Premise Of The Study: The American Cross Timbers forest ecosystem runs from southeastern Kansas to Central Texas and is primarily composed of post oak (Quercus stellata). This old-growth forest currently occupies only about 2% of its ancestral range. To facilitate genetic research on this species, we developed microsatellite primers specific to post oak from reduced genomic libraries. •
Methods And Results: Two Q. stellata individuals, sampled from the northern and southern range of the post oak forest, were subject to genomic reduction and 454 pyrosequencing. Bioinformatic analysis identified putative microsatellites from which 12 polymorphic primer sets were screened on three populations. The number of alleles observed ranged from five to 20 across all populations, while observed and expected heterozygosity values ranged from 0.05 to 0.833 and 0.236 to 0.893, respectively, within individual populations. •
Conclusions: We report the development of microsatellite markers, specific to post oak, to aid the study of genetic diversity and population structure of extant forest remnants.

Hymenoscyphus fraxineus, the causal agent of Ash Dieback (ADB), has been introduced to eastern Europe in the 1990s from where it spread causing decline in European ash populations. However, the genetic basis of the molecular response in tolerant and susceptible ash trees to this disease is still largely unknown. We performed RNA-sequencing to study the transcriptomic response to the disease in four ash genotypes (ADB-tolerant FAR3 and FS36, and ADB-susceptible UW1 and UW2), during a time-course of 7, 14, 21, and 28 days post-inoculation, including mock-inoculated trees as control samples for each sampling time point.

We present a case of a unique midfoot injury pattern including dislocations of the calcaneocuboid and naviculocuneiform joints with associated calcaneus and navicular fractures after low-energy injury. This combination of injuries is rare, especially with a low-energy mechanism. There are no current treatment guidelines.

Background: Split tendon transfer of the posterior tibialis (SPOTT) is a surgical procedure in which the split posterior tibialis tendon is transferred posterior to the fibula (PO) with insertion on the peroneus brevis tendon to rebalance the forces across the hindfoot. Routing of the split tendon through the interosseous membrane (IO) is a variation with the potential benefit of augmenting ankle dorsiflexion in swing.
Research Question: Does IO routing improve ankle dorsiflexion in swing and/or varus in stance compared to PO routing?
Methods: A retrospective chart review was completed to identify forty-two patients who underwent a SPOTT procedure for equinovarus foot deformity.

Background: Mycobacterium bovis BCG is the human tuberculosis vaccine and is the oldest vaccine still in use today with over 4 billion people vaccinated since 1921. The BCG vaccine has also been investigated experimentally in cattle and wildlife by various routes including oral and parenteral. Thus far, oral vaccination studies of cattle have involved liquid BCG or liquid BCG incorporated into a lipid matrix.
