One of the most commonly used non-invasive methods for assessing human exposure to pollution is the analysis of human milk.Human milk analyses help estimate the exposure of infants[1].This is why breast milk is receives scientific interest,and various methods for determining different pollutants from the environment are being developed[2,3].

Response of Growth Dynamics of Two Spring Geophytes to Light Regime in a Lime-Beech Forest

Journal of Integrative Plant Biology 2006年第5期48卷 527-535页

Blomaee accumulation, leaf longevity and growth rate of two spring forest geophytes, Scllla blfolla L. and Arum maculatum L. were estimated separately for three size groups within each population of these species. Despite the differences in leaf longevity, both species showed a similar pattern of blomass accumulation In relation to their phenologles and reproductive demands. Eco-physlological acclimation to changing light environment was assumed through photosynthetic parameters and dynamics of leaf area Index In the predominant size group of each species. A light response curve was measured under natural light for each species through the continuum of Its phenology to quantify the photosynthetic photon flux density at light saturation, light-saturated photosynthetic rate, light compensation point, and dark respiration. Light-saturated assimilation per leaf area basis, dark respiration rate and light compensation points were significantly higher in S. blfolla relative to A. maculatum. However, the acclimation of photosynthesis that would respond to light changes in environment was not found in S. bifolla. In contrast, In A. maculatum a marked shift In the light dependence of photosynthesis through the season was noticed, which resulted In a strong photosynthetic acclimation to the low-light conditions. Accompanied by significant leaf area Index, this efficient low-light photosynthesis enabled greater leaf longevity, and consequently longer accumulative period to A. maculatum. From the different parameters that we determined （both photosynthetic acclimation and growth strategy） it would appear that these species belong to two distinct subgroups： S. blfolla to the early and A. maculatum to the late vernals.

Hepatic abscess secondary to a rosemary twig migrating from the stomach into the liver

引用

World Journal of Gastroenterology 2007年第41期13卷 5530-5532页

The ingestion of a foreign body that penetrates the gastric wall and migrates to the liver,where it causes an abscess is uncommon. A case of an ingested rosemary twig perforating the gastric antrum,then migrating to the liver,complicated by hepatic abscess and Staphylococcus aureus sepsis is reported. A 59-year-old man without a history of foreign body ingestion was admitted to our hospital because of sepsis and epigastralgia,which had progressively worsened. No foreign body was identified at preoperative imaging,but a rosemary twig was discovered during laparotomy. The liver abscess and sepsis were controlled successfully with surgery and antibiotics. This unusual condition should be kept in mind when dealing with cases of hepatic abscess,or even sepsis of unknown origin. Despite the improvement of non-surgical techniques such as percutaneous drainage and interventional endoscopy,surgery still remains important in the treatment of hepatic abscess caused by an ingested foreign body.

A candidate identification questionnaire (CIQ) was tested to determine its predictive value for patient-reported satisfaction in patients switched from once-weekly or once-daily treatment with a bisphosphonate to once-monthly dosing. This was a prospective, open-label, multicenter international study in patients with postmenopausal osteoporosis who had been receiving once-daily or once-weekly alendronate or risendronate for at least 3 months. Patients completed a CIQ, then commenced 150 mg monthly ibandronate for 6 months. Patients completed the Osteoporosis Patient Satisfaction Questionnaire (OPSAT-QTM) at baseline for 6 months. Scores were converted to composite satisfaction scores (CSS, scale 0-100). Totally 677 patients completed a CIQ, 645 were enrolled in the treatment phase and comprised the intent-to-treat (ITT) population, and 630 completed the study. In the ITT population, 68.1% patients answered “yes” to one or more CIQ questions. OPSAT-Q scores increased for the convenience, quality of life and overall satisfaction domains (p scores for the side effects domains were significant (p < 0.001) in the CIQ “yes” group, but not for the degree of bother (decrease in mean of 0.1 points, p = 0.50) or duration (no change, p = 0.84) of non-gastrointestinal side effects. Of 638 patients who completed the preference questionnaire, 93.0% of patients preferred the once-monthly dosing schedule and 563 patients (90.7%) found it more convenient. The most common adverse events were dyspepsia (1.9%), nausea (1.1%), and upper abdominal pain (0.9%). Patients are likely to prefer treatment with monthly ibandronate to a weekly or monthly bisphosphonate irrespective of their stated preference before switching treatment.
