Storage influence on the functional, sensory and keeping quality of quality protein maize flour. - Journal of food science and technology
Apart from nutritional values functional and sensory properties affect the behavior of food system and its acceptability for consumption during storage. Hence keeping quality of maize flour (HQPM-7) with and without lime treatment(control) was studied in terms of functional (bulk density, pH, swelling capacity, water and oil absorption capacity, least gelation concentration, peroxide value), sensory (appearance, color, taste, texture, mouth feel and overall acceptability) and rolling parameters (water absorption by flour, rolling quality, diameter after baking ) for a period of 6Â months under room temperature (25â€‰Â±â€‰5Â Â°C) in two types of packages viz, LDPE cover (P) and plastic box (B). Physical parameters such as length, breadth and thickness (11.26-10.52Â mm, 9.67-9.14Â mm, & 4.72-3.95Â mm) were reduced in lime treated grains compared to control. Significant increase (pâ€‰â‰¤â€‰0.05) in ash content of lime treated flour (1.67â€‰Â±â€‰0.01Â g) was observed compared to control (1.5â€‰Â±â€‰0.02Â g). Calcium content of lime treated maize flour increased significantly (pâ€‰â‰¤â€‰0.05) from 48 to 136Â mg. There is a significant reduction in functional properties of flour after 3 and 2Â months irrespective in polyethylene cover and plastic box. The properties like rolling quality, diameter after baking and water uptake by the flour were reduced significantly (pâ€‰â‰¤â€‰0.05) after 4Â months of storage in treated and after 1Â month in control samples. Sensory scores of roti (dry pan cake) decreased significantly after 3Â months of storage with an overall acceptability score of 4.0 and 3.4. In control samples mean taste (3.6), mouth feel (3.8) as well as OAA scores (3.8) decreased after second month. Hence lime treated maize flour with added nutritional benefits is suitable for making rotis of good palatability and can be stored in LDPE covers up to 3Â months.
Biodegradation of 2,4'-dichlorobiphenyl, a congener of polychlorinated biphenyl, by Pseudomonas isolates GSa and GSb. - Indian journal of experimental biology
Bioegradation of 2,4'-dichlorobiphenyl (2,4 CB), by two isolates of Pseudomonas (GSa and GSb) was compared using GC-MS. Transformer oil polluted soil was used for the isolation of 2,4 CB degrading bacteria. GC-MS analysis of the solvent extracts obtained from Pseudomonas sp. GSa spent culture indicated the presence of Phenol 2,6-bis (1,1-dimethyl)-4-methyl (C15H24O). Further, the enzyme analysis of the cell free extracts showed the presence of 2,4'-dichlorobiphenyl dehalogenase (CBD), 2,4'-dichlorobiphenyl-NADPH-oxido-reductase (2,4 CBOR) and 2,3-dihydroxybiphenyl-NADPH-oxido-reductase (2,3 DHOR) with specific activity of 6.00, 0.4 and 0.22 pmol/min/mg of protein, suggesting that dechlorination as an important step during 2,4 CB catabolism. Further, the cell free extract of GSb showed only 2,4'-dichlorobiphenyl-NADPH-oxido-reductase (2,4 CBOR) and 2,3-dihydroxybiphenyl-NADPH-oxido-reductase (2,3 DHOR), with specific activity of 0.3 and 0.213 Î¼mol/min/mg of protein, suggesting attack on non-chlorinated aromatic ring of 2,4 CB, releasing chlorinated intermediates which are toxic to the environment. Although, both the isolated bacteria (GSa and GSb) belong to Pseudomonas spp., they exhibited different metabolic potential.
