Investigation of Factors for a Poor Prognosis in Rutherford 4 Patients Who Undergo Endovascular Treatment.

Current classifications of chronic limb-threatening ischemia (CLTI) are insufficient to identify Rutherford (R) 4 patients with a poor prognosis. This study aimed to investigate the prognostic factors for patients with R4 CLTI who undergo endovascular treatment (EVT) using data from the Tokyo-taMA peripheral vascular intervention research COmraDE (TOMA-CODE) registry and to propose a risk-scoring system. We analyzed the data of 2,248 prospectively enrolled patients from the registry, divided into 3 groups: intermittent claudication (IC), n = 1,185; R4, n = 401; and R5-6, n = 662.

Symbiosis and horizontal gene transfer promote herbivory in the megadiverse leaf beetles.

Beetles that feed on the nutritionally depauperate and recalcitrant tissues provided by the leaves, stems, and roots of living plants comprise one-quarter of herbivorous insect species. Among the key adaptations for herbivory are plant cell wall-degrading enzymes (PCWDEs) that break down the fastidious polymers in the cell wall and grant access to the nutritious cell content. While largely absent from the non-herbivorous ancestors of beetles, such PCWDEs were occasionally acquired via horizontal gene transfer (HGT) or by the uptake of digestive symbionts.

Complete genome of the mutualistic symbiont AIST from a Japanese strain of the pea aphid .

The genome of National Institute of Advanced Industrial Science and Technology (AIST), an obligate bacterial endosymbiont from a Japanese strain of the pea aphid , was determined. The genome sequence provides valuable information for comparative and evolutionary aspects of the intimate insect-microbe mutualism.
