Relationship among ultrasound features, pus Mycobacterium tuberculosis load, and efficacy of antituberculosis drugs in patients with necrotizing tuberculous lymphadenitis.

For patients with necrotizing cervical tuberculous lymphadenitis (CTL) who have formed abscesses and are unwilling to undergo surgery, early and accurate assessment of drug therapy should be performed to guide subsequent clinical adjustments. This study investigated 22 patients with necrotizing CTL who underwent chemotherapy at our hospital from February 2020 to December 2022. They were diagnosed based on the positive results of pathogen detection methods (acid-fast bacillus smear, mycobacteria culture, Gene X-pert, and next-generation sequencing).

The value of nomogram model combined with contrast-enhanced ultrasound in the differential diagnosis of cervical tuberculosis lymphadenitis and metastatic lymph node.

Background: This study aimed to construct an effective Nomogram for the differential diagnosis of cervical tuberculosis lymphadenitis (CTBL) and cervical metastatic lymph node (CMLN) based on ultrasound (US).

Applying Kumpfer's resilience framework to understand the social adaptation process of the trailing parents in China.

Background: Trailing parents, a distinct group emerging from China's rapid social change and urbanization, are experiencing migration in old age, posing challenges for their social adaptation. Existing research has mainly focused on the hardships faced by this group, but few studies have focused on how they cope with change and achieve some degree of successful social adaptation. This study aimed to understand the coping and social adaptation process of trailing parents in China.

Aim: To investigate the multimodal ultrasound(MMUS) features of cervical lymphadenopathy and to assess its value in the differential diagnosis of benign and malignant cervical lymph nodes.

Methods: A retrospective analysis of 169 patients with cervical lymph node enlargement who attended Hangzhou Red Cross Hospital from March 2020 to October 2022. All patients underwent conventional ultrasound (CUS), contrast-enhanced ultrasound (CEUS), and real-time elastography (RTE), and were divided into training set and validation set.

The added value of S-detect in the diagnostic accuracy of breast masses by senior and junior radiologist groups: a systematic review and meta-analysis.

Background: S-detect is an emerging computer-aided diagnosis (CAD) technique that provides a reference for radiologists to identify breast cancer. Some studies have shown that US (ultrasound) + S-detect can improve the diagnostic accuracy of junior radiologists more than senior radiologists, but the results are inconsistent in various studies. Therefore, this meta-analysis aimed to assess the value of S-detect combined with the US outcomes from senior and junior radiologists for the diagnosis of breast cancer.

Large Photomultiplication by Charge-Self-Trapping for High-Response Quantum Dot Infrared Photodetectors.

PbS colloidal quantum dots (CQDs) are emerging as promising candidates for next-generation, low-cost, and high-performance infrared photodetectors. Recently, photomultiplication has been explored to improve the detectivity of CQD infrared photodetectors by doping charge-trapping material into a matrix. However, this relies on remote doping that could influence carrier transfer giving rise to limited photomultiplication.

Development and Poverty Dynamics in Severe Mental Illness: A Modified Capability Approach in the Chinese Context.

Albeit poverty reduction has been listed as an overarching objective in many countries' development plans, little is known about how development could shape poverty dynamics in disadvantaged groups. Guided by a modified capability framework, this study aimed to explore the long-term experiences of poverty dynamics in severe mental illness. Semi-structured interviews were carried out with 20 caregivers who provided care for persons with severe mental illness in Chengdu, China.

Silicon: quantum dot photovoltage triodes.

Silicon is widespread in modern electronics, but its electronic bandgap prevents the detection of infrared radiation at wavelengths above 1,100 nanometers, which limits its applications in multiple fields such as night vision, health monitoring and space navigation systems. It is therefore of interest to integrate silicon with infrared-sensitive materials to broaden its detection wavelength. Here we demonstrate a photovoltage triode that can use silicon as the emitter but is also sensitive to infrared spectra owing to the heterointegrated quantum dot light absorber.

Poverty transitions in severe mental illness: longitudinal analysis of social drift in China, 1994-2015.

Duration of untreated psychosis (DUP) and outcome of people with schizophrenia in rural China: 14-year follow-up study.

This study aims to examine the relationship between the duration of untreated psychosis (DUP) and 14-year outcomes of schizophrenia in a Chinese rural area. Participants with schizophrenia (n = 510) were identified in an epidemiological investigation of 123 572 people aged 15 years and older in 1994 and followed up in 2008 in Xinjin, Chengdu, China. Longer DUP (>6 months) was common in participants (27.

Decreasing graphene synthesis temperature by catalytic metal engineering and thermal processing.

Chemical vapor deposition (CVD) from gaseous hydrocarbon sources has shown great promise for large-scale graphene growth, but the high growth temperature, typically 1050 °C, requires precise and expensive equipment and makes the direct deposition of graphene in electronic device manufacturing processes unfeasible due to the severe physical damage to substrates. Here we demonstrate a facile route to synthesize graphene by catalytic metal engineering and thermal processing. The engineered catalytic metal (copper) with carbon implantation could lower the synthetic temperature to 700 °C.

Controlled direct growth of Al2O3-doped HfO2 films on graphene by H2O-based atomic layer deposition.

Graphene has been drawing worldwide attention since its discovery in 2004. In order to realize graphene-based devices, thin, uniform-coverage and pinhole-free dielectric films with high permittivity on top of graphene are required. Here we report the direct growth of Al2O3-doped HfO2 films onto graphene by H2O-based atom layer deposition (ALD).

Improvement of Al2O3 films on graphene grown by atomic layer deposition with pre-H2O treatment.

We improve the surface of graphene by atomic layer deposition (ALD) without the assistance of a transition layer or surface functionalization. By controlling gas-solid physical adsorption between water molecules and graphene through the optimization of pre-H2O treatment and two-step temperature growth, we directly grew uniform and compact Al2O3 films onto graphene by ALD. Al2O3 films, deposited with 4-cycle pre-H2O treatment and 100-200 °C two-step growing process, presented a relative permittivity of 7.
