Subcutaneous veins detection and backprojection method using Frangi vesselness filter

2015

Blood vessels detection is a common task performed in numerous medical procedures. During regular medical treatments venipuncture procedures are performed for invasive medication and blood sampling. Near infrared imaging technology can be used to visualize the subcutaneous veins in cases of difficult venous access. In this paper the methods for veins centerline detection and back projection is presented. In order to highlight the suitable veins for venipuncture, the centerline of larger veins are detected and back projected to the original image. The method is applied on the near infrared images of subjects selected from four different classes of skin tone. This can be helpful to medical st…

Supplementation with cactus pear (Opuntia ficus-indica) fruit decreases oxidative stress in healthy humans: a comparative study with vitamin C.

2004

Background: Cactus pear (Opuntia ficus-indica) fruit contains vitamin C and characteristic betalain pigments, the radical-scavenging properties and antioxidant activities of which have been shown in vitro. Objective: We investigated the effects of short-term supplementation with cactus pear fruit compared with vitamin C alone on total-body oxidative status in healthy humans. Design: In a randomized, crossover, double-treatment study, 18 healthy volunteers received either 250 g fresh fruit pulp or 75 mg vitamin C twice daily for 2 wk, with a 6-wk washout period between the treatments. Before (baseline) and after each treatment, 8-epiprostaglandin F2α (8-epi-PGF2α) and malondialdehyde in plas…

Hyaluronan alkyl derivatives-based electrospun membranes for potential guided bone regeneration: Fabrication, characterization and in vitro osteoindu…

2020

Item does not contain fulltext The aim of the work was to determine the effects of the chemical functionalization of hyaluronic acid (HA) with pendant aliphatic tails at different lengths and free amino groups in terms of chemical reactivity, degradation rate, drug-eluting features, and surface properties when processed as electrospun membranes (EM) evaluating the osteoinductive potential for a possible application as guided bone regeneration (GBR). To this end, a series of HA derivatives with different aliphatic tails (DD-Cx mol% ≈ 12.0 mol%) and decreasing derivatization of free amino groups (DD(EDA) mol% from 70.0 to 30.0 mol%) were first synthesized, namely Hn. Then dexamethasone-loaded…

Disasters in the Society of Fear

2019

From immemorial times, Aborigines and ancient cultures were frightened of disasters because these events were seen as divine reprisals or punishment for their sins (as the Noah’s Ark myth shows). Although modern science introduced instrumental thinking to understand disasters, improving the quality of life, it is equally true that capitalism obscured the diagnosis of scientists to protect the system. Blind to see the real problems of earth, today, capitalism offers distorted answers to the problem of climate change, migration and refugee crises, and even to the economic downturn. Based on the tactics of blaming Others, the elite allude to poverty as the precondition toward humanitarian disa…

Zvaigžņu likumi un senlatviskā gadskārta

2021

Pieņemot, ka Lielais Sprādziens (jeb Pasaules pirmsākums) noticis pirms 15 miljardiem gadu, salīdzinājumā ar kosmiskiem mērogiem Zemes civilizācijai ļoti īsā laika sprīdī ir izdevies atklāt galvenos dabas pamatlikumus: Ņūtona vispasaules gravitācijas likumu un Keplera likumsakarības, kas apraksta planētu kustību ap zvaigzni. Zemei viena gada laikā apritot ap Sauli – zvaigzni, kuras gūstā (jeb gravitācijas laukā) atrodamies, atšķirami četri svarīgi punkti, kas dabā samanāmi kā pārmaiņas dienas un nakts garumā un saņemtajā siltuma daudzumā. Tie ir Saules atrašanās vieta vienā no četriem ekliptikas – Saules redzamā ceļa starp zvaigznēm – punktiem: vasaras un ziemas saulgrieži (saulstāvji), pav…
