PREVENTION OF PEPTIC ULCERS BY CURCUMIN IN CHEMICALLY INDUCED OSTEOARTHRITIS

Objective: The present study was carried out to investigate the role of curcumin in osteoarthritis when it is used as an adjuvant to diclofenac sodium.Methods: Osteoarthritis (OA) was induced by administering nalidixic acid 400 mg/kg. Animals (Female rats) were divided into 5 groups each containing 6 animals. Group I was considered as control, group II in which the animals were induced with osteoarthritis with nalidixic acid and were given no treatment. Group III in which osteoarthritis induced animals were treated with diclofenac sodium by the oral route. Group IV osteoarthritis induced animals were treated with the combination of diclofenac sodium and curcumin and group V animals were pre-treated with curcumin and then induced with osteoarthritis. Parameters like ulcer area, ulcer index, free acidity, total acidity, the volume of gastric juice were estimated. Histopathological studies were also carried out.Results: The data of our study shows that nalidixic acid has not shown much effect on the gastric parameters in group II animals. The ulcer index, free acidity, total acidity and gastric juice volume were increased significantly (p<0.001) in group III and decreased in group IV animals (p<0.05) when compared to group I control animals. Group V animals pretreated with curcumin have shown fewer incidences of gastric ulcers and other ulcerative parameters non significantly. Histopathology also suggests a low incidence of ulcers in group IV and group V.Conclusion: It demonstrates that curcumin when used along with the conventional NSAIDs as an adjuvant therapy, has a role in treating osteoarthritis effectively

Robust foreground modelling to segment and detect multiple moving objects in videos

Last decade has witnessed an ever increasing number of video surveillance installations due to the rise of security concerns worldwide. With this comes the need for video analysis for fraud detection, crime investigation, traffic monitoring to name a few. For any kind of video analysis application, detection of moving objects in videos is a fundamental step. In this paper, an efficient foreground modelling method to segment multiple moving objects is implemented. Proposed method significantly reduces noise thereby accurately segmenting region of interest under dynamic conditions while handling occlusion to a large extent. Extensive performance analysis shows that the proposed method was found to give far better results when compared to the de facto standard as well as relatively new approaches used for moving object detection

PERFOGRAPH: A Numerical Aware Program Graph Representation for Performance Optimization and Program Analysis

The remarkable growth and significant success of machine learning have expanded its applications into programming languages and program analysis. However, a key challenge in adopting the latest machine learning methods is the representation of programming languages, which directly impacts the ability of machine learning methods to reason about programs. The absence of numerical awareness, composite data structure information, and improper way of presenting variables in previous representation works have limited their performances. To overcome the limitations and challenges of current program representations, we propose a novel graph-based program representation called PERFOGRAPH. PERFOGRAPH can capture numerical information and the composite data structure by introducing new nodes and edges. Furthermore, we propose an adapted embedding method to incorporate numerical awareness. These enhancements make PERFOGRAPH a highly flexible and scalable representation that can effectively capture program intricate dependencies and semantics. Consequently, it serves as a powerful tool for various applications such as program analysis, performance optimization, and parallelism discovery. Our experimental results demonstrate that PERFOGRAPH outperforms existing representations and sets new state-of-the-art results by reducing the error rate by 7.4% (AMD dataset) and 10% (NVIDIA dataset) in the well-known Device Mapping challenge. It also sets new state-of-the-art results in various performance optimization tasks like Parallelism Discovery and Numa and Prefetchers Configuration prediction

Transcription of human resistin gene involves an interaction of Sp1 with peroxisome proliferator-activating receptor gamma (PPARγ)

