Gastric cancer in humans arises in the setting of oxyntic atrophy (parietal cell loss) and attendant hyperplastic and metaplastic lineage changes within the gastric mucosa. Helicobacter infection in mice and humans leads to spasmolytic polypeptide-expressing metaplasia (SPEM). In a number of mouse models, SPEM arises after oxyntic atrophy. In mice treated with the parietal cell toxic protonopho...

Pemetrexed and Carboplatin are two well-known chemioterapic agents used for the treatment of many tumors, especially for lung cancer and mesothelioma. Peripheral ischemic events related to Pemetrexed and Carboplatin are rarely reported. We herein report a case of lower limb acute ischemia related to combined treatment of Pemetrexed and Carboplatin. A 68-year-old woman was given the chemiotherap...

Essential oils are complex mixtures of several components endowed with a wide range of biological activities, including antiseptic, anti-inflammatory, spasmolytic, sedative, analgesic, and anesthetic properties. A growing body of scientific reports has recently focused on the potential of essential oils as anticancer treatment in the attempt to overcome the development of multidrug resistance a...

In this paper, a crude methanolic extract from the stem bark of Prosopis cineraria, a plant native of Pakistan, was tested for its possible presence of spasmolytic, bronchodilator, and vasodilator activities in an attempt to validate some of its folkloric uses. Moreover, attempts were made to provide plausible explanations of the observed biological activities. The extract caused relaxation of ...

The centrioles of cnidarian sperm associate with striated specializations (pericentriolar processes) during spermiogenesis. Three functions have been proposed for the role of these structures: (a) an anchoring mechanism for the sperm flagellum, (b) a signal-transmitting mechanism for communication between sperm head and tal, and (c) a contractile mechanism involved in motor function of the sper...

BACKGROUND Dipyrone is an analgesic and antipyretic agent with a distinctive spasmolytic effect on smooth muscles. We recently showed that dipyrone significantly relaxed precontracted tracheal smooth muscle in guinea pig. OBJECTIVE To investigate whether this in vitro observation could be observed in vivo in the respiratory function parameters of asthma patients. METHOD Twenty-two patients,...
