Club cells form lung adenocarcinomas and maintain the alveoli of adult mice

Pten controls lung morphogenesis, bronchioalveolar stem cells, and onset of lung adenocarcinomas in mice.

PTEN is a tumor suppressor gene mutated in many human cancers. We generated a bronchioalveolar epithelium-specific null mutation of Pten in mice [SP-C-rtTA/(tetO)(7)-Cre/Pten(flox/flox) (SOPten(flox/flox)) mice] that was under the control of doxycycline. Ninety percent of SOPten(flox/flox) mice that received doxycycline in utero [SOPten(flox/flox)(E10-16) mice] died of hypoxia soon after birth....

P-74: Crocin Repopulate The Leydig and Sertoli Cells in Testis of Cyclophosphamide Treated Adult Mice

Background: Increases in the survival rate of men treated with chemotherapeutic drugs and their desire to have children precipitate concerns about the effects of these drugs on germ cells. This study performed to evaluation of protective effects of crocin in oxidative stress induced by cyclophosphamide (CP) on testis. Materials and Methods: Three groups (6 mice in each) of adult mice were used....

the analysis of the role of the speech acts theory in translating and dubbing hollywood films

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...

Lung alveoli: endogenous programmed destruction and regeneration.

Mammalian alveoli, complex architectural and cellular units with dimensions that are linked to the organism's O2 consumption (VO2), are thought to be destroyed only by disease and not to spontaneously regenerate. Calorie restriction of adult mammals lowers VO2, and ad libitum refeeding returns VO2 to pre-calorie-restriction values. We took advantage of these relationships and tested the hypothe...
