Antibodies that reacted with plasma membranes of human eye muscle but showed no binding to plasma membranes of human skeletal muscle were identified in serum of patients with Graves' ophthalmopathy. Rabbit antithyroglobulin serum at a dilution of 1 X 10(-3) to 20 X 10(-3) had no effect on the binding of these antibodies to eye muscle membrane antigens. There was no correlation between antihuman eye muscle plasma membrane antibodies and antihuman thyroid membrane antibodies or antibodies against thyroglobulin. It is suggested that specific antibodies against eye muscle membranes are present in Graves' ophthalmopathy and that this disease might represent a distinct autoimmune disorder.

Purpose: To evaluate the efficacy and complications of simplified graded inferior oblique anterior transposition (IOAT) in treating at least 10 PD vertical deviation in the primary position and inferior oblique muscle overaction (IOOA).

Methods: This retrospective study reviewed the medical records of 65 patients treated with simplified graded IOAT procedures for both vertical deviation and IOOA. Patients were grouped according to vertical deviation in the primary position.

Peribulbar anesthesia is mainly used for cataract surgery. Many studies had used atracurium and rocuronium as an additive to the local anesthetic (LA) drugs in eye surgery. The aim of this study is to evaluate the efficacy of adding atracurium versus rocuronium to a local anesthetic mixture, in providing an early onset of orbital akinesia and corneal anesthesia during cataract surgery.

Performance of weighted genomic BLUP and Bayesian methods for Hanwoo carcass traits.

Trop Anim Health Prod

Department of Biotechnology, Yeungnam University, Gyeongsan, Gyeongbuk, 38541, Republic of Korea.

To improve the quality and yield of the Korean beef industry, selection criteria often focus on estimated breeding values for carcass weight (CWT), eye muscle area (EMA), backfat thickness (BF), and marbling score (MS). This study estimated genetic parameters and assessed the accuracy of genomic estimated breeding values (GEBVs) using SNP weighting methods. We compared the accuracy of these methods with the genomic best linear unbiased prediction (GBLUP) and various Bayesian approaches (BayesA, BayesB, BayesC, and BayesCPi) for the specified traits.

The contribution of sex hormones to cardiovascular disease, including arterial stiffness, is established; however, the role of sex chromosome interaction with sex hormones, particularly in women, is lagging. Arterial structural stiffness depends on the intrinsic properties and transmural wall geometry that comprise a network of cells and extracellular matrix (ECM) proteins expressed in a sex-dependent manner. In this study, we used four-core genotype (FCG) mice to determine the relative contribution of sex hormones versus sex chromosomes or their interaction with arterial structural stiffness.

Relationship between the and the gene copy number variation and growth traits in different cattle breeds.

Anim Biotechnol

December 2025

Jilin Academy of Agricultural Sciences, Changchun, Jilin Province, China.

Copy number variations (CNV) are important genetic variations. The endogenous factors cobalamin receptor () and MIA SH3 domain ER-derived factor 3 () are associated with bone/muscle development and intramuscular fat deposition. There have been no reports on the effects of and CNVs on growth traits of Chinese cattle.
