Identifying and addressing equivocal trouble in understanding within classroom interaction

Maintaining intersubjectivity is crucial for accomplishing coordinated social action. Although conversational repair is a recognised defence of intersubjectivity and routinely used to address ostensible sources of trouble in social interaction, it is less clear how people address more equivocal trouble. This study uses conversation analysis to examine preschool classroom interaction, focusing on practices used to identify and address such trouble. Repair is found to be a recurrent frontline practice for addressing equivocal trouble, occasioning space for further information that might enable identifying a specific trouble source. Where further information is forthcoming, a range of strategies are subsequently employed to address the trouble. Where this is not possible or does not succeed, a secondary option is to progress a broader activity-in-progress. This allows for the possibility of another opportunity to identify and address the trouble. Given misunderstandings can jeopardise interactants’ ability to mutually accomplish courses of action, these practices defend intersubjectivity against the threat of equivocal trouble.

Neuro- and immunotoxic effects of fumonisin B1 in cells

Fumonisin B1 (FB1) is a mycotoxin produced by the fungus Fusarium verticillioides, which commonly infects corn and other agricultural products. Fusarium species can also be found in moisture-damaged buildings, and therefore there may also be human exposure to Fusarium mycotoxins, including FB1. FB1 affects the metabolism of sphingolipids by inhibiting the enzyme ceramide synthase. It is neuro-, hepato- and nephrotoxic, and it is classified as possibly carcinogenic to humans. This study aimed to clarify the mechanisms behind FB1-induced neuro- and immunotoxicity. Four neural and glial cell lines of human, rat and mouse origin were exposed to graded doses of FB1 and the effects on the production of reactive oxygen species, lipid peroxidation, intracellular glutathione levels, cell viability and apoptosis were investigated. Furthermore, the effects of FB1, alone or together with lipopolysaccharide (LPS), on the mRNA and protein expression levels of different cytokines and chemokines were studied in human dendritic cells (DC). FB1 induced oxidative stress and cell death in all cell lines studied. Generally, the effects were only seen after prolonged exposure at 10 and 100 µM of FB1. Signs of apoptosis were also seen in all four cell lines. The sensitivities of the cell lines used in this study towards FB1 may be classified as human U-118MG glioblastoma > mouse GT1-7 hypothalamic > rat C6 glioblastoma > human SH-SY5Y neuroblastoma cells. When comparing cell lines of human origin, it can be concluded that glial cells seem to be more sensitive towards FB1 toxicity than those of neural origin. After exposure to FB1, significantly increased levels of the cytokine interferon-γ (IFNγ) were detected in human DC. This observation was further confirmed by FB1-induced levels of the chemokine CXCL9, which is known to be regulated by IFNγ. During co-exposure of DC to both LPS and FB1, significant inhibitions of the LPS-induced levels of the pro-inflammatory cytokines interleukin-6 (IL-6) and IL-1β, and their regulatory chemokines CCL3 and CCL5 were observed. FB1 can thus affect immune responses in DC, and therefore, it is rather likely that it also affects other types of cells participating in the immune defence system. When evaluating the toxicity potential of FB1, it is important to consider the effects on different cell types and cell-cell interactions. The results of this study represent new information, especially about the mechanisms behind FB1-induced oxidative stress, apoptosis and immunotoxicity, as well as the varying sensitivities of different cell types towards FB1.

The standard you walk past is the standard you accept

In his 2013 three-minute speech on unacceptable behaviour in the workplace, Lieutenant General David Morrison makes the above insightful statement. While the context of the speech is the defence force, the meaning of the powerful message holds true for perioperative nursing. Perioperative nurses are part of a profession. Professions Australia, a national organisation of professional associations which aims to advance and promote professionalism for the benefit of the community, provides us with a definition of a profession2 and perioperative nurses meet this definition. Perioperative nurses possess special knowledge and skills grounded in a widely recognised body of discipline knowledge derived from research, education and high-level training. We control and regulate our own boundaries of work. We adhere to ethical and professional standards and values. Specialty professional practice standards define perioperative nurses as a community of professionals — assisting perioperative nurses when advocating for consistency in quality patient care3. It is an imperative for every professional perioperative nurse to model practice underpinned by the ACORN Standards throughout their workplace. Hence, Lieutenant General Morrison’s profound statement is a mantra each perioperative nurse could readily adopt and model in their practice environment...

