Determination of paclobutrazol using square wave voltammetry based on a molecularly imprinted polymer and boron-doped copper oxide/graphene nanocomposite.

In the present study, a novel voltammetric sensor based on a boron-doped copper oxide/graphene (B-CuO-Gr) nanocomposite and molecularly imprinted polymer (MIP) was developed for the detection of paclobutrazol (PAC) in apple and orange juice samples. The B-CuO-Gr nanocomposite was prepared using sol-gel and calcination methods. After modifying glassy carbon electrodes with the B-CuO-Gr nanocomposite, PAC-imprinted electrodes were prepared in the presence of 100.

Thiram Determination in Milk Samples by Surface Plasmon Resonance Based on Molecularly Imprinted Polymers and Sulphur-Doped Titanium Dioxide.

In this work, a new surface plasmon resonance (SPR) sensor based on sulphur-doped titanium dioxide (S-TiO) nanostructures and molecularly imprinted polymer (MIP) was presented for thiram (THI) determination in milk samples. Firstly, the S-TiO nanomaterial with a high product yield was prepared by using a facile sol-gel hydrolysis technique with a high product yield. After that, UV polymerization was carried out for the preparation of the THI-imprinted SPR chip based on S-TiO using a mixture including ethylene glycol dimethacrylate (EGDMA) as the cross-linker, N,N'-azobisisobutyronitrile (AIBN) as the initiator, and methacryloylamidoglutamicacid (MAGA) as the monomer.

An underrecognized association: immune checkpoint inhibitor-related aortitis, a case report with the review of the literature.

Immune-checkpoint inhibitors (ICIs) are considered as the novel treatment modality in certain cancers. They may soon be used widely even as the first-line option for cancer treatment due to their remarkable efficacies and impacts on survival rates, particularly in cases of advanced metastatic cancer. Of note, these agents might unveil new autoimmune diseases as well as causing flare-ups of a pre-existing autoimmune disease.

A Rare False-Positive Whole-Body Scan in a Patient With Differentiated Thyroid Cancer: Unilateral Conjunctival Concretions.

131 I has been used effectively over the years in both diagnosis and therapy of differentiated thyroid cancer (DTC). Although whole-body scan with 131 I is a highly sensitive tool for detecting normal thyroid tissue and metastasis of DTC, it is not specific; therefore, false-positive images can be seen in clinical practice, and their recognition is critical for correct management. Evaluation of false-positive uptake is important because it may be confused with metastatic involvement.

68Ga-PSMA PET/CT Images of Multiple Cutaneous Metastases in a Patient With Prostate Carcinoma: Complete Response to 177Lu-PSMA-617 Treatment.

Although distant cutaneous metastasis is an uncommon presentation of prostate cancer, it remains an important diagnostic consideration as an advanced disease and a poor prognosis. Herein we present a rare case of prostate cancer patient whose multiple cutaneous metastases were treated with 177Lu-PSMA-617 radioligand treatment. To our knowledge, it is the first report in which a complete response was seen with 68Ga-PSMA PET/CT scan after 177Lu-PSMA-617 radioligand treatment.
