Wild-type and UCP2 knockout mice were used to
establish chronic mild stress (CMS)-induced anhedonia model of depression. The results showed that CMS led to more severe depressive responses in UCP2 knockout mice, characterized by exacerbated depression-like behaviors, increased corticosterone level and significant loss of weight. Moreover, CMS resulted in a higher mortality in UCP2 knockout mice. Our further study showed that UCP2 knockout enhanced CMS-induced activation of nuclear factor kappa B (NF-kappa B) p65 and increased mRNA expression of tumor necrosis factor alpha (TNF-alpha) in hypothalamus. And the levels of TNF-a of serum and spleen in UCP2 knockout mice are remarkably enhanced by CMS, even under basal conditions. Therefore, our findings suggest that UCP2 knockout-induced inflammation may contribute to the development of depressive symptoms. (C) 2011 IBRO. Published by Elsevier Ltd.

“Objective: Low-dose chest computed tomography (CT) is being evaluated in several national trials as a screening modality for the early detection of lung cancer. The goal of the present study was to determine whether lung cancer screening could be done while minimizing the number
of benign biopsy specimens taken in an area endemic for histoplasmosis.
Methods: The subjects were recruited by letters mailed to area physicians and local advertisement. The inclusion criteria were age older than 50 years and at least a 20 pack-year smoking history. Repotrectinib The exclusion criteria were symptoms suggestive of lung cancer or a history of malignancy in the previous 5 years. The participants completed a questionnaire and underwent a chest CT scan at baseline and annually for 5 years. The management of positive screening results was determined using a defined algorithm: annual follow-up CT scan for nodules less than 5 mm; 6-month follow-up CT scan for nodules 5 to 7 mm; review by our multidisciplinary tumor board for nodules 8 to 12 mm; and biopsy for nodules greater than 12 mm.
Results:
A total ACY-738 manufacturer of 132 patients were recruited. Of the 132 patients, 61% had positive baseline CT findings and 22% had positive findings on the annual CT scans. Six cancers were detected. Of these 6 patients, 5 had stage I disease and underwent lobectomy, and 1 had stage IIIA disease and underwent induction chemotherapy and radiotherapy followed by lobectomy. All patients were alive and disease free at a mean follow-up of 41.7 +/- 18.6 months. No biopsies were performed for benign lesions. Also, no cancers were missed when the protocol was followed.
Conclusions: Screening with CT can be done effectively in an area endemic for histoplasmosis while minimizing benign biopsies. (J Thorac Cardiovasc Surg 2011;141:688-93)”
“In rats, hedonic ultrasonic vocalizations (USVs) is a validated model of positive affect and is best elicited by rough-and-tumble play.
