Renal claudin-14 expression is not required for regulating magnesium balance in mice.

Am J Physiol Renal Physiol 2021 Apr 5. Epub 2021 Apr 5.

Department of Cardiovascular and Renal Research, Institute of Molecular Medicine, University of Southern Denmark, Denmark.

The kidneys play a crucial role in maintaining calcium (Ca) and magnesium (Mg) homeostasis by regulating these minerals' reabsorption. In the thick ascending limb of Henle's loop (TAL), Ca and Mg are reabsorbed through the tight junctions by a shared paracellular pathway formed by claudin-16 and claudin-19. Hypercalcemia activates the Ca-sensing receptor (CaSR) in the TAL, causing upregulation of the pore-blocking claudin-14 (CLDN14) that reduces Ca and Mg reabsorption from this segment. Read More

Performance analysis of lightweight CNN models to segment infectious lung tissues of COVID-19 cases from tomographic images.

PeerJ Comput Sci 2021 22;7:e368. Epub 2021 Feb 22.

School of Electrical Engineering, Vellore Institute of Technology, Vellore, Tamil Nadu, India.

The pandemic of Coronavirus Disease-19 (COVID-19) has spread around the world, causing an existential health crisis. Automated detection of COVID-19 infections in the lungs from Computed Tomography (CT) images offers huge potential in tackling the problem of slow detection and augments the conventional diagnostic procedures. However, segmenting COVID-19 from CT Scans is problematic, due to high variations in the types of infections and low contrast between healthy and infected tissues. Read More

Rev Cardiovasc Med 2021 03;22(1):83-95

Department of Medicine, Cleveland Clinic Foundation, Cleveland, OH 44111, USA.

The coronavirus disease-19 (COVID-19) pandemic has forced hospitals to prioritize COVID-19 patients, restrict resources, and cancel all non-urgent elective cardiac procedures. Clinical visits have only been facilitated for emergency purposes. Fewer patients have been admitted to the hospital for both ST-segment elevation myocardial infarctions (STEMI) and non-ST segment elevation myocardial infarctions (NSTEMI) and a profound decrease in heart failure services has been reported.

The iodide transport defect-causing Y348D mutation in the Na/I symporter (NIS) renders the protein intrinsically inactive and impairs its targeting to the plasma membrane.

Thyroid 2021 Mar 27. Epub 2021 Mar 27.

Vanderbilt University, 5718, Molecular Physiology and Biophysics, Nashville, Tennessee, United States;

Background: The sodium/iodide symporter (NIS) mediates active transport of iodide (I) into the thyroid gland. Mutations in the SLC5A5 gene, which encodes NIS, cause I transport defects (ITDs)-which, if left untreated, lead to congenital hypothyroidism and consequent cognitive and developmental deficiencies. The ITD-causing NIS mutation Y348D, located in transmembrane segment (TMS) 9, was reported in three Sudanese patients. Read More

Short-segment Internal Trapping for Symptomatic Thrombosed Large Fusiform Vertebral Artery Aneurysms (Bird's Nest Trapping): A Technical Note.

Neurol Med Chir (Tokyo) 2021 Feb 26. Epub 2021 Feb 26.

Department of Neurosurgery, Nagoya University Graduate School of Medicine.

Internal trapping with coils is an established treatment of symptomatic large non-branching thrombosed fusiform vertebral artery aneurysms (VAA). However, when perforators arise near the aneurysm neck, parent artery occlusion has a high risk of causing medullary infarction. As an alternative treatment, we performed short-segment internal trapping of the artery using n-butyl-2-cyanoacrylate (NBCA) and coils (bird's nest trapping). Read More

Treatment of sacroiliac joint laxity-induced coronal imbalance with the kickstand rod technique.

Br J Neurosurg 2021 Feb 20:1-6. Epub 2021 Feb 20.

Department of Neurosurgery, Washington University School of Medicine, St. Louis, MO, USA.

Background: Considerations of the sacroiliac joint (SIJ) and its role in causing lower back and limb pain have taken a secondary role ever since Mixter and Barr's hallmark article in 1934 on the herniated nucleus pulposus. However, recent literature has highlighted the contribution of sacroiliac joint degeneration in the development of failed back surgery syndrome (FBSS), especially in patients undergoing lumbar or lumbosacral spinal fusion surgeries. Many reports have studied the anatomy, physiology, and clinical significance of the sacroiliac joint, but none have linked its dysfunction with other spinal deformities. Read More
