This article reports the force spectroscopy investigation of interactions between lipopolysaccharides (LPSs) of two species from Yersinia genus and complementary (or heterologous) monoclonal antibodies (mAbs). We have obtained the experimental data by optical trapping on the "sensitized polystyrene microsphere - sensitized glass substrate" model system at its approach - retraction in vertical plane. We detected non-specific interactions in low-amplitude areas on histograms mainly due to physicochemical properties of abiotic surface and specific interactions in complementary pairs "antigen - antibodies" in high-amplitude areas (100-120 pN) on histograms. The developed measurement procedure can be used for detection of rupture forces in other molecular pairs.

Our current prospective cross-sectional study aimed to investigate the effect of anti-vascular endothelial growth factor (VEGF) drugs used in the treatment of retinopathy of prematurity on retinal maturation and persistent avascular retina (PAR). Retinal imaging was performed with Optos confocal laser ophthalmoscopy for 100 patients aged 4 to 8 years who were screened and treated for retinopathy of prematurity (ROP) during the neonatal period. The ROP examination findings (stage and zone) and treatment history (age in weeks at time of treatment and anti-VEGF drug used) from the neonatal period were reviewed.

Multiple myeloma (MM), a hematological malignancy which affects the monoclonal plasma cells in the bone marrow, is in rising incidence around the world, accounting for approximately 2 % of newly diagnosed cancer cases in the US, Australia, and Western Europe. Despite the progress made in the last few years in the available therapeutic options (e.g.

Brentuximab vedotin (BV)-bendamustine (90 or 120 mg/m2 day 1 and 2) every 28 days is an effective treatment for relapsed/refractory Hodgkin lymphoma (R/R HL) but associated to high toxicity especially for elderly patients. We conducted in St Louis Hospital, Paris, between 2015 and 2021 a retrospective single-center analysis of 44 patients with R/R HL treated with one-day BV-bendamustine (120 mg/m2) every 21 days. Sixteen percent of patients were ≥ 60 years old (yo).

Purpose: This study presents an indirect comparison of the effectiveness and safety of faricimab versus other treatment options for DME.
Purpose: This study evaluates the efficacy of intravitreal injections (IVI) of faricimab in patients with neovascular age-related macular degeneration (nAMD) and retinal pigment epithelium detachment (RPED) resistant to other anti-VEGF agents.
Material And Methods: The study included 61 patients (61 eyes) with nAMD previously treated with aflibercept and/or brolucizumab IVIs. Three groups were formed: group 1 received aflibercept IVI (32 eyes), group 2 received brolucizumab IVI (14 eyes), and group 3 received aflibercept followed by brolucizumab IVI (15 eyes).