Induced Resistance: Potential for Control of Postharvest Diseases of Horticultural Crops

Fortunately, plants have developed highly effective mechanisms with which to defend themselves when attacked by potentially disease-causing microorganisms. If not, then they would succumb to the many pathogenic fungi, bacteria, viruses, nematodes and insect pests, and disease would prevail. These natural defence systems of plants can be deliberately activated to provide some protection against the major pathogens responsible for causing severe yield losses in agricultural and horticultural crops. This is the basis of what is known as ‘induced’ or ‘acquired’ disease resistance in plants. Although the phenomenon of induced resistance has been known amongst plant pathologists for over 100 years, its inclusion into pest and disease management programmes has been a relatively recent development, ie. within the last 5 years. This review will discuss very briefly some of the characteristics of the induced resistance phenomenon, outline some of the advantages and limitations to its implementation and provide some examples within a postharvest pathology context. Finally some approaches being investigated by the fruit pathology team at DPI Indooroopilly and collaborators will be outlined.

Matti Laurila : Jääkäriupseeri, suojeluskuntapäällikkö, rintamakomentaja

Matti Laurila (1895 1983) This is a biographical research of a Jaeger officer, a Civil Guard Chief, a Field Commander Matti Laurila. A broader practice of qualitative methods was utilized in the research. The main aim is a permanent reconstruction and reinterpretation of past events through the experiences of the study object. The life and times of Laurila are intertwined with the crucial events that led to the Finnish Declaration of Independence. Afterwards he helped to ensure that the young republic also stayed independent. As a Jaeger in the winter of 1917 Laurila witnessed an incident he would never forget. After disobeying a direct order, Sven Saarikoski from Lapua was shot dead by his commanding officer, K. A. Ståhlberg, on the ice of the river Aa. Laurila faced the horrors of war at closer quarters, for he lost his father and his brother in the battle of Länkipohja on 16th March 1918. This battle was a major turning point for Laurila and profoundly influenced the rest of his life. The relationship between Laurila and his superiors was problematic almost throughout his military career, haunted as he was by the memory of Sven Saarikoski's execution and the losses in Länkipohja The position of Laurila as an authority in South Ostrobothnia was a key factor in preventing the extreme right from rallying enough Civil Guard troops to escalate the embryonic Mäntsälä rebellion of 1932. After the rebellion Laurila routinely opposed anything he saw as a threat to the independence of the Civil Guard. He would flatly refuse to even consider the integration of the Civil Guard into the national defence force. His uncompromising stand in this matter annoyed some among the higher ranking officers. After the Winter War Laurila got himself into a dispute with Jaeger Colonel H. E. Hannuksela that would have long-lasting consequences. The conflicts between them became widely known in the attack phase of the Continuation War in 1941 at the latest. Laurila had to give up his military career at the end of 1944. In the years that followed he did what he could to ensure that the South Ostrobothnia Civil Guard patrimony remained in the province. Laurila's position as a respected authority in South Ostrobothnia remained unchanged until his death.

Strike Hard, Strike Sure - Operation Musketeer : British Military Planning during the Suez Crisis, 1956

