Background This study investigated plasma concentrations of substance P (SP) in patients undergoing general anesthesia (GA) and postoperative nausea and vomiting (PONV). This prospective, observational, cohort study included 23 patients who underwent scheduled surgery under general anesthesia. Blood was collected from the radial artery at predetermined time points (15-30 mins prior anesthesia, ...

As pregnancy advances, prostaglandins (PG) increase in the uterus, leading to elevated uterine contractility. Therefore, regulating the concentration of PG in the uterus can be a key factor for controlling the duration of labor. Since the synthesis of PGs in the uterus is catalyzed by cyclooxygenase-2 (COX-2), devising a tool to regulate the expression of COX-2 could provide a method for treati...

Development of the two putative peptide neurotransmitters, substance P (SP) and somatostatin (SS), were compared in rat dorsal root ganglion (DRG) and spinal cord in vivo. The content of SS in the sixth cervical DRG increased 5-fold during the first 5 weeks of life, rising from 24 pg per ganglion at birth. SP content increased 4.5-fold during the first 5 weeks, from 56 pg per ganglion at birth....

Chaetoceros sp. has been found to possess significant amounts of valuable fucoxanthin, phenolics, and flavonoids, with enormous nutraceutical antioxidant potential. The aim this study was employ ultrasound-assisted extraction determine the properties extracts prepared from tenuissimus using different solvents: Propylene glycol (PG), acetone (AC), methanol (ME), difference ultrasonication times ...

The novel carbon allotrope with particular and unique 2D arrangement of atoms similar to a Cairo pentagonal tiling, interplay $sp^{3}$ $sp^{2}$ hybridized is called Penta-graphene (PG). Previous theoretical investigations have shown that PG monolayer mechanically thermodynamically stable, possessing also large band gap $3.25eV$. This new atom in network (non-coplanar pentagons) the focus this w...

Calcitonin gene-related peptide (CGRP) and substance P are known to play a counterregulatory role in acquired models of salt-dependent hypertension. In contrast, neuronal production of these peptides is decreased in the spontaneously hypertensive rat, which may contribute to the elevated blood pressure. To determine the role played by CGRP and substance P in Dahl-salt hypertension, 4- to 6-week...
