The Potential Benefits of Legumes Germ and Cereal Grains on Roosters' Reproductive Performance.

Vit E is known as one of the most important antioxidant. It has been previously approved that cereal grains and leafy plants are considered as the main source for α-tocopherol (Vit E). One of the recommended therapies for male infertility would be the Vit E therapy. Following Vit E consumption the semen parameters such as sperm concentration, ejaculation volume, sperm progressive motility, and in vitro function (zone binding assay) have been significantly improved. Therefore, present study was designed to investigate the effects of oral administration of cereal grain and seeds on reproductive performance of local cocks. During a period of 63 weeks, 100 local (Iraqi breed) rooster chicks were randomly divided into the five groups (n=20). Animals in group 1 served as control group and had not received any supplementations in their diet. The animals in the Groups 2-5 received diets which were fortified with 100, 200, 300, and 400 g of cereal grain and legume seeds pure germs. The results of the current study showed that the total number of spermatozoa and percentages of abnormal sperm were decreased by adding more amount of germ of cereal grain and seeds (P<0.01). Increased germ of cereal grain and seeds was not associated with pH volume, colour, consistency and motility of the sperm compared to corresponding rates in control group. Phospholipids content and thiobarbituric acid reactive substance of semen sample as well as density of ejaculate (sperm/µl) were decreased by adding increasing germ of cereal grain and seeds in diet of rosters. Weight of testis decreased by increasing levels of cereal grains and legume seeds germ in the diets (P<0.05).

Detection of Salmonella spp. by Traditional and PCR Assays in Raw Milk, Maysan, Iraq.

Salmonella spp are characterized as rod- shaped, motile, gram- negative bacteria which has the ability to infect animals and human. Salmonella spp occasionally causes sickness while in most cases not lead to severe symptoms. Analyzing milk for Salmonella spp. is not routine but traditional culture methods are used to evaluate the health condition of the dairy products. However, the antibody-based and nucleic-acid- based methods are practical for identifying Salmonella spp. Therefore, this research was designed to evaluate the use of traditional culture methods and PCR in detection of the presence of Salmonella spp. in raw milk samples in, Maysan Iraq. A total number of 130 raw milk samples collected from Maysan Iraq. All the samples were analyzed for the presence of Salmonella spp. using traditional culture method and polymerase chain reaction (PCR). The culture method used in this experiment were done by using pre-enrichment, enrichment, selective plating and biochemical tests. The results of this traditional technique were compared with the results obtained from PCR method. The PCR was performed using a 284bp sequence of the invA gene. The results showed that 8 (7.07%) of samples were identified as salmonella positive using traditional culture technique but 14 (12.3%) samples were detected as salmonella positive by PCR method. The results of the current research revealed that the traditional culture based methods are generally time costuming and labor intensive but the development of new rapid methods including DNA based methods such as PCR are more sensitive and have dramatically decreased the time necessary for the detection of bacteria.

Paediatric surgical response to an 'adult' COVID-19 pandemic.

INTRODUCTION: The Coronavirus Disease 2019 (COVID-19) has dramatically affected global healthcare systems. We aimed to determine the response of our paediatric surgical fraternity to a disease that overwhelmingly affects adults. MATERIALS AND METHODS: We conducted a cross-sectional questionnaire-based study over 6 weeks during a federally mandated lockdown. Using snowball sampling, we recruited paediatric surgeons, trainees and medical officers from paediatric surgical units in Malaysia. The anonymous online questionnaire covered sociodemographic information, changes in patient care, redeployment, concerns regarding family members, and impact on training. Mental well-being was assessed using the Depression, Anxiety and Stress Scale (DASS-21). Kruskal-Wallis, ANOVA and multiple regression analysis was used, with significance level 0.05. RESULTS: Of the 129 eligible participants, 100(77%) responded. Junior doctors had clinically higher levels of depression, anxiety, and stress. Age <30 years was significantly associated with anxiety. Junior doctors believed that redeployment led to loss of surgical skills (p<0.001) and trainees felt that clinical application of knowledge had reduced (p<0.020). CONCLUSION: Specific to our paediatric surgical community, this study highlights areas of concern, particularly among junior doctors. It is likely that recurrent cycles of the pandemic will occur soon. These issues must be addressed to preserve the mental and emotional well-being of all health care workers.

