Successful treatment of tinea capitis with 2% ketoconazole shampoo (2000)

Ketoconazole 2% shampoo alone reduces the number of viable arthroconidia in children with tinea capitis thus reducing the transmissibility and contagious nature of the disease. Unexpectedly, complete cure was obtained in 5/15 (33%) of the children. The children remained clinically and mycologically clear as long as one year after treatment.
Secretory Leukocyte Protease Inhibitor Binds to <i><scp>N</scp>eisseria gonorrhoeae</i> Outer Membrane Opacity Protein and is Bactericidal (2012)

We conclude that SLPI is bactericidal for gonococci and is expressed by reproductive tract epithelial cells and thus is likely to play a role in the pathogenesis of gonococcal infection.
Severity of Neuropathy Is Associated With Long-term Spinal Cord Stimulation Outcome in Painful Diabetic Peripheral Neuropathy: Five-Year Follow-up of a Prospective Two-Center Clinical Trial (2017)

SCS is successful in reducing chronic pain symptoms in the lower extremities of patients with PDPN up to 5 years after initiation of treatment. Furthermore, 80% of patients with PDPN still use their SCS device after 5 years. Moreover, the severity of neuropathy is associated with a higher chance of long-term treatment failure during a 5-year follow-up.
Design of a New In-Pipe Inspection Robot (2014)

Basically robots are designed in such way that they remove human intervention from labour intensive and hazardous work environment, sometimes they are also used to explore inaccessible work places which are generally impossible to access by humans. The inspection of pipe comes in same category because they carry toxic chemicals, fluids and most of the time has small internal diameter or bends which become inaccessible to human. The complex internal geometry and hazard content constraints of pipes demand robots for inspection of such pipes in order to check corrosion level of pipe, recovery of usable parts from pipe interior, sampling of sludge and scale formation on pipe internal surface etc. Several designs of In-pipe inspection robots (IPIR) have been proposed in the literature to solve the problems related with inspection of these complicated internal geometries. Designing of an in-pipe inspection robot (IPIR) is a difficult task and hence the designer must take care of the design issues like Mobility, Steer ability, Turning radius, Size and shape adaptability, Online adaptability, Flexibility, Stability, Autonomous operation and obstacle avoidance, Efficiency at uneven surface, Safe operation, Material selection, Type of task to be performed inside the pipe, Number of actuators, Operation in active pipe line, Retrieval of robot, User friendly navigation and control system, Range of operation, Quantitative analysis of defects inside the pipe. Based on above, this research work presents investigations into design issues pertaining to development of In-pipe inspection robotics and proposes a new model of an In-pipe inspection robot to overcome some critical design issues. This proposed model is a screw drive type wall press adaptable wheeled In-pipe inspection robot. It is able to move through vertical, horizontal pipes and it can easily pass through elbow of a pipe line. This model comprises of three modules- rotor, stator and control unit. The Rotor module has three wheels mounted on the outer periphery with a helix angle of 15°. Wheels of rotor follow the helical path on the internal surface of pipe line and move in the longitudinal direction inside the pipe. A geared DC motor of 200RPM is connected to rotor by a flexible sleeve coupling. Due to its flexibility motor can transmit torque to rotor even in case of minor misalignments and can easily be stopped at any point of journey inside the vertical or horizontal pipeline, thereby eliminating the need of braking system to achieve stability. Stator module is the housing of motor and it contains three spring loaded wheels on the outer periphery. Control Module of robot consist battery and wireless control unit. Spring loaded wheels of rotor and stator provide it shape adaptability and enhance friction between wheels and pipe interior.
SDMA: On The Suitability for VANET (2008)

Medium access control (MAC) is critical for vehicular ad hoc networks (VANET). A real commercial VANET system has not come into the market. Different MAC schemes have been proposed to attempt to achieve the expected performance, such as bounded delay, high packet reception rate, security, etc. Space Division Multiple Access (SDMA) is one of the VANET MAC proposals and has been theoretically investigated. However, it has not been studied whether SDMA is realistically feasible in VANET. In this paper, the suitability of SDMA for VANET is studied. The core mechanisms of the proposed SDMA and of the possible SDMA functions for VANET are analyzed and evaluated. Concerns upon practical implementation issues and theoretical limits are presented, based on which the conclusion of the unsuitability of SDMA for VANET is drawn.
O‐Glycoside Orientation Is an Essential Aspect of Base J Recognition by the Kinetoplastid DNA‐Binding Protein JBP1 (2007)

