Background and Objectives- Tinospora cordifolia (Willd.) Miers ex Hook. f. & Thoms. (T. cordifolia) has been shown to be hepatoprotective by Ayurvedic physicians but has not been scientifically evaluated so far. So, the present study was undertaken to explore the hepatoprotective activity of T. cordifolia against experimentally induced hepatotoxicity in albino rats. Aim of The Study-To explore the hepatoprotective activity of T. cordifolia. Materials and Methods- Albino Wistar rats weighing 150-200g of either sex were divided into six groups of six animals each. Group I was given normal saline (PO), group II carbon tetrachloride(CCl4) (IP), group III Liv.52 syrup for twenty days followed by carbon tetrachloride, group IV, V & VI received aqueous extract of T. cordifolia (1ml/100g twice daily) orally for 10, 20 & 30 days respectively followed by CCl4 administration. Blood was collected from anaesthetized animals & liver was dissected out. Alanine transaminase (ALT), Alkaline phosphatase (ALP) & Total bilirubin were estimated and liver was subjected to histopatological examination. Results-ALT, ALP & Total bilirubin levels were significantly increased in CCl4 treated group while T. cordifolia displayed significant reduction in rise in these parameters in group IV, V & VI. This hepatoprotection was also reflected in histologal changes. Interpretation and Conclusion-It can be concluded from the present study that T. cordifolia extract is a potent hepatoprotective agent. It is assumed that this hepatoprotective effect of T. cordifolia may be due to several reasons such as antioxidant and/or free radical scavenger property and ability to induce hepatic regeneration.

Introduction: Tooth whitening products enjoy substantial popularity. However, tooth hypersensitivity is invariably an undesirable consequence. Desensitizing toothpastes may be used for alleviating the symptoms. Novamin, as an active ingredient in many dentifrices, has been shown to deliver significant therapeutic desensitising benefits. Aim: To study the effect of Novamin desensitising toothpaste mixed with 15% carbamide peroxide on tooth bleaching and tubule occlusion. Material and Methods: This study was carried out in vitro, on extracted premolars which were bleached, using the above mentioned mixture and shade change was evaluated. They were then sectioned to be observed under a scanning Electron Microscope. The number of completely and partially blocked tubules as well as open tubules were counted for each specimen. Statistical analysis for shade change was done by using paired t-test. Mean and Standard deviation were calculated for the tubule counts and they were analyzed statistically. Conclusion: The results of this study indicated that the addition of Novamin to 15% Carbamide peroxide occluded the dentinal tubules and that it did not affect the bleaching procedure. They also emphasized its clinical relevance in a dual advantage of desensitizing and bleaching with a single paste system.

Carpal injuries are uncommon and are mainly seen in the younger age group. The incidence is unclear as many of the cases go undiagnosed. A 22-year-old male patient coming to the hospital after road traffic accidentwith head, face and left wrist injury. After immediate primary management the patient was taken up for a definitive procedure 4 days after the injury. Scaphoid fracture was fixed with the help of Herberts screw via the dorsal approach. The base of the first metacarpal was fixed with the help of JESS fixator and the distal end radius was fixed with the help of K-wires. The scapholunate and lunato triquetral ligaments were repaired. The whole construct was stabilized with the help of an external fixator. Postoperative period was uneventful. The external fixator was removed after 4 weeks and patient had a good functional outcome with the patient related wrist evaluation score coming out to be 11 at the end of the third month. This uncommon case of Transradial, Trans scaphoid, transcapitate, and perilunate dislocation was managed successfully with no postoperative complications and a good functional outcome.

The yeasts Malassezia (M.) pachydermatis and Candida (C.) parapsilosis are often co-isolated in case of canine seborrhea dermatitis (SD) and also are emerging as opportunistic pathogens of immunocompromised human beings. Increased information about how their relationship results in biofilm production and an antifungal response would be useful to inform treatment and control. This study was designed to investigate biofilm production derived from co-culture of M. pachydermatis and C. parapsilosis from dog skin and to determine their in vitro antifungal susceptibility. We demonstrated that regardless of yeast strain or origin all single and dual cultures produced biofilms within 24 hours, and the greatest amount was present after 72 hours. Biofilm production from mixed cultures was greater than for single strains (P < .05). All sessile forms of the single and dual cultures were resistant to the tested antifungals itraconazole and ketoconazole, whereas planktonic forms were susceptible. The study suggests that dual cultures produce stronger biofilms that are likely to enhance persistence in skin lesions in dogs and result in greater resistance to antifungal treatment.

Many aspects of an animal's early development contribute to the emergence of individual differences in physiology. Here we asked whether litter size, birth mass, suckling success and postnatal growth were predictors of individual differences in testosterone (T) and corticosterone (CORT) levels in neonatal domestic rabbits. Serum concentrations of both hormones, which we measured on postnatal day 8, were significantly and positively correlated with pup growth and milk intake. Litter size and birth mass were not significantly correlated with levels of T and CORT, although both parameters were indirectly associated with the levels of these hormones via their effects on milk intake and pup growth. Our results highlight the importance of naturally occurring features of the postnatal environment in shaping individual differences in T and CORT levels during early life. © 2011 Elsevier Inc.

