AbstractDifferentiation of granular bainite and polygonal ferrite in high-strength low-alloy (HSLA) steels possesses a significant challenge, where both nanoindentation and chemical analyses do not achieve an adequate phase classification due to the similar mechanical and chemical properties of both constituents. Here, the kernel average misorientation from electron backscatter diffraction (EBSD) was implemented into a Matlab code to differentiate and quantify the microstructural constituents. Correlative electron channeling contrast imaging (ECCI) validated the automated phase classification results and was further employed to investigate the effect of the grain tolerance angle on classification. Moreover, ECCI investigations highlighted that the grain structure of HSLA steels can be subdivided into four grain categories. Each category contained a different nanohardness or substructure size that precluded a nanoindentation-based phase classification. Consequently, the automated EBSD classification approach based on local misorientation achieved a reliable result using a grain tolerance angle of 5°.

Prevalence of vitamin D deficiency in pregnant women in India is high. There have been case reports from India of neonatal tetany and vitamin D deficiency in breast-fed infants. India initiated the calcium and vitamin D supplementation programmes for pregnant women a decade ago. There is a need to assess compliance with calcium and vitamin D supplementation and impact of supplements on vitamin D levels in pregnant women.Women attending antenatal clinic in an urban maternity centre who fulfilled the eligibility criteria and were willing to participate in the study were enrolled. They were given one month’s supply of supplements, and form for recording compliance and side effects and were followed up every month. Blood samples were drawn at enrolment and after three months of supplementation and plasma vitamin D levels were estimated.Two third of the women had vitamin D level below 20 ng/ml at enrolment There was excellent compliance with supplementation; women who were followed up consumed 94% of the tablets provided. None of the women had clinical signs suggestive of vitamin D deficiency or any major obstetric problems; their offsprings were healthy. A third of the pregnant women continued to have low vitamin D levels after three months supplementation.The current dose of supplements appears to be inadequate to correct the vitamin D levels in deficient individuals. There is a need to undertake studies to find out the optimal dose of vitamin D supplementation which corrects vitamin D deficiency as assessed by maternal vitamin D levels.

Prenatal screening with maternal biochemical dual and quadruple markers, along with reflex testing using karyotyping, and non-invasive prenatal testing via next-generation sequencing (NIPT-NGS) were evaluated to determine the clinical validity of Metropolis Pregascreen reflex testing approach among Indian women. Retro-prospective data of 51574 Indian women undergoing maternal marker screening from January 2021 to March 2022 were analysed at Metropolis Healthcare Limited, India. First and second-trimester prenatal screening were performed using Roche and Siemens platforms. Risk calculated using SSDW and PRISCA software, USG findings and biochemical values were incorporated. NIPT reflex testing was carried out using Thermo Ion torrent S5 NGS systems, while karyotyping on chronic villus sampling or amniocentesis. Total 51574 women opted for the combined biochemical markers test (dual and quadruple), 1394 cases (2.70%) and 50180 cases (97.28%) were screened as high-risk and low-risk, respectively. Of the total high-risk cases, 483 women (34.65%) opted for NIPT, while 25 (1.79%) opted for karyotyping reflex testing. Dual marker 92% and quadruple marker 94% of high risk cases were reclassified as low risk post NIPT, while dual marker 91% and quadruple marker 93% of high risk cases were reclassified as low risk post karyotyping. Possibility of ruling out false positive is almost equal with NIPT and karyotyping. Hence, invasive screening could be avoided as first line of investigation.Metropolis Pregascreen reflex testing with NIPT assisted in the delineation of actual high risk cases for accurate and safer diagnosis.

Along with the right total hysterectomy sample both cervices were delivered. Frozen section showed a simple hyperplasia without atypia in left horn and hyperplasia with foci of intraepithelial neoplasia in right horn, Final histopathology further confirmed the same report. : It's important to have a full awareness of any potential related deformities when managing patients with Mullerian defects and irregular uterine haemorrhage. To prevent urological problems and surgical mishaps, a thorough preoperative evaluation, meticulous surgical investigation, and multidisciplinary approach may be required.
Gigantism in Earthworms: A Note on Gigantic Eisenia and Dendrobaena
Authors: Domínguez Jorge , Guimaraěs Afrânio 
Published: August 2023

Earthworms are iteroparous organisms with indeterminate growth, i.e. they continue to increase in size throughout their life and after completion of sexual development. Terrestrial oligochaetes vary greatly in size. Depending on the species, adult earthworms can reach between 10 mm and 3 m in length and between &amp;lt;1 mm and &amp;gt;25 mm in width, with most being of length 5-15 cm. Among the more than 7000 species described to date, very few (~20) reach lengths greater than 1 m. The longest earthworm on record is Amynthas mekongianus, which is found in the mud banks of the Mekong River in Southeast Asia and which reaches almost 3 m in length. It is about the same size as Megascolides australis, the ‘Giant Gippsland Earthworm’. These atypically giant earthworm species remain a scientific curiosity in terms of their biology, but they cannot be considered cases of gigantism. Gigantism occurs when organisms are much larger than normal or exhibit excessive growth. Earthworms obtain energy from the organic matter on which they feed, and their growth mainly depends on the quality of the resource and on the species, as well as on food availability, environmental factors, which can directly or indirectly affect growth by modifying food availability, and other factors such as competition. This is particularly evident in earthworms, which display indeterminate growth and large species-dependent variations in size. The biology, life cycle and growth and reproduction rates of Eisenia fetida (Savigny 1826) and Eisenia andrei (Bouché 1972), the earthworm species most commonly used in vermicomposting and vermiculture, have been widely reported. Here we present details of the enormous growth of individual specimens of Eisenia andrei and Dendrobaena hortensis reared under particular culture conditions and fed a special diet. Individuals almost 20 times the average weight of individuals of the species have been obtained. Possible explanations for this interesting phenomenon are discussed.
