Post Pregnancy Severe Spinal Osteoporosis with Multiple Vertebral Fractures and Kyphoscoliosis in a Multigravida: A Rare Case with Management

Shailesh Hadgaonkar,Kunal Chandrakant Shah,Hrutvij Bhatt,Ashok Shyam,Parag Sancheti 대한척추외과학회 2015 Asian Spine Journal Vol.9 No.4

Osteoporosis associated with pregnancy and lactation is a less commonly known condition and often overlooked. The prevalence, exact aetiology and its pathogenesis are unknown. It is commonly seen in first three months after delivery in primigravida. It is often undiagnosed because of it not suspected n and X-rays and densitometry are avoided if possible during pregnancy and lactation. If missed, it can lead to osteoporotic fractures and disability. In this paper, we report a case of a 24-year-old multigravida 4 months after pregnancy with multiple vertebral compression fractures and kyphoscoliosis. Her metabolic workup was normal but bone densitometry revealed severe osteoporosis of the dorso-lumbar spine. Immediate weaning and antiresorptives like bisphosphonates and teriparatide are used as first line drugs to manage postpartum spinal osteoporosis. Our patient presented at 4 month lactation and did not want to wean her infant, so she was treated with total contact orthosis and took vitamin D and calcium. The pain was relieved within 3 months but there was no improvement in bone density. After eight months when the infant was weaned, she was treated with teriparatide. After one year of teriparatide therapy, there were no new fractures and densitometry scores improved.

The current need for eco-friendly approaches for farming, while ensuring the health and productivity of crops is increasing rapidly. Research on the biological control of white root rot disease caused by a soil-borne pathogen, Rosellinia necatrix is limited in pears compared to that in apple and avocado. The severity of the disease caused by Rosellinia necatrix makes it the most harmful fungal pathogen infecting the economical fruit tree species and is one of the main limiting factors in pear farming. To control this disease growers have to depend on chemical treatments. However, rising public concern about environmental pollution and the harmful effects of chemicals in humans and animals has facilitated the search for novel and environmentally friendly disease control methods. Most of the biocontrol agents have been tested in other plant system along with that most of the studies have been focused in vitro or in confined greenhouse experiments, and verification of their potentials under field conditions is still remains an another question. Soil solarization fulfills the requirements for successful control of a soilborne pathogen in existing orchard as: there is no damage to trees, the inoculum is controlled to a considerable depth and delayed soil reinfestation. Hot water treatment can be used in established orchard or to disinfect plant material used for propagation and to kill the pathogen within the rhizosphere. Weeds on the floors of pear may serve as reservoirs to alternative hosts for pathogens and their vectors.

Shailesh Sawant,Eu Ddeum Choi,Janghoon Song,Ho-Jin Seo 한국원예학회 2021 한국원예학회 학술발표요지 Vol.2021 No.10

Pear is one of the most important commercial crops of India and is grown in different parts of the country. India is one of the main pear producers in the world, and its cultivation area is almost doubled in the last 20 years. Pear cultivation in India is mainly occurred from foothills to high hills experiences about five hundred to thousand five hundred chilling hours throughout the year. The pear is mainly grown in northern states of Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Punjab, and in south India Tamilnadu state. The north-eastern hills region, comprising of the states of Arunachal Pradesh, Nagaland, Mizoram, Meghalaya, and Sikkim also grows on a limited scale. Overall northwestern and eastern hills part of India provide a favorable climatic condition for growing a wide range of pears and their cultivation. India import different variety of pears from 14 countries around the word. India primarily imports green and red-skinned Anjou pears varieties from the United States with Green Anjou the favored variety. However, the production of pear in India remained challenging may be due to the attack of pests and disease incidence. The important insect and mite pest of Indian pear orchards are codling moth, pear psylla, mites, and borers.

Current Status and Future Prospects of White Root Rot Management in Pear Orchards: A Review

Shailesh S,Sawant,Eu Ddeum Choi,Janghoon Song,Ho-Jin Seo 한국식물병리학회 2021 식물병연구 Vol.27 No.3

The current social demand for organic, sustainable, and eco-friendly approaches for farming, while ensuring the health and productivity of crops is increasing rapidly. Biocontrol agents are applied to crops to ensure biological control of plant pathogens. Research on the biological control of white root rot disease caused by a soil-borne pathogen, Rosellinia necatrix, is limited in pears compared to that in apple and avocado. This pathogenic fungus has an extensive host range, and symptoms of this disease include rotting of roots, yel- lowing and falling of leaves, wilting, and finally tree death. The severity of the disease caused by R. necatrix, makes it the most harmful fungal pathogen infecting the economical fruit tree species, such as pears, and is one of the main limiting factors in pear farming, with devastating effects on plant health and yield. In addi- tion to agronomic and cultural practices, growers use chemical treatments to control the disease. However, rising public concern about environmental pollution and harmful effects of chemicals in humans and ani- mals has facilitated the search for novel and environmentally friendly disease control methods. This review will briefly summarize the current status of biocontrol agents, ecofriendly methods, and possible approaches to control disease in pear orchards.

