RESUMEN
This work examines the hydrodeoxygenation (HDO) activity of non-edible oils using a high surface area catalyst. The HDO activity was thoroughly examined and contrasted using the high surface area catalyst Ni/Pt-ZSM-5 as well as other supports like MCM-48 and H-beta. Ni/Pt bimetals supported on mesoporous ZSM-5 were created via reverse order impregnation to facilitate HDO of non-edible oils. Techniques such as XRD, FT-IR, BET, HR-TEM, HR-SEM, TPD, and TGA were used to characterize the produced catalysts. The synthesized catalysts considerably influenced the hydrodeoxygenation activities for the synthesis of lengthy chain hydrocarbons in a stainless-steel reactor with a high-pressure fixed bed between 300 and 375 °C under 10-40 bar hydrogen pressure. High levels of Ni/Pt-ZSM-5 acidity, textural, and H2 consumption qualities were discovered. Distributions of the products were also reviewed, along with comparisons of the structure-activity connections.
RESUMEN
The central dogma of molecular biology is responsible for the crucial flow of genetic information from DNA to protein through the transcription and translation process. Although the sequence of DNA is constant in all organs, the difference in protein and variation in the phenotype is mainly due to the quality and quantity of tissue-specific gene expression and methylation pattern. The term methylation has been defined and redefined by various scientists in the last fifty years. There is always huge excitement around this field because the inheritance of something is beyond its DNA sequence. Advanced gene methylation studies have redefined molecular genetics and these tools are considered de novo in alleviating challenges of animal disease and production. Recent emerging evidence has shown that the impact of DNA, RNA, and protein methylation is crucial for embryonic development, cell proliferation, cell differentiation, and phenotype production. Currently, many researchers are focusing their work on methylation to understand its significant role in expression, disease-resistant traits, productivity, and longevity. The main aim of the present review is to provide an overview of DNA, RNA, and protein methylation, current research output from different sources, methodologies, factors responsible for methylation of genes, and future prospects in animal genetics.

Advancements in the Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) along with recent developments in omics sciences have resulted in a better understanding of molecular mechanisms and pathways associated with the physio-pathological state of the animal. Metabolomics is a post-genomics tool that deals with small molecular metabolites in a given set of time which provides clear information about the status of an organism. Recently many researchers mainly focus their research on metabolomics studies due to its valuable information in the various fields of livestock management and precision dairying. The main aim of the present review is to provide an insight into the current research output from different sources and application of metabolomics in various areas of livestock including nutri-metabolomics, disease diagnosis advancements, reproductive disorders, pharmaco-metabolomics, genomics studies, and dairy production studies. The present review would be helpful in understanding the metabolomics methodologies and use of livestock metabolomics in various areas in a brief way.

Purpose: This study aimed to design a prototypic drug delivery system (DDS) made of an amphiphilic, pullulan (Pull)-derived biodegradable polymer for targeting the asialoglycoprotein receptor (ASGPR) overexpressed in HCC. Stearic acid (SA) was conjugated to increase the hydrophobicity of pullulan (Pull-SA). Methods: Pullulan (Pull) was linked to stearic acid (SA) after functional group modifications via EDC/NHS chemistry and characterized. Sorafenib tosylate (SRFT) was entrapped in pullulan-stearic acid nanoparticles (Pull-SA-SRFT) and its particle size, zeta potential, entrapment efficiency (EE), loading capacity (LC), and release efficiency was measured. The competence of Pull-SA-SRFT over SRFT in vitro was assessed using the ASGPR over-expressing PLC/PRF/5 hepatocellular carcinoma (HCC) cell line. This was done by studying cytotoxicity by MTT assay and chromosome condensation assay, early apoptosis by annexin-Pi staining, and late apoptosis by live-dead assay. The cellular uptake study was performed by incorporating coumarin-6 (C6) fluorophore in place of SRFT in Pull-SA conjugates. A biodistribution study was conducted in Swiss-albino mice to assess the biocompatibility and targeting properties of SRFT and Pull-SA-SRFT to the liver and other organs at 1, 6, 24, and 48 h. Results: The characterization studies of the copolymer confirmed the successful conjugation of Pull-SA. The self-assembled amphiphilic nanocarrier could proficiently entrap the hydrophobic drug SRFT to obtain an entrapment efficiency of 95.6% (Pull-SA-SRFT). Characterization of the synthesized nanoparticles exhibited highly desirable nanoparticle characteristics. In vitro, apoptotic studies urged that Pull-SA-SRFT nanoparticle was delivered more efficiently to HCC than SRFT. The cellular uptake study performed, gave propitious results in 4 hrs. The biodistribution study conducted in immunocompetent mice suggested that Pull-SA-SRFT was delivered more than SRFT to the liver when compared to other organs, and that the system was biocompatible. Conclusion: Pull-SA-SRFT is a promisingly safe, biodegradable, cell-specific nanocarrier and a potential candidate to target hydrophobic drugs to HCC.

