The Effect of Temperatures and Hosts on the Life Cycle of Spodoptera frugiperda (Lepidoptera: Noctuidae).

The interactions between ambient temperatures and host plants are central to the population dynamics of invasive animal species. Despite significant research into the effects of temperatures, the performance of invasive species is also influenced by host plants. The effects of different temperatures (20, 25, and 30 °C) and host plants (maize, sorghum, and coix seed) were tested on the mortality, development, reproduction, and population parameters of the fall armyworm (FAW), Spodoptera frugiperda (J E Smith) (Lepidoptera: Noctuidae), using an age-stage, two-sex life table. The results support the hypothesis that temperature and the species of the host plant significantly influences the performance of FAW. Feeding on maize at 30 °C resulted in a lower mortality rate, a shorter developmental time and longevity, a higher fecundity, intrinsic rate of natural increase (r), finite rate of increase (λ), and net reproductive rate (R0). However, at 20 °C, the host plant could eliminate temperature-mediated synergism in FAW performance, which did not reach statistical significance at 20 °C. Similar results induced by a relatively low temperature (20 °C) on different host plants were also found in the age-stage specific survival curves (sxj), fecundity (mx), maternity (lxmx), and reproductive value (vxj) curves of FAW. Consequently, we also need to pay more attention to FAW outbreaks on different host plants mediated by relatively low temperatures.

The Biocontrol Agent Pyemotes zhonghuajia Has the Highest Lethal Weight Ratio Compared with Its Prey and the Most Dramatic Body Weight Change during Pregnancy.

Pyemotes spp. are small, toxic, ectoparasitic mites that suppress Coleoptera, Hemiptera, and Lepidoptera plant pests. To explore their potential use as a biocontrol agent, we studied the reproductive development, paralytic process, time to lethality and mortality, and searching ability of Pyemotes zhonghuajia on different developmental stages of the oriental leafworm moth, Spodoptera litura. Pyemotes zhonghuajia gained 14,826 times its body weight during pregnancy. One single P. zhonghuajia female could rapidly kill one S. litura egg and first to third instar larvae, but not fourth to sixth instar larvae, prepupae, or pupae within 720 min. Pyemotes zhonghuajia could develop on eggs, first to sixth larvae, and pupae, but only produced offspring on the eggs and pupae. A single P. zhonghuajia female (an average weight of 23.81 ng) could paralyze and kill one S. litura third instar larvae (an average weight of 16.29 mg)-680,000 times its own weight. Mites significantly affected the hatch rate of S. litura eggs, which reduced with increasing mite densities on S. litura eggs. Releasing 50 or 100 P. zhonghuajia in a 2 cm searching range resulted in significantly higher mortality rates of S. litura first instar larvae within 48 h compared to second and third instar larvae in searching ranges of 4.5 and 7.5 cm within 24 h. To the best of our knowledge, this is the first study to reveal that P. zhonghuajia undergoes the greatest changes in weight during pregnancy of any adult female animal and has the highest lethal weight ratio of any biocontrol agent.

Incidence and Risk Factors of Alcohol Relapse after Liver Transplantation: Analysis of Pre-Transplant Abstinence and Psychosocial Features.

Alcohol-associated liver disease (ALD) is a common indication for liver transplantation (LT). Alcohol relapse after LT is associated with graft loss and worse prognosis. Over the past 20 years, the number and prevalence of living donor liver transplantations (LDLTs) have increased in Taiwan. The aims of this retrospective study are to analyze the incidence and risk factors of alcohol relapse after LT at a single center in Taiwan. A total of 98 patients with ALD who underwent LT from January 2012 to December 2018 were retrospectively evaluated by chart review. Pre-transplant characteristics as well as psychosocial and alcoholic history were used to test the possible associations among the risk factors studied and post-LT alcohol relapse. The incidence of post-LT alcohol relapse was 16.3%. The median duration of alcohol relapse after liver transplantation was 28.1 months (range: 1-89.4 months). The cumulative incidence was 12% and 19% at 1 year and 3 years after LT, respectively. The most powerful risk factors were a pre-LT abstinence period less than 6 months and younger age of starting alcohol. For predicting alcohol relapse, the accuracy rate of abstinence less than 6 months was up to 83.7%. In summary, pre-abstinence period plays a role in predicting post-LT alcohol relapse. Post-LT interventions should be considered specifically for the patients with short abstinence period. Long-term follow-up, patient-centered counseling, and enhancement of healthy lifestyle are suggested to prevent alcohol relapse.

