A polyclonal antibody-based antigen-capture ELISA (AC-ELISA) has been developed for detection of Canine parvovirus (CPV) antigens in faecal samples of dogs. The assay uses rabbit anti-CPV polyclonal antibody as the capture antibody, guinea pig anti-CPV polyclonal antibody as tracing antibody and anti-guinea pig HRPO conjugate as the detection system. The optimum dilution of the capture antibody and the tracing antibody capable of detecting the CPV-2 antigens was found to be 1:1 600 and 1:400, respectively, in the check-board titration. In this study, a total of 152 samples (129 faecal samples and 23 cell culture supernatant) were tested both by AC-ELISA and by polymerase chain reaction (PCR). Of the samples tested, 69 and 78 samples were found positive by AC-ELISA and PCR, respectively. The AC-ELISA had relative sensitivity, relative specificity and accuracy of 88.4%, 100.0% and 91.4% respectively. The analytical sensitivity of AC-ELISA was estimated to be 102.8 TCID50/mL whereas PCR sensitivity was 100.8 TCID50/mL. The AC-ELISA is a simple, quick and reliable method for screening large numbers of faecal samples of dogs suspected of CPV infection.

Objective: Social Networking Sites (SNS) are gaining popularity across different cultures and age groups with its increasing role in the day-to-day life of its users. Objective of the present investigation is to study the SNS use and its relationship with online and real-life social capital, self-esteem and interpersonal relationships in normal and clinical population. Methods: The sample consisted of 93 participants of the age range 17-37 years, 63 participants from the general population and 30 from the clinical population with a diagnosis of any depressive or anxiety spectrum disorder. The tools used for this study are Basic Data Sheet, the Facebook Intensity Scale, Internet addiction Test, Internet Social Capital Scale. Results: The Rosenberg Self-Esteem Scale and Sentence Completion Test Results show that Facebook use has a positive correlation with online bonding and bridging capital. A significantly higher percentage of participants from the clinical group met the criteria for problem use of the Internet. Compared to average users, problem users of the Internet are found to have higher mean scores for online bridging capital and conflicts in inter-personal relationships and lower mean scores for real life bonding capital and self-esteem. Conclusions: It necessitates an exploration of Facebook's use patterns in routine evaluation and management of clinical conditions and implies the need for further research to develop explanatory models and management strategies for problematic use of the Internet.

To investigate two cyanobacteria isolated from different origins i.e. Lyngbya aestuarii(L. aestuarii) from brackish water and Aphanothece bullosa (A. bullosa) from fresh water paddy fields for antifungal and antileishmanila activity taking Candida albicans and Leishmaniadonovain as targets. Methods: Biomass of L. aestuarii and A. bullosa were harvested after 40 and 60 d respectively and lyophilized twice in methanol (100%) and redissolved in methanol (5%) for bioassay. Antifungal bioassay was done by agar well diffusion method while antileishmanial, by counting cell numbers and flageller motility observation of promastigotes and amastigotes fromL. donovani . Fluconazole and 5% methanol were used as control. Results: Both the cyanobacteria were found to be potent source of antifungal activity keeping fluconazole as positive control, however, methanolic crude extract (15 mg/mL) of A. bullosa was found more potent (larger inhibition zone) over that of methanolic crude extract of L. aestuarii. Similarly antileishmanial activity of crude extract (24.0 mg/mL) of A. bullosa was superior over that of methanolic crude extract of L. aestuarii (25.6 mg/mL). Conclusions: Antifungal and antileishmanial drugs are still limited in the market. Screening of microbes possessing antifungal and antileishmanial activity drug is of prime importance. Cyanobacteria are little explored in this context because most of the drugs in human therapy are derived from microorganisms, mainly bacterial, fungal and actinomycetes. Thus in the present study two cyanobacterial strains from different origins showed potent source of antifungal and antileishmanial biomolecules.

A rapid and sensitive ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was developed and validated for the estimation of 17-desacetyl norgestimate in human plasma using solid-phase extraction technique. 17-desacetyl norgestimate D6 was used as the internal standard. Simple gradient chromatographic conditions and mass spectrometric detection enabled accurate and precise measurement of 17-desacetyl norgestimate at sub-picogram levels. The proposed method was validated for a linear range of 20–5000 pg/mL with a correlation coefficient Z 0.9988. The intra-run and inter-run precision and accuracy were within 10%. The overall recoveries for 17-desacetyl norgestimate and 17-desacetyl norgestimate D6 were 96.30%and 93.90%, respectively. The total run time was 4.5 min. The developed method was applied for the determination of the pharmacokinetic parameters of 17-desacetyl norgestimate following a single oral administration of a norgestimate and ethinyl estradiol 0.250 mg/0.035 mg tablets in 35 healthy female volunteers.

