Radiologists play an essential role in assessing hepatocellular carcinoma treatment response and help guide further clinical management of patients. Interpretation of treatment response after locoregional therapy is challenging. The post-treatment imaging findings vary and depend on the type of treatment, the degree of treatment response, time interval after treatment and several other factors. Given the widespread use of local-regional therapies, understanding the appearance of treated lesions has become crucial to allow for a more accurate interpretation of post-treatment imaging. Several response criteria including the recently introduced Liver Imaging Reporting and Data System (LI-RADS) treatment response algorithm (TRA) are currently used to assess treatment response. This review article describes the imaging assessment of HCC treatment response after several locoregional therapies using various response assessment criteria, emphasizing the LI-RADS treatment algorithm.

Purpose Of Review: Optimal duration of therapy in SSTIs - a heterogeneous group of infections - remains unknown. The advances in knowledge of antibiotic duration of treatment in selected SSTIs that can impact clinical practice and published in the last 18 months are reviewed.
Recent Findings: Recent evidence indicates that few patients receive guideline concordant empiric antibiotics and appropriate duration in the United States, although this likely can be extrapolated to other countries.

The P2YR is activated by UDP and UDP glucose and is involved in many human inflammatory diseases. Based on the molecular docking analysis of currently reported P2YR antagonists and the crystallographic overlap study between PPTN and compound , a series of 3-substituted 5-amidobenzoate derivatives were designed, synthesized, and identified as promising P2YR antagonists. The optimal compound (methyl 3-(1-benzo[]imidazol-2-yl)-5-(2-(-tolyl) acetamido)benzoate, IC = 0.

Herpes simplex virus (HSV) infection is one of the most prevalent viral infections worldwide. In general, host immunity is sufficient to clear viral shedding and recurrences, although it is insufficient to prevent subsequent virologic reactivations. In immunocompromised patients, prolonged and difficult-to-treat HSV infections may develop.
