Gonadotrophic control of follicular development and function during the oestrous cycle of the ewe. (1981)

In the adult non-pregnant ewe the secretion of FSH is sufficient to ensure a continuous growth and development of antral follicles to 3-5 mm size at all times. Further development and increased secretion of oestradiol through the final 72 h to ovulation depends on adequate stimulation by LH. During anoestrus and the luteal phase of the cycle LH pulses occur too infrequently to stimulate sufficient oestradiol to evoke an LH surge. Moreover, during the luteal phase progesterone secreted by the corpus luteum not only reduces the frequency of LH pulses but also inhibits the ability of oestrogen to evoke an LH surge. At the time of luteal regression the frequency of LH pulses increases to at least one per hour due to the fall in progesterone secretion. This change in pulse frequency of LH is associated with a decrease in the secretion of FSH, probably because of a direct inhibitory action of oestrogen on the anterior pituitary gland. The dominant follicle is probably relatively independent of circulating levels of FSH due to the high concentration of oestradiol and FSH within the microenvironment of the follicular cavity. Once the oestrogen secretion achieves a certain level a preovulatory surge of LH (and FSH) occurs. Increased sensitivity of the anterior pituitary to LH-RH and increased secretion of LH-RH from the hypothalamus both play a part in producing the LH surge. The rise in prolactin at this time probably reflects a decrease in hypothalamic dopamine turnover which is necessary for maximum release of LH-RH. The preovulatory LH surge initially stimulates and then totally inhibits further secretion of oestrogen and androgen from the ovulatory follicle. This suppression of steroid secretion is accompanied by a second peak of FSH at about the time of ovulation. The function of this second peak of FSH remains unknown although it may be responsible for the development of the large antral follicles which occur on Days 3 and 4. It is probably more important in those mammals like the rat and hamster which only form a functional corpus luteum if pregnancy occurs and in which oestrogen is necessary for implantation.
Foaming in radioactive waste treatment and immobilization processes. 1998 annual progress report (1998)

'The objective of this research is to gain a basic understanding of the mechanisms that produce foaming during nuclear waste treatment, to identify the key parameters which aggravate foaming, and to identify effective ways to eliminate or mitigate foaming. The specific goal of this part of the study is to reveal the role of solid particles in colloidal range in foam formation and foam stability. The result of this study will aid in eliminating foaminess in three-phase gas/liquid/solid systems, thereby facilitating implementation of environmental technologies for radioactive waste treatment and waste immobilization processes. This report summarizes work completed during the first year of a three-year project. To characterize the foam and identify key parameters for foaminess in a three-phase gas/liquid/solid system, a simulated (non-radioactive) acidified sludge was used. The sludge samples were prepared using PUREX sludge simulant and PHA (Precipitate Hydrolysis Aqueous) was prepared using irradiated precipitate. The pH of the sludge samples was 6.0--6.5 and pH of PHA was 4.0. Both of these samples were prepared at Savannah River Technical Center (SRTC) and were shipped to the laboratory at Illinois Institute of Technology, Chicago. The sludge contained Al (3.8 wt%), Hg (3.5 wt%), Fe (25.5 wt%) on dry basis and noble metals (Rh, Ru, Pd, Ag, Se) in small concentrations. The sludge particles were polydispersed in size varying from about 0.05\265m to 10\265m. Such a sludge sample is a good model representation of actual nuclear sludge. However, the preparation of sludge in terms of its constituents affects the foaminess.'
Accurate description of the light self-diffraction on high modulated dynamic gratings in semiconductor materials (1995)

The light self-diffraction in the case of the high modulated phase gratings induced in semiconductor materials is studied by solving numerically the set of the coupled wave equations, which were used previously for gratings produced by linear phenomena. We have extended this formalism to include the case of the absorbing materials and the nonuniformity of the interfering laser beams, which induce the gratings. Finally, we compare this description with our experimental data obtained in the self-diffraction on the phase gratings induced in crystalline silicon wafers by Nd:YAG laser beams. The experimental results are fitting better our theoretical description.
The cation channel TRPA1 tunes mosquito thermotaxis to host temperatures (2015)

While most animals thermotax only to regulate their temperature, female mosquitoes are attracted to human body heat during pursuit of a blood meal. Here we elucidate the basic rules of Aedes aegypti thermotaxis and test the function of candidate thermoreceptors in this important behavior. We show that host-seeking mosquitoes are maximally attracted to thermal stimuli approximating host body temperatures, seeking relative warmth while avoiding both relative cool and stimuli exceeding host body temperature. We found that the cation channel TRPA1, in addition to playing a conserved role in thermoregulation and chemosensation, is required for this specialized host-selective thermotaxis in mosquitoes. During host-seeking, AaegTRPA1(-/-) mutants failed to avoid stimuli exceeding host temperature, and were unable to discriminate between host-temperature and high-temperature stimuli. TRPA1-dependent tuning of thermotaxis is likely critical for mosquitoes host-seeking in a complex thermal environment in which humans are warmer than ambient air, but cooler than surrounding sun-warmed surfaces.
Using term rewriting to verify software (1994)

