Low-Defect, Purified, Narrowly (n,m)-Dispersed Single-Walled Carbon Nanotubes Grown from Cobalt-Incorporated MCM-41 (2007)

A mild, four-step purification procedure using NaOH reflux, HCl wash, and oxidation by 4 mol % molecular oxygen at 500 degrees C was developed to purify single-walled carbon nanotubes (SWCNTs) with narrow semiconducting (n,m) distribution produced from cobalt-incorporated MCM-41 (Co-MCM-41) in order to obtain bulk low-defect-density nanotubes. Three key features of Co-MCM-41 allow this mild purification technique: (1) ultrathin silica walls versus dense silica or other crystalline oxide supports are soluble in dilute NaOH aqueous solution, which avoids the damage to SWCNTs usually caused by using HF treatment to remove catalytic supports; (2) the small metallic particles are easily dissolved in HCl, a significantly milder chemical treatment compared to HF or HNO(3); (3) the high selectivity to SWCNTs with negligible multiwalled carbon nanotubes or graphite, which facilitates the removal of undesired carbon species by selective oxidation. The effectiveness of this purification procedure was evaluated by high-resolution transmission electron microscopy, scanning electron microscopy, Raman, UV-vis-NIR, and fluorescence spectroscopy, solution redox chemistry on fractionated (6,5) tubes, and SWCNT-based field effect transistor device performance. The results demonstrate that Co-MCM-41 catalyst not only provides tubes with narrow semiconducting (n,m) distribution but also allows a mild purification procedure and, therefore, produces SWCNTs with fewer defects.
Ocular melanin binding of drugs: in vitro binding studies combined to a pharmacokinetic model (2014)

Certain drugs accumulate into pigmented tissues due to their binding to melanin, a macromolecule inside pigmented cells. Melanin can affect the drug's pharmacokinetics by acting as a drug reservoir. Binding can also cause toxic effects by accumulating compounds to pigmented cells. This thesis focuses on ocular melanin. The literature review covers the most common methods used in the study of ocular melanin binding and concentrates on in vitro methods and the analysis and usability of the results in pharmacokinetic modeling. &#13;\n&#13;\nThe aim of the experimental part was to study melanin binding of a set of compounds in vitro with melanin isolated from the retinal pigment epithelium (RPE) and choroid of porcine eyes and with primary porcine RPE cells and then construct a pharmacokinetic model of melanin binding with STELLA® software and simulate it with the in vitro results. The compounds chosen for the study; nadolol, timolol, chloroquine, methotrexate, carboxydichlorofluorescein (CDCF) and dexamethasone, are small molecules with diverse physicochemical properties (octanol/water partitioning coefficient (logP), pKa, acid/base status). Some are also efflux substrates. The in vitro binding with melanin was studied at pH 7.4 and in addition at pH 5 for the acidic compounds, since the pH inside melanosomes where melanin is located is acidic. Porcine RPE cells were used to study the amount of uptake and rate of elimination of the set of compounds. The effect of efflux was also evaluated with a general efflux inhibitor probenecid. &#13;\n&#13;\nAll the basic compounds bound to melanin in vitro. The acidic compounds did not seem to bind at pH 7.4 but bound at pH 5. Chloroquine, as expected, had the highest binding. In the cell studies, the uptake of chloroquine was significant, at least partly due to melanin binding. The other compounds were taken into the cells to a much smaller extent. The efflux inhibitor did not seem to affect the results. The results of the binding study were used in the models constructed of melanin binding and cellular pharmacokinetics. The constructed model was a very simple one not taking into account many factors affecting cellular pharmacokinetics. The results of both the in vitro studies and the model give a good idea of the importance of melanin binding in ocular drug delivery. The model can be used in the future as a base for more comprehensive models of the effect of melanin binding on ocular pharmacokinetics.
Reversion in Hamster Cells Transformed by Rous Sarcoma Virus (1965)

