Hipoxia tumoral. Papel del factor inducible por hipoxia [PDF]

Actas Urológicas Españolas, 2009
Los tumores sólidos, por lo general, existen y progresan en un ambiente de hipoxia; así se observa que las células tumorales son resistentes a la apoptosis y se acompañan de un aumento de la angiogénesis, volviéndose más agresivas, con capacidad invasora y resistentes al tratamiento.

[Considerations on hypoxia and altitude]. [PDF]

Rev Med Inst Mex Seguro Soc
Resumen La hipoxia asociada a la altitud se conoce como hipoxia hipobárica y está relacionada con la disminución de la presión barométrica y la presión inspirada de oxígeno; conforme estos disminuyen, la hipoxia incrementa. Los habitantes de lugares con gran altitud se aclimatan-adaptan con cambios morfológicos, fisiológicos y genéticos por ...

Interleukins expression by rat Lymphocytes exposed to chronic intermittent normobaric hypoxia [PDF]

Frontiers in Physiology
Acute and chronic hypoxia modulate the expression of inflammatory mediators known as cytokines. However, studies in chronic and intermittent hypobaric or normobaric hypoxia, like those described in miner’s population, are scarce or absent. In this study,

Estudio de marcadores de estrés celular y parámetros metabólicos en un microambiente hipóxico in vitro en queratinocitos inmortalizados con los oncogenes virales del VPH-18

Odontoestomatología, 2022
Introducción: La hipoxia es una condición de deficiencia de oxígeno en las células de los tejidos que puede ocurrir en situaciones fisiopatológicas, como el cáncer (1,2).

Estudio comparativo de 2 modelos de inducción de hipoxia en células de carcinoma oral de células escamosas, evaluando cambios morfológicos, proteicos y metabólicos

Odontoestomatología, 2022
Objetivos: Evaluar los cambios morfológicos, proteicos y metabólicos presentados en líneas de COCE sometida a dos modelos de hipoxia celular. Métodos: Utilizaremos el método de hipoxia química inducida por cloruro de cobalto (CoCl2) y el modelo variante

Cardiovascular Risk Is Increased in Miner’s Chronic Intermittent Hypobaric Hypoxia Exposure From 0 to 2,500 m?

Frontiers in Physiology, 2021
Over the past 40 years, mining activities in Chile have relocated miners who normally live at sea level to work at high altitudes. This results in a form of chronic intermittent hypobaric hypoxia (CIHH) characterized by alternating periods of work at ...

The role of cell size in shaping responses to oxygen and temperature in fruit flies

Functional Ecology, Volume 37, Issue 5, Page 1269-1279, May 2023., 2023
Read the free Plain Language Summary for this article on the Journal blog. Abstract The body size of an animal is strongly coupled to key ecological traits such as fecundity, mortality and growth. Ectothermic animals mature at smaller body sizes in warmer conditions and under low oxygen availability (hypoxia).

Nocturnal dissolved organic matter release by turf algae and its role in the microbialization of reefs

Functional Ecology, Volume 36, Issue 8, Page 2104-2118, August 2022., 2022
Read the free Plain Language Summary for this article on the Journal blog. Abstract The increased release of dissolved organic matter (DOM) by algae has been associated with the fast but inefficient growth of opportunistic microbial pathogens and the ongoing degradation of coral reefs.

Current development and future perspective of IDH1 inhibitors in cholangiocarcinoma

Liver Cancer International, Volume 3, Issue 1, Page 17-31, February 2022., 2022
Abstract Background and Aims Biliary tract cancer (BTC) represents a major public health problem due to its increasing rates of incidence and mortality, especially the intrahepatic cholangiocarcinoma (IHCCA) subtype. First line palliative systemic treatment with cisplatin and gemcitabine has been the unique level IA evidence option until last few years

Neuropeptides in the developing human hippocampus under hypoxic–ischemic conditions

Journal of Anatomy, Volume 239, Issue 4, Page 856-868, October 2021., 2021
Hypoxia‐ischemia during the perinatal period could damage the hippocampal interneuron populations which might lead to the appearance of different problems during subsequent development. Interneurons containing Somatostatin and Neuropeptide Y located in the hippocampal ammonic fields are affected differently, although there is a global reduction after ...
