Effects of dynamic adsorption on bubble formation and coalescence in partitioned-EDGE devices.

J Colloid Interface Sci 2021 Jun 4;602:316-324. Epub 2021 Jun 4.

Wageningen University, Food Process Engineering Group, Bornse Weilanden 9, 6708 WG Wageningen, The Netherlands. Electronic address:

Hypothesis: Dynamic adsorption effects can play a crucial role in bubble formation and stabilization. We hypothesize that microfluidic tools provide direct insights to these effects, and that the final bubble size depends on the intersection of time scales for bubble formation versus adsorption of proteins.

Experiments: We use a microfluidic device to study Laplace pressure-driven formation of bubbles that are stabilized by whey proteins. Read More

Indicator of redox in soil (IRIS) films as a water management tool for rice farmers.

J Environ Manage 2021 Jun 12;294:112920. Epub 2021 Jun 12.

Department of Plant and Soil Sciences, 531 S. College Avenue, Townsend Hall Rm 152, University of Delaware, Newark, DE, 19716, USA. Electronic address:

Rice is a crucial part of the world's food supply but is also susceptible to uptake of contaminants including arsenic (As) and cadmium (Cd) depending on the soil redox potential. Careful control of soil redox state by implementing alternate wetting and drying (AWD) water management can decrease mobility of soil As and Cd, but can be difficult to manage. Indicators of reduction in soil (IRIS) tubes and films have been studied by pedologists for wetland delineation; here, we explore the use of the IRIS film technology as passive samplers of soil redox potential in rice paddies.

Transcatheter aortic valve replacement in bicuspid valves: The synergistic effects of eccentric and incomplete stent deployment.

J Mech Behav Biomed Mater 2021 Jun 7;121:104621. Epub 2021 Jun 7.

Department of Mechanical and Materials Engineering, University of Denver, Denver, CO, USA. Electronic address:

Bicuspid aortic valve is a congenital cardiac anomaly and common etiology of aortic stenosis. Given the positive outcomes of transcatheter aortic valve replacement (TAVR) in low-risk patients, TAVR will become more prevalent in the future in the treatment of severe bicuspid valve stenosis. However, asymmetrical bicuspid valve anatomy and calcification can prevent the circular and complete expansion of transcatheter aortic valves (TAVs). Read More

Knockdown of CDK5 down-regulates PD-L1 via the ubiquitination-proteasome pathway and improves antitumor immunity in lung adenocarcinoma.

Transl Oncol 2021 Jun 12;14(9):101148. Epub 2021 Jun 12.

Department of Shanghai Lung Cancer Center, Shanghai Chest Hospital, Shanghai Jiao Tong University, 241 Huaihai West Road, Shanghai 200030, PR China. Electronic address:

Although immunotherapy (anti-PD-1/PD-L1 antibodies) has been approved for clinical treatment of lung cancer, only a small proportion of patients respond to monotherapy. Hence, understanding the regulatory mechanism of PD-L1 is particularly important to identify optimal combinations. In this study, we found that inhibition of CDK5 induced by shRNA or CDK5 inhibitor leads to reduced expression of PD-L1 protein in human lung adenocarcinoma cells, while the mRNA level is not substantially altered.

Effects of semantic variables on word production in aphasia.

Cortex 2021 Apr 20;141:363-402. Epub 2021 Apr 20.

Department of Cognitive Science, Macquarie University, NSW, Australia.

Words differ in the complexity of their semantic representations and their relationships to other words and these differences can be operationalised as a variety of semantic variables. The research presented here investigates how word production in aphasia is influenced by six feature-based semantic variables (number of near semantic neighbours, semantic similarity, number of semantic features, typicality, intercorrelational density, and distinctiveness). Previous research has reported inconsistent findings for some of the semantic variables, while others have not been previously studied in aphasia. Read More

Trimethylacetic anhydride-based derivatization facilitates quantification of histone marks at the MS1 level.

Mol Cell Proteomics 2021 Jun 12:100114. Epub 2021 Jun 12.

