Description Two specimens were found in Sulaibikhat Bay, Kuwait, comprising 20-chaetiger anterior fragment of a small juvenile and a 70-chaetiger complete female about 16 mm long and 0.8 mm wide (MIMB 40934; Fig. 3A–B). Transverse bands of diffused black pigment present on dorsal side of up to 15 anterior chaetigers; small middorsal melanophores present from chaetigers 4−6 to chaetigers 10−12. Prostomium anteriorly weakly incised, notched or almost blunt, posteriorly extending to end of chaetiger 2 as a low caruncle. Occipital antenna present. Chaetiger 1 reduced, weakly separated from peristomium, with small notopodial and well developed neuropodial lamellae; notochaetae absent; neurochaetae comprising 1−5 very fine, hair-like capillaries. Chaetiger 5 same in size as chaetigers 4 or 6, with dorsal superior and ventral capillaries same in shape and number as those chaetae on chaetigers 4 or 6; two kinds of heavy spines arranged in a vertical slightly curved double row; noto- and neuropodial postchaetal lamellae present (Fig. 3 C−E). Anterior-row spines pennoned, with curved pointed tip, without subdistal constriction (Fig. 3F), up to 22 in a series; posterior-row spines simple falcate (Fig. 3G), up to 19 in a series. Bidentate hooded hooks in neuropodia from chaetiger 8, up to 15 in a series. Branchiae from chaetiger 7 to chaetiger 15. Pygidium flaring disc with wide dorsal gap and dorso-lateral processes (Fig. 3H–I). Glandular pouches in neuropodia from chaetiger 1, largest and paired in each neuropodium in chaetigers 6 and 7, single in other neuropodia. MG staining Intensely stained ventral and lateral sides and notopodial postchaetal lamellae of 15–16 anterior chaetigers, outer edges of branchiae (Fig. 3C); narrow transverse bands on dorsal side of branchiate chaetigers. Remarks Pseudopolydora achaeta was originally described from the South China Sea, Taiwan, as a common polychaete inhabiting tubes in soft sediments in brackish-water environments (Radashevsky & Hsieh 2000). Since then, the species was reported from Paraná and São Paulo (Brazil) (Lana et al. 2006; Radashevsky & Migotto 2006), Sea of Japan (Russia) (Zvyagintsev et al. 2011), Pacific side of Honshu Island (Japan) (Abe et al. 2014, 2016, 2019; Abe & Sato-Okoshi 2021), and from Florida (USA) (Bogantes et al. 2021). Here, for the first time, we report it for the Arabian Gulf (Kuwait). The only female had small oocytes up to 65 µm in diameter developing from chaetiger 15 onwards (Fig. 3J). The morphology of the specimens fits the diagnostic characters of P. achaeta. The same pattern of methylene green staining was observed in the type specimens of P. achaeta from Taiwan (MIMB 3401). The wide distribution of this species outside of its native area in the Northwest Pacific can be explained by unintentional human-mediated transportations of larvae with ballast water of ships, followed by successful invasions.

C*-algebras have a quantitative version of Pełczyński's property (V)
No full textsummary:A Banach space has Pełczyński's property (V) if for every Banach space every unconditionally converging operator is weakly compact. H. Pfitzner proved that -algebras have Pełczyński's property (V). In the preprint (Krulišová, (2015)) the author explores possible quantifications of the property (V) and shows that spaces for a compact Hausdorff space enjoy a quantitative version of the property (V). In this paper we generalize this result by quantifying Pfitzner's theorem. Moreover, we prove that in dual Banach spaces a quantitative version of the property (V) implies a quantitative version of the Grothendieck property
The Clinical Study of Congenital Looped/Coiled Peripapillary Retinal Vessels
No full textPurposeTo present clinical manifestations of eyes with peculiar looped/ coiled peripapillary retinal vessels. MethodsSeven patients with looped/ coiled retinal vessels on or near the optic disc were enrolled. All patients went through detailed ophthalmologic examinations and fluorescein angiography (FAG).ResultsThere were two men and five women. Patients' age ranged from 15 to 71 years (mean: 39 years). The follow-up period ranged from 3 to 74 months (average: 27 months). One patient had bilateral involvement. Five of the seven patients noticed sudden onset of floaters in one eye. The colour fundus photography revealed looped/coiled retinal vessels on or near the optic disc, and most of the vessels were arteries. Accompanied retinal, preretinal, or vitreous haemorrhage was noted in all five patients who had sudden onset of floaters. Fluorescein angiography showed no leakage from the looped/coiled retinal vessels. No specific underlying diseases were noted in any patients. Follow-up examination revealed reabsorption of haemorrhage, and no change of the abnormal vessel patterns in any eyes. ConclusionsThe peculiar fundus lesion of looped/ coiled peripapillary retinal vessels is likely a benign congenital retinal vascular anomaly that does not progress. Floaters secondary to preretinal or vitreous haemorrhage is the most frequent complaint. The prognosis is excellent.Eye (2005) 19 , 906–909. doi:10.1038/sj.eye.6701691; published online 24 September 2004 [ABSTRACT FROM AUTHOR
