"this review will focus on corneal - based surgical strategies to treat presbyopia and in particular how these methods have been or may be used in pseudophakic patients . to improve uncorrected near vision in presbyopia , the two major techniques to alter the cornea generally utilize either an intracorneal inlay device or laser refractive surgery .",
"laser blended vision treatment seems to provide the best compromise in terms of safety and quality of vision .",
"since presbyopia is caused by progressive elasticity changes in the biological crystalline lens , presbyopic surgeries may either directly replace the lens through an intraocular approach or modify extraocular structures such as the cornea or sclera .",
"corneal inlays are devices that are surgically placed within the corneal stroma of the nondominant eye to change the optical properties of the cornea .",
"one of the most popular techniques , laser - assisted in situ keratomileusis ( lasik ) , removes corneal stromal tissue under an anterior flap ."

"these anecdotes suggest that cataract surgery can still be successfully performed after inlay implantation , which will be important for those young presbyopes opting for surgical treatment of their presbyopia .",
"four of these patients also underwent simultaneous lasik to optimize their underlying refractive error prior to insertion of a kamra pinhole inlay .",
"there are several case reports describing the opposite sequence of events , where patients with prior corneal inlay implantation subsequently undergo cataract extraction with intraocular lens placement , either with or without initially removing the inlay .",
"these patients had previously received any one of the three major corneal inlay types , including the kamra inlay , presbia microlens inlay , and the raindrop near vision inlay ."

"an extensive review of the literature on laser refractive surgery for presbyopia revealed very few studies done in pseudophakic patients , although there are numerous published accounts in phakic patients .",
"various studies examine the efficacy of laser refractive surgery on treating presbyopia in phakic patients .",
"nonetheless , laser refractive surgery has been performed successfully on pseudophakes to correct for ametropias [ 2225 ] , suggesting that laser refractive surgery to address presbyopia is likely to be equally successful in pseudophakic patients who have monofocal iols . clearly , the application of laser refractive surgery to presbyopia in pseudophakia merits more research .",
"similar to the body of literature on corneal inlays , a history of prior intraocular surgery such as cataract extraction typically excluded such patients from studies on laser refractive surgery for presbyopia ."
],
[
"some of the challenges stem from the prior intraocular surgery itself , such as navigating corneal scars and residual corneal irregularities from prior incisions .",
"although corneal inlays are promoted as removable , long - term follow - up on removed inlays is not available and presbylasik procedures are in general not reversible with the commonly available technology at present . as the first wave of refractive patients begins to require cataract surgery , we may be required to change not only the assessment and technique of cataract surgery for these patients , but also how we counsel these patients who have high expectations for visual acuity and spectacle independence .",
"additionally , iol aberrations may alter laser refractive measurements and calculations normally used on phakic eyes .",
"studies have suggested that the final uncorrected visual acuity after excimer laser or corneal inlay surgery is lower in pseudophakic patients than in typical refractive patients . on the other hand ,",
"it is worth noting , however , that because the iol treats most of the spherical error in pseudophakic patients , there would be less keratorefractive - induced effect on the corneal prolate asphericity and quality of vision than in nonametropic phakic patients . in all patients , regardless of phakic status , there are certain considerations to optimize a satisfactory outcome from corneal - based presbyopic surgeries .",
"presbyopic surgery may not completely eliminate the need for reading glasses . given the necessity of fundus viewing for diagnosis and treatment of diseases such as age - related macular degeneration , diabetic retinopathy , or retinal detachments"
],
[
"nevertheless , presbyopic surgeries will not be ideal for all patients , and appropriately screening patients and managing patient expectations are both key to maximizing satisfactory outcomes .",
"pseudophakic patients who still desire better uncorrected near vision may choose corneal - based surgical therapies , such as corneal inlays or laser refractive surgery .",
"many studies on presbyopic surgeries excluded patients with prior ocular surgery , and the few published studies on pseudophakic patients are limited by short - term follow - up , small numbers , and limited lighting conditions .",
"for patients suffering from presbyopia , there are now exciting surgical alternatives to glasses and contact lenses .",
"undoubtedly , there is a pressing need for more research on presbyopic surgeries in the pseudophakic population ."

