Assessment of 6MV flattening filter free (FFF) beam commissioning parameters for Versa HD and TrueBeam: A comparison study

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Flattening filter‐free (FFF) beams are increasingly deployed for stereotactic body radiotherapy (SBRT) and stereotactic radiosurgery (SRS). The Elekta Versa HD (VHD) and Varian TrueBeam (TB) are the two most widely used FFF‐capable platforms; however, no prior study has compared their 6 MV FFF commissioning parameters under fully ...

Quantitative evaluation of respiratory motion‐induced blurring in expiratory‐phase CBCT for pancreatic SBRT

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is widely used in image‐guided radiotherapy because it reflects the patient's anatomy immediately before treatment. However, CBCT images of the abdominal organs, including the pancreas, are often degraded by respiratory motion.

Affinity‐Tuned Albumin Hitchhiking Extends the Bioorthogonal Capture Window in Pretargeting Radiotheranostics

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 29, 7 August 2026.
Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.

Repetitive Transcranial Magnetic Stimulation of the mPFC Ameliorates Stress‐Induced Hyperalgesia by Alleviating Microglia Activation in Rats

open access: yesBrain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Purpose Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive neuromodulation technique that uses magnetic fields to stimulate or inhibit specific populations of neurons in the brain. rTMS targeting the cortex has emerged as an effective treatment for chronic pain.

Intermittent Hypoxia Exacerbates Lipopolysaccharide‐Induced Neurobehavioral Abnormalities: The Role of Neuroinflammation and Synaptic‐Related Proteins

open access: yesBrain and Behavior, Volume 16, Issue 8, August 2026.
ABSTRACT Background Sepsis is a common systemic inflammatory disease clinically observed in patients with severe trauma or infectious diseases. Lipopolysaccharide (LPS) serves as a classic tool for studying infection‐related neuroinflammation and behavioral changes.
