We report limits in the planetary-mass regime for companions around the nearest single white dwarf to the Sun, van Maanen’s star (vMa 2), from deep J-band imaging with Gemini North and Spitzer Infrared Array Camera (IRAC) mid-IR photometry. We find no resolved common proper motion companions to vMa 2 at separations from 3 to 45 arcsec, at a limiting magnitude of J ≈ 23. Assuming a total age for...

Loss of V-ATPase activity in organelles, whether through V-ATPase inhibition or V-ATPase (vma) mutations, triggers a compensatory downregulation of the essential plasma membrane proton pump Pma1 in Saccharomyces cerevisiae We have previously determined that the α-arrestin Rim8 and ubiquitin ligase Rsp5 are essential for Pma1 ubiquination and endocytosis in response to loss of V-ATPase activity....

BACKGROUND Stress is a normal part of everyday life but chronic stress can lead to a variety of stress-related illnesses including hypertension, anxiety, and depression. In the present investigation, standardized leaf extract of Epipremnumaureum was evaluated for its anti-stress potential. MATERIALS AND METHODS For the evaluation of anti-stress activity, groups of mice (n = 6) were subjected ...

We investigated whether spatial resolution would be the same in the lower and upper halves of the vertical meridian (VM) of our visual field and whether attention would affect them differentially. It has been reported that (1) attending to the target's location improves performance in a texture segregation task when the observer's spatial resolution is too low (peripheral locations) but impairs...

Nyctanthes arbor-tristis, (Fam. Oleaceae) is commonly known as Parijatham, Harsinghar and Night Jasmine. Different parts of Nyctanthes arbor-tristis are known to possess various ailments by rural mainly tribal people of India along with its use in Ayurveda, Sidha and Unani systems of medicines. They have also been investingated for various pharmacological actions. Water soluble fraction of etha...

This research was carried out on a laboratory experimental scale, with the aim of determining characteristics Marshall test for substitution Polypropylene plastic pellets in Asphalt Concrete Binder Course (AC BC) mixture. The AC BC mixture is 1%, 2%, 3% weight filler standard From results, it can be concluded that marshall include VMA values, VIM VFA stability flow MQ values meet predetermined ...

This study was undertaken to investigate the effects of green tea on weight reduction in obese Thais. A randomized, controlled trial involving 60 obese subjects (body mass index, BMI > 25 kg/m2) was conducted. All subjects consumed a Thai diet containing 3 meals (8373.6 kJ/day) for 12 weeks, prepared by the Nutritional Unit at Srinagarind Hospital. The diet contained 65% carbohydrates, 15% prot...
