Climate Change and Food Security in India: Challenges and Opportunities

Achieving food and nutritional security in a scenario of degrading natural resources (water, soil, biodiversity) and climate change seems to be a big challenge. Global warming has triggered the melting of glaciers, sea level rise and submergence of islands/coastal areas, and change in rainfall and temperature pattern over the next century is predicted. Such change is bound to affect water, land and biodiversity patterns which will demand a new set of land‐use patterns including enterprises, commodities, crops and varieties. Effects of climate change have already started impacting on agricultural productivity in several agroclimatic regions and subregions of India. The likely predicted scenario of climate change on agriculture, location‐specific case studies depicting climate change impacts such as drought, cold and heatwaves and required adaptation and mitigation strategies are discussed in this paper. It is emphasized that adaptations of agriculture to climate change will call upon proactive or anticipatory research on enterprises, commodities, crops, varieties and farming systems resilient to cold, heat and moisture stresses.

Human Intelectin-1 Promotes Cellular Attachment and Neutrophil Killing of Streptococcus pneumoniae in a Serotype-Dependent Manner

Human intelectin-1 (hIntL-1) is a secreted glycoprotein capable of binding exocyclic 1,2-diols within surface glycans of human pathogens such as Streptococcus pneumoniae, Vibrio cholerae, and Helicobacter pylori. For the latter, lectin binding was shown to cause bacterial agglutination and increased phagocytosis, suggesting a role for hIntL-1 in pathogen surveillance. ABSTRACT Human intelectin-1 (hIntL-1) is a secreted glycoprotein capable of binding exocyclic 1,2-diols within surface glycans of human pathogens such as Streptococcus pneumoniae, Vibrio cholerae, and Helicobacter pylori. For the latter, lectin binding was shown to cause bacterial agglutination and increased phagocytosis, suggesting a role for hIntL-1 in pathogen surveillance. In this study, we investigated the interactions between hIntL-1 and S. pneumoniae, the leading cause of bacterial pneumonia. We show that hIntL-1 also agglutinates S. pneumoniae serotype 43, which displays an exocyclic 1,2-diol moiety in its capsular polysaccharide but is unable to kill in a complement-dependent manner or to promote bacterial killing by peripheral blood mononuclear cells. In contrast, hIntL-1 not only significantly increases serotype-specific S. pneumoniae killing by neutrophils but also enhances the attachment of these bacteria to A549 lung epithelial cells. Taken together, our results suggest that hIntL-1 participates in host surveillance through microbe sequestration and enhanced targeting to neutrophils.
MYH7 variants cause complex congenital heart disease

MYH7, encoding the myosin heavy chain sarcomeric β‐myosin heavy chain, is a common cause of both hypertrophic and dilated cardiomyopathy. Additionally, families with left ventricular noncompaction cardiomyopathy (LVNC) and congenital heart disease (CHD), typically septal defects or Ebstein anomaly, have been identified to have heterozygous pathogenic variants in MHY7. One previous case of single ventricle CHD with heart failure due to a MYH7 variant has been identified. Herein, we present a single center's experience of complex CHD due to MYH7 variants. Three probands with a history of CHD, LVNC, and/or arrhythmias were identified to have MYH7 variants through multigene panel testing or exome sequencing. These three patients collectively had 12 affected family members, four with a history of Ebstein anomaly and seven with a history of LVNC. These findings suggest a wider phenotypic spectrum in MYH7‐related CHD than previously understood. Further investigation into the possible role of MYH7 in CHD and mechanism of disease is necessary to fully delineate the phenotypic spectrum of MYH7‐related cardiac disease. MYH7 should be considered for families with multiple individuals with complex CHD in the setting of a family history of LVNC or arrhythmias.
DNA methylation profiles in the blood of newborn term infants born to mothers with obesity

