Masalah seks di kalangan remaja merupakan permasalahan bersama di dalam kehidupan masyarakat, karena erat kaitannya dengan adat istiadat dan moralitas yang merupakan ukuran baik dan buruk di dalam kehidupan masyarakat. Usia remaja merupakan masa dimana terjadi perkembangan hormone seksual yang akan memberikan pengalaman-pengalaman baru bagi remaja itu sendiri. Pengalaman baru ini akan menimbulkan rasa ketertarikan dengan lawan jenis yang akhirnya mendorong remaja berkeinginan melakukan hubungan seksual pra nikah. Hal ini juga di pengaruhi oleh rasa ingin tahu tentang seks yang menurut remaja hanya sebatas pada organ seks dan mencoba mencari cara untuk memenuhi hasratnya misalnya masturbasi, bercumbu dan bersenggama. Hanya beberapa remaja yang berharap pengetahuan tentang seks di pelajari dari orang tua. Penelitian ini bersifat deskriptif kualitatif dimana menggambarkan perilaku seksualitas remaja di lingkungan VI Kelurahan Binjai Kecamatan Medan Denai dengan jumlah sample yang di ambil adalah 67 orang remaja. Pengolahan data dilakukan dengan menggunakan teknik penentuan skala likert yang mempunyai 2 kategori yaitu kriteria baik dan kriteria kurang baik. Hasil dari penelitian ini adalah dimana tingkat pengetahuan, sikap dan tindakan seksualitas remaja di Lingkungan VI Kelurahan Binjai Kecamatan Medan Denai termasuk kedalam kriteria baik dengan jumlah 52 orang (77,61%) sedangkan yang termasuk kriteria kurang baik hanya berjumlah 15 orang (22,38%). Sehingga jelaslah masih tingginya kesadaran dan baiknya perilaku remaja di lingkungan VI Kelurahan Binjai Kecamatan Medan Denai. Yang paling dominan pada hasil penelitian ini adalah telah didapatnya penerangan/ pengetahuan tentang seks kepada remaja yang menjawab ya sebanyak 67 orang (100 %).

Published: April 2019

Abstract
The impact of active galactic nuclei (AGNs) on star formation has implications for our understanding of the relationships between supermassive black holes and their galaxies, as well as for the growth of galaxies over the history of the universe. We report on a high-resolution multiphase study of the nuclear environment in the nearby Seyfert galaxy NGC 2110 using the Atacama Large Millimeter/submillimeter Array, Hubble and Spitzer Space Telescopes, and the Very Large Telescope/SINFONI. We identify a region that is markedly weak in low-excitation CO

emission from cold molecular gas, but appears to be filled with ionized and warm molecular gas, which indicates that the AGN is directly influencing the properties of the molecular material. Using multiple molecular gas tracers, we demonstrate that, despite the lack of CO line emission, the surface densities and kinematics of molecular gas vary smoothly across the region. Our results demonstrate that the influence of an AGN on star-forming gas can be quite localized. In contrast to widely held theoretical expectations, we find that molecular gas remains resilient to the glare of energetic AGN feedback.
Deep Intrastromal Arcuate Keratotomy With In Situ Keratomileusis (DIAKIK) for the Treatment of High Astigmatism After Keratoplasty: 2-Year Follow-up
Authors: Drouglazet-Moalic Gwenola , Levy Ora , Goemaere Isabelle , Borderie Vincent , Laroche Laurent , Bouheraoua Nacim 
Published: April 2019

PURPOSE:
To describe 2-year results of deep intrastromal arcuate keratotomy with in situ keratomileusis (DIAKIK) for the treatment of high astigmatism after keratoplasty.

METHODS:
This prospective study included 20 eyes from 20 patients presenting with high astigmatism after keratoplasty. All were treated by two-step femtosecond laser surgery, with two intrastromal arcuate keratotomies and a corneal flap, followed a few months later by excimer photoablation after reopening of the flap.

