Abstract
BACKGROUND Bacterial vaginosis (BV) is a common clinical manifestation of a perturbed vaginal ecology associated with adverse sexual and reproductive health outcomes if left untreated. The existing diagnostic modalities are either cumbersome or require skilled expertise, warranting alternate tests. Application of machine-learning tools to heterogeneous and high-dimensional multi-omics datasets finds promising potential in data integration and may aid biomarker discovery. OBJECTIVES The present study aimed to evaluate the potential of the microbiome and metabolome-derived biomarkers in BV diagnosis. Interpretable machine-learning algorithms were used to evaluate the utility of an integrated-omics-derived classification model. METHODS Vaginal samples obtained from reproductive-age group women with (n = 40) and without BV (n = 40) were subjected to 16S rRNA amplicon sequencing and LC-MS-based metabolomics. The vaginal microbiome and metabolome were characterized, and machine-learning analysis was performed to build a classification model using biomarkers with the highest diagnostic accuracy. RESULTS Microbiome-based diagnostic model exhibited a ROC-AUC (10-fold CV) of 0.84 ± 0.21 and accuracy of 0.79 ± 0.18, and important features were Aerococcus spp., Mycoplasma hominis, Sneathia spp., Lactobacillus spp., Prevotella spp., Gardnerella spp. and Fannyhessea vaginae. The metabolome-derived model displayed superior performance with a ROC-AUC of 0.97 ± 0.07 and an accuracy of 0.92 ± 0.08. Beta-leucine, methylimidazole acetaldehyde, dimethylethanolamine, L-arginine and beta cortol were among key predictive metabolites for BV. A predictive model combining both microbial and metabolite features exhibited a high ROC-AUC of 0.97 ± 0.07 and accuracy of 0.94 ± 0.08 with diagnostic performance only slightly superior to the metabolite-based model. CONCLUSION Application of machine-learning tools to multi-omics datasets aid biomarker discovery with high predictive performance. Metabolome-derived classification models were observed to have superior diagnostic performance in predicting BV than microbiome-based biomarkers.

Abstract
BACKGROUND Admission cardiotocography (CTG) used for fetal heart rate monitoring is an easy, cost-effective, non-invasive screening method for fetal well-being. OBJECTIVES To evaluate the role of admission CTG in predicting fetal hypoxia in term antenatal women during labour ward admission and to correlate the results with perinatal and maternal outcomes. MATERIAL AND METHODS The present prospective observational study was conducted in the Obstetrics and Gynecology Department of the rural tertiary centre in Northern India over one year on 100 term antenatal women admitted to the labour ward in the first stage of labour. Participants were subjected to admission CTG for 20 minutes, and the pattern of fetal heart rate (reactive, suspicious, ominous) was recorded. Perinatal and maternal outcomes were assessed based on the fetal heart rate pattern on the admission CTG. RESULTS Of 100 term antenatal women, 51 were low-risk and 49 were high-risk cases. In the low-risk group, 92.16% had reactive traces, 3.92% suspicious and 3.92% ominous traces on admission CTG, whereas, in the high-risk group, 40.81% had reactive, 32.65% suspicious and 26.54% ominous tracing (p < 0.0001). The most common mode of delivery in both groups with ominous tracing was cesarean section (p = 0.0001). Abnormal CTG was significantly associated with adverse perinatal outcomes including poor one-minute Apgar scores (p < 0.05), need for resuscitation and NICU admission (p < 0.05). The specificity and negative predictive value of admission CTG in low- and high-risk groups were 97.9% and 93.6%, and 85.0% and 85.0%, respectively. CONCLUSION Admission CTG is an effective, inexpensive, non-invasive technique to detect fetal hypoxia in low-and high-risk pregnancies in developing countries with an increased workload.

