The intrinsic contractile properties of isolated left ventricular trabecular periods of 24, 40, and 53 days were compared with those from 35 weight-matched food-deprived animals and 25 ad libitum fed controls. Contraction mechanics were measured for each muscle when stretched to the peak of its length tension curve at 28 degrees C in oxygenated Krebs-Henseleit solution. Although both thiamine-d...

Polygraphic recordings were made before and after o6 mg of sublingual nitroglycerin in 20 normal subjects and in 20 patients with ischaemic heart disease. Thefollowing effects of nitroglycerin were observed in both groups: shortening of ejection time, prolongation of pre-ejection period and also of isometric contraction time unrelated to decrease in systolic blood pressure, and increase in hear...

Sonographic patterns for the Doppler ophthalmic test (DOT) were determined by reviewing the type of graphic record obtained from 25 patients who had undergone angiography. Three principal patterns were identified, depending upon whether there was augmentation (Type 1), diminution (Type 2) or no change (Type 3) in the character of the supraorbital Doppler signal upon temporal artery compression....

Controlled cerebral ischemia was produced in rabbits by bilateral occlusion of the common carotid arteries and restriction of collateral blood flow by a decrease of the systemic arterial pressure to a desirable level (by hemorrhage into a pressurized reservior system). The following circulatory parameters were simultaneously monitored: systemic arterial pressure (SAP), pressure in the circle of...

background and aims. autogenous onlay bone grafting is a common procedure for alveolar ridge augmentation. it has been suggested that the amount of healed bone after this technique would be significantly less than the initial quantity. the aim of this study was to determine the relationship between the various parameters influencing the outcome of ridge augmentation procedures. materials and me...

the aim of this study was to determine the feasibility of coupling an electrochemical process with a biological treatment in order to degrade phosmet, an organophosphorous pesticide. the absence of biodegradability of phosmet by pseudomonas fluorescens and activated sludge was verified in our operational conditions. so, a conventional biological treatment is not appropriate for phosmet polluted...

Careful treatment planning, space management, augmentation of bone and attention to the details of implant surgical and prosthetic techniques are important factors when treating anterior maxilla specially replacement of missing teeth. This case report addresses a chair-side ridge augmentation procedure using autograft bone harvested with trephine drills and placed without using screws and the f...

We have studied the relationship between the occurrence of chromatin diminution and the developmental behavior of somatic blastomeres in early development of the nematode Parascaris univalens. A cytological and immunocytochemical analysis of chromatin diminution was performed in P. univalens embryos exposed to 'vegetalizing' (LiCl) and 'animalizing' (NaSCN) substances during early developmental...
