It is the hope of the international faculty that the information that emerged from the summit can be used by others to successfully implement IV compounding robotics in their sterile products areas to maximize patient safety. The summit also served as a call to action for pharmacy leaders, drug manufacturers, and robotic companies to develop a safer, more efficient future for patients by working together to optimize the development and operation of IV robotics.

During their growth in soil, plant roots are often challenged by various biotic or abiotic stresses, resulting in damage to the SCN. This can be repaired by the reconstruction of a functional SCN. Previous studies examining the SCN's reconstruction often introduce physical damage including laser ablation or surgical excision. In this study, we performed a time-course observation of the SCN reconstruction in pWOX5icals3m roots, an inducible system that causes non-invasive SCN differentiation upon induction of estradiol on Arabidopsis (Arabidopsis thaliana) root. We found a stage-dependent reconstruction of SCN in pWOX5icals3m roots, with division-driven anatomic reorganization in the early stage of the SCN recovery, and cell fate specification of new SCN in later stages. During the recovery of the SCN, the local accumulation of auxin was coincident with the cell division pattern, exhibiting a spatial shift in the root tip. In the early stage, division mostly occurred in the neighboring stele to the SCN position, while division in endodermal layers seemed to contribute more in the later stages, when the SCN was specified. The precise re-positioning of SCN seemed to be determined by mutual antagonism between auxin and cytokinin, a conserved mechanism that also regulates damage-induced root regeneration. Our results thus provide time-course information about the reconstruction of SCN in intact Arabidopsis roots, which highlights the stage-dependent re-patterning in response to differentiated quiescent center.
To investigate the function of transient receptor potential melastatin 2 (TRPM2) in vascular reactivity induced by 5-hydroxytryptamine (5-HT) in the aorta during development of atherosclerosis in mice.
Forty mice were randomly divided into 4 groups C57BL/6J on normal diet (C57 + ND), C57BL/6J on high-fat diet (C57 + HFD), apolipoprotein E gene knockout mice (ApoE-/-) on ND (ApoE-/- + ND), and ApoE-/- on HFD (ApoE-/- + HFD). They were fed with a ND or HFD for 16 weeks. Aortic TRPM2 expression and isometric contractions were analyzed.
In the ApoE-/- + HFD group, body weight, blood glucose, and blood lipid concentrations were increased, and aortic plaques were developed. Compared with the other 3 groups, aortic TRPM2 mRNA and protein levels were significantly increased in the ApoE-/- + HFD group (P < 0.01). Aortic reactivity to 5-HT was enhanced in ApoE-/- + HFD mice with lower EC50 values. The enhanced reactivity to 5-HT was significantly inhibited by TRPM2 inhibitors, N-p-amylcinnamoyl anthranilic acid (1 µmol/l) and 2-aminoethyl diphenylborinate (10 µmol/l).
Aortic TRPM2 expression is upregulated in ApoE knockout mice fed with a HFD. Upregulation of TRPM2 enhances 5-HT vascular reactivity during development of atherosclerosis.

To analyze whether the cytochrome P450 enzyme 2C9*3 (CYP2C9*3) and angiotensin II receptor 1 (AGTR1) (1166A>C) gene polymorphisms are associated with the risk of essential hypertension (EH) and the antihypertensive effect of irbesartan.
A total of 2,057 EH patients and 286 healthy controls were enrolled for genotyping in which 598 EH patients were given irbesartan 150 mg/day for 4 weeks. Blood pressure of all subjects were determined before and at the end of 4-week treatment.
There was no significant difference in genotype frequencies of CYP2C9*3 and AGTR1 (1166A>C) between EH and control groups. Subjects with *1*3/*3*3 genotypes of the CYP2C9*3 gene had larger systolic and diastolic blood pressure reductions (34.9 ± 15.5 vs. 29.3 ± 10.2 mm Hg and 22.8 ± 9.0 vs. 19.6 ± 8.5 mm Hg, respectively) compared with the *1*1 genotype. For AGTR1 (1166A>C) polymorphisms, although there was no significant difference among AC, CC, and AA genotypes, male subjects with AC/CC genotypes had larger systolic and diastolic blood pressure reductions (32.3 ± 1.3 vs. 29.3 ± 0.5 mm Hg and 21.6 ± 0.8 vs. 19.4 ± 0.1 mm Hg, respectively, P < 0.05) in response to irbesartan treatment compared with the AA genotype.
Polymorphisms of CYP2C9*3 and AGTR1 (1166A>C) are not significantly different between EH and healthy controls. Male subjects with AC and CC genotypes of AGTR1 (1166A>C) show better antihypertensive effect of irbesartan than the AA genotype.
C) show better antihypertensive effect of irbesartan than the AA genotype.At the surface of many cells is a compendium of glycoconjugates that form an interface between the cell and its surroundings; the glycocalyx. The glycocalyx serves several functions that have captivated the interest of many groups. Given its privileged residence, this meshwork of sugar-rich biomolecules is poised to transmit signals across the cellular membrane, facilitating communication with the extracellular matrix and mediating important signalling cascades. As a product of the glycan biosynthetic machinery, the glycocalyx can serve as a partial mirror that reports on the cell's glycosylation status. The glycocalyx can also serve as an information-rich barrier, withholding the entry of pathogens into the underlying plasma membrane through glycan-rich molecular messages. In this review, we provide an overview of the different approaches devised to engineer glycans at the cell surface, highlighting considerations of each, as well as illuminating the grand challenges that face the next era of 'glyco-engineers'.
