State-of-the-Art Management of Colorectal Cancer: Treatment Advances and Innovation.

Colorectal cancer (CRC) remains a significant global health challenge, ranking among the leading causes of cancer-related morbidity and mortality worldwide. Recent advancements in molecular characterization have revolutionized our understanding of the heterogeneity within colorectal tumors, particularly in the context of tumor sidedness. Tumor sidedness, referring to the location of the primary tumor in either the right or left colon, has emerged as a critical factor influencing prognosis and treatment responses in metastatic CRC. Molecular underpinnings of CRC, the impact of tumor sidedness, and how this knowledge guides therapeutic decisions in the era of precision medicine have led to improved outcomes and better quality of life in patients. The emergence of circulating tumor DNA as a prognostic and predictive tool in CRC heralds promising advancements in the diagnosis and monitoring of the disease. This innovation facilitates better patient selection for exploration of additional treatment options. As the field progresses, with investigational agents demonstrating potential as future treatments for refractory metastatic CRC, new avenues for enhancing outcomes in this challenging disease are emerging.

Some of these compounds exhibit anti-oxidant activities. GC-MS analysis of methanol fraction exhibited the presence of following compounds: Undecane (8.52%), 2,3-Trimethylene-4-pyrone (1.79%), cis-Sinapyl alcohol (2.33%) and Umckalin (1.19%). The acetone and methanol fractions exhibited higher percentage of inhibition in DPPH assay. The overall results of this study indicate that the acetone and methanol fractions have been demonstrated to be efficacious against various diseases.

Unleashing the room temperature boronization: Blooming of Ni-ZIF nanobuds for efficient photo/electro catalysis of water.

Water splitting provides an environmental-friendly and sustainable approach for generating hydrogen fuel. The inherent energetic barrier in two-core half reactions such as the Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER) leads to undesired increased overpotential and constrained reaction kinetics. These challenges pose significant challenges that demand innovative solutions to overcome. One of the efficient ways to address this issue is tailoring the morphology and crystal structure of metal-organic frameworks (MOF). Nickel Zeolite Imidazolate Framework (Ni-ZIF) is a popular MOF and it can be tailored using facile chemical methods to unleash a remarkable bifunctional electro/photo catalyst. This innovative solution holds the capability to address prevailing obstacles such as inadequate electrical conductivity and limited access to active metal centers due to the influence of organic ligands. Thereby, applying boronization to the Ni-ZIF under different duration, one can induce blooming of nanobuds under room temperature and modify oxygen vacancies in order to achieve higher reaction kinetics in electro/photo catalysis. It can be evidenced by the 24-h boronized Ni-ZIF (BNZ), exhibiting lower overpotentials as electrocatalyst (OER-396 mV & HER-174 mV @ 20 mA/cm2) in 1 M KOH electrolyte and augmented gas evolution rates when employed as a photocatalyst (Hydrogen-14.37 µmol g-1min-1 & Oxygen-7.40 µmol g-1min-1). The 24-h boronization is identified as the optimum stage of crystalline to amorphous transformation which provided crystalline/amorphous boundaries as portrayed by X-Ray diffraction (XRD) and High Resolution-Transmission Electron Microscopy (HR-TEM) analysis. The flower-like transformation of 24-BNZ, characterized by crystalline-amorphous boundaries initiates with partial disruption of Ni-N bonds and formation of Ni-B bonds as evident from X-ray Photoelectron Spectroscopy (XPS). Further, the 24-h BNZ exhibit bifunctional catalytic activities with pre-longed stability. Overall, this work presents a comprehensive study of the electrocatalytic and photocatalytic water splitting properties of the tailored Ni-ZIF material.

Determinants of Malnutrition among Elderly Women Living in Institutional Care.

