A practical approach to diagnosing and treating infertility by the generalist in obstetrics and gynecology (2015)

Because the generalist will not be tempted to suggest therapies, e.g., IVF-ET because this effective therapy is the best option for the financial success of the REI, but at the expense of financial depletion of the patient, there is plenty of room for generalists taking over as the first line physicians for infertility rather than just a referral service. Reproductive endocrinologists/infertility will almost invariably perform IUI each month even if not doing IVF which is also profitable to the REI, but costly in time and money to the patient. In contrast, the generalist, aimed with the knowledge that IUI does not improve pregnancy rates if the post-coital test is normal, will save the patient and/or the insurance money if the woman conceives. Obviously certain circumstances, e.g., bilateral blocked fallopian tubes or very severe oligoasthenozoospermia (but not teratozoospermia) will prompt an immediate referral to an REI.
Somatosensory evoked potentials, cerebral blood flow and metabolism following cerebral missile trauma in monkeys. (1977)

Somato sensory evoked potentials (SEP), cerebral blood flow and cerebral metabolism were studied in seven rhesus monkeys before and after a right occipito-frontal missile injury with an air rifle. The sensory evoked potential was present shortly after injury though markedly altered in shape. There was a very close correlation (r2 equal to 0.83) between SEP and cerebral blood flow on the uninjured side five minutes after injury. On the injured side, this was also noted but the amplitude of the SEP was much smaller, perhaps due to direct injury. If the flow in either hemisphere fell below 15-20 mls/100 gm/min, the evoked response disappeared, but in several animals a subsequent increase in flow was associated with a return of electrical activity. There was no correlation with cerebral perfusion pressure or cerebral metabolic rates for oxygen or lactate production, though it is likely that this is not due to physiological reasons but rather methodological. It might be inferred from these results that adequate flow is vital for the preservation and return of electrical activity following brain injury.
Delaying histone deacetylase response to injury accelerates conversion into repair Schwann cells and nerve regeneration (2017)

The peripheral nervous system (PNS) regenerates after injury. However, regeneration is often compromised in the case of large lesions, and the speed of axon reconnection to their target is critical for successful functional recovery. After injury, mature Schwann cells (SCs) convert into repair cells that foster axonal regrowth, and redifferentiate to rebuild myelin. These processes require the regulation of several transcription factors, but the driving mechanisms remain partially understood. Here we identify an early response to nerve injury controlled by histone deacetylase 2 (HDAC2), which coordinates the action of other chromatin-remodelling enzymes to induce the upregulation of Oct6, a key transcription factor for SC development. Inactivating this mechanism using mouse genetics allows earlier conversion into repair cells and leads to faster axonal regrowth, but impairs remyelination. Consistently, short-term HDAC1/2 inhibitor treatment early after lesion accelerates functional recovery and enhances regeneration, thereby identifying a new therapeutic strategy to improve PNS regeneration after lesion.

Computer-Aided Diagnosis of Acute Lymphoblastic Leukaemia (2018)

Leukaemia is a form of blood cancer which affects the white blood cells and damages the bone marrow. Usually complete blood count (CBC) and bone marrow aspiration are used to diagnose the acute lymphoblastic leukaemia. It can be a fatal disease if not diagnosed at the earlier stage. In practice, manual microscopic evaluation of stained sample slide is used for diagnosis of leukaemia. But manual diagnostic methods are time-consuming, less accurate, and prone to errors due to various human factors like stress, fatigue, and so forth. Therefore, different automated systems have been proposed to wrestle the glitches in the manual diagnostic methods. In recent past, some computer-aided leukaemia diagnosis methods are presented. These automated systems are fast, reliable, and accurate as compared to manual diagnosis methods. This paper presents review of computer-aided diagnosis systems regarding their methodologies that include enhancement, segmentation, feature extraction, classification, and accuracy.
Clinical manifestations and impact on daily life of allergy to polyethylene glycol (PEG) in ten patients (2021)

The clinical manifestations of PEG allergy are often dramatic. Improved awareness about the clinical presentation and common culprits, clear product labelling and a standardized nomenclature is needed to ensure the timely diagnosis of PEG allergy to prevent repeated anaphylactic reactions with severe impact on patients' lives.
Integrating ZigBee-based mesh network with embedded passive and active RFID for production management automation (2013)