Abstract
Abstract
Background
Psychosis is a complex mental illness divided by positive symptoms, negative symptoms, and cognitive decline. Clinically available medicines are associated with some serious side effects which limit their use. Treatment with flavonoids has been associated with delayed onset and development, decreased risk, or increased improvement of various neuropsychiatric disorders including psychosis with negligible side effects.
Therefore, the present study was aimed to investigate the protective effects of hesperidin (flavonoid) alone or its combination with coenzyme Q10 against ketamine-induced psychotic symptoms in mice.
Results
Ketamine (50 mg/kg, i.p.) was given for 21 days to induce psychosis in Laca mice of either sex. Locomotor activity and stereotypic behaviors, immobility duration (forced swim test), and increased transfer latency (elevated plus maze) were performed to test the effect of hesperidin (50 mg/kg, 100 mg/kg, 200 mg/kg, p.o.) and coenzyme Q10 (20 mg/kg, 40 mg/kg, p.o.) and combination of hesperidin + coenzyme Q10 followed by biochemical and mitochondrial complexes assays. For 21 days, ketamine (50 mg/kg, i.p.) administration significantly produced increased locomotor activity and stereotypic behaviors (positive symptoms), increased immobility duration (negative symptoms) and cognitive deficits (increases transfer latency) weakens oxidative defense and mitochondrial function. Further, 21 days’ administration of hesperidin and coenzyme Q10 significantly reversed the ketamine-induced psychotic behavioral changes and biochemical alterations and mitochondrial dysfunction in the discrete areas (prefrontal cortex and hippocampus) of mice brains. The potential effect of these drugs was comparable to olanzapine treatment. Moreover, the combination of hesperidin with coenzyme Q10 and or a combination of hesperidin + coenzyme Q10 + olanzapine treatment did not produce a significant effect compared to their per se effect in ketamine-treated animals.
Conclusions
The study revealed that hesperidin alone or in combination with coenzyme Q10 could reduce psychotic symptoms and improve mitochondrial functions and antioxidant systems in mice, suggesting neuroprotective effects against psychosis.

Abstract
Introduction: Perioperative shivering after spinal anaesthesia is a common complication. Ketamine and tramadol are routinely used to prevent perioperative spinal shivering. Ketamine has the side-effect of delirium while tramadol causes nausea and vomiting. Dexmedetomidine an alpha2 agonist is superior to tramadol and ketamine in view of better central vasoconstrictor tone regulation and less sympathetic activity. Aim: To compare the efficacy, effect on haemodynamics, and any adverse effects of tramadol, ketamine and dexmedetomidine when used prophylactically to prevent perioperative shivering after spinal anaesthesia. Materials and Methods: This, randomised, clinical study recruited adult patients aged 18 to 65 years, of American Society of Anaesthesiologists (ASA) I and II, of both genders undergoing surgery under spinal anaesthesia between February 2018 and August 2018. A total of 120 patients were assigned to four groups: T, D, K, and N, to receive Tramadol 0.5 mg/kg or Dexmedetomidine 0.5 μg/kg or Ketamine 0.25 mg/kg or normal saline 5 mL, respectively. Each study drug was diluted to 5 mL using normal saline and administered as a slow intravenous (iv) bolus injection five minutes before spinal anaesthesia. Patients received subarachnoid block in L3-4 or L4-5 space in sitting position with 0.5% hyperbaric bupivacaine 15 mg. Patients were monitored for shivering, (using a four-point scale), level of consciousness, heart rate, SpO2 , respiratory rate, non invasive blood pressure, nausea and vomiting, at intervals of every five minutes for the first 30 minutes and every 15 minutes for the remaining observation period. Results: Dexmedetomidine (n=0) offered lower incidence of shivering prevention after spinal anaesthesia than ketamine (n=2,6.6%), tramadol (n=10,33%) and normal saline groups (n=11,36.6%). Dexmedetomidine also provided the advantages of maintaining haemodynamics, respiratory rate, and consciousness, similar to ketamine or tramadol (p-value>0.05). Conclusion: Dexmedetomidine is superior to ketamine and tramadol for the prevention of shivering after spinal anaesthesia.

