Abstract
Aims: Tuberculous infection of the thoracic cage is rare and is difficult to discern clinically or on radiographs. This study aims to describe the common sites and the imaging appearances of chest wall tuberculosis. Materials and Methods: A retrospective review of the clinical and imaging records of 12 confirmed cases of thoracic cage tuberculosis (excluding that of the spine), seen over the last 7 years, was performed. Imaging studies available included radiographs, ultrasonographies (USGs), and computed tomography (CT) scans. Pathological confirmation was obtained in all cases. Results: All patients had clinical signs and symptoms localized to the site of involvement, whether it was the sternum, sternoclavicular joints, or ribs. CT scan revealed sternal destruction in three patients and osteolytic lesions with sclerosis of the articular surfaces of the sternoclavicular joints in two patients. In five patients with rib lesions, USG elegantly demonstrated the bone destruction underlying the cold abscess. All cases were confirmed to be of tuberculous origin by pathology studies of the aspirated/curetted material, obtained by CT / USG guidance. Conclusions: Tuberculous etiology should be considered for patients presenting with atypical sites of skeletal inflammation. CT scan plays an important role in the evaluation of these patients. However, the use of USG for demonstrating rib destruction in a chest wall cold abscess has so far been under-emphasized, as has been the role of CT and USG guided aspiration in confirming the aetiology.

Pictorial essay: Complications of a swallowed fish bone
Authors: Bathla Girish , Teo Lynette LS , Dhanda Sunita 
Published: January 2011

AbstractUnintentional ingestion of a fishbone (FB) is common, especially in populations with a high consumption of seafood. In most instances, the ingested FB passes uneventfully through the gastrointestinal (GI) tract, usually within a week. However, in certain cases, the FB may become impacted and lead to complications. Awareness of these complications is important as patients usually present with nonspecific symptoms and could be unaware of having ingested an FB.

Use of local ecological knowledge, scientist's observations and grey literature to assess marine species at risk in a tropical eastern Pacific estuary
Authors: Castellanos‐Galindo Gustavo A. , Cantera Jaime R. , Espinosa Silvana , Mejía‐Ladino Luz Marina 
Published: January 2011

Abstract
The loss of marine biodiversity in tropical regions of the world is a major threat to human welfare. Multiple anthropogenic drivers are responsible for this situation, with complex scenarios for coastal areas in third‐world countries, where economic development often competes with conservation plans.
The International Union for the Conservation of Nature (IUCN) Red List of Threatened Species is an influential tool for setting conservation priorities at local and regional levels. The application of IUCN criteria for assessing extinction risk, however, continues to represent a major challenge in data‐poor situations present in many tropical megadiverse countries.
To overcome these difficulties, three different data sources on invertebrates and fishes present in an estuarine system representative of the tropical eastern Pacific (TEP) region (Bahía Málaga, Colombia) have been used to establish their relative local extinction risk and correlate this information with the existing IUCN Red List categories. Data sources included (1) IUCN global and national listings, (2) traditional ecological knowledge (TEK), and (3) grey literature, scientific and natural history observations.
In total, 46 threatened species were evaluated after combining the three data sources. Only 17 species were previously identified as threatened by IUCN global and national listings, whereas the remaining 29 species were classified under a threatened category after evaluating TEK, grey literature and scientific information. Some of these species are seriously threatened within the estuary because of overharvesting and habitat destruction.
Despite most of the species identified having large geographical ranges in the TEP, they may face the same threats throughout their ranges. The approach provides a useful tool to assess species extinction risk in tropical regions where resource exploitation and habitat degradation advance rapidly, making the setting of conservation priorities an urgent task.

AbstractThe essential oils of Anthospermum emirnense Baker and Anthospermum perrieri Homolle ex Puff, obtained by hydrodistillation in 0.03 and 0.02% yield, respectively, were analyzed by GC/MS. In both cases, the major constituents consisted of sesquiterpene hydrocarbons and oxygenated sesquiterpenes. The two species showed an important qualitative similarity, with 40 compounds common to A. emirnense and A. perrieri, including β‐elemene, trans‐β‐caryophyllene, caryophyllene oxide, and τ‐cadinol, which were major components in both cases. When tested for antimicrobial activity, both essential oils showed similar profiles and exhibited interesting minimal‐inhibitory‐concentration (MIC) values towards Bacillus subtilis, Chryseobacterium indologenes, Flavimonas oryzihabitans, and Yersinia enterocolitica.

