The aim of this study was to evaluate the immediate results of the stereotactic radiosurgery (SRS) application in patients with choroid melanoma.Material and methods. The prospective study included 43 patients who were diagnosed with choroidal melanoma cT1–3N0M0.SRS was performed on a Gamma Knife gamma therapeutic unit, Perfexion (Elekta, Sweden). Under local anesthesia, the eyeball was immobilized using frenulum sutures on the rectus muscles. The median prescribed dose per tumor margin at 50% isodose was 30 Gy. The immediate effect of the treatment was assessed as positive (local control) in all cases, except increased blood flow according to Doppler ultrasound, an increase in tumor size by more than 20% of the previously determined lesion according to MRI.Results. During the follow-up period (median follow-up — 16 months), there were no cases of negative outcome in terms of local tumor control.A statistically significant gradual decrease in tumor thickness was revealed during the entire observation period (6.6±2.1 mm before treatment, 5.3±2.1 mm 12 months after treatment, p<0.001), stabilization of the tumor base (12.25±3.26 mm before treatment, 11.4±2.5 mm 12 months after treatment, p=0.355). Contrast-enhanced MRI also showed a progressive statistically significant decrease in tumor volume (635.21±328.32 mm3 before treatment, 376.0±267.6 mm3 15 months after treatment, p><0.001). The eyeball was saved in 90.1%. Post-radiation optical retinopathy developed in 9.3% of >˂0.001), stabilization of the tumor base (12.25±3.26 mm before treatment, 11.4±2.5 mm 12 months after treatment, p=0.355). Contrast-enhanced MRI also showed a progressive statistically significant decrease in tumor volume (635.21±328.32 mm3 before treatment, 376.0±267.6 mm3 15 months after treatment, p<0.001). The eyeball was saved in 90.1%. Post-radiation optical retinopathy developed in 9.3% of>˂0.001). The eyeball was saved in 90.1%. Post-radiation optical retinopathy developed in 9.3% of cases, progression of retinal detachment was registered in 13.9% of cases. The one-year metastatic-free survival rate was 96.3±3.6%, the two-year survival rate was 81.3±8.6%.Conclusions. In the present study, the use of stereotactic radiosurgery with a prescribed marginal dose of up to 35 Gy allowed achieving sustainable local control of primary choroidal melanoma cT1–3 in 100% of cases over a median follow-up period of 16 months.

Fair Value Accounting for Property, Plant, and Equipment: Impact of IFRS 1 Adoption
Authors: Jin Yan , Niu Flora , Sheng Leo 
Published: May 2022

ABSTRACT
This paper uses a unique setting of Canadian public firms adopting International Financial Reporting Standards (IFRS) to investigate the factors that motivate companies to revalue Property, Plant, and Equipment (PP&E) under the deemed cost provision in IFRS 1, and whether revaluations help predict future performance, and what is the market reaction to such revaluations. Utilizing the probit model, difference-in-differences approach, and Wald test, we find that large firms and/or firms with higher net PP&E to total assets ratios are more likely to revalue PP&E, and firms adopting the fair value option for PP&E record lower depreciation in the post-IFRS period. In addition, we show that investors react negatively to the firms electing the fair value option for PP&E and the market discounts such revaluation information.
The Optional Qualitative Assessment in Impairment Tests
Authors: Black Dirk E. , Krupa Jake , Minutti-Meza Miguel 
Published: May 2022

ABSTRACT
International and U.S. accounting standards mandate a one-step quantitative impairment test for goodwill and other indefinite-lived intangibles, but U.S. standards allow an optional qualitative assessment before the quantitative test. This option is intended to reduce the complexity and costs of the quantitative test. We demonstrate that U.S. firms using this option have comparatively higher valuations and face higher expected costs for conducting quantitative tests. Using a difference-in-differences research design, we show that firms using this option have a marginally higher incidence of impairments, suggesting that the qualitative assessment does not systematically allow companies to avoid write-downs. Moreover, we do not find clear evidence that using this option decreases the timeliness of impairments or increases monitoring costs for auditors, regulators, and investors. Our study provides evidence about the consequences of a revised impairment approach and speaks to the broader issue of allowing unconditional options and qualitative judgments in financial reporting.

Published: May 2022

ABSTRACT

Objectives
To determine whether there is an association between skeletal jaw position and perioral musculature, and if genotypes can predict skeletal growth.

Materials and Methods
A prospective study on 42 patients over 1 year was performed. The study included 22 females and 20 males with and average age of 28.5 years. Lip strength was compared to radiographic cephalometric measurements. Allelic and genotypic frequencies from polymorphisms rs678397 and rs1815739 in ACTN3 and rs10850110 in MYO1H were compared to each variable. Chi–square and Fisher exact tests were used to determine if differences were statistically significant (alpha = 0.05).

Results
The data showed significant differences between rs678397 genotype and allele frequencies and SNA angle (P = .01; P = .003, respectively); between rs1815739 allele frequency and SNA angle (P = .01); between rs678397 allele frequency and ANB angle (P = .049); between rs678397 genotype and allele frequencies and lip strength in females (P = .045; P = .02); and between rs678397 allele frequency and overall lip strength (P = .049), after mean strength values used as cut off being customized by sex.

Conclusions
Polymorphisms in ACTN3 are associated with weak lips and larger SNA and ANB angles.

MYTHOLOGICAL SYMBOLS FROM THE THRACIAN MEGALITHIC SANCTUARIES, CHRISTIAN AND MUSLIM SACRED PLACES ON THE BALKANS
Authors: Markov Vassil 
Published: May 2022

The ancient Thracian megalithic and stone-hewn sacred places are full of symbols closely connected with the Thracian mythology and ancient cult practices which were typical for this area. Among them the most numerous are the huge stone-hewn human footprints, which in Bulgarian folklore were regarded as the footprints of the hero Krali Marko, who was thought of as the guardian of the people in Bulgaria. In the contemporary science studying Thrace he is believed to have been the folklore successor of the Thracian Dionysus.Marking the sacred place with a stone-hewn footstep altar of the hero was authentic evidence for the believers in ancient times that the god had been there in primordial mythological times. In this way, through the contact with the divine, the monumental rock turns into sacred and the place turns into a sanctuary. The raw becomes boiled, Nature becomes culture. With the establishment of Christianity as the sole religion in the Roman Empire since the 4th century, some of the Thracian megalithic sanctuaries have been abandoned. Others have been Christianized. Later, others in the Middle Ages were converted into Islamic sacred places. In this way they became permanently sacred places on the Balkans. Part of the signs-symbols in them have a new meaning in the spirit of the new religions.