Abstract
Background While patients and families struggling with atopic dermatitis (AD) have documented concerns for a contributory role of skin care products in AD pathology, nearly all the skin microbiome studies to date have asked participants to avoid topical products (such as soaps or select medications) for the preceding days to weeks prior to sample collection. Thus, given the established role of the microbiome in AD, the interactions between topical exposures, dysbiosis and AD remains underrepresented in the academic literature. Objectives To address this knowledge gap, we expanded our previous evaluations to test the toxicological effects of a broader range of common chemicals, AD treatment lotions, creams and ointments using both health- and AD-associated strains of Roseomonas mucosa and Staphylococcus spp. Methods Use of in vitro culture techniques and mouse models were deployed to identify chemicals with dysbiotic or pre-biotic potential. A proof-of-concept study was subsequently performed in healthy volunteers to assess global microbiome shifts after exposure to select chemicals using dermatologic patch testing. Results Numerous chemicals possessed antibiotic properties, including many not marketed as anti-microbials. Through targeted combination of potentially beneficial chemicals, we identified combinations which promoted the growth of health-associated isolates over disease-associated strains in bacterial culture and enhanced microbe-specific outcomes in an established mouse model of AD; the most promising of which was the combination of citral and colophonium (often sold as lemon myrtle oil and pine tar). Additional studies would likely further optimize the combination of ingredients use. Similar results were seen in the proof-of-concept human studies. Conclusions Our results could offer a systematic, multiplex approach to identify which products carry dysbiotic potential and thus may guide formulation of new topicals to benefit patients with AD.

Abstract
Background: Periarticular infiltration (PAI) analgesia has been found to be an effective analgesia modality after total knee arthroplasty (TKA). Dexmedetomidine has many beneficial effects on postoperative analgesia by different routes, but studies on PAI are lagging. Aims and Objectives: In this study, we compared postoperative analgesia after PAI with dexmedetomidine versus ketorolac as an additive to ropivacaine after TKA. Setting and Design: This is a prospective, randomized, double-blind study conducted on 75 patients belonging to American Society of Anesthesiologists I to III, undergoing total knee arthroplasty, of either gender, belonging to American Society of Anesthesiologists I to III. Materials and Methods: After institutional ethics committee approval and written informed consent, patients were randomly allocated into three groups. Group C (n = 25) received cocktail of 60 mL ropivacaine (0.25%) infiltration with adrenaline 5 mL (0.1 mg.mL−1), Group D (n = 25) received additive dexmedetomidine 1 ug.kg−1 to above cocktail, and Group K (n = 25) received ketorolac 30 mg. Postoperatively pain by Visual Analog Scale, vitals, total duration of analgesia, need for rescue analgesia, sedation, patient satisfaction, mobilization time, and complications were recorded. Statistical Analysis: The Statistical Package for the Social Sciences version 20 was used for statistical analysis. Analysis of variance has been used to find the significance of study parameters between the three groups of patients. P < 0.05 was considered statistically significant. Results: Postoperative pain score was lesser in the ketorolac group (1.52 ± 0.71, P = 0.001) than the other two groups. Duration of analgesia was more with ketorolac (343.00 ± 144.45, P < 0.001) compared with the other two groups, and epidural activation timings (462 ± 235.84) were significantly delayed in Group K compared to Group C and Group D. There was no significant difference in mobilization time, patient satisfaction, and complications between the three groups. Conclusion: Ketorolac was a better additive to ropivacaine than dexmedetomidine for postoperative analgesia after TKA.

