Three-dimensional surface reconstruction from multistatic SAR images.

This paper discusses reconstruction of three-dimensional surfaces from multiple bistatic synthetic aperture radar (SAR) images. Techniques for surface reconstruction from multiple monostatic SAR images already exist, including interferometric processing and stereo SAR. We generalize these methods to obtain algorithms for bistatic interferometric SAR and bistatic stereo SAR.

Bonding corneal tissue: applications of photoactivated diazopyruvoyl cross-linking agent.

Photoactivated bis-diazopyruvamide-N,N'-bis(3-diazopyruvoyl)-2,2'-(ethylenedioxy)bis-(ethylamine), (DPD)-was previously shown to bond materials containing type I collagen. However, tensile strength of bonded collagenous tissue ( approximately 78% water) was low compared with that of dehydrated collagenous gelatin ( approximately 14% water). Here we investigated the role of water in corneal tissue bond strength and in bonding corneal tissue to glass.

The yeast Snm1 protein is a DNA 5'-exonuclease.

Interstrand cross-links (ICL) in DNA arise from bifunctional alkylating agents, including nitrogen mustards, mitomycin C and psoralens. Such adducts prevent normal transcription or replication and are mutagenic. Therefore, cellular mechanisms for removing ICL damage are needed to maintain genome stability.

Insulin glulisine provides improved glycemic control in patients with type 2 diabetes.

Objective: Insulin glulisine is a novel analog of human insulin designed for use as a rapid-acting insulin. This study compared the safety and efficacy of glulisine with regular human insulin (RHI) in combination with NPH insulin.

Research Design And Methods: In total, 876 relatively well-controlled patients with type 2 diabetes (mean HbA1c 7.

Direct interaction of FANCD2 with BRCA2 in DNA damage response pathways.

Fanconi anaemia (FA) is a chromosomal instability disorder characterized by cellular sensitivity to DNA interstrand crosslinking agents and a high risk of cancer. Six of the eight proteins encoded by the known FA genes form a nuclear complex which is required for the monoubiquitination of the FANCD2 protein. FANCD2 complexes and colocalizes with BRCA1, but its presumptive role in DNA repair has not yet been clearly defined.

Gestational diabetes: Is there a relationship between leg length and glucose tolerance?

Objective: To assess the relationship between leg length and glucose tolerance in pregnancy.

Research Design And Methods: The leg length and leg-to-height percentage were prospectively determined on 161 glucose-tolerant women during pregnancy and 61 women with gestational diabetes mellitus (GDM).

Results: Women with GDM were a mean of 2.

Gestational diabetes mellitus: compliance with testing.

An audit of birth records of two public and one private hospital was undertaken, over a 6-month period, to determine compliance with the local policy that all women are tested for gestational diabetes mellitus (GDM). Overall 92.1% of women were tested for GDM.

siRNA depletion of BRCA1, but not BRCA2, causes increased genome instability in Fanconi anemia cells.

BRCA1 and BRCA2 proteins act in repair of interstrand crosslinks (ICLs) and maintenance of genome stability and are known to be part of the Fanconi anemia (FA) pathway. We have investigated the role of the BRCA1 and BRCA2 genes in genome stability following ICL damage in normal and FA cells. To circumvent cell lethality of complete disruptions in BRCA1 or BRCA2, small inhibitory RNA (siRNA) was used to transiently deplete the expression of the proteins.

The effect of prandial glucose regulation with repaglinide on treatment satisfaction, wellbeing and health status in patients with pharmacotherapy naïve Type 2 diabetes: a placebo-controlled, multicentre study.

This prospective, 16-week, randomised, double-blind, parallel-group study assessed the differential impact of the prandial glucose regulating oral hypoglycaemic drug, repaglinide, and placebo upon perceptions of quality of life (QoL) and treatment satisfaction in pharmacotherapy-naive patients with Type 2 diabetes. In addition, the study assessed whether these outcomes were influenced by the patients' level of glycaemic control. A total of 253 patients were randomised in a 2:1 ratio of repaglinide: placebo, with doses taken flexibly with main meals (2-4 per day), whenever they were eaten.

Twin pregnancy outcomes for women with gestational diabetes mellitus compared with glucose tolerant women.

Objective: To examine pregnancy outcomes for women with gestational diabetes mellitus (GDM) and a twin pregnancy compared with glucose tolerant women with a twin pregnancy.

