Article Synopsis
  • Heterozygous STAT1 Gain-of-Function mutations are linked to chronic mucocutaneous candidiasis (CMC) and can lead to various immune disorders like autoimmune diseases and malignancies, with JAK inhibitors showing promise in treatment.
  • In a study of five Taiwanese patients, two new STAT1 GOF mutations were discovered, revealing clinical symptoms like CMC and autoimmunity, along with notable changes in immune cell types.
  • This research provides key insights into the immune dysregulation seen in STAT1 GOF patients and suggests that baricitinib is safe and effective for treatment, although further studies are needed to understand the underlying mechanisms driving these immune changes.

The development of facile, efficient synthesis method to construct low-cost and high-performance single-atom catalysts (SACs) for oxygen reduction reaction (ORR) is extremely important, yet still challenging. Herein, an atomically dispersed N, S co-doped carbon with abundant vacancy defects (NSC-vd) anchored Fe single atoms (SAs) is reported and a vacancy defects inductive effect is proposed for promoting electrocatalytic ORR. The optimized catalyst featured of stable Fe─N S active sites exhibits excellent ORR activity with high turnover frequency and mass activity.

Confirmatory tests for diagnosis of primary aldosteronism (PA) play an important role in sparing patients with a false-positive aldosterone-to-renin ratio (ARR) screening test from undergoing invasive subtyping procedures. We recommend that patients with a positive ARR test should undergo at least one confirmatory test to confirm or exclude the diagnosis of PA before directly proceeding to subtype studies, except for patients with significant PA phenotypes, including spontaneous hypokalemia, plasma aldosterone concentration >20 ng/dL plus plasma renin activity below a detectable level. Although a gold standard confirmatory test has not been identified, we recommend that saline infusion test and captopril challenge test, which were widely used in Taiwan.

Directed self-assembly of block copolymers is a key enabler for nanofabrication of devices with sub-10 nm feature sizes, allowing patterning far below the resolution limit of conventional photolithography. Among all the process steps involved in block copolymer self-assembly, solvent annealing plays a dominant role in determining the film morphology and pattern quality, yet the interplay of the multiple parameters during solvent annealing, including the initial thickness, swelling, time, and solvent ratio, makes it difficult to predict and control the resultant self-assembled pattern. Here, machine learning tools are applied to analyze the solvent annealing process and predict the effect of process parameters on morphology and defectivity.

Article Synopsis
  • A study was conducted to determine the role of MPO-ANCA titers as a prognostic factor for patients with active ANCA-associated vasculitis (AAV).
  • The research included 97 inpatients and compared high ANCA titer patients (over four times the normal value) to those with low titers, revealing that high titer patients had significantly worse initial renal function and lower 2-year renal survival rates.
  • The findings suggest that higher MPO-ANCA titers at diagnosis could predict poor renal outcomes, emphasizing the importance of monitoring these levels in AAV patients.

Two-dimensional transition metal dichalcogenide (TMD) materials, albeit promising candidates for applications in electronics and optoelectronics, are still limited by their low electrical mobility under ambient conditions. Efforts to improve device performance through a variety of routes, such as modification of contact metals and gate dielectrics or encapsulation in hexagonal boron nitride, have yielded limited success at room temperature. Here, we report a large increase in the performance of TMD field-effect transistors operating under ambient conditions, achieved by engineering the substrate's surface morphology.
