The species is distributed in eastern Mexico, Central America, and northwestern South America (Colombia) (Miller 1986; Strand 1913; Vinciguerra 2010). Even though many specimens can be found in collections worldwide, very little is known about their biology (Vinciguerra 2010, González et al. 2013, González & Domagała 2019). Even though we are currently following Moraes & Duarte (2014) by placing the species in the genus Telchin. Ongoing research (Worthy, Zilli & González, in prep.) is pointing to revalidate the genus Divana. Material examined: HONDURAS: 1 Ƌ, Atlántida, La Ceiba, Río bonito CURLA camp 8km W, 5 km S., 150m, 6.

Moraes & Duarte (2014) synonymize this genus in Telchin, and we are momentarily treating this taxon within the genus, an ongoing research (Worthy, Zilli & González, in prep.) will revalidate the genus Amauta. This species, originally described (as Castnia procera) from material received by “M. de l’Orza” from Guatemala, and it differs from “[C.] cacica ”, by “… ses ailes supérieures un peu plus pointues au sommet, par l’absence de la petite tache blanche discoïdale, par ses ailes intérieures dont la bande transversale est moitié plus étroite, et enfin par le dessous des ailes qui est entièrement d’un brun uniforme ainsi que le corps.” (Boisduval, [1875]). Currently considered a ssp. of A. cacica, it is found from North America (Mexico) throughout Central America down to Panama. Some authors, however, have mentioned the South American ssp. cacica , as present in Central America (Maes 1998-1999; Chacón & Montero 2007; González & Hernández-Baz 2012; Miller et al. 2012). This subspecies had been observed perched and feeding on Heliconia pogonantha Cuf. (Heliconiaceae) inflorescences (Miller & Sourakov 2009). The latter could be also a host plant (Miller & Sourakov 2009; Domagała et al. 2017).

Prometheus zagraea salvina (Westwood); González & Domagała, 2019:17. Even though it is not uncommon, very little is known about this species whose two recognized ssp. can be found from Colombia to Central America (Lamas 1995, Miller 1986). The nominate ssp. has been associated with Aechmea magdalenae (André) André ex Baker (Bromeliaceae) (Miller, 1986), thus it should not be surprising that P. zagraea salvina feeds on another bromeliad within its range. This particular ssp. was previously known from Costa Rica and Panama (Lamas 1995), thus this new report from northern Nicaragua considerably expands its geographic range. The species P. zagraea has been mentioned as a member of a mimicry complex that includes different families of Lepidoptera (Miller 1986, González et al. 2010; González & Hernández-Baz 2012). One of the co-authors (EVDB) was able to obtain detailed information on associated species from Cerro Jesus, Nicaragua. In this locality, several “tiger-patterned” Lepidoptera co-exist and the Mullerian mimetic ring is complex. Several associated lepidopterans fly synchronously: Chetone angulosa (Walker, 1854) (Erebidae), Lycorea halia atergatis Doubleday, 1847, Mechanitis polymnia (L. 1758), Eueides isabella (Stoll, 1781), Heliconius ismenius Latreille, [1817], Consul fabius cecrops (Doubleday, [1849]) (Nymphalidae). Even though both, males and females of P. zagraea salvina present the basic “tiger-pattern” of the others in the mimicry complex, females have broader wings and are larger, and the males seem to mimic different species. Even though the typical flight pattern of Castniidae is fast, both sexes of P. zagraea salvina adopt the slow flight pattern of Heliconius butterflies. Besides this castniid, the other Batesian mimic found in the area was C. fabius cecrops, which is not very common. Also, three specimens of Chetone angulosa were attracted to a light trap the night before the specimens of P. z. salvina were collected, however, this Erebidae was not active during the day but it behaves exactly as does P. z. salvina.

Architect-als-Tuinman: ontwerpen met de aard van de plaats in wording
No full textThis research through reflective practice investigates the relationship between architecture and natures; a nature is an ecosystem that is allowed to emerge.
It has developed ways of designing architectures with these unpredictable processes. By supporting their agency, places develop their resilience: their biological and cultural complexity and diversity. Processes of growth as well as decay are nurtured and expressed.
Designing with emergent natures has been investigated through contextualising and reflecting on three ongoing series of work in my practice that combine buildings and landscapes, looking at them separately and together. Through this process, a fourth series has appeared.
The tools used are open patterns that fall into two categories:
(1)setting - physical - and (2) nurturing - behavioural. They are developed in dialogue with, and within, the ecosystems, especially with the inhabitants. These patterns set situations and tweak the dynamic processes over time. They choreograph the elements of architecture - the void, the climate, the resources and the living - whilst affording them agency.
For a gardener architect, architecture is the improvisatory choreography of the elements' rhythms. The role of the designer is dual: (1) to design patterns that will guide the performance of a place by its multiple inhabitants and (2) simultaneously develop a language of patterns, ecological memes, for use elsewhere. Setting and nurturing patterns grow together in a systemic dialogue.
Serendipitously, the gardener architect nurtures natures by creating gardens where they can thrive.status: Publishe