Background: Resistin is a cysteine rich protein, mainly expressed and secreted by circulating human mononuclear cells. While several factors responsible for transcription of mouse resistin gene have been identified, not much is known about the factors responsible for the differential expression of human resistin. Methodology/Principal Finding: We show that the minimal promoter of human resistin lies within ~80 bp sequence upstream of the transcriptional start site (-240) whereas binding sites for cRel, CCAAT enhancer binding protein α (C/EBP-α), activating transcription factor 2 (ATF-2) and activator protein 1 (AP-1) transcription factors, important for induced expression, are present within sequences up to -619. Specificity Protein 1(Sp1) binding site (-276 to -295) is also present and an interaction of Sp1 with peroxisome proliferator activating receptor gamma (PPARγ) is necessary for constitutive expression in U937 cells. Indeed co-immunoprecipitation assay demonstrated a direct physical interaction of Sp1 with PPARγ in whole cell extracts of U937 cells. Phorbol myristate acetate (PMA) upregulated the expression of resistin mRNA in U937 cells by increasing the recruitment of Sp1, ATF-2 and PPARγ on the resistin gene promoter. Furthermore, PMA stimulation of U937 cells resulted in the disruption of Sp1 and PPARγ interaction. Chromatin immunoprecipitation (ChIP) assay confirmed the recruitment of transcription factors phospho ATF-2, Sp1, Sp3, PPARγ, chromatin modifier histone deacetylase 1 (HDAC1) and the acetylated form of histone H3 but not cRel, C/EBP-α and phospho c-Jun during resistin gene transcription. Conclusion: Our findings suggest a complex interplay of Sp1 and PPARγ along with other transcription factors that drives the expression of resistin in human monocytic U937 cells

Antigen Presenting Cells Contribute to Persistent Immune Activation Despite Antiretroviral Therapy Initiation During Hyperacute HIV-1 Infection

Human immunodeficiency virus (HIV)-induced changes in immune cells during the acute phase of infection can cause irreversible immunological damage and predict the rate of disease progression. Antiretroviral therapy (ART) remains the most effective strategy for successful immune restoration in immunocompromised people living with HIV and the earlier ART is initiated after infection, the better the long-term clinical outcomes. Here we explored the effect of ART on peripheral antigen presenting cell (APC) phenotype and function in women with HIV-1 subtype C infection who initiated ART in the hyperacute phase (before peak viremia) or during chronic infection. Peripheral blood mononuclear cells obtained longitudinally from study participants were used for immunophenotyping and functional analysis of monocytes and dendritic cells (DCs) using multiparametric flow cytometry and matched plasma was used for measurement of inflammatory markers IL-6 and soluble CD14 (sCD14) by enzyme-linked immunosorbent assay. HIV infection was associated with expansion of monocyte and plasmacytoid DC (pDC) frequencies and perturbation of monocyte subsets compared to uninfected persons despite antiretroviral treatment during hyperacute infection. Expression of activation marker CD69 on monocytes and pDCs in early treated HIV was similar to uninfected individuals. However, despite early ART, HIV infection was associated with elevation of plasma IL-6 and sCD14 levels which correlated with monocyte activation. Furthermore, HIV infection with or without early ART was associated with downmodulation of the co-stimulatory molecule CD86. Notably, early ART was associated with preserved toll-like receptor (TLR)-induced IFN-α responses of pDCs. Overall, this data provides evidence of the beneficial impact of ART initiated in hyperacute infection in preservation of APC functional cytokine production activity; but also highlights persistent inflammation facilitated by monocyte activation even after prolonged viral suppression and suggests the need for therapeutic interventions that target residual immune activation

Acarbose versus orlistat in weight management of infertile women with polycystic ovarian syndrome: a prospective randomized controlled trial

Background: Polycystic Ovarian Syndrome (PCOS) affects about 4 to 12% of women worldwide. PCOS is the most common cause of anavulation in infertile women. The endocrine dysfunction of PCOS is aggravated by obesity. Weight management is the first line treatment of this condition. In this study, we tried to compare acarbose versus orlistat in weight management of infertile women with polycystic ovarian syndrome. The aim of this study was to compare the effects of acarbose and orlistat in weight management of infertile polycystic ovarian syndrome women.Methods: This open label randomized controlled trial study was conducted in the Department of Reproductive Endocrinology and Infertility, BSMMU, Dhaka, Bangladesh. The study period was 1 year from July 2019 to June 2020. A total of 32 obese infertile women with PCOS were included in the study and randomized to two treatment arms: acarbose 100 mg tds for 3 months and orlistat 120 mg tds for 3-months.Results: The response of adequate (>10%) weight reduction with acarbose was 67% of that with orlistat. The side effects with acarbose were 15% of that with orlistat. Acanthosis nigricans was reduced in 18.8% (n=3/16) of those receiving acarbose.Menstrual cycle regularized in 37.5% (n=6/16) in experimental (acarbose) group and in 18.8% (n=3/16) in control (orlistat) group.Conclusions: The therapeutic potential of acarbose in reducing weight was relatively less than orlistat in obese infertile PCOS women

