The primary objective of this study is to assess the impact of climate change on the current and future spatial distribution of areas suitable for the growth of Senegalia senegal, a forest species of significant agro-ecological and socio-economic importance. To achieve this objective, the MaxEnt (Maximum Entropy) model was utilized, incorporating species presence points alongside bioclimatic variables. To project future distributions, three climatic models-CCCMA, HadCM3, and CSIRO were employed under the A2 scenario to predict the species’ distribution by the year 2050. Currently, habitats highly favorable for the conservation of the species are situated in the Sahelo-Sudanian and Sudanian zones, accounting for 6.81% of the national territory. All models forecast a substantial increase in habitats highly favorable for the future conservation of S. senegal, with a total expected growth of 448.9%. Conversely, moderately favorable and unfavorable habitats are predicted to decrease by 106.26% and 78.59%, respectively. These findings provide crucial data for the long-term conservation strategy of this species, which holds significant ecological and agronomic potential for the Sahelian region.

AIM: To look at the relationship between eosinophilic oesophagitis(EO) and food bolus impaction in adults. METHODS: We retrospectively analysed medical records of 100 consecutive patients who presented to our hospital with oesophageal food bolus obstruction(FBO) between 2012 and 2014. In this cohort, 96 were adults(64% male), and 4 paediatric patients were excluded from the analysis as our centre did not have paediatric gastroenterologists. Eighty-five adult patients underwent emergency gastroscopy. The food bolus was either advanced into the stomach using the push technique or retrieved using a standard retrieval net. Biopsies were obtained in 51 patients from the proximal and distal parts of the oesophagus at initial gastroscopy. All biopsy specimens were assessed and reviewed by dedicated gastrointestinal pathologists at the Department of Pathology, University Hospital Geelong. The diagnosis of EO was defined and established by the presence of the following histological features:(1) peak eosinophil counts > 20/hpf;(2) eosinophil microabscess;(3) superficial layering of eosinophils;(4) extracellular eosinophil granules;(5) basal cell hyperplasia;(6) dilated intercellular spaces; and(7) subepithelial or lamina propria fibrosis. The histology results of the biopsy specimens were accessed from the pathology database of the hospital and recorded for analysis. RESULTS: Our cohort had a median age of 60. Seventeen/51(33%) patients had evidence of EO on biopsy findings. The majority of patients with EO were male(71%). Classical endoscopic features of oesophageal rings, furrows or white plaques and exudates werefound in 59% of patients with EO. Previous episodes of FBO were present in 12/17 patients and 41% had a history of eczema, hay fever or asthma. Reflux oesophagitis and benign strictures were found in 20/34 patients who did not have biopsies. CONCLUSION: EO is present in approximately one third of patients who are admitted with FBO. Biopsies should be performed rout

银杏萜内酯主要包括银杏内酯A、B、C和白果内酯.银杏内酯B是一种很有应用前景的特异性血小板激活因子(PAF)受体拮抗剂,其专一性高,而银杏内酯A也是一种重要的昆虫拒食素,白果内酯对老年痴呆症和神经系统疾病具有一定疗效[1].目前,银杏萜内酯对心脑血管及外周血管疾病的有效疗效已使他成为药品及保健食品的原料.但目前银杏叶仍是提取银杏萜内酯化合物的主要工业生产来源.银杏萜内酯的提取分离方法报道较多.由于银杏叶中这类化合物含量很低,且具有特定结构,因此,提取分离步骤烦琐,费时且得率低.目前,日本专利及欧洲报道一般采用有机溶剂多级萃取与硅胶吸附-洗脱或活性碳吸附-洗脱与醋酸铅沉淀法相结合的提取方法,但得率低,工艺繁锁[1,2].近几年国内银杏萜内酯的提取分离也有报道,主要采用高效液相制备色谱柱进行分离.

本文采用结构方程模型(SEM)方法,考察了泰国汉语学习者词汇知识、语素意识、词汇知识推理与汉语阅读理解的关系。结果发现:(1)词汇知识、词汇推理对阅读理解有直接贡献,且词汇知识的贡献大于词汇推理的贡献;语素意识对阅读理解贡献不显著。(2)语素意识对阅读理解存在以词汇知识和词汇推理为中介的间接效应,并且其间接效应大于其直接贡献。(3)词汇推理对阅读理解既存在直接贡献,又存在以词汇知识为中介的间接效应,但其直接贡献大于其间接效应。本文对结果进行了分析和讨论,并对对外汉语阅读教学提出了相应的建议。

为降低分布式存储系统中节点的存储量,构造了一类新(k+2,k)Hadamard MSR码.该码的每个编码矩阵皆对应于2个值,供其对角元素选取.在编码矩阵中,这2个值循环出现,且不同的矩阵,循环出现的周期不同.基于这一特性构造了节点的修复方案,将失效节点中的α个数据分成α/2组,每一组重建2个数据,其他k+1个节点为每一组各提供1个数据.证明了若新码编码矩阵的对角元素可取的2个值不相等,则可最优修复系统节点;若所有编码矩阵对角元素可取的2个值的和为同一不为0的值,则可最优修复第1个校验节点;若所有编码矩阵对角元素可取的2个值的逆的和为1,则可最优修复第2个校验节点.新码的节点存储量降低到了Hadamard MSR码的理论界,可最优修复任意系统节点和1个校验节点.

This study is to evaluate the clinical value of serum tumor supplied group of factors (TSGF) in diagnosis of canine cancer. 145 dogs with malignant tumors,32 benign diseases,34 dogs with non-tumor diseases,and 6 healthy dogs. Biochemical colorimetric assay were used to detect the serum TSGF level. Blood samples were collected at the time of initial diagnostic evaluation,before each chemotherapy session,and at follow-up visits. The serum TSGF level in dogs with malignant tumors,benign diseases,non-tumor diseases and healthy dog were 67. 3 ± 22. 1 U/mL,57. 3 ± 7. 58 U/mL,60. 2 ± 14. 2 U/mL and 54. 6 ± 3. 21 U/mL,the first group was statistically significant higher than the latter (P < 0. 05). 56. 6% malignant patients exceeded the upper limit of the normal reference range (61 U/mL). The samples were classified to groups according clinic stage. The TSGF level from malignant tumor groups were stage I 56. 8 ± 5. 93 U/mL. stage II 66. 7 ± 25. 7 U/mL,stage III 75. 6 ± 22. 7 U/mL and stage IV 73. 9 ± 29. 6 U/mL. Excluding stage I, the TSGF level of all stages are statistically significant higher than healthy group,respectively,the stage III was also statistically significant higher than stage I. Further follow-up study indicated that in entirely insect group,the TSGF level decreased after treatment and kept in low level. In the partly insect group,although the TSGF activity decreased in a short term after surgery,the TSGF level would increase again and kept in high level. From this fact we considered that TSGF level is expected to be a newly potential biomarker in screening neoplastic diseases in veterinary and a monitoring factor for predicting relapse.