Purpose: Peptide-based therapy is a promising strategy for cancer treatment because of its low drug resistance. However, the major challenge is their inability to target cancer cells specifically. So, a targeted nano-delivery system that could deliver therapeutic peptides selectively to cancer cells to stimulate their action is highly desirable. This study aims to deliver the antitumor peptide, Pep5, to breast tumor cells selectively using a targeting peptide functionalised multi-layered PLGA-PEI nanoparticles. Methods: In this study, Pep5 entrapped PLGA-PEI (Pep5-PPN) dual layered nanoparticles were developed. These nanoparticles were decorated with TKD (Pep5-TPPN) on their surface for site-specific delivery of Pep5 to breast tumor cells. The particles were then characterized using various instrumental analyses. In vitro cytotoxicity of the particles was evaluated in estrogen receptor positive (ER+ve) and triple negative breast cancer (TNBC) cells. An ex vivo tumor spheroid model was used to analyze the antitumor activity of the particles. Results: Uniformly round Pep5-TPPN particles were synthesized with an average diameter of 420.8 ± 14.72 nm. The conjugation of PEI over Pep5-PLGA nanoparticles shifted the zeta potential from -11.6 ± 2.16 mV to +20.01 ± 2.97 mV. In vitro cytotoxicity analysis proved that TKD conjugation to nanoparticles enhanced the antitumor activity of Pep5 in tested breast cancer cells. Pep5-TPPN induced cytoskeletal damage and apoptosis in the tested cells, which showed that the mechanism of action of Pep5 is conserved but potentiated. Active targeting of Pep5 suppressed the tumor growth in ex vivo spheroid models. Conclusion: A multi-layered nanoparticle functionalized with dual peptide was fabricated for active tumor targeting, which stimulated Pep5 activity to reduce the tumor growth in vitro and ex vivo.

Objective: The objective of the study is to assess the effects of adjunctive use of hyaluronic acid (HA), clinically and microbiologically in smokers and nonsmokers, in the management of chronic periodontitis. Material and Methods: 48 sites from 24 chronic periodontitis patients, including smokers and nonsmokers with probing depth >5 mm, were selected for the study. A split-mouth design was followed. Scaling and root planing (SRP) was performed for all the patients. The test sites received 0.8% HA gel whereas the control site received placebo gel. The clinical parameters plaque, gingival and bleeding indices, Pocket Probing Depth (PPD), and clinical attachment level (CAL) were evaluated at baseline, 1 and 3 months. Microbiological parameters were evaluated at baseline and 1 month. Results: The results showed reduction in PPD and gain in CAL in both smokers and nonsmokers at the end of 3rd month. The improvements in the test sites were statistically significant when compared with that of control sites. The microbiological analysis showed a significant reduction in Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis at the test sites when compared to the controls in both the groups. Conclusion: The findings in both groups suggest that the use of locally delivered 0.8% HA gel may be valuable as an adjunct to SRP in the treatment of chronic periodontitis.