Abstract
Psoriasis is a chronic autoimmune skin disorder which involves complex interactions between genes, keratinocytes, T-cells and inflammatory cells. It affects 2-3% population worldwide. Molecular biology and cellular immunology of psoriasis, when linked with biotechnology and genetic studies can help researchers to understand the pathophysiology of psoriasis. T-cells activation, keratinocyte hyperproliferation, and angiogenesis are the core mechanisms entailed in the development of psoriasis lesion. Investigators are trying to overcome the challenges of complex pathophysiology pathways involved in this disorder. The different possible hypotheses for its pathophysiology such as growth factors, enzymes, inflammation, and genetic factors mediated pathophysiology have been described in the present review paper in detail. Clinically available drugs only control the symptoms of psoriasis but are not effective for the treatment of the disorder completely and are also associated with some side effects such as itching, renal disorders, hematologic, nonmelanoma skin cancer, pulmonary, gastrointestinal toxicity, etc. This paper made an effort to understand the pathophysiological targets, discuss the research done so far and the treatments available for the effective management of psoriasis.

Abstract
AIM OF THE STUDY Left Ventricular (LV) function and myocardial viability is the key predictor of prognosis after myocardial infarction. Management of ischemic cardiomyopathy (revascularization and or drugs alone) is the objective of this study. METHODOLOGY 72 patients were assigned to revascularization and medical management group based on the inclusion criteria Follow up was done upto 12 months with advanced imaging techniques (FDG PET and SPECT MPI analyses). RESULTS Subjects with significant viable myocardium, revascularization resulted in significant improvement in heart failure symptoms. The mean NYHA functional class improved from 2.9 ± 0.3 to 2.3 ± 0.5(mean ± SD) after 6 months of revascularization (p < 0.01). This improvement in functional class was maintained after 12 months of revascularization (2.0 ± 0.4 (mean ± SD). Subjects on medical management with a baseline NYHA functional class 2.7 ± 0.5, at 6 months of follow, there was no significant change in functional class (2.8 ± 0.3) (p<0.24). However at 12 months follow up functional class had dropped to 3.0 + 0.3, which was significant as compared to baseline (p <0.03). CONCLUSION coronary revascularization has a protective effect on patients with ischemic coronary who have viable myocardium and reversible myocardial ischemia as assessed by 18F-FDG PET and SPECT MPI Imaging.

Abstract
Human gut microbiome is a diversified, resilient, immuno-stabilized, metabolically active and physiologically essential component of the human body. Scientific explorations have been made to seek in-depth information about human gut microbiome establishment, microbiome functioning, microbiome succession, factors influencing microbial community dynamics and the role of gut microbiome in health and diseases. Extensive investigations have proposed the microbiome therapeutics as a futuristic medicine for various physiological and metabolic disorders. A comprehensive outlook of microbial colonization, host-microbe interactions, microbial adaptation, commensal selection and immuno-survivability is still required to catalogue the essential genetic and physiological features for the commensal engagement. Evolution of a structured human gut microbiome relies on the microbial flexibility towards genetic, immunological and physiological adaptation in the human gut. Key features for commensalism could be utilized in developing tailor-made microbiome-based therapy to overcome various physiological and metabolic disorders. This review describes the key genetics and physiological traits required for host-microbe interaction and successful commensalism to institute a human gut microbiome.

Abstract
Background and Aims: Laryngoscopy forms an important part of general anesthesia and endotracheal intubation. The aim of the present study was to compare the hemodynamic responses to Laryngoscopy and Intubation using Macintosh or McCoy or C-MAC Laryngoscope with M-Entropy module monitoring to ensure uniform and adequate depth of anesthesia, during and after intubation. Material and Methods: A prospective, randomised, comparative study was done and patients included were of 18 to 60 years, ASA (American Society of Anesthesiologist) physical status I and II of both sexes undergoing elective surgery under general anesthesia. They were assigned to three groups using simple randomisation, after securing IV (intravenous) access, standard monitoring and Entropy leads were attached. General anesthesia was administered with glycopyrrolate 0.1 mg, fentanyl 2 ug/kg and intravenous thiopentone, 4 mg/kg. Adequate muscle relaxation was achieved with atracurium 0.6 mg/kg IV. By titrating isoflurane concentration, Entropy maintained between 40 and 60, orotracheal intubation done, with Macintosh or McCoy or C-MAC blades according to simple randomisation. Size of laryngoscope blade, time taken for laryngoscopy and intubation were noted. Heart rate, blood pressure, RE (Response Entropy) and SE (State Entropy) were noted before and during induction and laryngoscopy and post intubation up to 5 minutes. Statistical analysis done using NCSS 9 version 9.0.8 statistical software. Results: Hemodynamic responses during laryngoscopy and intubation using Macintosh or McCoy or C-MAC laryngoscope were statistically insignificant (p > 0.05) between the three groups, provided the depth of anesthesia is maintained constant. Conclusions: It is the depth of anesthesia that decides the magnitude of hemodynamic responses and not the choice of laryngoscope.

