Response of Strawberry plant (Fragaria ananassa Duch.) to inoculation with arbuscular mycorrhizal fungi and Trichoderma viride

The present paper represents the positive role of Arbuscular Mycorrhizal (AM) fungi as biofertilizers in strawberry. Experiments were carried out to assess the effectiveness of Trichoderma viride and AM fungi (Glomus mosseae and Acaulospora laevis) alone or in combination, on the growth and biomass production of strawberry. After 120 days, dual inoculation of A. laevis + T. viride showed maximum increase in plant height (30.5±0.3), fresh shoot weight (10.16±0.20), dry shoot weight (2.82±0.02), fresh root weight (6.70±0.10), total chlorophyll (0.841±0.05) and phosphorus content in root (1.13±0.02) as compared to control. However root colonization and AM spore number were maximum in G. mosseae + A. lavies (90.76±1.32) and in G. mosseae (211.16±2.56) respectively as compared to uninoculated plants. Triple inoculation of G. mosseae + A. laevis + T. viride (12.33± 057) was effective in increasing the leaf area

CONSERVATIVE MANAGEMENT OF ACUTE LUMBAR DISC HERNIATION WITH ASSOCIATED RADICULOPATHY: A STUDY

Objective: Acute disc herniation (DH) is a common cause of low back pain (LBP). It ranks fifth in the category of diseases in terms of cost of hospital care. It has higher indirect costs due to absenteeism from work and disability than any other disease. The present study was performed to assess the clinical outcomes of non-surgically treated LBP patients after 6 months of follow-up. Methods: The present study was prospective study which was performed on 450 lumbar radicular patients visiting the neurosurgery outpatient department having clinical signs and symptoms of acute lumbar DH of less than 3 month duration. Their diagnosis was confirmed by magnetic resonance imaging. The patients were treated conservatively during 6 months. Pain and disability were assessed by visual analog scale (VAS) and Oswestry disability questionnaire, respectively. Results: About 135 (30%) female and 315 (70%) male participated in the study. During the follow-up period, 27 (06%) patients (21 male and 6 female) showed poor response to conservative treatment and motor weakness and underwent surgical intervention. A significant improvement in the VAS Score was seen after 6 months of conservative treatment than initial evaluation of patients (3.12±1.84, 7.1±1.43, p=0.00). Furthermore, significant improvement in disability score of patients was seen in follow-up period (25.82±16.92, 53.66±17.66; p=0.00). Conclusion: Results of our study showed that conservative treatment in patients of acute lumbar DH have significant improvement in pain relief and disability without any notable side effect

Drug utilization pattern in an intensive care unit setting in Eastern India

Background: The intensive care unit (ICU) is a setting where a large number of drugs are administered to patients, most of them critically ill and suffering from multiple complications, making the costs of hospitalization and drug treatment high. There is a dearth of information on drug utilization in ICUs in Eastern India. The present study was undertaken to evaluate the drug utilization pattern in an ICU setting in Eastern India. The objective was to monitor, evaluate, and suggest modifications in the prescribing pattern of ICU drugs.Methods: A retrospective analysis of the case records of patients admitted to the ICU of a multispecialty hospital in Eastern India during the time period from January 2015 to June 2015 was carried out. The demographic profile of the patients, drug utilization pattern and defined daily dose (DDD)/100 bed-days of the commonly used drugs in the ICU were studied.Results: A total of 275 patients were evaluated consisting 61% male patients. Most common causes for admission to the ICU were a cerebrovascular accident, chronic kidney disease, and road traffic accident. An average number of drugs per patient was 10.5. Commonly prescribed drug classes were the antimicrobial agents (AMAs) in 96% patients followed by gastrointestinal drugs. Ceftriaxone was the most commonly used AMA (41.5% patients), having a drug consumption of 35.1 DDD/100 bed-days during the study period.Conclusions: An antibiotic use policy should be framed and followed to curb the excessive use of AMAs. Formation of a multidisciplinary team to oversee drug use will be helpful to make the drug utilization in the ICU rational

Evaluation of association of vitamin D level with types of proximal femoral fractures in elderly patients