RESUMEN
Purpose: The brain, protected by the cranium externally and the blood-brain barrier (BBB) internally, poses challenges in chemotherapy of aggressive brain tumors. Maximal tumor resection followed by radiation and chemotherapy is the standard treatment protocol; however, a substantial number of patients suffer from recurrence. Systemic circulation of drugs causes myelodysplasia and other side effects. To address these caveats, we report facile synthesis of a polyester-based supramolecular hydrogel as a brain biocompatible implant for in situ delivery of hydrophobic drugs. Methods: Polycaprolactone-diol (PCL) was linked to polyethyleneglycol-diacid (PEG) via an ester bond. In silico modeling indicated micelle-based aggregation of PCL-PEG co-polymer to form a supramolecular hydrogel. Brain biocompatibility was checked in Sprague Dawley rat brain cortex with MRI, motor function test, and histology. Model hydrophobic drugs carmustine and curcumin entrapment propelled glioma cells into apoptosis-based death evaluated by in vitro cytotoxicity assays and Western blot. In vivo post-surgical xenograft glioma model was developed in NOD-SCID mice and evaluated for efficacy to restrict aggressive regrowth of tumors. Results: 20% (w/v) PCL-PEG forms a soft hydrogel that can cover the uneven and large surface area of a tumor resection cavity and maintain brain density. The PCL-PEG hydrogel was biocompatible, and well-tolerated upon implantation in rat brain cortex, for a study period of 12 weeks. We report for the first time the combination of carmustine and curcumin entrapped as model hydrophobic drugs, increasing their bioavailability and yielding synergistic apoptotic effect on glioma cells. Further in vivo study indicated PCL-PEG hydrogel with a dual cargo of carmustine and curcumin restricted aggressive regrowth post-resection significantly compared with control and animals with intravenous drug treatment. Conclusion: PCL-PEG soft gel-based implant is malleable compared with rigid wafers used as implants, thus providing larger surface area contact. This stable, biocompatible, supramolecular gel without external crosslinking can find wide applications by interchanging formulation of various hydrophobic drugs to ensure and increase site-specific delivery, avoiding systemic circulation.

Hard to heal wounds such as diabetic wounds is one of the major problems in the healthcare sector. Delayed healing and shortfall of functional restoration at the wound site require upgraded wound management aids. In this study, we report that a nanofibrous mat enriched with bioactive peptides laden nano and microparticles achieve the requirements as an effective diabetic wound dressing. By means of electrospinning method, we fabricated Poly (lactic-co-glycolic acid)/Collagen nano-scale mat and surface functionalised with wound healing peptides, laden Chitosan nano and micro-sized particles, creating an Extracellular Matrix (ECM) -like structure with biomimetic features. The developed dressing displayed good cytocompatibility with Keratinocyte and fibroblast cells and enhanced their in-vitro cell proliferation and migration. Experiments in the streptozotocin-induced diabetic mice model showed that bioactive peptides released from Chitosan particles shorten the inflammatory stage and promote neovascularisation. The supporting nanoscale matrix promotes increased collagen deposition in the wound beds, thereby hastening the complete healing process by substantial tissue re-generation and functional restoration. The results evince that the nano/microparticles enriched nano-scale mat show potential as an effective wound repair dressing for diabetic wounds.
RESUMEN
We have investigated the wound healing efficiency of calcium alginate wafer embedded with growth factor entrapped PLGA nanoparticle. Herein, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) entrapped PLGA nanoparticles were synthesized and embedded in a sodium alginate gel by freeze-drying technique. The synthesized dressing exhibited a high degree of swelling and appropriate porosity. The scaffold was characterized by Scanning Electron Microscopy (SEM) showing a highly porous morphology. Also, incorporation of growth factor loaded nanoparticles in a wafer-based delivery system resulted in localized growth factor delivery at the site of the wound in a sustained manner. The biocompatibility of the scaffold was evaluated by MTT assay, which showed a higher cell proliferation in the proposed scaffold as compared to the control. In vivo wound healing efficiency of the scaffold was evaluated using a full thickness murine wound model, which showed improved re-epithelialization, collagen deposition, and angiogenesis. These results suggest the use of the scaffold as a promising wound dressing material.

