Analysis of the effects of co-exposure to antibiotics and cadmium on sea urchin embryos
2014
In order to understand the mechanisms of responses to changes in the physical and chemical environment, as well as the mechanisms of developmental pathways, we investigated by RT-qPCR assays and light microscopy observations the impact of antibiotics and cadmium in P. lividus sea urchin embryos. In particular we inspected development and biomarkers for free radical damage and apoptosis. During development embryos were exposed to an antibiotic mix (Ab mix, usually added to sea urchin cultures) or to sulfamethoxazole/trimethoprim mix (TMP/SMX, usually added to aquacultures) and/or levels of 10-5, 10-4, 10-3 M CdCl2. Even though treatment with TMP/SMX apparently did not affect development, it …
Introduction of Multiflow for HSDPA
2012
This paper introduces a multi-cell transmission scheme for High-Speed Downlink Packet Access (HSDPA) networks, called Multiflow. In this concept, downlink data is transmitted to a user terminal at the border of two cells from one or both of the cells. The cells may belong to same NodeB or to two different NodeBs. The data flows are separated by different scrambling codes used by each associated cell, thus the flows can be treated independently. This provides increased multi-user diversity by means of flexibility in downlink resource management, in addition to the spatial diversity of multiple transmission locations. Another important gain mechanism for this scheme is realized by short-term …
Two-phase routing in three-dimensional blocked optical tori
2014
The contribution of this paper is an all-optical 3D network architecture. We describe scheduled, two-phase routing for it. The three-dimensional blocked optical torus BOT of block size b consists of b2 × b2 × b2 nodes for the first phase routing. Processors are evenly deployed at the underlying torus so that every bth node consists of a processor. Additionally, a BOT consists of b3 blocks of b × b × b subnetworks for the second phase routing. Routing of each packet is done in two phases. Firstly, packets are routed from source processor to an intermediate target node at the target block. Secondly, packets are routed from the intermediate targets at the target block to the target processor (…
On the Choice of the Extracellular Vesicles for Therapeutic Purposes
2019
Extracellular vesicles (EVs) are lipid membrane vesicles released by all human cells and are widely recognized to be involved in many cellular processes, both in physiological and pathological conditions. They are mediators of cell-cell communication, at both paracrine and systemic levels, and therefore they are active players in cell differentiation, tissue homeostasis, and organ remodeling. Due to their ability to serve as a cargo for proteins, lipids, and nucleic acids, which often reflects the cellular source, they should be considered the future of the natural nanodelivery of bio-compounds. To date, natural nanovesicles, such as exosomes, have been shown to represent a source of diseas…

Tiesas izdevumu regulējuma mijiedarbība ar personas tiesībām uz taisnīgu tiesu.
2022
Ņemot vērā tiesas izdevumu apmēra aktualitātes nemainīgumu, darba mērķis ir izvērtēt, vai šobrīd Latvijā pastāvošais tiesas izdevumu regulējums nesamērīgi neierobežo personu tiesības uz taisnīgu tiesu. Tādējādi darba uzdevums ir sākotnēji izpētīt tiesas izdevumu veidus, identificējot ar tām saistītās problēmas. Īpaši izceļot valsts nodevu regulējumu un aplūkojot tādus aspektus kā nepareizu pieauguma jēdziena interpretāciju un pirmās instances tiesas tiesneša pārlieku lielo rīcības brīvību valsts nodevas apmēra noteikšanā. Darba praktiskajā daļā tiek turpmāk izvērstas problēmas, kas saistāmas ar personu atbrīvošanu no tiesas izdevumu samaksas. Secināms, ka Latvijā valsts nodevu apmērs ir nes…

2016
Diplomdarba mērķis izpētīt ar darba samaksu saistītos teorētiskos aspektus, analizēt uzņēmuma izvēlēto samaksas sistēmu un izstrādāt priekšlikumus tās pilnveidošanai. Diplomdarbā autore pēta darba samaksas teorētiskos jautājumus, kā arī analizē konkrēta uzņēmuma SIA “TRANS” darba samaksas sistēmu. Kā rezultātā autore ir konstatējusi SIA “TRANS” eksistējošas nepilnības un izstrādājusi priekšlikumus to novēršanai.
Vascularized lymph node transfer for treatment of extremity lymphedema: An overview of current controversies regarding donor sites, recipient sites a…
2018
As lymphatic microsurgery has become more common, vascularized lymph node transfer ascended to the forefront in many centers for the surgical management of advanced stages of lymphedema showing substantial clinical improvement. However, no consensus has been reached among experts regarding many details of the procedures, including patient selection criteria, type of treatment, donor, and recipient sites and postoperative evaluation of the outcome. Here, we will review these issues and provide the current results of this procedure.
