Background: Colorectal cancer is still challenging for scientists and healthcare professionals. Conventional treatment methods are associated with various limitations at a clinical bed and patient’s compliance. Novel nanocarrier based approaches opened a new window for improved therapy and new future perspective. Introduction: Cancer is the deadliest disease globally and is challenging to healthcare systems. Colorectal cancer (CRC) is the third most common cancer in the world, affecting all age groups and the most common cancer in 23 countries, as per the World Health Organization (WHO). Methods: In this review, we addressed nanocarriers based strategic treatment of colorectal cancer, major findings, limitations, and future perspective. For this, we seriously reviewed literature downloaded from prime sources such as Google Scholar, Web of Science, PubMed, and Publon. To filter the exact need of data, we used keyword alone in combination. Various relevant articles were obtained from the reference section of the selected papers. Results and Discussion: It is necessary to have an effective and targeted treatment option to control CRC compared to available remedies. Nanotechnology has been widely used to diagnose and treat several cancer types. Advances in nanomedicine and phytonanomedicine promoted novel identification methods to treat colorectal cancer patients. There are several nanocarriers recommended for clinical purposes. However, to date, only a few clinically approved nanocarriers can load anticancer moieties and selectively bind to cancer cells. Some nanocarriers transport and release treatments to the target colorectal area but provide few benefits. Conclusion: In this review, various nanoparticles (NPs) with unique properties have been discussed in relation to managing colorectal cancer, major outcomes of clinical trials, and successful patents published so far.

In this paper, we have proposed different deployment strategies and have applied area-wise clustering along with modified Ant Colony Optimization to minimize energy consumption. Background: Previously, some deployment strategies were used to enhance the lifetime of WSN. In our research, we have applied some novel deployment strategies like random, spiral, and S-pattern along with a novel area-wise clustering process to get better results than the existing literature, as shown in Table 4. Objective: The main objective of the research article is to enhance the lifetime of Wireless Sensor Network with the help of different deployment strategies like random, spiral, and S-pattern). A novel clustering process (i.e., area-wise clustering), and a Meta-heuristic algorithm (modified ACO) are applied. Methods: We have applied different methods for deployment strategies (random, spiral, and S-pattern). A novel clustering process (i.e., area-wise clustering), and a Meta-heuristic algorithm (modified ACO) are applied to get the desired results. Results: Random Deployment: 11.15 days to 15.09 days. Spiral Deployment: 11.25 days to 15.23 days. S-Pattern Deployment: 11.33 days to 15.33 days. Conclusion: In this paper, efficient Wireless Sensor Networks have been configured considering energy minimization as the prime concern. To minimize the energy consumption, a modified ACO algorithm has been proposed. In our work, the minimization of energy consumption leads to an increment of the lifetime of WSN to a significant margin theoretically. The obtained result has been compared with the existing literature and it has been found that the proposed algorithm produced a better result than the existing literature.

Background: Alcohol dependence is a significant public health problem, contributing to the global health burden. Due to its immense socio-economic burden, various psychosocial, psychological, and pharmacological approaches have attempted to alter the behaviour of the patient misusing or abusing alcohol, but their efficacy is modest at best. Therefore, there is a search for newer treatment approaches, including non-invasive brain stimulation in the management of alcohol dependence. We plan to study the efficacy of Prefrontal Cortex Transcranial direct current stimulation Treatment in Alcohol dependence syndrome (PreCoTTA). Methods: Two hundred twenty-five male patients with alcohol dependence syndrome will be randomized into the three study arms (2 active, left dorsolateral prefrontal cortex and left orbitofrontal cortex, and 1 sham) to receive a total of 14 tDCS sessions (10 continuous and 4 booster sessions). Data will be collected from these sessions at five different time points on clinical, neuropsychological and biochemical parameters. In addition, 225 healthy age and education matched controls will be administered the neuropsychological test battery at baseline for comparison with the patient group. Discussion: The proposed study aims to explore the use of non-invasive brain stimulation; tDCS as a treatment alternative. We also aim to overcome the methodological gaps of limited sample sizes, fewer tDCS intervention sessions, lack of long-term follow-ups to measure the sustainability of gains, and lack of comprehensive measures to track changes in functioning and abstinence after tDCS intervention. The main outcomes include clinical (reduction in cue-induced craving, time to first drink, and QFI); neuropsychological (risk-taking, impulsivity, and other neuropsychological domains), and biochemical markers (BDNF, leptin and adiponectin). The findings of the study will have translational value as they may help to improve the clinician’s ability to effectively manage craving in patients with alcohol dependence syndrome. Furthermore, we will have a better understanding of the neuropsychological and biochemical effects of non-invasive brain stimulation techniques which are of interest in the comprehensive treatment of addiction disorders. Trial registration: The study has been registered with the Clinical Trials Registry-India (CTRI/ 2020/09/027582) on September 03rd 2020.

