RESUMO Contexto: O papel dos níveis ascíticos e séricos de vários biomarcadores de tumores na discriminação da causa das ascites não está bem estabelecido. Objetivo: Avaliar o papel dos níveis séricos e ascíticos de biomarcadores tumorais (CA 72-4, CA 19-9, CEA e CA 125) na discriminação da causa das ascites. Métodos: Estudo prospectivo foi realizado em pacientes consecutivos que apresentaram ascite. Foram determinados níveis do soro e ascítico de CA 19-9, CA 125, CA 72-4 e antígeno carcinoembrínico (CEA). Os pacientes com ascites cirróticas, peritonite tuberculosa e carcinomatose peritoneal (CP) foram eventualmente incluídos na análise. Resultados: Dos 93 pacientes (58 homens, média de idade 47 anos) incluídos, a causa básica foi cirrose em 31, CP em 42 e tuberculose peritoneal em 20. O melhor corte para discriminação de ascites benignas e malignas para soro CEA, CA 19-9 e CA 72-4 foram 6,7 ng/mL, 108 UI/mL e 8,9 UI/mL, respectivamente. O melhor corte para discriminação de ascites benignas e malignas para CA 125 ascitico, CEA, CA 19-9 e CA 72-4 foram 623 UI/mL, 8,7 ng/mL, 33,2 UI/mL e 7 UI/mL, respectivamente. Conclusão: O desempenho do biomarcador único para a previsão do CP subjacente é baixo, mas uma combinação de soro CA 19-9 e CA 72-4 melhor previu a presença de carcinomatose peritoneal.

ABSTRACT Background: The role of ascitic and serum levels of various tumour biomarkers in the discrimination of cause of ascites is not well established. Objective: To evaluate the role of serum and ascitic levels of tumor biomarkers (CA 72-4, CA 19-9, CEA and CA 125) in discrimination of cause of ascites. Methods: A prospective study was conducted in consecutive patients presenting with ascites. Serum and ascitic levels of CA 19-9, CA 125, CA 72-4 and carcinoembryonic antigen (CEA) were determined at the presentation. The patients with cirrhotic ascites, tuberculous peritonitis (TBP) and peritoneal carcinomatosis (PC) were eventually included in analysis. Results: Of the 93 patients (58 males, mean age 47 years) included, the underlying cause was cirrhosis in 31, PC in 42 and peritoneal tuberculosis in 20. The best cutoff for discriminating benign and malignant ascites for serum CEA, CA 19-9 and CA 72-4 were 6.7 ng/mL, 108 IU/mL and 8.9 IU/mL, respectively. The best cutoff for discriminating benign and malignant ascites for ascitic CA 125, CEA, CA 19-9 and CA 72-4 were 623 IU/mL, 8.7 ng/mL, 33.2 IU/mL and 7 IU/mL, respectively. Conclusion: The performance of single biomarker for the prediction of underlying PC is low but a combination of serum CA 19-9 and CA 72-4 best predicted the presence of peritoneal carcinomatosis.

Abstract Periodontitis is an oral disease associated with inflammation and pain with swollen and bleeding gums. In the present study, dental pastes containing NSAIDs, namely, diclofenac sodium and nimesulide (1 % w/w) were prepared to treat periodontitis. Dental pastes of diclofenac sodium and nimesulide (1 % w/w) were prepared with/without mucoadhesive hydrocolloid polymers such as sodium carboxy methyl cellulose (NaCMC), hydroxyl ethyl cellulose (HEC) and methyl cellulose (MC) by conventional trituration method. The pH, drug content, viscosity, tube spreadability and tube extrudability of these prepared dental pastes were measured. These dental pastes of diclofenac sodium and nimesulide (1 % w/w) were characterized by FTIR analyses for drug-excipient compatibility. The in vitro drug releases from these dental pastes in 6.4 pH phosphate buffer solution displayed sustained release over longer period and the drug release rate was found to be decreased when the concentration of mucoadhesive polymer was increased. These dental pastes displayed good adhesion to the oral mucosa revealing more retention time in mouth when tested for ex vivo mucoadhesion using bovine cheek pouch. The stability study results reveal that the DC3 and NC3 dental paste formulations were found stable enough over a longer period in different storage conditions. The present study revealed that the prepared mucoadhesive dental pastes of diclofenac sodium and nimesulide (1 % w/w) had good adhesion with the oral mucosa to maintain consistent release of drugs over prolonged time.