Abstract
Introduction:
Cervical cancer is the most prevalent cancer in the world due to unusual
extension of cervical cell. Cervical cancer occurs due to exposure of HPV (Human papillomavirus).
According to WHO, it is the 4th most ordinary cancer in women. In 2018, approx 6.6% of
population was affected around the world and 570,000 new cases were reported. In low and
middle-income countries, 90% of cervical cancer deaths occur.
Methods:
Despite various factors that cause cervical cancer are included exposure to HPV,
dysregulation of CASPASE enzyme, elevated expression of IAPs (Inhibitor apoptotic protein), E6
and E7 gene of HPV, inhibition of p53, BAK, p16 upregulation, CDK-inactivation causing cervical
cancer, role of VEGF, role of estrogen and its receptor in cervical cancer.
Results:
Cervical cancer can be screened by Pep test. There are various therapies that can be used
to treat cervical cancer. As these therapies have various side effects, so the world is moving to
herbal formulations to treat cervical cancer.
Conclusion:
In this study, we will discuss cervical cancer, its cause, symptoms, pathophysiology
and treatments. Early screening and detection can help in reducing the overall burden of cervical
cancer in the near future.

Abstract
Essential oil of eucalyptus species is among the most common traded essential oils in the world. There is an increasing interest in the application of eucalyptus oil as a natural additive in food and pharmaceutical industry. The present study was undertaken to identify the phytoconstituents present in the essential oil of Eucalyptus globulus leaves (EO) and ascertain their protective effect against ketamine-induced psychosis in rats. GC-MS technique was used for analysis of phytoconstituents present in EO. Ketamine (50 mg/kg, i.p.) was used to induce psychosis in rats. Photoactometer, forced swim test and pole climb avoidance test were used to evaluate the protective effects of the EO (500, 1000 and 2000 mg/kg, p.o.) on acute and chronic administration. Bar test was used to test the side effect of EO. Biochemical and neurochemical estimations were carried out to explore the possible mechanism of action. GC-MS analysis of EO showed the presence of a number of biologically active compounds. EO at the dose of 500, 1000 and 2000 mg/kg, p.o. on acute and chronic administration, decreased locomotor activity, immobility duration and latency to climb the pole. EO was effective to facilitate the release of GABA, increase GSH levels, inhibit dopamine neurotransmission and decrease TNF-α levels as well as diminish AChE activity in different regions of the brain. EO at the dose of 500, 1000 mg/kg did not produce cataleptic behavior in rats. EO at the dose of 500, 1000 mg/kg produced protective effects against ketamine-induced psychosis and can be further explored clinically against neuropsychiatric disorders.

