From Bean to Bombay Mix

A snack known to the western world as Bombay Mix is now ubiquitous in India and the world. Their addictive taste and simplicity of ingredients appeal across class and caste. Curiously, Bombay Mix is originally a regional delicacy from the deserts of Rajasthan and thrives in India’s regional kitchens with vernacular renditions, spices and names. Noodly bhujia and beady boondis are made of Bengal gram, a variant of C.arietinum L. and moth bean, V.aconitifolia, unique to the subcontinent are mixed in various proportions and spices to make namkeen, literally savoury. Today, these snacks are mostly made from imported tepary beans, potato flour, cornflour, fried in palm oil and a repository of ingredients facilitated by large scale production and fuelled by popularity. These protein rich snacks have become commoditized, reduced to a singular denomination as Bombay Mix. This paper presents how a hyper local snack found its way across regional and international borders and moved beyond its original food systems and turned into a global Big Food industry

A comparative study to assess drinking expectancy and functioning in alcohol dependent patients with and without co-morbid depression

Background: Alcohol dependence syndrome (ADS) and major depressive disorder are highly prevalent. Much less is known about the expectancy of alcohol use in depressed patients with ADS. Few studies had compared the expectancy of alcohol use in ADS patients with and without co-morbid depression. Assessing the above factors may help to formulate effective prevention strategies. This study was designed to assess the difference in expectancy of alcohol use and functioning in patients with ADS with and without co-morbid depression.Methods: The difference in expectancy of alcohol use in 96 alcohol dependent patients, of which 24 had co-morbid depression and 72 without co-morbid depression was studied using drinking expectancy questionnaire. In addition, we compared the difference in functioning between the two groups using GAF.Results: Prevalence of depression in alcohol dependent patients was 25%. ADS patients with co-morbid depression had less expectancy about alcohol use for sexual enhancement and had lower level of functioning compared to ADS patients without depression.Conclusions: Less expectancy on sexual enhancement in patients with ADS and co-morbid depression could be possibly due to reduced libido in depressed patients. The observed lower functioning in ADS patients with co-morbid depression despite no difference in severity of alcohol use may be possibly explained by the added burden of both the diseases

Pattern of alcohol use and drinking antecedents in alcohol dependent patients with and without co-morbid depression: a comparative study

Background: Few studies have compared the pattern of alcohol use in Alcohol dependence syndrome (ADS) patients with and without co-morbid depression. Assessing the pattern may throw light into prevention of relapses more effectively in alcohol dependent patients with co-morbid depression. This study was undertaken to assess the difference in pattern of drinking of alcohol in patients with alcohol dependence with and without co-morbid depression.Methods: A descriptive comparative study was designed to compare the difference in pattern of alcohol use in alcohol dependent patients with co-morbid depression and without co-morbid depression. Severity of dependence on alcohol was assessed using Alcohol Use Disorders Identification Test (AUDIT). Drinking pattern was assessed using Timeline Follow back Calender and Drinking Pattern Questionnaire. The data were statistically analysed.Results: Total 96 alcohol dependent patients (24 had co-morbid depression and 72 without co-morbid depression) were included in the study. There were no significant differences in alcohol use in both the groups in terms of AUDIT scores, amount of drinking, abstinence days or binge drinking. More frequent drinking was observed in circumstances related to emotional, physiological, financial and children related situations in patients with co-morbid depression (p<0.05).Conclusions: Drinking circumstances like emotional, physiological, financial and children related situations require more attention while assessing, treating and aiming at relapse of prevention in ADS patients with co-morbid depression

Outcome of three dimensional osteotomy for cubitus varus deformity

Background: Cubitus varus is the most common angular deformity resulting from supracondylar fracture of the humerus in children and adults. There are several options for correcting this deformity, but three dimensional osteotomy is now a popular method for the operative treatment of cubitus varus deformity. Objective of current study was to evaluate clinical and radiological outcome of three dimensional corrective osteotmy for cubitus varus deformity.Methods: This prospective interventional study was conducted in the department of orthopaedic surgery, BSMMU, Shahbag, Dhaka from January 2016 to September 2020. Within this period, total 40 cases of cubitus varus deformity, age ranging from 8-20 years that has the inclusion criteria was enrolled as a study sample with proper consent. All the data were analyzed statistically by using SPSS-22.Results: The results of present study showed significantly improved carrying angle, range of motion, internal rotation angle at the time of final follow-up period of six months or more. The outcome of the subjects was graded as excellent in 16 (40%), good in 18 (45%), fair in 4 (10%) and poor in 2 (5%) patients. Excellent, good and fair results were considered as satisfactory outcome and only poor result was considered as unsatisfactory outcome.Conclusions: After analyzing the results of present study it can be concluded that three dimensional osteotomy is a safe technique with satisfactory outcome in treatment of cubitus varus deformity

