Purpose: SLM 3D printing technology is one of the most widely used implant-making technologies. However, the surfaces of the implants are relatively rough, and bacteria can easily adhere to them; increasing the risk of postoperative infection. Therefore, we prepared a near-infrared photoresponsive nano-TiO coating on the surface of an SLM 3D-printed titanium alloy sheet (Ti6Al4V) via a hydrothermal method to evaluate its antibacterial properties and biocompatibility.

In the field of implantology, peri-implantitis is still a common complication of implant failure. Similar to periodontal disease, this kind of pathological condition is characterized by inflammation of the tissues surrounding dental implants or fillings. The sources of infection have been shown to be chronic periodontitis and poor maintenance of the communion.

Background: Increased risk of HIV acquisition during pregnancy and lactation among women is evident, necessitating their inclusion in the evaluation of new HIV prevention interventions. Pregnant and postpartum women specifically face challenges with oral PrEP associated with stigma, and the burden of using other tablets. Long-acting products may address challenges related to oral PrEP, however, there is limited data on product-specific preferences and acceptability among pregnant and lactating women.

Despite the unique properties of clay nanocomposites for cardiovascular applications, there are few data on the hemocompatibility of these nanomaterials. This study represents the first comprehensive investigation of the hemo/biocompatibility of clay nanocomposites . Nanocomposite coatings of polylactic acid (PLA)-polyethylene glycol (3 wt %)-Cloisite20A nanoclay (3 wt %) were produced using electrospraying technique as potential drug-eluting stent (DES) coatings.

Ebola virus (EBOV) causes severe disease in humans, with mortality as high as 90%. The small-molecule antiviral drug remdesivir (RDV) has demonstrated a survival benefit in EBOV-exposed rhesus macaques. Here, we characterize the efficacy of multiple intravenous RDV dosing regimens on survival of rhesus macaques 42 days after intramuscular EBOV exposure.
