Mediterranean Diplodus annularis (Teleostei: Sparidae) and its brain parasite: Unforeseen outcome
2005
Patterns of parasite load and aggregation of the bird trematode Cardiocephaloides longicollis in its main intermediate host in the Mediterranean, the annular sea bream, Diplodus annularis, were studied in a large sample collected off Valencia (Spain) and are discussed within the context of the parasite induced host mortality hypothesis. The metacercariae were located within large composite cysts of host origin in the ventricles of the optic lobes of the cerebrum. A weak immunological response was detected in older fish, which was significantly associated with the total parasite load. Although the mean abundance of C. longicollis showed a tendency to increase with host size, the infection le…
El darwinismo social y la filología decimonónica: rastreo de la ideología a través de la prensa histórica
2021
espanolEn este trabajo, se persigue demostrar que el pensamiento darwiniano estaba enraizado en concepciones supremacistas y que este pensamiento no solo marco la biologia decimononica, sino tambien el resto de disciplinas sociales y humanas al convertirse la biologia como maximo exponente de lo que se entendia como ciencia. No solo se tomaron como premisas los presupuestos metodologicos de la biologia, sino tambien su concepcion supremacista. Y la filologia no fue una excepcion. A traves del rastreo en la prensa historica decimononica, queremos demostrar que estas ideas calaron en la sociedad, pero tambien en el pensamiento filologico hispanico del siglo XIX. La reconstruccion de la preten…
Early menopause is associated with lack of response to antiviral therapy in women with chronic hepatitis C.
2011
Background & Aims Chronic hepatitis C (CHC) and liver fibrosis progress more rapidly in men and menopausal women than in women of reproductive age. We investigated the associations among menopause, sustained virologic response (SVR), and liver damage in patients with CHC. Methods We performed a prospective study of 1000 consecutive, treatment-naive patients 18 years of age and older with compensated liver disease from CHC. Liver biopsy samples were analyzed (for fibrosis, inflammation, and steatosis) before patients received standard antiviral therapy. From women (n = 442), we collected data on the presence, type, and timing of menopause; associated hormone and metabolic features; serum lev…
Pacientu apmierinātība pēc Longo operācijas
2020
Bakalaura darba tēma: Pacientu apmierinātība pēc Longo operācijām dienas stacionārā. Tēmas aktualitāte: Hemoroidālā saslimšana ir visiem zināma, tā ir viena no biežāk sastopamajām gastrointestinālajām slimībām, kas skar abus dzimumus visbiežāk vecuma diapazonā no 45-65 gadiem. Terapijas metodes hemoroidālai saslimšanai ir daudz un dažādas, tās balstītas lielākoties uz liģēšanas un ekscīzijas principiem, jaunākās metodes tiek izstrādātas, lai mazinātu audu dissekciju ar mērķi samazināt pēcoperācijas sāpes un asiņošanu. 1993.gadā tika radīta jauna alternatīva metode Ferguson un Milligan-Morgan tehniskajām metodēm, - Longo operācija jeb steiplera hemoroīdektomija. Šajā darbā tiks apskatīta vie…
Low-risk isn’t no-risk: Perinatal treatments and the health of low-income newborns
2019
We investigate the effects of perinatal medical treatments on low-income newborns who are classified as low-risk. A policy rule in The Netherlands states that low-risk deliveries before week 37 should be supervised by physicians and later deliveries only by midwives with no physician present. This creates large discontinuities in the probability of receiving medical interventions only physicians are allowed to perform. Using a regression discontinuity design, we find that babies born slightly before the week-37 cutoff are significantly less likely to die than babies born slightly later. Our data suggest that physician supervision of birth reduces the likelihood of adverse events such as fet…
Telomere Length in Circulating Leukocytes is Associated with Lung Function and Disease
2014
Several clinical studies suggest the involvement of premature ageing processes in chronic obstructive pulmonary disease (COPD). Using an epidemiological approach, we studied whether accelerated ageing indicated by telomere length, a marker of biological age, is associated with COPD and asthma, and whether intrinsic age-related processes contribute to the interindividual variability of lung function. Our meta-analysis of 14 studies included 934 COPD cases with 15 846 controls defined according to the Global Lungs Initiative (GLI) criteria (or 1189 COPD cases according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) criteria), 2834 asthma cases with 28 195 controls, and s…

Mutations and Deregulation of Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR Cascades Which Alter Therapy Response.
2012
The Ras/Raf/MEK/ERK and PI3K/PTEN/Akt/mTOR cascades are often activated by genetic alterations in upstream signaling molecules such as receptor tyrosine kinases (RTK). Certain components of these pathways, RAS, NF1, BRAF, MEK1, DUSP5, PP2A, PIK3CA, PIK3R1, PIK3R4, PIK3R5, IRS4, AKT, NFKB1, MTOR, PTEN, TSC1, and TSC2 may also be activated/inactivated by mutations or epigenetic silencing. Upstream mutations in one signaling pathway or even in downstream components of the same pathway can alter the sensitivity of the cells to certain small molecule inhibitors. These pathways have profound effects on proliferative, apoptotic and differentiation pathways. Dysregulation of components of these cas…
The Pratz le Curtillet settlement
2016
Among the earliest habitats of the early Middle Ages studied in Franche-Comté, the Pratz le Curtillet a settlement sets itself apart by its location in the Jura highlands, renowned for its remoteness and inhospitable landscapes. On the Lizon plateau, the scope of the archaeological work explored on the 16 hectares and the quality of the remains still constitute an exceptional complex today. An imposing 16m by 13m stone building flanked by an annex forms the residential part of the estate, while sheltering fodder and livestock, while the second building houses a forge. Domestic and artisanal equipment provide ample documentation on the living conditions of this small community of high status…

The longitudinal magnetoresistance (MR) of the Ni films on (011) PMN-PT, measured at room temperature in the magnetic field range of −0.3 T < μ0H < 0.3 T, is found to depend on the crystallographic direction and polarization state …
