Congenital ossicular chain anomalies are rare, but are clinically important because hearing loss in most cases is correctable by appropriate surgical interventions. The great diversity in anatomic variations makes congenital ossicular chain anomalies a surgical challenge for otologists. Theoretically, endoscopic surgery might be suitable for management of congenital ossicular chain anomalies by improving visualization of lesions and preserving uninvolved anatomic structures as compared to conventional microscopic surgery...

Testing how populations are locally adapted and predicting their response to their future environment is of key importance in view of climate change. Landscape genomics is a powerful approach to investigate genes and environmental factors involved in local adaptation. In a pooled amplicon sequencing approach of 94 genes in 71 populations, we tested if >3'500 single nucleotide polymorphisms (SNPs) in the three most common oak species in Switzerland (Quercus petraea, Q. pubescens, Q. robur) show an association with abiotic factors related to local topography, historical climate, and soil characteristics...

We performed whole-genome sequencing on an individual from a family with variable psychiatric phenotypes that had a sensory processing disorder, apraxia, and autism. The proband harbored a maternally inherited balanced translocation (46,XY,t(11;14)(p12;p12)mat) that disrupted LRRC4C, a member of the highly specialized netrin G family of axon guidance molecules. The proband also inherited a paternally derived chromosomal inversion that disrupted DPP6, a potassium channel interacting protein. Copy Number (CN) analysis in 14,077 cases with neurodevelopmental disorders and 8,960 control subjects revealed that 60% of cases with exonic deletions in LRRC4C had a second clinically recognizable syndrome associated with variable clinical phenotypes, including 16p11...

Highly conserved eukaryotic histones are polybasic proteins that package DNA into nucleosomes, a building block of chromatin, allowing extremely long DNA molecules to form compact and discrete chromosomes. The histone N-terminal tails that extend from the nucleosome core act as docking sites for many proteins through diverse posttranslational modifications, regulating various DNA transactions. In this report, we present evidence that the nucleosomes can positively regulate the enzymatic activity of Rad27 (yeast Fen1), a major processing enzyme important for Okazaki fragment in eukaryotes...

BACKGROUND: Periodontal disease is chronic inflammatory process that affects the attachment structures of the teeth and constitutes a significant cause of tooth loss in adults. Although different bacteria play an important role in the triggering of this condition, the progression and severity of the disease are strongly affected by the host immune response, which is under the control of different immune-regulatory mechanisms, including T regulatory (Treg) cells. The aim of this study was to assess the frequency and function of CD69(+) Treg lymphocytes in patients with chronic periodontal disease...

Type 1 copper (T1Cu) proteins are electron transfer (ET) proteins involved in many important biological processes. While the effects of changing primary and secondary coordination spheres in the T1Cu ET function have been extensively studied, no report has explored the effect of the overall protein structural perturbation on active site configuration or reduction potential of the protein, even though the protein scaffold has been proposed to play a critical role in enforcing the entatic or "rack-induced" state for ET functions...

The molecular mechanisms and genetic architecture that facilitate adaptive radiation of lineages remain elusive. Polymorphic chromosomal inversions, due to their recombination-reducing effect, are proposed instruments of ecotypic differentiation. Here we study an ecologically diversifying lineage of An. gambiae, known as the Bamako chromosomal form based on its unique complement of three chromosomal inversions, to explore the impact of these inversions on ecotypic differentiation. We used pooled and individual genome sequencing of Bamako, typical (non-Bamako) An...

BACKGROUND AND PURPOSE: Peptides from venomous animals have long been important tools for understanding pain mechanisms and for the discovery of pain treatments. Here, we hypothesized that Phα1β, a peptide purified from the armed spider Phoneutria nigriventer venom, produces analgesia by blocking the transient receptor potential ankyrin 1 (TRPA1) channel. EXPERIMENTAL APPROACH: Cultured rat dorsal root ganglion (DRG) neurons, human IMR90 fibroblasts or HEK293 cells expressing the human TRPA1 (hTRPA1-HEK293), TRPV1 (hTRPV1-HEK293) or TRPV4 (hTRPV4-HEK293), were used for calcium imaging and electrophysiology...

Previous human study suggested that fresh-frozen intervertebral disc allograft transplantation can relieve neurological symptoms and restore segmental kinematics. Before wide clinical application, research into the pathophysiology of the postoperative disc allograft is needed. One important question that remains to be answered in disc allografting is the healing process of the host-graft interface and the subsequent change of the endplates. With the goat model for lumbar disc allografting, histology, micro-computed tomography analysis, scanning electron microscopy and energy-dispersive X-ray spectroscopy mapping were applied to evaluate the healing of the host-graft interfaces, the remodelling of subchondral bone, and the changes of the bony and cartilaginous endplates after transplantation...

We read the report by Çeltikçi et al in the Turkish Neurosurgery with great interest. In this single-center retrospective study, they analysed 449 intracranial meningioma patients underwent open surgery. They stated that venous thromboembolism (VTE) had been seen in 21 (4.6%) of their patients. This is an important issue because VTE, including deep vein thrombosis (DVT) and pulmonary embolism (PE), is the most common overall complication in meningioma surgery and is fatal in up to one third of patients (2)...

Background: Surgical trauma triggers an important postoperative stress response characterized by significantly elevated levels of cytokines, an event that can favor the emergence of immune disorders which lead to disturbances in the patient's body defense. The magnitude of postoperative stress is related to the degree of surgical trauma. Aim: To evaluate the expression of pro-inflammatory (TNF-α, IFN-γ, IL-1β, and IL-17) and anti-inflammatory (IL-4) cytokines in patients submitted to conventional and single-port laparoscopic cholecystectomy before and 24 h after surgery...
