The astrocytic zinc transporter ZIP12 is a synaptic protein that contributes to synaptic zinc levels in mouse auditory cortex.

Synaptically released zinc is a neuronal signaling system that arises from the actions of the presynaptic vesicular zinc transporter protein ZnT3. Mechanisms that regulate the actions of zinc at synapses are of great importance for many aspects of synaptic signaling in the brain. Here, we identify the astrocytic zinc transporter protein ZIP12 as a candidate mechanism that contributes to zinc clearance at cortical synapses.

Evaluation of fruquintinib's efficacy and safety in refractory metastatic colorectal cancer: a systematic review and meta-analysis of phase II and III randomized controlled trials.

Background: Metastatic colorectal cancer (mCRC) remains a significant cause of mortality despite advancements in treatments. Fruquintinib, a potent VEGFR inhibitor, has shown promise as an advanced therapy for mCRC. This review evaluates the efficacy and safety of fruquintinib compared to placebo in patients with refractory mCRC, focusing on Phase II and III trials.

Pre-Prediabetes: Insulin Resistance is Associated with Cardiometabolic Risk in Non-obese Patients (STOP DIABETES).

Background/aim: To examine if insulin resistance is associated with markers of glycemic, cardiometabolic and atherosclerotic risk in non-obese, non-prediabetic individuals compared to insulin sensitive subjects matched for BMI, gender, and age.

Methods: Of 1860 patients from STOP DIABETES study, 624 had normal fasting plasma glucose, body mass index < 30, and HbA1c < 5.7%.

Equine intervertebral disc disease with dorsal protrusion and spinal cord compression: A computed tomography, myelography, MRI, and histopathologic case study.

A 3-year-old American Saddlebred gelding presented for progressive tetraparesis, ataxia, and cervical hyperaesthesia. Radiographic myelography identified spinal cord compression at C6-7 in neutral, extended, and flexed positions and at C4-5 in the flexed position. CT myelography and postmortem MRI identified severe vertebral canal stenosis/compression at C6-7.

Infectious Causes of Equine Placentitis and Abortion.

A variety of infectious agents including viral, bacterial, and fungal organisms can cause equine abortion and placentitis. Knowledge of normal anatomy and the common pattern distribution of different infectious agents will assist the practitioner in evaluating the fetus and/or placenta, collecting appropriate samples for further testing, and in some cases, forming a presumptive diagnosis. In all cases, it is recommended to confirm the diagnosis with molecular, serologic, or microbiological testing.