Background: Proximal femoral fractures are very common in elderly patients. These fractures are thought to be associated with osteoporosis. Vitamin D is a possible risk factor for osteoporosis. So, this study was done to evaluate the association of serum vitamin D level with types of femoral fractures in elderly patients.Methods: The study was done between September 2013 to August 2016, 75 patients with age >60 years (male and female both) with proximal femoral fractures were studied. Serum 25-hydroxy vitamin D, calcium, phosphate, alkaline phosphatase levels, liver function test, renal function test, hemoglobin and complete blood counts of all the patients were assessed.Results: On assessment of serum vitamin D in proximal femoral fracture in elderly patients, it shows an increase incidence of proximal femoral fractures in patients with low serum vitamin D level. Fracture of neck of femur was most common among all. Type of fracture has no significant statistical relationship with serum vitamin D levels.Conclusions: Osteoporosis and serum vitamin D level depends on age and sex of the patient. But type of proximal femoral osteoporotic fracture has no association with either grade of osteoporosis or serum vitamin D level

Structural phase transitions in perovskite BaCeO3 with data mining and first-principles theoretical calculations

Several experiments conducted over decades have revealed that the perovskite-structured BaCeO3 goes through a series of temperature-induced structural phase transitions. However, it has been frequently observed that the number of phases and the sequence in which they appear as a function of temperature differ between experiments. Insofar as neutron diffraction and Raman spectroscopy experiments are concern, four structures are well characterized with three transitions: Pnma to Imma [563 K] to R-3c [673 K] to Pm-3m [1173 K]. In contrast, thermoanalytical methods showed multiple singularities corresponding to at-least three more structural transitions at around 830 K, 900 K, and 1030 K. In account of these conflicting experimental findings, we computed free energy phase diagram for BaCeO3 employing crystal structure data mining in conjunction with first principles electronic structure and phonon lattice dynamics. A total of 34 polymorphs have been predicted, the most stable of which follows the Glazer classification of the perovskite tilt system. It has been predicted that the Cmcm and P4/mbm phases surpass Pnma at 666 K and 1210 K, respectively. At any temperature, two alternate tetragonal phases (P42/nmc and I4/mcm) are also found to be 20 to 30 meV less favored than the Pnma. While the calculated stability order of the predicted polymorphs is in acceptable agreement with the results of neutron diffraction, the transitions observed in thermoanalytical studies could be ascribed to the development of four novel phases (Cmcm, P4/mbm, P42/nmc, and I4/mcm) at intermediate temperatures. However, we analyze that the R-3c phase predominantly stabilized over a broad temperature field, masking all subsequent phases up until the cubic Pm-3m. Consequently, the novel phases predicted to occur in thermoanalytical studies are only fleetingly metastable.Comment: 20 pages, 5 figures, 1 tabl

Sustainable production of Saussurea costus under different levels of nitrogen, phosphorus and potassium fertilizers in cold desert region of Western Himalaya

IntroductionSaussurea costus, an important critically endangered medicinal herb native to the Himalayan region, is commonly used in various ailments, viz. asthma, ulcer, inflammation, and stomach problems. In the international market, the dry roots and essential oil of S. costus has become an important drug. The lack of appropriate fertilizer dose recommendations is one of the limiting factors for its ex-situ conservation and large-scale cultivation, as plant nutrition is vital in determining crop growth and productivity. The study aimed to understand the comparative impact of different levels of fertilizer nutrients on growth, dry root and essential oil yield, and essential oil profile of S. costus.MethodsA field experiment was conducted in Himachal Pradesh, India's cold desert region (Lahaul valley), during 2020-21. The experiment comprised three levels of nitrogen (60, 90, and 120 kg ha-1), three levels of phosphorus (20, 40, 60 kg ha-1), and two levels of potassium (20 and 40 kg ha-1) in a factorial randomized block design.ResultsThe fertilizer application had an immense effect on growth attributes, root yield attributes, dry root yield, and essential oil yield over control. The treatment combination N120, P60, and K40 had the largest effect on the plant height, number of leaves per plant, leaf length and width, root length and diameter, dry matter per plant, dry root yield, and essential oil yield. However, the results were at par with the treatment comprising N90, P40, and K20. Dry root yield increased by 108.9%, and essential oil yield increased by 210.3% with fertilizer applications over unfertilized plots. The regression curve shows an increasing trend in dry root yield till N90, P40, and K20; after that, it nearly stabilized. The heat map showed that applying fertilizer significantly affected the chemical constituents of S. costus essential oil. Similarly, the plots fertilized with the highest level of NPK recorded the utmost value of available N, P, and K, as compared to unfertilized plots.DiscussionThe results emphasize that for sustainable cultivation of S. costus, the application of N90, P40, and K20 combinations is the most suitable one