Increasing sales and demand in the electronics industry involve increases in products and output in production lines. This phenomenon suggests complexity as well as lack of control and poor management of production lines. An unmanageable system in the production line leads to problems in production management. An example of this problem relates to the quantity of output in each production line. Output level is an important consideration in production management for monitoring, controlling, and updating information on the condition and the location of the production floor. This study introduces several engineering management system for real-time monitoring, controlling, and updating information by integrating radio frequency identification (RFID) systems with wireless network. In this study, a combination of passive and active RFIDs with an embedded controller board was designed according to specific functions and operation modules under Wireless Sensor Network (WSN) platform. Ease in implementing the system provides companies an ideal solution for fast and convenient monitoring of manufacturing and distribution activities. These integrated modules are used in automated, wireless-readable, sensory-based identification techniques and Web-based monitoring, thereby enhancing reliability and providing more functionalities.

Fe-TiO 2 supported on spherical activated carbon (Fe-TiO 2 /SAC) with different Fe contents was prepared by heat treatment process after ion exchange method. The prepared Fe-TiO 2 /SAC was characterized by SEM, EDS, and BET. Batch experiments for photocatalytic degradation of humic acid by Fe-TiO 2 /SAC were carried out in the fluidized bed photoreactor. It was found that 0 wt% Fe-TiO 2 /SAC had high photocatalytic activity in the wavelength range of 100 ~ 280 nm. However, Fe-TiO 2 /SAC with Fe contents of 0.4, 0.6, and 0.8 wt% exhibited higher photocatalytic activity than 0 wt% Fe-TiO 2 /SAC in the wavelength range of 315 ~ 400 nm compared to that of 100 ~ 280 nm. The optimum Fe content was 0.6 wt% for maximum photocatalytic degradation of humic acid. Moreover, Fe-TiO 2 /SAC does not require an additional process step for separation of photocatalyst from treated water after photocatalysis.
Design and analysis of a linear type electromagnetic stirrer (2004)

Electromagnetic stirring (EMS) of metallic alloys is mainly used to refine the grain structure of castings. This technique results in increased homogeneity of the cast alloys. In this paper a design oriented approach to a linear electromagnetic stirrer is presented. A mathematical model of such a stirrer is proposed to obtain electromagnetic field solutions. The field solutions so obtained are compared with those obtained from the finite-element model. The influences of excitation frequency and current on the induced current density and axial force and their variation with radius have been investigated. Experimental results obtained from a prototype are presented.
EQVMP: Energy-efficient and QoS-aware virtual machine placement for software defined datacenter networks (2014)

To provide effective and reliable services, cloud datacenters need parallel computing and virtualization techniques. This work presents an improved virtual machine (VM) placement mechanism, called Energy efficiency and Quality of Service (QoS) aware VM Placement (EQVMP) to overcome the problem of unbalanced traffic load in switching on and off VMs for the purpose of energy saving. EQVMP combines three key techniques: (1) hop reduction, (2) energy saving and (3) load balancing. Hop reduction can regroup VMs to lower the traffic load among them. Energy saving techniques aim at choosing the appropriate servers. The proposed load balancing updates VM placement periodically. Our experimental results show that the proposed scheme can lower energy consumption and maintain QoS. We propose an evaluation score [1] to assess VM placement in terms of energy, delay and throughput. Comparing to other existing placement policies, our proposed mechanism can enhance system throughput by 25% and can have better evaluation score.
Confocal scanning optical microscopy and its applications for biological specimens (1989)

