Cytotoxic T lymphocyte hybridomas that mediate specific tumor-cell lysis in vitro. (1981)

Cytotoxic hybridomas were generated by polyethylene glycol-induced fusion of cytotoxic T lymphocytes (CTL) and BW5147 lymphoma cells. The CTL populations used for fusion were obtained from BALB/c (H-2d) mice primed with leukemia EL4 of C57BL/6 (H-2b) and restimulated either in vivo or in vitro. To circumvent possible CTL-mediated nonspecific lysis of BW5147 cells during fusion, the CTL were transiently inactivated by trypsin prior to fusion. Four cytolytically active hybridomas were obtained, cloned, and subcloned. Hybrid clones lysed all H-2b leukemic target cells tested but not lipopolysaccharide- or concavanalin A-stimulated C57BL/6 lymphoblasts or non-H2b target tumor cells. The mechanism of hybridoma-mediated killing of target cells in vitro appears to be similar to that of parental CTL, although some differences have been observed. The hybridomas appear to possess neither natural killing nor antibody-dependent cytolytic activity. Clones of hybrids propagated in culture for over 6 months without the addition of known external stimulus (i.e., independent of cell growth factor and antigen) exhibit specific lytic activity against H-2b tumor cells. Such autonomous hybridomas will provide a tool for studying the mechanism of CTL-mediated lysis and the nature of the CTL receptors.
Immunotherapy of hepatocellular carcinoma with small double-stranded RNA (2014)

The obtained results clearly demonstrate immunostimulatory and antimetastatic properties of the isRNAs in mice with HCC. Consequently, this short double-stranded RNA can be considered as a potential adjuvant for the therapy of HCC.
Broadly Neutralizing Human Immunodeficiency Virus Type 1 Antibody Gene Transfer Protects Nonhuman Primates from Mucosal Simian-Human Immunodeficiency Virus Infection (2015)

Broadly neutralizing antibodies (bnAbs) can prevent lentiviral infection in nonhuman primates and may slow the spread of human immunodeficiency virus type 1 (HIV-1). Although protection by passive transfer of human bnAbs has been demonstrated in monkeys, durable expression is essential for its broader use in humans. Gene-based expression of bnAbs provides a potential solution to this problem, although immune responses to the viral vector or to the antibody may limit its durability and efficacy. Here, we delivered an adeno-associated viral vector encoding a simianized form of a CD4bs bnAb, VRC07, and evaluated its immunogenicity and protective efficacy. The expressed antibody circulated in macaques for 16 weeks at levels up to 66 g/ml, although immune suppression with cyclosporine (CsA) was needed to sustain expression. Gene-delivered simian VRC07 protected against simian-human immunodeficiency virus (SHIV) infection in monkeys 5.5 weeks after treatment. Gene transfer of an anti-HIV antibody can therefore protect against infection by viruses that cause AIDS in primates when the host immune responses are controlled.
Evaluation and Treatment of Young Adults with Femoro-Acetabular Impingement Secondary to Perthes' Disease (2006)

Hip pain and loss of motion in young adults with previous Legg-Calve-Perthes-Disease may be caused by anterior femoro-acetabular impingement. Eleven patients (12 hips) with the chief complaint of groin pain and significant proximal femoral deformity were treated. Gadolinium-enhanced magnetic resonance arthrography in ten patients indicated labral injury and adjacent acetabular cartilage lesions in nine hips. A surgical dislocation of each hip confirmed that there was impingement induced intra-articular injury consistent with the pathology indicated on the MRI. Reshaping of the femoral head, with correction of the femoral head/neck offset, and treatment of the acetabular rim pathology was performed for each hip in conjunction with other procedures for the proximal femur. Correction of the impingement and increased range of motion could be visualized intra-operatively At a mean follow-up of 33 months, half of all patients were pain-free and all had improvement in pain compared with preoperatively Ten patients had an improved range of motion and two a slight decrease. No additional necrosis following the dislocation of the femoral head was seen.
Metabolic engineering of yeast to produce fatty acid-derived biofuels: bottlenecks and solutions (2015)

Fatty acid-derived biofuels can be a better solution than bioethanol to replace petroleum fuel, since they have similar energy content and combustion properties as current transportation fuels. The environmentally friendly microbial fermentation process has been used to synthesize advanced biofuels from renewable feedstock. Due to their robustness as well as the high tolerance to fermentation inhibitors and phage contamination, yeast strains such as Saccharomyces cerevisiae and Yarrowia lipolytica have attracted tremendous attention in recent studies regarding the production of fatty acid-derived biofuels, including fatty acids, fatty acid ethyl esters, fatty alcohols, and fatty alkanes. However, the native yeast strains cannot produce fatty acids and fatty acid-derived biofuels in large quantities. To this end, we have summarized recent publications in this review on metabolic engineering of yeast strains to improve the production of fatty acid-derived biofuels, identified the bottlenecks that limit the productivity of biofuels, and categorized the appropriate approaches to overcome these obstacles.

