Development of non-formaldehyde wrinkle resistant finish for cotton using carboxylic acids
475-481A study has been conducted to develop a wrinke resistant cotton fabric using three carboxylic acids combination along with initiator and catalyst, at various pH and concentration, and to determine the effects of treatment on wrinkle recovery angle, wrinkle recovery appearance rating, and carboxyl group content of the treated fabrics. The amount of carboxylic acids on the fabric is determined by % weight gain of treated samples, carboxyl ‘n’ group content, wrinkle recovery angle and wrinkle recovery appearance rating. Furthermore, FTIR spectroscopic analysis has been conducted to study the attachment of acid groups for reducing the available free OH groups on the cotton cellulosic chains. The results show significant wrinkle resistance of treated samples. In order to evaluate the wash durability of the finish applied, the treated sample is laundered for 20 cycles and it is found that the wrinkle recovery property significantly persist even after washing
Port side tubercular abscess in women after lap-diagnosis for infertility
Infertility whether primary or secondary is an emotional and financial burden to the concerned family. In India we occasionally deal with financial constraints of the women undergoing treatment for infertility. Women getting post procedure port site tubercular abscess further makes the situation worse leading to long term burden of drug intake which could have been avoided by proper knowledge and use of sterilization technique of laparoscopic instruments.

Truncated hemoglobin, HbN, is post-translationally modified in Mycobacterium tuberculosis and modulates host-pathogen interactions during intracellular infection
Mycobacterium tuberculosis (Mtb) is a phenomenally successful human pathogen having evolved mechanisms that allow it to survive within the hazardous environment of macrophages and establish long term, persistent infection in the host against the control of cell-mediated immunity. One such mechanism is mediated by the truncated hemoglobin, HbN, of Mtb that displays a potent O2-dependent nitric oxide dioxygenase activity and protects its host from the toxicity of macrophage-generated nitric oxide (NO). Here we demonstrate for the first time that HbN is post-translationally modified by glycosylation in Mtb and remains localized on the cell membrane and the cell wall. The glycan linkage in the HbN was identified as mannose. The elevated expression of HbN in Mtb and M. smegmatis facilitated their entry within the macrophages as compared with isogenic control cells, and mutation in the glycan linkage of HbN disrupted this effect. Additionally, HbN-expressing cells exhibited higher survival within the THP-1 and mouse peritoneal macrophages, simultaneously increasing the intracellular level of proinflammatory cytokines IL-6 and TNF-α and suppressing the expression of co-stimulatory surface markers CD80 and CD86. These results, thus, suggest the involvement of HbN in modulating the host-pathogen interactions and immune system of the host apart from protecting the bacilli from nitrosative stress inside the activated macrophages, consequently driving cells toward increased infectivity and intracellular survival
Mapping local patterns of childhood overweight and wasting in low- and middle-income countries between 2000 and 2017
A double burden of malnutrition occurs when individuals, household members or communities experience both undernutrition and overweight. Here, we show geospatial estimates of overweight and wasting prevalence among children under 5 years of age in 105 low- and middle-income countries (LMICs) from 2000 to 2017 and aggregate these to policy-relevant administrative units. Wasting decreased overall across LMICs between 2000 and 2017, from 8.4% (62.3 (55.1–70.8) million) to 6.4% (58.3 (47.6–70.7) million), but is predicted to remain above the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025. Prevalence of overweight increased from 5.2% (30 (22.8–38.5) million) in 2000 to 6.0% (55.5 (44.8–67.9) million) children aged under 5 years in 2017. Areas most affected by double burden of malnutrition were located in Indonesia, Thailand, southeastern China, Botswana, Cameroon and central Nigeria. Our estimates provide a new perspective to researchers, policy makers and public health agencies in their efforts to address this global childhood syndemic
Computational Identification Raises a Riddle for Distribution of Putative NACHT NTPases in the Genome of Early Green Plants.
NACHT NTPases and AP-ATPases belongs to STAND (signal transduction ATPases with numerous domain) P-loop NTPase class, which are known to be involved in defense signaling pathways and apoptosis regulation. The AP-ATPases (also known as NB-ARC) and NACHT NTPases are widely spread throughout all kingdoms of life except in plants, where only AP-ATPases have been extensively studied in the scenario of plant defense response against pathogen invasion and in hypersensitive response (HR). In the present study, we have employed a genome-wide survey (using stringent computational analysis) of 67 diverse organisms viz., archaebacteria, cyanobacteria, fungi, animalia and plantae to revisit the evolutionary history of these two STAND P-loop NTPases. This analysis divulged the presence of NACHT NTPases in the early green plants (green algae and the lycophyte) which had not been previously reported. These NACHT NTPases were known to be involved in diverse functional activities such as transcription regulation in addition to the defense signaling cascades depending on the domain association. In Chalmydomonas reinhardtii, a green algae, WD40 repeats found to be at the carboxyl-terminus of NACHT NTPases suggest probable role in apoptosis regulation. Moreover, the genome of Selaginella moellendorffii, an extant lycophyte, intriguingly shows the considerable number of both AP-ATPases and NACHT NTPases in contrast to a large repertoire of AP-ATPases in plants and emerge as an important node in the evolutionary tree of life. The large complement of AP-ATPases overtakes the function of NACHT NTPases and plausible reason behind the absence of the later in the plant lineages. The presence of NACHT NTPases in the early green plants and phyletic patterns results from this study raises a quandary for the distribution of this STAND P-loop NTPase with the apparent horizontal gene transfer from cyanobacteria
Non-formaldehyde wrinkle resistant finish for linen
Linen, even though it has a beautiful drape, is highly susceptible to wrinkles, especially under high humidity. A study was conducted to develop a wrinkle-resistant finish using a combination of three carboxylic acids at various pΗ and concentrations on linen fabric. The treated fabric was analyzed to determine the effect on wrinkle recovery angle, wrinkle recovery appearance rating, and carboxyl group content. The amount of finish application on the fabric was governed by percent weight gain of treated samples, carboxyl ‘n’ group content, wrinkle recovery angle, and wrinkle recovery appearance rating. Furthermore, a reduction in the availability of free OH groups in the linen cellulosic chains was studied using FTIR spectroscopic analysis to qualitatively analyze the attachment of acid groups to the monomers of the fiber polymeric chain. The results showed significant wrinkle resistance for treated samples
Thenoyltrifluoroacetone as a spectrophotometric reagent for determination of ascorbic acid
2541-2544An extractive spectrophotometric method for
the determination of microamounts of ascorbic acid is described.1-[Thenoyl-
(2')-3,3,3-trifluoro-acetone] (HTTA) is found to react with iron (III) in strongly
acidic medium giving a red coloured complex. The method is based on the proportionate
decrease in the colour intensity of Fe(III)-HTTA complex with the addition of ascorbic
acid at 405 nm. Linear calibration curve is observed in the range 1.0-5.0 μg/mL of
ascorbic acid. The molar absorptivity and Sandell's sensitivity are 5.3×104
L/mol/cm and 0.003μg/cm2, respectively. The interference
of sugars, vitamins, amino acids, mineral salts, sweetening agents etc. has been
studied. The method is success fully used in the determination of ascorbic acid
in pure vitamin C tablets, drops and multivitamin products
Extractive spectrophotometric determination of iron using 3-hydroxy-2-(2-thienyl) -4H chromen-4-one
552-553A highly sensitive method
is described for the determination of iron (III). Iron(III) forms a brown coloured complex with 3-hydroxy-2-(2-thienyl)-4H-chromen-4-one (HTC) in acidic medium which
is conveniently
extracted into
chloroform. The absorbance of
the complex