Maternal obesity is an important risk factor for childhood obesity and influences the prevalence of metabolic diseases in offspring. As childhood obesity is influenced by postnatal factors, it is critical to determine whether children born to women with obesity during pregnancy show alterations that are detectable at birth. Epigenetic mechanisms such as DNA methylation modifications have been proposed to mediate prenatal programming. We investigated DNA methylation signatures in male and female infants from mothers with a normal Body Mass Index (BMI 18.5–24.9 kg/m2) compared to mothers with obesity (BMI≥30 kg/m2). BMI was measured during the first prenatal visit from women recruited into the Ontario Birth Study (OBS) at Mount Sinai Hospital in Toronto, ON, Canada. DNA was extracted from neonatal dried blood spots collected from heel pricks obtained 24 hours after birth at term (total n = 40) from women with a normal BMI and women with obesity matched for parity, age, and neonatal sex. Reduced representation bisulfite sequencing was used to identify genomic loci associated with differentially methylated regions (DMRs) in CpG-dense regions most likely to influence gene regulation. DMRs were predominantly localized to intergenic regions and gene bodies, with only 9% of DMRs localized to promoter regions. Genes associated with DMRs were compared to those from a large publicly available cohort study, the Avon Longitudinal Study of Parents and Children (ALSPAC; total n = 859). Hypergeometric tests revealed a significant overlap in genes associated with DMRs in the OBS and ALSPAC cohorts. PTPRN2, a gene involved in insulin secretion, and MAD1L1, which plays a role in the cell cycle and tumor suppression, contained DMRs in males and females in both cohorts. In males, KEGG pathway analysis revealed significant overrepresentation of genes involved in endocytosis and pathways in cancer, including IGF1R, which was previously shown to respond to diet-induced metabolic stress in animal models and in lymphocytes in the context of childhood obesity. These preliminary findings are consistent with Developmental Origins of Health and Disease paradigm, which posits that adverse prenatal exposures set developmental health trajectories.
Blood Phosphorylated Tau 181 as a Biomarker for Amyloid Burden on Brain PET in Cognitively Healthy Adults.

BACKGROUND Plasma phosphorylated-tau181 (p-tau181) is a promising biomarker for Alzheimer's disease (AD) and may offer utility for predicting preclinical disease. OBJECTIVE To evaluate the prospective association between plasma p-tau181 and amyloid-β (Aβ) and tau-PET deposition in cognitively unimpaired individuals. METHODS Plasma p-tau181 levels were measured at baseline in 52 [48% women, mean 64.4 (SD 5.5) years] cognitively unimpaired Framingham Offspring cohort participants using samples stored between 2011-2014 who subsequently underwent 11C-Pittsburgh Compound-B (PiB)-PET and/or 18F-Flortaucipir (FTP)-PET scans (n = 18 with tau-PET) a mean of 6.8 (SD 0.6) years later. Our primary outcomes included Aβ-precuneus, Aβ-FLR (frontal, lateral, and retrosplenial cortices) and tau-global composite region PET deposition. Secondary outcomes included individual regional Aβ and tau PET-deposition. P-tau181 was compared with plasma neurofilament light chain (NFL) and glial fibrillary acidic protein (GFAP) in predicting PET outcomes. RESULTS P-tau181 was associated with increased Aβ deposition in the FLR (β±SE, 1.25±0.30, p < 0.0001), precuneus (1.35±0.29, p < 0.001), and other cortical regions. Plasma NFL (1.30±0.49, p = 0.01) and GFAP (1.46±0.39, p < 0.001) were also associated with FLR Aβ deposition. In models including all three biomarkers adjusted for age, sex, APOE E4 allele, AD polygenic risk score and cortical atrophy score, p-tau181 (0.93±0.31, p < 0.01, R2 = 0.18) and GFAP (0.93±0.41, p = 0.03, R2 = 0.11), but not NFL (0.25±0.51, p = 0.62, R2 = 0.01), were associated with FLR-Aβ deposition. Plasma p-tau181 was not associated with tau-PET burden. CONCLUSION In cognitively unimpaired adults, elevated plasma p-tau181 is associated with future increased Aβ deposition across multiple brain regions. Our results highlight the potential utility of p-tau181 as a blood-biomarker to screen for brain-amyloid deposition in cognitively healthy individuals in a community-setting.
Pseudo-continuous arterial spin labeling with short post-labeling delay time sensitively reflects the hemodynamics of symptomatic patients with permanent large vessel occlusion before and after revascularization