This study analyses British military planning and actions during the Suez Crisis in 1956. It seeks to find military reasons for the change of concepts during the planning and compares these reasons with the tactical doctrines of the time. The thesis takes extensive advantage of military documents preserved in the National Archives, London. In order to expand the understanding of the exchange of views during the planning process, the private papers of high ranking military officials have also been consulted. French military documents preserved in the Service Historique de la Defence, Paris, have provided an important point of comparison. The Suez Crisis caught the British armed forces in the middle of a transition phase. The main objective of the armed forces was to establish a credible deterrence against the Soviet Union. However, due to overseas commitments the Middle East playing a paramount role because of its economic importance the armed forces were compelled to also prepare for Limited War and the Cold War. The armed forces were not fully prepared to meet this demand. The Middle Eastern garrison was being re-organised after the withdrawal from the Canal Base and the concept for a strategic reserve was unimplemented. The tactical doctrines of the time were based on experiences from the Second World War. As a result, the British view of amphibious operations and the subsequent campaigns emphasised careful planning, mastery of the sea and the air, sufficient superiority in numbers and firepower, centralised command and extensive administrative preparations. The British military had realized that Nasser could nationalise the Suez Canal and prepared an outline plan to meet this contingency. Although the plan was nothing more than a concept, it was accepted as a basis for further planning when the Canal was nationalised at the end of July. This plan was short-lived. The nominated Task Force Commanders shifted the landing site from Port Said to Alexandria because it enabled faster expansion of the bridgehead. In addition, further operations towards Cairo the hub of Nasser s power would be easier to conduct. The operational concept can be described as being traditional and was in accordance with the amphibious warfare doctrine. This plan was completely changed at the beginning of September. Apparently, General Charles Keightley, the Commander-in-Chief, and the Chairman of the Chiefs of Staff Committee developed the idea of prolonged aerial operations. The essence of the concept was to break the Egyptian will to resist by attacking the oil facilities, the transportation system and the armed forces. This victory through air concept would be supported by carefully planned psychological operations. This concept was in accordance with the Royal Air Force doctrine, which promoted a bomber offensive against selected target categories. General Keightley s plan was accepted despite suspicions at every planning level. The Joint Planning Staff and the Task Force Commanders opposed the concept from the beginning to the end because of its unpredictability. There was no information that suggested the bombing would persuade the Egyptians to submit. This problem was worsened by the fact that British intelligence was unable to provide reliable strategic information. The Task Force Commanders, who were responsible for the tactical plans, were not able to change Keightley s mind, but the concept was expanded to include a traditional amphibious assault on Port Said due to their resistance. The bombing campaign was never tested as the Royal Air Force was denied authorisation to destroy the transportation and oil targets. The Chiefs of Staff and General Keightley were too slow to realise that the execution of the plan depended on the determination of the Prime Minister. However, poor health, a lack of American and domestic support and the indecisiveness of the military had ruined Eden s resolve. In the end, a very traditional amphibious assault, which was bound to succeed at the tactical level but fail at the strategic level, was launched against Port Said.

Transcriptional regulation of a pineapple polyphenol oxidase gene and its relationship to blackheart.

Two genes encoding polyphenol oxidase (PPO) were isolated from pineapple (Ananas comosus[L.] Merr. cv. Smooth Cayenne). Sequence analyses showed that both contained a single intron and encoded typical chloroplast-localized PPO proteins, the sequences of which corresponded to two pineapple PPO cDNAs, PINPPO1 and PINPPO2, recently described by Stewart et al. (2001). Southern blot analyses suggested that pineapple contained only two PPO genes. Analysis of expression of PINPPO1 promoter GUS fusion constructs showed this promoter had a low basal activity and was cold- and wound-inducible, consistent with known mRNA expression profiles. Striking homologies to gibberellin response complexes (GARC) were observed in sequences of both the PINPPO1 and PINPPO2 promoters. Transient assays in mature pineapple fruit and stable expression in transgenic tobacco showed that PINPPO1 promoter-GUS fusions were indeed gibberellin (GA) responsive. A role for the element within the putative GARCs in mediating GA-responsiveness of the PINPPO1 promoter was confirmed by mutational analysis. PINPPO2 was also shown to be GA-responsive by RT-PCR analysis. Mutant PINPPO1 promoter-GUS fusion constructs, which were no longer GA-inducible, showed a delayed response to cold induction in pineapple fruit in transient assays, suggesting a role for GA in blackheart development. This was supported by observations that exogenous GA3 treatment induced blackheart in the absence of chilling. Sequences showing homology to GARCs are also present in some PPO promoters in tomato, suggesting that GA regulates PPO expression in diverse species.

