Use of recombinant factor VIIa (rFVIIa, NovoSeven in patients with congenital FVII deficiency has been reported for the prophylactic management of surgical bleeding and for the treatment of acute bleeding episodes. Because of its short half-life, the use of rFVIIa on a regular prophylactic regimen has not been routinely adopted. In this report, we describe our successful experience with rFVIIa prophylaxis in preventing recurrent target joint bleeding in a severely FVII-deficient adolescent.

Objective: Emicizumab promotes efficacious hemostasis in persons with hemophilia A persons with hemophilia A with and without inhibitors. Primary analyses of real-world data and clinical trials have shown emicizumab efficacy and safety; however, long-term data are limited.
Methods: This retrospective study was conducted to assess real-world long-term outcomes of pediatric patients on emicizumab in our hemophilia center between the period of February 2018 and September 2023.

Activated keratinocytes play a crucial role in skin inflammation through the production of multiple inflammatory mediators; however, little is known about cytokine secretion by activated keratinocytes in dogs. This study aimed to investigate the effects of the Th1 and Th2 types of cytokines on the production of keratinocyte-derived inflammatory mediators. Canine progenitor epidermal keratinocytes (CPEKs) were incubated with canine recombinant IL-4, IL-13, an IL4/IL13 mixture, IFN-γ, TNF-α, or an IFN-γ/TNF-α mixture for 24 h following 100% confluency.

Background/objectives: Adenoviral vector-based vaccines against COVID-19 rarely cause vaccine-induced immune thrombocytopenia and thrombosis (VITT), a severe adverse reaction caused by IgG antibodies against platelet factor 4 (PF4). To study VITT, patient samples are crucial but have become a scarce resource. Recombinant antibodies (rAbs) derived from VITT patient characteristic amino acid sequences of anti-PF4 IgG are an alternative to study VITT pathophysiology.

Antimonide laser diodes, with their high performance above room temperature, exhibit significant potential for widespread applications in the mid-infrared spectral region. However, the laser's performance significantly degrades as the emission wavelength increases, primarily due to severe quantum-well hole leakage and significant non-radiative recombination. In this paper, we put up an active region with a high valence band offset and excellent crystalline quality with high luminescence to improve the laser's performance.