Efficacy of expressed breast milk alone or in combination with paracetamol in reducing pain during retinopathy of prematurity screening: A randomized controlled trial

Background: The aim of this study was to determine the efficacy of expressed breast milk (EBM) alone or in combination with oral paracetamol for pain reduction during retinopathy of prematurity (ROP) screening.  Methods: A randomized control trial was conducted in two departments of Bangabandhu Sheikh Mujib Medical University. A total of 60 preterm neonates who underwent ROP screening were randomized into three equal groups. Group A got nesting and swaddling as per institutional protocol (control). Group B received 2 ml EBM two minutes prior to the ROP screening and Group C received 15 mg/kg syrup paracetamol 30 minutes prior to the ROP screening and EBM like Group B. Premature infant pain profile (PIPP) scores was used prior, during and 2 minutes after ROP screening procedure. Results: The three groups were similar in terms of baseline characteristics. The mean (standard deviation) PIPP scores during the procedure were 16.4 (1.1), 15.0 (1.8) and 13.4 (1.8) in control, EBM, and EBM with paracetamol groups respectively. The PIPP scores were significantly lower in the EBM and EBM with paracetamol groups during the procedure compared to control group. In the EBM and EBM with paracetamol groups, the mean difference in PIPP scores (between before and during the procedure) was also substantially lower. Conclusion: Breast milk alone or in combination with paracetamol can reduce significant pain during ROP screening than control group.

Expressing OsiSAP8, a Zinc-Finger Associated Protein Gene, Mitigates Stress Dynamics in Existing Elite Rice Varieties of the 'Green Revolution'

Key message: Overexpression of OsiSAP8 driven by Port Ubi2.3 from Porteresia coarctata imparts drought and salinity stress tolerance in transgenic rice. Stress associated proteins (SAPs) possess the zinc-finger domains that are wildly evolving functional and conserved regions/factors in plants to combat abiotic stresses. In this study, the promoter region of OsiSAP8, an intron-less, multiple stress inducible gene, was compared in silico with a strong constitutive promoter, Port Ubi2.3. This resulted in developing rice, resistant to drought and salinity expressing OsiSAP8 promoted by Port Ubi2.3. (Porteresia coarctata), through Agrobacterium-mediated transformation in the popular rice varieties, IR36 and IR64. Southern blot hybridization confirmed the integration of OsiSAP8, and the T0 transgenic lines of IR36 and IR64 were evaluated for their drought and salinity tolerance. The IR36-T1 progenies showed an enhanced tolerance to water withhold stress compared to wild type and IR64-T1 progenies. Physiological parameters, such as the panicle weight, number of panicles, leaf wilting, and TBARS assay, showed the transgenic IR36 to be superior. The transgenic lines performed better with higher 80-95% relative leaf water content when subjected to drought for 14 days. Gene expression analysis of OsiSAP8 in IR36 T1 showed a 1.5-fold upregulation under mannitol stress. However, IR64 T1 showed a two-fold upregulation in NaCl stress. An enhanced drought and salinity stress tolerance in the transgenic IR36 cultivar through overexpression of OsiSAP8 was observed as it had a native copy of OsiSAP8. This is perhaps the first study using a novel ubiquitin promoter (Port Ubi2.3) to generate drought and salinity stress-tolerant transgenic rice. Thus, we report the overexpression of a rice gene (OsiSAP8) by a rice promoter (Port Ubi2.3) in rice (IR36) to resist drought and salinity

Corneal nerve and brain imaging in mild cognitive impairment and dementia

Background: Visual rating of medial temporal lobe atrophy (MTA) is an accepted structural neuroimaging marker of Alzheimer's disease. Corneal confocal microscopy (CCM) is a non-invasive ophthalmic technique that detects neuronal loss in peripheral and central neurodegenerative disorders. Objective: To determine the diagnostic accuracy of CCM for mild cognitive impairment (MCI) and dementia compared to medial temporal lobe atrophy (MTA) rating on MRI. Methods: Subjects aged 60-85 with no cognitive impairment (NCI), MCI, and dementia based on the ICD-10 criteria were recruited. Subjects underwent cognitive screening, CCM, and MTA rating on MRI. Results: 182 subjects with NCI (n = 36), MCI (n = 80), and dementia (n = 66), including AD (n = 19, 28.8%), VaD (n = 13, 19.7%), and mixed AD (n = 34, 51.5%) were studied. CCM showed a progressive reduction in corneal nerve fiber density (CNFD, fibers/mm2) (32.0±7.5 versus 24.5±9.6 and 20.8±9.3, p < 0.0001), branch density (CNBD, branches/mm2) (90.9±46.5 versus 59.3±35.7 and 53.9±38.7, p < 0.0001), and fiber length (CNFL, mm/mm2) (22.9±6.1 versus 17.2±6.5 and 15.8±7.4, p < 0.0001) in subjects with MCI and dementia compared to NCI. The area under the ROC curve (95% CI) for the diagnostic accuracy of CNFD, CNBD, CNFL compared to MTA-right and MTA-left for MCI was 78% (67-90%), 82% (72-92%), 86% (77-95%) versus 53% (36-69%) and 40% (25-55%), respectively, and for dementia it was 85% (76-94%), 84% (75-93%), 85% (76-94%) versus 86% (76-96%) and 82% (72-92%), respectively. Conclusion: The diagnostic accuracy of CCM, a non-invasive ophthalmic biomarker of neurodegeneration, was high and comparable with MTA rating for dementia but was superior to MTA rating for MCI

