Background: Understanding the relationship between climate change and child health is crucial for making informed decisions and implementing successful treatments. However, the extensive scientific literature on climate change and child health has not undergone a general dynamic quantitative examination. This bibliometric analysis was undertaken to study pertinent literature on climate change impact on child health over a 22-year period (2000–2022). Methods: change's A five-step PRISMA process was used to extract 1864 peer-reviewed journal articles from the Web of Science Core Collection database. The data was analysed using bibliometric software tools, including VOSviewer, CiteSpace, and Biblioshiny. Results: The annual publication patterns showed a steady increase in the number of articles published on climate change's impact on child health over the past 22 years. The most well-known climate change impact on child health monitoring articles was identified, as were the most active researchers and top-contributing nations in climate change impact on child health research. The most dependable information sources for academic researchers were further determined using the citation analysis of journals. Finally, science mapping analysis was used to visualize and study the conceptual and intellectual knowledge structures to chart the evolution of the research area related to climate change's impact on child health. Science mapping also identified emerging trends and intriguing research directions. Conclusions: This bibliometric analysis provides a comprehensive overview of the scientific landscape of climate change's impact on child health research. The findings highlight the growing interest in this field of research, as well as the key players and emerging trends. This study's results can inform future research priorities and develop effective interventions to protect children from the harmful effects of climate change.

Vitiligo is a common autoimmune pigmentary disorder characterized by destruction of functional melanocytes resulting in the appearance of depigmented patches on the skin and mucosa. These lesions pose a cosmetic challenge. The involvement of the mucosa is less, but may be the first symptom of this pathology. Depigmentation in the lips can be more easily observed and patients can be counseled regarding the condition and guided for treatment. Aims: The study describes the various clinic-epidemiological factors associated with lip vitiligo. Materials and Methods: The study sample included 100 patients of lip vitiligo of all age groups and gender. Patients with a history of herpes labialis, and history suggestive of post inflammatory depigmentation of lips secondary to various causes were excluded from this study. Also, patient vitiligo patients without lip involvement were excluded. The frequency, site, extension, association with vitiligo elsewhere, and systemic association were noted and tabulated. Results: Among 100 patients, 57 were males and 43 were females. Majority of our study subjects (63%) had onset of vitiligo between 11 and 30 years and 24% between 31 and 50 years. In the present study, 41 patients had only lip vitiligo, 55 patients had lip and vitiligo in other parts, four had involvement of lip and genital mucosa. Out of 100 patients, 71 complained that the lips were the initial lesion. The most type of vitiligo seen in our study subjects was the isolated lip vitiligo (41) and the least common was universal vitiligo (2). Leukotrichia was seen in three patients. In our study six patients had exclusive upper lip vitiligo and 40 patients had lower lip vitiligo. The remaining patients had both lower lip and upper lip involvement. Angle of the mouth was involved in 31 patients and five had marginal extension onto the skin. Of 100 patients with vitiligo nearly 19% had atleast one co-morbid condition. The most common autoimmune disease was thyroid dysfunction seen in 17% of patients. Conclusion: Though rare, lip vitiligo could be one of the earliest presentations of vitiligo and will aid in counseling the patients regarding the chronicity and thereby reduce the psychological morbidity. The data on lip vitiligo is sparse and to the best of our knowledge, there is no study on the demographic characteristics and clinical patterns of lip vitiligo.

There is an urge for traditional herbal remedies as an alternative to modern medicine in treating several ailments. Alangium salviifolium is one such plant, used traditionally to treat several diseases. In several reports, there are findings related to the use of this plant extract that demonstrate its therapeutic value. However, very few attempts have been made to identify the extensive metabolite composition of this plant. Here, we performed metabolite profiling and identification from the bark of A. salviifolium by extracting the sample in organic and aqueous solvents. The organic and aqueous extracts were fraction-collected using the Agilent 1260 Analytical Scale Fraction Collection System. Each of the fractions was analyzed on Liquid Chromatogaphy/Quadrupole Time-of-Flight LC/Q-TOF and Gas Chromatography/Quadrupole Time-of-Flight GC/instruments. The Liquid Chromatography/Mass Spectrometry (LC/MS) analyses were performed using Hydrophilic Ineraction Liquid Chromatography (HILIC), as well as reversed-phase chromatography using three separate, orthogonal reverse phase columns. Samples were analyzed using an Agilent Jet Stream (AJS) source in both positive and negative ionization modes. The compounds found were flavonoids, fatty acids, sugars, and terpenes. Eighty-one secondary metabolites were identified as having therapeutic potential. The data produced was against the METLIN database using accurate mass and/or MS/MS library matching. Compounds from Alangium that could not be identified by database or library matching were subsequently searched against the ChemSpider) database of over 30 million structures using MSMS data and Agilent MSC software.In order to identify compounds generated by GC/MS, the data were searched against the AgilentFiehn GCMS Metabolomics Library as well as the Wiley/NIST libraries.

