Acute renal failure and hepatopathy consequent upon ingestion of cooked gallbladder of Indian carp: A case report.

Among freshwater fishes, the Indian Carp (Labeo rohita, "ROHU") is one of the most chosen species for Indian diets, but reports of toxicity are rare. This report is of a middle-aged healthy female who developed pain in the abdomen, vomiting, and diarrhea within hours of ingestion of a cooked portion of Indian carp's intestines and gallbladder. There was an inadvertent delay in diagnosis over 1 week due to the rarity of incidence and non-availability of a definite diagnostic indicator coupled with the lack of awareness and high index of suspicion. However, the patient could finally be diagnosed and treated appropriately after roving around many hospitals and then had life-threatening complications such as acute renal failure and hepatopathy, requiring repeated hemodialysis and supportive treatment before being fit for discharge. In this report, a detailed discussion of the clinical course and toxicological aspects are enumerated with a cautious note to spread awareness to facilitate prompt diagnosis.

Synthesis, crystal structure, thermal stability and biological study of bis{(2-methoxy-6-[(E)-(propylimino)methyl]phenolato}nickel(II) complex.

A Schiff base complex of nickel, bis{(2-methoxy-6-[(E)-(propylimino)methyl]phenolato}nickel(II) was synthesised by condensing bis(2-hydroxy-3-methoxybenzaldehyde) nickel (II) and n-propylamine in methanolic medium. Single crystal X-ray diffraction analysis of the complex revealed it to possess planar geometry with a monoclinic crystal system. The non-isothermal TG/DTA runs on this complex in a high purity (99.99 %) nitrogen environment at atmospheric pressure confirmed the absence of any coordinated water. A sharp endotherm in its DTA shows a melting temperature range of 168-171 °C. It is thermally stable up to 243 °C and decomposes in two steps, yielding NiO and carbon as residue. In addition to the methoxy group (-OCH3), infrared analysis (IR) confirmed the presence of the characteristic azomethine group (-C[bond, double bond]N-) which is also responsible for the biological action. It was further analysed by elemental analyser (C, H, N), 1H and 13C NMR as well as mass spectrometry. It showed considerable antibacterial activity towards Escherichia coli and Staphylococcus aureus when the concentration exceeds 200 µg/ml. The antifungal study shows significant inhibition with the antifungal drug imidazole as a positive control (PC). Small values of MIC, MBC/MIC indicate a lesser quantity of complex is required to inhibit the growth of micro-organisms.

Development of novel rapid-growing and delicious Pleurotus djamor strains through hybridization.

The development of fast-growing/short cropping period oyster mushroom (Pleurotus species) having good taste is one of the important needs of mushroom growers. Pleurotus djamor strain woody1, collected recently from the dead wood, has a short cropping period of 30 days but a moderately acceptable taste. One of the cultivated Pleurotus spp., P. djamor strain MDU1, has good taste but a long cropping period of 47 days. Thus, genetic improvement of P. djamor was carried out between these two strains by pairing monokaryons (anastomosis) to develop elite hybrid strains having a short cropping period and good taste. Monokaryons of parental strains showed variation in time required for germination; i.e., basidiospores of P. djamor strain woody1 germinated and developed monokaryotic colonies in 6 days, whereas that of P. djamor strain MDU1 developed monokaryotic colonies in 8 days of incubation. In addition, variation in the growth rate and morphology of the monokaryotic mycelia of both parental strains was noticed, and fast-growing monokaryons were selected for anastomosis. Out of 60 crosses made between mycelia of monokaryotic isolates of both parental strains, 20 crosses showed clamp connection, indicating that they were successful crosses. Out of 20 hybrids, two hybrid strains, viz., W2M4 and W4M4, exhibited higher yields than their parents. They exhibited the short cropping period trait, good taste attribute, and some specific volatile metabolites. This study showed that the developed two hybrid varieties, having desirable agronomic traits, could be used in mushroom farming to increase the mushroom grower's income.

External challenges for specialists dealing with forensic autopsies.