BOTOX! BETTER OPTION TO PROTECT CORNEA IN IDIOPATHIC BELL’S PALSY

Aim: Is to evaluate the efficacy of Chemo-denervation of LPS to induce temporary ptosis using Injection Botox in protecting Cornea and healing exposure keratopathy. Materials & Methods: Prospective interventional study conducted at Tertiary eye care centre of Hyderabad. Study period between June 2010 to May 2012. 24 cases of Bell’s palsy , 11 males & 14 females between age group of 20-80 years were included in the study. Facial palsy due to CP angle tumors, Hansen’s disease, Trauma, CSOM and post mastoidectomy were excluded as these are permanent causes. Patient with known allergy to Botox and patient who lost to follow up were also excluded. Cases included were examined by an ophthalmologist and radiologically evaluated to rule out other causes of facial palsy. Height of palpebral aperture, amount of Lagophthalmos, exposure keratopathy was documented. 0.25cc of injection Botox containing 6.25IU of Botox was injected at the insertion of LPS. Patient was examined at the end of 1st week, 2nd week, 4th week and 8th week to check all the 3 parameters. Results: At the end of 1st week in 16 cases mean palpebral height of 9mm (SD +/- 1.2mm) before injection was reduced to 2mm (SD+/- 1.0mm) after injection. At the end of 2nd week 8 cases achieved ptosis. Mean difference in Palpebral aperture height was 7mm (p value of 0.05) which is significant. All cases showed improvement in exposure keratopathy. 20 cases recovered from Bell’s palsy within 8 weeks . 4 cases required 2nd injection of Botox as ptosis started recovering but Bell’s palsy persists. Mean amount of Lagophthalmos of 4.3mm (SD+/- 0.7mm) before injection was reduced to 1.1mm (SD+/- 1.0mm) at the end of 2nd week. P value of <0.05 which is significant. Conclusion: Inj.Botox is safe and effective method to achieve ptosis by Chemo-denervation of LPS. Action of Botox remains for 8 weeks wherein 85% of cases recovered from Bell’s palsy

Effect of aromatase inhibitor, letrozole on semen parameters in eugonadotropic hypoandrogenic men with oligozoospermia

Background: Some men with severely defective sperm production commonly have excess aromatase activity, reflected by low serum testosterone and relatively elevated estradiol levels. Elevated levels of estrogen lead to feedback inhibition of the hypothalamic -pituitary-gonadal axis, and the end result is a decrease in LH necessary for the production of testosterone, and FSH to optimize sperm production. The aim of this study was to evaluate the effect of aromatase inhibitor, letrozole on the semen parameters of infertile male having oligozoospermia, low serum testosterone level and testosterone to estradiol ratio <10.Methods: This Prospective study was conducted in the Department of Reproductive Endocrinology and Infertility at Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh during the period from May 2019 to April 2020. The sample size was 30 subfertile men with oligozoospermia (≤ 10 million/ml), low serum testosterone level (<300 ng/dl) and low testosterone to estradiol ratio (<10). All patients were treated with letrozole 2.5 mg daily for 4 months. At the end of the 4 months the semen analysis was performed. Statistical analysis was carried out by using IBM Statistical Package for Social Sciences version 25 for windows (SPSS version 25.0).Results: The sperm concentration, sperm motility and total motile sperm count significantly increased after letrozole treatment. The side effects were mild and well tolerated.Conclusions: This study suggests that some men with oligozoospermia, low serum testosterone levels and normal gonadotropin concentration may have a treatable endocrinopathy. Letrozole may be used to improve sperm parameters in infertile men with low serum testosterone to estradiol ratio
