Tuco-tucos (Ctenomys) and related coruros (Spalacopus) are South American subterranean rodents. An energetically demanding lifestyle within the hypoxic/hypercapnic underground atmosphere may change the selective regime on genes involved in O2 transport in blood. In addition, some species of tuco-tucos may be found at high altitude, thus facing additional reductions in changes O2 availabily. We examined sequence variation in the alpha globin subunit gene of hemoglobine in these lineages, within a robust phylogenetic context...

The purpose of this study was to determine in a cadaver model, whether transfer of the posterior interosseous nerve (PIN) to the superficial branch of the ulnar nerve (SBUN) by a single approach was feasible. The experiment was carried out on five fresh cadavers. The ulnar nerve was split into its motor branches and the SBUN. The PIN was collected behind the interosseous membrane and sutured to the SBUN on its anterior surface. All sutures were tensionless and technically possible with the PIN's diameter being at least 50% of the SBUN's diameter in all cases...

Serotiny is an important adaptation for plants in fire-prone environments. However, different mechanisms also induce the opening of serotinous cones in the absence of fire in variably serotinous species. Xeriscence -cone opening driven by dry and hot conditions- is considered to be mediated only by the external environment, but endogenous factors could also play a significant role. Using the variably serotinous Pinus halepensis as our model species, we determined the effects of cone age and scales density in cone opening, and using in-situ and ex-situ manipulative experiments we investigated the role of water availability in the opening of serotinous cones...

Hematopoietic stem-cell transplantation (HSCT) is currently the only established curative treatment for sickle cell disease (SCD), but is limited by donor availability. Ethnicity is thought to have an impact on the complications experienced by patients that undergo HSCT and on the likelihood of identifying an HLA matched donor. In the present study, we investigated the genomic ancestry and the distribution of HLA allele groups in Brazilian patients with SCD, compared these HLA profiles to worldwide populations and evaluate the availability of HLA-matched donors...

Formation of secretary endometrial glands in the uterus known as adenogenesis is a typical process of branching morphogenesis involving dynamic epithelial growth and differentiation. Unsuccessful adenogenesis often leads to female infertility. However, it remains largely unexplored so far regarding the epigenetic machinery governing normal endometrial gland formation. Here, we demonstrated that PR-Set7, an epigenetic regulator for H4K20me1 modification, was extensively expressed in the postnatal uteri, and its conditional deletion resulted in a complete lack of endometrial glands and infertility in mice...

Carbon metabolism of Crabtree negative yeast Pichia pastoris was profiled using (13) C NMR to delineate regulation during exponential growth and to study the import of two precursors for branched-chain amino acid biosynthesis, α-ketoisovalerate and α-ketobutyrate. Cells were grown in aerobic batch cultures containing (i) only glucose, (ii) glucose along with the precursors, or (iii) glucose and Val. The study provided the following new insights. First, (13) C flux ratio analyses of central metabolism reveal an unexpectedly high anaplerotic supply of the tricarboxylic acid cycle for a Crabtree negative yeast, and show that a substantial fraction of glucose catabolism proceeds through the pentose phosphate pathway...

This work presents superconformal, bottom-up Au filling of high aspect ratio through silicon vias (TSVs) along with a predictive framework based on the coupling of suppression breakdown and surface topography. The work extends a previous study of superconformal Au deposition in lower aspect ratio TSVs. Deposition was performed in a Na3AuSO3 electrolyte containing a branched polyethyleneimine (PEI) deposition-rate suppressing additive. Voltammetric measurements using a rotating disk electrode (RDE) were used to assess the impact of the PEI suppressor concentration and transport on the rate of metal deposition, enabling the interplay between metal deposition and suppressor adsorption to be quantified...

BACKGROUND/PURPOSE: Trigeminocardiac reflex (TCR) is a unique clinical incident of acute change in hemodynamic balance, which may lead to hypotension, bradycardia, and even clinical crisis. Up to date, no study so far considers the impact of non-surgical root canal treatment (NSRCT) of irreversible pulpitis teeth under either local infiltration or block anesthesia on hemodynamic change possibly related to TCR. METHODS: This study enrolled 111 patients with 138 irreversible pulpitis teeth that were treated by two sessions of NSRCT...

Background In large-caliber pial macrofistulae (pMF), the combination of high blood flow velocity and large efferent artery diameter makes control over the endovascular vessel occlusion difficult and may result in the inadvertent venous passage of occlusive devices or embolic agents. Case descriptions Patient 1: A 27-year-old man presented with headache and ataxia. An infratentorial pMF supplied by both superior cerebellar arteries with venous ectasia was found. The first treatment attempt using balloons and coils failed since the position of either device could not be controlled because of a distal diameter of the feeding artery of 8 mm...

Vascular wilt caused by Verticillium dahliae is a destructive disease that represents a chronic economic problem on crop production worldwide. In this work we characterized two new regulators of pathogenicity in this species. Vph1 (VDAG_06555) was identified in a candidate gene approach as a putative homolog of the transcription factor Ste12. Vhb1 (VDAG_08786), identified in a forward genetics approach, is similar to the homeobox transcription factor Htf1, reported as a regulator of conidiogenesis in several fungi...
