The phrase "activity which are often" is not correct in written English.
It contains a subject-verb agreement error; "which" should refer to "activities" in the plural form.
Example: "Activities which are often overlooked can lead to significant improvements in productivity."
Alternatives: "activities that are frequently" or "tasks that are commonly".
Ure2p shows glutathione-dependent peroxidase (GPx) activity, which is often an adjunct activity of GSTs, but wild-type Ure2p shows no detectable GST activity toward the standard substrate 1-chloro-2,4-dinitrobenzene (CDNB).
Subjects with risk factors such as hypertension, obesity, insulin resistance, among others, generally show a high sympathetic activity which is often presented before the clinical manifestation of hypertension.
The main characteristic of cancer cells is their increased proliferative activity, which is often caused by aberrations in cell cycle regulation [ 2].
First, tree plantation expansion can come at the expense of agricultural activity, which is often the main source of income for rural Chileans.
However, chronic low-grade systemic inflammation, which is observed in some COPD patients, could also be involved [ 7], as well as biological mechanisms related to decreased physical activity, which is often observed with ageing [ 8].
A first limitation comes from the assumption that the messenger RNA level can be used as a proxy for the protein activity, which is often not correct (Vogel and Marcotte, 2012).
The epilepsies are a heterogeneous group of neurological disorders and syndromes characterised by recurrent, involuntary, paroxysmal seizure activity, which is often associated with a clinicoelectrical correlate on the electroencephalogram.
For NADPH-dependent cytochrome c reductase activity, which is often used as a readout for superoxide generation, there was no significant decrease in activity in the presence of SOD, indicating that the DH domain of Nox4 generates little if any superoxide.
We also observe the effect of removing GABA inhibitory control of presynaptic glutamate release with the presynaptic GABAB receptor antagonist CGP36216 on morphine-induced increase in locomotor activity, which is often assessed as increased VTA-DA neuron activity at the behavioral level (Vezina, 2004).
The anti-cancer effects of ASA are primarily attributed to its ability to inhibit cyclooxygenase 2 (COX2) activity, which is often up-regulated in breast cancer [ 11, 12], and reduce production of prostaglandin E2 (PGE2), the predominant secreted prostaglandin in breast tumors [ 13].