This paper describes a uniform approach to the automation of verification tasks associated with while statements, representation functions for abstract data types, generic program units, and abstract base classes. Program units are annotated with equations containing symbols defined by algebraic axioms. An operation's axioms are developed by using strategies that guarantee crucial properties such as convergence and sufficient completeness. Sets of axioms are developed by stepwise extensions that preserve these properties. Verifications are performed with the aid of a program that incorporates term rewriting, structural induction, and heuristics based on ideas used in the Boyer-Moore prover. The program provides valuable mechanical assistance: managing inductive arguments and providing hints for necessary lemmas, without which formal proofs would be impossible. The successes and limitations of our approaches are illustrated with examples from each domain.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Intrinsically Disordered Side of the Zika Virus Proteome (2016)

Over the last few decades, concepts of protein intrinsic disorder have been implicated in different biological processes. Recent studies have suggested that intrinsically disordered proteins (IDPs) provide structural plasticity and functional diversity to viral proteins that are involved in rapid replication and immune evasion in host cells. In case of Zika virus, the roles of protein intrinsic disorder in mechanisms of pathogenesis are not completely understood. In this study, we have analyzed the prevalence of intrinsic disorder in Zika virus proteome (strain MR 766). Our analyses revealed that Zika virus polyprotein is enriched with intrinsically disordered protein regions (IDPRs) and this finding is consistent with previous reports on the involvement of IDPs in shell formation and virulence of the <i>Flaviviridae</i> family. We found abundant IDPRs in Capsid, NS2B, NS3, NS4A, and NS5 proteins that are involved in mature particle formation and replication. In our view, the intrinsic disorder-focused analysis of ZIKV proteins could be important for the development of disorder-based drugs.

Passive transfer studies with type II collagen antibody in b10.D2/old and new line and C57b1/6 normal and beige (chediak‐higashi) strains: evidence of important roles for C5 and multiple inflammatory cell types in the development of erosive arthritis (1987)

C5-normal B10.D2/new line mice were susceptible to passively transferred arthritis from purified type II collagen antibody, and in vitro studies demonstrated that, when bound to cartilage, this antibody readily activated complement C5 to C5a. C5-deficient B10.D2/old line mice failed to develop passively transferred arthritis, despite the deposition of antibody and C3 along the cartilage surface. C57Bl/6 mice were susceptible to passively transferred arthritis, which was characterized in histopathologic studies as an erosive synovitis involving multiple inflammatory cell types. In contrast, neither clinical nor histologic evidence of arthritis was observed in C57Bl/6 mice with the beige mutation (Chediak-Higashi syndrome).
Effect of different adhesive strategies on microtensile bond strength of computer aided design/computer aided manufacturing blocks bonded to dentin (2016)

[Effect of glutamic acid palmitamide or linoleamide on convulsions induced by pentetrazole]. (1989)

Female Balb-C mice received glutamic acid palmitamide (PGt) or linoleamide (LGt) at doses included between 10 and 135 mg.kg-1 (i.p.) and, 90 min after these injections, pentetrazol (PTZ) at 90 mg.kg-1, i.p. PGt (10 or 100 mg.kg-1, i.p.) reduced significantly latencies of first convulsions and lethality and increased the intensity of convulsions after PTZ. This effect disappeared at 135 mg.kg-1, i.p. and, at high doses (up to 150 mg.kg-1, i.p.) PGt antagonized the PTZ convulsions. LGt (10 mg.kg-1, i.p.) had not any significant effect on the PTZ convulsions and antagonized them when administered at a dose of 100 mg.kg-1, i.p. These results, as well as them obtained with PGt and LGt on the haloperidol or reserpine catalepsy, could be the reflection of the preferential impact of LGt in the striatum and of PGt in the limbic structures and in the substantia nigra. At high doses these compounds could reach brain regions with low density of glutamatergic receptors (thalamus, reticular formation) and develop an activating effect able to antagonize the propagation of the PTZ convulsions. These preferential impacts could augur an antiepileptic action for LGT and a promnesient effect for PGt and LGt.
Formation of the Lunar Atmosphere (1974)

Measurements of Ar-40 and helium made by the Apollo 17 lunar surface mass-spectrometer are used in the synthesis of atmospheric supply and loss mechanisms. The argon data indicate that about 8% of the Ar-40 produced in the moon due to decay of K-40 is released into the atmosphere and subsequently lost. Variability of the atmospheric abundance of argon requires that the source be localized, probably in an unfractionated, partially molten core. If so, the radiogenic helium released with the argon amounts to 10% of the atmospheric helium supply. The total rate of helium escape from the moon accounts for only 60% of the solar wind particle influx. This seems to require a nonthermal escape mechanism for trapped solar-wind gases, probably involving weathering of exposed soil-grain surfaces by solar-wind protons.
Squamous carcinoma in the liver. (1990)