Background and Purpose This study evaluated the feasibility of arterial spin labeling (ASL) for diagnosing hemodynamic stroke due to permanent anterior circulation large vessel occlusion. Methods Three-dimensional pseudo-continuous ASL data at two post-labeling delay (PLD) times (1.5 and 2.5 s) in patients with unilateral permanent middle cerebral artery (MCA) segment 1 (M1) or internal cerebral artery (ICA) occlusion were acquired during routine magnetic resonance angiography. Sixty-one patients with symptomatic occlusion (M1, 24; ICA, 37) and 69 patients with asymptomatic occlusion (M1, 21; ICA, 48) were enrolled. Regions of interest were automatically placed in the MCA region using a template. The respective scans were compared with asymptomatic M1 or ICA occlusion scans. The ratio of signal intensity (occlusion side/non-occlusion side) in the perfusion area of MCA (asymmetry index [AI]) was compared between both groups. Results In both PLD groups, AI was significantly lower in symptomatic patients than in asymptomatic patients. The receiver operating characteristic curve showed moderate capacity for the prediction of symptomatic AI in both groups (area under the curve, 0.739 and 0.712, respectively). As a result of extracranial-intracranial bypass operation in 28 symptomatic (M1, eight; ICA, 20) patients, AI was significantly higher postoperatively in the PLD 1.5 s group than in the PLD 2.5 s group. Conclusion In symptomatic patients with permanent large vessel occlusion, the signal intensity ratio of pseudo-continuous ASL with short PLD sensitively reflects the hemodynamics before and after revascularization; therefore, this technique may be an alternative method in situations where PET or SPECT cannot be performed.
Effectiveness of vortioxetine in patients with major depressive disorder comorbid with generalized anxiety disorder: Results of the RECONNECT study

Background: Major depressive disorder (MDD) and generalized anxiety disorder (GAD) are frequently comorbid. Aims: To assess the effectiveness of vortioxetine in patients with MDD and comorbid GAD. Methods: Open-label, 8-week study (NCT04220996) in 100 adult outpatients with severe MDD and severe comorbid GAD receiving vortioxetine as first treatment for the current depressive episode or switching to vortioxetine due to inadequate response to another drug for depression. Vortioxetine starting dosage was 10 mg/day, with forced up-titration to 20 mg/day after 1 week. Response was defined as ⩾50% decrease in Montgomery–Åsberg Depression Rating Scale (MADRS) and/or Hamilton Anxiety Rating Scale (HAM-A) total score from baseline; remission defined as MADRS and/or HAM-A total score ⩽10. Results: Clinically meaningful and statistically significant improvements from baseline in symptoms of depression and anxiety, and overall functioning and health-related quality of life, were observed after 8 weeks’ vortioxetine treatment (all changes p < 0.0001 vs baseline). At week 8, rates of MADRS response and remission were 61% and 35%, respectively. Corresponding rates of HAM-A response and remission were 55% and 42%. Response on both the MADRS and HAM-A scales was achieved by 52% of patients; 31% achieved remission on both scales. Vortioxetine dose up-titration was well tolerated; no unexpected adverse events were reported. Conclusion: Vortioxetine demonstrates effectiveness in significantly reducing symptoms of both depression and anxiety in patients with severe MDD comorbid with severe GAD. Findings support increasing vortioxetine dosage to 20 mg/day early in the course of therapy, and show that this may be achieved without compromising tolerability.
A multistudy analysis reveals that evoked pain intensity representation is distributed across brain systems

Information is coded in the brain at multiple anatomical scales: locally, distributed across regions and networks, and globally. For pain, the scale of representation has not been formally tested, and quantitative comparisons of pain representations across regions and networks are lacking. In this multistudy analysis of 376 participants across 11 studies, we compared multivariate predictive models to investigate the spatial scale and location of evoked heat pain intensity representation. We compared models based on (a) a single most pain-predictive region or resting-state network; (b) pain-associated cortical–subcortical systems developed from prior literature (“multisystem models”); and (c) a model spanning the full brain. We estimated model accuracy using leave-one-study-out cross-validation (CV; 7 studies) and subsequently validated in 4 independent holdout studies. All spatial scales conveyed information about pain intensity, but distributed, multisystem models predicted pain 20% more accurately than any individual region or network and were more generalizable to multimodal pain (thermal, visceral, and mechanical) and specific to pain. Full brain models showed no predictive advantage over multisystem models. These findings show that multiple cortical and subcortical systems are needed to decode pain intensity, especially heat pain, and that representation of pain experience may not be circumscribed by any elementary region or canonical network. Finally, the learner generalization methods we employ provide a blueprint for evaluating the spatial scale of information in other domains.
Advances in Designer DNA Nanorobots Enabling Programmable Functions

