Dietary Calcium Induced Cytological And Biochemical Changes In Thyroid, Amar K. Chandra, Haimanti Goswami, Pallav Sengupta

Pallav Sengupta, PhD

Certain epidemiological studies revealed correlation between hard water consumption (with high calcium) and thyroid size of the population, though the possible alterations in thyroid physiology upon calcium exposure are still inconclusive. Adult male Wistar strain rats were subjected to calcium treatment at the doses of 0.5g%, 1.0g% and 1.5g% calcium chloride (CaCl2) for 60 days. The parameters studied were -thyroid gland weight, histopathology, histomorphometry; thyroid peroxidase (TPO), 5'- deiodinase I (DI), sodium-potassium adenosine triphosphatase (Na+-K+-ATPase) activities; serum total and free thyroxine (tT4, fT4), total and free triiodothyronine (tT3, fT3), thyroid stimulating hormone (TSH) levels.

Biodiversity Status In Ethiopia And Challenges, Azamal Husen, V.K. Mishra, Kamal Semwal, Dinesh Kumar

Prof. Azamal Husen

Ethiopia is rich in faunal, floral and microbial diversity. Conservation paradigms, practices and policies have been variably successful. Traditional approaches in conservation have evolved awareness about biodiversity conservation. Climate change poses unknown fear and challenge to biodiversity conservation in the 21st century. There is urgent need of mapping of biodiversity in various environments, inventorization, monitoring of biodiversity, and global data sharing. Conservation of genetic resources will assist in future genetic improvement of crop plants and livestocks. Bioprospecting-value addition to biodiversity will provide economic gain for the country. Necessary measures need to be initiated to safeguard the germplasms against potential threat …


The Mc159 Protein From The Molluscum Contagiosum Poxvirus Inhibits Nf-Kb Activation By Interacting With The Ikb Kinase Complex, Crystal Randall Dec 2011

The Mc159 Protein From The Molluscum Contagiosum Poxvirus Inhibits Nf-Kb Activation By Interacting With The Ikb Kinase Complex, Crystal Randall

Crystal Randall

Molluscum contagiosum virus (MCV) causes persistent neoplasms in healthy and immunocompromised people. Its ability to persist likely is due to its arsenal of viral immunoevasion proteins. For example, the MCV MC159 protein inhibits TNF-R1 induced NF-kB activation and apoptosis. The MC159 protein is a viral FLIP and, as such, possesses two tandem death effector domains (DEDs). We show in this article that, in human embryonic kidney 293 T cells, the expression of wild-type MC159 or a mutant MC159 protein containing the first DED (MC159 A) inhibited TNF-induced NF-kB, or NF-kB activated by PMA or …

The Role Of Tooth Enamel Mechanical Properties In Primate Dietary Adaptation, Paul J. Constantino, James Jw Lee, Yvonne Gerbig, Adam Hartstone-Rose, Mauricio Talebi, Brian Lawn, Peter Lucas

Paul J. Constantino

Primate teeth adapt to the physical properties of foods in a variety of ways including changes in occlusal morphology, enamel thickness, and overall size. We conducted a comparative study of extant primates to examine whether their teeth also adapt to foods through variation in the mechanical properties of the enamel. Nanoindentation techniques were used to map profiles of elastic modulus and hardness across tooth sections from the enamel-dentin junction to the outer enamel surface in a broad sample of primates including apes, Old World monkeys, New World monkeys, and lemurs. The measured data profiles feature considerable overlap among species, indicating …

7 Alpha-Hydroxy-Beta-Sitosterol From Chisocheton Tomentosus Induces Apoptosis Via Dysregulation Of Cellular Bax/Bcl-2 Ratio And Cell Cycle Arrest By Downregulating Erk1/2 Activation, Noor Hasima Nagoor

Noor Hasima Nagoor

In continuation of our interest towards the elucidation of apoptotic pathways of cytotoxic phytocompounds, we have embarked upon a study on the anticancer effects of 7 alpha-hydroxy-beta-sitosterol (CT1), a rare natural phytosterol oxide isolated from Chisocheton tomentosus. CT1 was found to be cytotoxic on three different human tumor cell lines with minimal effects on normal cell controls, where cell viability levels were maintained >= 80% upon treatment. Our results showed that cell death in MCF-7 breast tumor cells was achieved through the induction of apoptosis via downregulation of the ERK1/2 signaling pathway. CT1 was also found to increase proapoptotic Bax …