Visions of Past Glory: Nationalism and the Construction of Early Finnish History

The study is an examination of how the distant national past has been conceived and constructed for Finland from the mid-sixteenth century to the Second World War. The author argues that the perception and need of a national 'Golden Age' has undergone several phases during this period, yet the perceived Greatness of the Ancient Finns has been of great importance for the growth and development of the fundamental concepts of Finnish nationalism. It is a question reaching deeper than simply discussing the Kalevala or the Karelianism of the 1890s. Despite early occurrences of most of the topics the image-makers could utilize for the construction of an Ancient Greatness, a truly national proto-history only became a necessity after 1809, when a new conceptual 'Finnishness' was both conceived and brought forth in reality. In this process of nation-building, ethnic myths of origin and descent provided the core of the nationalist cause - the defence of a primordial national character - and within a few decades the antiquarian issue became a standard element of the nationalist public enlightenment. The emerging, archaeologically substantiated, nationhood was more than a scholarly construction: it was a 'politically correct' form of ethnic self-imaging, continuously adapting its message to contemporary society and modern progress. Prehistoric and medieval Finnishness became even more relevant for the intellectual defence of the nation during the period of Russian administrative pressure 1890-1905. With independence the origins of Finnishness were militarized even further, although the 'hot' phase of antiquarian nationalism ended, as many considered the Finnish state reestablished after centuries of 'dependency'. Nevertheless, the distant past of tribal Finnishness and the conceived Golden Age of the Kalevala remained obligating. The decline of public archaeology is quite evident after 1918, even though the national message of the antiquarian pursuits remained present in the history culture of the public. The myths, symbols, images, and constructs of ancient Finnishness had already become embedded in society by the turn of the century, like the patalakki cap, which remains a symbol of Finnishness to this day. The method of approach is one of combining a broad spectrum of previously neglected primary sources, all related to history culture and the subtle banalization of the distant past: school books, postcards, illustrations, festive costumes, drama, satirical magazines, novels, jewellery, and calendars. Tracing the origins of the national myths to their original contexts enables a rather thorough deconstruction of the proto-historical imaginary in this Finnish case study. Considering Anthony D. Smith's idea of ancient 'ethnies' being the basis for nationalist causes, the author considers such an approach in the Finnish case totally misplaced.

Teollisuuden ja yhteiskunnan palveluksessa : Arkkitehti Bertel Liljequist (1885 - 1954) tuotantolaitosten suunnittelijana maailmansotien välisenä aikana

My thesis concerns the plans drawn up by architect Bertel Liljequist (1885 1954) for an industrial corporation and a city in Finland during the interwar years. These were two quite different clients: the Kymi Company operating in Kuusankoski and the City of Helsinki. My study includes the micro-examination of the wider social issues involved. That the industrial community and factories in Kuusankoski be constructed correctly in a way supporting corporate strategy was of primary importance for the company s operations. Through the planning process for Helsinki s abattoirs, I show how a city dealt with the twin problems of hygiene and increasing demand for food resulting from a growth in population. I clarify how society and its economic, political and class structures affected the practice of architecture and its expression in the built environment. I analyse how the different backgrounds and starting points of the clients affected the construction projects under study and architect Bertel Liljequist s work. In studying Liljequist as an industrial designer, I have considered it vital to ascertain the client s intentions and objectives within the framework of the prevailing social situation. I examine the meanings the client wished the architecture to express and also to communicate to those working in the factory and the area as well as to the workers living on company land. The social outlook of the owners and management of Kymi Company implicitly affected the appearance of the factory. A brick fairface for the factories was a safe and natural material at the beginning of the 1920s when taking into consideration the events of the 1918 Civil War. To have built a White factory in the style of a defence building would have been provocative. Outside the factory gates, however, the company supported White architecture. The company used the factory buildings to manifest its power and the dwellings to bind the workers and make them loyal to the company. Architecture was thus one way in which the company manifested its position as the higher and undisputed authority. The role of the City of Helsinki within the planning process was for its officials to provide expert opinions but also to arrange study trips for the architect and the abattoir s general manager. The city also decided on the standard of the design. The city s responsibility for the health of its inhabitants and the requirements of modern meat production can be seen in the minimal architecture and clear functionality of the plant. The architecture left no doubt about the trustworthiness of the modern city. Translation: Michael Wynne-Ellis

Co-induction of sucrose transport and invertase activities in a thermophilic fungus,Thermomyces lanuginosus

The incorporation of sucrose into the thermophilic fungus,Thermomyces lanuginosus, occurred only in mycelia previously exposed to sucrose or raffinose. Sucrose uptake and invertase were inducible. Both activities appeared in sucrose-induced mycelia at about the same time. Both activities declined almost simultaneously following the exhaustion of sucrose in the medium. The sucrose-induced uptake system was specific for \beta -fructofuranosides as revealed by competition with various sugars. The induction of sucrose uptake system was blocked by cycloheximide, showing that it was dependent on new protein synthesis. Transport of sucrose did not seem to be dependent on ATP. Rather, uptake of this sugar seemed to be driven by a proton gradient across the plasma membrane. The uptake system showed Michaelis-Menten kinetics.

