Retention Indices for Frequently Reported Compounds of Plant Essential Oils
Retention Indices for Frequently Reported Compounds of Plant Essential Oils V. I. Babushok,a) P. J. Linstrom, and I. G. Zenkevichb) National Institute of Standards and Technology, Gaithersburg, Maryland 20899, USA (Received 1 August 2011; accepted 27 September 2011; published online 29 November 2011) Gas chromatographic retention indices were evaluated for 505 frequently reported plant essential oil components using a large retention index database. Retention data are presented for three types of commonly used stationary phases: dimethyl silicone (nonpolar), dimethyl sili- cone with 5% phenyl groups (slightly polar), and polyethylene glycol (polar) stationary phases. The evaluations are based on the treatment of multiple measurements with the number of data records ranging from about 5 to 800 per compound. Data analysis was limited to temperature programmed conditions. The data reported include the average and median values of retention index with standard deviations and confidence intervals.

Cytokines and Chemokines in SARS-Cov-2 Infections—Therapeutic Strategies Targeting Cytokine Storm

Although several factors of this infection and its consequences are not completely clear, the presence and involvement of specific chemokines is undoubtedly crucial for the development and progression of COVID-19. Cytokine storm and the often-resulting cytokine release syndrome (CRS) are patho- physiological hallmarks in COVID-19 infections related to its most severe and fatal cases. In this hyperinflammatory event, chemokines and other cytokines are highly upregulated and are therefore not fulfilling their beneficial function in the host response anymore but causing harmful effects. Here, we present the recent views on the involvement of chemokines and selected cytokines in COVID-19 and the therapeutics currently in clinical development targeting or interfering with them, discussing their potentials in the treatment of COVID-19 infections.

TRP Channel Transient Receptor Potential Channels
TRP Channel Transient receptor potential channels TRP Channel (Transient receptor potential channel) is a group of ion channels located mostly on the plasma membrane of numerous human and animal cell types. There are about 28 TRP channels that share some structural similarity to each other. These are grouped into two broad groups: Group 1 includes TRPC ("C" for canonical), TRPV ("V" for vanilloid), TRPM ("M" for melastatin), TRPN, and TRPA. In group 2, there are TRPP ("P" for polycystic) and TRPML ("ML" for mucolipin). Many of these channels mediate a variety of sensations like the sensations of pain, hotness, warmth or coldness, different kinds of tastes, pressure, and vision. TRP channels are relatively non-selectively permeable to cations, including sodium, calcium and magnesium. TRP channels are initially discovered in trp-mutant strain of the fruit fly Drosophila. Later, TRP channels are found in vertebrates where they are ubiquitously expressed in many cell types and tissues. TRP channels are important for human health as mutations in at least four TRP channels underlie disease. www.MedChemExpress.com 1 TRP Channel Antagonists, Inhibitors, Agonists, Activators & Modulators (-)-Menthol (E)-Cardamonin Cat.

Therapeutic Guidelines for Antiretroviral (ARV) Treatment of Adult HIV Infection September 2015
Therapeutic Guidelines for Antiretroviral (ARV) Treatment of Adult HIV Infection September 2015 Prepared by J Montaner (editor), S Guillemi and M Harris (co-editors) on behalf of the Committee for Drug Evaluation and Therapy, British Columbia Centre for Excellence in HIV/AIDS The BC-CfE Therapeutic Guidelines have remained generally consistent but not identical with the IAS-USA Guidelines since 1996. The current Guidelines are consistent with those published by H.F. Günthard et al. in 2014 (Günthard HF, Aberg JA, Eron JJ, et al. Antiretroviral Treatment of Adult HIV Infection: 2014 Recommendations of the International Antiviral Society–USA Panel. JAMA 2014; 312(4):410-425). However, the reader should be aware that the use of antiretroviral drugs for the treatment of HIV infection within the BC-CfE programs is exclusively guided by the 2015 Guidelines as outlined here.

TRP Channels and Migraine: Recent Developments and New Therapeutic Opportunities
pharmaceuticals Review TRP Channels and Migraine: Recent Developments and New Therapeutic Opportunities Silvia Benemei 1 and Greg Dussor 2,* 1 Headache Centre, Careggi University Hospital, Viale Pieraccini 18, 50139 Florence, Italy; silvia.benemei@unifi.it 2 School of Behavioral and Brain Sciences, Center for Advanced Pain Studies, The University of Texas at Dallas, Richardson, TX 75080, USA * Correspondence: [email protected]; Tel.: +1-972-883-2385 Received: 1 March 2019; Accepted: 4 April 2019; Published: 9 April 2019 Abstract: Migraine is the second-most disabling disease worldwide, and the second most common neurological disorder. Attacks can last many hours or days, and consist of multiple symptoms including headache, nausea, vomiting, hypersensitivity to stimuli such as light and sound, and in some cases, an aura is present. Mechanisms contributing to migraine are still poorly understood. However, transient receptor potential (TRP) channels have been repeatedly linked to the disorder, including TRPV1, TRPV4, TRPM8, and TRPA1, based on their activation by pathological stimuli related to attacks, or their modulation by drugs/natural products known to be efficacious for migraine. This review will provide a brief overview of migraine, including current therapeutics and the link to calcitonin gene-related peptide (CGRP), a neuropeptide strongly implicated in migraine pathophysiology. Discussion will then focus on recent developments in preclinical and clinical studies that implicate TRP channels in migraine pathophysiology or in the efficacy of therapeutics. Given the use of onabotulinum toxin A (BoNTA) to treat chronic migraine, and its poorly understood mechanism, this review will also cover possible contributions of TRP channels to BoNTA efficacy. -