Water quality assessment relies mostly on physico-chemical-based characterization; however, eutrophication and climate change advocate the abundance of toxic microcystins (MCs) producing cyanobacteria as emerging bio-indicator. In the present study, a spatial-temporal analysis was carried out at ten sampling sites of Prayagraj and Varanasi during June 2017 and March 2018 to determine the Ganga River water quality using physico-chemical parameters, cyanobacteria diversity, detection of MCs producing strains and MC-LR equivalence. Coliform bacteria, COD, NO3-N, and phosphate are the significant contaminated parameters favoring the growth of putative MCs producing cyanobacteria. National Sanitation Foundation WQI (NSFWQI) indicates water quality, either bad or medium category at sampling points. The morphological analysis confirms the occurrence of diverse cyanobacterial genera such as Microcystis, Anabaena, Oscillatoria, and Phormidium. PCR amplification affirmed the presence of toxic microcystin (mcy) genes in uncultured cyanobacteria at all the sampling sites. The concentration of MC-LR equivalence in water samples by protein phosphatase 1 inhibition assay (PPIA) and high-performance liquid chromatography (HPLC) methods was observed in the range of 23.4–172 ng/L and 13.2–97.5 ng/L respectively which is lower than the harmful exposure limit by World Health Organization (WHO). Ganga isolate 1 was identified as Microcystis based on partial 16S rDNA sequence and its toxicity was confirmed due to presence of mcy genes and MCs production potential. These findings suggest the presence of MCs producers as new emerging parameter to monitor water quality index and identification up to species level will be valuable for restoration strategies of river Ganga.

Background: The negative appraisal of emotional stimuli is a feature of social anxiety disorder (SAD). People with SAD demonstrate deficits in neurocognitive performance while performing tasks of attention. However, the relationship between attentional control, working memory, and threat perception in SAD has not been studied well. The present study aimed to identify patterns of threat perception in relation to performance on attention and visuospatial working memory tasks in individuals with SAD. Methods: Subjects with SAD ( n = 27) and a healthy comparative (HC) group ( n = 26) completed tasks of sustained and focused attention, visuospatial working memory, computerized emotion identification, and pictorial emotional Stroop. Results: The SAD group had decreased performance in the domains of sustained (P = 0.001) and focused attention (P = 0.04). They also had an enhanced threat perception as demonstrated by greater reaction time to anger (P = 0.03), lower emotion recognition accuracy (P = 0.05), and higher over-identification of the threat to neutral and nonthreatening faces. However, the Stroop effect was not demonstrated across the groups. No group difference was seen in the performance on the visuospatial working memory tasks. Lower focused attention was significantly correlated with higher emotional threat perception (ETP; P = 0.001) in the SAD group. Conclusion: People with SAD have greater deficits in attention processing and ETP. The attention deficits were associated with enhanced ETP in social anxiety. The link between threat perception and cognitive functions would aid in a better understanding of SAD and in planning appropriate intervention.

The present investigation is an attempt to study hydrocarbon source potential of early Paleogene lignites of Kapurdi, Barmer Basin. The samples collected from the working mines have been subjected to petrographic and geochemical analyses. The petrographic study includes both maceral as well as microlithotype analyses whereas geochemical study includes proximate and ultimate analyses. Besides, rock eval pyrolysis, FTIR and NMR studies have also been carried out. The analytically generated data were also correlated and checked with empirical equations. The study shows that these lignites of Barmer Basin are rich in kerogen type-III organic matter and contain high concentration of reactive macerals (huminite + liptinite) to the tune of ∼98% (mineral matter free basis) and they have attained low maturity (Rmax is 0.43%). These lignites have a fairly high conversion factor (95–97%) and oil yield (65–67%) which is also supported by the rock-eval data. Further, 1H and C13 shifts of NMR also suggest a high potential of hydrocarbon of Kapurdi lignites.

