Safety and Quality of Nutraceuticals: Have FSSAI Guidelines been Able to Blaze the Trail?

The nutraceutical industry has three main segments, including herbal/- natural products, dietary supplements and functional foods. The dietary supplements market is preliminarily driven by the paradigm shift towards preventive health management practices, amid rising healthcare costs and increasing burden of lifestyle diseases. Rise in healthcare expenditure, increased usage of nutraceuticals product as a substitute to prescription and OTC drugs and augmented demand for the nutritional diet are the major factors driving the global nutraceuticals market. Many individual laws were devised to govern its manufacturing and sale. However, increasing regulatory formalities from multiple agencies and laws, complicate the development, testing and marketing of these substances and hamper the growth of the nutraceutical market. Globally, the regulatory authorities are aware of the changing needs of consumers and proactively protect consumers by amending existing laws to accommodate changes. Market entry requirements of nutraceuticals, functional foods and supplements vary from country to country. The global regulatory guidelines aim at regulating various aspects of the nutraceutical and dietary supplements market, focusing on its manufacture, testing, labeling, sale and registration to assure safety and quality of the product. The major change that was introduced was the ban on marketing Nutraceuticals as medicinal products. This review has been performed to provide a comprehensive understanding of the global regulatory requirements with critical analysis of the Indian regulatory guidelines to explore the lacunae and suggest the need of further amendments in the form of recommendations that can be incorporated into regulatory body guidelines to make it more competitive for national & international trade.

Global artificial intelligence systems and technology market: formation and development trends

Every day more and more companies rely on artificial intelligence, from small startups to large companies, among which stand out not only the IT giants Google, Microsoft, Facebook, IBM, but even those that seemingly far from this topic - for example, General Motors and Boeing created a joint laboratory for AI research. It becomes obvious that AI technology is the real mainstream of our time. The article examines the global market for artificial intelligence systems and technologies. The authors described the peculiarities of the formation of this market and the main trends and segments in its development.

MacEmerg Podcast: A Novel Initiative to Connect a Distributed Community of Practice.

Regional knowledge dissemination and information sharing is a challenge among physically divided groups of physicians. Many staff and resident physicians do not have easy access to share clinical and medical education and research information with each other in an academic setting. Our divisions of emergency medicine could benefit from a novel approach aimed at improving overall connection and collaborative engagement. By harnessing the sociomateriality properties of podcasting, we could achieve the dual goals of better connecting our faculty as well as educating the audience on aspects of clinical practice and education that are especially relevant to our region. We sought to primarily draw on local expertise for content. We developed a standardized structure for our monthly releases, with each episode composed of a main faculty segment, a resident-focused segment, and a medical education segment. Accessibility to the podcast was maximized through its publication across multiple platforms and detailed individual show notes were made available. We applied logic model methodology with the intended goal of having much of our content consumed by local faculty and trainees. Using Web-based analytic data, we were able to ascertain the proportion and number of listens that occurred from within our local university-affiliated and/or catchment region. Episodes averaged 227.7 ± 67.2 listens with an overall 44.1% of those originating from within our defined region. Given the number of regional listeners we are consistently reaching, we have been effective in serving to connect a widely distributed group of academic physicians. As we continue to grow the podcast, we plan on collecting quantitative data to better ascertain its effect on our stated goals.

Present‐Day Deformation Mechanism of the Northeastern Mina Deflection Revealed by the 2020 Mw 6.5 Monte Cristo Range Earthquake

AbstractThe 15 May 2020 Monte Cristo Range Mw 6.5 earthquake occurred in the northeast of the Mina deflection, which accommodates approximately a quarter of the relatively dextral motion between the Pacific and North American plates. The Monte Cristo Range event provides an opportunity to study the present‐day regional deformation mechanism and active tectonics. In this study, we investigate the source rupture process of the event using joint inversion of interferometric synthetic aperture radar and broadband seismic data. We find that the rupture propagates almost simultaneously on two main segments. The fault motion changes from the predominantly sinistral slip near the epicenter on the eastern segment to the oblique slip on the western segment, with a maximum coseismic slip of 0.8 m. Our results suggest that the accommodation of slip transfer localized in the northeastern Mina deflection tends to transform from the wrench‐ to extension‐dominated transtension.

