Additive Manufacturing (AM) was evaluated as a promising technology for constructing photocatalytic reactors due to its inherent ability to produce complex geometries with high precision and customization. In this work, a 3D structure was designed to achieve a good light distribution inside a cylindrical batch reactor and printed using the stereolithography (SLA) technique. A hybrid material composed of a commercial photoreactive resin (Formlabs Clear V4) and the benchmark photocatalyst TiO P25 Evonik (1 wt%) was prepared and characterized by scanning electron microscopy (SEM) and rheological and mechanical methods.

Despite significant strides in improving cancer survival rates, the global cancer burden remains substantial, with an anticipated rise in new cases. Immune checkpoints, key regulators of immune responses, play a crucial role in cancer evasion mechanisms. The discovery of immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 has revolutionized cancer treatment, with monoclonal antibodies (mAbs) becoming widely prescribed.

Introduction: Transvaginal retropubic (TVT-R) and transobturator (TVT-O) midurethral slings are the main surgical options for stress urinary incontinence (SUI). Surgical indications for each of them are defined by clinical and history presentation. These techniques play a particular role in SUI recurrence after a previous urinary incontinence surgery, although there are few studies comparing their efficacy.

Antibiotics are central to managing airway infections in cystic fibrosis (CF), yet current treatments often fail due to the presence of biofilms, settling down the need for seeking therapies targeting biofilms. This study aimed to investigate the antibiofilm activity of aspartic acid and its potential as an adjuvant to tobramycin against biofilms formed by mucoid and small colony variant (SCV) tobramycin tolerant strain. We assessed the effect of aspartic acid on both surface-attached and suspended biofilms within CF artificial mucus and investigated the synergistic impact of combining it with non-lethal tobramycin concentrations.

Department of Internal Medicine, Trofa Saúde Hospital Privado em Gaia, Vila Nova de Gaia, Portugal.

Autoinflammatory bone disorders (ABDs) are characterized by sterile bone inflammation stemming from dysregulated innate immune responses. This review focuses on the occurrence of sterile osteomyelitis in ABDs and related diseases, notably chronic nonbacterial osteomyelitis (CNO) and its sporadic and monogenic forms, such as deficiency of the interleukin-1 (IL-1) receptor antagonist, Majeed syndrome, CNO related to mutation, and pyogenic arthritis, pyoderma gangrenosum, and acne (PAPA syndrome). Additionally, other autoinflammatory disorders (AIDs) are discussed, including classical periodic fever syndromes (e.

A strong n-type perovskite layer is crucial in achieving high open-circuit voltage (V) and power conversion efficiency (PCE) in the p-i-n solar cells, as the weak n-type perovskites result in a loss of V, and the p-type perovskites contain numerous electron traps that cause the severe carrier recombination. Here, three types of perylene diimide (PDI) based small molecule dopants with different dimensions, including 1D-PDI, 2D-PDI, and 3D-PDI are designed, to produce heavier n-type perovskites. The PDI-based molecules with Selenium atoms have a strong electron-donating ability, effectively enlarging the quasi-Fermi level splitting within the perovskites.
