(Press-News.org) A novel oral amphotericin B (MAT2203) developed by Matinas BioPharma for treatment of invasive mucormycosis (IM) and other deadly invasive fungal infections, has demonstrated encouraging results in a series of preclinical studies. The groundbreaking research, led by Lundquist Institute (TLI) Investigator Ashraf Ibrahim, PhD, has been published in the journal Antimicrobial Agents and Chemotherapy.
The studies focused on MAT2203, an oral lipid nanocrystal formulation of amphotericin B, which has previously demonstrated safety and effectiveness in the clinical treatment of various fungal infections. The research aimed to evaluate the efficacy of MAT2203 in comparison to the current standard treatment, liposomal amphotericin B (LAMB), in a neutropenic mouse model. This model mimics the human condition of IM caused by two strains of fungus, Rhizopus arrhizus var. delemar and Mucor circinelloides f. jenssenii DI15-131.
Results indicated that a daily dose of 15 mg/kg of MAT2203 was as effective as 10 mg/kg of LAMB in extending the median survival time and improving overall survival rates. Furthermore, while both treatments significantly reduced the fungal burden in the lungs and brains of infected mice, LAMB showed a more pronounced effect in reducing tissue fungal load compared to MAT2203 when dealing with R. delemar infections.
Dr. Ibrahim commented on the findings, stating, "The promising outcomes of MAT2203 in this study represent a significant step towards a less invasive and safer treatment approach to combating invasive mucormycosis since unlike LAMB which is given intravenously, MAT2203 is administered orally and can be administered long-term without any of the significant toxicities associated with LAMB treatment. It's a testament to the potential of innovative drug delivery systems like lipid nanocrystals in transforming how we treat infectious diseases."
A higher dosage of MAT2203 (45 mg/kg) did not show added benefits and was less tolerated by the mice, highlighting the importance of dosing in the development of this treatment.
These findings support the continued research and development of MAT2203 as a novel oral treatment option for patients suffering from mucormycosis, potentially offering a safer, more effective, and convenient alternative to current therapies.

Deep-learning decoding for a noninvasive brain-computer interface
2024-04-30
Brain-computer interfaces (BCIs) have the potential to make life easier for people with motor or speech disorders, allowing them to manipulate prosthetic limbs and employ computers, among other uses. In addition, healthy and impaired people alike could enjoy BCI-based gaming. Non-invasive BCIs that work by analyzing brain waves recorded through electroencephalography are currently limited by inconsistent performance. Bin He and colleagues used deep-learning decoders to improve a BCI’s performance responding to ...
Elucidating the role of a shared lncRNA-miRNA-mRNA network in exacerbating Parkinson’s disease symptoms in the context of COVID-19 infection
2024-04-30
Background and objectives
Parkinson’s disease (PD) is a common neurodegenerative disorder with unclear molecular mechanisms. Noncoding RNAs, such as microRNAs (miRNAs) and long noncoding RNAs (lncRNAs), have been identified as critical regulators of gene expression. This study aimed to investigate the triple network of lncRNA-miRNA-mRNA, known as competing endogenous RNAs (ceRNAs), and to identify essential lncRNAs that regulate PD-related gene expression through their target miRNAs. The study also identified a common triple network between COVID-19 and PD that may contribute to exacerbating PD symptoms.

American College of Lifestyle Medicine announces unique screening tool for clinicians to efficiently assess patient dietary patterns
2024-04-30
The American College of Lifestyle Medicine (ACLM) has developed a clinical tool to help health care professionals incorporate a food as medicine approach into their practice by assessing and tracking the proportion of whole, unrefined plant-based foods and water intake in their patients’ dietary patterns.
The ACLM Diet Screener, a 27-item diet assessment tool available free on ACLM’s website, was designed to guide clinical conversations around diet and support nutrition prescriptions, while also being brief enough for use during routine ...
Cranberry extracts could boost microbiota and counter cardiometabolic diseases
2024-04-30
Québec, April 30, 2024 - Cranberry extracts appear to improve intestinal microbiota and help prevent chronic diseases such as diabetes and cardiovascular diseases. The study of Université Laval and the Institute of Nutrition and Functional Foods (INAF) reported beneficial effects after only four days of use.
Cranberries and berries are associated with multiple health benefits, mainly attributed to their high content of polyphenols, in the form of tannins. They also contain high concentrations of oligosaccharides, small fibres that are thought to contribute to their bioactivity.
The research team, led by Yves Desjardins, professor ...
Discovery of uranium-contaminated soil purification material without secondary environmental pollution
2024-04-30
Nuclear energy has long been regarded as a next-generation energy source, and major countries around the world are competing to secure cutting-edge technologies by leveraging the high economic efficiency and sustainability of nuclear power. However, uranium, which is essential for nuclear power generation, has serious implications for both soil ecosystems and human health. Despite being a key radioactive material, uranium poses significant health risks due to its chemical toxicity to the kidneys, bones, and cells. As a result, both the U.S. Environmental Protection Agency and the World Health Organization recommend allowing and advocating for uranium concentrations in wastewater ...
The carbon emissions of academic astronomy
2024-04-30
The carbon emissions associated with air travel to professional conferences make up a sizable fraction of the emissions produced by academia. Andrea Gokus and colleagues estimated the CO2-equivalent emissions for conference travel to all 362 open meetings in the field of astronomy in 2019. The total is an estimated 42,500 tCO2e, or about one ton per participant per meeting. According to the authors, networking and discussing new scientific developments at meetings is important for advancing the field, but adjustments can be made to reduce the hefty carbon cost. Holding meetings virtually ...

Great strides in the development of high refractive index polymers for optoelectronics
2024-04-30
Optoelectronic devices have found their way into many aspects of our daily lives, from OLED displays to photodetectors, security systems, and environmental monitoring. In all the applications, these devices utilize high refractive index polymers (HRIPs) to control light.
In general, the optical properties of transparent HRIPs enable efficient light transmission and manipulation, allowing optoelectronics devices to guide and control the flow of light to improve their performance. However, there are no low-cost options for HRIPs that can guarantee good optical performance while being transparent and environmentally ...
Engineered increase in mesophyll conductance improves photosynthetic efficiency in field trial
2024-04-30
It is possible to engineer increased mesophyll conductance in plants according to new research from the University of Illinois. Mesophyll conductance plays a key role in photosynthesis and refers to the ease with which CO2 can diffuse through a leaf’s cells before reaching the location where it is ultimately turned into sugar to feed the plant (carbon fixation). CO2 faces barriers as it moves through the leaf, including its own cell walls. Researchers from the Long Lab found that by increasing permeability and slightly reducing the thickness of cell walls, they could increase CO2 diffusion and uptake in a model crop.
“This is one of the ...