Objectives Peritoneal tuberculosis can mimic advanced abdominal malignancy. We describe clinical and laboratory characteristics in a series of female patients with peritoneal tuberculosis who were referred to a tertiary cancer center with a diagnosis of suspected advanced ovarian/primary peritoneal cancer. Materials and Methods Details of clinical features, laboratory results including serum tumor markers, radiological findings, and ascitic fluid evaluation were retrospectively collected from hospital records for patients diagnosed to have peritoneal tuberculosis and reported descriptively. Statistical Analysis Descriptive statistics was performed using SPSS Statistics for Windows software, version 20.0 (SPSS, Chicago, Illinois). Results Between January 2009 and December 2017, 120 patients of peritoneal tuberculosis with a median age 41 years (range, 15–79 years) were identified. Of these 112 (93.3%; 95% CI 88.9–97.8%) patients had ascites and 63 (52.5%; 95% CI 43.6–61.4%) had adnexal mass at presentation. Mean serum cancer antigen 125 (CA-125) level was 666.9 (range, 38–18,554) U/mL. Ascitic fluid was negative for malignant cells in all patients and lymphocyte rich exudate was seen in 103 (91.9%; 86.9–97.0%) patients. Ascitic fluid adenosine deaminase (ADA) level was more than 40 U/L in 107 (95.5%; 95% CI 91.7–99.4%). Ascitic fluid Ziel–Neelsen staining was positive in 4/62 (6.5%; 95% CI 0.3–12.6%) patients while ascitic fluid culture examination for mycobacterium tuberculosis was positive in 7/59 (11.9%; 95% CI 3.6–20.1%) patients. The diagnosis of tuberculosis was based on image-guided biopsy in 44 (36.7%) patients, surgical biopsy in 8 (6.7%) patients, and a combination of clinicoradiological and laboratory features in 68 (56.7%) patients. All patients received standard antitubercular treatment. Conclusions The study results suggest that peritoneal tuberculosis has clinical, radiological, and serological profile which may mimic advanced ovarian/primary peritoneal cancer. Peritoneal tuberculosis should be considered in the differential diagnosis of advanced abdominal malignancy.

Patients whose with facial appearance involves dental anomalies and malocclusion face an increased prevalence of various psychosocial problems such as a high level of social anxiety, social avoidance, and low quality of life. This study investigates the patients with craniofacial anomalies and their psychological adjustment concerning the facial and dental appearance. It also evaluates the expectations of this patient group from the orthodontic treatment. Two steps were done in this study. In the first step, translation and validation of the Derriford Appearance Scale (DAS59), The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and Patient Expectation from the Orthodontic Treatment (PEOTQ) questionnaires into Maithili were done, and then the main study was conducted using these valid questionnaires. This was a cross-sectional study conducted on the patients with congenital craniofacial anomalies visiting the orthodontics department of Patna Dental College and Hospital, Patna (Bihar). All the patients received the Maithili DAS, Maithili PIDAQ and Patients' Expectation from the orthodontic treatment questionnaires. The Maithili version of DAS59, PIDAQ and PEOTQ were developed with outstanding reliability and validity. A significant difference between PIDAQ (p

This work deals with the electromechanical analysis of the Hemispherical Resonator Gyroscope (HRG). The HRG is a type of Coriolis vibratory gyroscope (CVG), which uses Coriolis force to measure the input angular rate. For any CVG drive and sense mode, frequencies play a critical role, which decides the sensitivity and bandwidth of a sensor. In this study, we carry out modal analysis to evaluate the natural frequencies and corresponding mode shapes of an HRG. As HRG is an electromechanical structure, the device is driven at resonance in the drive direction, and the Coriolis force leads to motion in the sense direction. In this study, we present the piezoelectric based HRG; coupled field simulations are carried out to evaluate the performance characteristics of a sensor.

