Philander pebas Voss 2018
No full text<i>Philander pebas</i> Voss et al., 2018 <p>TYPE MATERIAL AND TYPE LOCALITY: MVZ 190343, the holotype by original designation, consists of the skin, skull, and frozen tissues of an adult male collected at Igarapé Nova Empresa (6.80° S, 70.73° W) on the left bank of the Rio Juruá, Amazonas, Brazil.</p> <p>SYNONYMS: None.</p> <p> DISTRIBUTION: As currently documented by examined specimens, <i>Philander pebas</i> occurs in eastern Ecuador (Orellana), eastern Peru (Loreto, Madre de Dios, Ucayali), and western Brazil (Acre, Amazonas), but Voss et al. (2018) speculated that the species might range throughout the <i>várzea</i> landscapes (seasonally inundated by white-water rivers) of western Amazonia, including those in southeastern Colombia, where it is still unknown.</p> <p>REMARKS: A morphological description, illustrations, comparisons with congeneric species, summary statistics for external and craniodental measurements, and analyses of mtDNA sequence data were provided by Voss et al.

Tlacuatzin Voss and Jansa 2003
No full textGenus <i>Tlacuatzin</i> Voss and Jansa, 2003 <p> TYPE SPECIES: <i>Didelphis</i> (<i>Micoureus</i>) <i>canescens</i> J.A. Allen, 1893, by original designation.</p> <p>SYNONYMS: None.</p> <p> REMARKS: See Voss and Jansa (2009) for an emended generic description. The relationships of <i>Tlacuatzin</i> within the tribe Marmosini have yet to be satisfactorily resolved, although the largest concatenated-gene dataset yet analyzed (Amador and Giannini, 2016) suggests that it is the sister group to <i>Marmosa.</i></p> <p> Arcangeli et al. (2018) recognized five species of this Mexican endemic genus based on phylogenetic analyses of sequence data from one mitochondrial gene (cytochrome <i>b</i>) and one nuclear gene (IRBP). Unfortunately, only cytochrome <i>b</i> was taxonomically informative, and taxonomic differences in morphological traits were not convincingly documented. In the absence of compelling evidence for nucleargene divergence, the following taxa are perhaps nothing more than mtDNA haplogroups; alternatively, they might be treated as subspecies. However, until relevant phenotypic analyses or additional genetic analyses are carried out, I list them here as valid species.</p>Published as part of <i>Voss, Robert S., 2022, An Annotated Checklist Of Recent Opossums (Mammalia: Didelphidae), pp. 1-77 in Bulletin of the American Museum of Natural History 2022 (455)</i> on page 30, DOI: 10.1206/0003-0090.455.1.1, <a href="http://zenodo.org/record/7161371">http://zenodo.org/record/7161371</a>

A newborn with very rare von Voss-Cherstvoy syndrome and literature review
No full textDeepak Sharma,1 Basudev Gupta,2 Sweta Shastri,3 Pradeep Sharma4 1Department of Pediatrics, Pt. Bhagwat Dayal Sharma Post Graduate Institute of Medical Sciences, Rohtak, 2Department of Pediatrics, Civil Hospital, Palwal, Haryana, 3Department of Pathology, N.K.P. Salve Medical College, Nagpur, Maharashtra, 4Department of Medicine, Mahatma Gandhi Medical College and Research Institute, Jaipur, Rajasthan, India Introduction: von Voss-Cherstvoy syndrome is a part of a group of syndromes with radial and hematologic abnormalities, and until now approximately ten cases have been reported in the literature. This syndrome is characterized by a triad of radial ray defects, occipital encephalocele, and urogenital abnormalities.Case presentation: We report a neonate from Indian ethnicity who was diagnosed with von Voss-Cherstvoy syndrome. The neonate had radial ray defect, occipital encephalocele, tetralogy of Fallot, and bilateral agenesis of kidney, ureter, and bladder. The neonate was suspected to have von Voss-Cherstvoy syndrome on the basis of clinical features, which was further confirmed by fibroblast analysis showing somatic mosaicism for del(13q).Conclusion: von Voss-Cherstvoy syndrome is a very rare syndrome that can be suspected on the basis of typical clinical features and confirmed by fibroblast analysis showing somatic mosaicism for del(13q). This adds a second case of this chromosome anomaly described in this syndrome. Keywords: von Voss-Cherstvoy syndrome, radial ray defects, occipital encephalocele, urogenital abnormalities, somatic mosaicism for del(13q
Towards discovering novel aspects of nuclear biology in the malaria parasite "Plasmodium falciparum"
No full textThe apicomplexan parasite P. falciparum continues to cause morbidity and mortality imposing a significant health and economic burden on human society. In light of antimalarial drug resistance and the lack of an effective vaccine there is an urgent need to understand the basic biology of Plasmodium parasites in much greater detail. In particular, basic nuclear processes such as those remain surprisingly unsought despite their importance in parasite survival and life cycle progression. Thus, identification and localisation of novel parasite proteins to areas of the nucleus is an important first step towards giving new insights into nuclear architecture and function. The main aim of this thesis was to compile an inventory of the nuclear proteome across the intra-erythrocytic cell cycle using high accuracy mass spectrometry coupled with bioinformatics and in vivo localisation experiments. The dataset was analysed for accuracy and retention of true nuclear proteins revealing a final list of 802 potential nuclear proteins with an estimated precision of 76%. Interestingly, the informational pool of this study was able to identify a large number of novel nuclear components including novel protein domains possibly involved in gene regulation, members of the nuclear pores, the nucleolus and the proteasome (chapter 2). Several transgenic parasite lines used for the experimental validation part of the nuclear core proteome were further investigated in more detail. One of these transgenic cell lines expresses the C-terminally tagged bromo-domain protein PF10_0328 and was investigated by co-immuoprecipitation experiments followed by LC-MS/MS to identify interacting proteins. Bromodomain proteins bind specifically to acetylated lysine residues in histone tails and are important regulators of transcription. Our results suggest that PF10_0328 acts in concert with two additional bromo-domain proteins in regulating transcription in P. falciparum (chapter 3). Further characterisation on the functional level of these three important regulators is currently ongoing in a collaborative effort. Characterisation of bromo-domain proteins could establish new intervention strategies against malaria as the recognition of acetylated histone tails by bromo-domains can be selectively prevented by small molecules. Furthermore, several proteins residing in the nuclear pores and the nucleolus of P. falciparum were used to visualise these structures in relation to chromosome end clusters based on fluorescence microscopy. We show that both structures, involved in nuclear-cytoplasmic trafficking and ribosomal biogenesis, respectively, do not appear to ‘cross-talk’ with silenced chromosome ends at the nuclear periphery of P. falciparum (chapter 4). In conclusion, I believe that my work about several aspects of gene regulation and nuclear architecture increases the understanding of the biology of this medically important pathogen and could have potential to identify new avenues for interventions against malaria
