Uterine leiomyomas (UL) are the most prevalent symptomatic human tumors at all and somatic mutations of the gene encoding mediator subcomplex 12 (MED12) constitute the most frequent driver mutations in UL. Recently, a rapid loss of mutated cells during in vitro growth of UL-derived cell cultures was reported, resulting in doubts about the benefits of UL-derived cell cultures. To evaluate if the...

Mutations in fumarate hydratase (FH) on chromosome 1q43 cause a rare cancer syndrome, hereditary leiomyomatosis and renal cell cancer (HLRCC), but are rare in nonsyndromic and common uterine leiomyoma (UL) or fibroids. Studies suggested that variants in FH or in a linked gene may also predispose to UL. We re-sequenced 2.3 Mb of DNA spanning FH in 96 UL cases and controls from the multiethnic NI...

A DNA-dependent in vitro transcription system for the human Ul small nuclear RNA (snRNA) promoter has been developed. This in vitro transcription system uses extracts of tissue culture cells to drive transcription of an RNA polymerase Il-transcribed snRNA gene. A Ul promoter (-393 to +192) template was constructed in which the sequences from +10 to +171 were replaced with a 179-bp sequence from...

Ultrasound is regarded a convenient and safe tool to acquire diagnostic information that we need for clinical use. For a long time ul trasound has been counted as a harmless method, but after all, there is a heating and a mechanical impact by ul trasound exposure. This influence can reveal both posi tive (e .g., cell plant growth) and negative (e.g. cell death) effects. Acoustic exposure patter...

Cerebellar Purkinje cells are excited by two afferent pathways: climbing and mossy fibers. Climbing fibers evoke large "complex spikes" (CSs) that discharge at low frequencies. Mossy fibers synapse on granule cells whose parallel fibers excite Purkinje cells and may contribute to the genesis of "simple spikes" (SSs). Both afferent systems convey vestibular information to folia 9c-10. After maki...

OBJECTIVE To assess the accuracy of PIMA Point-of-Care (POC) CD4 testing in rural Rakai, Uganda. METHODS 903 HIV positive persons attending field clinics provided a venous blood sample assessed on site using PIMA analyzers per manufacturer's specifications. The venous samples were then run on FACSCalibur flow cytometry at a central facility. The Bland-Altman method was used to estimate mean b...

Although absolute neutrophil counts (ANC) below 1.5x103/uL are used to define neutropenia as a marker of increased susceptibility to infections, their relationship with survival has not been examined. Since low counts trigger extensive investigations, determining prognostic cutoffs especially for different ethnicities and races is critical.A multiethnic cohort of 27,760 subjects, 65 years old a...

PURPOSE It is estimated that 50% to 75% of individuals who experience a stroke have persistent impairment of the affected upper limb (UL). There is a need to identify the best training strategies for retraining motor function of the UL. One intervention showing promise is virtual reality (VR), using either immersive or nonimmersive technology. Before recommending VR for use in clinical practice...

Inappropriate land use has caused a series of environmental disasters such as floods and sand storms, and some of them involved unused land changes with highly localized distributions in arid and semi-arid regions with fragile ecosystems. As the third-rank category of first-level land use/cover in China, unused land (UL) is now playing an increasingly important role in protection of the natural...
