Background: The Coronavirus disease 2019 (COVID-19) is a respiratory infectious disease, also named Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which can cause various systemic manifestations that pose a threat to human life. Oral lesions in patients with COVID-19 may appear during or after the illness and may or may not be a consequence of the viral infection. Objective: In this case series we compare the oral manifestations in hospitalized COVID-19 positive patients and COVID-19 negative dental outpatients. Methods: 60 hospitalized COVID-19 patients and 41 control patients, were examined for oral signs and symptoms. The controls were dental patients who visited the hospital for dental care without complaining of any problems related to the oral cavity itself. Results: We have observed a strong association between certain clinical findings and COVID-19, including alterations in taste (ageusia, dysgeusia, and hypogeusia), anosmia, hairy tongue, tongue imprints, red tongue, erythematous candidiasis, pseudomembranous candidiasis, and exfoliative cheilitis. A trend but not statistically significant association at the level of 5% was also noted for colored tongue, linea alba, and pale mucosa. On the contrary, fissured tongue and oral mucosa pigmentation were more frequent in the controls, statistically significant at the level of 5%. Conclusion: COVID-19 has been found to impact the oral cavity, resulting in various oral lesions that can be attributed to either the direct action of the virus or the patient’s immune response.

In Central African Republic, edible caterpillars of Imbrasia gender are income of rural populations, present an opportunity to improve food security and belonging to the category of Non-wood forest products. The goal of this study is to document the ecology of caterpillars of genre Imbrasia in relation to its host plants in Boukoko. The questionnaire was addressed to the actors of the collection and consumption of caterpillars in this Commune, to their local knowledge concerning this food resource as well as the plants of their locality on which caterpillars are collected. The survey took place in September to October 2022 and as a general rule, the 120 respondents were elderly people whose age range varied from 35 to 70 years old. Plant samples are collected in their natural environment. Based on local names;herbaria are mounted, plants photographed and samples collected. The types of edible caterpillars have been inventoried in the field in collaboration with the local populations who consume them. Based on local names, the caterpillars are captured manually from morphological traits and then stored in bottles containing 70% ethanol. The specimens were identified. The data was entered into the Excel spreadsheet which also made it possible to produce histograms with the frequencies of the plant species most valued by the different caterpillars. A Principal Component Analysis (PCA) was then performed using R software to highlight the correlation between caterpillars and host plants. The main economic importance trees hosting edible caterpillars of Imbrasia gender in Boukoko region are: Entandrophragma cylindricum, Pentaclethra macrophylla, Maesopsis eminii, Albizia ferruginea, Macaranga spinosa, Amphimas ferrugineus, Pentaclethra macrophylla, Racosperma auriculiforme, Eribroma oblonga. The Principal Component Analysis (PCA) carried out to assess the variability between the different species of caterpillars according to their host plants shows that the first two axes

With increasing life expectancy， neurodegenerative diseases have become one of the leading causes of ill-health in the elderly. Preventive strategies include following healthy diets， such as the Mediterranean diet， which is particularly rich in polyphenols， bioactive compounds with neuroprotective properties. The aim of this study was to assess the association of microbial phenolic metabolites (MPM) with cognition. This cross-sectional analysis was performed with 200 participants of the PREDIMED trial (Barcelona-Clinic recruitment center). A novel method based on liquid chromatography coupled to mass spectrometry was used to identify urinary MPM (protocatechuic acid， enterodiol glucuronide， enterolactone glucuronide， urolithin B glucuronide， and vanillic acid glucuronide)， and cognitive function was evaluated with neuropsychological tests. Multivariable-adjusted ordinary least squares regression was used to assess the associations between cognitive function and MPM， and a score was calculated as the weighted sum of MPM. A higher MPM score was associated with better frontal lobe function. Among individual metabolites， vanillic acid glucuronide was correlated with frontal cognitive performance. Participants with higher concentrations of vanillic acid glucuronide and urolithin B glucuronide obtained better scores in the Color Trail Test part 2. A higher score for urinary multi-MPM was associated with better frontal cognitive performance in an older Mediterranean population.

阿尔泰山南坡受到西风急流、北冰洋冷湿气流、蒙古-西伯利亚高压和亚洲低压共同影响,形成了当地特有的气候模式;同时,阿尔泰山地区是欧亚沟通的枢纽地带,气候变化对周边人类生产生活以及生态系统影响显著。因此有必要了解阿尔泰山周边气候变化长期历史,识别气候变化特征,总结规律以应对未来气候变化带来的灾害。本研究利用相关分析发现阿尔泰山南坡西伯利亚落叶松树轮宽度年表与夏季(6~7月)温度呈显著关系(r=0.626,n=58,p<0.001),进而建立一阶线性回归模型方程定量重建了阿尔泰山南坡过去304年(1715~2018年)夏季温度变化。统计结果显示重建序列稳定可靠,并有能力代表大范围的温度变化特征。重建存在5个暖期(1740~1767年、1775~1793年、1837~1847年、1898~1909年、1990~2018年)和5个冷期(1715~1727年、1807~1828年、1848~1858年、1876~1897年、1927~1940年)。虽然自1990年来温度持续上升(1990~2018年温度距平0.33℃),但并未超过1740~1767年的温度(温度距平0.49℃)。结合周边降水重建序列,发现研究区域在过去3个多世纪表现出夏季水热同步的配置模式,即暖湿/冷干模态占主导地位。