BACKGROUND: In addition to poor infrastructure, and human resource constraints, forensic medicine specialists in developing countries face many external challenges. OBJECTIVES: We aimed to investigate the prevalence, type, and source of external challenges confronting them including sex, age, religion, deceased's place of residence and the number of accompanying relatives. MATERIALS AND METHODS: This cross-sectional, observational study was conducted between August 2020 and July 2022 at the Mortuary of AIIMS, Bhubaneswar with the approval of the ethical committee. RESULTS: Of note, forensic medicine specialists faced external challenges in about one in five cases (20.5%). Most demands were to either minimise the autopsy procedure (n = 65) or to conduct the autopsy at inappropriate times (n = 58). The demands to minimise the autopsy procedure were significantly associated with the deceased's age (p = 0.046), religion (p = 0.010), socioeconomic class (p = 0.020) and manner of death (p = 0.019). CONCLUSIONS: Our study found that forensic medicine specialists in India face significant external challenges. Avoiding unnecessary complete autopsies, implementing night autopsies, and embracing minimally invasive autopsies are recommended to mitigate these challenges.

Knowledge, Attitude, and Practice of Patients toward Dental Implants in Need of Prosthodontic Rehabilitation.

Background: Our goal in conducting this study was to see how well-informed patients are about dental implants as a method of prosthodontic rehabilitation. Materials and Methods: "In this cross-sectional study, 500 new dental students were asked questions using a pre-made, self-administered questionnaire. A pilot study was carried out to verify the reliability of the survey instrument. Analysis of the data was performed in SPSS 16 (SPSS). We used the P 0.05 thresholds for the Student's T-test and the ANOVA to determine statistical significance." Results: In all, there were 500 people involved: 320 men and 180 women. The media and dentists were the two most common places to learn about implants, and as patients received more information, they became more informed consumers. Many people put off getting therapy because of how expensive it is. Conclusion: Only a small percentage of individuals had implants, and more than half knew nothing about them. This finding also highlighted the need of educating patients more thoroughly on this therapy option. As a result, the public has to be educated about oral health and implants in order to adopt a more favorable perspective.

Impact of educational intervention in promoting KAP of food label information to make healthier food choices among adolescents in Bangalore City.

Background: Increasing adolescent obesity, a reason for the onset of adult chronic diseases, has become an important public health priority. Food choices are impacted by the growing availability of processed and pre-packaged meals, the rise in eating out compared to eating at home, low nutrition literacy, and the inability to evaluate calorie and nutrient information. Objective: The objective is to assess the current knowledge, attitude, and practice (KAP) of the adolescents regarding food label information to make healthier food choices, to improve their KAP regarding the same through health education using pictorial representation, and to evaluate the effectiveness of the health education. Materials and Methods: An educational intervention study was performed among 200 adolescent students (13-15 years) in selected schools in Bangalore city. Health education was given using materials like charts, models, and posters in an interactive way. Pre-KAP and post-KAP were assessed using questionnaires. Results: The study comprised 145 (72.5%) girls and 55 (27.5%) boys with the mean age of 14.02 years. Only 102 (51%) were having knowledge that food labels must be read irrespective of health issues or disease. Only 81 (40.5%) calculated the total nutrient intake before taking food items before intervention, which was increased to 147 (73.5%) post intervention. Conclusion: The results of the present study successfully proved that nutritional educational intervention by pictorial representation was feasible and successfully improved the understanding and use of food label information for making healthier food choices among adolescents.

Measurements of Volatile Organic Compounds at a rural site in India: Variability and sources during the seasonal transition.

Volatile Organic Compounds (VOCs) play a vital role in tropospheric ozone formation that controls the oxidative capacity of the troposphere. A total of 31 potential ozone precursor VOCs have been measured at a tropical rural site, Gadanki (13.5°N, 79.2°E) in Southern peninsular India. This study provides the primary information about different VOCs, their chemical classification and potential sources. There is a strong seasonal and diurnal variability among the VOC composition. n-Decane and n-dodecane dominate the other VOCs and contribute to a large fraction (>50 %) of the concentration of total VOCs (TVOCs) in winter and summer, monsoon is dominated by n-dodecane and post monsoon season has been dominated by ethane emissions. The source apportionment using interspecies correlation and Positive Matrix Factorisation (PMF) analysis resulted in four potential emission source factors namely biogenic, biomass burning/biofuel, fossil fuel and natural gas emissions. Winter and summer seasons have been dominated by VOCs originating from biomass burning/biofuel factors, monsoon has been dominated by biogenic emissions and post-monsoon season has been dominated by natural gas emissions. Even though it is a rural site, there are significant finger prints of anthropogenic emissions in the form of fossil fuel and natural gas most probably due to an adjacent national highway and long range transport. However, for the overall period, the VOCs emitted from biogenic and biomass burning together dominate the other two factors, indicating the expected source factor behaviour of a rural atmosphere.

