Abstract:
Allelic exclusion is established in development through a feedback mechanism in which the assembled immunoglobulin (Ig) suppresses further V(D)J rearrangement. But Ig expression sometimes fails to prevent further rearrangement. In autoantibody transgenic mice, reactivity of immature B cells with autoantigen can induce receptor editing, in which allelic exclusion is transiently prevented or reversed through nested light chain gene rearrangement, often resulting in altered B cell receptor specificity. To determine the extent of receptor editing in a normal, non-Ig transgenic immune system, we took advantage of the fact that λ light chain genes usually rearrange after κ genes. This allowed us to analyze κ loci in IgMλ+ cells to determine how frequently in-frame κ genes fail to suppress λ gene rearrangements. To do this, we analyzed recombined VκJκ genes inactivated by subsequent recombining sequence (RS) rearrangement. RS rearrangements delete portions of the κ locus by a V(D)J recombinase-dependent mechanism, suggesting that they play a role in receptor editing. We show that RS recombination is frequently induced by, and inactivates, functionally rearranged κ loci, as nearly half (47%) of the RS-inactivated VκJκ joins were in-frame. These findings suggest that receptor editing occurs at a surprisingly high frequency in normal B cells.

Abstract:
Cryptochromes (cry) sont des flavoprotéines absorbant la lumière bleue conservées qui ont été liées à perception de stimuli électromagnétiques dans de nombreux organismes. Nous avons principalement étudié le mécanisme d'interaction entre les champs magnétiques (MF) et cry dans le cadre de la théorie des paires de radicaux. Nous avons étudié la réponse d'Arabidopsis cry-1 in vivo à MF. Les activités biologiques du cry ont été renforcées par MF. Les effets des MF ont pu être observés même si MF était donné exclusivement pendant les intervalles d'obscurité entre expositions à la lumière. Cette découverte a indiqué que l'étape de réaction magnétiquement sensible dans photocycle du cry doit se produire pendant la réoxydation des flavines. De plus, nous avons également utilisé la fréquence (RF) stimulée par cry-Arabidopsis comme outils de diagnostic pour confirmer l'hypothèse de la paire de radicaux. Dans l'étude, nous avons trouvé un effet perturbateur des RF sur l'activité du cryptochrome. Notre découverte pourrait confirmer l'apparition du mécanisme de la paire de radicaux et l'implication du cry pour la magnétoréception. De plus, nous avons également montré un effet perturbateur de la condition MF statique de bas niveau (LLF) où les champs magnétiques externes étaient presque éliminés. Le résultat de cette condition était cohérent avec l'effet de l'exposition aux RF. En outre, nous avons également signalé que LLF pourrait augmenter l'expression de certains gènes induits par le PEMF dans dans les les cellules humaines. Cette découverte pourrait fournir des preuves à l'appui de l'effet des champs électriques magnétiques et non induits sur la physiologie humaine
Cryptochromes are highly conserved blue-light-absorbing flavoproteins that have been linked to the perception of electromagnetic stimuli in numerous organisms. We mainly studied the mechanism for the interaction between magnetic fields and cryptochromes in the context of the radical-pair theory. We investigated the response of Arabidopsis cryptochrome-1 in vivo to a static magnetic field. The biological activities of cryptochrome were enhanced by the magnetic field. Interestingly, the effects of the magnetic fields could be observed even the magnetic field was given exclusively during dark intervals between light exposures. This finding indicated that the magnetically sensitive reaction step in the cryptochrome photocycle must occur during flavin reoxidation. Moreover, we also used frequency (RF) stimulated to Arabidopsis cryptochrome as the diagnostic tools to confirm the radical-pair hypothesis. In the study, we found a disruptive effect of RF on the activity of cryptochrome. Our findings could confirm the occurrence of the radical-pair mechanism and the involvement of cryptochrome for magnetoreception. Additionally, we also showed a disruptive effect of the low-level static magnetic field (LLF) condition where the external magnetic fields were almost eliminated. The result of this condition was consistent with the effect of RF exposure. Furthermore, we also reported that LLF could increase the expression of some PEMF-induced genes in human cells. This finding could provide the evidence to support the effect of magnetic, not induced electric fields in human physiology

Abstract:
Psoriatic disease is a multisystem disorder that affects skin and nails. Besides arthritis and spondylitis, involvement of other organ systems occurs in a significant proportion of patients. Within these extra-articular, extra-skin manifestations, eye and gut disease occupy an important place since they are linked in a bi-directional way: eye inflammation and bowel disease occur more frequently in patients with psoriasis and psoriatic arthritis, but there is also an increased prevalence of psoriasis in patients with uveitis or inflammatory bowel disease. In this chapter, we will focus primarily on spondyloarthritis concept-related extra-articular, extra-skin manifestations, such as uveitis, Crohn’s disease, and ulcerative colitis: prevalence, clinical presentation, and therapeutic consequences are discussed.

