Contrast-enhanced CMR in patients after percutaneous closure of the left atrial appendage: A pilot study
No full textAbstract Background To evaluate the feasibility and value of first-pass contrast-enhanced dynamic and post-contrast 3D CMR in patients after transcatheter occlusion of left atrial appendage (LAA) to identify incorrect placement and persistent leaks. Methods 7 patients with different occluder systems (n = 4 PLAATO; n = 2 Watchman; n = 1 ACP) underwent 2 contrast-enhanced (Gd-DOTA) CMR sequences (2D TrueFISP first-pass perfusion and 3D-TurboFLASH) to assess localization, artifact size and potential leaks of the devices. Perfusion CMR was analyzed visually and semi-quantitatively to identify potential leaks. Results All occluders were positioned within the LAA. The ACP occluder presented the most extensive artifact size. Visual assessment revealed a residual perfusion of the LAA apex in 4 cases using first-pass perfusion and 3D-TurboFLASH indicating a suboptimal LAA occlusion. By assessing signal-to-time-curves the cases with a visually detected leak showed a 9-fold higher signal-peak in the LAA apex (567 ± 120% increase from baseline signal) than those without a leak (61 ± 22%; p Conclusion This CMR pilot study provides valuable non-invasive information in patients after transcatheter occlusion of the LAA to identify correct placement and potential leaks. We recommend incorporating CMR in future clinical studies to evaluate new device types.</p

Total length 100–130 mm long. Color of adults uniformly reddish black to greenish black. Pectinal teeth number 12–15 in both sexes. Male with slightly narrower chela than female; chela length/ width ratio 1.79–1.94 in males, 1.69 in female. Chela hirsute, lobiform, without carinae on dorsoexternal surface, but may bear rows of granules. Chela length/ width ratio 1.8–2.0 in adults. Entire manus covered by rounded granules that may merge and appear as rows. Pedipalp patella without pronounced internal tubercle. Carapace smooth, glossy medially, with granules at margins. Second metasomal segment approximately as long as wide. Fifth segment of metasoma about as long pedipalp femur, fourth segment of metasoma shorter than pedipalp femur. Dorsal and dorsolateral carinae of metasomal segments granulated. Vesicle of telson usually longer than aculeus. Spination formula of tarsomeres II of legs: 3-4/4-6: 4/4-5: 4/5-6: 4/5-7. COMMENTS. Palamnaeus serratus Pocock, 1900 was synonymized with H. indus by Couzijn (1981: 121). The first author (Kovařík, 2004: 17 and Kovařík, 2009: 38) accepted the synonymy, whereas Tikader & Bastawade (1983: 555) considered H. serratus a valid species. Examination of additional specimens collected during the Sri Lankan expedition of 2015 convinced us that H. serratus is in fact a valid species. Pocock (1900: 86) differentiated H. serratus and H. indus as follows: 1) dorsal and dorsolateral carinae of metasomal segments granulated in H. serratus (Fig. 574), smooth in H. indus (Fig. 573). We found other minor differences: 2) sexual dimorphism in proportions of pedipalps not noticeable in H. indus, male with slightly narrower chela than female in H. serratus (chela length to width ratio 1.79–1.94 in males, 1.69 in the females); 3) carapace smooth and glossy, only occasionally with granules at margins in H. indus (Figs. 486–487); carapace smooth and glossy medially, always with more granules at margins in H. serratus (Figs. 516–517); 4) spination formula of tarsomeres II of legs: 3/4: 2-4/3-4: 4/4-5: 4/ 5 in H. indus; 3-4/4-6: 4/4-5: 4/5-6: 4/ 5-7 in H. serratus. The distribution of H. serratus was previously unknown, as the type locality was imprecise and the holotype male was the only known specimen. We collected additional specimens at localities cited here as 15CP (Fig. 594) and 15CQ (Fig. 595). Our data suggest that H. serratus is distributed in the southern part, and H. indus in the central part of Sri Lanka (Fig. 15). DISTRIBUTION.

Pluripotent stem cells for the study of early human embryology
No full textForty years have passed since the first pluripotent stem cells (PSCs), mouse embryonic stem cells (ESCs), were established. Since then, several PSCs have been reported, including human ESCs in 1998, mouse epiblast stem cells (EpiSCs) in 2007, induced PSCs (iPSCs) in 2006 and 2007, and naïve human PSCs in 2014. Naïve PSCs are thought to correspond to pre-implantation epiblast cells, whereas conventional (or primed) human PSCs correspond to post-implantation epiblast cells. Thus, naïve and primed PSCs are classified by their developmental stages and have stage-specific characteristics, despite sharing the common feature of pluripotency. In this review, we discuss the current status of PSCs and their use to model human peri-implantation development
