Decreased expression of the TCR ζ-chain has been reported in several autoimmune, inflammatory, and malignant diseases, suggesting that ζ-chain downregulation is common at sites of chronic inflammation. Although ζ-chain is critically important in T lymphocyte activation, the mechanism of the decreased ζ-chain expression is less clear. Src-like adaptor protein (SLAP) is a master regulator of T ce...

OBJECTIVES Upon onset of acute type A aortic dissection, the aortic true lumen generally becomes fixed around the supra-aortic branches in the greater curvature and Botallo's ligament in the lesser curvature of the aortic arch. Therefore, the pathways of the false lumen through the arch can be categorized as anterior, bilateral and posterior. We investigated the relationship between a false lum...

It has previously been reported that in resting T-lymphocytes the protein tyrosine kinase p59 constitutively co-precipitates with four phosphoproteins of 43, 55, 85, and 120 kDa, respectively. We have recently cloned the 55-kDa protein that was termed Src kinase-associated phosphoprotein of 55 kDa (SKAP55). Here we demonstrate that the recently characterized SH2-domain-containing leukocyte prot...

Superior labral anterior posterior (SLAP) tears are an abnormality of the superior labrum usually centered on the attachment of the long head of the biceps tendon. Tears are commonly caused by repetitive overhead motion or fall on an outstretched arm. SLAP lesions can lead to shoulder pain and instability. Clinical diagnosis is difficult thus imaging plays a key diagnostic role. The normal anat...

This paper proposes an efficient segmentation algorithm to extract multiple fingerprints from a four slap fingerprint image. The proposed algorithm divides each slap image into non-overlapping square blocks and identifies foreground and background blocks using average pixel intensity in that block. Blocks are joined to find the foreground block’s connected components. Finally clusters containin...

Background: Meniscus tear is a common finding in patients with anterior cruciate ligament (ACL) injury and may affectthe natural history of the injury and the outcomes of treatment. In the current study, the characteristics of meniscus tearsin patients who underwent arthroscopic ACL reconstruction were investigated.Methods: The hospital records of 1022 patients were reviewed. ...

BACKGROUND Multiple options exist for repair of superior labral tears. PURPOSE To compare commonly used fixation techniques for superior labral tears. STUDY DESIGN Biomechanical cadaveric study. METHODS A comparison of the initial strengths of fixation for type II superior labral anterior posterior (SLAP) lesions was performed in three cadaveric shoulder groups, each containing seven spec...

Patients were divided in 4 groups (Habermayer classification) and evaluated for an unstable LHBT:10 patients had superior gleno-humeral ligament (SGHL) tear (Type I),16 patients SGHL and supraspinatus (SSP) tendon tears (Type II),21 patients SGHL and subscapularis (SSC) tendon tears (Type III) and 23 patients SGHL, SSP and SSC tears (Type IV). At arthroscopy 2 patients were negative,8 patients ...

objective: studies reported conflicting results’ regarding the status of depression and glycemic control in patients with type ii diabetes(t2dm), therefore, this study was performed to determine the relationship between depression and glycemic control in t2dm patients. materials and methods: this cross-sectional study was performed on 150 t2dm patients referred to yazd diabetes research center,...

tyrosinemia type ii is a rare autosomal recessive disorder wich can present itself with recurrent epithelial keratitis, hyperkeratotic skin lesions and mental retardation. this article reports the rare occurrence of this disease in both offsprings (two brothers) of a family (consanguinous'marriage) who were managed with a lowprotein diet and a special regimen.
