Paddy, Tubers, Honey, Toddy in Sangam Tamil Food

People can survive even without clothes and shelter, which are the basic things that people need. But we cannot survive without food. So food was man's first quest. Fruits. Early vegetable man may have gradually learned to cook and cultivate food. Humans who started cooking food and made various changes in food later came to know indigenous cuisines as well. The types of food that a country can eat depends on its climate and climate. Diets have also varied according to economic ups and downs. A lot of Tamil literature deals with the food of Tamils. This article has examined how paddy, yam, honey, etc. have been used in such literature

DESIGN AND IMPLEMENTATION OF MACHINE-CONTROLLED SYSTEM FOR PUBLIC BICYCLE-SHARING IN URBAN AREAS

This paper presents a design of machine controlled intelligent system for public to share bicycles for short distance transportation in urban areas. It allows us to take bicycle from wherever we are and to park at our nearest place of destination. The design schemes used here are automated system for bicycle delivery unit (base station) and bicycle parking unit (substation) and automatic amount collection for the usage from user card (RFID tags) and central administration office (GPS) and solar powered substations (PV solar panels). Moreover, it offers auto-locking racks for bicycles, on-Board vehicle tracking, and battery with solar power management, data logging, and communication with substations and administration. The subscribers can register to this service by administrator of bicycle sharing system. In 2011, the Ministry of Urban Development (MOUD), Government of India, launched the National Public Bicycle Scheme (NPBS) to build capacity for the implementation and operation of cycle sharing systems across the country. This paper outlines the advanced requirements to successfully develop and deploy bicycle sharing system focusing on solar powered battery charging and vending by PV solar panels, rental collection interface, in and out management of bicycles, system equipped with RFID and GPS tracking mechanisms. So bicycle sharing systems has emerged as an innovative form of public transport to provide urban short-distance transportation services by government

A case of placental chorioangioma

Chorioangioma is a benign tumor of placenta, incidence being 1 in 100 cases. It is mostly diagnosed ultrasonically in the second trimester of pregnancy. Large chorioangiomas render a challenge to obstetricians due to the foeto maternal complications and adverse outcomes. Here by authors present a case report of large chorioangioma with no fetomaternal complications but just for awareness of the importance of early diagnosis and to look out for possible adverse effects on mother and foetus

Microfluidics as a Powerful Tool to Investigate Microvascular Dysfunction in Trauma Conditions:A Review of the State‐of‐the‐Art

Skeletal muscle trauma such as fracture or crush injury can result in a life‐threatening condition called acute compartment syndrome (ACS), which involves elevated compartmental pressure within a closed osteo‐fascial compartment, leading to collapse of the microvasculature and resulting in necrosis of the tissue due to ischemia. Diagnosis of ACS is complex and controversial due to the lack of standardized objective methods, which results in high rates of misdiagnosis/late diagnosis, leading to permanent neuro‐muscular damage. ACS pathophysiology is poorly understood at a cellular level due to the lack of physiologically relevant models. In this context, microfluidics organ‐on‐chip systems (OOCs) provide an exciting opportunity to investigate the cellular mechanisms of microvascular dysfunction that leads to ACS. In this article, the state‐of‐the‐art OOCs designs and strategies used to investigate microvasculature dysfunction mechanisms is reviewed. The differential effects of hemodynamic shear stress on endothelial cell characteristics such as morphology, permeability, and inflammation, all of which are altered during microvascular dysfunction is highlighted. The article then critically reviews the importance of microfluidics to investigate closely related microvascular pathologies that cause ACS. The article concludes by discussing potential biomarkers of ACS with a special emphasis on glycocalyx and providing a future perspective

Drug-tolerant persister cancer cells are vulnerable to GPX4 inhibition.

Acquired drug resistance prevents cancer therapies from achieving stable and complete responses. Emerging evidence implicates a key role for non-mutational drug resistance mechanisms underlying the survival of residual cancer 'persister' cells. The persister cell pool constitutes a reservoir from which drug-resistant tumours may emerge. Targeting persister cells therefore presents a therapeutic opportunity to impede tumour relapse. We previously found that cancer cells in a high mesenchymal therapy-resistant cell state are dependent on the lipid hydroperoxidase GPX4 for survival. Here we show that a similar therapy-resistant cell state underlies the behaviour of persister cells derived from a wide range of cancers and drug treatments. Consequently, we demonstrate that persister cells acquire a dependency on GPX4. Loss of GPX4 function results in selective persister cell ferroptotic death in vitro and prevents tumour relapse in mice. These findings suggest that targeting of GPX4 may represent a therapeutic strategy to prevent acquired drug resistance

Ca2+ Efflux Facilitated by Co-transport of Inorganic Phosphate Anion in the H+/ca2+ Antiporter YfkE