Abstract:
Acute deep vein thrombosis (DVT) occurs in approximately 300,000 people per year in the United States. Iliocaval thrombosis is most commonly related to the progression of lower extremity DVT. Inferior vena cava (IVC) thrombosis occurs in approximately 4–15% of patients with acute DVT. Vena cava thrombosis is frequently associated with neoplastic disease. Foreign body placement such as an IVC filter or a venous catheter is a frequently reported cause of iliocaval thrombosis. External compression due to right common iliac artery mass effect (May–Thurner syndrome), tumor, lymphadenopathy, or aortic aneurysm are also commonly seen. This chapter discusses the interventional measures to manage acute iliocaval thrombosis.

Abstract:
Craniosynostosis is the fusion of one or more cranial sutures; such fusion occurs due to multiple factors and typically occurs in utero. Depending on the sutures involved, the infant can have significant abnormalities in skull shape. The structural abnormality is corrected surgically, frequently after a series of operations starting from infancy and occurring even late in childhood, depending on the sutures that are fused. During these surgeries, an infant can lose substantial volumes of blood, increasing the risk of hypovolemia and venous air embolism. It is imperative for the pediatric anesthesiologist to employ various modalities to minimize blood loss and also recognize clinical signs indicating the need for transfusion.

Abstract:
Pasteurellosis is a zoonosis that occurs worldwide, caused by bacteria of the genus Pasteurella, and other related organisms. Pasteurellosis reported in humans is most frequently caused by the species Pasteurella multocida. In humans, cutaneous infection is most common, but more severe outcomes have been reported, particularly in those with underlying chronic disease. Infection in animals is usually subclinical, but may give rise to a range of clinical symptoms, depending on the host species. Disease in animals usually occurs as a consequence of stress such as overcrowding, chilling, transportation, or as a result of a concurrent infection. In animals, pasteurellosis is known as: shipping fever or pneumonia, transport or transit fever, stockyard pneumonia, bovine pneumonic pasteurellosis, haemorrhagic septicaemia, or avian, bird or fowl cholera. The pasteurella bacterium is commonly present in the mouth and gastrointestinal tract of a wide range of mammals. Transmission to humans occurs after bites, scratches, or licks from infected animals, most frequently from dogs or cats, although infection has been associated with other animals including: cows, pigs, hamsters and rabbits. However, not all patients report a history of direct animal contact. Infection may be prevented through the avoidance of animal bites and the prompt hygienic care of wounds. Health professionals should be aware of the risk of pasterurellosis in immunocompromised patients exposed to companion animals.

Full text
Abstract:
A spinal epidural abscess is an infection that resides in the epidural space of the spinal canal, and most commonly occurs from hematogenous seeding or direct extension from adjacent structures. Normal skin flora such as Staphylococcus and Streptococcus spp are the most common organisms to cause an epidural abscess, typically when host immunity is compromised or due to barrier disruption. The clinical presentation is heterogeneous, but often will progress over time to spinal cord compression. Intracranial epidural abscess and subdural empyema occur within the skull and are frequently spread via direct extension of infections from contiguous structures or as complications from neurosurgical procedures. Prompt diagnosis and treatment is essential for improving morbidity and mortality.

Abstract:
Patients frequently require airway management during rapid response team (RRT) activations. Airway management during RRT activations frequently occurs in locations that are not well equipped or prepared to perform airway procedures. Therefore, it is important that RRTs arrive with the proper equipment and medications to safely secure the airway whenever necessary. An “airway bag” that is stocked by a hospital’s central supply department and carried by RRTs ensures the availability of functioning equipment and helps to standardize the process of airway management during RRT activation. In this chapter, we will review recommendations for equipment required in emergency airway management, including portable routine and difficult airway equipment and medications.

