The new era of add-on asthma treatments: where do we stand?

Allergy Asthma Clin Immunol 2022 May 21;18(1):42. Epub 2022 May 21.

Division of Pulmonary, Critical Care, and Sleep Medicine, Yale Center for Asthma and Airway Disease, Yale University School of Medicine, New Haven, CT, USA.

Globally, a small proportion (5-12%) of asthma patients are estimated to have severe disease. However, severe asthma accounts for disproportionately high healthcare resource utilization. The Global Initiative for Asthma (GINA) management committee recommends treating patients with asthma with inhaled corticosteroids plus long-acting β-agonists and, when needed, adding a long-acting muscarinic receptor antagonist or biologic agent.

Technical advances on current research trends and explore the future scope on nutrient recovery from waste-streams: a review and bibliometric analysis from 2000 to 2020.

Environ Sci Pollut Res Int 2022 May 21. Epub 2022 May 21.

Department of Earth and Environmental Studies, National Institute of Technology Durgapur, West Bengal, India.

An exponentially growing global population has led to an increase in nutrient pollution in different aqueous bodies. Although different processes have successfully removed nutrients from wastewater on a large scale, a limited number of studies have been reported on efficiency, cost-effectiveness, and future potential of physical, chemical, and biological nutrient recovery methods to overcome the depletion of natural resources. Therefore, researchers need to understand current research trends by applying different approaches to investigate higher efficient nutrient recovery technologies. Read More

[hPG and cancer: A new blood biomarker in development for patient monitoring].

Bull Cancer 2022 May 18. Epub 2022 May 18.

Institut régional du Cancer de Montpellier (ICM), Unité d'Oncologie Médicale, Val d'Aurelle, 208, avenue des Apothicaires, 34298 Montpellier cedex 5, France.

Recent technological advances coupled with our improved understanding of the molecular and cellular mechanisms associated with cancer development have enabled better overall patient care. Among the newly identified biomarkers such as circulating tumor DNA or circulating tumor cells, hPG (circulating progastrin) that is easy to detect and quantify by a simple ELISA assay has the potential to become a new routine clinical tool in oncology if on-going studies validated its utility. Indeed, on the one hand, hPG was found in the blood of patients with different tumors (colorectal, pancreatic, liver, lung, stomach, kidney cancers) at a significantly higher concentration than in healthy donors.

Role of the TATA-box binding protein (TBP) and associated family members in transcription regulation.

Gene 2022 May 18:146581. Epub 2022 May 18.

Department of Cell Biology, Center for Research and Advanced Studies of the National Polytechnic Institute, Av. Instituto Politécnico Nacional 2508, Col. San Pedro Zacatenco, C.P. 07360 Mexico City, Mexico. Electronic address:

The assembly of transcription complexes on eukaryotic promoters involves a series of steps, including chromatin remodeling, recruitment of TATA-binding protein (TBP)-containing complexes, the RNA polymerase II holoenzyme, and additional basal transcription factors. This review describes the transcriptional regulation by TBP and its corresponding homologs that constitute the TBP family and their interactions with promoter DNA. The C-terminal core domain of TBP is highly conserved and contains two structural repeats that fold into a saddle-like structure, essential for the interaction with the TATA-box on DNA. Read More

Differential Analyte Derivatization Enables Unbiased MALDI-TOF-based High-Throughput Screening: A Proof-of-Concept Study for the Discovery of Catechol-O-methyltransferase Inhibitors.

SLAS Discov 2022 May 18. Epub 2022 May 18.

Drug Discovery Sciences, Boehringer Ingelheim Pharma GmbH & Co. KG, Biberach an der Riß, Germany. Electronic address:

Recent advances in label-free high-throughput screening via matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry (MS) offer unprecedented opportunities for the identification of novel chemical starting points in target-based drug discovery. A clear advantage of the technology is the possibility for label-free, direct quantification of analytes with high precision and robustness. Here we have expanded the range of analytes and biology that can be addressed via MALDI-TOF HTS, by developing a method based on post-reaction pyrylium-based derivatization to detect 3-methoxytyramine, the physiological enzyme product of the catechol-O-methyltransferase (COMT) enzyme.

New Directions in Phosphorus Management in Dialysis.

J Ren Nutr 2022 May 18. Epub 2022 May 18.

Professor of Clinical Medicine, Renal Electrolyte and Hypertension Division, University of Pennsylvania, Philadelphia, PA, USA.

Current phosphate management strategies in end-stage renal disease (dietary phosphate restriction, dialysis, and phosphate binders) are inadequate to maintain target phosphate levels in most patients. Dietary phosphate restriction is challenging due to "hidden phosphates" in processed foods, and dialysis and phosphate binders are insufficient to match average dietary phosphate intake. As phosphate binders must be taken with each meal, patients need to ingest many, large pills several times a day, negatively impacting quality of life. Read More

Racism and Perinatal Health Inequities Research: Where we have been and where we should go.

Am J Obstet Gynecol 2022 May 18. Epub 2022 May 18.

Department of Obstetrics and Gynecology, University of Utah Health, Salt Lake City, Utah.

For over a century, substantial racial and ethnic inequities in perinatal health outcomes have persisted despite technical clinical advances and changes in public health practice that lowered the overall incidence of morbidity. Race is a social construct and not an inherent biological or genetic reality; therefore, racial differences in health outcomes represent the consequences of structural racism, or the inequitable distribution of opportunities for health along racialized lines. Clinicians and scientists in obstetrics and gynecology have a responsibility to work to eliminate health inequities for Black, Brown, and Indigenous birthing people, and fulfilling this responsibility requires actionable evidence from high quality research.

Using Precision Medicine for the Diagnosis and Treatment of Viral Pneumonia.

Adv Ther 2022 May 21. Epub 2022 May 21.

Department of Medicine, Northeast Ohio Medical University, Rootstown, OH, USA.

The COVID-19 pandemic has drawn considerable attention to viral pneumonia from clinicians, public health authorities, and the general public. With dozens of viruses able to cause pneumonia in humans, differentiating viral from bacterial pneumonia can be very challenging in clinical practice using traditional diagnostic methods. Precision medicine is a medical model in which decisions, practices, interventions, and therapies are adapted to the individual patient on the basis of their predicted response or risk of disease.

Track and trace: how soil labelling techniques have revealed the secrets of resource transport in the arbuscular mycorrhizal symbiosis.

Mycorrhiza 2022 May 21. Epub 2022 May 21.

The Waite Research Institute and School of Agriculture, Food and Wine, The University of Adelaide, PMB 1, Glen Osmond, South Australia, 5064, Australia.

Arbuscular mycorrhizal (AM) fungi colonise plant roots, and by doing so forge the 'mycorrhizal uptake pathway(s)' (MUP) that provide passageways for the trade of resources across a specialised membrane at the plant-fungus interface. The transport of nutrients such as phosphorus (P), nitrogen and zinc from the fungus, and carbon from the plant, via the MUP have mostly been quantified using stable or radioactive isotope labelling of soil in a specialised hyphae-only compartment. Recent advances in the study of AM fungi have used tracing studies to better understand how the AM association will function in a changing climate, the extent to which the MUP can contribute to P uptake by important crops, and how AM fungi trade resources in interaction with plants, other AM fungi, and friend and foe in the soil microbiome.