Sinonasal hemangiopericytoma: A rare case report with review of literature. - Journal of oral and maxillofacial pathology : JOMFP
Hemangiopericytoma (HPC) is a rare tumor of uncertain malignant potential. Stout and Murray described HPC as "vascular tumor arising from Zimmerman's pericyte" in 1942. The World Health Organization (WHO) reclassified HPC as a fibroblastic/myofibroblastic tumor, after further characterization. HPC is found mostly wherever there is increased vascularity seen. The incidence of the tumor in head and neck area is only 15%, mostly seen in adults. We report here a case of HPC of a 22-year-old female, who presented to our department with a tender swelling in maxillary anterior region and the mass was well-circumscribed, sessile and soft on palpation. The skin over the tumor was intact and normal. The tumor was completely removed with wide surgical resection. The histopathological staining supported the diagnosis of HPC, this was further confirmed by immunohistochemistry (IHC) in which CD99 showed strong positivity.
Awareness of the association between periodontal disease and adverse pregnancy outcome among the general female population. - Indian journal of dental research : official publication of Indian Society for Dental Research
Preterm low birth weight (PTLBW) is a public health issue which needs to be dealt with by educating the general female population. One of the major contributing factors is periodontal disease and treatment of the same could reduce the occurrence of PTLBW babies. Therefore, awareness of this among the female population is highly essential. Hence, this survey was planned with the aim to explore the awareness of the general female population regarding the association of periodontal disease and PTLBW.This survey consisted of nine close-ended questions answered by 1284 females.Younger individuals had higher knowledge scores as compared to the older individuals (r = -0.161) and the more educated group had a higher knowledge score as compared to the less educated groups (r = 0.322). Furthermore, married women seemed to be more aware of the relation of PTLBW to periodontal disease as compared to unmarried women.Younger and educated females had better awareness of the association between periodontal diseases and PTLBW. Hence, efforts to educate the general female population on this association could contribute toward the reduction of the risk of PTLBW.
Post-traumatic Stress Disorder in Facial Injuries: A Comparative Study. - The journal of contemporary dental practice
The aim of the study was to identify the presence of post-traumatic stress disorder (PTSD) in patients who had sustained facial injuries, additionally, we aimed to identify other variables that may modify the psychological response to trauma that include gender, age and presence of disfigurement post-treatment and visible scars/orthopedic injuries.Participants comprised of 460 patients from several multinodal trauma centers in Bengaluru City, Karnataka, who had sustained facial injuries that had healed either with or without significant disfigurement or scarring and with visible/orthopedic injuries. One hundred and eleven patients of the chosen 460 had sustained nondisfiguring facial injuries while 153 patients sustained disfiguring facial injuries, 64 patients who sustained facial injury (i.e. 19.5%) were lost to follow-up and were not included in the study. One hundred and thirty-two had sustained orthopedic/visible injuries; however, in this group, 18 (i.e. 13.6%) patients were lost to follow-up and were excluded from the study. The impact of events scale (IES) was used to check the presence of PTSD.Statistically significant higher means of IES were present in patients with disfiguring facial injuries compared to nondisfiguring facial injuries, female patients compared to male patients, patients with disfiguring facial injuries compared to orthopedic/visible injuries and patients who were younger than 50 years of age compared to patients who were older than 50 years of age and the results observed were similar at all three study intervals (date of discharge (DOD), 1 month and 6 months postoperatively).Patients with disfiguring facial injuries had significantly higher PTSD levels compared to patients with nondisfiguring facial injuries, patients with orthopedic/visible injuries had statistically significant lower IES scores which could not be strictly termed PTSD when compared to patients with disfiguring facial injuries who had high scores of IES corresponding to high levels of PTSD and these results were observed at all three study intervals (DOD, 1 and 6 months postoperatively). Female patients with disfiguring facial injuries had significantly higher PTSD levels compared to male patients (at all the study intervals) and patients younger than 50 years of age had significantly higher PTSD levels compared to older patients.
