Chemical Screening Method for the Rapid Identification of Microbial Sources of Marine Invertebrate-Associated Metabolites
No full textMarine invertebrates have proven to be a rich source of secondary metabolites. The growing recognition that marine microorganisms associated with invertebrate hosts are involved in the biosynthesis of secondary metabolites offers new alternatives for the discovery and development of marine natural products. However, the discovery of microorganisms producing secondary metabolites previously attributed to an invertebrate host poses a significant challenge. This study describes an efficient chemical screening method utilizing a 96-well plate-based bacterial cultivation strategy to identify and isolate microbial producers of marine invertebrate-associated metabolites

Head, withers and pelvic movement asymmetry and their relative timing in trot in racing Thoroughbreds in training
No full textBackgroundHorses show compensatory head movement in hindlimb lameness and compensatory pelvis movement in forelimb lameness but little is known about the relationship of withers movement symmetry with head and pelvic asymmetry in horses with naturally occurring gait asymmetries.ObjectivesTo document head, withers and pelvic movement asymmetry and timing differences in horses with naturally occurring gait asymmetries.Study designRetrospective analysis of gait data.MethodsHead, withers and pelvic movement asymmetry and timing of displacement minima and maxima were quantified from inertial sensors in 163 Thoroughbreds during trot-ups on hard ground. Horses were divided into 4 subgroups using the direction of head and withers movement asymmetry. Scatter plots of head vs. pelvic movement asymmetry illustrated how the head-withers relationship distinguishes between contralateral and ipsilateral head-pelvic movement asymmetry. Independent t test or Mann-Whitney U test (P<0.05) compared pelvic movement asymmetry and timing differences between groups.ResultsThe relationship between head and withers asymmetry (i.e. same sided or opposite sided asymmetry) predicts the relationship between head and pelvic asymmetry in 69-77% of horses. Pelvic movement symmetry was significantly different between horses with same sign vs. opposite sign of head-withers asymmetry (P<0.0001). Timing of the maximum head height reached after contralateral (sound') stance was delayed compared to withers (P=0.02) and pelvis (P=0.04) in horses with contralateral head-withers asymmetry.Main limitationsThe clinical lameness status of the horses was not investigated.ConclusionIn the Thoroughbreds with natural gait asymmetries investigated here, the direction of head vs. withers movement asymmetry identifies the majority of horses with ipsilateral and contralateral head and pelvic movement asymmetries. Withers movement should be further investigated for differentiating between forelimb and hindlimb lame horses. Horses with opposite sided head and withers asymmetry significantly delay the upward movement of the head after sound' forelimb stance

Dunfield, Caroline Withers
No full textThis is a gift, a very special gift given to Caroline Withers on the occasion of her marriage to Reverend Henry Dunfield on October 10, 1878. It consists - of 49 watercolour paintings depicting scenes from St. John's and environs, painted by William Frederick Rennie, whose daughter, Emma, was married to Caroline's - brother, John. The paintings are affixed in a large scrapbook album and, considering their age, are in very good condition. - This collection of paintings will be of interest to those researching art history and artistic styles practised in St. John's in the 1870s. They shed much light on - Rennie as a painter, as little of his work has survived. The album should also be of assistance to those researching built heritage in St. John's during this period, as it - shows the location of many buildings which no longer exist, as well as some which do. Of particular interest is the painting of "The Billies", Dr. William Carson's house - at Rostellan, a building which had undergone much external alteration following its construction in the 1820s, until it was torn down in 199?. There are also - paintings of scenes outside St. John's, including Manuels and Topsail. - While there is no indication on any of the paintings that they were painted by William Frederick Rennie, a comparison between these and known examples of his work - have resulted in a strong case for attributing them to him. The subject matter, the style, the medium and the time period all point to Rennie as the artist
Withers vertical movement symmetry is useful for locating the primary lame limb in naturally occurring lameness
No full textBACKGROUND: During orthopaedic assessment of lame horses, a head nod is commonly present in both primary forelimb and hindlimb lame horses. Additional motion metrics that could assist clinicians in correctly differentiating between these two scenarios would be of great clinical value. OBJECTIVES: The primary objective of this study was to examine whether withers movement asymmetry can be used in a clinical setting to distinguish primary forelimb lameness from compensatory head movement asymmetry due to primary hindlimb lameness. STUDY DESIGN: Retrospective, multicentre study. METHODS: Movement asymmetry of head, withers and pelvis was measured using multi-camera optical motion capture, as part of routine lameness investigations at four European equine hospitals. Vertical movement asymmetry parameters from 317 horses trotting in a straight line were compared before and after successful diagnostic analgesia of a single limb. Descriptive statistics, t-tests and linear models were used to analyse the data. RESULTS: In forelimb lame horses, 80%-81% showed head and withers asymmetry both indicating lameness in the same forelimb. In hindlimb lame horses, 69%-72% showed head asymmetry ipsilateral to the lame hindlimb and withers asymmetry diagonal to the lame hindlimb, thus, head and withers asymmetry indicated lameness in different forelimbs. A large (>15 mm) compensatory head nod was seen in 28%-31% of the hindlimb lame horses. In 89%-92% of these, head and withers asymmetry indicated lameness in different forelimbs. Withers asymmetry decreased linearly with reduced head or pelvic asymmetry for both forelimb and hindlimb lame horses. MAIN LIMITATIONS: Compensatory strategies were evaluated on group level to identify common patterns, potentially ignoring uncommon individual strategies. CONCLUSIONS: Withers vertical movement asymmetry metrics can be useful in helping to locate the primary lame limb during quantitative lameness assessment. Head and withers movement asymmetry parameters generally indicate the same forelimb in forelimb lame horses, but different forelimbs in hindlimb lame horses
