Prospects of microgreens as budding living functional food: Breeding and biofortification through OMICS and other approaches for nutritional security.

Nutrient deficiency has resulted in impaired growth and development of the population globally. Microgreens are considered immature greens (required light for photosynthesis and growing medium) and developed from the seeds of vegetables, legumes, herbs, and cereals. These are considered "living superfood/functional food" due to the presence of chlorophyll, beta carotene, lutein, and minerals like magnesium (Mg), Potassium (K), Phosphorus (P), and Calcium (Ca). Microgreens are rich at the nutritional level and contain several phytoactive compounds (carotenoids, phenols, glucosinolates, polysterols) that are helpful for human health on Earth and in space due to their anti-microbial, anti-inflammatory, antioxidant, and anti-carcinogenic properties. Microgreens can be used as plant-based nutritive vegetarian foods that will be fruitful as a nourishing constituent in the food industryfor garnish purposes, complement flavor, texture, and color to salads, soups, flat-breads, pizzas, and sandwiches (substitute to lettuce in tacos, sandwich, burger). Good handling practices may enhance microgreens'stability, storage, and shelf-life under appropriate conditions, including light, temperature, nutrients, humidity, and substrate. Moreover, the substrate may be a nutritive liquid solution (hydroponic system) or solid medium (coco peat, coconut fiber, coir dust and husks, sand, vermicompost, sugarcane filter cake, etc.) based on a variety of microgreens. However integrated multiomics approaches alongwith nutriomics and foodomics may be explored and utilized to identify and breed most potential microgreen genotypes, biofortify including increasing the nutritional content (macro-elements:K, Ca and Mg; oligo-elements: Fe and Zn and antioxidant activity) and microgreens related other traits viz., fast growth, good nutritional values, high germination percentage, and appropriate shelf-life through the implementation of integrated approaches includes genomics, transcriptomics, sequencing-based approaches, molecular breeding, machine learning, nanoparticles, and seed priming strategiesetc.

Dexmedetomidine versus clonidine as an adjuvant to local anaesthetic in brachial plexus blocks: a meta-analysis of randomised controlled trials.

OBJECTIVE: This meta-analysis aimed to compare the efficacy and safety of dexmedetomidine and clonidine as an adjuvant to local anesthetics in BPBs. METHODS: Two investigators independently searched databases to identify all RCTs comparing the efficacy and/or safety of dexmedetomidine and clonidine as an adjuvant to local anesthetics in BPBs. All outcomes were pooled using the inverse variance method with a random-effect model. An I2 test was used to assess heterogeneity. The source of heterogeneity was explored through meta-regression. The quality of the evidence was assessed using the GRADE approach. RESULTS: Out of 123 full texts assessed, 24 studies (1448 patients) were included in the analysis. As compared to clonidine, dexmedetomidine groups showed significantly longer sensory block duration (MD = 173.31; 95% CI 138.02‒208.59; I2 = 99%; GRADE approach evidence: high); motor block duration (MD = 158.35; 95% CI 131.55‒185.16; I2 = 98%; GRADE approach evidence: high), duration of analgesia (MD = 203.92; 95% CI 169.25‒238.58; I2 = 99%; GRADE approach evidence- high), and provided higher grade quality of block (RR = 1.97; 95% CI 1.60‒2.41; I2 = 0%; GRADE approach evidence: moderate). The block positioning technique (regression coefficient: 51.45, p = 0.005) was observed as a significant predictor of the heterogeneity in the case of sensory block duration. No significant difference was observed for the risk of hypotension (RR = 2.59; 95% CI 0.63‒10.66; I2 = %). CONCLUSION: Moderate to high-quality evidence suggests dexmedetomidine is a more efficacious adjuvant to local anesthetic in BPBs than clonidine.

LC/Q-TOF MS and LC/QQQ MS based bioanalysis of a new ferrocene derivative as a potential anticancer lead with promising drug-like characteristics.

