A new series of 4-nitroimidazole bearing aryl piperazines 7-16 , tetrazole 17 and 1,3,4-thiadiazole 18 derivatives was synthesized. All derivatives were screened for their anticancer activity against eight diverse human cancer cell lines (Capan-1, HCT-116, LN229, NCI-H460, DND-41, HL-60, K562, and Z138). Compound 17 proved the most potent compound of the series inhibiting proliferation of most of the selected human cancer cell lines with IC50 values in the low micromolar range. In addition, compound 11 exhibited IC50 values ranging 8...

Currently, the effect of miR-130 on non-small cell lung cancer (NSCLC) remains controversial. In this study, the expression of miR-130 and lncRNA MRPL39 in tumor and non-tumor tissues of NSCLC patients was examined using real-time PCR (RT-PCR) and correlated with the prognosis of NSCLC. The phenotypic effects of miR-130 and MRPL39 on proliferation and migration of NSCLC cell line A549 cells were assessed through CCK-8 and Transwell assays with miR-130 mimic and MRPL39 (mitochondrial ribosomal protein L39) overexpressed plasmid transfection...

INTRODUCTION: Breast cancer affects one in eight women during their lifetime; it may coincide with other diseases due to its high prevalence. Different pathologies that occur simultaneously with breast cancer, or later during its course, lead to multiple interactions with cancer and have a significant impact on its management. PRESENTATION OF CASE: A 58-year-old Syrian female was admitted to our hospital for compliant of abdominal distension. Following complete examination, obtained biopsies confirmed the diagnosis of peritoneal tuberculosis...

INTRODUCTION: The majority of lung cancers are caused by tobacco use, which is linked to lung tumors of all major histological types. A considerable fraction of lung cancer cases, the vast majority of which are adenocarcinomas, occur in "never smokers," who are characterized as having smoked fewer than 100 cigarettes in their lives. The primary objective was to assess risk factors for lung cancer in non-smokers. In contrast, secondary objectives included evaluating histological subtype, staging, and performance status and exploring associations between risk factors and common driver mutations...

Bacillus Calmette-Guérin (BCG) is an attenuated strain of Mycobacterium bovis . Although it was developed as a prophylactic vaccine against tuberculosis (TB), researchers have also evaluated it for preventing cancer development or progression. These studies were inspired by the available data regarding the protective effects of microbial infection against cancers and an inverse relationship between TB and cancer mortality. Initial studies demonstrated the efficacy of BCG in preventing leukemia, melanoma and a few other cancers...

UNLABELLED: Mycobacterium bovis BCG is the vaccine against tuberculosis and an immunotherapy for bladder cancer. When administered intravenously, BCG reprograms bone marrow hematopoietic stem and progenitor cells (HSPCs), leading to heterologous protection against infections. Whether HSPC-reprogramming contributes to the anti-tumor effects of BCG administered into the bladder is unknown. We demonstrate that BCG administered in the bladder in both mice and humans reprograms HSPCs to amplify myelopoiesis and functionally enhance myeloid cell antigen presentation pathways...

In April 1984, 40 years ago, the Secretary of the US Department of Health and Human Services announced that Dr. Robert Gallo and his colleagues at the National Cancer Institute (NCI) had confirmed the cause of acquired immunodeficiency syndrome (AIDS) as a retrovirus, which became known as human immunodeficiency virus (HIV) in 1986. For the past 40 years, prevention and cure of HIV infection have been the dual 'holy grail' sought but still not achieved. By the beginning of 2024, the World Health Organization (WHO) estimated that in the past 40 years, between 65...

AIM OF THE STUDY: Multiple ring-enhancing lesions are commonly experienced group of brain pathologies which we come across in day-to-day practice. Clinical symptoms in these lesions are quite non-specific, and hence, it is difficult to reach a final diagnosis. However, these lesions have a varied group of differential diagnosis and it is sometimes difficult to have an accurate diagnosis on conventional MRI. This article was written with the objective of discussing the demographical study and etiology, clinical diagnosis and management for these patients...

Stage III non-small cell lung cancer (NSCLC) exhibits significant diversity, making it challenging to define an optimal treatment. A collaborative multidisciplinary approach is essential in crafting individualized treatments. Previously, targeted therapies and immunotherapies were commonly used to treat patients with advanced and metastatic lung cancer. Such treatments are now being extended to individuals considered surgery, as well as patients once considered unsuitable for surgery. These changes have increased surgical success and substantially reduced postoperative recurrence...

Mycobacterium bovis Bacillus Calmette-Guérin (BCG) protects against childhood tuberculosis; and unlike most vaccines, BCG broadly impacts immunity to other pathogens and even some cancers. Early in the COVID-19 pandemic, epidemiological studies identified a protective association between BCG vaccination and outcomes of SARS-CoV-2, but the associations in later studies were inconsistent. We sought possible reasons and noticed the study populations often lived in the same country. Since individuals from the same regions can share common ancestors, we hypothesized that genetic background could influence associations between BCG and SARS-CoV-2...