Airborne Infection Control Practices in Homes for the Aged in the Context of Tuberculosis Elimination.

BACKGROUND: National Strategic Plan to End tuberculosis (TB) in India 2020-2025 aims to prevent the emergence of TB in susceptible populations. Airborne infection control (AIC) practices in high-risk settings like homes for the aged (HFA) will be essential to achieve this. OBJECTIVE: The objective is to assess the AIC practices (AICPs) in HFA in the Kollam district in Kerala, India. MATERIALS AND METHODS: A mixed method approach was used. the study was done in five HFA s in a southern district of Kerala to find AICPs. Using purposive sampling, in-depth interviews was conducted among inmates with recent respiratory infection and administrators. Environmental measures were assessed using an observation checklist. RESULTS: Ventilation was inadequate in 25%-40% of HFA. Air change per hour and distance between beds were less. Very few inmates were aware of the need for proper ventilation and personal hygiene. Wearing masks and hand hygiene was not practiced. Administrators faced shortages of space, funds, and human resources for caring for hospitalized inmates, and psychiatric and terminally ill patients. CONCLUSIONS: There is a need to train the staff and inmates on AIC. Infrastructural improvements, like the use of partition screens in the short term and the creation of model airborne infection control HFA in the long run, with a collaborative effort from health professionals and architects, are needed for TB elimination efforts to succeed.

Steering CO2 hydrogenation toward C-C coupling to hydrocarbons using porous organic polymer/metal interfaces.

The conversion of CO2 into fuels and chemicals is an attractive option for mitigating CO2 emissions. Controlling the selectivity of this process is beneficial to produce desirable liquid fuels, but C-C coupling is a limiting step in the reaction that requires high pressures. Here, we propose a strategy to favor C-C coupling on a supported Ru/TiO2 catalyst by encapsulating it within the polymer layers of an imine-based porous organic polymer that controls its selectivity. Such polymer confinement modifies the CO2 hydrogenation behavior of the Ru surface, significantly enhancing the C2+ production turnover frequency by 10-fold. We demonstrate that the polymer layers affect the adsorption of reactants and intermediates while being stable under the demanding reaction conditions. Our findings highlight the promising opportunity of using polymer/metal interfaces for the rational engineering of active sites and as a general tool for controlling selective transformations in supported catalyst systems.

Bridging Thermal Catalysis and Electrocatalysis: Catalyzing CO2 Conversion with Carbon-Based Materials.

Understanding the differences between reactions driven by elevated temperature or electric potential remains challenging, largely due to materials incompatibilities between thermal catalytic and electrocatalytic environments. We show that Ni, N-doped carbon (NiPACN), an electrocatalyst for the reduction of CO2 to CO (CO2 R), can also selectively catalyze thermal CO2 to CO via the reverse water gas shift (RWGS) representing a direct analogy between catalytic phenomena across the two reaction environments. Advanced characterization techniques reveal that NiPACN likely facilitates RWGS on dispersed Ni sites in agreement with CO2 R active site studies. Finally, we construct a generalized reaction driving-force that includes temperature and potential and suggest that NiPACN could facilitate faster kinetics in CO2 R relative to RWGS due to lower intrinsic barriers. This report motivates further studies that quantitatively link catalytic phenomena across disparate reaction environments.

Utility of a Commercially Available Blood Steroid Profile in Endocrine Practice.

BACKGROUND: A blood steroid profile has recently become available on commercial basis in India. In this study, we report our initial experience with the use of steroid profile in the evaluation of disorders of sex development (DSD) and suspected cases of congenital adrenal hyperplasia (CAH) and discuss the potential scenarios in endocrine practice that may benefit from this steroid profile. MATERIALS AND METHODS: The study included six subjects. Patient 1 was a 46, XX girl who presented with peripubertal virilization, patient 2 was a girl who presented with normal pubertal development, secondary amenorrhea, and virilization, and patient 3 was a girl who presented with primary amenorrhea and virilization. These three patients were suspected to have CAH but had non-diagnostic serum 17 OH-progesterone levels. Patient 4 and 5 were 46, XY reared as girls who presented with primary amenorrhea alone and primary amenorrhea and virilization, respectively, and sixth subject was a heathy volunteer. All subjects were evaluated with blood steroid profile by Liquid chromatography tandem mass spectrometry (LC-MS/MS). RESULTS: Patient 1 and 2 were diagnosed to have 11 ß-hydroxylase deficiency by using the steroid profile. Patient 3 was suspected to have CAH, but the steroid profile excluded the diagnosis and helped to confirm the diagnosis as polycystic ovary syndrome. In patient 4 and patient 5, although steroid profile ruled out the possibility of steroidogenesis defects, it did not help to reach at the specific diagnosis. CONCLUSION: The blood steroid profile used in this study is most useful for the diagnosis of 11 ß-hydroxylase deficiency. The utility of this test is limited in the evaluation of 46, XY patients with under-virilization.