Age-proofing a traffic saturated metropolis – Evaluating the influences on walking behaviour in older adults in Ho Chi Minh City

Walking is an essential mode of travel for older adults, offering significant health benefits. However walking as a travel mode in Vietnam is constrained by poor built environment quality and safety, which act as a psychological barrier to pedestrians in a traffic saturated environment. This study explores an extension of the Theory of Planned Behaviour (TPB) by incorporating built environment quality and safety constructs, along with proximity to destination types and vehicle availability indicators. A survey of active older adults (n = 832, aged 55 to 72) was designed and administered within four inner districts in Ho Chi Minh City (HCMC) to elicit socio-demographic, travel characteristics and psychometric data about past walking behaviour and future intention. A partial-least squares structural equation model (PLS-SEM) was used to conduct path and multi-group analyses (MGA) on main activity segments (retired, working at home and working outside), revealing statistically significant paths with satisfactory variance explained in a conceptual extended Theory of Planned Behaviour (eTPB) framework. The results show that intention to walk can be explained by past behaviour, with mediating effects from other factors, such as built environment and safety, via the standard TPB constructs (attitudes, subjective norms and perceived behavioural control). A clear relationship emerges between the factors examined, but with some exceptions and difference in MGA. This study demonstrates the importance of understanding older adults through examination of their main activity status. We also call for the development of travel behaviour and urban intervention programs to improve walking uptake and safety for older adults.

Keeping α-Synuclein at Bay: A More Active Role of Molecular Chaperones in Preventing Mitochondrial Interactions and Transition to Pathological States?

The property of molecular chaperones to dissolve protein aggregates of Parkinson-related α-synuclein has been known for some time. Recent findings point to an even more active role of molecular chaperones preventing the transformation of α-synuclein into pathological states subsequently leading to the formation of Lewy bodies, intracellular inclusions containing protein aggregates as well as broken organelles found in the brains of Parkinson’s patients. In parallel, a short motif around Tyr39 was identified as being crucial for the aggregation of α-synuclein. Interestingly, this region is also one of the main segments in contact with a diverse pool of molecular chaperones. Further, it could be shown that the inhibition of the chaperone:α-synuclein interaction leads to a binding of α-synuclein to mitochondria, which could also be shown to lead to mitochondrial membrane disruption as well as the possible proteolytic processing of α-synuclein by mitochondrial proteases. Here, we will review the current knowledge on the role of molecular chaperones in the regulation of physiological functions as well as the direct consequences of impairing these interactions—i.e., leading to enhanced mitochondrial interaction and consequential mitochondrial breakage, which might mark the initial stages of the structural transition of α-synuclein towards its pathological states.

Atomistic finite element modeling of superlubricity in long double walled carbon nanotubes

The question of how much the nanotubes are really superlubricious when they are at macro lengths, is still intriguing. In this research, multiscale modeling of wall separation for various double walled carbon nanotube pairs has been done. VDW forces are modeled by a 3D truss element based on Lennard-Jones potentials, while C–C bonds are modeled by a deformable and equivalent beam elements. In the steady pullout process, we divided DWCNT into 3 main effective segments and characterized their effects separately; (a) free and pulled out length, (b) end atom VDWs, and (c) overlapping region. The effects of each aforementioned segments are separated by doing a proper finite element coding. For the zigzag/zigzag pairs, the end atoms are responsible for the average load while the overlapping region answers the load fluctuation during pullout. Otherwise, for the incommensurate case of zigzag/armchair pair, both end atoms and overlapping loads are constant. Finally for the armchair/armchair DWCNT, the end atom and the overlapping loads both are fluctuating, however at different phases that makes its overall pullout force constant. The methodology and coding introduced in this numerical effort makes it possible to precisely determine the average pullout load for long nanotubes with lengths in the order of hundreds of nanometers in short computational time.