] | purpose . the purpose of this review is to provide a summary of laser refractive surgery and corneal inlay approaches to treat presbyopia in patients after cataract surgery . summary . the presbyopic population is growing rapidly along with increasing demands for spectacle independence . this review will focus on the corneal - based surgical options to address presbyopia including various types of corneal intrastromal inlays and laser ablation techniques to generate either a multifocal cornea ( presbylasik ) or monovision . the natural history of presbyopia develops prior to cataracts , and these presbyopic surgeries have been largely studied in phakic patients . nevertheless , pseudophakic patients may also undergo these presbyopia - compensating procedures for enhanced quality of life . this review examines the published reports that apply these technologies to patients after cataract surgery and discusses unique considerations for this population . |

on opening of the double bond . another property , the thermal dissociation
of the c = c bond , has been explained by the stabilization of
the product ( cf2 ) by back - bonding . here , it is attempted
to correlate such properties with vibrational constants , in particular
for c = c stretching and twisting and for carbon pyramidalization . the only force constant found to be lowered compared to ethylene is
that for trans pyramidalization ( 8 ) , and cc bond
softening on 8 distortion is indicated by the conspicuously
large magnitude of anharmonic constant , x18 . both observations can be rationalized by a valence - bond model that
predicts a trans bent structure on weakening the cc bond . conclusions

] | [ purpose ] this study investigated the effect of the use of trekking poles on muscle and
cartilage damage and fatigue during downhill walking in obese women . [ subjects and
methods ] subjects included eight obese women who had a body fat percentage greater than
30 . subjects performed downhill walking without a trekking pole ( np ) and with a trekking
pole ( tp ) at 50% heart rate reserve for 30 minutes on a treadmill . the treadmill was set
at a 15% downhill declination . blood samples were collected to examine muscle damage
( serum creatine kinase [ ck ] and lactate dehydrogenase [ ldh ] levels ) , cartilage damage
( serum cartilage oligomeric matrix protein [ comp ] levels ) , and fatigue ( plasma lactate
levels ) at the pre - walking baseline ( pwb ) , immediately after walking ( iaw ) , and 2 hours
post - walking ( 2hpw ) . [ results ] the ck , ldh , comp , and lactate levels were significantly
increased iaw when compared with those at the pwb in both trials . in addition , in the np
trial , the ck , ldh , and comp levels were significantly increased at 2hpw when compared
with those at the pwb . [ conclusion ] downhill walking can cause muscle and cartilage
damage , and our results suggest that the use of a trekking pole can reduce temporary
muscle and cartilage damage after downhill walking . |

"the public health costs attributed to unintended births in a single year cost taxpayers $ 11.1 billion ( 2006).6 furthermore , previous studies have reported that ups are more likely to result in preterm births and low - birth - weight babies , which would increase health costs for neonatal care and costs associated with long - term disabilities.7 this is particularly relevant for ups in adolescence , which are more likely to result in low - birth - weight births , which can increase health costs.8 over the past few decades , brazil , like many fast - emerging economies , has experienced a fertility transition noted by a dramatic reduction in the total fertility rate , which currently sits at 1.8 births per woman.9,10 furthermore , during the fertility transition , the rate of contraception has also increased.11 despite increased contraception use , the cumulative rate of spontaneous and induced abortion changed very little between 1996 and 2006 , for which population survey estimates are available.12,13 furthermore , a survey of more than 1,000 women aged 1024 years in a single postnatal unit in brazil reported that more than 50% of all births were unintended , suggesting that possibly significant unmet contraception need still exists.8 similarly , for the whole country , the data from the last demographic and health survey ( dhs ) performed in 2006 indicates that 55% of all births were unintended.14 prevention of up using publicly funded programs in high - income countries has proven to generate significant cost savings for health services and public services.15 previous economic studies evaluating the consequences of up have mostly been performed in high - income countries where publicly funded fertility services and abortion legislation are different from those in low-/middle - income countries.15 the aim of this study was to evaluate the cost consequences of up in brazil , an emerging economy with vastly different fertility planning services than most advanced economies and with restrictive abortion laws . to the best of our knowledge ,",

