Item PI3K/AKT/mTOR Pathway in Breast Cancer Pathogenesis and Therapy: Insights into Phytochemical-Based Therapeutics(Nutrition and Cancer, 2025) Wali, Adil Farooq; Talath, Siajunisa; El Tanani, Mohamed; Rangraze, Imran Rashid; Babiker, Rasha; Shafi, Sadat; Bansal, RubyBreast cancer (BC) is listed as the most prevalent cancer form in women worldwide, with major subtypes classified by hormone receptor (HR) and HER2 status including, HR+/HER2– (~65–70%), HER2+ (~15–20%), Triple-Negative-HR–/HER2– (~10–15%) and rare sybtypes (<5%). Scientific evidence has revealed that PI3K/AKT/mTOR signaling cascade plays an important role in the development and progression of BC, contributing to key cellular processes including cell growth, proliferation, angiogenesis, and metastasis. Dysregulation of the components of this cascade including functional loss of Phosphatase and TENsin homolog (PTEN), PI3K hyperactivation, and gain-of-function of AKT, are frequently observed in BC subtypes, making it a promising target for therapeutic intervention. A myriad of studies have documented the potential of phytochemicals, including curcumin, chrysin, fisetin, genistein, resveratrol and lycopene as modulators of the PI3K/AKT/mTOR axis. These phytochemicals exhibit multifaceted mechanisms of action, including inhibition of key kinases, induction of apoptosis, suppression of angiogenesis, and reversal of resistance to chemotherapy. This review aims to provide a detailed overview about the role of PI3K/AKT/mTOR alteration in BC development and the current research on phytochemicals that modulate the PI3K/AKT/mTOR pathway in BC. We documented the molecular mechanisms through which these compounds exert their effects, their potential synergistic interactions with conventional therapies, and the challenges and prospects for their clinical application. The evidence presented underscores the promise of phytochemicals as novel, less toxic adjuncts to traditional BC therapies, warranting further exploration and development for clinical useItem Effect of Gum Arabic (Acacia Senegal) supplementation on visceral adiposity index (VAI) and blood pressure in patients with type 2 diabetes mellitus as indicators of cardiovascular disease (CVD): a randomized and placebo-controlled clinical trial(Lipids in Health and Disease, 2018) Babiker, Rasha; Elmusharaf, Khalifa; Keogh, Michael B.; Saeed, Amal M.Background: There is a strong association between cardiometabolic risk and adipose tissue dysfunction with great consequences on type 2 diabetic patients. Visceral Adiposity Index (VAI) is an indirect clinical marker of adipose tissue dysfunction. Gum Arabic (GA) is a safe dietary fiber, an exudate of Acacia Senegal. Gum Arabic had shown lipid lowering effect in both humans and animals. The aim of this trial was to determine the effect of GA supplementation on anthropometric obesity marker, Visceral Adiposity Index (VAI) and blood pressure in patients with type 2 diabetes mellitus. Methods: This randomized, double blinded, placebo controlled trial recruited a total of 91 type 2 diabetic patients (73 females, 18 males), age (mean ±SD) 50.09±9.3 years on hypoglycemic agents and were randomly assigned into two groups, either to consume 30 g of GA or 5 g of placebo daily for 3 months. Anthropometric obesity markers were measured and indices were calculated. Blood pressure was measured and high density lipoprotein (HDL) and triglycerides (TG) were determined in fasting blood samples at the start and end of the study period. Results: After intervention, Gum Arabic decreased BMI and VAI significantly (P < 0.05) in GA group by 2 and 23.7% respectively. Body adiposity index significantly decreased by 3.9% in GA group while there were no significant changes in waist circumference or waist-to-hip ratio (WHR). Systolic blood pressure significantly decreased by 7.6% in GA group and by 2.7% in placebo group from baseline with no significant changes in diastolic blood pressure in the two groups. Conclusion: Gum Arabic consumption at a dose of 30 g/d for 3 months may play an effective role in preventing weight gain and modulating adipose tissue dysfunction in type 2 diabetic patients, although no effect has been shown in waist-to-hip ratioItem Unraveling the tumor microenvironment: Insights into cancer metastasis and therapeutic strategies(Cancer Letters, 2024) El-Tanani, Mohamed; Rabbani , Syed Arman; Babiker, Rasha; Rangraze, Imran; Kapre, Sumedha; Palakurthi, Sushesh Srivastsa; Alnuqaydan, Abdullah M.; Aljabali, Alaa