Hamster cells of the BHK-21 line are transformable by Rous sarcoma virus (Schmidt-Ruppin strain). The transformed cells form colonies in agar suspension culture, grow on glass in disarray, and initiate tumors in hamsters and chickens, but extracts do not induce tumors in chickens. Chickens bearing tumors develop neutralizing antibody against the virus. Transformed cell clones give rise to "revertants" which form colonies on glass with cells oriented parallel to each other like the original uninfected cells. These revertants do not grow in agar or initiate chicken tumors, and they regain the original low transplantability of untransformed cells in hamsters.
A redesign of NEC2 using the object-oriented paradigm (1994)

In the days in which NEC2 was written, the software design philosophy in vogue was that of structural decomposition or procedural programming. Since the early 1980's computer programs of increasing complexity have been developed. These programs have highlighted deficiencies in the structural design technique. Primarily, these were that not enough support was given to data abstraction and information hiding. Programming methodologies such as object-based and object oriented methods were developed to overcome these shortcomings. This paper presents an object-oriented design of NEC2.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Representation of videokeratoscopic height data with Zernike polynomials (1995)

Videokeratoscopic data are generally displayed as a color-coded map of corneal refractive power, corneal curvature, or surface height. Although the merits of the refractive power and curvature methods have been extensively debated, the display of corneal surface height demands further investigation. A significant drawback to viewing corneal surface height is that the spherical and cylindrical components of the cornea obscure small variations in the surface. To overcome this drawback, a methodology for decomposing corneal height data into a unique set of Zernike polynomials is presented. Repeatedly removing the low-order Zernike terms reveals the hidden height variations. Examples of the decomposition-and-display technique are shown for cases of astigmatism, keratoconus, and radial keratotomy.
Costs of Autism Spectrum Disorders in the United Kingdom and the United States (2014)

The substantial direct and indirect economic effect of ASDs emphasizes the need to continue to search for effective interventions that make best use of scarce societal resources. The distribution of economic effect across many different service systems raises questions about coordination of services and sectors. The enormous effect on families also warrants policy attention.
The Glucagon‐Like Peptides (2006)

The glucagon-like peptides, GLP-1 and GLP-2, are cosecreted by intestinal L cells in response to nutrient ingestion. These peptides exert multiple effects on the gastrointestinal tract and pancreas to regulate the digestion, absorption, and assimilation of ingested nutrients, as well as providing feedback signals to the brain to modulate food intake. Tropic effects of GLP-1 and GLP-2 on their major peripheral target tissues, the beta cell and the intestinal epithelium, respectively, further enhance capacity for nutrient handling. When taken together, these findings demonstrate the diverse actions of the intestinal glucagon-like peptides to regulate nutrient homeostasis.
Diagnosis and treatment of craniosynostosis: Vilnius team experience (2015)

Background. The aim of the study was to review the methods of diagnosis of craniosynostosis and to analyze Vilnius (Lithuania) team experience of surgical treatment, surgical methods, aspects of anesthesia for patients with craniosynostosis and to present early results of surgical treatment. Materials and methods. A retrospective review of all patients with various types of craniosynostosis treated surgically during the period from 1 January 2009 to 31 December 2014 was performed. The following data were analyzed: age, type of deformity, surgical technique, surgical time, methods and course of anesthesia, intra- and postoperative complications, parents’ satisfaction, head form. Results. 24 patients were treated. The mean patient’s age at the time of surgery was 13.47 ± 8.2 months (min 7.3, max 46.5). Eliminating 3 patients whose age at the time of surgery was over 2 years (24.5, 29 and 46 months, respectively), the mean age of other 21 patients was 10.63 ± 1.77 (min 7.3, max 14.1) months. There were 9 cases of isolated trigonocephaly (37.5%), 7 cases of isolated scaphocephaly (29.2%), 7 cases of isolated anterior plagiocephaly (29.2%) and 1 case of posterior plagiocephaly combined with scaphocephaly (4.17%). All craniosynostoses were diagnosed clinically and diagnosis was confirmed with computed tomographic scanning. The median duration of surgery was 336.47 ± 59.63 minutes (min 308.13, max 364.82). The medium stay in the intensive care unit was 2.53 ± 1.28 days (min. 1.92, max 3.14). In all cases rigid osteosynthesis was performed. 2 children were diagnosed with syndromic craniofacial abnormalities. In 23 (95.83%) cases an intraoperative or postoperative blood transfusion was required. In 24 treated patients there was no mortality. During the early and late postoperative period no infections, CSF leakage and dural tears were observed. No neurological impairments or any signs of neurological deficits were observed by any of the treated patients. In all of cases parents were satisfied with their children’s changed head shape and aesthetic results. Conclusions. Cranioplasties for correction of craniosynostosis give good aesthetic results and this is a safe method, which helps to correct the head shape as well as improves the social adaptation of patients.
LaeA, a Regulator of Secondary Metabolism in Aspergillus spp (2004)