Formulation and evaluation of 4-benzylpiperidine drug-in-adhesive matrix type transdermal patch.

The objective of our study was to develop a transdermal patch of 4-benzylpiperidine and to evaluate its in vitro transdermal permeation profile. Appropriate pressure sensitive adhesives and additives were selected based on solubility and slide crystallization studies. Release liners and backing membranes were selected based on their ability to peel without leaving a residue and their affinity to formulation respectively. Drug-in-adhesive patches developed were investigate for their in vitro drug permeation over 48 h across dermatomed human skin using Franz diffusion cells. Silicone based pressure sensitive adhesive along with colloidal silicon dioxide as viscosity builder, fluoropolymer coated membranes as the release liner and polyester based membranes as backing were chosen to develop a drug in silicone adhesive patch. Polyisobutylene adhesive based patch was developed with drug in polyisobutylene adhesive, along with oleic acid and oleyl alcohol as permeation enhancers, polyester for the release liner and polyethylene as backing. Among the patches developed, polyisobutylene adhesive based patch with higher drug concentration exhibited superior transdermal permeation (1608.5 ±â€¯53.4 µg/cm2 over 48 h). The final patch was further tested for uniformity in coat weight, shear strength, tack and peel adhesion.

Orange Fluorescent Ru(III) Complexes Based on 4'-Aryl Substituted 2,2':6',2″-Terpyridine for OLEDs Application.

A series of ruthenium (III) complexes of the formulae [Ru(4-Mephtpy)2]Cl3(1) [Ru(L 1 )], [Ru(3,4,5-tmphtpy)2]Cl3(2) [Ru(L 2 )], and [Ru(4-thptpy)2]Cl3(3) [Ru(L 3 )], (where L = terpy = 2.2':6'2″ terpyridine ligands) are synthesized. The complexes were characterized by elemental analyses, spectroscopic and electrochemical data. The density functional theory (DFT) outlines the geometric optimisation and electronic charge transition of these complexes. Photophysical studies describe that the luminescence of Ru(III) complexes is due to electronic transition between the energy levels of singly unoccupied molecular orbitals (SUMO) and singly occupied molecular orbitals (SOMO). It also exhibits the potential charge transfer to π-π* and n-π* states due to MLCT and ILCT processes of the complexes. The observed bands centered at 591 and 620 nm demonstrate that these emissions originated from the transition of SUMO to SOMO energy levels, that is, from the radiative decay from the doublet exciton. Due to the heavy metal effect of Ru(III) ions the photophysical behaviour depends on the MLCT process. In conclusion, that the all three Ru(L 1 -L 3 ) complexes are fallen orange emission.

Isolation, partial purification, biochemical characterization and detergent compatibility of alkaline protease produced by Bacillus subtilis, Alcaligenes faecalis and Pseudomonas aeruginosa obtained from sea water samples.

In the current study, bacteria isolated from sea water samples of Murdeshwar, Karnataka, were screened for the production of alkaline protease by culturing them onto skim milk agar media. Of the isolated bacteria, Bacillus subtilis, Pseudomonas aeruginosa and Alcaligenes faecalis showed distinct zones of hydrolysis due to enzyme production. They were each inoculated into enzyme production media under submerged fermentation conditions at 37 °C for 48 h with a constant agitation of 120 rpm. Partial purification of alkaline protease was carried out by isoelectric precipitation. Enzyme activity was determined under varying conditions of pH, incubation temperature, different substrates, carbon and nitrogen sources and salt concentrations using sigma's universal protease activity assay. Enzyme immobilization was carried out using 2% Sodium alginate and 0.1 M ice cold CaCl2 and its activity under varying pH, temperature conditions and detergent compatibility was assayed. Efficacy of enzyme in stain removal was tested and haemolysis was observed within of 60 s which resulted in removal of the stain. Among the three organisms, enzyme from Bacillus subtilis showed highest activity in all cases indicating that it was the most ideal organism for enzyme production.

