Surfactants

description: The Critical Micelle Concentration (CMC) is the surfactant concentration above which the addition of a monomer leads to the formation of the first micelle. Above the CMC, monomers and micelles exist in dynamic equilibrium. Almost all physical properties of a surfactant solution exhibit a sharp concentration dependent discontinuity in the region of micellization. Below the CMC, the thermodynamic properties of surfactant solutions (osmotic pressure, conductivity, etc) follow ideal or regular laws of same type as those of solutions which contain a large molecular solute. Above the CMC, one can observe a clearly non-ideal behavior and a practically constant activity. The CMC of a surfactant is defined as the value at which the solution property of the molecule shows an abrupt change. The methods for measuring CMC can be classified into two types. The first are methods which detect abrupt changes in the monomolecular concentration, such as the surface tension and electric conductivity methods. The second type detects micelles and includes the dye adsorption method and the solubilization method.

Multimeric Complexes

description: Mitochondrial fission is important for various cellular processes such as mitochondrial morphology maintenance, proper distribution of mitochondria to energy demanding regions of the cell and regulation of cell death. In yeast, mitochondrial fission requires Dnm1p, a dynamin related GTPase, Mdv1p, a soluble protein with coiled-coil and WD-repeat motifs and Fis1p, a tail-anchored integral membrane protein containing a tetratricopeptide repeat-like fold. Caf4p, a homolog of Mdv1p was recently identified as a component of the fission pathway based on its ability to interact with the other fission proteins. However, Caf4p is not strictly required for mitochondrial fission suggesting that it has a more regulatory function. Studies in yeast indicate that mitochondrial fission consists of two distinct steps: an early step during which Dnm1p and Mdv1p assemble into discrete complexes at distinct sites on the outer mitochondrial membrane. In vivo characterization of an assembly deficient Dnm1G385Dp mutant protein suggests that smaller oligomers of Dnm1p are recruited to pre-existing Fis1p-Mdv1p complexes on mitochondria where they further assemble to form multimeric complexes. This Dnm1p multimerization drives the reorganization of Mdv1p from a uniform mitochondrial distribution to punctate fission complexes that also contain Fis1p. In a later step, these fission complexes are activated, leading to division of the mitochondrial compartment. Both Mdv1p and Fis1p have been proposed to play additional roles in the postassembly activation of mitochondrial fission although the nature of these events is currently 3 unclear.

Venezuela: Endrödi 1966a: 185; Moore et al. 2018b: 170. Other: Schönherr 1817: 189 (America - as Melolontha unciata); Arrow 1937b: 10 (Colombia); Blackwelder 1944: 251 (Colombia); Endrödi 1966a: 185 (Bolivia, Colombia - designation LECTOTYPE Melolontha discolor, Costa Rica, Ecuador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Peru, Trinidad and Tobago), 1985a: 57, 134 (Bolivia–Mexico, Antilles); Ratcliffe 2003: 118 (Argentina–Mexico); Ponchel 2011 (not mentioned); Dupuis 2016b (not mentioned); Moore et al. 2018b: 170 (Argentina, Belize, Bolivia, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, Trinidad and Tobago).
Note 1. According to Ratcliffe and Cave (2015: 290), the record of Cyclocephala discolor from Haiti in Endrödi (1966a: 185, 1985a: 57) is incorrect, as this is a Central and South American species.
Note 2. Cyclocephala discolor is described from Guyana by Herbst (1790: 73), but to our knowledge has not since been reported from that country. The only instances it is mentioned for Suriname and French Guiana are in Endrödi (1966a: 185) and Moore et al. (2018b: 170), the latter of whom merely repeats the former. Duranton (2011: 12) considers its occurrence in French Guiana as dubious and the species is not mentioned in the checklists of Ponchel (2011) and Dupuis (2016b). We have not seen specimens from Suriname. The literature indicates that this species can be found throughout Central America and in the western half of South America. We regard its occurrence in the research area as doubtful and in need of confirmation.

