Glyphosate differentially affects the allergic immune response across generations in mice.

Exposure to environmental pollutants via food, particularly during the prenatal and early postnatal periods, has been linked to adverse effects on the immune system. Among these pollutants, the widely used pesticide glyphosate has been associated with endocrine disruption, autism, and cancer. Occupational high exposure to glyphosate has also been shown to influence immune function and exacerbate allergic asthma.

Expression of PIWIL3 in primary and metastatic melanoma.

Purpose: The PIWI-interacting RNA machinery in malignant melanoma (MM) has not been sufficiently studied. We aimed to investigate the PIWIL3 expression profiles in primary melanomas and metastases of MM including a correlation with clinical data.

Methods: We studied 161 primary melanomas, 45 lymph node metastases, and 16 distant metastases of 183 patients with MM.

Prognostic relevance of high atonal homolog-1 expression in Merkel cell carcinoma.

Background: It has recently been reported that atonal homolog 1 (ATOH1) gene is down-regulated in Merkel cell carcinoma (MCC) and thus may represent a tumor suppressor gene.

Objectives: We aimed to test for ATOH1 gene mutations and expression levels in MCC tissues and cell lines.

Methods: Genomic DNA isolation and amplification via PCR was successfully performed in 33 MCCs on formalin-fixed paraffin-embedded tissue and three MCC cell lines, followed by Sanger sequencing of the whole ATOH1 gene to detect genomic aberrations.

Subclavian artery rupture in a young man during excessive weight lifting.

We report a 19-year-old man with rupture of the right subclavian artery after an excessive exercise of weight lifting. Imaging showed a hematothorax and hematomediastinum, a pseudoaneurysm with a maximum diameter of 4 cm, and a dissection of the right vertebral artery. As an emergency procedure an interposition graft was performed for reconstruction of the right subclavian artery.

Hepatitis B Virus-Infected HepG2hNTCP Cells Serve as a Novel Immunological Tool To Analyze the Antiviral Efficacy of CD8+ T Cells In Vitro.

CD8(+) T cells are the main effector lymphocytes in the control of hepatitis B virus (HBV) infection. However, limitations of model systems, such as low infection rates, restrict mechanistic studies of HBV-specific CD8(+) T cells. Here, we established a novel immunological cell culture model based on HBV-infected HepG2(hNTCP) cells that endogenously processed viral antigens and presented them to HBV-specific CD8(+) T cells.