A binding edge? Comparison of dissociation constants and molecular-dynamics snapshots of a panel of synthetic telomeric double-stranded DNA sequences containing HMdU O-glycosides has revealed that the DNA-binding protein of kinetoplastids, such as Leishmania and Trypanosoma, JBP1, recognizes a critical edge-on conformation of the pyranosyl ring of base J. If this conformation is perturbed, JBP1 binding is dramatically reduced.
Nonconventional three-wheel electric vehicle for urban mobility (2001)

This paper outlines the original solutions adopted for powering a nonconventional three-wheel electric vehicle. This is a lightweight vehicle for use in urban mobility with mission tasks such as 50 km/h cruising speed and 80 km range of autonomy. The propulsion system is based on a lead-acid battery-fed wheel direct drive. This is arranged with a 4.5 kW prototype of a slotless axial-flux permanent magnet machine, which has a total weight of 15 kg and is capable of 85 Nm continuous torque and 120 Nm peak torque over 2 min. The motor is totally enclosed in the single front wheel of the vehicle and fed through an IGBT bidirectional power converter, which allows the control of both motoring and regenerative braking operations. Design characteristics and experimental data taken from the prototype of wheel direct drive are given.

Isointegral analysis of body surface maps: surface distribution and temporal variability in normal subjects. (1981)

Isointegral analysis of body surface potential maps has been proposed as a useful approach to data reduction. To determine the normal magnitude and surface distribution of a series of time-integral measurements, we acquired body surface potential maps from 40 men and 15 women, ages 20-46 years, who were clinically normal. In a subset of 16 subjects, variability in serial maps was assessed as the root-mean- square difference in time-integral values between maps using the same electrode application (recordings separated by 15 minutes) as well as when different electrode applications were required (recordings separated by 1-7 days).
On the transfer of integral proteins into membranes. (1987)

We have earlier proposed a molecular mechanism for the translocation of hydrophilic proteins across membranes that accounts for the experimental facts and meets the restrictions that we stipulate for such a mechanism. In particular, the restrictions are that translocation occurs by successive segments of the polypeptide chain and that the ionic groups of the polypeptide remain in contact with water throughout the translocation process. The evidence indicates that the transfer of integral proteins into membranes very likely uses the same molecular machinery as does the translocation of hydrophilic proteins across membranes. Here we show how the mechanism we have proposed for translocation can also be utilized in the intercalation of known types of integral proteins, accounting for their specific topologies in the membrane.
Staining nucleic acids and proteins in electrophoresis gels (2001)

This review addresses the most widely used stains for gel electrophoresis in molecular biology today. A brief introduction to electrophoresis is given, followed by a description of agarose and acrylamide gel formation. The major stains for nucleic acids are described, most of which are fluorescent and intercalate into the double helix structure of the nucleic acids. An ultraviolet transilluminator is necessary to visualize the fluorescent bands. The major protein stains include Coomassie blue, silver, and commercial fluorescent stains. Negative staining also can be used to stain the gel background, leaving the protein bands of interest transparent and visible against a white background.
Effects of lateral scaling on power gain of multifinger SiGe power HBTs (2006)

The lateral scaling issues of high-power SiGe HBTs are analytically studied and verified using industry SiGe HBTs. It is found that due to increased parasitics in large-area power SiGe HBTs, f/sub max/ cannot be readily improved by only downscaling the emitter finger width. It is further found that without proper downscaling of the base stripe width, the maximum stable power gain (MSG) of power SiGe HBTs may be degraded by only shrinking the emitter finger width. It is thus proposed that both emitter finger width and the base stripe width ought to be downscaled properly in order to optimize the RF performance of SiGe power HBTs that are configured in a multiple subcell structure.
A calcineurin-like gene <i>ppb1</i> <i>+</i> in fission yeast: mutant defects in cytokinesis, cell polarity, mating and spindle pole body positioning (1994)