Abstract Ischemic postconditioning (IPTC) brings cardioprotection endogenously, Atrial natriuretic peptide (ANP) produces the same effect. It happens due to down expression of endothelial nitric oxide synthase (eNOS). Thus, experimental protocol associating IPTC has been formulated to find the role of ANP in the cardioprotection of heart in OVX rats. For this experiment, heart was isolated from OVX rat and held tightly on Langendorff’s apparatus in a manner that ischemia of 30 min and reperfusion of 120 min were also given. Simultaneously, IPTC with four cycles of 5 min ischemia and 5 min reperfusion of each was applied. Parameters like size of myocardial infarct, levels of lactate dehydrogenase (LDH) and release of creatine kinase- MB (CK-MB) in coronary effluent were noted after each stage of experiment for ensuring the extent of myocardial injury. Some significant changes were also seen in the histopathology of cardiovascular tissues. The cardio-protection has been made by four cycles of IPTC. It was confirmed by decline in the size of myocardial infarct. It diminishes the release of LDH and CK-MB in heart of OVX rat. Thus, IPTC induces cardio-protection in the isolated heart from OVX rat. Perfusion of ANP associating with IPTC favors the cardioprotection which is further confirmed by rise in the NO release and heart rate. The level of myocardial damage changes using IPTC, IPTC+OVX, IPTC+OVX+ANP, IPTC+ OVX+ANP+L-NAME and other groups were observed significantly and were found to be less than those in I/R control group. Thus, it is recommended that ANP involving IPTC restores attenuated cardio-protection in OVX rat heart. Therefore, Post-conditioning is useful in various clinical aspects.

ABSTRACT Objective: To summarize current trends in the pathogenesis and management of disc degeneration and suggest areas where more research would be of benefit. Methods: The available literature relevant to Lumbar disc degeneration (LDD) was reviewed. PubMed, MEDLINE, OVID, EMBASE, Cochrane, and Google Scholar databases were used to review the literature. Institutional Review Board approval was not applicable for this study. Results: This article summarizes trends in the pathogenesis and factors associated with disc degeneration. Conclusions: The genetic contribution to lumbar disc degeneration is a newer concept, still being researched in different populations around the world. Investigators have demonstrated a familial predisposition in the etiology of lumbar disc degeneration. The effect sizes of most genetic variants are small and, thus, individual gene-environment studies must have very large sample sizes to provide compelling evidence of any interaction. Level of evidence; Narrative review of available literature.

Abstract Objective: To quantify and compare respiratory functions and further screen the oral mucosa of tobacco and non-tobacco users. Material and Methods: First control group, non-tobacco users (n=55); Second group, smokers’ group (n=168) who currently smoked cigarettes; Third group smokeless/chewing type, tobacco group (n=81); Fourth group, both smokeless and smoking type tobacco users (n=46). Fagerstrom Test for Nicotine Dependences (FTND) and Fagerström Test for Nicotine Dependence-Smokeless Tobacco (FTND-ST) instruments were used to assess nicotine dependence. Subsequently, spirometry and Toluidine Blue (TB) vital staining were performed. Chi-squared and one-way analysis of variance (ANOVA) were used for statistical analysis. Results: Fagerstrom test resulted in 48.8% of subjects with low dependency, followed by an increase in nicotine dependency from low to moderate (29.2%), moderate (15.6%), and highly dependent (6.4%) groups. All respiratory function tests and oral screening confirmed significant changes amongst tobacco and non-tobacco users. The forced vital capacity of non-smoker group was significantly different from other tobacco users’ group (p<0.05). Conclusion: Early effects of tobacco use can lead to complications with the respiratory system and oral cavity. Such data can be used to delineate the harm of tobacco and should be used to urge individuals to evade the utilization of tobacco.

Abstract In the current scenario while everything seems digitalized, we often spend more time scrolling across various social platforms as compared to what we spend in any other real life activities. It becomes a matter of great concern when it comes to analyze what we see and how it is interpreted. Through this paper we aims to identify the influence of technology assisted social-reform initiatives on gender-based hate content generation. With the help of Twitter API, 112577 government-initiated and 58370 citizen-initiated movement(s) tweets have been extracted. This collected data is examined for hatred nature content in terms of emotions using a software programmed in R programming language, the scores for each emotion is counted and a comparison between both the moments is made. The study clearly shows that the Citizen-initiated moments shares comparatively more hate content than the Government-initiated movements as the scores particular to specific emotions like anger, disgust, and sadness is more. This cognitive study can be helpful in policy making, promoting gender based equality, defining strategies to rebuild citizen initiatives in a hate-free environment and controlling hate content generation.