RESULTS:

At 24 months, both uncorrected (UDVA) and corrected (CDVA) distance visual acuity had improved from 1.12 ± 0.42 logMAR (20/200 Snellen) before surgery to 0.58 ± 0.23 logMAR (20/80 Snellen) (
P
< .001) and from 0.31 ± 0.26 logMAR (20/40 Snellen) to 0.20 ± 0.20 logMAR (20/32 Snellen) (
P
= .04), respectively. The mean spherical equivalent improved from −5.01 ± 4.35 to −1.54 ± 2.42 diopters. The mean efficacy index was 0.63. The mean correction index was 0.93 ± 0.32. The mean flattening index was 1.09 ± 0.75 and the mean safety index was 1.39. No graft rejection or epithelial ingrowth was observed.

CONCLUSIONS:
This two-step procedure was an effective treatment for high astigmatism after keratoplasty. The use of both femtosecond and excimer lasers helped to avoid some complications that would have jeopardized the grafts. Refractive and topographic stability was good 2 years after surgery.

Biomechanical Impact of Localized Corneal Cross-linking Beyond the Irradiated Treatment Area
Authors: Webb Joshua N. , Langille Erin , Hafezi Farhad , Randleman J. Bradley , Scarcelli Giuliano 
Published: April 2019

PURPOSE:
To investigate the stiffening effect of localized corneal cross-linking (L-CXL) within and beyond the irradiated region in three dimensions.

METHODS:
Ten porcine eyes were debrided of epithelium and incrementally soaked with 0.1% riboflavin solution. Using a customized, sharp-edged mask, half of the cornea was blocked while the other half was exposed to blue light (447 nm). The three-dimensional biomechanical properties of each cornea were then measured via Brillouin microscopy. An imaging system was used to quantify the optimal transition zone between cross-linked and non-cross-linked sections of the cornea when considering light propagation and scattering.

RESULTS:
A broad transition zone of 610 µm in width was observed between the fully cross-linked and non-cross-linked sections, indicating the stiffening response extended beyond the irradiated region. Light propagation and the scattering induced by the riboflavin-soaked cornea accounted for a maximum of 25 and 159 ± 3.2 µm, respectively.

CONCLUSIONS:
The stiffening effect of L-CXL extends beyond that of the irradiated area. When considering L-CXL protocols clinically, it will be important to account for increased stiffening in surrounding regions.

Comparison of Wavefront-Optimized Ablation and Topography-Guided Contoura Ablation With LYRA Protocol in LASIK
Authors: Ozulken Kemal , Yuksel Erdem , Tekin Kemal , Kiziltoprak Hasan , Aydogan Semih 
Published: April 2019

PURPOSE:
To compare the refractive outcomes and aberration data analysis of wavefront-optimized (WFO) ablation and topography-guided Contoura ablation (TGCA) (Contoura on the WaveLight laser; WaveLight GmbH, Erlangen, Germany) in patients who had laser-assisted in situ keratomileusis (LASIK) for myopia or myopic astigmatism.

METHODS:

In this comparative contralateral eye study, patients who underwent LASIK with TGCA in one eye and with WFO ablation in the fellow eye were analyzed. Aberration measurements and corneal topography were analyzed using the WaveLight Oculyzer II diagnostic device (Alcon Laboratories, Inc., Fort Worth, TX). Total corneal higher order aberrations (HOAs) including vertical and oblique astigmatism (Z

), trefoil (Z

), spherical aberration, and Q value were analyzed. These measurements were taken preoperatively and 3 months postoperatively.

RESULTS:

This study comprised 32 patients. There were no significant differences between both procedures according to postoperative uncorrected and corrected distance visual acuity values, refractive errors, and manifest refraction spherical equivalents within ±0.50 diopters (D) of emmetropia (
P
> .05). The preoperative corneal HOAs and Q values were also similar between the groups (
P
> .05). At 3 months postoperatively, the vertical and horizontal coma values in the WFO ablation group were statistically significantly higher compared to the TGCA group (
P
= .013 and .020, respectively). Less stromal tissue was ablated in the TGCA group compared to the WFO ablation group (
P
< .001).