ABSTRACT Confocal scanning optical microscopy (CSOM) is a new optical microscopic technique, which offers significant advantages over conventional microscopy. In laser scanning optical microscopy (SOM), the specimen is scanned by a diffractionlimited spot of laser light, and light transmitted or reflected by the in-focus illuminated volume element (voxel) of the specimen, or the fluorescence emission excited within it by the incident light, is focused onto a photodetector. As the illuminating spot is scanned over the specimen, the electrical output from this detector is displayed at the appropriate spatial position on a TV monitor, thus building up a two-dimensional image. In the confocal mode, an aperture, usually slightly smaller in diameter than the Airy disc image, is positioned in the image plane in front of the detector, at a position confocal with the in-focus voxel. Light emanating from this in-focus voxel thus passes through the aperture to the detector, while that from any region above or below the focal plane is defocused at the aperture plane and is thus largely prevented from reaching the detector, contributing essentially nothing to the confocal image. It is this ability to reduce out-of-focus blur, and thus permit accurate non-invasive optical sectioning, that makes confocal scanning microscopy so well suited for the imaging and three-dimensional tomography of stained biological specimens. In this review, I explain the principles of scanning optical microscopy and blur-free confocal imaging, discuss the various imaging modes of confocal microscopy, and illustrate some of its early applications.
Experimental suture of the peripheral nerves with "fibrin glue". (1980)

An experiment on rats is presented, concerned with a technique for suturing peripheral nerves by means of "human fibrin glue". The sutures were performed by three different methods: (1) the traditional technique; (2) using a special grooved Vitallium plate (presented by the authors in a previous paper) by means of which all sutures can be dispensed with, and which facilitates more rapid and complete regeneration of the nerve; (3) with "fibrin glue", used on its own or together with the special plate. On comparing the three methods it was found that fibrin glue achieves better approximation of the nerve ends and thus leads to more rapid and more complete regeneration of the peripheral nerve fibres. Combined use with the plate is preferred where there is a minimal loss of nerve substance.
ULTRASTRUCTURE OF HUMAN LEUKOCYTES AFTER SIMULTANEOUS FIXATION WITH GLUTARALDEHYDE AND OSMIUM TETROXIDE AND "POSTFIXATION" IN URANYL ACETATE (1968)

Human leukocytes in suspension or in monolayer cultures have been processed for electron microscopy by fixation in a freshly made cold mixture of glutaraldehyde and osmium tetroxide and by "postfixation" in uranyl acetate. Simultaneous exposure to glutaraldehyde and osmium tetroxide eliminates many of the shortcomings seen when either of these agents is used alone as the initial fixative. Specimens are processed to the stage of dehydration as single cell suspensions or as very small clumps to assure rapid penetration of fixatives and efficient washing. The technique is rapid and reproducible. Electron micrographs presented in this report illustrate the ultrastructural features of human white cells prepared by this method.

The control of developmental phase transitions in plants (2011)

Plant development progresses through distinct phases: vegetative growth, followed by a reproductive phase and eventually seed set and senescence. The transitions between these phases are controlled by distinct genetic circuits that integrate endogenous and environmental cues. In recent years, however, it has become evident that the genetic networks that underlie these phase transitions share some common factors. Here, we review recent advances in the field of plant phase transitions, highlighting the role of two microRNAs - miR156 and miR172 - and their respective targets during these transitions. In addition, we discuss the evolutionary conservation of the functions of these miRNAs in regulating the control of plant developmental phase transitions.

Machine learning for streaming data (2019)

Incremental learning, online learning, and data stream learning are terms commonly associated with learning algorithms that update their models given a continuous influx of data without performing multiple passes over data. Several works have been devoted to this area, either directly or indirectly as characteristics of big data processing, i.e., Velocity and Volume. Given the current industry needs, there are many challenges to be addressed before existing methods can be efficiently applied to real-world problems. In this work, we focus on elucidating the connections among the current stateof- the-art on related fields; and clarifying open challenges in both academia and industry. We treat with special care topics that were not thoroughly investigated in past position and survey papers. This work aims to evoke discussion and elucidate the current research opportunities, highlighting the relationship of different subareas and suggesting courses of action when possible.
Environmentally friendly processes in the manufacture of Saturn solar cells (2003)

The current metallisation process for the manufacture of laser grooved, buried grid solar cells is based on electroless chemical plating. An electrolytic copper plating process is described that has the advantages of increased bath lifetime; shorter processing time; improved material usage; reduced over-plating; superior quality of the copper deposited and reduced effluent treatment costs. This paper describes work using a prototype electro-plating bath. This paper also describes an investigation of the use of cyanide-free solutions for coating the plated copper deposit on the solar cell. A number of electroless silver and tin coatings offer environment-friendly alternatives to the current silver cyanide process.
Effects of attenuation and scattering on AVO measurements (1998)