The appearances of this theme in various keys suggest an overarching harmonic structure based on the whole-tone scale, giving way frequently to an opposition between the keys of A and E-flat. A whole-tone scale plus one other note serves as an importance source-chord for the entire sonata.

Full text
Abstract:
Third-party punishment occurs among insect species, cleaner fish, and non-human primates. This suggests that organisms do not need a sophisticated sense of morality to be punitive. Why, then, did humans evolve a moral punishment instinct? The main proposition of this chapter is that people evolved a sense of morality as a consequence of their punishment instincts. In ancestral groups of hunter-gatherers, punishment had genetic consequences, as it frequently meant death, exclusion, or unattractively low social standing. Punishment therefore has put social selection pressures on our ancestors to evolve intrinsic motivations to pursue the interests of the group. Furthermore, whereas punishment is frequently portrayed as costly, the chapter illuminates that punishers also reap important benefits: punishment can be a form of costly signaling, emphasizing punishers’ power, making them attractive mates.

Abstract:
Small vessel vasculitis is vasculitis affecting predominately small intraparenchymal arteries, arterioles, capillaries, and venules. There are two main types: antineutrophil cytoplasmic antibody associated and immune complex mediated. The ANCA associated vasculitides are discussed in chapter 19.3 IgA vasculitis (IgAV) was formerly known as Henoch Schönlein purpura. The revised nomenclature reflects the importance of IgA vasculitis in pathogenesis. The Chapel Hill Consensus Conference defined IgA vasculitis as ‘vasculitis with IgA1-dominant immune deposits, affecting small vessels (predominantly capillaries, venules, or arterioles)’. IgA vasculitis often involves skin and gut, and frequently causes arthritis. Glomerulonephritis indistinguishable from IgA nephropathy may occur. Its aetiology is unknown, but it frequently occurs after an infection several days to weeks before. The most frequently isolated organism is beta-haemolytic streptococcus. Drugs such as a penicillin, ampicillin, erythromycin, and non-steroidal anti-inflammatory drugs have been reported as precipitating agents. There is an association with HLA-DRB1*01 in Caucasians and there appears to be a familial association.

This case illustrates acute respiratory distress in pediatric patient populations. More specifically, it highlights signs of upper airway obstruction, including stridor. This type of presentation most frequently occurs with croup, also known as laryngotracheobronchitis, but can also occur in other pathologic conditions, which are briefly discussed. Croup is a viral infection that causes upper respiratory tract symptoms, including a harsh “seal-like” barking cough, secondary to mucosal edema in the upper airway. Significant swelling can cause respiratory distress with development of stridor, prompting treatment with nebulized epinephrine. In addition, steroid medication is often administered for longer term symptom control. Most children recover well in a relatively short time period.

The focus of the discussion is on the fiqh treatment of mubah as a value category, including its sources, varieties, and how it is understood by the leading schools of Islamic law. Of the three Arabic words that appear in this heading, halal and its derivatives occur more frequently in the Qur’an and hadith, whereas the fiqh literature is more inclined to employ mubah and ja’iz.

Abstract:
This chapter provides an overview of the construct of attachment security and describes the threat to this security that may arise in response to the diagnosis or progression of advanced disease. The heightened mortality salience that occurs in this context activates the attachment system, and increased dependency and caregiving needs frequently require an adjustment or renegotiation of attachment security. Attachment security protects from death anxiety and other forms of distress, and so the renegotiation of attachment relationships is often an urgent task that is needed to maintain or restore emotional equilibrium. This chapter explains the central role of attachment security in the Managing Cancer and Living Meaningfully (CALM) intervention, in which the therapeutic relationship can provide a secure base to process distressing thoughts and feelings and to face the challenges that inevitably occur.

Abstract:
Atherosclerosis frequently occurs at the carotid bifurcation and plaque rupture at this site is one of the leading causes of stroke. Over 50% of these strokes occur in asymptomatic patients and thus better indicators of the disease need to be developed. Finite element studies of arterial wall segments have provided key information on the biomechanics of arteries, from prediction of atherosclerotic plaque rupture [1] to the effectiveness of stents [2]. Most studies however have focused on simple straight arterial segments and few on complex geometries such as bifurcations or aneurysms. Studies which have addressed the carotid bifurcation have been based on either idealised geometries [3] or on a single patient specific geometry often generated from cadaveric material [4].

