The AAA to MC dose calculation as the impact of air-gap thickness and field size varied from 1.57% to 5.35% after the gap. Besides, patient's skin and oral cavity on head and neck case received a large dose discrepancy according to this study.
The dose air to tissue-equivalent ratio decreased with smaller air gaps and larger field sizes. Dose correction for AAA calculation of open small field size should be considered after small air-gaps. However, delivered beam from others gantry angle reduced this effect on clinical case.

Head and neck cancers are currently the most common types of cancers. 3D-conformal radiation therapy is the most common dose delivery technique for head and neck cancers. Eye Lens is a radio sensitive structure and cataract formation as a visual disorder associated with exposure to ionizing radiation which is documented.
Determining the radiation dose to eye lens during head and neck radiography and estimating the probability of cataract induction are essential.
This experimental study was performed on 14 patients with head and neck cancers through experimental study analysis. The maximum opacity of the eyes lens were measured by pentacam
before radiation therapy. CT data of patients were transmitted to Isogray treatment planning Software, and dose calculations for each patient was performed. At the end of radiation treatment, 3 and 6 months after radiotherapy, the eye lens opacity of the patients was assessed.
Overall, 28 lenses were studied. find more Statistical one sample K- S test proved normality of obtained data. Using repeated measures test, the relation before and 3 months after radiotherapy, as well as the relationship before and 6 months after radiotherapy proved a significant relationship.
The opacity caused by radiation in eyes is a non-statistical and linear-quadratic response curve with no threshold. This opacity can also appear within 3 months after completion of radiation therapy.

Radiotherapy has become a part of therapeutic process of more than 50 percent of patients suffering from cancer. However, recent studies have shown that radiation therapy might affect the expression of adhesive molecule related genes such as E-cadherin and cause cancer cells to move and migrate. Besides, various studies have reported that the expression of E-cadherin changes differently after radiation treatment. There are several studies which showed the loss of E-cadherin function after radiation; however, this reduction has not been observed in others.
This study aims to investigate the effect of different radiation doses of X-ray on changes that might occur in the expression of E-cadherin gene in colorectal cancer cell line HT-29.
In this experimental study, the cells cultured in flasks were irradiated with X- rays in different doses, including 0.1, 2.5, 5, and 10 Gy; then, the expression of E-cadherin gene was measured using real-time PCR.
The expression of E-cadherin did not change significantlyg to regulation of E-cadherin in HT-29 cell line.
Sexuality is a major facet of development during adolescence. Apace with normal sexual development, sexual experiences become more common and intimate. Recent research reports mixed results as to whether this is the case among transgender identifying adolescents. Recent research also suggests that trans youth experience negative sexual experiences (such as dating violence and sexual harassment) more often than their cisgender identifying peers. However, most studies have had clinical or selected samples.
The aim of this study is to compare the normative as well as negative sexual experiences of trans youth with their cisgender peers in the general population.
Our study included 1386 pupils of the ninth year of comprehensive school in Finland, mean age (SD) 15.59 (0.41) years. We compared sexual experiences, sexual harassment and dating violence among trans youth and their cisgender identifying peers. Distributions of the outcome variables were calculated among the whole sample and by sex. Next, multivars may in fact relate more closely to depression, a prevalent phenomenon among trans youth, than transgender identity itself.
Transgender identifying adolescents presented neither with delayed nor with excessively advanced sexual experiences. However, transgender youth seem to be more susceptible to subjection to sexual coercion and, unexpectedly, dating violence perpetration than their cisgender peers. However, these associations may in fact relate more closely to depression, a prevalent phenomenon among trans youth, than transgender identity itself.
Little is known about the scope of problems driving referrals to child and adolescent psychiatry services. Identifying the full range of mental disorders affecting a particular child can help triage the child to a clinician with the appropriate level of expertise. The Child Behavior Checklist (CBCL) is an easy-to-use assessment tool that may provide invaluable information regarding the severity of the presenting complaints and also aid in the referral process.
To assess the utility of the CBCL to gain insights into the type of clinical problems driving referrals of youth to an outpatient pediatric psychiatry clinic.
The sample consisted of 418 newly referred youth 4-18 years of age of both sexes. Parents completed the CBCL assessing psychopathology and competence. Rates of patients with elevated T-scores on each scale were calculated for the whole group and stratified by sex and age (≤12 versus >12).
The CBCL identified high rates of psychopathology affecting referred youth. It also provided inform mental health services by providing specific information about the presence and the severity of specific suspected disorder. These findings have implications for prioritizing scarce resources in child mental health and for improved consideration of the complexity of clinical presentations to pediatric psychiatry programs of any type.