Abstract The trends and variance in amplitude variation with offset (AVO) observations caused by near-surface structure, attenuation, and scattering are numerically synthesized by pseudospectral viscoelastic 2-D modeling. Near-surface structure produces amplitude focusing and defocusing that significantly distort AVO observations in offset windows at a scale comparable to that of the lateral variations in the structure. Attenuation and scattering decrease absolute amplitudes at all offsets. Scattering and wave interference increase the variance associated with AVO measurements. Depending on the relative influence of intrinsic attenuation, apparent attenuation associated with scattering, and geometrical focusing, a normalized AVO response can increase or decrease with offset (relative to that for the associated elastic, nonscattering, 1-D solution), and so mimic the behavior predicted as a function of contrasts in density, velocity, porosity or Poisson's ratio. If only relative (normalized) amplitudes are available, it is difficult to distinguish between effects of parameters whose main contributions are to absolute amplitude; for example, a trend of decreasing amplitude (relative to that for an elastic flat-layered model) produced by intrinsic attenuation may be counteracted by focusing/scattering or anisotropic effects over wide aperture ranges. Diagnostic information on AVO effects of scattering and attenuation is lost when the noise level is sufficiently high. Interpretations of AVO observations based on homogeneous layered elastic models must therefore be used with caution as they are, in general, nonunique. Lateral variations in AVO parameters are the key to detecting hydrocarbons, so lateral changes in AVO produced by lateral changes in the overburden properties have potential for being misinterpreted, especially if the recording aperture is small.
Sleep Apnea, Hypersomnolence, and Upper Airway Obstruction Secondary to Adenotonsillar Enlargement (1977)

• The authors examined four children with substantial adenotonsillar enlargement that caused intermittent severe upper airway obstructive episodes, documented by all-night polygraphic monitoring of sleep and respirations. Previously unreported complications of severe adenotonsillar enlargement that were demonstrated included prolonged obstructive apneic episodes and disturbed sleep patterns. The children also exhibited daytime hypersomnolence. Polygraphic sleep studies after adenotonsillectomy confirmed improved sleep patterns and relief of the obstructive episodes. None of our patients had developed pulmonary hypertension, cor pulmonale, or other reported complications of prolonged upper airway obstruction, all of which may have been averted by early diagnosis and treatment.
Varicocele in Children and Adolescents: An Investigation of the Incidence Among Danish School Children (1971)

The incidence of varicocele in an unselected material consisting of 1072 Danish school boys aged 6–19 years was investigated. No cases of varicocele were encountered in 188 boys, aged 6–9 years, while the incidence in the 837 examined boys, aged 10–19 years, was 16.2%. This showed a steadily increasing incidence from 5.7% in the 10-year-old group to 19.3% at the age of 14 years. The incidence of “genuine” clinical varicocele showed an increase from 1.9% in 10-year-olds to 10.6% in 14-year-olds. All of the varicoceles were found in the left half of the scrotum. The development of puberty was more advanced in the boys with varicocele than in the control material. The boys with varicocele were taller than those without. These two observations are presumed to be of significance for the development of varicocele. The figures for the incidence of varicocele from the literature, compared with the author's own findings, suggest that there is a difference in the incidence of varicocele in fertile and infertile males. Furthermore it appears probable that, in some cases, varicocele plays a part in spermatogenesis and fertility. In cases such as these, high ligation of the internal spermatic vein appears to be an effective form of treatment of the varicocele. This procedure does not damage the testicle and may result in normalisation of spermatogenesis and increased fertility.
Classification of EMG signals through wavelet analysis and neural networks for controlling an active hand prosthesis (2007)

In order to increase the effectiveness of active hand prostheses we intend to exploit electromyographic (EMG) signals more than in the usual application for controlling one degree of freedom (gripper open or closed). Among all the numerous muscles that move the fingers, we chose only the ones in the forearm, to have a simple way to position only two electrodes. We analyze the EMG signals coming from two different subjects using a novel integration of ANN and wavelet. We show how to discriminate between more movements, five in this study, using our new classifier. Results show how the methodology we adopted allows us to obtain good accuracy in classifying the hand postures, and opens the way to more functional hand prostheses.
