A 19-year-old male college basketball player experienced onset of pain after playing 4 games in 2 days. Clinical examination revealed mild swelling over the mid-left tibia. There were no signs of infection. We obtained radiographs (Fig. 1). The radiological differential diagnosis at this stage included focal cortical abscess related to infection, stress fracture and osteoid osteoma. Computed to...

Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R979–R989, 1999.—The mechanosensory activity generated by ventricular epicardial sensory neurites associated with afferent axons in thoracic sympathetic nerves was correl...

Callera, João Carlos, Leni G. H. Bonagamba, Anne Nosjean, Raul Laguzzi, and Benedito H. Machado. Activation of GABAA but not GABAB receptors in the NTS blocked bradycardia of chemoreflex in awake rats. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1902–H1910, 1999.—In the present study we analyzed effects of bilateral microinjections of muscimol (a GABAA agonist) and baclofen (a GABAB agonist...

Sharma, Ram V., Enqing Tan, Shengyun Fang, Milind V. Gurjar, and Ramesh C. Bhalla. NOS gene transfer inhibits expression of cell cycle regulatory molecules in vascular smooth muscle cells. Am. J. Physiol. 276 (Heart Circ. Physiol. 45): H1450–H1459, 1999.—The mechanisms of nitric oxide (NO)-mediated inhibition of vascular smooth muscle (VSM) cell proliferation are still obscure. Cyclins A and E ...

O’Connor, Timothy P., Mandy M. Lam, and Jared Diamond. Magnitude of functional adaptation after intestinal resection. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1265–R1275, 1999.—Intestinal adaptation after resection has been much studied, but rarely examined in an integrative context. Hence we assessed the effects of resection and subsequent adaptation on the quantitative...

Rauch, Matthias, and Herbert A. Schmid. Functional evidence for subfornical organ-intrinsic conversion of angiotensin I to angiotensin II. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R1630–R1638, 1999.—Using extracellular electrophysiological recording in an in vitro slice preparation, we investigated whether ANG I can be locally converted to the functionally active ANG II w...

Cui, Jian, Satoshi Iwase, Tadaaki Mano, and Hiroki Kitazawa. Responses of sympathetic outflow to skin during caloric stimulation in humans. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R738–R744, 1999.—We previously showed that caloric vestibular stimulation elicits increases in sympathetic outflow to muscle (MSNA) in humans. The present study was conducted to determine the e...

Hayward, Linda F., and Robert B. Felder. Electrophysiological properties of rat lateral parabrachial neurons in vitro. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R696–R706, 1999.—Anatomical studies have demonstrated that the lateral parabrachial nucleus (LPBN) is composed of at least seven separate subnuclei distinguished by cell morphology, spatial clustering, and afferent...

Laboratory-bred females of Culex quinquefasciatus, Aedes aegypti and Aedes albopictus from the insectarium, Unit of Medical Entomology, Institute for Medical Research were used in the experiment. The late third stage of the F0 larvae which survived the high selection pressure of malathion, permethrin and temephos were reared and colonies were established from adults that emerged. Cx. quinquefas...

Bewick, N. L., C. Fernandes, A. D. Pitt, H. H. Rasmussen, and D. W. Whalley. Mechanisms of Na1-K1 pump regulation in cardiac myocytes during hyposmolar swelling. Am. J. Physiol. 276 (Cell Physiol. 45): C1091–C1099, 1999.—We have previously demonstrated that the sarcolemmal Na1-K1 pump current (Ip) in cardiac myocytes is stimulated by cell swelling induced by exposure to hyposmolar solutions.
