R&D, Patenting and Growth: The Role of Public Policy

This paper uses panel regression techniques to assess the policy determinants of private sector innovative activity – proxied by R&D expenditure and the number of new patents – across 19 OECD countries. The relationship between innovation indicators and multifactor productivity (MFP) growth is also examined with a particular focus on the role of public policies in influencing the returns to new knowledge. The results establish an empirical link between R&D and patenting, as well as between these measures of innovation intensity and MFP growth. Innovation-specific policies such as R&D tax incentives, direct government support and patent rights are found to be successful in encouraging the innovative activities associated with higher productivity growth. However, direct empirical evidence of the positive effects of these policies on productivity is less forthcoming. A pervasive theme from the analysis is the importance of coupling policies aimed at encouraging innovation or technological adoption with well designed framework policies that allow knowledge spillovers to proliferate. In particular, the settings of framework policies relating to product market regulation, openness to trade and debtor protection in bankruptcy provisions are found to be important for the diffusion of new technologies. R&D, brevets et croissance : le role des politiques publiques Ce document utilise des techniques de regression en panel pour evaluer les determinants politiques de l'activite d'innovation du secteur prive – representee par les depenses de R & D et le nombre de brevet - a travers 19 pays de l'OCDE. La relation entre les indicateurs de l'innovation et la croissance de la productivite multifactorielle (PMF) est egalement analysee avec une attention particuliere sur le role des politiques publiques pour influencer les rendements de nouvelles connaissances. Les resultats etablissent un lien empirique entre la R & D et les brevets, ainsi qu'entre ces mesures de l'intensite de l'innovation et la croissance de la PMF. Des politiques specifiques d'innovation telles que des incitations fiscales pour la R & D, le soutien direct de l'Etat et les droits de brevet sont averees efficaces pour encourager les activites innovantes associees a une plus forte croissance de la productivite. Toutefois, les preuves empiriques directes des effets positifs de ces politiques sur la productivite sont plus rares. Un theme recurrent de l'analyse est l'importance du couplage des politiques visant a encourager l'innovation ou l'adoption technologique avec des politiques-cadres bien concues qui permettent une plus large diffusion des connaissances. En particulier, les parametres des politiques-cadres relatives a la reglementation des marches de produits, l'ouverture au commerce et a la protection du debiteur dans les dispositions de la faillite sont juges importants pour la diffusion des nouvelles technologies.
Long term follow-up of lenticular autofluorescence and transmittance in healthy volunteers.

This study was undertaken to assess long term changes in the lenticular autofluorescence and transmittance of healthy volunteers. Both eyes of 15 healthy volunteers aged 8 to 62 years were examined by slit-lamp examination and fluorophotometric measurements of lenticular autofluorescence (lambdaexc=415 nm-490 nm, lambdaem= 510 nm-550 nm) and transmittance (lambda=415 nm-550 nm) in 1983 and 1996. The changes in lenticular autofluorescence and transmittance between 1983 and 1996 were determined and compared with those calculated on the basis of age-dependence curves of a group of 56 healthy volunteers measured in 1983. These curves were obtained by approximation of the values of the 56 healthy volunteers by a linear, polynomial or exponential function of age, respectively. A mean yearly increase of lenticular autofluorescence of 8.69 ng . equivalent fluorescein . ml-1 . year-1 was observed in the 15 volunteers between 1983 and 1996 and this increase was significantly larger than that calculated on the basis of the three age-dependence curves in 1983 (6.36, 6.47 and 6.53 ng . equivalent fluorescein . ml-1 . year-1, P=0.0026, 0.0037 and 0.0044, respectively). The transmittance showed a mean yearly decrease of 0.508% . year-1 which was significantly larger than calculated on the basis of the three age-dependence curves in 1983 (0.153, 0.220 and 0.183% . year-1, P=0. 0033, 0.012 and 0.0059, respectively). One volunteer, i.e. the individual with the highest lenticular autofluorescence and lowest transmittance in 1983, had developed cataract in 1996. These measurements demonstrate for the first time, quantitative changes in lenticular autofluorescence and transmittance in a long term follow up. The at least 35% larger increase of autofluorescence and 130% larger decrease in transmittance in the follow-up group between 1983 and 1996 in comparison with the values based on age-dependent curves in 1983 could be caused by the increased solar UV radiation in The Netherlands during that period of time.