] | in the wake of the ongoing 2014/2015
ebola virus outbreak , significant
questions regarding the appropriate handling of ebola virus - contaminated
liquid waste remain , including the persistence of ebola virus in wastewater . to address these uncertainties , we evaluated the persistence of ebola
virus spiked in sterilized domestic sewage . the viral titer decreased
approximately 99% within the first test day from an initial viral
titer of 106 tcid50 ml1 ;
however , it could not be determined if this initial rapid decrease
was due to aggregation or inactivation of the viral particles . the
subsequent viral titer decrease was less rapid , and infectious ebola
virus particles persisted for all 8 days of the test . the inactivation
constant ( k ) was determined to be 1.08 ( 2.1
days for a 90% viral titer decrease ) . due to experimental conditions ,
we believe these results to be an upper bound for ebola virus persistence
in wastewater . wastewater composition is inherently heterogeneous ;
subsequently , we caution that interpretation of these results should
be made within a holistic assessment , including the effects of wastewater
composition , dilution , and potential exposure routes within wastewater
infrastructure . while it remains unknown if ebola virus may be transmitted
via wastewater , these data demonstrate a potential exposure route
to infectious ebola virus via wastewater and emphasize the value of
a precautionary approach to wastewater handling in an epidemic response . |

"this article will not significantly address the sociology of psychostimulant abuse , which involves diverse events ranging from the use of amphetamines by japanese soldiers in world war ii , to the formulation of crack as a less expensive version of cocaine in the united states , to the introduction of prescription formulations to regulate eating habits or to treat attention deficit - hyperactivity disorder . ",
"however , the appearance of these substances in western societies has been relatively recent , cocaine having debuted as both a local anesthetic and a psychostimulant in the 19th century . over the course of the next century , it became increasingly clear that the amphetamine - like psychostimulants carried serious abuse liability , as well as producing a prominent paranoia - like syndrome among many individuals who chronically used this class of drugs .",
"cocaine and other amphetamine - like psychostimulants have been a significant part of the human pharmacopoeia for thousands of years .",
"rather , we will review the basic pharmacology of amphetamine - like drugs , integrate these molecular mechanisms into the brain circuitry of reward , and describe how these drugs are thought to create pathological changes in reward and learning circuitry finally , this knowledge will be amalgamated into a vision of future pharmacotherapies for treating psychostimulant addiction .",
"the abuse liability of these drugs has resulted in sociological use patterns that have been described as epidemics , such as the methamphetamine epidemic in japan in the 1950s , the cocaine epidemic in the united states in the 1980s , and the crack cocaine epidemic of the 1990s . \n ",
"the high abuse liability of this class of drugs relies on both pharmacological properties and the sociological characteristics of how the drugs are introduced into various societies around the world ."
],
[
"the defining mechanism of action of amphetamine4ike psychostimulants as a class of drugs with high abuse liability is the ability to bind to dopamine transporters ( dat ) .",
", this class of drugs dramatically elevates extracellular dopamine , and this action is thought to be the initiating molecular event that reinforces drugseeking behaviors , ultimately culminating in addiction . \n",
"dopamine transporters are a member of a class of proteins that eliminate monoamines , including dopamine , from the synaptic cleft after neuronal release ."
],
[
"thus , the neutral stimulus now causes dopamine release in a manner predicting arrival of a motivationally relevant event . based upon these data , the role for dopamine release in the mesocorticolimbic brain regions is twofold : ( i ) to cue the organism that a novel motivationally relevant event is occurring and that adaptive behavioral responses need to be engaged ( eg , approach a reward or avoid a stress ) ; ( ii ) once the behavioral response is established , dopamine release is antecedent to the appearance of the motivationally relevant event and is triggered by environmental associations that the organism has made with the event as part of learning the adaptive behavioral response . in this way , dopamine serves to alert and thereby prepare the organism for an impending important event .",
"an important characteristic of this brain - environment interaction is that the ability of a given stimulus to increase dopamine cell firing and release decreases with repeated presentation of the stimulus .",
"however , it can be shown that if a motivationally neutral stimulus ( such as a light or tone ) is associated with the motivational event in such a manner that the neutral stimulus predicts arrival of the motivational event , the ability of the motivational stimulus to release dopamine is transferred to the neutral stimulus .",
"it is this overlearning of drugseeking behaviors by progressive associations formed between repeated drug - induced dopamine release and the environment that is thought to lead to increased vulnerability to relapse ."
],
[
"a variety of studies have linked this activation of corticofugal glutamate transmission with craving in psychostimulant addicts or drug - seeking in animal models of addiction .",
