Abstract:
A new species (Microcharacidium bombioides sp. nov.) of the genus Microcharacidium Buckup, 1993 is described from the Rio Negro, Rio Trombetas, Rio Tapajós, tributaries of the Rio Madeira, and the middle Rio Amazonas. The new species is promptly distinguished from all congeners (Microcharacidium eleotrioides (Géry, 1960), Microcharacidium gnomus Buckup, 1993, and Microcharacidium weitzmani Buckup, 1993) by the presence of 12 circumpeduncular scales, 19 precaudal vertebrae, and 7 dark bars on the flanks connected to their contralateral parts both dorsally and ventrally; 2 short, dark suborbital stripes; all teeth on both jaws conical; 10–11 total dorsal-fin rays; and 3–4 perforated lateral line scales. An updated identification key for the genus is provided and the affinities of the new species with other Microcharacidium are discussed.

Abstract:
Two new species of Portanus Ball, 1932 are described and illustrated from Brazil. P. hastatus sp. nov. from Ceará State, can be recognized by its acute pygofer apex and aedeagus with pair of apical processes directed dorsally. Portanus phoenicius sp. nov. from Piauí State, can be recognized by its rounded pygofer lobe with dorsal tooth turned inwardly, aedeagus apex with pair of elongate processes and pair of rounded flanges directed ventrally. Portanus boliviensis is newly recorded from Brazil. These findings double the number of species of Portanini recorded from Northeastern Brazil.

Abstract:
Dorsal closure is an essential stage of Drosophila embryogenesis and is a powerful model system for morphogenesis, wound healing, and tissue biomechanics. During closure, two flanks of lateral epidermis close an eye-shaped dorsal opening that is filled with amnioserosa. The two flanks of lateral epidermis are zipped together at each canthus (“corner” of the eye). Actomyosin-rich purse strings are localized at each of the two leading edges of lateral epidermis (“lids” of the eye). Here we report that each purse string indents the dorsal surface at each leading edge. The amnioserosa tissue bulges outward during the early-to-mid stages of closure to form a remarkably smooth, asymmetric dome indicative of an isotropic and uniform surface tension. Internal pressure of the embryo and tissue elastic properties help to shape the dorsal surface.

Abstract:
Cnemaspis flaviventralis, a new species of day gecko, is described from the forests of Amboli, Sindhudurg District, Maharashtra State, northern Western Ghats, India. The new species was previously confused with the sympatric species Cnemaspis girii, C. indraneildasii, C. kolhapurensis and C. goaensis. It is distinguished from C. giri by having spine-like tubercles on flanks, granular dorsal scales intermixed with large, depressed, slightly keeled scales (vs. lack of spine-like tubercles on flanks, granular dorsal scales, intermixed with large smooth scales); from C. indraneildasii by having dorsal scales heterogeneous (vs. homogenous), lacking a series of enlarged median sub-caudal scales, and 28–29 (vs. 20) ventral scales across mid-body; from C. kolhapurensis by having heterogeneous (vs. homogenous) dorsal scalation, lacking spine-like tubercles on flanks and lacking pre-cloacal pores (vs. 24–28 pre-cloacal-femoral pores); and from C. goaensis by lacking pre-cloacal pores and lacking a series of enlarged median sub-caudal scales. We further provide partial mitochondrial 16S rRNA gene sequences for the new species and for the sympatric species C. girii, C. kolhapurensis and C. goaensis, and show that the new species is genetically distinct.

Abstract:
Egg capsules of Atlantoraja cyclophora and A. platana are asymmetrical, dorsally convex and ventrally flat, with longitudinally striated faces. Those of other rajoid genera occurring in Cassino Beach (Rio Grande do Sul State, Brazil), Psammobatis, Sympterygia and Rioraja, are equally convex in lateral view, and have smooth faces. In Atlantoraja the egg capsules are laterally keeled while in Sympterygia a lateral flange exists. Mean egg capsule length and width are 68 and 39 mm in A. cyclophora, and 69 and 45 mm in A. platana. Egg capsules of A. platana are significantly wider than those of A. cyclophora with anterior and posterior horns significantly longer. The outline of the velum is convex in dorsal view in A. cyclophora and slightly convex in A. platana.

Full text
Abstract:
During a recent ichthyological survey in Chapada Diamantina, Estado da Bahia, Brazil, a new, very distinctive Aspidoras was discovered in tributaries of the upper rio Paraguaçu. The new taxon differs from its congeners mainly in having: a poorly-developed pigmentation pattern, restricted to minute scattered blotches on dorsal region of head and body, but grouped in small, irregular blotches along the lateral body plate junction; four or five caudal vertebra, anterior to compound caudal centrum, with neural and haemal spines placed posteriorly, close to post-zygapophyses; and post-zygapophyses of the precaudal vertebrae without dorsal expansions connected with their respective neural spines. The new species shares with Aspidoras velites dorsolateral body plates not touching their counterparts dorsally, and infraorbital bones with reduced flanges that are restricted to the latero-sensory canal. Both of these are considered reductive character states, probably indicating a paedomorphic condition to both species. The new species is also compared to Aspidoras maculosus, a congener which bears the most similar color pattern and is geographically closest to the new species.

