During the General Assembly of the IAU in Beijing in 2012, at the business meeting of Commission 22 the list of 31 newly established showers was approved and next o cially accepted by the IAU. As a result, at the end of2013, the list of all established showers contained 95 items. The IAU MDC Working List included 460 meteor showers, among them 95 had pro tempore status. The List of Shower Groups contained 24 complexes, three of them had established status. Jointly, the IAU MDC shower database contained data of 579 showers.

Characterization of the defined MDC types and compilation of MDC initiation times (excel-file 19 kB)

Mud accumulates on continental shelves under a variety of environmental conditions and results in a diverse formation of mud depocenters (MDCs). Their three-dimensional architectures have been in the focus of several recent studies. Due to some terminological confusion concerning MDCs, the present study sets out to define eight individual MDC types in terms of surface sediment distribution and internal geometry. Under conditions of substantial sediment supply, prodeltas (distal zones off river deltas; triangular sheets), subaqueous deltas (disconnected from deltas by strong normal-to-shore currents; wedge-like clinoforms), and mud patches (scattered distribution) and mud blankets (widespread covers) are formed. Forced by hydrodynamic conditions, mud belts in the strict sense (detached from source; elongated bodies), and shallow-water contourite drifts (detached from source; growing normal to prevailing current direction; triangular clinoforms) develop. Controlled by local morphology, mud entrapments (in depressions, behind morphological steps) and mud wedges (triangular clinoforms growing in flow direction) are deposited. Shelf mud deposition took place (1) during early outer-shelf drowning (~14 ka), (2) after inner-shelf inundation to maximum flooding (9.5-6.5 ka), and (3) in sub-recent times (<2 ka). Subsequent expansion may be (1) concentric, in cases where the depocenter formed near the fluvial source, (2) uni-directional, extending along advective current transport paths, and (3) progradational, forming clinoforms that grow either parallel or normal to the bottom current direction. Classical mud belts may be initiated around defined nuclei, the remote sites of which are determined by seafloor morphology rather than the location of the source. From a stratigraphic perspective, mud depocenters coincide with sea-level highstand-related, shelf-wide condensed sections. They often show a conformable succession from transgressive to highstand systems tract stages.

Urethral epithelial cells are invaded by Neisseria gonorrhoeae during gonococcal infection in men. To understand further the mechanisms of gonococcal entry into host cells, we used the primary human urethral epithelial cells (PHUECs) tissue culture system recently developed by our laboratory. These studies showed that human asialoglycoprotein receptor (ASGP-R) and the terminal lactosamine of lacto-N-neotetraose-expressing gonococcal lipooligosaccharide (LOS) play an important role in invasion of PHUECs. Microscopy studies showed that ASGP-R traffics to the cell surface after gonococcal challenge. Co-localization of ASGP-R with gonococci was observed. As ASGP-R-mediated endocytosis is clathrin dependent, clathrin localization in PHUECs was examined after infection. Infected PHUECs showed increased clathrin recruitment and co-localization of clathrin and gonococci. Preincubating PHUECs in 0.3 M sucrose or monodansylcadaverine (MDC), which both inhibit clathrin-coated pit formation, resulted in decreased invasion. N. gonorrhoeae strain 1291 produces a single LOS glycoform that terminates with Gal(beta1-4)Glc-Nac(beta1-3)Gal(beta1-4)Glc (lacto-N-neotetraose). Invasion assays showed that strain 1291 invades significantly more than four isogenic mutants expressing truncated LOS. Sialylation of strain 1291 LOS inhibited invasion significantly. Preincubation of PHUECs in asialofetuin (ASF), an ASGP-R ligand, significantly reduced invasion. A dose-response reduction in invasion was observed in PHUECs preincubated with increasing concentrations of NaOH-deacylated 1291 LOS. These studies indicated that an interaction between lacto-N-neotetraose-terminal LOS and ASGP-R allows gonococcal entry into PHUECs.

Objetivo: Verificar se a eletrolipólise pode ser um método coadjuvante na Reabilitação Cardíaca (RC) de modo a diminuir a gordura abdominal em indivíduos com Doença Cardiovascular (DCV). Métodos: Seis indivíduos, de ambos os sexos, da classe de RC do Centro Clinico de Gaia (CCG), foram distribuídos aleatoriamente em dois grupos, grupo controlo (GC) (n=3) e grupo experimental (GE) (n=3). O GE realizou 8 sessões (duas vezes por semana) de eletrolipólise por microcorrentes 30 minutos antes da classe de RC. Utilizaram-se como meios de avaliação a perimetria, adipometria, bioimpedância e ultrassonografia, análise sanguíneas, bem como a aplicação da Hospital Anxiety and Depression Scale (HADS), Questionário Internacional de Actividade Física (IPAQ) e Questionário Semi-Quantitativo de Frequência Alimentar (QSQFA). Resultados: Através do cálculo da mudança mínima detetável (MMD) verificou-se diminuição do perímetro ao nível do umbigo (3,7cm e 1,5cm) e barriga (4,2cm e 2,83cm) em dois indivíduos do GE e diminuição nas avaliações da ultrassonografia (de 1,3mm a 8,4mm) no GE. Conclusão: Do presente estudo foi possível concluir que nesta amostra existiu uma tendência para a diminuição da gordura abdominal localizada através dos dados obtidos pela perimetria e ultrassonografia.
