... Abstract Effective therapies for congenital heart disease (CHD) are an urgent clinical need. Insights gained from fundamental scientific research, together with the results of clinical trials, are beginning to yield potential new strategies for treating CHD. Novel discoveries in tissue...

... Although most bleeding disorders are disorders of platelets, coagulation factors (e.g., von Willebrand disease and hemophilia), or fibrinolysis, sometimes patients bleed when there is nothing wrong with any of these things. Instead, they bleed because of defects in the connective tissue...

... Abstract Adipose tissue is an important target of androgen action in humans. Androgens exert important effects on adipose tissue biology, including fat mass expansion and distribution, insulin signalling and lipid metabolism. In conditions of female androgen excess such as polycystic ovary...

... carbohydrates and thus inactivated. For cavitated lesions, controlling them usually involves the placement of restorations to rebuild the cleansability of the surface. In this case, dental practitioners have traditionally removed carious tissues prior to the restoration. This has historically been for a number...

... Abstract Describing and quantifying how much carious tissue should be removed prior to placing a restoration has been a long-debated issue stretching back as far as G.V. Black's “complete caries removal,” now known as non-selective carious tissue removal. Originating in the 1960s and 1970s...

..., evidence supports sealing shallow and moderate deep lesions into dentine. For cavitated lesions, sealing lesions without carious tissue removal might be an option when removal of tooth tissue is not required to provide a hard periphery around the lesion/cavity margin (to enhance bonding or to increase...

... and a restoration placed. The Hall Technique is a method for managing carious primary molar teeth where a preformed stainless-steel crown, also known as a preformed metal crown, is seated over a tooth, sealing in, and not removing carious tissue. This chapter discusses the rationale behind the Hall Technique...

... are lesions that are considered to be progressing at the time of examination. Active dentine lesions are yellowish or light brownish in colour and are typically covered by a microbial deposit. The carious tissue feels soft or leathery on gentle probing (Table 3 ). Inactive lesions are considered...

... been based around the clinical consequences of the disease: soft, leathery, firm and hard dentine. The 3 main carious tissue removal options are described as: (1) selective removal of carious tissue (to both soft and firm dentine), (2) stepwise removal, and (3) non-selective removal to hard dentine...

... Abstract Non-cleansable carious lesions where sealing is no longer an option should be restored in the vast majority of cases. Prior to restoring the cavity, carious tissue removal is performed, mainly to increase the longevity of the restoration. Such removal, however, should not be conducted...

... Abstract Lipid storage and release from fat cells in adipose tissue are key factors in the regulation of the energy balance. During infancy and adolescence, adipose tissue is growing by a combination of increase in fat cell size (to a lesser extent) and (above all) the number of these cells...

... Abstract The aging process affects every aspect of the body, with the face being one of the first places to show signs. Patient-driven demands for safe and effective minimally invasive aesthetic procedures has allowed for an expansive and competitive market for dermal fillers. Soft tissue...

...Clinical Features and Team Work Soft tissue neoplasms comprise a heterogeneous group of lesions with mesenchymal differentiation. Sarcomas are rare, constituting less than 1% of all malignant neoplasms. Benign soft tissue tumors are estimated to be approximately 100 times more frequent than...

...Adipocytic Tissue Fine-needle aspiration smears of fat tissue show clusters of fat cells with an abundant univacuolated cytoplasm or empty space after the cytoplasm and peripherally situated small nuclei. Slender capillaries are frequent findings in the clusters. Smears from reactive fat...

... Abstract The definition of soft tissue and bone sarcomas include a large group of several heterogeneous subtypes of mesenchymal origin that may occur at any age. Among the different sarcomas, rhabdomyosarcoma, synovial sarcoma, Ewing sarcoma and osteosarcoma are aggressive high-grade...

... Abstract There is mounting evidence suggesting a genetic contribution to the susceptibility of sustaining a musculoskeletal soft-tissue injury. To date, more than 70 loci have been implicated in several injury profiles. The genes implicated through these loci encode a broad spectrum of matrix...

... Abstract Tissue reaction to orthodontic force has been a subject of research with the purpose of providing the orthodontists with information necessary for the application of a force system that can generate a maximum of tooth movement and modeling of the alveolar process with a minimum...