Structural basis for complex visual receptive fields: a study of the turtle inner retina
Creators: name: Guiloff, Gloria S.
Publisher: name: University of Utah
Year: 2012
Subjects: subject: Physiology
subject: FOS: Biological sciences

description: Visual cells respond to stimuli placed in restricted regions of visual space called their visual receptive fields. Visual output to the brain, relayed by retinal ganglion cell axons, results from neural processing within the retinal layers. The turtle retina is used here as a model to study the structural basis underlying ganglion cell complex receptive fields. The specific aims are: (1) to identify and quantify the synaptic content of the inner plexiform layer, where amacrine, bipolar and ganglion cells interact; (2) to improve techniques that combine retrograde marking of ganglion cell somata with intracellular dye staining; (3) to identify the ganglion cell types that project to the optic tectum, where most complex ganglion cells are expected to project; (4) to identify and characterize the cholinergic amacrine cells, postulated as the excitatory driving input onto complex ganglion cells; (5) to identify and quantify the synaptic inputs to an individual complex ganglion cell. An HRP-stained morphological type, G15, shown to have a complex receptive field (directionally selective), is analyzed by serial section electron microscopic reconstruction and postembedding immunocytochemistry for the inhibitory neurotransmitters GABA and glycine. It can be concluded from this study that: (1) amacrines constitute the principal input to ganglion cells, whereas bipolar output is mainly onto amacrine cells. Amacrine to amacrine synaptic contacts greatly outnumber other types of synapses. Stratum 2 of the inner plexiform layer has the highest overall absolute number of synapses, a feature that appears to be evolutionarily conserved; (2) most of the small, medium and large morphological retinal ganglion cell types project to the dorsolateral optic tectum; (3) the turtle retina contains three types of choline acetyltransferase-immunoreactive amacrine cells distinguished according to cell body location in the inner nuclear or ganglion cell layers and dendritic stratification levels in the inner plexiform layer; (4) synaptic input to dendrites near the G15 cell body is heavy and predominantly from amacrine cells. GABAergic inputs are scarce and glycinergic inputs were not found, nor were bipolar inputs in the periphery of the dendritic tree. Strong asymmetries thus appear in the distribution of synapses, which may play an important role in the genesis of complex, directionally selective receptive fields. Thus, this dissertation makes a contribution towards understanding how complex visual receptive fields are structurally formed in the submammalian retina.

description: Current solutions for switching between cellular networks and WiFi, such as those provided by Google and Samsung, do not work well in many scenarios. For example, a Samsung Galaxy S4 smartphone connected to a WiFi network remains in the WiFi mode for more than 5 minutes, even when the Internet connectivity beyond the first hop is unavailable. Therefore, there is a strong need for an efficient and automated switching mechanism between WiFi and cellular networks that has wide applicability. We design an adaptive, energy-efficient methodology to switch between WiFi and cellular networks to provide robust Internet connectivity. When using a WiFi network, we utilize a combination of active and passive monitoring techniques to detect unavailability of Internet connectivity via WiFi. When using the cellular network, we design two algorithms, namely the dormant probing algorithm, and a variable heartbeat probing algorithm, to detect the availability of Internet connectivity via WiFi. We implement the algorithms and mechanisms we design on smartphones. We also implement the capability of simultaneously accessing WiFi and cellular networks on smartphones. We evaluate our design and implementation using an Internet availability simulator which is based on a two-state continuous time Markov chain. Our experimental results show that we are able to detect unavailability of Internet connectivity beyond the first hop when using WiFi and switch to the cellular network fairly quickly. Furthermore, with the variable heartbeat algorithm, we are able to switch back to WiFi within 60 seconds of Internet connectivity becoming available, 90% of the time, with minimal probing overhead.

Data placement for efficient main memory access

description: The main memory system is a critical component of modern computer systems. Dynamic Random Access Memory (DRAM) based memory designs dominate the industry due to mature device technology and low cost. These designs, however, face several challenges moving forward. These challenges arise due to legacy DRAM device design choices, advances in Central Processing Unit (CPU) design, and the demand for higher memory throughput and capacity from applications. Due to the cost-sensitive nature of the DRAM industry, changes to the device architecture face significant challenges for adoption. There is thus a need to improve memory system designs, ideally without changing the DRAM device architectures. This dissertation addresses the challenges faced by DRAM memory systems by leveraging data management. Historically, data management/placement and its interaction with the memory's hardware characteristics have been abstracted away at the system software level. In this dissertation, we describe mechanisms that leverage data placement at the operating system level to improve memory access latency, power/energy efficiency, and capacity. An important advantage of using these schemes is that they require no changes to the DRAM devices and only minor changes to the memory controller hardware. The majority of the changes are limited to the operating system. This thesis also explores data management mechanisms for future memory systems built using new 3D stacked DRAM devices and point-to-point interconnects. Using the schemes described here, we show improvements in various DRAM metrics. We improve DRAM row-buffer hit rates by co-locating parts of different Operating System (OS) pages in the same row-buffer. This improves performance by 9% and reduces energy consumption by 15%. We also improve page placement to increase opportunities for power-down. This enables a three-fold increase in memory capacity for a given memory power budget. We also show that page placement is an important ingredient in building efficient networks of memories with 3D-stacked memory devices. We report a performance improvement of 49% and an energy reduction of 42% with a design that optimizes page placement and network topology.