Abstract
The periodontal complex is essential for tooth attachment and function and includes the mineralized tissues, cementum and alveolar bone, separated by the unmineralized periodontal ligament (PDL). To gain insights into factors regulating cementum-PDL and bone-PDL borders and protecting against ectopic calcification within the PDL, we employed a proteomic approach to analyze PDL tissue from progressive ankylosis knock-out (Ank-/-) mice, featuring reduced PPi, rapid cementogenesis, and excessive acellular cementum. Using this approach, we identified the matrix protein osteopontin (Spp1/OPN) as an elevated factor of interest in Ank-/- mouse molar PDL. We studied the role of OPN in dental and periodontal development and function. During tooth development in wild-type (WT) mice, Spp1 mRNA was transiently expressed by cementoblasts and strongly by alveolar bone osteoblasts. Developmental analysis from 14 to 240days postnatal (dpn) indicated normal histological structures in Spp1-/- comparable to WT control mice. Microcomputed tomography (micro-CT) analysis at 30 and 90dpn revealed significantly increased volumes and tissue mineral densities of Spp1-/- mouse dentin and alveolar bone, while pulp and PDL volumes were decreased and tissue densities were increased. However, acellular cementum growth was unaltered in Spp1-/- mice. Quantitative PCR of periodontal-derived mRNA failed to identify potential local compensators influencing cementum in Spp1-/- vs. WT mice at 26dpn. We genetically deleted Spp1 on the Ank-/- mouse background to determine whether increased Spp1/OPN was regulating periodontal tissues when the PDL space is challenged by hypercementosis in Ank-/- mice. Ank-/-; Spp1-/- double deficient mice did not exhibit greater hypercementosis than that in Ank-/- mice. Based on these data, we conclude that OPN has a non-redundant role regulating formation and mineralization of dentin and bone, influences tissue properties of PDL and pulp, but does not control acellular cementum apposition. These findings may inform therapies targeted at controlling soft tissue calcification.

Abstract
BACKGROUND Stigmasterol, a naturally occurring phytoestrogen has been reported to possess many pharmacological activities. The aim of the present study was to screen the effect of stigmasterol against ketamine-induced mice model of psychosis. METHODS The behavioural studies included an assessment of locomotor activity, stereotypic behaviours, immobility duration, step down latency and effects on catalepsy. Biochemical estimations involved the estimations of GABA, dopamine, GSH, MDA, TNF-α, total protein content and AChE activity. Histopathological changes and effect on androgenic parameters were also evaluated. RESULTS Stigmasterol treated animals showed significant decrease in locomotor activity, stereotypic behaviours, immobility duration and increased step down latency. Biochemical estimations revealed increased GABA, GSH levels and decreased dopamine, MDA, TNF-α levels and AChE activity. These findings were confirmed by histopathological changes in the cortex part of the brain. Further, stigmasterol was not found to cause catalepsy and any adverse effect on the reproductive system. CONCLUSION This study concluded that stigmasterol could ameliorate ketamine-induced behavioral, biochemical and histopathological alterations in mice showing its potential effects in the management of psychotic symptoms.

Abstract
Trichomonas vaginalis (T. vaginalis) infection leads to the synthesis of specific antibodies in the serum and local secretions. The profile of T. vaginalis-specific antibodies and T cell-mediated immune responses may influence the outcome of infection, towards parasite elimination, persistence or pathological reactions. Studies have indicated that Th1-, Th17- and Th22 cell-related cytokines may be protective or pathogenic, whereas Th2- and Treg cell-related cytokines can exert anti-inflammatory effects during T. vaginalis infection. A number of T. vaginalis-related components such as lipophosphoglycan (TvLPG), α-actinin, migration inhibitory factor (TvMIF), pyruvate:ferredoxin oxidoreductase (PFO), legumain-1 (TvLEGU-1), adhesins and cysteine proteases lead to the induction of specific antibodies. T. vaginalis has acquired several strategies to evade the humoral immune responses such as degradation of immunoglobulins by cysteine proteases, antigenic variation and killing of antibody-producing B cells. The characterization of the T. vaginalis-specific antibodies to significant immunogenic molecules and formulation of strategies to promote their induction in vaginal mucosa may reveal their potential protective effects against trichomoniasis. In this review, we discuss the current understanding of antibody and T cell-mediated immune responses to T. vaginalis and highlight novel insights into the possible role of immune responses in protection against parasite.

