Correct assembly of thin filaments composed of actin and actin-binding proteins is of crucial importance for properly functioning muscle cells. Tropomyosin (Tpm) mediates the binding of tropomodulin (Tmod) and leiomodin (Lmod) at the slow-growing, or pointed, ends of the thin filaments. Together these proteins regulate thin filament lengths and actin dynamics in cardiac muscle. The K15N mutation in the TPM1 gene is associated with familial dilated cardiomyopathy (DCM) but the effect of this mutation on Tpm's function is unknown...

Renal cell carcinoma (RCC) is a common malignancy. Metastases can be seen both synchronously, at the time of diagnosis, and metachronously during follow-up. At the time of diagnosis, 23% of the patients have metastatic disease. and 25% of patients will develop metastasis during follow-up period after nephrectomy. Nearly 80% of them develop within the first 5 years. However late metastasis of RCC have been also reported within the postoperative 10 years in the literature. For metastatic lesions, if surgically feasible, metastasectomy, and targeted pharmaceutical agents have been recommended...

BK viras is a human polyoma viras. It is acquired in early childhood and remains life-long latent in the genitourinary system. BK virus replication is more common in receiving immunosuppressive therapy receiving patients and transplant patients. BK virus could cause hemorrhagic cystitis in patients with allogeneic stem cell transplantation. Hemorrhagic cystitis is a serious complication of hematopoietic stem cell transplantation. Hemorrhagic cystitis could cause morbidity and long stay in the hospital. Diagnosis is more frequently determined by the presence of BK virus DNA detected with quantitative or real-time PCR testing in serum or plasma and less often in urine...

A typical microfluidic device sorts, captures or fractionates sample constituents by exposing them to discriminating microenvironments. Direct electronic acquisition of such manipulation by a network of integrated sensors can provide a fast, integrated readout, replacing otherwise required microscopy. We have recently introduced a sensor technology, Microfluidic CODES, which allows us to multiplex resistive pulse sensors on a microfluidic device. Microfluidic CODES employs a network of micromachined coplanar electrodes such that particles passing over these electrodes produce distinguishable code sequences...

Fronto-orbital advancement using distraction techniques involves the dura left attached to the osteotomized bone segment to avoid dead space formation and dural injury, whereas it is impossible to reshape the supraorbital bar and the frontal bone complex, when necessary. Our approach combines advantageous parts of conventional and distraction osteogenesis techniques as remodel and distract the supraorbital bar and frontal bone complex as a free bone graft. Twenty-seven patients either being syndromic and nonsyndromic craniosynostosis, with at least 3 years of follow-up were reviewed in this study...

The phytoremediation by using of green plants in the removal of environmental pollutant is an environment friendly, green technology that is cost effective and energetically inexpensive. By using Agrobacterium-mediated gene transfer, we generated transgenic Arabidopsis plants ectopically expressing mercuric transport protein gene (merT) from Pseudomonas alcaligenes. Compared with wild-type (WT) plants, overexpressing PamerT in Arabidopsis enhanced the tolerance to HgCl2. Further results showed that the enhanced total activities or corresponding transcripts of antioxidant enzymes, including superoxide dismutase (SOD), catalase (CAT) and guaiacol peroxidase (POD) were observed in transgenic Arabidopsis under HgCl2 stress...
