Anti-ELANE polyclonal antibody [Biotin]

Background. Severe congenital neutropenia (SCN) is an immunodeficiency characterized by disturbed myelopoiesis and an absolute neutrophil count (ANC) <0.5 x 10(9)/L. SCN is also a premalignant condition; a significant proportion of patients develop myelodysplastic syndrome or leukemia (MDS/L). Allogeneic hematopoietic stern cell transplantation (HSCT) is the only curative treatment for SCN. Procedure. Since 2004, eight HSCT have been performed in seven patients at our center. The indications were transformation to MDS/L (n = 2), granulocyte colony-stimulating factor receptor (CSF3R) mutation(s) (n = 2), granulocyte colony-stimulating factor (G-CSF) resistance (n = 2), and at the patient's own request (n = 1). Results. The mean age at transplantation was 13 years (2.8-28 years) (mean follow-up 32 months, range 21-60). Three patients harbored ELANE mutations, three HAX1 mutations, and in one patient no causative mutation was identified. Two of the ELANE mutations were novel mutations. Three patients initially received myeloablative conditioning and four had reduced intensity conditioning (RIC). Three grafts were from HLA-identical siblings, three from matched unrelated donors and two were cord blood units. Engraftment occurred in all patients. Two of seven (29%) patients. died; both had MDS/L and both were among the three that underwent myeloablative conditioning. One patient has chronic GVHD 2 years post-transplant. Conclusions. The role of HSCT should be explored further in patients with SCN. In particular, the influence of the conditioning regime needs to be evaluated in a larger cohort of patients.

More and more states are permitting same-sex unions to be celebrated, which will likely result in an increase in the number of individuals claiming that they are precluded by conscience from providing goods or services to such families. While the First Amendment to the United States Constitution provides great protection to religious belief, it provides much less protection to conscience-based conduct in violation of nondiscrimination statutes, especially when such refusals of conscience are in a commercial context. This Article discusses a variety of cases that are often thought to implicate matters of conscience compelled speech, symbolic conduct, conscientious objection as well as several unemployment benefits and right of association cases. While these cases might be interpreted in a number of ways, they nonetheless seem to provide relatively little protection to conscience-based refusals to engage in allegedly symbolic activities that themselves might be interpreted in a number of ways. After providing an analysis of existing constitutional protections, the Article focuses on Elane Photography v. Willock, explaining how the case should be decided in light of existing constitutional guarantees as they have been explained by the Court. The Article concludes that were the Court to ignore the current jurisprudence and find such conscience-based actions protected under the Federal Constitution, the Court would thereby create an exception that was difficult if not impossible to cabin, which would lead to a variety of regrettable consequences.