Squamous carcinoma of the liver has only rarely been reported. We present a case which highlights not only the difficulties in diagnosis but also how it can closely mimic sclerosing cholangitis.
Parvovirus B19‐associated catastrophic endothelialitis with a Degos‐like presentation (2008)

Parvovirus B19 is a single-stranded DNA virus exhibiting affinity for a variety of cell types including endothelial cells. The basis of the affinity is globoside expression, the receptor for B19. B19 endothelial cell parasitism accelerates endothelial cell apoptosis, potentially critical in inducing neoantigenicity and secondary antibody formation. A 38-year-old previously healthy male developed intestinal and cutaneous infarction, elevated creatinine phosphokinase (CPK) levels and progressive cytopenias. The basis of his clinical presentation was unclear until a skin biopsy suggested a potential role for virally mediated endothelial cell injury. Hematoxylin and eosin, immunohistochemical, immunofluorescent and reverse transcriptase in situ polymerase chain reaction studies were conducted on skin biopsies to assess for viral triggers. B19 viremia and localization of B19 RNA transcripts to vascular endothelium were uncovered. A diagnosis of catastrophic endothelial cell injury attributable to B19 infection was rendered. The patient showed significant improvement with intravenous immunoglobulin (IVIG). Parvovirus B19 is a ubiquitous virus that in the majority of affected patients remains asymptomatic. Nevertheless, because of its ability to infect endothelium it can cause severe multiorgan endothelial cell injury.
Facile Fabrication of a Potential Slow-Release Fertilizer Based on Oxalate-Phosphate-Amine Metal-Organic Frameworks (OPA-MOFs) (2018)

This work demonstrates a simple, reproducible and scalable method of producing a potential slow-release fertilizer material. In this study, oxalate-phosphate-amine metal organic frameworks (OPA-MOFs) powder was synthesized from the hydrothermal treatment of ferric chloride (FeCl3•6H2O), orthophosphoric acid (H3PO4), oxalic acid dihydrate (H2C2O4•2H2O), and a common fertilizer, urea (CO(NH2)2). Being a structure directing agent (SDA)-type of MOF, the material is expected to slowly release urea via cation exchange, and eventually trigger the collapse of the framework, thus resulting to the subsequent release of the phosphates and iron-oxalate complexes. Elemental analysis revealed that the synthesized samples contains a promising amount of incorporated nitrogen and phosphorus. In this particular study, increasing in the amount of urea during the synthesis however revealed minimal change in the %N in the final product which tells us that maximum loading has already been achieved. P and N release experiments shall still be done both in vitro and in actual soil samples to monitor the release delivery kinetics and efficiency of the OPA-MOFs for fertilizer release applications.
Geriatric Teams in the Long-term Care Facility (1988)

Geriatric teams have emerged as an accepted method of health care delivery to the elderly patient in ambulatory and acute inpatient settings. As one model of specialized health care teams, geriatric teams vary in structure, membership, and type. The purposes may be diverse, ranging from providing primary care to multidimensional functional and diagnostic assessment. Geriatric teams have convincingly demonstrated benefit to the care of the elderly. Overcoming significant barriers to their formation, geriatric teams are beginning to develop in long-term care facilities as a result of economic and educational pressures. However, the unique environment and needs of the long-term care facility have resulted in differences in leadership, membership, and structure of long-term care teams. Pharmacist involvement in the long-term care geriatric team could benefit the facility, patient care, and the profession. The key to future involvement by pharmacists in teams appears to depend on their interest, ability to acquire necessary skills, and demonstration of unique professional contributions.
Strategic recovery requires leadership (2010)

The MCR of prednisolone (11 beta,17,21-trihydroxypregn-1,4-diene-3,20-dione) and the absorption of prednisone (17,21-dihydroxypregn 1,4-diene-3,11,20-trione) were studied in five normal subjects and four patients. Plasma and urinary prednisolone were measured by a competitive radioassay. The MCR was determined after iv administration of 30 mg nonisotopic prednisolone using one-compartment (MCR1) and two-compartment (MCR2) analyses. These values were compared with the MCR determined after oral administration of nonisotopic prednisone (MCR0). MCR1 and MCR2 were closely correlated, indicating the applicability of first order kinetics to the study of prednisolone metabolism. In subjects with normal gastrointestinal function, MCR0 was consistently lower than MCR2 (mean MCR2 = 0.175 liters/h.kg; MCR0 = 0.145 liters/h.kg). In two patients with steroid malabsorption, the MCR0 was significantly greater than MCR2. Knowledge of the expected relationship between MCR0 and MCR2 allowed quantitation of the degree of malabsorption. With or without impaired absorption, the absorptive process was essentially complete by the time of the peak plasma concentration. Estrogen therapy lowered the MCR0, and high prednisone dose increased the MCR0. Those effects and the effects of iv prednisolone administration on the MCR are explained by the effects of plasma protein binding of prednisolone. These studies demonstrate the usefulness of the oral MCR determination in the evaluation of steroid absorption and metabolism.
Two-dimensional weight-constrained codes through enumeration bounds (2000)