Full text
Abstract:
Les échantillons étudiés proviennent de carottages effectués lors de la campagne en mer Ticoflux 2 au large de la côte ouest du Costa Rica, en 2002. Ils ont été prélevés sur les pentes nord-ouest du « Mont Dorado » : une zone où des décharges diffuses de fluides de faible température ont été localisées. Nos données ont été focalisées sur la carotte GC50, composée de boues hémipélagiques altérées présentant des argiles, des zéolites, localement des oxydes Fe/Mn, ainsi que des phosphates.
La caractérisation minéralogique (DRX, MEB, MET-EDX) et chimique (majeurs, traces, terres rares) des nouvelles phases minérales formées in situ dans le sédiment GC50 a permis de mettre en évidence deux phases d'altération. La première phase consiste en un processus de diagenèse précoce. La deuxième phase d'altération engendre la précipitation d'apatites et d'oxydes Mn/Fe essentiellement localisés près de l'interface sédiment-basalte. Les données de la géochimie isotopique du strontium et du néodyme, ainsi que la distribution des spectres des Terres Rares, ont permis de préciser la nature du fluide à l'origine de la seconde phase d'altération. Ces marqueurs géochimiques suggèrent la décharge d'un fluide hydrothermal de basse température ayant très peu interagit avec le basalte lors de sa circulation dans la croûte.
Une étude plus poussée (EXAFS, METHR) sur les échantillons riches en oxydes Mn/Fe a permis de proposer un modèle de formation et d'évolution des oxydes Mn, dans ce contexte hydrothermal hors axe. Ce modèle démontre que la formation de todorokite (tectomanganate), minéral ubiquiste en milieu marin, nécessite la présence d'un précurseur, ici la vernadite (phyllomanganate).

Abstract:
Introdução: Os autores estudaram o efeito da toxina botulinica tipo A (BontA) na viabilidade de retalhos cutâneos em ratos saudáveis, expostos à fumaça de cigarro e diabéticos. Material e métodos: Foram avaliados 90 ratos Wistar machos com peso variando entre 170 a 469 g (média 282,56 g). Esses animais foram divididos em seis grupos: saudáveis com aplicação de solução fisiológica (SF) (C1), saudáveis com aplicação de Toxina botulínica tipo A (BontA) (C2), expostos à fumaça de cigarro com aplicação de SF (T1), expostos à fumaça de cigarro com aplicação de BontA (T2), diabéticos com aplicação de SF (D1) e diabéticos com aplicação de BontA (D2). Os ratos pertencentes ao grupo exposição à fumaça de cigarro foram expostos por um período de 28 dias duas vezes ao dia ininterruptamente. O Diabete foi induzido pela injeção, intravenosa de estreptozotocina (55 mg/Kg) 56 dias antes do início dos procedimentos. Sete dias antes da realização do retalho cutâneo foi injetado ao longo do retalho, BontA (20u) ou SF 0,9%, de acordo com o subgrupo ao qual o animal foi alocado. Foi realizado procedimento para obtenção de retalho cutâneo dorsal (3x10 cm) e no sétimo pósoperatório os retalhos foram fotografados e a seguir realizada eutanásia. As fotografias foram digitalizadas e analisadas pelo programa Image J®, através do qual foi aferido área viável e área total. Através do programa Excel® foi calculado a razão da área viável/área total dos retalhos dorsais dos animais. A seguir foi coletado amostra de tecido com dimensões de 0,4x5 cm, para análise das arteríolas (lúmen, diâmetro, espessura média da parede arteriolar e razão do lúmen/espessura média), segundo método de estereologia. Resultados: A razão de área viável/área total apresentou diferença significativa no grupo controle tratado com BontA, (C2 x C1; 0,9 ± 0,1 vs 0,67 ± 0,15, p= 0,001). O mesmo comportamento foi observado no grupo diabete que recebeu a aplicação de BontA (D2 x D1 groups; 0,97±0,2 vs 0,61±0,24, p=0,018). O grupo exposto à fumaça de cigarro não apresentou diferença estatística. À estereologia, não houve diferença da avaliação miscrocópica dos grupos controle e expostos à fumaça de cigarro. O grupo diabete mostrou diferença estatística nos animais que receberam a aplicação de BontA em relação os que receberam SF, lúmen (p=0,004), diâmetro (p=0,05), razão lúmen/espessura média (p=0,003). Conclusão: a toxina botulínica tipo A aumentou a viabilidade do retalho cutâneo dorsal em ratos sadios e diabéticos no sétimo pós-operatório. Houve aumento do lúmen, diâmetro, razão do lúmen/ espessura média dos retalhos cutâneos dos animais diabéticos
Background: Botulinum toxin A (BoNTA) might be effective in reducing skin flap necrosis. This study investigated BoNTA influence on skin flap viability in healthy, tobacco-exposed and diabetic rats. Methods: Ninety male Wistar rats (170 a 469 g) were randomly divided into six groups: control+saline solution (C1), control+BoNTA (C2), tobacco-exposed+saline solution (T1), tobacco-exposed+BoNTA (T2) diabetes+saline solution (D1) and diabetes+BoNTA (D2). A dorsal random skin flap (3 × 10 cm) was performed on each rat. Total flap and necrosis areas were measured through macroscopic evaluation using ImageJ® software. Survival area /total area ratio was calculated. After euthanasia skin flap samples were collected for stereological assessment. Lumen, diameter, wall thickness, and lumen/wall thickness ratio of all arterioles along the panniculus carnosus were measured. Results: Survival flap area/total flap area ratio increased in control group with BoNTA injection compared with control animals injected with saline solution (C2 x C1 groups; 0.9 ± 0.1 vs 0.67 ± 0.15, p= 0.001). A similar result was found in the diabetic group injected with BontA when compared with the diabetic group injected with saline solution (D2 x D1 groups; 0.97±0.2 vs 0.61±0.24, p=0.018). We did not observe any difference in skin flap viability in the tobacco-exposed groups (T1 x T2 groups; 0.64± 0.21 vs 0.74±0.24, p=0.871)). Lumen(p=0.004), diameter(p=0.05) and lumen/wall thickness ratio (p=0.003) were increased in diabetic BoNTA-treated animals compared with diabetic animals injected with saline solution. This effect was not observed in control groups or in the tobacco-exposed groups. Conclusion: BoNTA increased skin flap viability in control and diabetic rats on the seventh postoperative day and resulted in increased lumen, diameter, and lumen/wall thickness ratio in the diabetic animals

