Ripened cheese is among fermented food the most often associated with poisoning from biogenic amines. The influence of ripening time, heat treatment milk and effect using a different ewe breed on amine (BA) content Zamorano was studied by high-performance liquid chromatography. Physicochemical, proteolytic microbiological parameters were also studied.BA increased significantly during their final values around 400 mg kg(-1). Cheeses elaborated raw duplicated concentration BA relative to those...

Aims: To analyse the expression of metalloproteinases (MMPs) and their inhibitors (TIMPs) in ductal carcinoma situ breast (DCIS). Methods results: An immunohistochemical study was performed 56 patients with pure DCIS, 39 DCIS adjacent to invasive (IDC) 63 T1 IDC, using tissue microarrays specific antibodies against MMPs TIMPs. Immunohistochemical results were categorized a software program. The data analysed by unsupervised hierarchical cluster analysis each cellular type. IDC showed higher...

Physicochemical characteristics, proteolysis and lipolysis were studied throughout the ripening of eight batches a traditional Spanish variety made from raw cow's milk, in order to establish basis for its industrial production.The main compositional characteristics this cheese after 60 days high proportion total solids (TS; 752 g kg⁻¹ cheese), an average content protein (452.8 TS) fat (475.1 presence residual lactose (12.5 TS). Its pH value (4.04) was extremely low. Phosphorus (5.13 sodium...

Mollicutes are frequently isolated from sperma of infertile men. The potential effect on the fertility mollicute infection is controversial as antibiotic therapy. In our andrological patients, prevalence mollicutes approximately 10%. To evaluate benefit therapy, we investigated two groups patients: group 1-patients with positive or negative cultures and normal spermiogram; morphological changes spermatozoa were particularly evaluated (n = 40); 2 - patients treated doxycycline erythromycin....

A total of 30 Zamorano-type cheeses were manufactured in order to study the effects milk conjugated linoleic acid (CLA) content, ripening time, and interactions between both on fatty (FA) profile. Cheeses elaborated from with a high CLA content showed higher contents vaccenic, oleic, alpha-linolenic (ALA), CLA, monounsaturated (MUFA) polyunsaturated (PUFA) FA, lower capric, lauric, myristic, palmitic, estearic, linoleic, saturated (SFA) FA than cheese low content. Content unsaturated C18...