Secondary metabolites, or biochemical indicators of fungal development, are of intense interest to humankind due to their pharmaceutical and/or toxic properties. We present here a novel Aspergillus nuclear protein, LaeA, as a global regulator of secondary metabolism in this genus. Deletion of laeA (DeltalaeA) blocks the expression of metabolic gene clusters, including the sterigmatocystin (carcinogen), penicillin (antibiotic), and lovastatin (antihypercholesterolemic agent) gene clusters. Conversely, overexpression of laeA triggers increased penicillin and lovastatin gene transcription and subsequent product formation. laeA expression is negatively regulated by AflR, a sterigmatocystin Zn2Cys6 transcription factor, in a unique feedback loop, as well as by two signal transduction elements, protein kinase A and RasA. Although these last two proteins also negatively regulate sporulation, DeltalaeA strains show little difference in spore production compared to the wild type, indicating that the primary role of LaeA is to regulate metabolic gene clusters.
Therapy with anti-TNFα antibody enhances number and function of Foxp3+ regulatory T cells in inflammatory bowel diseases (2010)

These data demonstrate that anti-TNFα treatment of active IBD rapidly enhances the frequency of functional Foxp3(+) Tregs in blood and potentiates their suppressive function. This indicates that Treg potentiation may represent an unanticipated outcome of anti-TNFα biotherapy in IBD.
Autologous transplantation of canine long-term marrow culture cells genetically marked by retroviral vectors (1992)

Retroviral infection of bone marrow cells in long-term marrow cultures (LTMCs) offers several theoretical advantages over other methods for gene transfer into hematopoietic stem cells. To investigate the feasibility of this approach in a large animal model system, we subjected LTMCs from nine dogs to multiple infections with retrovirus containing the neomycin phosphotransferase gene (neo) during 21 days of culture. Feeder layers, cocultivation, polycations, and selection were not used. The in vitro gene transfer efficiency was 70% as determined by polymerase chain reaction amplification of neo sequences in colony- forming unit granulocyte-macrophage (CFU-GM) obtained from day-21 LTMCs. Day-21 LTMC cells were infused into autologous recipients with (four dogs) and without (three dogs) marrow-ablative conditioning. At 3 months posttransplant, up to 10% of marrow cells contained the neo gene. This percentage declined to 0.1% to 1% at 10 to 21 months posttransplant. Neo was also detected in individual CFU-GM, burst- forming unit-erythroid (BFU-E), and CFU-Mix progenitors derived from marrow up to 21 months postinfusion and in cultures of peripheral blood- derived T cells up to 19 months postinfusion. There was no difference in the percentage of neo-marked cells present when dogs that received marrow ablative conditioning were compared with dogs receiving no conditioning. Detection of neo-marked marrow cells almost 2 years after autologous transplantation in a large mammalian species shows that retroviral infection of marrow cells in LTMCs is a potentially nontoxic and efficient protocol for gene transfer. Further, our results suggest that marrow conditioning and in vivo selection pressure to retain transplanted cells may not be absolute requirements for the retention of genetically marked cells in vivo.
Preclinical SPECT/CT Imaging of αvβ6 Integrins for Molecular Stratification of Idiopathic Pulmonary Fibrosis (2013)