Locally advanced high-grade leiomyosarcomas (LMS) with visceral involvement are difficult to manage. Here, we present a case of locally advanced high-grade sarcoma where total pelvic exenteration was undertaken to achieve complete cytoreduction. A 54-year-old lady with a prior history of hysterectomy and bilateral salpingoophorectomy done 8 years back for heavy menstrual bleeding presented to us with an abdomino-pelvic mass. Magnetic resonance imaging of the abdomen suggested large heterogeneous pelvic mass displacing urinary bladder anteriorly and abutting recto-sigmoid posteriorly with no luminal involvement. There was bilateral hydronephrosis. Computed tomography of the thorax revealed no evidence of metastatic disease. A review of previous biopsy and a repeat ultrasound-guided biopsy from the pelvic mass done at our institute suggested spindle-cell neoplasm. In view of pelvis confined disease in a young woman with well-preserved general condition, decision for surgical excision was taken. She underwent total pelvic exenteration with en bloc removal of mass, bladder, and involved portion of recto-sigmoid as the disease was infiltrating both the bladder and the recto-sigmoid. Her postoperative course was turbulent, but she recovered fully and was discharged 20 days after surgery. The operative specimen histopathology revealed high-grade LMS. She received four cycles of adjuvant chemotherapy and thereafter was kept on follow-up. Although she was clinically doing well, her general condition never improved beyond Eastern cooperative oncology Group 2. She also had persistent depressive symptoms. After 14 months of completion of treatment, she recurred with a huge abdominal disease. In view of her general condition and huge disease volume, decision was taken for supportive care only. LMS in advanced stages are difficult to manage. Even after aggressive management with radical exenterative surgery and chemotherapy, we could achieve only temporary control of locally advanced LMS.

Background:Cyanobacteria are excellent model to understand the basic metabolic processes taking place in response to abiotic stress. The present study involves characterization of a hypothetical protein Alr0765 of Anabaena PCC7120 comprising CBS-CP12 domain and deciphering its role in abiotic stress tolerance.Methods:Molecular cloning, heterologous expression and protein purification using affinity chromatography was performed to obtain native purified protein Alr0765. Energy sensing property of Alr0765 was inferred from its binding affinity with different ligand molecules as analyzed by FTIR and TNP-ATP binding assay. AAS and real time-PCR were applied to evaluate the iron acquisition property and cyclic voltammetry was employed to check redox sensitivity of the target protein. Transcript level under different abiotic stresses as well as spot assay, CFU count, ROS level and cellular H2O2level were used to show potential role of Alr0765 in abiotic stress tolerance. In-silico analysis of Alr0765 included molecular function probability analysis, multiple sequence analysis, protein domain and motif finding, secondary structure analysis, protein ligand interaction, homologous modeling, model refinement and verification and molecular docking was performed with COFACTOR, PROMALS-3D, InterProScan, MEME, TheaDomEx, COACH, Swiss modeller, Modrefiner, PROCHECK, ERRAT, MolProbity, ProSA, TM-align, and Discovery studio respectively.Results:Transcript levels of alr0765 significantly increased by 20, 13, 15, 14.8, 12, 7, 6 and 2.5 fold when Anabaena PCC7120 treated with LC50 dose of heat, arsenic, cadmium, butachlor, salt, mannitol (drought), UV-B, and methyl viologen respectively, with respect to control (untreated). Heterologous expression resulted in 23KDa protein observed on the SDS-PAGE. Immunoblotting and MALDI-TOF-MS/MS followed by MASCOT search analysis confirmed the identity of the protein and ESI/MS revealed the purified protein was a dimer. Binding possibility of Alr0765 with ATP was observed with almost 6-fold increment in relative fluorescence during TNP-ATP binding assay with a ƛ max of 538 nm. FTIR spectra revealed modification in protein confirmation upon binding of Alr0765 with ATP, ADP, AMP and NADH. A 10-fold higher accumulation of iron was observed in digests of E. coli with recombinant vector after induction as compared to control affirms the iron acquisition property of protein. Moreover, generation of redox potential of 146 mV by Alr0765 suggested its probable role in maintaining redox status of the cell under environmental constraints. As per CFU count recombinant E. coli BL21 cells showed about 14.7, 7.3, 6.9, 1.9, 3, 4.9 fold higher number of colonies under heat, cadmium (CdCl2), arsenic (Na3AsO4), salt (NaCl), UV-B and drought (mannitol) respectively compared to pET21a harboring E. coli BL21 cells. Deterioration in cellular ROS level and total cellular H2O2concentration validated stress tolerance ability of Alr0765. In-silico analysis unraveled novel findings and attested experimental findings in determining the role of Alr0765.Conclusion:Alr0765 is a novel CBS-CP12 domain protein that maintains cellular energy level and iron homeostasis provide tolerance against multiple abiotic stresses.