Agro-industrial wastes such as sugarcane bagasse, wheat bran, rice bran, corn cob and wheat straw are cheapest and abundantly available natural carbon sources. The present study was aimed to production of amylase and xylanase simultaneously using agro-industrial waste as the sole carbon source. Seven thermophilic strains of actinomycete were isolated from the mushroom compost. Among of these, strain designated MSC702 having high potential to utilize agro-industrial wastes for the production of amylase and xylanase. Strain MSC702 was identified as novel species of Streptomyces through morphological characterization and 16S rRNA gene sequence. Enzyme production was determined using 1% (w/v) of various agro-industrial waste in production medium containing (g/100mL): K2HPO4(0.1), (NH4)2SO4(0.1), NaCl (0.1), MgSO4(0.1) at pH 7.0 after incubation of 48 h at 50°C. The amylase activity (373.89 IU/mL) and xylanase activity (30.15 IU/mL) was maximum in rice bran. The decreasing order of amylase and xylanase activity in different type of agro-industrial wastes were found rice bran (RB) > corn cob (CC) > wheat bran (WB) > wheat straw (WS) > sugarcane bagasse (SB) and rice bran (RB) > wheat bran (WB) > wheat straw (WS) > sugarcane bagasse (SB) > corn cob (CC), respectively. Mixed effect of different agro-industrial wastes was examined in different ratios. Enzyme yield of amylase and xylanase was ~1.3 and ~2.0 fold higher with RB: WB in 1:2 ratio.

Variações arteriais no triângulo femoral têm sido pouco relatadas na literatura. No presente artigo, relatou-se um caso de origem alta da artéria femoral profunda, que estava se originando pouco abaixo do ligamento inguinal. Também foi observado que a artéria femoral circunflexa originava-se diretamente da artéria femoral, ao invés de ser originada da artéria femoral profunda. Discutiu-se sobre anatomia, base embriológica e implicações clínicas dessas variações junto com uma revisão da literatura pertinente. A importância do conhecimento sobre essas variações no quadro das intervenções diagnósticas e terapêuticas é discutida.

Arterial variations of the femoral triangle are rarely reported in the literature. In the present article, we have reported a case of high origin of the deep femoral artery, which was originating just lower to the inguinal ligament. It was also observed that the lateral circumflex femoral artery arose directly from the femoral artery instead from the deep femoral artery. We have discussed the anatomy, embryological basis, and clinical implications of these variations along with relevant literature review. The importance of knowledge about these variations in therapeutic and diagnostic interventions is discussed.

The morphometrical data related to the menisci of the adults have been reported by few authors and that of the fetuses have not been reported. The aims of the present study were to analyse the external circumference thickness, the width, peripheral and inner border lengths, and the distance between anterior and posterior horns of the fetal menisci and to compare the meniscal dimensions with that of the adult meniscal parameters which are available in the literature. The menisci from 106 knee joints of the formalin fixed South Indian fetuses which were obtained from the anatomy department were analysed. The fetuses which had musculoskeletal anomalies were excluded from the study. A vernier caliper of 0.02 mm accuracy and a non elastic cotton thread were used for the morphometry. After comparing the meniscal dimensions of the present study with the adult meniscus parameters, we established that the fetal parameters of the meniscus are entirely different from the adults. These differences are may be due to the mesenchymal differentiation or variability of the vasculature early in embryonic life. We believe that our study will provide support to the fetal anatomy, concerning surgical procedures and arthroscopy of the knee joint. Since the morphometric studies of the fetal menisci are not reported, this study may be considered new and needs to be studied further with different groups of fetuses from various stages of intrauterine development. This study is important not only for orthopedic surgeons, but also for morphologists and embryologists.

Los datos morfométricos relacionados con los meniscos de los adultos han sido reportados por algunos autores, mientras que en fetos éstos aún no han sido descritos. El objetivo del estudio fue analizar, en fetos, el grosor de la circunferencia externa, ancho, y longitud de los márgenes interno y externo, asi como la distancia entre los cuernos anteriores y posteriores. Además, comparar las dimensiones del menisco fetal con los parámetros de adultos disponibles en la literatura. Fueron analizados los meniscos de 106 articulaciones de rodillas fijadas en formalina, pertenecientes a fetos del sur de la India, obtenidos desde el Departamento de Anatomía. Los fetos con anomalías musculoesqueléticas fueron excluidos del estudio. Un pie de metro de 0,02 mm de precisión junto a hilo de algodón no elástico fueron utilizados para la morfometría. Después de comparar las dimensiones del menisco del presente estudio con los parámetros de meniscos adultos se estableció que los meniscos fetales son totalmente diferentes a los adultos. Estas diferencias pueden deberse a la diferenciación mesenquimal o la variabilidad de temprana vasculatura en la vida embrionaria. Creemos que nuestro estudio prestará apoyo a la anatomía fetal, en relación con los procedimientos quirúrgicos y la artroscopía de la rodilla. Los estudios morfométricos no han informado datos en meniscos fetales, por lo que esta investigación puede ser considerada novedosa y requiere seguir siendo estudiada con diferentes grupos de fetos en las diversas etapas del desarrollo intrauterino. Además el estudio de ser importante para los cirujanos ortopédicos, también lo es para morfólogos y embriólogos.
