Chemopreventive effect of Pistacia vera leaf extract against Mammary Carcinoma Induced by Dimethyl-Benz(a)anthracene in vivo and in vitro: potential role of antioxidant, antiinflammatory and immune mechanisms.

Zoology Department, Faculty of Science, Al-Azhar University, 71524 Assuit, Egypt.
This study aimed to define the antitumor effect of ethanolic extract of Pistacia vera leaves (PEE) toward breast cancer both in vitro and in vivo using dimethyl-benz(a)anthracene (DMBA)-induced breast tumor in adult female rats. PEE showed a potent antioxidant effect toward both DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radicals with IC values of 72.6 and 107.

Introduction: Chimeric Antigen Receptor T-cell (CAR-T) therapy has emerged as a promising treatment for hematological malignancies. However, its association with immune-related complications such as rheumatic complications, is not well defined.
Methods: We conducted a retrospective study to analyze rheumatic complications in 310 patients treated with CAR-T therapy at a single center from January 2020 to May 2024.
Comparative study of pulpal response following direct pulp capping using synthesized fluorapatite and hydroxyapatite nanoparticles.
BMC Oral Health
January 2025
Basic Dental Sciences Department, Faculty of Dentistry, Zarqa University, PO Box 2000, Zarqa, 13110, Jordan.
Objective: This study aimed to investigate and compare the histological response of rabbit dental pulp after direct pulp capping with 3 different materials: mineral trioxide aggregate (MTA), nanoparticles of fluorapatite (Nano-FA), and nanoparticles of hydroxyapatite (Nano-HA) after 4 and 6-week time intervals.
Material And Methods: A total of 72 upper and lower incisor teeth from 18 rabbits were randomly categorized into 3 groups)24 incisors from six rabbits each. MTA Group: teeth were capped with MTA.

Laboratory of Behavioral Neuroscience, National Institute on Aging, Intramural Research Program, Baltimore, MD, USA.
Background: While immune function is known to play a mechanistic role in Alzheimer's disease (AD), whether immune proteins in peripheral circulation influence the rate of amyloid-b (Aβ) progression remains unknown.
Method: Using the Baltimore Longitudinal Study of Aging (BLSA; n = 196; mean follow-up: 5 years/4 scans), we identified immune-related proteins in plasma (candidate proteins) related to rates of change in cortical Aβ levels, as measured by C-PiB PET. Along with identifying genetic variants that contributed to candidate protein associations, characterizing their relationships with tau-PET and changes in ADRD biomarkers (Aβ, NfL, GFAP, pTau-181), and assessing their expression patterns in human microglia, we leveraged data from the Atherosclerosis Risk in Communities (ARIC) study to determine if changes in candidate protein levels precede Ab = β onset (n = 272), and whether they predict 20-year dementia risk during mid-life (n = 11,596) and 8-year dementia risk during late-life (n = 4,288).

Alzheimers Dement
December 2024
Department of Zoology, University of Lucknow, Lucknow, India.
Background: Various investigations have elucidated the impact of diet and environmental toxins on the aging process. Melamine (Mel) is a widely recognized and infamous food adulterant with documented toxicity in various organs, including the brain. Nevertheless, there is currently a dearth of reports on the neurotoxic effects of Mel in aging neurons.
