Water as carrier of information of heat shock and drug effect between two groups of Adhatoda vasica plants

Adhatoda vasica Nees plants were grown in 50 earthen pots, which were divided into 5 batches A, B, C, D, and E. Of these A, B and C, D were arranged into two separate parallel pairs. One leaf of each plant of an adjacent pair was immersed in sterile tap water in a beaker. Adjacent beakers in each pair A B or C D were connected by polythene tubes containing wet cotton threads. One leaf of each plant of A was given heat shock by immersing a leaf in hot water for 5 min. One leaf of each plant of C was treated with Cantharis vesicatoria 200c. Batch E served as the unstressed and untreated control. One hour after heat shock or drug treatment all the leaves were harvested and their proteins were extracted by chilled protein extraction buffer. Proteins were separated by Fast Protein Liquid Chromatography (FPLC). Protein profiles of A, B and C, D showed marked similarity with respect to expression and repression of some proteins. It is concluded that the effect of heat shock and drug treatment is transmitted through water in the capillaries of cotton threads connecting the pairs of plants. It is assumed that heat shock or drug treatment altered locally the water structure in the leaves which was propagated through global network of water structure over the protein network in the whole plants, and from there to the interfacial water in the beakers and cotton threads. A homeopathic potency is thought to be specifically structured water which influences the water structure in the treated organism.

Perkembangan Pembuatan Tenun Melayu Siak : Suatu Tinjauan Historis

The siak weaving is a cultural heritage of Riau Malay. The motifs on the Siak Tenun have certain philosophical meanings. In addition, in the manufacturing process, there has been a development both from the materials and tools used. The study in this paper aims to describe the development of Siak weaving techniques based on the categories of materials and tools used from time to time. The method used in this study is the historical method with heuristic, verification, interpretation, and historiography stages. The result of the study is that the making of Siak Weaving has developed in terms of the materials and tools used. In terms of materials, at the beginning of its development using materials from silk, gold, and silver threads. However, since 1950 the weavers began to use cotton threads along with the high prices of silk, gold, and silver threads. Furthermore, in terms of tools, in 1764 the first weaving tool used was the tumpu loom. The tools used for the manufacture of Siaik weaving are increasingly developing, since 1990 it has been replaced by non-machine weaving tools (ATBM). The development of the Siak Tenun making tool to increase production output and shorten processing time. From the results of the study, it can be concluded that changes in the weaving production equipment affect the impact, including the number of workers, budget efficiency, quality, and quantity of production.

Racialized authenticity: South Asian migrant women in the ethnic beauty market

Over the last two decades, ethnic beauty markets in Los Angeles have grown rapidly as cultural commodification soars alongside the growth of migrant workers in the global city. The South Asian beauty industry, in particular, has emerged as a site where there is a hypervisibility of ethnic aesthetic practices, such as threading hair removal and henna art, as well as South Asian migrant women who are formally and informally employed in these salons. Threading, often marketed as an Indian, Asian, Ayurvedic and/or Eastern hair removal technique, uses intertwined cotton threads that are rolled across the skin to pluck hair out from the roots. This growing market for threading services has uniquely relied on the labor of migrant women from the subcontinent, one that has been sustained through efforts to authenticate women’s labor as desirably Other. Based on 22 months of ethnographic fieldwork in the South Asian beauty industry, this article examines the structural mechanisms through which migrant women are racialized as ‘authentic’ workers with a focus on businesses’ hiring practices resulting in the hypervisibility of migrant women in the industry, marketing and advertising of these services, as well as state legislation. I use the term ‘racialized authenticity’ to understand these structural productions and the ways they inform the context within which beauty industry interactions take place. These interactions occur in threading salons where racialized expectations around un/desirability are encountered by workers and consumers as well as in training programs where threading is taught. Together, these insights reveal the contradictory forms of South Asian racialization in the US that allow workers to authenticate their labor as desirable for consumers while simultaneously signaling their foreignness.

THERMOGRAPHY OF PERIODONTAL TISSUES DURING DIATHERMOCOAGULATION RETRACTION

Gingival retraction at the preparatory stage of orthopedic teeth restoration with fixed dental appliances is a common procedure in daily dental practice, the success of which will depend on the effectiveness of orthopedic treatment in general. Given certain shortcomings of well-known mechanical and mechano-chemical retraction techniques, the consequences of which may lead to unpredictable aesthetic results, the purpose of this work was to study changes in temperature of marginal gums around teeth at different stages of their orthopedic restoration by fixed metal-ceramic structures based on the thermography findings. The study included 54 patients aged 20 to 60 years, with partial or complete destruction of the coronal part, among whom there were 29 people (53.7%) who underwent gum retraction by diathermocoagulation, and 25 people (46.3%) who underwent retraction of the gingival groove with cotton threads "Ultrapak" (“Ultradent", USA). Measurements were performed prior the operation, during it, in 60 minutes after the completion of diathermocoagulation, and in 7 days after fixation of the cermet crown (14 days after retraction). The thermographic study showed that immediately after the procedure of diathermocoagulation retraction, the temperature of the marginal mucosa went up from 27.3° C (St.Err. 0.28) to 60.2° C (St.Err. 0.72) in the group 1, while in group 2 after mechanochemical retraction there was an increase in temperature from 27.3° C (St.Err. 0.30) to 28.9° C (St.Err. 0.3). 60 minutes after the end of the retraction, the average thermographic index in the group 1 was 28° C (St.Err. 0.28), while in group 2 it equalled to 28.1° C (St.Err.0.31). Control thermography on the 14th day after gum retraction showed a slight decrease to 27.1° C (St.Err. 0.29) in the group 1, and 26.72° C (St.Err. 0.29) in the group 2. The use of diathermocoagulation method of preparation (retraction) of abutment teeth in case of partial or complete destruction of their coronal part improves the quality of orthopedic treatment of patients by using metal-ceramic constructions of dentures. Analysis of thermodynamics in dental and periodontal tissues using the latest thermographic devices with subsequent computer processing of information obtained is of great prospects for further in-depth research.

INCREASING OF THERMAL FIRE RESISTANCE OF COTTON THREADS

The results of studies of fire - resistant impregnating compositions based on an aqueous solution of polyvinyl alcohol and an antipyretic additive-methylphosphite borate are presented. The effectiveness of single-stage processing of cotton threads with these impregnating compositions has been proved. It is established that the developed impregnating compositions for cotton threads have shown high efficiency of thermal and fire-retardant action. The influence of the developed impregnation formulations on water absorption and strength of cotton threads was evaluated.

Instrument-free detection of polyphenols with a thread-based analytical device

We described an instrument-free method for quantitative analysis of the total content of tea polyphenols by measurement of the length of a coloured band. Polyphenols react with ferrous ions to form a colourless ferrous-polyphenols complex on cotton threads, which could be adsorbed on the threads. The complex was then oxidized to form a blue-black ferric-polyphenols complex, generating a blue-black band on the cotton thread. The length of this blue-black band was then measured to detect the total content of polyphenols. The advantages of this method include low cost, rapid analysis, low consumption, easy fabrication and operation. Furthermore, the digital instrument (scanner or camera) as well as the image processing software are not required. This proposed method was used to detect polyphenols in tea leaf extracts with an analytical result agreeing well with that obtained by a standard method, which demonstrates its potential in monitoring of tea leaf quality, especially in resource-limited regions and settings.
