Psoriasis is a T cell mediated chronic inflammatory skin disease affecting about 2% of the population worldwide. Recently has established the central role of IL-23/Th17 immune axis in the pathogenesis of psoriasis and different subclasses of T cells including Th1 and Th17 cells are involved in initiation and amplification of the skin inflammation process, in addition, in cases of recurrent psoriasis, Th22 cells play the role of memory cells with the help of Th9 cells, which are also important in this process. The main goal was to evaluate the ratio of T cell profile and IL23/Th17 axis by evaluating IL17A, IL22, IL9 in peripheral blood of persons with moderate to severe plaque psoriasis. Read More

The Fate of Sutures Post Rotator Cuff Repair.

J Shoulder Elbow Surg 2021 May 5. Epub 2021 May 5.

Department/ Institution: Orthopaedic Research Institute, St. George Hospital Campus, University of New South Wales, Sydney, NSW, Australia. Electronic address:

Background: Ultrasound imaging has been widely used as a diagnostic tool for rotator cuff tears. Several studies have explored the changes in rotator cuff tendon morphology after arthroscopic cuff repair, however none have addressed the fate of sutures. The aim of this study was to determine: (1) if the sutures migrate through the tendon during the postoperative healing period in patients who have had arthroscopic rotator cuff repair, (2) if the sutures do migrate, the time point at which it does and, (3) if the quality of the tendon, in terms of tendon stiffness, modulus of elasticity, bursal thickness and anatomical footprint, affects suture migration.

Using Pressure Mapping to Optimize Hospital-Acquired Pressure Injury Prevention Strategies in the Burn Intensive Care Unit.

J Burn Care Res 2021 May 8. Epub 2021 May 8.

Department of Plastic & Reconstructive Surgery, Johns Hopkins Hospital, Baltimore, Maryland, USA.

Although prior studies have demonstrated the utility of real-time pressure mapping devices in preventing pressure ulcers, there has been little investigation of their efficacy in burn intensive care unit (BICU) patients, who are at especially high risk for these hospital-acquired injuries. This study retrospectively reviewed clinical records of BICU patients to investigate the utility of pressure mapping data in determining the incidence, predictors and associated costs of hospital-acquired pressure injuries. Of 122 patients, 57 (47%) were studied prior to implementation of pressure mapping and 65 (53%) were studied after implementation. Read More

Steven J Lehotay

Anal Bioanal Chem 2021 May 7. Epub 2021 May 7.

U.S. Department of Agriculture, Agricultural Research Service, Eastern Regional Research Center, 600 East Mermaid Lane, Wyndmoor, PA, 19038, USA.

Ultrahigh-performance liquid chromatography (UHPLC) coupled with triple quadrupole tandem mass spectrometry (MS/MS) is one of the most powerful tools for the multiclass, multiresidue analysis of veterinary drugs, pesticides, mycotoxins, and other chemical contaminants in foods and other sample types. Until approximately 2010, commercial MS/MS instruments using multiple reaction monitoring (MRM) were generally limited to minimum dwell (and inter-dwell) times of 10 ms per ion transition. To achieve the needed accuracy and detection limits for hundreds of targeted analytes, older UHPLC-MS/MS methods typically acquired only two ion transitions per analyte (yielding only one ion ratio for qualitative identification purposes), which is still the norm despite technological advancements.

J Pharmacol Exp Ther 2021 May 7. Epub 2021 May 7.

Pharmaceutical Sciences, University at Buffalo, United States

The drug of abuse, γ-hydroxybutyric acid (GHB), is commonly co-ingested with ethanol, resulting in a high incidence of toxicity and death. Our laboratory has previously reported that GHB is a substrate for the monocarboxylate transporters (MCT), necessary for its absorption, renal clearance, and tissue distribution, including across the blood-brain barrier. Our goal was to investigate the drug-drug interaction (DDI) between GHB-ethanol and evaluate MCT1 inhibition as a strategy to reverse toxicity. Read More

Internal loading of phosphate in rivers reduces at higher flow velocity and is reduced by iron rich sand application: an experimental study in flumes.

Water Res 2021 Apr 18;198:117160. Epub 2021 Apr 18.

Division of Soil and Water Management, Department of Earth and Environmental Sciences, KU Leuven, Kasteelpark Arenberg 20 bus 2459, 3001 Leuven, Belgium.

Many lowland regions are afflicted with high phosphorus (P) peaks in rivers during the summer months. Static incubations of sediments have shown that reductive dissolution of ferric iron (Fe(III)) minerals in the sediment explain these P peaks. This study was set up to identify if that mechanism also dominates in a dynamic system, thereby testing the roles of water flow velocity and sediment Fe/P ratio. Read More

Role of central kisspeptin and RFRP-3 in energy metabolism in the male Wistar rat.

J Neuroendocrinol 2021 May 7:e12973. Epub 2021 May 7.

Netherlands Institute for Neuroscience (NIN), Amsterdam, The Netherlands.

Kisspeptin (Kp) and (Arg)(Phe) related peptide 3 (RFRP-3) are two RF-amides acting in the hypothalamus to control reproduction. In the past 10 years, it has become clear that, apart from their role in reproductive physiology, both neuropeptides are also involved in the control of food intake, as well as glucose and energy metabolism. To investigate further the neural mechanisms responsible for these metabolic actions, we assessed the effect of acute i. Read More
