Gestational trophoblastic neoplasm and women living with HIV and/or AIDS

open access: yesSouthern African Journal of HIV Medicine, 2015
The 2011 World Health Organization global report on HIV and/or AIDS estimated that sub-Saharan Africa comprised 67% of the global HIV burden, with a current estimate of 5.9 million cases in South Africa. Since the introduction of antiretroviral therapy, there has been an increase in the incidence of non-AIDS-defining cancers.

Immunophenotypic assessment of pure embryonal carcinoma and yolk sac tumour suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche

open access: yesHistopathology, Volume 89, Issue 2, Page 303-311, August 2026.
Immunohistochemical analysis of transcription factors in GCNIS associated with pure EC and YST suggests that reprogramming to non‐seminoma occurs outside the spermatogonial niche. In these tumors, reprogramming may occur immediately upon invasion of the stroma or within seminiferous tubules but outside the spermatogonial niche (i.e., in intratubular ...

Homonymous Quadrantanopsia as the First Manifestation of Cerebral Metastasis of Invasive Mole: a case report

open access: yesJournal of Medical Case Reports, 2012
Introduction Homonymous quadrantanopsia results from retrochiasmal lesions in the visual pathway. Invasive mole is a benign tumor that arises from myometrial invasion of a hydatidiform mole via direct extension through tissue or venous channels. Cerebral

Marked attenuation of P63 expression in plasmacytoid urothelial carcinoma with expanded immunohistochemical framework including E‐cadherin, P120, HER2 and TRPS1

open access: yesHistopathology, Volume 89, Issue 2, Page 338-346, August 2026.
Plasmacytoid urothelial carcinoma demonstrates marked attenuation of p63 expression together with frequent disruption of the E‐cadherin–p120 adhesion complex, supporting its characteristic discohesive growth pattern. Standardized HER2 scoring identifies a substantial positive subset, highlighting diagnostic pitfalls and potential therapeutic relevance ...

Clinicopathological and molecular characterization of HPV‐associated cervical poorly cohesive carcinoma: a rare aggressive entity

open access: yesThe Journal of Pathology: Clinical Research, Volume 12, Issue 4, July 2026.
Abstract Primary signet‐ring cell carcinoma and poorly differentiated adenocarcinoma with poorly cohesive morphology in the cervix are rare conditions, and their clinicopathological features remain poorly described. This study defines primary cervical poorly differentiated adenocarcinomas meeting the diagnostic criteria for poorly cohesive carcinoma as

A Biologically Dominant Trophoblastic Component Guiding Neoadjuvant EMA/CO in Endometrial Carcinoma: A Clinical Case Report

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Endometrial carcinoma with choriocarcinomatous components (ECCC) is a rare and aggressive malignancy for which optimal management remains undefined. We report a case illustrating how preoperative identification of a biologically dominant trophoblastic component can guide treatment sequencing and achieve durable remission.

A Case of a Chronic Ectopic Pregnancy in a Patient With Negative Serum β‐HCG

open access: yesClinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT Chronic ectopic pregnancy should be considered in women with adnexal masses and persistent abdominal pain, even when serum β‐hCG is negative, to prevent delayed diagnosis. This article reports a case of ectopic pregnancy with negative serum β‐hCG levels nearly 3 months after curettage.

Investigating the Role of Anti‐Leukemia Inhibitory Factor Antibody on Cytokine Profile in a Mouse Model of Breast Cancer

open access: yesCancer Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background Leukemia inhibitory factor (LIF), a member of the IL‐6 cytokine family, is increasingly recognized as a tumor‐promoting factor in breast cancer, where it contributes to immune suppression, tumor progression, and therapy resistance.

Research on the Mechanism of Natural Products Acting on Chronic Obstructive Pulmonary Disease

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
This figure illustrates that approximately 80 natural compounds exert therapeutic effects against chronic obstructive pulmonary disease by targeting pathological mechanisms such as airway inflammation, oxidative stress, airway remodeling, mucus hypersecretion, emphysema, protease–antiprotease imbalance, apoptosis, and autophagy.

Prevalence, Associated Factors, and Evaluation of Clinical and Biochemical Indices of Gestational Trophoblastic Tumors in Patients Referring to Imam Reza Hospital, Kermanshah: A Five‐Year Analytical Study (2017–2022)

open access: yesHealth Science Reports, Volume 9, Issue 7, July 2026.
ABSTRACT Background and Aims Gestational trophoblastic neoplasia (GTN) encompasses a spectrum of pregnancy‐related disorders and poses significant clinical challenges. Understanding its prevalence, clinical characteristics, and associated risk factors is essential for timely diagnosis and management.