Note. Endrödi (1966a: 188) records Cyclocephala distincta for “Guayana,” which is translated to Guyana in Endrödi (1985a: 71) and then repeated in Moore et al. (2018b: 171). The only other mentioning for the Guianas is by Duranton (2011: 12), who doubts its presence in French Guiana. Because of the lack of any recent records from the research area, we regard its occurrence there as doubtful and in need of confirmation.

description: It is well known that corrosion and simultaneous cyclic loading have a detrimental impact in the integrity of devices or structures. Understating these mechanisms is critical to ensure safety of aircraft. This work presents an extensive literature review on issues of corrosion mechanisms including pitting, exfoliation and intergranular attack. Moreover, models for phases of life and pitting corrosion are presented. Relevant definitions related to these failure modes are presented. The nucleation of fatigue cracks from corrosion pits was investigated by evaluating the effects of two variables on the fatigue life of dog-bone specimens of aluminum alloys 7075-T6 and 2024-T3. The specimens were exposed to different levels of corrosion in an acidified saline solution of 3.5% NaCl. In addition, the specimens were exposed to concomitant fatigue and corrosion until failure by fracture occurred. SEM analysis indicated that fatigue cracks formed/nucleated from each pit, and subsurface mechanisms of degradation were identified associated with the pitting nucleation sites including subsurface pitting, cracking, tunneling and intergranular attack. Failure data were analyzed by ANOVA methods and three transformations were evaluated to minimize the variance, including natural log, inverse square root and power with a lambda of 1/3. Contour and surface plots were developed to show how these variables impact the response of cycles to failure for the conditions evaluated. The effects of stress are more detrimental than corrosion time on the fatigue life of the specimens for the values previously defined by the DOE matrix. The research reported herein presents a methodology for accelerated corrosion fatigue of high strength aluminum alloys in an acidified saline environment. Subsequently a statistical based methodology to assess the impact of multiple variables into the fatigue life of specimens is presented. Statistical models are developed to assess the effect of two variables, stress and corrosion time into the fatigue life of the specimens. Stress levels were chosen to simulate conditions of current aircraft, such as fuselage bulkheads in the F-16. Development of statistical models to predict the behavior of materials will increase our ability to predict and prevent catastrophic structural failures thereby increasing the safety of our aircraft structures.

Species specificity of a Group B streptococcal enzyme that cleaves and inactivates C5a

description: Group B streptococcus (GBS) infections are often associated with a poor acute cellular response. Previous studies showed that GBS inactivate the complement-derived chemotactic activity in human zymosan-activated serum for human polymorphonuclear leukocytes (PMNs). Most strains of GBS were found to possess this ability to inactivate C5a and C5adesarg, the major complement-derived chemoattractants, and this enzymatic activity was termed C5a-ase. Subsequent studies showed that GBS C5a-ase executes this inhibitory activity by cleavage of a hep tapep tide from the carboxy terminus of C5a and the C5a-ase has been purified to homogeneity. The present studies investigated the ability of the GBS C5a-ase to inactivate the C5a chemoattractants of different animal species in vitro, including human, monkey, rat, rabbit, sheep, guinea pig and cow. Animal C5a was partially purified from zymosan-activated serum by 1 N HC1 precipitation and in some cases, further purification was achieved by gel-filtration on Sephadex G-75. The ability of GBS to inactivate the partially purified C5a was assessed in vitro using human PMN adherence and chemotaxis as indicators of C5a activity. Human, monkey and bovine C5a as well as recombinant human C5a (rhC5a) were inactivated by C5a-ase containing strains of GBS. In contrast, C5a prepared from rat, rabbit, sheep, and guinea pig appeared to retain full chemotactic activity for human PMNs after exposure to C5a-ase containing GBS. We also found that GBS did not inactivate rat or sheep C5a chemotactic activity when chemotaxis was assayed using rat or sheep PMNs, respectively.  Finally, we showed that PMN accumulation in rat skin in vivo to rat C5a was not affected by treatment with GBS. These data suggest that GBS C5a-ase exhibits species specificity in its ability to inactivate C5a.