Treatment of Acute Rejection in Live Related Renal Allograft Recipients: A Comparison of Three Different Protocols (1997)

We present our experience on the comparison of three different modes of steroid therapy, oral prednisolone (OP), intravenous dexamethasone (IVDX) and intravenous methylprednisolone (IVMP) in the treatment of acute rejection (AR) in renal allograft recipients. Between January 1980 and January 1992, 206 patients underwent live related renal transplantation. Before 1990, all received prednisolone (PRED) and azathioprine (AZA) only. After 1990, patients were given PRED, AZA and cyclosporine (CsA). After 1 year, CsA was stopped and patients were converted to a two-drug regimen only. Of the 206 patients, 180 (87.4%) were male and mean age was 30.3+/-8.7 years (range 14-63). During the mean follow-up of 43.5 months, 178 episodes of AR were seen in 121 patients. Each episode was considered as a separate entrant in the study. Conventional immunosuppression was given in 151 episodes and 27 episodes were on triple-drug therapy. Diagnosis of AR was made by clinical, sonography, nuclear scan with or without graft biopsy evidence. Of the 178 AR, 110 (61.8%) were within 3 months, 36 (20.2%) were between 3 months and 1 year and 32 (18%) were after 1 year. OP was given in 11 cases while IVDX and IVMP were given in 48 and 119 cases respectively. Overall, 154 (86%) showed either a complete or partial response to antirejection therapy. Response to therapy was 91, 90 and 85% in OP, IVDX and IVMP groups respectively. There was no statistical difference in response rate in different groups. There was also no difference in side effects in three different groups. Our data suggest that it is the high dose of steroid rather than mode of therapy which is responsible for therapeutic benefit in treatment of AR.

Prediction of progression after radical nephrectomy for patients with clear cell renal cell carcinoma (2003)

In patients with clear cell RCC, tumor stage, regional lymph node status, tumor size, nuclear grade, and histologic tumor necrosis showed statistically significant associations with progression to metastatic RCC. The authors present a scoring algorithm based on these features that can be used to predict disease progression after patients undergo radical nephrectomy for clinically localized clear cell RCC.

The heparin binding PECAM-1 adhesion molecule is expressed by CD34+ hematopoietic precursor cells with early myeloid and B-lymphoid cell phenotypes (1993)

The platelet-endothelial cell adhesion molecule-1 (PE-CAM-1), defined by the CD31 monoclonal antibody (MoAb), was initially described as a cell-cell adhesion molecule mediating both homotypic and heterotypic adhesion. In this report, we show that enriched CD34+ human hematopoietic progenitor cell populations, containing early myeloid, erythroid, and multipotential progenitor cells, are CD31+. Analyses of CD34+ cell lines representing early myeloid, multipotential, and pre- pre-B-lymphoid progenitors indicate that precursors of both myeloid and B-lymphoid cells express PECAM-1 at high levels. Three-color flow- cytometric analyses also show that normal human bone marrow CD31+ CD34+ subsets coexpress myeloid (CD33) or B-lymphoid (CD19, CD10) markers. Except for the monocytic cell line, U937, all CD34- cell lines tested, which represent more mature stages of the myeloid, erythroid, and lymphoid lineages, expressed substantially lower or negligible levels of PECAM-1. Western blotting studies indicated that the CD31 MoAb, JC/70A, detected molecules in the 120- to 140-kD molecular weight range on the monocytic CD34- CD33+ CD31+ cell line, U937; on the CD34+ CD31+ CD33+ CD19- multipotential/lymphomyeloid precursor cell lines, KG1 and KG1B; on the CD34+ CD31+ CD19+ CD10+ CD33- precursor pre-pre-B-cell line, MIK-ALL; and on a CD34(+)-enriched precursor cell population from normal human bone marrow. A single molecular weight species was generally observed with enriched membrane preparations, whereas two PECAM-1 molecules were present in whole-cell lysates of cell lines and the CD34+ bone marrow cell subset. Preliminary studies show that a proportion of the PECAM-1 molecules on the lymphomyeloid/multipotential progenitor cell line, KG1, and on the monocytic cell line, U937, binds to heparin-sepharose. A soluble form of PECAM-1 also binds heparin- sepharose. The high level of expression of PECAM-1 on CD34+ cells suggests that this glycoprotein may function as a heterotypic adhesion molecule, possibly mediating multipotential, myeloid, and early-B- lymphoid precursor cell interactions with stromal cells and extracellular matrix molecules via heparan sulfate proteoglycans. It may also act as a homotypic adhesion molecule by interacting with PECAM- 1 on bone marrow stromal macrophage-like cells and endothelial cells or on endothelial cells during stem/progenitor cell migration. Thus, this molecule has the potential importance of directing both lineage commitment and trafficking of early hematopoietic progenitor cells.
112-Gbit/s PDM-PAM4 transmission over 80-km SMF using digital coherent detection without optical amplifier (2016)