Identification of genes involved with tick infestation in Bos taurus and Bos indicus

Tick resistant cattle could provide a potentially sustainable and environmentally sound method of controlling cattle ticks. Advances in genomics and the availability of the bovine genome sequence open up opportunities to identify useful and selectable genes controlling cattle tick resistance. Using quantitative real-time PCR and the Affymetrix bovine array platform, differences in gene expression of skin biopsies from tick resistant Bos indicus (Brahman) and tick susceptible Bos taurus (Holstein-Friesian) cattle following tick challenge were examined. We identified 138 significant differentially-expressed genes, including several immunological/host defence genes, extracellular matrix proteins, and transcription factors as well as genes involved in lipid metabolism. Three key pathways, represented by genes differentially expressed in resistant Brahmans, were identified; the development of the cell-mediated immune response, structural integrity of the dermis and intracellular Ca 2+ levels. Ca2+, which is implicated in host responses to microbial stimuli, may be required for the enhancement or fine-tuning of transcriptional activation of Ca2+- dependant host defence signalling pathways.

M. bovis BCG induced expression of COX-2 involves nitric oxide-dependent and -independent signaling pathways

In a multifaceted immunity to mycobacterial infection, induced expression of cyclooxygenase-2 (COX-2) by Mycobacterium bovis bacillus Calmette-Guerin (BCG) may act as an important influencing factor for the effective host immunity. We here demonstrate that M. bovis BCG-triggered TLR2-dependent signaling leads to COX-2 and PGE2 expression in vitro in macrophages and in vivo in mice. Further, the presence of PGE2 could be demonstrated in sera or cerebrospinal fluid of tuberculosis patients. The induced COX-2 expression in macrophages is dependent on NF-kappa B activation, which is mediated by inducible NO synthase (iNOS)/NO-dependent participation of the members of Notch1-PI-3K signaling cascades as well as iNOS-independent activation of ERK1/2 and p38 MAPKs. Inhibition of iNOS activity abrogated the M. bovis BCG ability to trigger the generation of Notch1 intracellular domain (NICD), a marker for Notch1 signaling activation, as well as activation of the PI-3K signaling cascade. On the contrary, treatment of macrophages with 3-morpholinosydnonimine, a NO donor, resulted in a rapid increase in generation of NICD, activation of PI-3K pathway, as well as the expression of COX-2. Stable expression of NICD in RAW 264.7 macrophages resulted in augmented expression of COX-2. Further, signaling perturbations suggested the involvement of the cross-talk of Notch1 with members with the PI-3K signaling cascade. These results implicate the dichotomous nature of TLR2 signaling during M. bovis BCG-triggered expression of COX-2. In this perspective, we propose the involvement of iNOS/NO as one of the obligatory, early, proximal signaling events during M. bovis BCG-induced COX-2 expression in macrophages.

Ranskan rooli ja asema läntisessä liittoutumassa neljännen ja viidennen tasavallan vaihtumakohdassa 1956-1958

The study discusses the position of France as the United States’ ally in NATO in 1956-1958. The concrete position of France and the role that it was envisioned to have are being treated from the point of view of three participants of the Cold War: France, the United States and the Soviet Union. How did these different parties perceive the question and did these views change when the French Fourth Republic turned into the Fifth in 1958? The study is based on published French and American documents of Foreign Affairs. Because of problems with accessibility to the Soviet archival sources, the study uses reports on France-NATO relations of Pravda newspaper, the official organ of the Communist Party of the USSR, to provide information about how the Soviet side saw the question. Due to the nature and use of source material, and the chronological structure of the work, the study belongs methodologically to the research field of History of International Relations. As distinct from political scientists’ field of research, more prone to theorize, the study is characteristically a historical research, a work based on qualitative method and original sources that aims at creating a coherent narrative of the views expressed during the period covered by the study. France’s road to a full membership of NATO is being treated on the basis of research literature, after which discussions about France’s position in the Western Alliance are being chronologically traced for the period of last years of the Fourth Republic and the immediate months of coming back to power of Charles de Gaulle. Right from the spring of 1956 there can be seen aspirations of France, on one hand, to maintain her freedom of action inside the Western Alliance and, on the other, to widen the dialogue between the allies. The decision on France’s own nuclear deterrent was made already during the Fourth Republic, when it was thought to become part of NATO’s common defence. This was to change with de Gaulle. The USA felt that France still fancied herself as a great power and that she could not participate in full in NATO’s common defence because of her colonies. The Soviet Union saw the concrete position of France in the Alliance as in complete dependence on the USA, but her desired role was expressed largely in “Gaullist” terms. The expressions used by the General and the Soviet propaganda were close to each other, but the Soviet Union could not support de Gaulle without endangering the position of the French Communist Party. Between the Fourth and Fifth Republics no great rupture in content took place concerning the views of France’s role and position in the Western Alliance. The questions posed by de Gaulle had been expressed during the whole period of Fourth Republic’s existence. Instead, along with the General the weight and rhetoric of these questions saw a great change. Already in the early phase the Americans saw it possible that with de Gaulle, France would try to change her role. The rupture took place in the form of expression, rather than in its content.

