Article Abstract
We report a rare domestic case of exposure to tianeptine and use of a novel, extended-release, six-armed, star-shaped, drug delivery capsule. A 40-year-old male with a history of depression, anxiety, ethanol, opioid, cannabis, and tobacco use disorders presented to the emergency department (ED) from a substance abuse residential recovery treatment program after developing hypertension, tachycardia, and tremor for two day. He used an extended-release, six-armed, star-shaped, drug delivery device he purchased online, filling each arm with 15 mg of tianeptine (90 mg total). His intention was to mitigate the symptoms of kratom/opioid withdrawal through this extended-release method while simultaneously undergoing formal treatment for ethanol withdrawal. Tianeptine is an atypical tricyclic antidepressant that exerts complex mechanisms of action including serotonin (5-HT) neuromodulation as well as full μ-opioid and ∂-opioid receptor agonism. The capsule itself is made of caprolactone, which is a bioabsorbable material similar to absorbable sutures, initially developed as a long-term enteral antimalarial delivery method and is not FDA approved for human use. Over the course of the patients two day hospitalization course he developed symptoms consistent with uncomplicated ethanol withdrawal, which were treated with as-needed phenobarbital. No clinical manifestations of opioid or serotonin toxicity developed. Serial EKGs and telemetry monitoring remained unchanged. The patient was then medically cleared and discharged back to the residential recovery treatment program.

Background: Alectinib is a second generation of anaplastic lymphoma kinase (ALK) inhibitor that has been approved for the treatment of advanced non-small-cell lung cancer (NSCLC) with ALK rearrangements. Hepatotoxicity is the most common adverse drug reaction. However, there is currently no published report on the pathologic findings of alectinib-induced hyperbilirubinemia.

Infection induced by multidrug-resistant bacteria is now the second most common cause of accidental death worldwide. However, identifying a high-performance strategy with good efficiency and low toxicity is still urgently needed. Antibacterial photodynamic therapy (PDT) is considered a non-invasive and efficient approach with minimal drug resistance.

The heightened susceptibility to skin cancer correlates with exposure to ultraviolet (UV) radiation, which can induce various cutaneous injuries. Inorganic UV filters, like zinc oxide (ZnO), are extensively utilized in sunscreens owing to their capacity to scatter and reflect UV radiation. The efficacy of inorganic UV filters can be augmented across a wider spectrum through synergistic combinations with other active compounds, such as organic UV filters.

This paper presents an innovative approach that utilizes self-synthesized homopolymers of polyvinylpyrrolidone (PVP) with different architectures as effective matrices for inhibiting the crystallization of naproxen (NAP). We have thoroughly investigated amorphous solid dispersions containing NAP and (i) self-synthesized linear PVP, (ii) self-synthesized three-armed star-shaped PVP, and (iii) self-synthesized linear PVP with a mass (M) corresponding to the length of one arm of the star polymer, as well as (iv) commercial linear PVP K30 as a reference. Differential scanning calorimetry (DSC), X-ray diffraction (XRD), and infrared spectroscopy (FTIR) studies, as well as molecular dynamics simulations were conducted to gain comprehensive insights into the thermal and structural properties, as well as intermolecular interactions in the NAP-PVP systems.

Nanoparticle interactions with biological systems are intricate processes influenced by various factors, among which the formation of protein corona plays a pivotal role. This research investigates a novel aspect of nanoprotein corona-cell interactions, focusing on the impact of the protein corona on the recovery of disrupted tight junctions in endothelial cells. We demonstrate that the protein corona formed on the surface of star-shaped nanoparticles induces the aggregates of ZO-1, which is quite important for the barriers' integrity.