In this work, we experimentally demonstrated a 112 Gbit/s polarization-division-multiplexed (PDM) four-level pulse amplitude modulation (PAM4) transmission over 80-km single mode fiber (SMF) using digital coherent detection without optical amplifier and CD compensation for the short reach applications. Here, a signal-phase aided least-mean-square (SP-LMS) equalization algorithm is proposed to avoid the effects of carrier frequency offset and phase noise. Without additional carrier recovery algorithms, the PDM-PAM4 system shows good transmission performance. The received optical power (ROP) penalty is only about 0.2 dB after 80 km transmission comparing to back-to-back (BTB) transmission. A receiver sensitivity of -20dBm (at 7% FEC limit) can be reached after 80-km transmission.
Inhibition of Homophilic Interactions and Ligand Binding of the Receptor for Advanced Glycation End Products by Heparin and Heparin-Related Carbohydrate Structures (2018)

<b>Background:</b> Heparin and heparin-related sulphated carbohydrates inhibit ligand binding of the receptor for advanced glycation end products (RAGE). Here, we have studied the ability of heparin to inhibit homophilic interactions of RAGE in living cells and studied how heparin related structures interfere with RAGE⁻ligand interactions. <b>Methods:</b> Homophilic interactions of RAGE were studied with bead aggregation and living cell protein-fragment complementation assays. Ligand binding was analyzed with microwell binding and chromatographic assays. Cell surface advanced glycation end product binding to RAGE was studied using PC3 cell adhesion assay. <b>Results:</b> Homophilic binding of RAGE was mediated by V₁- and modulated by C₂-domain in bead aggregation assay. Dimerisation of RAGE on the living cell surface was inhibited by heparin. Sulphated K5 carbohydrate fragments inhibited RAGE binding to amyloid β-peptide and HMGB1. The inhibition was dependent on the level of sulfation and the length of the carbohydrate backbone. α-d-Glucopyranosiduronic acid (glycyrrhizin) inhibited RAGE binding to advanced glycation end products in PC3 cell adhesion and protein binding assays. Further, glycyrrhizin inhibited HMGB1 and HMGB1 A-box binding to heparin. <b>Conclusions:</b> Our results show that K5 polysaccharides and glycyrrhizin are promising candidates for RAGE targeting drug development.
Chondrogenic Differentiation of Cultured Human Mesenchymal Stem Cells from Marrow (1998)

In the adult human, mesenchymal stem cells (MSCs) resident in bone marrow retain the capacity to proliferate and differentiate along multiple connective tissue lineages, including cartilage. In this study, culture-expanded human MSCs (hMSCs) of 60 human donors were induced to express the morphology and gene products of chondrocytes. Chondrogenesis was induced by culturing hMSCs in micromass pellets in the presence of a defined medium that included 100 nM dexamethasone and 10 ng/ml transforming growth factor-beta(3) (TGF-beta(3)). Within 14 days, cells secreted an extracellular matrix incorporating type II collagen, aggrecan, and anionic proteoglycans. hMSCs could be further differentiated to the hypertrophic state by the addition of 50 nM thyroxine, the withdrawal of TGF-beta(3), and the reduction of dexamethasone concentration to 1 nM. Increased understanding of the induction of chondrogenic differentiation should lead to further progress in defining the mechanisms responsible for the generation of cartilaginous tissues, their maintenance, and their regeneration.
Measurement of Hardness at Indentation Depths as Low as 20 Nanometres (1985)