Yeats’s A Vision and Sri Aurobindo’s Life Divine : The Essence of Poetry

Shailesh Bagdane 한국예이츠학회 2021 한국예이츠 저널 Vol.65 No.-

예이츠와 아우로빈도 고시의 작품은 삶의 후반기에 시를 위한 여러 해 의 주제, 출처 및 구조로 남아 있었다. 예이츠는 마지막 시기까지 시적 위대함을 추구 했고 아우로빈도 고시는 초의식과 합쳐질 때까지 서사시를 쓰고 영혼의 변화, 영혼의 여정에 대해 몰두했다. 예이츠의 『환상록』은 달의 28위상과 인간 마음과 문명의 원리 를 나타낸 기하학적 상징이며, 아우로빈도 고시의 『성스러운 생명』은 영적 진화, 초심 적 의식을 향한 초인간적인 분투의 두 방법을 사용하여 물질을 통한 마음의 고양, 초 월적 마음, 초의식, ‘존재, 의식, 행복’로의 고양을 추구한다. 예이츠의 철학서 『환상록』은 탁월한 시적 성취를 위한 신화 체계이라면 아우로빈도 고시의 『성스러운 생명』은 궁극적인 현실을 달성하기 위한 미로이다. 삶은 계속되고, 인간이 죽을 때 삶이 성장 하기 위해 호흡이 필요하고, 육체의 기관은 삶을 위해 더 이상 유용하지 않고, 육체의 기능이 상실될 때 삶은 물러난다. The works of Yeats and Sri Aurobindo offer the perennial theme, source, and structure for poetry, particularly in the later phases of their lives: Yeats’s last phase makes him create his great poetry while Sri Aurobindo’s helps him write his great epic by looking into the transformation of soul, a journey of soul until it merges with the Supermind. Yeats’s A Vision is geometrical symbolism showing 28 phases of Moon and the Principles and faculties of human and civilization, while Sri Aurobindo’s Life Divine is about spiritual evolution, efforts of superhuman kind towards super mental consciousness by two ways: one to lift mind through matter, to Overmind, and then to Supermind, sat-chit-ananda. Yeats’s A Vision is a system, the myths for his poetry with which Yeats is to get to excellent poetic achievement; Sri Aurobindo’s Life Divine based on eternal and spiritual exploration achieves ultimate reality. Life is continuous: breath is necessary for life; when man is dead and his body’s organism is no longer active, life withdraws.

Exploring Small-fruit Production in India: Present Landscape and Future Opportunities

Shailesh S. Sawant,Byulhana Lee,Janghoon Song,Ho-Jin Seo 한국국제농업개발학회 2023 韓國國際農業開發學會誌 Vol.35 No.2

In recent years, India has consistently increased its production of small fruits. India is the second-largest producer of fruits and vegetables globally, with a diverse range of small fruits grown across the country. Small fruits, such as kiwifruit and blueberries, are in high demand due to the growing popularity of healthier food options and increased awareness of their associated health benefits. However, the current status of small fruit production in India is substantially lower than that of other fruit crops. Nonetheless, there has been a growing interest in small fruit production, particularly in regions with suitable climatic conditions. Currently, only two types of small fruit are commercially produced in India: grapes and Indian jujube/ber. Three other fruit types, strawberries, blueberries, and kiwi, have production areas of less than 10,000 ha each. Despite the growing interest in small fruit production, several challenges, such as the lack of good planting materials, productivity issues, lack of packaging facilities, and marketing networks for farmers, need to be addressed to enhance the prospects for small fruit production in India. Future studies should focus on several areas to overcome these challenges. Firstly, it is crucial to understand the specific resource constraints that small fruit producers face and develop strategies to improve their access to essential resources, including planting materials, land, water, and financial support. Secondly, innovative marketing strategies tailored to the unique characteristics of small fruit production in India should be employed to expand domestic and international market opportunities. Lastly, adopting appropriate technologies and sustainable production practices is necessary to improve productivity and mitigate environmental impacts. Overall, the prospects for small fruit production in India appear promising, given the growing demand for healthier food options and the expanding domestic and international markets for small fruits.
