Cryptochromes (CRYs) and UV RESISTANCE LOCUS 8 (UVR8) photoreceptors perceive UV-A/blue (315-500 nm) and UV-B (280-315 nm) radiation in plants, respectively. While the roles of CRYs and UVR8 have ...been studied in separate controlled-environment experiments, little is known about the interaction between these photoreceptors. Here, Arabidopsis wild-type Ler, CRYs and UVR8 photoreceptor mutants (uvr8-2, cry1cry2 and cry1cry2uvr8-2), and a flavonoid biosynthesis-defective mutant (tt4) were grown in a sun simulator. Plants were exposed to filtered radiation for 17 d or for 6 h, to study the effects of blue, UV-A, and UV-B radiation. Both CRYs and UVR8 independently enabled growth and survival of plants under solar levels of UV, while their joint absence was lethal under UV-B. CRYs mediated gene expression under blue light. UVR8 mediated gene expression under UV-B radiation, and in the absence of CRYs, also under UV-A. This negative regulation of UVR8-mediated gene expression by CRYs was also observed for UV-B. The accumulation of flavonoids was also consistent with this interaction between CRYs and UVR8. In conclusion, we provide evidence for an antagonistic interaction between CRYs and UVR8 and a role of UVR8 in UV-A perception.
Introduction
Amid the second wave of COVID 19 India witnessed a surge of mucormycosis cases. This worsened the already existing health emergency. India a diabetic capital had all the favourable ...factors to support the growth of black fungus. This study was conducted with objectives of ascertaining patient characteristics, clinical type of mucormycosis, predisposing factors, predictors of survival and long term outcome of survivors.
Materials and methods
An ambispective study of COVID 19 associated mucormycosis patients admitted in mucor ward of tertiary care hospital between May 2021- August 2021 was done. Study was approved by Institute Ethical Committee. Demographic characteristics, presence of risk factors, clinical sign and symptoms, mode of diagnosis, treatment given, final outcome and long term follow up for a period of 1 year from discharge was done.
Results
367 CAM patients were included in the study. 72.5%(
n
= 266) were men and 27.5% (
n
= 101) were females. Mean age group was 51.3 years (SD 12.4 years). Most important comorbidity was diabetes(
n
= 320,87.2%), followed by cardiovascular disease (
n
= 68, 18.5%) and hypertension (
n
= 58,15.8%). Other predisposing factors were use of oxygen (
n
= 367,100%), antibiotics(
n
= 213,58%) and steroids (
n
= 272, 74.1%). Dexamethasone was the most commonly used steroid (
n
= 218,59.4%). Rhino orbital cerebral mucormycosis was the most common type. 83.7% patients (
n
= 307) survived and 16.3% (
n
= 60) succumbed to illness. Kaplan Meir survival analysis curve showed use of insulin (
p
= 0.025), early debridement (
p
< 0.05) significantly increased survival rate. Similarly patients with lesions involving, face (
p
< 0.05) and nose (
p
= 0.014) had much better outcome as compared to disseminated forms. Only 96 patients remained in follow up. Of these patients no significant alteration in metabolic profile was noted and they remained euglycemic on oral hypoglycaemics.
Conclusion
Early debridement and insulin use are keys to improved survival. Oxygen, Steroids and antibiotics are the risk factors for mucormycosis. Diabetes is the most important comorbidity.
Roots enable the plant to survive in the natural environment by providing anchorage and acquisition of water and nutrients. In this study, root architectural traits of 153 mungbean genotypes were ...compared under optimum and low phosphorus (P) conditions. Significant variations and medium to high heritability were observed for the root traits. Total root length was positively and significantly correlated with total root surface area, total root volume, total root tips and root forks under both optimum P (r = 0.95, r = 0.85, r = 0.68 and r = 0.82 respectively) and low P (r = 0.95, r = 0.82, r = 0.71 and r = 0.81 respectively). The magnitudes of the coefficient of variations were relatively higher for root forks, total root tips and total root volume. Total root length, total root surface area and total root volume were major contributors of variation and can be utilized for screening of P efficiency at the seedling stage. Released Indian mungbean varieties were found to be superior for root traits than other genotypic groups. Based on comprehensive P efficiency measurement, IPM-288, TM 96-25, TM 96-2, M 1477, PUSA 1342 were found to be the best highly efficient genotypes, whereas M 1131, PS-16, Pusa Vishal, M 831, IC 325828 were highly inefficient. Highly efficient genotypes identified would be valuable genetic resources for P efficiency for utilizing in the mungbean breeding programme.
COVID-19, a global pandemic that led to increased morbidity and mortality worldwide since its outcome at the end of the year 2019. A newly discovered variant of severe acute respiratory distress ...syndrome coronavirus-2 (SARS-CoV-2) was the arbitrator for spreading the syndrome by droplet transmission causing multi-organ failure in many occasions. A post-infection-pro-diabetic disposition was found evident in this study with the persistence of hepato-pancreatic aberrations in respect of reference range of tissue specific bio-markers in hospital admitted COVID-19 cases. The results of this study show that hyperglycemia is a risk factor in precipitating disease oriented complications to the patients with COVID-19 disease. A post-infection follow- up on glycemic-index and related complexities is a vital need to the COVID-19 infected convalescent subjects. Implementation of guidelines on social measure and awareness of anti-viral interventions may be the only way to prevent COVID-19 transmission.
Immunofluorescence on human epithelial type 2 cells is the standard screening assay for the detection of antinuclear antibodies (ANA). Cytoplasmic speckled patterns are a common finding. However, the ...less commonly reported ones include the cytoplasmic fibrillar patterns on indirect immunofluorescence technique (IIFT). The cytoplasmic fibrillar patterns include the cytoplasmic linear (AC-15), cytoplasmic filamentous (AC-16), and cytoplasmic segmental (AC-17). We report a case of cytoplasmic linear (F-actin) detected through IIFT during ANA screening in a 77-year-old man and later reconfirmed on liver mosaic biochip through IIFT on vascular smooth muscle substrate (VSM-47) without features suggestive of anti-smooth muscle antibody involvement post-complementary and alternative medicine therapy initiation.
The endoplasmic reticulum (ER) is the site for protein synthesis, its folding and secretion. An intricate set of signalling pathways, called UPR pathways, have been evolved by ER in mammalian cells, ...to allow the cell to respond the presence of misfolded proteins within the ER. Breaching of these signalling systems by disease oriented accumulation of unfolded proteins may develop cellular stress. The aim of this study is to explore whether COVID-19 infection is responsible for developing this kind of endoplasmic reticulum related stress (ER-stress). ER-stress was evaluated by checking the expression of ER-stress markers e.g. PERK (adapting) and TRAF2 (alarming). ER-stress was correlated to several blood parameters viz. IgG, pro- and anti-inflammatory cytokines, leukocytes, lymphocytes, RBC, haemoglobin and PaO

