The distal-proximal relationships among the human moonlighting proteins: Evolutionary hotspots and Darwinian checkpoints.

Moonlighting proteins, known for their ability to perform multiple, often unrelated functions within a single polypeptide chain, challenge the traditional "one gene, one protein, one function" paradigm. As organisms evolved, their genomes remained relatively stable in size, but the introduction of post-translational modifications and sub-strategies like protein promiscuity and intrinsic disorder enabled multifunctionality. Enzymes, in particular, exemplify this phenomenon, engaging in unrelated processes alongside their primary catalytic roles. This study employs a systematic, quantitative informatics approach to shed light on human moonlighting protein sequences. Phylogenetic analyses of human moonlighting proteins are presented, elucidating the distal-proximal relationships among these proteins based on sequence-derived quantitative features. The findings unveil the captivating world of human moonlighting proteins, urging further investigations in the emerging field of moonlighting proteomics, with the potential for significant contributions to our understanding of multifunctional proteins and their roles in diverse cellular processes and diseases.

Bio-mediated detoxification of heavy metal contaminated soil and phytotoxicity reduction using novel strain of Brevundimonas vancanneytii SMA3.

Heavy metals pose a serious environmental threat on a global scale due to their toxicity towards livings. Therefore, removing harmful metals from the environment has become more challenging in recent years. The objective of this study is to isolate, examine, and characterize naturally existing bacteria that possess the ability to mitigate and detoxify heavy metals such as cadmium, mercury, and lead. The selected bacteria SMA3 actively demonstrated metal tolerance during screening and was then employed for biosorption study using a lab-scale technique. The bacterium belonged to Brevundimonas sp., according to 16 S rRNA analysis. To enhance the removal efficiency of SMA3, response surface methodology (RSM) was employed, resulting in the identification of optimized conditions (pH 7, temperature 30 °C and shaking speed 120 rpm) for achieving maximum removal percentage (69.5 % of Cd, 58.6 % of Hg, and 85.1 % of Pb) within 72 h. The structural changes induced by microbial treatment were demonstrated by comparing the findings of FESEM images and FTIR spectra confirming the disappearance of C ^ C, C]O peaks along with C]O, C-O-C, C-H, and O-H bond destabilization following bioaccumulation. Moreover, in terms of phytotoxicity evaluation, it was observed that the treated soil, containing both heavy metals and the selected potent bacterial strain, exhibited reduced toxicity, resulting in improved germination and growth parameters for the seeds of Solanum lycopersicum (tomato plant). Overall, the selected bacterial strain demonstrated its potential for effectively removing multiple metals from the metal contaminated environment.

Characterization of Migraine in Children and Adolescents With Generalized Joint Hypermobility: A Case-Control Study.

Background and Objectives: The prevalence of generalized joint hypermobility (GJH) is 5-65% in children and adolescents. The hypothesis of this study was to see whether there is an association between headache characteristics and GJH in children and adolescents with migraine. Methods: We performed a primary retrospective case-control analysis of an established database of patients with headache aged 5-17 years. Results: We included 5435 participants. Approximately 31.6% of participants (1,719/5,435) were diagnosed with GJH (Beighton score ≥ 6). Nausea (73.1% vs 67.5%, χ2 with 1 degree of freedom = 17.0, p < 0.0001), phonophobia (87.3% vs 78.8%, χ2 with 1 degree of freedom = 18.0, p < 0.0001), and the PedMIDAS score (48.2 ± 52.5, 95% CI 45.7-50.6 vs 41.6 ± 51.2, 95% CI 40.0-43.3, effect size = 0.13, p < 0.0001) were noted to be more severe in participants with GJH than those without GJH. Discussion: Youths with GJH and migraine were noted to have more severe migraine characteristics.

Elicitation of E-waste (acrylonitrile-butadiene styrene) enriched soil bioremediation and detoxification using Priestia aryabhattai MGP1.

