 were 6 ug/dl and 0.79 ug/dl in the high-dose group, respectively, conveying a significant decrease in the expression of NT4, NT3, NGF and BDNF genes, compared to the control group (P<0.05).

SynopsisIn 17 benzodiazepine (BDZ) dependent in-patients a CT scan was performed before initiation of withdrawal therapy. The evaluation of the ventricular to brain ratio (VBR) by standardized and computerized measurements revealed significantly higher mean VBRs for both high-and low-dose BDZ-dependent patients compared to the mean VBR of an age- and sex-matched control group. In addition, the mean VBR of high-dose BDZ-dependent patients (N = 8) was significantly higher than the mean VBR of low-dose BDZ-dependent patients (N = 9). This difference could not be accounted for by the age of the patients or duration of BDZ-dependency and, therefore, suggests a dose-dependent effect of BDZs on the enlargement of internal CSF-spaces. On the other hand, higher values for the width of external CSF-spaces were found to be related to increasing age of the patients and duration of BDZ-dependency.

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

Diminished ovarian reserve (DOR) refers to a decrease in the number and quality of oocytes. Western treatment of DOR does not improve the ovarian reserve fundamentally, and the effect is limited. Gengnianchun recipe (GNC) is a traditional Chinese medicine formula originally applied to treat menopausal syndrome but is also found to be effective in treating clinical DOR patients. Here we aim to examine the effect of GNC in a DOR rat model induced by 4-vinylcyclohexene diepoxide (VCD), a chemical that selectively destroys ovarian small preantral follicles, and further investigate the possible mechanisms. Female SD rats were randomly divided into four groups: control group (C), model group (M), high-dose GNC group (H), and low-dose GNC group (L). Rats in M, H, and L were administered with VCD and normal saline, high-dose GNC, and low-dose GNC separately. Rat ovaries were harvested either to conduct HE staining for follicle count, immunohistochemistry, or western blot. We found that high dose of GNC significantly increased the ovarian index and sustained the number of primordial follicles and primary follicles in VCD treated rats. Moreover, high dose of GNC significantly increased the ovarian protein expression of mouse vasa homologue (MVH), anti-Müllerian hormone (AMH), follicle-stimulating hormone receptor (FSHR), and estrogen receptor β (ERβ) compared with that in the model group. Besides, high-dose GNC significantly increased ovarian AKT phosphorylation and the expression of downstream forkhead box O3 (FOXO3a). Proapoptosis proteins of Bax, cleaved caspase-3, and poly ADP-ribose polymerase (PARP) were significantly decreased after high-dose GNC treatment compared with those in the model group. Taken together, these findings suggest that high-dose GNC could protect ovarian reserve against VCD-induced toxicity via the activation of the AKT signaling pathway and reduced cell apoptosis in SD Rats. This effect could either be induced by the increased FSHR signaling or by the nontranscriptional activation of ERβ, which requires further investigation.
