Characterization of seediness attributes of blackberry genotypes

Fresh market blackberries can feel “seedy” when consumed. This “seediness” is associated with the presence of pyrenes which are comprised of a single seed enclosed in an endocarp. Small pyrene size

Alopecia and Dermatitis of a Colt

A 3-week-old mare colt entered Stange Memorial Clinic with a large inguinal hernia. The technique of the operation performed on this colt was written up the summer 1945 Veterinary Student, and varied but little from the standard method

Eclampsia

On November 15, 1945, a 3 year old black female Cocker Spaniel was admitted to the Stange Memorial Clinic. The history secured stated that this dog had whelped 4 pups 11 days prior to admittance. A few days following parturition the animal became unsteady in the posterior limbs and went down. Upon examination, the dog was found to be unable to walk due to posterior limb paralysis. The muscles of the hind limbs also showed spasmodic twitchings. The body temperature at this time was 1060 F

Deformity of Hoof Following Injury of the Coronary Band.

An aged Belgian horse was admitted to Stange Memorial Clinic. The owner explained that the horse\u27s hoof had been cut by a wire several months before. Examination revealed that the cut had penetrated the coronary band. At the time the animal was admitted the hoof was growing in 2 separate parts divided at the point of injury and exuberant granulations were forming in the cleft between the 2 parts of the hoof

Sterility

On March 25, 1946, a 41/2 year old female Boston Terrier was admitted to the Stange Memorial Clinic. This animal came in with the history of having failed to conceive during the last 4 heat periods. An enlargement in the inguinal region was first noticed 1 1/2 years prior to admittance. The owner thought this enlargement to be a tumor. The bitch was examined at the time of admittance and the inguinal enlargement, upon palpation, was found to be reducible. With these factors in mind, a tentative diagnosis of reducible inguinal hernia was made

Chronic Gonitis

A 2-year-old Belgian colt entered Stange Memorial Clinic for examination. The owner explained the colt had been running on pasture and was found lame. How long it had been lame was not known

When it Pays to Rush: Interpreting Morphogen Gradients Prior to Steady-State

During development, morphogen gradients precisely determine the position of gene expression boundaries despite the inevitable presence of fluctuations. Recent experiments suggest that some morphogen gradients may be interpreted prior to reaching steady-state. Theoretical work has predicted that such systems will be more robust to embryo-to-embryo fluctuations. By analysing two experimentally motivated models of morphogen gradient formation, we investigate the positional precision of gene expression boundaries determined by pre-steady-state morphogen gradients in the presence of embryo-to-embryo fluctuations, internal biochemical noise and variations in the timing of morphogen measurement. Morphogens that are direct transcription factors are found to be particularly sensitive to internal noise when interpreted prior to steady-state, disadvantaging early measurement, even in the presence of large embryo-to-embryo fluctuations. Morphogens interpreted by cell-surface receptors can be measured prior to steady-state without significant decrease in positional precision provided fluctuations in the timing of measurement are small. Applying our results to experiment, we predict that Bicoid, a transcription factor morphogen in Drosophila, is unlikely to be interpreted prior to reaching steady-state. We also predict that Activin in Xenopus and Nodal in zebrafish, morphogens interpreted by cell-surface receptors, can be decoded in pre-steady-state.Comment: 18 pages, 3 figure
