The microhardness and corrosion resistance of the TiC coatings prepared under different voltage and capacitance process parameters were studied. The research shows that the maximum microhardness of the TiC coating on sample 4 (working voltage of 20 V, working capacitance of 1000 μF) is 844.

Initial Misdiagnosis of Lung Cancer due to Elevated Carcinoembryonic Antigen in a Patient with Tuberculosis.

Background: Tuberculosis often presents on imaging in the form of a solitary nodule, sometimes accompanied by elevated CEA, which is clinically difficult to differentiate from lung cancer and prone to misdiagnosis.

Methods: Lung tissue taken by lung biopsy and sent for NGS and Xpert MTB/RIF finally led to the definitive diag-nosis of nodular foci in the upper lobe of the left lung caused by tuberculosis.

Results: Enhanced CT of the chest showed nodular foci in the upper lobe of the left lung.

Machine learning powered detection of biological toxins in association with confined lateral flow immunoassay (c-LFA).

Biological weapons, primarily dispersed as aerosols, can spread not only to the targeted area but also to adjacent regions following the movement of air driven by wind. Thus, there is a growing demand for toxin analysis because biological weapons are among the most influential and destructive. Specifically, such a technique should be hand-held, rapid, and easy to use because current methods require more time and well-trained personnel.

Capillary force-driven reverse-Tesla valve structure for microfluidic bioassays.

Biological assays involve the lysis of biological particles, enzyme reactions, and gene amplification, and require a certain amount of time for completion. Microfluidic chips are regarded as powerful devices for biological assays and diagnostics; however, they cannot achieve a high mixing efficiency, particularly in some time-consuming biological reactions. Herein, we introduce a microfluidic reverse-Tesla (reTesla) valve structure in which the fluid is affected by vortices and branch flow convergence, resulting in flow retardation and a high degree of mixing.

Organizing Pneumonia due to Secondary Invasive Pulmonary Mycosis and Cytomegalovirus Infection in a Patient with Lymphoma.

Background: Reactivation of cytomegalovirus is more common in lymphoma patients undergoing hematopoietic stem cell transplantation, but reactivation of cytomegalovirus due to chemotherapy for lymphoma has rarely been reported. We report a case of a lymphoma patient with secondary pulmonary fungal infection and cytomegalovirus infection after chemotherapy, which ultimately led to organizing pneumonia.

Methods: Percutaneous lung biopsy, Next Generation Sequencing (NGS).

Complication of Intrapulmonary Cavitary Lesions after COVID-19 Finally Proved as Pulmonary Aspergillosis.

Background: Coronavirus Disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus type 2, which is characterized by high infectiousness and diverse clinical manifestations. They are more likely to become critical in people who have underlying diseases or are immunocompromised. In the daunting task of treating patients with COVID-19, those with comorbid fungal infections are susceptible to underdiagnosis or misdiagnosis, which can ultimately lead to increased morbidity and mortality in this group of patients.

Impact of the numbers of injections of platelet rich plasma on the clinical outcomes in patients with knee osteoarthritis: A protocol for an updated network meta-analysis.

Background: Two published meta-analyses have investigated the effects of the number of injections of platelet rich plasma (PRP) on clinical outcomes in knee osteoarthritis patients, however conflicting findings were generated.

Methods: We will systematically search PubMed, Embase, and China National Knowledgement Infrastructure (CNKI) to capture additional eligible studies. After screening citations, extracting essential data, assessing the risk of bias, we will use RevMan software and Open BUGS to perform head-to-head and network meta-analysis of pain alleviation and improvement of joint functionality, respectively.

Soil respiration and its Q response to various grazing systems of a typical steppe in Inner Mongolia, China.

Background: As one of the important management practices of grassland ecosystems, grazing has fundamental effects on soil properties, vegetation, and soil microbes. Grazing can thus alter soil respiration (Rs) and the soil carbon cycle, yet its impacts and mechanisms remain unclear.

Methods: To explore the response of soil carbon flux and temperature sensitivity to different grazing systems, Rs, soil temperature (ST), and soil moisture (SM) were observed from December 2014 to September 2015 in a typical steppe of Inner Mongolia under three grazing systems: year-long grazing, rest-rotation grazing, and grazing exclusion.

Soil microbial community composition closely associates with specific enzyme activities and soil carbon chemistry in a long-term nitrogen fertilized grassland.

Due to the profound impact of nitrogen (N) input on soil systems, linking the activity and composition of soil microbial communities to soil organic carbon (SOC) is crucial to reveal the microbial-driven mechanisms underlying SOC decomposition by nitrogen fertilization. A long-term nitrogen fertilization experiment with 6 urea fertilizer gradients (0, 2, 4, 8, 16, and 32 g N m yr) was conducted on a temperate grassland. The soil basic characteristics, microbial community DNA sequences, five soil enzymes including C, N, and phosphorus cycling, and soil C fractions were measured after 14 years of N addition.