Primary peritoneal carcinoma: regional cancer institute experience. - Indian journal of surgical oncology
Primary peritoneal serous carcinoma (PPSC) is a rare malignancy that arises primarily from peritoneal surface epithelium. However there are limited studies on these tumors even in world literature. To study the clinical, pathologic profile, outcome and prognostic features of PPSC. A 5Â year retrospective study of PPSC diagnosed and treated at our centre was conducted. The pathological specimen of PPSC diagnosed from January 2008 to December 2012 were reviewed by gynaeconcopathologists. The diagnosis was based on GOG criteria, complemented with IHC. Majority of the patients underwent upfront de-bulking surgery. Postoperatively, six cycles of combination chemotherapy with paclitaxel (175Â mg/m(2)) and carboplatin (AUC 6) was administered every 3 weekly. These patients were analysed for progression free survival (PFS), this was correlated with stage and surgical adequacy. The median age of presentation was 56Â years. The total number of ovarian cancers treated during study period was 374. The 30 cases were clinically suspected to have primary peritoneal carcinoma (PPC) on pre- and intra-operatve gross findings, but further evaluation with histopathological examination, IHC and GOG criteria revealed only 10 cases were genuine PPSC. The remaing 20 cases; 13 were found to poorly differentiated ovarian carcinomas, six were primary fallopian tube carcinoma and one was appendicular carcinoma. The 10 (2.7Â %) cases of the 374 were eligible for the PPSC analysis. The two (20Â %) of the 10 cases had family history of breast and ovarian cancers, two (20Â %) cases were diagnosed as abdominal tuberculosis (TB) prior referral to our centre. Radiological presentation includes gross ascites, with omental caking and normal adenexa. The eight (80Â %) of 10 cases presented with stage IIIC and other two cases (20Â %) with stage IV disease. The eight (80Â %) of 10 cases underwent upfront surgery; six (75Â %) of these eight cases had optimal cytoreduction, i.e. residual disease (RD) <1Â cm or no visible disease (R0) and other two (25Â %) suboptimal cytoreduction. The two (20Â %) of 10 cases with stage IV disease received neoadjuvant chemotherapy (NACT) followed by interval cytoreduction. After debulking surgery the most useful IHC marker include CK7+, CK20-, CA125+, WT-1+, and GCDFP- . At median follow up of 24Â months (range 3-60Â months), the median progression free survival (PFS) was 22Â months, while the estimated 5Â year PFS was 18Â %. Stage IV disease and suboptimal surgery had poor outcome. The PPSC presents with advanced stage disease and are observed to be misdiagnosed abdominal TB in tropical countries. The GOG criteria and IHC complement the diagnosis. These have poor outcome despite optimal care, highlighting need for larger studies on this disease.
Utilization of extrusion technology for the development of millet based complementary foods. - Journal of food science and technology
Millet based complementary foods were developed using sorghum (Sorghum vulgare), rice (Oryza Sativa), besan (Cicer arietinum; Bengal gram dhal flour), legume mix (Green gram and roasted Bengal gram; Phaseolus aureus Roxb and Cicer arietinum) and soybean (Glycine max Merr) with a lab scale twin screw extruder. The extrudates were subjected to acceptability studies initially and at the end of the storage period i.e. 3Â months at laboratory level by panel of judges using a 5-point hedonic scale. Physico-chemical characteristics like bulk density, piece density and expansion ratio were measured and proximate principles were assessed. Soy and legume mix were found to have low bulk density as well as high expansion ratio. The developed extrudates were made into fine powder and sieved through a 60Â mm mesh. Malted ragi flour at 15Â % level was added to the powdered extrudates to develop the complementary mixes with low bulk density. Raw formulas without malt and with malt; extruded mixes without malt and with malt were studied for viscosity. The developed mixes were made into porridge and fed to the infants and the opinions about the acceptability of mixes were collected from the mothers. The complementary mixes with malted ragi showed reduced viscosity and formed good, smooth slurry and well accepted both by children and their mothers. Extruded soy and legume mixes with addition of 15Â % malt were found to have satisfactory functional characteristics and nutritive value and can be explored for bulk preparation.
