Patenting Medical Procedures: A Search For A Compromise Between Ethics And Economics, Beata Gocyk-Farber

Cardozo Law Review

When doctor Samuel Pallin, an Arizona ophthalmologist, brought an infringement suit for his patent covering the "stitchless" incision in cataract surgery, he probably did not expect that he would provoke one of the most emotional patent debates in history. Physicians across the country expressed condemnation of medical process patents, calling such patents "horrendous" and warning that Dr. Pallin's victory may have "profoundly devastating and mind-boggling consequences" for medical science. The resonance in the medical community was so strong that the American Medical Association House of Delegates passed a resolution "vigorously" condemning the patenting of medical and surgical procedures and promising …

Combining Ability Of Resistance To The Sorghum Shootfly, Atherigona Soccata And Stemborer Chilo Partellus In Grain Sorghum, Sorghum Bicolor, A. A. Elbadawi, A. M. Nour, R. S. Pathak

All Peer-Reviewed Publications

Combining ability of resistance to the sorghum shootfly, Atherigona soccata and spotted stemborer, Chilo partellus in grain sorghum was analysed on a seven-parents diallel in a field trial at the ICIPE Mbita Point Field Station, western Kenya during the 1990 long rainy season. Lines with best performance for each of the four measured resistance parameters were also found to be the best general combiners. Resistance to leaf damage and number of holes/metre were controlled by additive gene effects whereas resistance to deadheart and stem tunnelling were controlled by additive and non-additive gene effects. Parents IS-1044, IS-12308 and IS-2269 with their …

Les Inhibiteurs Des Facteurs Humoraux Chez Les Criquets Migrateurs, Schistocerca Gregaria Et Locusta Migratoria: Perspectives D'Utilisation Dans La Lutte Biologique, D. Dakouo, S. Essuman, S. K. Raina, M. Bréhélin, Latifa Drif

All Peer-Reviewed Publications

Haemolymph from the locusts Schistocercagregaria and Locustamigratoria contains humoral factors such as lectin and phenoloxidase system. In vitro studies demonstrated that phenoloxidase system can be activated by LPS, laminarin, Malamoeba locustae cysts, trypsin and methanol. Haemolymph showed agglutination activity for mammalian erythrocytes and protozoa (M. locustae, Leishmania major and Trypanosoma brucei). A purified lectin was isolated fromhaemolymphby affinity chromatography. Analysis by SDS-PAGE gave a single band at 80 kD while on native PAGE, it gave a single band at 650 kD. Inhibitors of the two humoral factors were investigated. Lectin activity was inhibited by nitrophenyl a D-galactopyranoside in both cases …

Progeny Production And Sex Ratios Of Field Populations Of The Parasitoids Cotesia Flavipes And Cotesia Sesamiae Reared From Gramineous Stemborers In Coastal Kenya, Charles O. Omwega, William A. Overholt

All Peer-Reviewed Publications

Progeny production and sex ratios of the parasitoids Cotesia sesamiae (Cameron) (Hymenoptera: Braconidae) and its exotic congener Cotesia flavipes Cameron (Hymenoptera: Braconidae) emerging from three species of field-collected stemborers were compared. There were no significant differences in numbers of progeny of the two parasitoids from the African stemborers, Chilo orichalcociliellus (Strand) (Lepidoptera: Pyralidae) and Sesamia calamistis Hampson (Lepidoptera: Noctuidae). Cotesia flavipes produced more progeny than C. sesamiae on large larvae of its coevolved Asian host, Chilo partellus (Swinhoe). No significant differences in the number of parasitoid progeny were observed for different-sized Ch. orichakocilidltis or S. calamistis larvae. These data suggest …

Host Location And Acceptance By Cotesia Flavipes Cameron And C. Sesamiae (Cameron) (Hymenoptera: Braconidae), Parasitoids Of African Gramineous Stemborers: Role Of Frass And Other Host Cues, Adele J. Ngi-Song, William A. Overholt

All Peer-Reviewed Publications

Naive females of Cotesia flavipes Cameron and Cotesia sesamiae (Cameron) were attracted, in a T-tube olfactometer, to volatile kairomones from frass produced by Chilo partellus (Swinhoe), Chilo orichalcociliellus Strand, Sesamia calamistis Hampson, and Busseola fusca (Fuller) fed on maize (Zea mays L.), sorghum [Sorghum bicolor (L.)], and napier grass (Pen. nisetum purpureum Schumach). In dual-choice tests, C. flavipes and C. sesamiae were generally unable to discriminate between volatiles from frass produced by any of the four different stemborer species fed on maize stalk. When larvae of C. partellus and S. calamistis were washed in distilled water, their acceptance by both …

Neem Seed Extract Spray Applications As Low-Cost Inputs For Management Of The Flower Thrips In The Cowpea Crop, R. C. Saxena, E. L. Kidiavai