Pyrazolopyrimidine ring present in various approved drugs is reported to target the tyrosine kinase receptor. A new pyrazolopyrimidine ferrocene derivative, which targets tumor pyruvate kinase M2 showed an impressive antiproliferative profile against human oral squamous cell carcinoma cell line CAL27 assessed using Alamar blue assay. In line with the lead optimization process, the molecule was studied for physicochemical properties where a bioanalytical method has been developed in plasma on liquid chromatography-mass spectrometry and validated following the USFDA bioanalytical method validation guideline. Plasma stability and plasma protein binding potential of the molecule have been evaluated. All the major metabolites of the compound have been identified through in vitro metabolite study employing rat liver microsome, human liver microsome, and human S9 fractions. The in silico toxicity profile of the metabolites was assessed using ProTox II software. Log P, Log D, and pKa of the molecule were found to be 4.5, 5, and 12, respectively. The molecule was found to be quite stable in plasma and have a moderate affinity towards plasma proteins (about 75 % binding). Four major metabolites have been identified and characterized by UHPLCQ-TOF-MS. The metabolites were found to have a moderate safety profile. The validated bioanalytical method and the metabolic pathway will be useful for future clinical studies and to assess the safety profile of the molecule. The finding of this study may also be useful in analyzing the desired drug-like properties through bioanalysis while designing new chemical entities based on metallocenes.

Exploring Chickpea Germplasm Diversity for Broadening the Genetic Base Utilizing Genomic Resourses.

Legume crops provide significant nutrition to humans as a source of protein, omega-3 fatty acids as well as specific macro and micronutrients. Additionally, legumes improve the cropping environment by replenishing the soil nitrogen content. Chickpeas are the second most significant staple legume food crop worldwide behind dry bean which contains 17%-24% protein, 41%-51% carbohydrate, and other important essential minerals, vitamins, dietary fiber, folate, ß-carotene, anti-oxidants, micronutrients (phosphorus, calcium, magnesium, iron, and zinc) as well as linoleic and oleic unsaturated fatty acids. Despite these advantages, legumes are far behind cereals in terms of genetic improvement mainly due to far less effort, the bottlenecks of the narrow genetic base, and several biotic and abiotic factors in the scenario of changing climatic conditions. Measures are now called for beyond conventional breeding practices to strategically broadening of narrow genetic base utilizing chickpea wild relatives and improvement of cultivars through advanced breeding approaches with a focus on high yield productivity, biotic and abiotic stresses including climate resilience, and enhanced nutritional values. Desirable donors having such multiple traits have been identified using core and mini core collections from the cultivated gene pool and wild relatives of Chickpea. Several methods have been developed to address cross-species fertilization obstacles and to aid in inter-specific hybridization and introgression of the target gene sequences from wild Cicer species. Additionally, recent advances in "Omics" sciences along with high-throughput and precise phenotyping tools have made it easier to identify genes that regulate traits of interest. Next-generation sequencing technologies, whole-genome sequencing, transcriptomics, and differential genes expression profiling along with a plethora of novel techniques like single nucleotide polymorphism exploiting high-density genotyping by sequencing assays, simple sequence repeat markers, diversity array technology platform, and whole-genome re-sequencing technique led to the identification and development of QTLs and high-density trait mapping of the global chickpea germplasm. These altogether have helped in broadening the narrow genetic base of chickpeas.

Diversity and function of motile ciliated cell types within ependymal lineages of the zebrafish brain.

Motile cilia defects impair cerebrospinal fluid (CSF) flow and can cause brain and spine disorders. The development of ciliated cells, their impact on CSF flow, and their function in brain and axial morphogenesis are not fully understood. We have characterized motile ciliated cells within the zebrafish brain ventricles. We show that the ventricles undergo restructuring through development, involving a transition from mono- to multiciliated cells (MCCs) driven by gmnc. MCCs co-exist with monociliated cells and generate directional flow patterns. These ciliated cells have different developmental origins and are genetically heterogenous with respect to expression of the Foxj1 family of ciliary master regulators. Finally, we show that cilia loss from the tela choroida and choroid plexus or global perturbation of multiciliation does not affect overall brain or spine morphogenesis but results in enlarged ventricles. Our findings establish that motile ciliated cells are generated by complementary and sequential transcriptional programs to support ventricular development.