Background: Healthy aging and well-being are largely influenced by nutrition. Objective: The objective of the study was to evaluate the risk of malnutrition in elderly women residing in institutional care and its contributing factors. Methodology: One hundred institutionalized women aged 60 years and above were screened for malnutrition using Mini Nutritional Assessment (MNA) tool. Details on sociodemographic profile, physical activity, medical conditions, and food habits were gathered through researcher administered survey method. Results: The study participants had an average height of 149.70 cm (±7.31), weight of 50.72 kg (±9.11), body mass index of 22.77 kg/m2 (±4.68), body fat percentage of 31.30% (±8.99), mid-arm circumference of 27.36 cm (±7.84), calf circumference of 30.11 cm (±7.51), MNA score of 10.42 (±4.06), and hand grip strength score of 18.69 kg/lbs (±3.80). Upon analyzing the MNA scores, it was found that 9% of elderly women were well nourished, 62% were at risk of malnutrition, and 29% were malnourished. A significant difference was observed in the mean MNA scores (P < 0.05). Age, education level, body fat percentage, appetite, and dental problems were significantly associated with malnutrition (P < 0.05). Conclusion: Geriatric residents in old-age homes require adequate nutrition to maintain health. This can be achieved by providing individualized meal planning, reducing barriers to eating, and incorporating nutrient-dense foods.

Paternal stress alters synaptic density and expression of GAP-43, GRIN1, M1 and SYP genes in the hippocampus and cortex of offspring of stress-induced male rats.

Adverse experiences during pregnancy have a negative impact on the neuronal structure and behavior of offspring, but the effects of a father's life events on the outcome of progeny are scarce. The present study is intended to investigate whether paternal stress affects the offspring brain structure, especially those regions concerned with learning and formation of memory, namely the hippocampus (HC) and prefrontal cortex (PFC), and also the expression of certain genes linked to learning and memory in the offspring. Induced stress to male rats by five stressors, one per day followed by allowing them to mate with the normal, unstressed female. Synaptophysin immunoreactivity was assessed in the tissue sections of the HC and PFC as well as expression of genes concerned with learning and memory was evaluated by RT-PCR in the progeny of stress-received males. The progeny of stressed rats had reduced antisynaptophysin immunoreactivity in the HC and PFC. The synaptic density in HC was less in the A-S (Offspring of male rats who received stress during adulthood) and PA-S (offspring of male rats who received stress during both adolescence and adulthood) than in P-S (offspring of male rats who received stress during adolescence) and C-C (offspring of control) groups. Similar results were observed even in the PFC. The results of post hoc tests proved that the HC and PFC of the progeny of stress-exposed rats exhibited considerably less synaptic density than control (P<0.05), and the levels of expression of GAP-43, GRIN1, M1, and SYP genes in HC and PFC were down-regulated. This study concludes that paternal adverse experiences can affect the offspring's synaptic plasticity and also the genes, which can regulate learning and formation of memory.

A dynamic in vitro oral mastication system to study the oral processing behavior of soft foods.

A bolus-oriented artificial oral mastication system was developed to simulate the dynamics of food mastication in the human mouth. The system consists of a chewing unit, a bolus forming unit, and provisions for the dynamic incorporation of saliva during mastication. The system performance was validated with in vivo trials (n = 25) considering time-dependent changes in particle size, textural attributes and rheological behavior of the bolus. Idli, a fermented and steamed black gram-rice-based Indian food was considered the model soft food for all trials measured in triplicates. The mastication dynamics were evaluated by analyzing bolus properties during every 3 s of mastication. Large strain shear rheology tests revealed that the viscosity of the sample decreased over time. Results of in vivo trials follow close trends in particle size and rheological behavior and have no significant change in correlation with in vitro mastication results. Similar observations were made in the half softening time of idli during mastication as determined using the relative change in hardness (hardness ratio (Ht/H0)) values fitted to the Weibull model. Also, a model to simulate the time-dependent changes in bolus adhesiveness was developed.

Determining the glycaemic responses of foods: conventional and emerging approaches.

A low-glycaemic diet is crucial for those with diabetes and cardiovascular diseases. Information on the glycaemic index (GI) of different ingredients can help in designing novel food products for such target groups. This is because of the intricate dependency of material source, composition, food structure and processing conditions, among other factors, on the glycaemic responses. Different approaches have been used to predict the GI of foods, and certain discrepancies exist because of factors such as inter-individual variation among human subjects. Besides other aspects, it is important to understand the mechanism of food digestion because an approach to predict GI must essentially mimic the complex processes in the human gastrointestinal tract. The focus of this work is to review the advances in various approaches for predicting the glycaemic responses to foods. This has been carried out by detailing conventional approaches, their merits and limitations, and the need to focus on emerging approaches. Given that no single approach can be generalised to all applications, the review emphasises the scope of deriving insights for improvements in methodologies. Reviewing the conventional and emerging approaches for the determination of GI in foods, this detailed work is intended to serve as a state-of-the-art resource for nutritionists who work on developing low-GI foods.