All Peer-Reviewed Publications

In field trials conducted at the Experiment Station and in a farmer's field at Mbita near the shores of Lake Victoria, Kenya, applications of 2% or 3% neem seed extract (NSE) @ 200 l/ha with a knapsack sprayer at 38, 47 and 51 days after emergence (DE) of the cowpea crop or 5%, 10% or 20% NSE sprayed @ 10 l/ha with an ultra-low-volume applicator at 31, 39 and 49 DE often significantly reduced the number of larvae of the flower thrips, Megalurothrips sjostedti (Trybom), in cowpea flowers recorded 2 days after each treatment. Also fewer adults occurred in flowers …

Changes Over Twelve Years In Populations Of Glossina Pallidipes And Glossina Longipennis (Diptera: Glossinidae) Subject To Varying Trapping Pressure At Nguruman, South-West Kenya, R. Brightwell, R. D. Dransfield, P. Stevenson, B. Williams

All Peer-Reviewed Publications

Long term changes in the size of populations of the tsetse Glossina pallidipes Austen and G. longipennis Corti Were monitored over a 12 year period at Nguruman in south-western Kenya. Tsetse populations were subject to droughts of varying intensity and, from 1987, to trapping, initially by a research organization, and later by a community-based development project. Populations were mainly sampled using odour-baited biconical traps, with data from other monitoring traps corrected accordingly. Mark-release-recapture studies were carried out to relate trap catches to absolute population size, and to quantify movement between subpopulations. Trypanosomiasis incidence rates in a herd of local cattle …

The Impact Of Ixodiphagus Hookeri, A Tick Parasitoid, On Amblyomma Variegatum (Acari: Ixodidae) In A Field Trial In Kenya, E. N. Mwangi, S. M. Hassan, G. P. Kaaya, S. Essuman

All Peer-Reviewed Publications

In an experiment to investigate the effect of the tick parasitoid, Ixodiphagus hookeri, on tick numbers on cattle, 150 000 parasitoids were released over a period of 1 year in a field where ten cattle infested with multiple tick species were kept. Amblyomma variegatum was reduced from 44 to two ticks per animal while Rhipicephalus appendiculatus increased over the time of parasitoid release. During the time of release 51% of the nymphs of A. variegatum collected from the animals were parasitized. The recovery of the parasitoids after the releases were stopped was only 9%. The total numbers of A. variegatum …

Haemolymph Pigment Composition As A Chemometric Indicator Of Phase In The Desert Locust, Schistocerca Gregaria, Hassane Mahamat, Ahmed Hassanali, David Munyinyi

All Peer-Reviewed Publications

The blue biliverdin pigment in the haemolymph of Schisfocerca gregria Forskâl(Orthoptera: Acrididae) was shown to be associated with all the stages and ages of the solitary-reared (solitarious) insects, irrespective of their origin or diet. The pigment was absent or present in very small quantities in the crowd-reared (gregarious) insects. The ratio of absorbance at 460 run and 680 run, the former representing the A,max for the carotenoid pigment and the latter for the biliverdin, provides a clearcut index for partitioning the phases. The mean value of the index for the gregarious group fell in the range 3.69 to 4.78. That …

Utilisation Of Wild Gramineous Plants For Management Of Cereal Stemborers In Africa, Z. R. Khan, P. Chiliswa, K. Ampong-Nyarko, L. E. Smart, A. Polaszek, J. Wandera, M. A. Mulaa

All Peer-Reviewed Publications

Field trials in Kenya demonstrated that the forage grass, Sorghum vulgäre sudanense (Sudan grass) attracted greater oviposition by stemborers than cultivated maize, resulting in significant increase in maize yield. On the other hand, the non-host forage plant, Melinis minutiflora (molasses grass), when inter-cropped with maize, repelled gravid stemborer females from ovipositing on maize, resulting in significant reduction in stemborer infestation. Using these trap- and repellent gramineous plants, a novel pest management approach based on a 'push-pull' or stimulo-deterrent diversionary strategy is being developed where stemborers are repelled from the food crop and are simultaneously attracted to a discard or trap …

Geographic Variation In Host Selection Behaviour And Reproductive Success In The Stemborer Parasitoid Cotesia Flavipes (Hymenoptera: Braconidae), R. P.J. Potting, L. E.M. Vet, W. A. Overholt

All Peer-Reviewed Publications

Local parasitoid populations may be adapted to their sympatric major plant host complex. Parasitoid strains may thus differ in their propensity to search for a particular micro-habitat or host or they may differ in their physiological compatibility with particular plant or host species. Cotesiaflavipes Cameron, a larval parasitoid used worldwide in biological control against tropical stemborers, has a wide host range in diverse habitats. The existence of plant and/or host specific strains in C. flavipes has been postulated. To provide insight into the existence of strains in C. flavipes, we compared the plant/host complex selection behaviour, and physiological compatibility with …