Fast Retrospectively Gated Quantitative Four-Dimensional (4D) Cardiac Micro Computed Tomography Imaging of Free-Breathing Mice

Objective:We sought to demonstrate retrospectively gated dynamic 3D cardiac micro computed tomography (CT) of free-breathing mice. Materials and Methods:Five C57Bl6 mice were scanned using a cone-beam scanner with a slip-ring-mounted flat-panel detector. After the injection of an intravascular iodinated contrast agent, projection images were acquired over the course of 50 seconds, while the scanner rotated through 10 complete rotations. The mouse respiratory and electrocardiogram signals were recorder simultaneously with image acquisition. After acquisition, the projection images were retrospectively sorted into projections belonging to different cardiac time points, occurring only during expiration. Results:Dynamic 3D cardiac images, with isotropic 150-&mgr;m voxel spacing, were reconstructed at 12-millisecond intervals throughout the cardiac cycle in all mice. The average ejection fraction and cardiac output were 58.2 ± 4.6% and 11.4 ± 1.3 mL/min, respectively. The measured entrance dose for the entire scan was 28 cGy. Repeat scans of the same animals showed that intrasubject variability was smaller than intersubject variability. Conclusions:We have developed a high-resolution micro computed tomography method for evaluating the cardiac function and morphology of free-breathing mice in acquisition times shorter than 1 minute.
Season influences FSH concentration in ovariectomized Ile-de-France ewes.

Ile-de-France ewes were ovariectomized during anoestrus or the mid-luteal phase of an oestrous cycle (day of ovariectomy = Day 0). In a short-term study, FSH concentrations were measured in blood samples collected hourly the day before and on Days 1, 3, 7 and 15 after ovariectomy (10 ewes per group). FSH concentrations increased significantly from 6.1 to 16.5 ng/ml within 1 day of ovariectomy and increased further to 47.1 ng/ml by Day 15. Differences between seasons of ovariectomy were not significant. In a long-term study, FSH concentrations were measured in blood samples collected hourly on Days 7, 15, 30, 60, 90, 120, 150 and 180 after ovariectomy in anoestrus or the breeding season (10 ewes per group). Further samples were taken (5 ewes/group) at 240 and 365 days after ovariectomy. The pattern of change in FSH after ovariectomy differed between the two seasons and the interaction between season and sampling day was significant. For ewes ovariectomized during anoestrus, FSH concentrations increased to a maximum by Day 180 and remained high thereafter. In contrast FSH increased more slowly in ewes ovariectomized in the breeding season and differences between the groups were significant from Day 90 to Day 270. However, both groups had similar FSH concentrations at Day 365. These results show that FSH concentrations increase rapidly after ovariectomy. There are seasonal differences in FSH concentrations in the absence of ovarian feedback with increases in FSH concentration around the time of the onset of the breeding season. Once FSH concentrations had reached a maximum, major seasonal changes were no longer apparent. (ABSTRACT TRUNCATED AT 250 WORDS)
Amygdalar Gating of Early Sensory Processing through Interactions with Locus Coeruleus

