Worldwide, tropospheric ozone (O) is a potential threat to wood production, but our understanding of O economic impacts on forests is still limited. To overcome this issue, we developed an approach for integrating O risk modelling and economic estimates, by using the Italian forests as a case study. Results suggested a significant impact of O expressed in terms of stomatal flux with an hourly threshold of uptake (Y = 1 nmol O m leaf area s to represent the detoxification capacity of trees), i.e. POD1. In 2005, the annual POD1 averaged over Italy was 20.4 mmol m and the consequent potential damage ranged from 790.90 M€ to 2.85 B€ of capital value (i.e. 255-869 € ha, on average) depending on the interest rate. The annual damage ranged from 31.6 to 57.1 M€ (i.e. 10-17 € ha per year, on average). There was also a 1.1% reduction in the profitable forest areas, i.e. with a positive Forest Expectation Value (FEV), with significant declines of the annual national wood production of firewood (- 7.5%), timber pole (- 7.4%), roundwood (- 5.0%) and paper mill (- 4.8%). Results were significantly different in the different Italian regions. We recommend our combined approach for further studies under different economic and phytoclimatic conditions.
In this study we monitored exposure to airborne dust in workers performing various tasks at two biomass-fuelled thermal power plants (27 and 46 MW) over six years. The plants are mainly fuelled by forest wood chips and, to a lesser extent, by agro-food products, with annual consumption of about 300 and 450 kt. We focused on inhalable wood dust because of its potential carcinogenicity to humans.
Environmental contamination with biofilm can be a source of healthcare-associated infections. Disinfection with various biocidal active substances is usually the method of choice to remove contamination with biofilm. In this study we tested 13 different disinfection protocols using gaseous ozone, citric acid, and three working concentrations of benzalkonium chloride-based professional disinfecting products on 24-hour-old biofilms formed by two strains on ceramic tiles.
Introduction: The utility of pancreaticoduodenectomy (PD) for high-grade traumatic injuries remains unclear and data surrounding its use are limited. We hypothesized that PD does not result in improved outcomes when compared with non-PD surgical management of grade IV-V pancreaticoduodenal injuries.
Methods: This is a retrospective, multicenter analysis from 35 level 1 trauma centers from January 2010 to December 2020.

Rattan is a multi-purpose plant resource in the tropical forest treasure house. With its good technological characteristics, it has become an excellent material for the preparation of industry. The original rattan is an important forest product second only to wood and bamboo.
Abundant wood waste is generated globally, but the literature lacks a framework distinguishing sustainable versus unsustainable reuse practices. This gap hinders policy makers and stakeholders from effectively supporting responsible resource utilization. As such, this scoping review aimed to address this gap by evaluating wood waste reuse practices through ecological, financial, and social sustainability lenses.
