Objective: To find out whether taking images of the male and female genitals during coitus is feasible and to find out whether former and current ideas about the anatomy during sexual intercourse and during female sexual arousal are based on assumptions or on facts.
Design: Observational study.
Setting: University hospital in the Netherlands.
Methods: Magnetic resonance imaging was used to study the female sexual response and the male and female genitals during coitus. Thirteen experiments were performed with eight couples and three single women.
Results: The images obtained showed that during intercourse in the "missionary position" the penis has the shape of a boomerang and 1/3 of its length consists of the root of the penis. During female sexual arousal without intercourse the uterus was raised and the anterior vaginal wall lengthened. The size of the uterus did not increase during sexual arousal.
Conclusion: Taking magnetic resonance images of the male and female genitals during coitus is feasible and contributes to understanding of anatomy.

The autoimmune disease systemic lupus erythematosus (SLE) is presented with many clinical symptoms. The transcription factor fork head box protein 3 (Foxp3) is expressed on regulatory T (T-reg) cells and essential for its development and function. Functional single-nucleotide polymorphisms (SNPs) in the Foxp3-3279 (rs3761548 C/A) gene influence SLE pathogenesis.

Multiple sclerosis (MS) is a disease of the central nervous system, characterized by progressive demyelination and inflammation. MS is characterized by immune system attacks on the myelin sheath surrounding nerve fibers. Genome-wide association studies revealed a polymorphism in the signal transducer and activator of transcription 4 (STAT4) gene that increases risk for MS.

Purpose: Attention-deficit/hyperactivity disorder (ADHD) increases the risk of road traffic injuries through various mechanisms including higher risky driving behaviors. Therefore, drivers with ADHD are shown to be more prone to road traffic injuries. This study was conducted in a community-based sample of drivers to determine how ADHD affects driving behavior components.

Purpose: To compare the effectiveness and safety of CT-guided iodine-125 seed brachytherapy in conjunction with chemotherapy against chemotherapy alone for the management of intermediate and advanced non-small cell lung cancer (NSCLC) lacking oncogenic driving genes.
Methods And Materials: Retrospective analysis was conducted on clinical data from 128 patients diagnosed with intermediate and advanced non-small cell lung cancer who received iodine-125 combined with chemotherapy or chemotherapy alone due to the absence of oncogenic driver gene mutations. The patients in two groups were compared at 6-month follow-up for objective remission rate (ORR), Disease control rate (DCR), local progression-free survival (LPFS), overall survival (OS), clinical symptom improvement, and adverse events.

Insecticide resistance in natural enemies can be used as a positive trait in integrated pest management programs by increasing the compatibility of two important tools; biological and chemical control. In this experiment, a field population of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) was selected with chlorantraniliprole for 35 generations (Chlor-Sel) developed a 100.32-fold resistance level compared to an unselected population (Unsel).
