Relations among lie-telling self-efficacy, moral disengagement, and willingness to tell antisocial lies among children and adolescents.

This study examined a proposed model of relations among lie-telling self-efficacy, moral disengagement, and willingness to tell antisocial lies among children and adolescents. Children and adolescents aged 6 to 15 years completed measures of lie-telling self-efficacy and moral disengagement. They also read vignettes about a character committing a transgression and telling a lie to conceal the transgression.

A cross-cultural comparison of the relation between children's moral standards of honesty and their lie-telling behavior.

This study examined the relation between children's moral standards of honesty and their lie-telling behavior and the role that culture plays in this relation. In the study, 6- to 12-year-old Chinese and Northern American (Canadian and American) children underwent a behavioral paradigm where they had the opportunity to tell a lie about their performance to gain a benefit. The children then read vignettes where a character told lies to conceal a transgression committed to satisfy either a need or a desire and evaluated those lies.

Evaluating the accuracy of functional biomarkers for detecting histological changes in chronic allograft nephropathy.

The most common cause of late kidney transplant failure is chronic allograft nephropathy (CAN). Much research has focused on identifying biomarkers (or correlates) that would predict subsequent CAN and allow timely intervention. Functional biomarkers such as serum creatinine and estimated glomerular filtration rate (eGFR) have been widely adopted, even though they have not been rigorously evaluated as surrogate markers.

Expression of steroid receptors in intact rat uterus, mammary gland, and liver treated with selective estrogen receptor modulators and conjugated equine estrogens.

The aim of the present study was to determine the effects of conjugated equine estrogens (CEE) and selective estrogen receptor modulators (SERM) (tamoxifen [TAM] and raloxifene [RAL]) on the expression of steroid receptors-estrogen receptor (ER) and progesterone receptor (PR)-in intact rat uterus, mammary gland, and liver. A total of 24 female rats weighing 250 to 300 g were randomized into 4 groups. Groups 1, 2, 3, and 4 were respectively given conjugated equine estrogen, tamoxifen, raloxifene, and vehicle for a 28-day period.

Gastric heterotopia in the gallbladder: a case report.

A case of incidentally identified ectopic gastric mucosa in the gallbladder of a 26-year-old man with a three year history of recurrent abdominal pain is presented. The aberrant gastric tissue consisted of gastric pyloric glands and fundic glands. Focal intestinal metaplasia characterized by goblet cells containing sialomucin was seen in the surrounding gallbladder mucosa but no metaplastic change was seen in the heterotopic tissue.

Light and electron microscope examination of the effects of methotrexate on the endosalpinx.

Objective: To examine the effects of increasing doses of methotrexate (Mtx) on the fallopian tubes.

Study Design: The study was carried out on 24 female rats (Albino Wistar type, 250-300 g). The rats were randomly divided into four groups of six.

A childhood case of intrascrotal neurofibroma with a brief review of the literature.

Solitary neurofibroma unassociated with neurofibromatosis type I (NFI) arising within the scrotum is an extremely rare benign tumor. There are 8 cases reported in the literature with only 1 that occurred in childhood. In the current report the authors describe an additional adolescent patient, the second case encountered in childhood and the ninth case reported in the literature, together with a review of the related articles.

The fate of hydroxyapatite cement used for cranial contouring: histological evaluation of a case.

Craniofacial contouring is a commonly performed procedure applied for traumatic and postsurgical cranial vault or facial skeleton irregularities. Hydroxyapatite cement is an alloplastic material composed of tetracalcium phospate and dicalcium phospate anhydrous that transforms into a paste-like substance when these two compounds placed in an aqueous environment. This mixture, which is a nonceramic microporous calcium phosphate combination, is another alternative for refining the craniofacial contour.

Reconstruction of orbital floor fracture using solvent-preserved bone graft.

The orbital floor is one of the most frequently damaged parts of the maxillofacial skeleton during facial trauma. Unfavorable aesthetic and functional outcomes are frequent when it is treated inadequately. The treatment consists of spanning the floor defect with a material that can provide structural support and restore the orbital volume.

Atypical presentation of pilomatricoma: a case report.

Background: Malherbe tumors, also known as pilomatricomas, are benign cutaneous tumors of hair matrix origin.

Objective: To discuss a rare case of multiple pilomatricoma of the head and neck region in a very young patient.

Methods: A 14-month-old baby presented with two lesions, one appearing on the preauricular region and the other on the nasolabial fold.