Fear- and stress-induced activity in the amygdala has been hypothesized to influence sensory brain regions through the influence of the amygdala on neuromodulatory centers. To directly examine this relationship, we used optical imaging to observe odor-evoked activity in populations of olfactory bulb inhibitory interneurons and of synaptic terminals of olfactory sensory neurons (the primary sensory neurons of the olfactory system, which provide the initial olfactory input to the brain) during pharmacological inactivation of amygdala and locus coeruleus (LC) in mice. Although the amygdala does not directly project to the olfactory bulb, joint pharmacological inactivation of the central, basolateral, and lateral nuclei of the amygdala nonetheless strongly suppressed odor-evoked activity in GABAergic inhibitory interneuron populations in the OB. This suppression was prevented by inactivation of LC or pretreatment of the olfactory bulb with a broad-spectrum noradrenergic receptor antagonist. Visualization of synaptic output from olfactory sensory neuron terminals into the olfactory bulb of the brain revealed that amygdalar inactivation preferentially strengthened the odor-evoked synaptic output of weakly activated populations of sensory afferents from the nose, thus demonstrating a change in sensory gating potentially mediated by local inhibition of olfactory sensory neuron terminals. We conclude that amygdalar activity influences olfactory processing as early as the primary sensory input to the brain by modulating norepinephrine release from the locus coeruleus into the olfactory bulb. These findings show that the amygdala and LC state actively determines which sensory signals are selected for processing in sensory brain regions. Similar local circuitry operates in the olfactory, visual, and auditory systems, suggesting a potentially shared mechanism across modalities. SIGNIFICANCE STATEMENT The affective state is increasingly understood to influence early neural processing of sensory stimuli, not just the behavioral response to those stimuli. The present study elucidates one circuit by which the amygdala, a critical structure for emotional learning, valence coding, and stress, can shape sensory input to the brain and early sensory processing through its connections to the locus coeruleus. One function of this interaction appears to be sensory gating, because inactivating the central, basolateral, and lateral nuclei of the amygdala selectively strengthened the weakest olfactory inputs to the brain. This linkage of amygdalar and LC output to primary sensory signaling may have implications for affective disorders that include sensory dysfunctions like hypervigilance, attentional bias, and impaired sensory gating.
Vulnerabilities and resilience of European power generation to 1.5 °C, 2 °C and 3 °C warming

The electricity sector is currently considered mainly on the emission side of the climate change equation. In order to limit climate warming to below 2 °C, or even 1.5 °C, it must undergo a rapid transition towards carbon neutral production by the mid-century. Simultaneously, electricity generating technologies will be vulnerable to climate change. Here, we assess the impacts of climate change on wind, solar photovoltaic, hydro and thermoelectric power generation in Europe using a consistent modelling approach across the different technologies. We compare the impacts for different global warming scenarios: +1.5 °C, +2 °C and +3 °C. Results show that climate change has negative impacts on electricity production in most countries and for most technologies. Such impacts remain limited for a 1.5 °C warming, and roughly double for a 3 °C warming. Impacts are relatively limited for solar photovoltaic and wind power potential which may reduce up to 10%, while hydropower and thermoelectric generation may decrease by up to 20%. Generally, impacts are more severe in southern Europe than in northern Europe, inducing inequity between EU countries. We show that a higher share of renewables could reduce the vulnerability of power generation to climate change, although the variability of wind and solar PV production remains a significant challenge.
The Secret to Getting Ahead Is Getting Started: Early Impacts of a Rural Development Project

Interventions in rural development projects vary in their likely time to impact. Some offer rapid payoffs after minimal learning and investment, while others offer larger payoffs but entail delays and may require learning or significant investment of labor and capital. Short-term impacts included reductions in stored grain losses due to improved silos and increase in household savings due to increased participation in savings groups. The least poor are most likely to invest labor and capital in slow-to-accrue payoffs like soil erosion abatement from building conservation structures. Our results suggest that targeting project interventions by asset level can enhance impacts.
Epithelial cells of the epididymis show regional variations with respect to the secretion or endocytosis of immobilin as revealed by light and electron microscope immunocytochemistry

