Here are 22 examples "a decrease in" there used in a sentence.

1. Conditionally pathogenic bacteria are only pathogenic under certain conditions, such as a wound that allows for entry into the blood, or a decrease in immune function
2. Very often, sarcoidosis presents as a restrictive disease of the lungs, causing a decrease in lung volume and decreased compliance ; hence, chest X-ray and other methods are used to assess the severity or rule out pulmonary disease
3. Maternal anemia in which smoking has also been implicated is another factor associated with IH / BA. Smoking by expectant mothers causes a decrease in maternal nucleated red blood cells, thereby reducing the amount of red blood cells available for oxygen transport
4. Restrictive lung diseases are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and / or oxygenation. Pulmonary function test demonstrates a decrease in the forced vital capacity
5. One study claims, in preliminary results, that "laptops on the lap near the testicles may result in decreased male fertility". Another small sample study (15 males and 15 females) found a decrease in the P300 event-related potential (ERP) for male but not female subjects while engaging in a working memory oriented linguistic task during Wi-Fi exposure
6. Research concerning the effects of pornography is inconclusive on the issue of crime. Some studies support the contention that the viewing of pornographic material may increase rates of sexual crimes, while others have shown no effects, or a decrease in the rates of such crimes. However, most of these studies focus on various correlations, and correlation does not imply causation
7. The glomus cell senses a decrease or rise in blood oxygen levels in the carotid artery, and potassium ion-gates close, causing calcium to flow into the cytosol of the cell, releasing continual signal which is sent via cranial nerves IX and X, from the peripheral chemoreceptors to the brainstem. With a decrease in arterial oxygen tension and content or drop in plasma pH, the signal intensifies, and results in an increase in ventilation rate
8. In the first week, the temperature rises slowly, and fever fluctuations are seen with relative bradycardia, malaise, headache, and cough. A bloody nose is seen in a quarter of cases, and abdominal pain is also possible. There is a decrease in the number of circulating white blood cells (leukopenia) with eosinopenia and relative lymphocytosis; blood cultures are positive for Salmonella typhi or paratyphi. The Widal test is negative in the first week
9. In March 2013, Apple released an updated version of the third generation Apple TV containing a smaller, single core version of the A5 processor, and with no stacked RAM in the package. The chip is very small, just 6.1×6.2 mm, but as the decrease in size is not due to a decrease in feature size (it is still on a 32 nm fabrication process), this indicates that this A5 revision is of a new design. Markings tell that it's named APL7498, and in software, the chip is called S5L8947
10. The molecular mechanism of pulmonary arterial hypertension is not known yet, but it is believed that the endothelial dysfunction results in a decrease in the synthesis of endothelium-derived vasodilators such as nitric oxide and prostacyclin. Moreover, there’s a stimulation of the synthesis of vasoconstrictors such as thromboxane and vascular endothelial growth factor (VEGF) . These results in a severe vasoconstriction and smooth muscle and adventitial hypertrophy characteristic of patients with PAH
11. The disease typically limits the amount of air drawn into the lungs, but produces higher than normal expiratory flow ratios. The vital capacity is decreased, and most of this air can be blown out in the first second. This means the FEV1 / FVC ratio is increased from the normal of about 80%, to 90%. Obstructive lung changes, causing a decrease in the amount of air that can be exhaled, may occur when enlarged lymph nodes in the chest compress airways or when internal inflammation or nodules impede airflow
12. Anemia is a decrease in number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency. Because hemoglobin (found inside RBCs) normally carries oxygen from the lungs to the capillaries, anemia leads to hypoxia (lack of oxygen) in organs. Since all human cells depend on oxygen for survival, varying degrees of anemia can have a wide range of clinical consequences
13. Oxyhemoglobin is formed during physiological respiration when oxygen binds to the heme component of the protein hemoglobin in red blood cells. This process occurs in the pulmonary capillaries adjacent to the alveoli of the lungs. The oxygen then travels through the blood stream to be dropped off at cells where it is utilized as a terminal electron acceptor in the production of ATP by the process of oxidative phosphorylation. It does not, however, help to counteract a decrease in blood pH. Ventilation, or breathing, may reverse this condition by removal of carbon dioxide, thus causing a shift up in pH
14. The Bohr effect is a physiological phenomenon first described in 1904 by the Danish physiologist Christian Bohr, stating that hemoglobin's oxygen binding affinity is inversely related both to acidity and to the concentration of carbon dioxide. That is to say, a decrease in blood pH or an increase in blood CO2 concentration will result in hemoglobin proteins releasing their loads of oxygen and a decrease in carbon dioxide or increase in pH will result in hemoglobin picking up more oxygen. Since carbon dioxide reacts with water to form carbonic acid, an increase in CO2 results in a decrease in blood pH
