Respiration of a Marine Teleost, the Porgy, under Normoxic, Resting Condition.

The Respiration of Cancer Pagurus under Normoxic and Hypoxic Conditions

The respiration of Cancer pagurus under normoxic conditions and its respiratory responses to hypoxia are described. Respiration of quiescent crabs is characterized by a rhythmic pattern of ventilation and cardiac activity in which periods of apnoea and bradycardia of approximately 5 min duration alternate with longer periods of active ventilation and cardiac activity. The significance of this r...

Respiration Properties of Tree-Ripe Mango under CA Condition

Respiration rate is the necessary parameter for designing the storage conditions. In the present investigation, the effects of storage temperatures (5, 10, 15, 20, 25oC) and gas composition on the O2 consumption and the CO2 production have been studied by using the flow through system. The ratio of the respiration rate under controlled atmosphere (CA) conditions (1.6 to 20.7% O2, 0.2 to 10.2% C...

Systemic modeling myeloma-osteoclast interactions under normoxic/hypoxic condition using a novel computational approach

Interaction of myeloma cells with osteoclasts (OC) can enhance tumor cell expansion through activation of complex signaling transduction networks. Both cells reside in the bone marrow, a hypoxic niche. How OC-myeloma interaction in a hypoxic environment affects myeloma cell growth and their response to drug treatment is poorly understood. In this study, we i) cultured myeloma cells in the prese...

Cardiovascular changes under normoxic and hypoxic conditions in the air-breathing teleost Synbranchus marmoratus: importance of the venous system.

Synbranchus marmoratus is a facultative air-breathing fish, which uses its buccal cavity as well as its gills for air-breathing. S. marmoratus shows a very pronounced tachycardia when it surfaces to air-breathe. An elevation of heart rate decreases cardiac filling time and therefore may cause a decline in stroke volume (V(S)), but this can be compensated for by an increase in venous tone to mai...

Erythropoietin ' s impact on endurance performance under normoxic condition and upon acclimatization to moderate altitude
