Diabetes in California: Findings From the 2001 California Health Interview Survey
Examines the prevalence of diabetes in California, with particular attention paid to disparities between different population groups. Includes access to medical care, diabetes care and management, and identifying at-risk populations
Anti-microbial screening of some sulphonanilide complexes with Tm(III) ion against gram positive cocci & gram negative bacilli
A series of different sulphonanilide complexes with Tm(III) metal ion were prepared and the systems have been screened for anti-microbial activities by Bauer-Kirby discdiffusion technique against bacterial species such as Staphylococcus aureus, Pseudomonas aeruginosa and E.Coli (gram positive and gram negative) and were found to have moderate to significant activity against bacterialspecies
Alternatively activated macrophages promote pancreatic fibrosis in chronic pancreatitis.
Chronic pancreatitis (CP) is a progressive and irreversible inflammatory and fibrotic disease with no cure. Unlike acute pancreatitis (AP), we find that alternatively activated macrophages (AAMs) are dominant in mouse and human CP. AAMs are dependent on interleukin (IL)-4 and IL-13 signalling, and we show that mice lacking IL-4Rα, myeloid-specific IL-4Rα and IL-4/IL-13 were less susceptible to pancreatic fibrosis. Furthermore, we demonstrate that mouse and human pancreatic stellate cells (PSCs) are a source of IL-4/IL-13. Notably, we show that pharmacologic inhibition of IL-4/IL-13 in human ex vivo studies as well as in established mouse CP decreases pancreatic AAMs and fibrosis. We identify a critical role for macrophages in pancreatic fibrosis and in turn PSCs as important inducers of macrophage-alternative activation. Our study challenges and identifies pathways involved in crosstalk between macrophages and PSCs that can be targeted to reverse or halt pancreatic fibrosis progression
Deep Over-sampling Framework for Classifying Imbalanced Data
Class imbalance is a challenging issue in practical classification problems
for deep learning models as well as traditional models. Traditionally
successful countermeasures such as synthetic over-sampling have had limited
success with complex, structured data handled by deep learning models. In this
paper, we propose Deep Over-sampling (DOS), a framework for extending the
synthetic over-sampling method to exploit the deep feature space acquired by a
convolutional neural network (CNN). Its key feature is an explicit, supervised
representation learning, for which the training data presents each raw input
sample with a synthetic embedding target in the deep feature space, which is
sampled from the linear subspace of in-class neighbors. We implement an
iterative process of training the CNN and updating the targets, which induces
smaller in-class variance among the embeddings, to increase the discriminative
power of the deep representation. We present an empirical study using public
benchmarks, which shows that the DOS framework not only counteracts class
imbalance better than the existing method, but also improves the performance of
the CNN in the standard, balanced settings
Multiplex PCR for Detection of Herpes Simplex Viruses Type-1 and Type-2, Cytomegalovirus, Varicella-zoster Virus, and Adenovirus in Ocular Viral Infections
Purpose: Most common viruses causing ocular infections are Herpes Simplex Viruses (HSV) type 1 and type 2, Cytomegalovirus (CMV), Varicella-zoster Virus (VZV), and few strains of Adenovirus. Diagnosis of these infections through clinical manifestations and using conventional methods has a number of limitations. The purpose of this study was to develop a multiplex Polymerase Chain Reaction (PCR) for simultaneous detection of all pathogenic viruses from ocular infections.
Methods: Ten uniplex PCRs were standardized, two each for HSV type 1 (HSV-1) and type 2 (HSV-2), CMV, VZV, and Adenovirus. Various multiplexing combinations of above PCRs were put to finalize targets and reaction conditions enabling diagnosis of all in a single reaction. The uniplex and multiplex PCRs were run for known positive and negative controls, and samples from clinically suspected patients and healthy controls.
Results: Out of the 170 samples from suspected ocular infections, 24.7% were positive by uniplex PCR and 22.9% were correctly identified by multiplex PCR. None of the samples negative by uniplex PCRs was positive by the multiplex PCR. The sensitivity and specificity of multiplex PCR compared to the commonly used uniplex PCRs as gold standard was 92.86% and 100%, respectively. The prevalence of different viral pathogens was 13.5% for HSV-1, followed by 5.9% for Adenovirus, 2.4% for VZV, 1.8% for HSV-2, and 1.2% for CMV.
Conclusion: The establishment of multiplex PCR has found immediate application in diagnosing ocular viral pathogens in a single reaction, thus saving time, manpower, and resources by fivefold
Yolk sac tumor, a rare and challenging ovarian malignancy: case report
Yolk sac tumors (YST) are rare and rapidly developing neoplasm presenting in young females. They are second most common germ cell tumor after dysgerminomas. Fertility preservation is an important concern in treatment of patients of YST. We present a case of 22 years nulliparous female with rapidly evolving abdominal mass. The patient underwent fertility preserving surgery with four cycles of post operative bleomycin etoposide and paclitaxel (BEP) chemotherapy and is fairly doing well. BEP chemotherapy has successfully improved the treatment outcomes of YST patients
Correlation between mutans streptococci counts of parents and their children residing in Chandigarh, India
Objectives: To determine the prevalence of Mutans Streptococci (MS) in children and to evaluate the relationship
between the salivary levels of MS in children and their parents.
Material and Methods: 100 children aged 3-6 years along with their parents (100 mothers and fathers each) were
included in the study. The children were segregated depending upon their age and level of caries experience. The
children were examined clinically on an ordinary chair in natural daylight using the Møller's index criteria. Assays
for Mutans Streptococci (MS) were done for both the children and their parents using the Dentocult SM strip mu

tans test. Collected data was assessed using SPSS software.
Results: The overall prevalence of MS in the children was 83%. A statistically significant correlation (p<0.05) was
observed between salivary MS counts of children and their mothers. No significant correlation was seen with the
fathers.
Conclusions: The findings conclude that if primary caregivers harbour high levels of MS in their saliva, it is likely
that their children will have the same