Hardness as a function of depth is examined over a wide range of depths in gold, nickel, lithium fluoride (LiF), and silicon. To examine hardness in very shallow indents (100 nm), a special hardness tester with 2.5-μN load resolution and 0.2-nm indenter displacement resolution was used. The tester monitors the load continuously as the load is applied and removed. The hardness is calculated using the depth measurements. Images of indents in the scanning electron microscope (SEM) and transmission electron microscope (TEM) are used to check that the expected contact areas are achieved. It is shown that the contact area can be calculated if elastic effects are accounted for. The loading and unloading portions of the curves are discussed in detail. Attention is paid to the mechanisms of hardness changes with depth and the effects of elastic recovery on contact area measurement.
Microangiographic assessment of collateral vessel formation following direct gene transfer of vascular endothelial growth factor in rats (1997)

Pyridyl Derivatives of Benzaldehyde as Potential Antisickling Agents (2008)

Compounds that bind to sickle hemoglobin (Hb S) producing an allosteric shift to the high-affinity Hb S that does not polymerize are being developed to treat sickle cell anemia (SCA). In this study, three series of pyridyl derivatives of substituted benzaldehydes (Classes I-III) that combine structural features of two previously determined potent antisickling agents, vanillin and pyridoxal, were synthesized. When analyzed with normal human whole blood, the compounds form Schiff-base adducts with Hb and left shift the oxygen equilibrium curve (OEC) to the more soluble high-affinity Hb, more than vanillin or pyridoxal. Generally, Class-I compounds with an aromatic aldehyde located ortho to the pyridyl substituent are the most potent, followed by the Class-II compounds with the aldehyde at the meta-position. Class-III compounds with the aldehyde at the para position show the weakest activity. The structure-activity studies of these pyridyl derivatives of substituted benzaldehydes demonstrate significant allosteric potency that may be useful for treating SCA.

Decorin Protein Core Inhibits in Vivo Cancer Growth and Metabolism by Hindering Epidermal Growth Factor Receptor Function and Triggering Apoptosis via Caspase-3 Activation (2006)

Decorin is not only a regulator of matrix assembly but also a key signaling molecule that modulates the activity of tyrosine kinase receptors such as the epidermal growth factor receptor (EGFR). Decorin evokes protracted internalization of the EGFR via a caveolar-mediated endocytosis, which leads to EGFR degradation and attenuation of its signaling pathway. In this study, we tested if systemic delivery of decorin protein core would affect the biology of an orthotopic squamous carcinoma xenograft. After tumor engraftment, the animals were given intraperitoneal injections of either vehicle or decorin protein core (2.5-10 mg kg(-1)) every 2 days for 18-38 days. This regimen caused a significant and dose-dependent inhibition of the tumor xenograft growth, with a concurrent decrease in mitotic index and a significant increase in apoptosis. Positron emission tomography showed that the metabolic activity of the tumor xenografts was significantly reduced by decorin treatment. Decorin protein core specifically targeted the tumor cells enriched in EGFR and caused a significant down-regulation of EGFR and attenuation of its activity. In vitro studies showed that the uptake of decorin by the A431 cells was rapid and caused a protracted down-regulation of the EGFR to levels similar to those observed in the tumor xenografts. Furthermore, decorin induced apoptosis via activation of caspase-3. This could represent an additional mechanism whereby decorin might influence cell growth and survival.
Improvement of Degradation at Elevated Temperature and at High State-of-Charge Storage by ZrO[sub 2] Coating on LiCoO[sub 2] (2006)

A uniform coating on cathode materials for rechargeable lithium batteries was applied by a spray coating technique. The cells showed improved cycle performance and better durability of storing the cell (calendar life) under a high-voltage charging condition (4.2 V-313 K). X-ray diffraction and calorimetric study revealed that no marked change was observed in the bulk properties, such as crystal structure and phase transition, in the cathode during charge and discharge. The suppression of the increase of cathode/electrolyte interfacial impedance was observed by coating. Thus, the improved electrochemical performance in the higher voltage region is ascribed to the stabilization of the interface between the cathode and electrolyte materials.
