In a constrained PRF, the owner of the PRF key K can generate constrained keys Kf that allow anyone to evaluate the PRF on inputs x that satisfy the predicate f (namely, where f(x) is “true”) but reveal no information about the PRF evaluation on the other inputs. A private constrained PRF goes further by requiring that the constrained key Kf hides the predicate f . Boneh, Kim and Montgomery (EU...

BACKGROUND Pulsed radiofrequency (PRF) therapy is a clinical treatment utilizing electromagnetic energy aimed to relieve neuropathic pain. This is the first study examining the modulated expression of pain regulatory genes following the induction of the spared nerve injury (SNI) pain model and subsequently treated with PRF therapy. OBJECTIVES The present study investigated the behavioral effi...

This study aims to determine if high-voltage PRF could effectively adjunct epidural adhesiolysis (EA) in treating patients with chronic lumbosacral radiating pain (LSRP) and neuropathic characteristics. A total of 409 suffering from a single leg-radiating lasting for > six months unresponsive previous treatments were divided into three different groups: Group 1 consisted 227 LSRP lumbar sten...

Avulsed teeth that are replanted dried are more prone to loss. Recent tissue engineering studies focus onfabrication of various cell delivery systems to improve the overall prognosis of such teeth. To evaluate this newcell transplant method, we initially aimed at designing of PRF scaffold and determining BMMSCs viabilityand function on the fabricated scaffold. To test this concept in-vitro, hum...

Background: Changes in tendon structure after its rupture may also affect the likelihood of re-injury or strain injury to the musculotendinous complex of the plantar flexor. Purpose: The aim of our study is to investigate ankle biomechanical properties and clinical features of acute rupture of the Achilles tendon treated with open suture and PRF augmentation. Study design: Cohort study (NRS). M...

Pseudo-relevance feedback (PRF) is an effective technique for improving the retrieval performance through updating the query model using the top retrieved documents. Previous work shows that estimating the effectiveness of feedback documents can substantially affect the PRF performance. Following the recent studies on theoretical analysis of PRF models, in this paper, we introduce a new constra...

There is extensive controversy over whether the adult visual cortex is able to reorganize following visual field loss (scotoma) as a result of retinal or cortical lesions. Functional magnetic resonance imaging (fMRI) methods provide a useful tool to study the aggregate receptive field properties and assess the capacity of the human visual cortex to reorganize following injury. However, these me...

We define a new black-box property for cryptographic hash function families H : {0, 1}×{0, 1}∗ → {0, 1} which guarantees that for a randomly chosen hash function HK from the family, everything “non-trivial” we are able to compute having access to the key K, we can compute only with oracle access to HK . If a hash function family is pseudo-random and has the black-box property then a randomly ch...

Neuropathic pain following brachial plexus injury is a severe sequela that is difficult to treat. Pulsed radiofrequency (PRF) has been proved to reduce neuropathic pain after nerve injury, even though the underlying mechanism remains unclear. This case report describes the use of ultrasound-guided PRF to reduce neuropathic pain in a double-level upper extremity nerve injury. A 25-year-old man w...

AIM To analyse the effect of leucocyte- and platelet-rich fibrin (L-PRF) on bone regeneration procedures and osseointegration. MATERIALS AND METHODS An electronic and hand search was conducted in three databases (MEDLINE, EMBASE and Cochrane). Only randomized clinical trials, written in English where L-PRF was applied in bone regeneration and implant procedures, were selected. No follow-up re...
