Background: Coronary artery disease (CAD) is often silent in diabetic patients, and it is typically in ad-vanced stages of development by the time it manifests. Various forms of stress testing have been investigated to detect obstructive CAD in diabetes mellitus. Ob-jectives: To assess the diagnostic value of dobutamine stress pulsed-wave Doppler tissue imaging (DTI) compared with standard wall motion analysis in de-tection of myocardial ischemia in diabetic patients with suspected CAD. Methods: The study comprised 46 diabetic patients with suspected CAD underwent dobutamine stress echocardiography (DSE) with DTI within 4 weeks before coronary angiography(CA). Dobutamine infusion started at 5 μ/kg/min and in-creased up to 40 μ/kg/min with additional atropine during submaximal heart rate responses. In addition to wall-motion score index (WMSI) analysis, pulsed- wave DTI examination of basal and mid segments of posteroseptal, lateral, anterior, inferior and antero- septal walls was performed. Myocardial velocities were measured at rest in the apical 4, 3 and 2-cham- ber views. The measurements were repeated at low dose (10 - 15 μ/kg/min) and at peak stress (40 μ/kg/min). DTI measurements included peak systolic velocity (S), peak early diastolic velocity (E) and peak late diastolic velocity (A) and the results were com-pared to WMSI analysis. Patients were classified into two groups according to CA results;group (I) di-abetics with positive CA (n = 27) and group (II) di-abetics with negative CA (n = 19). Results: There was no significant difference between the two groups in duration of diabetes, global WMSI at rest or the ? changes (stress-rest/rest) of WMSI (P > 0.05). Global S and global E were significantly lower in group I compared to group II at peak stress (11.3 ± 3.7 cm/sec vs. 14.5 ± 2.2 cm/sec, p < 0.01) and (11.3 ± 1.6 cm/sec vs. 13.1 ± 2.1 cm/sec, p < 0.01) respectively. The cutoff points for global S and global E to detect obstructive CAD in diabetics were

Background: Milk is a healthy human nutrient, which is fermented to yogurt by lactic acid bacteria, mainly Streptococcus salivarius ssp, thermophilus and Lactobacillus. delbrueckii ssp. bulgaricus. This study aimed to isolate thermophilic starter bacteria from homemade yogurt made in Gaza Strip. The study sought to define both the biochemical and molecular characteristics of the isolated bacteria. Results: Three of the isolates were identified as Streptococcus thermophiles while two isolates were recognized as Lactobacillus delbrueckii ssp. bulgaricus. All five identified isolates showed worthy acidification capacity. Based on these characters, strains were applied for making yogurt either as single pure cultures or as mixed cultures. When using mixed cultures from S. thermophiles and L. bulgaricus, all tested combinations showed positive results. Conclusion: Isolated strains showed remarkable biotechnological characters. The isolates are expected to stimulate and improve quality of the yogurt when they are used as mixed starter cultures.