Dental health plays an imperative role in the general health and well-being of an individual. Terminally ill patients due to a compromised immune response are susceptible to a wide array of oral complications, which may affect their ability to speak and chew, leading to malnutrition. The present study was conducted to evaluate dental health and various oral manifestations in terminally ill patients. One hundred twenty terminally ill patients hospitalized with diseases of the respiratory tract, gastrointestinal tract, circulatory system, liver, and endocrinal disorders were included in the study. The evaluation of oral manifestations and their prevalence was done by a single examiner. The oral health was evaluated according to symptoms exhibited by the patients and clinical presentation. Of the patients included in the study, 78 were male, and 42 were female. All the individuals were adults between 25 to 55 years of age. Out of 120 admitted terminally ill patients, 27 subjects had respiratory diseases, 17 had gastrointestinal disorders, 5 had disorders of the circulatory system, 39 had liver disorders, and 32 had endocrine disorders. A need for added comprehension is mandatory to link the inter-relationships between dentistry and medicine to further perk up the management of the overall health of patients, which will further reinforce the partnership between dental and medical communities.

Background Ovarian germ cell tumours constitute a heterogeneous group of neoplasm with malignant potential being seen in 5% of cases. There is limited data on treatment outcomes of patients with malignant ovarian germ cell tumours (MOGCT). Here, we present our hospital audit of patients with MOGCT. Material and methods This is a retrospective data review of patients with MOGCT treated between May 2011 and December 2019. Patients were treated with staging laparotomy and adjuvant chemotherapy, wherever applicable. Surveillance was allowed for those at low risk for recurrence. Clinicopathologic features and treatment details were recorded, and survival analysis was performed. Results Sixty-five patients with a median age of 25 years (range: 11-52 years) were treated during the study period. The most common histology was immature teratoma in 35.3% of cases. International Federation of Gynecology and Obstetrics stage IC was the most common stage of presentation (47%). Surveillance was advised for 12.3% of cases. Systemic therapy was given in 51 (78%) patients. At a median follow-up of 46 months (range: 1-109 months), the median progression-free survival (PFS) was not reached. Five-year PFS was 79.3% (95% CI: 65.8-88). The most common toxicity was febrile neutropenia (22%) among those who received systemic therapy. Conclusion Immature teratoma was the most common histology in our series. The majority presented in the early stage. MOGCT is a highly curable disease with surgery and systemic therapy.

The present study is an attempt to know the temporal and spatial distribution of geochemical components in the lignite deposit of Kapurdi, Barmer Basin (Rajasthan). Lignite samples have been subjected to proximate, ultimate and elemental analyses, and determination of mineral carbon (MINC%). Besides, various minerals and functional groups have been analyzed through X-ray diffraction (XRD) and Fourier transforms infrared spectroscopy (FTIR). Selected environmentally sensitive and potential hazardous elements like Cu, Cd, Zn, Ni, Cr, Pb, Mn, Al, Fe and Co are determined using atomic absorption spectrophotometer (AAS). To know the association of minerals with organic matter, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) has also been carried out. The concentration of Co, Ni, Cd, Pb, Na, and K is high when compared with world average and is main concern for the environmental and health hazards. The elements like Fe, Ca, Mg, Zn, and Pb have shown increasing trend from top to bottom of the lignite seam with some fluctuations in the values in few bands whereas others do not follow a definite trend of variation along the seam profile.

