A 31-year-old male patient with a history of sickle cell disease (SCD) with stage V chronic kidney disease (CKD) presented for a deceased donor kidney transplant. During surgery, the transplanted kidney showed mottling and limited cortical flow, raising concerns for an intraoperative sickle cell crisis versus hyperacute rejection. Postoperative imaging revealed decreased vascularity, and the patient was treated with RBC exchange.

Upon excitation by 394 nm and 464 nm, the phosphor displays a distinct red emission peaking around 614 nm, a characteristic of f-f electronic transitions involving Eu ions.Incorporating alkali metal ions such as Li, Na and K into ZnSiO:Eu phosphor led to a remarkable increase in photoluminescence (PL) intensity.

- A new one-pot method was developed for creating chiral -protected amino acid substituted 1,2,4-oxadiazoles using hydroxyl amidine and a specific anhydride, promoting sustainability.
- This simple process does not require catalysts, making it a more efficient way to synthesize these amino acids.
- The newly synthesized compounds were tested for antibacterial activity, with one compound (4al) showing notable effectiveness against certain harmful bacteria at a minimal inhibitory concentration of 0.19 μg/mL.
Article Synopsis
- A 51-year-old man initially presented with rhabdomyolysis and progressive weakness leading to falls, without typical colorectal cancer symptoms like diarrhea.
- During his hospital stay, he developed abdominal discomfort, and further tests revealed a rectal polyp with invasive adenocarcinoma and multiple gluteal abscesses.
- This case highlights that colorectal cancer may present with atypical symptoms, such as limb weakness, and emphasizes that a lack of classic GI symptoms does not rule out the possibility of underlying GI malignancies.
Purpose: Stereotactic body radiation therapy (SBRT) has been established as a safe and effective treatment for prostate cancer. SBRT requires high accuracy to reduce treatment margins. Metal hip prostheses create artifacts that distort pelvic imaging and potentially decrease the accuracy of target/organ at risk (OAR) identification and radiation dose calculations.
