Authors: Dalaman Zeynep Banu , Kayalak Hasan
Published: August 2024

This study delves into an extensive exploration of migration and securitization policies within the context of Türkiye, with a specific focus on Afghan irregular migration and the function of repatriation centers. The research scrutinizes state policies that initiate the migration process of Afghan irregular migrants to Türkiye, deficiencies in border security, and related practices. The influence of key global events such as the Taliban’s takeover, the withdrawal of US and NATO forces, and the ensuing political turmoil in Afghanistan are examined as triggers for migration. These factors, coupled with issues such as personal safety, unemployment, and poverty, have led to increased internal and external migration. The study also investigates the myriad challenges Türkiye faces in dealing with the surge of migrants. Housing, health, education, integration, employment, social services, urbanization, and various public policy areas are all areas strained by this influx. Attention is given to the Return Centers under the Directorate General of Migration Management, where irregular migrants are gathered with the aim of repatriation to their home countries. The study explores the incidents, causes, consequences, and security issues encountered during this process. As part of the research, interviews were conducted with Afghan migrants who were willing to participate. These interviews provided insights into their experiences before migration, during their journey, and after arriving in Türkiye. The interviews shed light on the experiences of migrants, including the struggles they face, their reasons for migration, and the impact of their journey on their lives. Additionally, the study delves into the role of the Tuzla Repatriation Center, located in Istanbul’s Tuzla district and operated by the Provincial Directorate of Migration Management. Despite the confidential nature and ever-changing data at the center, the research attempts to provide a comprehensive understanding of its operations and the experiences of the migrants housed there. The findings of this study are significant in understanding the complexities of migration, the role of repatriation centers, and the effects of state policies on the lives and experiences of migrants. The research provides valuable insights into the challenges and potential policy implications of managing migration and offers potential pathways for addressing these issues effectively.

VALIDATED HPLC METHOD TO ANALYZE PHYTOCHEMICAL STRUCTURE OF SCORZONERA SPECIES GROWN IN TÜRKİYE
Authors: Ercan Seda , Kurtul Ekin , Yilmaz Özge , Bahadır Acıkara Özlem
Published: August 2024

Objective: The current study evaluated Scorzonera L. (Asteraceae) species, which are used as vegetables and medicinal plants in different countries where they grow naturally, such as Türkiye, Europe, Mongolia, and China, for their phenolic composition.
Material and Method: The twenty-five members of the Scorzonera genus, collected from different parts of Turkey, were investigated using a newly developed and validated High-Performance Liquid Chromatography (HPLC) method using some standard compounds, including chlorogenic acid, hyperoside, isoorientin, orientin, 7-O-methyl-isoorientin, isoquercetin, luteolin-7-O-β-glycoside, rutin, swertisin, and vitexin. The limit of detection and quantification levels were determined for each standard compound.
Result and Discussion: This study has revealed that the aerial parts are rich in phenolic compounds, with significantly higher amounts than the roots. Chlorogenic acid was detected in aerial parts and roots of all tested species and Scorzonera kotschyi aerial parts contained the highest amount (1787.26±32.88 µg/g). Most of the tested species contained varying amounts of hyperoside, isoorientin, isoquercetin, and orientin. Scorzonera aucheriana (572.93±0.04 µg/g), Scorzonera laciniata ssp. laciniata (524.07±5.06 µg/g), Scorzonera tomentosa (892.00±4.58 µg/g) and Scorzonera cana var. jacquiniana (309.23±1.69 µg/g) aerial parts contain these compounds respectively in higher amount. In contrast, vitexin, rutin and luteolin-7-O-β-glycoside were detected in a relatively small number of the tested species.

On strangleholds and tipping points
Authors:   , Houben Rosa Maria Allegonda Catharina
Published: August 2024

