Immunohistochemical expression of TLR-4 in temporomandibular joint dysfunction.

Toll-like receptor 4 (TLR-4) is a transmembrane protein involved in the innate immune system and has been implicated in the pathogenesis of temporomandibular joint dysfunction (TMD). The purpose of this study was to histologically examine the level of expression of TLR-4 relative to severity of TMD. Thirty-one human TMJ disc samples were immunostained for TLR-4 and evaluated for intensity of stain.

Immunohistochemical analysis of IL-1 Receptor 1 in the discs of patients with temporomandibular joint dysfunction.

Objective Temporomandibular joint dysfunction (TMD) may affect a patient's quality of life, and one of the etiologies can be anterior disc displacement with reduction (ADDwR) and anterior disc displacement without reduction (ADDWoR). Interleukin 1 Receptor 1 (IL-1R1) is a membrane receptor that plays an important role on initiating immune and inflammatory response by binding the agonists ligands of IL-1 alpha and IL-1 beta. Therefore, the aim of this study was to evaluate, through immunohistochemical analysis, the association of IL-1R1 with TMD.

Influence of Atopy in the Outcome of Avulsed and Replanted Teeth during 5 Years of Follow-up.

Introduction: The goal of replantation after dental avulsion is to maintain the tooth in its socket. Presence of vital periodontal ligament cells on the root surface of the replanted tooth and the immunologic status of the patient are factors that protect against root resorption. It is known that dental constituents play an active role in root resorption by inducing specific and non-specific immune responses; however, little information exists regarding the influence of the acquired immune response on replantation.

A re-analysis of studies regarding the use of spp. in women during pregnancy.

The use of herbal medicines as a form of primary and adjunctive healthcare continues to grow internationally. It is therefore important that healthcare practitioners stay abreast of potential contraindications that may arise when these medicines are taken together with orthodox treatment or are prescribed during pregnancy. This article analyses the most popularly cited clinical research concerning the use of spp.

Kinematic determinants of weapon velocity during the fencing lunge in experienced épée fencers.

The lunge is the most common attack in fencing, however there is currently a paucity of published research investigating the kinematics of this movement. The aim of this study was to investigate if kinematics measured during the épée fencing lunge had a significant effect on sword velocity at touch and whether there were any key movement tactics that produced the maximum velocity. Lower extremity kinematic data were obtained from fourteen right handed club épée fencers using a 3D motion capture system as they completed simulated lunges.

Comparison of muscle strength and in-vivo muscle morphology in young children with haemophilia and those of age-matched peers.

Recent advances in imaging have enhanced our understanding of the morphological adaptations of muscle in response to disease and altered use. Adaptation in muscle morphology has been linked to changes in muscle strength. To date, no studies have compared muscle morphology and strength in young children with haemophilia to that of typically developing children.

Anglo-Saxon pharmacopoeia revisited: a potential treasure in drug discovery.

Three of the four major Anglo-Saxon collections reporting medicinal formulations in England from the 10th century, the Old English Herbarium, Bald's Leechbook and the Lacnunga, could contain leads and insights into new medicinal uses. Previous pharmacological studies of medicinal plants mentioned in Anglo-Saxon medical texts suggested that some were effective and led to the identification and isolation of natural compounds. For example, matricin from yarrow Achillea millefolium L.
