Drawback: Case-control studies are feasible only when it is easy to find controls, i.e. persons whose status vis-à-vis all known potential confounding factors is the same as that of the case's patient: Suppose a case-control study attempts to find the cause of a given disease in a person who is 1) 45 years old, 2) African-American, 3) from ...
Male and female: An experiment is designed to test a new drug on patients. There are two levels of the treatment, drug, and placebo, administered to male and female patients in a double blind trial. The sex of the patient is a blocking factor accounting for treatment variability between males and females. This reduces sources of variability and ...
[12] [3] In the research sphere, off-target effects can confound variables in biological studies leading to potentially misleading and non-reproducible results. [2] In the clinical sphere, the major concerns surround the disruption of vital coding regions leading to genotoxic effects such as cancer. [ 13 ]
In the statistical analysis of observational data, propensity score matching (PSM) is a statistical matching technique that attempts to estimate the effect of a treatment, policy, or other intervention by accounting for the covariates that predict receiving the treatment.
Genomic samples of individual patients could be used to identify predictive factors, or to better understand the specific prognosis of a neurogenomic disease, and use this information to guide treatment options. [78] While there is a clear clinical utility to this approach, the adaptation of this approach is still nonexistent.
Dural metastases can invade the underlying brain and cause focal edema and associated neurologic symptoms. These processes tend to cause seizures early in the course because of their cortical location. Metastasis to the leptomeninges is an uncommon but well-recognized clinical presentation in cancer patients.

Transcription factor Jun is a protein that in humans is encoded by the JUN gene. c-Jun, in combination with protein c-Fos, forms the AP-1 early response transcription factor. It was first identified as the Fos-binding protein p39 and only later rediscovered as the product of the JUN gene. c-jun was the first oncogenic transcription factor ...