Interactive Student-Centered Neuroscience Workshops for Sixth Graders Enhance Science Knowledge and Education Attitudes.

UCNeuro, a University of California, Riverside student-run organization, developed, implemented, and tested a school-based supplemental science intervention. The purpose of this intervention was to improve students' neuroscience knowledge and education attitudes and meet, in part, California's new elementary science education standards. The intervention consisted of interactive, hands-on neuroscience workshops on the structure of a neuron, neuron-to-neuron communication, brain structure and function, autonomic nervous system function, and drug effects on the brain. Under the supervision of a faculty neuroscientist, undergraduate students implemented the intervention with 77 sixth-grade students in one school in Riverside County, California. Pre- and post-test results showed increases in students' neuroscience knowledge, confidence in achieving their goals, likeliness to go to college, and desire to attend school. Excitement about learning science material and school learning opportunities did not change after the workshops. We hope that the UCNeuro workshops can be employed and adapted to the existing curriculum to improve knowledge in the life sciences while California's new elementary science standards are being operationalized.

Mapping QTLs for 15 morpho-metric traits in Arabidopsis thaliana using Col-0 × Don-0 population.

Genome wide quantitative trait loci (QTL) mapping was conducted in Arabidopsis thaliana using F2 mapping population (Col-0 × Don-0) and SNPs markers. A total of five linkage groups were obtained with number of SNPs varying from 45 to 59 per linkage group. The composite interval mapping detected a total of 36 QTLs for 15 traits and the number of QTLs ranged from one (root length, root dry biomass, cauline leaf width, number of internodes and internode distance) to seven (for bolting days). The range of phenotypic variance explained (PVE) and logarithm of the odds ratio of these 36 QTLs was found be 0.19-38.17% and 3.0-6.26 respectively. Further, the epistatic interaction detected one main effect QTL and four epistatic QTLs. Five major QTLs viz. Qbd.nbri.4.3, Qfd.nbri.4.2, Qrdm.nbri.5.1, Qncl.nbri.2.2, Qtd.nbri.4.1 with PVE > 15.0% might be useful for fine mapping to identify genes associated with respective traits, and also for development of specialized population through marker assisted selection. The identification of additive and dominant effect QTLs and desirable alleles of each of above mentioned traits would also be important for future research.

Caspase-3 mediated programmed cell death by a gold-stabilised peptide carbene.

The synthesis of novel N-heterocyclic carbene complexes derived from a tripeptide ligand (L), containing non-natural amino acid, thiazolylalanine is described here. The peptide ligand was reacted with suitable precursors to generate gold and mercury carbene complexes. The plausible structures of both complexes were predicted by spectroscopic data and DFT calculations. The binding energy data was also analyzed to predict their stability. The gold carbene complex (1A), showed activity against MCF7 breast cancer cell line due to mitochondrial triggered caspase-3 mediated programmed cell death. Its internalization inside cells could be observed due to autofluorescence. This study affords a methodology for successful generation of peptide carbene complexes for their therapeutic potential.

Progesterone Hypersensitivity: A Challenge for Luteal Support.

