Computed tomography in the follow-up of patients nephrectomized for adenocarcinoma

A retrospective study was carried out of 159 CT examinations acquired in 64 patients who underwent unilateral nephrectomy for renal-cell carcinoma (34 in the left-hand side and 30 in the right-hand side). Thirty-nine patients were examined twice in the three years following nephrectomy; 25 were examined three or more times over a 5-year period after nephrectomy. Acute or chronic inflammatory disease was demonstrated in 6 patients (4 abscesses were detected by means of clinico-radiologic signs and 2 by means of cytology after CT-guided needle biopsy). Twenty patients had local recurrences 2-7 cm phi: in 17 of them the diagnosis was confirmed by CT-guided percutaneous FNAB; 15 patients had liver metastases, in 3 of them associated with local recurrences; 26 patients were free of both local recurrences and distant metastases. The authors analyze the value of CT in the definition of post-nephrectomy anatomic alterations, in the early detection and staging of local recurrences, and in the differentiation between postoperative fibrosis and complications. Moreover, the value is stressed of CT-guided FNAB of suspicious lesions. Our study suggests the value of a methodical CT follow-up of asymptomatic post-nephrectomy patients.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