Multifunctional applications of natural polysaccharide starch and cellulose: An update on recent advances.

The emergence of clinical complications and therapeutic challenges for treating various diseases necessitate the discovery of novel restorative functional materials. Polymer-based drug delivery systems have been extensively reported in the last two decades. Recently, there has been an increasing interest in the progression of natural biopolymers based controlled therapeutic strategies, especially in drug delivery and tissue engineering applications. However, the solubility and functionalisation due to their complex network structure and intramolecular bonding seem challenging. This review explores the current advancement and prospects of the most promising natural polymers such as cellulose, starch and their derivatives-based drug delivery vehicles like hydrogels, films and composites, in combating major ailments such as bone infections, microbial infections, and cancers. In addition, selective drug targeting using metal-drug (MD) and MD-based polymeric missiles have been exciting but challenging for its application in cancer therapeutics. Owing to high biocompatibility of starch and cellulose, these materials have been extensively evaluated in biomedical and pharmaceutical applications. This review presents a detailed impression of the current trends for the construction of biopolymer-based tissue engineering, drug/gene/protein delivery vehicles.

Prediction of in-vitro glycemic responses of biscuits in an engineered small intestine system.

The Glycemic Index (GI) indicates the effect of a food product on the increase/decrease in postprandial blood glucose levels. Monitoring the glycemic response is important, as it is associated with the human nutrition absorption. However, human or animal blood sampling involves financial, ethical, and other challenges. Accordingly, in the recent past, many human digestion models have been developed to understand the intricate changes that occur during human digestion and absorption processes. Dynamic models help in studying the digestion mechanics and hypotheses related to the health effects of food ingredients in controlled conditions. The objective of this study is to predict the GI of different biscuit composition using an engineered small intestine system, considering a mass transfer approach and in-silico simulation. Different GI was predicted for biscuits: 62 for plain biscuits (N) containing only refined wheat flour; 57 for finger millet flour biscuits (F); 51 for wheat bran fortified biscuits (W). The results were close to human in-vivo values; GI of 76 for plain biscuits (N); 58 for finger millet biscuits (F) and 41 for wheat bran fortified (W) biscuits, respectively (with no significant difference in the GI values of Engineered model and human glucose blood sampling results) which was confirmed with Bland-Altmann statistics. This finding will help in predicting the glycemic response of new biscuit products serving as an alternative approach to human blood sampling for GI analysis.

Evaluation of prolotherapy in comparison with occlusal splints in treating internal derangement of the temporomandibular joint - A randomized controlled trial.

PURPOSE: The aim of this study was to compare the efficacy of dextrose prolotherapy with that of occlusal splints in treating internal derangement of the temporomandibular joint. PATIENTS AND METHODS: A total of 34 patients with temporomandibular joint internal derangement classed as Wilkes stages II or III were recruited for the study, and were randomly divided into study and control groups with 17 patients each. The patients in these control and study groups were treated with splints and prolotherapy, respectively. Outcome parameters, such as pain, mouth opening, clicking and deviation, were assessed using the Helkimo clinical dysfunction index for a review period of 1 year. RESULTS: Nine patients in the study group had complete absence of pain, compared with only one patient in the control group. The results showed that patients who received prolotherapy demonstrated improvement in pain (p < 0.001), mouth opening (p = 0.032), and clicking (p < 0.001), but no significant difference in deviation was observed between the groups after 1 year (p = 0.862). CONCLUSION: Prolotherapy was found to be superior in providing long-term clinical relief, with reduction in pain and clicking along with improved mouth opening.

Association of G84A and C276T polymorphism in neuronal nitric oxide synthase (nNOS) gene with herpes simplex encephalitis in eastern Indian population.

