Multiple Myeloma Rather Than Metastatic Lung Cancer: An Unexpected Cause of Spinal Cord Compression.

Spinal cord compression caused by cancer metastasis is a medical emergency that should be managed positively. Both multiple myeloma and lung cancer can lead to metastatic deposits in the spinal column to induce compression of the spinal cord. However, co-occurring multiple myeloma and lung cancer in a single patient causing spinal cord compression are rarely reported in the literature.

Multiplex immunofluorescence staining and image analysis assay for diffuse large B cell lymphoma.

With the explosion of immuno-oncology and the approval of many immune checkpoint therapies by regulatory agencies in the last few years, understanding the tumor microenvironment (TME) in the context of patients' immune status has become essential. Among available immune profiling techniques, multiplex immunofluorescence (mIF) assays offer the unique advantage of preserving the architectural features of the tumor and revealing the spatial relationships between tumor cells and immune cells. A number of mIF and image analysis assays have been described for solid tumors but most are not sufficiently suitable in lymphoma, where the lack of clear tumor-stromal boundaries and high tumor density present significant challenges.

Validation of the Simplified Chinese-character Version of the International Physical Activity Questionnaire-Long Form in Urban Community-dwelling Adults: a Cross-sectional Study in Hangzhou, China.

Objective: To assess the test-retest reliability and criterion validity of the Simplified Chinese-character version of the International Physical Activity Questionnaire Long form (IPAQ-L) in urban community-dwelling adults in Hanghzou, China.

Methods: A total of 158 eligible participants aged 25-59 years from 6 neighbourhoods in two central districts of Hangzhou completed the IPAQ-L questionnaire twice within a 7-day interval. Half of the subjects wore pedometers during the first 7 days.

Structure of the human Cereblon-DDB1-lenalidomide complex reveals basis for responsiveness to thalidomide analogs.

The Cul4-Rbx1-DDB1-Cereblon E3 ubiquitin ligase complex is the target of thalidomide, lenalidomide and pomalidomide, therapeutically important drugs for multiple myeloma and other B-cell malignancies. These drugs directly bind Cereblon (CRBN) and promote the recruitment of substrates Ikaros (IKZF1) and Aiolos (IKZF3) to the E3 complex, thus leading to substrate ubiquitination and degradation. Here we present the crystal structure of human CRBN bound to DDB1 and the drug lenalidomide.

Effects of spray application of lanthanum and cerium on yield and quality of Chinese cabbage (Brassica chinensis L) based on different seasons.

The use of single light rare earth elements in agriculture was studied using the application of single rare earth elements (La and Ce) to Chinese cabbage (Brassica chinensis L.) in field plot experiments where the soil conditions remained the same but the season (spring or autumn) in which application occurred was altered. The results showed that the Chinese cabbage's nutrition quality between the two seasons had obvious differences.
