It is well understood that the biopharmaceutical industry must improve efficiency along the path from laboratory concept to commercial product. In vivo imaging is recognized as a useful method to provide biomarkers for target engagement, treatment response, safety, and mechanism of action. Imaging biomarkers have the potential to inform the selection of drugs that are more likely to be safe and effective. Most of the imaging modalities for biopharmaceutical research are translatable to the clinic. In vivo imaging does not require removal of tissue to provide biomarkers, thus reducing the number of valuable preclinical subjects required for a study. Longitudinal imaging allows for quantitative intra-subject comparisons, enhancing statistical power, and further reducing the number of subjects needed for the evaluation of treatment effects in animal models. The noninvasive nature of in vivo imaging also provides a valuable approach to alleviate or minimize potential pain, suffering or distress.

Enhancing the retention of recent memory traces through sleep reactivation is possible via Targeted Memory Reactivation (TMR), involving cueing learned material during post-training sleep. Evidence indicates detectable short-term microstructural changes in the brain within an hour after motor sequence learning, and post-training sleep is believed to contribute to the consolidation of these motor memories, potentially leading to enduring microstructural changes. In this study, we explored how TMR during post-training sleep affects performance gains and delayed microstructural remodeling, using both standard Diffusion Tensor Imaging (DTI) and advanced Neurite Orientation Dispersion & Density Imaging (NODDI).

A 36-year-old woman diagnosed with complicated cholecystolithiasis underwent elective laparoscopic cholecystectomy (LC), then converted to open cholecystectomy because of a massive intraoperative bleeding. Hemostasis was performed with clipping and suturing the source of bleeding. In post-operative period, the patient suffered from persistent anemia associated with hemoperitoneum diagnosed through abdominal CT scanning, in absence of any sign of active bleeding.

The resistance of cancer cells to apoptosis poses a significant challenge in cancer therapy, driving the exploration of alternative cell death pathways such as pyroptosis, known for its rapid and potent effects. While initial efforts focused on chemotherapy-induced pyroptosis, concerns about systemic inflammation highlight the need for precise activation strategies. Photothermal therapy emerges as a promising non-invasive technique, minimizing pyroptosis-related side effects by targeting tumors spatially and temporally.

Acute myocardial infarction (MI) remains a leading cause of mortality worldwide, with inflammatory and reparative phases playing critical roles in disease progression. Currently, there is a pressing need for imaging techniques to monitor immune cell infiltration and inflammation activity during these phases. We developed a novel probe, Tc-HYNIC-mAb, utilizing a monoclonal antibody that targets the voltage-gated potassium channel 1.

The long-term health of former athletes with a history of multiple concussions and/or repetitive head impact (RHI) exposure has been of growing interest among the public. The true proportion of dementia cases attributable to neurotrauma and the neurobehavioral profile/sequelae of multiple concussion and RHI exposure among athletes has been difficult to determine. Across three exposure paradigms (i.
