Secondary xylary features in proving truth/falsity of an alibi: examples of three important Indian commercial woods
Secondary xylary characters of wood are useful to identify a wood up to its generic or specific level and thus may prove or disprove the alibi of the retailers i.e., a wood is genuine or not. In the present study, 26 wood samples were collected from the local markets of Baruipur, Sealdah and Garia in Kolkata, West Bengal. Among them, 8 were sold as ‘Sandal wood’ (Santalum album), 4 as ‘Red Sanders’ (Pterocarpus santalinus) and 14 as ‘Sal wood’ (Shorea robusta). Results indicate that xylotomical features of most of the collected ‘sandal wood’ and ‘red sander’ samples did not match with the reference Santalum album and Pterocarpus santalinus samples whereas most of the collected ‘Sal wood’ samples from furniture shops matched with the reference samples of Shorea robusta. Present study successfully indicates that xylotomical investigations of commercial wood may establish the authenticity of wood of commerce
Taxonomic studies of Eulophid parasitoids (Hymenoptera: Chalcidoidea) collected from Uttarakhand, India
A sound taxonomic knowledge base is a prerequisite for effective conservation, environment assessment, ecological research, management and sustainable use of biological resources. Parasitoids are the major component of the biocontrol, so the correct identification of the parasitoid is very important task. Eulophidae is a large family of the superfamily Chalcidoidea and comprises promising biocontrol agents for the control of insect pests causing harm to agricultural ecosystem. The present study has been done to provide the account and occurrence of 4 genera belonging to subfamily Entedoninae, Eulophinae and Tetrastichinae. Entedon costalis Dalman, Diglyphus horticola Khan, Hemiptarsenus varicornis (Girault), and Neotrichoporoides viridimaculatus (Fullaway) was collected from Uttarakhand (India) and described in detail with additional morphological characters that aids in clear identification of the parasitoids. Entedon costalis is recorded from this region with additional characters for identification
Anthocyanins: Plant-based flavonoid pigments with diverse biological activities
Anthocyanins are flavonoid containing polyphenolic phytochemicals. They are widely present in plants and accounts for different color shades displayed by the plant organs. A broad range of health-revitalizing effects is attributed to anthocyanins, constituting a vital part of the human diet. They are also accountable for ameliorating the detrimental effects of various lifestyle diseases, including cancer, cardiovascular disorders, neurological disorders, etc. These beneficial impacts highly depend on the bioavailability of anthocyanins, governed by their absorption and metabolism in the human body. The primary goal of this review is to summarize the latest anthocyanin knowledge while focusing on the chemistry, pharmacokinetics, and various biological advantages with anti-cancer, neuroprotective, antidiabetic, antioxidant, cardiovascular protective, vision improvement, antiviral, and antimicrobial effects
STUDY OF LOCOMOTOR DISABILITY DUE TO VARIOUS TYPES OF TRAUMA
Background: Many people in the world live with different disabilities. Among various types of disability locomotor disability is one of the major types. Trauma is important cause of locomotor disability and in India it is second most common cause of locomotor disability. There is insufficient data available in India to determine contribution of trauma to loco motor disability. This study is required for the same so as to know the extent of problem of disability in Indian society.
Materials and Methods: All the patients attending the out-patient department of institute were examined after taking verbal consent.Patients having locomotor disability were included in this study.
Results: In our study persons having traumatic permanent locomotor disability were found to be 524 among total 3500 locomotor disabled persons attending our institute. Total numbers of new patients attending our institute were 11990 during study period. The prevalence of locomotor disability was 29.19% (3500) out of total 11990 patients attended this institute. The prevalence of traumatic permanent locomotor disability was 14.97% (524), among all (3500) locomotor disabled patients.The cause of disability in 41.8% was railway accidents, 41.6 % was due to road traffic accidents,12.2% due to machine injuries, 4% due to fall, 0.2% due to bullet injuries, 0.2% due to sports injuries. . It was observed that 85.1% (446) out of 524 are males and 14.9% (78) out of 524 are females having locomotor disability due to trauma.
