Macrobrachium malayanum Cai & Naiyanetr & Ng 2004
No full textMacrobrachium malayanum (Roux, 1934) Palaemon (Macrobrachium) pilimanus malayanus Roux, 1934: 32 [type locality: Lasah, Plus valley, Perak, Malaysia]. Macrobrachium geron Holthuis, 1950: 258, figure 52 [type locality: Banka island off Sumatra, Indonesia]; Holthuis, 1980: 91; Johnson, 1961: 57. Macrobrachium malayanum: Chong and Khoo, 1987b: 903; Ng and Choy, 1990: 13; Ng, 1992: 793. Material examined South Thailand. Two ovigerous XX, cl 12.0– 14.3 mm, eggs with eye spot, 1.3× 0.9 mm, (ZRC 2000.2645), Narathiwat Province, Nam Tok Sipo, downstream area, 6°16.06∞N, 101°38.65∞E, coll. H. H. Tan et al., 24 October 1998. Diagnosis Rostrum straight, reaching to or slightly beyond end of scaphocerite; rostral formula: 3–4+5–8/3–6 (mode 3–4). Male second pereiopods unequal in length, dissimilar in form; carpus shorter than merus and chela, fingers shorter than palm; two teeth present on cutting edges of fingers, with two to three smaller ones posterior of proximal large teeth; palm inflated; entire chela of large leg covered with dense carpet of soft, short velvety pubescence; small spinules present on surface of palm; movable spine on uropodal diaeresis longer than outer angle. Ovigerous females with eggs 1.3× 0.9 mm in diameter. Remarks Only two ovigerous Thai specimens were available. The specimens agree well with the description by Chong and Khoo (1987b). This is the northernmost record for M. malayanum, and also a new record for Thailand. Macrobrachium malayanum is distributed throughout the Malay Peninsula, Borneo and Sumatra (Roux, 1934; Holthuis, 1950; Chong and Khoo, 1987a; Ng and Choy, 1990; Ng, 1992), and its presence in southern Thailand is not unexpected.Published as part of Cai, Y., Naiyanetr, P. & Ng, P.

Figure 1: Serelaxin Temporarily Decreases Blood Pressure in the Angiotensin II/L-NG-Nitroarginine Methyl Ester Experimental Model
No full text(A) In the Chronic:post-treatment study, telemeters were implanted on day 7. Blood pressure (BP) was recorded at baseline and throughout the duration of the experiment. In each experiment, angiotensin II (AngII) (800 ng/kg/min)/L-NG-nitroarginine methyl ester (L-NAME) (30 mg/kg/day in drinking water) treatment began at day 0. On day 7, mice were randomized to serelaxin or vehicle infusion by 3-day osmotic pump. Mice were sacrificed, and cardiac and vascular parameters were measured on day 9 in the Acute:on-treatment groups and on day 28 in the Chronic:post-treatment groups. (B) Telemetric average 24-h systolic blood pressure on day 0 and daily from day 7 to day 28. (C) Systolic blood pressure changes from baseline to day 28 during AngII/L-NAME. *p = 0.028.

Male pleonal somite 3 widest, somite 4 abruptly narrowed distally, lateral margins of somites 3–5 clearly concave. G1 short, almost straight, stout, narrowed medially, distal end with relatively narrow, anterolaterally directed corneous process.

Low, 1 Aug.1992.</p> <p> <i>Diagnosis. –</i> Dorsal surface of carapace pitted, ca. 1.11-1.16 times as long as broad, behind strongly convex front. Front divided into 3 teeth: median one prominently larger than lateral ones, tip bluntly rounded; lateral teeth low, subtriangular. Hepatic region protruding, with fine granules. Lateral margins of carapace with bead-like granules. Posterior carapace margin slightly convex, with minute beadlike granules. Surface of third maxilliped pitted, margins convex, serrulate; exopod 3 times as long as broad (measured along inner border); merus sharply triangular, twice as long as broad, inner distal margin granulated; ischium relatively short. Chelipeds symmetrical; merus cylindrical, 3 times as long as broad, dorsal surface of basal half with 2 longitudinal rows of pearl-like granules, borders with granules, granules of basal two-thirds coarser than those of distal one-third; dorsal surface of carpus with fine granules; palm slender, twice as long as broad, covered with fine granules; movable finger shorter than palm, cutting edges of both fingers with indistinct teeth, basal half unarmed, forming relatively large gape when closed. Ambulatory legs slender, smooth; first pair longest, last pair shortest. Surface of male abdomen pitted, with 5 free segments; segments 3-5 fused, base of both sides bluntly rounded, gradually convergent to distal part, median surface unarmed; segment 1 transversely narrow; segment 2 3 times as long as first segment; segment 6 longer than broad; telson triangular.</p> <p> <i>Etymology. –</i> The name is derived from the Latin “punctum” for small hole, alluding to the numerous small pits on the carapace.</p> <p> <i> <i>Remarks. -</i> Pseudophilyra punctulata</i> , new species, closely resembles <i>P. intermedia</i> Ihle, 1918, but differs in that the anterior surface of the carapace does not have a discernible median beaded ridge (vs. present), the median frontal tooth is relatively more acute, the lateral and posterior margins of the carapace have coarser granules, the exopod of the third maxilliped is proportionately broader with the outer border serrated and the inner distal margin of the merus is granulated (vs. inner distal margin of the merus unarmed), the surface of fused male abdominal segments 3-5 does not have a median tooth (vs. distinctly present), and the distal half of the cutting edges of both fingers have only weakly developed teeth, with the basal half leaving a larger gape when the fingers are closed (vs. more developed teeth with only weak gape) (fide Ihle, 1918: 269, Fig. 140; Komatsu & Takeda, 2000: 275, Figs. 4 f-l, 5A).</p> <p> <i>Pseudophilyra intermedia</i> was described the Banda Sea (Indonesia) (Ihle, 1918) and has also been reported from Japan (Komatsu & Takeda, 2000). Komatsu & Takeda (2000: 278) also discussed the close affinities of <i>P. intermedia</i> with the allied <i>P. tridentata</i> Miers, 1879. The differences noted here between <i>P. punctulata</i> and <i>P. intermedia</i> are also applicable for <i>P. tridentata</i>, except that the frontal median tooth of the latter species is even more pronounced.</p>Published as part of <i>H. - L., Chen & Ng, Peter K.
