Knowledge regarding the prevalence of the hepatitis E virus (HEV) in the general population can indicate public health and personal hygiene practices in a community. HEV spreads through the fecal-oral route and contaminates drinking water through sewage. Moreover, poverty also contributes to its prevalence in developing countries, including Pakistan. A cross-sectional study was conducted on 650 blood samples taken from suspected patients of HEV in the Rawalpindi cantonment area (Pakistan) from April to November 2019 at the Department of Virology, Armed Forces Institute of Pathology (AFIP), Rawalpindi, Pakistan. Out of them, 444 (68.15%) were male and 206 (31.85%) were female; the detection of anti-HEV IgG antibodies was carried out using a commercial Anti-Hepatitis E virus antibody (IgG) ELISA Kit. The overall anti-HEV IgG prevalence percentages were 19.23% and 4.77% in males and females, respectively. Patients were categorized into eight groups with ages ranging between 1 and 90 years. HEV IgG seroprevalence was the highest in ages 31–40 (6.46%). The study concluded that males aged 40 or above were susceptible and infected with hepatitis E.

Medicinal plants are known for their diverse use in the traditional medicine of the Himalayan region of Pakistan. The present study is designed to investigate the anticancer and antimicrobial activities of Prunus cornuta and Quercus semicarpifolia. The anticancer activity was performed using cancerous human cell lines (HepG2, Caco-2, A549, MDA-MB-231, and NCI-H1437 carcinoma cells), while the antimicrobial activity was conducted with the agar-well diffusion method. Furthermore, toxicity studies were performed on alveolar and renal primary epithelial cells. Initially, different extracts were prepared by maceration techniques using n-hexane, chloroform, ethyl acetate, butanol, and methanol. The preliminary phytochemical screening showed the presence of secondary metabolites such as alkaloids, tannins, saponins, flavonoids, glycosides, and quinones. The chloroform extract of P. cornuta (PCC) exhibited significant inhibitory activity against Acinetobacter baumannii (16 mm) and Salmonella enterica (14.5 mm). The A. baumannii and S. enterica strains appeared highly susceptible to n-hexane extract of P. cornuta (PCN) with an antibacterial effect of 15 mm and 15.5 mm, respectively. The results also showed that the methanolic extracts of Quercus semecarpifolia (QSM) exhibited considerable antibacterial inhibitory activity in A. baumannii (18 mm), Escherichia coli (15 mm). The QSN and QSE extracts also showed good inhibition in A. baumannii with a 16 mm zone of inhibition. The Rhizopus oryzae strain has shown remarkable mycelial inhibition by PCM and QSN with 16 mm and 21 mm inhibition, respectively. Furthermore, the extracts of P. cornuta and Q. semicarpifolia exhibited prominent growth inhibition of breast (MDA-MB-231) and lung (A549) carcinoma cells with 19–30% and 22–39% cell viabilities, respectively. The gut cell line survival was also significantly inhibited by Q. semicarpifolia (24–34%). The findings of this study provide valuable information for the future development of new antibacterial and anticancer medicinal agents from P. cornuta and Q. semicarpifolia extracts.

Background: Plants have been considered a vital source of modern pharmaceutics since the paleolithic age. Contemporary chemotherapeutic drugs for cancer therapy are chemical entities sourced from plants. However, synthetic drugs or their derivatives come with severe to moderate side effects for human health. Hence, the quest to explore and discover plant-based novel anticancer drugs is ongoing. Anticancer activities are the primary method to estimate the potential and efficacy of an extract or compound for drug discovery. However, traditional in vitro anticancer activity assays often show poor efficacy due to the lack of in-vivo-like cellular environment. In comparison, the animal-based in vivo assays lack human genetic makeup and have ethical concerns. Aim: This study aimed to overcome the limitations of traditional cell-culture-based anticancer assays and find the most suitable assay for anticancer activity of plant extracts. We first reported utilizing a liver tumor microphysiological system in the anticancer effect assessment of plant extracts. Methodology: Methanolic extracts of Acer cappadocicum Gled were used to assess anticancer activity against liver tumor microphysiological system (MPS), and cell viability, liver function tests, and antioxidant enzyme activities were performed. Additionally, an embedded transepithelial electrical resistance sensor was utilized for the real-time monitoring of the liver tumor MPS. The results were also compared with the traditional cell culture model. Results: The study demonstrated the superiority of the TEER sensor-based liver tumor MPS by its better anticancer activity based on cell viability and biomarker analysis compared to the traditional in vitro cell culture model. The anticancer effects of the plant extracts were successfully observed in real time, and methanolic extracts of Acer cappadocicum Gled increased the alanine transaminase and aspartate aminotransferase secretion, which may reveal the different mechanisms of these extracts and suggest a clue for the future molecular study of the anticancer pathways. Conclusion: Our results show that the liver tumor microphysiological system could be a better platform for plant-based anticancer activity assessment than traditional cell culture models.