The localization of immobilin, a glycoprotein known to be present and to immobilize spermatozoa in the lumen of the epididymis, was investigated using light and electron microscope immunocytochemistry. In the light microscope, a distinct immunoperoxidase reaction product was observed in the lumen over the brush border of the epithelial nonciliated cells of the efferent ducts, while only a faint reaction was seen over their supranuclear region. In the proximal area of the initial segment of the epididymis no immunoperoxidase staining was observed either over epithelial cells or in the lumen. In the middle area of the initial segment, several epithelial principal cells became intensely immunostained but the majority were unstained; a weak reaction appeared in the lumen. In the distal area of the initial segment, more principal cells became immunostained, and while some were intensely reactive, others were moderately or weakly stained or unreactive. In the intermediate zone and proximal caput epididymidis, the principal cells showed the maximal immunoreactivity with all principal cells being reactive; staining in the lumen also reached its maximal reactivity in these areas. Immunostaining of principal cells gradually decreased along the epididymal duct and disappeared in the cauda epididymidis, however, an intense reaction persisted in the lumen. In the distal area of the cauda epididymidis, clear cells were reactive. In the electron microscope, immunogold labeling of reactive principal cells of the middle and distal areas of the initial segment, intermediate zone, and caput epididymidis was detected over cisternae of endoplasmic reticulum, stacks of Golgi saccules, and spherical electron lucent (200–400 nm in diameter) vesicles. The latter were present on the trans face of the Golgi stack, in the vicinity of the Golgi apparatus, and close to the apical cell surface; they are considered as secretory vesicles involved in the secretion of immobilin. In the distal area of the cauda epididymidis, epithelial clear cells showed an intense immunogold labeling over their endocytic apparatus. Immunogold labeling in the lumen of the epididymis was found over a fine flocculent material dispersed between the sperm. This material was especially abundant in the cauda epididymidis and did not appear to be bound to the surface of the sperm. The present results suggest that principal cells of the epididymis are involved in the secretion of immobilin, but that a differential secretory pattern exists between epididymal segments with maximal secretory activity occurring in the intermediate zone and proximal caput epididymidis, while no secretion takes place in the cauda epididymidis. Excess immobilin appears to be endocytosed for degradation by clear cells of the cauda epididymidis.
Sugar-sweetened beverage intake, chromosome 9p21 variants, and risk of myocardial infarction in Hispanics.

BACKGROUND Chromosome 9p21 variants are among the most robust genetic markers for coronary artery disease (CAD), and previous studies have suggested that genetic effects of this locus might be modified by dietary factors. Intake of sugar-sweetened beverages (SSBs), which are the main dietary source of added sugar, has been shown to interact with genetic factors in affecting CAD risk factors such as obesity. OBJECTIVE We aimed to test whether SSB intake modified the association between chromosome 9p21 variants and CAD risk in Hispanics living in Costa Rica. DESIGN The current study included 1560 incident cases of nonfatal myocardial infarction (MI) and 1751 population-based controls. Three independent single nucleotide polymorphisms (SNPs) at the chromosome 9p21 locus were genotyped. SSB intake was assessed with the use of a food-frequency questionnaire and was defined as the frequency of intake of daily servings of sweetened beverages and fruit juice. RESULTS We showed a significant interaction between SSB intake and one of the 3 variants (i.e., rs4977574) on MI risk. The per–risk allele OR (95% CI) of rs4977574 for MI was 1.44 (1.19, 1.74) in participants with higher SSB consumption (>2 servings/d), 1.21 (1.00, 1.47) in those with average consumption (1–2 servings/d), and 0.97 (0.81, 1.16) in subjects with lower consumption (<1 serving/d; P-interaction = 0.005). A genetic risk score derived from the sum of risk alleles of the 3 SNPs also showed a significant interaction with SSB intake on MI risk (P-interaction = 0.03). CONCLUSION Our data suggest that unhealthy dietary habits such as higher intake of SSBs could exacerbate the effects of chromosome 9p21 variants on CAD.
Developing Graduate Students of Color for the Professoriate in Science, Technology, Engineering, and Mathematics (STEM) - eScholarship

This paper presents part of the results of a completed study entitled A Longitudinal Study of Minority Ph.D.s from 1980-1990: Progress and Outcomes in Science and Engineering at the University of California during Graduate School and Professional Life. It focuses particularly on the graduate school experience and degree of preparation for the professoriate of African American doctoral students in the sciences and engineering, and presents the results of a survey of 33 African American STEM Ph.D.s from the University of California earned between 1980-1990. Relationships with thesis advisors and principal investigators are evaluated by the study participants in fifteen specific areas from highly-ranked intellectual development to low-ranked training in grant writing. Deficits in training and socialization are discussed along with the tension between being both an African American and a graduate student. Career choices and outcomes are presented. These findings, in conjunction with current analyses of graduate education in STEM, suggest ways in which graduate training for all could be improved.
Effects of Surfactants on the Photosensitized Production of Tyrosine Radicals Studied by Photo‐CIDNP ¶

