Expression of Semaphorin3E/PlexinD1 in human airway smooth muscle cells of patients with COPD.

Am J Physiol Lung Cell Mol Physiol

December 2024

Department of Immunology, Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, Manitoba, Canada.

Semaphorin3E (Sema3E) is a member of axon guidance proteins that have emerged recently as essential regulators of cell migration and proliferation. It binds to PlexinD1 with high affinity and is expressed in different cell types, including immune, cancer, and epithelial cells. Recent work in our lab has revealed a critical immunoregulatory role of Sema3E in experimental allergic asthma; however, its role in chronic obstructive pulmonary disease (COPD) remains unclear.

Research Group in Sports Biomechanics (GIBD), Department of Physical Education and Sports, Faculty of Physical Activity and Sport Sciences, University of Valencia, C/Gascó Oliag, 3, 46010, Valencia, Spain.

Bicycle set-up dimensions and cycling kinematic data are important components of bicycle fitting and cyclist testing protocols. However, there are no guidelines on how bicycles should be measured and how kinematic data should be collected to increase the reliability of outcomes. This article proposes a consensus regarding bicycle set-up dimensions and recommendations for collecting cycling-related kinematic data.

Human activities related to agriculture and industrial development result in the emission of different types of pollutants in the environment. The phytosanitary pressure depends on the time of the year, the type of habitat, and the used treatments. Wildlife, particularly ungulates, can be exposed to pesticides and trace metals through their herbivorous diet directly impregnated by the environmental contamination.

Background: The aging global population forecasts a significant rise in severe trauma cases among individuals aged 65 and above. Frailty emerges as a paramount predictor of post-traumatic outcomes, surpassing age and trauma severity indices. Despite this, scant attention is given to the trajectory of elderly patients post-intensive care unit (ICU) stay following severe trauma, justifying this study.

The diversity of the plant biomass available on earth makes plants an exceptional resource for replacing fossil resources in green chemistry, bioenergy and biobased materials. For numerous applications, and especially the high-tech ones (building block molecules, high-power bioenergy, additive manufacturing of biobased materials), the macrostructure assemblies of the plant biomass often need to be first broken down into a fine powder. This can be achieved by dry fractionation process combining comminution and sorting steps.

The reduction of titanocene dichloride CpTiCl with lanthanide metals has led to the discovery of a surprising lanthanide effect: while with most lanthanides, a divalent [CpTi] equivalent was obtained, the use of samarium or ytterbium only led to the reduction to trivalent [CpTiCl]-type complexes, including the structurally characterized heterobimetallic complex [CpTi(μ-Cl)SmCl(THF)]. These results were corroborated by reactivity studies (alkyne coupling and radical reactions), EPR spectroscopy and electrospray mass spectrometry, providing new insights into the reduction chemistry of lanthanide metals.

Background: Obstructive sleep apnea (OSA) is associated with the impairment of a range of cognitive functions. Whether treatment with continuous positive airway pressure (CPAP) improves these cognitive functions is still a matter of debate.

Methods: We performed a systematic review and meta-analysis of randomized controlled trials (RCTs) that included OSA patients (apnea hypopnea index, AHI >10/h), naive to CPAP treatment, with a cognitive assessment before and after CPAP initiation.

Pesticide use increases annually, and Brazil is the world's largest consumer. However, unlike the European Union (EU), there is no established limit value for pesticide mixtures in drinking water, and therefore the concentration of pesticides can reach 3354 times the EU limit. Thus, determining the risk of exposure to pesticide mixtures and their main metabolites is challenging and requires the use of alternative methods.

Article Synopsis
  • Delays in breast cancer detection and treatment can lead to higher mortality rates, making organized breast cancer screenings (OBCS) crucial, but global participation has been low, especially during the COVID-19 pandemic.
  • A study analyzed 6,282 women in France invited to OBCS in 2020, categorizing their responses based on when they underwent mammography after their invitation: promptly, late, or not at all.
  • The results showed that younger women and those with less frequent gynecological and colorectal cancer screenings were less likely to attend, while women with higher education and those from disadvantaged areas tended to attend late.

In situ imaging of LPMO action on plant tissues.

Carbohydr Polym

November 2024

INRAE, UR 1268 BIA, 44316 Nantes, France. Electronic address:

Lytic polysaccharide monooxygenases (LPMOs) are copper-dependent enzymes that oxidatively cleave recalcitrant polysaccharides such as cellulose. Several studies have reported LPMO action in synergy with other carbohydrate-active enzymes (CAZymes) for the degradation of lignocellulosic biomass but direct LPMO action at the plant tissue level remains challenging to investigate. Here, we have developed a MALDI-MS imaging workflow to detect oxidised oligosaccharides released by a cellulose-active LPMO at cellular level on maize tissues.

November 2024

EMMA Research Group, Centre d'Analyses et de Recherche, Faculty of Sciences, Université Saint-Joseph, Beirut, Lebanon; Climate and Atmosphere Research Center (CARE-C), The Cyprus Institute, Nicosia, Cyprus. Electronic address:

Traffic emissions are an important source of air pollution worldwide, but in the Middle East, this problem is exacerbated by weak or no enforcement of emission regulations. Comprehensive measurements of fine PM emission factors (EFs) from road transport in the region have not yet been conducted, but such data are necessary for quantitative assessments of the health impact of transport emissions in the region. To address this need, PM samples collected inside the Salim Slam tunnel in Beirut, Lebanon were analyzed for carbonaceous matter (organic carbon (OC) and elemental carbon (EC)), water-soluble ions, elements, and selected organic compounds.

There is growing interest in limiting the use of fungicides and implementing innovative, environmentally friendly strategies, such as the use of beneficial bacteria-triggered immunity, to protect grapevines from natural pathogens. Therefore, we need rapid and innovative ways to translate the knowledge of the molecular mechanisms underlying the activation of grapevine defenses against pathogens to induced resistance. Here, we have implemented an minimally invasive approach to study the interaction between plants and beneficial bacteria based on metabolic signatures.

Article Synopsis
  • Transthyretin amyloid cardiomyopathy (ATTR-CM) can complicate conditions like heart failure and aortic stenosis (AS), especially in older adults, but its prevalence among AS patients undergoing transaortic valve implantation (TAVI) is not well-studied.
  • A study screening 100 TAVI patients showed an ATTR-CM prevalence of 7%, predominantly in older males, with specific electrocardiographic and structural heart changes noted in those positive for ATTR-CM.
  • One-year survival rates for patients with positive ATTR-CM tests were similar to those with isolated AS, emphasizing the need for ongoing monitoring and further research on long-term outcomes in ATTR-CM patients post-TAVI.