In this study, a hypothesis that genetic variations in neuronal nitric oxide synthase (nNOS) could influence the susceptibility and outcome of herpes simplex encephalitis was investigated. Polymorphic loci of nNOS gene, G84A and C276T were genotyped in 132 HSE cases (Age 8.2 ± 1.3yr) and 143 in healthy individuals (Age-9.2 ± 1.6yr) of the same ethnic background from Odisha. A significantly increased risk for HSVE was associated with the AG genotype (OR = 1.73, 95%CI = 1.03-2.9, P = 0.03) and AA genotype (OR = 2.96, 95%CI = 1.04-8.4, P = 0.04) of nNOS 84G →A locus. In case of nNOS 276C→T variation, HSVE risk was linked to CT genotype (OR = 1.79, 95%CI = 1.07-3.0, P = 0.03) and TT genotype (OR = 3.6, 95%CI = 1.2-10.8, P = 0.02). Patients with poor outcome either had homo or heterozygous genotype for both SNPs, but separate genotype analysis could not show significance. But combined genotype analysis of both SNPs confirmed that GG + CC was a risk factor for development of poor outcome. (OR = 6.3, CI-1.9-20.7, P = 0.0033). Haplotype analysis of both SNP did show that "at" haplotype was significantly higher and associated with HSVE cases (OR = 2.322,CI: 1.43-3.77, P = 0.00070). The result observed in this study suggested that variation at these loci of nNOS may have decreased its expression and caused low production of NO, which have resulted in risk of HSVE but provided good outcome in these patients.

SUBJECTS AND METHODS: Unstimulated whole saliva sample was collected from 10 autistic and 10 healthy children in mixed dentition age group. Diluted saliva sample was then subjected to inductively coupled plasma emission spectroscopy for the estimation of salivary zinc concentration. STATISTICAL ANALYSIS USED: Mann-Whitney U-test. RESULTS: In children with autism salivary zinc concentration showed a linear equation when compared to healthy children. CONCLUSIONS: The low salivary zinc concentration in autistic children can reveal the pathogenesis of autism.

Impact of single centre kidney paired donation transplantation to increase donor pool in India: a cohort study.

In a living donor kidney transplantation (LDKT) dominated transplant programme, kidney paired donation (KPD) may be a cost-effective and valid alternative strategy to increase LDKT in countries with limited resources where deceased donation kidney transplantation (DDKT) is in the initial stages. Here, we report our experience of 300 single-centre KPD transplantations to increase LDKT in India. Between January 2000 and July 2016, 3616 LDKT and 561 DDKT were performed at our transplantation centre, 300 (8.3%) using KPD. The reasons for joining KPD among transplanted patients were ABO incompatibility (n = 222), positive cross-match (n = 59) and better matching (n = 19). A total of 124 two-way (n = 248), 14 three-way (n = 42), one four-way (n = 4) and one six-way exchange (n = 6) yielded 300 KPD transplants. Death-censored graft and patient survival were 96% (n = 288) and 83.3% (n = 250), respectively. The mean serum creatinine was 1.3 mg/dl at a follow-up of 3 ± 3 years. We credit the success of our KPD programme to maintaining a registry of incompatible pairs, counselling on KPD, a high-volume LDKT programme and teamwork. KPD is legal, cost effective and rapidly growing for facilitating LDKT with incompatible donors. This study provides large-scale evidence for the expansion of single-centre LDKT via KPD when national programmes do not exist.

Electrosprayed Montelukast/poly (lactic-co-glycolic acid) particle based coating: A new therapeutic approach towards the prevention of in-stent restenosis.