Scheffleriläinen rationaalisuus ja kasvatustodellisuuden monikerroksisuus : Jännitteitä ja ratkaisuja Israel Schefflerin kasvatusfilosofiassa

The study is a philosophical analysis of Israel Scheffler’s philosophy of education, focusing on three crucial conceptions in his philosophy: the conception of rationality, the conception of human nature, and the conception of reality. The interrelations of these three concepts as well as their relations to educational theorizing are analysed and elaborated. A conceptual problem concerning Scheffler’s ideal of rationality derives from Scheffler’s supposition of the strong analogy between science education and moral education in terms of the ideal of rationality. This analogy is argued to be conceptually problematic, since the interconnections of rationality, objectivity, and truth, appear to differ from each other in the realms of ethics and science, given the presuppositions of ontological realism and ethical naturalism, to which Scheffler explicitly subscribes. This study considers two philosophical alternatives for solving this problem. The first alternative relates the analogy to the normative concept of personhood deriving from the teleological understanding of human nature. Nevertheless, this position turns out to be problematic for Scheffler, since he rejects all teleological thinking in his philosophy. The problem can be solved, as it is argued, by limiting Scheffler’s rejection of teleology – in light of his philosophical outlook on the whole – in a manner that allows a modest version of a teleological conception of human nature. The second alternative, based especially on Scheffler’s later contributions, is to suggest that reality is actually more complex and manifold than it appears to be in light of a contemporary naturalist worldview. This idea of plurealism – Scheffler’s synthesis of pluralism and realism – is represented especially in Scheffler’s contributions related to his debate with Nelson Goodman dealing with both constructivism and realism. The idea of plurealism is not only related to the ethics-science-distinction, but is more widely related to the relationship between ontological realism and the incommensurable systems of description in diverse realms of human understanding. The Scheffler-Goodman debate is also analysed in relation to the contemporary constructivism-realism debate in educational philosophy. In terms of educational questions, Scheffler’s plurealism is argued as offering a fruitful perspective. Scheffler’s philosophy of education can be interpreted as searching for solutions to the problems deriving from the tension between the tradition of analytical philosophy and the complexity and multiplicity of educational reality. The complexity of reality combined with the supposition of the limitedness of human knowledge does not lead Scheffler to relativism or particularism, but, in contrast, Schefflerian formulations of rationality and objectivity preserve the possibility for critical inquiry in all realms of educational reality. In light of this study, Scheffler’s philosophy of education provides an exceptional example of combining ontological realism, epistemological fallibilism, and the defence of the ideal of rationality, combined with a wide-ranging understanding of educational reality.

Expression of intracellular calcium signalling genes in cattle skin during tick infestation

It is widely acknowledged that changes in intracellular calcium ion (Ca2+) concentration provide dynamic signals that control a plethora of cellular processes, including triggering and mediating host defence mechanisms. In this study, quantitative real-time PCR was used to analyse gene expression of 14 Ca2+ signalling proteins in skin obtained from high tick-resistant (HR) and low tick-resistant (LR) cattle following artificial challenge with cattle tick (Rhipicephalus (Boophilus) microplus). Up-regulation of numerous genes was observed in both HR and LR skin following tick challenge, however substantially higher transcription activation was found in HR tissue. The elevated expression in HR skin of specific Ca2+ signalling genes such as AHNAK, CASQ, IL2, NFAT2CIP and PLCG1 may be related to host resistance. Our data suggest that Ca2+ and its associated proteins might play an important role in host response to ticks and that further investigation is warranted.