Renal morphological description of brown brocket deer, Mazama gouazoubira, Fisher 1814 (Artiodactyla; cervidae)

The brown brocket deer (Mazama gouazoubira) is a deer that lives in South America, particularly in Brazil and nearby countries such as Uruguay and Argentina. This study aimed to describe the topography, morphology, wraps and renal arterial segments of brocket deer. Used two specimens of M. gouazoubira; through dissection, the skin was completely removed and later scored the arteries of animals with stained latex red later the animals were fixed in a formaldehyde solution 10%. Sequentially through a ventral access block was removed from the animal gut and kidneys disjoint this block. The right kidney located at the level of the vertebrae L1-L3 and the left kidney at the level of vertebrae L2-L4 were presented rounded with smooth convex faces without lobation, wrapped sequentially by a thin fibrous capsule, the renal fat and fascia capsule. Medial to each kidney, the adrenal glands were. Renal artery forked in the hilar region in the cranial and caudal artery sectoral and one of these sectoral arteries (cranial and caudal) originated five main segments directed to the ventral region and the dorsal region each kidney, these segments are again bifurcated arterial segments totaling 14. Microscopically the kidneys presented similar organization to that presented by the ruminants with cortical and medullary region with fused lobes. The kidneys brocket deer resemble the kidneys of other ruminants in general, and to carnivores. Thus, its morphology, topography and the renal arterial segments and anatomical and surgical territories of the species studied have been shown to be unique.

The deformation and mechanisms of the Zhangbaling tectonic belt during Indosinian to early Yanshanian: Implications for the relationship with the Tan-Lu Fault Zone

The Zhangbaling tectonic belt is located in the middle segment of Dabie-Sulu Orogenic Belt and in the eastern part of the main segment of the Tan-Lu Fault Zone (TLFZ). Based on detailed field work and comprehensive analysis, this study discussed the tectonic evolution mechanics of the Zhangbaling tectonic belt and the Tan-Lu Fault Zone as well as the relationship between them during Indosinian to early Yanshanian period. Three stages of tectonic deformation have been determined in the period from Indosinian to early Yanshanian in Zhangbaling area, i.e., a series of WNW and nearly EW trending tight congruous nearly recumbent folds formed in the early stage; a flatly ductile shearing zone formed mainly between Beijiangjun lithofm. and Xileng lithofm. in the middle stage and the demonstrate NNE trending wide flat folds and strong thrusting or napping from NW to SE formed in the last stage. The superimposition of these three deformation stages formed the basic tectonic framework of this area. The folding and thrusting (sliding in the front margin) was developed in the mid-upper crust (include sedimentary cover) during the period of subduction and collision processes between South China Block and North China Block, shows a progress deformation of the three stages during the period of Indosinian and early Yanshannian due to the conversion of the Tethyan to the Circle Pacific Ocean tectonic regimes. The Tan-Lu Fault Zone can be divided into two big development phases since Hercynian. The first phase is a fault zone sensu lato, as a boundary of a rifted cratonic margin (or basin) that shows a wide arc-shaped along the northeastern margin of the South China Block during Indosinian. The TLFZ of this period is a collision suture between South China Block and North China Block during Indosinian period, a thrust-napping fault zone belong to the Tethyan regimes sensu lato, as well as the southeast margin of the Zhangbaling tectonic belt. This big phase corresponds to the three stages deformation activities in Zhangbaling area. The second phase is a wrench fault system usually mentioned by most researchers, which belongs to the Pacific Ocean Cycle Regime sensu stricto since early Yanshanian to Himalayan periods.

Efeitos da COVID-19 sobre a economia do semiárido baiano: dinâmica atual e implicações futuras

Este trabalho avalia cenários para a região semiárida baiana, no processo de recomposição da economia brasileira, após a crise de saúde do novo coronavírus (Covid-19). O estudo parte do entendimento de que é inevitável a adoção de políticas de expansão do gasto público para achatar a curva de recessão sem agravar a curva de infecção. Tomando essa compreensão por referência, a hipótese básica é de que a necessidade de reequilibrar as contas públicas no longo prazo, implicadas pelas medidas de isolamento social, levará os governos a reduzirem a participação do estado na economia, comprometendo as regiões mais pobres. Como a administração pública é o principal segmento da atividade econômica e os programas de transferência de renda estão na base da dinâmica econômica dos municípios do semiárido baiano, as políticas de ajuste futuro irão comprometer o desenvolvimento da região, agravando os desequilíbrios regionais e as desigualdades sociais. Conclui-se com cenários desfavoráveis para o semiárido baiano, em decorrência da perda de dinamismo econômico.

