Effects of chromium-loaded chitosan nanoparticles (Cr-CNP) on growth performance, blood metabolites, immune traits, and tissue chromium in finishing pigs were investigated. A total of 160 crossbred barrows (66.06 ± 1.01 kg initial weight) were randomly divided into four groups, each group with four pens, ten pigs per pen. Pigs were fed on the same basal diet supplemented with 0 (the control), 100, 200, and 400 μg/kg Cr from Cr-CNP. All pigs were given free access to feed and water. Eight pigs from each treatment were selected to collect blood and tissue samples after 35 days on trial for analysis of blood metabolites and immune traits and tissue chromium. The results of feeding trial showed that there were no significant difference in growth performance between control and Cr-CNP-treated groups. The supplementation of Cr-CNP decreased serum glucose (P < 0.001) in a linear and quadratic manner. Serum immunoglobulins A and M were linearly increased in Cr-CNP-treated groups (P < 0.001), and serum complement 4 in Cr-CNP-treated groups was also linearly increased (P < 0.05). Cr-CNP supplementation linearly increased the chromium content in the blood, longissimus muscle, heart, liver, kidney, and pancreas (P < 0.001). These results suggested that dietary supplementation of Cr as Cr-CNP affects serum glucose, influences immune status, and increases the tissue chromium content of blood, muscle, and selected organs in finishing pigs.

Lung cancer is an important human health concern because of its high mortality rate, with many cases caused by environmental chemicals other than tobacco. Particulate hexavalent chromium [Cr(VI)] is a well-established human lung carcinogen, but how Cr(VI) induces lung cancer is poorly understood. Chromosome instability, a hallmark of lung cancer, is considered a major driving factor in Cr(VI)-induced lung cancer.

Undifferentiated pleomorphic sarcoma (UPS) is a highly malignant mesenchymal tumor that ranks as one of the most common types of soft tissue sarcoma. Even though chemotherapy increases the 5-year survival rate in UPS, high tumor heterogeneity frequently leads to chemotherapy resistance and consequently to recurrences. In this study, we characterized the cell composition and the transcriptional profile of UPS with resistance to chemotherapy at the single cell resolution.

Excessive wear can result in irreversible damage to the cartilage. Experimental studies indicate that cartilage wear is significantly influenced by both the orientation of unidirectionally aligned surface fibers and the biphasic structure of the tissue. Given challenges with invasive in vivo wear experiments, there is a pressing need for computational models to predict wear of the cartilage accurately.

This study investigates the potential of chromium (VI) resistant bacterial isolates to alleviate heavy metal stress in fodder maize plants and enhance phytoremediation. Twenty-one bacterial strains were isolated from contaminated water, with five strains; (BHR1) (BHR2), (BHR4), (BHR5) and (BHR6) selected based on their significant plant-growth promoting (PGP) traits and heavy metal tolerance. Under chromium (Cr VI) stress, the BHR1 strain significantly improved seed germination, seedling length and vigor index of fodder maize variety (J 1007) especially at 150 mg/L Cr (VI), where these parameters increased by 3.
