Morel-Lavallée lesion around the knee successfully treated with video-assisted endoscopic débridement: A case report.

We report a chronic Morel-Lavallée lesion around the knee in a competitive high schooler softball player, successfully treated with video-assisted endoscopic debridement. Endoscopic surgery is a viable option to treat Morel-Lavallée lesions in active patients who seek a rapid return to sport. The potential advantages of an endoscopic treatment would be a faster healing process and an earlier return to motion and function due to a less morbid and more cosmetic surgical approach.

Signaling via a CD28/CD40 chimeric costimulatory antigen receptor (CoStAR™), targeting folate receptor alpha, enhances T cell activity and augments tumor reactivity of tumor infiltrating lymphocytes.

Transfer of autologous tumor infiltrating lymphocytes (TIL) to patients with refractory melanoma has shown clinical efficacy in a number of trials. However, extending the clinical benefit to patients with other cancers poses a challenge. Inefficient costimulation in the tumor microenvironment can lead to T cell anergy and exhaustion resulting in poor anti-tumor activity.

High-affinity CD8 variants enhance the sensitivity of pMHCI antigen recognition via low-affinity TCRs.

CD8 T cell-mediated recognition of peptide-major histocompatibility complex class I (pMHCI) molecules involves cooperative binding of the T cell receptor (TCR), which confers antigen specificity, and the CD8 coreceptor, which stabilizes the TCR/pMHCI complex. Earlier work has shown that the sensitivity of antigen recognition can be regulated in vitro by altering the strength of the pMHCI/CD8 interaction. Here, we characterized two CD8 variants with moderately enhanced affinities for pMHCI, aiming to boost antigen sensitivity without inducing non-specific activation.

Protein fractionation of Hibiscus cannabinus (kenaf) seeds, its characterization, and potential use for water treatment.

This study evaluates the coagulation performance of kenaf protein fractions (KPFs) comprising of albumin (AlbKP), globulin (GloKP), prolamin (ProKP), and glutenin (GluKP), in the treatment of high (500 NTU), medium (150 NTU), and low (30 NTU) turbidity water. Based on preliminary experimental results, the study focused on GloKP due to it outperforming the other kenaf coagulation products (KCPs) in all water types tested. The influence of GloKP, both as a primary coagulant and coagulant aid to aluminum sulfate (AS) on organic matter removal, was examined.