Abstract:
In the process of compressor operation, the vibration of the pipeline occurs frequently and has a strong impact on safety. The in-field vibration measurement is carried out on the pipeline of a centrifugal compressor, and the vibration waveform and spectrum characteristics are obtained. Numerical studies are conducted to investigate the relationship between the natural frequency of the pipeline and the fluid excitation frequencies. These numerical results are verified by comparison with the field measurement values, which shows that the method can be useful for engineering applications. Some preliminary conclusions are drawn from the results of the field measurement and the numerical simulation. Pressure fluctuations not only occur in the measuring pipeline, but also spread to the pipeline in the distance. The sensitive frequencies of the pipeline vibration are determined, and the fundamental causes of the vibration revealed. Accordingly, the pipeline structure can be improved, and the method of solving the fluid excitation is discussed to avoid the damage caused by the pipeline vibration and ensure the safety of the equipment and the pipeline.

Abstract:
The anatomy and biomechanics of the intervertebral motion segments is complex, and the development of degenerative motion segment disorders, which occur frequently, is poorly understood. When disc degeneration occurs at one level, whether treated or not, degeneration frequently develops at mobile segments above or below the degenerated or treated segments. After surgical treatment the process is referred to adjacent segment disc disease (ASDD), and the condition clinically called transition syndrome. We do not know at this time if the ASDD is caused by the neighboring degenerated disc or if they represent the natural progression of the lumbar degenerative processes. The development of ASDD is clinically problematic because it can cause pain and necessitate further surgical intervention. The development and severity of ASDD in disc degeneration is broadly believed to depend on a number of variables such as the severity of degeneration, the number of levels that are degenerated and the location of the degenerative disc. Thus it is important to understand how ASDD develops and progresses and how different variables that cause ASDD compare with reference to normal disc biomechanics. It is proposed to address this clinically relevant problem using poroelastic finite element models.

Abstract:
In this paper, we report a novel hybrid energy micro-harvester. The harvester utilizes ferromagnetic materials combined with piezoelectric cantilever beams to harvest the energy from a thermal, mechanical, and magnetic energy sources and subsequently convert the energy to an electrical output. In addition to energy-harvesting, the harvester utilizes a non-contact approach in its structure to avoid the wear problem which frequently occurs in conventional structural-contact approaches.

Abstract:
Rising road densities, vehicle speeds limits and traffic volumes, combined with recent growth in the population density of various deer species, have increased the risk of DVCs across the world, causing a great deal of animal suffering, traffic safety problems and socio-economic costs. Object of this investigation was to find out collisions trend with roe deer (Capreolus capreolus) in Lithuania. The aim of our study was to determine where in Lithuania accidents occure more frequently and evaluate these accidents in time. In 2013–2017 number of AVCs in Lithuania was recorded more then 12 011 times, over half of 7155 occur with roe deer. The temporality of accidents was studied under three scales – daily, weekly and seasonal. Daily peaks start at 7:00 (8.75%), 8:00 (6.08%). Evening peaks, start at 17:00 (7.71%), other at 22:00 (10.64%) hours. Week collisions with roe deer increase on Friday 14.9%. The risk of collision with roe deer varies over the year – the majority of crashes occur in May 14.7% and November 10.7%. In spatial study localization of collision data with ArcGIS 10.3. It was found that road surrounding landscape dominated by agricultural land collisions occurred at a maximum of 29.77%. 19.10% collisions were recorded in the forest area. In built-up areas 11.85%. Analysis of these trends allow to simulate and predict when and where the highest risk of DVCs occurs. In conclusion, this could give valuable information and constitute a manageable tool for the road managers, planners, scientist, wildlife conservationist who are interested in these type of accidents in regions of Lithuania.

Abstract:
Abstract NCF (Non Conductivity Film) is a material used for under-fill purpose in the TSV (Through Silicon Via) process, and is a key material for ensuring TSV 3D Package (PKG) reliability. Among the types of defects generated by the NCF, the most typical type is delamination. Particularly in NCF delamination frequently occurs during reliability test, we analyzed chemical state change of NCF according to reliability test step/condition by utilizing FTIR and TMA. Through these studies, we clarify the cause of Delamination.

