An interesting feature of at least one group of slow-cycling cells is their ability to retain electrophiles that bind to DNA; thus they have been termed carcinogen-retaining cells. These slow-cycling cells are located in the basal layer of the epidermis and may play a role in the initial ...
In sinus node dysfunction, the sinus node fails to function as the dominant pacemaker of the heart or performs abnormally slowly, resulting in a variety of arrhythmias. These arrhythmias may include profound sinus bradycardia, sinus pause or arrest, sinus node exit block, slow junctional escape bea...
An additional PSEA for ASD-risk/related gene sets revealed patterns that are opposite to those observed in ASD40(termed reverse-ASD) in synaptosomal DEPs but not in total DEPs (Supplementary Fig.12a-c; Supplementary Datasets5and6). It included positive enrichments for ASD-risk gene sets (i....
An improved Heap Based Optimizer (HBO) algorithm, termed 𝐵_𝐻𝐵𝑂B_HBO, is proposed for the feature selection problem The proposed improved version was tested on 20 datasets, in which 8 belong to a considerably high-dimensional class. The performance of the meta-heuristic algorithms on ...
The system contains a heart-rate sensor embedded in the seat belt. Upon accident detection, the system reports the accident to emergency services through Wi-Fi. The limitation of the system is that seat belt must be worn to record heartbeats. An Accident Detection and Classification (ADC) ...
Answer to: An individual with a smaller heart would most likely have: a. a higher heart rate b. a smaller stroke volume c. a lower heart rate ...
This process is called substrate-supported catalysis. The transformation is indeed still rather slow, but the specificity of this mutant is distinctly enhanced: The -Phe–Ala–His–Phe- sequence is cleaved 200 times faster than any of the other -Phe–Ala–X–Phe- sequences. ...
diabetic mothers are abnormally low. This hypomagnesaemia affects the foetus and may cause congenital malformations and early neonatal hypocalcaemia. Treatment entails a diet, then if the glycaemia is not regulated and exceeds 7.8 mmol/l after a meal, the administering of insulin becomes necessary...
These cells, termed ectopic pacemakers, can be found in the atriovertricular junction and in the His-Purkinje system. The normal rate of impulse initiation by these ectopic pacemakers is less than that of the sinus node and therefore they do not normally initiate the heart beat. However, ...
That portion of the population (at least 1%) bearing the variant CYP gene and expressing an abnormal form of the CYP enzyme may metabolize CYP substrates abnormally, though occasionally the expression of variant forms of CYP enzymes does not lead to unusual rates of substrate metabolism. Often, ...
