1. The potencies of four series of N-alkyl-1,2,3-benzotriazinium iodides have been estimated on the frog rectus abdominis and chick biventer cervicis preparations.2. The partition coefficients between chloroform and water were measured for all of the compounds, as well as the ionization constants for some members of two of the series.3. The potencies of the compounds increased with the number o...

metastasis of gastroesphageal junction (gej) adenocarcinoma in skeletal muscle is rare and primary sites for skeletal muscle metastases are usually lung, renal and colorectal cancer. we have encountered with the first case report of solitary psoas muscle metastasis of gej adenocarcinoma. here we describe a 65 years old man was diagnosed with gej adenocarcinoma in tertiary hospital, tehran, iran...

The impact of prolonged bed rest on the cervical and upper thoracic spine is unknown. In the 2nd Berlin BedRest Study (BBR2-2), 24 male subjects underwent 60-day bed rest and performed either no exercise, resistive exercise, or resistive exercise with whole body vibration. Subjects were followed for 2 yr after bed rest. On axial cervical magnetic resonance images from the skull to T3, the volum...

background and objectives: sarcopenia is explained as the loss of muscle strength and muscle mass with aging‚ and is one of the major risk factors for metabolic diseases. cross-sectional studies demonstrate that vitamin d is associated with sarcopenia in both men and women. the aim of this study was to investigate the effect of vitamin d supplement consumption on muscle strength, muscle functio...

Australo-papuan death adders (Acanthophis spp.) are a cause of serious envenomations in Papua New Guinea and northern Australia often resulting in neurotoxic paralysis. Furthermore, victims occasionally present with delayed-onset neurotoxicity that sometimes responds poorly to antivenom or anticholinesterase treatment. This clinical outcome could be explained by the presence of potent snake pre...

A lethal neurotoxin protein (Toxin CM36) was isolated and purified from the Indian King Cobra (Ophiophagus hannah) venom by CM-Sephadex ion exchange chromatography and HPLC. The purified toxin had a SDSmolecular weight of 15 ± 0.5 kD. The UVabsorption spectra of Toxin CM36 showed a peak at 280 nm and an Emax at 343.8 nm, when excited at 280nm fluorescence. Toxin CM36 had an LDso of 3.5 J.lg120 ...

The nurse shark, Ginglymostoma cirratum, is an obligate suction feeder that preys on benthic invertebrates and fish. Its cranial morphology exhibits a suite of structural and functional modifications that facilitate this mode of prey capture. During suction-feeding, subambient pressure is generated by the ventral expansion of the hyoid apparatus and the floor of its buccopharyngeal cavity. As i...

A total of seven she-camels (3-4 years old) were slaughtered following the normal abattoir procedures in Khartoum state, Sudan. Longissimus thoracis (LT) muscle samples were aged for 1, 3, 5, and 7 days at 1-3° C. Chemical composition, muscle pH, drip loss (DL), water holding capacity (WHC), color, myosin heavy chain isoforms (MyHC) as well as lipid peroxidation (MDA) and vitamin E content were...
