(7) Lumbar muscularity was expressed by two ratios; the ratio between the Acs of the right psoas and the Acs of the intervertebral disc (P:disc), and the ratio between the combined Acs values of the right erector spinae and quadratus lumborum and the Acs of the disc (ESQL:disc).
(8) The purpose of this study was to detect any changes in the erector spinae muscles in patients undergoing surgery for lumbar disc herniation (LDH) and to analyze which factors (sex, age, the level and site of disc protrusion, and duration of symptoms) would be related to these changes.
(9) Fibres taken from erector spinae (Es), plantaris (Plt), diaphragm (Dia) and soleus (Sol) muscles of adult rabbits were pretyped as fast-twitch-glycolytic (FG), fast-twitch-oxidative-glycolytic (FOG), slow-twitch-oxidative (SO) or promiscuous (P) using a combination of histochemical staining and PAGE.
(10) Subsequently, cadaveric dis-sections indicated that the erector spinae muscles are contained within a well-developed fascial sheath.
(11) The demonstration of loss of sweating to indirect body heating, which also is usual suggests that the defect is central or on the efferent side of the reflex and a normal pilo-erector response to acetylcholine confirms this as preganglionic.
(12) In the control specimens taken from the contralateral groin, adrenergic nerves were seen in the erector pili muscles and as networks around arteries and arterioles.
(13) Intramuscular pressure in the erector spinae muscle was measured during exercise with the microcapillary infusion method in 12 highly selected patients with recurrent low-back pain.
(14) Histochemical studies of the thoracic part of the erector spinae muscles in scoliosis have shown a consistently higher proportion of Type 1 fibers on the convex side.
(15) True, a band shouldn't be judged by its name, but they sound like Fleetwood Mac (or, by their own admission, Jethro Tull); whereas with the Nipple Erectors, Slaughter & the Dogs or the Snivelling Shits, you tended to know what to expect.
(16) To evaluate the role of reflexes related to the lumbar proprioceptors in maintenance of body equilibrium, changes in equilibrium function of the eyes and body were observed after unilateral procainization of the lumbar erector muscles.
(17) This process would stabilize the pelvis and permit the erector spinae to extend the trunk more efficiently.
(18) Annulus erector motoneurons, which contain ACh and a peptide resembling FMRFamide, first developed electrical coupling when the two stumps were in contact and then, later, bi-directional chemical transmission.
(19) The erector spinae muscle was found to be heavily loaded during exercise with an average muscle contraction pressure of 175 mm Hg.
(20) Infiltration of the retroperitoneal muscles and an abscess within the erector spinae were also seen.
(n.) An organ which, by its contraction, produces motion.
(n.) The contractile tissue of which muscles are largely made up.
(n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
(n.) See Mussel.
(1) The extents of phospholipid hydrolysis were relatively low in brain homogenates, synaptic plasma membranes and heart ventricular muscle.
(2) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(3) These immunocytochemical studies clearly demonstrated that cells encountered within the fibrous intimal thickening in the vein graft were inevitably smooth muscle cell in origin.
(4) We have amended and added to Fabian's tables giving a functional assessment of individual masticatory muscles.
(5) During the performance of propulsive waves of the oesophagus the implanted vagus nerve caused clonic to tetanic contractions of the sternohyoid muscle, thus proving the oesophagomotor genesis of the reinnervating nerve fibres.
(6) Muscle weakness and atrophy were most marked in the distal parts of the legs, especially in the gastrocnemius and soleus muscles, and then spread to the thighs and gluteal muscles.
(7) No monosynaptic connexions were found between anterodorsal and posteroventral muscles except between the muscles innervated by the peroneal and the tibial nerve.
(8) Thus adrenaline, via pre- and post-junctional adrenoceptors, may contribute to enhanced vascular smooth muscle contraction, which most likely is sensitized by the elevated intracellular calcium concentration.
(9) In addition to their involvement in thrombosis, activated platelets release growth factors, most notably a platelet-derived growth factor (PDGF) which may be the principal mediator of smooth muscle cell migration from the media into the intima and of smooth muscle cell proliferation in the intima as well as of vasoconstriction.
(10) Further, the maximal increase in force of contraction was measured using papillary muscle strips from some of these patients.
(11) Peripheral eosinocytes increased by 10%, and tests for HBsAg, antiHBs, antimitochondrial antibody and anti-smooth muscle antibody were all negative.
(12) When subjects centered themselves actively, or additionally, contracted trunk flexor or extensor muscles to predetermined levels of activity, no increase in trunk positioning accuracy was found.
(13) A definite relationship between intelligence level and the type of muscle disease was found.
(14) After vascular injury, smooth muscle cells proliferate, reaching a maximum rate at day 2.
(15) In the absence of an authentic target for the MASH proteins, we examined their DNA binding and transcriptional regulatory activity by using a binding site (the E box) from the muscle creatine kinase (MCK) gene, a target of MyoD.
(16) Only the approximately 2.7 kb mRNA species was visualized in Northern blots of total cellular and poly(A+) RNA isolated from cardiac ventricular muscle.
(17) The variation of the activity of the peptidase with pH in the presence of various inhibitors was investigated in both control and insulted muscle fibres.
(18) Recent studies have shown that an aberration in platelet-derived growth factor gene expression is unlikely to be a factor in proliferation of smooth-muscle cells.
(19) This sling was constructed bu freeing the insertion of the pubococcygeus and the ileococcygeus muscles from the coccyx.
(20) Their effects on various lipid fractions, viz., triglycerides (TG), phospholipids, free cholesterol, and esterified cholesterol, were studied in liver, plasma, gonads, and muscle.
