Background: Associations between retinal venous occlusion (RVO), elevated intraocular pressure, and glaucoma have been reported. Further investigations into structural alterations in the fellow eyes of individuals with unilateral RVO have revealed that the peripapillary retinal nerve fiber layer is thinner than in healthy eyes, suggesting that there may be systemic risk factors common to both RVO and glaucoma. We aimed to evaluate changes in peripapillary retinal nerve fiber layer thickness (pRNFLT) among individuals with unilateral branch retinal vein occlusion (BRVO).

Identifying new hepatocellular carcinoma (HCC)-driven signaling molecules and discovering their molecular mechanisms are crucial for efficient and better outcomes. Recently, OMA1 and YME1L, the inner mitochondrial proteases, were displayed to be associated with tumor progression in various cancers; however, their role in HCC has not yet been studied. Therefore, we evaluated the possible role of OMA1/YME1L in HCC staging and discussed their potential role in cellular apoptosis and proliferation.

Article Synopsis
  • - In Egypt, pork production is mostly done on a small scale in backyards without proper sanitary measures, which can lead to exposure to harmful pathogens in pigs.
  • - A study conducted at Cairo's only licensed pig abattoir tested 332 serum samples and found a significant presence of food-borne zoonotic parasites, with specific seroreactivities noted for various parasites.
  • - The research revealed varying levels of seroprevalence based on location in Cairo and found that female pigs had a higher rate of certain antibodies compared to males, marking the first seroprevalence report for these parasites in Egyptian pigs.

Breast cancer, the most prevalent cancer among women, has posed a significant challenge in identifying biomarkers for early diagnosis and prognosis. This study aimed to elucidate the gene expression profile of Estrogen Receptor-1 (ESR-1), long non-coding RNA HOTAIR, and microRNA-130a in the serum of Egyptian breast cancer patients, evaluating the potential of HOTAIR and miR-130a as biomarkers for predicting pathological parameters in BC. The study involved 45 patients with primary BC, with serum samples collected preoperatively and postoperatively twice.

Currently, many challenges are associated with hepatocellular carcinoma (HCC) as the failure of early diagnosis, and the lack of effective therapy. This study aimed to investigate the possible role of tuftelin 1 (TUFT 1) in the early diagnosis of HCC and evaluate the potential contribution of the TUFT 1/Ca /phosphinositol 3 kinase (PI3K) pathway in dantrolene sodium (Dan) therapeutic outcomes. The study was performed on two sets of rats, the staging (30 rats) and treatment sets (80 rats).

Article Synopsis
  • The study investigates the prevalence of canine brucellosis in dogs in Egypt, noting the lack of previous documentation of infections in both dogs and humans in the country despite an increase in stray and imported dogs.
  • Researchers collected blood samples from 449 dogs and employed various testing methods, revealing that the true prevalence of the disease was higher in stray dogs (15%) compared to owned dogs (12.5%).
  • This study is significant as it marks the first discovery of brucellosis infections in dogs in Egypt and identifies the presence of specific species of bacteria through molecular techniques.

Trans-ferulic acid (TFA) is a polyphenolic compound present in many dietary supplements. The aim of this study was to get better chemotherapeutic outcomes through treatment protocols for human hepatocellular carcinoma (HCC). This study focused on the exploration of the in vitro influence of a combination of TFA with 5-fluorouracil (5-FU), doxorubicin (DOXO), and cisplatin (CIS) on HepG2 cell line.

Article Synopsis
  • * All strains were classified as ST16 with 43 virulence factors identified, and they were grouped into a complex type showing low diversity, suggesting a single introduction to the region.
  • * Comparison with 92 global B. suis genomes indicated the need for further investigation across different Egyptian areas to prevent the spread of the bacteria.

Background: Hepatocellular carcinoma (HCC) is a possible oncogenic progression during persistent hepatitis C-infection +/- type II diabetes mellitus (DM). We aim to investigate the plasma insulin, erythrocytic aldose reductase (AR) and sorbitol dehydrogenase (SDH) as possible predictive tools for HCC in hepatitis C-infected patients (HCV) +/- DM. Erythrocytes (RBCs) were adopted as a possible vehicle for pre-malignant variations being of short life span.

Brucellosis is one of the most common neglected zoonotic diseases globally, with a public health significance and a high economic loss in the livestock industry caused by the bacteria of the genus Brucella. In this study, 136 Egyptian Brucella melitensis strains isolated from animals and humans between 2001 and 2020 were analysed by examining the whole-core-genome single-nucleotide polymorphism (cgSNP) in comparison to the in silico multilocus variable number of tandem repeat analysis (MLVA-16). Almost all Egyptian isolates were belonging to the West Mediterranean clade, except two isolates from buffalo and camel were belonging to the American and East Mediterranean clades, respectively.

Prostate cancer, which is also known as prostatic adenocarcinoma, is an unconstrained growth of epithelial cells in the prostate and has become one of the leading causes of cancer-related death worldwide. The survival of patients with prostate cancer relies on detection at an early, treatable stage. In this paper, we introduce a new comprehensive framework to precisely differentiate between malignant and benign prostate cancer.

Aims: Hepatocellular carcinoma (HCC) is considered one of the main causes of cancer-related death globally. Combination therapy targeting different pathways can improve the efficacy of HCC management. Mitofusin 2 (Mfn2), a mitochondrial fusion protein, and a tissue inhibitor of matrix metalloproteinase 3 (Timp-3) were found to be downregulated in various cancers, including HCC.

Brucellosis, caused by the bacteria of the genus , is one of the most neglected common zoonotic diseases globally with a public health significance and a high economic loss among the livestock industry worldwide. Since little is known about the distribution of in Egypt, a total of 46 isolates recovered between 2012-2020, plus one animal isolate from 2006, were analyzed by examining the whole core genome single nucleotide polymorphism (cgSNP) in comparison to the in silico multilocus variable number of tandem repeat analysis (MLVA). Both cgSNP analysis and MLVA revealed three clusters and one isolate only was distantly related to the others.

Background: Hepatocellular carcinoma (HCC) is one of the most rapidly growing solid cancers, that is characterized by hypoxia. Hypoxia-inducible factor-1α (HIF-1α) is a transcription factor that regulates tumor proliferation and metastasis. It induces caveolin-1 (Cav-1) expression, a glycoprotein found on the membrane surface, then Cav-1 triggers angiogenesis and metastasis in HCC.
