atropine/neoplasms

Muscarinic acetylcholine receptors (mAChR) are expressed in cells without nervous origin. mAChR are up-regulated in tumor cells and their stimulation can modulate tumor growth. In this work we investigated the ability of mAChR activation to induce tumor cell death. We studied the action of a

Tumor necrosis factor-alpha (TNF-alpha) likely plays a role in the pathophysiology of myocardial depression observed in septic shock. To evaluate the hemodynamic effects of TNF-alpha in vivo while eliminating the influence of altered sympathetic tone, eight conscious chronically instrumented dogs

Cardiac arrest in the operating room is a life-threatening event with multiple causes. We report the case of a 53-year old female patient with no particular past medical history scheduled for surgery to manage small intestine cancer. Twenty minutes after anesthetic induction the patient had asystole

Carbamylcholine, acting via a pharmacologically specific receptor, had the ability to activate effector populations of spleen cells from female BALB/cfC3H and BALB/c mice; those cell populations were then significantly reactive in vitro against syngeneic tumor target cells but were only minimally

A 58-year-old male was scheduled to undergo radical gastrectomy for cancer under general anesthesia. The patient developed agitation and irregular breathing after receiving a single dose of atropine (0.5 mg) to treat bradycardia immediately prior to induction of anesthesia. Within 5 min after the

OBJECTIVE This phase II study was designed to evaluate the efficacy of irinotecan administered intravenously once every 3 weeks in pediatric patients with recurrent or refractory rhabdomyosarcoma. METHODS A total of 35 patients younger than age 20 years, with refractory or relapsed rhabdomyosarcoma

OBJECTIVE Subcutaneous (SC) octreotide has been shown to effectively relieve chemotherapy-induced diarrhea (CID) refractory to conventional therapy but requires t.i.d. injections. A microencapsulated, long-acting formulation (LAR) of octreotide has been developed for once-monthly intramuscular (IM)

The effect of bromoacetylcholine on mouse neuroblastoma C-1300 was investigated in cell culture as well as in A/J mice. In vitro, bromoacetylcholine (1 X 10(-5) M) was a potent cytolytic agent and produced an additive effect in combination with vincristine (3 X 10(-9) M). Since the choline

Muscarinic receptors (CHRM) are overexpressed in colon cancer. To explore a role for muscarinic receptor signaling in colon cancer metastasis, we used human H508 and HT29 colon cancer cells that coexpress epidermal growth factor (ERBB) and CHRM3 receptors. In a wound closure model, following 8-h

Breast cancer is a major health problem and accounted for 11.6% of all new cancer cases and 6.6% of all cancer deaths among women worldwide in 2018. However, its etiology has remained elusive. According to epidemiological studies, environmental factors are influencing the increase in the incidence

Lung cancer is the leading cause of cancer deaths worldwide, with a high morbidity and less than 20% survival rate. Therefore, new treatment strategies and drugs are needed to reduce the mortality of patients with lung cancer. α7 nicotinic acetylcholine receptor (α7 nAChR), as a receptor of nicotine

The ability of tumor cells to stimulate adaptive immunity, particularly by inducing anti-tumor antibodies (Abs), has been extensively reviewed. LM3 is a tumorigenic cell line derived from a murine mammary metastatic adenocarcinoma that spontaneously overexpressed mAchR. Here we investigate the

Irinotecan is a novel anticancer drug that has worked wonders in combination with other anticancer drugs. It can be used as a single chemotherapy agent in colonic cancer treatment or in combination with 5-fluorouracil. Irinotecan has been found a better salvage therapy in patients who are resistant

BACKGROUND Drooling occasionally occurs in cancer patients, impairing their quality of life. Recommended treatment includes the use of anticholinergic drugs, but there is a lack of scientific evidence supporting it; some recent reports tested the use of sublingual atropine, and further controlled

Although epidemiological studies indicate an association between elevations in fecal bile acids and the development of colorectal cancer, the cellular mechanism for the proliferative actions of bile acids is not clear. Studies from other laboratories indicate a paradoxical pro-apoptotic action of
