These differences are most likely due to the homogeneous distribution of the Lys groups in PGA compared to trypsin and chymotrypsin (where almost 50% of Lys group are in a small percentage of the protein surface). The results suggest that Tris could be affecting the multipoint covalent immobilization in two different ways, on one hand, reducing the number of available glyoxyl groups of the support during immobilization, and on the other hand, generating some steric hindrances that difficult the formation of covalent bonds.The need for producing renewable fuels from biomass has increased due to depleting fossil resources and environmental concerns. However, the low fraction of biomass carbon converted to product is an undeniable drawback for most current biofuel productions from fermentation due to undecomposed lignin in biomass composition and carbon loss as CO2. In this work, two main production routes of the MixAlco® process, the ketonization route (KR) and esterification route (ER) are evaluated for the mixed alcohol production by brown algae, a third-generation biomass without lignin. A novel fermentation process using syntrophic bacteria consortia (SBC) is developed to produce acetic acid from waste gas produced by KR and ER process. The paper investigates the integrated flowsheet for these alternative routes, using techno-economic and life cycle analysis to compare the minimum selling price and environmental impacts. From TEA, we find that the overall costs for KR and ER are lower than the SBC processes. The cost of ketonization routes is lower than esterification routes. The capital cost and operating cost for the ER+SBC process are the highest. Raw materials and utilities are the two major costs for all the processing routes examined. The MSP for the ER+SBC process is the lowest out of all four routes. ER process performs the best in terms of environmental impacts except in water depletion compared with other processes, while the KR process performs the worst regarding the environmental metrics.Lignin recovery from black liquor is an important task for producing valuable chemical products. Acidification processes are currently applied by pulp and paper industries for black liquor treatment, in which two main streams are produced the precipitated lignin fraction and a lignin-lean black liquor. Membrane filtration is a suitable alternative for lignin recovery from black liquor, but studies on lignin-lean black liquor filtration are scarce. Here, we evaluated the ultrafiltration process for lignin recovery from the both fractions of black liquor acidification. The lignin-lean black liquor presented 22 wt% of total solids with 4.6 wt% of lignin. Lignin retention from the lignin-lean black liquor by the 5 kDa ultrafiltration membrane was equal to 85%, with reduction in total solid concentration from 219.8 to 68.1 g L-1. Due to the relatively high solid concentration in the lignin-lean black liquor, cake formation was the main fouling mechanism during ultrafiltrations. The precipitated lignin solution prer cut-off should be proposed for lignin purification from the precipitated fraction.Vitamin K antagonists have been used for many years as the treatment of choice for long-term oral anticoagulation in patients with non-valvular atrial fibrillation. AZD0156 clinical trial Unfortunately, the use of those drugs in the real-world setting, particularly among elderly patients, is suboptimal because of their limitations in management. Therefore, many patients were not adequately anticoagulated. Direct oral anticoagulants have been demonstrated to overcome almost all the limitations derived from the use of vitamin K antagonists. Direct oral anticoagulants are at least as effective as vitamin K antagonists in preventing thromboembolic events in patients with non-valvular atrial fibrillation and safer in reducing the risk of intracranial haemorrhage and all-cause mortality. However, as a result of the strict inclusion and exclusion criteria applied to patients, data coming from randomized controlled trials might not apply to the general population. Furthermore, elderly patients were scarcely represented in randomized controlled trials with direct oral anticoagulants. Therefore in elderly patients with non-valvular atrial fibrillation, unmet clinical needs still exist. This review article highlights some of them and provides potential answers based on the results coming from randomized clinical trials, real-world data, and the authors' clinical experience.
The present study aimed to analyze the clinical features of ocular pathology in patients with acquired immunodeficiency syndrome (AIDS) combined with syphilis.
A total of 129 patients with AIDS and syphilis who first visited the Department of Ophthalmology in Beijing YouAn Hospital between 2012 and 2019 were included in the study. All patients underwent ophthalmologic examinations, such as best-corrected visual acuity (BCVA), slit lamp, intraocular pressure, dilated fundus examination, and color fundus photography as well as systemic examinations related to AIDS and syphilis. The patients were divided into four groups according to fundus disease a normal fundi group, an HIV-related microvascular retinopathy (MVR) group, a cytomegalovirus retinitis (CMVR) group, and a syphilis-related retinopathy group.
The incidence of fundus disease was 70.7%. There were 36 patients with normal fundi (29.3%), 40 with HIV-related MVR (31.0%), 25 with CMVR (19.4%) (including 11 cases of CMVR with syphilis-related retinopathy), 26 (20.2%) with syphilis-related retinopathy, 1 (0.78%) case with acute retinal necrosis, and 1 (0.78%) case with PORN. The median blood CD4 + T-cell count in the syphilis-associated retinopathy group was 357.5 cells/μl, which was significantly higher than in the other groups; this difference was statistically significant. In the CMVR group, 11 cases with concomitant syphilis-associated retinopathy had lower BCVA and 10 (90.9%) had active inflammatory manifestations in the anterior segment.
The incidence of ocular pathology was high in patients co-infected with AIDS and syphilis, which might manifest in a variety of ocular manifestations; some patients may also have multiple ocular changes, which should be given great clinical attention.