In this work, IS200 and multi-locus sequence typing (MLST) were used to analyze 19 strains previously serotyped as Salmonella enterica serovar Typhi and isolated in Indonesia (16 strains), Mexico (2 strains), and Switzerland (1 strain). Most of the strains showed the most common Typhi sequence types, ST1 and ST2, and a new Typhi genotype (ST1856) was described. However, one isolate from Mexico and another from Indonesia were of the ST365 and ST426 sequence types, indicating that they belonged to serovars Weltevreden and Aberdeen, respectively. These results were supported by the amplification of IS200 fragments, which rapidly distinguish Typhi from other serovars. Our results demonstrate the utility of IS200 and MLST in the classification of Salmonella strains into serovars. These methods provide information on the clonal relatedness of strains isolated worldwide. © 2015, Sociedad Espanola de Microbiologia. All rights Reserved.

Many factors put Mongolians at risk of vitamin D deficiency. Despite low levels observed in Mongolian children and pregnant women, there are few data published on the vitamin D status of non-pregnant adults. Between summer 2011 and winter 2013, paired summer and winter blood samples were collected from 320 healthy men and women (20-58 years) living in eight Mongolian provinces. Mean serum 25(OH)D concentrations were 22.5 ng/mL (95% CI: 14.5, 32.5) in summer and 7.7 ng/mL (95% CI: 4.6, 10.8) in winter, with a distribution (<10/10-20/20-30/30 ng/mL) of 3.1%/39.3%/39.6%/17.9% in summer and 80.1%/19.5%/0.3%/0.0% in winter. Residents of the capital, Ulaanbaatar, had lower levels in both seasons than any other region, whereas residents of the Gobi desert had the highest. In summer, indoor workers had significantly lower levels than outdoor workers (-2.3 ng/mL; 95% CI: -4.1, -5.7) while levels in males exceeded those in females (4.0 ng/mL; 95% CI: 2.3, 5.7). Effects of region, occupation, and sex were also significant in multivariable regression. In conclusion, Mongolian adults had extremely low serum 25(OH)D, particularly in winter, when 80.1% had concentrations below 10 ng/mL. These results indicate a need for effective vitamin D interventions for the Mongolian adult population, particularly among women and residents of Ulaanbaatar.

Acne scarring causes cosmetic discomfort, depression, low self-esteem and reduced quality of life. Microneedling is an established treatment for scars, although the efficacy of platelet-rich plasma (PRP) has not been explored much.The objective of this study was to evaluate the efficacy and safety of platelet-rich plasma (PRP) combined with microneedling for the treatment of atrophic acne scars.Fifty patients of 17-32 years of age with atrophic acne scars were enrolled. Microneedling was performed on both halves of the face. Intradermal injections as well as topical application of PRP was given on right half of the face, while the left half of the face was treated with intradermal administration of distilled water. Three treatment sessions were given at an interval of 1 month consecutively. Goodmans Quantitative scale and Quantitative scale were used for the final evaluation of results.Right and left halves showed 62.20% and 45.84% improvement, respectively, on Goodmans Quantitative scale. Goodmans Qualitative scale showed excellent response in 20 (40%) patients and good response in 30 (60%) patients over right half of the face, while the left half of the face showed excellent response in 5 (10%) patients, good response in 42 (6%) patients and poor response in three patients.We conclude that PRP has efficacy in the management of atrophic acne scars. It can be combined with microneedling to enhance the final clinical outcomes in comparison with microneedling alone.

Scrub typhus is an acute febrile illness which has been reported from various parts of India with Rajasthan recently joining the list of affected states.To report a series of paediatric scrub typhus cases from rural Rajasthan.Retrospective review of children with scrub typhus admitted to the wards and paediatric intensive care unit (PICU) of a tertiary-care hospital.The study was undertaken over an 8-month period from May to December 2013. All patients with a clinical presentation and/or serological confirmation of scrub typhus who tested negative for malaria, enteric fever, dengue, leptospirosis and urinary tract infection (UTI) were included. A range of investigations were undertaken including IgM-ELISA for scrub typhus, followed by appropriate medical management.Thirty patients satisfied the inclusion criteria. The mean (SD, range) age of the patients was 856 (343, 3-16) years. The most common clinical features were fever (n=30, 100%), headache (n=20, 66%), myalgia (n=15, 50%), hepatosplenomegaly (n=18, 60%) and pallor (n=5, 16%). Typical features such as eschar and rash were observed in only one (33%) and three (10%) patients, respectively; none had generalised lymphadenopathy or conjunctival congestion. IgM-ELISA for scrub typhus was positive in 28 patients (933%) and 27 responded to doxycycline within 24-72hours. One of the three patients who required PICU support responded to intravenous chloramphenicol and, of the other two (66%), one died of acute respiratory distress syndrome and the other owing to acute renal failure.A high index of suspicion is essential for early diagnosis and prevention of complications in scrub typhus together with prompt referral from rural areas to a higher centre. Awareness of the disease manifestations may further help to prevent excessive investigations in patients presenting with non-specific febrile illness and reduce the economic burden to the family and society in resource-constrained settings.
