Prognostic significance of pre- and post-operative serum carcinoembryonic antigen levels in patients presented with rectal carcinoma; an experience from Shaukat Khanum Memorial Cancer Hospital and Research Center Lahore.

Objective: To explore the importance of serum carcinoembryonic antigen level as a tumour marker in rectal carcinoma.

Methods: The retrospective study was conducted at Shaukat Khanum Memorial Cancer Hospital, Lahore, Pakistan, and comprised data of patients with rectal carcinoma from January 1996 to December 2015. Serum carcinoembryonic antigen levels were analysed using immulite@2000 system analyser.

A clinical study and treatment results of adrenocortical carcinoma patients presented in Shaukat Khanum Memorial Cancer Hospital and Research Center, Lahore.

Adrenocortical carcinoma is a rare and aggressive malignancy with an incidence of 0.5-2 per million per year and its overall prognosis is very poor. This study was aimed to point out the factors associated with tumour recurrence and patient's survival after complete surgical resection of this aggressive malignancy.

Risk factors effecting development of metachronous liver metastasis in rectal cancer patients after curative surgical resection. Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore experience.

Objective: To determine risk factors affecting development of metachronous liver metastasis in rectal cancer patients after curative surgical resection.

Methods: The retrospective cohort study was conducted at Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, Pakistan, and comprised data of patients with histologically proven rectal carcinoma admitted to the department of surgical oncology from January 2005 to December 2015. Clinical data of all patients, including age, gender, clinical presentation, clinical and pathological tumour-nodes-metastasis classification, neoadjuvant chemo-radiotherapy, surgery, adjuvant chemotherapy, pre- and postoperative carcinoembryonic antigen levels, histopathological findings and tumour recurrence were analysed.

A case for using ground-based thermal inertia measurements to detect Martian caves.

Martian caves are regarded as one of the most interesting locations in which to search for life on the planet. Data obtained during the MARS2013 expedition at Hamar Laghdad Ridge in the Tafilalt region of Morocco indicate that even small cavities can display thermal behavior that is characteristic for caves. For example, temperature in a cavity equaled 14°C±0.

Field trial of a dual-wavelength fluorescent emission (L.I.F.E.) instrument and the Magma White rover during the MARS2013 Mars analog mission.

Abstract We have developed a portable dual-wavelength laser fluorescence spectrometer as part of a multi-instrument optical probe to characterize mineral, organic, and microbial species in extreme environments. Operating at 405 and 532 nm, the instrument was originally designed for use by human explorers to produce a laser-induced fluorescence emission (L.I.

The MARS2013 Mars analog mission.

We report on the MARS2013 mission, a 4-week Mars analog field test in the northern Sahara. Nineteen experiments were conducted by a field crew in Morocco under simulated martian surface exploration conditions, supervised by a Mission Support Center in Innsbruck, Austria. A Remote Science Support team analyzed field data in near real time, providing planning input for the management of a complex system of field assets; two advanced space suit simulators, four robotic vehicles, an emergency shelter, and a stationary sensor platform in a realistic work flow were coordinated by a Flight Control Team.