Changes in serum FGF23 and Klotho levels and calcification scores of the abdominal aorta after parathyroidectomy for secondary hyperparathyroidism.

BACKGROUND: Changes of calcification scores of the abdominal aorta (CSAA) after total parathyroidectomy plus autotransplantation (TPX + AT) for symptomatic secondary hyperparathyroidism (SSHP) have never been reported. METHODS: Forty-nine patients who successfully underwent TPX + AT for SSHP were enrolled; 13 patients who had regular hemodialysis were enrolled as controls. Preoperatively, patients' age, gender, and duration of dialysis were recorded. Serum Ca, P, alkaline phosphatase (Alk-ptase), intact parathyroid hormone (iPTH), vitamin D, FGF23, and Klotho levels, and CSAA were measured. One year postoperatively, these data were measured again. In the control group, these data were recorded and measured before and one year later. RESULTS: Serum iPTH, Alk-ptase and FGF23 levels and CSAA of the study group were significantly higher than those of the control group. One year postoperatively, serum Ca, P, Alk-ptase, iPTH, and FGF23 levels and CSAA were significantly lower than those before surgery. Except for FGF23 levels, other items of the control group did not change significantly one year later, whereas the study group decreased CSAA more than the control group. CONCLUSION: One year postoperatively, CSAA decreased.

Structurally novel HDAC inhibitors based on the trans-β-arylacryl tetrahydroisoquinoline scaffold: the design, synthesis, and anti-cancer activity / 药学学报

In this study, a series of 18 histone deacetylases inhibitors (HDACis), derived from our in-house anti-cancer trans-β-arylacryl 1,2,3,4-tetrahydroisoquinoline-based scaffold, were designed, synthesized, and antitumor evaluated. HDAC1 inhibitory activity assay showed that compounds 13d-13f and 13m-13o demonstrated attractive enzymatic activity with IC50 at single-digit nanomolar or subnanomolar level.In addition, 13o exerted superior anti-proliferative activity (A549, IC50 = 0.89 μmol·L-1; HCT116, IC50 = 0.49 μmol·L-1) to that of vorinostat (SAHA).Besides,13e, with the most potent HDAC1 enzymatic activity (IC50 = 3.8 nmol·L-1), also displayed attractive cellular activity (A549, IC50 = 1.74 μmol·L-1; HCT116, IC50 = 2.43 μmol·L-1). The Western blot analysis illustrated that 13e treatment increased the acetylation of H3 and α-tubulin in a dose-dependent manner in A549 cells. In summary, 13e and 13o deserve further functional investigation.

Review of Zuoguiwan on Animal Models and Evaluation in Prevention and Treatment of Osteoporosis / 中国实验方剂学杂志

Zuoguiwan is a classic prescription for replenishing vital essence, tonifying kidney-Yin and nourishing the bone marrow. Zuoguiwan is one of the effective prescriptions for the prevention and treatment of osteoporosis (OP), which reflects the thought of Reinforcing Yang from Yin. The OP animal model simulates the pathological state and pathogenesis of OP in human, which is an important means to research the pathogenesis of OP and verify the effect of drugs. In this paper, two kinds of animal models and characteristics of Zuoguiwan in the prevention and treatment of osteoporosis were discussed in details. They are the primary osteoporosis animal models, including ovariectomized animal models and spontaneous elderly osteoporosis animal models, and the secondary osteoporosis models, including glucocorticoid-induced animal models, cyclophosphamide-induced animal models and subtotal nephrectomy animal models. The evaluation methods of Zuoguiwan in preventing and treating OP, including bone absorption markers and bone formation markers analyzed by enzyme-linked immunosorbent assay (ELISA), bone mineral density detected with dual-energy X-ray, the number of trabeculae, trabecular segregation, trabecular thickness, bone volume/tissue volume ratio and bone surface/volume ratio analyzed using micro-CT, bone pathological morphology observed by hematoxylin-eosin staining, bone biomechanical properties, such as the maximum load force based on biomechanical test. In order to provide scientific reference for the basic and clinical research of Zuoguiwan, the OP animal models and the pharmacodynamic effect of Zuoguiwan are evaluated comprehensively with five different and objective evaluation methods. However, the animal model of OP needs to be further optimized to highlight the pathogenesis and syndrome characteristics of Zuoguiwan in the treatment of OP.