UNLABELLED: Drug-eluting stents (DESs), have shown promising results in prevention of in-stent restenosis after percutaneous coronary intervention (PCI). The elevated level of leukotrienes (LTs) detected in injured arteries after PCI, together with the potential role of LTs in inflammatory cascades and structural alterations in arterial wall provides the rationale for development of therapeutic strategies for prevention of in-stent restenosis using LTs receptor antagonists. Montelukast (MK) is a selective cysLT1 receptor antagonist, with anti-inflammatory and anti-proliferative properties, which has been used for treatment of various diseases. Here, we report on the fabrication of MK/PLGA particles by electrospraying, aiming towards the development of particle based coating of DESs. The electrosprayed particles incorporated with 3% and 6% w/w MK exhibited fairly spherical shape with smooth surfaces and narrow size distribution. Sustained release of MK for up to 40days was obtained for both formulations, with higher initial burst release and drug release rate for the particles with higher drug loading. The LTD4 induced proliferation and migration of human coronary artery smooth muscle cells (HCASMCs) by 35% and 85%, respectively, which was substantially antagonized using MK incorporated particles. Nevertheless, MK antagonism preserved the normal proliferation and migration of human coronary artery endothelial cells (HCAECs). Moreover, MK antagonism inhibited the LTD4 induced phenotypic transition of HCASMCs from contractile to synthetic type. The electrosprayed MK-PLGA particles can be employed as a coating for DESs to inhibit the formation of neointimal hyperplasia responsible for in-stent restenosis, yet preserve the healing rate of the stented vessel. STATEMENT OF SIGNIFICANT: Montelukast (MK) is a selective cysLT1 receptor antagonist, with anti-inflammatory and anti-proliferative properties. The LTD4 induced proliferation and migration of human coronary artery smooth muscle cells by 35% and 85%, respectively, which was substantially antagonized using MK incorporated particles. MK antagonism preserved the normal proliferation and migration of human coronary artery endothelial cells. The MK antagonism inhibited the phenotypic transition of human coronary artery smooth muscle cells from contractile to synthetic one induced by LTD4. The electrosprayed MK-PLGA particles can be employed as coating for DESs to inhibit formation of neointimal hyperplasia, responsible for in-stent restenosis.

Development of albumin-based nanoparticles for the delivery of abacavir.

The study was designed to prepare and evaluate albumin nanoparticles containing antiviral drug abacavir sulphate. Various batches of albumin nanoparticles containing abacavir sulphate were prepared by desolvation method. The abacavir loaded particles were characterized for their yield, percentage of drug loading, surface morphology, particle size, surface charge, pattern of in vitro drug release and release mechanism studies. Drug loading ranged from 1.2 to 5.9%w/w. The mean particle size and the surface charge were 418.2nm and -40.8mV respectively. The in vitro drug release varied between 38.73 and 51.36%w/w for 24h. The n value for Korsmeyer-Peppas was 0.425 indicating Fickian type drug release. The preliminary findings indicated that albumin nanoparticles of abacavir can be prepared by desolvation method with good yield, high drug loading and sustained release.

Albumin nanoparticles for the delivery of gabapentin: preparation, characterization and pharmacodynamic studies.

The study was aimed to prepare and evaluate gabapentin loaded albumin nanoparticles and to find out their effectiveness in treating epilepsy. Albumin nanoparticles of gabapentin were prepared by pH-coacervation method. The drug was administered into animals as free drug, gabapentin bound with nanoparticles, and gabapentin bound with nanoparticles coated with polysorbate 80. The polysorbate 80 coated nanoparticles increased the gabapentin concentration in the brain about 3 fold in comparison with the free drug. Moreover, the polysorbate 80 coated nanoparticles significantly reduced the duration of all phases of convulsion in both maximal electroshock induced and pentylenetetrazole induced convulsion models in comparison with free drug and drug bound with nanoparticle formulations, which indicates the ability of polysorbate 80 coated nanoparticles to enhance the gabapentin concentration in the brain.

Increasing access to renal transplantation in India through our single-center kidney paired donation program: a model for the developing world to prevent commercial transplantation.

Because access to transplantation with HLA-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end-stage renal disease (ESRD) patient in India. We present a government and institutional ethical review board approved study of 56 ESRD patients [25 two-way and 2 three-way pairs] who consented to participate in KPD transplantation at our center in 2013, performed to avoid blood group incompatibility (n = 52) or positive cross-match (n = 4). All patients had anatomic, functional, and immunologically comparable donors. The waiting time in KPD was short as compared to deceased donor transplantation. Laparoscopic donor nephrectomy was performed in 54 donors. Donor relationships were spousal (n = 40), parental (n = 13), others (n = 3), with median HLA match of 1. Graft survival was 97.5%. Three patients died with functioning graft. 16% had biopsy-proven acute rejection. Mean serum creatinine was 1.2 mg/dl at 0.73 ± 0.32 months follow-up. KPD is a viable, legal, and rapidly growing modality for facilitating LDRT for patients who are incompatible with their healthy, willing living donor. To our knowledge, this is the largest single-center report from India.

