Accuracy and Precision of LASIK Flap Thickness Using the IntraLase Femtosecond Laser in 1000 Consecutive Cases
Authors: Sutton Gerard , Hodge Chris 
Published: September 2019

Purpose
To report the safety and flap thickness predictability of LASIK using the IntraLase femtosecond laser.

Method
A retrospective analysis of 1000 consecutive LASIK cases was performed to assess the rate of intraand postoperative complications and loss of best spectacle-corrected visual acuity (BSCVA). A subset of 260 eyes was prospectively analyzed to assess flap thickness predictability using subtraction ultrasound on the day of surgery.

Results
No serious intra- or postoperative complications were noted. Three (0.3%) patients had epithelial defects that required a bandage contact lens. Four (0.4%) patients had slipped caps on day 1 that required repositioning. Two (0.2%) patients developed grade I diffuse lamellar keratitis. No patient developed epithelial ingrowth >1 mm from the flap edge, transient light sensitivity, or infection. No patient lost ⩾2 lines of BSCVA at 6 months postoperatively. With an attempted flap thickness of 105 µm with the 15-KHz laser, the mean flap thickness was 116.79±10.75 µm (range: 95 to 148 µm) (n=119). In the 30-KHz group (n=141), the target corneal flap thickness was 115 µm, with a mean flap thickness of 114.02±9.82 µm (range: 93 to 163 µm). Overall 87.3% of eyes were within ±20 µm of the intended result. Ninety-eight percent of caps created with the 30-KHz laser were within ±20 µm compared to 74.8% in the 15-KHz group.

Conclusions

LASIK surgery with the IntraLase femtosecond laser is safe and flap thickness is predictable. [

Phakic Toric Implantable Collamer Lens Implantation for the Correction of High Myopic Astigmatism in Eyes With Keratoconus
Authors: Kamiya Kazutaka , Shimizu Kimiya , Ando Wakako , Asato Yoshimori , Fujisawa Tadatoshi 
Published: September 2019

Purpose
To present two patients in whom phakic toric Implantable Collamer Lenses (toric ICL, STAAR Surgical) have been effective for the correction of high myopic astigmatism with stable keratoconus.

Methods
Both patients had a history of contact lens intolerance, and refraction and corneal topography were stable for 3 to 4 years. Preoperatively, the manifest refraction was −10.00 −6.00 ×100 in case 1 and −8.00 −2.75 ×100 in case 2.

Results
Postoperatively, the manifest refraction was +0.50 −1.00 × 90 in case 1 and −0.25 −1.25 × 100 in case 2. Uncorrected visual acuity and best spectacle-corrected visual acuity were markedly improved after implantation in both patients. No progressive sign of keratoconus was seen during 1-year follow-up.

Conclusions

Phakic toric ICL implantation may be an alternative for the correction of high myopic astigmatism in eyes with stable keratoconus. [

Femoral neck prostheses: A systematic analysis of the literature
Authors: Tsitlakidis Stefanos , Westhauser Fabian , Horsch Axel , Beckmann Nicholas , Bitsch Rudi , Klotz Matthias 
Published: September 2019

Primary total hip arthroplasty (THA) is one of the most successful surgical procedures. Considering the demographic change the use of new ultra-short femoral implants has gained importance especially when treating young patients. Main features are bone conservation, metaphyseal anchoring and thus reducing stress shielding by proximal load transferring. The objective of this study is to give an overview over the subject of femoral neck prostheses. A systematic review was conducted. A total number of 27 publications were taken into this systematic review. Over all, just a few follow-up, biomechanical and radiostereometric studies have been conducted in the past. Still no long-term results (>10 years of follow-up) are available. The available mid-term results indicate unsatisfactory survival rates. Aseptic loosening was the most common reason for revision. Valgus angle and good bone mineral density were considered to be crucial for primary stability of femoral neck prostheses. Register data report a very low percentage of femoral neck prostheses in THA with even more diminishing implantation rates. To conclude, further studies are necessary in order to provide evidence-based recommendations. Currently, due to the inhomogeneous and poor data a reasonable and legitimate recommendation cannot be given.
Wearing the Cheongsam
Authors: Sim Cheryl 
Published: September 2019