Abstract
To develop statistically optimized brain targeted Tween 80 coated chitosan nanoparticulate formulation for oral delivery of doxycycline hydrochloride for the treatment of psychosis and to evaluate its protective effect on ketamine induced behavioral, biochemical, neurochemical and histological alterations in mice. 32 full factorial design was used to optimize the nanoparticulate formulation to minimize particle size and maximize entrapment efficiency, while independent variables chosen were concentration of chitosan and Tween 80. The optimized formulation was characterized by particle size, drug entrapment efficiency, Fourier transform infrared, Transmission electron microscopy analysis and drug release behavior. Pure doxycycline hydrochloride (25 and 50 mg/kg, p.o.) and optimized doxycycline hydrochloride encapsulated Tween 80 coated chitosan nanoparticles (DCNPopt) (equivalent to 25 mg/kg doxycycline hydrochloride, p.o.) were explored against ketamine induced psychosis in mice. The experimental studies for DCNPopt, with mean particle size 237 nm and entrapment efficiency 78.16%, elucidated that the formulation successfully passed through blood brain barrier and exhibited significant antipsychotic activity. The underlying mechanism of action was further confirmed by behavioral, biochemical, neurochemical estimations and histopathological study. Significantly enhanced GABA and GSH level and diminished MDA, TNF-α and dopamine levels were observed after administration of DCNPopt at just half the dose of pure doxycycline hydrochloride, showing better penetration of doxycyline hydrochloride in the form of Tween 80 coated nanoparticles through blood brain barrier. This study demonstrates the hydrophilic drug doxycycline hydrochloride, loaded in Tween 80 coated chitosan nanoparticles, can be effectively brain targeted through oral delivery and therefore represents a suitable approach for the treatment of psychotic symptoms.

Abstract
Gallic acid has been reported to possess a number of psychopharmacological activities. These activities are attributed to the antioxidant potential due to the presence of phenolic moeity. The present study was carried out to investigate the protective effects of gallic acid in an experimental model of ketamine-induced psychosis in mice. Ketamine (50 mg/kg, i.p.) was used to induce stereotyped psychotic behavioural symptoms in mice. Behavioural studies (locomotor activity, stereotype behaviour, immobility duration and memory retention) were carried out to investigate the protective of gallic acid on ketamine-induced psychotic symptoms, followed by biochemical and neurochemical changes and cellular alterations in the brain. Chronic treatment with gallic acid for 15 consecutive days significantly attenuated stereotyped behavioural symptoms in mice. Biochemical estimations revealed that gallic acid reduced the lipid peroxidation and restored the total brain proteins. Furthermore, gallic acid remarkably reduced the dopamine levels, AChE activity and inflammatory surge (serum TNF-α), and increased the levels of GABA and increased glutathione in mice. The study revealed that gallic acid could ameliorate psychotic symptoms and biochemical changes in mice, indicating protective effects in psychosis.

Abstract
BACKGROUND In clinical practice, the restoration of non-carious cervical lesions is a challenge, because most of the time the cervical margin is located in cementum or dentin. This characteristic makes the cervical margin more susceptible to microleakage, causing cavosurface stains, postoperative sensitivity and also favours the incidence of carious lesions. AIM To compare and evaluate the microleakage in class V lesions restored with Activa Bioactive restorative and nanohybrid composite resin using two different bonding agents. METHODOLOGY In this study, 50 class V cavities were prepared in freshly extracted teeth. The samples were randomly divided into 5 groups (n=10), depending on the type of restorative material and bonding agent: Group 1 - Activa Bioactive (Pulpdent, USA) + No bonding, Group 2 - Activa Bioactive + Tetric N Bond (Ivoclar Vivadent, Colombia),Group 3 - Activa Bioactive + G Bond (GC Corp., Tokyo, Japan), Group 4 - Nanohybrid Composite (Ivoclar Vivadent, Colombia) + Tetric N Bond, Group 5 - Nanohybrid Composite + G Bond. The samples were restored with their respective material based on the group. After curing all the specimens were subjected to thermocycling and cyclic loading. Specimens were stained with 2% rhodamin b dye and evaluated for dye penetration. RESULTS Results were obtained based on Kruskal Wallis and Mann Whitney U- test. CONCLUSION Within the limitations of this study, none of the materials were free from microleakage. All the materials showed more microleakage at gingival margins compared to occlusal margins. Among all the groups Activa Bioactive restorative when used in combination with Tetric N Bond showed the least microleakage.

