In 12 cows, transvaginal interstitial laser treatment (TILT) of the ovaries was performed using a neodynium:yttrium aluminium-garnet laser to investigate the feasibility of a new treatment approach for clomiphene-resistant patients with chronic hyperandrogenic anovulation. Powers of 1 and 2 W during 5 min of exposure were used. Sonographic changes of thermal damage during TILT, the extent and h...

Background: Cowper's syringocele is a rare condition, uncommon in the adult population. It is more common in the pediatric population. Patients could be asymptomatic or present with irritative and/or obstructive symptoms. Ultrasonography (US) of perineal region, pelvis MRI, or urethrography are the most often used diagnostic modalities. Surgical treatment is indicated in all symptomatic patient...

We investigated the use of Ga-68-DOTA-Tyr3-octreotate (Ga-68-DOTA-TATE) positron emission tomography (PET) and standardized uptake values (SUVs) to predict the effectiveness of treatment with the somatostatin analogue octreotide acetate (Sandostatin LAR) in patients with neuroendocrine tumors (NETs). Thirty patients with well-differentiated NETs of the ileum (grades G1 and G2) were studied with...

We investigated the effect of chronic administration of morphine on noxious stimulus-induced antinociception (NSIA) produced by intraplantar capsaicin injection. In the untreated (naive) rat, we previously found that NSIA depends on activation of dopamine, nicotinic acetylcholine, and mu- and delta-opioid receptors in nucleus accumbens. Rats chronically implanted with subcutaneous morphine pell...

Inhibition of mTOR is commonly considered a valid target in cancer treatment, but this assertion does not address effects on the immune microenvironment that may be detrimental to cancer treatment. Here we show how administration of the mTOR inhibitor RAD001 (everolimus) results in the occurrence of distant metastasis in a rat model of pancreatic cancer. RAD001 was administered twice weekly for...

Objective(s): Studies have indicated advantageous properties of [DOTA-DPhe1 , Tyr3 ] octreotide (DOTATOC) in tumor models and labeling with gallium. Breast cancer is the second leading cause of cancer mortality in women, and most of these cancers are often an adenocarcinoma. Due to the importance of target to non-target ratios in the efficacy of diagnosis, the pharmacokinetic of 68Ga-DOTATOC in...

CONTEXT Inherited and sporadic medullary thyroid cancer (MTC) is an uncommon and medically challenging malignancy. Even if the extent of initial surgery is deemed adequate, the recurrence rate remains high, up to 50% in most series. Measurement of serum calcitonin is important in the follow-up of patients with MTC, and reliably reflects the existence of the disease. EVIDENCE ACQUISITION There...

INTRODUCTION Paragangliomas (PGLs) related to hereditary syndromes are rare mediastinal tumors. Paragangliomas are caused by mutations in genes encoding subunits of succinate dehydrogenase enzyme (SDH). AIM To evaluate clinical, anatomical and functional characteristics of mediastinal paragangliomas related to SDHx gene mutations. MATERIAL AND METHODS Retrospective analysis of 75 patients w...

The serine protease CD26/dipeptidyl-peptidase IV (CD26/DPP IV) and chemokines are known key players in immunological processes. Surprisingly, CD26/DPP IV not only removed the expected Gly1-Pro2 dipeptide from the NH2 terminus of macrophage-derived chemokine (MDC) but subsequently also the Tyr3-Gly4 dipeptide, generating MDC(5-69). This second cleavage after a Gly residue demonstrated that the s...
