The aim of this work was to characterize visual properties, instrumentally measured colour properties, field fungi presence and Alternaria toxins levels in wheat samples grown under conditions aimed at inhibition and stimulation of wheat infection with fungi from the Alternaria genus. Experiment was carried out on the wheat treated by fungicide and wheat inoculated by Alternaria spp., while non treated wheat was used as a control. Statistically significant difference was observed between all three treatments using visual scale. Protected wheat samples were significantly different from other samples in terms of all measured colour parameters while inoculated and control wheat samples were significantly different in terms of lightness and dominant wavelength. Identification of field fungi in the all examined wheat samples showed that the dominant mycotoxigenic fungus was Alternaria spp., followed by Fusarium spp. The content of Alternaria toxins in samples of wheat hulls and dehulled kernels point out at higher concentrations of Alternaria toxins in hulls than in dehulled kernels.

The SSEPs obtained from 19 schizophrenics defined by RDC, DSM–III and PSE criteria Were compared with those from a control group of healthy volunteers. Previous findings of an abnormal lack of lateralising response in schizophrenic patients were not replicated. No significant difference in either amplitude or morphology between the traces obtained from the two groups were recorded. Ipsilateral and contralateral latencies for stimulation of the left and right index finger showed no significant difference in peak latency for any component between patient and control group. When mean peak-to-peak amplitudes were plotted the contralateral component was always greater in amplitude than the ipsilateral one. An objective measure of the degree of lateralisation, the percentage lateralisation quotient, showed no lateralisation differences between the patient and control groups. A case of myogenic contamination of ipsilateral components was observed calling into doubt findings where no temporal region monitoring has been performed.

Abstract Rotavirus was the an important causative agent of acute gastroenteritis in children. In China, rotavirus was positive in approximately 30% of the diarrhea children and become a serious public problem. This study was carried out to investigate the clinical and molecular epidemic characterization of rotavirus infection among children under 5 years old with acute diarrhea in Shandong province, China. From July 2017 to June 2018, a total of 1211 fecal specimens were detected and the prevalence of rotavirus infection was 32.12%. The mean age of positive children was 12.2 ± 10.9 months and the highest infection rate was observed in children aged 7–12 months with a rate of 41.64%. G9P[8] (76.61%) was the most prevalent combinations followed by G2P[4] (7.20%), G3P[8] (3.60%) and G9P[4] (2.06%). In addition to diarrhea, vomiting, fever and dehydration were the most common accompanied symptoms. In general, there was no significant difference in clinical manifestations among different age groups. However, the clinical manifestations between vaccinated and unvaccinated children were significantly different. Vaccinated children showed lower incidence and frequency of vomiting, lower incidence and degree of dehydration, lower incidence of severe cases than unvaccinated children. The findings suggested necessary to continue rotavirus strains surveillance in order to monitor the change of prevalent genotype. Moreover, introducing vaccine into national immunization program to prevent and control rotavirus infections is needed in China.

Femur marrow from fasted, bile duct ligated, and control rabbits was examined with supravital stains for occurrence of nucleated cells, including reticulocytes. There were marked decreases in concentration of these cellular elements in both treated groups of rabbits, although the reticulocyte population in the marrow of the bile duct ligated rabbit was considerably higher than in the fasted rabbit. Apparently there was more stimulation of erythropoiesis in the marrow of the jaundiced rabbit in spite of body wt. loss comparable to that of the fasted rabbit. Sodium and potassium analyses of marrow indicated no significant difference in fasted marrow from control marrow, the Na/K ratio being about 0.5. However, both sodium and potassium rose significantly in the bile duct ligated marrow, although the Na/K ratio was not appreciably altered. Also, there was evidence of plasma potassium increase with sodium decrease in the bile duct ligated rabbit.