Abiotic stresses enhance cellular reactive oxygen species (ROS) level which results in toxic methylglyoxal (MG) production. Glyoxalases catalyze the conversion of toxic MG into non-toxic lactic acid whose properties and function are still unknown in cyanobacteria. This is the first attempt to characterize All0580 from Anabaena sp. PCC7120 as GlyII using in silico and wet lab approaches. Data of functional complementation of E. coli GlyII mutant (ΔgloB), enzyme kinetics and ESI-MS analysis suggested that All0580 harbors distinctive GlyII activity. The catalytic efficiency of All0580 (3 × 106 M−1 s−1) is higher than Arabidopsis GlyII. AAS analysis revealed the presence of a binuclear Zn/Fe centre in All0580 active site. The qRT-PCR of the target gene revealed maximum up-regulation in salinity followed by drought, arsenic, heat, and UV-B stresses. BL21/pET-21a-all0580 showed 1.5 to 10 fold increased growth and up to 4 fold decreased intracellular MG level as compared to BL21/pET-21a cells under various abiotic stresses and MG. A 39% drop in ROS generation by BL21/pET-21a-all0580 under MG stress suggested its potential to manage MG toxicity. Above attributes suggest that the hypothetical protein All0580 is a novel GlyII of cyanobacteria which heterologously confers tolerance to multiple abiotic stresses in E. coli.

In- silico and functional genomics approaches have been used to determine cellular functions of two hypothetical proteins All1122 and Alr0750 of Anabaena sp. PCC 7120. Motif analysis and multiple sequence alignment predicted them as typical α/β ATP binding universal stress family protein-A (UspA) with G-(2×)-G-(9×)-G(S/T) as conserved motif. qRT-PCR data under UV-B, NaCl, heat, As, CdCl2, mannitol and methyl viologen registered approximately 1.4 to 4.3 fold induction of all1122 and alr0750 thus confirming their multiple abiotic stress tolerance potential. The recombinant E. coli (BL21) cells harboring All1122 and Alr0750 showed 12-41% and 23-41% better growth respectively over wild type control under said abiotic stresses thus revalidating their stress coping ability. Functional complementation on heterologous expression in UspA mutant E. coli strain LN29MG1655 (ΔuspA::Kan) attested their UspA family membership. This study tempted us to suggest that recombinant Anabaena PCC 7120 over expressing all1122 and alr0750 might contribute to the nitrogen economy in paddy fields experiencing array of abiotic stresses including drought and nutrient limitation.

Soil biota plays a critical role in the functioning of ecosystem. In terrestrial regions nitrogen is limiting constituent that determines the growth of plants, primary productivity therefore net productivity of an ecosystem can be controlled by combined activities of microflora and fauna of soil which facilitate the conversion of nitrogen to usable forms. Varieties of microorganisms that are highly diverse in terms of taxa and activities are engaged in N cycle including nitrogen fixers, ammonia oxidizers, autotrophic nitrifiers, heterotrophic nitrifiers, anammox bacteria, denitrifiers, archaea, and fungi. In addition, soil fauna perform the significant role in maintaining the structure and function of soil ecosystems including organic matter mineralization, productivity regulation, and nutrient cycling (N, S, C). Soil fauna generally includes nematodes, micro-arthopods, and macrofauna. These soil fauna play pivotal role in nitrogen cycling via performing mineralization process. In order to improve the effectiveness of agricultural systems and practices that ultimately lead to better productivity of food, understanding of different phases of N cycle along with activities of microflora and fauna is necessary. In this regard, present chapter centers on exploring variety of soil microflora and fauna and their potential roles in nitrogen cycle. Here, we also review critical insights related to various processes of nitrogen cycling in soil ecosystem and their ecological importance.

Background: Thought disorder is considered to be central to the core disturbances in schizophrenia and was described by Goldstein as aberrant “concept formation.” Executive dysfunction is another core deficit in schizophrenia. With a greater emphasis on psychopathology in nosological systems, the classical thought disorder receives less prominence. The present study aimed to understand the association between classical thought disorder (aberrant concept formation and concrete abstraction) and executive dysfunction. Methods: Thirty patients with schizophrenia and thirty healthy subjects, matched on age, gender, education, and socioeconomic status, were screened using MINI 5.0, following which they were assessed on object sorting test (OST) and selected tests for executive functions (EFs). Results: Individuals with schizophrenia were found to have significantly decreased performance on all domains of EFs and OST. Total peculiar scores on OST were significantly associated with mental speed, focused attention, and divided attention. Total impoverished scores on OST was significantly associated with focused attention, sustained attention, planning, set shifting, perseveration, and concept formation. Conclusion: Several correlations, among performance on OST and neuropsychological tests, suggest that patterns of responses on OST can point to underlying executive dysfunction. Both thought disorder and executive dysfunction mirror similar constructs. This similarity represents a conceptual bridge between the classical and contemporary descriptions of the core deficits in schizophrenia.

