In vitro selection of antibodies from large repertoires of immunoglobulin (Ig) combining sites using combinatorial libraries is a powerful tool, with great potential for generating in vivo scavengers for toxins. However, addition of a maturation function is necessary to enable these selected antibodies to more closely mimic the full mammalian immune response. We approached this goal using quantum mechanics/molecular mechanics (QM/MM) calculations to achieve maturation in silico. We preselected A17, an Ig template, from a naïve library for its ability to disarm a toxic pesticide related to organophosphorus nerve agents...

We report a patient with resistance to thyroid hormone beta caused by a novel <i>THRB</i> gene mutation and coexisting pituitary microadenoma. A 41-year-old Thai woman presented with elevated serum thyroid hormone levels and non-suppressed TSH. MRI showed a 4x2-mm pituitary adenoma. Five of her relatives had similar thyroid tests abnormalities, but a sister had Graves' disease. TPO and TG antibodies were positive in all affected family members except for a 4.5 year-old. Lack of thyrotoxic symptoms and TSH suppression by T3, indicated incidentaloma rather than a TSH-secreting pituitary adenoma...

The increasing detection of papillary thyroid microcarcinoma (PTMC) has created management dilemmas. To clarify the clinical significance of postsurgery stimulated thyroglobulin (ps-Tg) in PTMC who undergo thyroidectomy and radioactive iodine (RAI), we retrospectively reviewed the 358 PTMC patients who were treated with RAI and followed up in our hospital. Those with an excessive anti-Tg antibody, ultrasound-detected residual were excluded, thereby resulting in the inclusion of 280 cases. Their clinical and histopathological information and clinical outcomes were collected and summarized...

Rectal neuroendocrine tumor (RNET) lymphovascular invasion (LVI) is regarded as an important predictor of nodal metastasis after endoscopic resection (ER). However, little is known about the frequency of immunohistochemical detection of LVI in RNETs. This study was performed to establish the actual detection of LVI rate in RNETs ≤10 mm and to evaluate associated clinical outcomes. We retrospectively reviewed the records for 98 consecutive patients treated by ER with a total of 102 RNETs ≤10 mm. Tissue sections were labeled with hematoxylin-eosin (HE) stain, the D2-40 monoclonal antibody to evaluate lymphatic invasion, and Elastica van Gieson (EVG) stain to detect venous invasion...

BACKGROUND: Gastric foveolar hyperplastic polyps (GFHPs) are common findings in clinical practice. GFHPs commonly arise in a background of chronic atrophic gastritis, including autoimmune gastritis (type A gastritis), and have a potential risk of malignant transformation. CASE PRESENTATION: In 2005, a 55-year-old Japanese woman underwent upper endoscopy at another hospital and was found to have a pedunculated polyp (10 mm in diameter) on the greater curvature of the lower gastric body...

PURPOSE: High glucose stimulates peritoneal inflammation and extracellular matrix accumulation in human peritoneal mesothelial cells (HPMCs). However, the roles of Toll-like receptor 4 (TLR4) and TLR2 in high-glucose-induced inflammation and fibrosis in peritoneal dialysis (PD) remain unclear. This study aimed to evaluate the effect of high glucose on TLR2 and TLR4 expression in HPMCs and to assess their impact on peritoneal inflammatory and fibrosis markers. METHODS: Using cultured HPMCs, TLRs expression by high-glucose (50 mM) stimulation was assessed by quantitative real-time PCR...

The genomic region of Grapevine fanleaf virus (GFLV) encoding the movement protein (MP) was cloned into pET21a and transformed into Escherichia coli strain BL21 (DE3) to express the protein. Induction was made with a wide range of isopropyl-β-D-thiogalactopyranoside (IPTG) concentrations (1, 1.5, and 2 mM) each for duration of 4, 6, or 16 h. However, the highest expression level was achieved with 1 mM IPTG for 4 h. Identity of the expressed protein was confirmed by sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) followed by Western blotting...

Two solitary and minute tumors of 1 and 1.5 mm diameter were identified by microscopy in the left fourth mammary gland of a 13-year-old female Labrador Retriever dog, in addition to multiple mammary gland tumors. The former tumors were well circumscribed and were composed of small-to-large polyhedral neoplastic oncocytes with finely granular eosinophilic cytoplasm, and were arranged in solid nests separated by fine fibrovascular septa. Scattered lumina of variable sizes containing eosinophilic secretory material were evident...

Multiple myeloma (MM) is a hematologic cancer derived from malignant plasma cells within the bone marrow. Unlike most solid tumors, which originate from epithelial cells, the myeloma tumor is a plasma cell derived from the lymphoid cell lineage originating from a post-germinal B-cell. As such, the MM plasma cell represents an integral component of the immune system in terms of both antibody production and antigen presentation, albeit not efficiently. This fundamental difference has significant implications when one considers the implications of immunotherapy...

Treatment for myeloma has dramatically changed over the past decade, as has overall survival, due in large part to the development of new targeted agents. While proteasome inhibitors and immunomodulatory agents have contributed to improved outcomes, additional new options remain an unmet medical need. Classes of emerging agents include those targeting epigenetics, such as histone deacetylase inhibitors, monoclonal antibodies, and other emerging targets, such as kinesin spindle protein (KSP) inhibitors, cyclin dependent kinase (CDK) inhibitors, and nuclear protein export inhibitors...

Survival outcomes of patients with Multiple Myeloma (MM) have improved over the last decade due to the introduction of novel agents such as the immunomodulatory drugs thalidomide, lenalidomide (Len) and pomalidomide, and the proteasome inhibitors bortezomib (BTZ) and carfilzomib [1, 2]. However, despite these major advances, MM remains largely incurable and almost all patients relapse and require additional therapy [3]. The successful introduction of next generation novel agents including oral proteasome inhibitors, deacetylase inhibitors, and especially monoclonal antibodies as part of immunotherapy promises to further improve outcome...

Treatment approaches for newly diagnosed myeloma have changed considerably during the past decade, along with a better understanding of the disease heterogeneity. Availability of new drug classes such as proteasome inhibitors and immunomodulatory drugs, and use of these drugs in combinations have led to higher response rates and deeper responses in the vast majority of patients with newly diagnosed myeloma. In addition to improved efficacy, these regimens are tolerated better than those with conventional chemotherapy drugs, which have reduced the early mortality seen in MM, while allowing for successful stem cell collection in patients undergoing stem cell transplant consolidation...

Multiple myeloma (MM) is a disease of the elderly, with a median age at diagnosis of approximately 70 years old, and more than 30 % of patients aged >75 years. This latter and very elderly population is going to significantly rise in the near future given the increase in life expectancy in Western countries, and, most importantly, global health status of elderly patients is improving, justifying appropriate treatments. Changes in treatment paradigm from the old melphalan-prednisone regimen used since the 1970s to its use as a backbone in a nontransplant setting since the late 1990s have highlighted different subgroups in elderly MM...

Assessment of minimal residual disease (MRD) is becoming standard diagnostic care for potentially curable neoplasms such as some acute leukemias as well as chronic myeloid and lymphocytic leukemia. Although multiple myeloma (MM) remains as an incurable disease, around half of the patients achieve complete remission (CR), and recent data suggests increasing rates of curability with "total-therapy-like" programs. This landscape is likely to be improved with the advent of new antibodies and small molecules. Therefore, conventional serological and morphological techniques have become suboptimal for sensitive evaluation of highly effective treatment strategies...
