Monographic Revision Of The Genus Aegidinus Arrow (1904) And Generic Phylogeny Of The World Orphninae (Coleoptera: Scarabaeidae: Orphninae), Julia Colby

Insecta Mundi

A taxonomic revision was performed on the New World scarabaeoid genus Aegidinus Arrow (Coleoptera: Scarabaeidae: Orphninae). Twelve new species and three previously described species are included in the revision. Keys to New World genera, species of the genus Aegidinus, and distribution maps are provided. Phylogenetic analyses of the world genera of the Orphninae were conducted using 30 adult, morphological characters from representatives of 13 of the 14 genera and three out-group taxa. The subfamily Orphninae is a strongly supported monophyletic group (bootstrap support 88-90%) with respect to the chosen out-group. Characters that support the Orphninae are: mandibles not sickle …


Structure And Functions Of Keratin Proteins In Simple, Stratified, Keratinized And Cornified Epithelia, Hermann H. Bragulla, Dominique G. Homberger May 2009

Structure And Functions Of Keratin Proteins In Simple, Stratified, Keratinized And Cornified Epithelia, Hermann H. Bragulla, Dominique G. Homberger

Faculty Publications

Historically, the term 'keratin' stood for all of the proteins extracted from skin modifications, such as horns, claws and hooves. Subsequently, it was realized that this keratin is actually a mixture of keratins, keratin filament-associated proteins and other proteins, such as enzymes. Keratins were then defined as certain filament-forming proteins with specific physicochemical properties and extracted from the cornified layer of the epidermis, whereas those filament-forming proteins that were extracted from the living layers of the epidermis were grouped as 'prekeratins' or 'cytokeratins'. Currently, the term 'keratin' covers all intermediate filament-forming proteins with specific physicochemical properties and produced in any …


Apicomplexan Parasites Co-Opt Host Calpains To Facilitate Their Escape From Infected Cells, Rajesh Chandramohanadas, Paul H. Davis, Daniel P. Beiting, Michael B. Harbut, Claire Darling, Geetha Velmourougane, Ming Yeh Lee, Peter A. Greer, David S. Roos, Doron C. Greenbaum May 2009

Apicomplexan Parasites Co-Opt Host Calpains To Facilitate Their Escape From Infected Cells, Rajesh Chandramohanadas, Paul H. Davis, Daniel P. Beiting, Michael B. Harbut, Claire Darling, Geetha Velmourougane, Ming Yeh Lee, Peter A. Greer, David S. Roos, Doron C. Greenbaum

Biology Faculty Publications

Apicomplexan parasites, including Plasmodium falciparum and Toxoplasma gondii (the causative agents of malaria and toxoplasmosis, respectively), are responsible for considerable morbidity and mortality worldwide. These pathogenic protozoa replicate within an intracellular vacuole inside of infected host cells, from which they must escape to initiate a new lytic cycle. By integrating cell biological, pharmacological, and genetic approaches, we provide evidence that both Plasmodium and Toxoplasma hijack host cell calpain proteases to facilitate parasite egress. Immunodepletion or inhibition of calpain-1 in hypotonically lysed and resealed erythrocytes prevented the escape of P. falciparum parasites, which was restored by adding purified calpain-1. Similarly, efficient …

Electron Transport And Sensor Characteristics Of Tin Dioxide Based Nanocrystalline Materials, Allen Chaparadza May 2009

Electron Transport And Sensor Characteristics Of Tin Dioxide Based Nanocrystalline Materials, Allen Chaparadza

Dissertations and Theses

Wide band gap, transparent semiconductor Sn02 is an n-type conductor and is widely used as a sensor material as well as transparent electrode material e.g. in solar cells and flat panel displays. Recent discovery of p-type doping with Li has opened exciting possibilities in new classes of sensors and transparent nanoelectronic devices. Li-doping in SnO2 nanoparticles was explored through a gel-sol method of synthesis to examine the influence of reaction conditions such as pH, dopant concentration, and calcination temperature. The Li doping in nanoparticles was characterized using nuclear reaction analysis and the nanostructure with high-resolution electron transmission microscopy …

