Abstract Introduction Tucking is a common practice within the transwomen community. One study estimates that 70% of engage in this non-surgical gender affirming technique. It entails placement testes superiorly towards inguinal canal and penis inferiorly rectum to conceal male phenotype create female silhouette. By prolonged distortion normal anatomical lie testes, several genitourinary complic...

An embryo of an enantiornithine bird has been recovered from the Lower Cretaceous rocks of Liaoning, in northeast China. The bird has a nearly complete articulated skeleton with feather sheet impressions and is enclosed in egg-shaped confines. The tucking posture of the skeleton suggests that the embryo had attained the final stage of development. The presence of well-developed wing and tail fe...

Idealized laboratory experiments reported in the literature have been designed to simulate specific physical and chemical conditions. These laboratory conditions have allowed researchers to control the variables which affect the behavior of contaminants in the subsurface and to identify the mechanisms which are likely to occur in the field. An understanding of the various mechanisms of facilita...

Double aortic arch (DAA) is the most common congenital anomaly of the aortic arch system, in which the trachea and esophagus are completely encircled by connected segments of the aortic arch and its branches, often resulting in variable airway compression. We present a case of fetal DAA prenatally diagnosed by fetal echocardiography and clearly confirmed at autopsy. The autopsy visualization al...

During a study of 108 vacuum assisted deliveries, a fetal hand was detected in the pelvic space between the head and maternal sacrum in seven of the procedures. The larger presenting diameters resulting from the compound fetal presentations were reflected in a greater number of pulls and higher traction forces recorded during the deliveries. In all cases, extraction of the hand facilitated the ...