Plants have been used as a source for food material and natural remedies for the treatment of vast range of diseases. Nature provides us remedies for the treatment of various types of disorders ranging from simple ailments to complicated diseases. Plants are known to possess different pharmacological activities due to the presence of various phytoconstituents. Flavonoids are one of the main active phytoconstituents found in fruits, vegetables, wines, tea and cocoa. Flavonoids exhibit various pharmacological activities such as antioxidant, anti-inflammatory, anti-allergic, antibacterial, oestrogenic, cytotoxic antitumoural, hepatoprotective, antithrombotic and antiviral activity. Diosmetin (3', 5, 7-trihydroxy-4'-methoxyflavone), the aglycone part of the flavonoid glycosides diosmin occurs naturally in citrus fruit. Although it is found in herbal medicines and plays an important role in the treatment of various ailments, only limited scientific researches have been conducted. The aim of this review is to collect all available scientific literature published on diosmetin and combine it into this paper. This review contains an overview of pharmacological activities, isolation techniques and analytical techniques for diosmetin. Thus, valuable information provided in the present review will help researchers in developing alternative methods for the treatment of diseases from diosmetin.

Background/Aims: Acute exacerbations of chronic hepatitis B (CHB-AEs) are common in endemic areas and are often presumed to be acute hepatitis B (AHB) due to their similarities in clinical and serological pictures, presenting a major diagnostic dilemma. This study aimed to identify laboratory markers for differentiating between the two groups, and to establish the cut-off value for significant markers. Methods: A retrospective analysis of records was conducted for patients who presented with clinical features of acute hepatitis along with hepatitis B surface antigen (HBsAg) and IgM antibody to hepatitis B core antigen (IgM anti-HBc) positivity from May 2015 to May 2017. A total of 172 patients were enrolled and grouped as AHB (n=89) and CHB-AE (n=83) based on their history of hepatitis B virus infection and duration of HBsAg persistence. Virological and biochemical parameters were analyzed and compared. Cut-off values, sensitivity, and specificity of the variables were calculated. Results: The median value of signal by cut-off (S/Co) ratio for IgM anti-HBc was significantly higher in AHB group (30.44) compared to CHB-AE group (8.63) with a sensitivity and specificity of 97% and 84%, respectively, at a cut-off of 20.5 (P<0.01). The mean international normalized ratio (INR) was significantly greater in CHB-AE (1.88±1.24) group compared to AHB group (1.62±0.17) with a sensitivity and specificity of 57.9% and 45.1%, respectively, at a cut-off value of 1.27. Conclusions A value of 20.5 S/Co of IgM anti-HBc and 1.27 INR could be helpful in differentiating between AHB and CHB-AE.

PURPOSE: To establish the strength of the association between routine tear function tests and conjunctival impression cytology (CIC) and to determine whether they simulate the morphological and cytological changes that occur on the ocular surface in dry eye. What are the sensitivity, specificity and positive predictive values of these tests when CIC is considered the gold standard? METHODS: The tear film profile included tear film break up time (TBUT), Schirmer's-1, Rose Bengal scores (RBS), and impression cytology. CIC samples were obtained from the inferior bulbar conjunctiva and stained with periodic acid-Schiff and counter stained with hematoxylin and eosin. RESULTS: The mean Schirmer's value was 11.66 +/- 5.90 in patients and 17.17 +/- 2.97 in controls (p < 0.001). The mean TBUT in participants was 8.88 +/- 3.54 and 13.53 +/- 2.12 in controls (p < 0.001). Patients had a mean goblet cell density (GCD) of 490 +/- 213, while the value for controls was 1,462 +/- 661 (p < 0.001). Abnormal CIC was observed in 46.7% cases of dry eye and in 32.8% of controls. The correlation coefficient (L) for Schirmer's was 0.2 and 0.24 for participants and controls, respectively, while TBUT values were 0.26 and 0.38, RBS were 0.5 and 0.5, and GCD was 0.8 and 0.6 in cases and controls, respectively. CONCLUSIONS: GCD, RBS, and TBUT were better predictors of morphological and cytological changes in the conjunctiva than Schirmer's in dry eye syndrome. The sensitivity of tear function tests in diagnosing dry eye was TBUT > Schirmer's > RBS, and the specificity was Schirmer's > TBUT > RBS in decreasing order when CIC was considered the gold standard.

Intrahepatic and extrahepatic anatomical knowledge is essential for pre procedural planning of liver transplantation, liver resection, complex biliary reconstruction and radiological biliary tree intervention. Indian data of biliary anatomy and its variation is scant in literature. The aim of our study is to find out the prevalence of common and uncommon pattern of biliary tree anatomy in magnetic resonance cholangiopancreatography (MRCP) in our population. A total of 1,038 cases of MRCP of population of Odisha were obtained from Picture Archiving and Communication System of the department and were reviewed by two senior radiologists for anatomical pattern and variations. The typical and most common pattern of right hepatic duct (RHD) branching was seen in 72.8% cases. The most common variant of RHD was trifurcation pattern of insertion of right anterior sectoral duct (RASD), right posterior sectoral duct and left hepatic duct (LHD) forming common hepatic duct (CHD) in 11.3% of cases. The common trunk of segment (SEG) II and III ducts joining the SEG IV duct was the most common LHD branching pattern in 90.3% of cases. The most common pattern of cystic duct was posterior insertion to middle third of CHD (42.8%). MRCP is the non-invasive imaging modality for demonstration of biliary duct morphology to prevent iatrogenic injury during hepatobiliary intervention and surgery.