Associations between the cheongsam dress and Chinese cultural identity are well known but what are the meanings of the cheongsam for members of the Chinese diaspora? In a study grounded in first-hand accounts of wearing, Cheryl Sim explores the practices and experiences of women in Canada, a major Chinese diaspora, and carries out the first in-depth study of the cheongsam from this critical point of view.
Questions explored over the course of 20 interviews, as well as during personal reflections on the author’s own experiences of wearing, include: is there a desire to re-claim or appropriate the cheongsam? Does this desire risk perpetuating stereotypes of Asian women? Does it undermine one’s identification with one’s host country? Can erased heritage(s) be accessed through dress? And how does wearing the cheongsam interact with the male gaze? Revealing feelings of repulsion and attraction, Sim combines personal stories with an authoritative use of theoretical frameworks such as feminism, post-colonialism and autoethnography.
Covering issues such as heritage, ethnic identity, authenticity, nationalism, patriarchy and assimilation, Sim demonstrates that the meanings of the cheongsam are multifarious. Readable but with strong academic underpinnings, this book is the entry point into discussions of Chinese dress and diaspora.
New York New Wave
Authors: Battista Kathy 
Published: September 2019

New York is a centre of creative production for an exciting, emerging generation of women artists. Their work investigates themes such as the body as medium and subject matter; the deconstruction of the existing patriarchal order of the art world; the appropriation of earlier art historical references; and the use of so-called abject and everyday materials.
New York New Wave investigates the relevance of earlier feminist practice for this 'new' generation, asking: Does gender difference still play a role in today's practice? How can younger women artists embrace a radical political ideology and yet remain market friendly? How far have these artists diverged from the established feminist “tradition”? Artists discussed include: Firelei Baez, EV Day, Ruby LaToya Fraser, Diana Al-Hadid, K8 Hardy, Valerie Hegarty, Cindy Hinant, Dawn Kasper, Anya Kielar, Liz Magic Laser, Narcissister, Alix Pearlstein, Aurel Schmidt, AL Steiner and W.A.G.E.
Selective composition modification deposition utilizing ion bombardment-induced interfacial mixing during plasma-enhanced atomic layer deposition
Authors: Hirayama Masaki , Sugawa Shigetoshi 
Published: September 2019

Abstract
We investigated the effects of low-energy (<15 eV) ion bombardment on the properties of Al2O3 plasma-enhanced atomic layer deposition (ALD) films. High-flux ion bombardment caused interfacial mixing with underlying material of Si, and AlSiO
x
films were formed instead of Al2O3 films. The interfacially mixed AlSiO
x
films were selectively formed on single-crystal and amorphous Si surfaces, whereas normal ALD Al2O3 films were formed on SiO2 surfaces. The interfacially mixed AlSiO
x
films possessed thin (∼0.8 nm) SiO
x
interlayers and abrupt interfaces. The interfacial mixing synthesis has the potential to realize simultaneous area and topographically selective depositions in combination with selective etching.