Design: Comparison of selected pregnancy outcomes.

Setting: Wollongong, New South Wales, Australia.

Repaglinide in combination therapy.

Type 2 diabetes mellitus (T2DM) is a progressive disorder requiring increasingly aggressive treatment to achieve and maintain target blood glucose concentrations in the presence of deteriorating insulin secretion and increasing insulin resistance. Diet and lifestyle modification are often sufficient initially; however, most patients eventually require pharmacological intervention. With disease progression, monotherapy becomes less effective, so combination therapy is required, using drugs with complementary modes of action to maximise glycaemic control.

Gestational diabetes mellitus: is a diagnosis associated with an increase in maternal anxiety and stress in the short and intermediate term?

Objective: To examine anxiety levels of women diagnosed with gestational diabetes mellitus (GDM) and to compare these with glucose-tolerant (GT) women at similar stages of pregnancy.

Research Design And Methods: Prospective longitudinal study conducted on 50 women with GDM and 50 GT women. All women completed the Mental Health Inventory (MHI-5) forms and the Speilberger State-Trait Anxiety Inventory (STAI) at the beginning of the third trimester, antepartum, and 6 weeks postpartum.

Acarbose improves glycemic control in overweight type 2 diabetic patients insufficiently treated with metformin.

Objective: To investigate the efficacy and safety of acarbose as add-on therapy in overweight type 2 patients with diabetes inadequately controlled by metformin.

Research Design And Methods: This study adopted a multicenter, randomized, double-blind, placebo-controlled, parallel group design. After a 4-week placebo run-in period, subjects were randomized to either acarbose (titrated up to 100 mg b.

The beta-lactamase motif in Snm1 is required for repair of DNA double-strand breaks caused by interstrand crosslinks in S. cerevisiae.

The SNM1 gene of Saccharomyces cerevisiae is specific for repair of DNA interstrand crosslinks (ICLs). We report that the SNM1 gene functions in steps needed for the reformation of chromosomal DNA after double-strand breaks (DSBs) made in the process of ICL repair. However, SNM1 function is not needed for repair of HO endonuclease-generated DSBs.

BRCA1 interacts directly with the Fanconi anemia protein FANCA.

Fanconi anemia (FA) is a rare autosomal recessive disease characterized by skeletal defects, anemia, chromosomal instability and increased risk of leukemia. At the cellular level FA is characterized by increased sensitivity to agents forming interstrand crosslinks (ICL) in DNA. Six FA genes have been cloned and interactions among individual FANC proteins have been found.

S. cerevisiae has three pathways for DNA interstrand crosslink repair.

Yeast mutants, snm1 (pso2-1), rev3 (pso1-1), and rad51, which display significant sensitivity to interstrand crosslinks (ICLs) have low relative sensitivity to other DNA damaging agents. SNM1, REV3, and RAD51 were disrupted in the same haploid strain, singly and in combination. The double mutants, snm1 Delta rev3 Delta, snm1 Delta rad51 Delta and rev3 Delta rad51 Delta were all more sensitive to ICLs than any of the single mutants, indicating that they are in separate epistasis groups for survival.

DNA damage processing defects and disease.

Inherited defects in DNA repair or the processing of DNA damage can lead to disease. Both autosomal recessive and autosomal dominant modes of inheritance are represented. The diseases as a group are characterized by genomic instability, with eventual appearance of cancer.

Extracellular matrix molecules improve periodontal ligament cell adhesion to anorganic bone matrix.

Bone replacement graft (BRG) materials are used in periodontal therapy to encourage new bone formation. Extracellular matrix proteins may improve periodontal ligament fibroblast (PDLF) attachment to these materials. We demonstrate that PDLFs adhere well to the extracellular matrix (ECM) proteins fibronectin, vitronectin, laminin, and collagen types I and IV.

The putative collagen binding peptide hastens periodontal ligament cell attachment to bone replacement graft materials.

Background: Bone replacement graft (BRG) materials are often used to treat periodontal defects, to promote cellular invasion, and to encourage bone regrowth. Periodontal ligament fibroblasts (PDLF) incorporate these materials and form the basis of the renewed connection between the existing and newly formed alveolar bone and the tooth surface. A peptide (P-15) that mimics the putative cell-binding domain of collagen has been reported to promote dermal fibroblast attachment and proliferation.
