Dysregulation of Lipid and Glucose Homeostasis in Hepatocyte-Specific SLC25A34 Knockout Mice.

Nonalcoholic fatty liver disease (NAFLD) is an epidemic affecting 30% of the US population. It is characterized by insulin resistance, and by defective lipid metabolism and mitochondrial dysfunction in the liver. SLC25A34 is a major repressive target of miR-122, a miR that has a central role in NAFLD and liver cancer.

Preferential activation of the epidermal growth factor receptor in human colon carcinoma liver metastases in nude mice.

Increased epidermal growth factor receptor (EGF-R) gene expression and functional protein levels correlate with the metastatic potential of human colon carcinoma (HCC) cells in nude mice. The purpose of this study was to determine whether the production of liver metastases by HCC cells depends on the EGF-R activation status and whether different organ microenvironments influence this activation. Using two independent monoclonal antibodies specific for the activated (i.

Use of aromatase inhibitors in postmenopausal women with advanced breast cancer.

Surgeons have been involved in the management of metastatic breast cancer since the technique of ovarian ablation was introduced in 1896. However, as newer hormonal and chemotherapeutic regimens were developed, drug therapy gradually replaced surgery as the preferred treatment for metastatic breast cancer. Thus, management of metastatic breast cancer has largely shifted from surgeons to medical oncologists.

Annexin II marks astrocytic brain tumors of high histologic grade.

Annexin II is highly expressed in glioblastoma multiforme [Reeves, S. A.; Chavez-Kappel, C.

Genitourinary malformations associated with agenesis of the corpus callosum.

Agenesis of the corpus callosum is an infrequent congenital anomaly that occurs in partial or complete forms, and is frequently associated with other craniofacial and skeletal abnormalities. An increased association with genitourinary abnormalities has not been previously defined. We reviewed the records of 22 boys and 11 girls with agenesis of the corpus callosum.

Affinity isolation of transcriptionally active DNA.

Chicken erythrocyte nuclei were nick translated with the chemically cleavable biotinylated nucleotide, Bio-12-SS-dUTP. DNA was purified, digested with restriction endonucleases, and applied to an avidin-agarose affinity column. Seventy percent of the nick translated DNA bound to the column.

Disseminated intravascular coagulation: a review.

Disseminated intravascular coagulation (DIC) results from activation of the blood coagulation cascade by various disease processes. DIC may occur with blunt head trauma and, with severe head trauma, may reflect brain parenchymal injury. Oral and maxillofacial surgeons who treat traumatized patients should be aware of the implications of DIC with regard to patient management, diagnosis, and surgical considerations.

Massive tongue necrosis secondary to temporal arteritis.

A case of unusually massive necrosis of the tongue secondary to temporal arteritis is presented. The clinician must include temporal arteritis in the differential diagnosis of patients presenting with signs and symptoms of tongue ischemia.

Diaphragm pacing in spinal muscular atrophy: case report.

A patient with a diagnosis of intermediate or benign spinal muscular atrophy was severely incapacitated from respiratory complications and alveolar hypoventilation and was confined to mechanical ventilatory support. After extensive diagnostic evaluation of her pulmonary status, including transcutaneous stimulation of the phrenic nerves associated with nasogastric and surface electrode recording of the diaphragmatic response, this patient had a phrenic neurostimulation system implanted bilaterally for diaphragm pacing. Although spinal muscular atrophy has not been previously recognized as an indication for diaphragm pacing, her subsequent social, physical, and psychological improvement indicate that it may be significantly beneficial in selected cases of alveolar hypoventilation due to spinal muscular atrophy or neuromuscular disease.
