Fungal contamination in the air of hospital wards can affect the health of medical staff, patients, and caregivers. Through systematic analysis of the concentration, types, and particle size distribution characteristics of fungi in the air of wards in Wuhan, China, in 2023, it was found that there was no significant correlation between the concentration of fungi in the air of wards and the disease type and personnel density. The main influencing factors were temperature, humidity, and seasonal changes. The distribution characteristics of fungal particle size in the wards of various departments in winter and summer showed a roughly normal distribution, with the percentage of particle size gradually increasing from stage I to stage III. The proportion from stage III to stage V was generally the highest, while the proportion from stage V to stage VI gradually decreased. There was no significant difference in the median diameter of airborne fungal conidia between different departments in winter and summer, and the median diameter of fungal conidia was less than 3.19 μm. The dominant fungal genus in the wards during winter and summer were basically the same, and there was no significant difference compared to wards in other inpatient buildings. The current study indicates that more attentions should be paid to the increasing of filtration efficiency of fungal conidia particle sized from 1.1~4.7 μm, and appropriate antifungal and sterilization drugs, equipments and methods should be selected in the maintenance of daily hygiene, including the operation and management of the air conditioning systems in the inpatient wards.

Background: Naringenin, a flavonoid compound found in citrus fruits, possesses valuable anticancer properties. However, its potential application in cancer treatment is limited by poor bioavailability and pharmacokinetics at tumor sites. To address this, Naringenin nanoparticles (NARNPs) were prepared using the emulsion diffusion technique and their anticancer effects were investigated in HepG2 cells.

Functionalization of polymer nanoparticles (NPs) with targeting peptides is of interest for drug delivery applications to enhance tumor accumulation and penetration. Herein, we evaluated the feasibility of two different methods for the attachment of a tumor-penetrating peptide LinTT1 (AKRGARSTA) to poly(ethylene glycol)-block-poly(ε-caprolactone) (PCL-PEG) NPs: (1) "post-conjugation" onto pre-formed nanoparticles, and (2) "pre-conjugation", the synthesis and purification of peptide-polymer conjugates and subsequent nanoprecipitation of the conjugates diluted with non-functionalized polymers. Conjugation of the labelled peptide via maleimide-thiol chemistry was verified by gel permeation chromatography (GPC) and fluorescence measurements.

Paddy fields are a major anthropogenic source of global methane (CH) emissions, a powerful greenhouse gas (GHG). This study aimed at gaining insights of different organic and inorganic conductive materials (CMs) - biochar, fungal melanin, and magnetite - to mitigate CH emissions, and on their influence on key microbial populations, mimicking the postharvest season throughout the degradation of rice straw in microcosms under anaerobic conditions encompassing postharvest paddy rice soils from the Ebro Delta, Spain. Results showed that fungal melanin was the most effective CM, significantly reducing CH emissions by 29 %, while biochar amendment also reduced emissions by 10 %.

The lack of cost-effective nutrient sources and harvesting methods is currently a major obstacle to the production of sustainable biofuels from microalgae. In this study, Chlorella pyrenoidosa was cultured with saline wastewater in a stirred photobioreactor, and lipid-rich flocculent microalgae particles were successfully constructed. As the influent salinity of the photobioreactor increased from 0% to 3%, the particle size and sedimentation rate of flocculent microalgae particles gradually increased, and the lipid accumulation of microalgae also increased gradually.
