Management of Acute Superior Mesenteric Artery Occlusion by Thrombolytic Therapy
Acute occlusion of the superior mesenteric artery (SMA) causes extensive bowel necrosis, resulting in a poor prognosis with an extremely high mortality rate. An 82-year-old woman was admitted to our hospital with the complaint of abdominal pain. She was diagnosed as having acute SMA occlusion by enhanced CT. Five hours from onset, the first thrombolytic therapy with urokinase was performed, but failed to complete thrombolysis and recanalization of peripheral blood flow. An exploratory laparotomy following the first thrombolytic therapy showed a mild ischemic change in the affected intestine and mesentery, but no sign of necrosis. After the laparotomy, local thrombolytic therapy with angiographic evaluation of blood flow at 24, 36 and 48 h from the first thrombolysis was performed. As a result, the residual thrombus disappeared and all branches of the SMA became well visualized. The patient was discharged well without a second-look operation or major bowel resection. Sequential intermittent thrombolytic therapy with meticulous angiographic evaluation of blood flow is effective for early-stage acute SMA occlusion

Functional and clinical relevance of novel mutations in a large cohort of patients with Cockayne syndrome
BACKGROUND:
Cockayne syndrome (CS) is a rare, autosomal recessive multisystem disorder characterised by prenatal or postnatal growth failure, progressive neurological dysfunction, ocular and skeletal abnormalities and premature ageing. About half of the patients with symptoms diagnostic for CS show cutaneous photosensitivity and an abnormal cellular response to UV light due to mutations in either the ERCC8/CSA or ERCC6/CSB gene. Studies performed thus far have failed to delineate clear genotype-phenotype relationships. We have carried out a four-centre clinical, molecular and cellular analysis of 124 patients with CS
Usefulness of Choline-PET for the detection of residual hemangiopericytoma in the skull base: comparison with FDG-PET
<p>Abstract</p> <p>Background</p> <p>Choline is a new PET tracer that is useful for the detection of malignant tumor. Choline is a precursor of the biosynthesis of phosphatidylcholine, a major phospholipid in the cell membrane of eukaryotic cells. Malignant tumors have an elevated level of phosphatidylcholine in cell membrane. Thus, choline is a marker of tumor malignancy.</p> <p>Method</p> <p>The patient was a 51-year-old man with repeated recurrent hemangiopericytoma in the skull base. We performed Choline-PET in this patient after various treatments and compared findings with those of FDG-PET.</p> <p>Results</p> <p>Choline accumulated in this tumor, but FDG did not accumulate. We diagnosed this tumor as residual hemangiopericytoma and performed the resection of the residual tumor. FDG-PET is not appropriate for skull base tumor detection because uptake in the brain is very strong.</p> <p>Conclusion</p> <p>We emphasize the usefulness of Choline-PET for the detection of residual hemangiopericytoma in the skull base after various treatments, compared with FDG-PET.</p

Integrated omics unveil the secondary metabolic landscape of a basal dinoflagellate
Abstract: Background: Some dinoflagellates cause harmful algal blooms, releasing toxic secondary metabolites, to the detriment of marine ecosystems and human health. Our understanding of dinoflagellate toxin biosynthesis has been hampered by their unusually large genomes. To overcome this challenge, for the first time, we sequenced the genome, microRNAs, and mRNA isoforms of a basal dinoflagellate, Amphidinium gibbosum, and employed an integrated omics approach to understand its secondary metabolite biosynthesis. Results: We assembled the ~ 6.4-Gb A. gibbosum genome, and by probing decoded dinoflagellate genomes and transcriptomes, we identified the non-ribosomal peptide synthetase adenylation domain as essential for generation of specialized metabolites. Upon starving the cells of phosphate and nitrogen, we observed pronounced shifts in metabolite biosynthesis, suggestive of post-transcriptional regulation by microRNAs. Using Iso-Seq and RNA-seq data, we found that alternative splicing and polycistronic expression generate different transcripts for secondary metabolism. Conclusions: Our genomic findings suggest intricate integration of various metabolic enzymes that function iteratively to synthesize metabolites, providing mechanistic insights into how dinoflagellates synthesize secondary metabolites, depending upon nutrient availability. This study provides insights into toxin production associated with dinoflagellate blooms. The genome of this basal dinoflagellate provides important clues about dinoflagellate evolution and overcomes the large genome size, which has been a challenge previously
