Hepatic myxosarcoma in a domestic shorthair cat.

Myxosarcomas are rare malignant neoplasms of soft connective tissues, and there are no reports of hepatic myxosarcomas in cats. An eight-year-old male, neutered, domestic shorthair cat presented with progressive hyporexia, lethargy, and weight loss. An ultrasonography study showed a large abdominal mass connected to the liver.

Diffuse Uterine Adenomyosis and Bilateral Ovarian Cysts in a Chinchilla Cat.

A 10-year-old female intact chinchilla cat was presented with intermittent vomiting and mild lethargy over the previous few months. Clinical signs and laboratory tests were unremarkable. Following an elective ovariohysterectomy, bilateral ovarian cysts and uterine adenomyosis were diagnosed in the patient.

The burden of pure anisometropic amblyopia: a cross-sectional study on 2800 Iranians.

Purpose: To assess the proportion of pure anisometropic amblyopia in a sample Iranian (white) population.

Methods: A total of 2800 consecutive individuals who presented at a referral eye clinic for any reason were examined for the presence of pure anisometropic amblyopia. Anisometropia was reported when a spherical equivalent refraction difference of at least 1.

Click Chemistry in Lead Optimization of Boronic Acids as β-Lactamase Inhibitors.

Boronic acid transition-state inhibitors (BATSIs) represent one of the most promising classes of β-lactamase inhibitors. Here we describe a new class of BATSIs, namely, 1-amido-2-triazolylethaneboronic acids, which were synthesized by combining the asymmetric homologation of boronates with copper-catalyzed azide-alkyne cycloaddition for the stereoselective insertion of the amido group and the regioselective formation of the 1,4-disubstituted triazole, respectively. This synthetic pathway, which avoids intermediate purifications, proved to be flexible and efficient, affording in good yields a panel of 14 BATSIs bearing three different R1 amide side chains (acetamido, benzylamido, and 2-thienylacetamido) and several R substituents on the triazole.

Quality of sunglasses available in the Iranian market; a study with emphasis on sellers' license.

Context: Sunglasses should follow minimum requirements to sufficiently protect eyes. It is not known whether all items obtainable from the market are appropriately designed.

Aims: To compare ultraviolet (UV)-protective properties of commercially available sunglasses obtained from authorized and unauthorized Iranian sellers.