Musculoskeletal disorders in sickle cell anaemia--unusual associations. - The Journal of the Association of Physicians of India
Sickle cell anaemia coexisting with gout is a rare clinical association, as is gout and eosinophilia. This report records the second case of chronic tophaceous deposits in Sickle cell anaemia. The patient also had eosinophilia in association with gout. Skeletal fluorosis was an incidental finding in this patient. Treatment with packed cell transfusions, hydroxyurea and colchicine lead to the resolution of anaemia and symptoms of acute gout.
Effects of aging on the association between cerebrovascular responses to visual stimulation, hypercapnia and arterial stiffness. - Frontiers in physiology
Aging is associated with decreased vascular compliance and diminished neurovascular- and hypercapnia-evoked cerebral blood flow (CBF) responses. However, the interplay between arterial stiffness and reduced CBF responses is poorly understood. It was hypothesized that increased cerebral arterial stiffness is associated with reduced evoked responses to both, a flashing checkerboard visual stimulation (i.e., neurovascular coupling), and hypercapnia. To test this hypothesis, 20 older (64 Â± 8 year; mean Â± SD) and 10 young (30 Â± 5 year) subjects underwent a visual stimulation (VS) and a hypercapnic test. Blood velocity through the posterior (PCA) and middle cerebral (MCA) arteries was measured concurrently using transcranial Doppler ultrasound (TCD). Cerebral and systemic vascular stiffness were calculated from the cerebral blood velocity and systemic blood pressure waveforms, respectively. Cerebrovascular (MCA: young = 76 Â± 15%, older = 98 Â± 19%, p = 0.004; PCA: young = 80 Â± 16%, older = 106 Â± 17%, p < 0.001) and systemic (young = 59 Â± 9% and older = 80 Â± 9%, p < 0.001) augmentation indices (AI) were higher in the older group. CBF responses to VS (PCA: p < 0.026) and hypercapnia (PCA: p = 0.018; MCA: p = 0.042) were lower in the older group. A curvilinear model fitted to cerebral AI and age showed AI increases until ~60 years of age, after which the increase levels off (PCA: R (2) = 0.45, p < 0.001; MCA: R (2) = 0.31, p < 0.001). Finally, MCA, but not PCA, hypercapnic reactivity was inversely related to cerebral AI (MCA: R (2) = 0.28, p = 0.002; PCA: R (2) = 0.10, p = 0.104). A similar inverse relationship was not observed with the PCA blood flow response to VS (R (2) = 0.06, p = 0.174). In conclusion, older subjects had reduced neurovascular- and hypercapnia-mediated CBF responses. Furthermore, lower hypercapnia-mediated blood flow responses through the MCA were associated with increased vascular stiffness. These findings suggest the reduced hypercapnia-evoked CBF responses through the MCA, in older individuals may be secondary to vascular stiffening.
Dietary pattern of schoolgoing adolescents in urban Baroda, India. - Journal of health, population, and nutrition
Diet plays a very important role in growth and development of adolescents, during which the development of healthy eating habits is of supreme importance. There is a dual burden of undernutrition and overnutrition in this age-group. The study assessed the food habits, food preferences, and dietary pattern of schoolgoing urban adolescents in Baroda, India. Both quantitative and qualitative methods were used in this study. A quantitative survey was carried out using a pre-tested self-administered structured questionnaire among 1,440 students from class 6 to 12 in 7 English medium and 23 Gujarati medium schools. Focus group discussions, 5 each with adolescent boys and girls, were held, along with 5 focus group discussions with teachers of Gujarati and English medium schools. Nearly 80% of adolescents had consumed regular food, like dal, rice, chapati, and vegetables, including green leafy vegetables. Nearly 50% of them had consumed chocolates, and about one-third consumed fast foods. Nearly 60% of adolescents had their breakfast daily while the remaining missed taking breakfast daily. Nearly one-third of adolescents were missing a meal once or twice a week. A large majority had consumed regular foods. However, more than half of them had consumed chocolates, soft drinks, and over one-third had taken fast foods.