Coexistence And Transition Between Cassie And Wenzel State On Pillared Hydrophobic Surface, Takahiro Koishi, Kenji Yasuoka, Shigenori Fujikawa, Toshikazu Ebisuzaki, Xiao Cheng Zeng

Xiao Cheng Zeng Publications

Water droplets on rugged hydrophobic surfaces typically exhibit one of the following two states: (i) the Wenzel state [Wenzel RN (1936) Ind Eng Chem 28:988–994] in which water droplets are in full contact with the rugged surface (referred as the wetted contact) or (ii) the Cassie state [Cassie, ABD, Baxter S (1944) Trans Faraday Soc 40:546–551] in which water droplets are in contact with peaks of the rugged surface as well as the “air pockets” trapped between surface grooves (the composite contact). Here, we show large-scale molecular dynamics simulation of transition between Wenzel state and Cassie state of water droplets …

Minimum Criteria For Dna Damage-Induced Phase Advances In Circadian Rhythms, Christian I. Hong, Judit Zámborszky, Attila Csikász-Nagy May 2009

Minimum Criteria For Dna Damage-Induced Phase Advances In Circadian Rhythms, Christian I. Hong, Judit Zámborszky, Attila Csikász-Nagy

Dartmouth Scholarship

Robust oscillatory behaviors are common features of circadian and cell cycle rhythms. These cyclic processes, however, behave distinctively in terms of their periods and phases in response to external influences such as light, temperature, nutrients, etc. Nevertheless, several links have been found between these two oscillators. Cell division cycles gated by the circadian clock have been observed since the late 1950s. On the other hand, ionizing radiation (IR) treatments cause cells to undergo a DNA damage response, which leads to phase shifts (mostly advances) in circadian rhythms. Circadian gating of the cell cycle can be attributed to the cell cycle …

The Complexities And Opportunities Of Examining Scale In Ecology – With Application To Grassland Management, Skadi Von Reis May 2009

The Complexities And Opportunities Of Examining Scale In Ecology – With Application To Grassland Management, Skadi Von Reis

Macalester Reviews in Biogeography

Understanding the way in which biodiversity is created and maintained is the fundamental goal of applied ecology. In order to comprehend how diversity is distributed and isolate the factors contributing to diversity, multiple scales of study must be considered. Studies which base their conclusions on an isolated snapshot of an ecological system find their results challenged by considering both historical and spatial scales. The question of scale: its definition, the relevant scale at which biological processes produce observable patterns, the translation from small to large scales and the theoretical and technological complications scale presents, remain contentious issues in ecology. This …


Biogeography Of Microorganisms Inhabiting Marine Sponges, Suzy C. Szumowski May 2009

Biogeography Of Microorganisms Inhabiting Marine Sponges, Suzy C. Szumowski

Macalester Reviews in Biogeography

Sponge-associated microorganisms are an intriguing system for the consideration of biogeographic patterns due to complications arising from their small size and their symbiotic relationship with sponges. Whether or not microorganisms are capable of exhibiting biogeographic patterns is a topic of heated debate in the literature. Recent studies utilizing new identification techniques have revealed an astonishing amount of diversity and spatiotemporal stability in microorganism communities. Case studies outlined in this paper suggest that some sponge-associated microorganisms represent monophyletic groups that have evolved speciesspecific associations with their hosts. The biogeography of these organisms is receiving increasing attention because they are one of …


A Review Of Endemic Species In The Eastern Arc Afromontane Region: Importance, Inferences, And Conservation, Carl Skarbek May 2009

A Review Of Endemic Species In The Eastern Arc Afromontane Region: Importance, Inferences, And Conservation, Carl Skarbek