Association of Cerebral Ischemia With Corneal Nerve Loss and Brain Atrophy in MCI and Dementia

IntroductionThis study assessed the association of cerebral ischemia with neurodegeneration in mild cognitive impairment (MCI) and dementia.MethodsSubjects with MCI, dementia and controls underwent assessment of cognitive function, severity of brain ischemia, MRI brain volumetry and corneal confocal microscopy.ResultsOf 63 subjects with MCI (n = 44) and dementia (n = 19), 11 had no ischemia, 32 had subcortical ischemia and 20 had both subcortical and cortical ischemia. Brain volume and corneal nerve measures were comparable between subjects with subcortical ischemia and no ischemia. However, subjects with subcortical and cortical ischemia had a lower hippocampal volume (P &lt; 0.01), corneal nerve fiber length (P &lt; 0.05) and larger ventricular volume (P &lt; 0.05) compared to those with subcortical ischemia and lower corneal nerve fiber density (P &lt; 0.05) compared to those without ischemia.DiscussionCerebral ischemia was associated with cognitive impairment, brain atrophy and corneal nerve loss in MCI and dementia

The genetic architecture of membranous nephropathy and its potential to improve non-invasive diagnosis

Membranous Nephropathy (MN) is a rare autoimmune cause of kidney failure. Here we report a genome-wide association study (GWAS) for primary MN in 3,782 cases and 9,038 controls of East Asian and European ancestries. We discover two previously unreported loci, NFKB1 (rs230540, OR = 1.25, P = 3.4 × 10-12) and IRF4 (rs9405192, OR = 1.29, P = 1.4 × 10-14), fine-map the PLA2R1 locus (rs17831251, OR = 2.25, P = 4.7 × 10-103) and report ancestry-specific effects of three classical HLA alleles: DRB1*1501 in East Asians (OR = 3.81, P = 2.0 × 10-49), DQA1*0501 in Europeans (OR = 2.88, P = 5.7 × 10-93), and DRB1*0301 in both ethnicities (OR = 3.50, P = 9.2 × 10-23 and OR = 3.39, P = 5.2 × 10-82, respectively). GWAS loci explain 32% of disease risk in East Asians and 25% in Europeans, and correctly re-classify 20-37% of the cases in validation cohorts that are antibody-negative by the serum anti-PLA2R ELISA diagnostic test. Our findings highlight an unusual genetic architecture of MN, with four loci and their interactions accounting for nearly one-third of the disease risk

Approaches in biotechnological applications of natural polymers

Natural polymers, such as gums and mucilage, are biocompatible, cheap, easily available and non-toxic materials of native origin. These polymers are increasingly preferred over synthetic materials for industrial applications due to their intrinsic properties, as well as they are considered alternative sources of raw materials since they present characteristics of sustainability, biodegradability and biosafety. As definition, gums and mucilages are polysaccharides or complex carbohydrates consisting of one or more monosaccharides or their derivatives linked in bewildering variety of linkages and structures. Natural gums are considered polysaccharides naturally occurring in varieties of plant seeds and exudates, tree or shrub exudates, seaweed extracts, fungi, bacteria, and animal sources. Water-soluble gums, also known as hydrocolloids, are considered exudates and are pathological products; therefore, they do not form a part of cell wall. On the other hand, mucilages are part of cell and physiological products. It is important to highlight that gums represent the largest amounts of polymer materials derived from plants. Gums have enormously large and broad applications in both food and non-food industries, being commonly used as thickening, binding, emulsifying, suspending, stabilizing agents and matrices for drug release in pharmaceutical and cosmetic industries. In the food industry, their gelling properties and the ability to mold edible films and coatings are extensively studied. The use of gums depends on the intrinsic properties that they provide, often at costs below those of synthetic polymers. For upgrading the value of gums, they are being processed into various forms, including the most recent nanomaterials, for various biotechnological applications. Thus, the main natural polymers including galactomannans, cellulose, chitin, agar, carrageenan, alginate, cashew gum, pectin and starch, in addition to the current researches about them are reviewed in this article.. }To the Conselho Nacional de Desenvolvimento Cientfíico e Tecnológico (CNPq) for fellowships (LCBBC and MGCC) and the Coordenação de Aperfeiçoamento de Pessoal de Nvíel Superior (CAPES) (PBSA).
