During a recent survey on digenean parasites infecting marine fish captured from water located along the Red Sea off Gizan Coasts, Saudi Arabia, thirty-two (29.09%) out of 110 fish were naturally infected with three different species of digenean parasites. The taxonomical status of the recovered worms was confirmed by light microscopy and molecular analysis. Transversotrema licinum infecting the Haffara seabream Rhabdosargus haffara possessed a transversely elongated body with eyespots and the anterior body margin with delineated velum along with its entire breadth. Oral sucker was absent, and eyespots were paired anterior to or at the level of ventral sucker. Phyllodistomum hoggettae from the urinary bladder of the Arabian Nagil Plectropomus areolatus was differentiated by its elongated body, narrow anterior end widened as going posteriorly with prominent marginal undulations in the hindbody. Gyliauchen volubilis infecting the marbled spinefoot Siganus rivulatus, was with fleshy body, conical, tapered anteriorly, convex dorsally, and concave ventrally. Prepharynx was very long and convoluted and had occupied the greater part of the anterior half of the body. Multiple sequence alignment and phylogeny were based on maximum likelihood analysis for the ITS–2 and 28S rDNA for Transversotrema licinum and Phyllodistomum hoggettae were constructed, respectively. They were compared to species within their families and further deposited into the Genebank under accession numbers MG 722711 and MG722710, respectively.

Prosopis juliflora (P. juliflora) is a widespread phreatophytic tree, which belongs to the Fabaceae family. The goal of the present study is to investigate the potential anti-cancer effect of P. juliflora leave extracts and to identify its chemical composition. For this purpose, MCF-7 (breast), HepG2 (liver), and LS-174T (colorectal) cancer cell lines were cultivated and incubated with various concentrations of P. juliflora leave extracts, and its impact on cell viability, proliferation, and cell cycle stages was investigated. P. juliflora leave extracts induced concentration-dependent cytotoxicity against all tested cancer cell lines. The calculated IC50 was 18.17, 33.1 and 41.9 μg/ml for MCF-7, HePG2 and LS-174T, respectively. Detailed analysis revealed that the cytotoxic action of P. juliflora extracts was mainly via necrosis but not apoptosis. Moreover, DNA content flow cytometry analysis showed cell-specific anti-proliferative action and cell cycle stages arrest. In order to identify the anti-cancer constituents of P. juliflora, the ethyl extracts were analyzed by liquid chromatography-mass spectrometry. The major constituents identified in the ethyl extracts of P. juliflora leaves were hydroxymethyl-pyridine, nicotinamide, adenine, and poly-(methyl methacrylate) (PMMA). In conclusion, P. juliflora ethyl acetate extracts have a potential anti-cancer effect against breast adenocarcinoma, hepatocellular carcinoma, and colorectal adenocarcinoma, and is enriched with anti-cancer constituents., EXCLI Journal;Vol. 19. 2020, pp.1282-1294

Osteoarthritis (OA) is one of the most prevalent conditions resulting to disability particularly in elderly population About 13% of women and 10% of men aged 60 years and older have symptomatic knee OA. The proportions of people affected with symptomatic knee OA is likely to increase due to the aging of the population and the rate of obesity or overweight in the general population. There are multiple factors associated with this progressive disease such as obesity, female gender, and repetitive trauma. Pain is the most common symptom in knee OA, a leading cause of chronic disability, clinical diagnosis will be supported by certain radiological findings. There are numerous conservative therapies that help to relive symptoms depend on severity of Osteoarthritis, and knee replacement remains standard of care in advance disease. Fat Micrografting is evolving technique with promising result in selected patients with regenerative and reparative effect of adipocyte-derived stem cell toward damaged cartilage and bone, which supported by clinical evidence.