Cardiac magnetic resonance indices reflecting pulmonary regurgitation burden after tetralogy of Fallot repair.

AIM: To investigate cardiac magnetic resonance (CMR)-derived parameters to determine a convenient index reflecting the degree of pulmonary regurgitation (PR) after Tetralogy of Fallot (TOF) repair. MATERIALS AND METHODS: Sixty-three patients (age at CMR study, 23.6 [10.2-34.7] years, 55.6% male) underwent CMR after TOF repair. PR was quantified using ventricular stroke volume difference and phase-contrast mapping of the main pulmonary artery flow. In both approaches, the PRV index (PRVI) and the PR fraction (PRF) were calculated and correlated to the right ventricle end-diastolic volume index (RVEDVI) and the right ventricle end-systolic volume index (RVESVI). RESULTS: No statistically significant difference was observed between the PR volumes and the PRF measured by the stroke volume difference or the phase-contrast method. The PRVI was better correlated to RVEDVI and RVESVI than the PRF. CONCLUSION: The PRVI exhibits more correlation to the RVEDVI than PRF. Thus, it could be a preferable parameter to reflect the PR burden.

A single dose of ranitidine 150 mg modulates oesophageal acid sensitivity in patients with functional heartburn.

BACKGROUND: The rapid onset and symptomatic response to histamine-2 receptor antagonists prior to the pharmacological effect on acid secretion suggests a different mechanism of action. AIM: To determine if ranitidine decreases oesophageal sensitivity to chemical and mechanical stimulation, potentially via oesophageal histamine receptors. METHODS: A total of 18 patients with functional heartburn received oral ranitidine 150 mg b.d. or placebo for 7 consecutive days in a double-blind randomized crossover design and underwent Barostat balloon distention and Bernstein acid infusion on study day 1 (90 min postdose) and study day 7. First sensation and pain were recorded and pain severity was rated on a 5-point Likert scale and a 100 mm visual analogue scale. Least square mean values were generated and one-tailed t-tests were performed. RESULTS: After a single dose of ranitidine 150 mg, time to pain with oesophageal acid infusion was increased by 29% (P < 0.05) and visual analogue scale and Likert scores were decreased by 20% (P < 0.06) and 23% (P < 0.02), respectively compared with placebo. After 1 week of ranitidine, positive alterations in sensory parameters persisted. Balloon distention sensory parameters were not altered by ranitidine. CONCLUSIONS: Ranitidine significantly decreased oesophageal sensitivity to acid. Failure of ranitidine to improve balloon sensory parameters supports existence of multiple sensory pathways in the oesophagus.

Synergy between low-dose ranitidine and antacid in decreasing gastric and oesophageal acidity and relieving meal-induced heartburn.

BACKGROUND: The pathophysiology of recurrent postprandial heartburn and the basis for the effectiveness of antacids or low doses of histamine H2-receptor antagonists have not been well studied. METHODS: The selected subjects (n=26) had heartburn more than four times a week for at least 2 months, which was responsive to antacids. Gastric pH and oesophageal pH were measured for 1 h before, during, and 4.5 h after ingestion of a meal over 0.5 h. Heartburn severity was assessed at 15-min intervals beginning at the end of the meal. Each subject randomly received placebo, 75 mg ranitidine, 420 mg calcium carbonate, and ranitidine plus calcium carbonate. Values for pH were converted to acid concentration (mM) and integrated acidity was calculated from the cumulative, time-weighted means of the acid concentrations for every second of the postprandial recording period. RESULTS: There was a close temporal relationship between heartburn and oesophageal acidity. Most oesophageal acid exposure occurred over a 90-min period that began approximately 45 min after the end of the meal. During this period the gastric acid concentration was less than 5% of maximal. Ranitidine significantly decreased gastric but not oesophageal acidity, whilst antacid significantly decreased oesophageal but not gastric acidity. Ranitidine plus antacid significantly decreased both gastric and oesophageal acidity. Antacid alone and ranitidine plus antacid significantly decreased heartburn severity. CONCLUSIONS: Determining integrated gastric and oesophageal acidity provides novel information regarding the pathophysiology of meal-induced heartburn as well as the actions of low-dose ranitidine and antacid. For subjects with meal-induced heartburn, treatment with low-dose ranitidine plus antacid is particularly effective in decreasing gastric and oesophageal acidity as well as heartburn severity.
