The phrase "are often concomitant" is correct and usable in written English.
It can be used to describe two or more things that frequently occur together or are associated with each other.
Example: "In many cases, stress and poor health are often concomitant, leading to a decline in overall well-being."
Alternatives: "are often associated" or "frequently occur together".
Both conditions are often concomitant and seem to be more pronounced with increasing postmenopausal years.
Genetic and expression profiling studies of HCC have demonstrated the alterations of a variety of mutations and expression of oncogenes and/or tumor-suppressor genes in the carcinogenesis of liver cancer, which are often concomitant with the deregulation of an important signaling pathway, such as p53, AP-1, and the mitogen-activated protein kinases (MAPKs) pathway [ 16, 17].
In the literature, it is reported that bacteria development is often concomitant with benthic microalgae [36] and they adapt quickly to the different organic microalgal exudates with substrate-specific responses regarding enzyme activity, usually resulting in compositional shifts and stimulated bacterial growth and metabolic activity [12], [21].
Most studies are adjusted for sex and age while some considered smoking, which is often concomitant with alcohol.
Chronic exposure to hyperglycemia or its related ischemia/hypoxia with oxidative stress leads to an increased risk for peripheral neuropathy (6), which is characterized by neurodegeneration that is often concomitant with neuroregeneration (7).
The choice of 48 hpi as the key time for our gene expression study is further motivated by the fact that in various plant-pathogen interactions the accumulation of defense-related transcripts in the host is often concomitant to the formation of appressoria and the development of the intracellular hyphae [ 49– 52].
The cell response to stress is complex and is often concomitant with damage to a number of biomolecules including proteins [ 35- 37]; therefore, it is conceivable that some repair mechanisms such as ubiquitin proteasome pathway (UPP) are involved in the cell response to oxidative stress.
Moreover, our findings provided evidence for a potential mechanism to explain the antiproliferative effects of type I IFN in certain cell types, considering that autophagy is often concomitant with cell cycle arrest and senescence., It is well established that type I IFN mediates signaling primarily through the JAK-STAT pathway.
The labeling of other neuronal types is relatively rare, and single neuron reconstructions are often obstructed by concomitant labeling of more abundant neurons.
Greater age differences are often accompanied by concomitant differences in maturity, life experiences, social position and financial resources, which can render relationships inherently unequal and pose a source of risk for women's health [ 23- 26].
Many constituents of food and some medications interact with ferrous salts, such that iron uptake is best when taken on an empty stomach, but gastrointestinal side effects are often improved by concomitant food, so there can be a difficult balance between maximizing uptake and minimizing gastrointestinal side effects.