Sensitivities Of Report Writing For Weak-Rock Projects, Allen W. Hatheway

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Weak rock is the natural realm of geological engineers and engineering geologists. We are the best equipped geotechnical professionals to deal effectively with these difficult and generally complex earth materials, and we have the obligation to produce the most informative technical reports possible in weak-rock assignments. Because of the strength-related problems of weak rock, we should remain cognizant of the need to emphasize several aspects of our reports. For this purpose weak rock occurs because of one or more strength-degrading considerations: 1. Weak to deleterious lithology; the latter imparting damaging characteristics to concretes and to rock utilized as rip-rap and …

Evaluation Of Unified Interaction Parameter Model Parameters For Calculating Activities Of Ferromanganese Alloys: Mn-Fe-C, Mn-Fe-Si, Mn-C-Si, And Mn-Fe-C-Si Systems, L. I. Hongjie, Arthur E. Morris

Materials Science and Engineering Faculty Research & Creative Works

Interaction parameters for Mn-based alloys were evaluated using both carbon solubility and activity data for species in binary and ternary manganese alloys. The parameters at 1400 °C are the following εcc = -4.5; εccc = 58.8; εFeCC = 1.5; εFeCC = 2.5; In γC0 = -1.15 . εsisi = 15.5; εsisisi = 2.69; εFeSi = 2.5; εcsi = 12.4; εccsi = 27.5; In γSi0 = -7.46 The unified interaction parameter model (UIPM) was used to calculate the activity coefficients of species and the solubility of carbon in ferromanganese alloys (up to quaternary Mn-Fe-C-Si). The results were in good agreement with …

Diamond For Fiber-Optic Raman Spectroscopy, Jianli Zheng

Electrical & Computer Engineering Theses & Dissertations

Raman spectroscopy is a powerful technique for molecular structural studies and concentration measurement. Being a single beam technique, the Raman intensity depends on the optical power of the excitation source, optical alignment of the system, detector response as well as species concentration. To eliminate the unwanted variations in the system and get the concentration information of the species, intensity referencing is necessary. The existing referencing methods either use a constant Raman band of the sample, or add a chemically inert material with known concentration into the sample. Unfortunately, the former method is not always applicable and the latter is not …

Choline Acetyltransferase And Carnitine Acetyltransferase Activity In Human Spermatozoa During Capacitation, Lisa A. Eccles

Theses and Dissertations in Biomedical Sciences

The regional distribution of ChAT activity in human spermatozoa is altered during in vitro capacitation and it correlates with the fertilizing potential of sperm.

Regional immunoreactivity in human spermatozoa as assessed by fluorescent immunocytochemistry was compared with ChAT and CaAT activity determined by enzymatic methodologies. Increasing proportions of sperm exhibited ChAT immunoreactivity along the equatorial region with a concomitant decrease in ChAT reactivity in the midpiece. Also, competitive studies with unlabeled ChAT blocked the equatorial region labeling; the unlabeled CaAT blocked staining along the midpiece region of the tail, suggesting some cross-reactivity of the ChAT antiserum with the CaAT enzyme. …

Explaining The Pattern Of Secured Credit, Ronald J. Mann

Faculty Scholarship

Granting collateral to secure loans is a prominent feature of the U.S. economy, but, surprisingly, we do not understand how borrowers and lenders decide whether to engage in a secured or an unsecured transaction. In this Article, Professor Mann argues that existing theories of secured lending are inadequate because the theories' predictions have not been tested against empirical data. To understand the actual pattern of secured credit, Professor Mann interviewed more than twenty borrowers and lenders in various sectors of the economy. Based on the evidence gathered in these interviews, as well as on preexisting empirical studies, this Article develops …

Homosexuals, Torts, And Dangerous Things, Katherine M. Franke

Faculty Scholarship

Negligent, intentional, and strict liability torts. From a canonical standpoint, whatever else one might teach, it is not a first-year torts course if these three concepts are not covered. Torts has a canon, even a Restatement. Yet a canon evolves only after some criteria of value has been established such that privileged texts can be identified according to some authoritative standard. In other words, a canon is the result of a process by which a rule of recognition identifies authoritative texts.