description: The therapeutic manipulation of glutathione (GSH) levels is important in cases where toxic agents cause GSH depletion.   GSH depletion causes deleterious effects inside cells, as this thiol serves may protective roles.  One way to increase intracellular GSH level is to supply cysteine, the rate-limiting precursor in GSH biosynthesis.  Cysteine is known to be toxic to cells and therefore, cannot be administered directly.  To overcome this toxicity, cysteine can be delivered in a produg form.  The development of cysteine prodrugs had been found to be clinically relevant, especially during GSH depletion caused by acetaminophen (APAP).  One class of cysteine prodrugs, 2-alkyl-thiazolidines, has proven to be useful delivery agents.  Described here are four novel 2-alkylthiazolidines.  The amide and ethyl ester of 2(R,S)-D-gluco1',2',3,'4',5'-pentahydroxypentylthiazolidine-4(R)-carboxylic acid (GlcCys amide and GlyCys ethyl ester) and 2(R,S)-D-ribo-1',2',3',4'-tetrahydroxybutylthiazolidine-4(r)-carboxylic and (RibCys amide and RibCys ethyl ester) were synthesized and assayed for their protective capabilities.  To test compounds against APAP-induced toxicity, a cell assay using HepG2 cells and the toxin 2,6-dimethyl-N-acetyl-p-benzoquinoneimine (2,6-diMeNAPQI), a synthetic analog of a reactive APAP metabolite, was utilized.  GlcCys ethyl ester, RibCys amide, and GlcCys amide were proven to protect against 2,6-diMeNAPQI-induced toxicity.  This protection was dependent on intracellular process to activate the prodrugs evidenced by their lack of reaction with 2,6-diMeNAPQI in solution.  To further the understanding of these and other cysteine prodrugs and to facilitate the study of biological thiols in general, an HPLC assay that allows the concomitant separation and measurement of cysteine and GSH and their oxidized species was developed.  This assay showed that the prodrugs elevated cysteine but not GSH levels in HepG2 cells.  These results indicate that the novel prodrugs are attractive lead compounds for further analysis as cysteine delivery vehicles to abate the toxicity of APAP overdose.

description: The optimization of novel stretchable fingernail sensors for detecting fingertip touch force direction is introduced. The fingernail sensor uses optical reflectance photoplethysmography to measure the change in blood perfusion in the fingernail bed when the finger pad touches a surface with various forces. This "fingernail sensing" technique involves mounting an array of LEDs (Light Emitting Diodes) and photodetectors on the fingernail surface to detect changes in the reflection intensity as a function of applied force. The intensity changes correspond to changes in blood volume underneath the fingernail and allow for fingertip force detection without haptic obstruction, which has several applications in the area of human-machine interaction. This dissertation experimentally determines the optimal optical parameters for the transmittance of light through the human fingernail bed. Specifically, the effect of varying the wavelength and optical path length on light transmittance through the nail bed are thoroughly investigated. Light transmittance through the human fingernail is optimized when using green light (525nm) and when placing optoelectronic pairs as close together as possible. The optimal locations of the optoelectronic devices are predicted by introducing an optical model that describes light transmittance between an LED and a photodiode in the fingernail area based on optical experimentation. A reduced configuration is derived from the optimal optoelectronic locations in order to facilitate iv the fabrication of the optimized fingernail sensor without significantly compromising the recognition accuracy. This results in an overall force direction recognition accuracy of 95%. Using novel fabrication techniques, we successfully build a stretchable fingernail sensor prototype, which fully conforms to the two-dimensional fingernail surface and is independent of its geometry. Namely, we overcome the challenges of patterning conductive lines on a stretchable substrate, and embedding rigid optical components in a stretchable platform while maintaining electrical conductivity. A finite element analysis is conducted to optimize the electrical contact resistance between the optoelectronic components and underlying stretchable conductors, as a function of the bending curvature and substrate thickness. The functionality of the stretchable sensor is tested in relation to the design parameters. Finally, applications and potential impacts of this work are discussed.
Functions of the pointed domain within the ETS gene family