Epituberculosis Revisited: Case Report and Review.

Primary pulmonary tuberculosis can involve regional lymph nodes which may resolve spontaneously or on treatment; or they may enlarge causing extrinsic bronchial compression; or cause endobronchial inflammation and ulceration; or a node may erode through the bronchial wall with extrusion of caseous materials into the bronchial tree, causing focal or lobar pneumonia. This erosion is seen radiologically as hilar lymphadenopathy, with atelectasis and consolidation and described as "epituberculosis". It is more common in infants than older children. We hereby describe the case of a 13-year-old child with right hilar lymphadenopathy and right upper lobe consolidation on chest x-ray. We demonstrated by fibreoptic bronchoscopy that this epituberculosis resulted from perforation of a lymph node and discharge of caseous material into the upper lobe bronchus with resultant endobronchial obstruction. Thus a tuberculous ruptured lymph node may lead to clinical and radiological worsening, but this does not indicate development of drug resistance in these patients and they respond well to the same treatment regimen.

When Pain Is Medicine.

Stripped of any sense of comfort or dignity on that hospital bed, my 84-year-old father, my best friend, was enduring raw, intrusive medical procedures against his own wish; defenseless, vulnerable, agonized. A feeding tube went in through his nose; catheter tubes drained urine out of his bladder; a suction pump drew out fluid from his airway. A needle jammed into the central line, making it impossible for him to turn his head. Dialysis took over the job of his kidneys. But no painkillers were given for fear his weak heart could not take more chemicals. Three nights later, the blood report arrived, which stated my father had no blood infection, for which he was undergoing treatment for a week. Could they not have waited till the report came before breaking him up?

Non-Ablative Fractional Laser to Facilitate Transdermal Delivery.

The advances in laser technology have led to its rapidly expanding applications in dermatology. This study aims at the novel use of a non-ablative fractional laser to enhance transdermal permeation of diclofenac sodium and sumatriptan succinate. The effects of the laser on skin were characterized visually with dye binding, scanning electron microscopy, pore permeability index, and histology. In vitro transdermal permeation of drugs through laser treated and untreated human dermatomed skin was analyzed over 24 h and quantified by HPLC. Drug transport through untreated skin resulted in transdermal delivery of 72.61 µg/cm2 ± 50.35 and 22.80 ± 0.64 µg/cm2 of diclofenac sodium and sumatriptan succinate, respectively. Laser treatment of skin significantly increased (p < 0.005) delivery of diclofenac sodium to 575.66 ± 207.18 µg/cm2 and sumatriptan succinate to 498.32 ± 97.54 µg/cm2. This is a first of its kind study that demonstrates the use of 1410 nm non-ablative fractional laser to enhance transdermal permeation of 2 small molecular weight drugs.

Functional characterization of an AQP0 missense mutation, R33C, that causes dominant congenital lens cataract, reveals impaired cell-to-cell adhesion.

Aquaporin 0 (AQP0) performs dual functions in the lens fiber cells, as a water pore and as a cell-to-cell adhesion molecule. Mutations in AQP0 cause severe lens cataract in both humans and mice. An arginine to cysteine missense mutation at amino acid 33 (R33C) produced congenital autosomal dominant cataract in a Chinese family for five generations. We re-created this mutation in wild type human AQP0 (WT-AQP0) cDNA by site-directed mutagenesis, and cloned and expressed the mutant AQP0 (AQP0-R33C) in heterologous expression systems. Mutant AQP0-R33C showed proper trafficking and membrane localization like WT-AQP0. Functional studies conducted in Xenopus oocytes showed no significant difference (P > 0.05) in water permeability between AQP0-R33C and WT-AQP0. However, the cell-to-cell adhesion property of AQP0-R33C was significantly reduced (P < 0.001) compared to that of WT-AQP0, indicated by cell aggregation and cell-to-cell adhesion assays. Scrape-loading assay using Lucifer Yellow dye showed reduction in cell-to-cell adhesion affecting gap junction coupling (P < 0.001). The data provided suggest that this mutation might not have caused significant alterations in protein folding since there was no obstruction in protein trafficking or water permeation. Reduction in cell-to-cell adhesion and development of cataract suggest that the conserved positive charge of Extracellular Loop A may play an important role in bringing fiber cells closer. The proposed schematic models illustrate that cell-to-cell adhesion elicited by AQP0 is vital for lens transparency and homeostasis.
