Excretory urography can track down morphological changes in the urinary bladder associated with urachal anomalies in calves for early diagnosis
OBJECTIVE
To investigate radiographic detection by excretory urography of morphological changes in the urinary bladder associated with urachal anomalies in calves.
METHODS
Excretory urography was performed to detect morphological changes in the urinary bladder of 13 calves, of which 6 were nondysuric with swelling of umbilical region and 7 were dysuric without clinical umbilical swelling from November 2022 through April 2024.
RESULTS
The urinary bladder was delineated in all 13 calves after excretory urography. The aspect ratios (length:height), which objectively evaluate the shape of the urinary bladder, ranged from 1.08 to 2.43 (1.90 in average) and 1.34 to 11.89 (4.75 in average) in nondysuric and dysuric calves, respectively. The ratios of calves with nondysuric were significantly lower than those of dysuric (P < .05).
CONCLUSIONS
Excretory urography could play an important role in evaluating abnormal morphological changes due to urachus anomalies in the urinary bladder of calves.
CLINICAL RELEVANCE
Among calves with dysuria, urachal anomaly should be included in the differential diagnosis. Excretory urography is proposed as an alternative option for early diagnosis among calves presenting with dysuria to improve livestock productivity.journal articl

An Evolutionarily Conserved Plant RKD Factor Controls Germ Cell Differentiation
In contrast to animals, in which the germ cell lineage is established during embryogenesis, plant germ cells are generated in reproductive organs via reprogramming of somatic cells. The factors that control germ cell differentiation and reprogramming in plants are poorly understood. Members of the RKD subfamily of plant-specific RWP-RK transcription factors have been implicated in egg cell formation in Arabidopsis based on their expression patterns and ability to cause an egg-like transcriptome upon ectopic expression [1]; however, genetic evidence of their involvement is lacking, due to possible genetic redundancy, haploid lethality, and the technical difficulty of analyzing egg cell differentiation in angiosperms. Here we analyzed the factors that govern germ cell formation in the liverwort Marchantia polymorpha. This recently revived model bryophyte has several characteristics that make it ideal for studies of germ cell formation, such as low levels of genetic redundancy, readily accessible germ cells, and the ability to propagate asexually via gemma formation [2, 3]. Our analyses revealed that MpRKD, a single RWP-RK factor closely related to angiosperm RKDs, is preferentially expressed in developing eggs and sperm precursors in M. polymorpha. Targeted disruption of MpRKD had no effect on the gross morphology of the vegetative and reproductive organs but led to striking defects in egg and sperm cell differentiation, demonstrating that MpRKD is an essential regulator of germ cell differentiation. Together with previous findings [1, 4?6], our results suggest that RKD factors are evolutionarily conserved regulators of germ cell differentiation in land plants.journal articl
へん長回転だ円体状空かを有する半無限体の二軸一様引張り
