The search for novel material platforms that could spur the progress by providing new functionalities for solving the outstanding technological problems is however still active. Any physical property presenting two distinct energy states that can be found in a long-lived superposition state can serve as a quantum bit (qubit), the basic information processing unit in quantum technologies.

Enhanced production of jet fuel precursors via furfural/cyclopentanone aldol condensation by synergistic pairing TiO with nano-ZSM-5 zeolite.

Aldol condensation of biomass-derived compounds offers a sustainable route to jet fuel precursors. This study explores catalysts based on nanocrystalline ZSM-5 zeolite (n-ZSM-5) modified with various metals (Ca, Mg, Sn, Ti, Zr) for the aldol condensation of furfural (FFL) and cyclopentanone (CPO). While both reactants can enter the ZSM-5 micropores, the resulting C10 (FC) and C15 (FC) adducts are too large to be formed within or to exit the microporosity, being instead produced over the external acid sites.

Amphotericin B Ocular Films for Fungal Keratitis and a Novel 3D-Printed Microfluidic Ocular Lens Infection Model.

Fungal keratitis (FK), a severe eye infection that leads to vision impairment and blindness, poses a high risk to contact lens users, and remains the most common underpinning fungal pathogen in temperate climates. Patients are initially treated empirically (econazole 1% drops hourly for 24-48 h), and if there is no response, amphotericin B (AmB) 0.15% eye drops (extemporaneously manufactured to be stable for a week) are the gold-standard treatment.

Heparin-azithromycin microparticles show anti-inflammatory effects and inhibit SARS-CoV-2 and bacterial pathogens associated to lung infections.

Pulmonary infections are a leading cause of morbidity and mortality worldwide, a situation exacerbated by the COVID-19. Azithromycin (AZM) is used orally to treat pulmonary infections due to its ability to accumulate in lung tissues and immune cells after oral administration. Sulfated polysaccharides, such as heparin, are known to inhibit SARS-CoV-2 entry.

Population monitoring and conservation implications of intra- and interspecific nest occupation rates in swallows.

With the exception of a few groups of birds, such as large raptors and colonial seabirds, direct counts of nests cannot be conducted over very large areas for most of the abundant and widely distributed species, and thus indirect methods are used to estimate their relative abundances and population sizes. However, many species of the Family Hirundinidae (swallows and martins) build their mud nests in discrete, predictable and accessible sites, which are reused across years. Therefore, the direct count of active nests could constitute a reliable method for estimating breeding population sizes and their changes at large spatial and temporal scales.

Non-recyclable municipal solid waste characterization and pyrolysis for energy recovery.

European regulations require that by 2030 waste suitable for recycling, material recovery, or energy recovery will no longer be allowed to end up in landfills. Material composition in non-recyclable MSW bins dictates which valorization measures could be implemented. This study examines 32 non-recyclable MSW bins in the Getafe municipality (Spain).

TIMP1 mediates astrocyte-dependent local immunosuppression in brain metastasis acting on infiltrating CD8+ T cells.

Immunotherapies against brain metastases have shown clinical benefits when applied to asymptomatic patients, but they are largely ineffective in symptomatic cases for unknown reasons. Here we dissect the heterogeneity in metastasis-associated astrocytes using scRNAseq and report a population that blocks the antitumoral activity of infiltrating T cells. This pro-tumoral activity is mediated by the secretion of TIMP1 from a cluster of pSTAT3+ astrocytes that acts on CD63+ CD8+ T cells to modulate their function.

Dendritic ZSM-5 zeolites as highly active catalysts for the valorization of monoterpene epoxides.

Dendritic ZSM-5 zeolites were investigated in the isomerization of monoterpene epoxides, including limonene-1,2-epoxide (LE), α-pinene epoxide, and β-pinene epoxide, which yields high-value compounds used in fragrances, cosmetics, and pharmaceuticals. The fresh catalysts were thoroughly characterized using XRD, Ar physisorption, pyridine-FTIR, TEM, FTIR/DTBPyr, and Al MAS NMR. In comparison with conventional and hierarchical ZSM-5 materials, the dendritic zeolite with a crystallization time of 4 days (d-ZSM-5/4d) was the most active material, with a turnover frequency value of 4.

Low dose TamOxifen and LifestylE changes for bReast cANcer prevention (TOLERANT study): Study protocol of a randomized phase II biomarker trial in women at increased risk for breast cancer.

Background: Breast Cancer (BC) prevention strategies range from lifestyle changes such as increasing physical activity and reducing body weight to preventive drugs like tamoxifen, known to reduce BC incidence in high-risk women. Sex Hormone Binding Globulin (SHBG) is related to BC risk due to its ability to bind circulating estradiol at high affinity and to regulate estradiol action. A study protocol is presented based on the assessment of the effect of different interventions such as tamoxifen at 10 mg every other day (LDT), intermittent caloric restriction (ICR) two days per week, lifestyle intervention (LI, step counter use) and their combination on the modulation of SHBG and several other biomarkers associated to BC.

Drug and biomarker tissue levels in a randomized presurgical trial on exemestane alternative schedules.

The drug's activity at the target tissue could help to define the minimal effective dose to promote cancer preventive therapy. Here we present exemestane and sex hormone concentrations within breast tissue from a presurgical study of alternative exemestane schedules. Postmenopausal women candidates for breast surgery for estrogen receptor-positive breast cancer were randomly assigned to exemestane 25 mg once daily (QD), 25 mg 3 times/week (TIW), or 25 mg per week (QW) for 4-6 weeks before surgery.

Leveraging 3D-printed microfluidic micromixers for the continuous manufacture of melatonin loaded SNEDDS with enhanced antioxidant activity and skin permeability.

Vesicants are chemical warfare agents (CWAs) capable of causing severe skin damage and systemic toxicity. Melatonin, known for its anti-inflammatory and antioxidant properties, can mitigate the effects of these agents. Self-nano-emulsifying drug delivery systems (SNEDDS) containing a high melatonin concentration (5 %, 50 mg/g) were optimized using a quality-by-design approach from biocompatible, non-irritant excipients with a particle size of about 100 nm.