Conclusion: Trauma contributes not only to significant number of disabilities, but also to severity of disability. Road traffic accidents and railway accidents are major causes of traumatic locomotor disability and young persons are the usual victims of such disasters
Exploring the therapeutic opportunities of potassium channels for the treatment of rheumatoid arthritis
Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that affects the synovial joint, which leads to inflammation, loss of function, joint destruction, and disability. The disease biology of RA involves complex interactions between genetic and environmental factors and is strongly associated with various immune cells, and each of the cell types contributes differently to disease pathogenesis. Several immunomodulatory molecules, such as cytokines, are secreted from the immune cells and intervene in the pathogenesis of RA. In immune cells, membrane proteins such as ion channels and transporters mediate the transport of charged ions to regulate intracellular signaling pathways. Ion channels control the membrane potential and effector functions such as cytotoxic activity. Moreover, clinical studies investigating patients with mutations and alterations in ion channels and transporters revealed their importance in effective immune responses. Recent studies have shown that voltage-gated potassium channels and calcium-activated potassium channels and their subtypes are involved in the regulation of immune cells and RA. Due to the role of these channels in the pathogenesis of RA and from multiple pieces of clinical evidence, they can be considered therapeutic targets for the treatment of RA. Here, we describe the role of voltage-gated and calcium-activated potassium channels and their subtypes in RA and their pharmacological application as drug targets
PLC (ARDUINO) BASED SELF-SUSTAINING HYDROPONIC FODDER SYSTEM
In India only 4.9 % of cropped land area is utilized for cultivating fodder. India faces a deficit of 35.6% green fodder, 26% of dry fodder and 41% of concentrate feed ingredients.So our goal in this project is to develop a self-sustaining fodder system using basic PLC circuits and to operate it on renewable energy. Which in result will reduce the energy requirement, cost of production per kg, water and land requirements to operate the system along with the readyavailability of green fodder and negligible human interference
Depositional Environment of Mio-Pliocene Siwalik Sedimentary Strata from the Darjeeling Himalayan Foothills, India: A Palynological Approach.
A rich and diverse palynoassemblage recovered from the Churanthi River section (26°53' 59.3" N, 88°34' 17.2" E), Darjeeling foothills Eastern Himalaya, has yielded 87 species assigned to 69 genera. The palynoassemblage is rich in angiosperm taxa (45.63%) followed by gymnosperms (0.45%), pteridophytes (18.49%) and fungal remains (23.88%). Based on their nearest living relatives, a wet evergreen to semi-evergreen forest under a humid tropical to sub-tropical environment during the Mio-Pliocene age has been suggested. A lot of angiosperms such as Palaeosantalaceaepites, Araliaceoipollenites, Malvacearampollis, Zonocostites, Neocouperipollis, Dicolpopollis, Palmidites, Palmaepollenites, isolated salt glands of mangrove plant leaves (Heliospermopsis) and Mediaverrunites type of fungal spores, along with ichnofossils like Planolites, Palaeophycus, Skolithos, Rosselia, Ophiomorpha and Teichichnus associated with rippled mudstone-siltstone suggest an environment strongly influenced by brackish water. Primary sedimentary structures in the associated strata indicate strong wave agitation common in shallow marine setting. Some high elevation components (5.14%) such as Alnipollenites, cf. Corylus (Betulaceae), Juglanspollenites, Engelhardtioipollenites (Juglandaceae), Quercoides, Cupuliferoidaepollenites, Lithocarpus, Castanopsis (Fagaceae), Abietineaepollenites (Pinaceae) represent hinterland vegetation possibly transported to the prograding deltaic coastline by the rivers. Reworked palynotaxa (Striatopodocarpites sp., Striatites sp., Faunipollenites sp., Circumstriatites sp., Crescentipollenites sp., Cuneatisporites sp., Parasaccites sp., Scheuringipollenites sp., Rhizomaspora sp., Marsupipollenites sp., Lophotriletes sp.) of Permian age have also been recorded in the palynoassemblage (11.55%) indicating the abundance of Permian Gondwana strata in the source area