Economic Impact Of Stable Flies (Diptera: Muscidae) On Cattle Production., David B. Taylor, Roger D. Moon, Darrell R. Mark Dec 2011

Economic Impact Of Stable Flies (Diptera: Muscidae) On Cattle Production., David B. Taylor, Roger D. Moon, Darrell R. Mark

David B Taylor

Stable flies, Stomoxys calcitrans (L), are among the most damaging arthropod pests of cattle worldwide. The last estimate of their economic impact on US cattle production was published 20 years ago and placed losses at $608 million. Subsequently, several studies of effects of stable flies on beef cattle weight gain and feed efficiency have been published, and stable flies have become increasingly recognized as pests of cattle on pasture and range. We analyzed published studies and developed yield-loss functions to relate stable fly infestation levels to cattle productivity, and then estimated the economic impact of stable flies on cattle production …

This article claims that the United States is progressing well when examined through the racial and cultural diversity of its young people aged 29 and younger with earned doctorates. The data show that females in general and Asian and Black females in particular are earning very high proportions of doctorate degrees among individuals aged 29 and younger in 2009 and 2008. For example, of the 117,000 doctorate degrees (Ph.D., Ed.D., etc.) held by individuals in the US aged 25 - 29 in 2009, females accounted for 65,000 (55.6%), with Black females and Asian females accounting for 11.1% (13,000) and 10.3% …


This Shrew Is A Jumping Mouse (Mammalia, Dipodidae): Sorex Dichrurus Rafinesque, 1833 Is A Synonym Of Zapus Hudsonius (Zimmermann, 1780), Neal Woodman Dec 2011

This Shrew Is A Jumping Mouse (Mammalia, Dipodidae): Sorex Dichrurus Rafinesque, 1833 Is A Synonym Of Zapus Hudsonius (Zimmermann, 1780), Neal Woodman

Neal Woodman

Constantine S. Rafinesque described Sorex dichrurus as a shrew in 1833, based on a specimen he found in a proprietary museum near Niagara Falls on the New York/Ontario border. The name subsequently has been ignored by the scientific community. By describing this specimen as a shrew and ascribing it to the genus Sorex, Rafinesque clearly indicated that his species should be considered a member of the taxonomic family now recognized as the Soricidae (Mammalia, Eulipotyphla). Yet, the description of the animal, and its comparison to ‘‘Gerbillus,’’ clearly identify it as a dipodid rodent, specifically Zapus hudsonius (Zimmermann, 1780); S. dichrurus …


Resampling-Based Information Criteria For Best-Subset Regression, Philip T. Reiss, Lei Huang, Joseph E. Cavanaugh, Amy Krain Roy Dec 2011

Resampling-Based Information Criteria For Best-Subset Regression, Philip T. Reiss, Lei Huang, Joseph E. Cavanaugh, Amy Krain Roy

Philip T. Reiss

When a linear model is chosen by searching for the best subset among a set of candidate predictors, a fixed penalty such as that imposed by the Akaike information criterion may penalize model complexity inadequately, leading to biased model selection. We study resampling-based information criteria that aim to overcome this problem through improved estimation of the effective model dimension. The first proposed approach builds upon previous work on bootstrap-based model selection. We then propose a more novel approach based on cross-validation. Simulations and analyses of a functional neuroimaging data set illustrate the strong performance of our resampling-based methods, which are …


Inadequate Feeding Of Infant And Young Children In India: Lack Of Nutritional Information Or Food Affordability?, Nisha Malhotra Dec 2011

Inadequate Feeding Of Infant And Young Children In India: Lack Of Nutritional Information Or Food Affordability?, Nisha Malhotra

Nisha Malhotra

Why does child malnutrition persist in India? Amongst the fastest growing economies over the last two decades, India has struggled to make progress in the health of its children. In this article the author argues that the reason malnutrition persists is not limited to poverty or inadequate access to food; but that a lack of nutritional knowledge amongst families plays a very important role.

Scientific Abstract Objective: Despite a rapidly growing economy and rising income levels in India, improvements in child malnutrition have lagged. Data from the most recent National Family Health Survey reveal that the infant and young child …