Progesterone hypersensitivity is a rare phenomenon which can occur after both endogenous and exogenous exposures. We present a case of hypersensitivity to various forms and routes of exogenous progesterone. A 27-year-old female presented with primary infertility. Investigations revealed Grade 1 endometriosis and polycystic ovary syndrome. Three cycles of intrauterine insemination were attempted which were unsuccessful and in vitro fertilization was proceeded. Six blastocysts of Grade A were formed and cryopreserved. Artificial cycle was used for endometrial preparation for frozen embryo transfer (FET). However, due to failure to use exogenous progesterone due to hypersensitivity reaction, Modified Natural Cycle (MNC) was used. A follicle was formed using ovulation induction with tamoxifen and human menopausal gonadotropin. Ovulation was induced by human chorionic gonadotropin (hCG), and natural progesterone from corpus luteum was used. FET was done when endometrium was 8 mm. Pregnancy was confirmed by transvaginal ultrasound and ß-hCG levels and continued uneventfully. Endogenous progesterone can be used as an alternative for endometrial preparation for FET in patients with exogenous progesterone hypersensitivity.

Novel anti-inflammatory and analgesic agents: synthesis, molecular docking and in vivo studies.

Twelve new derivatives of benzothiazole bearing benzenesulphonamide and carboxamide were synthesised and investigated for their in vivo anti-inflammatory, analgesic and ulcerogenic activities. Molecular docking showed an excellent binding interaction of the synthesised compounds with the receptors, with 17c showing the highest binding energy (-12.50 kcal/mol). Compounds 17c and 17i inhibited carrageenan-induced rat paw oedema at 72, 76, and 80% and 64, 73, and 78% at 1 h, 2 h, and 3 h, respectively. In the analgesic activity experiment, compounds 17c, 17 g, and 17i had ED50 (µM/kg) of 96, 127, and 84 after 0.5 h; 102, 134, and 72 after 1 h and 89, 156, and 69 µM/kg after 2 h, respectively, which were comparable with 156, 72, and 70 µM/kg for celecoxib. The ulcerogenic index of the most active derivatives 17c and 17i were 0.82 and 0.89, respectively, comparable to 0.92 for celecoxib. The physicochemical studies of the new derivatives showed that they will not have oral bioavailability problems.

KDPI score is a strong predictor of future graft function: Moderate KDPI (35 - 85) and high KDPI (> 85) grafts yield similar graft function and survival
.

BACKGROUND: Efforts have been made to maximize the utility of each organ transplanted. Policy changes to capture unrealized graft years have been implemented utilizing the kidney donor profile index (KDPI). Understanding the impact of KDPI on long-term graft function is critical to an informed organ acceptance decision. METHODS: We reviewed the records of 309 consecutive deceased adult donor kidney recipients who underwent kidney transplantation at our center. We obtained KDPI of the allografts directly from United Network for Organ Sharing (UNOS) and patients were divided into four categories: KDPI ≤ 20, KDPI 21 - 35, KDPI 36 - 85, and KDPI > 85. RESULTS: Of the 309 recipients, 48 (15.5%) received kidneys from donors with KDPI ≤ 20, 57 (18.4%) from donors with KDPI 21 - 35, 161 (52.1%) from donors with KDPI 36 - 85, and 43 (13.9%) from donors with KDPI > 85. Older recipients were more likely to receive high KDPI kidneys (p = 0.025). Kaplan-Meier analysis demonstrated the KDPI > 35 group had worse survival than the KDPI ≤ 20 group, but KDPI 36 - 85 was not different from KDPI > 85. The rate of poor graft function differed at 1 year: 14.6% of KDPI ≤ 20 recipients, 14.3% of KDPI 21 - 35 recipients, 30.6% of KDPI 35 - 85 recipients, and 40.5% of KDPI > 85 recipients had serum creatinine greater than 2.0 mg/dL at 1 year. KDPI > 35 had statistically significantly greater incidence of poor graft function than KDPI ≤ 35 (p < 0.05). CONCLUSIONS: Our study demonstrates that high KDPI grafts behave more like moderate KDPI grafts (KDPI 35 - 85). Creatinine (Cr) greater than 2.0 mg/dL portends poorer long-term graft survival, and this outcome is similar amongst all recipients of KDPI > 35 allografts.