Sustained release enteric coated tablets of pantoprazole: formulation, in vitro and in vivo evaluation.

In this study, an attempt was made to deliver pantoprazole in a sustained manner using delayed release tablets. The tablets were prepared by the wet granulation method using HPMC, cassava starch and polyvinyl pyrrolidine as polymers, Avicel PH 102 (MCC) as filler and potato starch as binder. The prepared tablets were evaluated for hardness, mass variation, friability and drug content uniformity, and the results were found to comply with official standards. The prepared tablets were coated using an enteric coating polymer such as cellulose acetate phthalate, Eudragit L100 and drug coat L100 by the dip coating method. The in vitro release was studied using pH 1.2 acidic buffer and pH 6.8 phosphate buffer and the study revealed that the prepared tablets were able to sustain drug release into the intestine. The anti-ulcer activity was evaluated by a water immersion stress induced ulcer model. The enteric coated pantoprazole tablets significantly reduced ulcer formation.

Synthesis of anisotropic silver nanoparticles using novel strain, Bacillus flexus and its biomedical application.

Synthesis of metallic nanoparticles has attracted by bacterial based production and alternative to physical and chemical approaches. The present work was focused to nominate a bacterial strain for synthesis of potential silver nanoparticles. The target was achieved by screening of 127 isolates from silver mining wastes. A strain designated S-27 found to be a potential candidate for rapid synthesis of silver nanoparticles among tested microorganisms. It was subjected to molecular characterization by 16S rDNA sequence analysis. It was found that S-27 belonging to Bacillus flexus. Synthesis of silver nanoparticles was achieved by addition of culture supernatants with aqueous silver nitrate solution, immediately it turns to brown colour solution showed a peak at 420 nm corresponding to the plasmon absorbance of silver nanoparticles by UV-vis spectroscopy. Various instrumentation techniques, such as AFM, FESEM, XRD and FTIR, were adopted to characterize the synthesized nanoparticles. Anisotropic nanoparticles, such as spherical and triangular shaped nanoparticles, have been synthesized and sizes were found to be 12 and 65 nm, respectively. It was stable in aqueous solution in five months period of storage at room temperature in the dark. Synthesized nanoparticles showed efficacy on antibacterial property against clinically isolated multi-drug resistant (MDR) microorganisms. It is suggested that biogenic synthesis of nanoparticles have wide-application in medicine and physical chemistry and it can produce with eco-friendly, easy downstream processing and rapid scale-up processing.

A mathematical model for analyzing the elasticity, viscosity, and failure of soft tissue: comparison of native and decellularized porcine cardiac extracellular matrix for tissue engineering.

The clinical success of tissue-engineered constructs commonly requires mechanical properties that closely mimic those of the human tissue. Determining the viscoelastic properties of such biomaterials and the factors governing their failure profiles, however, has proven challenging, although collecting extensive data regarding their tensile behavior is straightforward. The easily calculated Young's modulus remains the most reported mechanical measure, regardless of its limitations, even though single-relaxation-time (SRT) models can provide much more information, which remain scarce due to a lack of manageable tools for implementing these models. We developed an easy-to-use algorithm for applying the Zener SRT model and determining the elastic moduli, viscosity, and failure profiles of materials under different mechanical tests in a user-independent manner. The algorithm was validated on the data resulting from tensile tests on native and decellularized porcine cardiac tissue, previously suggested as a promising scaffold material for cardiac tissue engineering. This analysis yields new and more accurate measurements such as the elastic moduli and viscosity, the model's relaxation time, and information on the factors governing the materials' failure profiles. These measurements indicate that the viscoelasticity and strength of the decellularized acellular extracellular matrix (ECM) are similar to those of native tissue, although its elasticity and apparent viscosity are higher. Nonetheless, reseeding and culturing the ECM with mesenchymal stem cells was shown to partially restore the mechanical properties lost after decellularization. We propose this algorithm as a platform for soft-tissue analysis that can provide comparable and unbiased measures for characterizing viscoelastic biomaterials commonly used in tissue engineering.