CASE: We present a case of 19-year-old male patient with right sided comminuted metadiaphyseal distal femur fracture. Fixation was done using distal femur condylar locking plate. Washers were used with the screws to shimming the plate to achieve the coronal alignment and prevent stress over the screws. 2-year follow-up shows good alignment, radiological union and functional outcome without any complications. "Shimming" a locking plate with washers helps to achieve the better coronal alignment in comminuted metadiaphyseal distal femur fractures with coronal malalignment. It reduces the stress over screws and prevents implant-related complications.
RESUMEN
The variations in the protein profile of aortic-valvular (AVE) and endocardial endothelial (EE) cells are currently unknown. The current study's objective is to identify differentially expressed proteins and associated pathways in both the endothelial cells. We used endothelial cells isolated from the porcine (Sus scrofa) aortic valve and endocardium for the profiling of proteins. Label-free proteomics was performed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Our proteomics analysis revealed that 29 proteins were highly expressed, and 25 proteins were less expressed in the valve than the endocardial endothelium. The cell surface markers, such as CD63, ICAM1, PECAM1, PROCR, and TFRC, were highly expressed in EE. In contrast, CD44 was highly expressed in AVE. The pathway analysis showed that metabolic process-related proteins and extracellular matrix-related proteins were enriched in valves. Differential enrichment of signaling pathways was observed in the endocardium. The hemostasis function-related proteins were increased in both endothelial cells. The proteins and pathways enriched in aortic-valvular and endocardial endothelial cells revealed the distinct phenotype of these two closely related cells.

INTRODUCTION: Hoffa is a coronal fracture of the femoral condyle. It is an uncommon injury easily missed on X-rays, which later presents as a non-union. Computed tomography (CT) scan knee helps in diagnosing undisplaced fractures and planning the management. CASE REPORT: A 24-year-old male patient presented to us with complaints of pain, decreased range of knee movements, difficulty in walking and clicking sound at the left knee for 9 years. The patient had a history of trauma 9 years back. X-ray of the left knee showed the non-union of left lateral Hoffa fracture, which was managed with open reduction and internal fixation with CC screws using the lateral para patellar approach. At present 1.5 years follow-up, the patient is comfortable with no pain and having a complete knee range of motion. CONCLUSION: Although Hoffa fracture is rare, clinical suspicion, along with radiological investigations, is essential to diagnose Hoffa fracture. A missed diagnosis can lead to malunion or non-union, which predisposes to knee arthritis. Timely and proper management of Hoffa non-union with open reduction, stable internal fixation and early knee mobilization help in getting a better outcome.
RESUMEN
BACKGROUND: Fractures of the proximal humerus represent approximately 4% of all fractures and 26% of humerus fractures. Proper reduction, stable internal fixation and early initiation of physiotherapy help to achieve a good functional outcome. Aim of this study was to evaluate varus fixation/malunion of proximal humerus fractures and its relation to functional outcome. MATERIALS AND METHODS: We retrospectively evaluated 32 patients with proximal humerus fractures who were surgically treated between 2015 and 2017 at tertiary care hospital. We divided the patients into three groups on the basis of the neck-shaft angle as valgus group, normal group and varus group to observe the influence of neck-shaft angle on efficacy. Patients were evaluated for functional outcome using the Constant-Murley score. RESULTS: Two-part fractures had better functional outcome (Constant score = 75.15) compared to three parts with the moderate functional outcome (Constant score = 68.81) and the four-part fracture had poor functional outcome (Constant score = 52.66). After 6 months of follow-up, 13 patients had a neck-shaft angle of less than 126°. The functional outcome is significantly better among patients with normal neck-shaft angle and had a mean Constant score of 76.63 as compared to patients with varus deformity had a mean Constant score 60 (p = 0.001). 10 patients did not have medial support, in which 08 patients had neck-shaft angle less than 126° and 2 had a normal neck-shaft angle. CONCLUSION: High fracture comminution, improper restoration of medial continuity causes varus deformity of the humeral head and it leads to poor functional outcome. The small sample size is the limitation of our study.