Macalester Reviews in Biogeography

The Eastern Arc mountain region has been identified as one of the top 25 biodiversity “hotspots” worldwide, and contains a large proportion of endemic species. The endemic species are invaluable resources. This review paper will explore and discuss the possible theories behind the high rate of endemism. The importance of these endemics to local peoples and to the greater global community has been studied thoroughly, and these results are presented in further detail in this paper. The Eastern Arc is also facing many problems that are threatening the biodiversity and rare endemic species of this region. Human expansion into natural …


Leishmaniasis: A Review Of The Disease And The Debate Over The Origin And Dispersal Of The Causaitive Parasite Leishmania, Molly Macmorris-Adix May 2009

Leishmaniasis: A Review Of The Disease And The Debate Over The Origin And Dispersal Of The Causaitive Parasite Leishmania, Molly Macmorris-Adix

Macalester Reviews in Biogeography

The vector borne disease Leishmaniasis, caused by the Leishmania parasite, is estimated to affect the lives of 12 million people. Manifesting itself into three different clinical forms that center on disfiguring sores and enlargement of several organs, Leishmaniasis is a devastating disease impairing economic productivity and impeding socioeconomic development. The complex life cycle of this parasite, involving a host, vector, and reservoir, has played a major role in defining the dispersal and prevalence of this disease on a global level. The prevalence of Leishmaniasis is highly concentrated due to the close relationship of this parasite and its single vector (the …


The Biogeography Of Plant Domestication, Alese M. Colehour May 2009

The Biogeography Of Plant Domestication, Alese M. Colehour

Macalester Reviews in Biogeography

Ranging between 11,000 and 4,000 years ago, several independent origins of agriculture appeared, though scholars disagree on exactly how many. This period, known as the “Neolithic Revolution” or the “Origins of Agriculture,” marks the initial emergence of food production economies. Archaeologists and biologists have worked alongside one another, often using a biogeographical approach, to investigate the origins of useful species, their range expansion, and genetic evolution through analyzing remains found at excavation sites around the world. Plant communities influence patterns in human behaviors and by understanding trends in biogeography we can begin to answer questions such as: Why did plant …

Reducing Stillbirths: Behavioural And Nutritional Interventions Before And During Pregnancy., Mohammad Yawar Yakoob, Esme V Menezes, Tanya Soomro, Rachel A Haws, Gary L Darmstadt, Zulfiqar Ahmed Bhutta May 2009

Reducing Stillbirths: Behavioural And Nutritional Interventions Before And During Pregnancy., Mohammad Yawar Yakoob, Esme V Menezes, Tanya Soomro, Rachel A Haws, Gary L Darmstadt, Zulfiqar Ahmed Bhutta

Woman and Child Health

Background:The vast majority of global stillbirths occur in low- and middle-income countries, and in many settings, the majority of stillbirths occur antenatally, prior to the onset of labour. Poor nutritional status, lack of antenatal care and a number of behaviours increase women's risk of stillbirth in many resource-poor settings. Interventions to reduce these risks could reduce the resulting burden of stillbirths, but the evidence for the impact of such interventions has not yet been comprehensively evaluated.

Methods:

This second paper of a systematic review of interventions that could plausibly impact stillbirth rates covers 12 different interventions relating to behavioural …

Reducing Stillbirths: Prevention And Management Of Medical Disorders And Infections During Pregnancy., Esme V Menezes, Mohammad Yawar Yakoob, Tanya Soomro, Rachel A Haws, Gary L Darmstadt, Zulfiqar Ahmed Bhutta

Woman and Child Health

Background:An estimated two-thirds of the world's 3.2 million stillbirths occur antenatally, prior to labour, and are often overlooked in policy and programs. Poorly recognised, untreated or inadequately treated maternal infections such as syphilis and malaria, and maternal conditions including hypertensive disorders, are known risk factors for stillbirth.

Methods:

We undertook a systematic review of the evidence for 16 antenatal interventions with the potential to prevent stillbirths. We searched a range of sources including PubMed and the Cochrane Library. For interventions with prior Cochrane reviews, we conducted additional meta-analyses including eligible newer randomised controlled trials following the Cochrane protocol. We …
