Agriculture at the Crossroads

What a pleasure it is to have this opportunity to welcome you all to this thirteenth annual Agriculture at the Crossroads Conference sponsored by the Nebraska AgRelations Council and the Department of Agricultural Economics here in the Institute of Agriculture and Natural Resources at the University of Nebraska- Lincoln.

Ag at the Crossroads

Thank you for inviting me to be here with you today. It is always such a pleasure to be asked to talk about the ways the Institute of Agriculture and Natural Resources benefits Nebraskans, Nebraska, and our state's economy. I am proud of the real difference our work makes in Nebraska's future and in Nebraskans' lives.

Ag at the Crossroads

Good afternoon. It is always a pleasure to take part in Ag at the Crossroads. I am particularly pleased today to be asked to talk about one of our Institute of Agriculture and Natural Resources' strategic plan priorities and that is water. One of our four strategic plan priority goals is to, "Develop an integrated, multi-disciplinary, multi-functional water resources program addressing Nebraska's needs that provides statewide, national, and international leadership in water quality and quantity management in the next decade."

The long pentraxin PTX3 at the crossroads between innate immunity and tissue remodelling

Innate immunity represents the first line of defence against pathogens and plays key roles in the activation and orientation of the adaptive immune response. The innate immune system comprises both a cellular and a humoral arm. Components of the humoral arm include soluble pattern recognition molecules that recognize pathogen-associated molecular patterns and initiate the immune response in coordination with the cellular arm, therefore acting as functional ancestors of antibodies. Pentraxins are essential constituents of the humoral arm of innate immunity and represent a superfamily of highly conserved acute phase proteins, traditionally classified into short and long pentraxins. Pentraxin 3 (PTX3) is the prototypic member of the long pentraxins subfamily. As opposed to C-reactive protein, whose sequence and regulation have not been conserved during evolution from mouse to man, the evolutionary conservation of sequence, gene organization and regulation of PTX3 has allowed addressing its pathophysiological roles in genetically modified mice, in diverse conditions, ranging from infections to sterile inflammation, angiogenesis and female fertility. Despite this conservation, a number of predominantly non-coding polymorphisms have been identified in the PTX3 gene which, when associated in particular haplotypes, have been shown to be relevant in clinical conditions including infection and fertility. Here we review the studies on PTX3, with emphasis on pathogen recognition, tissue remodelling and crosstalk with other components of the innate immune system.

International social work education at the crossroads

Social work has been a player in the international arena since 1928 when the International Association of Schools of Social Work (IASSW) was founded alongside its sister organisations, the International Federation of Social Workers (IFSW) and the International Council for Social Welfare (ICSW). These divided their remit into education, practice and policy respectively. Their development has been an interesting one, but the details of it need not detain us here. I only want to lay aside the argument that having an interest in the international domain is a new phenomenon in social work. At the same time, I want to emphasise how impressive it is that a profession that has been so tied into modernity, linked to the modern nation-state (Lorenz, 1994) and rooted in local legislation and traditions has such a long-standing history of involvements that have crossed borders to promote understanding and knowledge-building. In these encounters, social work educators and practitioners have engaged with others who were different from them while struggling to make their interactions egalitarian and respectful ones.

[The mental foramen or "the crossroads of the mandible." An anatomic and clinical observation]

This paper presents a clinical and anatomical review of the mental foramen (MF) based on recent publications (since 1990). Usually, the MF is located below the 2nd premolar or between the two premolars, but it may also be positioned below the 1st premolar or below the mesial root of the 1st molar. At the level of the MF, lingual canals may join the mandibular canal (hence the term "crossroads"). Accessory MF are frequently described in the literature with large ethnic variations in incidence. The emergence pattern of the mental canal usually has an upward and posterior direction. The presence and extent of an "anterior loop" of the mental canal may be overestimated with panoramic radiography. Limited cone-beam computed tomography currently appears to be the most precise radiographic technique for assessment of the "anterior loop". The mental nerve exiting the MF usually has three to four branches for innervation of the soft tissues of the chin, lower lip, facial gingiva and mucosa in the anterior mandible. The clinician is advised to observe a safety distance when performing incisions and osteotomies in the vicinity of the MF.
