Increased risk of graft-versus-host disease (GVHD) has been described in recipients of hematopoietic stem cell transplantations when the donor is a parous woman. Cells from prior pregnancies are now known to persist in women and could contribute to GVHD. We asked whether male DNA (presumed fetal microchimerism) is present in apheresis products of female donors. A total of 50 samples were studied by using real-time quantitative polymerase chain reaction (PCR) for the Y chromosome-specific sequence DYS14. Among 29 growth factor-mobilized peripheral blood mononuclear cell (G-PBMC) products, 34% were positive for male DNA. Quantitative results, expressed as DNA genome equivalent of male cells per million host cells (gEq/mil), ranged from 0 to 35 gEq/mil. Among 21 CD34-enriched cell fractions, 48% were positive with a range of 0 to 357 gEq/mil. In summary, male DNA was frequently detected in G-PBMC and CD34-enriched products from female donors. Whether fetal microchimerism contributes to GVHD merits further investigation.

Background: We report a rare case of fungal keratitis caused by , a filamentous fungus that is widely distributed in soil and graminaceous plants.
Case Presentation: A 40-year-old Mongoloid male patient came to our outpatient clinic with painful swelling of the left eye and redness, after being cut by a tree branch 1 week prior. After examination, the patient was diagnosed with a corneal ulcer of the left eye, and was given levofloxacin eye drops and levofloxacin ophthalmic gel.

Background: Carotid artery stenosis (CAS) may cause many cerebrovascular diseases, and a biomarker for screening and monitoring is needed. This study focused on the clinical significance of long-chain non-coding RNA (lncRNA) non-coding RNA activated by DNA damage (NORAD) in patients with CAS and aimed to search for potential biomarkers of CAS.
Methods: Eighty-six asymptomatic patients with CAS and 60 healthy individuals were enrolled, with corresponding clinical data and serum samples collected.

The genus Linton, 1910 comprises species which parasitize herbivorous kyphosid fish. In the present study, a new species is described based on fresh specimens collected from from Rio de Janeiro. The new species is characterized by having the oral sucker infundibuliform with 10 lobes, prepharynx two times longer than pharynx, presence of oesophagus, testes slightly lobed, round ovary and rectum with muscular sphincter connected to the anus.

Background: Neural tube defects (NTDs) are defined as an incomplete closure of the neural tube (NT), with a prevalence of 1.2 per 1000 live births around the world. Methylation of the maternally imprinted gene Insulin-like growth factor 2 (IGF2) is one of the epigenetic mechanisms that contribute significantly to the development of NTDs.

Recent genomic studies have allowed the subdivision of intracranial ependymomas into molecularly distinct groups with highly specific clinical features and outcomes. The majority of supratentorial ependymomas (ST-EPN) harbor ZFTA-RELA fusions which were designated, in general, as an intermediate risk tumor variant. However, molecular prognosticators within ST-EPN ZFTA-RELA have not been determined yet.
