Exostoma tibetana, a new glyptosternine catfish from the lower Yarlung Tsangpo River drainage in southeastern Tibet, China (Siluriformes: Sisoridae).

Exostoma tibetana, new species, is described from the lower Yarlung Tsangpo River drainage in southeastern Tibet, China. It is distinguished from congeners by having an adipose fin separate from the upper procurrent caudal-fin rays and incised at the posterior extremity of its base; the tip of the pelvic fin not reaching to the anus when adpressed; 10 branched pectoral-fin rays; and morphometric features associated with the body depth, adipose-fin base length, caudal-peduncle depth, snout length, and eye diameter. The validity of this new species was also supported by molecular phylogenetic analysis based on Cyt b gene sequences.

Two new species of Garra (Cypriniformes: Cyprinidae) from the lower Yarlung Tsangpo River drainage in southeastern Tibet, China.

Two new species of the fish genus Garra (Cypriniformes: Cyprinidae) are described from the lower Yarlung Tsangpo River drainage in southeastern Tibet, China. Garra motuoensis, a member of the proboscis species group, is primarily distinguished from the members of this group by having a prominent, quadrate, and slightly bilobed proboscis; 6-20 small to middle-sized unicuspid tubercles on the anterior region of the proboscis, some middle-sized unicuspid tubercles on the transverse lobe of the snout, and several small unicuspid tubercles on the lateral surface of snout; the anus situated slightly closer to the anal-fin origin than to the pelvic-fin origin (distance from anus to anal fin 36-46% of pelvic-anal distance); 36-37 lateral-line scales; and 12 circumpeduncular scales. Garra yajiangensis, a member of the proboscis species group, is primarily distinguished from the members of this group by having a prominent, quadrate, and slightly bilobed proboscis, covered with 2-7 middle-sized unicuspid tubercles, including two large-sized tubercles on anterior margin of each lobe; some small unicuspid tubercles on the transverse lobe and the lateral surface of snout; the anus situated substantially closer to the anal-fin origin than to the pelvic-fin origin (distance from anus to anal fin 19-24% of pelvic-anal distance); 34-36 lateral-line scales; and 12 circumpeduncular scales.

Chinese species of Walker (Hymenoptera: Eulophidae).

The Chinese species of Pediobius Walker, 1846 are treated in this paper, resulting in 34 species, of which 5 are newly described: P. bisulcatus Cao & Zhu sp. n.

Oocyte-specific deletion of N-WASP does not affect oocyte polarity, but causes failure of meiosis II completion.

Study Question: There is an unexplored physiological role of N-WASP (neural Wiskott-Aldrich syndrome protein) in oocyte maturation that prevents completion of second meiosis.

Summary Answer: In mice, N-WASP deletion did not affect oocyte polarity and asymmetric meiotic division in first meiosis, but did impair midbody formation and second meiosis completion.

What Is Known Already: N-WASP regulates actin dynamics and participates in various cell activities through the RHO-GTPase-Arp2/3 (actin-related protein 2/3 complex) pathway, and specifically the Cdc42 (cell division cycle 42)-N-WASP-Arp2/3 pathway.

Garra longchuanensis, a new cyprinid (Teleostei: Cypriniformes) from southern China.

A new species of the genus Garra is described from the Longchuan Jiang River, a tributary flowing to the Yiluowadi Jiang (Irrawaddy River) basin in Tengchong, Yunnan, South China. Garra longchuanensis is distinct from other Chinese congeners, except for G. qiaojiensis, in having 12 circumpeduncular scales, a well-developed rostral lobe with irregular distributed acanthoid tubercles, a deep groove to form a transverse lobe and a conspicuous, heavily tuberculated quadrate proboscis, and from G.

Taxonomic status of a population of Gymoncypris waddelli Regan, 1905 (Cypriniformes: Schizothoracinae) distributed in Pengqu River, Tibet, China.

Gymnocypris waddelli, a highland cold-water fish, is distributed among rivers and lakes of the southern Qinghai-Tibet Plateau. Although previously described as G. waddelli, specimens from the Pengqu River are morphologically distinguishable from those from Lake Yamzhog Yumco, which is the type locality of G.

Protein kinase A inhibitor, H89, enhances survival and clonogenicity of dissociated human embryonic stem cells through Rho-associated coiled-coil containing protein kinase (ROCK) inhibition.

Study Question: Can cell survival of dissociated human embryonic stem cells (hESCs) be increased during culture?

Summary Answer: A protein kinase A (PKA) inhibitor, H89, can significantly enhance survival and clonogenicity of dissociated hESCs without affecting their pluripotency.

What Is Known Already: hESCs are vulnerable to massive cell death upon cellular detachment and dissociation.

Study Design, Size, Duration: hESCs were dissociated into single cells and then cultured in feeder-dependent and -independent manners.

Efficient Protocol for Isolation of Rhaponticin and Rhapontigenin with Consecutive Sample Injection from Fenugreek (Trigonella foenum-graecum L.) by HSCCC.

High efficiency and less solvent consumption are the essential requirements of high-speed countercurrent chromatography (HSCCC), especially for the large-scale preparation. In this study, an efficient HSCCC strategy with consecutive sample injection was successfully developed to rapidly separate and purify rhaponticin and rhapontigenin from the seeds of the Chinese medicinal herb fenugreek (Trigonella foenum-graecum L.).
