Natural History of Odontogenic Infection
Natural History of Odontogenic Infection The usual cause of odontogenic infections is necrosis of the pulp of the tooth, which is followed by bacterial invasion through the pulp chamber and into the deeper tissues. Necrosis of the pulp is the result of deep caries in the tooth, to which the pulp responds with a typical inflammatory reaction. Vasodilation and edema cause pressure in the tooth and severe pain as the rigid walls of the tooth prevent swelling. If left untreated the pressure leads to strangulation of the blood supply to the tooth through the apex and consequent necrosis. The necrotic pulp then provides a perfect setting for bacterial invasion into the bone tissue. Once the bacteria have invaded the bone, the infection spreads equally in all directions until a cortical plate is encountered. During the time of intrabony spread, the patient usually experiences sufficient pain to seek treatment. Extraction of the tooth (or removal of the necrotic pulp by an endodontic procedure) results in resolution of the infection. Direction of Spread of Infection The direction of the infection's spread from the tooth apex depends on the thickness of the overlying bone and the relationship of the bone's perforation site to the muscle attachments of the jaws. If no treatment is provided for it, the infection erodes through the thinnest, nearest cortical plate of bone and into the overlying soft tissue. If the root apex is centrally located, the infection erodes through the thinnest bone first. In the maxilla the thinner bone is the labial-buccal side; the palatal cortex is thicker. -

Cellular and molecular responses of the kidney to IRI are complex and not fully understood. 1 integrins localize to the basal surface of tubular epithelium interacting with extracellular matrix components of the basal membrane, including collagen IV. Whether preservation of tubular epithelium integrity could be a therapeutic approach for IRI was assessed. The effects of HUTS-21 mAb administration, which recognizes an activation-dependent epitope of 1 integrins, in a rat model of IRI were investigated. Preischemic HUTS-21 administration resulted in the preservation of renal functional and histopathologic parameters. Analyses of activated 1 integrins expression and focal adhesion kinase phosphorylation suggest that its deactivation after IRI was prevented by HUTS-21 treatment. Moreover, HUTS-21 impaired the inflammatory response in vivo, as indicated by inhibition of proin- flammatory mediators and the absence of infiltrating cells. -
Hemidesmosomes and Focal Adhesions Treadmill As Separate but Linked Entities During Keratinocyte Migration Anne Pora1, Sungjun Yoon1, Reinhard Windoffer1 and Rudolf E
ORIGINAL ARTICLE See related commentary on pg 1854 Hemidesmosomes and Focal Adhesions Treadmill as Separate but Linked Entities during Keratinocyte Migration Anne Pora1, Sungjun Yoon1, Reinhard Windoffer1 and Rudolf E. Leube1 Hemidesmosomes anchor the epidermal keratin filament cytoskeleton to the extracellular matrix. They are crucial for the mechanical integrity of skin. Their role in keratinocyte migration, however, remains unclear. Examining migrating primary human keratinocytes, we find that hemidesmosomes cluster as ordered arrays consisting of multiple chevrons that are flanked by actin-associated focal adhesions. These hemidesmosomal arrays with intercalated focal adhesions extend from the cell rear to the cell front. New hemidesmosomal chevrons form subsequent to focal adhesion assembly at the cell’s leading front, whereas chevrons and associated focal adhesions disassemble at the cell rear in reverse order. The bulk of the hemidesmosome-focal adhesion composite, however, remains attached to the substratum during cell translocation. Similar hemidesmosome-focal adhesion patterns emerge on X-shaped fibronectin-coated micropatterns, during cell spreading and in leader cells during collective cell migration. We further find that hemidesmosomes and focal adhesions affect each other’s distribution. We propose that both junctions are separate but linked entities, which treadmill coordinately to support efficient directed cell migration and cooperate to coordinate the dy- namic interplay between the keratin and actin cytoskeleton.

