Red Cell Distribution Width and Additive Risk Prediction for Major Bleeding in Non-ST-segment Elevation Acute Coronary Syndrome.
Rev Esp Cardiol
PUBLISHED: 05-20-2014
Show Abstract
Hide Abstract
Red cell distribution width has been linked to an increased risk for in-hospital bleeding in patients with non-ST-segment elevation acute coronary syndrome. However, its usefulness for predicting bleeding complications beyond the hospitalization period remains unknown. Our aim was to evaluate the complementary value of red cell distribution width and the CRUSADE scale to predict long-term bleeding risk in these patients.

Surgical management of middle ear cholesteatoma and reconstruction at the same time.
Colomb. Med.
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
In the surgical management of cholesteatoma, one can opt for a closed technique (simple mastoidectomy) or open surgery (radical mastoidectomy). Open mastoidectomy with reconstruction of the posterior wall and the middle ear in a single surgery combines the advantages of both techniques, namely, adequate surgical exposure, eradication of cholesteatoma, and anatomical reconstruction of the middle ear structures.

Diversity of global rice markets and the science required for consumer-targeted rice breeding.
PLoS ONE
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
With the ever-increasing global demand for high quality rice in both local production regions and with Western consumers, we have a strong desire to understand better the importance of the different traits that make up the quality of the rice grain and obtain a full picture of rice quality demographics. Rice is by no means a 'one size fits all' crop. Regional preferences are not only striking, they drive the market and hence are of major economic importance in any rice breeding / improvement strategy. In this analysis, we have engaged local experts across the world to perform a full assessment of all the major rice quality trait characteristics and importantly, to determine how these are combined in the most preferred varieties for each of their regions. Physical as well as biochemical characteristics have been monitored and this has resulted in the identification of no less than 18 quality trait combinations. This complexity immediately reveals the extent of the specificity of consumer preference. Nevertheless, further assessment of these combinations at the variety level reveals that several groups still comprise varieties which consumers can readily identify as being different. This emphasises the shortcomings in the current tools we have available to assess rice quality and raises the issue of how we might correct for this in the future. Only with additional tools and research will we be able to define directed strategies for rice breeding which are able to combine important agronomic features with the demands of local consumers for specific quality attributes and hence, design new, improved crop varieties which will be awarded success in the global market.

Response to photoxidative stress induced by cold in japonica rice is genotype dependent.
Plant Sci.
PUBLISHED: 01-27-2011
Show Abstract
Hide Abstract
Two japonica rice genotypes, INIA Tacuarí and L2825CA, were analyzed for tolerance to low temperature during early vegetative growth. Effect on photosynthesis, energy dissipation, pigment content, xanthophyll-cycle pool conversion, hydrogen peroxide accumulation, oxidative damage and antioxidant enzyme activities were determined to better understand potential mechanisms for cold tolerance. Photoinhibition was measured using chlorophyll fluorescence and oxidative damage by lipid peroxidation and electrolyte leakage. Both genotypes were demonstrated to be cold tolerant which was consistent with their reduced levels of photoinhibition and oxidative damage compared with a cold-sensitive genotype during chilling stress. The strategy for cold tolerance differed between the two genotypes, and involved different mechanisms for disposal of excess energy. The presence of high lutein concentrations and the existence of active non-harmful energy dissipation processes through the xanthophyll cycle appeared to be responsible for chilling tolerance in INIA Tacuarí. On the other hand, increased cold tolerance of L2825CA relative to INIA Tacuarí was related to the higher constitutive superoxide dismutase (SOD, EC 1.15.1.1), ascorbate peroxidase (APX, EC 1.11.1.11) and catalase (CAT, EC 1.11.1.6).

Large fetal goiter due to placental passage of maternal antithyroperoxidase antibodies.
Fetal. Diagn. Ther.
PUBLISHED: 05-17-2010
Show Abstract
Hide Abstract
We report a case of fetal goiter in a pregnant woman with Graves-Basedow disease. It was diagnosed in the third trimester by a routine ultrasound, and the cordocentesis verified increased levels of thyroxine (T4) and increased autoantibodies (antithyroperoxidase antibodies) that were also increased in maternal blood. Fetal goiter got smaller on the follow-up scans, and the newborn presented hypothyroidism. Current notions on the diagnosis and management of fetal goiter are briefly discussed.

Show Abstract
Hide Abstract
Successful establishment of a Plasmodium vivax sporozoite challenge model in humans is described. Eighteen healthy adult, malaria-naïve volunteers were randomly allocated to Groups A-C and exposed to 3 +/- 1, 6 +/- 1, and 9 +/- 1 bites of Anopheles albimanus mosquitoes infected with P. vivax, respectively. Seventeen volunteers developed signs and symptoms consistent with malaria, and geometric mean prepatent periods of 11.1 days (9.3-11) for Group A; 10.8 days (9.8-11.9) for Group B; and 10.6 days (8.7-12.4) for Group C, with no statistically significant difference among groups (Kruskal-Wallis, P = 0.70). One volunteer exposed to eight mosquito bites did not develop a parasitemia. No differences in parasite density were observed and all individuals successfully recovered after anti-malarial treatment. None of the volunteers developed parasite relapses within an 18-month follow-up. In conclusion, malaria-naive volunteers can be safely and reproducibly infected with bites of 2-10 An. albimanus mosquitoes carrying P. vivax sporozoites. This challenge method is suitable for vaccine and anti-malarial drug testing.

Rhino-orbito-cerebral mucormycosis, a retrospective study of 7 cases.
Acta Otorrinolaringol Esp
PUBLISHED: 06-08-2009
Show Abstract
Hide Abstract
Mucormycosis is an opportunistic fungal infection caused by fungi of the Mucorales order. It has a low incidence and is a potentially lethal infection which generally affects patients who are immunocompromised due to systemic disease. We report 7 cases of rhinocerebral mucormycosis in a retrospective study of 8 years (2000-2008) in haematological patients. An early diagnosis is essential, and therefore there must be a high level of clinical suspicion in patients with predisposing factors. Certainty diagnosis requires fungal cultures or biopsies of the affected areas which prove an invasion of the tissues by the characteristic hyphae. The key to treatment is early and aggressive surgical treatment, together with high intravenous doses of amphotericin B. Despite this, prognosis is poor and mortality is about 70-80%.

[Head and neck paragangliomas. Embryological origin and anatomical characteristics: topographic distribution and vascularization pattern].
Acta Otorrinolaringol Esp
PUBLISHED: 02-28-2009
Show Abstract
Hide Abstract
Paragangliomas are tumors that arise in the extraadrenal paraganglia and result from migration of neural crest cells during embryonic development. Based on their anatomical distribution, innervation and microscopic structure, these tumors can be classified into interrelated families: branchiomeric paraganglia (related to the branchial clefts and arches), intravagal, aortic-sympathetic and visceral-autonomic. Head and neck paragangliomas belong mainly to the first two of these families. The present article is divided into two parts. The first part reviews the embryological origin of these tumors. Special emphasis is placed on the process of neurulation or neural tube formation, neurosegmentation (with a summary of the mechanisms involved in the initial segmentation of the neural tube and of the hindbrain and spinal medulla), and the development of the sensory placodes and secondary inductions in the cranial region. Subsequently, the neural crest is analyzed, with special attention paid to the cranial neural crest. The embryonogenesis of paragangliomas is also described. The second part describes the topographical distribution of head and neck paragangliomas according to their localization: jugulotympanic, orbit, intercarotid, subclavian and laryngeal. The embryonogenesis and most important anatomical characteristics are described for each type.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
