Interbase-FRET binding assay for pre-microRNAs.

Sci Rep 2021 Apr 30;11(1):9396. Epub 2021 Apr 30.

Department of Chemistry and Molecular Biology, University of Gothenburg, 412 96, Gothenburg, Sweden.

The aberrant expression of microRNAs (miRs) has been linked to several human diseases. A promising approach for targeting these anomalies is the use of small-molecule inhibitors of miR biogenesis. These inhibitors have the potential to (i) dissect miR mechanisms of action, (ii) discover new drug targets, and (iii) function as new therapeutic agents. Read More

Differential diagnosis of brain lesions in a metastatic endometrial carcinosarcoma patient.

Ecancermedicalscience 2021 9;15:1182. Epub 2021 Feb 9.

Division of Advanced Internal Medicine, Department of Medicine, National University Hospital, National University Health System, 1E Kent Ridge Road, Singapore 119228, Singapore.

The differential diagnosis of ring-enhancing brain lesions in a patient with metastatic malignancy may initially seem straightforward, and easily attributed to brain metastases. On rare occasions, the physician needs to avoid anchoring bias by re-evaluating the entire clinical context in which these ring-enhancing brain lesions are found. We report a case of cerebral toxoplasmosis mimicking brain metastases in a patient with metastatic cancer and without a prior history of human immunodeficiency virus. Read More

Green-tea-synthesized silver nanoparticles as a sensing platform for determination of tetracycline in honey samples.

J Sci Food Agric 2021 Feb 20. Epub 2021 Feb 20.

INQUISUR, Departamento de Química, Universidad Nacional del Sur (UNS)-CONICET, Bahía Blanca, Argentina.

Background: Silver nanoparticles (AgNPs) can be easily obtained in aqueous solution by chemical reduction using appropriate reducing agents and stabilizers. The development of environmentally friendly methods using non-toxic solvents and reagents has become an alternative for the synthesis of these particles and their future application as sensor probes for agricultural products. In this work, a straightforward method based on green tea extracts as reducing and capping agent is proposed for the synthesis of AgNPs, followed by their evaluation as a sensing platform for determination of tetracycline in honey samples.

Consensus Report by the Italian Academy of Osseointegration on the Use of Antibiotics and Antiseptic Agents in Implant Surgery.

Int J Oral Maxillofac Implants 2021 Jan-Feb;36(1):103-105

Purpose: Beneficial aspects of short and ultrashort antibiotic administration protocols could be clinically correlated to the reduced side effects on the gastrointestinal microflora. The aim of this Consensus Conference was to establish the necessity of an antibiotic prophylaxis and its dosage to reduce the risk of early implant failure in healthy (ASA 1 or 2), periodontally healthy patients, undergoing basic dental implant surgery (straightforward cases). Additionally, the need for an antiseptic protocol, used before and after the implant surgery, was evaluated. Read More

Mussel-Inspired Polymeric Coatings to Realize Functions from Single and Dual to Multiple Antimicrobial Mechanisms.

ACS Appl Mater Interfaces 2021 Jan 5;13(2):3089-3097. Epub 2021 Jan 5.

College of Materials Science & Engineering, Zhejiang University of Technology, Hangzhou 310014, P. R. China.

Numerous efforts to fabricate antimicrobial surfaces by simple yet universal protocols with high efficiency have attracted considerable interest but proved to be particularly challenging. Herein, we designed and fabricated a series of antimicrobial polymeric coatings with different functions from single to multiple mechanisms by selectively utilizing diethylene glycol diglycidyl ether (PEGDGE), polylysine, and poly[glycidylmethacrylate--3-(dimethyl(4-vinylbenzyl)ammonium)propyl sulfonate] (poly(GMA--DVBAPS)) via straightforward mussel-inspired codeposition techniques. Bactericidal polylysine endowed the modified surfaces with a high ability (∼90%) to kill attached bacteria, while PEGDGE components with unique surface hydration prevented bacterial adhesion, avoiding the initial biofilm formation.

Exp Hematol 2021 01 11;93:61-69.e4. Epub 2020 Nov 11.

Department of Internal Medicine III, Ulm University Hospital, Ulm, Germany; Department for Hematology, Oncology and Tumor Immunology, Charité-Universitätsmedizin Berlin, Campus Benjamin Franklin, Berlin, Germany. Electronic address:

The immunomodulatory drugs (IMiDs) thalidomide, lenalidomide, and pomalidomide are approved drugs for the treatment of multiple myeloma. IMiDs induce cereblon (CRBN) E3 ubiquitin ligase-mediated ubiquitination and degradation of Ikaros transcription factors Ikaros (IKZF1) and Aiolos (IKZF3), which are essential for multiple myeloma. However, because of a single amino acid substitution of valine to isoleucine in mouse CRBN at position 391, mice are not susceptible to IMiD-induced degradation of neosubstrates. Read More

A Comprehensive Toolkit for Quick and Easy Visualization of Marker Proteins, Protein-Protein Interactions and Cell Morphology in .

Front Plant Sci 2020 15;11:569194. Epub 2020 Oct 15.

Institute for Plant Sciences, Faculty of Mathematics and Natural Sciences, University of Cologne, Cologne, Germany.

Even though stable genomic transformation of sporelings and thalli of is straightforward and efficient, numerous problems can arise during critical phases of the process such as efficient spore production, poor selection capacity of antibiotics or low transformation efficiency. It is therefore also desirable to establish quick methods not relying on stable transgenics to analyze the localization, interactions and functions of proteins of interest. The introduction of foreign DNA into living cells via biolistic mechanisms has been first reported roughly 30 years ago and has been commonly exploited in established plant model species such as or .

Oral Antibiotic Treatment Options for Acne Vulgaris.

Authors:
Hilary Baldwin

J Clin Aesthet Dermatol 2020 Sep 1;13(9):26-32. Epub 2020 Sep 1.

Dr. Baldwin is the Medical Director of the Acne Treatment and Research Center in Brooklyn, New York and is with Rutgers Robert Wood Johnson Medical Center in New Brunswick, New Jersey.

Acne vulgaris is the most common dermatological disease in the United States, affecting up to 85 percent of teenagers. While the American Academy of Dermatology has established guidelines regarding acne treatment in general, the variability among acne treatments, even within a given class, prevents establishment of a straightforward regimen. For example, moderate to severe acne is generally treated with an oral antibiotic, although several options are available-both across and within antibiotic classes. Read More

Department of Chemistry and Biochemistry, Stephenson Life Sciences Research Center, University of Oklahoma, 101 Stephenson Parkway, Norman, Oklahoma 73019, United States.

Bacterial biofilms, often impenetrable to antibiotic medications, are a leading cause of poor wound healing. The prognosis is worse for wounds with biofilms of antimicrobial-resistant (AMR) bacteria, such as methicillin-resistant (MRSA), methicillin-resistant (MRSE), and multi-drug resistant (MDR-PA). Resistance hinders initial treatment of standard-of-care antibiotics. Read More

URD Agro-Biotechnologies Industrielles (ABI), CEBB, AgroParisTech, 51110, Pomacle, France.

Naturally occurring sinapine was successfully synthesized through a proline-mediated Knoevenagel-Doebner condensation in ethanol. This synthetic process involving biobased syringaldehyde, Meldrum's acid, and choline chloride offers a sustainable alternative to the existing low-yield pathways. This two-step strategy gives access to sinapine in a 52% overall yield and has been implemented in the synthesis of sinapine analogues, using 4-hydroxybenzaldehyde, 3,4-dihydroxybenzaldehyde, and vanillin as precursors, giving target molecules with 34-61% overall isolated yields.