Given the rise in both usage and disposal of dangerous electronics, there is a catastrophic rise in assemblage of electronic waste (e-waste). E-waste including various plastic resins are among the most frequently discarded materials in electronic gadgets. In current digital era, managing e-waste has become universal concern. From the viewpoint of persisting lacuna of e-waste managing methods, the current study is designed to fabricate an eco-friendly e-waste treatment with native soil bacteria employing an enrichment culture method. In the presence of e-waste, indigenous soil microbes were stimulated to degrade e-waste. Microbial cultures were isolated using enrichment medium containing acrylonitrile-butadiene styrene (ABS) as the primary carbon source. Priestia aryabhattai MGP1 was found to be the most dominant e-polymer degrading bacterial isolate, as it was reported to degrade ABS plastic in disposed-off television casings. Furthermore, to increase degradation potential of MGP1, Response Surface Methodology (RSM) was adopted which resulted in optimized conditions (pH 7, shaking-speed 120 rpm, and temperature 30 °C), for maximum degradation (18.88%) after 2 months. The structural changes induced by microbial treatment were demonstrated by comparing the findings of Field emission scanning electron microscopy (FESEM) images and Fourier Transform Infrared (FTIR) spectra confirming the disappearance of ≡ C─H peaks along with C-H, C=C and C ≡N bond destabilization following degradation. Energy-dispersive X-ray (EDX) analyzers of the native and decomposed e-polymer samples revealed a considerable loss in elemental weight % of oxygen by 8.4% and silica by 0.5%. Magnesium, aluminium and chlorine which were previously present in the untreated sample, were also removed after treatment by the bacterial action. When seeds of Vigna radiata were screened using treated soil in the presence of both e-waste and the chosen potent bacterial strain, it was also discovered that there was reduced toxicity in terms of improved germination and growth metrics as a phytotoxicity criterion.

Trigeminal Autonomic Cephalalgias and Neuralgias in Children and Adolescents: a Narrative Review.

PURPOSE OF REVIEW: To summarize the available literature as well as the authors' experience on trigeminal autonomic cephalalgias (TACs) and cranial neuralgias in children and adolescents. RECENT FINDINGS: While TACs and cranial neuralgias are rare in children, several recent case series have been published. TACs in children share most of the clinical features of TACs in adults. However, there are many reported cases with clinical features which overlap more than one diagnosis, suggesting that TACs may be less differentiated in youth. Indomethacin-responsive cases of cluster headache and SUNCT/SUNA have been reported in children, whereas in adults indomethacin is usually reserved for paroxysmal hemicrania and hemicrania continua. Neuralgias appear to be rare in children. Clinical features are often similar to adult cases, though clinicians should maintain a high index of suspicion for underlying causes.

Molecular and cellular pathophysiology of circulating cardiomyocyte-specific cell free DNA (cfDNA): Biomarkers of heart failure and potential therapeutic targets.

Pathological cardiac damage during heart failure is associated with cell death and damage associated molecular patterns (DAMPs) release which triggers a viscous cycle of sterile inflammation to mediate maladaptive cardiac tissue remodelling during the progression to heart failure. DAMPs like cytokines, chemokines, and nuclear or mitochondrial genomic fragments are released in the pathological myocardium. Interestingly, circulating or cytosolic DNA fragments can play a role in the disease by interaction with nucleic acid sensors expressed in cardiomyocyte and non-myocyte neighbouring cells. The circulating cell free DNA (cfDNA) fragments have been clinically reported as markers for various diseases including cardiovascular pathophysiology. Such cfDNA within the DAMP pool can mediate intra- and inter-cellular signalling cascade to upregulate transcriptional expression of inflammatory mediators and trigger oxidative stress within cells. The cellular role of such genomic equivalents varying with chronic or acute stress might be correlated with the cell death forms encountered in myocardium during disease progression. Thus, cfDNA can be phenotypically correlated as a critical player towards upregulation of pathological processes like interstitial fibrosis, cardiomyocyte contractile dysfunction and cell death. Herein, we review the association of cfDNA with heart failure and analyse their potential usage as novel and effective therapeutic targets towards augmentation of cardiac function.

Safety or service? Effects of employee prosocial safety-rule-breaking on consumer satisfaction.

