Path Integral Quantization of the Symplectic Leaves of the SU(2)* Poisson-Lie Group [PDF]

open access: yes, 1997
The Feynman path integral is used to quantize the symplectic leaves of the Poisson-Lie group SU(2)*. In this way we obtain the unitary representations of U_q(su(2)).

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

open access: yesFEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Influence of genotype and soil on specialized metabolites production and bacterial microbiota associated to wild hop (Humulus lupulus L.): an early-stage study

open access: yesFrontiers in Plant Science
Hop (Humulus lupulus L.) is a dioecious climbing plant that is emblematic for the brewing industry because of its specialized metabolites. Many studies have focused on hop metabolism without considering the microbiota associated with hop tissues ...

Phytochemical characterization of essential oil from Ocimum selloi

open access: yesAnais da Academia Brasileira de Ciências, 2002
Ocimum selloi Benth, a native plant of Brazil, has medicinal uses as anti-diarrheic, antispasmodic and anti-inflammatory product. The yield of essential oils of the inflorescences, containing flowers and seeds, was 0.6%, and the yield of leaves ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

In vitro culture and plant regeneration from the leaves of Primulina danxiaensis

open access: yesGuangxi Zhiwu
Primulina danxiaensis, an endemic species of the Danxia landform within the Gesneriaceae family, exhibits a narrow distribution range and a limited population size, thereby necessitating propagation and conservation via plant tissue culture techniques ...

Morfogênese e produção de biomassa do capim-tanzânia adubado com nitrogênio e cálcio Nitrogen and calcium fertilization on tanzaniagrass morphogenesis and yield

open access: yesRevista Brasileira de Zootecnia, 2007
Neste estudo avaliou-se a influência da adubação com doses combinadas de nitrogênio e cálcio na emissão de folhas e perfilhos, a área foliar e a produção de massa seca da parte aérea do capim-tanzânia. O capim-tanzânia foi cultivado em solução nutritiva,

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Identifying and Characterizing the Circular RNAs during the Lifespan of Arabidopsis Leaves

open access: yesFrontiers in Plant Science, 2017
Leaf growth and senescence are controlled by tight genetic factors involved regulation at multiple levels. Circular RNAs (circRNAs) have recently been reported as the microRNA sponge to accomplish corresponding regulatory roles.

Spanning trees with many leaves: new extremal results and an improved FPT algorithm [PDF]

open access: yes, 2006
We present two lower bounds for the maximum number of leaves in a spanning tree of a graph. For connected graphs without triangles, with minimum degree at least three, we show that a spanning tree with at least (n+4)/3 leaves exists, where n is the ...
