Ultra-high frequency ultrasound (UHFUS) applications in Sjogren syndrome: narrative review and current concepts. [PDF]

Gland Surg, 2020
Primary Sjogren's syndrome (SS) is a systemic autoimmune chronic inflammatory disease with predominant involvement of the exocrine glands, particularly the salivary glands (SGs). The role of salivary glands ultrasound (SGUS) in the work-up of patients with primary Sjogren syndrome (SS) is progressively increasing due to its useful support in diagnosis ...

Separation of Overlapping Linear Frequency Modulated (LFM) Signals Using the Fractional Fourier Transform [PDF]

, 2010
Linear frequency modulated (LFM) excitation combined with pulse compression provides an increase in SNR at the receiver. LFM signals are of longer duration than pulsed signals of the same bandwidth; consequently, in many practical situations, maintaining

Development of human monoclonal antibodies against TARM1 by yeast display

FEBS Open Bio, EarlyView.
Human monoclonal antibodies against TARM1 are generated by yeast display‐guided selection. These antibodies bind to soluble and cell‐surface forms of TARM1. Also, these antibodies exhibit agonistic activity in the NFAT‐GFP reporter assay, indicating that TARM1 signaling can be functionally modulated by antibodies and suggesting TARM1 as a potential ...

Intraoperative evaluation of cervical nerve root avulsion using ultra-high-frequency ultrasound system. [PDF]

Case Reports Plast Surg Hand Surg, 2019
Avulsion of C5 and C7 nerve roots was confirmed intraoperatively in a 21 year old male presenting after motor vehicle accident with confirmed absence of somatosensory evoked potentials upon stimulation via ultra-high-frequency ultrasound (70 MHz). Ultra-high-frequency ultrasound can be used as a reliable tool to directly visualise nerve injury.
