Development and evaluation of raloxifene hydrochloride-loaded subdermal implants using hot-melt extrusion technology.

Int J Pharm 2022 May 18:121834. Epub 2022 May 18.

Department of Pharmaceutics and Drug Delivery, School of Pharmacy, University of Mississippi, University, Mississippi 38677; Pii Center for Pharmaceutical Technology, School of Pharmacy, University of Mississippi, University, Mississippi 38677.

Implantable drug delivery systems are known to provide great patient compliance and allow for controlled delivery of drugs over a prolonged period of time. This study aimed to prepare novel polycaprolactone/polyethylene glycol-based raloxifene hydrochloride subdermal solid cylindrical implants using a single-step hot-melt extrusion (HME) continuous process, for the provision of a sustained and prolonged release of RX-HCl as a cornerstone and alternative treatment and prevention option of osteoporosis, most especially post-menopausal osteoporosis, and invasive breast cancer, while providing better clinical outcomes by circumventing clinical and biopharmaceutical hurdles like first-pass metabolism and patient non-adherence and incompliance associated with the oral dosage forms of raloxifene hydrochloride. The 11-mm co-rotating twin-screw extruder was used to prepare the implants. Read More

Impacts of food waste to sludge ratios on microbial dynamics and functional traits in thermophilic digesters.

Water Res 2022 May 11;219:118590. Epub 2022 May 11.

Environmental Microbiome Engineering and Biotechnology Laboratory, Center for Environmental Engineering Research, Department of Civil Engineering, The University of Hong Kong, Hong Kong SAR, China. Electronic address:

A self-stabilizing microbial community lays the foundation of the efficient biochemical reactions of the anaerobic digestion (AD) process. Despite extensive profiling of microbial community dynamics under varying operating parameters, the effects of food waste (FW) to feeding sewage sludge (FSS) ratios on the microbial assembly, functional traits, and syntrophic interspecies interactions in thermophilic microbial consortia remain poorly understood. Here, we investigated the long-term impacts of the FW: FSS ratio on the thermophilic AD microbiome using genome-centric metagenomics. Read More

Current and Emerging Strategies to Inhibit Type 2 Inflammation in Atopic Dermatitis.

Dermatol Ther (Heidelb) 2022 May 21. Epub 2022 May 21.

Sanofi, 450 Water Street, Cambridge, MA, USA.

Type 2 immunity evolved to combat helminth infections by orchestrating a combined protective response of innate and adaptive immune cells and promotion of parasitic worm destruction or expulsion, wound repair, and barrier function. Aberrant type 2 immune responses are associated with allergic conditions characterized by chronic tissue inflammation, including atopic dermatitis (AD) and asthma. Signature cytokines of type 2 immunity include interleukin (IL)-4, IL-5, IL-9, IL-13, and IL-31, mainly secreted from immune cells, as well as IL-25, IL-33, and thymic stromal lymphopoietin, mainly secreted from tissue cells, particularly epithelial cells.

In Vitro Studies on Accelerating the Degradation and Clearance of Amyloid-β Fibrils by an Antiamyloidogenic Peptide.

ACS Macro Lett 2015 Apr 9;4(4):339-342. Epub 2015 Mar 9.

Key Laboratory of Functional Polymer Materials of Ministry of Education, Institute of Polymer Chemistry, Collaborative Innovation Center of Chemical Science and Engineering (Tianjin), Nankai University, Tianjin 300071, China.

The clearance of overloaded amyloid-β (Aβ) species, especially the toxic aggregates, was thought to be an attractive and promising strategy for Alzheimer's disease (AD) therapy in the past decade. In this work, an active Aβ inhibitor decapeptide RR was used to transform mature Aβ fibrils (fAβ) into nanorod-like Aβ assemblies (rAβ) as well as loosen the β-structure of rAβ. Compared with fAβ, rAβ could be engulfed by PC12 cells more efficiently and showed a 1. Read More

Ambient air pollutants increase the risk of immunoglobulin E-mediated allergic diseases: a systematic review and meta-analysis.

Environ Sci Pollut Res Int 2022 May 20. Epub 2022 May 20.

Department of Epidemiology and Biostatistics, School of Public Health, Anhui Medical University, Hefei, Anhui, China.

Immunoglobulin E (IgE)-mediated allergic diseases, including eczema, atopic dermatitis (AD), and allergic rhinitis (AR), have increased prevalence in recent decades. Recent studies have proved that environmental pollution might have correlations with IgE-mediated allergic diseases, but existing research findings were controversial. Thus, we performed a comprehensive meta-analysis from published observational studies to evaluate the risk of long-term and short-term exposure to air pollutants on eczema, AD, and AR in the population (per 10-μg/m increase in PM and PM; per 1-ppb increase in SO, NO, CO, and O).

A History of Senile Plaques: From Alzheimer to Amyloid Imaging.

Thomas G Beach

J Neuropathol Exp Neurol 2022 May;81(6):387-413

From the Civin Laboratory for Neuropathology, Banner Sun Health Research Institute, Sun City, Arizona, USA.

Senile plaques have been studied in postmortem brains for more than 120 years and the resultant knowledge has not only helped us understand the etiology and pathogenesis of Alzheimer disease (AD), but has also pointed to possible modes of prevention and treatment. Within the last 15 years, it has become possible to image plaques in living subjects. This is arguably the single greatest advance in AD research since the identification of the Aβ peptide as the major plaque constituent. Read More

Pharmacogenetic studies in Alzheimer disease.

Neurologia (Engl Ed) 2022 May 1;37(4):287-303. Epub 2020 Jun 1.

Departamento de Sistemas Biológicos, Universidad Autónoma Metropolitana, Unidad Xochimilco, Coyoacán (México D.F.), Mexico. Electronic address:

Introduction: Alzheimer disease (AD) is the most common cause of dementia and is considered one of the main causes of disability and dependence affecting quality of life in elderly people and their families. Current pharmacological treatment includes acetylcholinesterase inhibitors (donepezil, galantamine, rivastigmine) and memantine; however, only one-third of patients respond to treatment. Genetic factors have been shown to play a role in this inter-individual variability in drug response. Read More

Erratum. Performance of the ESC 0/1-h and 0/3-h Algorithm for the Rapid Identification of Myocardial Infarction Without ST-Elevation in Patients With Diabetes. Diabetes Care 2020;43:460-467.

Diabetes Care 2022 May 20. Epub 2022 May 20.

During the conduction of a recent analysis, an error in the coding of the rule-in path of the ESC 0/3-h algorithm in the main database was discovered. This coding error affected the diagnostic measures for the positive predictive value and the specificity to detect acute myocardial infarction. In summary, the coding error resulted in an incorrect high relative increase of troponin comparing the baseline and 3-h value, while all other analyses were not affected. Read More