Published: September 2019

AbstractHigh‐performance and flexible supercapacitors (SCs) have great potential for powering wearable and portable devices. Herein, Mo‐doped Co9S8 porous nanosheets on carbon cloth (denoted as Mo–Co–S/CC) are prepared for all‐solid‐state flexible asymmetric SCs via a two‐step method. Na2MoO4 is selected as both Mo source and etching agent to create Mo‐doped porous structure, which provides plenty of reaction sites contributing to the decrease of electrochemical barrier and increase of electrochemical performances. The Mo–Co–S/CC electrode demonstrates a high specific capacity of 771.5 F g−1 at 2 A g−1, excellent rate capability of 660.0 F g−1 at 20 A g−1, and 109% cycling capacitance retention after 30 000 cycles. By using poly(vinyl alcohol)/KOH (PVA/KOH) gel as electrolyte, a flexible all‐solid‐state asymmetric supercapacitor (Mo–Co–S/CC//KOH//AC/CC, FASCs) is assembled, which can work under different bending angles and deliver a specific capacitance of 37.37 F g−1 at 1 A g−1. Furthermore, the FASCs can deliver a maximum energy density of 14.68 Wh kg−1 at power density of 369 W kg−1, with the capacity retention of 80.07% over 30 000 cycles at a high rate of 20 A g−1.
Social contributions to the foraging behavior of young wild golden lion tamarins (Leontopithecus rosalia): Age‐related changes and partner preferences
Authors: Rapaport Lisa G. 
Published: September 2019

AbstractIn cooperatively breeding species, group members other than the parents contribute to the care of the young. The costs and benefits to caregiving may vary with the type of care provided and with caregiver characteristics such as age, sex, reproductive status, and foraging ability. Here I examine the relative contributions of parents, helpers and same‐aged twins to the foraging and feeding activities of the young in a longitudinal study of wild golden lion tamarins, specifically with regard to direct food transfer, tolerance for coforaging or cofeeding by immatures and signaling young as to the location of profitable prey‐foraging sites. I found that the type of food‐related assistance varied as a function of the age of the immature and among group members. Rates of food transfer steadily declined as immatures aged, while coforaging rates peaked when juveniles were in the middle age group. Mothers and fathers were the most generous in terms of providing food to begging young. Mothers most often directed juveniles to productive foraging sites, and female helpers never did. Older siblings did not vary caregiving effort according to sex or age. Adult and subadult foraging ability was not a strong predictor of the rates at which prey was given to the young or the rates at which caregivers tolerated coforaging by immatures on plant and prey resources. Thus, foraging ability did not appreciably influence generosity to or tolerance of the young.

Published: September 2019

AbstractAtroposelective arene formation is an efficient method to build axially chiral molecules with multi‐substituted arenes. Reported here is an organocatalyzed atroposelective arene formation reaction by an N‐heterocyclic carbene (NHC) catalyzed formal [4+2] cycloaddition of conjugated dienals and α‐aryl ketones. This study expands the synthetic potential of NHC organocatalysis and provides a competitive pathway for the synthesis of axially chiral ligands, catalysts, and other functional molecules.

Published: September 2019

AbstractAlkynyl isocyanates have been postulated as highly reactive intermediates in synthetic chemistry. Herein, the parent molecule HC≡CNCO is isolated for the first time. In sharp contrast to the previously reported short lifetime (ca. 15 s) at room temperature, we found that HC≡CNCO has a lifetime of 55 h in the gas phase (2 mbar, 300 K) with a melting point of −79.5 °C and vaporization enthalpy (ΔHvap) of 23.1(1) kJ mol−1. Apart from the IR (gas, solid, and matrix), 1H and 13C NMR, and UV/Vis spectroscopic characterization, its photoisomerization with a acylnitrene HC≡CC(O)N and cyanoketene NCC(H)CO has been observed.

AbstractThe room‐temperature reaction of [Cp*TaCl4] with LiBH4⋅THF followed by addition of S2CPPh3 results in pentahydridodiborate species [(Cp*Ta)2(μ,η2:η2‐B2H5)(μ‐H)(κ2,μ‐S2CH2)2] (1), a classical [B2H5]− ion stabilized by the binuclear tantalum template. Theoretical studies and bonding analysis established that the unusual stability of [B2H5]− in 1 is mainly due to the stabilization of sp2‐B center by electron donation from tantalum. Reactions to replace the hydrogens attached to the diborane moiety in 1 with a 2 e {M(CO)4} fragment (M=Mo or W) resulted in simple adducts, [{(Cp*Ta)(CH2S2)}2(B2H5)(H){M(CO)3}] (6: M=Mo and 7: M=W), that retained the diborane(5) unit.