The infectious agents Streptococcus equi subspecies equi (S. equi, the cause of strangles) and EHV-1 (a cause of mild cold-like symptoms, but also of abortion and neurological disease) occur frequently in horses in the Netherlands, as in most of the rest of the world. Research into the best control strategies for these diseases does not currently include (mathematical) models of transmission. This thesis contains several building blocks which will help apply such models to the control effort of these diseases.
The basic reproduction number (R0) for S. equi was estimated from real-world outbreaks, and for EHV-1, we attempted to demonstrate an effect of herd vaccination on transmission potential of the virus, but were unable to show a significant effect. By comparing model outputs to real-world epidemiological data on S. equi, we were able to demonstrate that a long-held belief that one in four horses do not mount lasting immunity after strangles may be incorrect.
We surveyed apparently healthy horses and ponies from throughout the Netherlands and found that around 1 in 26 of these were strangles carriers. Combining this information with 2022 competition records and disease surveillance reports, simulations showed that carriers and susceptible horses very frequently meet at competitions (hundreds of thousands of times per year), but that very few of these contacts lead to infection and disease in the susceptible horses.
A questionnaire survey revealed that very few equine premises in the Netherlands implement effective bio-security measures, which is similar to reports from other countries. Approximately 4/5 of surveyed premises reported horses temporarily leaving the premises to participate in competitions or for training.
Network analysis using sports and racing competition records revealed that the “social network” of sport horses and of racehorses are each highly connected. The Dutch sport horse network has five degrees of separation, meaning there is a connection between any two horses (that participate in sports competitions) of no more than five steps of horses that have attended the same competitive event at some time during the year.
Horses are group housed like livestock, but travel and socialise like humans. Therefore, the control of equine infectious diseases poses challenges unique to the species. The information gathered in this thesis can be carried forward into data–driven models to evaluate the most (cost-)efficient control strategies for EHV-1 and S. equi.
Non-Scarring Alopecia in Females: A Comprehensive Review
Authors: Aristizabal Miguel A. , Bruce Alison J. , Rogers III Roy S. , Pincelli Thais
Published: August 2024

Alopecia is prevalent among females, categorised as either scarring or non-scarring, depending on the potential for hair follicle regeneration. Various aetiologic factors are implicated in non-scarring alopecia, including genetic predisposition, loss of immune privilege, oxidative damage, and hormonal fluctuations. Telogen effluvium, alopecia areata, and female pattern hair loss are the main causes of non-scarring alopecia in females of all ages. This review covers the aetiology, pathophysiology, and treatment of the most common non-scarring alopecias in females.
Getting the Sack: The Controversial Late 1950s Fashion
Authors: Lazaro David E.
Published: August 2024

This article analyses the 1950s sack dress within the context of American and English fashion. The garment, featuring an undefined waistline and a shorter, more constricted hemline, was by all accounts as popular (and controversial) as the changes in women’s fashion in the years after the Second World War. While the sack’s zenith can be clocked to the autumn of 1957 and spring of 1958, this article contextualizes this moment against the trajectory of less figure-defining fashions throughout the 1950s. The uproar against the style has become legendary, centred around expectations of how a woman (and her figure) was supposed to appear in clothes, and the attendant discipline suggested by and required for that appearance. To term the style a failure, which later reminisces have repeatedly done, glosses over both the sack’s popularity at the time, as well as its legacy as a harbinger for more youth-centred fashions in the 1960s. Through an understanding of the precedents, timeline, manifestations and press reactions to the garment, including a material culture analysis, this article contextualizes the sack’s moment in dress history and its contribution to twentieth-century fashion.

Published: August 2024

Kutil anogenital (KAG) merupakan salah satu infeksi menular seksual berupa lesi proliferatif jinak yang disebabkan oleh Human papillomavirus (HPV). Karsinoma sel skuamosa (KSS) ad regio anogenital sering menjadi diagnosis banding dari KAG. Krim podofiloks menjadi salah satu terapi pilihan untuk pengobatan KAG. Dilaporkan satu kasus KAG ad regio penis dan perianal pada pasien Human Immunodeficiency Virus (HIV), seorang laki-laki berusia 31 tahun. Pada pemeriksaan fisis ditemukan lesi papul sewarna kulit dengan permukaan papilomatosa dan verukosa pada penis dan perianal. Pemeriksaan penunjang acetowhitedidapatkan hasil positif. Gambaran histopatologis menunjukkan gambaran hiperplastis, hiperkeratosis, akantosis, dan papilomatosa. Berdasarkan hasil polymerase chain reaction (PCR) HPV tipe 6, 11, 16, dan 18 didapatkan hasil negatif. Pasien mendapatkan terapi krim podofiloks 0,5% selama tiga siklus dengan hasil yang signifikan. Diagnosis KAG ditegakkan berdasarkan anamnesis, pemeriksaan fisis, histopatologis, dan PCR. Sampai saat ini belum ada terapi yang ideal dan spesifik untuk pengobatan KAG. Podofiloks merupakan salah satu pilihan pengobatan topikal yang diaplikasikan sendiri oleh pasien dua kali sehari selama tiga hari diikuti dengan empat hari tanpa terapi diulang sebanyak empat siklus. Diperlukan pemeriksaan yang komprehensif untuk dapat menegakkan KAG dan menyingkirkan diagnosis banding dengan KSS. Terapi podofiloks dapat menjadi pilihan yang dapat dipertimbangkan untuk terapi pada KAG.