Monolayer 2D transition metal dichalcogenides (TMDs) are known for their direct bandgaps and pronounced excitonic effects, which facilitate efficient light absorption and high photoluminescence (PL). In this study, we report a significant enhancement in PL emission from monolayers of p-type molybdenum disulfide (p-MoS 2 ), fabricated on conductive substrates-such as indium tin oxide (ITO) and gold (Au). We attribute this behaviour to the reverse injection of charge carriers from substrates to p-MoS 2 and the subsequent localization of electrons and holes in the substrate and p-MoS 2 , respectively. Such injection of charge carriers was suppressed when few-layer graphene (FLG) was used as a barrier layer. Further investigation of the PL emission characteristics from a vertically stacked hetero-bilayer (the p-n interface) of p-MoS 2 and n-MoSe 2 revealed a single resonant high-emission PL peak at 1.64 eV with the PL emission from this heterostructure significantly higher than that from free-standing monolayers. This finding contrasts sharply with the PL quenching often seen in hetero-bilayers with an n-n interface. These findings offer valuable insights into the fundamental optical and electronic properties of 2D TMDs and their heterostructures, which are essential for optimizing these materials for optoelectronic applications.

Objectives: Protein malnutrition (PMN) is a significant public health concern that can aggravate pathological states. The impact of early malnutrition on metabolism needs extensive evaluation. Current models employ short-term diet restriction and are neither ethically correct nor clinically relevant. This study aimed to develop a PMN rat model to evaluate the effects of a low-protein diet (LPD) on physiological, hematological, biochemical, and histological changes affected by malnourishment from postweaning to the 40 th week., Materials and Methods: The PMN model was developed in Wistar rats (post-weaning) by assigning animals to patented LPD (10% protein) and a control group to a normal diet (18% protein). Developed model was confirmed by biometric, biochemcial parameters and Gomez classification of malnutrition., Results: LPD-induced PMN showed stunted growth, altered biochemical (albumin range, 1.9 - 2.4 g/dL, total protein range, 5.1 - 6.4 g/dL), and hematological markers mean corpuscular volume (52.03 ± 1.34, 47.45 ± 0.44, p≤0.01), mean corpuscular hemoglobin (17.67 ± 0.47, 15.37 ± 0.18, p≤0.001) and mean corpuscular haemoglobin concentration (33.87 ± 0.22, 32.37 ± 0.24, p≤0.001) and significantly affected hepatic histology. A long-term study was conducted to analyze the pattern of developmental PMN and its stabilization over time., Conclusion: The developed PMN rat model imitates clinical conditions and is confirmed as a stable, reproducible, and reliable model for short- and long-term studies. The clinical relevance of this approach opens new avenues for research in treatment, drug development, molecular interactions, and disease model development., Competing Interests: Conflict of Interest: The authors have no conflicts of interest to declare., (Copyright© 2024 The Author.