AbstractBimetallic three‐dimensional amorphous mesoporous materials, Al‐Zr‐TUD‐1 materials, were synthesised by using a surfactant‐free, one‐pot procedure employing triethanolamine (TEA) as a complexing reagent. The amount of aluminium and zirconium was varied in order to study the effect of these metals on the Brønsted and Lewis acidity, as well as on the resulting catalytic activity of the material. The materials were characterised by various techniques, including elemental analysis, X‐ray diffraction, high‐resolution TEM, N2 physisorption, temperature‐programmed desorption (TPD) of NH3, and 27Al MAS NMR, XPS and FT‐IR spectroscopy using pyridine and CO as probe molecules. Al‐Zr‐TUD‐1 materials are mesoporous with surface areas ranging from 700–900 m2 g−1, an average pore size of around 4 nm and a pore volume of around 0.70 cm3 g−1. The synthesised Al‐Zr‐TUD‐1 materials were tested as catalyst materials in the Lewis acid catalysed Meerwein–Ponndorf–Verley reduction of 4‐tert‐butylcyclohexanone, the intermolecular Prins synthesis of nopol and in the intramolecular Prins cyclisation of citronellal. Although Al‐Zr‐TUD‐1 catalysts possess a lower amount of acid sites than their monometallic counterparts, according to TPD of NH3, these materials outperformed those of the monometallic Al‐TUD‐1 as well as Zr‐TUD‐1 in the Prins cyclisation of citronellal. This proves the existence of synergistic properties of Al‐Zr‐TUD‐1. Due to the intramolecular nature of the Prins cyclisation of citronellal, the hydrophilic surface of the catalyst as well as the presence of both Brønsted and Lewis acid sites synergy could be obtained with bimetallic Al‐Zr‐TUD‐1. Besides spectroscopic investigation of the active sites of the catalyst material a thorough testing of the catalyst in different types of reactions is crucial in identifying its specific active sites.
Quantitative analysis of Pac1/LIS1‐mediated dynein targeting: Implications for regulation of dynein activity in budding yeast

Published: January 2011

AbstractLIS1 is a critical regulator of dynein function during mitosis and organelle transport. Here, we investigated how Pac1, the budding yeast LIS1 homologue, regulates dynein targeting and activity during nuclear migration. We show that Pac1 and Dyn1 (dynein heavy chain) are dependent upon each other and upon Bik1 (budding yeast CLIP‐170 homologue) for plus end localization, whereas Bik1 is independent of either. Dyn1, Pac1 and Bik1 interact in vivo at the plus ends, where an excess amount of Bik1 recruits approximately equal amounts of Pac1 and Dyn1. Overexpression of Pac1 enhanced plus end targeting of Dyn1 and vice versa, while affinity‐purification of Dyn1 revealed that it exists in a complex with Pac1 in the absence of Bik1, leading us to conclude that the Pac1‐Dyn1 complex preassembles in the cytoplasm prior to loading onto Bik1‐decorated plus ends. Strikingly, we found that Pac1‐overexpression augments cortical dynein activity through a mechanism distinct from loss of She1, a negative regulator of dynein‐dynactin association. While Pac1‐overexpression enhances the frequency of cortical targeting for dynein and dynactin, the stoichiometry of these complexes remains relatively unchanged at the plus ends compared to that in wild‐type cells (∼3 dynein to 1 dynactin). Loss of She1, however, enhances dynein‐dynactin association at the plus ends and the cell cortex, resulting in an apparent 1:1 stoichiometry. Our results reveal differential regulation of cortical dynein activity by She1 and Pac1, and provide a potentially new regulatory step in the off‐loading model for dynein function. © 2011 Wiley‐Liss, Inc.
Megakaryocyte lineage‐specific class VI β‐tubulin suppresses microtubule dynamics, fragments microtubules, and blocks cell division
Authors: Yang Hailing , Ganguly Anutosh , Yin Shanghua , Cabral Fernando 
Published: January 2011