A.; Rizzo, Manfredi; El-Tanani, Yahia; Tambuwala, Murtaza M.This comprehensive review delves into the pivotal role of the tumor microenvironment (TME) in cancer metastasis and therapeutic response, offering fresh insights into the intricate interplay between cancer cells and their surrounding milieu. The TME, a dynamic ecosystem comprising diverse cellular and acellular elements, not only fosters tumor progression but also profoundly affects the efficacy of conventional and emerging cancer therapies. Through nuanced exploration, this review illuminates the multifaceted nature of the TME, elucidating its capacity to engender drug resistance via mechanisms such as hypoxia, immune evasion, and the establishment of physical barriers to drug delivery. Moreover, it investigates innovative therapeutic approaches aimed at targeting the TME, including stromal reprogramming, immune microenvironment modulation, extracellular matrix (ECM)-targeting agents, and personalized medicine strategies, highlighting their po tential to augment treatment outcomes. Furthermore, this review critically evaluates the challenges posed by the complexity and heterogeneity of the TME, which contribute to variable therapeutic responses and potentially unintended consequences. This underscores the need to identify robust biomarkers and advance predictive models to anticipate treatment outcomes, as well as advocate for combination therapies that address multiple facets of the TME. Finally, the review emphasizes the necessity of an interdisciplinary approach and the integration of cutting-edge technologies to unravel the intricacies of the TME, thereby facilitating the development of more effective, adaptable, and personalized cancer treatments. By providing critical insights into the current state of TME research and its implications for the future of oncology, this review highlights the dynamic and evolving landscape of this field.Item Neurological Manifestation among Patients with Visceral Leishmaniasis at the Tropical Teaching Hospital – Khartoum(Zagazig University Medical Journal, 2023) Ebrahim, Ahmed Alameleman Edris; Saeed, Mohammed Khalfallah; Nail, Abdelsalam; Abdelmalik, Rawan Iz Eldin Mohamed; Mohammed, Eltayeb Abdalla; Ahmed, Sali Elhaj; Ahmed, Ahmed Abdelaziz; Babiker, Rasha; Ali, Ibrahim ABackground: Leishmaniasis is an endemic disease in Sudan that caused by Leishmania spp. Several studies suggest neurological manifestations in visceral leishmaniasis, such as burning sensation, and weakness.

The caspase activation and the response of inflammation are governed by inflammasomes, which are sensors and transmitters of the innate immune system. They have always been linked to swelling and pain. Research has mainly concentrated on the NOD‑like protein transmitter 3 (NLRP3) inflammasome. Interleukin (IL)‑1 and IL‑18 are pro‑inflammatory cytokines that are activated by the NOD‑like antibody protein receptor 3 (NLRP3), which controls innate immune responses. The NLRP3 inflammasome has been associated with gum disease and other autoimmune inflammatory diseases in several studies. Scientists’ discovery of IL‑1’s central role in the pathophysiology of numerous autoimmune disorders has increased public awareness of these conditions. The first disease to be connected with aberrant inflammasome activation was the autoinflammatory cryopyrin‑associated periodic syndrome (CAPS). Targeted therapeutics against IL‑1 have been delayed in development because their underlying reasons are poorly understood. The NLRP3 inflammasome has recently been related to higher production and activation in periodontitis. Multiple periodontal cell types are controlled by the NLRP3 inflammasome. To promote osteoclast genesis, the NLRP3 inflammasome either increases receptor‑activator of nuclear factor kappa beta ligand (RANKL) synthesis or decreases osteoclast‑promoting gene (OPG) levels. By boosting cytokines that promote inflammation in the periodontal ligament fibroblasts and triggering apoptosis in osteoblasts, the NLRP3 inflammasome regulates immune cell activity. These findings support further investigation into the NLRP3 inflammasome as a therapeutic target for the medical treatment of periodontitis. This article provides a short overview of the NLRP3 inflammatory proteins and discusses their role in the onset of autoinflammatory disorders (AIDs) and periodontitis.Item Natural Bioactive Compounds in the Management of Periodontal Diseases: A Comprehensive Review(Molecules, 2024) Hashim, Nada