Purpose: This study determined if anterior talofibular ligament (ATFL)/superior extensor ankle retinaculum (SEAR) thicknesses are related to dynamic balance in individuals with chronic ankle instability (CAI). Materials and Methods: The subjects were 14 males and 15 females (age=24.52±3.46 years). Ankle instability was assessed using the Cumberland Ankle Instability Tool (CAIT) with a cut off score of 25 to define two groups. SonoSite MTurbo (Fugifilm Sonosite, Inc.) musculoskeletal ultrasound (MSKUS) unit was used to assess ATFL and SEAR thicknesses. Dynamic balance was measured with the Y Balance Test (YBT) and two NeuroCom balance tests. Results: There were no significant differences in the average ATFL thickness between stable and unstable ankles in those subjects with CAI (0.25±0.03 cm and 0.21±0.05 cm, respectively) or in the SEAR thickness (0.09±0.04 cm and 0.10±0.03 cm, respectively). There were also no significant differences in the right and left ATFL thicknesses (0.23±0.07 cm and 0.21±0.04 cm, respectively) or the SEAR thicknesses (0.09±0.01 cm and 0.09±0.01 cm, respectively) in those without CAI. There were no differences between limbs in composite scores on YBT in those with CAI (p=0.35) and those without CAI (p=0.33). There was a moderate correlation between the left SEAR thickness and the large forward/backward perturbations on the NeuroCom (Natus) motor control test (r=0.51, p=0.006 and r=0.54, p=0.003, respectively). Conclusion: There were no differences in the ATFL/SEAR thicknesses or balance measures between or within the groups, likely because CAI is multi-factorial and related to mechanisms other than tissue changes alone. More sensitive technology and a better definition of the measurement process may provide more definitive results.

Life Science : Hoiamide D, a marine cyanobacteria-derived inhibitor of p53/MDM2 interaction
( Karla L Malloy ),( Hyuk Jae Choi ),( Catherine Fiorilla ),( Fred A Valeriote ),( Teatulohi Matainaho ) 영남대학교 약품개발연구소 2012 영남대학교 약품개발연구소 연구업적집 Vol.22 No.0
Bioassay-guided fractionation of two cyanobacterial extracts from Papua New Guinea has yieldedhoiamide D in both its carboxylic acid and conjugate base forms. Hoiamide D is a polyketide synthase (PKS)/non-ribosomal peptide synthetase (NRPS)-derived natural product that features two consecutive thiazolines and a thiazole, as well as a modified isoleucine residue. Hoiamide D displayed inhibitory activity against p53/MDM2 interaction (EC(50)=4.5 μM), an attractive target for anticancer drug development.

<P>Sources of plasma glucose and glucose turnover were investigated in 8-week-old (pre-diabetic) and 13-week-old (diabetic) Zucker (fa/fa) rats after a 24-h fast. Intraperitoneal (2)H(2)O was administered and [3,4-(13)C(2)]glucose and [U-(13)C(3)]propionate were infused into conscious active rats. (13)C nuclear magnetic resonance analysis of monoacetone glucose derived from blood glucose indicated that glucose production was increased significantly in 8- and 13-week-old fa/fa rats compared with age-matched Zucker (+/+) rats, and hepatic glycogen was dramatically higher among fa/fa animals regardless of age. Glycogenolysis, essentially 0 in +/+ rats after a 24-h fast, was significant in fa/fa rats (11 +/- 6 and 17 +/- 7% of glucose production in 8- and 13-week-old rats, respectively), even after a 24-h fast. Tricarboxylic acid (TCA) cycle flux and efflux of carbon skeletons from the cycle (cataplerosis) were both significantly higher in fa/fa rats compared with controls, but net gluconeogenesis from the TCA cycle was not higher because products leaving the cycle were returned to the cycle via a pyruvate cycling pathway. Thus, pyruvate cycling flux increased in proportion to TCA cycle flux, leaving net gluconeogenesis unchanged in fa/fa animals compared with control animals. The distribution of (2)H in skeletal muscle glycogen suggested that at least a fraction of glucose molecules entering glycogen pass through phosphomannose isomerase.</P>

Several groups of structurally-related compounds, comprised of either five or six-memberedring structures with attached lipophilic carbon chains and in some cases possessing halogen atoms, have been isolated from various marine algae and filamentous cyanobacteria. The related compounds considered in the present work include the coibacins, laurenciones, honaucins, malyngamides and the tumonoic acids. Members of all of these compound families were assayed and found to inhibit the production of nitric oxide in lipopolysaccharides-stimulated macro-phages, indicating their anti-inflammatory potential In addition, several of these same marine natural products were found to inhibit quorum sensing mediated phenotypes in Vibrio harveyi BB120 and /or Escherichia coli JB525. The mechanism and evolutionary significance for inhibition of these cellular processes in prokaryotic and eukaryotic systems are speculated on and discussed.