A calcineurin (type 2B)-like protein phosphatase gene designated ppb1+ was isolated from the fission yeast Schizosaccharomyces pombe. The predicted amino acid sequence was 57% identical to rat PP2B alpha. ppb1 null mutant could form colonies at 33 degrees C but the size of the colonies was small at 22 degrees C. Cytokinesis was greatly delayed at 22 degrees C, and a large number of multi-septate cells were produced. The cell polarity control was impaired, causing branched cells. ppb1 null was virtually sterile. These phenotypes were rescued by a plasmid carrying the ppb1+ gene. Multi-septate cells were also produced in wild type at 22 degrees C by cyclosporin A, an inhibitor of calcineurin. This drug effect was enhanced in stst1 null mutant, which was hypersensitive to various drugs and cations. ppb1 null was not affected by cyclosporin A, consistent with the hypothesis that ppb1 is its target. Double-mutant analysis indicated that ppb1 had a function related to that of two other phosphatases, type 1-like dis2 and 2A-like ppa2.ppb1 null-sts1 null showed the severe multi-septate phenotype in the absence of cyclosporin A. ppb1+ and sts1+ gene functions are related. The double mutant ppb1-sts5 was lethal, indicating that the ppb1+ gene shared an essential function with the sts5+ gene. Overexpression of ppb1+ caused anomalies in cell and nuclear shape, microtubule arrays and spindle pole body positioning in interphase cells. Thus the ppb1+ gene appears to be involved in cytokinesis, mating, transport, nuclear and spindle pole body positioning, and cell shape.
SPICE model for lossy piezoceramic transducers (1997)

A transmission line equivalent circuit for piezoelectric transducers has been modified to provide modeling of lossy piezoceramic transducers. A lossy transmission line is used to model the mechanical losses. The equivalent circuit parameters are derived from analogies between electrical transmission lines and acoustic wave propagation. Implementation of the equivalent circuit model in SPICE is shown. Simulations and measurements in the time and frequency domain of a low-Q material and a multilayered ultrasonic sensor using a low-Q piezoceramic transducer are presented.
Severe Acute Metabolic Acidosis and Wernicke's Encephalopathy Following Chemotherapy with 5-Fluorouracil and Cisplatin: Case Report and Review of the Literature (1996)

A 28-year-old woman with inoperable gastric carcinoma was given continuous infusion of 5-fluorouracil (5-FU) and low-dose cisplatin (CDDP) for 4 weeks while receiving intravenous hyperalimentation (IVH). Eleven days after her last treatment, she developed acute diplopia, deafness and gait ataxia, followed by severe confusion. She became markedly acidotic and hypotensive with a systolic blood pressure of 60 mmHg, necessitating intubation, dopamine treatment and hemodialysis for 7 h. She was also given thiamine. Thereafter, her blood pressure stabilized, the acidosis improved, and her deafness, diplopia, and confusion were resolved. This case suggests that FP (5-FU/CDDP) therapy toxicity, manifested as acute metabolic acidosis and Wernicke's encephalopathy, may be associated with IVH and thiamine deficiency.

The Great Out of the Small (2000)

This article discusses that a wealth of technological breakthroughs is likely to come from mimicking the interactions of biological systems and their response to the environment. The following next few decades will witness thinking, learning, evolvable aerospace systems. It will also see systems-on-a-chip, in which miniaturization allows all electronic systems of an aerospace vehicle (computer, memory, guidance, navigation, communications, power, and sensors) to fit on a tiny chip. Such aerospace systems cannot be realized with present technologies. The synergistic coupling of biotechnology, nanotechnology, and information technology with other leading edge aerospace technologies can produce breakthroughs in vehicle concepts and exploration missions, enable new science, and reshape our frame of reference for the future. The potential benefits of these technologies are pervasive and extend to several non-aerospace fields, such as high-performance computing and communications, land and sea transportation systems, health care, and advanced energy conversion and storage.
The mRNA-binding protein which controls ferritin and transferrin receptor expression is conserved during evolution (1990)