15. National Screen Service contracts required that trailers be returned or destroyed, however it required no proof of destruction and depositing them in a waste bin counted. A market for trailers evolved as it became clear that some had a commercial value to collectors. Many of the trailers for films like the Star Wars series reported as ' destroyed ' were taken back out of the bin and sold by cinema staff. As they cost about $60 each to make (1981 estimate) and were hired to the cinema for $10, such losses led to NSS increasing its rental charges, which lead to a decrease in the number of trailers rented and shown to audiences
16. Advertising Age reported that movie studio executives were convinced the release of Halo 3 harmed box office receipts; the week's take was 27% less than the previous year's yield. While some executives decided the disparity in estimated and actual gross for films like The Heartbreak Kid was due more to the film's poor reception, other analysts believed that "the audience on [Halo 3] is the 18-to-34 demographic, similar to what you ' d see in cinemas" and that this led to a decrease in receipts. Later research suggested that the Halo 3 players still watched the same amount of television and movies, regardless of the time they spent playing the game
17. Clinicians have also noticed positive results during the use of human interferon and glycyrrhizin. No compounds have yielded inhibitory results of any significance. The HIV protease inhibitors ritonavir and saquinavir did not show any inhibitory effect at nontoxic levels. Iminocyclitol 7 has been found to have an inhibitory effect on SARS-CoV in that it disrupts the envelope glycoprotein processing. Iminocyclitol 7 specifically inhibits the production of human fucosidase and in vitro trials yielded promising results in the treatment of SARS, yet one problem exists. A deficiency of fucosidase can lead to a condition known as fucosidosis in which there is a decrease in neurological function
18. In COPD, there is an increase in airway resistance, shown by a decrease in the forced expiratory volume in 1 second measured by spirometry. COPD is defined as a forced expiratory volume in 1 second to forced vital capacity ratio (FEV1 / FVC) that is less than 0.7. The residual volume, the volume of air left in the lungs following full expiration, is often increased in COPD, as is the total lung capacity, while the vital capacity remains relatively normal. The increased total lung capacity (hyperinflation) can result in the clinical feature of a "barrel chest" - a chest with a large front-to-back diameter that occurs in some individuals with COPD. Hyperinflation can also be seen on a chest x-ray as a flattening of the diaphragm
19. Historically, males have had higher infant mortality rates than females. The difference between male and female infant mortality rates have been dependent on environmental, social, and economic conditions. More specifically, males are biologically more vulnerable to infections and conditions associated with prematurity and development. Before 1970, the reasons for male infant mortality were due to infections, and chronic degenerative diseases. However, since 1970, certain cultures emphasizing males has led to a decrease in the infant mortality gap between males and females. Also, medical advances have resulted in a growing number of male infants surviving at higher rates than females due to the initial high infant mortality rate of males
20. In the Welsh Borders, the first evidence of wildfire is rhyniophytoid plant fossils preserved as charcoal, dating to the Silurian period. Smoldering surface fires started to occur sometime before the Early Devonian period 405 million years ago. Low atmospheric oxygen during the Middle and Late Devonian was accompanied by a decrease in charcoal abundance. Additional charcoal evidence suggests that fires continued through the Carboniferous period. Later, the overall increase of atmospheric oxygen from 13% in the Late Devonian to 30-31% by the Late Permian was accompanied by a more widespread distribution of wildfires. Later, a decrease in wildfire-related charcoal deposits from the late Permian to the Triassic periods is explained by a decrease in oxygen levels
21. Granting women employment raises their status and autonomy. Having a gainful employment can raise the perceived worth of females. This can lead to an increase in the number of women getting an education and a decrease in the number of female infanticide. In the social modernization perspective, education leads to development. Higher number of skilled workers means more earning and further economic growth. According to the economic modernization perspective, this is one type economic growth viewed as the driving force behind the increase in development and standard of living in a country. This is further explained by the modernization theory- economic development promotes physical wellbeing. As economy rises, so do technological advances and thus, medical advances in access to clean water, health care facilities, education, and diet. These changes may decrease infant mortality
22. Peer groups are essential to social and general development. High quality friendships may enhance children's development regardless of the characteristics of those friends. As children begin to gain bonds with various people and create friendships with them, it will later on help them when they are adolescent. This sets up the framework for adolescence and peer groups. Peer groups are especially important during adolescence, a period of development characterized by a dramatic increase in time spent with peers and a decrease in adult supervision. Adolescents also associate with friends of the opposite sex much more than in childhood and tend to identify with larger groups of peers based on shared characteristics. It is also common for adolescents to use friends as coping devices in different situations. A three factor structure of dealing with friends including avoidance, mastery, and nonchalance has shown that adolescent's use friends as coping devices with social stresses
