Yes: If you ovulate it is possible to conceive.You might want to rethink the app though since ovulation usually occurs14 days before the onset of your period.A short luteal phase, the days from ovulation to the start of your period,is associated with very early pregnancy loss.Count for yourself from the start of one period to the start of the next and that is your cycle length.Then use an ovulation kit ...Read more
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels. This is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors. The first vessels in the embryo form through vasculogenesis, after which angiogenesis is responsible for most, if not all, blood ...Read more
Started spotting brown on cd28 cd31 cd33 of a 36 cycle. Dont have any issues and have had all testing done but am very irregular. What does this mean?
Irregular periods are one of the most common problems Obgyns treat.: If this is one time problem it usually resolves on its own. If this is a recurring problem you should be evaluated. Infections & hormonal changes can cause spotting. If there is a concern for pregnancy then do a home pregnancy test . there are many options available to help regulate the menstrual cycle. Schedule a visit. ...Read more
So i'm on cd31 still no period lack of period symptoms. Only thing I have is low back pain and sore breast. Any ideas if i'm pregnant?
InternalBodyControls: If food made us what we are, they we would likely look like what we eat; reality far more complex. The bodies we inhabit: chemical wizards taking apart molecules & reassembling them like fantastic complex tinker toys under internal controls, called biochemistry. Current knowledge: ischemia, ?pressure diff. & flow may trigger complex responses ?angiogenesis & ?inhibitory controls: balance critical. ...Read more
No, But Necessary: Angio= blood, genesis=origin, creation, beginning, carcino=cancer. Thus both terms refer to origin/beginning, but about very different issues, formation of blood/blood vessels vs. Cancers. The one indirect connection, as mentioned by the other physician, is that no cells, including cancer cells, can survive without nearly by blood flow, thus rapid growing cancers must stimulate blood vessels. ...Read moreSee 1 more doctor answer
Prevention of...: Angiogenesis is the growth of new blood vessels. An antiangeogenesis drugs will reduce the ability to form new blood vessels. They have been used to "starve tumors" to slow the growth. ...Read more
See below: Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels. This is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors. The first vessels in the embryo form through vasculogenesis, after which angiogenesis is responsible for most, if not all, blood vessel growth during development. ...Read more
It helps tumors grow: Angiogenesis is the process whereby blood vessels develop. This occurs in normal tissue, but also in tumors. Certain drugs, like Avastin (bevacizumab) which is used in combination with chemotherapy for colorectal cancer, target angiogenesis in tumors. ...Read moreSee 2 more doctor answers
When a drug inhibits angiogenesis in cancer, does it also inhibit angiogenesis throughout the body?
Not really: When Folkman discovered angiostatin as a way of controlling animal tumors it was tried as a way of controlling cancer in patients. It failed. While blood vessels at the surface of the tumor are necessary for metastasis, most if not all tumors function by anaerobic metabolism and don't need blood. To help destroy tumor treat them in a hyperbaric chamber. ...Read more
Fundamental!: All living things need a blood supply to deliver food, water, and get rid of waste. A circulating cancer cell needs to evade detection, get out of the blood vessel, and establish that blood supply: angiogenesis!. All these actors under molecular control, and likely normal during in utero development. Cut off the blood supply, choke the tumor. ...Read more
Supply line: Living tissues need blood supply to deliver nutrients and oxygen and to get rid of cellular waste. This is especially true in fast growing malignant cells. It's a bit more complex than that but i don't have much space. Blocking angiogenesis is one of the current therapies used for many cancers. ...Read more
Why is it that cancer cells stimulate angiogenesis even if they are known to constitutively perform glycolysis?
Wow...molecular: Listen, i'm just a practicing oncologist but i'll give it a crack. If i remember well, glycolysis is a fairly ineffective way to produce atp compared to cellular respiration so my guess would be that malignant cell will still try to go the route that provides the best production of energy. This requires oxygen and by necessity requires blood flow, achieved by neovascularization thru angiogenesis. ...Read more
For certain cancers: Anti-angiogenic therapies are used in certain malignancies. Whether or not these agents are used in the treatment of a given cancer is based on preclinical and clinical data. Some solid tumors seem to respond, while others devise a way to to become quickly resistant. There are many drugs of this class that target different pathways, and many clinical trials are currently being performed. ...Read moreSee 2 more doctor answers