Molecular Description

Introduction: Although Cysticercus tenuicollis is one of the most economic and veterinary important parasite in Iraq, scanty molecular characterization exists for this helminth. This study aimed to determine the prevalence and molecular description of C. tenuicollis isolates from sheep in Kalar district of Iraq. Methodology: A total of 2,906 slaughtered sheep were examined post-mortem. Up to 20 samples of C. tenuicollis was extracted and amplified using mitochondrial COX1 gene. Results: The overall prevalence rate was 6.88%, and female sheep recorded higher rate of infection (24.35%) than male (6.16%) with significant difference (p<0.05). The molecular results showed 14 haplotypes for COX1 gene and the pairwise nucleotide variation among them was ranged from 0.2 to 2.6%. Twelve out of fourteen haplotypes of C. tenuicollis involving one to three base mutations were discovered in Kalar, Iraq for the first time and this could be a unique mutation internationally and did not registered previously. Eleven newly recorded haplotypes involved only one single mutation and the remaining one involved three mutations. Phylogenetic interpretation showed that Cysticercus tenuicollis-Kalar isolate were clustered in one clade, and closely related to isolates discovered in Nigeria, China, Turkey, Poland, and Iran. Conclusions: This study provided a new record data on prevalence and discovered novel strains of C. tenuicollis in the study area for the first time named Cysticercus tenuicollis-Kalar isolate. Novel haplotypes might consider endemic genetic characterization of this metacestode. The present data may be useful to provide a good molecular background for future preventive and control programs.

Following partial nephrectomy in juvenile metamorphosed Xenopus laevis the mitotic activity in the regenerating kidney reached its maximum on the 6th day and returned to its normal level by the 16th day. The mitotic activity was measured in the pronephros and epidermis of prefeeding Xenopus larvae (stage 38) at different intervals after their implantation into the lymph sacs of partially nephrectomized and control metamorphosed hosts. Ten days after partial nephrectomy, during the period of increased mitotic activity in the regenerating kidney of the host, the mitotic activity in the implant pronephros was twice as high as that in the implant pronephros of the control hosts. Eighteen days after partial nephrectomy when the mitotic activity in the regenerating host kidney had returned to normal, there was no difference between the mitotic activity of pronephros of implants in nephrectomized and control hosts. There was no significant difference between the mitotic activity of epidermis of the implants in nephrectomized and control hosts, nor was there any difference between the epidermal mitotic activity in implants examined 10 and 18 days after host nephrectomy. It was concluded that a circulating factor (or factors) responsible for the control of mitotic activity in the regenerating host kidney enters the implant through its vascular supply and influences the mitotic activity in the homologous embryonic tissue. It is possible that this factor is a tissue-specific mitotic inhibitor synthesized by the host kidney.

ABSTRACT A method for the fractionation of the urinary 17-ketogenic steroids with no oxygen grouping at C11 and those oxygenated at C11, is applied to the clinical problems of congenital adrenal hyperplasia. In normal children the mean ratio of the non-oxygenated to oxygenated steroids is 0.24. In childrern with congenital adrenal hyperplasia the ratio is 2.3. The reason for this difference in ratio is discussed. The changes in ratio found under stimulation of the adrenal gland with exogenous or endogenous corticotrophin and the suppression with cortisone therapy are studied. This test can be applied to isolated samples of urine, a major advantage in paediatric practice, and can be carried out in routine laboratories. It is found to be reliable in the diagnosis and sensitive in the control of congenital adrenal hyperplasia.

Introduction: Ocimum basilicum (OB), a herb known for its antihypertensive, anticholinesterase and antioxidant properties was investigated for possible intraocular pressure (IOP) lowering effects in rabbits with ocular hypertension (OHT). Methods: The IOP lowering effect of a single drop of OB extract (OBE) was evaluated in oculonormotensive rabbits using three concentrations (0.25, 0.5 and 1% w/v). The concentration showing maximum IOP reduction was further evaluated in rabbits with water-loading and steroid-induced OHT. Results: IOP lowering effect of OBE 0.5% in oculonormotensive rabbit eyes was significantly greater compared to OBE 0.25% (p<0.05) but was comparable (p>0.05) to OBE 1%. Therefore, 0.5% concentration was selected for further evaluation. Pretreatment with OBE (0.5%) caused significantly lower increase in IOP after water loading amounting to 23.39% above baseline as compared to 54.00% in control eye, 15 minutes post water loading. At 60 minutes, post water loading, mean IOP rise was 95.12% and 63.58% in control and test eyes, respectively. Significant difference between the mean IOP of two eyes persisted during the 2nd hr. In rabbits with steroid induced OHT, OBE 0.5% produced a mean IOP reduction of 24.73% at the end of first hr and the mean peak IOP reduction of 31.63% was observed at the end of 2 hr. A significant difference between the IOP of test and control eyes persisted from 1 to 6 hr. Conclusions: Ocimum basilicum seed extract showed significant IOP lowering effect in rabbits with water loading and steroid induced OHT, however, its utility as an effective antiglaucoma medication needs further investigations.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.