Tawfig; Babiker, Rasha; Rahman, MuhammedMustahsen; Mohamed, Riham; Priya , Sivan Padma; Chaitanya, Nallan CSK; Islam, Md Sofiqul; Gobara, BakriPeriodontal diseases, chronic inflammatory conditions affecting oral health, are primarily driven by microbial plaque biofilm and the body’s inflammatory response, leading to tissue damage and potential tooth loss. These diseases have significant physical, psychological, social, and economic impacts, necessitating effective management strategies that include early diagnosis, comprehensive treatment, and innovative therapeutic approaches. Recent advancements in biomanufacturing have facilitated the development of natural bioactive compounds, such as polyphenols, terpenoids, alka loids, saponins, and peptides, which exhibit antimicrobial, anti-inflammatory, and tissue regenerative properties. This review explores the biomanufacturing processes—microbial fermentation, plant cell cultures, and enzymatic synthesis—and their roles in producing these bioactive compounds for managing periodontal diseases. The integration of these natural compounds into periodontal therapy offers promising alternatives to traditional treatments, potentially overcoming issues like antibiotic resistance and the disruption of the natural microbiota, thereby improving patient outcomes.Item Comparative Efficacy of Immune Checkpoint Inhibitors and Therapeutic Vaccines in Solid Tumors: A Systematic Review and Meta-Analysis of Randomized Controlled Trials(Vaccines, 2025) Babiker, Rasha; Wali, Adil Farooq; El-Tanani, Mohamed; Rabbani, Syed Arman; Rangraze, Imran; Satyam, Shakta Mani; Patni, Mohamed Anas; El-Tanani, YahiaBackground: Immune checkpoint inhibitors (ICIs) and therapeutic vaccines have emerged as promising immunotherapeutic strategies for solid tumors. However, their comparative efficacy in improving overall survival (OS) remains unclear. This systematic review and meta-analysis aimed to evaluate the efficacy of ICIs and therapeutic vaccines in improving OS in patients with solid tumors. Methods: A comprehensive search was con ducted across PubMed, Cochrane Library, Embase, and Clinical Trials.gov for randomized controlled trials (RCTs) published between 1 January 2010 and 31 December 2024. Studies comparing ICIs or therapeutic vaccines against control treatments (placebo, standard of care, or active comparators) in adults with solid tumors were included. The primary out come was OS, and data were pooled using RevMan (web). Risk of bias was assessed using the Cochrane Risk of Bias tool. Results: Thirteen RCTs involving 10,991 participants were included. A total of 5722 of them were treated with therapeutic vaccines or checkpoint inhibitors. Therapeutic vaccines demonstrated insignificant improvement in OS, with a pooled mean difference of 1.89 months (95% CI: −0.54–4.31; P = 0.13), although with homo geneity (I2 = 0%). ICIs showed a statistically significant OS benefit, with a pooled mean difference of 1.32 months (95% CI: 0.62–2.02; P = 0.0002) and low heterogeneity (I2 = 12%). Conclusions: Therapeutic vaccines provide a larger but less consistent benefit, whereas ICIs offer modest but more consistent survival advantage. These findings support the need for personalized immunotherapy approaches as well as further research to identify predictive biomarkers and optimize treatment strategies by acquiring deep insights into the TMEdynamic and behaviors.Item Possible role of inflammasomes in the pathogenesis of periodontal diseases(Preprints, 2023) Hashim, Nada; Babiker, Rasha; Mohammed, Riham; Gismalla, Bakri; Rehman, Mohammed MustahsenDr. Jurg Tschopp created the word "inflammasome" in 2002. Inflammasome activation and its function in disease processes have been the subject of significant investigation over the last 15 years. Four important inflammasomes have been identified: NLRP1, NLRP3, NLRC4, and AIM2. When these inflammasomes are activated, they process and secrete inflammatory cytokines such as IL-1b and IL-18, as well as cause pyroptosis, an inflammatory form of cell death. In this review, we will look at how these inflammasomes have been connected to Periodontitis pathogenesis.Item Metformin: A Dual-Role Player in Cancer Treatment and Prevention: A Comprehensive Systematic Review and Meta-Analysis(Medicina, 2025) Rangraze, Imran; Wali, Adil Farooq; El-Tanani , Mohamed; Patni , Mohamed Anas; Rabbani, Syed Arman; Babiker, Rasha; Satyam, Shakta Mani; El-Tanani, Yahia; Rizzo, ManfrediBackground and Objectives: Metformin is said to