At what point can we say that torts became a field and an intact legal subject, the canon …

The Rise Of Sublocal Structures In Urban Governance, Richard Briffault

Faculty Scholarship

The dominant law and economics model of local government, based on the work of Charles M. Tiebout, assumes that decentralization of power to local governments promotes the efficient delivery of public goods and services. In his seminal article, A Pure Theory of Local Expenditures, Tiebout contended that the existence of a large number of local governments in any given area permits a "market solution" to the question of how to determine the level and mix of government services that people desire. The multiplicity of local governments in an area means that, as long as each locality is free to …

Extraterritoriality And Multiterritorality In Copyright Infringement, Jane C. Ginsburg

Faculty Scholarship

Extraterritorial application of U.S. law, as Professor Curtis Bradley demonstrates, is highly suspect, if not illegitimate, unless clearly authorized by Congress. The apparently “extraterritorial” character of much recent copyright litigation has led some U.S. courts to dismiss for lack of subject matter jurisdiction or on grounds of forum non conveniens when the cases present offshore points of attachment. As copyright commerce becomes increasingly international, some of these dismissals may be unwarranted. They also may be incorrect in their refusal to apply U.S. law or retain U.S. jurisdiction over the parties: the decisions may be too quick to perceive "extra"-territoriality in …

Asteroids And Comets: U.S. And International Law And The Lowest-Probability, Highest Consequence Risk, Michael B. Gerrard, Anna W. Barber

Faculty Scholarship

Asteroids and comets pose unique policy problems. They are the ultimate example of a low probability, high consequence event: no one in recorded human history is confirmed to have ever died from an asteroid or a comet, but the odds are that at some time in the next several centuries (and conceivably next year) an asteroid or a comet will cause mass localized destruction and that at some time in the coming half million years (and conceivably next year), an asteroid or a comet will kill several billion people. The sudden extinction of the dinosaurs, and most other species 65 …

Crime, Community Penalty And Integration With Legal Formalism In The South Pacific, Mark Findlay

Research Collection Yong Pung How School Of Law

The influence of introduced legality on prevailing culture, and vice versa, are common concerns for analysis when considering the existence and development of customary law. Much of the limited writing on law and custom prefers to speculate on the impact of introduced law on already present modes of regulation. While recognising these structuralist contexts of influence, often oversimplified as they are represented, this paper prefers to explore the adaptation of legal formalism in contexts of resilient and resonant custom.Further, the paper examines instances where despite the fact that custom has modified institutional legality, the latter claims predominance over culture or …

Comment On 'Profits Derived From Breach Of Contract Or Restitution', Howard Hunter

Research Collection Yong Pung How School Of Law

There is little with which to disagree in Professor Waddams' paper on the categorisation of damage recoveries in the cases posited, viz, those involving a breach which results in benefit to the breaching party but no loss of any consequence to the nonbreaching party. If the goal of contract remedies is to compensate the plaintiff for loss, then, presumably, there should be no recovery at all in such cases. At most there might be nominal damages to compensate for some transaction costs or perhaps as a ’declaration of rights’. In some of the cases considered by Waddams, breach might be …

A Small-Angle Neutron Scattering Study Of Γ-Crystallins Near Their Isoelectric Point, Paul Petitt, Michael Eugene Edwards, Daniel Forciniti

Chemical and Biochemical Engineering Faculty Research & Creative Works

In this paper, a small-angle neutron scattering study of γII-crystallins near their isoelectric point is presented. The experiments were carried out using protein concentrations of 5.7-85.7 mg/ml at temperatures in the range 11-60°C. The experimental data were analyzed using an ellipsoidal model for intraparticle correlations and the mean spherical approximation for interparticle correlations. Our studies revealed that γII-crystallins have a thick hydration layer, which is possibly due to the special arrangement of polar and ionic groups on their surface. The temperature scan shows that, as a result of relatively strong attractive forces, clusters of two, three, or higher oligomers are …

Varietal Differences In The Total And Enantiomeric Composition Of Theanine In Tea, K. Helen Ekborg-Ott, Andre Taylor, Daniel W. Armstrong

Chemistry Faculty Research & Creative Works

Theanine is the main amino acid component in tea. It usually constitutes between 1 and 2% of the dry weight of the tea leaves. It is as prevalent in tea as all other free amino acids combined. Both enantiomers of theanine were found to have a similar sweet taste, with little or no aftertaste. It was found that black and half-green teas (except for Formosa Oolong) contained as much, or more, theanine as green teas. No correlation was found between the absolute concentration of theanine in tea and its enantiomeric composition. An inverse correlation was found between certain grades of …

Integrated Queries To Existing Bibliographic And Structured Databases, Ee Peng Lim, Ying Lu

Research Collection School Of Computing and Information Systems

It is widely accepted that future digital library applications have to be built upon different kinds of database servers to draw upon different forms of data, including bibliographic, text, multimedia, and structured data. In this paper, the problem of integrating existing public bibliographic databases and structured databases which reside at different locations in the network is addressed. Although bibliographic data is semistructured, its attribute set is often determined by an international standard known as MARC. To unify bibliographic and structured data, the well-known SQL was extended to model bibliographic related attributes and queries. In particular, a new data type was …