"thus , relapse can be induced by dopamine release in prefrontal and allocortical brain regions , and reflects the aforementioned physiological role of dopamine release as a predictive antecendent to stimulus ( drug ) delivery .",
"what this implies is that chronic release of dopamine by repeated psychostimulant administration may be modifying cortical and allocortical regulation of behavior . \n",
"this possibility is supported by animal models in two ways : ( i ) if animals that have been trained to self - administer cocaine are left in abstinence for an extended period , drug - seeking is augmented , and in this case inhibition of the prefrontal cortex or amygdala no longer inhibits drug - seeking induced by drug - associated stimuli . however , inhibition of the dorsolateral striatum is still effective at blocking drug - seeking ; ( ii ) as training of an animal in drug - seeking paradigms progresses it is possible to show a gradual increase in dopamine released into the caudate in favor of release into the nucleus accumbens .",
"as outlined above , psychostimulant - induced dopamine release is responsible for reinforcing behaviors designed to seek and administer the drugs ."
],
[
"given the apparent critical role played by glutamatergic affrents to the nucleus accumbens in initiating drugseeking or craving , recent studies have identified a number of enduring cellular changes in glutamate transmission that may be critical pathological neuroadaptations to psychostimulant use , and may serve as targets for pharmcotherapeutic intervention . in general",
"thus , the large psychostimulant - induced release of glutamate has been hypothesized to be a pathological and perhaps critical mediator of relapse .",
"thus , there remain many apparent contradictions in the literature regarding changes in specific proteins , and in the overall direction of synaptic grading ( ie , is postsynaptic glutamate transmission augmented or inhibited by chronic psychostimulant administration ) .",
"as mentioned above , drug - seeking is associated with a large release of prefrontal glutamate into the nucleus accumbens ."
],
[
"pharmacotherapeutic targets for regulating the pathological synaptic glutamate release seen in the accumbens of psychostimulant - seeking animals can be placed into two categories : ( i ) targets based upon psychostimulant induced changes in proteins regulating synaptic glutamate release ; ( ii ) proteins that produce a general decrease in excitatory transmission .",
"the primary drugs in the category of nonspecific inhibitors of synaptic glutamate release include a variety of -aminobutyric acid ( gaba)-mimetic compounds .",
"as outlined above , given our current state of knowledge it is more likely that pharmacotherapeutic restoration of normal glutamate release may be a more successful approach than manipulating postsynaptic proteins responsible for and/or associated with changes in the fidelity of postsynaptic glutamate transmission . in part , this is due to the relatively contradictory status of the emerging literature on postsynaptic plasticity .",
"these range from relatively specific agonists at gabab receptors , such as baclofen , which inhibit synaptic glutamate release to a host of less selective compounds known to increase gaba transmission via interactions with synthetic or elimination mechanisms , such as topiramate or vigabatrin ."
],
[
"this review has endeavored to transport the reader from the initiating molecular actions of amphetamine - like psychostimulants on dopamine systems in the brain to enduring neuroplasticity produced in glutamate transmission responsible for communicating from prefrontal and allocortical brain regions through the nucleus accumbens to motor regulatory systems . moreover , by examining molecular neuroplasticity produced in excitatory synapses by chronic psychostimulant administration , it is possible to make some deductions about potential pharmacotherapeutic interventions .",
"indeed , there already exists an emerging literature supporting this approach in developing potential pharmacotherapies for treating psychostimulant addiction .",
"importantly , this is a nascent and emerging science , and while much has been discovered , the cutting edge of discovery into the neuroplasticity produced by psychostimulants is understandably contradictory . as further discoveries are made that allow us to understand the nature of these contradictions , it should follow that additional targets will emerge to provide potential novel pharmacotherapies for treating psychostimulant addiction ."
]
] | although the pharmacology of amphetamine - like psychostimulants at dopamine transporters is well understood , addiction to this class of drugs has proven difficult to deal with . the reason for this disconnection is that while the molecular mechanism of amphetamine action is critical to reinforce drug use , it is only the first step in a sequence of widespread neuroplastic events in brain circuitry . this review outlines the affect of psychostimulants on mesocorticolimbic dopamine projections that mediate their reinforcing effect , and how this action ultimately leads to enduring pathological neuroplasticity in glutamatergic projections from the prefrontal cortex to the nucleus accumbens . molecular neuroadaptations induced by psychostimulant abuse are described in glutamate neurotransmission , and from this information potential pharmacotherapeutic targets are identified , based upon reversing or countermanding psychostimulant - induced neuroplasticity . |