The advent of DNA nanotechnology has paved the way for the development of nanoscale robotics capable of executing smart and sophisticated tasks in a programmed and automatic manner. The programmability and customizable functionality of designer DNA nanorobots interfacing with biology would offer great potential for basic and applied research in the interdisciplinary fields of chemistry, biology, and medicine. This review aims to summarize the latest progress in designer DNA nanorobotics enabling programmable functions. We first describe the state‐of‐art engineering principles and the functional modules used in the rational design of a dynamic DNA nanorobot. Subsequently, we summarize the distinct types of DNA nanorobots performing sensing tasks, sensing‐and‐actuation, or continuous actuation, highlighting the versatility of designer DNA nanorobots in accurate biosensing, targeted drug delivery, and autonomous molecular operations to promote desired cellular behavior. Finally, we discuss the challenges and opportunities in the development of functional DNA nanorobotics for biomedical applications. We envision that significant progress in DNA‐enabled nanorobotics with programmable functions will improve precision medicine in the future.
No difference in outcome or migration but greater loss of bone mineral density with the Collum Femoris Preserving stem compared with the Corail stem: a randomized controlled trial with five-year follow-up.

AIMS The aim of this study was to compare the mid-term patient-reported outcome, bone remodelling, and migration of a short stem (Collum Femoris Preserving; CFP) with a conventional uncemented stem (Corail). METHODS Of 81 patients who were initially enrolled, 71 were available at five years' follow-up. The outcomes at two years have previously been reported. The primary outcome measure was the clinical result assessed using the Oxford Hip Score (OHS). Secondary outcomes were the migration of the stem, measured using radiostereometric analysis (RSA), change of bone mineral density (BMD) around the stem, the development of radiolucent lines, and additional patient-reported outcome measures (PROMs). RESULTS There were no statistically significant differences between the groups regarding PROMs (median OHS (CFP 45 (interquartile range (IQR) 35 to 48); Corail 45 (IQR 40 to 48); p = 0.568). RSA showed stable stems in both groups, with little or no further subsidence between two and five years. Resorption of the femoral neck was evident in nine patients in the CFP group and in none of the 15 Corail stems with a collar that could be studied. Dual X-ray absorbiometry showed a significantly higher loss of BMD in the proximal Gruen zones in the CFP group (mean changes in BMD: Gruen zone 1, CFP -9.5 (95% confidence interval (CI) -14.8 to -4.2), Corail 1.0 (95% CI 3.4 to 5.4); Gruen zone 7, CFP -23.0 (95% CI -29.4 to -16.6), Corail -7.2 (95% CI -15.9 to 1.4). Two CFP stems were revised before two years' follow-up due to loosening, and one Corail stem was revised after two years due to chronic infection. CONCLUSION The CFP stem has a similar clinical outcome and subsidence pattern when compared with the Corail stem. More pronounced proximal stress-shielding was seen with the CFP stem, suggesting diaphyseal fixation, and questioning its femoral neck-sparing properties in the long term.

Structural validity and internal consistency of a hypothesized factor structure of the Fugl-Meyer Assessment of the upper extremity

ABSTRACT Background Many studies have confirmed the psychometric properties of Fugl–Meyer Assessment of the upper extremity (FMA-UE). Although several modified versions of the FMA-UE form exist, their structural validity has not been fully established. Objectives To assess the structural validity and internal consistency of the original, short, and hypothesized FMA-UE forms. Methods In this cross-sectional, multicenter, observational study, the factor structure was assessed using confirmatory factor analysis (CFA) to evaluate the adequate model of each hypothetical FMA-UE form (original, 30-item, 27-item, and 6-item forms). The internal consistency of each FMA-UE form and subscale was assessed using Cronbach’s alpha after factor structure evaluation. Results We recruited 363 patients with first-episode stroke (median age = 70.0, median days = 75.0). The results of the original form models were not estimated by CFA. Of all FMA-UE forms, the 30-item form lacked three reflex items (4-factor, 30-item model) and the 27-item form lacked three reflex and three coordination items (3-factor, 27-item, second-order model); these forms demonstrated an adequate model fitness (root mean square error of approximation = 0.056/0.059, comparative fit index = 0.995/0.996, Tucker–Lewis index = 0.995/0.995). The 6-item form demonstrated a poor model fit. All FMA-UE forms and subscales showed a high internal consistency (Cronbach’s alpha>0.91). Conclusions Both 30- and 27-item FMA-UE forms showed a good factor structure; therefore, these forms are eligible for use in clinical practice. However, future studies should define the factor structure of the 6-item form.
A novel chemical inhibitor of polar auxin transport promotes shoot regeneration by local enhancement of HD-ZIP III transcription.