For a rational /spl alpha//spl isin/(0,1), let /spl Ascr//sub n/spl times/m,/spl alpha// be the set of binary n/spl times/m arrays in which each row has Hamming weight /spl alpha/m and each column has Hamming weight /spl alpha/n, where /spl alpha/m and /spl alpha/n are integers. (The special case of two-dimensional balanced arrays corresponds to /spl alpha/=1/2 and even values for n and m.) The redundancy of /spl Ascr//sub n/spl times/m,/spl alpha// is defined by /spl rho//sub n/spl times/m,/spl alpha//=nmH(/spl alpha/)-log/sub 2/|/spl Ascr//sub n/spl times/m,/spl alpha//| where H(x)=-xlog/sub 2/x-(1-x)log/sub 2/(1-x). Bounds on /spl rho//sub n/spl times/m,/spl alpha// are obtained in terms of the redundancies of the sets /spl Ascr//sub /spl Lscr/,/spl alpha// of all binary /spl Lscr/-vectors with Hamming weight /spl alpha//spl Lscr/, /spl Lscr//spl isin/{n,m}. Specifically, it is shown that /spl rho//sub n/spl times/m,/spl alpha///spl les/n/spl rho//sub m,/spl alpha//+m/spl rho//sub n,/spl alpha// where /spl rho//sub /spl Lscr/,/spl alpha//=/spl Lscr/H(/spl alpha/)-log/sub 2/|/spl Ascr//sub /spl Lscr/,/spl alpha//| and that this bound is tight up to an additive term O(n+log m). A polynomial-time coding algorithm is presented that maps unconstrained input sequences into /spl Ascr//sub n/spl times/m,/spl alpha// at a rate H(/spl alpha/)-(/spl rho//sub m,/spl alpha///m).
Nonlinear Molecular Reorientation of Polymer-Stabilized Dye-Doped Liquid Crystals by Depolarized Laser Beam (2020)

Liquid crystals (LCs) are the innovative materials that can control their molecular orientation using an optical field with a laser beam. However, the molecular orientation has been explored only by a polarized laser beam. In this study, we report the molecular reorientation of oligothiophene-doped LCs by an irradiation with a focused depolarized laser beam that has a spatial polarization pattern. Two self-diffraction rings occurred by nonlinear molecular reorientation induced by the irradiation with the focused depolarized laser beam. The threshold intensities measured by the focused depolarized laser beam were two times higher than that of the linearly polarized laser beam.
Quantitative Analysis of Vestibular Function in Normal Adults (1995)

The maintenance of body equilibrium and posture depends on information from vestibular system, vision, proprioceptive system and other sensory organs. These informations are integrated in the central nervous system and relay on the eye muscles through vestibulo- ocular reflex, postural muscles through vestibulo-spinal reflex. Quantitative analysis of vestibular function has been extensively evaluated on the vestibulo-ocular reflex beause it is the easiest reflex to stimulate and record. The caloric test by Fitzgerald-Hallpike method using 250ml amount of water, 30°C cold, 44°C warm and rotation test by sinusoidal rotation stimuli using frequency of 0.05, 0.1, 0.2Hz. were performed to evaluate the vestibular function in 23 adults. The obtained results were as follows: Vestibulo-ocular reflex induced by bithermal caloric stimuli was quantified in values of maximum velocity of slow component, amplitude, canal paresis and directional preponderance. Maximum velocity of slow component was 26.4±2.3~28.9±1.4°/sec(Mean±SE), maximum amplitude was 7·6±0.7 ~ 8.7±0.9°. Also, canal paresis was 6.1±1·2% and directional preponderance was 4.9±1.4% within normal range. The direction of nystagmus induced by sinusoidal rotation stimuli was the same to the direction of rotation and the velocity of nystagmus was proportioned to the velocity of rotation. Gain, phase difference and directional preponderance were calculated. Gain was 0.62±0.02 at frequency of 0.05Hz, 0.6410.03 at 0.1Hz, 0.59±0.01 at 0.2Hz and phase difference was 28.5± 0.7° at 0.05Hz, 19.1±0.8° at 0.1Hz, 12.2±0.5° at 0.2Hz, directional preponderance was 3.0, 0.4~5.5±1.2%.