Central European Institute of Technology, Masaryk University, Kamenice 5, 625 00 Brno, Czech Republic; Faculty of Science, Masaryk University, Kamenice 5, 625 00 Brno, Czech Republic. Electronic address:

Histone post-translational modifications (hPTMs) are epigenetic marks that strongly affect numerous processes, including cell cycling and protein interactions. They have been studied by both antibody- and mass spectrometry-based methods for years, but the analyses are still challenging, mainly due to the diversity of histones and their modifications arising from high contents of reactive amine groups in their amino acid sequences. Here, we introduce use of trimethylacetic anhydride (TMA) as a new reagent for efficient histone derivatization, which is a requirement for bottom-up proteomic hPTM analysis. Read More

Landfast ice: a major driver of reproductive success in a polar seabird.

Biol Lett 2021 Jun 16;17(6):20210097. Epub 2021 Jun 16.

Centre d'Études Biologiques de Chizé (CEBC), CNRS UMR 7372, 79360 Villiers en Bois, France.

In a fast-changing world, polar ecosystems are threatened by climate variability. Understanding the roles of fine-scale processes, and linear and nonlinear effects of climate factors on the demography of polar species is crucial for anticipating the future state of these fragile ecosystems. While the effects of sea ice on polar marine top predators are increasingly being studied, little is known about the impacts of landfast ice (LFI) on this species community. Read More

Functional and radiological outcome after forearm plating in children and adolescent fracture.

Acta Orthop Belg 2021 Mar;87(1):143-149

The literature on forearm overgrowth after plating in traumatic conditions is relatively poor though this technique can be useful when intra-medullary nailing is not sufficient in pediatric cases. The goal of this study was to assess a potential overgrowth after plating and identify impact on function. We conducted a retrospective study of all pediatric patients who underwent open surgery of the radius and/or ulna diaphysis with internal fixation by plating, in our institution, between October 2013 and July 2019.

The role of homeobox gene-encoded transcription factors in regulation of phototransduction: Implementing the primary pinealocyte culture as a photoreceptor model.

J Pineal Res 2021 Jun 15:e12753. Epub 2021 Jun 15.

Department of Neuroscience, Faculty of Health and Medical Sciences, University of Copenhagen, Copenhagen, Denmark.

Homeobox genes encode transcription factors controlling development; however, a number of homeobox genes are expressed postnatally specifically in melatonin-producing pinealocytes of the pineal gland and photoreceptors of the retina along with transcripts devoted to melatonin synthesis and phototransduction. Homeobox genes regulate melatonin synthesis in pinealocytes, but some homeobox genes also seem to be involved in regulation of retinal phototransduction. Due to the lack of photoreceptor models, we here introduce rat pinealocyte culture as an in vitro model for studying retinal phototransduction. Read More

Osmolyte enhanced aqueous two-phase system for virus purification.

Biotechnol Bioeng 2021 Jun 15. Epub 2021 Jun 15.

Department of Chemical Engineering, Michigan Technological University, Houghton, Michigan, USA.

Due to the high variation in viral surface properties, a platform method for virus purification is still lacking. A potential alternative to the high-cost conventional methods is aqueous two-phase systems (ATPSs). However, optimizing virus purification in ATPS requires a large experimental design space, and the optimized systems are generally found to operate at high ATPS component concentrations. Read More

Multiple in vivo Effects of Cadmium on Photosynthetic Electron Transport in Pea Plants.

Photochem Photobiol 2021 Jun 15. Epub 2021 Jun 15.

Department of Biophysics, Faculty of Biology, Lomonosov Moscow State University, Moscow, 119991, Russia.

The inhibitory effects of cadmium (CdSO ) on the primary photosynthetic processes were studied in vivo in Pisum sativum by using Multi-function Plant Efficiency Analyser (M-PEA-2). Photosynthetic parameters related to photosystem (PS) II, PS I and intersystem electron carriers were calculated from the light-induced kinetics of prompt chlorophyll a fluorescence (OJIP transient), delayed chlorophyll a fluorescence (DF), and 820 nm modulated reflection (MR). Low-dose exposure to cadmium (20 μM CdSO for 48 h) reduced probability of electron transfer from plastoquinones to the terminal electron acceptors of PSI (δ ) accompanied by a decrease in the rate of P and PC reduction (V ) and the magnitude of the I step on the DF kinetics.