"we recently demonstrated that following neonatal hypoxia with unilateral transient ischemia there is evidence for early wallerian degeneration visible as either decreases in the apparent diffusion coefficient ( adc ) and magnetization transfer ratio or increases in dw or t2 ( lama et al ."

"these regions of interest were manually defined in the mr images and histological sections and included the cerebral peduncle ( 0.30.4 mm ) , pons ( within the central gray and mesencephalic trigeminal nucleus regions , 0.60.9 mm ) and parietal cortex ( 0.71.0 mm ) for areas both ipsilateral and contralateral to the lesion containing hemisphere . once the ischemic infarct had progressed towards cavitation and cyst formation ( i.e. 1 and 4 w post - hypoxia ischemia ) , homologous measures of cortical tissue were not possible and therefore were taken adjacent to the cyst a peri - cyst cortical region ( 0.40.6 mm ) .",
"brains from 44 rats were processed and stained for 5 different cellular or injury markers within sections containing the parietal cortex , posterior cerebral peduncle and central gray region of the pons .",

"thus , this systematic study is informative regarding the optimal dti mr imaging parameters to probe axonal injury following hypoxic / ischemic brain damage in developing brain in addition to aiding our interpretation of dti parameters for detecting various stages of wallerian degeneration .",
"the results are first to characterize the correspondence of the progression of cellular and dti changes within the cerebral peduncle of the descending corticospinal tract following hypoxic ischemic damage to the cortex .",
"novel is the demonstration of the differing progression of dti alterations in a directly damaged ischemic region such as parietal cortex versus that in associated subcortical tracts .",
"the results demonstrate that in general , diffusivity changes and histological responses within directly damaged ischemic brain precede and are often larger in magnitude than corresponding alterations in a region of secondary axonal degeneration , such as the cerebral peduncle . with the progression of damage over one or more weeks , dti components such as fa and radial diffusivity are better than mean adc for detecting ischemia associated axonal injury indicative of wallerian degeneration ."

