- The almond and peach trees genomes shed light on the differences between these close speciesAn international team led by researchers has sequenced the genome of the almond tree and compared it to that of its closest relative, the peach tree. The most substantive differences between these species, so closely related in terms of evolution, are accounted for by the variation created by mobile genetic elements. The results provide some unique insights into the recent evolution of both species and will be key tools in their genetic improveme

- Exon Size and Sequence Conservation Improves Identification of Splice Altering Nucleotides [Article]Pre-mRNA splicing is regulated through multiple trans-acting splicing factors. These regulators interact with the pre-mRNA at intronic and exonic positions. Given that most exons are protein coding, the evolution of exons must be modulated by a combination of selective coding and splicing pressures. It has previously been demonstrated that selective splicing pressures are more easily deconvoluted when phylogenetic comparisons are made for exons o

Steinmetz, John H. FreemanABSTRACTIntracerebellar administration of cannabinoid agonists impairs cerebellum-dependent delay eyeblink conditioning (EBC) in rats. It is not known whether the cannabinoid-induced impairment in EBC is found with shorter interstimulus intervals (ISI), longer ISIs, or with trace EBC. Moreover, systemic administration

- Developing efficient and effective behavioral treatment for insomnia in cancer survivors: Results of a stepped care trialBackground Insomnia is common among cancer survivors. Although behavioral treatments for insomnia are effective, access is limited. Stepped care delivery models may provide insomnia treatment that is more efficient and accessible to cancer survivors. Methods Fifty‐one survivors (mean age, 55 years) with elevated Insomnia Severity Index (ISI) scores (≥12) first participated in Sleep Training Education Program (STEP)‐1: a single, sleep educa
- Decoding and encoding (de)mixed population responsesPublication date: October 2019Source: Current Opinion in Neurobiology, Volume 58Author(s): Sander W Keemink, Christian K MachensA central tenet of neuroscience is that the brain works through large populations of interacting neurons. With recent advances in recording techniques, the inner working of these populations has come into full view. Analyzing the resulting large-scale data sets is challenging because of the often complex and ‘mixed’ depe

- Comparisons of ISO depth of cure for a resin composite in stainless‐steel and natural‐tooth moldsThe purpose of this study was to compare the depth of cure (DOC) of a resin‐based composite (RBC) using the ISO DOC protocol with stainless‐steel and molar‐tooth molds (4 mm cylindrical cavity). The tooth mold included testing with and without the occlusal surface being covered with black tape around the cavity opening. The RBC was cured with either halogen (HAL) or light‐emitting diode (LED) light. The results showed that specimens made in the n
- Predicting primary stability of orthodontic mini‐implants, according to position, screw‐size, and bone quality, in the maxilla of aged patients: a cadaveric studyThis study aimed to evaluate the effect of implant size and bone condition on primary stability of orthodontic mini‐implants with a view to predict the primary stability before insertion. Four‐hundred and forty mini‐implants of two different diameters (2.0 and 2.3 mm) and lengths (7 and 12 mm) were inserted at 11 different positions in human cadaver maxillae. Before placement of mini‐implants, cone beam computed tomography (CBCT) scans were perfo

- Active Surveillance of Papillary Thyroid Microcarcinoma: Where Do We Stand?The recent sharp increase in thyroid cancer incidence is mainly due to increased detection of small papillary thyroid microcarcinoma (PTMC). Due to the indolent nature of the disease, active surveillance (AS) of low-risk PTMCs is suggested as an alternative to immediate surgery to reduce morbidity from surgery. For appropriately selected PTMC patients, AS can be a good management option and surgical intervention can be safely delayed until progre
