OBJECTIVETo evalueate hepatoprotective effects Feronia elephantum (F. elephantum) correa against thioacetamide (TA) induced liver necrosis in diabetic rats.
METHODSMale wistar rats were made diabetic with alloxan (160 mg/kg) on day 0 of the study. They were intoxicated with hepatotoxicant (thioacetamide, 300 mg/kg, ip) on day 9 of study to produce liver necrosis. Effects of 7 day daily once administration (day 2 to day 9) of EF (400 and 800 mg/kg, po) were evaluated on necorosis of liver in terms of mortality, liver volume, liver weight, serum aspartate aminotransferase (AST) and serum alanine transaminase (ALT), and histopathology of liver sections (for signs of necorosis and inflammation) on day-9 of the study. Separate groups of rats with treated only with alloxan (DA control), thioacetamide (TA control) and both (TA+DA control) were maintained.
RESULTSFE significantly lowered the mortality rate and showed improvement in liver function parameters in TA-induced diabetic rats without change in liver weight, volume and serum glucose levels.
CONCLUSIONSFE showed promising activity against TA-induced liver necorsis in diabetic rats and so might be useful for prevention of liver complications in DM.

BACKGROUND:
As lung ultrasound (LUS) can be used to identify regional lung ventilation and collapse, we hypothesize that LUS can be better than auscultation in assessing lung isolation and determining double lumen tube (DLT) position.
METHODS:
A randomized controlled study was conducted in tertiary care cancer institute from November 2014 to December 2015, including 100 adult patients undergoing elective thoracic surgeries. Patients with tracheostomy, difficult airway and pleural-based pathologies were excluded. After anesthesia induction and DLT insertion, patients were randomized into group A (auscultation) and group B (LUS). Regional ventilation was assessed by experienced anesthesiologists using the respective method for each group. Final confirmation of DLT position with a bronchoscope was performed by a blinded anesthesiologist. Contingency tables were plotted to determine sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for each method.
RESULTS:
Data from 91 patients were analyzed (group A = 47, group B = 44). Compared with auscultation, LUS had significantly higher sensitivity (94.1% vs. 73.3%, P = 0.010), PPV (57.1% vs. 35.5%, P = 0.044), NPV (93.8% vs. 75.0%, P = 0.018), accuracy (70.5% vs. 48.9%, P = 0.036) and required longer median time (161.5 vs. 114 s, P < 0.001) for assessment of DLT position. Differences in specificity (55.6% vs. 37.5%, P = 0.101) and area under curve (0.748; 95% CI: 0.604–0.893 vs. 0.554, 95% CI: 0.379–0.730; P = 0.109) were not significant.
CONCLUSIONS
Compared to auscultation, LUS is a superior method for assessing lung isolation and determining DLT position.

Tissue engineering is a research domain that deals with the growth of various kinds of tissues with the help of synthetic composites. With the culmination of nanotechnology and bioengineering, tissue engineering has emerged as an exciting domain. Recent literature describes its various applications in biomedical and biological sciences, such as facilitating the growth of tissue and organs, gene delivery, biosensor-based detection, etc. It deals with the development of biomimetics to repair, restore, maintain and amplify or strengthen several biological functions at the level of tissue and organs. Herein, the synthesis of nanocomposites based on polymers, along with their classification as conductive hydrogels and bioscaffolds, is comprehensively discussed. Furthermore, their implementation in numerous tissue engineering and regenerative medicine applications is also described. The limitations of tissue engineering are also discussed here. The present review highlights and summarizes the latest progress in the tissue engineering domain directed at functionalized nanomaterials.

Isolated metastatic deposits of papillary thyroid carcinoma to the parapharyngeal space are rare. Herein, we describe the case of a young woman who presented with a right-sided oropharyngeal mass that was initially diagnosed as a parapharyngeal space paraganglioma. The patient opted for conservative treatment as she was asymptomatic and wished to avoid the risk of neurovascular morbidity associated with surgery. After 20 years, the patient sought treatment again for the oropharyngeal mass, which had progressively increased in size and was causing difficulty in swallowing. Repeat imaging of the affected area revealed that the mass had increased significantly in size; it also revealed the presence of a previously absent small lesion in the right lobe of the thyroid. Excision of the parapharyngeal space tumour and near-total thyroidectomy were performed; the excised specimens showed features of the follicular variant of papillary thyroid carcinoma. As papillary thyroid carcinoma that metastasises to the parapharyngeal space can masquerade as a paraganglioma, clinicians should bear in mind that an isolated metastatic deposit in the parapharyngeal space could be the first sign of occult papillary thyroid carcinoma.

BACKGROUND: Plasma cell leukemia (PCL) is a rare and aggressive plasma cell neoplasm. In PCL, clonal plasma cells comprise ≥20% of the peripheral blood (PB) leukocytes and/or the absolute clonal PB plasma cell count is ≥2×10(9)/L. Primary PCL (PPCL) originates de novo, whereas, secondary PCL (SPCL) evolves from pre-existing multiple myeloma. METHODS: Clinicohematological features, immunophenotypic profile, and survival of PCL patients were analyzed retrospectively. RESULTS: Between January 2007 and December 2014, ten PPCL and four SPCL patients were investigated (8 PPCLs and 3 SPCLs had complete clinical data). All were North Indians, sharing common geography and ethnicity. Our cohort showed less frequent renal failure, more frequent hepatomegaly, and non-secretory type disease. In contrast to western literature, flow cytometric immunophenotyping of our cohort revealed altered expression of CD138 (67%), CD56 (33%), and CD20 (0%). With novel therapeutic agents, these PPCL patients had a median overall survival of 15 months. CONCLUSION: We highlight that our PPCL patients from North India had distinct clinicohematological and immunophenotypic profiles. The significance of our findings must be tested in a larger patient cohort and must be supported by molecular and cytogenetic investigations to unmask possible significant effects on pathogenesis.