The COVID-19 pandemic makes restaurants implement new safety rules. However, because of consumers' and employees' resistance, employees may break these rules to improve the service experience. This paper examines how employees' prosocial safety-rule-breakings (PSRB) affect consumer satisfaction. We propose that PSRB has two competing effects on consumers' (including both requesters and bystanders) satisfaction via the mediating roles of service performance and perceived safety. We tested our proposed model in two experiments, adopting a 2 (Consumer role: Requesters vs. Bystanders) × 2 (PSRB level: Low vs. High) between-subject experimental design. Our findings suggest that PSRB has a strong negative relationship with bystanders' service performance rating. PSRB harms both requesters' and bystanders' perceived safety. PSRB reduces consumer satisfaction, and the relationship is stronger for bystanders (vs. requesters). This study demonstrates the importance for hospitality organizations to ensure safety rule compliance during and after the pandemic.

A review on biosurfactant producing bacteria for remediation of petroleum contaminated soils.

The discharge of potentially toxic petroleum hydrocarbons into the environment has been a matter of concern, as these organic pollutants accumulate in many ecosystems due to their hydrophobicity and low bioavailability. Petroleum hydrocarbons are neurotoxic and carcinogenic organic pollutants, extremely harmful to human and environmental health. Traditional treatment methods for removing hydrocarbons from polluted areas, including various mechanical and chemical strategies, are ineffective and costly. However, many indigenous microorganisms in soil and water can utilise hydrocarbon compounds as sources of carbon and energy and hence, can be employed to degrade hydrocarbon contaminants. Therefore, bioremediation using bacteria that degrade petroleum hydrocarbons is commonly viewed as an environmentally acceptable and effective method. The efficacy of bioremediation can be boosted further by using potential biosurfactant-producing microorganisms, as biosurfactants reduce surface tension, promote emulsification and micelle formation, making hydrocarbons bio-available for microbial breakdown. Further, introducing nanoparticles can improve the solubility of hydrophobic hydrocarbons as well as microbial synthesis of biosurfactants, hence establishing a favourable environment for microbial breakdown of these chemicals. The review provides insights into the role of microbes in the bioremediation of soils contaminated with petroleum hydrocarbons and emphasises the significance of biosurfactants and potential biosurfactant-producing bacteria. The review partly focusses on how nanotechnology is being employed in different critical bioremediation processes.

Orthostatic Headaches Associated With Spontaneous Intracranial Hypotension and Autonomic Dysfunction-A Case Series in Young Patients.

Background: Orthostatic headaches can be noted in spontaneous intracranial hypotension and orthostatic intolerance. We present a case series of young patients diagnosed with spontaneous intracranial hypotension and were treated for the same but subsequently developed orthostatic intolerance. Methods: We retrospectively reviewed charts for seven young patients with orthostatic headaches related to spontaneous intracranial hypotension and orthostatic intolerance. Results: Patients were diagnosed with spontaneous intracranial hypotension. Diagnosis was confirmed by identifying epidural contrast leakage and three of seven patients were noted to have early renal contrast excretion on computerized tomography myelography. Patients were treated with epidural blood patches. All patients showed persistent symptoms of autonomic dysfunction after treatment of spontaneous intracranial hypotension and orthostatic intolerance was confirmed with head-up tilt table test. Conclusions: Patients with spontaneous intracranial hypotension failing to improve following epidural blood patching should be evaluated for orthostatic intolerance.

