Discovery of an Orally Efficacious Pyrazolo[3,4-]pyrimidine Benzoxaborole as a Potent Inhibitor of .

Cryptosporidiosis is a diarrheal disease caused by the parasite resulting in over 100,000 deaths annually. Here, we present a structure-activity relationship study of the benzoic acid position (R) of pyrazolo[3,4-]pyrimidine lead SLU-2815 (), an inhibitor of parasite phosphodiesterase PDE1, resulting in the discovery of benzoxaborole SLU-10906 () as a benzoic acid bioisostere. Benzoxaborole is 10-fold more potent than against the parasite in a cell-based infection model (EC = 0.

Differential editing efficiencies in cereal crops: a comparative analysis of tRNA and ribozyme multiplexed guide delivery.

Cereal transformation and gene editing can be a complex and costly undertaking. It is therefore important to validate and understand the performance of the components to achieve high rates of transformation and gene editing. Here, we have made a direct comparison of different CRISPR/Cas9 guide systems to target the genome in three cereal species.

Bedside Small Bowel Follow-Through: The Role in the Management of Adhesive Small Bowel Obstruction.

Background:  Adhesive small bowel obstruction (ASBO) accounts for the majority of hospitalizations related to SBO following abdominal surgery. Delays in the management of ASBO are associated with longer hospital stays and increased mortality rates, making it imperative to establish an efficient way of determining which patients need surgical intervention.

Purpose: To evaluate the contribution of bedside small bowel follow-through (BSBFT) in the management of suspected ASBO.

Into the Future: Fighting Melanoma with Immunity.

Immunotherapy offers a novel and promising option in the treatment of late-stage melanoma. By utilizing the immune system to assist in tumor destruction, patients have additional options after tumor progression. Immune checkpoint inhibitors reduce the ability for tumors to evade the immune system by inhibiting key surface proteins used to inactivate T-cells.

Safety evaluation of targeted osmotic lysis therapy in Beagles.

Objective: The objective of this study was to satisfy the US FDA's Center for Devices and Radiological Health regarding the safety of targeted osmotic lysis (TOL), a novel treatment for advanced carcinomas, in Beagle dogs.

Methods: 12 intact Beagle dogs, 6 males and 6 females, were divided into 2 treatment groups of 6, each receiving 3 TOL cycles. For each 6-day cycle, digoxin was administered orally at 0.
