Polyphenolic Fractions from Three Millet Types (Fonio,Finger millet,and Pearl millet): their Characterization and Biological Importance

BackgroundAs antioxidant-rich plant foods, cereals can impede lipid and starch breakdown in the human body, are germane to diabetes management.ObjectiveWe aim to identify newer sources of phytochemicals and health-promoting constituents desirable antidiabetic and antioxidant properties.MethodsThree millet types i.e. fonio (Digitaria exilis), finger millet (Eleusine coracana), and pearl millet (Pennisetum glaucum) available locally were investigated for antioxidant ability employing these assays i.e. DPPH, ABTS, H₂O₂, antidiabetic ability employing these assays i.e. α-amylase, α-glucosidase and inhibitory property on glycosylation formation. Preliminary characterization tools were employed i.e. UV-Visible spectroscopy (UV–visible) and Fourier-Transform Infrared Spectroscopy (FTIR) for the polyphenolic confirmation.ResultsThe absorbance intensity range 325–425 nm confirmed that polyphenolics are present in the three millet types; most of the biological results showed the activities are dose-dependent. Fonio millet extract revealed the highest activity against hemoglobin glycosylation (29.469 ± 0.399%) which compared favorably with the standard (acarbose) (29.354 ± 1.607%). Fonio millet extract also showed the best antioxidant activity (significantly higher% inhibition value = 47.909 ± 3.472) and the pearl millet revealed the least antioxidant activity (significantly lower% inhibition value = 44.910 ± 3.597) both at a concentration of 500 mg·ml^?1, though all the millet extracts showed activity towards this assay better than the standard (19.883 ± 2.485%). Fonio millet extract displayed a significantly higher percentage inhibition of α-amylase and glucosidase (43.729 ± 0.410% and 55.835 ± 2.198%) than finger millet (39.002 ± 1.604%; 43.971 ± 5.849%) and pearl millet (33.223 ± 2.708%; 30.845 ± 2.841%), respectively.ConclusionThe polyphenolic extracts from these millet types have therapeutic potentials, which may play significant roles in type 2 diabetes prevention and management, and hence these millets, especially fonio and finger millet, have the potential to be utilized as functional foods.     

Patho-epidemiology of Cancer Corpus Uteri in Karachi South '1995-1997'.

Aim: To provide demographics and pathology of cancer of the uterine corpus in Karachi. Methodology: Data for 66 incident cases of cancer corpus uteri, ICD-10 category C54-5 registered at the Karachi Cancer Registry, for Karachi South, during a 3 year period, 1st January, 1995 to 31st December 1997 were reviewed. Results: Cancer uterine corpus (1995-97) was the sixth most common malignancy, following breast, oral cavity, ovary, esophagus and cervix. The age standardized incidence rate (ASR) world and crude incidence rate (CIR) per 100,000 were 6.4 (4.73 to 8.01) and 2.9 (2.18 to 3.57). The mean age was 53.7 years (SD 15.6; range 6-90 years). Fifty eight cases were endometrial carcinoma with ASR world and CIR per 100,000 of 5.77 (4.20 to 7.33) and 2.53 (1.88 to 3.18) respectively. Sarcomas comprised 6% of the cases. Approximately a third of the females (28.8%) were below 50 years of age. The age-specific curves showed a gradual increase from the fourth till the seventh decade, followed by an actual apparent decrease in risk after 70 years. Peak incidence was observed in the 65-69 year age group. Presenting symptoms were post-menopausal bleeding (86.4%) and purulent discharge (4%). Associated pathologies included adenomyosis, adenomatous hyperplasia (12% each) or leiomyoma (8%). Associated clinical conditions were diabetes mellitus and hypertension (4% each). The majority of the cases presented as well differentiated (39.4%), localized (59.1%) lesions. Conclusion: The incidence of cancer corpus uteri in Karachi South reflects a moderate risk population, predominantly middle aged with a higher socio-economic status. On the average the malignancy is observed a decade earlier then reported elsewhere. This calls for in-depth investigation of risk factors and identification of underlying etiology.     

Oral and written language abilities of XXY boys: implications for anticipatory guidance

Previous studies of XXY boys suggest that they are at risk for certain communication disorders involving oral and written language. In this study, the language, reading, and spelling skills of a group of 14 XXY boys identified during neonatal cytogenetic screening were compared with those of a group of 15 control children. The two groups were matched for age, grade, race, parity, birth weight, parental age and education, and socioeconomic status. The mean age of the XXY group was 9 years 7 months and that of the control group was 9 years 3 months. The mean academic grade level for both groups was at the transition between third and fourth grade. There was selective reduction in verbal IQ scores for the XXY group and no significant differences apparent between groups for performance IQ scores. The decrease in verbal IQ was associated with a reduced full-scale IQ and also with significant problems in expressive language, auditory processing abilities, and auditory memory. Word-finding difficulties and problems in the production of syntax were major components of the specific expressive language deficit. Except for difficulties in the understanding of complex sentence structures, the receptive language skills of XXY boys did not differ significantly from those of the control group. These reductions in speech and language abilities correlated with decreased achievement by the XXY group on a variety of reading and spelling tasks. These results suggest that difficulty learning how to read and spell may be due to a preexistent language disability. Early attention to such expressive language problems may be essential to ameliorate secondary maladaptive behaviors due to chronic language-related learning disabilities.     

