BACKGROUND: The pathogenesis of post-transplantation erythrocytosis (PTE) is not well understood and appears to be multifactorial. Our hypothesis in this study was that several factors, including toxicity of calcineurin inhibitor, immunologic factors, and chronic allograft nephropathy, can trigger local tissue hypoxia in peritubular interstitium, which is where production of erythropoietin (EPO) takes place. This local interstitial tissue hypoxia can cause an increase in renal EPO production, which induces the development of PTE...

OBJECTIVE: This study sought to examine the effect of changing TSH threshold recommendations from 2.5 to 4 mIU/L before fertility therapy on the prevalence of early gestational subclinical hypothyroidism (SCH) (TSH2 >2.5 mIU/L) and to evaluate implications on progression to clinical pregnancy (defined as detection of cardiac activity on ultrasound). METHODS: A retrospective chart review was performed in an academic fertility clinic on all patients with a measured pre-treatment TSH (TSH1) and positive beta-human chorionic gonadotropin following fertility treatment...

INTRODUCTION: Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive trait; it often requires some interventions with general anesthesia because of the accompanied complications. CASE PRESENTATION: We report a 19-year-old girl with palmoplantar hyperkeratosis who presented total loss of her teeth. She was candidate to mandibular bone graft and lower jaw dental implants under general anesthesia. CONCLUSIONS: There are only a few studies about perioperative management of these patients; however, the anesthesiologists should consider a few important issues during pre-operative and intra-operative management...

Angiomyolipoma (AML) and oncocytoma are uncommon benign neoplasms of the kidney which their simultaneous occurrence in the same kidney is extremely rare. This study reports a 60-year-old diabetic woman with the rare simultaneous occurrence of three renal masses. Histologic evaluation revealed two angiomyolipomas and one oncocytoma within the same kidney, in a background of histologic features of diabetic nephropathy. Renal angiomyolipoma and oncocytoma are uncommon neoplasms, and their simultaneous occurrence in the same kidney is extremely rare...

Adult T-cell leukemia-lymphoma (ATL) is a mature T-cell malignancy associated with human T-cell leukemia virus type I (HTLV-1) infection. Japan is the most endemic country for HTLV-1 and ATL in the world. Recent nationwide studies of Japanese blood donors reported that HTLV-1 carriers spread from endemic areas to non-endemic areas. Therefore, the latest information on nationwide epidemiological and clinical data for ATL is necessary to guide clinical practice. We conducted a multicenter, hospital-based survey of newly diagnosed ATL patients from 2010 to 2011...

Time is a fundamental dimension, but millisecond-level judgments sometimes lead to perceptual illusions. We previously introduced a "time-shrinking illusion" using a psychological paradigm that induces auditory temporal assimilation (ATA). In ATA, the duration of two successive intervals (T1 and T2), marked by three auditory stimuli, can be perceived as equal when they are not. Here, we investigate the spatiotemporal profile of human temporal judgments using magnetoencephalography (MEG). Behavioural results showed typical ATA: participants judged T1 and T2 as equal when T2 - T1 ≤ +80 ms...

Sensitive and fast optical imaging is needed for scientific instruments, machine vision, and biomedical diagnostics. Many of the fundamental challenges are addressed with time stretch imaging, which has been used for ultrafast continuous imaging for a diverse range of applications, such as biomarker-free cell classification, the monitoring of laser ablation, and the inspection of flat panel displays. With frame rates exceeding a million scans per second, the firehose of data generated by the time stretch camera requires optical data compression...

Scimitar syndrome represents a rare variant of partial anomalous pulmonary venous connection with right lung hypoplasia, dextrocardia, and concomitant airway-vessel abnormalities. Surgical correction is preferred in symptomatic patients or in patients with increased left-to-right shunt. In this report, the first case of scimitar syndrome with dual arterial supply and venous drainage to be treated with thoracoscopic approach is presented.

BACKGROUND: Patients with aspirin-exacerbated respiratory disease (AERD) are distinguished from patients with aspirin-tolerant asthma (ATA) by significantly higher baseline concentrations of urinary leukotriene E4 (uLTE4). However, an overlap between the individual values of the groups exists. OBJECTIVE: The objective of this study was to estimate the discriminative value of uLTE4 concentration in differentiating between patients with AERD and patients with ATA and evaluate the diagnostic accuracy of uLTE4 measurement alone and added to clinical parameters to predict AERD diagnosis in patients with asthma...

Temperature compensation is a striking feature of the circadian clock. Here we investigate biochemical mechanisms underlying temperature-compensated, CKIδ-dependent multi-site phosphorylation in mammals. We identify two mechanisms for temperature-insensitive phosphorylation at higher temperature: lower substrate affinity to CKIδ-ATP complex and higher product affinity to CKIδ-ADP complex. Inhibitor screening of ADP-dependent phosphatase activity of CKIδ identified aurintricarboxylic acid (ATA) as a temperature-sensitive kinase activator...

Sandeep Panda, Ata Akcil, Srabani Mishra, Ceren Erust
Simultaneous multi-metal leaching from industrial pyrite ash is reported for the first time using a novel bioreactor system that allows natural diffusion of atmospheric O2 and CO2 along with the required temperature maintenance. The waste containing economically important metals (Cu, Co, Zn & As) was leached using an adapted consortium of meso-acidophilic Fe(2+) and S oxidising bacteria. The unique property of the sample supported adequate growth and activity of the acidophiles, thereby, driving the (bio) chemical reactions...

BACKGROUND: Abnormal joint motion has been linked to joint arthrosis after anterior cruciate ligament (ACL) reconstruction. However, the relationships between the graft properties (ie, structural and anatomic) and extent of posttraumatic osteoarthritis are not well defined. HYPOTHESES: (1) The structural (tensile) and anatomic (area and alignment) properties of the reconstructed graft or repaired ACL correlate with the total cartilage lesion area 1 year after ACL surgery, and (2) side-to-side differences in anterior-posterior (AP) knee laxity correlate with the total cartilage lesion area 1 year postoperatively...

INTRODUCTION: Children often present to the emergency department (ED) with minor conditions such as fever and have persistently abnormal vital signs. We hypothesized that a significant portion of children discharged from the ED would have abnormal vital signs and that those discharged with abnormal vital signs would experience very few adverse events. METHODS: We performed a retrospective chart review encompassing a 44-month period of all pediatric patients (aged two months to 17 years) who were discharged from the ED with an abnormal pulse rate, respiratory rate, temperature, or oxygen saturation...
