Cyclical Abdominal Pain in an Adolescent Female: A Case Report of Agenesis of the Lower Vagina.

Congenital agenesis of the lower vagina is a rare disorder characterized by separation between the unaffected proximal vagina and the distal vagina by a band of fibrous tissue. The typical presentation is an early adolescent female with chronic, cyclic abdominal pain and primary amenorrhea. In this case report, we describe an adolescent who presented to the pediatric emergency department on 2 occasions with a chief complaint of lower abdominal pain.

Recombination can lead to spurious results in retroviral transduction with dually fluorescent reporter genes.

Fluorescent proteins are routinely employed as reporters in retroviral vectors. Here, we demonstrate that transduction with retroviral vectors carrying a tandem-dimer Tomato (TdTom) reporter produces two distinct fluorescent cell populations following template jumping due to a single nucleotide polymorphism between the first and second Tomato genes. Template jumping also occurs between repeated sequences in the Tomato and green fluorescent protein (GFP) genes.

CRM1-dependent trafficking of retroviral Gag proteins revisited.

We analyzed the nuclear trafficking ability of Gag proteins from six retroviral genera. Contrary to a previous report, human immunodeficiency virus type 1 (HIV-1) Gag showed no propensity to cycle through the nucleus. The only Gag protein that displayed CRM1-dependent nuclear cycling was that of Rous sarcoma virus (RSV).