The Functions of Uterine Secretions R
Printed in Great Britain J. Reprod. Fert. (1988) 82,875-892 @ 1988 Journals of Reproduction & Fertility Ltd The functions of uterine secretions R. M. Roberts and F. W. Bazer Departments of Biochemistry and Animal Sciences, University of Missouri, Columbia, MO 65211, U.S.A.; and Department of Animal Science, University of Florida, Gainesville, FL 32611, U.S.A. Summary. The likely functions of uterine secretions, often termed histotroph, in the nurture of the early conceptus are reviewed. Particular emphasis has been placed on the pig in which the uterus synthesizes and secretes large amounts of protein in response to progesterone. In this species, which possesses a non-invasive, diffuse type of epithelio- chorial placentation, the secretions provide a sustained embryotrophic environment which is distinct from that of serum. A group of basic proteins dominates these uterine secretions after Day 1 1 of pregnancy and its best characterized member is uteroferrin, an iron-containing acid phosphatase with a deep purple colour. Evidence has accumulated to suggest that uteroferrin, rather than functioning as an acid phosphatase, is involved in transporting iron to the conceptus. Three basic polypeptides which are found non- covalently associated with uteroferrin have been shown to be antigenically closely related to one another and to have arisen by post-translational processing from a common precursor molecule. Their function is unknown. A group of basic protease inhibitors has been identified which bear considerable sequence homology to bovine pancreatic trypsin inhibitor (aprotinin) and may control intrauterine proteolytic events initiated by the conceptuses. The last basic protein so far characterized is lysozyme which is presumed to have an antibacterial role. -

Mammalogy Lecture 12
Mammalogy Lecture 11 - Reproduction I: General Patterns I. Obviously, reproduction is a very important aspect of biology and whole courses are dedicated to it. It’s easy to understand why reproductive traits would be subject to strong selection because of their direct effects on fitness. II. As we might expect, there are three basic types of mammalian reproduction. These correspond to the three major groups of mammals. Differences among these types reflect the degree of intimacy of fetal-maternal contact. A. Monotreme Type - Retain the primitive amniote pattern, but add a period of lactation. - Egg is very large at ovulation, about 3 mm. It moves down the oviduct where it is fertilized, then it’s coated with albumin, then a shell is laid down by a shell gland, and the shell is mineralized (with CaCO3). - Embryo spends 2-3 weeks in the uterus, then it’s laid. It’s large, 15 mm, when it’s laid. - Embryo growth is supported entirely by the yolk that’s enclosed in the egg. B. Metatherian type: - In some superficial ways it’s similar to monotremes, in that metatherians retain a shell membrane around the fertilized egg; a shell gland is present in Müllerian ducts. - However the shell is never mineralized and young are born live after only ca. 12 days, as we’ve seen, they are very altricial (poorly developed). - Initial intrauterine growth is supported by maternally by a placenta. - Metatherian placenta is the choriovitelline type - yolk-sac placenta (Eutherian placenta is called chorioallantoic placenta) C. Placenta Formation - Let’s look at formation of the placenta in Meta- & Eutherians. -

You have accomplished an enormous amount thus far, but the transformation to come is beyond expectation. Third year is challenging, but fun; you‘ll look back a year from now with amazement at the material you‘ve learned, the skills you‘ve acquired, and the new language that gradually becomes second nature. To ease this process, we would like to share with you the material in this guide, starting with lessons from our own experience. Course material is the bedrock of third year. Without knowing and fully understanding prevention, disease control, and the basics of dentistry, even the most technically skilled dental student can not provide patients with successful treatment. Be on time to lectures, don‘t be afraid to ask questions, and take some time to review your notes in the evening. -

Equine Placenta – Marvelous Organ and a Lethal Weapon
Equine placenta – marvelous organ and a lethal weapon Malgorzata Pozor, DVM, PhD, Diplomate ACT Introduction Placenta has been defined as: „an apposition between parent (usually maternal) and fetal tissue in order to establish physiological exchange” (1). Another definition of this important organ was proposed by Steven and Morris: „a device consisting of one or more transport epithelia located between fetal and maternal blood supply” (2). The main function of placenta is to provide an interface between the dam and the the fetus and to allow the metabolic exchange of the the nutrients, oxygen and waste material. The maternal circulation is brought into a close apposition to the fetal circulation, while a separation of these two circulatory systems remain separated (3). A degree and complexity of this „intimate relationship” varies greately between species mostly due to the structural diversity of the extraembryonic membranes of the vertebrates. The early feto-maternal exchange in the equine pregnancy is established as early as on day 22 after fertilization. The fetal and choriovitellin circulations are already present, the capsule ruptures and the allantois is already visible (4). The allantois starts expanding by day 32 and vascularizes approximately 90% of the chorion and fuses with it to form chorioallantois by day 38 of gestation (5). The equine placenta continues increasing its complexity till approximately day 150 of gestation. Equids have epitheliochorial placenta, there are six leyers separating maternal and fetal circulation, and there are no erosion of the luminal, maternal epithelium, like in ruminants (6). Thousands of small chorionic microvilli develop and penetrate into endometrial invaginations.