Pediatric-onset trigeminal autonomic cephalalgias: A systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: There are five headache disorders composing the trigeminal autonomic cephalalgias (cluster headache, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA), and hemicrania continua). Little is known about these disorders in the pediatric population. The objectives of this study are to report the full age ranges of pediatric trigeminal autonomic cephalalgias and to determine if pediatric-onset trigeminal autonomic cephalalgias display similar signs and symptoms as adult onset. METHODS: Search criteria in Medline Ovid, Embase, PsycINFO, and Cochrane Library were created by a librarian. The remainder of the steps were independently performed by two neurologists using PRISMA guidelines. Inclusion criteria for titles and abstracts were articles discussing cases of trigeminal autonomic cephalalgias with age of onset 18 or younger, as well as any epidemiological report on trigeminal autonomic cephalalgias (as age of onset data was often found in the results section but not in the title or abstract). Data extracted included age of onset, sex, and International Classification of Headache Disorders criteria for trigeminal autonomic cephalalgias (including pain location, duration, frequency, autonomic features, restlessness) and some migraine criteria (photophobia, phonophobia, and nausea). Studies that did not meet full criteria for trigeminal autonomic cephalalgias were examined separately as "atypical trigeminal autonomic cephalalgias"; secondary headaches were excluded from this category. RESULTS: In all, 1788 studies were searched, 86 met inclusion criteria, and most (56) examined cluster headache. In cluster headache, onset occurred at every pediatric age (range 1-18 years) with a full range of associated features. Autonomic and restlessness features were less common in pediatric patients, while migrainous features (nausea, photophobia, and phonophobia) were found at similar rates. The sex ratio of pediatric-onset cluster headache (1.8, 79 male and 43 female) may be lower than that of adult-onset cluster headache. Data for other trigeminal autonomic cephalalgias, while more limited, displayed most of the full range of official criteria. The data for atypical trigeminal autonomic cephalalgias were also limited, but the most common deviations from the official criteria were abnormal frequencies and locations of attacks. CONCLUSIONS: Trigeminal autonomic cephalalgias can start early in life and have similar features to adult-onset trigeminal autonomic cephalalgias. Specifically, pediatric-onset cluster headache patients display the full range of each criterion for cluster headache (except maximum frequency of six instead of eight attacks per day). However, cranial autonomic features and restlessness occur at a lower rate in pediatrics. Additional information is needed for the other trigeminal autonomic cephalalgias. As for expanding the ICHD-3 criteria for pediatric-onset trigeminal autonomic cephalalgias, we have only preliminary data from atypical cases, which suggests that the frequency and location of attacks sometimes extend beyond the official criteria.Trial Registration: This study was registered as a systematic review in PROSPERO (registration number CRD42020165256).

Branched crack patterns in layers of Laponite® dried under electric fields: Evidence of power-laws and fractal scalin>.

In the present work we report crack patterns formed in aqueous Laponite® gel in a rectangular box, while exposed to a uniform static electric field. The crack pattern shows a very interesting tree-like geometry extending from the positive to the negative electrode. At the positive electrode a large number of cracks appear at first and merge with each other in stages thus forming tree-like fractal structures. These structures are reminiscent of the Bethe lattice or Cayley tree. The "trees" divide the system into peds of varying size, with numerous smaller ones on the positively charged end, gradually increasing in size, and decreasing in number towards the negative end. If the cumulative distribution of the number of peds exceeding a certain area in size, is plotted against that area, a power-law relation is obtained. This implies a scale-invariant fractal character of the pattern. For a given system size, the exponent of the power-law has a nearly constant value for different applied voltages. We present an experimental study demonstrating this behaviour and discuss how it compares with similar distributions of river-basin areas and viscous fingers in a Hele-Shaw cell.

Expanding the Phenotypic Spectrum of CACNA1H Mutations.

BACKGROUND: The CACNA1H gene mutations encoding the α1H subunit of Cav3.2 T-type calcium channels have been associated with generalized epilepsy. Focal or multifocal epilepsy and systemic (immunologic and gastrointestinal) involvement associated with these mutations have not been described previously. We detail the clinical characteristics of five patients with CACNA1H mutations and expand its phenotypic spectrum. METHODS: A case series of five patients with pathogenic CACNA1H mutations was evaluated. The pathogenicity of the mutations was predicted by polymorphism phenotyping (Polyphen-2) and sorting-intolerant-from-tolerant analysis. RESULTS: Mean age of seizure onset was 8.2 ± 3.7 years. Three patients had de novo mutations in the CACNA1H gene, and two patients inherited the mutation from an asymptomatic parent. The patients experienced different types of seizures including absence, focal seizures without awareness, focal seizures with secondary generalization, and myoclonic, atonic, and generalized tonic-clonic seizures. Electroencephalography showed focal, multifocal, or generalized discharges. One patient had autism and global developmental delay. Two patients had failure to thrive and selective antibody deficiency. CONCLUSIONS: CACNA1H mutations can be associated with susceptibility to develop generalized epilepsy and focal or multifocal epilepsy of varying severity. Phenotypic features involving other organ systems (immune, gastrointestinal) can occur in addition to epilepsy, developmental delay, and autism.

