“…Observed declines and even local extinctions of native fish populations in the bay have been attributed, fully or partially, to the invading fish (e.g., Jenkins and Burkhead 1993). In the late 1800s, the smallmouth bass, Micropterus dolomieu, was largely blamed for declines of shad, herring, minnows, and suckers in the Potomac River (Ferguson 1877). The introduction of M. dolomieu and other predatory species has been considered a factor in local extinctions of two small species of benthic fish, Percopsis omiscomaycus (or trout perch, formerly abundant but now extinct in the upper Potomac and Susquehanna Rivers) and Percina caprodes (or log-perch, extinct in the Potomac but still present in the Susquehanna).…”

Invasions by non‐indigenous species (NIS) are recognized as important stressors of many communities throughout the world. Here, we evaluated available data on the role of NIS in marine and estuarine communities and their interactions with other anthropogenic stressors, using an intensive analysis of the Chesapeake Bay region as a case study. First, we reviewed the reported ecological impacts of 196 species that occur in tidal waters of the bay, including species that are known invaders as well as some that are cryptogenic (i.e., of uncertain origin). Second, we compared the impacts reported in and out of the bay region for the same 54 species of plants and fish from this group that regularly occur in the regionÂ's tidal waters. Third, we assessed the evidence for interaction in the distribution or performance of these 54 plant and fish species within the bay and other stressors. Of the 196 known and possible NIS, 39 (20%) were thought to have some significant impact on a resident population, community, habitat, or process within the bay region. However, quantitative data on impacts were found for only 12 of the 39, representing 31% of this group and 6% of all 196 species surveyed. The patterns of reported impacts in the bay for plants and fish were nearly identical: 29% were reported to have significant impacts, but quantitative impact data existed for only 7% (4/54) of these species. In contrast, 74% of the same species were reported to have significant impacts outside of the bay, and some quantitative impact data were found for 44% (24 /54) of them. Although it appears that 20% of the plant and fish species in our analysis may have significant impacts in the bay region based upon impacts measured elsewhere, we suggest that studies outside the region cannot reliably predict such impacts. We surmise that quantitative impact measures for individual bays or estuaries generally exist for <5% of the NIS present, and many of these measures are not particularly informative. Despite the increasing knowledge of marine invasions at many sites, it is evident that we understand little about the full extent and variety of the impacts they create singly and cumulatively. Given the multiple anthropogenic stressors that overlap with NIS in estuaries, we predict NIS‐stressor interactions play an important role in the pattern and impact of invasions.

Lobar emphysema is a common cause of respiratory distress in infants accounting for approximately 50% of congenital lung malformations 13,14 . Pulmonary resectional procedures still represent the approperiate treatment for many pulmonary lesions.…”

Pulmonary resection is the operation that defines the thoracic surgeon. It represents the appropriate surgical treatment for many pulmonary lesions. This is the first study on pulmonary resection in Basrah, south of Iraq. The study is conducted in the Section of Thoracic and Cardiovascular Surgery in Basrah Teaching Hospital over a 5-year period (August 1996 to July 2001. The aim of the study is to present the personal experience of the author in lung resection, analyze the indications, surgical and anaesthetic management and outcome including morbidity and mortality in view of the literature. Thirty patients (17 males and 13 females) underwent pulmonary resection for different indications were retrospectively analyzed. The results of this study indicate that despite the small number of patients and the difficulties in anaesthetic management, pulmonary resection is practiced safely in Basrah, south of Iraq.

“…180,181 Ethylene acts alone or with SA and JA in the activation of the hypersensitive response, which triggers a long-lasting one, known as systemic acquired resistance, to provide immunity against subsequent infections caused by a broad spectrum of pathogens. 41,186 In contrast, certain pathogens influence ethylene production involved in plant defense for their own benefit. 159 The plant growth-promoting rhizobacteria produce microbial ACC deaminase, an enzyme hydrolyzing plant ACC, which decreases the ethylene-induced root growth inhibition during stress.…”