CONCLUSIONS:
Although WFO ablation and TGCA protocols had statistically similar visual outcomes, the TGCA protocol was associated with a significantly lower induction in vertical and horizontal coma and smaller amount of tissue ablation compared to WFO ablation.

Functional Optical Zone and Centration Following SMILE and LASIK: A Prospective, Randomized, Contralateral Eye Study
Authors: Damgaard Iben B. , Ang Marcus , Mahmoud Ashraf M. , Farook Mohamed , Roberts Cynthia J. , Mehta Jodhbir S. 
Published: April 2019

PURPOSE:
To compare centration and functional optical zone (FOZ) after small incision lenticule extraction (SMILE) and femtosecond laser–assisted in situ keratomileusis (LASIK).

METHODS:
In this prospective, randomized, single-masked, paired-eyed, clinical trial, 70 patients received SMILE in one eye and LASIK in the other eye for myopia and myopic astigmatism. FOZ was calculated using custom software on 3-month postoperative refractive power maps (Pentacam HR; Oculus Optikgeräte GmbH, Wetzlar, Germany). Programmed treatment area was defined as the total area of the programmed OZ plus the transition zone. Centration was evaluated by the linear distance between FOZ centroid and the pupil center and the corneal apex.

RESULTS:

The average preoperative spherical equivalent (−5.38 ± 1.65 vs −5.45 ± 1.61 diopters [D]), postoperative spherical equivalent (0.05 ± 0.39 vs 0.06 ± 0.39 D), uncorrected distance visual acuity (0.01 ± 0.13 vs 0.00 ± 0.08 logMAR), and corrected distance visual acuity (−0.07 ± 0.10 vs −0.07 ± 0.10 logMAR) were comparable in SMILE- and LASIK-treated eyes of the 60 patients with complete datasets (
P
> .419). Postoperative increase in spherical aberration was lower in SMILE than in LASIK (0.08 ± 0.16 vs 0.17 ± 0.18 µm,
P
= .002). The FOZ area was significantly larger in SMILE than in LASIK (30.25 ± 3.60 vs 29.21 ± 3.72 mm
2
), despite the smaller programmed OZ diameter (6.48 ± 0.08 vs 6.52 ± 0.11 mm) and smaller programmed treatment area (33.87 ± 0.81 vs 46.30 ± 2.61 mm
2
,
P
< .037). Pupil centration (0.43 ± 0.21 vs 0.41 ± 0.22 mm) and apex centration (0.48 ± 0.24 vs 0.48 ± 0.22 mm) were comparable between SMILE and LASIK (
P
> .694).

CONCLUSIONS:
SMILE created a larger FOZ than LASIK, despite the smaller programmed OZ. This may be due to a difference in the biomechanical response between the two procedures. Visual outcome and centration were comparable between SMILE and LASIK.

Plant vascular system-feeding Psyllidae (Hemiptera) and Nematoda genomes encode family 12 glycosyl hydrolases
Authors: Jones Richard W. 
Published: April 2019

AbstractInsect-encoded cellulolytic plant cell wall hydrolases have thus far been found mostly from glycosyl hydrolase family 5, 9, 10, and 45. We now report the first evidence for genomic encoding of family 12 glycosyl hydrolases in vascular feeding Psyllidae (Hemiptera) and Nematoda. The genes were identified in three psyllids (Acanthocasuarina muellerianaeTaylor,Pachypsylla venusta(Osten-Sacken), andDiaphorina citriKuwayama) and a root tip feeding dagger nematode (Xiphinema indexThorne and Allen; Dorylaimida: Longidoridae). While the final gene products were highly similar, the genomic intron structure varied, having a 2 kB intron inP. venusta, a 283 base-pair intron inD. citri, and no intron inX. index. Endoglucanase activity was demonstrated using theD. citrigenes in anAgrobacteriumConn (Rhizobiaceae) infiltration-based plant expression system. The presence of family 12 endoglucanases in this set of insects suggests a specific role in facilitating feeding on vascular tissue.
