  • The vast majority of published cytogenetic studies of malignancy have been of leukemias and related hematologic disorders (see Fig. 1), even though these constitute only about 20% of all cancers. It follows that most of what is known about the clinical applications of cytogenetic studies has been derived from hematologic malignancies.

  • Studies assessing the role of ICTP levels in GCF or peri-implant crevicular fluid as a diagnostic marker of periodontal disease activity have reported promising results so far (Oringer et al. 1998, 2002). ICTP was suggested to predict future bone loss, to correlate with clinical parameters and putative periodontal pathogens and also to reduce following periodontal therapy (Giannobile 1999).

  • The clinical microbiology laboratory is often a sentinel for the detection of drug resistant strains of microorganisms. Standardized protocols require continual scrutiny to detect emerging phenotypic resistance patterns. The timely notification of clinicians with susceptibility results can initiate the alteration of antimicrobial chemotherapy and improve patient care. It is vital that microbiology laboratories stay current with standard and emerging methods and have a solid understanding of their function in the war on infectious diseases. ...

  • An ovarian cyst may be found on the surface of an ovary or inside it. A cyst contains fluid. Sometimes it contains solid tissue too. Most ovarian cysts are benign (not cancer). Most ovarian cysts go away with time. Sometimes, a doctor will find a cyst that does not go away or that gets larger. The doctor may order tests to make sure that the cyst is not cancer.

  • Products of nanotechnology are expected to revolutionize modern medicine, as evidenced by recent scientific advances and global initiatives to support nanotechnology and nanomedicine research. The field of drug delivery is a direct beneficiary of these advancements. Due to their versatility in targeting tissues, accessing deep molecular targets, and controlling drug release, nanoparticles are helping address challenges to face the delivery of modern, as well as conventional drugs.

  • In Canada, other factors such as digester insulation, because of cold weather, also influence the final cost of such a system. To be economical, digester capital cost must be offset by energy savings, fertilizer use, and bedding replacement . Another disadvantage 17 is that fresh poultry manure can be hauled as solid manure, but if digested, the dilution water would increase the original volume by about four times . As well, the biogas produced has low energy per unit volume and can only be used for on-site operations such as running an electrical generator.

  • The key component of osteocyte’s mechanosensing apparatus is the pericellular matrix. limited electron microscope studies reveal that this fluffy “jungle” consists of nanoscale fibrous structures, (about 100nm thick), filling the tiny gap between the cell membrane and the bone matrix. Mechanically, it controls the hydraulic permeability of the bone tissue, determining how easy fluid flows around the cells under external loading.

  • The effect of chitosan, glucose and chitosan–glucose complex (CGC) on the microbial and postharvest quality of shiitake (Lentinus edodes) mushroom stored at 4 ± 1 C for 16 days was investigated. Mushroom weight loss, respiration rate, firmness, ascorbic acid, total soluble solids, microbial and sensory quality were measured. The results indicate that treatment with CGC coating maintained tissue firmness, inhibited increase of respiration rate, reduced microorganism counts, e.g., pseudomonads, yeasts and moulds, compared to uncoated control mushroom.

  • The purpose of this book is to provide both an introduction and a state-of-the-art review of the essential physics and signal processing principles of diagnostic ultrasound in a single reference volume with a unified approach. This book draws together many of the ideas from seminal papers, the author’s research, and other sources in a single narrative and point of view. Unlike texts that present only the theory of acoustic fundamentals, this book relates topics to each other in the context of ultrasound imaging and practical application.

  • For subsequent analysis of the specimen, the needles may be rinsed into a physiologic solution, tissue culture medium, transportation medium or proprietary fixative for liquid based processing. Needles should not be re-sheathed using a two handed technique and instead should be discarded directly into an OSHA approved sharps disposal container. 9 For cystic lesions, remove as much fluid as possible. The cyst fluid can be handled as a liquid specimen. If there is a residual mass, the procedure for solid lesions as described above should be followed.

  • Disseminated Intravascular Coagulation DIC is a clinicopathologic syndrome characterized by widespread intravascular fibrin formation in response to excessive blood protease activity that overcomes the natural anticoagulant mechanisms. DIC is associated with several underlying pathologies (Table 110-2). The most common causes are bacterial sepsis, malignant disorders such as solid tumors or acute promyelocytic leukemia (APL), and obstetric causes. DIC is diagnosed in almost half of pregnant women with abruptio placentae or with amniotic fluid embolism.

  • Abstract Resistance to conventional anticancer therapies in patients with advanced solid tumors has prompted the need of alternative cancer therapies. Moreover, the success of novel cancer therapies depends on their selectivity for cancer cells with limited toxicity to normal tissues. Several decades after Coley's work a variety of natural and genetically modified non-pathogenic bacterial species are being explored as potential antitumor agents, either to provide direct tumoricidal effects or to deliver tumoricidal molecules.

  • Cartilage provides our joints with load support and lubrication for decades of continuous use with minimal friction or damage. These unusual bearing properties are in fact due to a biphasic tissue structure (containing both fluid and solid matrices) and the pressurization of interstitial fluid during dynamic deformations.