This study examined the efficacy of mindfulness based cognitive therapy on children (MBCT-C) with anxiety. Two hundred and forty children were screened, of which 52 (25 boys and 27 girls) with anxiety were randomly allocated to either MBCT-C or group therapy (GT including cognitive behavioral principles). Both groups were rated on the Spence Children's Anxiety Scale and Emotion Regulation Questionnaire–Child and Adolescent, pre- and 12 weeks post-interventions. MBCT-C was found to be more effective than GT in improving anxiety among children (between-group effect size Cohen's d 1.05) and as effective as GT in reducing emotion suppression for effective emotion regulation. This study provides support for MBCT-C as an effective group intervention for children with anxiety.

Brain metastasis in recurrent setting is a rare phenomenon in gynecological cancers. Even rarer is the occurrence of second intracranial primary. All these women generally will present with subtle neurological symptoms. However due to its rarity and non-specificity of symptoms, these often tend to get missed. Here we present a case series of six women of known gynecological cancers who presented to our department with brain space occupying lesions (SOLs). Five among these were primary ovarian cancers who had recurred with brain metastasis. The sixth one was a case of endometrial cancer treated in the past for recurrence and now presenting with a second primary. MRI brain was used to confirm diagnosis in all of them. Two were inoperable disease due to diffused parenchymal brain metastasis. They received palliative care and died subsequently. Four were initially managed with surgical resection with uneventful postoperative outcome. This was followed by adjuvant treatment in the form of whole brain radiotherapy (WBRT) with or without chemotherapy. Three of them successfully completed their adjuvant treatment and kept on follow-up whereas the fourth progressed on treatment. Their long-term outcomes are yet to be seen. Selected cases with brain metastasis merits aggressive approach with surgical removal of tumor followed by adjuvant treatment.

Background About two-third of new drugs reveal low solubility in water due to that; it becomes difficult for formulation scientists to develop oral solid dosage forms with a pharmaceutically acceptable range of therapeutic activity. In such cases, S-SMEEDS are the best carrier used universally for the delivery of hydrophobic drugs. SEDDS were also used, but due to its limitations, S-SMEDDS used widely. These are the isotropic mixtures of oils, co-solvents, and surfactants. S-SMEDDS are physically stable, easy to manufacture, easy to fill in gelatin capsules as well as improves the drug bioavailability by releasing the drug in the emulsion form to the gastrointestinal tract and make smooth absorption of the drug through the intestinal lymphatic pathway. Methods We took on the various literature search related to our review, including the peer-reviewed research, and provided a conceptual framework to that. Standard tools are used for making the figures of the paper, and various search engines are used for the literature exploration.In this review article the author discussed the importance of S-SMEDDS, selection criteria for excipients, pseudo-ternary diagram, mechanism of action of S-SMEDDS, solidification techniques used for S-SMEDDS, Characterization of SEDDS and S-SMEDDS including Stability Evaluation of both and future prospect concluded through recent findings on S-SMEDDS on Cancer as well as a neoteric patent on S-SMEDDS Results: Many research papers discussed in this review article, from which it was found that the ternary phase diagram is the most crucial part of developing the SMEDDS. From the various research findings, it was found that the excipient selection is the essential step which decides the strong therapeutic effect of the formulation. The significant outcome related to solid-SMEDDS is less the globule size, higher would be the bioavailability. The adsorption of a solid carrier method is the most widely used method for the preparation of solid-SMEDDS. After review of many patents, it is observed that the solid-SMEDDS have a strong potential for targeting and treatment of a different type of Cancer due to their property to enhance permeation and increased bioavailability. Conclusion S-SMEEDS are more acceptable pharmaceutically as compare to SEDDS due to various advantages over SEDDS viz stability issue is prevalent with SEDDS. A number of researchers had formulated S-SMEDDS of poorly soluble drugs and founded S-SMEDDS as prospective for the delivery of hydrophobic drugs for the treatment of Cancer. S-SMEEDS are grabbing attention, and the patentability on S-SMEDDS is unavoidable, these prove that S-SMEEDS are widely accepted carriers. These are used universally for the delivery of the hydrophilic drugs and anticancer drugs as it releases the drug to the gastrointestinal tract and enhances the systemic absorption. Abstract: Majority of active pharmaceutical ingredients (API) shows poor aqueous solubility, due to that drug delivery of the API to the systemic circulation becomes difficult as it has low bioavailability. The bioavailability of the hydrophobic drugs can be improved by the Self-emulsifying drug delivery system (SEDDS) but due to its various limitations, solid self-micro emulsifying drug delivery systems (S-SMEDDS) are used due to its advantages over SEDDS. S-SMEDDS plays a vital role in improving the low bioavailability of poorly aqueous soluble drugs. Hydrophobic drugs can be easily loaded in these systems and release the drug to the gastrointestinal tract in the form of fine emulsion results to In-situ solubilisation of the drug. In this review article the author's gives an overview of the solid SMEDSS along with the solidification techniques and an update on recent research and patents filled for Solid SMEDDS.

