In this study, the matrix-entrapment technique was adopted to immobilize a novel manganese peroxidase (MnP). Agarose beads developed from 3.0% agarose concentration furnished the preeminent immobilization yield (92.76%). The immobilized MnP exhibited better resistance to changes in the pH and temperature as compared to the free counterpart, with optimal conditions being pH 6.0 and 45°C. Thermal and storage stability characteristics were significantly improved after immobilization, and the immobilized-MnP displayed higher tolerance against different temperatures than free MnP state...

Tumor cells induce an immunosuppressive microenvironment which leads towards tumor immune escape. Understanding the intricacy of immunomodulation by tumor cells is essential for immunotherapy. Indoleamine 2,3-dioxygenase (IDO) is an immunosuppressive enzyme which mediates tumor immune escape in various cancers including hepatocellular carcinoma (HCC). IDO up-regulation in HCC may lead to recruitment of regulatory T-cells into tumor microenvironment and therefore inhibit local immune responses and promote metastasis...

In recent years, thymectomy has become a widespread procedure in the treatment of myasthenia gravis (MG). Likelihood of remission was highest in preoperative mild disease classification (Osserman classification 1, 2A). In absence of thymoma or hyperplasia, there was no relationship between age and gender in remission with thymectomy. In MG treatment, randomized trials that compare conservative treatment with thymectomy have started, recently. As with non-randomized trials, remission with thymectomy in MG treatment was better than conservative treatment with only medication...

The realization of acoustic devices analogous to electronic systems, like diodes, transistors, and logic elements, suggests the potential use of elastic vibrations (i.e., phonons) in information processing, for example, in advanced computational systems, smart actuators, and programmable materials. Previous experimental realizations of acoustic diodes and mechanical switches have used nonlinearities to break transmission symmetry. However, existing solutions require operation at different frequencies or involve signal conversion in the electronic or optical domains...

Relaxation and backwashing have become an integral part of membrane bioreactor (MBR) operations for fouling control. This study was carried out on real municipal wastewater to evaluate the influence of different operational strategies on membrane fouling at equivalent water yield. Four relaxation modes (MBR10+0, MBR10+1, MBR10+1.5 and MBR10+2) were tested to analyze membrane fouling behavior. For the optimization of relaxation modes, fouling rate in terms of trans-membrane pressure, hydraulic resistances and characteristics of fouling fractions were analyzed...

Castleman disease is a rare lymphoproliferative disorder with 2 distinctly defined clinical forms. While multicentric Castleman disease (UCD) poses a potential therapeutic challenge, unicentric variant has historically been considered curable with surgical resection. Hence, little is known to guide management of patients with UCD, refractory to surgical resection and combination chemotherapy. We present a case of a patient, negative for HIV and HHV-8, who had an unsuccessful surgical intervention and no response to radiotherapy and chemotherapy...

Localized laryngeal lymphoma is a rare entity with an incidence of less than 1% of all laryngeal neoplasms. Diffuse large B-cell lymphoma (DLBCL) is the most common type of laryngeal neoplasms. Here, we describe a case of a young 28-year-old female with large B-cell lymphoma who remained undiagnosed for a long time owing to a myriad of nonspecific presentation including "wheezing." Although primary laryngeal lymphomas constitute a diagnostic challenge since they are rare, one should have a high index of suspicion for lymphoma of the larynx in patients presenting with unresolved wheezing as it can present catastrophically with acute airway obstruction requiring immediate surgical intervention which was observed in this case...

Apart from its potent antioxidant property, recent studies have revealed that melatonin promotes PI3K/Akt phosphorylation following focal cerebral ischemia (FCI) in mice. However, it is not clear (i) whether increased PI3K/Akt phosphorylation is a concomitant event or it directly contributes to melatonin's neuroprotective effect, and (ii) how melatonin regulates PI3K/Akt signaling pathway after FCI. In this study, we showed that Akt was intensively phosphorylated at the Thr308 activation loop as compared with Ser473 by melatonin after FCI...