The influence of the surfactants sodium dodecyl sulphate, cetyltrimethyl‐ammonium bromide and triton X‐100 on the photochemically induced dynamic nuclear polarization (CIDNP) of N‐acetyl tyrosine has been investigated. Three photosensitizers were used to generate polarization: thionin, eosin Y and flavin mononucleotide. 600 MHz 1H photo‐CIDNP experiments, supported by laser flash photolysis transient absorption measurements, indicate that the neutral triton surfactant has no influence on the nuclear polarization, but that the other two, charged, amphiphiles affect the photochemistry in a variety of ways, depending on the surfactant concentration and the identity of the sensitizer.
Maribacter confluentis sp. nov., isolated from the junction between the ocean and a freshwater spring.

A Gram-stain-negative, aerobic, non-spore-forming, non-flagellated, non-gliding and rod-shaped bacterial strain, SSK2-2(T), was isolated from the place where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK2-2(T) grew optimally at 30 °C, at pH 7.0-8.0 and in the presence of 2.0-3.0% (w/v) NaCl. The neighbour-joining phylogenetic tree based on 16S rRNA gene sequences revealed that strain SSK2-2(T) fell within the clade comprising the type strains of species of the genus Maribacter, joining the type strain of Maribacter sedimenticola with which it shared 99.4% similarity. Sequence similarities to the type strains of other Maribacter species were 94.6-98.2%. Strain SSK2-2(T) contained MK-6 as the predominant menaquinone and iso-C17 : 0 3-OH, iso-C15 : 0, iso-C15 : 1 G, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or 10-methyl C16 : 0) as the major fatty acids. The major polar lipids of strain SSK2-2(T) were phosphatidylethanolamine and one unidentified lipid. The DNA G+C content of strain SSK2-2(T) was 38.2 mol% and mean levels of DNA-DNA relatedness with the type strains of four phylogenetically related species of the genus Maribacter were 11-24%. Differential phenotypic properties, together with phylogenetic and genetic distinctiveness, revealed that strain SSK2-2(T) is separate from other Maribacter species. On the basis of the data presented, strain SSK2-2(T) is considered to represent a novel species of the genus Maribacter, for which the name Maribacter confluentis sp. nov. is proposed. The type strain is SSK2-2(T) ( = KCTC 42604(T) = CECT 8869(T)).
Ultrastructure and synaptology of the paratrigeminal nucleus in the rat: Primary pharyngeal and laryngeal afferent projections

The paratrigeminal nucleus (PTN) receives primary afferent projections from the aerodigestive tract and orofacial regions and plays a role in the integration of visceral and somatic information. This study describes the fine structure of the rat PTN and the synaptology of primary afferent projections from the pharynx and larynx. Injections of wheat germ agglutinin‐horseradish peroxidase (WGA‐HRP) or cholera toxin‐HRP (CT‐HRP) were made into the wall of the pharynx or larynx to label primary afferent axon terminals. Light microscopic observations demonstrated that afferent axons terminated bilaterally in overlapping fields in the PTN. Electron microscopic observations of the PTN revealed that there were three distinct classes of neurons, based on morphology and axosomatic contacts. The most abundant neurons, Type 1, were fusiform in shape and received very few or no axosomatic contacts. Type 2 neurons contained prominent Nissl substance (rough endoplasmic reticulum) and few axosomatic contacts, while Type 3 neurons had many axosomatic synapses. Terminals containing round, clear vesicles and forming asymmetric contacts (round asymmetric, RA) with dendrites were the predominant synaptic type in the PTN. Primary afferent terminals from the pharynx and larynx were of the RA type and formed synaptic contacts with small‐diameter (<1 μm) dendrites. Visceral primary afferent inputs from the pharynx and larynx overlap with trigeminal somatic afferents in the PTN and have similar synaptic morphology. The results support the concept that the PTN provides an anatomical substrate for mediating viscerovisceral and somatovisceral reflexes via efferent connections with autonomic centers in the brainstem.