Advance of exosomes in ischemic stroke / 中国病理生理杂志

Stroke is one of the major causes of death and disability in China and even worldwide.At present, treatment of stroke has been traditionally focused on reducing death of ischemic cells.However,clinical trials have shown that none of neuroprotective drugs tested achieve clinical benefit after acute stroke.Exosomes are 30~100 nm extracellular vesicles derived from cells with cell membrane structure.Many studies suggest exosomes play essential roles in intercellular communication by transferring their cargo between source and target cells in brain.Emerging data show that exsomes also make a contribution to brain recovery via regulating highly interactive process pathway after stroke.Here,we review these advances and highlight the potential therapeutic functions of exosomes in brain remodeling after stroke.

A probability model for analyzing speckles in intravascular ultrasound images to facilitate image segmentation / 南方医科大学学报

Ultrasonic image speckles result from the interference of the reflected signals by the scatters in the detected tissue. The physical characteristics of the speckles are closely correlated with the structures of the biological tissues, and the probability distribution of these speckles differs across different tissues. Based on the probability characteristics of intravascular ultrasound (IVUS) speckles, a Gamma mixture model and Gaussian mixture model are proposed to describe the calcified plaque, soft plaque and normal vascular regions on IVUS images. Using KS test, KL divergence and correlation coefficient analysis, we found that the probability distributions of the speckles generated by calcified plaques and normal blood vessels were better described by the Gaussian mixture model, while the speckles caused by soft plaques were described better by the Gamma mixture model. Based on this finding, we propose a probability mixture model combining neighborhood information for plaque segmentation on IVUS images. Compared with the existing probabilistic mixture model, the segmentation accuracy was greatly improved with a reduced noise.

Potent rapid antidepressant effects of effective fraction of GJ-PE and up-regulation of BDNF and TrkB / 中国药理学通报

Aim To identify whether the petroleum e-ther fraction of Gardenia jasminoides Ellis ( GJ-PE ) could effetive exhibit a rapid antidepressant effect and also to investigate the biological mechanism. Methods Tail suspension test ( TST ) , forced swimming test ( FST ) and novelty suppressed-feeding ( NSF ) were used to screen the rapid antidepressant potential of ef-fective fractions of GJ-PE in KM mice at 24 h post a single administration. Tail suspension test ( TST) was also used at 30 min and forced swimming test ( FST ) was used at 2 h to test the initial onset time of effective fractions of GJ-PE in KM mice. Western blot was per-formed to examine the expression of BDNF and p-eEF2 in hippocampus of KM mice at 2 h and 24 h. Results An acute administration of GJ-PE1 decreased the im-mobility time of KM mice in FST at 2 h and 24 h and decreased the latency time in NSF at 24 h. GJ-PE3 de-creased the latency time in NSF at 24 h. GJ-PE4 in-creased the unit food consumption in NSF at 24 h. At 2 h post a single GJ-PE1 treatment, the expression of BDNF was significantly up-regulated while the expres-sion of p-eEF2 was significantly down-regulated. At 24 h post a single GJ-PE1 treatment, the expression of BDNF was significantly down-regulated while p-eEF2 expression was significantly up-regulated. Conclusion GJ-PE1 has the most significant rapid antidepressant potential among the four fractions of GJ-PE. The effec-tive time of GJ-PE1 is 2 h after drug treatment. The mechanism of the rapid antidepressant effect of GJ-PE1 at 2 h is related to the up-regulation of BDNF and down-regulation of p-eEF2 . GJ-PE3 and GJ-PE4 also have some features of rapid antidepressants. GJ-PE2 doesn′t have the rapid antidepressant potential.
