Sci Total Environ 2021 Apr 29;786:147390. Epub 2021 Apr 29.

Western Paraná State University, 85819-110 Cascavel, PR, Brazil; Federal University of Fronteira Sul, 99700-000 Erechim, Brazil; Embrapa Suínos e Aves, 89715-899 Concórdia, SC, Brazil. Electronic address:

Organic carbon can affect the biological nitrogen removal process since the Anammox, heterotrophic and denitrifying bacteria have different affinities and feedback in relation to carbon/nitrogen ratio. Therefore, we reviewed the wastewater carbon concentration, its biodegradability and bioavailability to choose the appropriate nitrogen removal process between conventional (nitrification-denitrification) and Anammox-based process (i.e. Read More

Mechanical thrombectomy in distal residual occlusions of the middle cerebral artery after large vessel recanalization in acute stroke: 2b or not 2b? A pragmatic approach in real-life scenarios.

World Neurosurg 2021 May 5. Epub 2021 May 5.

Hopital Foch, Department of Diagnostic and Interventional Neuroradiology, Suresnes, Île-de-France, FR.

Background: AND PURPOSE: Recent studies have suggested that a recanalization grade of modified thrombolysis in cerebral infarction (mTICI) ≥2c is strongly related with good clinical outcome rather than the current therapeutic angiography target ≥2b. In order to achieve better recanalization, additional further maneuvers on distal residual vessel occlusion may be required. The aim of this paper was to evaluate the safety and efficacy of rescue treatment in residual vessel occlusions (RVOs) after recanalization of large vessel occlusions in the anterior circulation.

Systematic evaluation of activated carbon-FeO composites for removing and degrading emerging organic pollutants.

Environ Res 2021 May 5:111187. Epub 2021 May 5.

Civil and Environmental Engineering Faculty, Technion, Haifa, 32000 Israel. Electronic address:

In this study, a comparative activity assessment of several activated carbon (AC) and AC-FeO composites was performed to evaluate their efficiency and versatility as Fenton-like catalysts. Although many studies have demonstrated the advantages of AC-based materials as Fenton-like catalysts, most have been developed using only one oxidant and/or one pollutant. Here, untreated (AC) and acid-treated AC (AC) iron-oxide composites were synthesized, characterized, and compared in terms of activity to bare ACs using several oxidants and pollutants, the activation efficiency of hydrogen peroxide (HO) and ammonium persulfate ((NH)SO), and the subsequent oxidation extent and kinetics of bisphenol-A, atrazine, and carbamazepine by the AC-based materials were studied in depth.

Property modelling of lysozyme-crosslinker-alginate complexes using latent variable methods.

J Biomed Mater Res A 2021 May 8. Epub 2021 May 8.

Department of Chemical Engineering, McMaster University, Hamilton, Ontario, Canada.

Statistical methods were used to provide insight into a polymer complex system composed of lysozyme and alginate to quantify the effects of such parameters as pH, and ionic composition of the mixing solution on the properties of the complexes including composition, particle diameter, and zeta potential. Various crosslinkers (calcium, barium, iron[III], and bovine serum albumin), were used with lysozyme for complex formation to investigate the effect of crosslinker charge density on protein release kinetics, modelled using kt . Multivariate statistical analysis showed that the kinetic parameters associated with the release were, not surprisingly highly dependent on the ionic strength of the release media, with higher ionic strength leading to faster release.

Conscious rat PET imaging with soft immobilization for quantitation of brain functions: comprehensive assessment of anesthesia effects on cerebral blood flow and metabolism.

EJNMMI Res 2021 May 8;11(1):46. Epub 2021 May 8.

Preeminent Medical Photonics Education and Research Center, Hamamatsu University School of Medicine, 1-20-1 Handayama, Higashi-ku, Hamamatsu, Shizuoka, 431-3192, Japan.

Background: Animal brain functions evaluated by in vivo imaging under anesthesia can be affected by anesthetic agents, resulting in incorrect assessment of physiological brain function. We therefore performed dynamic positron emission tomography (PET) imaging of conscious rats using recently reported soft immobilization to validate the efficacy of the immobilization for brain function assessments. We also determined the effects of six anesthetic agents-a mixed anesthetic agent (MMB), ketamine + xylazine (KX), chloral hydrate (Chloral), pentobarbital (PTB), propofol (PF), and isoflurane (IFL)-on brain function by comparison with conscious rats.

Treating high-risk moderate acute malnutrition using therapeutic food compared with nutrition counseling (Hi-MAM Study): a cluster-randomized controlled trial.

Am J Clin Nutr 2021 May 8. Epub 2021 May 8.

Project Peanut Butter, Freetown, Sierra Leone.

Background: There is a lack of consensus on what is the most appropriate treatment of moderate acute malnutrition (MAM).

Objectives: We aimed to determine if provision of ready-to-use-therapeutic food (RUTF) and antibiotics to "high-risk" MAM (HR-MAM) children in addition to nutritional counseling would result in higher recovery and less deterioration than nutrition counseling alone.

Methods: At the 11 intervention clinics, HR-MAM children were given RUTF and amoxicillin along with standard nutrition counseling, for 2-12 wk. Read More

Nan Fang Yi Ke Da Xue Xue Bao 2021 Apr;41(4):536-542

Department of Hematology, Nanfang Hospital, Southern Medical University, Guangzhou 510515, China.

Objective: To explore the clinical phenotype and changes in joint structure and function in adolescent patients with severe hemophilia A under different doses of FVIII.

Objective: Forty- three adolescents with severe hemophilia A aged 4-18 years were divided into on-demand group (=7), low-dose group (FVIII dose of 10-15 U/kg, 2-3 times a week, and ≤30 U/kg a week; =17), and intermediate-dose group (FVIII dose of 15-20 U/kg, 2-3 times a week, and 45-60 U/kg a week (=19). The 3 groups were compared for their clinical bleeding phenotype, annual bleeding rate (ABR), annual joint bleeding rate (AJBR), annual the most severe joint bleeding rate, joint imaging scores (ultrasound HEAD-US score and IPSG MRI score), Hemophilia Joint Health Score (HJHS) and Functional Independence Score in Hemophilia (FISH) within 24 months.