Subjects: Transcription Factors

description: All members of the ets family of transcription factors conserve the DNA binding ETS domain that recognizes the core sequence 5'-GGA(A/T)-3'.  Despite conserving this domain, individual ets proteins can perform specific functions.  Many unique features exist among ets proteins that establish this diversity.  One feature, the Pointed (PNT) domain, is a region of 80 amino acids conserved among only a subset of ets proteins.  The function of the PNT domain is not clear, but it is proposed to mediate hemotypic and heterotypic protein-protein interactions.  This thesis investigates the function of the PNT domain of four ets proteins.  Surprisingly, this domain was found to serve different functions within the family.  First, PNT domains can have different oligomeriazation states.  The Fts-1 PNT domain, composed of five alph helices that assume a globular fold, is monomeric in solution.  In contrast, the PNT domain of the ets family member TEL formed multimers under a variety of in vitro conditions.  Second, PNT domains have different protein partners.  In an affinity chromatography experiment, a fragments of Ets-1 spanning the PNT domain an MAPK site bound the mitogen-activated protein kinases (MAPKs) ERK1 and/or ERK2.  These kinases phosphorylate Ets-1 and Ets-2 at a MAPK site N-terminal to the PNT domain.  Kinase assays identified docking site on the surface of the PNT domain of Ets-1 important for interacting with ERK2 and Ras/MAPK signaling.  The docking site is conserved in sequence and in function in the PNT domain of Ets-2 but not in the PNT domain of the ets family member GABPalph.  The docking site sequence is also not well-conserved in other PNT domains.  These results highlight the PNT domain as a conserved structureal element whose distinct surface features generate specificity of function among ets proteins.

Note. The record of Cyclocephala epistomalis for French Guiana in Moore et al. (2018b: 174) is copied from Gruner (1971: 845), who lists it as C. mollis. The only other record for the research area is for Manaus in the Brazilian state of Amazonas in Endrödi (1966a: 261) (as C. mollis). Many identifications made by Gruner (1971) appear to be incorrect, and we consider the record of this species for French Guiana doubtful.

description: The purpose of this study was to determine if a planned intensive preoperative nursing intervention would reduce the anxiety level of the patient preparing to undergo cholecystectomy surgery and would assist in an uneventful postoperative recovery.  Intensive preoperative nursing care was defined as a planned preoperative program, which consisted of establishing a line of communication with the patient prior to surgery; allowing the patient to ventilate his feelings; ascertaining his level of knowledge; clarifying his misconceptions and explaining to him the expected pre- and postoperative procedures.  The evening prior to surgery,, the investigator administered the intensive nursing care program to each patient in the experimental group.  The Mood and Feelings Inventory and the Hospital Reaction Questionnaire (Quinn, Wolfer and Davis, I969), were used to measure the pre- and postoperative anxiety levels of the control, and experimental groups (15 in number).  The postoperative complications of the number of narcotics and sedatives; the episodes of vomiting; anorexia and urinary problems were tabulated.  The data were collected on all patients prior to surgery and on the sixth postoperative day.  The t test was used to determine if there was a significant difference in the mean scores between the control and experimental groups.  The findings showed that the preoperative intensive nursing care program did not make a significant difference in the anxiety level of the groups. There was, in regard to complications, a significant difference in the frequency of postoperative vomiting ( P =

description: The education of a general surgeon requires 5 to 6 years after the completion of medical school.  The training is unique in that it consists of training in both cognitive and technical skills.  A Surgery Residency Program must provide an adequate and balance exposure to the full variety of operative procedures that comprise General Surgery.  A computer program has been developed to help the Residency program Director accurately and efficiently track the operative experience of residents.  This  program will facilitate scheduling so that each resident will have an adequate operative experience and so that balance within the program among the residents can be achieved.  Programs for Residents' Operative Performance in Surgery (PROPS) is an efficient, accurate, inexpensive and easy-to-use personal computer based software system that ill capture and store resident's operative data by case, automatically tabulate statistical data relative to the operative experiences of residents, provide management reports for use by the Residency Program Director, facilitate the transfer of Chief Resident data electronically to the Residency Review Committee for General Surgery, and prepare a report to the Board of Surgery for each Chief Resident.  In addition, The PROPS system provides an intelligent consulting function to fulfill an even case distribution.  This consulting function will help the director to quickly and easily obtain the needed information to make decision regarding resident assignment.  The PROPS system has proven to satisfy the Department of Surgery's need for resident operative experience record keeping and report making.  After completion of these tasks, a comprehensive tabulation of residents' operative experience at each level of their training program will be developed.  This experience with the PROPS system using a relational Data Base Management System (DBMS) is being extended to a larger environment where information is gathered from multiple sources.  Specifically, the PROOS system has potential to help with operating room decisions such as scheduling, supplies, room utilization, and reporting.

A pergunta-chave é: qual é a taxa de aproveitamento dos votos de todos os brasileiros? Uma taxa reduzida simplesmente mostraria que é inócua a costumeira provocação sobre se lembramos ou não em quem votamos no passado. Afinal, se poucos votos fossem efetivamente aproveitados, qual seria o proveito de semelhante lembrança? No intuito de responder a essas questões, analisaremos as últimas eleições para a Câmara dos Deputados, em 2010. Os dados usados foram extraídos do site do Tribunal Superior Eleitoral (TSE).
