REVIEW
Meis Moukayed, William B Grant
Global cancer incidence and mortality rates are high and increasing. Thus, it is imperative to find novel solutions to preventing cancer incidence and treating it at an affordable yet efficacious manner. The solar UVB-vitamin D-cancer hypothesis was first proposed in 1980 based on a geographical ecological study. Since then, numerous ecological and observational studies as well as studies of mechanisms have provided support for the hypothesis. However, observational studies have not provided consistent support, in part due to using a single blood draw from any season to use for serum 25-hydroxyvitamin D [25(OH)D] concentration in prospective studies with long follow-up times...

BACKGROUND: Fingertip amputations can be debilitating and challenging to treat, due to the need for both function and cosmesis. We studied the functional outcomes of patients receiving an antegrade homodigital neurovascular island flap for fingertip amputations. METHODS: From 2004 to 2013, we performed 13 cases of antegrade homodigital neurovascular island flaps. Functional outcomes were studied. Four had Allen Zone II and nine had Zone III injuries. Seven were performed as secondary surgery...

Vacuum-assisted closure (VAC) therapy is a sophisticated system that maintains a closed, humid, sterile and isolated environment. Wound infection is considered a relative contraindication. The objective of this study is to extend the indications for VAC therapy to include infected wounds by demonstrating its ability to increase the antibiotic concentration in the damaged and infected tissues. Patients who presented with ulcers infected with daptomycin-sensitive bacteria were eligible to be enrolled in this prospective study...

Border and Keller argue that candidate gene approaches are outdated and out-of-touch with the current understanding of the genetic architecture of complex behavioral traits and should be abandoned in favor of unbiased, genome-wide approaches. Border and Keller further suggest that a candidate gene should not be selected for in-depth investigation unless identified by a well-powered genome-wide association study (GWAS). An alternative perspective is offered that candidate approaches can be sensible for developmental and deep-phenotyping studies aimed at elucidating particular biological pathways responsible for the emergence of psychological phenotypes, and that candidates should not necessarily be expected to be confirmed by, or solely selected based on, GWAS...

A revascularization procedure was shown to be the best alternative therapy for immature teeth with necrotic pulp and apical infection. A 12 year old female with a history of trauma to her upper central incisor and a sinus tract was referred for endodontic treatment. She was an active orthodontic patient and had undergone regenerative endodontic treatment for the past 2 years. Clinical examination revealed no response to sensibility, percussion, and palpation tests. The preoperative radiograph showed an open apex and apical rarefaction...

Raman spectroscopy has become an essential technique to characterize and investigate graphene and many other two-dimensional materials. However, there is still a lack of consensus on the Raman signature and phonon dispersion of atomically thin boron nitride (BN), which has many unique properties distinct from graphene. Such a knowledge gap greatly affects the understanding of the basic physical and chemical properties of atomically thin BN as well as the use of Raman spectroscopy to study these nanomaterials...

Some microstructure parameters, such as permeability, remain elusive because mathematical models that express their relationship to the MR signal accurately are intractable. Here, we propose to use computational models learned from simulations to estimate these parameters. We demonstrate the approach in an example which estimates water residence time in brain white matter. The residence time τi of water inside axons is a potentially important biomarker for white matter pathologies of the human central nervous system, as myelin damage is hypothesised to affect axonal permeability, and thus τi...

: Advances in high-throughput sequencing (HTS) technologies have greatly increased the availability of genomic data and potential discovery of clinically significant genomic variants. However, numerous issues still exist with the analysis of these data, including data complexity, the absence of formally agreed upon best practices, and inconsistent reproducibility. Toward a more robust and reproducible variant-calling paradigm, we propose a series of selective noise filtrations and post-alignment quality control (QC) techniques that may reduce the rate of false variant calls...

BACKGROUND/AIM: There is a lack of studies of fractures of the alveolar process (FAP). Only five were published in the last fifty years. The aim of this study was to analyze the risk of pulp necrosis and infection (PN), pulp canal obliteration (PCO), infection-related root resorption (IRR), ankylosis-related resorption (ARR), marginal bone loss (MBL), and tooth loss (TL) as well as to identify the possible risk factors for teeth involved in an isolated alveolar process fracture. In the second part, any late complications of the involved teeth were reported in patients who responded to a follow-up examination...

Objective Bell's palsy is a cranial nerve VII dysfunction that renders the patient unable to control facial muscles from the affected side. Nevertheless, some patients have reported cutaneous changes in the paretic area. Therefore, cutaneous sensibility changes might be possible additional symptoms within the clinical presentation of this disorder. Accordingly, the aim of this research was to investigate the relationship between cutaneous sensibility and facial paralysis severity in these patients. Study Design Prospective longitudinal cohort study...

Misophonia is an affective sound-processing disorder characterized by the experience of strong negative emotions (anger and anxiety) in response to everyday sounds, such as those generated by other people eating, drinking, chewing, and breathing [1-8]. The commonplace nature of these sounds (often referred to as "trigger sounds") makes misophonia a devastating disorder for sufferers and their families, and yet nothing is known about the underlying mechanism. Using functional and structural MRI coupled with physiological measurements, we demonstrate that misophonic subjects show specific trigger-sound-related responses in brain and body...

Metastatic melanoma has been described as a highly aggressive cancer with low sensibility to chemotherapeutic agents. New types of drug, such as metal-based drugs (ferrocifens) have emerged and could represent an alternative for melanoma treatment since they show interesting anticancer potential. Furthermore, molecular analysis has evidenced the role of apoptosis in the low sensibility of melanomas and especially of the key regulator, Bcl-2. The objective of this study was to combine two strategies in the same lipid nanocapsules (LNCs): i) gene therapy to modulate anti-apoptotic proteins by the use of Bcl-2 siRNA, and ii) ferrocifens as a new type of anticancer agent...
