The containers should be kept at below until the seedlings appear in about a month, as too high a temperature inhibits germination.

Allosteric modulation of a receptor results from the binding of allosteric modulators at a different site ( a " regulatory site ") from that of the endogenous ligand ( an " active site ") and enhances or inhibits the effects of the endogenous ligand.

Beta blockade, especially of the beta-1 receptor at the macula densa, inhibits renin release, thus decreasing the release of aldosterone.

A study performed at the National institute of Chemistry in Ljubljana, Slovenia, demonstrated that EGCG from green tea inhibits an essential bacterial enzyme gyrase by binding to the ATP binding site of the B subunit.

The primary difficulty in underwater camera usage is, of course, sealing the camera from water at high pressure, while maintaining the ability to operate it < The diving mask also inhibits the ability to view the camera image and to see the monitoring screen clearly through the camera housing.

Additionally MMH inhibits the chemical transformation of folic acid into its active form, folinic acid, this can be treated by folinic acid given at 20 – 200 mg daily.

Hydramethylnon inhibits mitochondrial energy production and has delayed action, with death generally not occurring for at least 24 hrs after consumption of the bait.

In every insect tested, at least one of the three types of Allatostatin inhibits the biosynthesis of juvenile hormone.

On the converse, UTP binding leads to enhanced affinity for CTP at the high-affinity sites and inhibits enzyme activity by up to 95 %, while CTP binding alone inhibits activity to 50 % to 70 %.

* Dendrotoxin 1, which inhibits the K < sup >+</ sup > channels at the pre and post-synaptic level in the intestinal smooth muscle.

Subsequent clinical trials led by Dr. Brian J. Druker at Oregon Health & Science University in collaboration with Dr. Charles Sawyers and Dr. Moshe Talpaz demonstrated that STI-571 inhibits proliferation of BCR-ABL-expressing hematopoietic cells.

It also comes out at times that Lois has developing feelings for Clark, although she inhibits or denies them most of the time.

Additionally MMH inhibits the chemical transformation of folic acid into its active form, folinic acid, this can be treated by folinic acid given at 20 – 200 mg daily.

The cause of the syndrome is a mutation in the PTCH1 tumor-suppressor gene at chromosome 9q22. 3, which inhibits the hedgehog signaling pathway.

It was at that time known that milk fermented with lactic-acid bacteria inhibits the growth of proteolytic bacteria because of the low pH produced by the fermentation of lactose.

Steric hindrance resulting from branching at the α-carbon of a 3-substituted thiophene inhibits polymerization.

Some of the diverging air moves to the poles where air mass subsidence inhibits cloud formation and leads to the creation of the polar areas of high pressure.

In addition, high relative humidity inhibits evaporative cooling by humans.

showed that activated monocytes, which is the case in sepsis, express high levels of PD-1 and that triggering monocytes-expressed PD-1 by its ligand PD-L1 induces IL-10 production which inhibits CD4 T-cell function.

The stomach's high acidity inhibits the breakdown of carbohydrates within it.

In blood plasma, haptoglobin binds free hemoglobin ( Hb ) released from erythrocytes with high affinity and thereby inhibits its oxidative activity.

Progesterone, similarly to androgens and estrogens through their own respective receptors, inhibits the secretion of follicle-stimulating hormone ( FSH ) and luteinizing hormone ( LH ) via activation of the progesterone receptor as a form of negative feedback on the hypothalamic-pituitary-gonadal ( HPG ) axis in order to help prevent sex hormone levels from getting too high.

The high pressure cell inhibits rainfall and generates northwesterly air flow.

Additionally, in high doses it weakly inhibits the reuptake of dopamine, with recent evidence showing that the norepinephrine transporter also transports some dopamine as well, since dopamine is inactivated by norepinephrine reuptake in the frontal cortex, which largely lacks dopamine transporters: therefore, venlafaxine can increase dopamine neurotransmission in this part of the brain.

# Dissolved oxygen increases the redox potential of a solution, and high redox potential inhibits the growth of some strict anaerobes.

Patients about to receive chemotherapy for a cancer with a high cell turnover rate, especially lymphomas and leukemias, should receive prophylactic oral or IV allopurinol ( a xanthine oxidase inhibitor, which inhibits uric acid production ) as well as adequate IV hydration to maintain high urine output (> 2. 5 L / day ).

Even though the original concept of ' high trust ' and ' low trust ' societies may not necessarily hold, it has been widely accepted and demonstrated that social trust benefits the economy and that a low level of trust inhibits economic growth.

Dipyridamole ( trade names Persantine, Antistenocardin ) is a drug that inhibits thrombus formation when given chronically and causes vasodilation when given at high doses over a short time.

Vegetarian diets may also have a high ratio of O6FA to O3FA, which inhibits the conversion of short-chain fatty acids such as alpha-Linolenic acid ( ALA ), found in most vegetarian O3FA sources, to EPA and DHA.

If drug A is metabolized by a cytochrome P450 enzyme and drug B inhibits or decreases the enzyme ’ s activity, then drug A will remain with high levels in the plasma for longer as its inactivation is slower.

While all the causes are not clear, a major cause is a chemical imbalance in vitamins and minerals which inhibits the uptake of calcium, which often occurs subsequent to feeding commercially produced food treats or a high proportion of pellets in the diet.

BZP has a high affinity action at the alpha2-adrenoreceptor, it is an antagonist at the receptor, like yohimbine, which inhibits negative feedback, causing an increase in released noradrenaline.
