Shotgun Lipidomics for Differential Diagnosis of HPV-Associated Cervix Transformation.

A dramatic increase in cervical diseases associated with human papillomaviruses (HPV) in women of reproductive age has been observed over the past decades. An accurate differential diagnosis of the severity of cervical intraepithelial neoplasia and the choice of the optimal treatment requires the search for effective biomarkers with high diagnostic and prognostic value. The objective of this study was to introduce a method for rapid shotgun lipidomics to differentiate stages of HPV-associated cervix epithelium transformation.

Vertical Transmission of SARS-CoV-2 in Second Trimester Associated with Severe Neonatal Pathology.

The effects of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection in women on the gestation course and the health of the fetus, particularly in the first and second trimesters, remain very poorly explored. This report describes a case in which the normal development of pregnancy was complicated immediately after the patient had experienced Coronavirus disease 2019 (COVID-19) at the 21st week of gestation. Specific conditions included critical blood flow in the fetal umbilical artery, fetal growth restriction (1st percentile), right ventricular hypertrophy, hydropericardium, echo-characteristics of hypoxic-ischemic brain injury (leukomalacia in periventricular area) and intraventricular hemorrhage at the 25th week of gestation.

Host gene expression profiling of cervical smear is eligible for cancer risk evaluation.

Aims: Uterine cervical carcinoma (CC) is known to be a delayed consequence of human papillomavirus (HPV) infection. Considering the reported influence of HPV on host genome activity, we conceived an approach to capture human gene expression profiles corresponding to increased risks of carcinogenesis.

Methods: A sample set of 143 female participants included a 'control' group of 23, a 'pathology' group of 83 (cervical abnormalities of varied grade including 10 cases of CC), and a 'HPV carrier' group of 37 (infected but manifesting normal cytology).

Protamine and fertilin mRNA: potential biomarkers of assisted reproductive technology outcomes.

We studied the relationship between the levels of protamines 1 and 2 (PRM1 and PRM2) and fertilin-β (ADAM-2) mRNA expression and outcomes of infertility treatment using assisted reproductive technologies was studied. Analysis of the relationships between the outcomes of in vitro fertilization and embryo transfer and profiles of the expression of seminal genes PRM1, PRM2, ADAM-2 mRNA, evaluated by reverse transcription quantitative PCR was carried out in 79 couples. Significant differences in the expression of seminal PRM1, PRM2, ADAM-2 mRNA were detected in couples with different outcomes of in vitro fertilization and embryo transfer.