Published: September 2019

AbstractSoon after their discovery, RNA‐cleaving deoxyribozymes (RCDZ) were explored as anticancer gene therapy agents. Despite low toxicity found in clinical trials, there is no clinically significant anticancer RCDZ‐based therapy. Some of the reported disadvantages of RCDZ agents include poor accessibility to folded nucleic acids, low catalytic efficiency inside cells, and problems of intracellular delivery. On the other hand, structural DNA nanotechnology provides an opportunity to build multifunctional nano‐associations that can address some of these problems. Herein we discuss the possibility of building RCDZ‐based multifunctional DNA nanomachines equipped with RNA unwinding, cancer marker recognition, and RCDZ‐based RNA‐cleavage functions. An important advantage of such “nanomachines” is the possibility to cleave a housekeeping gene mRNA in a cancer‐cell‐specific manner. The proposed design could become a starting point for building sophisticated DNA‐based nanodevices for cancer treatment.
Synthesis of N‐Alkyl and N‐H‐Carbazoles through SNAr‐Based Aminations of Dibenzothiophene Dioxides
Authors: Kaga Atsushi , Nogi Keisuke , Yorimitsu Hideki 
Published: September 2019

AbstractAlkyl amines have become available for the synthesis of diverse N‐alkyl carbazoles through twofold SNAr aminations of dibenzothiophene dioxides by using alkali metal bases. Of particular importance is the choice of counter cations on alkali metal bases, that is, i) the use of Li base for the efficient intermolecular reaction and ii) the sequential addition of heavier alkali metal bases (Na, K, or Cs) to promote intramolecular cyclization in a one‐pot manner. This protocol also enables the cascade synthesis of N‐H‐carbazoles by using 2‐phenylethylamine by removal of the 2‐phenethyl group from N‐(2‐phenethyl) carbazoles in a single operation.

BackgroundFatigue is a common and disabling side effect of targeted therapies such as tyrosine kinase inhibitors (TKIs) used to treat chronic myeloid leukemia (CML). The goal of the current study was to conduct a pilot randomized trial of the first cognitive behavioral intervention developed for fatigue due to targeted therapy.MethodsPatients with CML treated with a TKI who were reporting moderate to severe fatigue were recruited and randomized 2:1 to cognitive behavioral therapy for targeted therapy–related fatigue (CBT‐TTF) delivered via FaceTime for the iPad or to a waitlist control (WLC) group. The outcomes were acceptability, feasibility, and preliminary efficacy for fatigue (Functional Assessment of Chronic Illness Therapy–Fatigue; primary outcome) and quality of life (Functional Assessment of Cancer Therapy–General; secondary outcome). Participants were assessed before randomization and after treatment (ie, approximately 18 weeks later).ResultsA total of 44 patients (mean age, 55 years; 48% female) were assigned to CBT‐TTF (n = 29) or WLC (n = 15). The study participation rate was 59%. Among the patients assigned to CBT‐TTF, 79% completed the intervention. Intent‐to‐treat analyses indicated that patients assigned to CBT‐TTF demonstrated greater improvements in fatigue (d = 1.06; P < .001) and overall quality of life (d = 1.15; P = .005) than those assigned to WLC. More patients randomized to CBT‐TTF than WLC demonstrated clinically significant improvements in fatigue (85% vs 29%) and quality of life (88% vs 54%; P values ≤ .016).ConclusionsCBT‐TTF displays preliminary efficacy in improving fatigue and quality of life among fatigued patients with CML treated with TKIs. The findings suggest that a larger randomized study is warranted.

