In the Sonora Margin cold seep ecosystems (Gulf of California), sediments underlying microbial mats harbor high biogenic methane concentrations, fueling various microbial communities, such as abundant lineages of anaerobic methanotrophs (ANME). However, the biodiversity, distribution, and metabolism of the microorganisms producing this methane remain poorly understood. In this study, measuremen...

In recent years, with the frequent occurrence of severe drought events, climate change in arid regions has become one research hotspots. However, previous studies mainly focused on a specific region, and correlations differences among various have not been clearly understood. this study, based latest monthly gridded dataset CRU, we compare characteristics its relationship large-scale oceanic os...

We present the case of a 7-year old boy with traumatic brain injury who received propofol during 38 h. Thirty-six hours after cessation of propofol infusion asystole occurred. After immediate mechanical and medical resuscitation, unreactive dilated pupils were observed. The following computed tomography scan revealed a generalized brain edema with transtentorial herniation. Prolonged bradyarrhy...

Although pancreatic carcinoma and depression have been linked for many years, the prevalence and relationship of these two entities are still poorly understood. Published studies reviewing this issue have found that many patients with pancreatic cancer are depressed. A clinical gestalt asserts that many patients present with depression before pancreatic carcinoma is diagnosed. If the definition...

Consensus of opinion is rare in psychiatry. Even in the field of clinical trials, where experimentation is tightly controlled and regulatory bodies scrutinize the proof, controversies are frequent and difficult to resolve. One issue for which there is a widespread consensus is the unique place that clozapine occupies in the treatment of severe mental illnesses, particularly refractory schizophr...

The prognosis and risk factors for bronchiectasis are at present poorly known. The aim of this study was to examine the long-term prognosis and cause of death in this disease. The National Hospital Discharge Register was used to search for patients aged 35-74 yrs, with newly-diagnosed bronchiectasis in the period 1982-1986. Each of the 842 patients identified was matched with an asthmatic patie...

BACKGROUND Urachal carcinoma is an uncommon neoplasm associated with poor prognosis. CASE PRESENTATION A 45-year-old man was admitted with complaints of abdominal pain and pollakisuria. A soft mass was palpable under his navel. TC-scan revealed a 11 x 6 cm tumor, which was composed of a cystic lesion arising from the urachus and a solid mass component at the urinary bladder dome. The tumor wa...

Abstract Many populations of water fleas ( Daphnia ) are exposed to algal blooms dominated by microcystin‐producing cyanobacteria. However, the severity these effects on fitness remain poorly understood in natural populations. We investigated seasonal changes body size, reproduction and survival D . longispina individuals from five eutrophic lakes southern Sweden. tested whether collected befor...