RESUMEN
CONTEXT: The emergence of antimicrobial resistance (AMR) is a major public health crisis in India and globally. While national guidelines exist, the sources of data which form the basis of these guidelines are limited to a few well-established tertiary care centres. There is inadequate literature on AMR and antibiotic mismatch from India at community level and even less literature on AMR patterns from rural India. AIMS: The aims of this study were as follows: 1) to describe the patterns of AMR at an urban tertiary care hospital and a rural 100 bedded hospital; 2) to compare and contrast the AMR patterns noted with published ICMR guidelines; 3) to examine the issue of AMR and antibiotic mismatch; and 4) to identify local factors influencing drug-bug mismatch at the local level. SETTINGS AND DESIGN: The data were obtained from two independently conceived projects (Site 1: Urban tertiary care hospital, Site 2: Rural 100-bedded hospital). METHODS AND MATERIALS: Local antibiograms were made, and the antibiotic resistance patterns were compared between the urban and rural sites and with data published in the 2017 ICMR national guideline for AMR. STATISTICAL ANALYSIS USED: Descriptive statistics including means and medians were used. RESULTS: Our data reveal: a) a significant mismatch between sensitivity patterns and antibiotics prescribed; b) The national guidelines fail to capture the local picture of AMR, highlighting the need for local data; and c) challenges with data collection/retrieval, access and accuracy of diagnostic tools, administrative issues, and lack of local expertise limit antimicrobial stewardship efforts. CONCLUSIONS: Our study finds the burden of AMR high in both rural and urban sites, reinforcing that AMR burden cannot be ignored in rural settings. It also highlights that national data obtained from tertiary care settings fail to capture the local picture, highlighting the need for local data. Mechanisms of linking rural practices, primary health centres, and small hospitals with a common microbiology laboratory and shared data platforms will facilitate antibiotic stewardship at the community level.
RESUMEN
BACKGROUND: YouTube is now becoming important for people as a source of health related information. The aim of the present study was to assess the educational quality of YouTube videos related to Total hip replacement. METHODS: A search on YouTube for the term "Total hip replacement" was performed. Data from 47 most relevant videos were collected. Quality assessment checklists with a scale of 0-10 points were developed to evaluate the video content. Videos were grouped into poor quality (grade 0-3), acceptable quality (grade 4-7), and excellent quality (grade 8-10). RESULTS: 91% of videos were of poor educational quality (43/47), 9% were of acceptable quality (4/47) and none of the videos were of excellent quality. Common missing information was regarding non-operative treatment options and types of bearing surfaces. CONCLUSIONS: Videos regarding total hip replacement are frequently viewed on YouTube which is an unreliable educational source for patients, so it is important that surgeons should have knowledge about the available content so as to direct our patients to a suitable source. Also, surgeons should upload more informative videos that can be understood by patients which will be beneficial in providing information and education regarding Total Hip Replacement.
RESUMEN
OBJECTIVE: The aim of this study was to evaluate gingival and periodontal status in obese and non-obese type II Diabetic Patients. METHODS: The study population comprised of 75 subjects visiting the outpatient department of our institution, divided into three different groups, group 1 (obese diabetic), group 2 (non-obese diabetic), and group 3 (obese, non-diabetic). Diabetic status was assessed with HbA1c values and obesity status was assessed by body mass index (BMI) score greater than or equal to 30 kg/m2. Gingival and periodontal status were assessed using the Gingival Index (GI) and Community Periodontal Index (CPI) respectively. RESULTS: The mean gingival index score in group 1, group 2, and group 3 were 1.58, 1.54, and 1.25, respectively. Gingival status was poor among obese and non-obese diabetic subjects (Groups 1 and 2) when compared with obese non-diabetic patients (Group 3). The periodontal status showed that periodontal pockets were increased in diabetic obese group (15.4%), followed by diabetic non obese (4.66%), and non-diabetic obese (2%) group respectively and loss of attachment was severe in diabetic obese group (60.7%), followed by diabetic non obese (45.9%) and non-diabetic obese (15.3%) respectively. CONCLUSION: Gingival and periodontal status was poor in the obese diabetic group compared to non-obese diabetic and obese non diabetic group. Hence, the risk of gingivitis and periodontitis in obese diabetic patients should be addressed earlier to prevent further complications and achieve a good oral health status.
