Somaiya College of Sc. & Comm 077, India. The nonresonant third order nonlinear optical properties of three different sized Mn-doped ZnSe quantum dots (QDs) are investigated. The nonlinear absorption ...

BACKGROUND Head and neck squamous cell carcinomas (HNSCC) are treated by surgery or radiotherapy. Tumor cell death-related markers, such as p21 and Ki-67, may predict response to therapy and improve treatment choice. We evaluated and compared the effect of their coexpression between patients treated by surgery or radiotherapy. METHODS Immunohistochemistry for p21 and Ki-67 expression in 144 p...

Four experiments involving 163 pigs were conducted to determine the effects of iodine level in a corn-soybean meal diet on body weight gain, feed required per unit gain and thyroid status. Pigs fed the basal diet (.055 ppm iodine) with no supplemental iodine had lower plasma protein-bound-iodine levels, hypertrophied thyroids and trapped a greater amount of a 5 /~c dose of radioiodine (l st I) ...

The authors compared ACTN3 R577X genotype and allele frequencies in the majority of all-time-best Spanish judo male athletes (n = 108) and 343 ethnically matched nonathletic men. No between-groups differences were found in allele (P = .077) or genotype distributions (P = .178). Thus, the R577X polymorphism was not significantly associated with the status of being an elite judo athlete, at least...

Mortalin/mtHsp70 is a member of Hsp70 family of proteins. Enriched in a large variety of cancers, it has been shown to contribute to the process of carcinogenesis by multiple ways including inactivation of tumor suppressor p53 protein, deregulation of apoptosis and activation of EMT signaling. In this study, we report that upregulation of mortalin contributes to cancer cell stemness. Several ca...
