Article Synopsis
  • State-of-the-art oxides and sulfides are key candidates for solid-state electrolytes due to their high Li-ion conductivity and electrochemical stability, but emerging halides show promise because of their low Li migration energy and mechanical advantages.
  • Mechanochemical synthesis has allowed for the creation of LiAlI for the first time, and the synthesized LiAlBr exhibited the highest conductivity at room temperature, while LiAlCl showed better performance at elevated temperatures.
  • Modeling suggests that the transport mechanism for Li-ions in these compounds is influenced by halide properties and the movements of complex anions.

Given the inherent performance limitations of intercalation-based lithium-ion batteries, solid-state conversion batteries are promising systems for future energy storage. A high specific capacity and natural abundancy make iron disulfide (FeS ) a promising cathode-active material. In this work, FeS nanoparticles were prepared solvothermally.

Hereditary angioedema (HAE) is a genetically heterogeneous disease that is characterized by recurrent skin swelling, abdominal pain attacks, and potentially life-threatening upper airway obstruction. The two classic types, HAE types I and II, are both caused by mutations in the complement C1 inhibitor (SERPING1) gene resulting either in a quantitative or a qualitative deficiency of C1 inhibitor. In so-called HAE type III, in contrast, patients show normal C1 inhibitor measurements in plasma ('HAE with normal C1 inhibitor').

Meningococcal disease is caused by Neisseria meningitidis which is associated with high morbidity and mortality. Recurrences of meningococcal infection have been observed in patients with terminal complement component defects, because of the inefficient formation of the lytic membrane attack complex (MAC), C5b-9. Complement component C7 is one of the five plasma proteins to form the MAC.

Purpose: A new type of hereditary angioedema was described recently. It was characterized by recurrent bouts of angioedema in various organs and normal C1 inhibitor and was observed mainly in women. Our aim was to conduct a detailed study of the clinical features of this condition.

Hereditary angioedema is characterized by recurrent skin swelling, abdominal pain attacks, and potentially life-threatening upper airway obstruction. The two classic types are both caused by mutations within the complement C1 inhibitor gene. A recently described new type does not show a deficiency of C1 inhibitor and affects almost exclusively women.

We have identified nonsense mutations in the gene CDSN (encoding corneodesmosin) in three families suffering from hypotrichosis simplex of the scalp (HSS; OMIM 146520). CDSN, a glycoprotein expressed in the epidermis and inner root sheath (IRS) of hair follicles, is a keratinocyte adhesion molecule. Truncated CDSN aggregates were detected in the superficial dermis and at the periphery of hair follicles.

Purpose: Recurrent angioedema, characterized by skin swelling, colicky attacks of abdominal pain, and life-threatening laryngeal edema, can be either hereditary or acquired. According to anecdotal reports, it may be associated with use of oral contraceptives and hormone replacement therapy. We investigated potential interactions between these medications and various types of recurrent angioedema in a large cohort of women.
