objectives: to compare the outcomes of prone and supine lumbar traction in patients with chronic discogenic low back pain. methods: the test was prospective and randomized control trial. the structure of trial was urban physical medicine and rehabilitation clinic. participants was included of a total of 124 subjects with chronic low back pain (lbp) and evidence of a degenerative and/or herniate...

The aim was to compare ovarian response and clinical outcome of potential high-responders after stimulation with highly purified menotropin (HP-hMG) or recombinant follicle-stimulating hormone (rFSH) for in vitro fertilisation/intracytoplasmic sperm injection. Retrospective analysis was performed on data collected in two randomized controlled trials, one conducted following a long GnRH agonist ...

This paper reopens the long dormant topic of natural language updates to databases. A protocol to handle database updates of the IDM (Insert-Delete-Modify) class is proposed and implemented. This protocol exploits modern relational update facilities and constraints and structures update dialogues using DAMSL dialogue acts. The protocol may be used with any natural language parser that maps to r...

We describe an efficient protocol for verifiable quantum oblivious transfer. The protocol, which can be implemented with present technology, is secure against cheaters with unlimited computing power and with the ability to store the particles for an arbitrarily long period of time. The protocol is based on the following two entangled states: |Φ〉 = 1 √ 2 (|↑↑〉+ |↓ x〉) and |Ψ〉 = 1 √ 2 (|↑↑〉+ |↓ −...

Security protocols are small programs that are executed in hostile environments. Many results and tools have been developed to formally analyze the security of a protocol. However even when a protocol has been proved secure, there is absolutely no guarantee if the protocol is executed in an environment where other protocols, possibly sharing some common identities and keys like public keys or l...

In a prospective randomized study, we examined whether a novel method of ovarian stimulation, the bromocriptine-rebound method, improves in vitro fertilization (IVF) outcomes compared with the conventional long protocol using GnRH agonist and human menopausal gonadotropin (hMG). Ovulatory women with previous failed IVF-embryo transfer using the long protocol were prospectively assigned to eithe...

BACKGROUND Oocyte retrieval failure following an ovarian hyperstimulation protocol is uncommon in assisted reproductive technology (ART) programs. We analyzed the predictive factors for oocyte retrieval failure following controlled ovarian hyperstimulation (COH) with gonadotropin-releasing hormone (GnRH) agonist and GnRH antagonist protocols in ART programs. METHODS This study was a retrospec...

purpose : cataract is one of the most common diseases of older ages and, at present, the leading cause of avoidable blindness in the world. along with the population growth, the rate of cataract surgeries is increasing in most countries worldwide. the number of cataract operations per million population per year is known as the cataract surgery rate (csr) and is one of the indicators introduced...

introduction: although hippocampus is the most famous brain area involved in temporal lobe epilepsy, hippocampal kindling (hk) develops very slowly. hence, rapid kindling is usually preferred to the traditional kindling and it is widely used. in this article we aimed at finding the optimal stimulus pattern, which yields the fastest hk rate. methods: stimulus patterns with different duration (2,...

An enhanced authentication key exchange protocol was proposed to exchange multiple session keys between two participants at a time. This paper shows that this enhanced protocol is insecure under the known session key attack, known long-term private key attack, signature forgery attack, and replay attack. This paper also proposes an enhanced and secure key agreement protocol for exchanging multi...
