The current work attempted to examine the histological and immunohistochemical features of the pancreas in the southern white-breasted hedgehog (Erinaceus concolor). Five adult male individuals were used in this study. Utilizing hematoxylin and eosin as well as Masson's trichrome, staining was performed on paraffin sections of the pancreas. Immunof...

Sunbirds, as specialized nectarivores, have developed multiple lingual and oropharyngeal peculiarities imposed by this dietary specialization that particularly extract floral nectar. We have described the functional morphology of the tongues and palates of the shining sunbird, Cinnyris habessinicus, using gross anatomical, histological, and scannin...

Authors' Contribution AA Alm-Eldeen conceived and designed the study. EAA, ERE, AAA and AA Alm-Eldeen collected and analysed the data. AA Alm-Eldeen and AAA wrote the manuscript. Aging is a natural biological process that leads to deterioration in the liver structures and functions due to oxidative stress and the reduction in the oxidative damage's...

The current investigation gave a full ultrastructural and histological description of the oropharyngeal cavity of the rock‐pigeon Columba livia dakhlae. Our study carried on 10 heads of adult rock pigeons by gross, scanning, and light microscopic examination, in addition to the immunohistochemical analysis of the cytokeratin of the dorsal surface m...

We characterized the morphological and anatomical adaptations of the lingual microstructures of the Eurasian collared dove and discussed their implications for its dietary niche. We analyzed tongues of nine S. decaocto using histological, histochemical, stereomicroscopic, and scanning electron microscopic techniques. Our findings showed that the to...

The present study was aimed to investigate the hepatoprotective effects of date palm hydroalcoholic extract (DP)in diabetic rats using biochemical and histopathological approaches. Diabetes was induced by administration of 60 mg/kg of streptozotocin intraperitoneally. In this analysis 32 adult rats were randomly divided into four groups; group 1: n...

We describe the functional morphology of the digestive tract of the Eurasian collared dove, Streptopelia decaocto using anatomical, morphometric, histological, histochemical, and ultrastructure techniques, and relate our findings to the species' dietary niche. Our results revealed that the esophagus is displaced on both sides of the neck and has hi...

Background: Protein kinase R (PKR) can suppress various types of solid tumors by inducing cellular oxidative stress and apoptosis. Likewise, Slaidorside, a plant flavonoid, was shown to have anti-tumorigenesis in many solid tumors. Objective: This study evaluated anti-tumorigenesis of Salidorside in HT29 colorectal cancer and investigated if the...

The objective of our study was to explore the deleterious effects of diabetes on the visual functions of the retina and to address whether the administration of vitamin A and carrot root extract (CE) confer retinal protection in hyperglycemic rats via modulation of oxidative stress, biochemical alternations, and retinal neurotransmission. Fifty mal...

This study investigates if the anti-tumor effect of Pterostilbene in the SKOV3 ovarian cancer (OC) cell line involves inhibition of cell metabolism and tested in this effect involves modulating AMPK and Akt-induced regulation of mTORC1. Initially, SKOV3 cells were cultured in the humidified conditions in DMEM media for 24 h with or without increasi...

This study examined if the anti-tumorigenesis effect of Exendin-4 in HT29 and HCT116 colorectal cancer (CRC) involves modulation of SIRT1 and Akt/GSR3K/β-catenin/NF-κB axis. HT29 and HCT116 cells were treated either with increasing levels of Exendin-4 (0.0-200 µM) or with Exendin-4 (at its IC50) in the presence or absence of EX-527 (10 µM/a selecti...

Purpose: To evaluate the antioxidant and cytotoxic properties of Kojic acid (KOJIC ACID) from Aspergillus tamarii MM11 against HepG-2 cell line derived from human liver cancer.Methods: The crude extract of A. tamarii MM11 was dissolved in a mixture of CH2Cl2/MeOH (85:15) and separation was done using silica gel chromatography using gradient size ex...

Aging is a natural process that affects testicular functions via increasing the oxidative stress. Quercetin, a polyphenolic, that has antioxidant activity. Therefore, this study was performed to examine the possible role of quercetin in modulating aging-induced testicular damage. Samples from 30-months old rats' testis were examined before and afte...

The liver is the main organ involved in lipid metabolism process and it helps in drug detoxification. Insulin resistance is considered one of risk reasons which lead to several metabolic diseases. Currently, berberine (BER) occupies a huge challenge against multiple diseases with no toxic effect. The present work was aimed to identify, does BER‐chl...
