Piperazine-based compounds have garnered significant attention due to their notable biological and pharmacological activities, making them essential in fine chemical and pharmaceutical applications. In this study, we managed to synthesize a novel hybrid bis-cyanoacrylamide bearing the piperazine core via phenoxymethyl linker and incorporating sulphamethoxazole moiety. The novel compound was fully characterized using different spectral data including 1H-NMR, C-NMR, and FTIR spectroscopy.

Background: Childhood sleep problems are common and impact physical and emotional health. Prior work suggests that prenatal maternal depression and anxiety associate with disturbed child sleep in infancy. The current study evaluated whether these same associations extend to children at 3 years of age, and if so, whether the timing of symptoms in pregnancy is relevant.

A 68-year-old patient came to the emergency department complaining of headaches and general weakness for the past month. The patient is known to have myeloproliferative disease. Non-contrast computer tomography showed a hyperdense extra-axial collection in bilateral frontoparietal regions, which was presumed to be bilateral subdural hematoma as the initial diagnosis.

This article discusses the rarity of primary cardiac tumors, particularly angiosarcomas, accounting for 10% of primary cardiac neoplasms. The article highlights the challenge of early diagnosis due to nonspecific symptoms. The importance of sectional imaging, particularly computed tomography (CT) scans, in emergent situations is emphasized.

Stent migration is a rare but significant complication following endovascular procedures. Techniques for managing dislodged stents have included surgical, endovascular, and conservative approaches. This case details a patient who had a covered stent placed within the left renal vein which later migrated to the pulmonary artery causing damage to the tricuspid valve.

Chronic myelomonocytic leukemia (CMML) presents as a complex hematologic malignancy with myelodysplastic and myeloproliferative features. Our case report explores the rare coexistence of CMML with immune thrombocytopenic purpura (ITP) in a 63-year-old female patient. CMML diagnosis followed World Health Organization criteria, and the patient was classified as having high-risk myelodysplastic syndrome (MDS)-CMML stage 2.

Article Synopsis
  • Intracranial germ cell tumors (GCTs) are rare, harmful tumors that usually show up around puberty, especially in the pineal region of the brain.
  • A 20-year-old boy had a pineal germinoma, which caused him to vomit and feel less conscious; doctors used MRI scans to find the tumor and placed a special device to relieve pressure in his brain.
  • There isn't a clear way to treat these tumors yet, so more studies are needed to find the best treatment methods.

Article Synopsis
  • This study focuses on modifying mesenchymal stromal cells (MSCs) to create a new type of antigen-presenting cells (A1-reprogrammed MSCs or ARM), which are better at activating CD8 T cells for immune responses.
  • Researchers discovered that the molecule A1 enhanced MSCs' abilities to uptake and process antigens, improving their overall effectiveness.
  • In mouse models, the ARM-based vaccines demonstrated significant therapeutic effects against lymphoma and melanoma, particularly when used with anti-PD-1 immune checkpoint inhibitors, indicating potential for a new adaptable cancer vaccine approach.

Worldwide prevalence of cervical cancer decreased significantly with the use of human papilloma virus (HPV)-targeted prophylactic vaccines. However, these multivalent antiviral vaccines are inert against established tumors, which leave patients with surgical ablative options possibly resulting in long-term reproductive complications and morbidity. In an attempt to bypass this unmet medical need, we designed a new E7 protein-based vaccine formulation using Accum™, a technology platform designed to promote endosome-to-cytosol escape as a means to enhance protein accumulation in target cells.

December 2023

Hepatic artery complications can be divided into 2 different categories, nonocclusive and steno-occlusive disease. Steno-occlusive disease is a collective term that encompasses hepatic artery thrombosis, hepatic artery stenosis, and hepatic arterial kinks, while nonocclusive arterial disease encompasses less than 5% of complications and is a collective term used to describe arteriovenous fistulae, pseudoaneurysms, arterial rupture and nonocclusive hepatic artery hypoperfusion syndrome. This article details the angiographic techniques and definitions needed to accurately diagnose arterial transplant complications and describes the technical aspects and results of endoluminal management of these arterial complications.

Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disorder characterized by the destruction of insulin-secreting beta cells in the pancreas, resulting in metabolic disturbances and long-term complications. While subcutaneous insulin remains the primary approach for achieving normoglycemia, pancreatic transplantation has emerged as an effective intervention for long-standing T1DM, providing insulin independence and normalized glycosylated hemoglobin levels. However, complications associated with pancreatic transplantation are frequent, necessitating thorough evaluation using diverse imaging modalities.

This paper presents a dataset of bird's eye chilies in a single farm for semantic segmentation. The dataset is generated using two cameras that are aligned left and right forming a stereo-vision video capture. By analyzing the disparity between corresponding points in the left and right images, algorithms can calculate the relative distance of objects in the scene.

Vascular access is a crucial step, which every interventional cardiologist needs to be skilled with to consistently achieve excellent periprocedural outcomes. Some operators argue that it is the most important aspect of the entire intervention. Hence, careful planning of vascular access in an individualized fashion - based on the patient's clinical status, anatomy, and technical requirements of the intervention - is the first step in securing optimal procedural safety and successful results.

Prediction of indoor airflow distribution often relies on high-fidelity, computationally intensive computational fluid dynamics (CFD) simulations. Artificial intelligence (AI) models trained by CFD data can be used for fast and accurate prediction of indoor airflow, but current methods have limitations, such as only predicting limited outputs rather than the entire flow field. Furthermore, conventional AI models are not always designed to predict different outputs based on a continuous input range, and instead make predictions for one or a few discrete inputs.