Nucleoside analogs in chronic lymphoid malignancies : studies of the clinical effects and mechanisms of action of cladribine and fludarabine
No full textLa 2-Chloro-2’-désoxyadénosine (CdA, Cladribine) est un agent de chimiothérapie qui appartient à la famille des analogues des purines. La CdA est particulièrement active dans les néoplasies issues des tissues lymphoïdes, comme la leucémie lymphoïde chronique (LLC) de type B. La CdA est une pro-drogue qui n’est activée qu’après avoir été convertie en CdA triphosphate par des enzymes fortement exprimées dans les cellules lymphoïdes. Le CdA triphosphate, considéré comme le métabolite toxique de la CdA, inhibe la synthèse de l’ADN et de l’ARN, et active les voies de l’apoptose. Comme la réparation de l’ADN peut impliquer une néosynthèse d’ADN, il est concevable que celle-ci puisse également être inhibée par la CdA. Par conséquent, la CdA pourrait être capable d’accroître la toxicité des agents qui induisent des lésions de l’ADN susceptibles de réparation. Dans ce travail, nous avons d’abord démontré qu’il existait in vitro dans les lymphocytes LLC une forte cytotoxicité synergique entre la CdA et les agents alkylants ou les rayons UV, deux traitements qui induisent des lésions potentiellement réparables de l’ADN. Nous avons poursuivi nos efforts afin d’expliquer cette interaction. Nous avons observé que la CdA était capable d’inhiber la synthèse réparatrice de l’ADN, qu’elle survienne spontanément ou qu’elle soit provoquée par les agents alkylants ou les rayons UV. Nous avons émis l’hypothèse selon laquelle ce mécanisme est à la base de la synergie, et que l’impossibilité pour la cellule d’achever la réparation complète de l’ADN constitue un signal de mort cellulaire par apoptose. Les résultats obtenus in vitro nous ont encouragés à mettre sur pied une étude clinique de l’association de CdA avec le cyclophosphamide, un agent alkylant, pour des patients atteints de LLC ou de lymphomes indolents. Cette étude, construite comme une étude de Phase I, nous a permis de définir le dosage optimal des deux agents de chimiothérapie. Nous avons observé un taux de réponse encourageant, compte tenu du fait que la population étudiée était de mauvais pronostic. Certaines réponses se sont avérées durables, suggérant que la synergie observée in vitro s’était produite en clinique. En conclusion, nos études illustrent le bénéfice potentiel de l’association d’analogues des purines comme le CdA avec des agents de chimiothérapie qui ciblent l’ADN, comme le cyclophosphamide2-Chloro-2-deoxyadenosine (CdA, cladribine) is a chemotherapeutic agent belonging to the family of purine analogs. CdA is particularly active in malignancies arising from lymphoid tissues, such as B-cell chronic lymphocytic leukemia (CLL). CdA is a prodrug that must be converted into CdA triphosphate by the action of enzymes highly expressed in lymphoid cells, as an absolute requirement for cytotoxicity. CdA triphosphate inhibits various processes involved in DNA and RNA synthesis, and activates apoptotic pathways. Because enzymes involved in DNA synthesis are also involved in DNA repair, it is conceivable that CdA might interfere with forms of repair that require DNA synthesis. If this mechanistic interaction occurs, CdA should be able to enhance cell killing by agents that induce DNA lesions susceptible to removal by repair mechanisms. In the present work, we firstly demonstrated in CLL lymphocytes a strong synergistic interaction, in term of cell killing by apoptosis, between CdA and DNA alkylating agents or UV-C radiation, both conditions causing DNA damage susceptible to removal by repair processes. We then sought to explain the basis for this favorable interaction. We observed that CdA was able to inhibit DNA repair synthesis occurring in CLL cells, either spontaneously or after external DNA damage by UV-C light or mafosfamide. We hypothesized that the latter mechanism might be at the basis of synergism and that inability of leukemic cells to complete repair might signal toward apoptosis. Finally, the results obtained in vitro led us to study the combination of CdA with cyclophosphamide, an alkylating agent, in patients suffering CLL or indolent lymphomas. The study was conceived as a Phase I study, enabling us to determine the optimal dosage of both drugs. We observed an interesting response rate in very advanced patients with poor prognostic factors. Some of the responses were long-lasting, suggesting that in vitro synergism may have translated clinically. In conclusion, our studies illustrate the potential benefit of combining purine analogs, such as CdA, with other treatment modalities, here DNA-damaging conditions, in the hope of reinforcing their antitumoral activity.Thèse de doctorat en sciences biomédicales (SBIM 3)--UCL, 200