This report describes the symptoms of pesticide poisoning in a previously healthy teenage girl. After consuming unwashed grapes for several days, the girl developed the following symptoms: drowsiness, vomiting, truncal weakness and fasciculations in the tongue and hands. Blood tests confirmed exposure to a small amount of the organophosphate (OP) compound, a type of chemical found in certain pesticides. The girl was treated with supportive care and cholinesterase reactivators, which minimised the damage caused by OP poisoning. Within 48 hours, the girl's symptoms improved and she made a full recovery. This case highlights that OP poisoning can present without classic cholinergic crisis symptoms (SLUDGING), including miosis. Fasciculations, as observed in this case, are a significant clue to the diagnosis., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Background: Since the introduction of amalgam for tooth fillings, there have been concerns that mercury toxicity could pose unacceptable health risks. Rasa shastra is an ancient medical discipline that focuses on the utilization of metals and minerals for the treatment of diseases. Nevertheless, these minerals cannot be directly administered to the human body in their natural state due to their potential adverse effects. Hence, for medicinal purposes, these metals and minerals need to undergo purification ( Shodhana ) to eliminate impurities and modify their physical, chemical, and biological characteristics., Methodology: Human gingival fibroblasts (HGF) were exposed to commercially available mercury (CA-Hg) and ayurvedically purified mercury (AP-Hg) at concentrations of 6.25 μM, 12.5 μM, 25 μM and 50 μM. The unexposed HGF cultured in basal media was considered a control. All the samples were cultured for 24 hours and 48 hours, and the cytotoxicity was analyzed by MTT assay., Results: Cell viability between the control and experimental groups varied at 24 hours, however, the results were not statistically significant (p>0.05). At 48 hours, cell viability was higher in the AP-Hg group as compared to the CA-Hg group at the concentration of 6.25 μM, and the difference was statistically significant (p<0.05). The cell proliferation assay results demonstrated a statistically significant difference in the mean optical density values (p<0.05) between CA-Hg and AP-Hg at 12.50 μM, 25 μM, and 50, μM concentrations observed at 24 hours. At 48 hours, a statistically significant difference in the mean OD values (p<0.05) between CA-Hg and AP-Hg at all four concentrations was observed. Conclusion: AP-Hg at a concentration of 6.25 μM demonstrated higher cell viability at 48 hours. Further, the cell proliferation rate was also higher for AP-Hg at all concentrations at 24 and 48 hours. These results indicated a less cytotoxic effect of AP-Hg than CA-Hg in HGF and hence could be employed for dental amalgam preparations., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Pharmacy and Bioallied Sciences.)

In our study, a series of novel 4-aminophenol benzamide-1,2,4-oxadiazole hybrid analogues have been designed and synthesized by condensing 4-hydroxyphenyl arylamides (3a-c) and 5-chloromethyl-3-aryl-1,2,4-oxadiazoles (6a-d). The structure of the synthesised compounds was verified by various spectroscopic techniques ( 1 H NMR, 13 C NMR, IR and LC-MS). All the prepared compounds were subjected to in silico and in vitro antiproliferative study against TNBC cell lines MDA-MB-468 and MDA-MB-231. The investigations revealed that compound 7k significantly promoted apoptosis against MDA-MB-468 and MDA-MB-231 cells with IC 50 values of 22.31 µM and 26.27 µM, respectively. Compound 7k interacted with crucial active sites of MAPK and exhibited the highest docking score of -7.06 kcal/mol. Docking was validated with molecular dynamic studies with simulation for 100 ns, depicting various stable interactions with MAPK. Consequently, 7k forms stable H-Bonds and π-π stacking with amino acid residues along with π-cation. Our investigations reveal that the in vitro antiproliferative study of 7k was in good correlation with the in silico studies. Hence, 7k serves as a potential novel lead for the inhibition of TNBCs by downregulating MAPK P38.Communicated by Ramaswamy H. Sarma.

Women below 40 years greatly suffer from triple negative breast cancers (TNBCs). Compared to other breast cancer cases, the poor prognosis and lower survival rate of TNBC patients make it an alarming task to save the human era from this dreadful disease. Therefore, identifying potential novel leads is urgently required to combat the TNBC. To discover a novel anticancer agent, we synthesized a series of novel 4-aminophenolbenzamide-1,3,4 oxadiazole hybrid analogues ( 7a-l). The structure of the compounds was confirmed by spectral methods (1 H & 13 C NMR, IR and MS). All the compounds were subjected to their in-silico and in-vitro antiproliferative studies against the TNBC cell lines MDA-MB-468 and MDA-MB-231. The investigations revealed that 7i has significantly promoted apoptosis against MDA-MB-468 and MDA-MB-231 cells with IC 50 values of 16.89 and 19.43 µM, respectively. Molecular docking of 7i , with MAPK has exhibited the highest binding score of -7.10 kcal/mol by interacting with crucial amino acids present at the active sites. Molecular docking is further validated with molecular dynamic studies with simulation for 100 ns, depicting various stable interactions with MAPK. Compound 7i, forms stable H-bonds and π-π stacking with amino acid residues. Molecular dynamic simulation (MDS) reveals that hydrophobic and water bridges were very prominent for 7i to bind, with the amino acid residues in close proximity to the active site of p38 MAPK. The investigations show that the In-vitro antiproliferative study of 7i agreed with the in-silico studies . Collectively, our investigations depict 7i as a potent novel lead for the inhibition of TNBCs by targeting p38 MAPK.Communicated by Ramaswamy H. Sarma.