] | ischemically damaged brain can be accompanied by secondary degeneration of associated axonal connections e.g. wallerian degeneration . diffusion tensor imaging ( dti ) is widely used to investigate axonal injury but the cellular correlates of many of the degenerative changes remain speculative . we investigated the relationship of dti of directly damaged cerebral cortex and secondary axonal degeneration in the cerebral peduncle with cellular alterations in pan - axonal neurofilament staining , myelination , reactive astrocytes , activation of microglia / macrophages and neuronal cell death . dti measures ( axial , radial and mean diffusivity , and fractional anisotropy ( fa ) ) were acquired at hyperacute ( 3 h ) , acute ( 1 and 2 d ) and chronic ( 1 and 4 week ) times after transient cerebral hypoxia with unilateral ischemia in neonatal rats . the tissue pathology underlying ischemic and degenerative responses had a complex relationship with dti parameters . dti changes at hyperacute and subacute times were smaller in magnitude and tended to be transient and/or delayed in cerebral peduncle compared to cerebral cortex . in cerebral peduncle by 1 d post - insult , there were reductions in neurofilament staining corresponding with decreases in parallel diffusivity which were more sensitive than mean diffusivity in detecting axonal changes . ipsilesional reductions in fa within cerebral peduncle were robust in detecting both early and chronic degenerative responses . at one or four weeks post - insult , radial diffusivity was increased ipsilaterally in the cerebral peduncle corresponding to pathological evidence of a lack of ontogenic myelination in this region . the detailed differences in progression and magnitude of dti and histological changes reported provide a reference for identifying the potential contribution of various cellular responses to fa , and , parallel , radial , and mean diffusivity . |

] | dinoflagellate plastid genes are believed to be encoded on small generally unigenic plasmid - like minicircles . the minicircle gene complement has reached saturation with an incomplete set of plastid genes ( 18 ) compared with typical functional plastids ( 60200 ) . while some of the missing plastid genes have recently been found in the nucleus , it is still unknown if additional genes , not located on minicircles , might also contribute to the plastid genome . sequencing of tailed rna showed that transcripts derived from the known minicircle genes psba and atpb contained a homogenous 3 polyuridine tract of 2540 residues . this unusual modification suggested that random sequencing of a poly(da ) primed cdna library could be used to characterize the plastid transcriptome . we have recovered only 12 different polyuridylylated transcripts from our library , all of which are encoded on minicircles in several dinoflagellate species . the correspondence of all polyuridylylated transcripts with previously described minicircle genes thus supports the dinoflagellate plastid as harbouring the smallest genome of any functional chloroplast . interestingly , northern blots indicate that the majority of transcripts are modified , suggesting that polyuridylylation is unlikely to act as a degradation signal as do the heterogeneous poly(a)-rich extensions of transcripts in cyanobacteria and other plastids . |

] | objectives : opioids such as morphine form the cornerstone in the treatment of moderate to severe pain . however , opioids also produce serious side effects such as tolerance . fosaprepitant is a substance p ( sp ) receptor antagonist , which is used for treating chemotherapy - induced nausea and vomiting . sp is an important neuropeptide mediating transmission of pain at the spinal level . thus , it was hypothesized that combining morphine with fosaprepitant would increase the antinociceptive effect of morphine . the objectives were to evaluate the effect of fosaprepitant on morphine - induced antinociception in rats and to investigate its mechanism of action.methods:sprague-dawley rats were injected with morphine ( 10 mg / kg twice daily ) and/or fosaprepitant ( 30 mg / kg once daily ) for 7 days . pain threshold was assessed by the hot plate test . expression of sp and calcitonin gene - related peptide ( cgrp ) in the spinal cords of these rats was evaluated by immunohistochemistry.results:morphine administration resulted in an antinociceptive effect compared to the control group ( day 1 and to a lesser extent on day 4 ) . the decreased antinociception despite continued morphine treatment indicated development of tolerance . co - administration of fosaprepitant attenuated tolerance to morphine ( days 1 and 3 ) and increased the antinociceptive effect compared to control group ( days 14 ) . expression of sp was increased in the morphine + fosaprepitant group.conclusions:the results show that fosaprepitant attenuates the development of tolerance to morphine and thereby , increases the antinociceptive effect . this is likely linked to decreased release of sp from presynaptic terminals . |

and overall hydrogen production when compared to a reference system