ABSTRAK
Rosasea merupakan suatu kondisi inflamasi kronis pada kulit bersifat kambuhan yang mengenai daerah sentrofasial (hidung, dagu, pipi, dahi dan glabela). Secara klinis, rosasea ditandai oleh adanya eritema (transien hingga persisten), telangiektasis, papul, pustul dan perubahan fimatosa. Tanda klinis tersebut disertai rasa gatal, terbakar, tersengat atau nyeri.Â Di RSUP Sanglah Denpasar sejak Januari 2019 sampai Desember 2021 tercatat sebanyak 5 kasus rosasea dengan tipe papulopustular.
Laki-laki, usia 49 tahun, suku Jawa,Â Warga Negara Indonesia, munculÂ kemerahan pada kedua pipi, dagu, hidung dan dahi disertai benjolan kecil seperti jerawat berwarna kemerahan dan sebagian berisi nanah disertai rasa nyeri seperti terbakar dan gatal sejak 2 tahun yang lalu. Riwayat sering terpajan sinar matahari.Â Pasien mengaku gemar makan makanan pedas, berkuah panas seperti sup atau soto, serta meminum kopi panas setiap pagi.Â Diagnosis rosasea ditegakkan berdasarkan anamnesis, gejala klinis, pemeriksaan dermoskopi dan histopatologi. Tatalaksana berupaÂ doksisiklin 100 mg tiap 12 jam intra oral, asam azaleat 20% gel topikal tiap 24 jam (pagi hari), tabir surya topikal denganÂ Sun Protector FactorÂ (SPF) 45, tretinoin 0,025% krim topikal tiap 24 jamÂ memberikan perbaikan klinis pada minggu ketujuh.Â Terapi yang tepat dan menghindari faktor pencetus umumnya dapat mengurangi kekambuhan rosasea.

Reverse time migration based on the body-fitted grid in pseudo-acoustic vertical transverse isotropic media with non-flat surface topography

Published: August 2024

As one of the main seismic imaging methods, conventional reverse time migration (RTM) may not produce high-quality images in areas with non-flat surfaces and anisotropy because the complex surfaces have a great impact on seismic wave simulation, resulting in strong scattering waves. In addition, in isotropic acoustic (ISO) RTM, the neglection of the anisotropic effects will lead to incorrect travel times during source and receiver wavefield extrapolation. To overcome these problems, we develop a topographic pseudo-acoustic vertical transverse isotropic (VTI) RTM algorithm based on the body-fitted grid. In this method, we first derive anisotropic pseudo-acoustic wave equations in the curvilinear coordinate system. Then, the Lebedev grid finite-difference scheme is used to update these equations to simulate wavefields. Finally, we use the source-normalized cross-correlation imaging condition to realize RTM. Numerical tests are performed to evaluate the feasibility and applicability of the proposed method. The imaging results show that the proposed method can remove the effect of surface topography and anisotropy on seismic wave propagation and improve migration imaging precision.
Nutritional profiling of five New Zealand seaweeds – a preliminary assessment
Authors: Battershill Zoe V.
Published: August 2024

This study set out to provide a preliminary assessment of nutritional profiles of five selected New Zealand macroalgae to investigate the potential of land-cultivated Ulva spp. The New Zealand seaweeds species, selected from a limited range, were either collected from the wild (Pyropia plicata from Tauranga and Kaikōura), or were sourced from commercial wild harvest suppliers (Macrocystis pyrifera and Undaria pinnatifida), and were compared to land-based cultivated Ulva species (Ulva ralfsii and Ulva stenophylloides). Species were assessed for their content of crude protein, total lipids, carbohydrates, fibers, amino acids, mineral profiles, heavy metals and antioxidant capacity (Oxygen Radical Absorbance Capacity, ORAC). The two cultivated Ulva spp. had the highest crude protein content of the six seaweeds analyzed (approximately 21% dw, N×6.25), as expected with nutrient supplemented cultivation. They also had the highest total, essential and branched chain amino acid quantities (151, 70, and 29 mg/g for U. stenophylloides and 138, 62, and 27 mg/g for U. ralfsii). Though the two Ulva spp. were grown to the same cultivation specifications, they varied in carbohydrate and total fiber content (U. stenophylloides: 63% and 62%; U. ralfsii: 39% and 40%, respectively). Pyropia plicata collected in Kaikōura had the highest carbohydrate levels (65%) though not the highest total fiber. Both P. plicata had the highest trace minerals (417 mg/kg and 720 mg/kg for Kaikōura and Tauranga P. plicata respectively). All seaweeds analyzed showed no lipophilic antioxidants, though the two Phaeophyceae had the highest hydrophilic antioxidant content at 115 TE and 168 TE for Macrocystis pyrifera and Undaria pinnatifida, respectively. This paper provides a preliminary indication of the relative nutritional attributes of a range of potential New Zealand seaweed aquaculture targets benchmarked against sea-lettuce (Ulva spp.).