Follow-up angiography of intracranial aneurysms treated with endovascular placement of Guglielmi detachable coils

OBJECTIVE: The success of endovascular treatment of intracranial aneurysms with Guglielmi detachable coils (GDCs) is dependent on the long-term exclusion of the aneurysm from the circulation. We reviewed our experience with the long-term angiographic follow-up monitoring of aneurysms that had been treated with GDCs. METHODS: All patients whose aneurysms had been treated with GDCs between January 1995 and August 1999 and who subsequently underwent follow-up angiography at 6 months or more were included in this study. We reviewed all of the angiographic findings, to determine the percentage of aneurysm occlusion on the initial angiograms and on the last available follow-up angiograms. The categories of aneurysm occlusion used were 100%, >or=95%, and less than 95% occlusion. RESULTS: One hundred thirty patients with 141 aneurysms underwent 143 endovascular coiling procedures and subsequently underwent angiographic follow-up monitoring of 6 months or more. There were 102 female and 28 male patients. The mean angiographic follow-up period was 16.7 months (range, 6-62 mo). The initial rates of occlusion were 100% for 56 aneurysms (39%), >or=95% for 65 aneurysms (46%), and less than 95% for 22 aneurysms (15%). Recurrence of one aneurysm (1.8%) was observed. Of the 87 aneurysms that were incompletely occluded initially, there was progressive thrombosis in 40 (46%), stable neck remnants in 23 (26%), and enlargement of the residual neck in 24 (28%). The final occlusion rates, determined on the last available angiograms, were 100% for 88 aneurysms (61%), >or=95% for 31 aneurysms (22%), and less than 95% for 24 aneurysms (17%). No patient experienced repeat or new subarachnoid hemorrhage more than 6 months after the initial treatment. CONCLUSION: Late angiographic follow-up monitoring of aneurysms that have been treated with GDCs demonstrates the durability of the treatment. Aneurysms with large residual neck remnants were subjected to further treatment, whereas aneurysms with small residual neck remnants remain under observation.

Two of the health care workers became secondary cases; one of them died on day 13 after coming in contact with the index case. The other secondary case was successfully treated with oral ribavirin.     

Anthropometric measurements of infants and under five children in Riyadh City

The data presented in this paper are part of the ongoing pediatric nutrition surveillance in ten primary health centers from Riyadh City. A total of 21,507 infants and children under five were included. The mean birth weight was 3027 g, and 8.6% of the children had low birth weights. The measurements showed that there had been no obvious change in the weights and heights of children during the past 13 years. In our results the children classified as moderate and severely underweight were 4.5% and 0.8% respectively. The data showed the average growth of all infants, regardless of feeding pattern, was same or faster than the NCHS reference population, up to approximately six months of age after which their growth became slower than that of the NCHS standards. The prevalence of malnutrition in Saudi Arabia is moderately high, in spite of the high per capita income, and the fact that the government subsidizes locally produced and imported food items. The malnutrition among this age group may be attributed to reproductive or social behavior and genetic factors. The reduction of malnutrition in the last ten years could be largely due to the nutrition and health education programs. There is a need for more comprehensive nutritional health education among the local population.     

Clinical and pathologic findings in hereditary spastic paraparesis with spastin mutation

OBJECTIVE: To describe a family with chromosome 2p-linked hereditary spastic paraparesis (HSP) associated with dementia and illustrate the cerebral pathology associated with this disorder. BACKGROUND: HSP comprises a heterogeneous group of inherited disorders in which the main clinical feature is severe, progressive lower limb spasticity. Nongenetic classification relies on characteristics such as mode of inheritance, age at onset, and the presence or absence of additional neurologic features. Several loci have been identified for autosomal dominant pure HSP. The most common form, which links to chromosome 2p (SPG4), has recently been shown to be due to mutations in spastin, the gene encoding a novel AAA-containing protein. RESULTS: The authors report four generations of a British family with autosomal dominant HSP in whom haplotype analysis indicates linkage to chromosome 2p. In addition, a missense mutation has been identified in exon 10 of the spastin gene (A1395G). Dementia was documented clinically in one member of the family, two other affected family members were reported to have had late onset memory loss, and a younger affected individual showed evidence of memory disturbance and learning difficulties. Autopsy of the demented patient confirmed changes in the spinal cord typical of HSP and also demonstrated specific cortical pathology. There was neuronal depletion and tau-immunoreactive neurofibrillary tangles in the hippocampus and tau-immunoreactive balloon cells were seen in the limbic and neocortex. The substantia nigra showed Lewy body formation. The pathologic findings are not typical of known tauopathies. CONCLUSIONS: The authors confirm that chromosome 2p-linked HSP can be associated with dementia and that this phenotype may be associated with a specific and unusual cortical pathology.
