Arthroscopic Humeroplasty in the Treatment of Acute Reverse Hill-Sachs Lesion Associated With Posterior Shoulder Instability.

Reverse Hill-Sachs lesions (RHSL) are common complications associated with posterior shoulder dislocations and represent a significant challenge for preserving joint stability and function. If untreated, these compression fractures of the anteromedial humeral head can compromise the integrity of the joint, predisposing patients to recurrent instability and arthropathy. While various treatment modalities exist, achieving an anatomic reduction of the defect while preserving the articular cartilage remains a desirable outcome, particularly in acute settings.

Meningioma in the fourth ventricle in 2 cats.

Feline meningiomas typically arise on the surface of the brain but can occur in the third ventricle. Meningiomas in the fourth ventricle have not been reported in cats, to our knowledge. Here, we describe the clinical and pathologic findings of meningioma in the fourth ventricle in 2 cats.

Hemosporidian infection in free-living Cathartes aura (Linnaeus, 1758) in the Amazon biome, Pará State, Brazil: Parasitological, molecular, hematological, and biochemical analyses.

Hemosporidians are intracellular pathogens that infect a range of endothermic and ectothermic hosts and are transmitted by dipteran vectors. These parasites are grouped into four families: Haemoproteidae, Plasmodiidae, Leucocytozoidae, and Garniidae, with the genera Haemoproteus, Plasmodium, and Leucocytozoon being the most common in birds. Therefore, the objectives of this study were to detect the infection frequency of hemosporidians and to perform hematological and biochemical analyses in free-living turkey vultures (Cathartes aura) in the Amazon biome, Brazil.

Buthionine sulfoximine acts synergistically with doxorubicin as a sensitizer molecule on different tumor cell lines.

The chemotherapeutic drug doxorubicin (DOX) has been widely used for treating solid tumors attributed to its antiproliferative effectiveness; however, its clinical use is limited due to side effects, including cardiotoxicity, myelosuppression, and drug resistance. Combining DOX with buthionine sulfoximine (BSO), a glutathione (GSH) synthesis inhibitor, showed promising results in overcoming these adverse effects, potentially reducing the required DOX dose while maintaining efficacy. The aim of the present study was to examine the effects of different concentrations of BSO and DOX, both individually and in combination, utilizing B16/F10 (murine melanoma), SNB-19 (human glioblastoma), S180 (murine sarcoma), and SVEC4-10 (murine endothelial) cell lines.

Essential oil and aqueous extract of basil (Ocimum basilicum) in the diet of pacu (Piaractus mesopotamicus).

This study aimed to evaluate the effects of Ocimum basilicum supplementation in the diet for Piaractus mesopotamicus regarding productive performance, intestinal morphology, muscle residue, and hematological changes after simulated transport stress. Juvenile (23 g±0.08, n = 180) were stocked into 300-L tanks in three treatments and six replicates each: a control diet (not supplemented), a diet with 0.