Desempenho reológico e de filtração de fluidos de perfuração base óleo preparados com argilas bentoníticas provenientes do município de Boa Vista-PB

<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p>As argilas bentoníticas constituem um insumo imprescindível à elaboração de fluidos de perfuração. Pode-se destacar que um dos principais segmentos consumidores de argila bentonítica é a indústria petrolífera, na qual ela é usada como agente tixotrópico em fluidos de perfuração de poços de petróleo, atribuindo aos fluidos características físicas e propriedades químicas e reológicas específicas. Segundo Leal (2012), as propriedades físico-químicas e reológicas devem ser cuidadosamente controladas para que o fluido possa exercer todas as suas funções, tais como resfriar a broca, formar uma camada de baixa permeabilidade e manter os sólidos em suspensão, a fim de garantir o seu bom desempenho na perfuração de poços. Foram estudadas três amostras de argilas bentoníticas sódicas industrializadas provenientes de jazidas da região de Boa Vista-PB. Para organofilização das argilas, foi utilizado sal quaternário de amônio; a reologia foi determinada, e observou-se que é possível obter formulações de fluidos de base óleo aditivadas com argila.</p></div></div></div>

A cochlea with three parts? Evidence from otoacoustic emission phase in humans.

The apical and basal regions of the cochlea appear functionally distinct. In humans, compelling evidence for an apical-basal transition derives from the phase of otoacoustic emissions (OAEs), whose frequency dependence differs at low and high frequencies. Although OAEs arising from the two major source mechanisms (distortion and reflection) both support the existence of an apical-basal transition-as identified via a prominent bend (or "break") in OAE phase slope-the two OAE types disagree about its precise location along the cochlea. Whereas distortion OAEs at frequency 2f1-f2 suggest that the apical-basal transition occurs near the 2.5 kHz place, reflection OAEs locate the transition closer to 1 kHz. To address this discrepancy, distortion and reflection OAEs were measured and analyzed in 20 young human adults from 0.25-8 kHz and at eight primary-frequency ratios f2/f1 in the range 1-1.5. Break frequencies and OAE phase-gradient delays were estimated by fitting segmented linear models to the unwrapped phase. When distortion- and reflection-OAE phase are considered as functions of ln f2-that is, as linear functions of the location of their putative site of generation within the cochlea-the analysis identifies not just two but three main cochlear segments, meeting at transition frequencies of approximately 0.9 and 2.6 kHz, whose locations are largely independent both of primary-frequency ratio and emission type. A simple model incorporating an abrupt transition from wave- to place-fixed behavior near the middle of the cochlea accounts for key features of distortion-OAE phase.

Carbonate reservoir evaluation and gas bearing prediction in Ordos Basin

In order to solve the problem that carbonate rocks are difficult to be explored due to their complex heterogeneity, the evaluation of carbonate reservoirs and the prediction of gas bearing are carried out. Firstly, taking the Sugeri gas field area in Ordos as an example, the address characteristics of the research area are introduced. Then the petrological characteristics and reservoir spatial characteristics (pore types and pore structures) of carbonate reservoirs are explored. In addition, the prediction and simulation method of carbonate reservoir gas bearing—amplitude variation with offset (AVO) forward modeling analysis method is discussed. Finally, the results of reservoir characteristics and prediction of reservoir gas bearing are analyzed. The results show that there is no effective reservoir development in Ma Wu32, Ma Wu33, and Ma Wu41b in the study area, and Ma Wu41a is the main effective reservoir development segment, followed by Ma Wu2 subsegment. For gas bearing prediction, there are a total of 10 favorable zones in Ma Wu segment, among which the predicted gas thickness is between 2 and 8 m. The results have good guiding significance for oil and gas exploration in China.
