The Burden of Cancer, Government Strategic Policies, and Challenges in Pakistan: A Comprehensive Review.

Cancer is a severe condition characterized by uncontrolled cell division and increasing reported mortality and diagnostic cases. In 2040, an estimated 28.4 million cancer cases are expected to happen globally. In 2020, an estimated 19.3 million new cancer cases (18.1 million excluding non-melanoma skin cancer) had been diagnosed worldwide, with around 10.0 million cancer deaths. Breast cancer cases have increased by 2.26 million, lung cancer by 2.21 million, stomach by 1.089 million, liver by 0.96 million, and colon cancer by 1.93 million. Cancer is becoming more prevalent in Pakistan, with 19

The impact of vaping and smoking on nicotine intake and toxicant exposure among youth in England compared with youth in North America.

BACKGROUND: Youth vaping prevalence varies across countries and may be related to differing regulations/products. The emergence of cheap disposable vapes and high-concentration nicotine salts heightened concerns related to youth's ease of access, dependence and potential health risks. OBJECTIVES: We examined youth in England versus Canada and the United States and: how patterns of vaping/smoking varied, given the countries' different regulatory frameworks nicotine and potential toxicant exposure in youth who vape, smoke or do neither in youth who use salt and free-base nicotine respiratory sy

Construction of Salmonella typhimurium YG7108 strains, each coexpressing a form of human cytochrome P450 with NADPH-cytochrome P450 reductase.

A series of Salmonella typhimurium (S. typhimurium) YG7108 strains, each coexpressing a form of human cytochrome P450 (CYP) (CYP1A1, CYP1A2, CYP1B1, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP3A4, or CYP3A5) together with human NADPH-cytochrome P450 reductase (OR), was established. The parental S. typhimurium YG7108, derived from TA1535, lacks two O(6)-methylguanine-DNA methyltransferase genes, ada and ogt, and is highly sensitive to the mutagenicity of alkylating agents.

An Insight into Anticancer Effect of Propolis and Its Constituents: A Review of Molecular Mechanisms.

Propolis is a natural compound collected by honeybees from different parts of plants. Honeybees produce a sticky component besides honey by mixing the tree resin and other botanical sources with saliva called propolis or bee glue. Propolis was traditionally used as a wound healing substance, cosmetic, medicine, and many other conditions. Till now, there is no definite curable treatment for most cancers and chemotherapeutic drugs and drugs used for targeted therapies have serious side effects. According to a recent research, natural products are becoming increasingly essential in cancer prevent

Impact of e-cigarettes as cancer risk: A protocol for systematic review and meta-analysis.

BackgroundThe use of electronic cigarettes is one of the current public health problems on increasing alert, has been growing at an accelerating rate, and has become a public health emergency. Its importance is explained by the continuous growth and acceleration of oncological rates among all ages versus the absence of high-quality evidence, correlated to the use of nicotine derived products, being at their regular versions or the new ones. Available preclinical data indicate that activation of the sympathetic nervous system by nicotine inhaled from e-cigarettes may stimulate cancer developmen

The 'speck'-tacular oversight of the NLRP3-pyroptosis pathway on gastrointestinal inflammatory diseases and tumorigenesis.

The NLRP3 inflammasome is an intracellular sensor and an essential component of the innate immune system involved in danger recognition. An important hallmark of inflammasome activation is the formation of a single supramolecular punctum, known as a speck, per cell, which is the site where the pro-inflammatory cytokines IL-1β and IL-18 are converted into their bioactive form. Speck also provides the platform for gasdermin D protein activation, whose N-terminus domain perforates the plasma membrane, allowing the release of mature cytokines alongside with a highly inflammatory form of cell death

Atezolizumab alleviates the immunosuppression induced by PD‑L1‑positive neutrophils and improves the survival of mice during sepsis.

BACKGROUND: Until recently, tumors of the clivus and the anterior region of the posterior cranial fossa were considered extremely difficult to access and often inoperable using standard transcranial approaches. With the introduction into the neurosurgical practice of minimally invasive methods utilizing endoscopic techniques, it became possible to effectively remove hard-to-reach tumors, including central tumors of the anterior region of the posterior cranial fossa. METHODS: From 2008 to the present time, the inpatient institution has operated on 140 patients with various tumors of the base o

Unraveling the Anti-Cancer Mechanisms of Antibiotics: Current Insights, Controversies, and Future Perspectives.

Cancer persists as a significant global health challenge, claiming millions of lives annually despite remarkable strides in therapeutic innovation. Challenges such as drug resistance, toxicity, and suboptimal efficacy underscore the need for novel treatment paradigms. In this context, the repurposing of antibiotics as anti-cancer agents has emerged as an attractive prospect for investigation. Diverse classes of antibiotics have exhibited promising anti-cancer properties in both in vitro and in vivo studies. These mechanisms include the induction of apoptosis and cell cycle arrest, generation o

Candesartan cilexetil as a repurposed therapeutic candidate for nasopharyngeal carcinoma: Integrated in vitro and in silico analyses.

Nasopharyngeal carcinoma (NPC) is prevalent in East and Southeast Asia and is often diagnosed at advanced stages, where current treatment options are limited and associated with high relapse rates and toxicity. Repurposing clinically approved drugs provides a rapid, cost-effective strategy to identify new therapeutic interventions. Here, we investigated candesartan cilexetil (CC), an angiotensin II type 1 receptor (AT1R) blocker widely used for hypertension (13), for its potential anti-cancer effects in NPC. In vitro assays were performed to assess cell viability, proliferation, clonogenic sur

Reactive Oxygen Species Bridge the Gap between Chronic Inflammation and Tumor Development.

According to numerous animal studies, adverse environmental stimuli, including physical, chemical, and biological factors, can cause low-grade chronic inflammation and subsequent tumor development. Human epidemiological evidence has confirmed the close relationship between chronic inflammation and tumorigenesis. However, the mechanisms driving the development of persistent inflammation toward tumorigenesis remain unclear. In this study, we assess the potential role of reactive oxygen species (ROS) and associated mechanisms in modulating inflammation-induced tumorigenesis. Recent reports have e

A Review on the Multidisciplinary Approach for Cancer Management in the Eastern Mediterranean Region: A Focus on Nutritional, Lifestyle and Supportive Care.

Cancer is one of the leading causes of global morbidity and mortality and one of the most challenging global health conditions, impacting the lives of millions every year. The Eastern Mediterranean Region (EMR) is not on track to achieve the sustainable development goal (SDG) target 3.4 which aims to reduce premature mortality (i.e., before the age of 70 years) for non-communicable diseases (NCDs), including cancer, by a third by year 2030; instead, it is projected that the EMR will experience the least progress towards achieving this target. This review therefore highlights the importance of

Canine Gastric Cancer: Current Treatment Approaches.

Human gastric cancer (GC) ranks as the fifth most prevalent cancer worldwide, and is the third leading cause of cancer-related death. The incidence of GC is lower in dogs than in humans, accounting for less than 1% of all canine malignancies. In recent years, efforts have been made to understand the pathogenesis of GC and in find an appropriate therapy to maximize curative results, such as adjuvant chemotherapy treatments in addition to surgery. Although surgery is the first-line treatment, it is associated with several complications. In terms of chemotherapeutic intervention, canine gastric c