Genetic resources and breeding approaches for improvement of amaranth (Amaranthus spp.) and quinoa (Chenopodium quinoa)

Nowadays, the human population is more concerned about their diet and very specific in choosing their food sources to ensure a healthy lifestyle and avoid diseases. So people are shifting to more smart nutritious food choices other than regular cereals and staple foods they have been eating for a long time. Pseudocereals, especially, amaranth and quinoa, are important alternatives to traditional cereals due to comparatively higher nutrition, essential minerals, amino acids, and zero gluten. Both Amaranchaceae crops are low-input demanding and hardy plants tolerant to stress, drought, and salinity conditions. Thus, these crops may benefit developing countries that follow subsistence agriculture and have limited farming resources. However, these are underutilized orphan crops, and the efforts to improve them by reducing their saponin content remain ignored for a long time. Furthermore, these crops have very rich variability, but the progress of their genetic gain for getting high-yielding genotypes is slow. Realizing problems in traditional cereals and opting for crop diversification to tackle climate change, research should be focused on the genetic improvement for low saponin, nutritionally rich, tolerant to biotic and abiotic stresses, location-specific photoperiod, and high yielding varietal development of amaranth and quinoa to expand their commercial cultivation. The latest technologies that can accelerate the breeding to improve yield and quality in these crops are much behind and slower than the already established major crops of the world. We could learn from past mistakes and utilize the latest trends such as CRISPR/Cas, TILLING, and RNA interference (RNAi) technology to improve these pseudocereals genetically. Hence, the study reviewed important nutrition quality traits, morphological descriptors, their breeding behavior, available genetic resources, and breeding approaches for these crops to shed light on future breeding strategies to develop superior genotypes

Vascular patterns on narrow band imaging (NBI) video bronchoscopy of lung cancer patients and its relationship with histology: an analytical cross-sectional study

Introduction: Narrow band imaging (NBI) video bronchoscopy provides better visualisation of submucosal vascular patterns in malignant airway lesions compared to white light bronchoscopy. This analytical cross-sectional study was aimed to look for any relationship between these NBI vascular patterns and the histologic type of lung cancer.Material and methods: After screening 78 patients with suspected lung cancer, 53 subjects underwent video bronchoscopy. Thirty-two patients showing abnormal bronchial mucosa or endobronchial growth with any of the NBI vascular patterns on bronchoscopy were enrolled in the study. These abnormal areas were then biopsied and sent for histologic examination.Results: NBI bronchoscopy revealed a dilated tortuous vascular pattern in 54.8% of the patients, a non-specific pattern in 32%, a dotted pattern in 9.7% and an abrupt ending vessels pattern in 3.2% of the patients. We did not find any statistically significant relationship between a dilated tortuous pattern and squamous-cell carcinoma (p = 0.48), adenocarcinoma (p = 0.667) or small-cell carcinoma (p = 1); between a dotted pattern and squamous-cell carcinoma (p = 1), adenocarcinoma (p = 0.54) or small-cell carcinoma (p = 1), and between an abrupt ending capillary pattern and squamous-cell carcinoma (p = 1), adenocarcinoma (p = 1) or small-cell carcinoma (p =1).Conclusion: No relationship exists between NBI vascular patterns and the histology of lung cancer. Endobronchial lesions showing any vascular pattern on NBI needs to be adequately sampled for proper histologic and molecular studies in lung cancer patients
