Effect of Metal Ions, Chemical Agents and Organic Compounds on Lignocellulolytic Enzymes Activities

, 2017
Lignocellulolytic enzymes have been extensively studied due to their potential for indus- trial applications such as food, textile, pharmaceutical, paper, and, more recently, energy.

Health criteria and scope of workers’ periodic health check-ups for selected types of work and exposure factors – Nofer Institute of Occupational Medicine guidelines

Medycyna Pracy, 2019
Workers’ medical prophylactic examinations referred to in the Labor Code are one of the tasks of the occupational medicine services. They are regulated by law which has been in force for more than 20 years in unchanged form.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

“Is that a coincidence?”: Exploring health perceptions and the causal attributions of physical health conditions in British nuclear test veterans

SSM: Qualitative Research in Health, 2022
Since the British nuclear testing programme, there have been several claims in the media and from the veterans themselves that their health (and descendants' health) has been adversely affected by ionizing radiation exposure.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Are Natural Compounds a Promising Alternative to Synthetic Cross-Linking Agents in the Preparation of Hydrogels?

Pharmaceutics, 2023
The main aim of this review is to assess the potential use of natural cross-linking agents, such as genipin, citric acid, tannic acid, epigallocatechin gallate, and vanillin in preparing chemically cross-linked hydrogels for the biomedical ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Geotechnical characteristics of saline soft soils improved by chemical agents

Magazine of Civil Engineering
Chemical stabilization is a typical method for enhancing salinity in soils. In this regard, an effort has been made to evaluate the effect of chemical substances and stabilizers of Portland cement on the geotechnical characteristics of salt soils. Due to