Extraction of lignin, structural characterization and bioconversion of sugarcane bagasse after ionic liquid assisted pretreatment.

The primary focus of this work was to recover lignin and investigate the structural changes in sugarcane bagasse after pretreatment with ionic liquid 1-ethyl-3-methylimidazolium acetate ([EMIM]oAc). 90% lignin recovery was achieved while bagasse was treated with [EMIM]oAc at 140 °C, 120 min reaction time and 1:20 bagasse to the ionic liquid ratio (w/w). The impact of ionic liquid pretreatment on bagasse was confirmed by qualitative analysis of untreated and pretreated bagasse. Scanning electron microscopy analysis exhibited the porous and irregular structure of bagasse after pretreatment. X-ray powder diffraction analysis verified a decrease in crystallinity as a result of the pretreatment process by showing a 14.7% reduction of Crystallinity index after ionic liquid treatment. The efficacy of [EMIM]oAc on bagasse treatment was also examined by enzymatic hydrolysis which manifested an increase in reducing sugar yield as a result of pretreatment. Maximum yield of 54.3% reducing sugar was obtained after 72 h enzymatic hydrolysis of pretreated bagasse. Recovered lignin was analyzed qualitatively. 1D NMR spectroscopy of lignin revealed the presence of essential functional groups whereas 2D NMR spectroscopy showed the dominance of etherified syringyl unit. Further ionic liquid recovery and reuse were substantiated by Gel permeation chromatography analysis of lignin. Weight average molecular weight (Mw) of lignin extracted by fresh [EMIM]oAc was obtained as 1769 g/mol (in the previous study) while lignin recovered by recycled [EMIM]oAc showed almost equal Mw 1765 g/mol in this study. Thus, the current investigation corroborated satisfactory performance of [EMIM]oAc in lignocellulose processing which further enhanced enzymatic hydrolysis in the subsequent step.

Long-Term Outcomes of Older Adults with and Without Delirium Immediately After Recovery from General Anesthesia for Surgery.

OBJECTIVE: Postoperative delirium, occurring days after surgery, is associated with both short- and long-term adverse events. Postanesthesia care unit (PACU) delirium, immediately after recovery from anesthesia, is associated with continued delirium in the succeeding days and adverse cognitive outcomes at discharge. Longer-term consequences are unclear. The objective was to evaluate 18-month outcomes of patients with versus without delirium in the PACU after surgery with general anesthesia. METHODS: In a prospective, observational, cohort study, 91 consecutive English-speaking patients, aged at least 70 years and capable of independently providing informed consent before surgery, were followed after admission for a surgical procedure in one teaching hospital. Patients completed cognitive testing before surgery. After recovery from general anesthesia, they were evaluated for a DSM-IV diagnosis of delirium. Participants or proxies were evaluated, at a median of 19 months after surgery (interquartile range: 18-20 months), for survival, cognitive and physical functioning, and healthcare utilization outcomes. RESULTS: All 91 patients or proxies (41 with delirium [45%]) were contacted at follow-up, with 7 deaths (8%) and 3 declining further participation (3%); 81 (96% of survivors) completed follow-up evaluations, demonstrating no significant cognitive or functional decline from baseline, with 75% of the cohort living independently in the community, and no differences in any outcomes between patients with versus without PACU delirium. CONCLUSION: In a small cohort of older patients evaluated 18 months after surgery, we could not detect an association of delirium diagnosed in the PACU with patient survival, cognitive/physical functioning, and healthcare utilization.
