Evaluation of maxillary buccal alveolar bone before and after orthodontic alignment without extractions: A cone beam computed tomographic study.

CONCLUSIONS: Nonextraction alignment with self-ligating brackets led to arch expansion associated with tipping of teeth. Expansion related to alignment resulted in horizontal and vertical bone loss at the incisors and mesiobuccal root of the first molars. Thinner BTs and more severe crowding before treatment increased the risk for buccal bone loss. PMID: 29911904 [PubMed - as supplied by publisher]

Srikanth, Rekha PuriaAbstractLong non coding RNAs (lncRNAs) have emerged as crucial players of several central cellular processes across eukaryotes. Target of Rapamycin (TOR) is a central regulator of myriad of fundamental cellular processes including amino acid transport under diverse environmental conditions. Here we investigated the role of lncRNA in TOR regulated amino acid uptake in S. cerevisiae. Transcription of lncRNA regulates local gene express...

Propagating neural waves in the cerebral cortex influence the integration of incoming sensory information with ongoing cortical activity. However, the neural circuit elements that support these cortical waves remain to be fully defined. Here, a novel tangential slice preparation was developed that exhibited propagating wave activity across the dorsal cortical sheet, as assessed using autofluorescence imaging following focal electrical stimulation. Analysis of functional connectivity in the slice preparation with laser-scanning photostimulation via glutamate uncaging revealed a lack of short-latency, presumed monosynaptic, ...

Back in March 2018, I co-authored (along with Scott King, the former editor ofDiabetes Health magazine) an article (catch the article athttps://www.diabeteshealth.com/good-bad-diabetes-advocacy-world/ for reference) about some patient advocacy wins and challenges ahead. One of the challenges ahead was about runaway insulin prices.We started to see action on runaway insulin prices in state capitals happen a few years ago.Nevada got an early start in 2017, introducing a transparency bill that requires drugmakers who made insulin specifically to report pricing, costs, and rebates. It was signed into law by the state's Republi...

AbstractIn this paper, a simple terahertz (THz) leaky-wave antenna (LWA) composed of periodic gapped graphene ribbons and a silicon substrate is presented. The graphene sheets of the antenna operate in an electric field with a resonance distribution of transverse electric (TE) surface plasmon polaritons (SPPs). The THz LWA has both negative and positive propagation constant with the variation of frequencies. Thus, the LWA performs as a composite right/left-handed (CRLH) LWA with backfire-to-endfire beam steering capability in the THz band. The working principle of the THz LWA is analyzed in detail using the theory of dispe...

ConclusionMulti-local alterations of spontaneous brain activity could form a network related to chronic pain, sensory discrimination, emotion and cognition, suggesting complicated central mechanisms of PHN. The combined-action of brain microstructure and function may play a critical role in comprehension of neurological mechanisms of PHN-induced pain.

Similar to many Termitidae, this species contains a mixed segment in the intestine, an anatomic distinct region composed of both mesenteric and proctodeal tissues. In Neocapritermes spp., a pair of intestinal protrusions referred to as mesenteric sacs are associated with the mixed segment. In the present study, with the aid of ...

The formation of the function groups of P(ANI/GMA) and P(ANI/GMA)-Ag2O nanocomposites have been investigated by FT-IR. The X-ray patterns of P(ANI/GMA)-Ag2O nanocomposites showed more than crystalline ...