We have developed a highly sensitive, quantifiable, and noninvasive technique for measuring αvβ6 integrin levels within the lung. Measurement of αvβ6 integrins by SPECT/CT scanning has the potential for use in stratifying therapy for patients with pulmonary fibrosis.
Replication of tomato golden mosaic virus DNA B in transgenic plants expressing open reading frames (ORFs) of DNA A: requirement of ORF AL2 for production of single-stranded DNA (1989)

Tomato golden mosaic geminivirus has a genome of two single-stranded (ss) DNA components, A and B. An almost identical 'common' region in DNA A and DNA B is thought to contain sequence elements controlling replication and transcription. Hence investigation of sequences important for DNA replication by in vitro mutagenesis is complicated by possible effects on the transcription of genes for replication proteins. To overcome this problem, transgenic plants expressing open reading frames (ORFs) of DNA A from an enhanced cauliflower mosaic virus 35S RNA promoter were constructed and tested for their ability to support the replication of DNA B and DNA B mutants. The results show that plants transgenic for ORF AL1 are able to support the replication of the double-stranded (ds) forms of DNA B, but that ORF AL2 is required in addition to produce ssDNA B. ORFs AL3, BL1 or BR1 were not required for replication of ds or ssDNA B. To the best of our knowledge this is the first time that essential replication proteins of a geminivirus have been expressed constitutively from a plant genome without giving rise to replicating DNA A molecules, thereby allowing DNA B to replicate alone. Such transgenic plants should enable not only the mutational analysis of sequence elements within the replication origin region, but also the construction of a new generation of vectors for gene amplification in plants, based on a minimal virus replicon.
Antiretroviral Chemotherapy of Human Immunodeficiency Virus Infections Other Than With Azidothymidine (1992)

The intense research effort to develop molecules with the ability to inhibit the replication of human immunodeficiency virus type 1 was greatly facilitated by the elucidation of the viral life cycle. This information engendered the production of novel antiretroviral agents that inhibit human immunodeficiency virus type 1 at different points in its replicative cycle. The nucleoside analogue 3'-azido-2',3'-dideoxythymidine (azidothymidine) inhibits reverse transcriptase, and it was the first compound tested in patients with the acquired immunodeficiency syndrome. Considerable knowledge of the activity and toxicity of this class of drugs has accumulated. Less well-characterized compounds inhibit human immunodeficiency virus type 1 binding and absorption to target cells, prevent the expression of viral genetic material critical for the construction of new infectious viral progeny, and inhibit the posttranslational modification of viral polypeptides. In additional, biologic response, modifiers act to restore immune function by a number of diverse mechanisms. The ultimate goal is the discovery of compounds capable of inducing a complete and permanent remission of infection.
Combination therapy with interleukin-2 and antitumor monoclonal antibodies. (1997)

These studies have demonstrated the feasibility of concurrent administration of rIL-2 with the mouse/human chimeric ch14.18 mAb. Although the early pilot studies were conducted in patients with bulky disseminated disease, this approach may be more effective in patients with minimal residual disease. Further refinement of the reagents and phase II and III trials will be necessary to evaluate fully the safety and efficacy of this immunotherapeutic approach.
Fabrication of Biodegradable Polymer Foams for Cell Transplantation and Tissue Engineering (2003)