Abstract:
Andaman and Nicobar Islands are endowed with immaculate flora and fauna biodiversity. Among the indigenous livestock species, pig occupies 27.26%. Andaman and Nicobar Islands have three different categories of domestic pig groups/breeds. Andaman Local pig is prevalent in Andaman group of Islands (South, Middle and North Andaman); Nicobari pig is in Nicobar group of Islands and long snouted Little Andaman wild pig (Schedule II animal under Forest Act, India). Other than the indigenous pigs, pure and crossbreds of Large White Yorkshire are available in Andaman and Nicobar Islands. Nicobari Pigs are reared exclusively by Nicobari tribes in Nicobar group of islands and create a well defined socio-economic-ecological status of their tribal society. Nicobari pig occupies a prominent place in custom, festivals and socio-economic status of Nicobari tribes. These Andaman local and Nicobari pigs are reared for meat purpose under free range or semi-intensive system. Nicobari pig is appeared as short, black/brownish in colour and living as a family. Andaman local pig is available in Andaman group of islands and body colour differs from rusty grey to black and brown. Neck and dorsal portion hair are long and thick whereas flank and sides hairs are shorter and thinner. Wild pig of Andaman (Sus scrofa andamanensis) is a most endangered porcine species of Andaman and Nicobar islands. Jarawa tribes in Andaman Islands prefer this wild pig as a good protein source. It is black in colour, short legged, small to medium sized and a prolific breeder. Litter size varies from 4 to 7 numbers. Another pig group is crossbred, cross between Large White Yorkshire and Andaman local or Nicobari pig. Crossbred pigs are light brown to complete white with different lines of blackish colour. This breed exhibits early maturity, high growth rate and fecundity. The Nicobari pig has high prolificacy as litter size is ranging from 8 to 10 numbers with good mothering ability and body weight of matured pig differs from 115 to 130 kg. Moreover, this crossbred is adapted highly to the local tropical humid environmental conditions and also can adjust with locally available feed resources on the different agricultural produces. This is highly suitable for commercial production of pork in this Andaman and Nicobar islands. However, the domestic pig breeds need to be protected and be conserved in this Andaman and Nicobar group of Islands.

Abstract:
Cardiac c-looping is an important developmental phase, as the initially straight heart tube (HT) is transformed into a c-shaped tube. Looping consists of two distinct processes: ventral bending, which is likely driven by actin polymerization, and dextral torsion, which is likely due to external forces. These forces are applied by a membrane enveloping the ventral side of the heart, the splanchnopleure (SPL, Fig. 2A) and a pair of atria that flank the caudal end of the heart tube (HT, Fig 1A). In particular, the atria provide the initial push, biasing the HT towards the right while the SPL applies a ventrally directed force, which causes the HT to rotate using the dorsal mesocardium (DM, Fig. 2A) as a pivot (the DM attaches the dorsal length of the heart to the body of the embryo).