A post-transcriptional regulatory protein, termed iron regulatory factor (IRF), that binds specifically to the iron-responsive elements of ferritin and transferrin receptor mRNA, has recently been identified in the cytoplasm of human and mouse cells. Activation of this factor by low intracellular iron levels leads to inhibition of ferritin translation and an increase of TR mRNA stability. To investigate whether these feedback regulatory mechanisms are conserved during evolution, we analysed cytoplasmic extracts from 12 different species for a specific IRE-binding activity. We found mRNA-binding proteins in chicken, frog, fish and fly, which are equivalent to human and mouse IRF in gel-retardation assays with radiolabeled RNA transcripts. Competition experiments, molecular weight determinations, and modulation of the mRNA-binding activity in response to intracellular iron levels or reduction by beta-mercaptoethanol indicate that IRF has similar structural and functional properties in these different species.
Calculation of Risk of Colorectal and Endometrial Cancer Among Patients With Lynch Syndrome (2009)

Lifetime risks of CRC and EC in mismatch repair gene mutation carriers are high even after adjusting for ascertainment. These estimates are valuable for patients and providers; specialized cancer surveillance is necessary.
Microwave magnetoplasma resonances of two-dimensional electrons in MgZnO/ZnO heterojunctions (2015)

The plasma, magnetoplasma, and edge magnetoplasma excitations were investigated in two-dimensional electron systems hosted at the heterointerface of MgZnO/ZnO structures using optical detection of resonant microwave absorption. The magnetodispersion of the plasma excitations allowed the extraction of the electron effective mass. It was found to exhibit a surprisingly large dependence on the electron density, which is difficult to account for just from nonparabolicity effects.
DSCS III Receive Multiple Beam Antenna performance improvement (2002)

In an effort to cope with the increasing demand of services on the Defense Satellite Communications System (DSCS) and more stringent ECCM (electronic counter-countermeasures) requirements, the performance limitations on the DSCS III Receive Multiple Beam Antenna (RMBA) imposed by random and systematic perturbations have been addressed. The concept of VPSFT (variable phase shifter fine tuning) closed-loop control has been investigated thoroughly, first by simulation and then by antenna-range tests and on-orbit measurement. As a result, its feasibility and utility have been firmly established. The VPSFT closed-loop scheme represents a technical breakthrough for extending the RMBA performance beyond its original design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effect of Surface Energy on Freezing Temperature of Water (2016)

Previous studies have found that superhydrophobic surfaces are effective in delaying freezing of water droplets. However, the freezing process of water droplets on superhydrophobic surfaces depends on factors such as droplet size, surface area, roughness, and cooling rate. The role of surface energy, independent of any other parameters, in delaying freezing of water is not understood. Here, we have used infrared-visible sum frequency generation spectroscopy (SFG) to study the freezing of water next to solid substrates with water contact angles varying from 5° to 110°. We find that the freezing temperature of water decreases with increasing surface hydrophobicity only when the sample volume is small (∼10 μL). For a larger volume of water (∼300 μL), the freezing temperature is independent of surface energy. For water next to the surfaces with contact angle ≥54°, we observe a strong SFG peak associated with highly coordinated water. This research sheds new light on understanding the key factors in designing new anti-icing coatings.
Absence of VOD in paediatric thalassaemic HSCT recipients using defibrotide prophylaxis and intravenous Busulphan (2009)

Hepatic veno-occlusive disease (VOD) is a common complication of haematopoietic stem cell transplantation (HSCT), with reported incidences of 5-40% in children. Recently, defibrotide (DF) has been successfully used as prophylaxis and treatment of VOD. This study reports data on 63 human leucocyte antigen-matched HSCT performed in 57 children affected by beta thalassemia at very high risk for developing VOD (liver fibrosis, iron overload, hepatitis C virus infections, busulphan-based conditioning, methotraexate + ciclosporine). All patients received a busulphan-based conditioning regimen, either orally (four HSCT) or intravenously (59 HSCT). All patients received oral DF (40 mg/kg per day, final dose) as VOD prophylaxis from median day -9 to median day +29. In order to overcome the lack of oral paediatric formulations, a galenic formulation was administered. DF was well tolerated. Only one patient fulfilled Seattle Criteria for VOD diagnosis. This patient had discontinued DF 6 d prior to VOD onset, due to high risk of haemorrhage. We concluded that oral defibrotide prophylaxis and i.v. busulphan safely abated VOD incidence in high-risk patients who had undergone HSCT. A galenic preparation of oral DF also permits this treatment in low-weight patients. Costs of DF prophylaxis are acceptable considering the reduced incidence of VOD.
