The Inhibitory Effects of Cordyceps militaris ARA301 Extract on Lipopolysaccharide-Induced Lung Injury in vivo

mycolabadmin

Researchers tested a mushroom extract from Cordyceps militaris to see if it could protect mice from lung injury caused by bacterial toxins. The extract successfully reduced inflammation, prevented excessive mucus production, and decreased immune cell buildup in the lungs. These findings suggest that this mushroom extract could potentially be used as a natural supplement to help prevent respiratory diseases and support lung health.

Fungal Microbiome Diversity in Urban Forest Decreases Asthma and Allergic Inflammation

mycolabadmin

This study found that living near urban forests with diverse fungal species may protect against asthma. Researchers collected fungi from air samples in Seoul and found that areas with more forests had fewer asthma cases. Laboratory tests showed that fungi from forests were better at reducing allergic inflammation than fungi from city centers. The diversity of fungal species, rather than specific types, appeared to provide protective benefits.

On site discrimination between two closely related commercial strains of oyster mushroom using a loop-mediated isothermal amplification (LAMP) test

mycolabadmin

Scientists developed a quick molecular test to identify two specific commercial oyster mushroom strains (SPOPPO and ALLERPO) in less than 30 minutes using a technique called LAMP. These sporeless mushroom strains were created to reduce respiratory health problems that workers develop from inhaling mushroom spores. The new test helps mushroom producers and breeders quickly verify strain identity in the field to prevent unauthorized copying of these valuable varieties and to catch products of suspect origin.

From mold to mycotoxins: an LC–MS/MS method for quantifying airborne mycotoxins in indoor environments

mycolabadmin

Mold in water-damaged buildings produces toxic compounds called mycotoxins that can become airborne and be breathed in. This study developed a precise laboratory method to detect and measure 29 different mycotoxins in indoor air samples. Researchers tested the method in three real mold-infested buildings and successfully identified seven different mycotoxins, proving the method works well even when toxin levels are very low. This breakthrough helps determine whether moldy indoor environments pose serious health risks to workers and occupants.

Effects of Chronic Barley Consumption on Upper Respiratory Tract Symptoms in Japanese Healthy Adults: A Randomized, Parallel-Group, Controlled Trial

mycolabadmin

This study found that eating cooked waxy barley daily for 8 weeks reduced sneezing and nasal congestion in healthy adults compared to those eating white rice. Participants who ate barley also reported feeling less tired and experienced improved mood. The barley contains a fiber called β-glucan that appears to boost the body’s natural immune cells, helping protect against cold symptoms.

Armillaria mellea Mycelia Alleviate PM2.5-Induced Pulmonary Inflammation in Murine Models

mycolabadmin

This study found that Armillaria mellea mushroom mycelia can help protect lungs from damage caused by PM2.5 air pollution. When tested in both laboratory cells and mice, the mushroom extract reduced inflammatory responses and restored healthy lung function. The protective effects work by reducing harmful inflammatory molecules and blocking inflammatory signaling pathways. These findings suggest A. mellea could be developed into a natural supplement to help protect respiratory health in areas with poor air quality.

A mass spectrometry-based strategy for investigating volatile molecular interactions in microbial consortia: unveiling a Fusarium-specific induction of an antifungal compound

mycolabadmin

Scientists developed a new method to study how different fungi communicate and compete with each other through invisible chemical signals called volatile organic compounds. By growing three types of fungi together in a controlled setup, they discovered that Fusarium culmorum specifically produces a compound called γ-terpinene when in contact with other fungi. This compound acts as a natural antifungal agent, helping Fusarium fight off competing fungi. This research provides a blueprint for understanding complex fungal interactions in environments like human lungs and could eventually help diagnose or prevent fungal-related diseases.