Abstract
Background: A major change in anesthesia practice as regards to intraoperative infusion therapy is the present requirement. Switching over to balanced fluids can substantially decrease the incidence of lactic acidosis and hyperchloremic acidosis. The deleterious effects of unbalanced fluids are more recognizable during major surgeries. We prospectively studied the influence of Sterofundin (SF) and Ringer lactate (RL) on acid–base changes, hemodynamics, and readiness for extubation during scoliosis surgery. Subjects and Methods: Thirty consecutive children posted for scoliosis surgery were randomized to receive either RL (n = 15) or SF (n = 15) as intraoperative fluid at 10 mg/kg/h. Fluid boluses were added according to the study fluid algorithm. Arterial blood was sampled and analyzed at hourly intervals during surgery. Red blood cell transfusion was guided by hematocrit below 27. Patients were followed for 24 h postoperatively in the Intensive Care Unit. Results: There was no statistically significant difference in the volume of infused fluid (2400 ± 512 ml in Group RL and 2200 ± 640 ml in Group SF. There were no significant changes in pH of patients infused with SF. Statistically, significant higher lactate levels were seen in RL-infused group. The strong ion difference was decreased in both groups, but it normalized earlier with SF. Conclusions: SF-infused patients had nonremarkable changes in acid–base physiology in scoliosis surgery.

Abstract
Escherichia vulneris is an opportunistic human pathogen. It has been primarily reported in adult patients and invasive infections have been observed in immune-suppressed individuals. This is the first report of E. vulneris causing complicated diarrhoea and sepsis in an infant. Two month old sick infant, born full-term, was admitted to the paediatrics department with loose motions and refusal to feed for four days. E. vulneris was isolated from blood in pure culture. The isolate was characterized for diarrhoeal virulence markers: heat labile and heat stable toxins (LT, ST) and hemolysin (hlyA) by PCR. The presence of LT enterotoxin and hemolysin provides strong evidence of the diarrhoeagenic potential of E. vulneris, further leading to the invasive infection triggering sepsis. As E. vulneris can lead to serious complications, an attempt should be made in clinical laboratories to identify and further characterize this new Escherichia species.

Abstract
Background and Aims: Postoperative sore throat (POST) is a well-recognized complication after general anesthesia (GA). Numerous nonpharmacological and pharmacological measures have been used for attenuating POST with variable success. The present study was conducted to compare the efficiency of preoperative nebulization of normal saline and magnesium sulfate in reducing the incidence of POST following GA. Materials and Methods: Following institutional ethical committee approval and written informed consent, a prospective randomized double-blinded study was conducted in 100 cases divided into two equal groups. Patients included in the study were of either gender belonging to American Society of Anesthesiologist (ASA) status 1 or 2 undergoing elective surgery of approximately 2 h or more duration requiring tracheal intubation. Patients in Group A are nebulized with 3 ml of normal saline and the patients in Group B are nebulized with 3 ml of 225 mg isotonic nebulized magnesium sulfate for 15 min, 5 min before induction of anesthesia. The incidence of POST at rest and on swallowing and any undue complaints at 0, 2, 4, and 24 h in the postoperative period are evaluated. Results: There is no significant difference in POST at rest during 0th, 2nd and 4th h between normal saline and MgSO4. Significant difference is seen at 24th h, where MgSO4 lessens POST. There is no significant difference in POST on swallowing during 0th and 2nd h between normal saline and MgSO4. Significant difference is seen at 4th h, where MgSO4 has been shown to lessen POST. Conclusions: MgSO4 significantly reduces the incidence of POST compared to normal saline.