Abstract:
Glaucoma, a chronic optic neuropathy, is the second most common cause of blindness, affecting 67 million people worldwide. The damage in glaucoma occurs at the optic nerve head (ONH), where the axons of the retinal ganglion cells leave the eye posteriorly. Glaucoma is frequently associated with elevated intraocular pressure (IOP), and visual field loss can be prevented by significant lowering of IOP. Hence, the role of pressure in glaucoma is important. Unfortunately, the mechanism by which pressure leads to vision loss in glaucoma is very poorly understood.

Abstract:
The media plays a critical role in terms of shaping public perceptions, but they have a task on their hands in terms of effectively communicating a subject as vast and complex as climate change. India is among the countries most affected and yet reporting on the subject has been episodic, with peaks around the time of climate summits and in the immediate aftermath of disasters such as cyclones, heatwaves and extreme rainfall events. Through a media review, undertaken as part of the Earth Journalism Network Asia-Pacific Media Grant, we sought to understand patterns of representation in news coverage about urban drought and extreme weather events – predicted to occur more frequently and intensely in a warming world. This report details the methodology we followed, our findings and analyses them in the context of other work done as part of the evolving field of climate change communication.

Full text
Abstract:
Ice fog events, which occur during the Arctic winter, result in greatly decreased visibility and can lead to an increase of ice on roadways, aircraft, and airfields. The Fairbanks area is known for ice fog conditions, and previous studies have shown these events to be associated with moisture released from local power generation. Despite the identified originating mechanism of ice fog, there remains a need to quantify the environmental conditions controlling its origination, intensity, and spatial extent. This investigation focused on developing innovative methods of identifying and characterizing the environmental conditions that lead to ice fog formation near Fort Wainwright, Alaska. Preliminary data collected from December 2019 to March 2020 suggest that ice fog events occurred with temperatures below −34°C, up to 74% of the time ice fog emanated from the power generation facility, and at least 95% of ice particles during ice fog events were solid droxtals with diameters ranging from 7 to 50 μm. This report documents the need for frequent and detailed observations of the meteorological conditions in combination with photographic and ice particle observations. Datasets from these observations capture the environmental complexity and the impacts from energy generation in extremely cold weather conditions.

Abstract:
To promote active transportation modes (such as bike ride and walking), and to create safer communities for easier access to transit, it is essential to provide consolidated data-driven transportation information to the public. The relevant and timely information from data facilitates the improvement of decision-making processes for the establishment of public policy and urban planning for sustainable growth, and for promoting public health in the region. For the characterization of the spatial variation of transportation-emitted air pollution in the Fresno/Clovis neighborhood in California, various species of particulate matters emitted from traffic sources were measured using real-time monitors and GPS loggers at over 100 neighborhood walking routes within 58 census tracts from the previous research, Children’s Health to Air Pollution Study - San Joaquin Valley (CHAPS-SJV). Roadside air pollution data show that PM2.5, black carbon, and PAHs were significantly elevated in the neighborhood walking air samples compared to indoor air or the ambient monitoring station in the Central Fresno area due to the immediate source proximity. The simultaneous parallel measurements in two neighborhoods which are distinctively different areas (High diesel High poverty vs. Low diesel Low poverty) showed that the higher pollution levels were observed when more frequent vehicular activities were occurring around the neighborhoods. Elevated PM2.5 concentrations near the roadways were evident with a high volume of traffic and in regions with more unpaved areas. Neighborhood walking air samples were influenced by immediate roadway traffic conditions, such as encounters with diesel trucks, approaching in close proximity to freeways and/or busy roadways, passing cigarette smokers, and gardening activity. The elevated black carbon concentrations occur near the highway corridors and regions with high diesel traffic and high industry. This project provides consolidated data-driven transportation information to the public including: 1. Transportation-related particle pollution data 2. Spatial analyses of geocoded vehicle emissions 3. Neighborhood characterization for the built environment such as cities, buildings, roads, parks, walkways, etc.

Abstract:
Anorexia nervosa (AN) and autism spectrum disorder (ASD) seem to co-occur more frequently than would be expected by chance.1,2 Yet because most studies investigating the nature of this co-occurrence have used a retrospective design, where the data are prone to recall bias, we don’t know whether the elevation of autistic traits in AN is present from childhood or rather from AN onset.