Organ transplantation has been successful since the early 1960s as a result of the success in immunologic suppression in the clinical setting (1), and has saved, and is continuing to save, countless lives, but is far from a perfect solution to tissue losses or organ failures. By far the most serious problem facing transplantation is donor scarcity. Approximately 30,000 Americans need liver transplantation each year, but only about 10% of the patients have the chance to receive a donated liver transplant (2). There is a total of approx 100,000 people in the United States with transplants, but there are more than 1 million with biomedical implants (3). Tissue engineering and cell transplantation are fields emerging to resolve the missing tissue and organ problems.
Macrophage Heterogeneity of Culprit Coronary Plaques in Patients With Acute Myocardial Infarction or Stable Angina (2013)

We investigated the polarization states of macrophages in coronary atherectomy tissues retrieved from patients with acute myocardial infarction (AMI, n = 52) or stable angina pectoris (SAP, n = 22). The specimens were analyzed immunohistochemically using antibodies specific to CD11c (M1 marker), CD206 (M2 marker), and to markers of endothelial cells, macrophages, and smooth muscle cells. Baseline characteristics were similar in the 2 groups. The proportion of areas immunopositive for α smooth muscle actin was similar, but those positive for CD31 and CD68 were larger in the AMI group compared with the SAP group. In addition, AMI had significantly greater areas immunopositive for CD11c (P = .007) than did SAP, but CD206 (P = .102) positivity was not different in the 2 groups. In conclusion, M1 macrophage infiltration, not M2 macrophage infiltration, was increased in culprit plaques of patients with AMI. Macrophage heterogeneity may therefore be related to plaque instability.
Chimeric streptococcal plasmids and their use as molecular cloning vehicles in Streptococcus sanguis (Challis) (1980)

Chimeric plasmids, which were useful as cloning vehicles in a Streptococcus sanguis (Challis) host vector system, have been constructed. By using three different strategies of restriction endonuclease digestion and ligation, a deoxyribonucleic acid (DNA) fragment bearing an erythromycin resistance determinant was ligated in vitro to a phenotypially cryptic plasmid from Streptococcus ferus. Recombinant plasmids could be recovered after transformation of S. sanguis (Challis) with these preparations. Three useful chimeras were constructed. pVA680, 5.5 megadaltons in size, contained a single KpnI site into which passenger DNA may be spliced. pVA736, 5.0 megadaltons in size, contained single EcoRI, HindIII, and KpnI sites into which passenger DNA may be spliced. The EcoRI and KpnI sites of pVA736 may be used in combination with one another when ligating DNA into this plasmid. pVA738, 3.7 megadaltons in size, contained single HindIII and AvaI sites into which passenger DNA may be spliced. pVA680, pVA736, and pVA738 were stably maintained as multicopy plasmids in S. sanguis (Challis). None of them continued to replicate (amplify) in chloramphenicol-treated cells. By using pVA736 as a vector, we have cloned a chloramphenicol resistance determinant obtained from a large, conjugative streptococcal R plasmid. In addition, chromosomal DNA sequences from Streptococcus mutans have been inserted into pVA736 by using the KpnI-EcoRI site combination.
Centromere protein F and survivin are associated with high risk and a poor prognosis in colorectal gastrointestinal stromal tumours (2011)

The results suggest that centromere protein F and survivin are malignant behaviour markers for CRGISTs. The expression of centromere protein F or survivin points to a poor clinical outcome. Interfering with centromere protein F and/or survivin expression might be a potentially therapeutic strategy for treating malignant CRGISTs.
Gastroretentive drug delivery systems (2006)

A controlled drug delivery system with prolonged residence time in the stomach is of particular interest for drugs that i) are locally active in the stomach, ii) have an absorption window in the stomach or in the upper small intestine, iii) are unstable in the intestinal or colonic environment, or iv) exhibit low solubility at high pH values. This article gives an overview of the parameters affecting gastric emptying in humans as well as on the main concepts used to design pharmaceutical dosage forms with prolonged gastric residence times. In particular, bioadhesive, size-increasing and floating drug delivery systems are presented and their major advantages and shortcomings are discussed. Both single- and multiple-unit dosage forms are reviewed and, if available, results from in vivo trials are reported.