reduce the incidences and deaths resulting from cancer in patients suffering from type 2 diabetes mellitus, but the results have been inconsistent. Perform a systematic review and meta-analysis concentrating on the different outcomes of several cancers while taking into account the impact of metformin use. Materials and Methods: As of 15 October 2024, the literature for Medline, Embase, and WebofScience was systematically searched. ROBINS-I and the RoB 2 tool were used for assessing the risk of bias in observational studies and randomized controlled trials (RCTs), respectively. The strength of the evidence with respect to the GRADE criteria was checked. Random effects meta-analyses were conducted alongside sensitivity analyses, subgroup analyses, and meta-regressions. By utilizing funnel plots as well as Egger’s test and trim-and-fill analysis, publication bias was evaluated. Results: In total, 65 studies were included in the final analyses: Metformin intake was linked to a lower risk of cancer (RR 0.72; 95% CI: 0.64–0.81, I2 = 45%). Significant reductions were observed in breast cancer (RR 0.68; 95% CI: 0.55–0.83) and colorectal cancers (RR 0.62; 95% CI: 0.51–0.76). Evidence certainty fluctuated from moderate to low, though analyses confirmed the results. Plofs funded the publication bias, but adjustment in trim-and-fill did not change the outcome significantly. Conclusions: Metformin intake seems to lower the chances of developing several types of cancers, especially breast and colorectal cancers, but the observational designs hinder determining the causal factors for observational studies. There is a need for large RCTsItem Unveiling the perceptions of medical and allied health students towards cadaveric dissection and virtual resources in anatomy education: a cross sectional study(BMC Medical Education, 2025) Elbeshbeishy, Rana; Salama, Rasha; Goud, BK Manjunatha; Babiker, Rasha; Jhancy, Malay; Hamed, Nour; Oraby, Farah; Merghani, TarigBackground Cadaveric dissection has long been a cornerstone of anatomy education, offering unparalleled hands-on experience that fosters both intellectual and emotional growth in medical students. It plays a crucial role in shaping professional identity while enhancing anatomical understanding. However, the emergence of digital platforms, including virtual reality (VR), augmented reality (AR), and 3D modeling, presents new opportunities to transform anatomy education. Objectives This study explores the perceptions of medical and health sciences students at Ras Al Khaimah Medical and Health Sciences University (RAKMHSU) regarding the integration of digital tools alongside traditional cadaveric dissection. By comparing attitudes toward these approaches, the study aims to identify strategies like using 3D models, animations, and interactive apps to familiarize students with anatomical structures before entering the dissection lab for harmonizing traditional and digital learning methods to optimize anatomy education. Methods This cross-sectional study was conducted over seven months using an anonymous, structured 20-item questionnaire administered to 454 students from various health disciplines at Ras Al Khaimah Medical and Health Sciences University. A convenience sampling method was used. The questionnaire assessed sociodemographic data, attitudes toward cadaveric dissection, its significance in practical learning, comparisons with digital resources, and its role in professional development. Institutional approval was obtained, and informed written consent was secured from all participants before the study commenced. Results Medical students expressed significantly stronger support for cadaveric dissection compared to allied health students, particularly regarding emotional engagement (p < 0.05), perceived educational value (p < 0.001), and comfort with handling cadavers (p < 0.001). While both groups acknowledged the benefits of digital resources, medical students reported greater improvements in visualization, confidence, and interactive learning (p < 0.01). Conclusion Cadaveric dissection remains an essential pillar of anatomy education, offering irreplaceable benefits in anatomical comprehension and psychomotor skill development. This study highlights its role in fostering professional attributes while demonstrating that digital platforms serve as valuable complementary tools. Rather than replacing cadaveric dissection, these digital innovations enhance learning by creating a synergistic educational environment.
