Nonlinear mid-infrared meta-membranes.

Nanophotonic structures have shown promising routes to controlling and enhancing nonlinear optical processes at the nanoscale. However, most nonlinear nanostructures require a handling substrate, reducing their application scope. Due to the underwhelming heat dissipation, it has been a challenge to evaluate the nonlinear optical properties of free-standing nanostructures.

Functional annotation of the Hippo pathway somatic mutations in human cancers.

The Hippo pathway is commonly altered in cancer initiation and progression; however, exactly how this pathway becomes dysregulated to promote human cancer development remains unclear. Here we analyze the Hippo somatic mutations in the human cancer genome and functionally annotate their roles in targeting the Hippo pathway. We identify a total of 85 loss-of-function (LOF) missense mutations for Hippo pathway genes and elucidate their underlying mechanisms.

Two-photon absorption in silicon using the real density matrix approach.

Two-photon absorption in indirect gap semiconductors is a frequently encountered, but not well-understood phenomenon. To address this, the real-density matrix approach is applied to describe two-photon absorption in silicon through the excitonic response to the interacting fields. This approach produces an analytical expression for the dispersion of the two-photon absorption coefficient for indirect-gap materials and can be used to explain trends in reported experimental data for bulk silicon both old and new with minimal fitting.

Impact of Elevated Serum Triglycerides on Children with Acute Recurrent or Chronic Pancreatitis from INSPPIRE-2.

Objective: To determine if mild-moderate hypertriglyceridemia (HTG) is associated with increased development of chronic pancreatitis (CP) or pancreatitis-associated complications in children with acute recurrent or CP.

Study Design: Longitudinal data from the INternational Study group of Pediatric Pancreatitis: In search for a cuRE-2 (INSPPIRE-2) cohort of children with acute recurrent or CP (n = 559) were analyzed. Subjects were divided into normal triglycerides (<150 mg/dL; 1.

Immunotherapy in Head and Neck Cancer: Treatment Paradigms, Future Directions, and Questions.

The use of immunotherapy in head and neck squamous cell carcinoma (HNSCC)has increased treatment options for patients who may not be candidates for traditional cytotoxic chemotherapy. Recent studies have resulted in the approval of immunotherapy in the first and second line setting for recurrent/metastatic disease. Various combinations of immunotherapy with targeted therapies, monoclonal antibodies, or human papilloma virus vaccines are also being studied in recurrent/metastatic disease.