Evaluation of suspected cosmetic induced facial dermatoses with the use of Indian standard series and cosmetic series patch test.

INTRODUCTION: Awareness about skin beauty or cosmetic elegance has received worldwide attention in the present day youth oriented society. Along with careful detailed history and thorough examination patch test is considered cornerstone in diagnosis of allergic contact dermatitis. MATERIALS AND METHODS: Fifty patients suspected clinical diagnosis of contact facial dermatitis due to attended the Department of Dermatology, were included in a hospital based study. The patch test was applied on the upper back of using 32 allergens present in Indian cosmetic series and 20 known allergens in Indian standard battery series procured from Systopic Pharmaceutical Ltd, after applying the patch test, the patient was asked to come after 48h and 72h for reading the results of the patch test. RESULTS: Out of 50 patients there were 32 (64%) females (housewives 36%) patients and 18 (36%) male (farmers 12%). Itching was the most common presenting symptom in 39 patients (78%) least was hypopigmentation and pain in 2%. Forehead was the most common site of involvement in 25 patients (50%) least were cheeks in 15 patients (30%). Erythema was the commonest morphological presentation seen in 36 patients (72%). Hair dye was suspected in maximum number of patients that is 13 (26%). Most common antigen showing patch test positivity was paraphenylenediamine in nine patients (18%). There are significantly more chances of developing positive test reaction with Indian standard series compared to cosmetic series. (p=.0053 using Fischer Exact test). CONCLUSION: In India there is no legislation regarding labeling ingredients on cosmetics as in the western countries, so labelling of the contents of cosmetic products should be the main challenge in cosmetic dermatitis is to identify.

Normoglycemic diabetic nephropathy: the role of insulin resistance.

The pathophysiology of diabetic nephropathy (DN) is complex and incompletely understood. Whereas hyperglycemia is clearly important, the role of insulin resistance (IR) is increasingly recognized. We present the case of a normotensive non-smoking obese woman with nephrotic syndrome who was found to have DN by biopsy. All measures of glucose metabolism, including fasting glucose, glycosylated hemoglobin, and oral glucose tolerance testing, were repeatedly normal with little exception. IR was documented, however, based on the presence of the metabolic syndrome and an elevated homeostasis model assessment of IR. We posit that this IR is central to the pathogenesis of our patient's lesion, and this may explain other cases of DN with normoglycemia. The literature supporting this concept is discussed.

Cytodiagnosis of extramedullary plasmacytomas.

OBJECTIVE: Extramedullary plasmacytoma (EMP) constitutes approximately 4% of all plasma cell neoplasms. It may present as the sole manifestation of plasma cell neoplasm, as a solitary plasmacytoma of the bone or as a consequence of multiple myeloma. This study was done to determine the role of fine needle aspiration cytology (FNAC) in the diagnosis of EMP. STUDY DESIGN: In our study 8 cases of EMP at various sites were diagnosed on FNAC. In 3 patients EMP was the initial presentation of plasma cell neoplasm. In the remaining 5 patients the tumors occurred during the course of treatment for multiple myeloma. RESULTS: The lesions were located at various anatomic sites, including lymph node, scalp, breast, jaw, rib, clavicle and soft tissue swelling in the retrosternal region. The smears prepared from the aspirates in all cases revealed numerous plasma cells at various stages of maturation, leading to a diagnosis of EMP. Radiologic and bone marrow findings also substantiated the diagnosis of multiple myeloma in all but 1 case. CONCLUSION: FNAC offers a rapid, reliable and accurate diagnosis of EMP and thus allows initiation of appropriate treatment.

Bilateral calcified stylohyoid ligament: an incidental autopsy finding with medicolegal significance.

Eagle's syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due to pressure exerted on various structures in the head and neck region. A case report of calcified stylohyoid ligament found incidentally at autopsy and further confirmed by computed tomography scan and histopathology is herein discussed with associated medicolegal significance.