Ca2+ is an important signaling messenger. In microorganisms, fungi, and plants, H+/Ca2+ antiporters (CAX) are known to play key roles in the homeostasis of intracellular Ca2+ by catalyzing its efflux across the cell membrane. Here, we reveal that the bacterial CAX homolog YfkE transports Ca2+ in two distinct modes: a low-flux H+/Ca2+ exchange mode and a high-flux mode in which Ca2+ and phosphate ions are co-transported (1:1) in exchange for H+. Coupling with phosphate greatly accelerates the Ca2+ efflux activity of YfkE. Our studies reveal that Ca2+ and phosphate bind to adjacent sites in a central translocation pathway and lead to mechanistic insights that explain how this CAX alters its conserved alpha-repeat motifs to adopt phosphate as a specific “transport chaperon” for Ca2+ translocation. This finding uncovers a co-transport mechanism within the CAX family that indicates this class of proteins contributes to the cellular homeostasis of both Ca2+ and phosphate

Synthesis of Certain Poly[bis(benzylidene)] Esters and Investigation on their Photocrosslinkability

Random copolyesters were synthesized directly from respective diacids and diols with diphenylchlorophosphate (DPCP) as a polycondensation agent. These polymers were characterized by FT-IR and NMR spectrometry. Interestingly, they were observed to possess photocrosslinkability which was established using scanning electron microscopy by UV irradiation experiments. Photocrosslinkable polymers have significant applications in the field of non-linear optics, in the generation of photoresists and photorefractive materials

Inflammatory effects of inhaled sulfur mustard in rat lung

Inhalation of sulfur mustard (SM), a bifunctional alkylating agent that causes severe lung damage, is a significant threat to both military and civilian populations. The mechanisms mediating its cytotoxic effects are unknown and were investigated in the present studies. Male rats Crl:CD(SD) were anesthetized, and then intratracheally intubated and exposed to 0.7–1.4 mg/kg SM by vapor inhalation. Animals were euthanized 6, 24, 48 h or 7 days post-exposure and bronchoalveolar lavage fluid (BAL) and lung tissue collected. Exposure of rats to SM resulted in rapid pulmonary toxicity, including focal ulceration and detachment of the trachea and bronchial epithelia from underlying mucosa, thickening of alveolar septal walls and increased numbers of inflammatory cells in the tissue. There was also evidence of autophagy and apoptosis in the tissue. This was correlated with increased BAL protein content, a marker of injury to the alveolar epithelial lining. SM exposure also resulted in increased expression of markers of inflammation including cyclooxygenase-2 (COX-2), tumor necrosis factor-α (TNFα), inducible nitric oxide synthase (iNOS), and matrix metalloproteinase- 9 (MMP-9), each of which has been implicated in pulmonary toxicity. Whereas COX-2, TNFα and iNOS were mainly localized in alveolar regions, MMP-9 was prominent in bronchial epithelium. In contrast, expression of the anti-oxidant hemeoxygenase, and the anti-inflammatory collectin, surfactant protein-D, decreased in the lung after SM exposure. These data demonstrate that SM-induced oxidative stress and injury are associated with the generation of cytotoxic inflammatory proteins which may contribute to the pathogenic response to this vesicant

Fatty acid desaturase-2 (ahFAD2) mutant alleles in peanut (Arachis hypogaea L.) pre-breeding lines: an insight into the source, features, discourse, and selection of novel pre-breeding lines

High oleic peanuts and derived food products offer longer shelf life benefits to the food processing industry in addition to multiple health benefits to the consumers. The two mutant alleles, ahFAD2A and ahFAD2B control composition of oleic, linoleic and palmitic acid content in peanut. A total of 563 peanut pre-breeding lines were tested for the presence ahFAD2A and ahFAD2B mutant alleles using allele specific markers. The ahFAD2A mutant allele was present in 82 lines, while none of these lines had ahFAD2B mutant allele. Among botanical types, ahFAD2A mutant allele was more frequent in lines with Virginia growth habit than Spanish bunch although no correlation of ahFAD2A mutant allele with high oleic acid content and growth habit could be established. Oleic and linoleic acid content in 82 prebreeding lines ranged from 39.70 to 62.70% and 17.76 to 31.95%, respectively, with maximum oleic to linoleic acid ratio of 4. Oleic acid was found to be negatively correlated with linoleic and palmitic acid. Further, pre-breeding lines with ahFAD2A mutant allele, high oleic content and high oleic to linoleic ratio were investigated and novel lines were identified for resistance to late leaf spot, short duration, higher pod yield and other yield related traits. These novel pre-breeding lines can be used as a potential donor in peanut improvement programme and to diversify the primary gene pool including initiating further research on induction of fresh ahFAD2B mutant allele
