Dissolved organic carbon (DOC) is an important function of soil organic carbon and sensitive to environmental disturbance. Few studies have explored the variations in soil DOC dynamics and effects on soil physicochemical properties following prescribed burnings. In this study, Pinus koraiensis plantation forests in Northeast China were selected and subjected to prescribed burning in early November 2018. Soil DOC and different soil physicochemical and biological properties in the 0-10 cm and 10-20 cm soil layers were sampled six times within two years after a prescribed burning. In this study, some soil physicochemical (SOC, TN, and ST) and microbial biomass properties (MBC) recovered within two years after a prescribed burning. Compared to the unburned control stands, the post-fire soil DOC concentrations in the upper and lower soil layers increased by 16% and 12%, respectively. Soil DOC concentrations varied with sampling time, and peaked one year after the prescribed burning. Our results showed that soil chemical properties (NH-N and pH) rather than biological properties (microbial biomass) were the main driving factors for changes in post-fire soil DOC concentrations. Current study provides an important reference for post-fire and seasonal soil C cycling in plantation forests of Northeast China.

Peatlands are significant global carbon sinks; however, their carbon storage functions are vulnerable to human activities. In the Greater Khingan Mountains of Northeast China, where forest and peatland ecosystems are interspersed extensively, prescribed burning is conducted annually on peatlands to prevent major forest fires. To investigate the effect of prescribed burning on carbon and nutrient cycling processes in peatlands, we conducted a three-year experiment in the Greater Khingan Mountains.

Background: Although topical corticosteroids (TCS) represent first-line treatment for vulvar lichen sclerosus (VLS) and as such should be prescribed to all women at time of diagnosis, approximately 30% of patients do not experience complete symptom resolution following such treatment. TCS may not effectively improve vulvar trophism and elasticity, both of which are crucial for sexual function. Owing to its regenerative and healing properties, cord blood platelet-rich plasma (CB-PRP) may represent an efficacious supplementary therapy, to be administered following first line treatment with TCS.

Changes in climate and land-use have significantly increased both the frequency and intensity of wildland fires globally, exacerbating the potential for hazardous impacts on human health. A better understanding of particle exposure concentrations and scenarios is crucial for developing mitigation strategies to reduce the health risks. Here, PM and black carbon (BC) concentrations were monitored during wildland fires between 2022-2024, in fire-prone areas in Catalonia (NE Spain), by means of personal monitors (AirBeam2 and Micro-aethalometers AE51 and MA200).

Introduction: Enterally-based resuscitation (EResus) is safe, efficacious, and has operational advantages, particularly in low-resource settings. However, there is a lack of real-world effectiveness studies and evidence-based protocols, which hinders implementation. To address this gap, we conducted a feasibility study ahead of a randomized controlled trial (RCT) of enterally based versus usual resuscitation at a tertiary burn center in Nepal which had no prior clinical trial experience.

Forty percent of terrestrial ecosystems require recurrent fires driven by feedbacks between fire and plant fuels. The accumulation of fine fuels in these ecosystems play a key role in fire intensity, which alters soil nutrients and shapes soil microbial and plant community responses to fire. Changes to post-fire plant fuel production are well known to feed back to future fires, but post-fire decomposition of new fuels is poorly understood.