Published: September 2019

AbstractRoom‐temperature sodium–sulfur (RT−Na/S) batteries hold great promise to meet the requirements of large‐scale energy storage due to their high theoretical energy density, low material cost, resource abundance, and environmental benignity. However, the poor cycle performance and low utilization of active sulfur greatly hinder their practical application. As the essential part directly related to the battery performance, the S‐based cathode has attracted tremendous research interests in recent years. This review highlights recent progress in cathode materials for RT−Na/S batteries. Particularly, basic insights into the Na/S reaction mechanism are presented and representative works on S‐based cathode materials are systematically summarized. The remaining challenges and developing trends of RT−Na/S batteries are also discussed. We hope this review can shed light on the field of next‐generation metal‐sulfur batteries.

Background and Aims
We describe the pathophysiology, treatment, and outcome of Crigler‐Najjar type 1 syndrome (CN1) in 28 UGT1A1 c.222C>A homozygotes followed for 520 aggregate patient‐years.

Approach and Results
Unbound (“free”) bilirubin (Bf) was measured in patient sera to characterize the binding of unconjugated bilirubin (BT) to albumin (A) and validate their molar concentration ratio (BT/A) as an index of neurological risk. Two custom phototherapy systems were constructed from affordable materials to provide high irradiance in the outpatient setting; light dose was titrated to keep BT/A at least 30% below intravascular BT binding capacity (i.e., BT/A = 1.0). Categorical clinical outcomes were ascertained by chart review, and a measure (Lf) was used to quantify liver fibrosis. Unbound bilirubin had a nonlinear relationship to BT (R2 = 0.71) and BT/A (R2 = 0.76), and Bf as a percentage of BT correlated inversely to the bilirubin–albumin equilibrium association binding constant (R2 = 0.69), which varied 10‐fold among individuals. In newborns with CN1, unconjugated bilirubin increased 4.3 ± 1.1 mg/dL per day. Four (14%) neonates developed kernicterus between days 14 and 45 postnatal days of life; peak BT ≥ 30 mg/dL and BT/A ≥ 1.0 mol:mol were equally predictive of perinatal brain injury (sensitivity 100%, specificity 93.3%, positive predictive value 88.0%), and starting phototherapy after age 13 days increased this risk 3.5‐fold. Consistent phototherapy with 33‐103 µW/cm2•nm for 9.2 ± 1.1 hours/day kept BT and BT/A within safe limits throughout childhood, but BT increased 0.46 mg/dL per year to reach dangerous concentrations by 18 years of age. Liver transplantation (n = 17) normalized BT and eliminated phototherapy dependence. Liver explants showed fibrosis ranging from mild to severe.

Conclusion
Seven decades after its discovery, CN1 remains a morbid and potentially fatal disorder.

AbstractCell therapy combined with biomaterial scaffolds is used to treat cartilage defects. We hypothesized that chondrogenic differentiation bone marrow‐derived mesenchymal stem cells (BM‐MSCs) in three‐dimensional biomaterial scaffolds would initiate cartilaginous matrix deposition and prepare the construct for cartilage regeneration in situ. The chondrogenic capability of human BM‐MSCs was first verified in a pellet culture. The BM‐MSCs were then either seeded onto a composite scaffold rhCo‐PLA combining polylactide and collagen type II (C2) or type III (C3), or commercial collagen type I/III membrane (CG). The BM‐MSCs were either cultured in a proliferation medium or chondrogenic culture medium. Adult human chondrocytes (ACs) served as controls. After 3, 14, and 28 days, the constructs were analyzed with quantitative polymerase chain reaction and confocal microscopy and sulfated glycosaminoglycans (GAGs) were measured. The differentiated BM‐MSCs entered a hypertrophic state by Day 14 of culture. The ACs showed dedifferentiation with no expression of chondrogenic genes and low amount of GAG. The CG membrane induced the highest expression levels of hypertrophic genes. The two different collagen types in composite scaffolds yielded similar results. Regardless of the biomaterial scaffold, culturing BM‐MSCs in chondrogenic differentiation medium resulted in chondrocyte hypertrophy. Thus, caution for cell fate is required when designing cell‐biomaterial constructs for cartilage regeneration.
