Wells Mountain Foundation, INC. Scholarships for Third World Countries

Study Subject: Any Area of Interest
Employer: Wells Mountain Foundation, INC
Level:Undergraduate, Graduate
Scholarship Description: The Wells Mountain Foundation is a public charitable foundation based in Bristol, Vermont which has been approved under the United States Internal Revenue Service under Section 501(c)(3). The purpose of the Foundation is primarily to support programs and individuals in third world countries, or other situations of extreme poverty and need.Each year the Foundation provides support to a number of students as they pursue various educational objectives. Typically support is provided for post-secondary school (college, university, polytechnic, trade school). Financial support is primarily to cover the costs of the education itself, and directly related expenses including books, and supplies at the educational institution. In some limited cases the support can be extended to cover other personal expenses
while pursuing the educational objective including food and lodging, travel to and from the educational institution, and other personal needs.
Scholarships will generally be granted for the full period of study, however, recipients must provide copies of all progress reports and grades as they are received and the scholarship can be discontinued at any time in the event of unsatisfactory performance.

Scholarship Application Deadline: July 1, 2011

Post-Doctoral Fellow (m/f) for the X-Ray Microscopy beamline ID21

Post-Doctoral Fellow (m/f) for the X-Ray Microscopy beamline ID21 [18-36m; Ph.D. degree in physics, biology, chemistry or a related discipline; exp in synchrotron radiation (X-ray spectroscopy, X-ray imagin or other microscopy techniques); aptitudes in X-ray instrumentation or data analysis and modeling; exp in vibrational spectroscopy (FTIR or Raman); English] / ESRF; Grenoble / deadline August 31


EUROPEAN SYNCHROTON RADIATION FACILITY
INSTALLATION EUROPEENNE DE RAYONNEMENT SYNCHROTRON

The ESRF is a multinational research institute, situated in Grenoble, France and financed by 19 countries mostly European. It operates a powerful synchrotron X-ray source with some 30 beamlines (instruments) covering a wide range of scientific research in fields such as biology and medicine, chemistry, earth and environmental sciences, materials and surface science, and physics. The ESRF employs about 600 staff and is organized as a French société civile.

Within the Experiments Division, the X-ray Imaging group is now seeking to recruit a:

POST-DOCTORAL FELLOW (M/F)
for the X-Ray Microscopy beamline ID21
T H E F U N C T I O N

You will participate in research programmes, the operation of the instruments and providing support to external users as local contact.
In particular, you will be encouraged to develop your own research programme, which should exploit the unique beamline capabilities (a brief description of the project will be appreciated). You will also join in the effort of the group to upgrade the performance of the experimental end-stations and to develop micro-analysis methodologies, based on X-rays and infrared.
ID21 is an undulator beamline devoted to high resolution micro-analysis and micro-spectroscopy. The beamline comprises two end-stations:

  • a scanning X-ray microscope optimized for X-ray fluorescence and transmission micro-spectroscopy/imaging in the 2-7.2keV range;
  • a synchrotron-based infrared microscope dedicated to FTIR microscopy and spectroscopy. Areas of interest involve the study of elemental distributions, chemical speciation and morphology of samples with sub-micron lateral resolution in fields of applications such as Biology, Geochemistry, Archeometry, or Environmental Sciences.

Q U A L I F I C A T I O N S A N D E X P E R I E N C E

You must hold a student loans and grants degree or equivalent in physics, biology, chemistry or a related discipline. Previous experience in a synchrotron radiation related field such as X-ray spectroscopy techniques, X-ray imaging or/and other microscopy techniques is desirable. Aptitudes in X-ray instrumentation or in data analysis and modeling or in cryo-microscopy would be appreciated. Experience in vibrational spectroscopy (FTIR or Raman) will also be considered as an asset.

A D D I T I O N A L I N F O R M A T I O N

The working language of the ESRF is English. For further information on employment terms and conditions, please refer to www.esrf.fr/Jobs/Conditions. The ESRF is an equal opportunity employer and encourages applications from disabled persons. Further information on the post can be obtained from Marine Cotte (tel.: +33 (0)4 76 88 21 27, email: cotte@esrf.fr).

Post-doctoral fellows are employed for an 18-month period with a possibility of extension to another 6 to 18 months. Only candidates holding a Ph.D. obtained less than 3 years ago are eligible for Post-doctoral positions.
If you are interested, please send an e-mail (recruitment@esrf.fr) together with your CV and the application form, available on www.esrf.fr/Jobs/Applying.

Post-doc Chemistry, In Nice, France rotc scholarship application

Post-doc Chemistry, In Nice, France :
Beasiswa Scholarships : A two-year postdoctoral position is available in the Ion Channel Genetics team at IPMC -

TIANP (UMR CNRS 6097) located at the Science faculty in Parc Varlose in Nice, south of

France ( http://www.unice.fr/tianp).

Subject: TASK K+ channel contribution in breathing adaptation to O2, CO2 and
pH changes

Context of the study


The chemosensitivity is an essential property of the respiratory system to permanently adapt

its activity to the needs of the body. Specialized sensors at the periphery (mainly carotid

bodies) and at the central level (specialized nuclei in the brainstem) are involved in

monitoring arterial blood CO2 and O2 pressures as well as pH. Defects of central

chemoreception are implicated in respiratory pathologies such as sleep apnea syndromes,

periodic breathing in high altitude and drug- or anesthesia-induced respiratory depression.

The congenital central hypoventilation syndrome is a severe hereditary form of central

breathing chemosensitivity in human. The brainstem topology of respiratory nuclei is

relatively well known. Yet, we don't precisely know what are the neurons directly involved in

chemosensitivity and even less the exact molecular identities of the chemoreceptors.

Background K+ channels (K2P) of the TASK family display functional characteristics

including pH and reactive oxygen species (ROS) sensitivities that make them good CO2 and

O2 sensors candidates.

In a recently published work, we have identified TASK2 as the molecular O2 sensor in

retrotrapezoid nucleus (RTN) and proposed that its activation by hypoxia generated ROS is

the mechanism by which central hypoxia-induced ventilatory depression takes place

(Gestreau et al 2010).

Objectives

The project is aimed at the characterization of the molecular mechanisms regulating the CO2

and O2 sensing in the brainstem and involved in the adaptation of breathing to the blood gases

relying on the unique model of TASK mutant mice.

We have produced mice invalidated for the three TASK channel genes task1 (kcnk3), task2

(kcnk5) and task3 (kcnk9) as well as double knockout task1-3 and task2-3. The postdoctoral

fellow will develop patch-clamp studies on brainstem slices from these mouse models.

Therefore, a good experience in electrophysiology, and possibly in electrophysiology on

slices would be greatly appreciated.


Post starting January 2011


Duration 24 months
