Condom catheter: a simple and efficacious alternative of hysterectomy in postpartum haemorrhage

Background: The aim of this study was to evaluate the effectiveness of the condom catheter in treating postpartum hemorrhage refractory to medical treatment.Methods: This prospective study included 21 women with postpartum hemorrhage treated with a condom catheter as a conservative therapeutic option.Results: The condom catheter was successful in controlling hemorrhage in 90.4% of the women. It was effective in all women with vaginal delivery (11 of 12) and highly effective in women with uterine atony who did not respond to medical uterotonic treatment (6 of 7 women).Conclusions: Its ease of use and high effectiveness make the condom catheter a useful approach for the conservative management of acute postpartum hemorrhage. This device reduces bleeding, shortens the hospital stay and avoids the need for surgical management

Mercury Cadmium Telluride Photoconductive Long Wave Infrared Linear Array Detectors

Mercury cadmium telluride (Hg1-x, CdxTe) (MCT) photoconductive long wave infrared linear arrays are still in demand due to several advantages. The linear array technology is well established, easier, economical and is quite relevant to thermal imaging even today. The scan thermal imaging systems based on this technology offer wider field of view coverage and capacity for higher resolution in the scan direction relative to staring systems that use expensive and yet to mature focal plane array detector technology. A critical review on photoconductive n-Hg1-x CdxTe linear array detector technology for the long wave infrared range has been presented. The emphasis lies on detector design and processing technology. The critical issues of diffusion and drift effects, Hi-Lo and heterostructure blocking contacts, surface passivation, and other related aspects have been considered from the detector design angle. The device processing technology aspects are of vital importanc

Comparison of maternal and perinatal outcome in pregnancy with altered thyroid profile and euthyroid patients: a prospective, observational and case control study in a tertiary care centre

Background: Thyroid disease is one of the commonest endocrine disorder affecting women of reproductive age, and when untreated during pregnancy is associated with an increased risk of complications. The objective of this review was to increase awareness and to provide a review on adverse effect of thyroid dysfunction on maternal and perinatal outcome.Methods: This prospective, observational hospital-based case-control study carried on women coming for antenatal check-up in a Tertiary Care Hospital in INDORE from May 2018-December 2018. 50 known booked antenatal (case) patient with established thyroid disorder, more than 32 week of gestation, and 50-matched euthyroid patients (control) were taken.Results: Women suffering from overt and subclinical hypothyroidism and hyperthyroidism are nulliparous in 72% cases as compared to 32% in euthyroid patient. Increased maternal age was associated with higher incidence of thyroid dysfunction. Normal vaginal delivery by spontaneous labour seen in 56% of euthyroid, while it is reduced with thyroid dysfunction. 38% of altered thyroid profile patient undergo induction of labour and 24% cases undergo caesarean section as compared to control (17%). Adverse fetal outcome like intrauterine growth retardation, preterm birth and ICU admission seen increased with thyroid dysfunction  as compared to euthyroid patients.Conclusions: Thyroid dysfunction in pregnancy, although has a low incidence, but is associated with adverse maternal and fetal implications. Thus, thyroid screening should be done in antenatal period to improve fetomaternal outcome

Microwave assisted template synthesis of metal based EGFR, TRK inhibitors, molecular docking and in vitro biological studies

752-759Metal based biologically active compounds have been synthesized by microwave assisted template condensation method and characterized by spectro-analytical techniques like molar conductance, UV-visible, infrared and mass spectroscopy and thermogravimetric analysis. The metal is arranged in octahedral geometry surrounded by tetradentate ligand framework. The binding affinity of all the metal complexes has been evaluated theoretically by molecular docking studies against epidermal growth factor receptor (EGFR) and tyrosine kinase (TRK) receptor molecules which are further verified by in vitro anticancer activity.

Evaluation of different paddy straw management technologies for their economic viability in rice-wheat system

The study examines the economics of different paddy straw management methods in rice-wheat systems in Gurdaspur, Punjab during the Rabi seasons (2019-20 and 2020-21). The experiment was carried out with 2 wheat varieties, HD 3086 (V1) and PBW 550 (V2), using varied treatment combinations of crop residue management approaches, tillage and seed drilling methods. Based on the pooled data, the PAU (Punjab Agricultural University) cutter cum spreader + incorporation with Mould Board plough + Use of Seed drill (M4) treatment produced the highest plant height (95.87 cm). Treatment PAU cutter cum spreader + PAU happy seeder with press wheel (M2) (437.71) had the highest density of tillers per square meter, significantly outperforming other treatments. A significant interaction was observed between paddy residue management methods and varieties in terms of the number of tillers. Maximum spike length (12.81 cm) was obtained with Stubble Shaver + Burning + Zero Tillage Drill (M1), whereas maximum number of spikelets per spike (18.33) was noted in method (M2). The treatment method (M2) turned out to be the most efficient in terms of yield (44.02 q/ha) and benefit cost ratio (1.72)

M. tuberculosis Sliding β-Clamp Does Not Interact Directly with the NAD+ -Dependent DNA Ligase

The sliding β-clamp, an important component of the DNA replication and repair machinery, is drawing increasing attention as a therapeutic target. We report the crystal structure of the M. tuberculosis β-clamp (Mtbβ-clamp) to 3.0 Å resolution. The protein crystallized in the space group C2221 with cell-dimensions a = 72.7, b = 234.9 & c = 125.1 Å respectively. Mtbβ-clamp is a dimer, and exhibits head-to-tail association similar to other bacterial clamps. Each monomer folds into three domains with similar structures respectively and associates with its dimeric partner through 6 salt-bridges and about 21 polar interactions. Affinity experiments involving a blunt DNA duplex, primed-DNA and nicked DNA respectively show that Mtbβ-clamp binds specifically to primed DNA about 1.8 times stronger compared to the other two substrates and with an apparent Kd of 300 nM. In bacteria like E. coli, the β-clamp is known to interact with subunits of the clamp loader, NAD+ -dependent DNA ligase (LigA) and other partners. We tested the interactions of the Mtbβ-clamp with MtbLigA and the γ-clamp loader subunit through radioactive gel shift assays, size exclusion chromatography, yeast-two hybrid experiments and also functionally. Intriguingly while Mtbβ-clamp interacts in vitro with the γ-clamp loader, it does not interact with MtbLigA unlike in bacteria like E. coli where it does. Modeling studies involving earlier peptide complexes reveal that the peptide-binding site is largely conserved despite lower sequence identity between bacterial clamps. Overall the results suggest that other as-yet-unidentified factors may mediate interactions between the clamp, LigA and DNA in mycobacteria
