Pseudomyogenic hemangioendothelioma presenting as a penile lesion.

Pseudomyogenic hemangioendothelioma (PHE) is a rare, usually multifocal neoplasm typically affecting individuals in the second-to-fourth decade of life, with a male predominance. It often arises in the distal extremities and characteristically involves multiple tissue planes. Presentation of this neoplasm as a primary penile lesion is exceedingly rare, with only five cases previously documented in the literature.

P53 Overexpression May Represent an Early Marker of Clinicopathologic Progression in Vasculogenic Mesenchymal Lesions of Germ Cell Tumor Origin.

Vasculogenic mesenchymal lesions (VMLs) of germ cell tumor origin are thought to originate in postpubertal-type yolk sac tumor components and include a spectrum of lesions from teratoma with vasculogenic stroma (TVS), to low and high-grade vasculogenic mesenchymal tumors (VMTs). VMLs exhibit rudimentary to well-developed neoplastic vessels within primitive mesenchyme, being considered a neoplastic reiteration of embryonic vasculogenesis in the splanchnic mesoderm of the yolk sac. They occur in patients with primary mediastinal germ cell tumors after chemotherapy, and a subset progresses to "somatic-type" sarcomas [including angiosarcoma (AS)], with high-grade VMTs likely portending a higher risk.

Genomic characterization, in vitro, and preclinical evaluation of two microencapsulated lytic phages VB_ST_E15 and VB_ST_SPNIS2 against clinical multidrug-resistant Salmonella serovars.

Background: Salmonella infections continue to be one of the essential public health issues threatening millions of people. With the increasing occurrence of resistance against conventionally used antibiotics, the search for alternatives has become crucial. In this study, we aimed to isolate, characterize, and evaluate two lytic bacteriophages against clinically isolated multidrug-resistant (MDR) Salmonella serovars.

Metabolic Interplay in the Tumor Microenvironment: Implications for Immune Function and Anticancer Response.

Malignant tumors exhibit rapid growth and high metabolic rates, similar to embryonic stem cells, and depend on aerobic glycolysis, known as the "Warburg effect". This understanding has enabled the use of radiolabeled glucose analogs in tumor staging and therapeutic response assessment via PET scans. Traditional treatments like chemotherapy and radiotherapy target rapidly dividing cells, causing significant toxicity.

Serotyping and Antimicrobial Resistance Profile of Enteric Nontyphoidal Recovered from Febrile Neutropenic Patients and Poultry in Egypt.

A total of 300 human fecal samples were collected from febrile neutropenic patients suffering from severe gastroenteritis, followed by identification and serological characterization of recovered isolates. Fifty nontyphoidal (NTS) serovars were recovered. A total of serologically identified 50 NTS serovars recovered from poultry of the same geographical area and during the same period as well as one standard strain Poona were supplied by the Bacterial Bank of Animal Health Research Institute of Egypt.

Work-related Musculoskeletal Pain among Different Dental Specialists in United Arab Emirates.

Introduction: Dentists are at a very high risk of developing work-related musculoskeletal pain. The present study aimed at studying the prevalence of musculoskeletal pain among different dental specialists in the United Arab Emirates (UAE), and correlating the region of pain with the type of clinical work done by the specialists.

Materials And Methods: A sample of more than 100 dentists was chosen randomly from different emirates in UAE.
