AIM：To assess the impact of macular surgery on the functional and anatomic outcomes of the patients in different grades of epiretinal membrane（ERM）.METHODS：Seventy-one eyes of 71 patients who underwent 23-gauge transconjunctival sutureless pars plana vitrectomy for primary isolated ERM were evaluated in this ***：There were 38 females（53.5%） and 33 males（46.5%）.The average age of the patients was 68.1 y（range 42-89 y）.Mean follow up period was 14 mo（range 6-26 mo）.The cases were divided into two subgroups of cellophane maculopathy（CM） and macular pucker（MP）.An improvement was observed in the postoperative best-corrected visual acuity（BCVA）,as well as a decrement in central foveal thickness（CFT） in both groups（both of these being statistically significant;P=0.001）.In comparison between two groups,it was found that there was a significant improvement on BCVA and CFT in CM group than MP group（P=0.01）.Furthermore,the postoperative fundus findings regarding RPE alterations and macular edema were significantly higher in MP group when compared to the CM group（P=0.01）.CONCLUSION：ERM and internal limiting membrane peeling surgery can lead to a significant reduction of CFT and visual improvements in idiopathic ERM.A long-term ERM persistence will cause unrecoverable retinal damage and visual loss.

于2014年至2015年进行田间试验。本研究中,选用3种K施用量(0、10和20 kg K/da)的K_2SO_4肥(50%K_2O)和3种HA施用量(0、20和40kgHA/da)的商品腐植酸(85%HA)。HA施用量的增加对试验区土壤pH、盐分、有机质、P、Mg、Fe、Mn含量的影响在P<0.01水平上差异显著。研究表明,K施用量的增加对试验区土壤盐分、Mg、Fe和Cu含量的影响在P<0.01水平上差异显著。HA施用量的增加对小麦生物产量、籽粒产量和收获指数有显著影响(P<0.01),而K对小麦生育期没有任何影响。HA施用量的增加对籽粒和秸秆养分含量,P、K、Ca、Mg、Fe和Zn均有显著影响(P<0.01)。K施用量的增加对P、K、Mg、Fe、Zn含量有显著影响(P<0.01)。结果表明,在改善土壤性质、作物产量和养分含量方面,施用HA比施用K更有效。

A pandemic is not a new event encountered in the history of humanity because mankind has faced various pandemics in history. The common point of pandemics is their serious negative effects on the global economy. Considering the food supply chain, one of the most important sectors of the economy, it has been seen that COVID-19 has an impact on the whole process from the field to the consumer. In the light of recent challenges in food supply chain, there is now considerable concern about food production, processing, distribution, and demand. COVID-19 resulted in the movement restrictions of workers, changes in demand of consumers, closure of food production facilities, restricted food trade policies, and financial pressures in food supply chain. Therefore, governments should facilitate the movement of workers and agri-food products. In addition, small farmers or vulnerable people should be supported financially. Facilities should change the working conditions and maintain the health and safety of employees by altering safety measures. Food protectionist policies should be avoided to prevent an increase in food prices. In conclusion, each country must realize the severity of the situation and sometimes should tighten or loosen the measures according to the spread of the pandemic. The supply chain also should be flexible enough to respond to the challenges in the food supply chain. The purpose of this review is to evaluate the impact of COVID-19 on the agriculture and food sector and to summarize the recommendations required to reduce and control the effect of the pandemic.

Balo's concentric sclerosis(BCS) is a rare monophasic demyelinating disease known as multiple sclerosis subtype and seen as a round lesion with variable hyper and hypodetoxification layers. Characteristic appearance can be seen as "bulb eye" or "onion bulb". The initial terminology for this neurological disorder was leukoencephalitis periaxialis concentrica; this is defined as a disease in which the white matter of the brain is destroyed in concentric layers in such a way as to leave the axial cylinders intact. This report presents a case of BCS with spontaneous healing of the patient and a mass lesion with concentric rings adjacent to the left lateral ventricle and the posterior portion of the corpus callosum with peripheral vasogenic edema. The neurological lesion of the patient was similar to the magnetic resonance imaging and clinical findings of the BCS.

The changes in fatty acid compositions during nutritional interaction among almond Amygdalus communis Linnaeus （Rosales： Rosaceae）（host plant）, lacebug Monosteria unicostata （Mulsant and Rey）（Heteroptera： Tingidae） and its predator Piocoris luridus Fieber （Heteroptera： Lygaeidae） were determined by gas chromatography and gas chromatography-mass spectrometry analyses. The fatty acid profiles of phospholipids and triacylglycerols were substantially different. Unlike the general observations for virtually most terrestrial insects, arachidonic and eicosapentaenoic acids were detected in high proportions of phospholipid fractions in both insects, especially in P. luridus. Also the almond tissues provide very little oleic acid to the herbivore diet, yet both insect species developed high proportions of this component. Our data reveals instances of specific accumulation of fatty acid biosynthesis, elongation/desaturation, and not incorporating selected fatty acids into cellular lipids.

As known, the method to obtain a sequence space by using convergence field of an infinite matrix is an old method in the theory of sequence spaces. However, the study of convergence field of an infinite matrix in the space of almost convergent sequences is so new （see [15]）. The purpose of this paper is to introduce the new spaces ^ ～f and fo consisting of all sequences whose Ceshro transforms of order one are in the spaces f and ^ ～ f0, respectively. Also, in this paper, we show that ^ ～f and ^ ～f0 are linearly isomorphic to the spaces f and f0, respectively. The β- and γ-duals of the spaces ^ ～f and 2% are computed. Furthermore, the classes （^ ～f： μ） and （μ ： f） of infinite matrices are characterized for any given sequence space μ, and determined the necessary and sufficient conditions on a matrix A to satisfy Bc-core（Ax） K-core（x）, K-core（Ax） Bg-core（x）, Bc-core（Ax） Be-core（x）, Bc-core（Ax） t-core（x） for all x ∈ t∞.