RESUMEN
Polymeric nanofibrous scaffolds provide fine-tuned structures with inter-connecting pores resembling the natural extracellular matrix (ECM) in tissues, and show good potential in assisting the creation of artificial functional tissue. Additional application of growth factors helps to regulate the cellular behaviors and tissue assembly in the scaffolds, which eases the healing process. In this study, we synthesized an electrospun polymer scaffold system enriched with nanoparticles containing growth factors for accelerated healing of diabetic wounds. BSA nanoparticles were synthesized by cross-linking with PEG aldehyde. To free the amino group of BSA, heparin was conjugated by EDC/NHS chemistry. The angiogenic growth factors bFGF and VEGF were bound to heparin by electrostatic interaction. These nanoparticles were adsorbed on to electrospun collagen/PLGA/chitosan nanofibers. The synthesized nanofiber system was evaluated in vitro for its cell viability and proliferation. In vivo experiments conducted in a streptozotocin-induced diabetic mice model showed accelerated wound healing. The excellent healing efficiency of this ECM-mimicking nanofiber scaffold makes it a great candidate for therapeutic application in diabetic wounds.
RESUMEN
Background Individuals working in the information technology (IT) industry are likely to develop lifestyle disorders. We aimed to determine the presence of defaecation-related disorders in IT personnel in Chennai. Methods This cross-sectional, questionnaire-based study was done from June to December 2018. We included employees between 18 and 60 years of age and excluded those with <1 year stay in Chennai, pregnancy and those who sent incomplete responses. The cohort was classified as normal, irritable bowel syndrome (IBS), faecal evacuation disorder (FED) and a combination of the latter two. Results The overall response rate was 95.6%. The study included 54.7% of men, and the median age was 31 years. The majority of respondents used an Indian toilet (554; 58%). Almost all (96.2%) passed stools daily, and stool consistency was soft in 59%. Based on the study criteria, 180 (18.8%) had FED, 56 (5.9%) had IBS and a small group had a combination of symptoms of IBS and FED (20; 2.1%). Respondents with symptoms of IBS had a higher proportion of comorbid states (p<0.0001), lesser stool frequency (p<0.0001) and required more toilet time (p<0.00001). Conclusion Over one-fourth (26.7%) of the respondents had defaecation-related issues, 18.8% had symptoms suggestive of FED and 5.6% that of IBS, often above 30 years of age.

Wide varieties of antibiotics are used in poultry farms to improve the growth and also to control the infection in broiler chicken. To identify the seriousness of the same in the poultry sector, current study has been designed to analyze the presence of tetracycline in poultry feed and also the tetracycline resistance among the bacteria released through the excreta of poultry. In the study, 27 bacteria belonging to the Escherichiacoli and Klebsiellapneumoniae. were isolated from the faecal samples collected from five different farms. Antibiotic susceptibility analysis showed 77% of E. coli and 100% of the K. pneumoniae. to be resistant to tetracycline. Further, molecular screening for tetA and tetB genes showed 85.18% of isolates to have tetA and 22.22% with tetB. The presence of tetracycline in collected feed samples was also analysed quantitatively by Liquid chromatography-mass spectrometry (LC-MS). Here, three out of five feed samples were found to be positive for tetracycline. The study showed a direct correlation between the antibiotic supplemented feed and the emergence of antimicrobial resistance among the intestinal microflora. The results of the study indicate the need for strict control over antibiotic use in animal feed to limit the rapid evolution and spread of antimicrobial resistance.
