This study identified and characterized hydrolytic enzymes in salivary gland products of Oestrus ovis larvae. Third instars were collected from the heads of slaughtered goats. Salivary glands were extracted, their products obtained by centrifugation and the enzymatic profile determined. Optimum pH, temperature of maximum proteolytic activity, thermal stability, and resistance of salivary gland ...

Mouse submandibular salivary gland cells and liver progenitor cells from long-term in vitro cultures with a high proliferation potential were side-by-side compared by methods of immunocytochemistry, quantitative real-time PCR, flow cytometry, and transcriptome analysis. The two cell types were found to be similar in expressing cell markers such as EpCAM, CD29, c-Kit, Sca-1, and c-Met. In additi...

Sixty healthy pregnant women (aged 21-35 years), including 30 pregnant women at the beginning of second trimester and 30 women at the beginning of third trimester underwent a psychosocial stress test. Physiological (salivary free cortisol levels, salivary alpha-amylase levels) and psychological (perceived stress, mood, anxiety) responses to standardized psychosocial stress have been brought in ...

Attenuated reactivity of salivary alpha-amylase has been proposed as a specific sympathetic marker of disruptive behavior in juveniles and may have additional value to studying other autonomic parameters and hypothalamic-pituitary-adrenal axis activity. Investigating the interrelationships between neurobiological parameters in relation to juvenile disruptive behavior may enhance insight into th...

A neoplastic salivary cell line with an ultrastructure similar to that of an intercalated duct cell of the salivary gland, established from a human submandibular salivary gland, has been used in our laboratory as a model for studying mechanisms regulating cytodifferentiation in salivary glands. The expression of neurofilaments (Mr 200,000, 160,000, and 68,000) in the neoplastic human salivary i...

The immunohistochemistry study made on 30 cases of salivary glands pleomorphic adenomas aims to establish the antigen profile of luminal epithelial neoplastic component proliferates into these tumors. We ascertain that luminal epithelial neoplastic cell were almost exclusively positive to antibody peculiar to epithelial differentiation (AE1/AE3, MNF 116, CK 8, CK 19, CK20, EMA) and occasional t...

background: infl ammatory cytokines such as interleukin-6 (il-6) and tumor necrosis factor-alpha (tnf-α) are elevated in end-stage renal disease (esrd). il-6 and tnf-α are toxins which deteriorate renal function, and their pathogenic role has been confi rmed in cardiovascular and oral diseases. this study was designed to investigate the salivary levels of il-6 and tnf-α in patients with esrd un...

Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles.  Methods: A total of 80 players, aged 18 to 30 years, played four types of video games;  Ru...

The age-dependent development of alpha-amylase expression in utero and during the first two years of life is reported. Separation of salivary and pancreatic amylase isozymes in a discontinuous buffered sheet polyacrylamide electrophoretic system, with subsequent densitometry, provides a reliable semiquantitative method of estimating the proportions of salivary and pancreatic amylases in urine a...

In a quantitative bacteriological study of the salivary flora from 50 children the following aerobic organisms were identified and enumerated: alpha-haemolytic streptococci, beta-haemolytic streptococci, Streptococcus faecalis, pneumococci, Staphylococcus aureus, Staph. albus and Staph. citreus, Neisseria spp, N. meningitidis, corynebacteria, aerobic lactobacilli, B. subtilis, H. influenzae, co...