“知/智”二字的本字是甲骨文中已有的从“■”(矢)、“口”的“■”字,可以直接隶定为“知”。该字在甲骨文中用作动词,在“知乞骨”句中表达占卜之前加工卜甲、卜骨,或解释为钻孔加工。在殷商的信仰中,“知乞骨”绝对是一件神秘之事:神灵认可这些卜骨,并同意只有在经由这些卜骨沟通时,巫师才可以使用这些卜骨。由此,我们或可以推论,“知”字最早的意义,是在具体形容加工卜骨的同时,也表达甲骨能获得灵验之图谋,可用作神秘沟通之媒介。通过“知”这种神秘的加工行为,一般的龟甲和牛骨成为可知天意的卜甲、卜骨。在青铜器铭文上也出现“知/智”字,用来表达与崇高界的神秘沟通。战国楚简和传世文献也表达“知/智”含有神秘知通之意。所以,通过殷商以后“知/智”字的用义,可以看出该字以甲骨文“知”字为源头。从西周晚期以来,“知”字有“知”“■”“■”“■”等数种写法,这些字形的字义都相同,所以它们都是“知”字的异构,在意义方面与神秘、明智等本义仍保留有一定的关系。

通过室内模型试验，以普通尿素（U）、腐植酸包膜尿素（U-HA）和脲酶抑制剂N-（正丁基）硫磷三酰胺处理尿素（U-UI）为研究对象，研究了3种尿素肥料对土壤氮素转化过程的影响。更正研究了尿素肥料对土壤化学（水浸提N-NH4和N-NO3含量）和微生物特性（N2O实际和潜在排放速率、基础呼吸和底物诱导的呼吸、微生物生物量碳、乙烯排放速率）的影响，旨在验证：（i）腐植酸包膜尿素是否具有减少土壤氮素损失的能力；（ii）与合成脲酶抑制剂相比，它是如何影响土壤生物活性的。结果表明，U-HA在减少土壤氮素损失方面具有与U相当的优势，使土壤N-NH4含量增加了35%，硝酸盐含量减少了9%，N2O排放减少了50%。U-HA使土壤基础呼吸提高了10%，土壤微生物群落比活性提高了7%，提供了最高的代谢熵qCO2。与U-UI相比，U-HA主要表现为介于U-UI和U之间的效果。考虑到腐植酸原料成本低，U-HA可以被认为是减少土壤氮素损失的有前景的工具。

A geometric setting for generally nonconservative mechanical systems on fibred manifolds is proposed. Emphasis is put on an explicit formulation of nonholonomic mechanics when an unconstrained Lagrangian system moves in a generally non-potential force field depending on time, positions and velocities, and the constraints are nonholonomic, not necessarily linear in velocities. Equations of motion, and the corresponding Harniltonian equations in intrinsic form are given. Regularity conditions are found and a nonholonomic Legendre transformation is proposed, leading to a canonical form of the nonholonomic Hamiltonian equations for nonconservative systems.

Methodological problems of climatic reconstruction for different periods of Holocene are discussed on the basis of a multiple group biological analysis on peat-sapropel sediments. The possibility of biological analysis is exemplified by the paleoclimatic reconstruction for Carpathian and Altai Mountain ranges. For the ＂Skolevsky Beskidy＂ national park of Carpaty the paleoclimatic scenarios have been drown up aiming at the more precise definition of climatic conditions for the period of mass mountain slope terracing. The stability of terrace systems of various designs in the current climatic conditions has been assessed. It is shown that during periods of humid climate the terraces, whose designs have been focused on drainage, were built. In periods of dry and warm climate the terrace systems capable of accumulating water were built. Both these types of terrace systems are destroyed in nowadays. Only those terrace systems are stable which were adjusted by their builders to contrast variations of precipitation. For Western Altais the paleoclimatic scenario has been done to forecast the safety of the Bronze Age kurgans （burial earth mounds） with permafrost inside the construction. In the Altay region during the Holocene it has revealed two periods of sharp cooling, the peaks of which occurred in the intervals 4500- 4300 and 2500-2300 years pronounced climatic drying ago, and two periods of 4900-4700 and 130-70 years ago. Depletion of the algae composition in the layer corresponding to the last period of drying climate indicates a very sharp change in the parameters of moisture and turning the lake into a dry swamp. Periods of cold weather may have contributed to the formation of special ritual traditions of the Sakan tribes that require the frozen ground to bury the dead. The later climate fluctuations identified have not affected the safety of permafrost in burial mounds constructed in the V-III cc BC.
