Biodegradable Metal-Organic Framework-Based Microrobots (MOFBOTs).

2020

Microrobots and metal–organic frameworks (MOFs) have been identified as promising carriers for drug delivery applications. While clinical applications of microrobots are limited by their low drug loading efficiencies and the poor degradability of the materials used for their fabrication, MOFs lack motility and targeted drug delivery capabilities. The combination of these two fields marks the beginning of a new era; MOF‐based small‐scale robots (MOFBOTs) for biomedical applications. Yet, biodegradability is a major hurdle in the field of micro‐ and nanoswimmers including small‐scale robots. Here, a highly integrated MOFBOT that is able to realize magnetic locomotion, drug delivery, and selec…

Inferring phytoplankton community composition with a fatty acid mixing model

2015

Abstract. The taxon specificity of fatty acid composition in algal classes suggests that fatty acids could be used as chemotaxonomic markers for phytoplankton composition. The applicability of phospholipid-derived fatty acids as chemotaxonomic markers for phytoplankton composition was evaluated by using a Bayesian fatty acid-based mixing model. Fatty acid profiles from monocultures of chlorophytes, cyanobacteria, diatoms, euglenoids, dinoflagellates, raphidophyte, cryptophytes and chrysophytes were used as a reference library to infer phytoplankton community composition in five moderately humic, large boreal lakes in three different seasons (spring, summer and fall). The phytoplankton commu…

Obesity and survival in operable breast cancer patients treated with adjuvant anthracyclines and taxanes according to pathological subtypes: a pooled…

2013

Obesity is an unfavorable prognostic factor in breast cancer (BC) patients regardless of menopausal status and treatment received. However, the association between obesity and survival outcome by pathological subtype requires further clarification. METHODS: We performed a retrospective analysis including 5,683 operable BC patients enrolled in four randomized clinical trials (GEICAM/9906, GEICAM/9805, GEICAM/2003-02, and BCIRG 001) evaluating anthracyclines and taxanes as adjuvant treatments. Our primary aim was to assess the prognostic effect of body mass index (BMI) on disease recurrence, breast cancer mortality (BCM), and overall mortality (OM). A secondary aim was to detect differences o…

Rubefacientu (mentola un niacīna) izraisīto mikrocirkulācijas reakciju novērtējums ādas dažādos dziļumos

2017

Ādai ir lokāla neiro-imuno-endokrīnā sistēma, kas lielā mērā atspoguļo organisma norises, kalpojot par sava veida „veselības indikatoru”. Īpaši pievilcīga un relatīvi pieejama ir ādas mikrocirkulācijas funkciju novērtēšana, ko var neinvazīvi veikt ar optiskām metodēm. Parasti praksē šādu reakciju novērtēšanai tiek lietoti standartizēti provokācijas testi, kā, piemēram, lokālas sildīšanas tests, vai acetilholīna jontoforēze. Taču bieži vien ādas sarežģītā mikrocirkulācija un liela regulācijas mehānismu daudzveidība apgrūtina rezultātu viennozīmīgu interpretāciju. Šajā kontekstā daudzsološa šķiet bispektrālā attēlveides fotopletizmogrāfija - optiska metode ar kuras palīdzību, izmantojot atšķi…

Characterization and antimicrobial activity of the volatile components of the flowers of Magydaris tomentosa (Desf.) DC. collected in Sicily and Alge…

2014

The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
