Positive feedback systems are unusual in biology, as they terminate with some cataclysmic, explosive event. A good example of a positive feedback system involves oxytocin and its other effect: causing contraction of uterine muscle during childbirth (Fig. 1.51). In this case the stimulus for ...
Fig. 6: HIF2α enhances PVT1 transcription to form a positive feedback regulatory loop. A A schematic diagram of HRE located in the enhancer of PVT1. B The RNA level of PVT1 was significantly reduced in HIF2α-silencing 786-O cells and increased in HIF2α-overexpressing 769-P cells. ...
Liver metastasis is the leading cause of death in patients with colorectal cancer (CRC). Emerge evidence suggests that circular RNA (circRNA) is a pivotal player in cancer progression. However, its role in CRC liver metastasis remains largely unknown. Ci
IL-33 is a danger signal that binds to its receptor ST2L to promote tumor progression. This study identifies the IL-33/ST2L positive-feedback loop and the trafficking of ST2L membrane presentation in macrophages that contribute to lung tumor progression.
A system and method provide feedback to a subject regarding compliance to a positive airway pressure support therapy regime. The feedback is provided to the subject in real-time (or near real-time). The feedback indicates to the subject whether a usage goal has been achieved. The usage ...

Methods A sample of 176 Flemish children (44.3% boys, 913 years) received either person-oriented, process-oriented or neutral positive feedback after a set of easy motor tasks in which they succeeded. Next, children engaged in motor tasks that were too difficult for their age so that they ...
Its denial in the recent literature is briefly documented and various dimensions of this denial are specified. After a brief historical survey of research on adult corrections of children's speech, verbatim evidence of maternal corrective feedback is presented for the following categories of filial ...
Recent studies in cognitive neuroscience have provided evidence for the importance of positive feedback or successful experiences on behavioral changes. This chapter explores three examples in which positive feedback or successful experiences modulate neural function or behavioral outcomes: (1) In a visual...
to regulate physiological tissue remodeling41. Therefore, we can infer that LAMB3+ basal keratinocytes may enhance repigmentation by exerting an influence on the skin microenvironment within the whole epidermal melanin unit, and signaling on melanocytes can also deliver positive feedback in this ...
