Published: March 2013

In this Letter we demonstrate frequency conversion in the single-photon regime through Bragg-scattering four-wave mixing with near-unit efficiency in a 750 m long commercially available dispersion-engineered highly nonlinear fiber, where all photons and pump laser frequencies are in the low-loss telecommunications band. We achieve 99.1%±4.9% downconversion and 98.0%±5.0% upconversion of photons by 12 nm using a weak coherent state with an average input of 0.27 photons per detection gate window.

Aim: To study the adverse reactions that develop as a result of complex antibiotic therapy in patients with non-tuberculous lung mycobacterial (NTML) and to determine methods for their elimination without compromising the effectiveness of NTML treatment.

Materials And Methods: Examined 147 patients with confirmed NTML, for which they received treatment in accordance with the results of drug susceptibility of the pathogen. Before and during treatment, a study of clinical, biochemical blood tests, urinalysis, electrocardiogram, external respiration function, ultrasound of the abdominal organs and kidneys was performed.

Background: The equivalence between left upper lobectomy (LUL) and left upper tri-segmentectomy (LUTS) for stage I left upper non-small cell lung cancer (NSCLC) remains unclear. This study compares the perioperative and oncological outcomes of LUL and LUTS in this patient population.

Methods: This study included patients who underwent LUL or LUTS at West China Hospital of Sichuan University and Sichuan ShangJin Hospital between August 2018 and November 2023.

Background: There is ongoing debate surrounding the optimal therapeutic strategy for hepatocellular carcinoma (HCC) patients achieving complete response (CR) after conversion therapy. This meta-analysis compares the prognostic outcomes of non-surgery strategies with hepatectomy.

Methods: The systematic searches were conducted up to April 11, 2024, across PubMed, Embase, Web of Science, and the Cochrane Library, analyzing progression-free survival (PFS) and overall survival (OS).

Background: Open surgical debridement was the main treatment option for infected pancreatic necrosis (IPN). However, it was associated with significant trauma, leading to a higher mortality rate. With the development of minimally invasive surgery, the step-up treatment principle centered around minimally invasive intervention, significantly reducing the incidence of complications and mortality rates among IPN patients.

Tumor heterogeneity, immune-suppressive microenvironment and the precise killing of tumor cells by drugs are important factors affecting tumor treatment. In this study, we developed environment-responsive drug delivery system (FM@IQ/PST&ZIF-8/DOX) based on ZIF-8 for tumor photothermal/immunotherapy/chemotherapy synergistic therapy. The prepared FM@IQ/PST&ZIF-8/DOX nanoplatfrom not only has highly drug loading capacity for chemotherapeutic drug-doxorubicin, but also erythrocyte membrance modified on their surface can endow their immunity-escaping property and prolong their blood circulation time.