AbstractClass VI β‐tubulin (β6) is the most divergent tubulin produced in mammals and is found only in platelets and mature megakaryocytes. To determine how this unique tubulin isotype affects microtubule assembly and organization, we expressed the cDNA in tissue culture cells under the control of a tetracycline regulated promoter. The β6 coassembled with other endogenous β‐tubulin isotypes into a normal microtubule array; but once the cells entered mitosis it caused extensive fragmentation of the microtubules, disrupted the formation of the spindle apparatus, and allowed entry into G1 phase without cytokinesis to produce large multinucleated cells. The microtubule fragments persisted into subsequent cell cycles and accumulated around the membrane in a marginal band‐like appearance. The persistence of the fragments could be traced to a pronounced suppression of microtubule dynamic instability. Impairment of centrosomal nucleation also contributed to the loss of a normal microtubule cytoskeleton. Incorporation of β6 allowed microtubules to resist the effects of colcemid and maytansine, but not vinblastine or paclitaxel; however, cellular resistance to colcemid or maytansine did not occur because expression of β6 prevented cell division. The results indicate that many of the morphological features of megakaryocyte differentiation can be recapitulated in non‐hematopoietic cells by β6 expression and they provide a mechanistic basis for understanding these changes. © 2011 Wiley‐Liss, Inc.
Reptilian tooth development
Authors: Richman Joy M. , Handrigan Gregory R. 
Published: January 2011

AbstractDental patterns in vertebrates range from absence of teeth to multiple sets of teeth that are replaced throughout life. Despite this great variation, most of our understanding of tooth development is derived from studies on just a few model organisms. Here we introduce the reptile as an excellent model in which to study the molecular basis for early dental specification and, most importantly, for tooth replacement. We review recent snake studies that highlight the conserved role of Shh in marking the position of the odontogenic band. The distinctive molecular patterning of the dental lamina in the labial‐lingual and oral‐aboral axes is reviewed. We explain how these early signals help to specify the tooth‐forming and non‐tooth forming sides of the dental lamina as well as the presumptive successional lamina. Next, the simple architecture of the reptilian enamel organ is contrasted with the more complex, mammalian tooth bud and we discuss whether or not there is an enamel knot in reptilian teeth. The role of the successional lamina during tooth replacement in squamate reptiles is reviewed and we speculate on the possible formation of a vestigial, post‐permanent dentition in mammals. In support of these ideas, we present data on agamid teeth in which development of a third generation is arrested. We suggest that in diphyodont mammals, similar mechanisms may be involved in reducing tooth replacement capacity. Finally, we review the location of label‐retaining cells and suggest ways in which these putative dental epithelial stem cells contribute to continuous tooth replacement. genesis 49:247–260, 2011. © 2011 Wiley‐Liss, Inc.
Rho signaling pathway and apical constriction in the early lens placode
Authors: Borges Ricardo Moraes , Lamers Marcelo Lazzaron , Forti Fabio Luis , Santos Marinilce Fagundes dos , Yan Chao Yun Irene 
Published: January 2011

AbstractEpithelial invagination in many model systems is driven by apical cell constriction, mediated by actin and myosin II contraction regulated by GTPase activity. Here we investigate apical constriction during chick lens placode invagination. Inhibition of actin polymerization and myosin II activity by cytochalasin D or blebbistatin prevents lens invagination. To further verify if lens placode invaginate through apical constriction, we analyzed the role of Rho‐ROCK pathway. Rho GTPases expression at the apical portion of the lens placode occurs with the same dynamics as that of the cytoskeleton. Overexpression of the pan‐Rho inhibitor C3 exotoxin abolished invagination and had a strong effect on apical myosin II enrichment and a mild effect on apical actin localization. In contrast, pharmacological inhibition of ROCK activity interfered significantly with apical enrichment of both actin and myosin. These results suggest that apical constriction in lens invagination involves ROCK but apical concentration of actin and myosin are regulated through different pathways upstream of ROCK. genesis 49:368–379, 2011. © 2011 Wiley‐Liss, Inc.