De novo shoot organogenesis is a prerequisite for numerous applications in plant research and breeding but is often a limiting factor, for example, in genome editing approaches. HD-ZIP III transcription factors have been characterized as crucial regulators of shoot specification, however up-stream components controlling their activity during shoot regeneration are only partially identified. In a chemical genetic screen, we isolated ZIC2, a novel activator of HD-ZIP III activity. Using molecular, physiological and hormone transport analyses in Arabidopsis and sunflower (Helianthus annuus), we examined the molecular mechanism by which the drug promotes HD-ZIP III expression. ZIC2-dependent upregulation of HD-ZIP III transcription promotes shoot regeneration in Arabidopsis and is accompanied by the induction of shoot specifying factors WUS and RAP2.6L and a subset of cytokinin biosynthesis enzymes. ZIC2's effect on HD-ZIP III expression and regeneration is based on its ability to limit polar auxin transport. We further provide evidence that chemical modulation of auxin efflux can enhance de novo shoot formation in the regeneration recalcitrant species sunflower. Activation of HD-ZIP III transcription during shoot regeneration depends on the local distribution of auxin and chemical modulation of auxin transport can be used to overcome poor shoot organogenesis in tissue culture.
Efficacy and Safety of Acupuncture and or Moxibustion for Managing Primary Dysmenorrhea: A Systematic Review and Meta-Analysis

Acupuncture and moxibustion have been accepted as add-on options for primary dysmenorrhea (PD); however, the clinical evidence is still inadequate. We searched AMED, CENTRAL, EMBASE, PubMed, Web of Science, CBM, CNKI, VIP, Wangfang database, ANZCTR, ClinicalTrials.gov, and the WHO ICTRP, from their inception to February 2021. The pooled analysis of 13 RCTs with 675 participants for VAS showed that acupuncture and moxibustion were more effective in managing PD than the control group with the MD of −1.93 (95% CI [−2.80, −1.06] and −2.67 (95% CI [−4.96, −0.38]). With the CMSS, seven studies with 487 participants showed that these modalities were more effective than the control group with the MD of −7.58 (95% CI [−10.97, −4.19]) and −3.78 (95% CI [−6.90, −0.66]). The findings indicated that acupuncture and moxibustion could relieve pain effectively and has fewer adverse events (AEs) in managing PD.
Modulation of GPCR receptors common to gut inflammatory diseases and neuronal disorders, Alzheimer’s and Parkinson’s diseases as druggable targets through Withania somnifera bioactives: an in silico study

Abstract Microorganisms in human gastrointestinal tract have profound influence on the transformation of food into metabolites which can impact human health. Along with playing crucial roles in regulating and modulating various metabolic reactions and life processes, dysbiosis of gut microbiota also affects the permeability of gut and blood-brain barrier. This increases the chance of age-related neurological disorders’ like Alzheimer’s and Parkinson’s diseases. Withania somnifera (W. somnifera) has been proclaimed as a virtuous plant for the treatment of neurodegenerative diseases and many other problems. We have studied the bioactive components of W. somnifera for combined treatment of gut-dysbiosis led bowel diseases (Inflammatory Bowel Disease, Irritable Bowel Syndrome) and the most common neurodegenerative diseases through common potential targets. This approach can solve along with curing the neurodegenerative diseases, the factors causing these diseases would also be obstructed from entering the brain, consonantly curing Inflammatory Bowel Disease and Irritable Bowel Syndrome. Our work on GPCR receptors common to gut inflammatory diseases and neuronal disorders through Network Pharmacology, Molecular docking and Dynamic Simulation approach has shown that modulation of these receptors with bioactive compounds present in W. somnifera can result in effective control of these diseases. We have found five proteins (HTR1A, HTR1B, HTR2A, HTR2B & HTR7) and five best lead compounds (Withanolide A, B, E, Q & Anahygrine) against these targets after molecular docking analysis. Our simulation studies have finally shown that amongst these five HTR1A and HTR7 proteins are the best targets with the leads Withanolide E and Withanolide A against them, respectively.