Peritoneal tuberculosis (TB) is known to mimic advanced ovarian cancer. In this case report, we describe a unique case of ovarian cancer (endometrioid carcinoma grade 3) at the International Federation of Gynecology and Obstetrics (FIGO) stage IC1 with pulmonary and peritoneal TB, which was suspected preoperatively to be a coexistence of advanced ovarian cancer and pulmonary TB. A 68-year-old woman presented with a prominent abdominal mass and fever. Laboratory investigations, imaging, and sputum analysis indicated a probable diagnosis of ovarian cancer at FIGO stage IIIC, characterized by peritoneal dissemination and para-aortic lymph node metastasis, which was further complicated by coexisting pulmonary TB...

PURPOSE: Epidemiological TB data indicate differences in infection prevalence, progression rates, and clinical disease incidence between sexes. In contrast, evidence on sex-specific differential (post) TB case fatality in Europe has not been synthesized systematically. METHODS: We searched electronic databases and grey literature up to December 2020 for studies reporting sex-stratified TB death data for Europe. The JBI critical appraisal tools served for bias risk assessment and subgroup analyses for studying heterogeneity...

CONTEXT: The incidence of tuberculosis (TB) complicated by lung cancer has been increasing yearly worldwide. The overlapping effects of these two diseases leads to difficulties in clinical treatment and care. Single-care modalities fail to meet the clinical-care requirements of these complex diseases for both psychological and physical treatment. OBJECTIVE: The study intended to evaluate the clinical efficacy of integrated nursing plus a psychological intervention for patients with TB complicated by lung cancer...

INTRODUCTION: Tuberculosis is one of the infectious diseases with greater morbidity and mortality worldwide. Cancer causes an important immunosuppression with increased risk of infections. There is an enlarged bidirectional incidence between tuberculosis and cancer, mainly due to latent tuberculosis. GUIDELINES REVIEW: There is great discrepancy between recommendations for screening and prophylaxis of latent tuberculosis in patients with solid tumors and systemic cancer therapy among different medical societies and guidelines...

BACKGROUND AND OBJECTIVE: Immune checkpoint inhibitors (ICIs) have revolutionized oncologic treatment. Whether ICIs increase susceptibility to or provide protection against mycobacterial infections remains controversial. The objective of this narrative review is to summarize the literature on the link between ICI use and mycobacterial infections-tuberculosis and non-tuberculous mycobacterial (NTM) infections-and to critically discuss evidence linking ICIs with mycobacterial infections, the possible confounders, and, if indeed the ICIs predispose to such infections, the potential mechanisms of how this may occur...

ELISpot (enzyme-linked immunospot) is a powerful immunological tool for the detection of cytokine-secreting cells at a single-cell resolution. It is widely used for the diagnosis of various infectious diseases, e.g., tuberculosis and sarcoidosis, and it is also widely used in cancer immunotherapy research. Its ability to distinguish between active and latent forms of tuberculosis makes it an extremely powerful tool for epidemiological studies and contact tracing. In addition to that, it is a very useful tool for the research and development of cancer immunotherapies...

This case is about a 70-year-old man who presented with symptoms and laboratory reports that indicated differentials toward an infectious disease (pneumonia and tuberculosis). A lung mass was found in his chest X-ray and in the computerized tomography (CT) scan of his thorax. A biopsy was taken from the lung mass, and histopathological examination and immunohistochemical staining of the biopsy were done. The results revealed the presence of spindle cell carcinoma (SpCC) with vimentin and cytokeratin positivity...

Similar clinical features make the differential diagnosis difficult, particularly between lung cancer and pulmonary tuberculosis (TB), without pathological evidence for patients with concomitant TB infection. Our study aimed to build a nomogram to predict malignant pulmonary lesions applicable to clinical practice. We retrospectively analyzed clinical characteristics, imaging features, and laboratory indicators of TB infection patients diagnosed with lung cancer or active pulmonary TB at Xiangya Hospital of Central South University...

There is a compelling need to find drugs active against Mycobacterium tuberculosis ( Mtb ). 4'-Phosphopantetheinyl transferase (PptT) is an essential enzyme in Mtb that has attracted interest as a potential drug target. We optimized a PptT assay, used it to screen 422,740 compounds, and identified raltitrexed, an antineoplastic antimetabolite, as the most potent PptT inhibitor yet reported. While trying unsuccessfully to improve raltitrexed's ability to kill Mtb and remove its ability to kill human cells, we learned three lessons that may help others developing antibiotics...