Abstract: Nanomedicine is a branch of healthcare, which has many clinical applications. Nanoscale science has to presume an attractive slot for research in drug delivery as nanocarriers either through active or passive targeting approaches to the cell-specific drug delivery. Liposomes, solid-lipid nanoparticles, dendrimers, polymeric nanoparticles, mesoporous silica nanoparticles, inorganic nanoparticles, nanotubes, quantum dots, and nanofibers are nanocarriers that are proved too smart nano-based drug delivery system. The nanoparticulate system shows high stability, high specificity, high efficacy, liability to form in different dosage, used through different routes, as well as the ability to deliver hydrophobically as well as hydrophilic drugs. These nanoparticulate systems are showing wider applications to cure the disease through nanomedicines and biomedical applications viz. chemical and biological sensors, information storage systems, magneto-optic, optical devices, and fiber-optic systems. In this review article, the author describes the various smart nano-based drug delivery system along with their endocytic pathways used for the uptake of nanoparticles.

Chylothorax is an uncommon entity associated with various processes that damage or obstruct the thoracic duct and its tributaries causing chyle to leak into the pleural space. We reported the case of a 20-year-old girl who presented with bilateral chylothorax secondary to central vein thrombosis in a case of germ cell tumour of the ovary. Her contrast-enhanced computerised tomography for thorax and abdomen revealed abdominopelvic mass with ascitis, bilateral pleural effusion, mediastinal lymphadenopathy and thrombosis of left internal jugular, brachiocephalic veins, right subclavian vein and bilateral pulmonary artery lobar branches. Germ cell tumour ovary was diagnosed in view of her characteristic tumour marker pattern. Patient was managed conservatively with low molecular weight heparin, pigtail intercostal drain and diet modification. Chemotherapy was started as soon as she was hemodynamically stable, which helped in early resolution of precipitating factor. There was a complete resolution of the thrombosis. She responded to chemotherapy and successfully went on to have fertility-preserving surgery. There was no residual tumour in surgical specimen, and she has been kept on follow-up in the post-operative period. At 6-month follow-up, she continues to be disease-free.

Oral submucous fibrosis is a chronic progressive scarring disease of oral cavity and oropharynx characterized by epithelial atrophy and juxta epithelial inflammatory reaction with progressive fibrosis of the lamina propria and deeper connective tissue. The resulting stiffness of the oral mucosa then causes a progressive decrease in mouth opening. Hence based on above findings the present study was planned for Clinical Assessment of Occurrence of Oral Submucous Fibrosis in Patients from Patna Medical College & Hospital. The present study was planned in Department of Oral Pathology, Patna Dental College & Hospital, Patna. Total 50 cases of the patient diagnosed with the Oral Sub mucous Fibrosis (OSMF) were evaluated in the present study. History, examination and investigation of patients were done in detail as per predesigned proforma. Histopathological examination of biopsy tissue from oral mucosa was done in patients who had taken pre-therapy and post-therapy (if and when required). X-ray of temporomandibular joint was requested (whenever needed). OSMF is a commonly occurring and widely spread premalignant condition increasingly affecting the youth. The occurrence of OSMF in gutkha chewers is far faster and more severe as compared in other forms of areca nut products chewers. The easy availability and promotions of these areca nut products especially gutkha and pan masala outside the schools colleges and social places has impacted younger population in India which has led to the increased occurrence of OSMF.
