Abstract: This application provides a receiving module, a packaging structure, a printed circuit board, and an electronic device, which can mitigate a problem that application scenarios of a front-end receiving module of an existing GNSS receiver are limited. The receiving module includes a first filtering unit, an amplifying unit, and a control element. When the amplifying unit operates in a first mode, the first end of the amplifying unit acts as a signal input end, and in this way, the first filtering unit acts as a front filtering unit. When the amplifying unit operates in a second mode, the first end of the amplifying unit acts as a signal output end, and in this way, the first filtering unit acts as a rear filtering unit.

Abstract: The present disclosure relates to the technical field of gene engineering, and in particular, to use of miR-22-3p in promoting the differentiation of yak myoblasts. miR-22-3pmimic can significantly promote the expression of miR-22-3p, and can also significantly increase the expression of differentiation marker genes MYF5 and MYOD at the mRNA and protein levels. miR-22-3p inhibitor can significantly inhibit the expression of miR-22-3p, and can significantly promote the expression of MYF5 and MYOD at the mRNA and protein levels. miR-22-3p mimic can significantly promote the formation of myotubes, while miR-22-3p inhibitor can significantly inhibit the formation of myotubes. The above results indicate that miR-22-3p has a promoting effect in the differentiation process of myoblasts.

Abstract: Stable nanoemulsions of a terpene-rich cannabidiol by-product (TP) and/or its distillate (DTP) can be used to effectively make pesticides, herbicides, and other bioactive products. A terpene-rich by-product (TP) can be provided, suitably by isolation from a commercial cannabidiol production process. The enriched terpene distillate (DTP) can be obtained from steam distillation of some or all of the TP. The TP and/or DTP can be combined with a surfactant to form an emulsion, which can then be sonicated to form the stable nanoemulsion. It has been discovered that the formulation of stable nanoemulsions using the terpene by-products as the lipophilic phase can effectively deliver desired levels of bioactivity while overcoming or mitigating the known drawbacks of high lipophilicity, high volatility, and propensity to thermal and oxidative degradation, all of which can lead to reduced efficacy.
