Sensitive CO observations are presented for a sample of elliptical galaxies which are luminous X-ray and weak far infrared (FIR) emitters. Only non-detections were obtained. The absence of detectable amounts of CO (this includes the previously ‘detected’ prototypical galaxy NGC4472) does not support those standard cooling flow scenarios in which dust grain sputtering reduces the FIR luminosity,...

We describe a 19 year old woman with systemic lupus erythematosus on corticosteroid therapy, who developed bilateral, multiple, gas-forming Salmonella enteritidis leg abscesses and osteomyelitis mimicking deep vein thrombosis. The infection was treated successfully by a combination of surgical drainage and intravenous ceftriaxone, followed by prolonged oral pefloxacin. This rare case of gas-pro...

Pneumothorax by definition is the accumulation of free air or gas in the pleural space. Air may enter the pleural space from any of three sources: the lung itself via a pleuropulmonary leak; the atmosphere via a pleurocutaneous, pleuroesophageal or pleurobronchial communication; or due to the presence of gas-forming organisms in the pleural space. Pneumothorax is classified according to its eti...

A case is reported of subcutaneous emphysema involving upper limb resulting from a trivial laceration to the elbow. Gas in the soft tissues after the injury can be caused by infection with a gas forming organism or by a variety of non-infective causes. It is hypothesised that this minor skin wound has acted like a ball-valve mechanism leading to air being trapped in the soft tissue. (Emerg Med ...

We use the Giant Metrewave Radio Telescope (GMRT) Cold-HI AT $z\approx1$ (CAT$z1$) survey, a 510 hr HI 21cm emission survey of galaxies at $z=0.74-1.45$, to report first measurements atomic hydrogen (HI) scaling relations $z\approx1$. divide our sample 11,419 blue star-forming into three stellar mass ($M_*$) subsamples and obtain detections (at $\geq 4\sigma$ significance) stacked signal from i...
