Altered Nasal Microbiota in Sinonasal Tumors: A Comparative Analysis of Malignant and Benign Sinonasal Tumors

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Although shifts in nasal microbiota have been well‐documented in inflammatory upper airway conditions, microbiota tumor‐associated alterations remain uncharacterized. This study is the first to compare sinonasal microbiota profiles of patients with malignant tumors (MT), benign tumors (BT), and controls, offering insights into tumor‐

Epidemiology and aetiology of cancer of the uterine cervix including the detection of carcinogenic N-nitrosamines in the human vaginal vault.

open access: yesSouth African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1975
Cancer of the uterine cervix occurs with high frequency in black females of several populations of Southern Africa. It accounts for 40-50% of all cancers in Black females in the Johannesburg area and for over 40% of those in women in the rural lowveld area of the Transvaal. The aetiology of this cancer has several distinct features, almost all of which

Modulation of DMBA- induced biochemical and histopathological changes by Syzygium cumini seed extract during skin carcinogenesis [PDF]

open access: yes, 2011
Aim & Method: The current study was designed to elucidate the protective effect of Syzygium cumini seed extract (SCE) on skin carcinogenesis induced by a single topical application of 7,12-dimethylbenz(a)anthracene (100 μg/100 μl of acetone) and 2 weeks ...

Transcriptomic validation of a 7,12 Dimethylbenz(a)anthracene (DMBA)‐induced leukemia rat model: Parallels with human leukemogenesis

open access: yesAnimal Models and Experimental Medicine, EarlyView.
7,12‐Dimethylbenz[a]anthracene (DMBA) could induce leukemia and other types of cancers in rat models. Transcriptomics revealed gene expression profile that parallels with human leukemia. DMBA‐induced differential gene expression could validate the developed rat model.

Cancer Chemoprevention by Traditional Chinese Herbal Medicine and Dietary Phytochemicals: Targeting Nrf2-Mediated Oxidative Stress/Anti-Inflammatory Responses, Epigenetics, and Cancer Stem Cells

open access: yesJournal of Traditional and Complementary Medicine, 2013
Excessive oxidative stress induced by reactive oxygen species (ROS), reactive nitrogen species (RNS), and reactive metabolites of carcinogens alters cellular homeostasis, leading to genetic/epigenetic changes, genomic instability, neoplastic ...

The Role of miRNAs in Chicken Immune Regulation and Prospects for Disease‐Resistant Breeding

open access: yesAnimal Research and One Health, EarlyView.
A schematic workflow illustrating the screening of disease‐resistant miRNAs and the generation of miRNA‐based disease‐resistant chickens via PGC‐mediated germline genome editing. ABSTRACT MicroRNAs (miRNAs) are emerging as pivotal regulators of the immune system, playing a decisive role in shaping disease resistance in chicken.

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and
