Apoptosis and necrosis


Cell death
• Cells die by one of two mechanisms – necrosis or
apoptosis
• Two physiologically different processes
– Necrosis – death by injury
– Apoptosis – death by suicide
• Apoptosis and necrosis have different characteristics

Necrosis

• Death by accident
• Associated with nonphysiological circumstances that
disrupt cellular homeostasis (eg., ischemia, hypoxia and
poisoning)
• Necrosis is caused by membrane dissolution (osmotic lysis,
s ....etc

Abstract
Introduction.
Proximal tibial bony deficienciesare frequent conditions in primary and revision total kneearthroplasty. Modular tibial metal augmentations wereintroduced to address these deficiencies hoping that they arebetter than other methods of reconstruction (cementreinforced with screws or structural bone graft).
Material and Methods.
During Jan 2000-Jul2009, 407 total knee arthroplasty were performed in ourdepartment. 24 patients had a varus alignament of the kneemore than 25°. For replace ....etc

GENERAL INFORMATION
Ammonia is a compound of nitrogen and hydrogen with the formula NH3. It is a colorless gas with a characteristic pungent odor. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceuticals. Although in wide use, ammonia is both caustic and hazardous. In 2006, worldwide production was estimated at 146.5 million ....etc

Abstract
Granuloma is a medical term for a ball-like collection of immune cells that attempts to remove foreign substances from a host organism. This response is a special type of inflammatory reaction common to a wide variety of diseases. Granulomas are an organised collection of macrophages, whose formation involves the stimulation of macrophages as well as T-Cells. Fault tolerance in swarm robotic systems is essential to the continued operation of swarm robotic systems. Under certain conditions, a failing robot can have a detrimenta ....etc

ABSTRACT
SPECT, the acronym for Single Photon Emission Computed
Tomography, is a nuclear medicine imaging modality, giving information
about a patientâ„¢s specific organ or body system. The patient is
injected with a radiopharmaceutical, which will emit Gamma rays. The
radio activity is collected by an instrument called gamma camera and
the image is reconstructed. SPECT is used to make three dimensional
images of the heart, to perform brain studies and for skeletal ....etc

Determination of Intracranial Tumor Volumes in a Rodent Brain Using Magnetic Resonance Imaging
Abstract
The measurement of tumor volumes is a practical andobjective method of assessing the efficacy of a therapeutic agent.However, the relative accuracy of different methods of assessingtumor volume has been unclear. Using 1-weighted, gadoliniumenhancedmagnetic resonance Imaging ( 1-MRI), Evans Blue infusionand histology we measured intracranial tumor volumes ina rodent brain tumor model (RT2) at days 10, 16 and 18 after implantat ....etc