ratio (ratio of arterial oxygen partial pressure to fractional inspired oxygen) in COVID-19 affected subjects. COVID-19 infection was found to be a state of protein homeostasis (proteostasis) collapse. Changes in IgG levels showed very poor immune response by the infected subjects. At the initial phase of the disease, pro-inflammatory cytokine levels were high and anti-inflammatory cytokines levels were low; though they were partly compromised at later phase of the disease. Total leukocyte concentration increased over the period of time; while percentage of lymphocytes were dropped. No significant changes were observed in cases of RBC counts and haemoglobin (Hb) levels. Both RBC and Hb were maintained at their normal range. In mildly stressed group, PaO

ratio (oxygenation status) was in the higher side of normal range; whereas in other two groups the ratio was in respiratory distress syndrome mode. Virus could induce mild to severe ER-stress, which could be the cause of cellular death and systemic dysfunction introducing fatal consequences.

Mungbean (Vigna radiata L.) is an important food grain legume, but its production capacity is threatened by global warming, which can intensify plant stress and limit future production. Identifying ...new variation of key root traits in mungbean will provide the basis for breeding lines with effective root characteristics for improved water uptake to mitigate heat and drought stress. The AVRDC mungbean mini core collection consisting of 296 genotypes was screened under modified semi-hydroponic screening conditions to determine the variation for fourteen root-related traits. The AVRDC mungbean mini core collection displayed wide variations for the primary root length, total surface area, and total root length, and based on agglomerative hierarchical clustering eight homogeneous groups displaying different root traits could be identified. Germplasm with potentially favorable root traits has been identified for further studies to identify the donor genotypes for breeding cultivars with enhanced adaptation to water-deficit stress and other stress conditions.
Introduction
Uttar Pradesh ranks first in India as far as trauma deaths are concerned with 40% of victims under 18 years of age. In spite of such high mortality and morbidity no national portal for ...trauma registry data exists. This study was conducted to evaluate the profile of injured pediatric patients, to provide baseline knowledge for further research, management and development of pediatric injury prevention programmes.
Methods
A retrospective observational study was conducted in the only Level 1Trauma Centre of the most populous state of India. Children aged less than 18 years of age admitted to the trauma centre were analysed for mechanism, type and severity of injury, the mode of management and outcome.
Result
In a 2 year period 916 children were admitted and their data analysed. Most were boys (73%) and the most common age group was 12–18 years. Half of injuries were caused by road traffic accidents, and blunt injuries were commonest. Blunt abdominal trauma then head injury were the commonest areas injured; 20% of children had life-threatening injuries. Nearly half (47%) had moderate to severe trauma according to the Pediatric Trauma Score. 507 patients (55.4%) were managed conservatively and 409 children (44.6%) required surgery; 657 (71%) were successfully discharged and 39 children (4.25%) unfortunately died.
Conclusion
This study identifies the need for dedicated trauma registries, training of trauma team according to standard operating procedures, the development of paramedical teams for in-the-field management of patients and development of injury prevention programmes according to both age and gender.
Abstract
Laboratory investigations for any suspected case of solitary plasmacytoma of bone include routine biochemical and hematological investigations along with β2-microglobulin, electrophoresis of ...serum protein and/or 24-hour urine protein, serum protein immunofixation (IFE), and nephelometric quantification of total immunoglobulin isotype and serum free light chain levels. Bone marrow aspirate and trephine biopsy are mandatory to confirm the absence of clonal plasma cells (for solitary plasmacytoma) or the presence of less than 10% clonal cells (solitary plasmacytoma with minimal bone marrow involvement). Imaging studies such as X-ray, computed tomography (CT), magnetic resonance imaging, and positron emission tomography/CT should be used to complement laboratory tests in diagnosis, staging, and defining the local extent of the plasmacytoma. However, guidelines regarding choice of technique for the detection of M band when monitoring a follow-up case of operated plasmacytoma are still not clear. Through this case study, we try to highlight the role of IFE in a follow-up case of operated solitary plasmacytoma of the bone.
